Description
Technical Field
[0001] The present invention relates to the technical field of production and processing of lathe gearboxes, and in particular to a processing device and method for a lathe gearbox housing. Background Art
[0002] The lathe gearbox is a transmission device installed inside the lathe, consisting of a gear set, shaft, bearing, housing and other components. It transmits power and converts parameters (speed, torque) through gear meshing. It is a key component for the lathe to complete cutting processing. The gearboxes usually used on machine tools are mainly rectangular gearboxes. During the production process, rectangular gearboxes need to be machined for reference surfaces and pores after casting. In the process of boring and opening holes in the gear box body, since the outer wall of the gear box body is relatively thin, the cutting force of boring and tapping directly acts on the thin wall of the gear box, which will cause the hole system to deform and the plane to warp. Finally, the coaxiality of the gear shaft will be out of tolerance after installation, causing transmission vibration and noise during use. Secondly, boring and tapping need to be carried out in steps, and a single clamping can only complete a single process, resulting in doubling the number of clamping times. There is an offset during the secondary clamping process, and manual secondary calibration is required, which prolongs the production cycle and is not convenient for large-scale production. In response to the above problems, the inventors proposed a lathe gear box body processing device and method to solve the above problems. Summary of the Invention

[0030] A processing method used in a processing device for a lathe gear box body comprises the following steps: S1. First, the cast lathe gearbox housing is deburred and aged. After the pretreatment, the housing reference surface is rough milled and planed, and the process reference holes for subsequent positioning are simultaneously machined. S2. The box body that has completed the basic rough machining is precisely fixed to the preset position of the work platform 3 using a special fixture for the gear box. The synchronous moving component 7 is started, and the synchronous positioning component 5 and the double-sided boring tool opening device 8 are driven to move synchronously toward the box body until they move to the processing position corresponding to the processing characteristics of the box body. S3, the support synchronous positioning component 5 extends into the inner cavity of the box to provide rigid support to the inner side of the box to prevent the box from being deformed due to the machining cutting force. At the same time, the thread opening component 6 is calibrated in space to ensure that it is vertically aligned with the hole to be tapped on the top of the box; S4, the double-sided boring tool opening device 8 performs finishing boring on the main shaft holes and gear shaft reference holes on both sides of the box body, and the thread opening component 6 performs tapping on the mounting hole area on the top of the box body; S5. After the tapping process is completed, the thread opening component 6 is controlled to retract and reset first. Then, the synchronous moving component 7 drives the supporting synchronous positioning component 5 and the double-sided boring tool opening device 8 to return to the initial position, loosen the fixture, take out the box, and transport it to the heat treatment section.
[0031] Working principle: In actual application, Figure 1 As shown, the pre-treated gear box body is fixedly installed at the preset position on the top of the working platform 3 by a special fixture to ensure the accurate positioning of the "one side and two holes" and the stability of the finishing; like Figure 2 、 Figure 8 and Figure 9 As shown, the control opens the lifting electric cylinder 705, and the lifting electric cylinder 705 drives the slide frame 4 to move downward along the vertical slide rail of the frame 1. During this process, the slide frame 4 drives the I-shaped plate 702 to move through the driving rod 704, and the I-shaped plate 702 then drives the double-sided workstation plates 701 to move synchronously toward the box body through the driven rod 703. When the two double-sided workstation plates 701 drive the corresponding boring tool opening device 8 to move to the corresponding position, the four lining plates 505 are located inside the gear box body, and then as shown in FIG. Figure 4As shown, the control opens the driving electric cylinder 513, and the driving end of the driving electric cylinder 513 extends to push the lifting rod 510 downward. The lifting rod 510 drives the two sliding frames 506 to slide away from each other along the bottom plate 503 through the connecting block 511 and the push rod 512. When the sliding frame 506 moves, the guide wheel at the top of the adjusting shaft 504 slides along the inclined groove 507 and the transverse groove 508, forcing the four adjusting shafts 504 to expand centripetally. The inner lining plate 505 presses against the inner wall of the box to provide rigid support for the inner wall of the gear box, offset the boring and tapping cutting forces, and prevent the box from deforming. In the process of the inner lining plate 505 pressing against the inner wall of the box, the adjusting frame 501 is driven to fine-tune under the guidance of the longitudinal plate 514 and the transverse plate 515 at the bottom of the sliding frame 4 to ensure that the thread cutter shaft 604 is vertically aligned with the hole to be tapped at the top of the box. After the double-sided boring tool opening device 8 arrives at the processing position with the synchronous moving component 7, the boring tool spindle is started to perform boring finishing on the spindle holes and gear shaft holes on both sides of the box body. At the same time, Figure 6 、 Figure 7 As shown, the main spindle motor 606 is controlled to be turned on, and the main spindle motor 606 drives the corresponding auxiliary shaft 605 to rotate through the coupling. The rotating auxiliary shaft 605 is linked with the thread cutter shaft 604 and other auxiliary shafts 605 through the synchronous wheel transmission group, driving all the thread cutter shafts 604 to rotate synchronously. Subsequently, the servo motor 610 rotates, and drives the screw rod 607 to rotate through the synchronous wheel transmission group. The screw rod 607 is threadedly matched with the guide ring 609 and the connecting plate 608 to drive the lifting plate 601 to rise and fall vertically along the outer wall of the adjustment frame 501 to adjust the height of the thread cutter shaft 604. By rotating the thread cutter shaft 604 and cooperating with the vertical feeding of the lifting plate 601, the mounting hole area on the top of the box is synchronously tapped. After the processing is completed, the servo motor 610 reverses, the screw rod 607 drives the lifting plate 601 upward, and the threaded cutter shaft 604 exits the tapping hole position. Then, the lifting electric cylinder 705 contracts, pulling the sliding frame 4 upward along the vertical slide rail of the frame 1; the synchronous moving component 7 is linked in reverse, and the I-shaped plate 702 and the work station plate 701 drive the boring tool hole opening device 8 away from the workpiece; the driving electric cylinder 513 contracts, and the adjustment shaft 504 contracts centripetally, loosening the inner wall support of the box, loosening the special clamp on the working platform 3, taking out the processed box, and transporting it to the heat treatment section.

Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
