The flat ejector pin jig comprises a base, a first clamping part and a second clamping part, the first clamping part can be slidingly connected with the base, the second clamping part can be slidingly connected with the base, and the sliding track of the first clamping part is vertical to the sliding track of the second clamping part. With the flat ejector pin jig disclosed by the utility model, the five degrees of freedom of the flat ejector pin can be fixed in two directions through the first clamping part and the second clamping part, and the complete positioning can be realized. Therefore, with the flat ejector pin jig, the seamed edge of the flat ejector pin can be machined with a machine tool, and the working efficiency and product precision can be improved.

Description

A kind of flat thimble anchor clamps

Technical field

The utility model relates to a kind of jig, relates in particular to a kind of flat thimble anchor clamps.

Background technology

In the production process of mould of plastics, in order product to be ejected common employing thimble.When needs applied the die part that ejects active force and are rib, the thimble that is adopted was called flat thimble.In theory, flat thimble is the right angle with the side of the bullport of the flat thimble of guiding, and forms matched in clearance each other.But after flat thimble is machining described in the actual application, be easy to guarantee that side is the right angle, but, accomplish that inner side edge is that the right angle almost is impossible for bullport.Because be casting, pressure processing or machined all can form certain fillet in the inboard, its radius is generally 0.1mm.In order to realize the cooperation of said guide hole and flat thimble, must four seamed edges of said flat thimble also be processed into corresponding fillet.In the prior art, we are generally in filing by hand.As everyone knows, the efficient of manual processing is low, error is big.And this error can cause flat thimble to wander off, even the flat thimble that fractures.Between this, prior art has further improved needs.

The utility model content

The technical problem that the utility model will solve is to provide a kind of flat thimble anchor clamps, can be implemented in the flat thimble of processing on the lathe, improves the precision of flat thimble.

For solving the problems of the technologies described above, the utility model adopts following technical proposals.

A kind of flat thimble anchor clamps; Comprise that base, first adds the portion of holding, second and adds the portion of holding; Said first adds the portion of holding slidably is connected on the base, and said second adds the portion of holding slidably is connected on the base, and said first adds the track that the portion of holding slides adds the track that the portion of holding slides perpendicular to second.This flat thimble of the utility model adds the portion of holding and second through first and adds the portion of holding from its five frees degree of both direction limit, and realizes location fully.Thereby make said flat thimble can on lathe, process seamed edge, improve working (machining) efficiency and product precision, and then the goal of the invention of the utility model is able to solve.

Be preferable over: said second adds the portion of holding comprises Connection Block and push rod, and said push rod slidably is arranged on the Connection Block, and said push rod is parallel to first at the track that slides on the Connection Block and adds the track that the portion of holding slides on base.Through the active position of the mobile change push rod of push rod on Connection Block, improved adaptive capacity to the flat thimble in different sizes and cross section at flat thimble.

Be preferable over: said base comprises a bar-shaped trough, and the length direction of said bar-shaped trough adds the track and second that the portion of holding slides perpendicular to first simultaneously and adds the track that the portion of holding slides.Because what mould had that degree of precision requires to flat thimble cross section fillet is the rearward end about 3 to 5mm of flat thimble.Therefore, can flat thimble rearward end be defined in below the machined surface, make that processing is convenient through said bar-shaped trough.

The beneficial effect of the utility model is: this flat thimble anchor clamps can be realized location and clamping to flat thimble, make flat thimble on lathe, to process, and then improve the product precision.

The part description of reference numerals: base 1, bar-shaped trough 11, first add the portion of holding 2, second and add the portion of holding 3, Connection Block 31, push rod 32, flat thimble 4, leading section 41, rearward end 42.

The specific embodiment

Below in conjunction with accompanying drawing the described flat thimble anchor clamps of the utility model are done further detailed description.

This flat thimble anchor clamps referring to figs. 1 through Fig. 5 the utility model; Comprise that base 1, first adds the portion of holding 2, second and adds the portion of holding 3; Said first adds the portion of holding 2 slidably is connected on the base 1; Said second adds the portion of holding 3 slidably is connected on the base 1, and said first adds the track that the portion of holding 2 slides adds the track that the portion of holding 3 slides perpendicular to second.With reference to Fig. 4, said first adds the portion of holding 2 and second adds the portion of holding 3 and is fixed on the base 1 from both sides with flat thimble 4, and each side all is that the plane adds and holds.This structure makes flat thimble 4 except perpendicular to the moving on the direction on plane, drawing place, and moving and rotating on other directions all is limited.Location fully through clamp realizing flat thimble 4 is to satisfy mach needs at last.

Need to prove that the utility model provides and a kind ofly is used to add the anchor clamps of holding flat thimble, and the concrete lathe of processing flat thimble is had no particular limits, and can be that plain-milling machine also can be Digit Control Machine Tool or building-block machine.

As preferably, said second adds the portion of holding 3 comprises Connection Block 31 and push rod 32, and said push rod 32 slidably is arranged on the Connection Block 31, and said push rod 32 is parallel to first at the track of the slip on the Connection Block 31 and adds the track that the portion of holding 2 slides on base 1.Said push rod 32 can be fixed different positions as required, and simultaneously, this push rod also can be changed according to actual needs.

With reference to Fig. 1, Fig. 2, said base 1 comprises a bar-shaped trough 11, and the length direction of said bar-shaped trough 11 adds the track and second that the portion of holding 2 slides perpendicular to first simultaneously and adds the track that the portion of holding 3 slides.Though machine tooling yield rate and production efficiency all than higher, owing to it is had relatively high expectations to production lot and working environment, and need bigger early investment.Simultaneously because the fillet precision of flat thimble 4 the part that be its leading section 41 with mould directly mutually act on bigger to its performance impact.From Eco-power angle; We can adopt this flat thimble anchor clamps to process the leading section 41 of flat thimble; And rearward end 42 is arranged in the said bar-shaped trough 11, and rearward end 42 can directly be accomplished with pincers worker after machined is accomplished, and can further improve labor productivity like this.

The above is merely the specific embodiment of the utility model.But the utility model protection domain is not limited thereto.Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement; All should be encompassed within the protection domain of the utility model, therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
