Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to an integrated clamping mechanism applied to a gear shaft processing process. Background Art

[0002] A gear shaft refers to a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. It is usually in the shape of a metal round rod, and each section can have different diameters. The parts that rotate in the machine are mounted on the shaft. The main function of a gear shaft is to transfer power from one shaft to another through the meshing of gears, while changing the speed or direction.

[0003] For example, the application number is 202410853477.8, and it is named “A gear shaft clamping and processing equipment”. The clamping device includes a support rod, which is fixedly mounted on a mounting plate. The support rod is provided with a clamping component one and a clamping component two, and the two clamping components clamp the upper and lower ends of the gear shaft respectively. Specifically, the clamping component one and the clamping component two are used to clamp the gear shaft at the same time, and secondly, the gear shaft can also be clamped alternately. However, each time the rotating gear shaft is switched to the next gear to be processed, the clamping component needs to loosen the flexible clamping of the gear shaft, and because the round and smooth outer wall of the gear shaft is prone to slight deflection when clamped again, the processing accuracy is low.

[0004] This case was created to solve the above problems. Summary of the invention

[0016] (III) Beneficial effects

[0017] After adopting the above technical solution, the integrated clamping mechanism applied to the gear shaft processing process provided by the present invention has the following beneficial effects compared with the prior art:

DETAILED DESCRIPTION

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] See attached Figure 1-4 As shown, an integrated clamping mechanism used in the gear shaft processing process can be used to clamp gear shafts 7 of different diameters, and the clamping position can be switched in real time during clamping. It includes a frame 1, and clamping mechanisms 6 are respectively provided on both sides of the frame 1, and a rotating seat 2 is provided at the bottom. The rotating seat 2 is rotated by a built-in stepping motor, and the axial center of the rotating seat 2 is located inside the clamping output position of the two clamping mechanisms 6. The clamping mechanisms 6 are one high and one low and are located on both sides of the gear shaft 7 for limited clamping. The rotating seat 2 is movably equipped with a model sleeve 4 to insert the gear shaft 7, and a clamp is built into the bottom of the rotating seat 2, which tightens the inner wall of the inserted gear shaft 7 to limit the position.

[0029] The XY axes of the frame 1 are respectively provided with a cylinder 1 9 and a cylinder 2 10. The output end of the cylinder 1 9 is vertically downward and connected to a slide bar 17. The slide bar 17 is slidably connected to the cylinder 2 10. The output end of the cylinder 2 10 is connected to a conventional cutting mechanism 8 through a mounting block. The cutting of the gear shaft 7 is achieved by adjusting the height and horizontal position.

[0030] The clamping mechanism can solve the following problems: 1. It can solve the problem of uniform clamping of gears of different sizes at different positions on the upper and lower shafts of the gear shaft 7; 2. It can solve the problem of deflection margin each time the gear shaft 7 rotates to the corresponding tooth position; 3. It can solve the problem of synchronously fixing the position when the gear shaft 7 rotates to switch the processing position to avoid deviation.

[0031] The model gear sleeve 4 has the same gear module, number of teeth, backlash, pitch circle diameter, etc. as the gear shaft 7 to be processed. By limiting the position of the model gear, the precise processing of the gear shaft 7 is indirectly achieved.

[0032] The clamping mechanism 6 includes an L-shaped fixed seat 61, and a movable seat 62 is slidably connected to both sides of the inner wall of the fixed seat 61. The two sides of the movable seat 62 form inclined surfaces, and a gap is formed between the fixed seat 61. The two sides of the end surface of the fixed seat 61 are hinged with clamping blocks 65, and the ends of the clamping blocks 65 are respectively connected to clamping heads 67. The clamping heads 67 are abutted against the outer walls of the two sides of the gear shaft 7. The gear shafts 7 of different sizes can be clamped by adjusting the rotation angle of the clamping blocks 65. A notch is provided on the outer side of the movable seat 62, and a cylinder 3 610 is installed on the inner wall of the frame 1. A push block 64 is connected to the output end of the cylinder 3 610 and the notch of the movable seat 62. A connecting seat 68 is provided at the inner side end of the movable seat 62, and a clamping wheel 69 is pivotally connected to the connecting seat 68, and the clamping wheel 69 abuts against the gear shaft 7.

[0033] A flexible washer may be sleeved on the outer ring of the clamping wheel 69 to increase the flexible contact area with the gear shaft 7 , further improving the clamping stability and avoiding hard scratches on the gear shaft 7 .

[0034] When in use, the cylinder three 610 pushes the movable seat 62 to move inward so that the clamping seat abuts against the gear shaft 7. At the same time, the clamping head 67 rotates inward to retract and engage the gear shaft 7. When the gear processing position of the gear shaft 7 is rotated and switched, the movable seat 62 moves the clamping block 65 outward to loosen the limit on the gear shaft 7.

[0035] It should be noted that if the attached Figure 5 As shown, the center axis of the clamping head 67 is located relatively outside the center axis of the gear shaft 7, that is, when the clamping head 67 is driven to rotate inward, the gear shaft 7 can be embraced, and the clamping structures on both sides can bidirectionally embrace the gear shaft 7 to achieve tight fixation.

[0036] See attached Figure 3 As shown, the clamp includes a micro cylinder 5 horizontally placed on the rotating seat 2, whose output end is connected to the connecting rod 13. Under normal conditions, the inner end of the connecting rod 13 is placed in the middle of the rotating seat 2 and is connected to a top block 14. The outer side of the top block 14 is arranged in an arc shape, which is more conducive to fitting the inner wall of the gear shaft 7.

[0037] The rotating seat 2 is provided with an annular inserting seat 15, the model sleeve gear 4 is inserted into the inserting seat 15, a hollow support sleeve 16 is inserted into the inserting seat 15, and a vacancy is formed at the bottom for the connecting rod 13 to be placed, and the top block 14 is located in the support sleeve 16. It should be noted that the inner diameter of the support sleeve 16 is larger than the inner diameter of the gear shaft 7, so that the top block 14 can be adjusted in position through the cylinder output and can be pressed against the inner wall of the gear shaft 7.

[0038] See attached Figure 6 As shown, a positioning member 3 is installed on the rotating seat 2, and the positioning member 3 is placed on the side of the model sleeve gear 4, which includes a bracket 31 fixed to the rotating seat 2, and a spring 32 is built in the bracket 31. One end of the spring 32 is connected to the inner end of the bracket 31 through a connector 33, and the other end is connected to an insert 34. Both sides of the insert 34 are connected to moving blocks 35, and the moving blocks 35 are slidably connected to both sides of the bracket 31. When used, each time a gear tooth is rotated, the insert 34 is inserted into it under the action of the spring 32, and one side of the insert 34 is a beveled surface, which can be smoothly disengaged after the gear rotates and quickly enter the next tooth gap driven by the spring 32.

[0039] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
