[0022] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of the clamping device provided by the present utility model; Figure 2 for Figure 1 A schematic structural diagram of the clamping assembly shown;

[0024] Figure 3 for Figure 2 An enlarged structural diagram of point A is shown; Figure 4 for Figure 1 A schematic diagram of the structure of the control assembly shown. A clamping device includes a base plate 1, a support table 2 is fixedly connected to the top of the base plate 1, and a milling machine 3 is fixedly connected to the top of the base plate 1;

[0025] In the specific implementation process, Figure 1 、 Figure 2 and Figure 3 As shown, the clamping assembly 4 is arranged on the top of the support platform 2, and the clamping assembly 4 includes a mounting plate 41, a limiting rod 42, a first spring 43 and a first clamping plate 44. The top of the support platform 2 is provided with a mounting plate 41, the inner side of the mounting plate 41 is slidingly connected to the limiting rod 42, the outer side of the limiting rod 42 is provided with a first spring 43, and one end of the limiting rod 42 is fixedly connected to the first clamping plate 44.

[0026] A second guide groove 6 is formed on the top of the support platform 2 , and a first cylinder 7 is fixedly connected to the top of the support platform 2 .

[0027] A slider 8 is slidably connected to the inner side of the second guide groove 6 , a second clamping plate 9 is fixedly connected to the top of the slider 8 , and an anti-slip pad 10 is fixedly connected to one side of the second clamping plate 9 .

[0028] A support base 11 is fixedly connected to the top of the support platform 2 , and a first connecting rod 12 is provided on the inner side of the support base 11 .

[0029] One end of the first connecting rod 12 is fixedly connected to the piston rod of the first cylinder 7 , and a second spring 13 is welded to one side of the support seat 11 .

[0030] One end of the first connecting rod 12 is fixedly connected to a fixing block 14 , and one side of the fixing block 14 is fixedly connected to one side of the second clamping plate 9 .

[0031] It should be noted that the support platform 2 and the milling machine 3 are supported and fixed by the base plate 1, a through slot is provided on the top of the support platform 2, and the two mounting plates 41 are both mounted and fixed on the top of the support platform 2. When the two limit rods 42 are controlled and pulled respectively, the first clamping plate 44 is driven to move under the support of the mounting plate 41, so that the distance between the two first clamping plates 44 can be adjusted as needed. When the limit rod 42 is relaxed, the first clamping plate 44 is driven to reset under the action of the first spring 43. The cooperation of the two first clamping plates 44 facilitates the clamping and limiting of the front and rear sides of the workpiece. The two support seats 11 facilitate the support of the two first connecting rods 12 respectively. Driven by the first cylinder 7, the first connecting rod 12 drives the fixed block 14 to move, and drives the second clamping plate 9 to move through the fixed block 14. The movement of the second clamping plate 9 drives the slider 8 at its bottom to slide under the limit of the second guide groove 6, which is beneficial to improving the stability of the operation of the second clamping plate 9. By adjusting the distance between the two second clamping plates 9 as needed, it is convenient to clamp both sides of the workpiece, enhance the fixing effect, and effectively avoid displacement during processing. Under the action of the second spring 13, the operation of the fixed block 14 is buffered, effectively avoiding the fixed block 14 from colliding with the support seat 11 when moving toward the support seat 11. The first clamping plate 44 and the second clamping plate 9 are both installed with anti-slip pads 10 on the side close to the workpiece to enhance the friction in contact with the workpiece and improve the stability to a certain extent.

[0032] refer to Figure 1 and Figure 4 As shown, the control component 5 is arranged on the inner side of the support platform 2. The control component 5 includes a placement plate 51 and a first guide groove 52. The placement plate 51 is arranged on the inner side of the support platform 2, and the first guide groove 52 is opened on the top of the placement plate 51.

[0033] The control assembly 5 further includes a connecting frame 53 and a support rod 54 . The bottom of the placement plate 51 is fixedly connected to the connecting frame 53 , and the inner side of the connecting frame 53 is slidably connected to the support rod 54 .

[0034] The top of the base plate 1 is fixedly connected to the second cylinder 15, the piston rod of the second cylinder 15 is fixedly connected to the second connecting rod 16, one end of the second connecting rod 16 is fixedly connected to the bottom of the placement plate 51, the top of the base plate 1 is fixedly connected to one end of the support rod 54, and the top of the inner cavity of the support platform 2 is fixedly connected to the other end of the support rod 54.

[0035] It should be noted that: the placement plate 51 is used to facilitate the placement of the workpiece to be processed, and the first guide groove 52 and the second guide groove 6 are on the same horizontal line, which is convenient for the second clamping plate 9 to drive the slider 8 to operate. When the workpiece processing is completed, the two first cylinders 7 control the two second clamping plates 9 to relax the restrictions on both sides of the workpiece, pull the limit rod 42, so that the limit rod 42 drives the first clamping plate 44 to move, and then relaxes the front and rear restrictions of the workpiece. Under the drive of the second cylinder 15, the second connecting rod 16 drives the placement plate 51 to descend, and at the same time, the two connecting frames 53 slide under the limit of the support rod 54, thereby enhancing the stability of the placement plate 51 when it is lifted and lowered, so that the placement plate 51 is lowered to the inner cavity of the support table 2, which is convenient for the staff to keep their arms away from the tool of the milling machine 3 to take out the workpiece, thereby improving the safety effect.

[0036] The working principle of a clamping device provided by the utility model is as follows:

[0037] When in use, the placing plate 51 is placed on the slot of the support table 2, and the placing plate 51 is supported by the second connecting rod 16 and the two connecting frames 53, so that the height of the placing plate 51 is flush with the support table 2, and the first guide slot 52 and the second guide slot 6 are at the same horizontal line. According to the size of the workpiece, the mounting plate 41 and the first clamping plate 44 of corresponding size are installed, so that the length of the first clamping plate 44 is slightly smaller than the length of the workpiece. Under the support of the mounting plate 41, the limit rod 42 is pulled, so that the limit rod 42 drives the first clamping plate 44 to move, thereby increasing the distance between the two first clamping plates 44 and providing space for placing the workpiece. The workpiece to be processed is placed on the placing plate 51, and under the drive of the first cylinder 7, the first connecting rod 12 drives the fixing block 14 and the second clamping plate 9 to move under the support of the support seat 11. At the same time, the second clamping plate 9 drives the slider 8 to slide under the limit of the second guide slot 6 and the first guide slot 52, thereby improving the stability of the operation. The second clamping plate 9 drives the anti-slip pad 10 to clamp the two sides of the workpiece, and the pull on the limit rod 42 is released. Under the action of the first spring 43, the first clamping plate 44 is driven to reset, which is convenient for clamping the front and rear sides of the workpiece, thereby achieving clamping and fixing the workpiece around to enhance the stability. After the workpiece is processed, the first cylinder 7 controls the second clamping plate 9 to relax the fixation on both sides of the workpiece, and pulls the limit rod 42, so that the limit rod 42 drives the first clamping plate 44 to move toward the mounting plate 41, thereby loosening the limit on the front and rear of the workpiece. Under the drive of the second cylinder 15, the second connecting rod 16 drives the placing plate 51 to descend, and at the same time drives the two connecting frames 53 to slide under the limit of the two support rods 54, thereby enhancing the stability of the placing plate 51 lifting and lowering, so that the placing plate 51 is lowered to the inner cavity of the support table 2, which is convenient for the staff to take out the workpiece, and at the same time, the fingers and arms are away from the first clamping plate 44, the second clamping plate 9 and the tool of the milling machine 3, thereby improving the safety effect.
