Abstract

The utility model provides a novel caliper, comprising a graduated scale and a clamping board arranged at the center of the graduated scale, wherein the clamping board is connected on the graduated scale rotatably by a rotating shaft. The novel caliper can detect the planeness of core boxes with different inner cavity shapes so as to be convenient for inspection and calibration of a mold.

Description

A kind of novel slide calliper rule

Technical field

The utility model relates to a kind of novel slide calliper rule.

Background technology

In the process of castings production, need carry out a series of inspection to casting die, check its flatness.General columniform core box can be done a semicircle clamp from moving to down; Place explanation roundness blocking is not enough; But it is just inconvenient when taper core box as depicted in figs. 1 and 2 is checked; Because its inner chamber is taper, the semicircle radius of the xsect at each position is all different, can't use the semicircle clamp directly from moving to the flatness of inspection inner chamber.

Summary of the invention

The utility model technical matters to be solved is to provide a kind of novel slide calliper rule, can check its flatness to the difform core box of inner chamber, makes things convenient for the check and the calibration of mould.

For solving above-mentioned existing technical matters, the utility model adopts following scheme: a kind of novel slide calliper rule, and comprise rule, be located at the central clamp of rule, said clamp is transferred on rule through rotating shaft.

As preferably, the central authorities of said rule are provided with the center scale, and the both sides that are positioned at the center scale on the said rule are provided with the scale mark of symmetry.Be convenient to confirming of rule middle position.

As preferably, said clamp adopts irregularly shaped.

As preferably, said clamp adopts regular shape.

As preferably, said clamp adopts right-angled trapezium, and the right-angle side of right-angled trapezium is connected with rotating shaft.

Beneficial effect:

The utility model adopts technique scheme that a kind of novel slide calliper rule are provided, and can check its flatness to the difform core box of inner chamber, has made things convenient for the check and the calibration of mould.

Fig. 2 is the vertical view of taper core box;

Fig. 3 is the front view of the utility model;

Fig. 4 is the left view of the utility model.

Embodiment

Like Fig. 3 and shown in Figure 4, a kind of novel slide calliper rule comprise rule 1, are located at the clamp 2 of rule 1 central authorities, and said clamp 2 is transferred on rule 1 through rotating shaft 3.The central authorities of said rule 1 are provided with the center scale, and the both sides that are positioned at the center scale on the said rule 1 are provided with the scale mark of symmetry.Said clamp 2 adopts right-angled trapezium, and the right-angle side of right-angled trapezium is connected with rotating shaft 3.

During actual the use; The tangential direction of rule 1 along taper core box inner chamber semicircle lain in a horizontal plane on the taper core box, if scale both sides, center scale mark identical facing to the scale at taper core box edge, promptly confirm the center line of taper core box; Clamp 2 is rotated; If change motionless somewhere, then detect undesirable part, made things convenient for the check and the calibration of mould.Clamp 2 can be made according to the shape of the dies cavity that will detect, and can be irregularly shaped, also can be regular shape, can check its flatness to the difform core box of inner chamber, has made things convenient for the check and the calibration of mould.
