Description

Technical Field

[0001] This utility model relates to a positioning fixture, specifically a flocking positioning fixture adapted to irregularly shaped workpieces, belonging to the technical field of flocking devices. Background Technology

[0002] In modern industrial production, flocking technology is a commonly used surface treatment technique widely applied in various fields, especially in the production of automotive parts, electronic components, toys, and decorations. Flocking is a technique that electrostatically adsorbs short fibers (usually nylon or polyester fibers) onto the surface of an object, creating a soft and delicate velvety effect that enhances the appearance and feel of the product.

[0003] A device for uniform flocking of irregular curved surfaces, disclosed in Chinese Patent Application Publication CN222197669U, achieves efficient clamping of irregular curved workpieces by setting micro-cylinder driven clamping plates at the four corners of the placement plate and supplementing them with flexible limiting strips. The rapid response and precise control of the micro-cylinders ensure uniform and adjustable clamping force, while the flexible limiting strips effectively prevent damage to the workpiece during clamping. The combined design of the slide, slider, and buffer springs one and two provides additional stability and buffer protection for the clamping system. This design not only further reduces the impact on the workpiece during clamping but also significantly improves the stability and reliability of clamping, ensuring the stability of the workpiece position during flocking. The placement plate is connected to a variable frequency motor via a rotating shaft, allowing the workpiece to rotate during flocking. This design is particularly suitable for flocking irregular curved workpieces because the rotation of the workpiece ensures the uniform distribution of flocking material on the workpiece surface, improving the uniformity and quality of flocking.

[0004] In the above patented solutions, by setting up clamping plates driven by micro cylinders at the four corners of the placement plate and supplementing them with flexible limiting strips, it is possible to achieve efficient clamping of irregular curved workpieces. However, this method uses four independent micro cylinders, which require controlling the synchronization and force of each cylinder's movement separately, making control more difficult and increasing manufacturing costs.

[0005] Therefore, a flocking positioning fixture adapted to irregularly shaped workpieces is proposed here. Utility Model Content

[0006] This invention proposes a flocking positioning fixture adapted to irregularly shaped workpieces, which can more conveniently clamp and position workpieces with different regular curved surfaces, reducing manufacturing costs and control difficulties.

[0007] This utility model is achieved through the following technical solution: a flocking positioning fixture adapted to irregularly shaped workpieces, including a fixing plate, a clamping mechanism on the fixing plate, and a positioning component on the clamping mechanism.

[0008] The clamping mechanism includes a turntable rotatably connected to the upper surface of a fixed plate and a gear rotatably connected to the upper surface of the fixed plate. A toothed ring is fixed on the outer surface of the turntable, and the gear meshes with the toothed ring.

[0009] The turntable has multiple movable slots, and a movable rod slides in contact with the inner wall of the movable slot. A fixing block is fixed to the top of the movable rod, and the bottom surface of the fixing block slides in contact with the upper surface of the turntable. A positioning plate is fixed to one side of the fixing block.

[0010] Furthermore, a rotary motor is fixed to the bottom surface of the fixing plate, and the output shaft end of the rotary motor passes through the fixing plate and is fixed to the bottom surface of the gear.

[0011] Furthermore, the middle portions of the fixing plate and the turntable are respectively provided with a first through groove and a second through groove, and the positioning plate is located in the second through groove.

[0012] Furthermore, a limiting plate is provided on the upper surface of the turntable, and a sliding groove is provided on the limiting plate. A slider is fixed on one side of the fixing block, and the outer surface of the slider is slidably connected to the inner wall of the sliding groove.

[0013] Furthermore, a support plate is fixed to the outer surface of the limiting plate, and the bottom surface of the support plate is fixed to the upper surface of the fixing plate.

[0014] Furthermore, the positioning assembly includes multiple sliding rods slidably connected to the inner wall of the hole in the positioning plate. A limit block and a rubber block are respectively fixed at both ends of the sliding rod. A spring is sleeved on the outer surface of the positioning plate and the limit block of the sliding rod. The two ends of the spring are respectively fixed to the side of the positioning plate that is close to the limit block.

[0015] This utility model provides a flocking positioning fixture adapted to irregularly shaped workpieces, which has the following beneficial effects:

[0016] 1. This flocking positioning fixture, adapted to irregularly shaped workpieces, drives a gear to rotate by starting a rotary motor. Due to the meshing of the gear and the gear ring, the rotation of the gear drives the turntable to rotate. The rotation of the turntable drives the moving rod to move along the moving groove. The moving rod drives the fixed block to move. The fixed block can drive the positioning assembly through the positioning plate to clamp and fix workpieces with different regular curved surfaces, thereby reducing manufacturing costs and control difficulty.

[0017] 2. This flocking positioning fixture, which is adapted to irregularly shaped workpieces, allows the rubber blocks to contact the workpiece first when the positioning plate clamps workpieces with different regular curved surfaces. The protruding part of the workpiece will push the rubber blocks to move the sliding rod. The sliding rod can drive the limiting block to stretch the spring, generating tension. This tension can be used to clamp and fix the workpiece with the rubber blocks. As the positioning plate moves, the remaining rubber blocks will clamp and fix the remaining part of the workpiece, thus increasing the clamping contact area with irregular workpieces.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0029] Please see Figures 1-5 The present invention proposes the following implementation scheme: a flocking positioning fixture adapted to irregularly shaped workpieces, including a fixing plate 1, a clamping mechanism 2 on the fixing plate 1, and a positioning component 3 on the clamping mechanism 2.

[0030] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The clamping mechanism 2 includes a turntable 201 rotatably connected to the upper surface of the fixed plate 1 and a gear 203 rotatably connected to the upper surface of the fixed plate 1. A toothed ring 202 is fixed on the outer surface of the turntable 201, and the gear 203 meshes with the toothed ring 202.

[0031] The turntable 201 has multiple moving slots 204. The inner wall of the moving slot 204 is in sliding contact with a moving rod 205. The top of the moving rod 205 is fixed with a fixing block 206. The bottom surface of the fixing block 206 is in sliding contact with the upper surface of the turntable 201. A positioning plate 207 is fixed on one side of the fixing block 206.

[0032] A rotary motor 208 is fixed to the bottom surface of the fixed plate 1, and the output shaft end of the rotary motor 208 passes through the fixed plate 1 and is fixed to the bottom surface of the gear 203.

[0033] The middle portions of the fixed plate 1 and the turntable 201 are respectively provided with a first through groove 101 and a second through groove 2011, and the positioning plate 207 is located in the second through groove 2011.

[0034] By starting the rotary motor 208, the gear 203 is driven to rotate. Due to the meshing of the gear 203 and the gear ring 202, the rotation of the gear 203 can drive the turntable 201 to rotate. The rotation of the turntable 201 can drive the moving rod 205 to move along the moving groove 204. The moving rod 205 can drive the fixed block 206 to move. The fixed block 206 can drive the positioning assembly 3 to position workpieces with different regular curved surfaces through the positioning plate 207, thereby reducing manufacturing costs and control difficulty.

[0035] Please refer to this carefully. Figure 5 The positioning component 3 includes multiple slide rods 301 that are slidably connected to the inner wall of the hole on the positioning plate 207. The two ends of the slide rods 301 are respectively fixed with a limit block 303 and a rubber block 304. A spring 302 is sleeved on the outer surface of the slide rods 301 on the positioning plate 207 and the limit block 303. The two ends of the spring 302 are respectively fixed to the side of the positioning plate 207 that is close to the limit block 303.

[0036] When the positioning component 3 clamps workpieces with different regular curved surfaces, the rubber block 304 will first contact the workpiece. The protruding part of the workpiece will push the rubber block 304 to drive the slide rod 301 to move. The slide rod 301 can drive the limit block 303 to stretch the spring 302, so that it generates tension. The tension can be used to clamp and fix the rubber block 304 to the workpiece. As the positioning plate 207 moves, the remaining rubber blocks 304 will clamp and fix the remaining part of the workpiece, which improves the clamping contact surface with irregular workpieces.

[0037] Please refer to this carefully. Figure 1 and Figure 4 The upper surface of the turntable 201 is provided with a limiting plate 4, and a sliding groove 401 is provided on the limiting plate 4. A slider 2061 is fixed on one side of the fixing block 206, and the outer surface of the slider 2061 is slidably connected to the inner wall of the sliding groove 401, which can guide and limit the movement of the fixing block 206, thereby improving the stability of the positioning plate 207.

[0038] A support plate 402 is fixed to the outer surface of the limiting plate 4, and the bottom surface of the support plate 402 is fixed to the upper surface of the fixing plate 1.

[0039] In use, the workpiece is placed in the first through groove 101 and the second through groove 2011 on the turntable 201 and the first through groove 101. Then, the rotary motor 208 is started to drive the gear 203 to rotate. Due to the meshing of the gear 203 and the gear ring 202, the rotation of the gear 203 can drive the turntable 201 to rotate. The rotation of the turntable 201 can drive the moving rod 205 to move along the moving groove 204. The moving rod 205 can drive the fixed block 206 to move. The fixed block 206 can drive the positioning plate 207 to move. The positioning plate 207 will... The rubber block 304 is brought into contact with the workpiece. The protruding part of the workpiece will push the rubber block 304 to move the slide rod 301. The slide rod 301 can drive the limiting block 303 to stretch the spring 302, so that it generates tension. The tension can be used to clamp and fix the rubber block 304 to the workpiece. As the positioning plate 207 moves, the remaining rubber blocks 304 will clamp and fix the remaining part of the workpiece, which increases the clamping contact surface with irregular workpieces, thereby positioning workpieces with different regular curved surfaces, thereby reducing manufacturing costs and control difficulty.
