Description

Technical Field

[0001] This utility model relates to the technical field of industrial chain manufacturing and maintenance, and in particular to the technical field of a chain installation tool adapted to multi-specification jacks. Background Technology

[0002] In industrial chain assembly and maintenance, jacks provide lifting force for processes such as chain plate pressing and pin pin pressing. However, the connection structure between the back plate and the jack of traditional chain installation tools is fixed, and they can only be adapted to jacks of specific specifications (such as fixed tonnage and shape). When the chain specifications change (large pitch requires large tonnage jacks, and small pitch requires small tonnage jacks), the tools are incompatible. This easily leads to the problem of power matching, which wastes resources when large tonnage jacks are used to produce small pitch chains, and seriously restricts the flexibility and versatility of operations. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art and to propose a chain installation tool that is compatible with multiple specifications of jacks, so as to achieve flexible compatibility with multiple specifications of jacks and improve the flexibility and versatility of operation.

[0004] To achieve the above objectives, this utility model proposes a chain installation tool adaptable to jacks of various specifications, including a front baffle, a rear baffle, two clamping mechanisms, several connecting rods, a jack, and a slide. The two ends of the connecting rods pass through the front and rear baffles respectively. Each connecting rod has a threaded fixing nut on both sides of the front and rear baffles. The clamping mechanisms are symmetrically arranged on the inner side of the front baffle. A jack is clamped and fixed between the two clamping mechanisms. The slide is slidably mounted on at least two of the connecting rods. The piston rod of the jack is detachably connected to the slide. Each clamping mechanism includes a chuck and a clamping groove at the clamping end of the chuck. The two chucks move towards each other to clamp the jack and move in opposite directions to release the jack.

[0005] Preferably, the clamping mechanism further includes a support, a threaded rod, a tightening head, a locking nut, and two guide rods. The support is provided with a slidable guide rod and a threaded rod that is threaded together. The inner end of the guide rod is provided with a chuck. The inner end of the threaded rod is rotatably connected to the chuck. The outer end of the threaded rod is provided with a tightening head. The threaded rod is provided with a locking nut on the outside of the support.

[0006] Preferably, the clamping groove is a V-shaped groove.

[0007] Preferably, the rear end of the slide is provided with a top head, and the rear baffle is provided with a clearance hole corresponding to the top head.

[0008] Preferably, the front end of the jack is provided with a screw section, the rear end of the piston rod of the jack is provided with a threaded hole that mates with the screw section, the screw section passes through the through hole on the slide and is threadedly connected to the threaded hole, and the front peripheral surface of the jack is provided with a turning part, the cross-section of the turning part is a regular polygon shape.

Detailed Implementation

[0015] See Figure 1 , Figure 2 and Figure 3This utility model discloses a chain installation tool adaptable to jacks of various specifications, including a front baffle 1, a rear baffle 2, two clamping mechanisms 3, several connecting rods 4, a jack 5, and a slide 6. The two ends of the connecting rods 4 pass through the front baffle 1 and the rear baffle 2 respectively. The connecting rods 4 are provided with threaded fixing nuts 7 on both sides of the front baffle 1 and the rear baffle 2. The clamping mechanisms 3 are symmetrically arranged on the inner side of the front baffle 1. The jack 5 is clamped and fixed between the two clamping mechanisms 3. The slide 6 is slidably disposed on at least two of the connecting rods 4. The piston rod of the jack 5 is detachably connected to the slide 6. The clamping mechanism 3 includes a chuck 31 and a clamping groove 32 provided on the clamping end of the chuck 31. The two chucks 31 move towards each other to clamp the jack 5 and move in opposite directions to release the jack 5.

[0016] The clamping mechanism 3 further includes a support 33, a threaded rod 34, a tightening head 35, a locking nut 36, and two guide rods 37. The support 33 is provided with a slidable guide rod 37 and a threaded rod 34. The inner end of the guide rod 37 is provided with a chuck 31. The inner end of the threaded rod 34 is rotatably connected to the chuck 31. The outer end of the threaded rod 34 is provided with a tightening head 35. The threaded rod 34 is provided with a locking nut 36 on the outside of the support 33.

[0017] The clamping groove 32 is a V-shaped groove.

[0018] The rear end of the slide block 6 is provided with a top head 16, and the rear baffle 2 is provided with a clearance hole 8 corresponding to the top head 16.

[0019] The front end of the top head 16 is provided with a screw section 9, and the rear end of the piston rod of the jack 5 is provided with a threaded hole 10 that mates with the screw section 9. The screw section 9 passes through the through hole 13 on the slide block 6 and is threadedly connected to the threaded hole 10. The front peripheral surface of the top head 16 is provided with a turning part 11, and the cross-section of the turning part 11 is a regular polygon shape.

[0020] The jack 5 is equipped with a clamp 14, and the clamp 14 is equipped with a handle 15.

[0021] The slide block 6 is slidably mounted on the two upper connecting rods 4, and a linear bearing 12 is provided between the slide block 6 and the two upper connecting rods 4.

[0022] The working process of this utility model: This utility model discloses a chain installation tool adapted to multiple specifications of jacks. During operation, when it is necessary to replace the jack 5, the wrench is used to turn the turning part 11. The turning part 11 drives the screw section 9 to rotate through the top head 16, causing the screw section 9 to disengage from the threaded hole 10. Then, the locking nut 36 is loosened, and the turning head 35 is turned counterclockwise to drive the threaded rod 34 to rotate. At the same time, the rotation of the threaded rod 34 drives the chuck 31 to release its grip on the jack 5, and then the jack 5 can be disassembled. Then, the required jack 5 is placed between the two chucks 31. Then, the screw section 9 of the top head 16 is threaded through the through hole 13 and connected to the threaded hole 10 on the jack 5. Then, the turning head 35 is turned clockwise to drive the threaded rod 34 to rotate. At the same time, the rotation of the threaded rod 34 drives the chuck 31 to grip the jack 5. After the jack 5 is clamped and fixed, the locking nut 36 is tightened.

[0023] The clamping frame, composed of parts such as front baffle 1, rear baffle 2, connecting rod 4, and fixing nut 7, can be adapted to different specifications of chains by adjusting the fixing nuts 7 at both ends of the connecting rod.

[0024] The clamp 14 is equipped with a handle 15, which makes it easy to pick up the jack 5.

[0025] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
