Abstract
The invention relates to an elastic locating pin comprising an elastic pin, a pin seat, an adjusting bolt and a spring; the elastic pin is matched in the pin seat in a sliding mode and protrudes out of one end of the pin seat; the other end of the pin seat is fixedly provided with a limiting screw cap; the adjusting bolt is screwed in the limiting screw cap; and the spring is assembled between the adjusting bolt and the elastic pin. According to the invention, the limiting screw cap is additionally arranged at the end of the pin seat, when the elastic pin does not enter a locating hole of a workpiece, the limiting screw cap can stop the elastic pin from being pressed to the bottom, a worker can discover that the workpiece is not clamped in situ in time, in this way, the elastic pin can be enabled to enter the locating hole of the workpiece so as to locate the workpiece reliably.
Description
Technical field
The present invention relates to the frock clamp of machinery industry, specifically a kind of elastic positioning pin.
Background technology
Elastic positioning pin plays the role of positioning when batch machining foundry goods.In general, that carries out foundry goods first operation adds man-hour, adopts one side 3 to add two elastic positioning pin location often, utilizes the conical surface of elastic positioning pin to play certralizing ability.
Existing elastic positioning pin as shown in Figure 1, comprise resilient key 1, key seat 2, adjustment screw 6 and spring 7, resilient key 1 is slidably fitted in key seat 2, key seat 2 has been threaded adjustment screw 6, be equipped with spring 7 between adjustment screw 6 and resilient key 1, resilient key 1 stretches out key seat 2 under the effect of spring 7.When with this elastic positioning pin location, if workman does not slightly note when clamping workpiece just easily producing waste product, main cause is: workman cannot see alignment pin when clamping workpiece, and resilient key 1 is easily pressed onto the end by workpiece, makes resilient key 1 not enter locating hole, but workpiece can touch three positioning supports, such elastic positioning pin does not play the role of positioning, and workman also cannot see this situation, and the workpiece processed so is all scrapped, and easily cutter is hit in generation, affects machine tool accuracy time serious.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of elastic positioning pin preventing workman's clamping instability, this alignment pin can ensure that Workpiece fixing is reliable.
According to technical scheme of the present invention: a kind of elastic positioning pin, comprise resilient key, key seat, adjustment screw and spring, described resilient key to be slidably fitted in described key seat and to stretch out from one end of described key seat, the other end of described key seat is fixed with spacing blind nut, be threaded in described spacing blind nut described adjustment screw, is equipped with described spring between described adjustment screw and described resilient key.
Described spacing blind nut is threaded on described key seat.
Described resilient key and the relative end face of described adjustment screw are respectively arranged with groove, and the two ends of described spring are arranged in two described grooves respectively.
The sidewall of described resilient key is provided with axially extended chute, and described key seat has been threaded anti-turn bolt, and the tail end of described anti-turn bolt stretches in described chute.
Described key seat is provided with mounting flange, under described mounting flange, is lined with trimmer.
Technique effect of the present invention is: the present invention adds spacing blind nut in the end of key seat, when resilient key does not enter the locating hole of workpiece, spacing blind nut can stop resilient key to be pressed onto the end, workman can not have clamping to put in place by Timeliness coverage workpiece, can guarantee that resilient key enters the locating hole of workpiece, workpiece is reliably located.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing elastic positioning pin.
Fig. 2 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ Fig. 2, comprise resilient key 1, key seat 2, trimmer 3, anti-turn bolt 4, spacing blind nut 5, adjustment screw 6, spring 7, groove 8, chute 9, mounting flange 10 etc.
As shown in Figure 2, the present invention is a kind of elastic positioning pin, comprises resilient key 1, key seat 2, adjustment screw 6 and spring 7, key seat 2 is provided with mounting flange 10, by the bolt through mounting flange 10, key seat 2 is fixed on fixture, is lined with trimmer 3 10 times at mounting flange, play corrective action.
Resilient key 1 to be slidably fitted in key seat 2 and to stretch out from one end of key seat 2, and the other end of key seat 2 is fixed with spacing blind nut 5, and spacing blind nut 5 is preferably threaded on key seat 2.Be threaded adjustment screw 6 in spacing blind nut 5, is equipped with spring 7 between adjustment screw 6 and resilient key 1.By the elastic force regulating adjustment screw 6 to adjust resilient key 1.
Resilient key 1 and the relative end face of adjustment screw 6 are respectively arranged with groove 8, and the two ends of spring 7 are arranged in two grooves 8 respectively, facilitate the installation of spring 7.
The sidewall of resilient key 1 is provided with axially extended chute 9, and key seat 2 has been threaded anti-turn bolt 4, and the tail end of anti-turn bolt 4 stretches in chute 9.Anti-turn bolt 4 can prevent resilient key 1 from rotating in key seat 2.
The present invention adds spacing blind nut 5 in the end of key seat 2, when resilient key 1 do not enter the locating hole of workpiece, workpiece push down resilient key 1 time, spacing blind nut 5 can withstand resilient key 1, stop it to be pressed onto the end, such workpiece just resists on alignment pin, makes on its three positioning supports that can not touch on fixture, by vision or feel, workman just can find that workpiece does not have clamping to put in place, then can adjust the position of workpiece, make resilient key 1 enter the locating hole of workpiece, thus workpiece is reliably located.
The present invention is simple and reliable for structure, easy to maintenance.
