Description

Positioning chain dismounting device

Technical Field

The utility model relates to a disassembling tool, in particular to a positioning chain disassembling device.

Background

The chain transmission has the advantages of being capable of working in severe environments with greasy dirt and high temperature, and therefore being widely used in transmission links of factories. However, due to long-term use, hinge abrasion may occur in the chain, so that the pitch becomes large, and the chain is disconnected, so that the overhaul work of the chain is also particularly important.

When the chain is disassembled, the pin shafts among the chain links need to be disassembled, and the traditional disassembling mode is as follows: the bench clamp is used for clamping and fixing the column chain, then the vice is used for clamping a thimble, the thimble is aligned to a pin shaft of the chain, and the pin shaft is knocked out by vertically knocking the thimble. The disassembly mode has the advantages that the hammer can injure hands in the operation process, the thimble can fly out without clamping, potential safety hazards exist, and the disassembly process is time-consuming and labor-consuming.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provides a positioning chain detacher so as to realize convenient and quick detachment of a chain pin shaft.

The utility model is realized by the following technical scheme:

the utility model provides a location chain ware of unpick, includes the base, fixed block and the cushion that the interval was arranged about being equipped with on the base, open threaded hole on the fixed block, threaded connection has the silk cover in the threaded hole of fixed block, presss from both sides the upper and lower both ends of tight chain through silk cover bottom and cushion top, and the silk cover center is opened there is the centre bore, and the thimble includes thimble head and thimble pole portion, and the centre bore of silk cover is passed down from last to thimble pole portion, opens the blanking hole that supplies the round pin axle whereabouts of chain on the cushion, and thimble pole portion and blanking hole are coaxial.

Further, fixed block and cushion one side link together through a curb plate, and fixed block, cushion and curb plate form a C font holder, are equipped with the stand on the base, and the holder passes through curb plate fixed mounting on the stand.

Further, the upright post is provided with a handle at one side far away from the clamping piece.

Compared with the prior art, the utility model has the following advantages:

according to the positioning chain dismounting device, the chain can be conveniently and quickly clamped and fixed through the cushion block and the wire sleeve capable of being adjusted up and down, the pin shaft of the chain is aligned to the blanking hole on the cushion block, the thimble rod part of the thimble penetrates through the central hole of the wire sleeve and is propped against the pin shaft, the head of the thimble is knocked by a hammer, the dismounting of the pin shaft can be realized, the whole dismounting process is convenient and quick, and time and labor are saved; and the thimble relies on the silk cover to carry out vertical direction, need not the staff to use vice centre gripping, can not smash the injury people's hand in the hammering process, and the thimble also can not deviate from accidentally, has guaranteed the security of dismantling the process.

Detailed Description

The following describes in detail the examples of the present utility model, which are implemented on the premise of the technical solution of the present utility model, and detailed embodiments and specific operation procedures are given, but the scope of protection of the present utility model is not limited to the following examples.

Referring to fig. 1 and 2, this embodiment discloses a positioning chain dismounting device, including base 1, be equipped with fixed block 2 and cushion 3 that upper and lower interval was arranged on base 1, open threaded hole on the fixed block 2, threaded connection has silk cover 4 in the threaded hole of fixed block 2, press from both sides the upper and lower both ends of tight chain in the top through silk cover 4 bottom and cushion 3, open at silk cover 4 center has the centre bore, thimble 5 includes thimble head 6 and thimble pole portion 7, thimble pole portion 7 passes the centre bore of silk cover 4 from top to bottom, open on the cushion 3 and supply the blanking hole 8 of the round pin axle whereabouts of chain, thimble pole portion 7 is coaxial with blanking hole 8.

The fixed block 2 is connected with one side of the cushion block 3 through a side plate 9, the fixed block 2, the cushion block 3 and the side plate 9 form a C-shaped clamping piece, the base 1 is provided with a stand column 10, and the clamping piece is fixedly arranged on the stand column 10 through the side plate 9. The side plates 9 and the upright posts 10 can be fixedly connected through screw connection. The upright post 10 is provided with a handle 11 at one side far away from the clamping piece, so that the whole chain remover is convenient to carry.

When the chain clamp is used, a chain to be disassembled is placed on the upper surface of the cushion block 3, the pin shaft of the chain is aligned with the blanking hole 8 of the cushion block 3, and then the wire sleeve 4 is rotated, so that the wire sleeve 4 moves downwards until the bottom end of the wire sleeve 4 abuts against the upper surface of the chain, and the chain is stably clamped. Then, a thimble 5 is inserted into the center hole of the wire sleeve 4, the bottom of the thimble 5 just abuts against the top end of the pin shaft, the thimble head 6 is knocked by a hammer, the pin shaft can be knocked out downwards, and the knocked pin shaft falls out downwards from the blanking hole 8 of the cushion block 3. The whole operation process does not need to be hand, the center hole of the wire sleeve 4 is utilized to vertically guide the thimble 5, the thimble 5 cannot be separated, and potential safety hazards are eliminated.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
