Technical Field
The invention relates to machining equipment, in particular to a machine tool.
Background
The machine tool for cutting the product is characterized in that the product is clamped on a main shaft, the main shaft rotates to drive the product to rotate, and a cutter cuts the product. If the rotation center line of the main shaft has large deflection, so that the product cannot rotate around the center axis of the main shaft, the processing quality of the product by the cutter is influenced. Wherein, the rotation center line of main shaft has great beat, can be expressed as: the rotation center line of the main shaft during rotation is not perpendicular to the horizontal plane but is close to the vertical, so that the main shaft generates deflection during rotation.
Disclosure of Invention
The technical problems solved by the invention are as follows: how to improve the processing efficiency of the machine tool.
In order to solve the technical problems, the invention provides the following technical scheme: a double-spindle machine tool comprises a base, a machine tool cutting part arranged on the base and a machine tool spindle mechanism; the cutting part of the machine tool comprises a support, a translation frame, a lifting seat and a cutter device, wherein the support is arranged on a machine base, the translation frame is arranged on the support through a translation driving device, the lifting seat is arranged on the translation frame through a lifting driving device, the cutter device is arranged on the lifting seat, and the cutter device is provided with a cutter for cutting a product; the number of the machine tool spindle mechanisms is two, the two machine tool spindle mechanisms are arranged on the base in parallel, and the cutter can move between the two machine tool spindle mechanisms under the driving of the translation driving device.
According to the technical scheme, the tool can move to the position above the first spindle mechanisms of the two machine tool spindle mechanisms under the driving of the translation driving device, the lifting seat and the tool on the lifting seat descend under the driving of the lifting driving device, the first spindle mechanisms rotate to drive the products on the first spindle mechanisms to rotate, and the tool performs cutting processing on the products. After the machining is finished, the cutter is lifted and reset, the cutter moves to the position above the second spindle mechanism under the driving of the translation driving device and then descends to cut and machine the product on the second spindle mechanism.
When the cutter is used for processing a product on one of the two main shaft mechanisms, a worker can dismount the processed product on the other main shaft mechanism and clamp the product to be processed on the main shaft mechanism. Thus, the machining efficiency of the machine tool can be improved.
The machine tool spindle mechanism comprises a fixed part, a rotating part pivoted with the fixed part and a power part driving the rotating part, wherein a machine base of the machine tool is provided with a round hole, the fixed part is fixedly connected with the top of the round hole, the fixed part extends downwards into the round hole, a plurality of positioning bolts are screwed on the circumferential side wall of the fixed part, each positioning bolt is screwed with a positioning nut, the positioning bolt head is pressed against the side wall of the round hole, and the positioning bolts are fastened by the positioning nuts.
When the spindle mechanism is actually installed, after the spindle mechanism is assembled, namely the fixed part and the rotating part are assembled, the fixed part is fixedly connected with the top of the round hole, then the positioning bolt is rotated, the positioning bolt is screwed out of the outer side wall of the fixed part, the positioning bolt head is pressed against the side wall of the round hole, then the positioning nut is rotated, and the positioning nut is pressed against the outer side wall of the fixed part to fix the position of the positioning bolt.
Alternatively, the number of the positioning bolts is at least three, and a plurality of the positioning bolts are uniformly distributed along the circumferential side wall of the fixing part. Wherein, the lateral wall of fixed part is fixed partial circumference lateral wall promptly, and fixed partial lateral wall is circular.
The fixed part and the rotating part constitute a spindle of a spindle mechanism.
The main shaft mechanism and the base are in contact at two positions, the first position is the connection between the fixing part and the top of the round hole, and the second position is the contact between the positioning bolt on the fixing part and the side wall of the round hole. Wherein the first contact is located on the upper half of the fixed portion and the second contact is located on the lower half of the fixed portion.
The main shaft mechanism has the technical effects that: firstly, the fixed part can be effectively positioned by the positioning bolt, and then the rotating part is positioned, so that the rotating part can be prevented from generating deflection during rotation, or the deflection amplitude of the rotating part during rotation is reduced as much as possible; secondly, after the fixed part is fixedly connected with the base, the positioning bolt is adjusted to abut against the side wall of the circular hole, compared with the prior art that the fixed part is fixedly connected with the upper part and the lower part of the base, the invention can avoid the generation of stress in the fixed part and avoid the distortion and deformation of the fixed part when the fixed part is fixed with the base; thirdly, the bolt and the nut are adopted to position the fixed part, the material consumption is less, and the debugging and the dismounting of the bolt and the nut are more convenient.
