[0011] The third adjusting mechanism is located on the top of the workbench.

[0012] When in use, the circular metal piece is put on the limit plate, and then the operator rotates the limit block, so that the limit block and the limit plate move on the mounting rod toward the mounting plate. At the same time, the limit plate continuously squeezes the telescopic spring. Affected by the position of the connecting tube, the four limit clamps gather and limit the circumferential surface of the circular metal piece when moving toward the mounting plate.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0028] The utility model discloses a chamfering lathe for metal parts, which is mainly used in traditional chamfering lathes for metal parts, which are often designed in a relatively simple manner. Its tools, fixtures, workbenches and other components are all designed for chamfering of circular ring metal parts of specific specifications. Therefore, it is difficult to adapt to the chamfering cutting of circular ring metal parts of other specifications. In addition, if it is necessary to frequently replace tools, fixtures and other components to adapt to different chamfering specifications of circular ring metal parts, the production efficiency will be greatly reduced, and the wear and maintenance costs of the equipment will also increase.

[0029] Reference Figure 1 and Figure 4 A chamfering lathe for metal parts includes a workbench 1, a top outer wall of the workbench 1 is provided with a mounting box 2, a motor 18 is provided inside the mounting box 2, and further includes:

[0030] Clamping mechanism: installed at one end of the output shaft of the motor 18, the clamping mechanism includes a connecting tube, an inner wall of one side of the connecting tube is provided with a mounting plate 4, an outer wall of one side of the mounting plate 4 is provided with a mounting rod, one end of the mounting rod is provided with a thread, the mounting rod is connected to the limit plate through the thread, the outer wall of one side of the limit plate is fixedly connected to the limit block 21, a telescopic spring 19 is provided between the limit plate and the mounting plate 4, the telescopic spring 19 is wound around the circumferential outer wall of the mounting rod, the limit plate is a cylindrical structure, and the circumferential inner wall of the limit plate is hinged with four limit clamps 20;

[0032] The second adjusting mechanism: located on one side of the first adjusting mechanism;

[0033] The third adjustment mechanism: located on the top of the workbench 1.

[0034] It should be noted that the side of the limiting clip 20 facing the circular metal piece can be made of rubber material, which can adapt to circular metal pieces of different sizes and shapes and provide certain protection to prevent damage to the circular metal piece.

[0035] Among them, the limiting clamp 20 is an "L"-shaped structure, which is convenient for clamping the circular metal part and enhances the clamping effect.

[0036] In the specific implementation process, a controller 3 is provided on the top outer wall of the workbench 1 , and the controller 3 is electrically connected to the motor 18 , so that the operator can turn on or off the motor 18 .

[0037] Specifically, when in use, the circular metal piece is put on the limit plate, and then the operator rotates the limit block 21, so that the limit block 21 and the limit plate move on the mounting rod toward the mounting plate 4, and at the same time, the limit plate continuously squeezes the telescopic spring 19. Affected by the position of the connecting tube, the four limit clamps 20 gather and limit the circumferential surface of the circular metal piece when moving toward the mounting plate 4, and then start the motor 18. The output shaft of the motor 18 drives the connecting tube to rotate, thereby driving the circular metal piece to rotate. Under the mutual cooperation of the first adjusting mechanism, the second adjusting mechanism, and the third adjusting mechanism, the circular metal piece is chamfered. The device can limit and process circular metal pieces of different sizes, improve the practicability of the device, reduce the production cost of the enterprise, and improve production efficiency.

[0039] The gear ratio between the first gear 7 and the second gear 9 is 4:1.

[0040] Specifically, when in use, first turn the first knob to drive the second gear 9 to rotate. Since the first gear 7 and the second gear 9 are meshed with each other, the second gear 9 rotates and drives the first gear 7 to rotate at the same time, thereby adjusting the angle and tilt direction of the chamfering knife 8.

Under the limit of the inner wall of the mounting tube 10, the support block 17 is synchronously moved up and down on the circumferential outer wall of the second threaded rod 11.

The gear brake is mainly used to prevent the first gear 7 and the second gear 9 from shifting, and can effectively control the movement of the first gear 7 and the second gear 9 and achieve self-locking.

[0043] Specifically, when in use, first rotate the second knob to drive the third threaded rod 14 to rotate. Under the limiting action of the two limiting rods, the threaded sleeve 15 moves up and down on the circumferential outer wall of the third threaded rod 14. The set support rod 13 not only supports the mounting ring 12, but also realizes the interconnection between the mounting ring 12 and the threaded sleeve 15, thereby realizing the synchronous up and down movement of the first gear 7.

[0046] Working principle: When in use, first put the circular metal part on the limit plate, and then the operator rotates the limit block 21, so that the limit block 21 and the limit plate move toward the mounting plate 4 on the mounting rod, and at the same time, the limit plate continuously squeezes the telescopic spring 19. Affected by the position of the connecting tube, the four limit clamps 20 gather the circumferential surface of the circular metal part when moving toward the mounting plate 4, and the limit clamps 20 hold it. Then start the motor 18, and the output shaft of the motor 18 drives the connecting tube to rotate, thereby driving the circular metal part to rotate. Under the mutual cooperation of the first adjustment mechanism, the second adjustment mechanism, and the third adjustment mechanism, the circular metal part is chamfered.
