Abstract
The utility model provides a brake pad compression test positioning clamp, and provides a specific clamp. The brake pad compression test positioning clamp comprises at least one rectangular support frame and a handle, wherein a pair of positioning rods are respectively arranged in the support frame in transverse and longitudinal directions; the positioning rod is connected with the support frame through a positioning slide block and a lock screw at two ends; two positioning pins are arranged on upper side of one border of the support frame, and matched with grooves on a heating plate to realize accurate positioning; and the handle is connected with the support frame through a connecting rod. The brake pad compression test positioning clamp is simple and reasonable in structure, can be used for adjusting longitudinal and transverse sizes according to brake pads in different models, and has the characteristic of wide use range.
Description
Technical field
The utility model relates to the auxiliary clamp in a kind of experimental facilities, specifically a kind of brake block compression test positioning fixture.
Background technology
Automotive brake will carry out compression performance with brake block in research and development and production run tests, and this test is divided into two kinds of normal temperature compressed performance and compressive properties, generally adopts compression test to test.During test, brake block is placed on the heating plate, then loading head moves down, with certain defeating on brake block to measure its decrement.In practical operation, the process of putting into brake block is manual, brake block is placed on the middle, below of loading head by range estimation, owing to being range estimation, can not guarantee can both be placed on the middle, below of loading head at every turn, affects the accuracy of experimental measurement.In addition, when carrying out the compressive property test, the temperature of heating plate is put into and is taken out by hand brake block and have the danger of scalding up to 400 degrees centigrade.
The utility model content
Problem to be solved in the utility model provides a kind of safely, fast and accurately test fixture of location, and can be applicable to test the brake block of different model.
The technical scheme in the invention for solving the technical problem is: a kind of brake block compression test positioning fixture, at least comprise a support frame, support frame is rectangular, horizontal and vertical in described support frame arranges respectively a pair of backstay, and described backstay is by positioning sliding block and lock-screw and the support frame loose joint at two ends, frame upside at described support frame is provided with two register pins, and the groove on register pin and the heating plate matches, to realize accurate location;
A handle, described handle links together by connecting link and support frame.
Described support frame integral thickness is less than 10 millimeters.
As of the present utility model preferred, described handle is wooden handle, and connecting link and handle total length are greater than 200 millimeters.
As of the present utility model preferred, be carved with scale mark on the support frame, be used for the position of auxiliary vision-control backstay.
The beneficial effects of the utility model are: the utility model is simple and reasonable, can regulate vertical and horizontal size according to the brake block of different model, has the wide characteristics of usable range.
Description of drawings
Fig. 1 is stereographic map of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is the structural representation of support frame;
Fig. 4 is for using constitutional diagram;
Among the figure: 1 lock-screw, 2 support frames, 3 handles, 4 connecting links, 5 located lateral bars, 6 radius rods, 7 located lateral slide blocks, 8 register pins, 9 longitudinal register slide blocks, 10 brake blocks.
Embodiment
Such as Fig. 1～shown in Figure 4,
This compression test positioning fixture is comprised of support frame 2, handle 3, connecting link 4, located lateral bar 5, radius rod 6, located lateral slide block 7, register pin 8, longitudinal register slide block 9 and lock-screw 1.
Notching construction above the support frame 2 of rectangle can guarantee that located lateral slide block 7 and longitudinal register slide block 9 are mobile within the specific limits, thereby so that located lateral bar 5 and radius rod 6 can be fit to the brake block of different size, can regulate by the subscale mark mark in the process of regulating, the precision of adjusting is higher.The length of support frame 2 is according to the size design of testing machine heating plate, can guarantee just in time to be in the middle, below of compressing head when brake block is in support frame 2 centre positions and register pin 8 and is stuck in the heating plate groove.
The general thickness of support frame 2 is no more than 10 millimeters, like this design can the adequacy test machine inner narrow space, guarantee that its thickness is lower than the thickness of friction material on the brake block (if greater than the thickness of friction material, the pressure of compressing head will directly be pressed on the support frame).
Before testing, should be according to the brake block size that will test, adjust the position of located lateral bar 5, radius rod 6, make it clamp a little brake block (just fall down be advisable with the turnover fixture brake block), should keep the lateral reference line on brake block cross central line and the support frame 2 to overlap after the adjustment, vertical reference line on longitudinal centre line and the support frame overlaps, and then tightens lock-screw 1, and it is fixed.
During test, directly brake block 10 is placed in the space that located lateral bar 5 and radius rod 6 intersect to form, as shown in Figure 4.Then put anchor clamps into testing machine, register pin 8 is stuck in the groove of testing machine heating plate, begin test and get final product.After test is finished, take out anchor clamps, turnover fixture, brake block drops, and puts into another sheet again and tests.
Except the described technical characterictic of instructions, be the known technology of those skilled in the art.
