Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, specifically to a measuring instrument for measuring the thickness of the coating in the inner bore of a hydraulic cylinder. Background Technology

[0002] "Hydraulic cylinder inner bore coating" refers to a functional coating formed on the inner wall of the hydraulic cylinder barrel (i.e., the inner bore, the mating surface of the piston reciprocating motion) through surface treatment processes such as electroplating, chemical plating, and thermal spraying.

[0003] A search revealed Chinese Patent Publication No. CN 221280190 U, published on July 5, 2024, which discloses a coating thickness measuring instrument. The document describes a "base with a bracket fixedly connected to it; two clamping plates are slidably arranged on the base, and the device to be measured is located between the two clamping plates; a fixing plate is fixedly arranged inside the bracket." This instrument has defects such as insufficient internal hole positioning accuracy, brittle coatings being easily damaged by rigid clamping, and lack of multi-dimensional detection capability in the entire circumference. In view of these defects, this case was developed after in-depth research. Utility Model Content

[0007] Preferably, the processing device further includes a pressing plate and a laser. The pressing plate is installed on the outer wall of the fixed column, and the laser is installed in the middle position of the pressing plate. The electric cylinder and the storage box are arranged perpendicularly to each other, and the bidirectional threaded rod is rotatably connected to the rotating shaft.

[0008] Preferably, the output end of the servo motor is fixedly connected to the right side of the bidirectional threaded rod, and the bidirectional threaded rod is threadedly connected to the threaded cap.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] By incorporating an electric cylinder, a storage tank, and a bidirectional threaded rod, the user places the coated part on the worktable, activates the servo motor, and drives the bidirectional threaded rod to rotate around the shaft. The threaded engagement between the bidirectional threaded rod and the threaded cap causes the fixing post to slide along the first groove. A push plate then presses the part to the center of the worktable and secures it. The electric cylinder is then activated, causing the storage tank to move downwards, allowing the pressing plate to further secure the top of the part. Simultaneously, the push plate, via the fixing rod, drives the connecting plate to slide along the second groove, compressing the telescopic spring in the first fixing groove to buffer collisions. Finally, a laser is used to measure the thickness of the coating on the secured part, ensuring measurement accuracy and stability and improving the device's operational quality.
