Description

Technical Field

[0001] This utility model belongs to the field of chain plate processing and assembly technology, and in particular relates to a positioning and clamping tool for chain plate assembly. Background Technology

[0002] Chain conveyors are common load-bearing components in automated conveyor lines, widely used in continuous material transport scenarios. They typically have a flat or hinged structure with toothed grooves at the bottom that mesh with the drive mechanism. Multiple chain conveyors are usually connected sequentially by pins to form a closed-loop conveyor belt. During conveyor operation, the chain conveyors achieve continuous transmission through the meshing of the bottom toothed grooves with the drive mechanism, thereby carrying and transporting materials.

[0003] In existing chain plate assembly processes, positioning and clamping fixtures are often required to press adjacent chain plates into place. However, traditional positioning and clamping fixtures are mostly fixed structures, making it difficult to adapt to the assembly requirements of chain plates of different specifications. When the chain plate model is changed, the entire set of positioning elements often needs to be replaced, resulting in poor versatility and inconvenient adjustment. Secondly, the existing fixtures use relatively simple positioning methods for the chain plates, mostly relying on the outer contour for coarse positioning, leading to insufficient positioning accuracy. During the pressing process, the chain plates are prone to displacement, which in turn affects the pressing position accuracy of the pins, causing unstable assembly quality. Therefore, it is necessary to design a chain plate assembly positioning and clamping fixture that is versatile, accurate in positioning, and easy to adjust. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a positioning and clamping fixture for chain plate assembly, which aims to solve the problems mentioned in the background art.

[0005] The present invention is implemented as follows: a positioning and clamping fixture for assembling chain plates includes a base and a positioning component installed on the base.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5 This utility model provides a positioning and clamping fixture for assembling chain plates, including a base 1 and a positioning component 2 installed on the base 1. The positioning component 2 is used to place the chain plate 4. The base 1 is also equipped with a clamping component 3 for clamping the chain plate 4 onto the positioning component 2.

[0032] The positioning component 2 includes:

[0033] Mounting base 21, wherein a movable groove 22 is provided in the mounting base 21;

[0034] The first positioning unit 23 is installed in the movable slot 22 and includes:

[0035] A bidirectional lead screw 232 is rotatably mounted at both ends on the inner walls of both sides of the movable groove 22, and the middle part of the bidirectional lead screw 232 passes through the center plate 231 set in the middle of the movable groove 22.

[0036] The adjusting seat 233 is slidably set in the movable groove 22, symmetrically located on both sides of the center plate 231, and threadedly engaged with the bidirectional lead screw 232. A retainer 234 is installed on the adjusting seat 233 by bolts 235. The top protrusion of the retainer 234 is adapted to the pre-set tooth groove 41 at the bottom of the chain plate 4.

[0037] In practical application, the operator first rotates the bidirectional lead screw 232 according to the specifications of the chain plate 4 to be assembled, driving the two adjusting seats 233 to slide relative to or away from each other along the movable groove 22, thereby adjusting the distance between the two retaining seats 234 so that the protrusion on the top of the retaining seat 234 corresponds to the tooth groove 41 on the bottom of the chain plate 4. Then, the chain plate 4 is placed on the retaining seat 234, so that the tooth groove 41 and the protrusion are accurately engaged, achieving the initial positioning of the chain plate 4. Finally, the chain plate 4 is pressed and fixed by the clamping assembly 3 to facilitate the subsequent pin assembly operation.

[0038] In this embodiment, the protrusion on the top of the card holder 234 engages with the tooth groove 41 at the bottom of the chain plate 4. In conjunction with the bidirectional lead screw 232, the two adjusting seats 233 move synchronously relative to each other or apart. This allows for quick adjustment of the distance between the two card holders 234, thereby adapting to the tooth groove 41 positions of chain plates 4 of different specifications. This improves the versatility of the tooling, facilitates precise positioning of the chain plate 4, and effectively prevents the chain plate 4 from shifting during the pressing process, ensuring the positional accuracy of the subsequent pin assembly.

[0039] Please see Figure 4 In a preferred embodiment of the present invention, guide blocks 2331 are provided on both sides of the adjusting seat 233, and guide grooves 221 adapted to the size of guide blocks 2331 are provided on both sides of the movable groove 22 at the positions corresponding to the guide blocks 2331. The guide blocks 2331 are slidably disposed in the guide grooves 221.

[0040] In this embodiment, the guide block 2331 and the guide groove 221 form a sliding pair, which provides a stable guiding effect for the movement of the adjusting seat 233. This ensures that the adjusting seat 233 can slide smoothly along the axis of the bidirectional lead screw 232 under the drive of the bidirectional lead screw 232, avoiding swaying or jamming. This ensures the symmetry of the two card seats 234, so that when the specifications of the two chain plates 4 are changed, the pin hole position is still in the middle position, further improving the positioning accuracy of the chain plate 4, and thus facilitating the subsequent pin assembly operation.

[0041] Please see Figures 1 to 3 In another preferred embodiment of this utility model, the mounting base 21 is further provided with a second movable groove 24, and a second positioning unit 25 is installed in the second movable groove 24. The second positioning unit 25 includes:

[0042] The adjusting rod 251 has its two ends rotatably mounted on the inner walls of both sides of the movable groove 24, and the axis of the adjusting rod 251 is perpendicular to the axis of the bidirectional lead screw 232;

[0043] The positioning seat 252 is slidably disposed in the movable groove 24 and threadedly engaged with the adjusting rod 251. The top of the positioning seat 252 is provided with a limiting plate 2521, which is attached to one end of the chain plate 4.

[0044] Furthermore, the second positioning unit 25 also includes a guide rail 253, which is installed in the movable groove 24 and is parallel to the axis of the adjusting rod 251. The bottom of the positioning seat 252 is provided with a guide groove 2522 that is adapted to the size of the guide rail 253 at the position corresponding to the guide rail 253.

[0045] In this embodiment, by setting up a second positioning unit 25, the operator can rotate the adjusting rod 251 to drive the positioning seat 252 to slide along the second movable groove 24, thereby adjusting the position of the limiting plate 2521 so that the limiting plate 2521 is in contact with one end of the chain plate 4, limiting the chain plate 4 in the length direction. Working in conjunction with the first positioning unit 23, this achieves multi-directional positioning of the chain plate 4, further improving the positional certainty of the chain plate 4 on the tooling. The guide rail 253 cooperates with the second guide groove 2522 to provide guidance and support for the sliding of the positioning seat 252, ensuring the smoothness of the adjustment process.

[0046] Please see Figure 4 and Figure 5 In another preferred embodiment of the present invention, the top of the adjusting seat 233 is provided with a plurality of positioning posts 2332, and the bottom of the card seat 234 is provided with a plurality of positioning holes 2341 of the same size as the positioning posts 2332 at the positions corresponding to the positioning posts 2332. The positioning holes 2341 are inserted into the positioning posts 2332.

[0047] This embodiment achieves rapid and accurate installation and positioning by setting a positioning post 2332 on the top of the adjusting seat 233 and opening a positioning hole 2341 at the bottom of the clamping seat 234. The clamping seat 234 is inserted into the positioning post 2332 through the positioning hole 2341, and finally locked with bolts 235 to ensure the connection strength between the clamping seat 234 and the adjusting seat 233. Furthermore, the modular design of the adjusting seat 233 and the clamping seat 234 facilitates quick replacement of the corresponding clamping seat 234 according to different models of chain plates 4, thereby further improving the versatility and maintenance convenience of the tooling.

[0048] Please see Figure 2 In another preferred embodiment of this utility model, the clamping component 3 includes:

[0049] Multiple mounting brackets 31 are mounted on the upper surface of the base 1, and the same crossbeam 32 is horizontally mounted on the top of each mounting bracket 31;

[0050] The telescopic cylinder 33 is installed on the top of the crossbeam 32, and its telescopic end passes through the crossbeam 32 and extends to the bottom of the crossbeam 32 to be fixedly connected to the pressure plate 34.

[0051] Furthermore, a pad 35 is also installed at the bottom of the pressure plate 34. The pad 35 is made of elastic material. The pad 35 drives the pressure plate 34 through the telescopic cylinder 33, thereby squeezing the upper surface of the chain plate 4.

[0052] In this embodiment, the pressure plate 34 is moved up and down by the telescopic cylinder 33. After the chain plate 4 is placed and positioned, the telescopic cylinder 33 extends, driving the pressure plate 34 to move downward, so that the pad 35 presses against the upper surface of the chain plate 4. The pad 35 is made of elastic material, which can play a buffering role during the pressing process, thereby avoiding rigid impact between the pressure plate 34 and the chain plate 4, preventing the surface of the chain plate 4 from being crushed or indented. At the same time, the elastic pad 35 can adapt to any slight unevenness that may exist on the surface of the chain plate 4, achieving uniform pressing and ensuring the stability of the chain plate 4 during the pressing process.
