Description

Technical Field

[0001] This utility model relates to the technical field of material wear detection equipment, and in particular to a high-precision, high-load micro-motion wear detection sample fixing device. Background Technology

[0002] Fretting wear is a form of material damage that occurs when two contact surfaces undergo small-amplitude reciprocating motion under normal load. Accurate fretting wear performance testing of components is an important step in assessing service life and reliability, and the accuracy of the test results largely depends on the fixation and positioning accuracy of the test sample.

[0003] In the existing fretting wear testing process, the sample is usually fixed by manually locking it with traditional clamps using bolts and pressure plates. This process is not only cumbersome and time-consuming, but also makes it difficult to guarantee the uniformity and consistency of the clamping force. It relies on the operator's experience and directly affects the repeatability of the test conditions. When a large number of samples need to be tested, this inefficient manual clamping method becomes a bottleneck restricting the overall testing efficiency.

[0004] After the sample is clamped, it is also necessary to accurately align it with the friction pair or sensor on the detection stage. Existing technical solutions often separate the clamping unit from the adjustment unit. Operators need to manually adjust multiple sets of adjustment screws or move the entire clamping platform to perform alignment. This alignment process is also time-consuming and the accuracy is difficult to control. The clamping and adjustment steps are separated and inefficient. There is a lack of an integrated solution that can quickly and automatically clamp the sample and then perform high-precision two-dimensional adjustment.

[0005] Therefore, this invention proposes a high-precision, high-load micro-motion wear detection sample fixing device to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems existing in the high-precision, high-load fretting wear detection sample fixing equipment, such as cumbersome sample clamping and fixing process, low efficiency, and reliance on manual positioning and adjustment with difficulty in guaranteeing accuracy, this utility model aims to provide a high-precision, high-load fretting wear detection sample fixing equipment with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a high-precision, high-load micro-motion wear detection sample fixing device, including: a chassis, an adjustment mechanism, a testing table, and a clamping mechanism disposed inside the chassis.

[0008] The adjustment mechanism includes a sliding plate and a fixed slide rail. The bottom of the sliding plate is slidably connected to the slide rail via a second slide groove, and the chassis is slidably connected to the slide groove of the sliding plate via two sliders on both sides.

[0009] The clamping mechanism includes a motor, a rotating shaft, a locking shaft, a transmission disk, a rotating disk, a worm gear guide rail, a slider, a fixed block, and a push block. The output end of the motor is fixedly connected to the rotating shaft, and one end of the rotating shaft is fixedly connected to the locking shaft. The rotating disk is rotatably connected to the bottom of the inner wall of the machine housing. The transmission disk is fixed on the rotating disk, and the locking shaft meshes with the transmission disk. A worm gear guide rail is provided at the bottom of the transmission disk. A push block and a slider are meshed on the worm gear guide rail, and the fixed block is fixed to the bottom of the slider.

[0010] Preferably, there are two sliders, and the push block and the fixing block at the bottom of the two sliders form a circular array. Through this three-point clamping structure, the sample can be stably clamped and fixed with three claws, ensuring the concentricity and reliability of the clamping.

[0011] Preferably, the chuck is a drive gear, the outer periphery of the transmission disk is provided with a gear ring that meshes with the chuck, and the turbine guide rail is a planar thread on the bottom surface of the transmission disk. This combination of gear and planar thread transmission realizes the precise conversion from motor rotation to linear motion of the gripper.

[0012] Preferably, the second slider is fixed to the outer walls of both sides of the chassis, and the first slide groove is a guide groove vertically set on the inner side wall of the slide plate. This structure clarifies that the chassis is adjusted vertically to change the test height of the sample.

[0013] Preferably, the adjustment mechanism further includes a control console, which is electrically connected to a drive device for driving the chassis and the slide plate to slide. Through the operation interface of the control console, precise control of the vertical and horizontal position of the chassis can be achieved, thereby improving the level of automation.

[0014] Preferably, the adjustment mechanism further includes an indicator located at the bottom of the side adjacent to the slide plate, for displaying the vertical adjustment height data of the chassis in real time, providing the operator with an accurate height reference.

[0015] Preferably, the device further includes a corrector, which is fixedly mounted on one side of the chassis. The corrector can emit a visible laser onto the testing platform to visually identify the horizontal alignment of the chassis and the testing platform, thus ensuring the accuracy of the positioning.

[0016] Preferably, the motor is fixedly mounted on one side of the outer wall of the chassis, and the rotating shaft of the motor passes through the side wall of the chassis to drive the locking shaft inside the chassis. This external motor layout facilitates the installation, heat dissipation and maintenance of the motor.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting up a two-stage sliding adjustment mechanism consisting of a sliding plate and a sliding rail, and using an indicator and a laser corrector, solves the problems of low sample positioning accuracy, complex adjustment process and reliance on manual observation in the prior art. It can perform rapid and high-precision two-dimensional alignment adjustment of samples, improving the automation level and positioning reliability of the equipment.

[0019] 2. This utility model solves the problems of cumbersome and inefficient sample clamping and fixing process and difficulty in adapting to samples of different sizes in the prior art by setting a three-jaw clamping mechanism driven by a motor and transmitted through a clamping shaft, transmission disk and turbine guide rail. It can quickly and automatically clamp and fix the test samples, which is easy to operate and can be compatible with samples of various sizes, thus improving the efficiency of test preparation.

[0020] 3.

The rotating shaft 201 of motor 4 passes through the side wall of housing 1 and extends into the interior of housing 1 to drive the locking shaft 202 inside housing 1.

[0040] As another preferred embodiment, please refer to Figure 6 The adjustment mechanism 3 also includes a control console 307, which is electrically connected to a drive device for driving the chassis 1 and the slide plate 302 to achieve precise control of the vertical and horizontal position of the chassis 1.

[0043] Working principle: When sample positioning is required, the control console 307 drives the chassis 1 to slide vertically within the slide groove 303 of the slide plate 302 via the two sliders 301 on both sides to adjust the height of the chassis 1. During the adjustment process, the indicator 304 can display the vertical height data in real time. At the same time, the control console 307 drives the slide plate 302 to slide horizontally on the slide rail 305 via the two slide grooves 306 at the bottom to adjust the horizontal position of the chassis 1. During the adjustment process, the corrector 6 fixed on one side of the chassis 1 emits a visible laser to the detection stage 5 to assist in high-precision horizontal alignment. Through the vertical adjustment of the slide groove 303 and the horizontal adjustment of the slide groove 306, high-precision two-dimensional matching between the chassis 1 and the detection stage 5 is achieved.

[0044] When samples need to be clamped, the motor 4, which is fixed to the outer wall of one side of the chassis 1, is activated. The output end of the motor 4 drives the rotating shaft 201 to rotate. The rotating shaft 201 passes through the side wall of the chassis 1 and drives the clamping shaft 202, which is fixedly connected at one end, to rotate. Since the clamping shaft 202 meshes with the transmission disk 203, the rotation of the clamping shaft 202 will drive the transmission disk 203 to rotate. The transmission disk 203 is fixed on the rotating disk 204, which is rotatably connected to the bottom of the chassis 1. Therefore, the transmission disk 203 will drive the rotating disk 204 to rotate together. The turbine guide rail 205 set at the bottom of the transmission disk 203 will rotate accordingly and drive the push block 208, the two sliders 206, and the fixed block 207 at the bottom to move towards the center or open outward in sync through the meshing of the planar threads. Through this three-jaw linkage structure driven by the motor 4, the rapid and automatic clamping and fixing of samples of different sizes is realized.
