Description when being related to attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.
As depicted in figs. 1 and 2, the disclosure provides a kind of pin removal, which includes sliding bar 1, is respectively arranged at cunning
The block 2 and knockout screw 3 at 1 both ends of lever, and the sliding hammer 4 being axially slidably set on sliding bar 1, wherein tear open
The end that screw 3 is removably attached to sliding bar 1 by mounting structure is unloaded, specifically, which includes and sliding bar 1
The fixed block 51 being connected, and rotatably cooperate with fixed block 51 spill spin block 52 for fixing knockout screw 3, it rotates above-mentioned
Spill spin block 52 is to predeterminated position, to dismantle or lock knockout screw 3.Here, it should be noted that knockout screw 3 can be energy
The screw of enough different structures being threadedly coupled with the threaded hole on positioning pin, such as soket head cap screw, fixed block 51 and spill spin block
52 are rotatably engaged, adjustment spill spin block 52 relative to fixed block 51 position, it can be achieved that knockout screw 3 disassembly and peace
Dress, is conveniently replaceable, to adapt to the positioning pin of different size, or it is steadily connected to the end of sliding bar 1, and then completes
The dismantlement work of positioning pin.
Through the above technical solutions, according to the specification of pre- disassembly positioning pin, turning in the pin removal provided using the disclosure
Spill spin block 52 is moved to replace suitable knockout screw 3, and it is steadily connected to the end of sliding bar 1, by 3 He of knockout screw
Positioning pin is connected, and operator holds sliding hammer 4 along the quick sliding from the bottom to top of sliding bar 1, passes through sliding hammer 4 and block 2
Shock positioning pin is extracted, and then complete positioning pin dismantlement work.The pin removal that the disclosure provides can realize different size
The disassembly of positioning pin, it is easy to operate, greatly improve working efficiency.
Spill spin block 52 is relative to there are many rotatable connection types of fixed block 51.In the disclosure, as shown in Figure 1, it is solid
Determine the end that block 51 is threaded in sliding bar 1, spill spin block 52 can be the sleeve being set on fixed block 51, on fixed block 51
It is formed with spacer pin 511, is formed on spill spin block 52 circumferentially for accommodating the limiting slot 521 of spacer pin 511.Limiting slot
521 can be the strip slot being formed on spill spin block 52, and spill spin block 52 can be relative to solid in the length range of strip slot
Determine block 51 to circumferentially rotate, spacer pin 511 and limiting slot 521 match the connection of achievable fixed block 51 and spill spin block 52.
Specifically, in the disclosure, as depicted in figs. 1 and 2, the lower end of 52 side wall of spill spin block is formed with gap 522, fixed
The lower end of block 51 is formed with the open slot 512 on the head for accommodating knockout screw 3, rotates spill spin block 52, when gap 522 and opens
When the aperture position of mouth slot 512 is corresponding, knockout screw 3 can be deviate from or be entered by gap 522, can carry out tearing open for knockout screw 3
It unloads and replaces；Spill spin block 52 is rotated backward, when the closed front gap 522 of fixed block 51, knockout screw 3 and 52 phase of spill spin block
It connects and locks, the dismantlement work of positioning pin can be carried out, in this way, by quick-replaceable knockout screw 3, which is applicable to
The disassembly of the positioning pin of different size solves the problems, such as that existing pin removal is of numerous names, realizes the General design of pin removal.
Further, in the disclosure, spacer pin 511 and open slot 512 are located on same axis, as shown in Figure 1, when suitable
When hour hands rotate 52 to the first extreme position of spill spin block, the aperture position of gap 522 and open slot 512 is corresponding, knockout screw 3
It can be deviate from or be entered by gap 522；As shown in figure 3, when rotating counterclockwise 52 to the second extreme position of spill spin block, fixed block 51
Closed front gap 522, knockout screw 3 is connected and locks with spill spin block 52.In the first extreme position, it can be achieved that rotation
The locking of block 52, while can also ensure that the aperture position of gap 522 and open slot 512 is corresponding, and then will quickly dismantle spiral shell
Nail 3 is removed or is packed by gap 522；In the second extreme position, it can be achieved that the locking of spill spin block 52, while can also ensure that solid
Determine the closed front gap 522 of block 51, realizes being stably connected with for knockout screw 3 and spill spin block 52.
The head of knockout screw 3 is contained in the open slot 512 of fixed block 51 upper limit, it can be achieved that knockout screw 3,
To realize the lower limit to knockout screw 3, as shown in Figure 1, the lower end of spill spin block 52 is formed with for the head to knockout screw 3
The annular projection 523 limited, knockout screw 3 may pass through annular protrusion 523 and be stably connected with spill spin block 52.Further,
In the present embodiment, for convenience of knockout screw 3 by deviating from gap 522 or entering, the axial height of gap 522 can be greater than
The height on 3 head of knockout screw.
To realize being stably connected with for fixed block 51 and spill spin block 52, in the present embodiment, as shown in Fig. 2, fixed block 51
Outer wall on be also formed with the lugs 513 of multiple circumferentially spaced settings, the inner wall of spill spin block 52 is pressed together on multiple lugs 513,
And then realize being stably connected with for the two.
In addition, in the disclosure, as shown in Figure 1, sliding hammer 4 can be formed as dumbbell-shaped structure, the dumbbell-shaped structure packet
Include the interlude 41 that can be axially moved relative to sliding bar 1 and the tapered portion 42 for being formed in 41 both ends of interlude.Dumbbell-shaped structure
The more convenient gripping of sliding hammer 4, improve operator use the pin removal comfort, meet the design of ergonomics
Principle.
As shown in Figure 1, block 2 can be the cylinder for being fixed on 1 top of sliding bar, the diameter of axle difference of 42 end face of tapered portion is big
In the diameter of axle of block 1 and fixed block 51, in this way, when the quickly movement from the bottom to top of sliding hammer 4, it is possible to increase with the contact of block 2
Area applies biggish impact force to block 2, to drive positioning pin to extract.
The preferred embodiment of the disclosure is described in detail in conjunction with attached drawing above, still, the disclosure is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the disclosure, a variety of letters can be carried out to the technical solution of the disclosure
Monotropic type, these simple variants belong to the protection scope of the disclosure.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, can be combined in any appropriate way, in order to avoid unnecessary repetition, the disclosure to it is various can
No further explanation will be given for the combination of energy.
In addition, any combination can also be carried out between a variety of different embodiments of the disclosure, as long as it is without prejudice to originally
Disclosed thought equally should be considered as disclosure disclosure of that.
