Description

Technical Field

[0001] This utility model relates to a disassembly device, and more particularly to a chain disassembly device. Background Technology

[0002] In industrial production and machinery maintenance, chain disassembly is frequently required. Traditional chain disassembly methods often involve striking the chain pins with a hammer, which has several drawbacks. Firstly, it's difficult to precisely control the force when using a hammer, easily damaging the chain and affecting its subsequent performance, even rendering it unusable. Secondly, there are significant safety hazards during the striking process, such as a chain pin suddenly flying out and potentially injuring the operator. Furthermore, existing disassembly tools are often only suitable for specific chain models and specifications. For work scenarios involving multiple chain models, multiple different disassembly tools are required, making the operation cumbersome and inefficient. Therefore, developing a safe, efficient disassembly device applicable to multiple chain models is of significant practical importance. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a chain disassembly device that can achieve precise positioning, clamping and efficient disassembly of chains of various sizes, thereby improving disassembly efficiency and eliminating safety hazards.

[0004] This utility model is achieved through the following technical solution:

[0005] A chain disassembly device includes a flexible clamping mechanism and a disassembly mechanism;

[0006] The flexible clamping mechanism includes two sets of flexible clamping components arranged opposite each other on the left and right. The side opposite to the two sets of flexible clamping components is the inner side. Each set of flexible clamping components includes a clamping seat and multiple clamping bars elastically arranged inside the clamping seat. Each clamping bar can elastically extend and retract along the left and right direction of the clamping seat. The chain is elastically clamped by the multiple clamping bars inside the two sets of flexible clamping components. The driving component drives the clamping seats of the two sets of flexible clamping components to move closer to each other or further away from each other.

[0007] The disassembly mechanism includes a disassembly support plate, with a vertically extending ejector screw threaded to the middle section of the disassembly support plate. The bottom of the ejector screw extends downward below the disassembly support plate. Rotating the ejector screw downward pushes the chain pin downward through the bottom end of the ejector screw.

[0008] As a preferred embodiment of the above-mentioned chain disassembly device, the drive assembly includes two lead screws, left and right, which are coaxially connected by a coupling. The two lead screws rotate in opposite directions. The clamping seats of the two sets of flexible clamping assemblies have threaded holes, and the two lead screws are threadedly engaged with the threaded holes on the two clamping seats respectively.

[0009] As a preferred embodiment of the above-mentioned chain disassembly device, the outer ends of the two lead screws extend beyond the two clamping seats, and one of the lead screws has a lead screw handle perpendicular to the lead screw.

[0010] As a preferred embodiment of the above-mentioned chain disassembly device, it also includes a mounting base, which includes a mounting base plate and covers fixed to the left and right ends of the mounting base plate. Each clamping seat has outwardly protruding sliding protrusions on the front and rear sides of its bottom.

[0014] This invention has the following advantages over the prior art:

[0015] This utility model provides a chain disassembly device. Its flexible clamping mechanism achieves stable, precise, and centered clamping of the chain through two sets of flexible clamping components, and can adapt to the clamping of chains of different sizes. It eliminates the need to prepare different disassembly devices for different chain sizes, reducing costs and improving the versatility of the equipment. Its disassembly mechanism can push out the chain pin of the precisely clamped chain by rotating the ejector screw. The whole process is convenient to operate, greatly shortening the chain disassembly time and improving work efficiency.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0022] See Figures 1 to 4 This embodiment discloses a chain disassembly device, including a flexible clamping mechanism and a disassembly mechanism. The flexible clamping mechanism includes two sets of flexible clamping components arranged opposite each other, with the opposite side of the two sets of flexible clamping components being the inner side. Each set of flexible clamping components includes a clamping seat 1 and multiple clamping rods 2 elastically arranged inside the clamping seat 1. Each clamping rod 2 can elastically extend and retract along the left and right direction of the clamping seat 1. The clamping seat 1 has multiple mounting holes on its inner side, and the multiple clamping rods 2 are correspondingly arranged in the multiple mounting holes. Each clamping rod 2 is elastically connected to the clamping seat 1 by a spring. The multiple clamping rods 2 inside the two sets of flexible clamping components achieve elastic clamping of the chain. The driving component drives the clamping seats 1 of the two sets of flexible clamping components to move closer or further apart. The drive assembly includes two lead screws 3, one on the left and one on the right, which are coaxially connected by a coupling 4. The two lead screws 3 rotate in opposite directions. The clamping seats 1 of the two sets of flexible clamping assemblies have threaded holes, and the two lead screws 3 are threaded into the threaded holes on the two clamping seats 1 respectively. The outer ends of the two lead screws 3 extend beyond the two clamping seats 1 respectively, and one of the lead screws 3 has a lead screw handle 5 perpendicular to the lead screw 3 at its outer end. Specifically, a radially through hole can be opened at the outer end of one of the lead screws 3. The lead screw handle 5 includes a lead screw handle 5 rod and ball heads threaded to both ends of the lead screw handle 5 rod. During installation, the lead screw handle 5 rod is inserted into the through hole of the lead screw 3, and then the ball heads are screwed onto both ends of the lead screw handle 5 rod.

[0023] The disassembly mechanism includes a disassembly support plate 6. A vertically extending ejector screw 7 is threadedly connected to the middle section of the disassembly support plate 6. The bottom of the ejector screw 7 extends downwards below the disassembly support plate 6. Rotating the ejector screw 7 downwards pushes the chain pin downwards through its bottom end. The bottom end of the ejector screw 7 has an ejector end 8, the diameter of which is smaller than the diameter of the rod portion of the ejector screw 7. The ejector screw 7 pushes the chain pin downwards through the ejector end 8. The upper end of the ejector screw 7 has a disassembly handle 9 perpendicular to it. Specifically, an extension rod 10 can be welded to the upper end of the head of the ejector screw 7. A radially penetrating through hole is formed in the extension rod 10. The disassembly handle 9 is installed on the extension rod 10 in the same way as the lead screw handle 5 is installed on the lead screw 3.

[0024] The chain disassembly device also includes a mounting base, which includes a mounting base plate 11 and a cover 12 fixed to the left and right ends of the mounting base plate 11. Each clamping seat 1 has outwardly protruding sliding protrusions 13 on the front and rear sides of its bottom. The mounting base plate 11 has sliding grooves 14 on the front and rear sides of its front and rear sides for the sliding protrusions 13 on the front and rear sides of the clamping seat 1 to slide in the left and right direction. The disassembly support plate 6 is fixedly installed on the top of the two covers 12 at its left and right ends.

[0025] In use, place the mounting base of the chain disassembly device on a stable workbench. Place the chain to be disassembled between the two clamping seats 1, so that the chain pins connecting adjacent chain links are arranged vertically, and the chain pin to be disassembled is located below the ejector screw 7. The operator turns the lead screw handle 5, causing the two lead screws 3 to rotate. Since the threads on the two lead screws 3 rotate in opposite directions, the two clamping seats 1 that are threaded with the two lead screws 3 move closer to each other. The multiple clamping rods 2 inside the two clamping seats 1 clamp the chain from the left and right sides respectively. Since each clamping rod 2 can elastically extend and retract, the multiple clamping rods 2 will adaptively adjust according to the shape of different parts of the chain. In the gaps of the chain, the corresponding clamping rod 2 will be inserted into the gaps of the chain. Therefore, this flexible clamping mechanism can clamp the chain from the left and right, up and down, and front and back directions in multiple directions, ensuring that the clamped chain is in a stable and centered position, thereby ensuring the centered clamping of the chain pin, so that the chain pin to be disassembled is located directly below the ejector screw 7 of the disassembly mechanism.

[0026] After the chain is positioned and clamped, the operator rotates the disassembly handle 9, causing the ejector screw 7 to rotate. Due to the elongated design of the head of the ejector screw 7 and the cooperation of the disassembly handle 9, the operator can easily apply a large torque. As the ejector screw 7 moves downward, its lower ejector end 8 gradually contacts and presses down on the chain pin. Since the chain has been precisely positioned in the center beforehand, the ejector end 8 of the ejector screw 7 can be precisely coaxial with the chain pin, thus smoothly ejecting the chain pin.

[0027] After removing the chain pins, rotate the disassembly handle 9 in the opposite direction to move the ejector screw 7 upwards and disengage it from the chain; then rotate the lead screw handle 5 in the opposite direction to move the two sets of flexible clamping components away from each other, releasing the chain. This completes the convenient, time-saving, labor-saving, safe, and non-destructive disassembly of the chain.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
