Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 8, the present invention provides an intelligent workpiece clamping system for a grinding machine, including a frame 10, a sliding seat 20 slidably connected to an upper surface of the frame 10, and clamping assemblies 30 fixed to both side surfaces of the sliding seat 20.

A rotating component 50 is arranged inside the sliding seat 20, and an execution end of the rotating component 50 is connected with the magnetic attraction fixing component 40 inside the sliding seat 20.

The sliding seat 20 includes a hollow sliding table 21 slidably connected to the upper surface of the frame 10, a first supporting bar 22 fixed to the inner wall of the top end of the hollow sliding table 21, and a second supporting bar 23 located at two sides of the first supporting bar 22 and fixed to the inner wall of the top end of the hollow sliding table 21 at equal intervals.

The clamping assembly 30 includes a supporting platform 31 fixed on one side surface of the sliding seat 20, an air cylinder 32 fixed on the upper surface of the supporting platform 31, and a mounting box 33 fixed on the piston rod at one end of the two air cylinders 32 close to each other, and a plurality of first telescopic clamping rods 34 arranged in an array are fixed inside the mounting box 33.

The magnetic attraction fixing assembly 40 includes a lifting frame 41 connected to an execution end of the rotation assembly 50 and disposed on two sides of the first supporting bar 22, a second telescopic clamping bar 42 fixed to an upper surface of the lifting frame 41, and an electromagnet 43 fixed to an upper surface of the second telescopic clamping bar 42. When the workpiece is actually clamped, the lifting frame 41 is driven by the rotation assembly 50 to rotate up and down so as to drive the workpiece to move horizontally on the upper surface of the sliding seat 20, and the workpiece is adsorbed and fixed by the electromagnet 43.

It should be noted that, in this embodiment, after the workpiece is placed on the lifting frame 41, the rotation assembly 50 drives the lifting frame 41 to rotate up and down, so that the workpiece moves along with the lifting frame 41 until the workpiece abuts against the first supporting bar 22 and the second supporting bar 23 at the top end of the hollow sliding table 21, and then the workpiece is continuously moved by the up and down rotation of the lifting frame 41. In the process, the second telescopic clamping rod 42 is arranged at the top end of the lifting frame 41, so that the second telescopic clamping rod 42 can adapt to the shapes of different workpieces in a telescopic mode, the movement of the workpieces is limited, and the workpieces are adsorbed and fixed through the electromagnet 43 at the top end of the second telescopic clamping rod 42.

Further, when the workpiece is moved to a position between the two mounting boxes 33, the two mounting boxes 33 are pushed to approach each other through the air cylinder 32 until the first telescopic clamping rod 34 on the mounting boxes 33 abuts against the workpiece, so that the first telescopic clamping rod 34 can stretch to adapt to workpieces of different shapes and clamp the workpieces.

Furthermore, when the grinding machine needs to give way to the positions on the two sides of the workpiece for machining, a worker can only adsorb and fix the bottom of the workpiece through the second telescopic clamping rod 42 and the electromagnet 43 at the top end of the lifting frame 41, so that enough space is given way for machining the workpiece, and the flexibility of clamping and fixing is improved.

Specifically, referring to fig. 2, 3 and 6, the shielding blade 24 is rotatably connected through the first rotating shaft 25, and the first rotating shaft 25 penetrates through the housing of the hollow sliding table 21 and is connected with the actuating end of the power assembly 60. It should be noted that, in this embodiment, the shielding blade 24 is rotated by the power assembly 60 until the shielding blade 24 maintains a horizontal state, and the shielding blade 24 shields the scraps splashed when the workpiece is machined by the grinding machine, so as to prevent the high-temperature scraps from entering the sliding seat 20 and damaging the workpiece in the sliding seat 20.

It can be understood that, when the shielding blade 24 is inclined downward by the rotation of the shielding blade 24, the scraps are dumped through the inclined surface caused by the downward inclination of the shielding blade 24, so as to be dumped into the sliding seat 20 for collection.

Specifically, the power assembly 60 includes a rotary plate 61 disposed on the outer periphery of the first rotating shaft 25 and located at one end of the hollow slide table 21, and a driven rod 62 rotatably connected to the bottom end of the rotary plate 61 through a rotating shaft. In addition, the power assembly 60 further includes a rotating plate 66 located at the top end of the first supporting bar 22 and rotatably connected to the housing of the hollow slide table 21 through a second rotating shaft 64, and an active rotating rod 63 fixed to the second rotating shaft 64 and extending to the outside end, wherein the end of the active rotating rod 63 remote from the second rotating shaft 64 is rotatably connected to the driven rod 62 through a rotating shaft.

In the present embodiment, when the first rotating shafts 25 rotate, the bottom end of the rotating disc 61 penetrating through each first rotating shaft 25 is connected to the driven rod 62 through a rotating shaft, so that the rotating discs 61 rotate synchronously through the driven rod 62.

Further, since the rotating plate 66 is disposed on the second rotating shaft 64, and one end of the driving rotating rod 63 on the second rotating shaft 64 is connected to the driven rod 62 through a rotating shaft, when the rotating plate 66 rotates under the pushing of the lifting frame 41, the driven rod 62 follows the rotating plate 66 to perform angular displacement.

Specifically, referring to fig. 2, fig. 3 and fig. 6, in another preferred embodiment of the present invention, an opening 67 is disposed at one end of the rotating plate 66 close to the second rotating shaft 64, and a torsion spring 65 sleeved on an outer surface of the second rotating shaft 64 is disposed in the opening 67.

The fixed end of the torsion spring 65 abuts against the upper surface of the first supporting bar 22, and the movable end of the torsion spring 65 abuts against the housing of the rotating plate 66. The shell of the rotating plate 66 is rotatably connected with a sliding wheel 68 through a rotating shaft, and the first telescopic clamping rod 34 and the second telescopic clamping rod 42 have the same structure.

The first telescopic clamping rod 34 includes a fixed rod 341 fixed inside the mounting box 33, and a movable rod 343 slidably connected to the fixed rod 341 and extending to the outside, wherein one end of the movable rod 343 extending to the fixed rod 341 is abutted with a spring 342.

In the present embodiment, when the lifting frame 41 pushes the rotating plate 66, the torsion spring 65 is sleeved on the second rotating shaft 64 of the rotating plate 66, and the fixed end of the torsion spring 65 abuts against the upper surface of the first supporting bar 22, and the movable end of the torsion spring 65 abuts against the housing of the rotating plate 66, so that the rotating plate 66 rotates by the energy stored in the torsion spring 65. Further, the rotating plate 66 is made to reduce dry friction between the lifting frame 41 and the rotating plate 66 by the rotation of the upper sliding wheels 68 on the lifting frame 41.

Further, when the cylinder 32 pushes the mounting box 33 to move, since the fixing rod 341 is disposed inside the mounting box 33, the movable rod 343 is slidably connected in the fixing rod 341, so that the movable rod 343 can slide on the fixing rod 341 to adapt to workpieces of different shapes. It should be noted that, since the spring 342 abuts against the movable rod 343, the spring 342 can be used to push the movable rod 343 to the original working position quickly.

Specifically, please refer to fig. 1, 2 and 4 again, in another preferred embodiment of the present invention, the infrared distance measuring devices 26 are symmetrically fixed on the upper surface of the hollow sliding table 21, the PLC controller 70 is fixed on one side surface of the frame 10, and the PLC controller 70 is connected to the infrared distance measuring devices 26 through wires.

It should be noted that, in the present embodiment, the size of the workpiece to be held is thereby estimated by the infrared distance meter 26. After the size of the workpiece to be clamped is estimated by using the infrared distance measuring instrument 26, the infrared distance measuring instrument 26 is connected with the PLC controller 70, and the PLC controller 70 is connected with the air cylinder 32 through a lead, so that the extension length of the piston rod of the air cylinder 32 is controlled by the PLC controller 70 to adapt to workpieces of different shapes.

The rotating assembly 50 includes first rotating blocks 51 disposed at two ends inside the hollow sliding table 21, one end of each first rotating block 51 is rotatably connected to the inner wall of the hollow sliding table 21 through a rotating shaft, and an electric telescopic rod 52 is embedded in the other end of each first rotating block 51. A second rotating block 53 is fixed at one end of the electric telescopic rod 52 far away from the first rotating block 51, and one end of the second rotating block 53 far away from the electric telescopic rod 52 is rotatably connected with the bottom end of the lifting frame 41 through a rotating shaft.

It should be noted that, in this embodiment, when the first rotating block 51 is driven to rotate by the motor connected to the first rotating block 51, the first rotating block 51 is connected to the second rotating block 53 at the bottom end of the lifting frame 41 through the electric telescopic rod 52, so that when the first rotating block 51 rotates, the lifting frame 41 rotates up and down.

Furthermore, the distance between the second rotating block 53 and the first rotating block 51 is controlled by the extension and contraction of the electric telescopic rod 52, so that when the scraps accumulated on the upper surface of the shielding blade 24 need to be removed, the distance between the second rotating block 53 and the first rotating block 51 is shortened, the pushing of the lifting frame 41 to the rotating plate 66 is released, and the shielding blade 24 is automatically inclined.

The specific operation mode of the invention is as follows:

when the intelligent clamping system is used for clamping a workpiece, the workpiece is firstly placed on the lifting frame 41, then the lifting frame 41 is driven to rotate up and down through the rotating assembly 50 so as to move along with the lifting frame 41 until the workpiece is abutted to the first supporting strip 22 and the second supporting strip 23 at the top end of the hollow sliding table 21, and then the workpiece is continuously moved through the up-and-down rotation of the lifting frame 41, in the process, as the second telescopic clamping rod 42 is arranged at the top end of the lifting frame 41, the telescopic action of the second telescopic clamping rod 42 is utilized to adapt to the shapes of different workpieces, the movement of the workpiece is limited, and then the workpiece is adsorbed and fixed through the electromagnet 43 at the top end of the second telescopic clamping rod 42;

when the workpiece is moved between the two mounting boxes 33, the two mounting boxes 33 are pushed to be close to each other through the air cylinder 32 until the first telescopic clamping rod 34 on the mounting boxes 33 abuts against the workpiece, so that the first telescopic clamping rod 34 can be used for adapting to workpieces of different shapes and clamping the workpieces;

the rotation amplitude of the lifting frame 41 is controlled by the expansion and contraction of the electric telescopic rod 52 in the rotation assembly 50, when the lifting frame 41 does not push the rotating plate 66, the rotating plate 66 rotates by means of the energy storage of the torsion spring 65 on the rotating plate, so that the second rotating shaft 64 on the rotating plate 66 drives the driven rod 62 to rotate through the driving rotating rod 63, and further drives the shielding blade 24 connected with the driven rod 62 to incline downwards, so that the shielding blade 24 shields scraps splashed when a workpiece is machined by the grinding machine, and the high-temperature scraps are prevented from entering the sliding seat 20 to damage the workpiece in the sliding seat 20;

through the rotation of sheltering from blade 24 for when sheltering from blade 24 downward sloping, topple over the sweeps through the inclined plane that shelters from the result of blade 24 downward sloping, in order to topple over the sweeps and collect in sliding seat 20.
