Description

Technical Field

[0001] This invention belongs to the field of automated production fixture technology, and relates to a fixture for thin-walled parts in an automated production line. Background Technology

[0002] In the automated production and processing of parts, there are many regular parts (rectangular, circular). They can usually be clamped and processed using traditional clamping methods such as flat-jaw vises or three-jaw (four-jaw) chucks.

[0003] For special thin-walled workpieces, traditional tools cannot be used for clamping; only special fixtures can be used, which presents a problem of inconvenience in clamping.

[0004] For example, the fixture for thin-walled parts disclosed in announcement number CN216913520U has a simple structure, low manufacturing cost, can be manufactured by traditional machining, has no special processing steps, is easy to use, does not require high operator skills, and can achieve positioning and clamping by tightening fastening screws, ensuring the locking of clamping force and preventing workpiece deformation.

[0005] However, this device has low clamping efficiency and is inconvenient for clamping thin-walled parts during processing, which affects the processing efficiency of thin-walled parts.

[0006] Therefore, we urgently need to provide a fixture for thin-walled parts in an automated production line. Summary of the Invention

[0021] (III) Beneficial Effects

[0022] The automated production line thin-walled parts fixture provided by the above technical solution has the following beneficial effects:

[0023] 1. This automated production line's thin-walled parts clamping mechanism, through the setting of a clamping mechanism, involves placing the thin-walled parts on the outside of the lower and upper housings, and activating pump one to allow hydraulic oil to enter the mounting parts and hydraulic manifolds. This hydraulic oil pushes the push rod, causing the push block to move upward. Simultaneously, as the push block moves upward, it pushes the extension column to slide outward along the upper surface of the push block, thus clamping the inner support jaws one pair tightly against the inner wall of the thin-walled parts. At the same time, the hydraulic manifolds supply oil to push the inner support jaw two to slide outward along the limiting block and clamp against the inner wall of the thin-walled parts, thereby achieving the fixation of the thin-walled parts. This method has high clamping efficiency and facilitates the fixation of thin-walled parts.

[0024] 2. The thin-walled parts fixture of this automated production line is equipped with a filtration mechanism. The oil entering the hydraulic tank is filtered through a filter cover to prevent impurities in the hydraulic oil from affecting the tightness of the thin-walled parts.

[0025] 3. The thin-walled parts fixture of this automated production line is equipped with a cooling mechanism. During the flow of coolant through the outlet pipe, the coolant is cooled by heat dissipation fins, thereby realizing the recycling of coolant. Attached Figure Description

[0035] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0036] See Figures 1-8 The thin-walled parts fixture for the automated production line in this embodiment includes a base 1, and a clamping device is provided on the top of the base 1. The clamping device includes a clamping mechanism, a filtering mechanism and a cooling mechanism.

[0037] The clamping mechanism is located at the top of the base 1, the filtering mechanism is located on the right side of the base 1, and the cooling mechanism is located on the right side of the base 1.

[0038] The clamping mechanism includes a hydraulic tank 201, a pump body 202, a hydraulic main pipe 203, a return pipe 204, a lower housing 205, a mounting component 206, a push rod 207, a push block 208, an extension column 209, an inner support gripper 210, a bolt 211, an upper housing 212, a limit block 213, an inner support gripper 214, and a hydraulic branch pipe 215. The hydraulic tank 201 is mounted on the right side of the base 1, and the pump body 202 is mounted on the left front end of the hydraulic tank 201. One end of the hydraulic main pipe 203 is connected to the output end of the pump body 202, and the other end extends into the base 1. The return pipe 204 is connected to... On the right side of base 1, lower housing 205 is fixedly installed on top of base 1. Mounting component 206 is installed inside the lower end of lower housing 205. A guide hole is opened inside mounting component 206, and the guide hole is connected to hydraulic main pipe 203. Thin-walled part 5 is installed on the outside of lower housing 205 and upper housing 212. By fitting thin-walled part 5 onto the outside of lower housing 205 and upper housing 212 and starting pump body 202, hydraulic oil enters mounting component 206 and hydraulic branch pipe 215, thereby causing hydraulic oil to push push rod 207 to move push block 208 upward. As push block 208 moves upward, it pushes extension... The column 209 slides outward along the upper surface of the push block 208, causing the inner support claw 1 210 to tighten against the inner wall of the thin-walled part 5. At the same time, the hydraulic pipe 215 introduces oil to push the inner support claw 214 to slide outward along the limiting block 213 and tighten against the inner wall of the thin-walled part 5, thereby fixing the thin-walled part 5. The lower end of the push rod 207 is installed inside the upper end of the mounting part 206 and is located inside the lower housing 205. The push block 208 is installed on the top of the push rod 207 and is located inside the lower housing 205. The upper surface of the push block 208 has inclined grooves distributed at equal angles. One end of the extension column 209 is slidably connected to... The inclined chute inner wall can push the extension column 209 to move outward along the inclined chute when the push block 208 moves upward. One end of the extension column 209 is slidably connected to the top of the push block 208. The inner support claw 1 210 is installed at the other end of the extension column 209. The bolt 211 is threadedly connected to the inside of the extension column 209. The upper housing 212 is installed at the top of the lower housing 205. The limiting block 213 is installed at the upper end of the upper housing 212. The inner support claw 214 is installed at the top of the limiting block 213. One end of the hydraulic branch pipe 215 is connected to the hydraulic main pipe 203 and the other end is connected to one side of the hydraulic branch pipe 215.

[0039] The filtration mechanism includes a mounting block 301, a filter cover 302, a bracket 303, a spring 304, a baffle 305, a locking rod 306, and a pull rod 307. The mounting block 301 is fixedly installed on the left and right sides of the inner wall of the hydraulic tank 201. The front and rear sides of the filter cover 302 are slidably connected to the inside of the two mounting blocks 301. The end of the return pipe 204 away from the base 1 is connected to the hydraulic tank 201, and the return pipe 204 is located inside the filter cover 302. When the hydraulic oil flows back into the hydraulic tank 201 through the return pipe 204, the hydraulic oil is filtered by the filter cover 302, thereby preventing impurities in the hydraulic oil from affecting the tension of the thin-walled parts 5. The bracket 303 is fixedly installed on the upper end of the mounting block 301. On the side, one end of the spring 304 is fixedly installed on the inner wall of the bracket 303, the baffle 305 is fixedly installed on the other end of the spring 304, and the locking rod 306 is fixedly installed on the side of the baffle 305 away from the spring 304. The filter cover 302 has locking holes on the front and rear sides of the upper end, and the diameter of the locking holes is equal to the diameter of the locking rod 306. The end of the locking rod 306 away from the baffle 305 is hemispherical. After the front and rear ends of the filter cover 302 are engaged with the mounting block 301, the locking rod 306 is engaged with the locking holes of the filter cover 302, so as to facilitate the fixing of the filter cover 302 inside the hydraulic box 201. The pull rod 307 is fixedly installed on the side of the baffle 305 away from the locking rod 306 and extends to the outside of the bracket 303.

[0040] The cooling mechanism includes a cooling tank 401, a second pump body 402, an inlet pipe 403, a heat exchange pipe 404, an outlet pipe 405, and heat dissipation fins 406. The cooling tank 401 is installed on the right side of the hydraulic tank 201, and the second pump body 402 is installed on the front of the cooling tank 401. One end of the inlet pipe 403 is connected to the output end of the second pump body 402, the heat exchange pipe 404 is connected to the other end of the inlet pipe 403 and is located inside the hydraulic tank 201, and the outlet pipe 405 is connected to the heat exchange pipe 404 away from the inlet pipe 403. At one end, heat dissipation fins 406 are installed on the right side surface of the cooling box 401. The heat dissipation fins 406 are distributed on the right side of the cooling box 401 and the outer surface of the outlet pipe 405. The outlet pipe 405 is curved, and the end away from the heat exchange pipe 404 is connected to the cooling box 401. By setting the outlet pipe 405 to a curved shape, the flow distance of the coolant in the outlet pipe 405 is increased, thereby improving the heat exchange efficiency between the coolant and the outside, realizing the cooling of the coolant, and thus realizing the recycling of the coolant.

[0041] In use, the thin-walled part 5 is fitted onto the outside of the lower housing 205 and the upper housing 212, and the pump body 202 is started, allowing hydraulic oil to enter the mounting part 206 and the hydraulic manifold 215. When the hydraulic oil enters the mounting part 206, it pushes the push rod 207, causing the push block 208 to move upward. Simultaneously, as the push block 208 moves upward, it pushes the extension column 209 to slide outward along the upper surface of the push block 208, causing the inner support jaw 210 to tighten against the inner wall of the thin-walled part 5. At the same time, after the hydraulic oil enters the hydraulic manifold 215, the hydraulic manifold 215 pushes the inner support jaw 214 to slide outward along the limiting block 213, further tightening against the inner wall of the thin-walled part 5, thus fixing the thin-walled part 5 and improving the stability of the clamping. The hydraulic oil then flows along the return pipe 204... When the coolant flows back into the hydraulic tank 201, impurities in the hydraulic oil are filtered through the filter cover 302 to prevent them from affecting the opening of the inner support jaw 1 210 and inner support jaw 214. When the temperature of the hydraulic oil is too high, the pump body 2 402 is started to allow the coolant in the cooling tank 401 to flow into the heat exchange tube 404 through the inlet pipe 403. The coolant exchanges heat with the hydraulic oil through the heat exchange tube 404 to cool the hydraulic oil and prevent it from becoming too hot, which would reduce the viscosity of the hydraulic oil and affect the normal operation of the fixture. After heat exchange, the coolant flows back into the cooling tank 401 through the outlet pipe 405. As the coolant flows along the outlet pipe 405, it is cooled by the heat dissipation fins 406, thus realizing the recycling of the coolant.

[0042] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
