Abstract
The utility model relates to an external floating clamping mechanism with a spring expansion self-locking function, belonging to machine tool fixtures. A connecting base is fixedly connected with a body; a cylindrical pin and a spring II are placed into holes in the connecting base; an expansion pressure block is placed in the connecting base; a pull rod is positioned in the expansion pressure block, and the conical end of the pull rod is connected with one end of the expansion pressure block through an oblique surface; a spring I is sleeved outside the pull rod; a compression block sleeves outside the pull rod, and is positioned in the expansion pressure block; one end of the compression block is in compression joint with the spring; a nut is in threaded connection with one end of the pull rod, and is pressed against the compression block; an anti-rotation key is connected with the expansion pressure block in an insertion manner, and is positioned in a groove on the pull rod. The external floating clamping mechanism has the advantages of novel structure, safety, reliability, wide application range, and convenience in use and high efficiency particularly in various workpieces clamped by means of outlines.
Description
Technical field
The utility model belongs to a kind of jig.
Background technology
Any jig all must consider that workpiece is adding the stressing conditions in man-hour, cutting deformation etc. in the time of design.In order to increase the cutting rigidity of workpiece, conventionally below the hold-down mechanism increasing, supplemental support must be installed, supplemental support has the forms such as manual and hydraulic pressure, and manual supplemental support is more loaded down with trivial details in use, though the handy cost of the supplemental support of hydraulic pressure is higher.In order to make up the deficiency of workpiece cutting rigidity, and easy to use efficient, safe and reliable.
Summary of the invention
The utility model provides a kind of outside float clamp mechanism with the self-locking of spring ringfeder, the use inconvenience existing to solve existing supplemental support, the problem that cost is high.
The technical scheme that the utility model is taked is: Connection Block is fixedly connected with body, straight pin and spring two are placed in the hole on Connection Block, ringfeder briquetting is placed in Connection Block, the tapering point that pull bar is positioned at ringfeder briquetting and pull bar is connected by inclined-plane with ringfeder briquetting one end, spring one is socketed in pull bar outside, compact heap is socketed in pull bar outside and is positioned at ringfeder briquetting, one end of this compact heap and spring one crimping, nut be connected with the threaded one end of pull bar and with compact heap apical grafting, antirotation keys and the cross-under of ringfeder briquetting and be positioned at the groove on pull bar.
The utility model has the advantages that: novel structure, safe and reliable and of many uses, especially in the tight all kinds of workpiece of outer clevis, easy to use, efficient.Remove from and using with supplemental support and the shared form of hold-down mechanism simultaneously, and mechanism is with self-locking device, make part to add man-hour safer more reliable, its unique clamping mode has been used widely and has been approved in reality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Connection Block 7 is fixedly connected with body 8, straight pin 6 and spring 29 are placed in the hole on Connection Block 7, ringfeder briquetting 5 is placed in Connection Block 7, the tapering point that pull bar 2 is positioned at ringfeder briquetting 5 and pull bar 2 is connected by inclined-plane with ringfeder briquetting one end, spring 1 is socketed in pull bar 2 outsides, compact heap 4 is socketed in pull bar 2 outsides and is positioned at ringfeder briquetting 5, one end of this compact heap 4 and spring one 3 crimping, nut 1 be connected with the threaded one end of pull bar 2 and with compact heap 4 apical graftings, antirotation keys 10 is with 5 cross-under of ringfeder briquetting and be positioned at the groove on pull bar 2.
When work, fastening nut 1, compact heap 4 is with ringfeder briquetting 5 to workpiece movable compression, and ringfeder briquetting 5 is subject to the inclined-plane power of pull bar 2 simultaneously, with Connection Block 7 tensioners, realizes self-locking.In the time of off working state, turn on nut 1, ringfeder briquetting 5 returns to original diameter dimension, and spring 3 is pushed compact heap 4 and ringfeder briquetting 5 open to both sides, and workpiece can unload.Can guarantee that like this workpiece is adding the cutting rigidity in man-hour, reduce deflection.For using the utility model can obtain larger clamping force, in the situation that not destroying original location and clamping, meet the requirement that workpiece is increased to cutting rigidity in the fixture of existing location and clamp mechanism.
Claims (1)
1. the outside float clamp mechanism with the self-locking of spring ringfeder, it is characterized in that: Connection Block is fixedly connected with body, straight pin and spring two are placed in the hole on Connection Block, ringfeder briquetting is placed in Connection Block, pull bar is positioned at ringfeder briquetting, and the tapering point of pull bar is connected by inclined-plane with ringfeder briquetting one end, spring one is socketed in pull bar outside, compact heap is socketed in pull bar outside, and be positioned at ringfeder briquetting, one end of this compact heap and spring one crimping, nut is connected with the threaded one end of pull bar, and with compact heap apical grafting, antirotation keys and the cross-under of ringfeder briquetting, and be positioned at the groove on pull bar.
