Description

Cambered surface grinding head clamp for textile wear resistance test

Technical Field

The utility model belongs to the technical field of clamp manufacturing, and particularly relates to a grinding head.

Background

When the textile is subjected to wear resistance testing, the textile to be tested needs to be tightened and fixed on the grinding head clamp, then the friction piece with the specified roughness is used for repeatedly rubbing the textile to be tested, and finally the wear resistance testing result of the textile to be tested is obtained.

The textile fixture provided in the prior art often has a grinding head which is planar, for example, a wear resistance testing device disclosed in chinese patent application with a patent publication number of "CN 207557030U", wherein the textile fixture includes a connecting rod, a metal cover, a rubber pad, a press ring and a base, a triangular bolt is arranged at the bottom of the press ring, and a fine needle is not arranged at the outer edge of the press ring; the base is provided with a pin hole at the position corresponding to the triangular bolt.

When using above-mentioned testing arrangement to during concrete socks wear test experiment, operating personnel need the socks sample of awaiting measuring, then fix on the clamping ring. The compression ring and the base fix the sock fabric for sampling, the rubber pad is placed, and the metal cover is covered, so that the rubber pad has a certain thickness to form a protrusion, and the situation of wearing socks is simulated. Then, a connecting rod is inserted, and then a weight is pressed, and friction is carried out on the Martindale machine.

It should be noted that in the abrasion-proof testing device proposed in the above patent, the rubber pad thereof is in a chessman shape, and the grinding head which is tightly attached to the sock sample and supports the sock sample is in a plane, and such a grinding head shape is in a special structure in response to the textile testing sample which has a curved surface radian, such as the heel of the sock, the shoulder of the jacket, etc., because the grinding head which is in a plane is not well attached and clamped with the grinding head, the textile sample is easy to shift, stretch or deform during the testing process, and the accuracy of the abrasion-proof testing result of the textile sample is seriously affected.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, an object of the present invention is to provide a fixture having a grinding head insert with a curved surface, which is adaptable to a textile test sample with a curved surface radian and a special structure, and which facilitates tightening and loosening the textile test sample for displacement, so as to obtain a more accurate wear-resistant test result.

The utility model also aims to provide the cambered surface grinding head clamp for the wear resistance test of the textile, which has the advantages of simple structure, convenience in disassembly and assembly and stable and reliable clamping.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

the utility model provides an cambered surface bistrique anchor clamps for fabrics wear test, this anchor clamps are including:

a grinding head insert with an arc-shaped tightening surface for tightening the textile to be measured;

a clamp ring for fixing the grinding head insert;

the fixture connecting sleeve is used for compressing the grinding head embedded block and the compression ring;

the grinding head embedded block is matched with the inner wall of the pressing ring, and when the grinding head embedded block is correspondingly embedded into the pressing ring, the arc-shaped tightening surface of the grinding head embedded block extends out of the pressing ring; the clamp connecting sleeve covers the compression ring and is detachably connected with the compression ring, and when the clamp connecting sleeve is connected with the compression ring, the clamp connecting sleeve tightly presses the grinding head embedded block.

During the use, the fabrics cladding that operating personnel will await measuring is outside the bistrique abaculus, utilizes the arc taut face that has in the bistrique abaculus to tighten the appointed test site of fabrics that awaits measuring back, with bistrique abaculus embedding clamp ring to install the two on the anchor clamps nipple, keep the arc taut face in the bistrique abaculus to stretch out from clamp ring, can accomplish the equipment of the sample that awaits measuring.

Furthermore, the grinding head insert comprises a grinding head, a pressing part and an insert base; wherein, the grinding head is hemispherical, the embedded block base is cylindrical, and the compressing part is arranged between the grinding head and the embedded block base and is used for connecting the grinding head and the embedded block base; and the radius of the grinding head is smaller than that of the embedded block base, and the grinding head, the pressing part and the embedded block base are integrally connected.

Furthermore, the inner wall of the compression ring is matched with the compression part in shape and the embedded block base in arrangement. Furthermore, the outer wall of the compression ring is provided with an external thread.

Further, the clamp connecting sleeve comprises a clamp cover, and an inner thread matched with the compression ring is formed in the inner wall of the clamp cover; when the clamp cover is screwed on the compression ring, the clamp cover is abutted against the embedded block base.

Because the radius of bistrique is less than the radius of abaculus base, then the portion of compressing tightly that sets up between bistrique and abaculus base should present the annular connection face that has certain gradient, and correspondingly, because the inner wall shape of clamp ring cooperatees with portion of compressing tightly and abaculus base, then cover at anchor clamps and close on the clamp ring, the two is through the in-process of screwing gradually of the cooperation of internal and external screw thread, the bistrique abaculus is supported and is held by the anchor clamps lid, will compress tightly the inner wall of clamp ring gradually through the portion of compressing tightly, the structure that compresses tightly gradually like this can make things convenient for the technical staff to suitably adjust the process of screwing of screw thread according to the actual thickness degree of the fabric that awaits measuring, if the fabric sample that awaits measuring is thicker, then need not to screw the clamp lid to deepest position completely and can compress tightly the fabric sample, otherwise then need screw the clamp lid completely.

Further, the clamp connecting sleeve further comprises a clamp connecting column, and the clamp connecting column is arranged on the clamp cover and connected with the clamp cover in an integrated forming mode. In addition to abutting against the grinding head insert to cause it to compress the compression ring, the clamp coupling also serves to couple the overall clamp to an external mechanism: the anchor clamps flange is fixed in outside mechanism, then the anchor clamps lid also will be connected with outside mechanism, and operating personnel will await measuring textile fabric sample parcel before the experiment imbeds in the clamp ring behind the bistrique abaculus, twists the clamp ring again, links together its screwing and anchor clamps lid can install the fabrics that await measuring on the testing arrangement and begin the experiment, only need twist the clamp ring after accomplishing the experiment and can pull down it, whole process ten minutes convenient and fast.

The utility model has the advantages that: compared with the prior art, when the cambered surface grinding head clamp provided by the utility model is used for a textile wear resistance test, the cambered surface grinding head clamp can adapt to a textile test sample with a curved surface radian and a special structure, the textile is tightened and fixed, the textile is guaranteed not to be dislocated, not to be displaced and not to be stretched in the test process, the test is further helped to be stably carried out, and a more reliable test result is obtained.
