[0026] Embodiment 1
[0027] Reference Figures 1-4 For the first embodiment of the utility model, the embodiment provides a pneumatic clamp, which can realize uniform distribution of clamping force on the workpiece surface and angle adjustment effect during workpiece machining, and comprises,
[0028] The bearing mechanism 100 comprises a support table 101.
[0029] The support table 101 is used to support the clamping mechanism 200.
[0030] The clamping mechanism 200 comprises a mounting assembly 201 fixedly installed on the top of the support table 101 and a driving assembly 202 used in cooperation with the mounting assembly 201.
[0031] It should be noted that the mounting assembly 201 is used to support the driving assembly 202, so that the driving assembly 202 clamps and fixes the workpiece.
[0032] In addition, the overturning mechanism 300 is arranged on both sides of the support table 101.
[0033] It should be further noted that the overturning mechanism 300 can adjust the angle of the workpiece during the machining process through the cooperation between the parts.
[0034] Specifically, the mounting assembly 201 comprises a fixed frame 201a fixedly connected to the top of the support table 101, four support columns 201b arranged in a circumferential array on the outer surface of the fixed frame 201a, and a support plate 201c fixedly connected to the outer surface of the support column 201b.
[0035] The support plate 201c can be supported by the cooperation of the fixed frame 201a and the support column 201b, so that the support plate 201c supports the workpiece.
[0036] Further, the driving assembly 202 comprises a first air cylinder 202a adapted to be installed on the top of the support table 101 and a limiting block 202b fixedly connected to the output end of the first air cylinder 202a. The number of limiting blocks 202b is four, and the four limiting blocks 202b are arranged in a circumferential array on the inner surface of the mounting assembly 201. The four limiting blocks 202b are in sliding contact with the four sides of the inner surface of the fixed frame 201a, respectively.
[0037] The output end of the first air cylinder 202a is fixedly connected to one side of one of the limiting blocks 202b. When the output end of the first air cylinder 202a is extended, it can drive the one limiting block 202b to move linearly on the inner surface of the fixed frame 201a.
[0038] Preferably, the outer surface of the limiting block 202b is fixedly connected with a rotating column 202c, the outer surface of the rotating column 202c is sleeved with a hinged rod 202d, and the inner surface of the hinged rod 202d is in rotating contact with the outer surface of the rotating column 202c.
[0039] When the one limiting block 202b moves linearly, the rotating column 202c at the top of the one limiting block 202b and the hinged rod 202d move synchronously.
[0040] It should be noted that the drive assembly 202 further comprises a rotating disc 202e hinged to the inner surface of the other end of the articulated rod 202d, and a clamp 202f fixedly installed on the top end of the rotating column 202c, and the bottom center of the rotating disc 202e is fixedly installed on the top of the fixed frame 201a through a bearing.
[0041] Wherein, when one of the articulated rods 202d moves linearly, it can drive the rotating disc 202e to rotate, and through the rotating disc 202e, the other articulated rods 202d are driven to rotate synchronously, and through the cooperation of the other articulated rods 202d and the rotating column 202c, the limiting block 202b moves linearly on the inner surface of the fixed frame 201a, so that the four rotating columns 202c simultaneously drive the four clamps 202f to clamp and fix the workpiece, so as to realize the effect that the clamping force is uniformly distributed on the surface of the workpiece.
[0042] Further, the turnover mechanism 300 comprises a first support frame 301 arranged on one side of the support table 101, and a second air cylinder 302 adaptively installed on the outer surface of the first support frame 301.
[0043] Wherein, the first support frame 301 is used to support the second air cylinder 302 and the support table 101.
[0044] Specifically, the output end of the second air cylinder 302 is fixedly connected with a rack plate 303, and the outer surface of the rack plate 303 is engaged with a spur gear 304.
[0045] Wherein, when the output end of the second air cylinder 302 is extended, it can drive the rack plate 303 to move linearly, so that the rack plate 303 drives the spur gear 304 to rotate.
[0046] Preferably, the turnover mechanism 300 further comprises a drive shaft 305 fixedly connected to the inner surface of the spur gear 304, and a second support frame 306 arranged on the other side of the support table 101, and the penetrating end of the drive shaft 305 is fixedly connected with one side of the support table 101, and the other side of the support table 101 is fixedly installed on the outer surface of the second support frame 306 through a bearing.
[0047] Wherein, when the spur gear 304 rotates, it can drive the drive shaft 305 and the support table 101 to rotate synchronously, so as to adjust the angle of the workpiece during machining.
[0048] In use, the output end of the first cylinder 202a is controlled to extend, driving one of the limiting blocks 202b to move linearly on the inner surface of the fixed frame 201a. The top rotating column 202c of the limiting block 202b is driven to move synchronously with the articulated rod 202d, and the articulated rod 202d is driven to drive the rotating disc 202e to rotate. The rotating disc 202e drives the other articulated rods 202d to rotate synchronously, and the other articulated rods 202d drive the limiting blocks 202b to move linearly on the inner surface of the fixed frame 201a in cooperation with the rotating columns 202c. Thus, the four rotating columns 202c drive the four clamps 202f to clamp and fix the workpiece, so as to achieve the effect that the clamping force is evenly distributed on the surface of the workpiece.
[0049] The output end of the second cylinder 302 is controlled to extend, driving the rack plate 303 to move linearly, so that the rack plate 303 drives the spur gear 304 to rotate, and the spur gear 304 drives the driving shaft 305 to rotate synchronously with the support table 101, so as to adjust the angle of the workpiece during the machining process.
[0050] In summary, through the cooperation between the components in the clamping mechanism 200 and the turnover mechanism 300, the clamping force of the clamp 202f can be evenly distributed on the surface of the workpiece, and the angle of the workpiece can be adjusted during the machining process. This can effectively avoid the situation that the clamping force of the clamp 202f is concentrated on one or several points, causing the workpiece to deform or slide due to uneven force. It also avoids constantly adjusting the path of the tool during the machining process, thereby greatly improving the production efficiency of the workpiece machining.
