Technical Field

The invention relates to drilling equipment, in particular to numerical control axial inner circumference drilling and tapping equipment.

Background

In machinery, screw holes (threaded holes) are collectively called screw through holes, and are used for mounting screws on a workpiece. The screw hole is internally provided with threads for threaded cooperation with a corresponding screw. The screw is a metal round rod with a head at one end and a thread at the other end. The nut is not needed, and the nut is directly screwed into the round hole with the thread on the part to connect or fix the position of the part.

In the process of machining a threaded hole, a low clearance is usually machined on a workpiece to be machined by using a drill as a tool, and then a thread is machined on the inner side of a bottom hole by using a tap as a tool (this process is called tapping).

The machining of threaded holes in conventional workpieces may be performed by drilling or tapping using equipment such as bench drills or milling machines, for example, to machine threaded holes in sheet metal. However, for the threaded hole machined in the inner side wall of the cylindrical workpiece, namely the threaded hole machined in the radial direction in the cylinder, the machining operation difficulty of the threaded hole is very high, if the diameter of the inner cylinder of the workpiece is small usually, people cannot directly enter the threaded hole, the threaded hole is inconvenient to hand, and the operation cannot be performed by a rotary table, a milling machine or other numerical control equipment, so that the difficulty is quite high.

Especially for the outer rotor barrel of a large-scale motor, the inner diameter space is only about 1 meter or smaller, the length is about 1.4 meters, and a plurality of threaded holes with strict arrangement rules and strict requirements on position and size precision are required to be arranged in the barrel. The design precision is usually that the size interval precision difference is plus or minus 0.1 millimeter, the circumference interval is only 6 angles or 12 angles, the difficulty of processing control is very big, if the processing deviation is big, the workpiece does not reach the standard, then the manufacturing cost including milling processing, material preparation and the like before is totally wasted, and the loss brought to enterprises is very big.

Therefore, the difficulty in processing the radial hole and the radial threaded hole in the inner side wall of the cylindrical workpiece is overcome, and equipment for manufacturing the special equipment for accurately processing the radial hole and the radial threaded hole in the inner side wall of the cylindrical workpiece is forced to be up to the standard.

However, for the threaded hole machined in the inner side wall of the cylindrical workpiece, namely the threaded hole machined in the radial direction in the cylinder, the machining operation difficulty of the threaded hole is very high, if the diameter of the inner cylinder of the workpiece is small usually, people cannot directly enter the threaded hole, the threaded hole is inconvenient to hand, and the operation cannot be performed by a rotary table, a milling machine or other numerical control equipment, so that the difficulty is quite high.

Especially for the outer rotor barrel of a large-scale motor, the inner diameter space is only about 1 meter or smaller, the length is about 1.4 meters, and a plurality of threaded holes with strict arrangement rules and strict requirements on position and size precision are required to be arranged in the barrel. The design precision is usually that the size interval precision difference is plus or minus 0.1 millimeter, the circumference interval is only 6 angles or 12 angles, the difficulty of processing control is very big, if the processing deviation is big, the workpiece does not reach the standard, then the manufacturing cost including milling processing, material preparation and the like before is totally wasted, and the loss brought to enterprises is very big.

Therefore, the numerical control axial inner circumference drilling and tapping equipment provided by the invention is used for professionally and accurately machining the radial hole and the radial threaded hole in the inner side wall of the cylindrical workpiece. And the device is controlled by setting a control system, so that the automatic, accurate and efficient processing of the radial hole and the radial threaded hole in the inner side wall of the cylindrical workpiece is realized.

As shown in fig. 3, the second support 31 is moved backward to leave the pedestal, so that the workpiece can be conveniently taken and placed. The conditions of the support stabilization and the machining operation are shown in fig. 2. And the front end of the pin shaft 33 is provided with a chamfer structure, so that the pin shaft can be conveniently and accurately inserted into the pin hole to be positioned and supported when approaching the butting flange. The stable effect of accurate support is reached.

Further, to facilitate the sliding control of the second connecting seat 28, the second moving driver includes two synchronizing wheels 34 arranged along the length direction of the shaft bracket 2, the synchronizing wheels 34 are rotatably disposed on the machine body 4, a compensating feed motor 35 is disposed on the machine body 4 and is in transmission connection with one of the synchronizing wheels 34 to drive the synchronizing wheels 34 to rotate, an annular synchronizing belt 36 is disposed to connect the two synchronizing wheels 34, and one side of the annular synchronizing belt 36 is rigidly connected to the second support 31.

Further, the V-shaped support 6 has two V-shaped supporting blocks 37 arranged along the length direction of the shaft bracket 2, a supporting seat 38 is arranged at the lower side of the V-shaped support 6, the supporting seat 38 can be slidably connected with the machine body 4 along the length direction of the shaft bracket 2, a compensation feed drive control supporting seat 38 is arranged on the machine body 4 to slide, telescopic push rods 39 are respectively arranged at two sides of the supporting seat 38 to control the V-shaped support 6 to ascend and descend, a first supporting rod 40 and a second supporting rod 41 are respectively arranged at two sides of the V-shaped support 6, one end of the first supporting rod 40 is hinged on the V-shaped support 6, one end of the second supporting rod 41 is hinged on the supporting seat 38, the first supporting rod 40 is hinged with the middle of the first supporting rod 40 in a crossed manner, the other end of the second supporting rod 41 is slidably connected with the V-shaped support 6, and the other end of the first supporting rod 40 is slidably connected with the supporting seat 38.

The V-shaped support block 37 supports the workpiece to facilitate automatic centering of the workpiece, and then the axial position of the workpiece is adjusted to coincide with the movable axial position of the spindle motor through the lifting of the telescopic push rod 39 to facilitate processing operation, so that the equipment is more suitable for processing workpieces with different lengths or shaft diameters, is particularly suitable for processing threaded holes on the inner side of outer rotor cylinders of large motors with various specifications, and the telescopic push rod 39 can be selected as a servo push rod. The mutual cooperation of the first stay 40 and the second stay 41 stabilizes the lifting balance of the V-shaped support 6 relative to the support seat 38 without torsion or position deflection. And the control precision is ensured.

Further, in order to ensure the sliding position accuracy of the V-shaped support 6, the compensation feed drive includes a fourth screw rod 42 rotatably disposed on the machine body 4, a fourth servo motor is disposed on the machine body 4 and is in transmission connection with the fourth screw rod 42, and a fourth screw nut is disposed on the support seat 38 and is in threaded fit connection with the fourth screw rod 42.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
