Abstract
The utility model provides a disassembly tool of drive chain, which is composed of a fixed base, a changeable bush, an ejector pin and a screw. The fixed base is concave. The changeable bush in which the middle is provided with a hole is installed on the front end of the fixed base. The screw and the back end of the fixed base are connected through the thread. The centreline of the changeable bush is in the same axis with the screw centreline. The ejector pin is installed on the front end of the screw. When in use, the fixed base is caught in the bench clamp, and the chain is disposed between the changeable bush and the ejector pin. The rotation rod is rotated to drive the screw to move forward so that the chain pin can be pushed out from the centre hole of the changeable bush by the ejector pin. Thus the chain can be disassembled. The changeable bushes with different apertures and the ejector pins with different diameters can be replaced to adapt to the disassembly of the chains with different specifications. With the simple structure, easy and safe usage, the utility model is able to be adapted to the disassembly of the chains with different specifications.
Description
Technical field
The utility model relates to the extracting tool of driving chain.
Background technology
Driving chain generally adopts bushroller chain, be made up of inner plate, outer plate, bearing pin, sleeve and roller, bearing pin and outer plate, sleeve and inner plate are fixed with interference fit respectively, connect by outer plate between each chain link, when chain link bent and stretched, sleeve can freely rotate on bearing pin.When needs block chain, need bearing pin is extruded the outer plate that removes both sides.The practice of dismounting chain sweeps away bearing pin with hand hammer and punching pin normally by bench vice or parallels at present, and operation inconvenience is wasted time and energy, and efficient is low.The patent No. provides a kind of " chain extracting tool " that can effectively improve removal efficiency for the Chinese patent of CN01276802.2, and its structure is the middle part that a push rod passes crossbeam, and the push rod upper end is provided with swing handle, and the lower end is provided with top, and a nut is screwed onto the push rod bottom; The torque arm that respectively is coupling of the two ends of crossbeam, the connector that is coupling between the other end of torque arm and the nut, the torque arm inboard is provided with gib head.Though this patent can effectively improve removal efficiency, complex structure can only be applicable to the chain dismounting of single specification.And the torque arm inboard is provided with gib head, has certain risk during dismounting, scratches hand easily.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use at the deficiencies in the prior art, adapts to the driving chain stripping attachment of different size chain dismounting.
For achieving the above object, the utility model adopts following technical solution:
The driving chain stripping attachment is made up of holder, slip bushing, push rod and screw rod, holder is matrix, the front end that is installed in holder with holes in the middle of the slip bushing, the rear end of screw rod and holder is for being threaded, the center line of slip bushing and the center line of screw rod are positioned on the same axis, and push rod is installed in the front end of screw rod.The rearward end of screw rod is equipped with bull stick.
During use, holder is clipped on the bench vice, chain is placed between slip bushing and the push rod.Rotate bull stick screw rod is moved forward, push rod can eject chain hinge pin from the interstitial hole of slip bushing, thereby chain is taken apart.The push rod that can change the slip bushing in different apertures and different-diameter adapts to the dismounting of different size chain.
The utility model is simple in structure, and is easy to use, safe, can adapt to the dismounting of different size chain.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, slip bushing, 2, holder, 3, push rod, 4, screw rod, 5, bull stick.
The specific embodiment:
Embodiment:
Accompanying drawing has provided structural representation of the present utility model.This driving chain stripping attachment is by holder 2, slip bushing 1, push rod 3 and screw rod 4 are formed, holder 2 is matrix, with holes in the middle of the slip bushing 1, be installed in the front end of holder 2, the rear end of screw rod 4 and holder 2 is for being threaded, the center line of slip bushing 1 and screw rod 4 center line be positioned on the same axis, push rod 3 is installed in the front end of screw rod 4, and the rearward end of screw rod 4 is equipped with bull stick 5, and the diameter of push rod 3 is less than the diameter of chain hinge pin.During use, holder 2 is clipped on the bench vice, chain is placed between slip bushing 1 and the push rod 3.Rotate bull stick 5 screw rod 4 is moved forward, push rod 3 roof pressures that make screw rod 4 front ends are rotated further bull stick 5 on the bearing pin of chain, and push rod 3 can eject chain hinge pin from the interstitial hole of slip bushing 1, thereby chain is taken apart.The specification difference of chain, the diameter of its bearing pin are also different, and the push rod that the utility model can be changed the slip bushing in different apertures and different-diameter adapts to the chain of different size.
Claims (2)
1. driving chain stripping attachment, form by holder, slip bushing, push rod and screw rod, it is characterized in that: holder is matrix, the front end that is installed in holder with holes in the middle of the slip bushing, the rear end of screw rod and holder is for being threaded, the center line of slip bushing and the center line of screw rod are positioned on the same axis, and push rod is installed in the front end of screw rod.
