Abstract
The utility model relates to a fast switching positioning pin for a welding clamp unit. The fast switching positioning pin is used for solving the problems that the ordinary positioning pin occupies a great space when being dismounted and mounted, and the operation is complicated. The fast switching positioning pin has the technical scheme that the positioning pin is positioned on a fixed plate of a fixed clamp unit and consists of a positioning pin body, a spring, an installing sleeve, a connecting pin and a handle, wherein the spring is sheathed on the positioning pin body, the spring and the positioning pin are positioned in an inner hole of the installing sleeve, the upper part of the positioning pin body is connected with the handle through the connecting pin, the upper end of the installing sleeve is provided with two position limiting surfaces with different heights, and the lower end of the handle is provided with two position limiting surfaces with different lengths. The fast switching positioning pin has the following characteristics that: 1, the occupied space during the dismounting and the mounting is small, and the problem that the ordinary positioning pin cannot be used because of the dismounting and mounting limitation caused by narrow and small space is solved; 2, the operation is fast and convenient, the work intensity of operators is reduced, and the work efficiency is improved; 3, the rick of hand collision in the pulling process when a pin pulling device is used is avoided; and 4, the fast switching positioning pin is arranged on the clamping unit, and the loss of the positioning pin is avoided.
Description
Technical field
The utility model relates to a kind of keeper, especially for the quick switching alignment pin of weld jig unit.
Background technology
Automobile production enterprise is in the vehicle frame welding process, and in order to reach flexible production, multiple vehicle frame swinging cross is produced, and part weld jig unit need often switch, and needs the dismounting alignment pin in the fixture unit handoff procedure.Common alignment pin is built-in helicitic texture, needs during the installing and locating pin alignment pin to be pounded gently in the hole of assembling-welding fixtures substrate with hammer, when the dismounting alignment pin, need extract alignment pin with pin removal; In withdrawal process, at first to the bolt on the pin removal be screwed in the alignment pin screw thread; Firmly upwards mention then, alignment pin is extracted, the operation more complicated; Inefficiency is careless slightlyly damaged hand easily; Especially part clamp unit can't be dismantled after making common alignment pin be installed on the assembling-welding fixtures substrate, thereby cause fixture unit not switch because the limited space pin removal can not be connected with common alignment pin.
The utility model content
The utility model is used to solve the defective of above-mentioned prior art and provides weld jig unit that a kind of dismounting alignment pin takes up room little, simple operation with switching alignment pin fast.
The alleged problem of the utility model solves through following technical scheme:
A kind of weld jig unit is with switching alignment pin fast; Special feature is: it is positioned on the fixed head of stationary fixture unit, and its formation comprises alignment pin body, spring, installation sleeve, connecting pin and handle, and said spring housing is contained on the alignment pin body; Spring, alignment pin are arranged in the endoporus of installation sleeve; Alignment pin body top is connected with handle through connecting pin, and said installation sleeve upper end is provided with two confined planes that height differs, and said handle, at its lower end is provided with two confined planes different in size.
Above-mentioned weld jig unit is with switch alignment pin fast, and said alignment pin body is a hierarchic structure, and the endoporus of said installation sleeve is a shoulder hole, and the shaft shoulder of said alignment pin body and the shoulder hole of installation sleeve are spacing to both ends of the spring.
Above-mentioned weld jig unit is with switching alignment pin, the bottom arc surface transition of said alignment pin body fast.
Above-mentioned weld jig unit is with switch alignment pin fast, and said fixed head is provided with installing hole, and installation sleeve is arranged in this hole, adapter sleeve and installing hole interference fit.
The utility model takes up room big to common alignment pin dismounting and operation is complicated, ineffective problem is improved; Designed a kind of quick switching alignment pin of being convenient in the small space dismounting; Its characteristics are following: 1. dismounting takes up room for a short time, has solved the problem that can't use common alignment pin because space narrow and small dismounting is limited; 2. swift to operate, reduce operating personnel's working strength, increase work efficiency; 3. avoided the risk of using pin removal when pulling up process, hand to be collided with; 4. should switch alignment pin fast and be installed on the clamping unit, avoid losing of alignment pin.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model positioning states structural representation;
Fig. 3 is the utility model switching state structural representation.
Label is following in the accompanying drawing: 1. assembling-welding fixtures substrate, 2. lining, 3. alignment pin body, 4. fixed head, 5. installation sleeve, 6. spring; 7. connecting pin, 8. handle, 9. weld jig unit.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model is positioned on the fixed head 4 in order to stationary fixture unit 9, and its formation comprises alignment pin body 3, spring 6, installation sleeve 5, connecting pin 7 and handle 8.Said spring housing is contained on the alignment pin body, and spring, alignment pin are arranged in the endoporus of installation sleeve.Alignment pin body 3 is a hierarchic structure, and the endoporus of installation sleeve 5 is a shoulder hole, and the shaft shoulder position of alignment pin body and the shoulder hole of installation sleeve are spacing to spring 6 two ends, and alignment pin body top is connected with handle 8 through connecting pin 7.Said installation sleeve upper end is provided with two confined planes that height differs, and handle, at its lower end is provided with two confined planes different in size.Fixed head 4 is provided with installing hole, and installation sleeve 5 is arranged in this hole, adapter sleeve and installing hole interference fit.For making in the smooth and easy entering lining 2 of alignment pin body, the arc surface transition is adopted in the bottom of alignment pin body 3.
Still referring to Fig. 1, Fig. 2, this is that the utility model is in positioning states, when this state; The alignment pin body is under the spring force effect; Its underpart probes in the lining 2 that is installed in assembling-welding fixtures substrate 1, and the location is realized in weld jig unit 9, and alignment pin body and lining adopt the matched in clearance of H9/h9; This fit system both can satisfy positioning accuracy, can make again in the smooth and easy entering lining of alignment pin body.Touch at the short confined planes of positioning states lower handle 8 bottoms and the high confined planes on installation sleeve 5 tops.
Referring to Fig. 3, when needs switch Unit 9, weld jig unit, handle 8 is mentioned and half-twist, the long confined planes of handle 8 bottoms and the high confined planes on installation sleeve 5 tops are touched.At switching state, spring 6 is compressed, and the alignment pin body is retracted in the adapter sleeve, and the weld jig unit breaks away from positioning states, can carry out handover operation.
