[0028] Example 1

[0029] A preferred embodiment of an adjustable die-casting product processing positioning fixture provided by the present invention is as follows: Figures 1 to 6 As shown: an adjustable processing positioning fixture for die-casting products, including a base plate 1;

[0030] An L-shaped plate 3 disposed on the top of the base plate 1;

[0031] A limiting column 4 is fixedly arranged on the top of the L-shaped plate 3;

[0032] and an adjusting assembly 2 disposed on the bottom plate 1, the adjusting assembly 2 comprising an adjusting portion 21 and a pressing portion 23, the adjusting portion 21 being located inside the bottom plate 1, a rotating portion 22 being disposed outside the adjusting portion 21, the pressing portion 23 being located at the top of the bottom plate 1, and a mounting portion 24 being disposed at the bottom of the pressing portion 23;

[0033] The adjusting part 21 includes a guide groove 211 and a rotating shaft 212. The guide groove 211 is located at the top of the bottom plate 1. The top and bottom ends of the rotating shaft 212 are rotatably connected to the inner wall of the bottom plate 1 through bearings. A gear 213 is fixedly installed on the outer wall of the rotating shaft 212. A rack 216 is meshed with the gear 213. A connecting plate 217 is fixedly installed on the outer wall of the rack 216. A connecting rod slidably arranged in the guide groove 211 is fixedly installed on the top of the connecting plate 217, and the top of the connecting rod is fixedly connected to the bottom of the L-shaped plate 3. A T-slot 214 is provided on the top of the outer wall of the rack 216, and a T-block 215 is slidably arranged inside the T-slot 214. The top of the T-block 215 is fixedly connected to the bottom of the bottom plate 1. The connecting plate 217 and the connecting rod are used to adjust the position of the L-shaped plate 3, thereby adjusting the position of the limit column 4. The guide groove 211 is provided to specify the direction and distance in which the L-shaped plate 3 can move. 213 and the rack 216 make it possible to move the connecting disk 217 and the connecting rod by rotating the rotating shaft 212. The T-slot 214 and the T-block 215 are provided to limit the rack 216 so that the rack 216 can only move along the T-slot 214. The rotating part 22 includes a worm wheel 223. The inner wall of the worm wheel 223 is fixedly connected to the outer wall of the rotating shaft 212. The worm wheel 223 is meshed with a worm 221. The end of the worm 221 facing the front passes through the inner wall of the bottom plate 1 through a bearing. The end of the worm 221 facing the front is fixedly installed with a turning handle 222. The worm 221 is driven to rotate by turning the turning handle 222, and then the worm wheel 223 is driven to rotate, so that the worm wheel 223 rotates and drives the rotating shaft 212 to rotate. By utilizing the self-locking properties of the worm wheel 223 and the worm 221, there is no need to worry about the die-casting product squeezing the limiting column 4 and then pushing the L-shaped plate 3 so that the connecting rod and the connecting disk 217 push the rack 216 in the opposite direction to move.

[0034] Place the die-cast product on the base plate 1, turn the handle 222 to drive the worm 221 to rotate, and then drive the worm wheel 223 to rotate. The rotation of the worm wheel 223 drives the shaft 212 to rotate, and then drives the gear 213 to rotate. The rotation of the gear 213 drives the rack 216 to move. As the rack 216 moves, it drives the connecting plate 217 and the connecting rod to move, and then drives the L-shaped plate 3 to move. The movement of the L-shaped plate 3 drives the limit column 4 to move, and the corners of the die-cast product are limited to prevent the die-cast product from moving.

[0035] In this embodiment, four L-shaped plates 3 are provided and symmetrically distributed at the four corners of the top of the base plate 1, so that the corresponding limiting columns 4 limit the four corners of the die-cast product. The side of the limiting column 4 facing the center of the base plate 1 is located on the same vertical plane as the side of the L-shaped plate 3, ensuring that when the L-shaped plate 3 contacts the die-cast product, the limiting column 4 can also contact the die-cast product. Two gears 213 are provided and vertically distributed on the rotating shaft 212. Four racks 216 are provided, and every two racks 216 form a group. Each group of racks 216 is meshed with the same gear 213, so that when the rotating shaft 212 rotates, the positions of the four L-shaped plates 3 can be adjusted, making the adjustment more convenient.

[0036] Example 2

[0037] On the basis of Example 1, a preferred embodiment of an adjustable die-casting product processing positioning fixture provided by the present invention is as follows Figures 1 to 6 As shown: the pressing part 23 includes a moving block 232 and an electric telescopic rod 235. A connecting plate 234 is fixedly installed on the top of the electric telescopic rod 235. A screw rod 233 is threadedly connected to the inner wall of the connecting plate 234. The screw rod 233 passes through the inner wall of the moving block 232 through a bearing. A limiting rod 236 is fixedly installed on the outer wall of the connecting plate 234. The limiting rod 236 movably passes through the outer wall of the moving block 232. A pressing rod 231 is fixedly installed on the bottom of the moving block 232. The limiting rod 236 is set to limit the moving block 232, so that when the screw rod 233 is rotated, the moving block 232 cannot rotate and can only move with the movement of the screw rod 233. The electric telescopic rod 235 and the connecting plate 234 are used to adjust the height of the moving block 232, and then adjust the height of the pressing rod 231. A soft pad 5 is installed at the bottom of the pressing rod 231 to prevent the pressing rod from When 231 is pressed on the die-cast product, the die-cast product is damaged. Two electric telescopic rods 235 are provided, and are respectively located on the left and right sides of the top of the bottom plate 1 to press and limit the two ends of the die-cast product. The mounting portion 24 includes an insertion rod 244 and a mounting groove 245. The mounting groove 245 is located at the top of the bottom plate 1. The inner wall of the mounting groove 245 is clamped with a mounting block 241. The top of the mounting block 241 is fixedly connected to the bottom of the electric telescopic rod 235. The insertion rod 244 movably penetrates the inner wall of the mounting groove 245 and the outer wall of the mounting block 241. A baffle 243 is fixedly installed at one end of the insertion rod 244 away from the mounting block 241. A spring 242 is movably sleeved on the outer wall of the insertion rod 244. The end of the spring 242 away from the bottom plate 1 is fixedly connected to the outer wall of the baffle 243, and the other end of the spring 242 is fixedly connected to the side outer wall of the bottom plate 1.

[0038] After adjusting the position of the limit column 4, the screw rod 233 is rotated so that the screw rod 233 drives the moving block 232 to move horizontally, and then drives the pressure rod 231 to move, so that the pressure rod 231 moves to the edge position of the die-casting product, and the electric telescopic rod 235 is turned on to drive the connecting plate 234 to move downward, thereby driving the screw rod 233 to move downward. The downward movement of the screw rod 233 drives the moving block 232 to move downward, and then drives the pressure rod 231 to move downward to press the die-casting product downward to limit the position. When the positioning fixture needs to be stored, the baffle plate 243 is pulled outward to drive the insertion rod 244 to move outward, so that the insertion rod 244 is separated from the mounting block 241, and the electric telescopic rod 235 can be pulled upward to drive the mounting block 241 to separate from the mounting groove 245, and the pressing part 23 is disassembled, so that when the fixture is cleaned before storage, the electric telescopic rod 235 is soaked in water and damaged.
