Abstract
Description
Technical Field
[0001] This utility model specifically relates to a chain assembly / disassembly mold. Background Technology
[0002] Chains are generally metal links or rings, and are mostly used for mechanical transmission and traction. Most existing chains are composed of components such as chain plates, chain pins, and bushings. Therefore, during the assembly process, the bushings need to be put onto the chain pins, and then the chain plates are assembled with the chain pins by snap-fit.
[0003] Traditional chain assembly is done manually, which reduces work efficiency and increases the workload for workers. Chain assembly molds are needed to assist in production. Utility Model Content
[0004] The purpose of this invention is to provide a chain assembly / disassembly mold to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a chain assembly / disassembly mold, comprising a base plate, a gear centrally located on the lower surface of the base plate, and a first rack and a second rack meshing on both sides of the gear respectively; a rod extending downward from the end of the first rack and the second rack away from the gear; the two rods are respectively inserted into the head and tail chain holes of the chain, and then the gear is rotated to make the first rack and the second rack move synchronously towards each other, thereby pulling the head and tail of the chain closer together and completing the splicing.
[0006] Preferably, the lower surface of the substrate is provided with two fixing strips, the fixing strips are provided with slide rails, and the slide rails are provided with rollers.
[0007] Preferably, the roller is connected to the first rack and the second rack via a connecting rod.
[0008] Preferably, the fixing strip is provided with a baffle extending inward from the groove edge of the slide rail.
[0009] Preferably, a motor is disposed on the upper surface of the substrate, and a fixing rod is connected to the power output end of the motor.
[0010] Preferably, the fixing rod is inserted into the gear through the base plate.
[0011] Preferably, there are four rollers, with two rollers on each of the first and second racks.
[0012] The technical effects and advantages of this utility model are as follows: This chain assembly and disassembly mold involves inserting the insert rods into the first and last chain holes of the chain, starting the motor, and driving the fixed rod to rotate, which in turn drives the gear to rotate. Since the gear meshes with the first and second racks, the roller slides along the length of the slide rail, causing the first and second racks to move closer together, which in turn drives the first and last ends of the chain to move closer together. As the first and last ends of the chain move closer together, they are then inserted into the chain pins of the chain plate, thus achieving chain splicing. The overall structure is simple and improves the efficiency of chain splicing. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] For easier chain assembly, please refer to... Figure 1 , Figure 2 and Figure 3As shown, the system includes a base plate 1. A gear 2 is centrally located on the lower surface of the base plate 1. A first rack 3 and a second rack 4 mesh with each other on both sides of the gear 2. A rod 5 extends downward from the end of the first rack 3 and the second rack 4 away from the gear 2. The two rods 5 are inserted into the head and tail chain holes of the chain, respectively. Then, the gear 2 is rotated, causing the first rack 3 and the second rack 4 to move synchronously towards each other, thereby bringing the head and tail of the chain closer together and completing the splicing. By inserting the rods 5 into the head and tail chain holes of the chain, the motor 11 is started. The power output end of the motor 11 drives the fixed rod 12 to rotate, which in turn drives the gear 2 to rotate. Since the gear 2 meshes with the first rack 3 and the second rack 4, the roller 8 slides along the length of the slide rail 7, bringing the first rack 3 and the second rack 4 closer together, causing the head and tail of the chain to move closer together. As the head and tail of the chain move closer together, they are inserted into the chain pins of the chain plate, realizing the splicing of the chain. The overall structure is simple.
[0017] To facilitate driving the first rack 3 and the second rack 4 closer together, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the lower surface of the substrate 1 is provided with two fixing strips 6, and a slide rail 7 is provided inside the fixing strip 6. A roller 8 is provided inside the slide rail 7. As the roller 8 slides along the length of the slide rail 7, it drives the first rack 3 and the second rack 4 to move, allowing the first rack 3 to move closer or further apart. The roller 8 is connected to the first rack 3 and the second rack 4 via a connecting rod 9. The connecting rod 9 allows the roller 8 to drive the first rack 3 and the second rack 4 to move along with it. A baffle 10 extends inward from the groove edge of the fixing strip 6 toward the slide rail 7, blocking the slide rail 7 and preventing the roller 8 from falling out of the slide rail 7. A motor 11 is provided on the upper surface of the substrate 1. The power output end of the motor 11 is connected to a fixing rod 12. The motor 11 drives the fixing rod 12 to rotate, which in turn drives the gear 2 to rotate. A through hole is provided on the surface of the substrate 1 for the fixing rod 12 to pass through. The fixing rod 12 passes through the base plate 1 and is inserted into the gear 2. As the fixing rod 12 rotates, it can drive the gear 2 to rotate as well. There are four rollers 8, with two rollers 8 respectively on the first rack 3 and the second rack 4.
[0018] In use, first insert the plug rod 5 into the first and last chain holes of the chain respectively, start the motor 11, the power output end of the motor 11 drives the fixed rod 12 to rotate, which drives the gear 2 to rotate. Since the gear 2 meshes with the first rack 3 and the second rack 4, the roller 8 slides in the slide rail 7 along the length of the slide rail 7, so that the first rack 3 and the second rack 4 move closer to each other, which drives the first and last ends of the chain to move closer to each other. After the first and last ends of the chain move closer to each other, they are inserted into the chain pins of the chain plate to realize the splicing of the chain.
[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
