Description

Technical Field

[0001] The utility model relates to the technical field of brake pad detection equipment, in particular to a brake pad strength detection device. Background Art

[0002] Brake pads, also called brake pads, are the most critical safety parts in the car's braking system. The quality of all braking effects is determined by the brake pads.

[0003] At present, after the production of brake pads, it is often necessary to perform various tests on the finished brake pads, such as the content disclosed in the utility model patent with publication number CN214952763U, which is named a test device for facilitating the detection of impact strength of brake pads. The device includes a base, a groove, a bearing plate and a pressure sensor. The upper end of the base is provided with the groove, the bearing plate is provided in the groove, the upper end of the bearing plate is provided with a limiting groove, the bottom end of the bearing plate is provided with the pressure sensor, a telescopic column is provided on one side of the upper end of the base, a connecting plate is provided on the top of the telescopic column, an operation panel is provided on one side wall of the telescopic column, a display screen is provided on the operation panel, and an electromagnetic suction cup is provided at the bottom end of the connecting plate.

[0004] When in use, the above-mentioned device can only detect the magnitude of the value transmitted by the impact force of the steel ball on the brake pad sample through the pressure sensor, and cannot detect the overall strength of the sample, and cannot achieve the purpose of strength detection. The existing strength detection device needs to adjust the height of the clamping part for different batches of samples. Each adjustment requires the clamping part to be disassembled and replaced with a gasket or block. This method is not only troublesome but may also cause repeated disassembly and replacement problems, affecting the detection efficiency of the sample. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a brake pad strength testing device for solving the technical problem in the background art that the existing testing device is difficult to adjust the height of the clamping block when testing samples of different batches.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A brake pad strength testing device comprises a base and a mounting plate, wherein the mounting plate is fixedly mounted on the base, a connecting frame is provided on the mounting plate, a dial with a scale is fixedly mounted on the side wall of the connecting frame, a mounting block is provided on the base, a clamping block for clamping a sample is provided for vertical sliding inside the mounting block, a height adjustment assembly for driving the clamping block to slide inside the mounting block is provided on the base, a swinging piece for testing the strength of the sample is provided on the connecting frame, a pointer is provided for rotating at the axis center of one side of the dial with the scale, and the rotation of the swinging piece drives the pointer to rotate.

[0008] Working principle:

[0009] This device is a brake pad strength testing device, which is mainly used to test the strength of brake pad samples.

[0010] When in use, the brake pad sample is mounted on the clamping block, and then the height adjustment component is operated to adjust the height of the clamping block so that the sample on the clamping block can be effectively impacted by the swinging member.

[0011] After the installation is completed, the test can be started. During the test, the oscillating piece is lowered from a high place. The oscillating piece moves towards the sample due to inertia, and the sample is broken by the impact. When the oscillating piece contacts the sample, it will also drive the pointer on the dial to rotate. The greater the strength of the sample, the greater the resistance the oscillating piece receives, and the smaller the distance the pointer moves.

[0012] Beneficial effects obtained:

[0013] First, a height adjustment component is provided to effectively adjust the height of the clamping block used to clamp the sample, so that the clamping block can be effectively impacted by the swinging piece after clamping samples of different batch sizes.

[0014] Secondly, it is equipped with an oscillating piece, which can effectively collide with the sample and break the sample, thus facilitating the subsequent detection and statistics of the sample strength. The pointer on the dial is driven to rotate, thereby recording the strength of the sample.

[0015] Third, a dial and a pointer are provided, which can effectively record the strength of the sample through the scale on the dial by rotating the pointer. BRIEF DESCRIPTION OF THE DRAWINGS
