[0003] A clamp is needed during the mechanical processing process, but the existing mechanical processing clamps are mostly used to clamp rectangular parts during use, and cannot clamp round pipes well. At the same time, when some clamps are used to clamp round pipes, the outer surface of the pipe will be occupied, which will affect the normal processing of the pipe. Therefore, we propose a clamp for mechanical processing. Summary of the invention

[0012] Compared with the prior art, the present invention provides a mechanical processing fixture having the following beneficial effects: 1.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] See also Figure 1-7The present invention provides a technical solution: a mechanical processing fixture, including a base plate 1, a support frame 2 is fixedly connected to the left side of the top of the base plate 1, a support frame 2 is arranged on the right side of the top of the base plate 1, a connecting device 4 is arranged at one end of the support frame 2 and the support frame 2 3 close to each other, the connecting device 4 includes a placing mechanism 41, a clamping mechanism 42 is arranged on the outer surface of the placing mechanism 41, a supporting mechanism 43, a reinforcing mechanism 44 and a limiting plate 45 are arranged inside the clamping mechanism 42, the placing mechanism 41 includes a cross bar 411, the cross bar 411 is fixedly connected to the support frame 2, and two groups of openings 3 412 and openings 4 413 are opened inside the cross bar 411.

[0021] The clamping mechanism 42 includes two clamping plates 421, and the two clamping plates 421 are respectively fixedly connected to the outer surface of the cross bar 411, and an opening 1 422 is opened at the central axis of the two clamping plates 421, and an opening 2 423 is set at both ends of the two openings 1 422, and a rotating member 424 is set inside the four openings 2 423, and the four rotating members 424 are rotatably connected to the inner walls of the four openings 2 423 through bearings. There are two groups of clamping mechanisms 42, and the two groups of clamping mechanisms 42 are horizontally arranged on the outer surface of the cross bar 411. By squeezing the clamping plates 421 when the circular pipe is inserted into the outer surface of the cross bar 211, the clamping plates 421 can drive the rotating member 424 to support and fix the inner wall of the circular pipe under its own elastic force, so that the circular pipe can be better inserted through the rotating member 421, and the circular pipe can also be fixed to prevent rotation to avoid affecting the normal processing of the circular pipe.

[0022] The supporting mechanism 43 includes two ferrules 431 and protective pads 434. The two ferrules 431 are fixedly connected to the two protective pads 434 respectively. The ends of the two protective pads 434 close to each other are provided with partitions 435. The two partitions 435 respectively penetrate the two ferrules 431 and are fixedly connected to the inner walls of the two ferrules 431. The ends of the two ferrules 431 close to each other are provided with insertion rods 433. The two ferrules 431 are movably plugged with the insertion rods 433. The outer surface of the insertion rods 433 is sleeved with springs 432. When the circular tube squeezes the clamping plate 421, the ferrule 431 can be squeezed through the partition 435, so that the ferrule 431 can be supported by the insertion rods 433 and the springs 432, so that the protective pads 434 can be well extended from the inside of the opening 422 to contact the inner wall of the circular tube, and are squeezed and fixed by extrusion and friction.

[0023] There are two limit plates 45, and the two limit plates 45 pass through the two openings 413 respectively. Both ends of the two limit plates 45 are in contact with the four clamping plates 421 respectively. When the clamping plates 421 are squeezed, the limit plates 45 can be squeezed, so that the limit plates 45 can be deformed under force to support and limit the clamping plates 421. When the clamping plates 421 are squeezed, the circular pipe fittings can be effectively supported and fixed by the limit plates 45.

[0024] There are two groups of reinforcing mechanisms 44, and the two groups of reinforcing mechanisms 44 are respectively arranged inside the two openings 413. The reinforcing mechanisms 44 include sliding rods 441, and the two sliding rods 441 respectively penetrate the two limit plates 45 and are fixedly connected to the two limit plates 45. The right ends of the two sliding rods 441 are sleeved with elastic pads 445. The inner walls of the two openings 413 are fixedly connected with the second clamping sleeve 442 and the arc plate 444. The two sliding rods 441 respectively penetrate the two arc plates 444 and the second clamping sleeve 442. A spring 443 is provided inside each of the second clamping sleeves 442. The two springs 443 are fixedly connected to the two sliding rods 441 respectively. When the limit plate 45 is squeezed and deformed, the sliding rod 441 and the elastic pad 445 can be driven to squeeze the inner wall of the opening four 413, which can effectively prevent the limit plate 45 from deforming too much and affecting the supporting effect on the clamping plate 421. At the same time, by setting the spring 443, the limit plate 45 can be reset, which is convenient for the subsequent support and fixation of the circular pipe fitting.

[0025] When in use, the circular tube is inserted into the outer surface of the cross bar 211. During the insertion process of the circular tube, the inner wall of the circular tube squeezes the clamping plate 421, so that the clamping plate 421 can drive the rotating member 424 to squeeze and contact the inner wall of the circular tube under its own elastic force, so that the circular tube can be better inserted through the rotating member 421. At the same time, the rotation of the circular tube can also be restricted to avoid affecting the processing of the circular tube. During the process of the circular tube squeezing the clamping plate 421, the clamping plate 421 can squeeze the sleeve 431 through the partition 435, so that the sleeve 431 can be close to each other through the insertion rod 433 to squeeze the spring 432, and the elastic force of the spring 432 can make the protective pad 434 extend out of the opening 422 through the sleeve 431, so that the protective pad 434 can better contact with the inner wall of the circular tube to squeeze it, and the circular tube can be effectively fixed through the protective pad 434, and then through the partition 435, The length of the protective pad 434 extending from the opening 422 is limited, which not only ensures the fixing effect of the circular pipe fitting, but also prevents the protective pad 434 from extending out of the opening 422. When the clamping plate 421 is squeezed, the limiting plate 45 can be squeezed to make the limiting plate 45 deform under force, and the clamping plate 421 is supported and limited by the limiting plate 45, so that when the clamping plate 421 is squeezed, the circular pipe fitting can be supported and fixed by the limiting plate 45. When squeezed and deformed, the limit plate 45 can drive the sliding rod 441 to move right so that the elastic pad 445 squeezes the inner wall of the opening four 413, thereby preventing the limit plate 45 from deforming too much and affecting the supporting effect on the clamping plate 421. At the same time, when the sliding rod 441 is pulled, the spring two 443 can be pulled, so that the circular tube can be reset after being taken out of the cross bar 411 by the self elastic force of the limit plate 45 and the pulling force of the spring two 443, which is convenient for the subsequent support and fixation of the circular tube again.
