Description

Technical Field

[0001] This utility model relates to a gear quick-change fixture, belonging to the field of machining technology. Background Technology

[0002] A gear is a mechanical component typically used to transmit power and motion. It consists of two or more teeth and tooth spaces and is widely used in various equipment and machines. Gear machining often employs lathe fixtures to hold the gear assembly. Traditional gear shaft machining primarily uses fixtures for clamping, but these fixtures can only clamp axially and cannot perform machining operations perpendicular to the axial direction. Utility Model Content

[0003] The purpose of this invention is to provide a gear quick-change fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a gear quick-change fixture, comprising a base plate, a stand, a front clamping screw, a gear assembly to be processed, a limiting gear, a rear clamping assembly, and a gear limiting pin assembly. The stand is vertically welded and installed at the front and rear ends of the base plate. The front clamping screw is threaded onto the front stand, and the rear clamping assembly is positioned and installed on the rear stand. The front clamping screw and the rear clamping assembly position and clamp the gear assembly to be processed. The limiting gear of the gear assembly to be processed is coaxially positioned and installed. The limiting gear and the gear limiting pin assembly are vertically positioned and fixed.

[0005] Preferably, the gear limiting pin assembly consists of a stabilizing triangular plate, a mounting plate, a threaded cylinder, a clamping threaded rod, and a top block. The stabilizing triangular plate is positioned and welded to the bottom of the mounting plate, the threaded cylinder is positioned and welded to the top of the mounting plate, the threaded cylinder is threadedly connected to the clamping threaded rod, and a top block is positioned and installed at the top of the clamping threaded rod.

[0006] Preferably, the top block consists of a triangular top block, a support block, and an independent steering rod. The triangular top block and the support block are integrally machined and designed, and the independent steering rod is positioned and installed at the center of the rear end face of the support block.

[0007] Preferably, the rear clamping assembly consists of a tightening throttle, a drive threaded rod, and limit nuts. The tightening throttle is positioned at the top of the drive threaded rod, and two limit nuts are threaded onto the drive threaded rod.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The rear clamping assembly consists of a tightening throttle, a drive threaded rod, and a limit nut. Rotating the tightening throttle drives the drive threaded rod to feed the feed assembly and the front clamping screw to clamp the gear assembly to be processed. Tightening the limit nut fixes the position.

[0010] The gear limit pin assembly consists of a stabilizing triangular plate, a mounting plate, a threaded cylinder, a clamping threaded rod, and a top block. The top block consists of a triangular top block, a support block, and an independent steering rod. Rotating the clamping threaded rod drives the top block to clamp and engage with the limit gear, preventing irregular shaking during processing and ensuring the machining accuracy of the gear shaft. The electrically started machining machine performs machining operations on the gear shaft in the vertical and axial directions. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1-4 As shown, a gear quick-change fixture includes a base plate 1, a support frame 2, a front clamping screw 3, a gear assembly to be processed 4, a limiting gear 5, a rear clamping assembly 6, and a gear limiting pin assembly 7. The support frame 2 is vertically welded to the front and rear ends of the base plate 1. The front clamping screw 3 is threaded onto the front support frame 2. The rear clamping assembly 6 is positioned and installed on the rear support frame 2. The front clamping screw 3 and the rear clamping assembly 6 position and clamp the gear assembly to be processed 4. The limiting gear 5 of the gear assembly to be processed 4 is coaxially positioned and installed. The limiting gear 5 and the gear limiting pin assembly 7 are vertically positioned and fixed.

[0018] The gear limiting pin assembly 7 consists of a stabilizing triangular plate 8, a mounting plate 9, a threaded cylinder 10, a clamping threaded rod 11, and a top block 12. The stabilizing triangular plate 8 is positioned and welded to the bottom of the mounting plate 9. The threaded cylinder 10 is positioned and welded to the top of the mounting plate 9. The threaded cylinder 10 is threadedly connected to the clamping threaded rod 11. The top block 12 is positioned and installed at the top of the clamping threaded rod 11. Rotating the clamping threaded rod 11 drives the top block 12 to move inward and clamp and fix it to the limiting gear 5 to avoid irregular shaking during processing and ensure the processing accuracy of the gear shaft.

[0019] The top block 12 consists of a triangular top block 13, a support block 14, and an independent steering rod 15. The triangular top block 13 and the support block 14 are integrally machined and formed. The independent steering rod 15 is positioned and installed at the center of the rear end face of the support block 14. The triangular design of the triangular top block 13 ensures that the position is fixed and will not shake during the machining process.

[0020] The rear clamping assembly 6 consists of a tightening handle 16, a drive threaded rod 17, and a limiting nut 18. The tightening handle 16 is positioned at the top of the drive threaded rod 17. Two limiting nuts 18 are threaded onto the drive threaded rod 17. Rotating the tightening handle 16 drives the drive threaded rod 17 to feed and clamp the gear assembly 4 to be processed by the front clamping screw 3. Tightening the limiting nuts 18 fixes the position.

[0021] Specific usage: A gear quick-change fixture. This device is designed for structural optimization of gear quick-change fixtures. Rotating the tightening handle drives the threaded rod to feed and clamp the gear assembly to be processed by the front clamping screw. Tightening the limit nut fixes the position. Rotating the clamping threaded rod drives the top block to lock into place with the limit gear to avoid irregular shaking during processing, thus ensuring the processing accuracy of the gear shaft. The electrically started machining machine performs vertical and axial processing operations on the gear shaft.

[0022] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
