Abstract

The invention relates to a locating mechanism, in particular to a spring pin telescoping mechanism used in the machining process of blank location holes. The spring pin telescoping mechanism comprises a fixture plate. A guide holder is fixed to the upper portion of the fixture plate, and a linear cylinder is fixed to the bottom of the fixture plate. A piston rod of the linear cylinder penetrates out of the fixture plate and extends into a guide hole of the guide holder. A pull rod is connected to the end of the piston rod, a locating sleeve is fixed in the guide hole, and the pull rod is fixedly connected to an inner hole of the locating sleeve through a transversely-arranged round pin. A spring pin is arranged in the locating sleeve, a spring is arranged in a counter bore in the bottom of a locating pin, the bottom end of the spring abuts against an adjusting screw tightly, and the adjusting screw is arranged in the locating sleeve in a screwed mode and corresponds to the upper portion of the round pin. The spring pin telescoping mechanism is simple and reasonable in structure; through additional arrangement of the linear cylinder, the linear cylinder can be used for pulling down the spring pin when the spring pin needs to avoid a tool, and therefore the tool can be avoided.

Description

Resilient key telescoping mechanism
Technical field
The present invention relates to a kind of detent mechanism, especially a kind of resilient key telescoping mechanism using for blank locating hole process.
Background technology
When clamping tool for machine work designs, often can run into endoporus blank location, but locating hole needs processing, traditional resilient key structure cannot be stretched and be dodged the situation of cutter.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of resilient key telescoping mechanism is provided, adopt this mechanism effectively to realize resilient key and dodge cutter.
According to technical scheme of the present invention: a kind of resilient key telescoping mechanism, it is characterized in that: comprise jig plate, described jig plate top is fixed with guide holder, jig plate bottom is fixed with straight line cylinder, the piston rod of described straight line cylinder passes from jig plate, and stretch in the pilot hole of guide holder, end at piston rod is connected with pull bar, in described pilot hole, be fixed with positioning sleeve, pull bar is fixedly connected in positioning sleeve endoporus by the circular pegs of horizontally set, resilient key is arranged in positioning sleeve, and in the counterbore of alignment pin bottom, a spring is set, described spring bottom holds out against in adjustment screw, described adjustment screw is revolved and is located in positioning sleeve, upper position place corresponding to circular pegs.
As a further improvement on the present invention, described guide holder is connected in jig plate by the first screw fastening.
As a further improvement on the present invention, described resilient key top is set to cone-shaped.
As a further improvement on the present invention, described resilient key outer peripheral face is fixed with cylinder holding screw, and the cylinder termination of cylinder holding screw is resisted against on positioning sleeve inwall.
Technique effect of the present invention is: product structure advantages of simple of the present invention, by increasing a straight line cylinder, make when needs are dodged cutter, can resilient key be pulled down by straight line cylinder so that realize and dodge cutter, specifically by guide holder, in the pilot hole of positioning sleeve, moved up and down to realize, so both locate workpiece, do not affected again the processing of blank locating hole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, comprise straight line cylinder 1, jig plate 2, guide holder 3, pull bar 4, circular pegs 5, adjustment screw 6, spring 7, positioning sleeve 8, resilient key 9, workpiece 10, cylinder holding screw 11, the first screw 12, the second screw 13 etc.
As shown in Figure 1, the present invention is a kind of resilient key telescoping mechanism, comprise jig plate 2, described jig plate 2 tops are fixed with guide holder 3, jig plate 2 bottoms are fixed with straight line cylinder 1, the piston rod of described straight line cylinder 1 passes from jig plate 2, and stretch in the pilot hole of guide holder 3, in the end of piston rod, be connected with pull bar 4, in described pilot hole, be fixed with positioning sleeve 8, pull bar 4 is fixedly connected in positioning sleeve 8 endoporus by the circular pegs 5 of horizontally set, resilient key 9 is arranged in positioning sleeve 8, and in alignment pin 9 bottom counterbores, a spring 7 is set, described spring 7 bottoms hold out against in adjustment screw 6, described adjustment screw 6 is revolved and is located in positioning sleeve 8, upper position place corresponding to circular pegs 5.
Described guide holder 3 is fastenedly connected in jig plate 2 by the first screw 12.
Described resilient key 9 tops are set to cone-shaped.
Described resilient key 9 outer peripheral faces are fixed with cylinder holding screw 11, and the cylinder termination of cylinder holding screw 11 is resisted against on positioning sleeve 8 inwalls.
The operation principle of product of the present invention is as follows: taper is arranged to in resilient key 9 tops, so that adapt to the different diameter of workpiece 10 blank hole, cylinder holding screw 11 can limit the angle of resilient key 9, by adjustment screw 6, can adjust the strength of spring 7, make resilient key 9 can not only be close to blank hole but also can be workpiece jack-up, guide holder 3 is fixed on jig plate 2 by the first screw 12, by straight pin 5, positioning sleeve 8 is moved up and down in pilot hole simultaneously.
Straight line cylinder 1 drives resilient key 9 to stretch out, and location blank hole, then by pressing plate clamping work pieces 10, is finally passed through the retraction of the piston rod of straight line cylinder 1, drives resilient key 9 to depart from blank hole, has so both located workpiece 10.Do not affect again the processing of blank locating hole.
