Description

Technical Field

[0001] This utility model relates to the field of gear ring processing technology, specifically a gear ring clamping device for a speed reducer. Background Art

[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine. Among them, the gear ring that meshes with the gear is a common component in mechanical equipment. During various processing of the gear ring, clamping and positioning devices are often required to fix it.

[0003] A gear ring clamping device, as described in application number CN202220763442.1, includes a worktable, a fixed plate, a sliding groove, grippers, and a power assembly. The gear ring to be clamped is positioned in the center of the grippers. A cylinder is activated to drive a connecting rod, which in turn moves the grippers downwards, thus clamping the gear ring and securing it. When it is necessary to release the gear ring, the cylinder pushes the connecting rod, causing the grippers to move upwards, thereby releasing the gear ring. This device is suitable for clamping gear rings of different sizes without requiring replacement, making it easy to operate and cost-effective.

[0004] When the gear ring clamping device proposed in the aforementioned patent is in use, the cylinder pushes the connecting rod to drive the gripper to fix the gear ring. This setting means that when the operator needs to move the fixed position of the gear ring, the cylinder drives the connecting rod to move backward, causing the gripper to loosen its grip on the gear ring. If the operator does not hold the gear ring, it will fall off.

[0005] Therefore, we propose a gear ring clamping device for a speed reducer to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a gear ring clamping device for a speed reducer, so as to solve the problem mentioned in the background art that when the operator needs to move the fixed position of the gear ring, the cylinder drives the connecting rod to move backward, causing the gripper to loosen its grip on the gear ring, and if the operator does not hold the gear ring, the gear ring will fall off.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a gear ring clamping device for a speed reducer, comprising a worktable and a fixing plate fixedly installed on one side of the upper end of the worktable, a power component being provided on one side of the upper end of the worktable, clamping components being provided at the four corners of one end of the power component, a positioning component being threadedly fixedly installed on one end of the outer wall of the clamping component, and a counter-aligning component being fixedly installed at both ends of the fixing plate, the counter-aligning component being adapted to pre-fix and support the gear ring;

[0008] The positioning component includes a fixing mechanism and an extension mechanism fixedly installed on one side of the upper end of the fixing mechanism. The fixing mechanism drives the extension mechanism to adjust the setting length, and the extension mechanism is adapted to limit and fix the inner wall of the gear ring.

[0009] Preferably, the clamping assembly includes a gripper and a mounting plate fixedly installed at the middle of one end of the outer wall of the gripper.

A T-shaped connecting rod is fixedly installed at the lower end of the arc-shaped rod, and a round abutment block is fixedly installed at one end of the T-shaped connecting rod. A ball bearing is movably embedded in the middle of the inner cavity of the round abutment block.

[0012] Preferably, the top assembly includes a fixing block and an electrically operated telescopic column fixedly installed at the middle of one end of the fixing block.

[0013] Preferably, a clamping plate is fixedly installed at one end of the electric telescopic column, and an anti-slip rubber layer is embedded in one end of the clamping plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. After the gripper fixes the gear ring, adjust the height of the threaded rod on the upper end of the mounting plate according to the set height of the gear ring. Adjust the second miniature electric telescopic column to drive the T-shaped connecting rod, the T-shaped connecting rod and the round abutment block to clamp the inside of the gear ring.

In this state, the operator can directly rotate the gear ring to adjust the angle and position, which is convenient to use.

[0016] 2. When the operator clamps and fixes the gear ring, the gear ring is placed in the middle of one side of the fixing plate. The clamping plate is extended by activating the electric telescopic column. The clamping plate limits and fixes the two sides of the outer wall of the gear ring to achieve pre-fixation of the gear ring. Attached Figure Description

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1-3 A gear ring clamping device for a speed reducer includes a worktable 1 and a fixing plate 2 fixedly installed on one side of the upper end of the worktable 1. A power component 3 is provided on one side of the upper end of the worktable 1. Clamping components 4 are respectively provided at the four corners of one end of the power component 3. A positioning component 5 is threadedly fixedly installed on one end of the outer wall of the clamping component 4. A counter-alignment component 6 is fixedly installed on both ends of the fixing plate 2. The counter-alignment component 6 is suitable for pre-fixing and supporting the gear ring.

[0024] The positioning component 5 includes a fixing mechanism 51 and an extension mechanism 52 fixedly installed on one side of the upper end of the fixing mechanism 51. The fixing mechanism 51 drives the extension mechanism 52 to adjust the setting length, and the extension mechanism 52 is adapted to limit and fix the inner wall of the gear ring.

[0025] The clamping assembly 4 includes a gripper 41 and a mounting plate 42 fixedly installed at the middle of one end of the outer wall of the gripper 41.

[0026] The fixing mechanism 51 includes a threaded rod 511 and a disc 512 fixedly installed on one side of the upper end of the threaded rod 511. The upper and lower ends of the outer surface of the threaded rod 511 are respectively threaded with fixing nuts 513. The threaded rod 511 is movably installed in the middle of the inner cavity of the mounting plate 42.

[0027] The threaded rod 511 is threadedly fixed to the upper middle part of the mounting plate 42 by the fixing nuts 513 that are threaded to the upper and lower ends of its outer surface.

[0028] The extension mechanism 52 includes a second miniature electric telescopic column 521 and an arc-shaped rod 522 fixedly installed at one end of the second miniature electric telescopic column 521. A T-shaped connecting rod 523 is fixedly installed at the lower end of the arc-shaped rod 522. A round abutment block 524 is fixedly installed at one end of the T-shaped connecting rod 523. A ball bearing 525 is movably embedded in the middle of the inner cavity of the round abutment block 524. The second miniature electric telescopic column 521 drives the arc-shaped rod 522, the T-shaped connecting rod 523 and the round abutment block 524 to press the inside of the gear ring against one side of the clamp 41 and limit and fix it.

[0029] The ball bearing 525 is designed to reduce the friction between the round abutment block 524 and the inside of the gear ring.

[0030] In this embodiment: the power assembly 3 drives the four corner grippers 41 at one end to clamp and fix the outer wall of the gear ring. After the gear ring is fixed by the grippers 41, the operator can adjust the height of the threaded rod 511 on the upper end of the mounting plate 42 according to the set height of the gear ring. Then, the upper and lower ends of the threaded rod 511 are threaded and fixed to the mounting plate 42 by the nuts. The second micro electric telescopic column 521 is adjusted to drive the T-shaped connecting rod 523, the T-shaped connecting rod 523 and the round abutment block 524 to clamp the inside of the gear ring. When the operator needs to move the clamped gear ring, the grippers 41 are slightly adjusted to loosen the grip on the outer wall of the gear ring. The gear ring will not fall off the grippers 41 under the pressure of the round abutment block 524. In this state, the operator can directly rotate the gear ring to adjust the angle and position, which is convenient to use.

[0031] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 The top assembly 6 includes a fixing block 61 and an electric telescopic column 62 fixedly installed at the middle of one end of the fixing block 61. The top assembly 6 is located on one diagonal side of the fixing plate 2.

[0032] A clamping plate 63 is fixedly installed at one end of the electric telescopic column 62. An anti-slip rubber layer 64 is embedded in one end of the clamping plate 63 to improve the friction between the clamping plate 63 and the outer wall of the gear ring.

[0033] In this embodiment: when the operator clamps and fixes the gear ring, the gear ring is placed in the middle of one side of the fixing plate 2, and the clamping plate 63 is extended by activating the electric telescopic column 62. The clamping plate 63 limits and fixes the two sides of the outer wall of the gear ring to achieve pre-fixation of the gear ring.

[0034] Working principle: The gear ring is placed in the middle of one side of the fixed plate 2. By activating the electric telescopic column 62, the clamping plate 63 is extended, and the clamping plate 63 limits and fixes the outer wall of the gear ring on both sides. Then, the power component 3 is activated to drive the four corner grippers 41 at one end to clamp and fix the outer wall of the gear ring. After the gear ring is fixed by the grippers 41, the operator can adjust the setting height of the threaded rod 511 on the upper end of the mounting plate 42 according to the setting height of the gear ring. Then, the second micro The electric telescopic column 521 drives the T-shaped connecting rod 523, which, along with the round abutment block 524, clamps the inside of the gear ring. When the operator needs to move the clamped gear ring, the gripper 41 is slightly loosened by fine adjustment, allowing it to slightly loosen its grip on the outer wall of the gear ring. At the same time, the inner wall of the gear ring will not fall off the gripper 41 under the pressure of the round abutment block 524. In this slightly loose state, the operator can directly rotate the gear ring to adjust the angle and position, making it convenient to use.

[0035] The structure and working principle of the power assembly and clamping assembly are the same as those of the gripper, guide bar, power assembly, cylinder, connecting rod, limit flange, rubber pad, connecting block, limit groove and connecting ear in publication number CN217453598U, and will not be described again here.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
