Furthermore, picosecond laser micro-hole machining positioning devices offer advantages such as accurate positioning and high processing efficiency, making them widely applicable in fields requiring high-precision micro-hole machining.
[0003] The clamping plates of existing picosecond laser micro-hole processing positioning devices protrude from the device surface when not in use. These protruding clamping plates pose a potential safety hazard, as operators may accidentally touch them during operation, resulting in accidental injuries such as pinching or scratches. Utility Model Content
[0004] The purpose of this invention is to provide a picosecond laser micro-hole processing positioning device, which improves the safety of device use and solves the problem of poor safety in the existing technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A picosecond laser micro-hole processing positioning device includes a base with two conical teeth rotatably connected inside. The base also has two sliding grooves, with rods rotatably connected inside each groove. The ends of the rods are fixedly connected to the sidewalls of the conical teeth. A crossbar is fixedly connected between the inner walls of the two sides of the sliding grooves. The upper end of the base has two receiving slots. Two movable plates are slidably disposed within the sliding grooves. The rods are threadedly connected to the movable plates, and the crossbars are slidably connected through the movable plates. The upper end of each movable plate has a slot, with a movable rod slidably connected inside the slot. A spring is fixedly connected between the lower end of the movable rod and the bottom of the slot. An electromagnet is fixedly connected to the bottom of the slot. A permanent magnet is fixedly connected inside the lower end of the movable rod. The electromagnet and the permanent magnet cooperate. The movable rod is slidably connected to the upper end of the base. A clamping plate is fixedly connected to the upper end of the movable rod. The clamping plate is slidably connected to the storage slot. A ring plate is rotatably disposed on the outside of the base. A bracket is fixedly connected to the upper end of the ring plate. A groove is provided at the top of the bracket. A movable block is slidably connected inside the groove. A laser head is fixedly connected through the movable block.
[0007] Preferably, a main motor is fixedly connected inside the base, and a gear is rotatably connected inside the base, with the output end of the main motor fixedly connected to the lower end of the gear.
[0008] Preferably, the inner wall of the ring plate is provided with a plurality of tooth blocks, which are distributed in a ring array and mesh with the side wall of the gear.
[0009] Preferably, a motor is fixedly connected inside the base, and a main bevel gear is rotatably connected inside the base. The lower end of the main bevel gear is fixedly connected to the output end of the motor, and the main bevel gear meshes with the bevel gear.
[0010] Preferably, a servo motor is fixedly connected inside the side wall of the bracket, a screw is rotatably connected inside the groove, the end of the screw is fixedly connected to the output end of the servo motor, and the screw is threadedly connected to the movable block.
[0011] Preferably, a guide rod is fixedly connected between the inner walls on both sides of the groove, and the guide rod is slidably connected to the movable block through it.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] 1. The sheet metal workpiece to be processed is placed on the upper end of the base. Then, the electromagnet is energized to generate a repulsive magnetic force with the permanent magnet. The permanent magnet pushes the movable rod to slide upward a suitable distance, so that the movable rod pushes the clamping plate out of the storage groove. The bevel tooth drives the rod to rotate, so that the two movable plates slide laterally inward relative to each other. The movable plates drive the clamping plate to slide laterally through the movable rod. The lower end of the clamping plate slides laterally out from the top of the storage groove and fits against the upper end of the base. The side wall of the clamping plate is in close contact with the side wall of the workpiece. The workpiece is clamped and positioned by the two relatively sliding clamping plates, which facilitates the clamping and positioning of the workpiece for processing.
[0014] 2. When clamping and positioning of the workpiece is not required, the motor drives the main bevel gear to rotate in the opposite direction. Through the cooperation between the main bevel gear and the bevel gear, the bevel gear rotates accordingly. The bevel gear drives the rod to rotate. Through the threaded cooperation between the rod and the movable plate, the two movable plates slide laterally outward. The movable plate drives the clamping plate to slide laterally through the movable rod. The clamping plate slides to the top of the storage slot. Then, the electromagnet is de-energized and the magnetic force repelling the permanent magnet disappears. The spring force pulls the movable rod downward and slides. At the same time, the clamping plate slides into the storage slot for safe storage. The clamping plate does not protrude from the surface of the base when stored, reducing the risk of accidental collision or pinching injury to the operator and improving workplace safety.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5A picosecond laser micro-hole processing positioning device includes a base 001, with two conical teeth 105 rotatably connected inside the base 001. Two sliding grooves 106 are provided inside the base 001, and rods 107 are rotatably connected inside the sliding grooves 106. The ends of the rods 107 are fixedly connected to the sidewalls of the conical teeth 105. A crossbar 108 is fixedly connected between the inner walls of the two sides of the sliding grooves 106. Two storage slots 109 are provided at the upper end of the base 001. Two movable plates 002 are slidably disposed inside the sliding grooves 106. The rods 107 are threadedly connected to the movable plates 002, and the crossbars 108 are threadedly connected to the movable plates 002. The movable plate 002 is slidably connected through the plate. The upper end of the movable plate 002 is provided with a slot 201. A movable rod 202 is slidably connected inside the slot 201. A spring 203 is fixedly connected between the lower end of the movable rod 202 and the bottom of the slot 201. An electromagnet 204 is fixedly connected to the bottom of the slot 201. A permanent magnet 205 is fixedly connected inside the lower end of the movable rod 202. The electromagnet 204 cooperates with the permanent magnet 205. The movable rod 202 is slidably connected through the plate to the upper end of the base 001. A clamping plate 206 is fixedly connected to the upper end of the movable rod 202. The clamping plate 206 is slidably connected to the storage slot 109.A ring plate 003 is rotatably mounted on the outside of the base 001. A bracket 302 is fixedly connected to the upper end of the ring plate 003. A groove 303 is provided at the top of the bracket 302. A movable block 304 is slidably connected inside the groove 303. A laser head 305 is fixedly connected through the movable block 304. The connection end of the laser head 305 is connected to the connection end of an external laser device. Both the movable rod 202 and the slot 201 are rectangular. The operator places the workpiece to be processed on the upper end of the base 001. Then, the electromagnet 204 is energized, generating a repulsive magnetic force with the permanent magnet 205. The permanent magnet 205 pushes the movable rod 202 upward to slide an appropriate distance, so that the movable rod 202 pushes the clamping plate 206 out of the receiving groove 109. At the same time, the spring 203 is stretched. The lower part of the movable rod 202 is still located inside the slot 201. Then, the bevel tooth 105 drives the rod body 107 to rotate. Through the threaded engagement between the rod body 107 and the movable plate 002... This causes the two movable plates 002 to slide laterally relative to each other, while the movable rod 202 slides laterally as well. The movable rod 202 also drives the clamping plate 206 to slide laterally. The lower end of the clamping plate 206 slides laterally out from above the receiving groove 109 and fits against the upper end of the base 001. After the sidewall of the clamping plate 206 makes tight contact with the sidewall of the workpiece, the bevel tooth 105 stops rotating. The workpiece is clamped and positioned by the two relatively sliding clamping plates 206. Then, the movable block 304 drives the laser head 305 to slide laterally. After the laser head 305 moves to the position above the workpiece where micro-hole processing is required, the movable block 304 stops sliding. The laser head 305 then emits picosecond-level laser pulses to perform micro-hole processing on the workpiece. When processing is needed on other parts of the workpiece, the ring plate 003 drives the support 302 to rotate, adjusting the support 302 to an appropriate angle. Then, the movable block 304 drives the laser head 305 to slide laterally, thus facilitating picosecond laser micro-hole processing on different positions of the workpiece.
[0023] A main motor 101 is fixedly connected inside the base 001, and a gear 102 is rotatably connected inside the base 001. The output end of the main motor 101 is fixedly connected to the lower end of the gear 102, and the gear 102 is driven to rotate by the main motor 101.
[0024] The inner wall of the ring plate 003 is provided with multiple tooth blocks 301, which are arranged in a ring array. The tooth blocks 301 mesh with the side wall of the gear 102. When the gear 102 rotates, it pushes the multiple tooth blocks 301 in sequence, thereby causing the ring plate 003 to rotate.
[0025] A motor 103 is fixedly connected inside the base 001, and a main bevel gear 104 is rotatably connected inside the base 001. The lower end of the main bevel gear 104 is fixedly connected to the output end of the motor 103. The main bevel gear 104 meshes with the bevel gear 105. The motor 103 drives the main bevel gear 104 to rotate, and the bevel gear 105 rotates accordingly through the cooperation between the main bevel gear 104 and the bevel gear 105.
[0026] A servo motor 307 is fixedly connected inside the side wall of the bracket 302, and a screw 306 is rotatably connected inside the groove 303. The end of the screw 306 is fixedly connected to the output end of the servo motor 307. The screw 306 is threadedly connected to the movable block 304. The servo motor 307 drives the screw 306 to rotate, and the screw 306 slides through the threaded engagement between the screw 306 and the movable block 304.
[0027] A guide rod 308 is fixedly connected between the inner walls on both sides of the groove 303. The guide rod 308 is slidably connected to the movable block 304. During the sliding process of the movable block 304, it is guided and limited by the guide rod 308.
[0028] In this invention, the operator places the workpiece to be processed on the upper part of the base 001. Then, the electromagnet 204 is energized, generating a repulsive magnetic force against the permanent magnet 205. The permanent magnet 205 pushes the movable rod 202 upwards a suitable distance, causing the movable rod 202 to push the clamping plate 206 out of the receiving groove 109. Simultaneously, the spring 203 is stretched, and the motor 103 drives the main bevel gear 104 to rotate in the forward direction. Through the cooperation between the main bevel gear 104 and the bevel gear 105, the bevel gear 105 rotates accordingly. The tooth 105 drives the rod 107 to rotate. Through the threaded engagement between the rod 107 and the movable plate 002, the two movable plates 002 slide laterally inward. The movable plate 002 drives the clamping plate 206 to slide laterally through the movable rod 202. The lower end of the clamping plate 206 slides laterally out from above the storage groove 109 and fits against the upper end of the base 001. After the side wall of the clamping plate 206 comes into close contact with the side wall of the workpiece, the bevel tooth 105 stops rotating. The workpiece is clamped and positioned by the two relatively sliding clamping plates 206.
[0029] After the workpiece is clamped and positioned, the servo motor 307 drives the screw 306 to rotate. Through the threaded engagement between the screw 306 and the movable block 304, the movable block 304 slides. The movable block 304 drives the laser head 305 to slide laterally. After the laser head 305 moves to the position above the workpiece where micro-hole processing is required, the movable block 304 stops sliding. Then, the laser head 305 emits picosecond-level laser pulses to perform micro-hole processing on the workpiece. When processing is required on other parts of the workpiece, the main motor 101 drives the gear 102 to rotate. The gear 102 sequentially pushes multiple toothed blocks 301, causing the ring plate 003 to rotate. The ring plate 003 drives the support 302 to rotate. After the support 302 is adjusted to an appropriate angle, the ring plate 003 stops rotating. Then, the movable block 304 drives the laser head 305 to slide laterally, thus facilitating picosecond laser micro-hole processing on different positions of the workpiece.
[0030] When clamping and positioning of the workpiece is not required, the motor 103 drives the main bevel gear 104 to rotate in the opposite direction. Then, through the cooperation between the main bevel gear 104 and the bevel gear 105, the bevel gear 105 rotates accordingly. The bevel gear 105 drives the rod body 107 to rotate. Through the threaded cooperation between the rod body 107 and the movable plate 002, the two movable plates 002 slide laterally outward relative to each other. The movable plate 002 drives the clamping plate 206 to slide laterally through the movable rod 202. The clamping plate 206 slides to the top of the storage slot 109. Then, the electromagnet 204 is de-energized, and the magnetic force repelling the permanent magnet 205 disappears. The spring force of the spring 203 pulls the movable rod 202 downward to slide. At the same time, the clamping plate 206 slides into the storage slot 109 for hidden storage.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
