Description

TECHNICAL FIELD

[0001] The utility model relates to rack production and processing technical field, concretely is a kind of positioning mechanism of rack processing. BACKGROUND

[0002] Rack is the frame structure for supporting and fixing equipment, components and the like, and is widely used in many fields such as machinery and electronics. Racks are mainly made of steel, aluminum alloy, cast iron, engineering plastics, composite materials and other materials. Among them, aluminum alloy racks are mainly assembled into shape after cutting aluminum alloy profiles. They have the effects of convenient modular assembly, light weight, high strength, corrosion resistance and the like. During the cutting process, the cutting length needs to be ensured by a positioning mechanism.

[0003] When cutting aluminum profiles of the rack, the distance between the positioning mechanism and the cutting knife is usually measured by setting a scale gauge on the cutting machine. However, aluminum alloy profiles will generate debris during the cutting process, which can easily cover and even wear the gauge, thereby affecting the positioning effect. SUMMARY

[0004] Therefore, the utility model aims to provide a positioning mechanism for rack processing to solve the technical problems mentioned in the background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a positioning mechanism for rack processing, comprising a support, a baffle and a sealed shell are connected to one side of the outer surface and the back of the support, and a guide rail is connected inside each of the two baffles. A sliding carriage is connected to the bottom of each of the two guide rails, and a positioning plate is connected between the two sliding carriages. A first strong magnet is installed in the middle of the bottom of each of the two sliding carriages. A laser range finder is installed inside one side of each of the two sealed shells. A linkage block is connected inside each of the two sealed shells, and a second strong magnet is installed in the middle of the top of each of the two linkage blocks.

[0006] By adopting the above technical scheme, the worker slides the positioning plate, and the positioning plate is guided and supported by the sliding carriage and the inverted T-shaped guide rail during the sliding. The setting of the baffle prevents the falling aluminum alloy debris from falling on the contact surface of the sliding carriage and the guide rail, reduces the wear of the structure and prolongs the service life of the structure. The sliding carriage drives the first strong magnet to displace, and the second strong magnet is affected by the magnetic attraction of the first strong magnet to drive the linkage block to displace. At this time, the distance between the laser range finder and the linkage block is measured to measure the distance between one end of the aluminum alloy profile and the cutting blade. The laser range finder, linkage block and second strong magnet are surrounded by the sealed shell to avoid the aluminum alloy debris from blocking the laser range finder and increasing the wear of the linkage block.

[0007] Further, the guide rail section is inverted T-shaped, and the blocking frame section is n-shaped.

[0008] By adopting the above technical scheme, the staff slides the positioning plate, and the positioning plate is guided and supported by the sliding frame and the inverted T-shaped guide rail during the sliding process. The setting of the blocking frame prevents the falling aluminum alloy scraps from falling on the contact surface of the sliding frame and the guide rail, reduces the structural wear and tear, and prolongs the service life of the structure.

[0011] Further, the first strong magnet and the second strong magnet are both neodymium iron boron magnets.

[0012] By adopting the above technical scheme, the magnetic property of the neodymium iron boron magnet is strong. Even if there is a certain gap between the first strong magnet and the second strong magnet, the magnetic attraction of the first strong magnet can still drive the second strong magnet to displace.

[0013] Further, the linkage block is slidably connected with the sealing shell, and the linkage block is located directly below the sliding frame.

[0014] By adopting the above technical scheme, the sliding frame drives the first strong magnet to displace, so that the second strong magnet is affected by the magnetic attraction of the first strong magnet and drives the linkage block to displace. At this time, the distance between the laser range finder and the linkage block is measured, so that the distance between one end of the aluminum alloy profile and the cutting blade is measured.

[0015] Further, the top of the support is connected with a top frame, and the top of the top frame is provided with a first air cylinder. The output end of the first air cylinder is connected with a protective cover, and the side of the protective cover is provided with a motor. The output end of the motor is connected with a cutting blade. The top of the support is provided with four second air cylinders on both sides, and the output ends of the four second air cylinders are connected with clamping plates. The top of the two sliding frames is penetrated by a limiting bolt.

[0016] By adopting the technical scheme, after the position of the positioning plate is adjusted, the staff tightens the limiting bolt against the stop frame, and limits through friction, thereby reducing the phenomenon of random displacement of the positioning plate, then the staff pushes the aluminum alloy profile, and the cutting position of the aluminum alloy profile is limited as the aluminum alloy profile is displaced to abut against the positioning plate; then the staff starts the first air cylinder, the motor and the second air cylinder; after the second air cylinder is started, the output end drives the clamping plate to displace towards the aluminum alloy profile, thereby clamping the aluminum alloy profile; after the motor is started, the output end drives the cutting piece to rotate, after the first air cylinder is started, the output end drives the protective cover, the motor and the cutting piece to move downwards, and the cutting piece moves downwards in the rotating process, thereby cutting the aluminum alloy profile into two parts, so as to be used for assembling a production rack subsequently.

[0017] Further, the support is internally connected with a plurality of rollers, and the plurality of rollers are equidistantly distributed.

[0018] By adopting the technical scheme, the staff places the aluminum alloy profile on the rollers, then pushes the aluminum alloy profile, and reduces the frictional resistance when the aluminum alloy profile translates through the rotation of the rollers.

[0019] Further, the slide is connected with brushes on both sides of the bottom, and the brushes are in the shape of a Chinese character "kou".

[0020] By adopting the technical scheme, the shape of the brush can surround the first strong magnet, thereby sweeping away the aluminum alloy scraps around the first strong magnet, so as to reduce the abrasion phenomenon.

[0021] Further, the brush is in contact with the top of the sealing shell.

[0022] By adopting the technical scheme, the displacement of the slide also drives the displacement of the brush, thereby sweeping away the scraps on the top of the sealing shell, and reducing the abrasion of the first strong magnet.

[0023] Further, the linkage block is made of polytetrafluoroethylene material.
