Description

A kind of clamping device
Technical field
It the utility model is related to machining equipment technical field, more particularly to a kind of clamping device.
Background technology
In machining, clamping device is a kind of essential device.Such as Digit Control Machine Tool, only in clamping device very The accurate processing to workpiece could be completed under conditions of good clamping band processing materials.Basic clamping is played in existing clamping device The part of effect mainly has voussoir, helical member, eccentric part and lever etc., and the clamping device combined by them.It is but existing Some clamping devices cannot be guaranteed the stability of workpiece, and in processed complex part such as bore hole etc., caused displacement tolerance is larger, no Can guarantee that the accuracy of part, and under drive mechanism drive easily because stress is excessive and in clamping process defective work piece.
Utility model content
The purpose of this utility model is, there is provided a kind of clamping device, to overcome above-mentioned technological deficiency.
Concrete technical scheme is as follows:
A kind of clamping device, including two fixed blocks be arrangeding in parallel, two gripping blocks arranged in parallel, two pieces it is slow Punching and two hydraulic cylinders, the relative side of two fixed blocks offer horizontally disposed sliding-rail groove together respectively inwards, often The both ends of one gripping block are respectively provided with the sliding block to match with sliding-rail groove, and sliding block is horizontally slidable is fitted in sliding-rail groove, two The relative side of gripping block offers the groove of semicircular in shape respectively inwards;
Side of each gripping block away from another gripping block is connected with a buffer board, and buffer board by more stage clips Edges at two ends it is horizontally slidable be fitted in sliding-rail groove, side of each buffer board away from gripping block is provided with one Hydraulic cylinder, hydraulic cylinder is horizontally disposed with and the connected buffer board in the end of piston rod;
Side of each gripping block away from another gripping block is respectively arranged with least two guide rods, and level is passed through on buffer board That wears offers the through hole with the quantity such as guide rod, and each guide rod penetrates buffer board via corresponding through hole and the limited location spiral shell that is spirally connected It is female.
Preferably, on two madial walls relative in sliding-rail groove respectively embedded with it is multiple can free rolling ball.
Preferably, the quantity for the guide rod installed in each gripping block is two.
The beneficial effect of above-mentioned technical proposal is:
Two hydraulic cylinders drive two gripping block move toward one anothers to clamp workpiece by buffer board, and buffer board and gripping block Between by stage clip be connected clamping process more gently and uniform force, effective cushioning effect can be played, will not be because of liquid Cylinder pressure driving force is excessive and periphery of the defective work piece in workpiece fabrication is clamped, and simple for structure easy to use.
Brief description of the drawings
Fig. 1 is the installation diagram of the utility model clamping device;
Fig. 2 is the cross-sectional view of fixed block in the utility model clamping device;
Fig. 3 is the positive structure schematic of gripping block in the utility model clamping device.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, with Lower 1 to 3 pair of clamping device provided by the utility model of embodiment combination accompanying drawing is specifically addressed.
Refering to Fig. 1, for the installation diagram of clamping device;It is that the cross-section structure of fixed block in clamping device is illustrated with reference to Fig. 2 Figure;And Fig. 3, for the positive structure schematic of gripping block in clamping device.For the architectural feature of clear display the present embodiment, figure Middle omission shows part-structure, and part-structure is then shown in a manner of perspective or section view.
As shown in Figure 1 to Figure 3, clamping device provided by the utility model includes two fixed blocks 1, two be arrangeding in parallel Individual gripping block 2 arranged in parallel, two block buffering plates 3 and two hydraulic cylinders 4, and the side point that two fixed blocks 1 are relative Horizontally disposed sliding-rail groove 8 together is not inwardly offered, and the both ends of each gripping block 2 are respectively provided with the sliding block to match with sliding-rail groove 8 11, and sliding block 11 is horizontally slidable is fitted in sliding-rail groove 8, two relative sides of gripping block 2 offer and are in respectively inwards Semicircular groove 10, workpiece is clamped to close up in relative motion and fill the span of a man's arms;Each gripping block 2 is away from another gripping block 2 Side be connected with a buffer board 3 by more stage clips 5, and horizontally slidable equipped of the edges at two ends of buffer board 3 In in sliding-rail groove 8, each side of the buffer board 3 away from gripping block 2 is provided with a hydraulic cylinder 4, hydraulic cylinder 4 it is horizontally disposed and The connected buffer board 3 in the end of piston rod, to drive the move toward one another of two block buffering plate 3, and then band under two drivings of hydraulic cylinders 4 Dynamic two move toward one anothers of gripping block 2 clamp workpiece;Side of each gripping block 2 away from another gripping block 2 is respectively arranged with least Two guide rods 6, and the horizontal through hole offered with the quantity such as guide rod 6 run through on buffer board 3, each guide rod 6 is via corresponding Through hole penetrate buffer board 3 and be bolted with stop nut 7, limit the position being mutually shifted between buffer board 3 and gripping block 2 to play Path is moved, prevents sideslip.
In the above-mentioned technical solutions, two hydraulic cylinders 4 drive two move toward one anothers of gripping block 2 to clamp by buffer board 3 Workpiece, and it is connected by stage clip 5 that clamping process is more gentle and uniform force between buffer board 3 and gripping block 2, it can play Effective cushioning effect, will not because the driving force of hydraulic cylinder 4 is excessive and the defective work piece in workpiece fabrication is clamped periphery, and structure It is succinct easy to use.
In a preferred embodiment, specifically as shown in Figure 2, divide on two madial walls relative in sliding-rail groove 8 Not Qian Zhuanyou it is multiple can free rolling ball 12, to auxiliary clamp block 2 and the horizontal sliding process of buffer board 3, while not The problem of being easy to wear the wall of sliding-rail groove 8 after long-term use and cause levelness Different Effects machining accuracy.Further, The quantity for the guide rod 6 installed in each gripping block 2 is two.
Preferred embodiment of the present utility model is the foregoing is only, is merely illustrative for the utility model, and It is nonrestrictive.Those skilled in the art understanding, can be to it in the spirit and scope that the utility model claims are limited Many changes are carried out, are changed, in addition it is equivalent, but fall within the scope of protection of the utility model.
