[0022] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0023] like Figures 1 to 4 As shown, a gripper cylinder device includes a cylinder body 1, a first cylinder arm 101, a second cylinder arm 102 and a speed regulating valve 103. The first cylinder arm 101 and the second cylinder arm 102 are connected to the cylinder body 1. A pair of speed regulating valves 103 are arranged on the side wall of the cylinder body 1. The speed regulating valve 103 is used to drive the first cylinder arm 101 and the second cylinder arm 102 to open or close. The speed regulating valve 103 drives the first cylinder arm 101 and the second cylinder arm 102 to open at an angle of 0°-90°.

[0024] The first cylinder arm 101 is connected to a first cylinder clamp, the second cylinder arm 102 is connected to a second clamp 105, the first clamp 104 and the second clamp 105 are mirror-imaged, the first clamp 104 is provided with a first clamping portion 106, the second clamp 105 is provided with a second clamping portion 107, the first clamping portion 106 and the second clamping portion 107 are U-shaped, when the first cylinder arm 101 and the second cylinder arm 102 are closed, the first clamp 104 and the second clamp 105 are also closed at the same time, at which time the first clamping portion 106 and the second clamping portion 107 form a clamping area 108.

[0025] Further, the first clamping jaw 104 is also connected to a first pressure rod assembly 2, the first pressure rod assembly 2 includes a pressure rod body 201 and a pressure rod bracket 205, the pressure rod bracket 205 is provided with a mounting hole 206 that runs through the upper and lower parts, and a perforated round table 207 is also provided in the mounting hole 206, the perforated round table 207 divides the mounting hole 206 into an upper mounting hole 208 and a lower mounting hole 210, the pressure rod body 201 runs through the upper mounting hole 208 and the lower mounting hole 210, the pressure rod bracket 205 is also provided with a slide groove 209, the slide groove 209 is connected to the upper mounting hole 208, the first pressure rod assembly 2 also includes a pressure rod head 203 and a spring 211, the pressure rod head 203 is connected to the top of the pressure rod body 201, and the top of the pressure rod head 203 is arranged with an inclined surface that is higher on the left and lower on the right (with an inclined surface that is higher on the left and lower on the right) Figure 3 The pressure rod head 203 is also provided with a slider 204 on the side wall, and the slider 204 is arranged in the slide groove 209. The pressure rod head 203 slides up and down in the upper mounting hole 208 through the slide groove 209. The spring 211 is arranged in the upper mounting hole 208 and is sleeved on the pressure rod body 201. The top surface of the spring 211 abuts against the bottom surface of the pressure rod head 203, and the bottom surface of the spring 211 abuts against the top surface of the perforated cone 207. The pressure rod head 203 can be reset by the spring 211. The first pressure rod assembly 2 also includes a bushing 212, which is arranged in the lower mounting hole 210. The top surface of the bushing 212 abuts against the bottom surface of the perforated cone 207. The bushing 212 is sleeved on the pressure rod body 201. The bottom end of the pressure rod body 201 is also provided with a limiting ring 202. When the pressure rod body 201 is reset by the spring 211, the top of the limiting ring 202 abuts against the bottom of the bushing 212 to prevent the pressure rod body 201 from detaching from the limiting ring 202 of the bushing 212 after being reset upward. At the same time, the limiting ring 202 also prevents the bushing 212 from falling directly from the lower mounting hole 210.

[0026] Furthermore, the second clamping jaw 105 is connected to a second pressure rod assembly 3, and the second pressure rod assembly 3 includes a mounting frame 301 and a rolling bearing 304. The mounting frame 301 includes a first connecting rod 302 and a second connecting rod 303, wherein the first connecting rod 302 and the second connecting rod 303 are connected, and the rolling bearing 304 is connected to the second connecting rod 303. Specifically, one end of the first connecting rod 302 is connected to the second clamping jaw 105, and the end of the first connecting rod 302 away from the second clamping jaw 105 is connected to the second connecting rod 303, and the end of the second connecting rod 303 away from the first connecting rod 302 is connected to the rolling bearing 304, the first connecting rod 302 is perpendicular to the second clamping jaw 105, and the second connecting rod 303 is perpendicular to the first connecting rod 302.

[0027] During use, when the speed regulating valve 103 drives the first cylinder arm 101 and the second cylinder arm 102 to close, the first clamp 104 and the second clamp 105 also close accordingly. At this time, the first pressure rod assembly 2 cooperates with the second pressure rod assembly 3. Specifically, the rolling bearing 304 in the second pressure rod assembly 3 moves from the low surface position of the pressure rod head 203 to the high surface position of the pressure rod head 203. The rolling bearing 304 will give downward pressure to the pressure rod head 203, and the spring 211 will be compressed to make the slider 204 on the pressure rod head 203 slide downward in the slide groove 209. The pressure rod head 203 drives the pressure rod body 201 to move downward, so that the pressure rod body 201 reduces the gap between it and the material. When the speed regulating valve 103 drives the first cylinder arm 101 and the second cylinder arm 102 to separate, the first clamp 104 and the second clamp 105 are also separated, and the rolling bearing 304 will no longer apply downward pressure to the pressure rod head 203. At this time, the spring 211 will rebound under the action of elastic force, and the spring 211 pushes the slider 204 on the pressure rod head 203 to slide upward in the slide groove 209, driving the pressure rod body 201 to move upward until the top of the limit ring 202 abuts against the bottom of the bushing 212.
