Abstract

The utility model discloses a limiting locating device comprising a bottom plate and a V-type block provided with a bar-shaped hole, wherein the bottom plate is provided with a sliding groove, the V-type block is connected with the sliding groove in a sliding mode, a locating pin penetrating through the bar-shaped hole is fixed on the bottom plate, a reset spring is arranged between the locating pin and the side wall of the bar-shaped hole, and the V-type face of the V-type block is rough. The limiting locating device overcomes the defects that a clamping plate in the prior art can only clamp workpieces of one size and a clamp is single in function. The improved locating device can machine the workpieces of different sizes and saves manufacturing cost of the clamp.

Description

A kind of positioner that can be spacing

Technical field

The utility model belongs to the positioning fixture of machining, particularly a kind of positioner that can be spacing.

Background technology

During machining, part to be processed profile, size are all different, usually all be at processing parts, make positioner separately, but it is similar to face external form, the workpiece that size is approximate, when also adopting this method, will seem there is no need waste material so to do, in the design of the clamping fixture head that such defective also embodies, the chuck work piece that also weares and teares easily simultaneously.

The utility model content

Technical problem to be solved in the utility model is the workpiece that can only clamp a kind of size at the prior art middle clamp plate, causes the single defective of anchor clamps purposes; Provide after a kind of improve can be spacing positioner, but the workpiece of clamping different size has been saved the cost of making anchor clamps.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of positioner that can be spacing, comprise base plate and the V-block that offers bar hole, base plate offers chute, V-block and chute are slidingly connected, be installed with the alignment pin that runs through bar hole on the described base plate, be provided with back-moving spring between alignment pin and the bar hole sidewall, the V-type face of described V-block is matsurface.

Operating process of the present utility model is as follows: use two such V-blocks, base plate is fixed on the installed surface, workpiece is positioned on two V-blocks, V-block is according to workpiece size, at mobile clamping range and the clamping work pieces adjusted automatically of chute; Can realize that V-block transferring clamping range to be because the bar hole of V-block and be opened between the alignment pin on the pedestal and be provided with spring automatically, V-block is subjected to piece-holder, begin mobile, spring makes V-block be subjected to an opposite power simultaneously, when workpiece arrives balance to the chucking power of V-block and spring to the power of workpiece, can make V-block clamp workpiece;

When needing to change another dimensioned part, get final product according to the above-mentioned steps operation.

The beneficial effect that the utlity model has: 1, be provided with back-moving spring between alignment pin and the bar hole sidewall, make the workpiece that V-block can the clamping different size, saved the material of making anchor clamps separately for a certain dimension workpiece, saved processing cost; 2, the V-type face of V-block is matsurface, and matsurface has improved V-block to the frictional force of the face contact of workpiece, make workpiece especially round piece can better be clamped on the V-block.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, the utility model is a kind of positioner that can be spacing, comprise base plate 1 and the V-block 2 that offers bar hole 5, base plate 1 offers chute 3, V-block 2 is slidingly connected with chute 3, be installed with the alignment pin 4 that runs through bar hole 5 on the base plate 1, be provided with back-moving spring 6 between alignment pin 4 and bar hole 5 sidewalls, the V-type face of V-block 2 is matsurface.

Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.

Claims

One kind can be spacing positioner, it is characterized in that: comprise base plate and the V-block that offers bar hole, base plate offers chute, and V-block and chute are slidingly connected, be installed with the alignment pin that runs through bar hole on the described base plate, be provided with back-moving spring between alignment pin and the bar hole sidewall; The V-type face of described V-block is matsurface.
