Description

Technical Field

[0001] The present invention relates to the field of automated production, and in particular to a cylinder clamping and grasping mechanism with adjustable clamping force. Background Art

[0002] A pneumatic clamping mechanism utilizes a pneumatic cylinder as a power source, providing stable gripping of workpieces via jaws. Its operating principle is based on pneumatic transmission technology. When the gas pressure within the cylinder changes, the piston reciprocates within the cylinder, driving the opening and closing of the jaws. In automated production lines, rapid positioning and stable transfer of workpieces are key to improving production efficiency. Traditional fixed-force clamping mechanisms often struggle to adapt to workpieces of varying sizes, shapes, and materials, resulting in unstable clamping or damage to the workpiece.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 3 As shown, this embodiment discloses a cylinder clamping and grasping mechanism with adjustable clamping force, including a base plate 1, an adjustment seat 2 is fixed on the top surface of the base plate 1, and a left cylinder 3 and a right cylinder 4 are respectively provided on both sides of the adjustment seat 2, and the bodies of the left cylinder 3 and the right cylinder 4 are both installed and fixed on the base plate 1.

[0030] The telescopic end of the left cylinder 3 is connected to the left push head block 5, the bottom of the left push head block 5 is connected to the left slide 6, and at least one left clamping plate 7 is provided at the bottom of the left slide 6; the telescopic end of the right cylinder 4 is connected to the right push head block 8, the bottom of the right push head block 8 is connected to the right slide 9, and at least one right clamping plate 10 is provided at the bottom of the right slide 9; the left clamping plate 7 and the right clamping plate 10 correspond to each other in a one-to-one manner.

[0031] An adjustable left limit rod 11 is provided on the adjustment seat 2 at the position corresponding to the left push head block 5, and the left limit rod 11 is limited and matched with the left push head block 5; an adjustable right limit rod 12 is provided on the adjustment seat 2 at the position corresponding to the right push head block 8, and the right limit rod 12 is limited and matched with the right push head block 8.

[0032] The working principle of the present invention is:

[0033] The left clamping plate 7 and the right clamping plate 10 are in a separated state. When the left cylinder 3 and the right cylinder 4 work at the same time, the left push head block 5 connected to the output shaft of the left cylinder 3 drives the left slide 6 to move, and the right push head block 8 connected to the output shaft of the right cylinder 4 drives the right slide 9 to move. The left clamping plate 7 and its corresponding right clamping plate 10 are close to each other, thereby realizing the clamping action of the object (such as Figure 2As shown in the figure, the left push head block 5 and the right push head block 8 are in contact with the left limit rod 11 and the right limit rod 12 respectively, completing the buffering effect during the clamping process. At the same time, by slightly adjusting the left limit rod 11 and the right limit rod 12, the limit position of the left push head block 5 and the right push head block 8 can be adjusted, and then the size of the clamping force can be adjusted (the tightness during the clamping process can be adjusted). It should be noted that when the left limit rod 11 and the right limit rod 12 are adjusted over a large distance, the left clamping plate 7 and the right clamping plate 10 can be clamped to adapt to workpieces of different sizes and shapes.

[0034] In this embodiment, the left limiting rod 11 and the right limiting rod 12 are both threaded rods, and are connected to the adjustment base 2 through a threaded structure. The limiting ends of the left limiting rod 11 and the right limiting rod 12 are both provided with a nylon plug 13, which provides a certain buffering effect on the left push head block 5 and the right push head block 8 to prevent direct metal contact and collision.

[0035] like Figures 4 to 6 As shown, the right skateboard 9 includes two spaced apart plate bodies 901, and the area between the two plate bodies 901 is provided with a left skateboard 6; the top of the plate body 901 is connected to the base plate 1 through the right guide rail slider assembly 15; the top of the left skateboard 6 is connected to the base plate 1 through the left guide rail slider assembly 16.

[0036] The right guide rail slider assembly 15 and the left guide rail slider assembly 16 have the same structure, both including a guide rail and a slider. The guide rail part is fixed to the bottom of the base plate 1, and the slider part is fixed to the plate body 901 and the left slide plate 6.

[0037] In order to adapt to the split structure of the right slide plate 9, the right push head block 8 and the right clamping plate 10 are door-shaped as a whole, and their two ends are fixedly connected to the plate body 901. The right slide plate 9 and the left slide plate 6 adopt a hollow weight reduction design, which is light and strong.

[0038] like Figure 7 As shown, a suspension frame 14 is provided on the top surface of the base plate 1. The suspension frame 14 comprises a cross-shaped suspension seat 1401, and the suspension seat 1401 is provided with four pad columns 1402. The suspension seat 1401, the pad columns 1402 and the base plate 1 are fixed together by bolts.

[0039] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
