The sliding plates of the clamping fixture can slide up and down, and the clamping block and the first arm plate can be used for clamping and fixing the ejector pins with different lengths, so that the clamping fixture can be used for clamping and machining the ejector pins with different lengths easily, the production efficiency of the ejector pins is improved, and the production cycle of a die is shortened.

Description

A kind of clamping jig

Technical field

The utility model belongs to the Machining Technology field, relates in particular to a kind of clamping jig.

Background technology

Along with scientific and technological progress, all can have a large amount of new product releases every year, and the production of new product (especially plastic cement products) needs corresponding mfg. moulding die, produces new product with mould.When mfg. moulding die, need to make a large amount of thimbles, due to the general sample different in size of thimble, with the bad clamping of existing clamping jig and processing, the production efficiency of thimble is very low, and then has affected the production cycle of mould.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of clamping jig of being convenient to clamping and processing is provided.

the utility model is to realize like this, a kind of clamping jig, the clamping that is used for thimble, comprise a base plate and and the location-plate that be fixedly connected with vertical with described base plate, have an opening up chute on described location-plate, be provided with a sliding panel that can relatively described chute slides up and down in described chute, described sliding panel top convex is provided with one first arm plate and one second arm plate, described the first arm plate and the second arm plate are parallel to each other and be positioned at the same side of described sliding panel, described the first arm plate inboard offers at least one V-shaped groove be used to placing described thimble, be equipped with a screw rod on described the second arm plate, described screw rod outer end is fixedly connected with one handle, described screw rod is inner to be fixedly connected with a clamp.

Particularly, described location-plate centre position offers a plurality of screws, be respectively equipped with a bolt in each described screw, described sliding panel centre position offers a strip gain that vertically arranges, described gain and described screw are oppositely arranged, and described bolt passes described chute is connected with gain and is connected with a nut.

Particularly, the width of described gain is than the large 0.2 ~ 1mm of diameter of described bolt.

Particularly, the width of described chute is than the large 0.01 ~ 0.03mm of width of described sliding panel.

Particularly, described screw rod is threaded with described the second arm plate.

Because the sliding panel of clamping jig of the present utility model can slide up and down, clamp and the first arm plate can grip the thimble of different length, therefore, for thimble different in size, the easy clamping of the utility model and processing, improve the production efficiency of thimble, shortened the production cycle of mould.

The specific embodiment

as shown in Fig. 1 ~ 5, a kind of clamping jig that the utility model embodiment provides, the clamping that is used for the thimble (not shown), comprise a base plate 1 and and the location-plate 2 that be fixedly connected with vertical with base plate 1, have an opening up chute 21 on location-plate 2, be provided with the sliding panel 3 that slides up and down of chute 21 relatively in chute 21, sliding panel 3 top convexes are provided with one first arm plate 31 and one second arm plate 32, the first arm plate 31 and the second arm plate 32 are parallel to each other and be positioned at the same side of sliding panel 3, the first arm plate 31 inboards offer at least one V-shaped groove 33 for placing thimble, be equipped with a screw rod 4 on the second arm plate 32, screw rod 4 outer ends are fixedly connected with one handle 5, screw rod 4 is inner to be fixedly connected with a clamp 6.

Slide up and down in the chute 21 of sliding panel 3 of the present utility model by location-plate 2, can adjust to the height corresponding with thimble to sliding panel 3, use again hand turning handle 5, handle 5 drives clamp 6 by screw rod 4 and is moved to the left, clamp 6 and the first arm plate 31 can with the thimble clamping and positioning that is contained in V-shaped groove 33, just can have been processed to thimble (as processing such as grinding, cut-outs).

Compare with existing clamping jig, because the sliding panel 3 of clamping jig of the present utility model can slide up and down, clamp 6 and the first arm plate 31 can grip the thimble of different length, therefore, for thimble different in size, the easy clamping of the utility model and processing have improved the production efficiency of thimble, have shortened the production cycle of mould.

Particularly, described location-plate 2 centre positions offer a plurality of screws 22, be respectively equipped with a bolt (not shown) in each screw 22, sliding panel 3 centre positions offer a strip gain 34 that vertically arranges, gain 34 is oppositely arranged with screw 22, and bolt passes that chute 21 is connected with gain and is connected with a nut (not shown).When needs are regulated the height of sliding panel 3, at first unclamp the nut on bolt, make between sliding panel 3 and location-plate 2 and unclamp, then up-down adjustment sliding panel 3 is to required height, follow the nut check on bolt, thereby realize sliding panel 3 is fixed on required height.The utility model can be realized the height of quick adjustment sliding panel 3, and is simple in structure, significantly improved working (machining) efficiency.

Particularly, the width of described gain 34 is than the large 0.2 ~ 1mm of diameter of bolt, so that bolt passes gain 34.

Particularly, the width of described chute 21 is than the large 0.01 ~ 0.03mm of width of sliding panel 3, so that sliding panel 3 can not swing on both sides at the interior Stable sliding of chute 21, guarantees the perpendicularity of sliding panel 3.

Particularly, be threaded between described screw rod 4 and the second arm plate 32, be convenient to adjusting screw(rod) 4 to the left or to the right.
