Technical Field

[0001] This utility model relates to the field of clamping fixture technology, specifically a clamping fixture for a drag chain wheel. Background Technology

[0002] Chain rollers (also known as guide rollers, support rollers, or idler rollers) are important components in mechanical transmission systems. They are mainly used to support and guide the operation of chains or tracks, and are primarily used for guiding, supporting, and transmitting power.

[0003] During the machining process, the cable chain wheel needs to be clamped to ensure that it does not move during processing, thereby avoiding affecting the machining accuracy. Existing clamping fixtures usually clamp the edge of the cable chain wheel. During processing, the cable chain wheel may move in the axial direction, which will affect the concentricity of the cable chain wheel.

[0004] Therefore, we propose a clamping fixture for cable pulleys to solve the problems mentioned above. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a clamping fixture for a sprocket, comprising a base plate 1, a moving mechanism 2 on the base plate 1, the moving mechanism 2 including a moving frame 21 slidably connected to both ends of the base plate 1, a positioning mechanism 3 on the moving frame 21 for positioning the center of the sprocket; a clamping mechanism 4 on the base plate 1 for clamping the edge of the sprocket; the positioning mechanism 3 including a transmission cylinder 33 with a conical surface; the positioning mechanism 3 also including a second electric push rod 32, the telescopic end of which is connected to the transmission cylinder 33; and the positioning mechanism 3 further including a plurality of clamping blocks 35 arranged in a ring, the clamping blocks 35 cooperating with the transmission cylinder 33.

[0023] Please see Figure 1 The moving mechanism 2 includes a lifting platform 25, which is slidably connected to the moving frame 21. A first electric push rod 24 is installed on the moving frame 21. The telescopic end of the first electric push rod 24 is connected to the lifting platform 25. A sliding groove 34 is provided on the mounting frame 31, and the transmission cylinder 33 is slidably connected in the sliding groove 34.

[0024] Please see Figure 1 , Figure 2The moving mechanism 2 also includes a motor 22, which is mounted on the base plate 1. The output end of the motor 22 is connected to a bidirectional lead screw 23, which is threadedly connected to two moving frames 21. The surface of the base plate 1 is also provided with a slide rail 26, and the moving frames 21 are slidably connected in the slide rail 26.

[0025] The movable mechanism 2 is used to drive the positioning mechanism 3 and the sprocket. The working principle of the movable mechanism 2 is as follows: the motor 22 drives the bidirectional lead screw 23 to rotate. The bidirectional lead screw 23 is threadedly connected to the two movable frames 21, so that the two movable frames 21 move towards or away from each other. The first electric push rod 24 drives the lifting platform 25 to move, and the lifting platform 25 drives the positioning mechanism 3 to move, thereby realizing the purpose of the positioning mechanism 3 and the sprocket. At the same time, the movable frame 21 is slidably connected in the slide rail 26. The slide rail 26 plays a guiding and limiting role on the moving trajectory of the movable frame 21, ensuring the stability of the moving frame 21. The first electric push rod 24 drives the lifting platform 25 to move, and the lifting platform 25 drives the positioning mechanism 3 to rise and fall, thereby realizing the height adjustment of the positioning mechanism 3, which facilitates the cooperation between the positioning mechanism 3 and the sprocket.

[0026] Please see Figure 3 The positioning mechanism 3 also includes a mounting frame 31, which is fixedly connected to the lifting platform 25. The second electric push rod 32 is mounted on the mounting frame 31. The mounting frame 31 is connected to a fixing plate 37, and the fixing plate 37 and the clamping block 35 are elastically connected.

[0027] Please refer to the figure. Figure 3 , Figure 4 The fixing plate 37 is connected to a limiting rod 38, and the clamping block 35 is provided with a corresponding insertion hole for the limiting rod 38. A spring 36 is connected in the insertion hole, and the spring 36 is connected to the limiting rod 38.

[0028] Please see Figure 4 A positioning ring 303 is fixedly connected to the clamping block 35. A movable groove is provided on the positioning ring 303. A movable plate 301 is slidably connected in the movable groove. A third electric push rod 39 is installed on the clamping block 35. The telescopic end of the third electric push rod 39 is connected to the movable plate 301. A limit ring 302 is connected to the end of the movable plate 301 away from the third electric push rod 39.

[0029] The positioning mechanism 3 is used to fix the sprocket's shaft. The positioning mechanism 3 clamps the inner wall of the sprocket's center hole through the positioning ring 303, and then positions the sprocket's surface through the limiting ring 302, thereby achieving multi-directional positioning of the sprocket and ensuring that the sprocket will not shift during processing. The working principle of the positioning mechanism 3 is as follows:

[0030] The second electric push rod 32 drives the transmission cylinder 33 to move, and the transmission cylinder 33 drives multiple clamping blocks 35 to move, so that the multiple clamping blocks 35 cooperate with each other to clamp and fix the shaft of the sprocket. When the clamping blocks 35 move, they drive the positioning ring 303 to move, so that the positioning ring 303 cooperates with the inner wall of the center hole of the sprocket. The third electric push rod 39 drives the moving plate 301 to move, and the moving plate 301 drives the limiting ring 302 to move, so that the limiting ring 302 cooperates with the surface of the sprocket, thereby realizing multi-directional positioning of the sprocket. At the same time, when the clamping blocks 35 move, they drive the spring 36 to compress or stretch. The reaction force of the spring 36 makes the clamping blocks 35 fix the sprocket more stably.

[0031] Please see Figure 5 The clamping mechanism 4 includes a connecting frame 41, which is fixedly connected to the base plate 1. A fixing rod 42 is connected to the base plate 1. A fixing clamping plate 43 is fixedly connected to the end of the fixing rod 42 away from the base plate 1. A movable clamping plate 44 is slidably connected to the connecting frame 41. A fourth electric push rod 45 is installed on the connecting frame 41. The telescopic end of the fourth electric push rod 45 is connected to the movable clamping plate 44.

[0032] The clamping mechanism 4 is used to clamp the edge of the sprocket. The working principle of the clamping mechanism 4 is that the fourth electric push rod 45 drives the moving clamping plate 44 to move, so that the moving clamping plate 44 and the fixed clamping plate 43 cooperate with each other to clamp and fix the edge of the sprocket.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
