Description

Technical Field

[0001] This utility model belongs to the field of chain plate assembly technology, and specifically relates to a chain plate assembly tooling. Background Technology

[0002] With the development of the machine tool industry, chain conveyor chip conveyors are widely used as key components. Currently, chain assembly mostly relies on manual operation or step-by-step control by automated equipment, which presents the following problems: manual assembly requires piecing together and hammering, which not only generates noise but also results in low work efficiency; some automated equipment is used for assembly, with each component controlled by a control device to start and stop. Because the control device needs a certain reaction time after each step to control the next step, the assembly efficiency of the chain is low.

[0003] To address the problem of low assembly efficiency, Chinese patent CN116276039A discloses an automatic assembly device for chain plates. Although the assembly time is reduced by linkage with a power cylinder, the pin feeding unit relies on the precise matching of the loading groove and receiving groove of the rotating column. If the pin has dimensional deviation or deformation, it is easy to cause jamming or poor unloading, which affects the assembly efficiency.

[0004] Therefore, there is an urgent need for a more reliable chain plate assembly tooling to solve the problems of low efficiency in manual assembly and material jamming or poor material feeding in automated equipment, thereby improving overall assembly efficiency. Utility Model Content

[0006] The technical solution adopted by this utility model is as follows: a chain plate assembly fixture, including a workbench and a chain plate storage box, wherein the workbench is provided with a cold drawing roller feeding mechanism and an assembly mechanism, the cold drawing roller feeding mechanism is provided with an inclined roller track and a material drop groove, and the assembly mechanism includes:

[0007] First cylinder: pushes the lowest first chain plate of the chain plate storage box out to engage with the second chain plate below the clamping block;

[0008] Clamping cylinder: pushes the clamping block to press the meshing point of the first chain plate and the second chain plate;

[0009] Second cylinder: Push the cold-drawn roller from the feed chute into the chain plate mounting hole to complete the assembly.

[0014] Preferably, elastic buffer strips are provided on both sides of the guide groove.

[0015] Preferably, the contact surface between the clamping block and the chain plate is provided with a positioning groove that fits the edge contour of the chain plate.

[0016] Preferably, the output end of the second cylinder has a pusher that fits the profile of the end of the cold-drawn rod.

[0017] Preferably, a chain plate assembly fixture further includes a control system, including a programmable logic controller (PLC) and a position sensor. The position sensor is used to detect the position of the chain plate and the cold drawing roller.

[0047] Example 1:

[0048] A preferred embodiment, such as Figure 1-11As shown, a chain plate assembly fixture workbench 1 includes a chain plate storage box 2, a cold-drawn roller feeding mechanism 3, and an assembly mechanism 4 for assembling chain plates and cold-drawn rollers 5. For cold-drawn rollers 5 of different specifications, the workbench 1 is equipped with a protective frame 11, which has a slide groove 111. An adjusting plate 311 is provided on one side of the inclined roller track 31. The adjusting plate is fixed between the protective frame and the inclined roller track 31 by bolts 112. By adjusting the position of the bolts 112 in the slide groove 111, it can be adapted to the size of the cold-drawn roller 5. For chain plates of different specifications, the chain plate storage box 2 is equipped with a chain plate baffle 25. The side wall of the chain plate storage box 2 is provided with a round hole 26. The chain plate baffle 25 is provided with a cylinder 251 that mates with the round hole 26. By changing the length of the cylinder 251 extending into the round hole 26, it can accommodate chain plates of different specifications. In addition, the side wall of the chain plate baffle 25 is provided with a guide groove 23, and elastic buffer strips 231 are attached to both sides of the guide groove 23. The elastic buffer strips 231 on both sides of the guide groove 23 of the chain plate baffle effectively reduce the collision damage during the falling of the chain plate. When the assembly work starts, multiple chain plates are placed into the chain plate storage box 2, so that the bottom first chain plate 21 is in the ready-to-push state; the clamping cylinder 43 pushes the clamping block 44, and the clamping block 44 has a positioning groove 441 on the contact surface with the chain plate that fits the edge contour of the chain plate, to clamp the second chain plate 23. The clamping cylinder 43 clamps the first chain plate 22 and the second chain plate at the meshing point to ensure that the chain plate will not move during the assembly process. The first cylinder 41 is activated to push the first chain plate 22 out to mesh with the second chain plate 23 below the clamping block 44. The cold-drawn roller 5 is placed on the inclined roller track 31 of the cold-drawn roller feeding mechanism 3. The design of the inclined roller track 31 ensures that the cold-drawn roller 5 can roll smoothly on the inclined roller track 31 and pass through the material drop groove 32 under the action of gravity, reducing the reliance on power. The structure of the slide groove 111 and bolt 112 adapts to the feeding requirements of cold-drawn rollers 5 of different specifications, avoiding material jamming caused by specification differences. A magnetic block 321 that matches the curvature of the cold-drawn roller 5 is set at the material drop groove 32. The magnetic block 321 at the material drop groove 32 assists in the precise positioning of the cold-drawn roller 5, ensuring the accuracy of cold-drawn roller feeding. The output end of the second cylinder 42 has a pusher 421 that fits the end contour of the cold-drawn roller 5. When the second cylinder 42 is activated, it pushes the cold-drawn roller 5 from the material drop groove 32 into the chain plate mounting hole 24, completing the assembly of the chain plate and the cold-drawn roller 5.

[0049] Example 2:

[0050] like Figure 1-11As shown, a chain plate assembly fixture, different from Embodiment 1, has a protective frame 11 installed on the workbench 1. The programmable logic controller (PLC) 61 of the control system 6 is installed on the side of the workbench 1, and the position sensor 62 is installed at the core of the assembly mechanism. The control system 6 is connected to each cylinder and sensor. After the position sensor 62 detects that the first chain plate 21, the second chain plate 22, and the cold-drawn roller 5 are in the appropriate position, it feeds back the signal to the PLC 61. The PLC 61 controls the first cylinder 41 to move, pushing the bottom first chain plate 21 of the chain plate storage box 2 to engage with the second chain plate 22 below the clamping block 44. Then, the clamping cylinder 43 pushes the clamping block 44 to press the engagement point of the first chain plate 21 and the second chain plate 22. Finally, the second cylinder 42 pushes the cold-drawn roller 5 from the drop chute 32 into the chain plate mounting hole 24 to complete the assembly and enter the next cycle. The programmable controller 61 precisely controls the action sequence and stroke of the first cylinder 41, the clamping cylinder 43 and the second cylinder 42 based on the position signals of the chain plate and the cold drawing roller fed back by the position sensor 62, so as to ensure that the entire assembly process is accurate, efficient and stable.
