Description

Technical Field

[0001] The utility model relates to the technical field of bushing processing, in particular to a high-precision automobile bushing stamping processing device. Background Art

[0002] A bushing is a device used to support and protect mechanical parts, usually made of metal, plastic or rubber. It is usually installed in a hole or groove to reduce friction, wear and vibration, thereby improving the efficiency and life of the machinery. Bushings are usually used in sliding or rolling contact situations, such as bearings, guides, chains, etc.

[0003] The utility model patent with the existing patent publication number CN214348922U discloses a bushing stamping processing device, including a frame, a push rod motor is fixedly installed in the middle of the upper surface of the frame, a lower die is placed at the bottom of the transmission shaft of the push rod motor, the lower die is clamped in the die sleeve, a bolt is passed through the front wall of the die sleeve, and the bolt is screwed with the screw hole preset in the front wall of the upper die through a thread, the top of the die sleeve is connected to the transmission shaft of the push rod motor, and concave platforms are provided on both sides of the upper surface of the frame, and convex strips are clamped in the concave platforms. The utility model is provided with a pressing plate and a convex strip. During the assembly of the lower die, the convex strip of the lower die can be clamped by the concave platform to limit the horizontal position of the lower die, and the limiting groove of the pressing plate can be clamped on the outside of the lower die to limit the vertical horizontal position of the lower die, thereby ensuring the stability of the fixation of the lower die, and compared with the existing multiple sets of screw fixing methods, the disassembly and replacement of the lower die is more convenient.

[0004] After analysis, it was found that although the device can drive the pressure plate to move horizontally by rotating the screw, and then adjust the distance between the pressure plates for processing bushings of different sizes, this adjustment method requires manual adjustment of two sets of screws, which is time-consuming. At the same time, there will be deviations when adjusting the two sets of screws, and it is difficult to accurately control the two sets of pressure plates to adjust the same distance, making it impossible to fix the bushing in the center of the lower mold.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] In one embodiment, Figure 1-Figure 7 As shown, a high-precision automobile bushing stamping processing device includes a frame 1, which is designed in a "mouth" shape. A lower mold 204 for placing the bushing is connected to the upper inner side of the frame 1 through a support column, and a stamping assembly for driving the upper mold 402 is connected to the upper end of the frame 1. A plurality of groups of center clamping assemblies for clamping and positioning the bushing are arranged in the lower mold 204, which are used to position and clamp the bushing. A driving assembly for driving the center clamping assembly to operate is arranged on the upper inner side of the frame 1.

[0028] like Figure 2-6As shown, the drive assembly includes a motor 2, a worm 201, a worm wheel ring 202 and a spur gear 203. The surfaces of the worm wheel ring 202 and the spur gear 203 are sprayed with a galvanized layer to prevent rust and extend the service life. The motor 2 is arranged on the inner upper surface of the frame 1 and the output end is connected to the worm 201. The end of the worm 201 away from the motor 2 is rotatably connected to the inner wall of the frame 1. The worm 201 is rotatably connected to multiple sets of brackets 206 through bearings, and the brackets 206 are connected to the frame 1, which increases the rotation of the worm 201. In order to ensure stability, the worm 201 is meshed with a worm gear ring 202. The lower surface of the worm gear ring 202 is rotationally connected to the frame 1 and the upper surface is rotationally connected to the lower mold 204. When the worm wheel 201 rotates under the action of the motor 2, the worm gear ring 202 is driven to start rotating. The inner side of the worm gear ring 202 is provided with gear teeth and the gear teeth are meshed with a spur gear 203. When the worm gear ring 202 starts to rotate, the spur gear 203 is driven to rotate through the gear teeth. The spur gear 203 is rotationally connected to the frame 1 and the lower mold 204.

[0029] like Figure 4 , Figure 5 and Figure 6 As shown, the center clamping assembly includes an inner guide ring 205, a rack 3 and a positioning plate 301. The inner guide ring 205 is arranged on the inner side of the lower mold 204 and is fixedly connected to the frame 1. Multiple groups of racks 3 are slidably connected to the inner guide ring 205. The racks 3 are meshed with the spur gear 203. When the spur gear 203 rotates, the rack 3 is driven to start moving. A positioning plate 301 is arranged at the end of the rack 3. The movement of the rack 3 causes the positioning plate 301 to clamp or release the bushing. A buffer pad 302 is arranged on the surface of the positioning plate 301.

[0030] like Figure 1 and Figure 7 As shown, the stamping assembly includes a cylinder 4 and a mounting plate 401. The cylinder 4 is arranged at the upper end of the frame 1 and is connected to the frame 1 through a support column. The output end of the cylinder 4 is connected to the mounting plate 401, and the mounting plate 401 is connected to the upper mold 402. When the cylinder 4 is started, the mounting plate 401 and the upper mold 402 are pushed downward. The upper mold 402 is detachably connected to the mounting plate 401 through a hexagon socket screw, which is convenient for disassembly and replacement of the upper mold 402.

[0031] The above embodiment discloses a high-precision automobile bushing stamping processing device, wherein the bushing is placed in the lower die 204, the motor 2 is started, so that the worm 201 drives the worm ring 202 to rotate, and finally drives the rack 3 to move and clamp the bushing, and the cylinder 4 is started to complete the stamping work.
