Description

Technical Field

[0001] The utility model relates to the technical field of automobile piston drilling, in particular to an automobile piston chamfering and drilling device. Background Technique

[0002] The automobile piston is an important component in the automobile engine, and it bears high temperature, high pressure and high-speed friction during the working process of the engine. In order to improve the performance and service life of the piston, it is necessary to carry out processing such as chamfering and drilling on it.

[0003] In the patent application with the authorization publication number CN218015917U, the authorization publication date of December 13, 2022, and the name "A Drilling Device for Automobile Piston Processing", the piston in the limiting groove can be clamped by setting a fixed block and a moving block under the control of a hydraulic cylinder, so as to facilitate the drilling machine to process the piston. When the output end of the hydraulic cylinder pulls the moving block and the moving block presses on the piston, the moving block will approach the limiting plate. When the moving block moves to a certain position of the limiting plate, the hydraulic cylinder will be controlled to stop working through a proximity switch, so that the moving block stops applying pressure to the piston and the piston will not be damaged;

[0004] In the actual use process of the above device, the piston is fixed by fitting into the limiting grooves opened inside the fixed block and the moving block. However, for pistons of different models, this clamping method has the problem of poor stability, and it is inconvenient to adjust the angle of the piston according to actual needs, reducing the practicability.

[0005] Therefore, we propose an automobile piston chamfering and drilling device to solve the problems raised above. Content of the Utility Model

[0010] The upper end surface of the workbench is fixed with a mounting plate, and a workpiece fixing mechanism is installed on the front side of the mounting plate, and the workpiece fixing mechanism is used for fixing the automobile piston;

[0011] A groove is formed on the upper end surface of the workbench, and a movable plate is slidably installed in the groove. A rotating plate is rotatably installed on the movable plate, and an adjusting member is installed between the rotating plate and the movable plate. The adjusting member is used to drive the rotating plate to rotate. The lower side of the movable plate is connected to the output end of the electric push rod, and the electric push rod is fixedly installed below the tabletop of the workbench.

[0012] Furthermore, the workpiece fixing mechanism includes a base rotatably installed on the front side of the mounting plate.

[0014] Furthermore, the driving member includes a first worm and a first worm gear that mesh with each other. The first worm is installed by bearings inside the base, and the first worm gear is sleeved and fixed on the rotating shaft of the turntable.

[0015] Through the above technical solution, when the first worm rotates, it can drive the first worm gear and the turntable to rotate.

[0016] Furthermore, the clamping member is composed of an L-shaped clamping block, an I-shaped block, and a roller. The L-shaped clamping block is fixedly installed at the front end of the I-shaped block, and the roller is rotatably installed at the rear end of the I-shaped block. The I-shaped block and the roller are respectively arranged in a sliding and fitting manner inside a first chute and a second chute.

[0035] Please refer to Figures 1-4, An automotive piston chamfering and drilling device, including a workbench 1. Above the workbench 1, a Z-axis displacement module 2 is installed. An X-axis displacement module 3 is movably installed on the Z-axis displacement module 2, and a Y-axis displacement module 4 is movably installed on the X-axis displacement module 3. And a chamfering and drilling module 12 for chamfering and drilling automotive pistons is movably installed on the Y-axis displacement module 4; A mounting plate 5 is fixed on the upper end surface of the workbench 1, and a workpiece fixing mechanism 6 is installed on the front side of the mounting plate 5. The workpiece fixing mechanism 6 is used to fix the automotive piston; The workpiece fixing mechanism 6 includes a base 61 rotatably installed on the front side of the mounting plate 5. Inside the base 61, a turntable 62 is rotatably installed. And a driving member 63 is installed on the rear side of the shaft end of the turntable 62. And a clamping member 64 is slidably installed at equal angles on the front side of the turntable 62; The driving member 63 includes a first worm 631 and a first worm gear 632 that mesh with each other. The first worm 631 is installed by bearings inside the base 61, and the first worm gear 632 is sleeved and fixed on the rotating shaft of the turntable 62; The clamping member 64 is composed of an L-shaped clamping block 641, an I-shaped block 642, and a roller 643. The L-shaped clamping block 641 is fixedly installed at the front end of the I-shaped block 642, and the roller 643 is rotatably installed at the rear end of the I-shaped block 642. And the I-shaped block 642 and the roller 643 are respectively fitted and slidably arranged inside the first chute 65 and the second chute 66. Moreover, the first chute 65 and the second chute 66 are respectively opened inside the base 61 and the turntable 62. At the same time, the second chute 66 is arranged in an inclined shape;

[0036] First, place the automotive piston between several clamping members 64, and then rotate the first worm 631. The first worm 631 drives the first worm gear 632 to rotate by virtue of the meshing action with the first worm gear 632. Since the first worm gear 632 is coaxial with the turntable 62, the first worm gear 632 can drive the turntable 62 to rotate. When the turntable 62 rotates, by virtue of the fitting action between the second chute 66 and the roller 643, the clamping member 64 is driven to move. Under the fitting and sliding action between the first chute 65 and the I-shaped block 642, the clamping member 64 moves towards the side surface of the automotive piston to position and clamp the automotive piston, realizing the fixing effect on the automotive piston and avoiding the offset of the automotive piston during the processing, which affects the processing effect;

[0037] A groove 7 is opened on the upper end surface of the workbench 1, and a movable plate 8 is slidably installed in the groove 7.

[0038] After the workpiece fixing mechanism 6 fixes the rear end of the automobile piston, the electric push rod 11 is started to drive the movable plate 8 to move toward the front end of the automobile piston as a whole until the rubber pad 91 on the rotating plate 9 is tightly attached to the front end of the automobile piston. When the drilling angle of the automobile piston needs to be adjusted, the worm gear 102 is rotated, and the meshing action between the worm gear 102 and the worm wheel 101 is used to drive the worm wheel 101 to rotate. The worm wheel 101 can drive the rotating plate 9 to rotate, and the automobile piston located between the rotating plate 9 and the workpiece fixing mechanism 6 can rotate synchronously to achieve angle adjustment and improve practicality.

[0039] Working principle: When using the automobile piston chamfering and drilling equipment, Figures 1-4 As shown, firstly, the automobile piston is placed between several clamping members 64, and then the worm 1 631 is rotated to drive the turntable 62 to rotate, and the clamping member 64 is driven to move toward the side surface of the automobile piston by utilizing the fitting effect between the second slide groove 66 and the roller 643 and the fitting sliding effect between the first slide groove 65 and the I-block 642, so as to position and clamp the automobile piston, thereby achieving the fixing effect on the automobile piston, and avoiding the automobile piston from shifting during the processing, thereby affecting the processing effect. After the workpiece fixing mechanism 6 fixes the rear end of the automobile piston, the electric push rod 11 is started to drive the rubber pad 91 on the rotating plate 9 to be close to the front end of the automobile piston. When the drilling angle of the automobile piston needs to be adjusted, the worm 2 102 is rotated to drive the automobile piston to rotate synchronously, thereby achieving angle adjustment and improving practicality.
