Abstract

The utility model discloses a workpiece holder which relates to the technical field of clamps and comprises a fixed clamp die, a movable clamp plate and a clamp die installation plate, wherein the fixed clamp die consists of a fixed block and a plug bush die; the fixed block is formed on the clamp die installation plate and formed with a forked tail slot; the plug bush die is formed with a forked tail tenon; the forked tail tenon is plugged into the forked tail slot; and the plug bush die can be conveniently replaced so as to clamp different workpieces. When replacing the fixed clamp die, only the plug bush die needs to be replaced, and all the clamp parts do not need to be customized and replaced like the prior art.

Description

Work piece holder

Technical field:

The utility model relates to the clamp technology field, more specifically to the anchor clamps that use in a kind of machining.

Background technology:

As shown in Figure 1, existing anchor clamps by decide clamping 101, move clamping plate 102, clamping installing plate 103 is formed, decide clamping 101 and be fixed on the clamping installing plate 103, replacing is got up very inconvenient, and moving clamping plate 102 can be to deciding clamping 101 motions with clamping work pieces 104 under cylinder or hydraulic oil cylinder driving.Its weak point is: 1, generally speaking, during the various workpiece of machining, a kind ofly decide 101 of clampings and be suitable for and clamp a kind of workpiece 104, need the clamping 101 of deciding accordingly customized when process different workpiece 104, if go the supporting clamping 101 of deciding customized also to lose time when zero.2, be shaped to one owing to decide on clamping 101 and the clamping installing plate 103, change when decide clamping 101, move clamping plate 102 accordingly, clamping installing plate 103 all gets replacing customized, is very much inconvenient.

The utility model content:

The purpose of this utility model is exactly the deficiency at prior art, and a kind of work piece holder is provided, it decide clamping and can easily change to adapt to the needs that the processing different workpieces clamps.

Technology solution of the present utility model is as follows:

Work piece holder comprises and decides clamping, moving clamping plate and clamping installing plate, decides clamping and is made up of fixed block and sleeve mould, fixed block is molded on the clamping installing plate, form the dovetail slot on the fixed block, form the dovetail plug tenon on the sleeve mould, this dovetail plug tenon sleeve is in this dovetail slot.

Described screw rod passes prediction on the fixed block and establishes the hole and be screwed onto with the sleeve mould.

Dovetail slot on the described fixed block is the T-shape groove, and the dovetail plug tenon on the corresponding sleeve mould is the T-shape tenon.

The beneficial effects of the utility model are:

1, its sleeve mould can be changed easily to adapt to the clamping different workpieces.

2, change when deciding clamping, only need to change the sleeve mould, and needn't go the whole clamp member of replacing customized as prior art.

Fig. 3 is the structural representation of embodiment 2;

Fig. 4 is the schematic perspective view of embodiment 3;

Fig. 5 is the schematic perspective view of sleeve mould among the embodiment 4.

The specific embodiment:

Embodiment 1: see Fig. 2, work piece holder, comprise and decide clamping 1, moving clamping plate 2 and clamping installing plate 3, deciding clamping 1 is made up of fixed block 11 and sleeve mould 12, fixed block 11 is molded on the clamping installing plate 3, form dovetail slot 111 on the fixed block 11, form dovetail plug tenon 121 on the sleeve mould 12, these dovetail plug tenon 121 sleeves are in this dovetail slot 111.

Described screw rod 4 passes prediction on the fixed block 11 and establishes hole 112 and be screwed onto with sleeve mould 12.

Described sleeve mould 12 has middle bench 122.

Embodiment 2, see Fig. 3, the dovetail slot 111 on the described fixed block 11 is the T-shape groove, and the dovetail plug tenon 121 on the corresponding sleeve mould 12 is the T-shape tenon.All the other are with embodiment 1.

Embodiment 3, see Fig. 4, described sleeve mould 12 is a skewback.All the other are with embodiment 1.

Embodiment 4, see Fig. 5, and described sleeve mould 12 has step 122 and groove 123.All the other are with embodiment 1.
