Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Referring to Figures 1-7 , a fixing device for milling machine processing, including a base 1, a fixing plate 2 is fixedly installed on the bottom wall of the base 1, a plurality of fixing holes are opened on the upper end surface of the fixing plate 2, a double-headed screw 3 is rotatably installed on the upper end surface of the base 1 through a moving groove, a first motor 4 connected to the double-headed screw 3 is fixedly installed on the outer wall of the base 1, two moving plates 6 are threadedly installed on the outer wall of the double-headed screw 3 through a limiting mechanism, the limiting mechanism includes a limit rod 5 fixedly installed inside the moving groove, the limit rod 5 slidably penetrates through the two moving plates 6, and the limit rod 5 can play a limiting role on the two moving plates 6, so that the two moving plates 6 can only axially move along the outer wall of the double-headed screw 3. Two transmission sleeves 7 and two connecting shafts 8 are rotatably penetrated and installed on the inner walls of the two moving plates 6, belt pulleys 9 are fixedly installed on the outer walls of the two transmission sleeves 7 and the two connecting shafts 8, and the two belt pulleys 9 on the same side are connected and driven by a belt. Clamping frames 10 are fixedly installed at the ends of the two connecting shafts 8.

[0027] Connecting sleeves 12 are fixedly installed on the inner walls on both sides of the two clamping frames 10 through a telescopic mechanism. The telescopic mechanism includes a cylinder 11 fixedly installed on the inner wall of the clamping frame 10, and the telescopic end of the cylinder 11 is fixedly connected to the outer wall of the connecting sleeve 12. A clamping plate 17 is fixedly connected inside each connecting sleeve 12 through a connecting mechanism. The connecting mechanism includes a connecting block 13 slidably installed inside the connecting sleeve 12, the end of the connecting block 13 is fixedly connected to the outer wall of the clamping plate 17, a jack for cooperating with the fixing pin 14 is opened on the outer wall of the connecting block 13, a fixing pin 14 is slidably penetrated and installed on the outer wall of each connecting sleeve 12, and a dialing block 15 is fixedly installed on the outer wall of each fixing pin 14.

[0028] The inner wall of each shifting block 15 is connected to the outer wall of the corresponding connecting sleeve 12 through a fixing mechanism. The fixing mechanism includes a fixing spring 16 installed on the outer wall of the fixing pin 14. The two ends of the fixing spring 16 are elastically connected to the outer wall of the connecting sleeve 12 and the inner wall of the shifting block 15 respectively. An anti-slip pad 18 is fixedly installed on the inner wall of each clamping plate 17. Each anti-slip pad 18 is made of rubber material. Rubber material has good elasticity and softness, which enables it to form a closer contact between the surface and the object, thereby increasing the friction force and improving the friction coefficient. The upper end surface of the base 1 is rotatably installed with a transmission shaft 20 through a support mechanism. The support mechanism includes two support plates 19 fixedly installed on the upper end surface of the base 1. The transmission shaft 20 is rotatably installed between the two support plates 19.

Before processing the workpiece, the first motor 4 can drive the double-headed screw rod 3 to rotate. When the double-headed screw rod 3 rotates, it can drive the two moving plates 6 to move through the cooperation with the limiting rod 5. At this time, the two moving plates 6 can respectively drive the transmission sleeves 7 on the same side to slide on the outer wall of the transmission shaft 20, and also drive the clamping frames 10 on both sides to move, thereby adjusting the distance between the two clamping frames 10. Then, the workpiece is placed between the two clamping plates 17 on both sides. Subsequently, the two cylinders 11 on both sides can extend simultaneously, so that the two clamping plates 17 on the same side can approach each other and clamp and fix the workpiece through the anti-slip pads 18.

[0030] When it is necessary to clamp and fix workpieces with different shapes, the shifting block 15 can be dialed to drive the fixing pin 14 to move and move out of the jack, thereby releasing the fixation of the connecting block 13 inside the connecting sleeve 12. Subsequently, the connecting block 13 can be pulled out of the connecting sleeve 12, so as to realize the disassembly and installation of different types of clamping plates 17 to clamp and fix workpieces with different shapes. During the processing of the workpiece, the second motor 21 can drive the transmission shaft 20 to rotate. When the transmission shaft 20 rotates, it can drive the two transmission sleeves 7 to rotate. The two transmission sleeves 7 respectively drive the two connecting shafts 8 to rotate through the two belt wheels 9 connected by belts, so that the two connecting shafts 8 can respectively drive the clamping frames 10 on the same side to rotate, thereby driving the clamped and fixed workpiece to rotate, so as to process different parts of the workpiece.
