Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1-7As shown, a positioning fixture for flange processing includes a clamping mechanism 1. An adjusting mechanism 2 is located on the back of the clamping mechanism 1. The adjusting mechanism 2 includes a motor 202 and an electric telescopic rod 205. The adjusting mechanism 2 also includes an extension rod 210. The extension rod 210 has insertion ports 214 on both sides of its end. Insert plates 216 are inserted into the insertion ports 214. Insert holes 217 are formed on the surface of the insert plates 216. The two insert plates 216 extend out of the extension rod 210 and are jointly and fixedly connected to a support rod 218. A brush 219 is rotatably connected to the outer wall of the support rod 218. The extension rod 210... A push rod 211 is slidably connected to the middle of the outer wall of extension rod 210. A spring 212 is fixedly connected to the outer wall of push rod 211, and the other end of spring 212 is fixedly connected to the inner wall of extension rod 210. A pressing plate 213 is fixedly connected to the push rod 211 on the side away from spring 212. The ends of pressing plate 213 are beveled on both sides. A ball bearing 215 is movably installed on the inner wall of extension rod 210 between the end of pressing plate 213 and insertion port 214. One side of ball bearing 215 abuts against the beveled end of pressing plate 213, and the other end of ball bearing 215 abuts against the inside of insertion hole 217. Figure 2 As shown, after the extrusion plate 213 moves to the left, it cancels the support for the ball 215, so that when the insert plate 216 separates from the insertion port 214, the ball 215 does not obstruct it. The adjustment mechanism 2 also includes a support frame 201. One inner wall of the support frame 201 is fixedly installed with a motor 202. The other inner wall of the support frame 201 has a guide groove 203. A guide rod 204 is slidably connected inside the guide groove 203. The outer wall of the support frame 201 is also fixedly installed with an electric telescopic rod 205. The extension end of the electric telescopic rod 205 is fixedly connected to the guide rod 204. An end block 206 is fixedly connected to the end of the guide rod 204 away from the guide groove 203. A movable plate 207 is slidably connected through the inner wall of the end block 206. The end of the movable plate 207 away from the end block 206 is fixedly connected to an extension rod 210. A groove 208 is formed on the surface of the movable plate 207. A gasket is fixedly connected to the inner side of the groove 208. A threaded shaft 209 is threadedly connected to the outer wall of the end block 206. The end of the threaded shaft 209 abuts against the inner side of the groove 208. Figure 3 As shown, the loose threaded shaft 209 is rotated to separate its end from the groove 208, so that the moving plate 207 can move along the inner side of the end block 206, thereby adjusting the relative position of the extension rod 210 and the clamping mechanism 1, ensuring that the brush 219 can contact the metal workpiece processing surface. The clamping mechanism 1 includes a limiting circular frame 101, which is fixedly connected to the output shaft of the motor 202 and rotatably connected to the support frame 201. A knob 102 is rotatably connected to one side of the limiting circular frame 101. The knob 102 passes through the inside of the limiting circular frame 101 and is rotatably connected to a bevel gear 103. An annular bevel rack 104 is meshed with the outer side of the bevel gear 103. Both the outer and inner sides of the annular bevel rack 104 are connected to the limiting mechanism. The circular frame 101 is internally rotatably connected, and several limiting blocks 107 are slidably connected to the front of the limiting circular frame 101. A clamping claw 106 is fixedly installed on the side of the limiting block 107 located inside the limiting circular frame 101. Both ends of the clamping claw 106 are connected through to the inner wall of the limiting circular frame 101. The annular bevel rack 104 has a flat thread 105 on the side away from the bevel gear 103. The surface of the flat thread 105 meshes with the surface of the clamping claw 106. Figure 7 As shown, the surface of the clamping claw 106 is provided with textures that engage with the planar thread 105.
[0020] The working principle of this utility model: When the device is in use, the support frame 201 is fixed above the machine tool, the metal workpiece to be processed is placed between each clamping jaw 106, the bevel gear 103 is rotated by the knob 102, the annular bevel rack 104 is rotated inside the limiting circle frame 101, the flat thread 105 pushes the clamping jaw 106 to move, and the limiting block 107 moves linearly on the surface of the limiting circle frame 101, so that the clamping jaw 106 gradually clamps and fixes the workpiece. Secondly, the motor 202 drives the limiting round frame 101 to rotate, which facilitates the processing of the workpiece at different angles. After a single processing is completed, the electric telescopic rod 205 retracts, which drives the support rod 218 and brush 219 at the end of the extension rod 210 to approach the metal workpiece inside the clamping claw 106. The motor 202 drives the limiting round frame 101 to rotate continuously, thereby removing the debris from the surface of the metal workpiece. Furthermore, when disassembling the support rod 218 and the brush 219, push the push rod 211 away from the support rod 218, causing the pressing plate 213 to separate from the balls 215 on both sides. As a result, the balls 215 release their tight contact with the inside of the insertion hole 217, and the insertion plate 216 can be pulled out from the insertion port 214. At this time, the support rod 218 and the brush 219 separate from the extension rod 210.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
