A kind of double end pin pressing machine
Technical field
The utility model relates to a kind of pin pressing machine, relates in particular to the double end pin pressing machine that can carry out two place's pads simultaneously.
Background technology
The component of machine of automobile is generally specific vehicle and designs and customize, shape also is very strange, of all kinds, simultaneously in order to meet safety standard, need to bear very big impulsive force and pressure etc., generally all can require one time punching moldedly, so each parts assemble up if desired, sometimes will be very complicated.
Crossbeam assembly as shown in Figure 1 because about all to use pin-and-hole, so when assembling both sides all to carry out the pad operation.This assembly is just can carry out the pad operation after moulding, use one of the every assembling of present pin pressing machine all to need to carry out twice pad operation, and because the size of the pin-and-hole on both sides and inequality, therefore whenever carrying out a pad operation all will change the tool fixture that pad is used again, very trouble and time-consuming is neglected the difference that also can cause because of the problem that tool is installed on the pad quality a little.And if carry out on one side pad operation earlier, carry out the pad operation of another side again, can pile up a large amount of semi-finished product in the pad operation again, and huge part both had been not easy to stack, in stacking, also be difficult to carry out quality management.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of double end pin pressing machine, solves the defective of the time-consuming and wayward quality of prior art.
Technical scheme
A kind of double end pin pressing machine comprises frame and pad head, it is characterized in that: described pad head is about being installed on the frame each one, under each pad head fixed head is installed, and anchor clamps are housed on the fixed head, and the cylinder of control pad head compression distance is housed on the pad head.
Fixed head under described one of them pad head is the X that is made up of ball-screw to slide unit and Y to slide unit.
The Z of two fixed heads is to highly identical about described.
Two fixed heads adopt knurled nut about described in the pad hole site.
Beneficial effect
Double end pin pressing machine of the present utility model increases a pad head on the basis of existing pin pressing machine, and adopts cylinder directly to control the compression distance of each pad head respectively, the pad action that needs are finished for twice once can be finished, and also accurately efficient.
Description of drawings
Fig. 1 is the utility model embodiment middle cross beam assembly schematic diagram.
Fig. 2 is the utility model schematic diagram.
Wherein: the 1-frame, 2-pad head, the 3-fixed head, the 4-anchor clamps, 5-cylinder, 31-X are to slide unit, and 32-Y is to slide unit.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
A kind of double end pin pressing machine comprises frame 1 and pad head 2, and described pad head 2 is about being installed on the frame 1 each one, and each pad head is equipped with fixed head 32 times, and anchor clamps 4 are housed on the fixed head 3, and the cylinder 5 of control pad head 2 compression distances is housed on the pad head 2.Crossbeam assembly as shown in accompanying drawing 1, respectively there is a pad hole that needs pad on both sides, the position symmetry in two pad holes, but fixing anchor clamps form difference, necessary twice pad during with front press pin, and change anchor clamps, use the double end pin pressing machine now, have after two pad heads, the pad action that needs are finished for twice once can be finished, and accurately efficient.Described cylinder 5 can be connected to same starting switch, starts pad synchronously, also can separately connect switch, the checkout equipment that follow-up connection is different.
Fixed head 3 under described one of them pad head 2 can make the X that forms by ball-screw to slide unit 31 and Y to slide unit 32.When one of them pad hole site changes, can adjust easily like this.The Z of two fixed heads 3 is convenient to control at grade to highly identical about described.
Described left and right sides fixed head 3 adopts knurled nut in the pad hole site.
Double end pin pressing machine of the present utility model increases a pad head on the basis of existing pin pressing machine, and adopt cylinder directly to control the compression distance of each pad head respectively, and can carry out detecting simultaneously behind the synchronous pad, improve production efficiency and be convenient to quality control.
