Description

Technical Field

[0001] This utility model relates to the field of steel ball detection, specifically an adjustable fixture for steel ball detection. Background Technology

[0002] Steel balls are metal products with a spherical structure, widely used in industrial fields. Their core functions include serving as a grinding medium (such as grinding materials in a ball mill) and a mechanical transmission component (such as rolling elements in bearings and universal joints). To facilitate the inspection of steel balls, a fixture is needed to limit their movement. The "Steel Ball Size Screening Fixture" disclosed in application number "CN202322335739.5" is an increasingly mature technology. This invention, through the setting of a guide component, transmission component, and screening component, can screen two sizes of steel balls, thus enhancing the versatility of the screening fixture. In use, several steel balls of two sizes are first placed on the screen plate inside the second screen frame. Then, the hydraulic cylinder is activated to lower the first screen frame. When the first screen frame contacts the steel balls, the bottom end of the first screen frame squeezes the steel balls. At this time, the larger steel balls are squeezed through the first screen hole and enter the interior of the first screen frame, while the smaller steel balls are squeezed through... The steel balls pass through the second sieve hole and enter the bottom of the second sieve frame, thus completing the sieving process. Compared to existing technologies that can only sieve steel balls of a single size, this invention can sieve two different sizes of steel balls through the above operation, thus enhancing the versatility of the screening fixture. However, this fixture still has the following drawbacks during use: While the fixture can indeed sieve steel balls through the combination of the first sieve frame, the second sieve frame, and the sieve plate, the structure is simple and not convenient for clamping steel balls of different sizes as needed. Therefore, it is necessary to provide a fixture that can easily clamp steel balls of different sizes and enhance versatility. In addition, existing fixtures are not convenient for disassembling and moving the components as needed. Therefore, it is necessary to provide a fixture that is easy to disassemble and assemble, easy to move, and improves ease of use. Utility Model Content

[0003] An embodiment of this utility model provides an adjustable fixture for steel ball detection, which aims to solve the problem that existing fixtures are not convenient for clamping and detecting steel balls of different sizes and for disassembling and assembling various components.

[0004] To achieve the above objectives, this utility model provides an adjustable fixture for steel ball detection, including a receiving component and a positioning component;

[0005] The receiving component includes a mounting platform, a storage bin slidably connected to one side of the mounting platform, and several casters mounted on the lower end of the mounting platform.

[0006] A positioning assembly includes a base plate mounted on the upper part of a mounting platform. A pressure plate is provided on the upper part of the base plate. Several positioning blocks are mounted in a rectangular array on the opposing surfaces of the base plate and the pressure plate. Lower clamping blocks are detachably mounted on the upper ends of the positioning blocks on the upper part of the base plate.

Several positioning holes are opened on the surface of the pressure plate, and several positioning rods are inserted into the positioning holes. A mounting ring is fixedly mounted on the upper part of the pressure plate, and a bearing is installed inside the mounting ring. The lower end of the lead screw is inserted into the bearing.

[0007] As a preferred embodiment of this utility model, the surface of the mounting platform is provided with two sliding grooves.

[0008] As a preferred embodiment of this utility model, a second screw hole is provided at the upper end of each of the positioning blocks, and bolts are fixedly connected to the surfaces of the lower clamping block and the upper clamping block, and the bolts are threaded into the interior of the second screw hole.

[0009] As a preferred embodiment of this utility model, the surface of the positioning block is provided with an annular groove, and the opposite sides of the lower clamping block and the upper clamping block are fixedly connected with positioning rings, which are engaged inside the annular groove.

[0010] As a preferred embodiment of this utility model, the upper end of the base plate is provided with a plurality of insertion holes, and the lower ends of the plurality of positioning rods are all fixedly connected with insertion rods, the insertion rods being inserted into the insertion holes.

[0040] Working principle: In use, the fixture can be moved by the mounting platform 101 and several self-locking casters 103 at the bottom. The storage bin 102 can be used to store replacement parts for later use. When in use, steel balls of different sizes can be placed in the arc-shaped grooves of the lower clamping blocks 204 at the top of several positioning blocks 203 as needed. At the same time, rotating the screw 209 clockwise or counterclockwise along the first screw hole 208 will raise and lower the pressure plate 202 along the gantry frame 207. When the pressure plate 202 lowers with the upper clamping block 205, it can clamp the smaller steel balls with the lower clamping block 204. When the pressure plate 202 rises along the gantry frame 207, it can clamp and limit the larger steel balls. Therefore, the versatility of the fixture can be significantly enhanced.
