Description

Technical Field

[0001] The utility model relates to the technical field of automobile inspection tools, in particular to an automobile inspection tool centering adjustment device. Background Art

[0002] Gauges are simple tools used by industrial manufacturers to control the various dimensions of products, improve production efficiency and control quality. They are suitable for mass-produced products, such as auto parts, to replace professional measuring tools, such as smooth plug gauges, threaded plug gauges, outside diameter calipers, etc., and can quickly detect auto parts.

[0003] After searching, Chinese patent publication number CN116276699A discloses a centering adjustment device for automobile inspection fixtures, which relates to the technical field of automobile inspection fixtures and includes a device main body, wherein the device main body includes a slider, a clamping block, a push rod and a scale. Sliders are provided at both ends of the top of the device main body, hydraulic rods are installed at both ends of the slider, and clamping blocks are sleeved on the telescopic ends of the hydraulic rods. Four clamping blocks are provided, and air pumps are installed on one side of the four clamping blocks. A push rod is provided on one side of the clamping block. The bottom of the slider is welded to the top of the second connecting block, and one end of the second connecting block is rotatably connected to one end of the screw rod. During use, the device contacts the inspection fixture through multiple push rods, which is conducive to enabling the device to fully contact the inspection fixture for fixation, and then helps to prevent the inspection fixture from falling during centering adjustment, thereby affecting use.

[0004] However, in the above technical solution, only high-pressure gas is generated by the air pump to push the push rod to clamp and fix the automobile inspection fixture. Although the push rod can fit the automobile inspection fixture more closely to a certain extent, the ejection force on the push rod is the same. When the push rod contacts and clamps the weak part of the automobile inspection fixture, the ejection force of the push rod is too large, which can easily cause deformation of the automobile inspection fixture.
