Description

A kind of fixture for machining

Technical field

The utility model relates to field of fixtures, more particularly, to a kind of fixture for machining.

Background technique

Fixture be machining must cannot tool, the main clamping for realizing blank and positioning enable process tool It is accurate to realize processing dimension.But existing fixture mainly clamps columnar member and square piece, but if clamp irregular blank It then has difficulties, especially the slightly larger blank of size, the fixture of original lathe is difficult with more, so with regard to needing to set It is stronger and the fixture of installation can be dismantled at any time to count a kind of versatility；It is at present that two sides can exert a force clamping there are also a kind of fixture, But for certain if cross sectional shape is the blank of triangle, clamping sides are depended alone with regard to relatively difficult, at least three directions force Just it is able to achieve clamping.

Utility model content

To solve the above-mentioned problems, the utility model proposes a kind of fixture for machining, three faces may be implemented Clamping can dismantle at any time simultaneously, and the occasion of blank can not be clamped by being suitable for original machine bed.

To achieve the goals above, the utility model adopts the following technical solution: a kind of fixture for machining, institute Stating fixture includes shell block, and installation both ends are fixed and the vertical upper sliding rail and glidepath with shell block two sides on the inside of shell block, upper sliding rail and It is fitted with left baffle and right baffle between glidepath, there is the substrate being fixed on shell block between lower guideway；The shell block two Side, which penetrates through and is equipped with side perpendicular to shell block, squeezes stud, and the shell block has the internal screw thread that the cooperation of stud external screw thread is squeezed with side； Perforation is equipped with extruding stud on the upside of the shell block, and the shell block has and the upper internal screw thread for squeezing the cooperation of stud external screw thread；Institute Shell block bottom is stated equipped with 4 or more symmetrical bolts hole.

Further, the upper sliding rail and glidepath respectively have two, and respective two sliding rails all about shell block side to Under center line it is symmetrical.

Further, lower end is fixed with sliding block in the left baffle and right baffle, and upper sliding rail and glidepath all pass through cunning The perforation of block.

Further, lubrication hole is provided on the sliding block.

Further, the side, which squeezes at the top of stud and upper extruding stud, the labour-saving arm of force.

Further, the side squeezes stud installation site at the center of left baffle and right baffle.

Further, there is limited block in the lower guideway middle position.

Further, the right baffle-plate right lateral surface, right shell body left-hand face and pedestal upper surface have anti-skid structure.

Compared with prior art, the utility model has the beneficial effects that:

1. the force in three directions clamps, the clamping of the irregular blank in section may be implemented；

2. can dismantle at any time, to make up, blank is excessive or occasion irregular and that original machine bed can not clamp.

Specific embodiment

For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention Specific embodiment of the present utility model, but the protection scope of the utility model be not limited to it is as described below.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model provides a kind of fixture for machining, the folder Tool includes shell block 1, and installation both ends are fixed and the vertical upper sliding rail 6 and glidepath 4 with 1 two sides of shell block on the inside of shell block 1, upper sliding rail 6 It is fitted with right baffle-plate 3 and right shell body 5 between glidepath 4, there is the substrate 10 being fixed on shell block 1 between lower guideway 4；Institute It states the perforation of 1 two sides of shell block and side is installed perpendicular to shell block 1 and squeeze stud 2, the shell block 1, which has, squeezes 2 external screw thread of stud with side The internal screw thread of cooperation；Perforation, which is equipped with, on the upside of the shell block 1 squeezes stud 7, and the shell block 1 has and the outer spiral shell of upper extruding stud 7 The internal screw thread of line cooperation；1 bottom of shell block is equipped with 4 or more symmetrical bolts hole 9, can dismantle at any time used in other The occasion for needing to position.

Preferably, the upper sliding rail 6 and glidepath 4 respectively have two, and respective two sliding rails all about 1 side of shell block to Under center line it is symmetrical.

As shown in Figure 5, it is preferable that lower end is fixed with sliding block 11 on the right baffle-plate 3 and right shell body 5, and upper sliding rail 6 is under Sliding rail 4 all passes through the perforation of sliding block 11.

As shown in Figure 6, it is preferable that be provided with lubrication hole 12 on the sliding block 11, keep the lubrication between sliding block and guide rail.

As shown in Figure 7, it is preferable that the side, which squeezes stud 2 and the upper top for squeezing stud 7, the labour-saving arm of force 14, general The clamping to blank 13 can be realized in logical worker.

As illustrated in fig. 1, it is preferred that the side squeezes 2 installation site of stud at the center of right baffle-plate 3 and right shell body 5, side is squeezed Press stud 2 to the thrust-neutral of left baffle.

As shown in Figure 3, it is preferable that there is limited block 8 in 4 middle position of lower guideway, and right baffle-plate 3 can only be in lower guideway 4 The left side, right shell body 5 can only be on 4 the right of lower guideway.

As illustrated in fig. 1, it is preferred that 3 right lateral surface of right baffle-plate, 5 left-hand face of right shell body and 10 upper surface of pedestal have Anti-skid structure prevents in process vibration to allow blank 13 dislocations.

With reference to Fig. 8, the fixture uses step:

Right baffle-plate 3, right shell body 5 and upper extruding stud 7, which are adjusted, arrives releasing orientation, blank 13 is put into, according to hair when putting The cross sectional shape selection of base 13 clamps disposing way, and adjusting side extruding stud 2 makes right baffle-plate 3 and right shell body 5 compress 13 side of blank Face, then adjust and squeeze 7 extrusion blank of stud, 13 upside, reach the function of clamping blank 13.

It can be concluded that the force that three directions may be implemented in the fixture clamps, the irregular hair in section may be implemented The clamping of blank；It can dismantle at any time, the occasion that original machine bed can not clamp to make up that blank is excessive or irregular.

Disclosed above be only the preferred embodiment of the utility model, cannot limit the utility model certainly with this Interest field, therefore according to the utility model claims make ground equivalent variations, still fall within the scope of the utility model.
