Description

Technical Field

[0001] The utility model relates to the technical field of asbestos-free brake pad inspection, in particular to a non-asbestos brake pad inspection knocker. Background Art

[0002] Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. Currently, they are mostly made of NAO organic materials, which have the advantages of low noise and little wear on the brake disc. Asbestos brake pads contain asbestos. Although they have the advantages of low cost, light weight, high strength and high temperature resistance, the dust generated by friction during the braking process contains nano-level heavy metal particles. Once inhaled by the human body, the heavy metals produced by asbestos are considered to be an important source of air pollution. In many countries, the production and use of asbestos brake pads are expressly prohibited. Currently, most of the brake pads used are non-asbestos brake pads, which do not contain any asbestos components.

[0003] After searching, the application with patent number 202223097235.6 discloses a brake pad technology field, especially an asbestos-free brake pad inspection knocker, including a workbench, and also including: a knocking mechanism, the knocking mechanism is fixed on the workbench, the knocking mechanism includes a linear motor, a first cylinder, a dual-axis motor, two rotating shafts, a plurality of elastic rods and a plurality of knocking balls, the linear motor is fixed on the workbench, the first cylinder is fixed on the slider of the linear motor, the dual-axis motor is fixed on the push rod of the first cylinder, the two rotating shafts are respectively fixed on the top of the two output shafts of the dual-axis motor, the plurality of elastic rods are evenly fixed on the two rotating shafts, and the plurality of knocking balls are respectively fixed on the plurality of elastic rods. When the utility model is in use, by controlling a plurality of knocking balls, a plurality of knocking balls are used to perform a multi-directional knocking inspection on two asbestos-free brake pads, thereby inspecting the hardness of the asbestos-free brake pads;

[0004] The above application document drives the elastic rod and the knocking ball to rotate through a dual-axis motor to knock on the brake pad on the bottom side. However, due to the gravity of the elastic rod and the knocking ball, they may expand outward due to the centrifugal force as the dual-axis motor rotates, thereby affecting the accuracy of the knocking point and further affecting the accuracy of subsequent test results.

[0005] Therefore, we propose an asbestos-free brake pad inspection tapper. Utility Model Content

A guiding groove 32 with the same inclination is opened on the guiding seat 31, and an electric cylinder seat 33 is fixedly installed on the guiding seat 31; among them, the inclined setting of the guiding seat 31 is convenient for adjusting the height of the knocking component 4 thereon and the contact position between the knocking ball 45 thereon and the asbestos-free brake pad, ensuring the subsequent knocking detection effect.

[0030] A support 42 is fixedly installed on the second motor 41. The support 42 is slidably sleeved in the guiding groove 32, and the bottom end of the output shaft of the electric cylinder seat 33 is fixedly connected to the support 42; among them, the setting of the support 42 is convenient for it to be driven by the electric cylinder seat 33 to slide obliquely in the guiding groove 32.

[0031] Embodiment 2:

[0032] The limiting component 2 includes a sliding groove 22 opened on the top surface of the workbench plate 1 and a first motor 21 fixedly installed on the side wall of the workbench plate 1; among them, the settings of the first motor 21 and the sliding groove 22 can provide a driving mechanism and a traveling route for limiting the asbestos-free brake pad.

[0033] The output shaft of the first motor 21 is fixedly connected to a lead screw column 23 located inside the sliding groove 22, and a sliding seat 24 is threadedly sleeved on the lead screw column 23; among them, the settings of the lead screw column 23 and the sliding seat 24 are convenient for the first motor 21 to drive it to rotate and adjust the lateral position of the sliding seat 24, so as to stably limit the asbestos-free brake pad through its outward expansion.
