Description

Technical Field

[0001] The utility model relates to the field of fixture installation equipment, in particular to a quick installation mechanism for a fixture. Background Art

[0002] A fixture is a simple tool used by industrial production enterprises to control various dimensions of products (such as hole diameters, spatial dimensions, etc.), improve production efficiency and control quality, and is suitable for products in mass production, such as auto parts, to replace professional measuring tools, such as smooth plug gauges, screw plug gauges, outside diameter calipers, etc.

[0003] The accuracy requirements for various parts of an aircraft are relatively high. Currently, the fixtures for detecting shaft parts of an aircraft usually involve a standard housing, and then the processed shaft parts are pressed into the shaft holes of the housing, thereby realizing efficient and rapid detection operations on the processing dimensions of the shaft parts. Most of the current fixtures rely on bolts to fix the fixing plate of the fixture on the detection table. This method requires repeated leveling operations during installation. At this time, the staff needs to repeatedly loosen the locking bolts, and when changing products for different fixtures, the operation is relatively troublesome, greatly reducing the portability of fixture installation and disassembly.

On both sides of the slide rail 201, sliders 202 with opposite thread pitches are slidably arranged. A bidirectional screw is threadedly connected between the two sliders 202. The middle of the bidirectional screw is a smooth rod, and both ends are threaded rods. A rotating handle 203 is arranged outside the bidirectional screw. A fixed block 300 is arranged on the smooth rod of the bidirectional screw. A through hole larger than the outer diameter of the bidirectional screw is opened on the fixed block 300. A telescopic push rod 301 is arranged on the upper part of the fixed block 300. The telescopic push rod 301 is an electric telescopic rod or a hydraulic telescopic rod. On the left and right sides of the upper part of the slide rail 201, chutes with the same length as the outer thread of the bidirectional screw are respectively arranged. The end of the output rod of the telescopic push rod 301 is provided with a support plate 302 for placing the fixture. A clamping assembly 400 is arranged on the inner side of each slider 202. In the present invention, by manually turning the rotating handle 203, the bidirectional screw can be driven to rotate together. Coupled with the threaded connection between the bidirectional screw and the two sliders 202, the opposite thread pitches of the two sliders 202, and the limiting and guiding effects of the slide rail 201 on the two sliders 202, the rotation of the bidirectional screw can drive the sliders 202 to drive the clamping assemblies 400 thereon to move towards each other, thereby realizing the clamping and fixing and release operations of the fixture, eliminating the need for staff to repeatedly tighten bolts, making product changeover more convenient, greatly improving the portability of fixture installation, disassembly and product changeover, and making the operation more convenient.

[0020] According to an embodiment of the present invention, as Figure 1 and Figure 2As shown, the clamping assembly 400 includes a wedge-shaped pressing plate 401 disposed inside the slider 202. A spring piece 402 is provided at the lower part of the wedge-shaped pressing plate 401. The vertical part of the spring piece 402 is fixedly arranged on the inner side wall of the slider 202. The inclined part of the spring piece 402 forms a 30-degree angle with the vertical part of the slider 202. A baffle 403 is provided outside the wedge-shaped pressing plate 401 of the slider 202 on one side. The utility model can perform a pressing and fixing operation on the arc-shaped rib ring on the outer side wall of the housing to be detected through the wedge-shaped pressing plate 401, and perform an elastic support and clamping operation on the outer side wall of the housing to be detected through the spring piece 402, ensuring the portability and stability of placing and clamping the housing to be detected, and making the operation more convenient.

[0021] According to another embodiment of the utility model, as Figure 1 and Figure 3 shown, a support block 404 is provided on the upper part of the slide rail 201 and inside one of the sliders 202.

[0022] A placement plate 500 with a height lower than that of the support block 404 is provided on the upper part of the slide rail 201 and inside the other slider 202. The utility model can realize support and fixation of the process table at the lower part of the housing to be detected through the placement plate 500, which is more convenient.

[0023] The usage method of the utility model:

[0024] First of all, it should be clear that the installation mechanism involved in the present utility model is mainly used for clamping and fixing engine accessory housing products, and detecting the shaft holes of the housing by means of a shaft. Taking the detection of the housing for installing bearings in aircraft accessories as an example, the usage method of the present utility model is elaborated in detail. When it is necessary to detect the shaft holes of the housing, first place the housing on the support plate 302 according to the shape of the housing, and start the output rod of the telescopic push rod 301 to extend or retract until the lower edge of the housing is directly above the arc-shaped groove. Then start the output rod of the telescopic push rod 301 to retract until the lower edge of the housing is placed in the arc-shaped groove. Then, manually turn the handle. By manually turning the rotating handle 203, the bidirectional screw can be driven to rotate together. Coupled with the threaded connection between the bidirectional screw and the two sliders 202, the opposite thread action of the two sliders 202, and the limiting and guiding action of the slide rail 201 on the two sliders 202, the rotation of the bidirectional screw can drive the sliders 202 to drive the clamping assembly 400 on them to move towards each other, thereby realizing the clamping and fixing operation of the inspection tool. When it is necessary to remove the housing after the detection is completed, reverse-turn the rotating handle 203 until the housing can be conveniently taken out. The present utility model can conveniently and quickly adjust the distance between the two clamping assemblies 400 through the cooperation of the synchronous spacing adjustment assembly, realizing the clamping, fixing and releasing operations of the inspection tool, without the need for the staff to repeatedly tighten the bolts, making the production change more convenient, greatly improving the portability of the installation, disassembly and production change of the inspection tool, and making the operation more convenient.

[0025] The above is the preferred implementation manner of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
