[0026] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a clamping device for irregular workpieces, comprising a work platform 1, an installation platform 12 fixedly connected to the top of the work platform 1, a plurality of workpiece support rods 17 equidistantly installed on the top of the installation platform 12, a workpiece 13 to be processed being placed on the top of the workpiece support rods 17, and the workpiece 13 to be processed being supported by the installation of the workpiece support rods 17, a balance support rod 14 being installed on the left and right sides of the front side of the installation platform 12, an adjustment rod 16 being provided on the right side of each of the two balance support rods 14, a pressure rod 15 being rotatably connected to the top of the adjustment rod 16, the left side of the pressure rod 15 being fixedly connected to the top of the balance support rod 14, a cleaning mechanism 2 being installed on the rear side of the work platform 1, the cleaning mechanism 2 being used for cleaning debris, a slot plate 6 being fixedly connected to the right side of the work platform 1, a notice board 5 being installed in the middle of the slot plate 6, the notice board 5 being installed to facilitate reminders to workers; Specifically, before processing the workpiece, to ensure that the workpiece 13 to be processed can be stably clamped, the workpiece 13 to be processed is first placed on top of multiple workpiece support rods 17. Then, by installing the adjusting rod 16, it is ensured that its bottom threaded part can be installed and tightened to achieve the effect of fixing the support rod. Subsequently, by installing two balance support rods 14, the function of these two balance support rods 14 is to ensure that the pressure rod 15 can be evenly stressed when pressure is applied, so that the pressure rod 15 can move downward smoothly. When the pressure rod 15 moves downward, the workpiece 13 to be processed is clamped and fixed in the appropriate position, thereby improving the clamping effect. Through the above process, the workpiece 13 to be processed can be effectively clamped and fixed, thereby avoiding unnecessary movement during processing and ensuring processing accuracy and efficiency.

[0027] Reference Figure 1 , Figure 3 and Figure 5 The cleaning mechanism 2 includes a fixed square plate 201, which is fixedly connected to the top rear side of the working platform 1. A sliding groove 209 is formed in the middle of the fixed square plate 201. A mounting box 208 is installed on the rear side of the fixed square plate 201, and a motor 202 is installed in the middle of the rear side of the mounting box 208. The motor 202 provides power to subsequent processes. A drive gear 204 is fixedly connected to the output end of the motor 202. Driven gears 203 are rotatably connected to the upper and lower ends of the mounting box 208. Adjacent sides of the two driven gears 203 mesh with the upper and lower ends of the drive gear 204, respectively. Half gears 205 are fixedly connected to the front sides of the two driven gears 203. The sliding groove 209 is slidably connected... A rack 206 is attached, with its upper and lower ends respectively connected to the adjacent sides of two half gears 205. The rack 206 can reciprocate through the installation of the half gears 205. A fan 207 is installed in the middle of the front side of the rack 206. Support rods 4 are fixedly connected to the left and right rear sides of the mounting box 208. A support plate 3 is fixedly connected to the top of the support rods 4. The motor 202 can be stably installed through the installation of the support rods 4. A collection box 8 is fixedly connected to the bottom front side of the working platform 1. A rotating rod 9 is rotatably connected to the top front side of the collection box 8. The installation of the collection box 8 facilitates the collection of debris. Multiple heat dissipation slots 20 are equidistantly opened on the rear side of the mounting box 208 to prevent excessive internal heat. Specifically, the motor 202 is started, driving the drive gear 204 to rotate. The two driven gears 203 that mesh with the upper and lower ends of the drive gear 204 also rotate synchronously. At the same time, the half gear 205 on the front side of the driven gear 203 also starts to operate. Since the teeth of the half gear 205 are partial, during the rotation, it periodically meshes and disengages with the rack 206 in the sliding groove 209, thereby driving the rack 206 to perform reciprocating linear motion. The fan 207 installed in the middle of the front side of the rack 206 moves back and forth accordingly. The wind force generated by the motor 202 blows away the debris on the work platform 1. Through the above process, it is ensured that the debris can be cleaned in time to avoid adverse effects on subsequent processes.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The collection box 8 is fixedly connected to the rear side of the cover plate 7, and the top of the cover plate 7 is fixedly connected to the handle 10. The handle 10 is fitted with a protective cover 11 on the outside. The working platform 1 is fixedly connected to the middle left side of the sliding box 18, and multiple hooks 19 are equidistantly slidably connected inside the sliding box 18. Specifically, the installation of handle 10 facilitates the opening and closing of cover 7, and the installation of multiple hooks 19 facilitates the storage and use of parts.

[0029] Working principle: When it is necessary to clamp the workpiece 13 to be processed, the workpiece 13 to be processed is first placed on the top of multiple workpiece support rods 17. Then, by installing the adjusting rod 16 and the bottom screw, it is tightened. Then, by installing the two balance support rods 14, the two balance support rods 14 can make the pressure rod 15 evenly stressed, so that the pressure rod 15 moves downward, thereby clamping and fixing the workpiece 13 to be processed, thus improving the clamping effect. Through the above process, the workpiece 13 to be processed can be clamped and fixed, avoiding unnecessary movement. The motor 202 is turned on, which in turn drives the drive gear 204 to rotate. The two driven gears 203 that mesh with the upper and lower ends of the drive gear 204 rotate synchronously. The half gear 205 on the front side of the driven gear 203 also rotates together. Since the half gear 205 only has some teeth, it periodically meshes with and disengages from the rack 206 in the sliding groove 209 during rotation, causing the rack 206 to make reciprocating linear motion. The fan 207 installed in the middle of the front side of the rack 206 moves back and forth accordingly. The wind force generated by the operation blows away the debris on the work platform 1. Through the above process, the debris can be cleaned up in time to avoid adverse effects on subsequent processes.
