Fig. 1 to Fig. 3 is referred to, the automatic demoulding component 10 includes base 1, the fixture being arranged on the base 1 2nd, the elastic component 3 that is arranged in the fixture 2, the demoulding thimble 4 being arranged in the fixture 2 and it is fixed on the fixation First 5 are pressed on part 2.Described press first 5 is fixed on fixture 2 by connector 6.

The fixture 2 can be relative to the base 1 along the elastic component 3 compression direction move, the fixture 2 has Offered in outer bottom 21 and the outer top surface 22 for setting of being supported or opposed with the outer bottom 21, the fixture 2 through the outer bottom 21 accommodating chamber 23, the elastic component 3 is accommodated in the accommodating chamber 23, and the accommodating chamber 23 has inner top surface 24, described solid Determine to be further opened with the through hole 35 of the outer top surface 22 through the inner top surface 24 and the fixture 2, the demoulding thimble 4 on part 2 It is arranged in the through hole 35, and can be moved in the through hole 35 along the compression direction of the elastic component 3, the demoulding thimble 4 first 5 and can move in first 5 through described press in described press along the compression direction of the elastic component 3；The demoulding thimble 4 One end and one end of elastic component 3 support, the other end of the demoulding thimble 4 stretches to described press in first 5.

In the present embodiment, in order to protect elastic component 3 and demoulding thimble 4, the demoulding thimble 4 and the elastic component 3 it Between be provided with pad 7.In the present embodiment, the demoulding thimble 4 is set with pad 7 for split, really, the demoulding thimble 4 and pad Piece 7 can also be structure as a whole.Further：The diameter of the pad 7 is identical with the diameter of elastic component 3.In the present embodiment, institute It can be stage clip to state elastic component 3, and the stage clip 3 is Rectangular Spring.For the ease of being connected with piston rod, the accommodating chamber 23 Depth is more than length of the elastic component 3 under conventional sense, is provided with the inwall of the accommodating chamber 23 outer with piston rod Screw thread realizes the internal thread (not shown) of threaded connection, certainly, in other embodiments, can also pass through other attachment structures Fixture 2 is connected with piston rod.

The base 1 includes limit base 11 and the regulation cover 12 being set on the limit base 11, and the limit base 11 is wrapped The containing cavities 111 through the limit base 11 are included, the fixture 2 is at least partially disposed in the containing cavities 111, the fixation The bottom of part 2, which is protruded outward, is formed with limited block 26；The limited block 26 is located in the containing cavities 111, and can be with described solid Determine the relative limit of part 2 seat 11 to move along the compression direction of the elastic component 3；The regulation cover 12, which has, is located at the limit base 11 The stop wall 121 of top, and containing cavities 111 described in shield portions, the stop wall 121 are located at the top of limited block 26；When described When limited block 26 is moved a certain distance in the containing cavities 111, the stop wall 121 supports the limited block 26 and limits institute Limited block 26 is stated to move.The regulation cover 12 can be adjusted relative to the limit base 11 in the telescopic direction movement of elastic component 3 The mechanical position limitation of squeeze riveter, in order to manufacture in the attachment structure of regulating part and limit base 11, the present embodiment, it is described regulation cover 12 with It is connected through a screw thread between the limit base 11.Scale is provided with the regulation cover 12, fixation is recognized that by the scale The movable distance of part 2.

The operation principle of above-mentioned automatic demoulding component 10 is as follows：

Piston rod is connected with fixture 2 first, now, due to being provided with external screw thread, the receiving of fixture 2 on piston rod Internal thread is provided with chamber 23, is connected the piston rod with fixture 2 so as to be connected through a screw thread, when piston rod is attached to appearance After chamber 23 of receiving is interior, piston rod produces compression elastic piece 3 certain pretightning force, and elastic component 3 is pre- by demoulding thimble 4 by pad 7 Tightly.

When the piston rod stretches out, described press first 5 contacts with pin (not shown) and extrudes pin, pin pars intermedia Point extruding demoulding thimble 4 simultaneously further compresses the elastic component 3, when press end after, piston rod is retracted, described to press It is first 5 depart from pin, in the presence of the elastic component 3, the resilience under spring force of demoulding thimble 4, by pin with Described press first 5 is forcibly separating, so as to realize automatic demoulding.

The limit base 11 is fixed on board (not shown), and regulation cover 12 is connected by screw thread with limit base 11, is passed through Adjustment regulation cover 12 realizes the mechanical position limitation of squeeze riveter, and the distance of the mechanical position limitation needs to preset, its distance as fixture 2 Displacement, because the distance can be preset, so, can be referred to as pre-determined distance.When piston rod stretches out, piston rod band Dynamic fixture 2 is moved, and after certain distance (pre-determined distance) is reached, now, i.e., the limited block 26 of described fixture 2 is described When being moved a certain distance in containing cavities 111, the stop wall 121 of the regulation cover 12 is contacted with the limited block 26 so that backstop Wall 121 is mutually supported with the limited block 26, is moved so as to limit the limited block 26, that is, realizes the machinery limit of squeeze riveter Position.

In summary, above-mentioned automatic demoulding component 10 is by using elastic component 3, so as to when squeeze riveter is in pressing in pins Produce a pretightning force, and then complete after pin installs, first 5 separated pin with pressing by the thrust of the elastic component 3, To realize the function of automatic demoulding.And the squeeze riveter of the automatic demoulding component 10 is installed when in use, due to its can realize from The function of the dynamic demoulding, so, its operating efficiency is favorably improved, the working strength of workman is reduced, further, can be conducive to Realize automated production.

Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, the scope of this specification record is all considered to be.

Embodiment described above only expresses several embodiments of the present utility model, and it describes more specific and detailed, But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that for the common skill of this area For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to Protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
