AI Technical Summary
The internal structure of traditional pneumatic jaws has poor guidance limiting effect on a single slide rail, resulting in insufficient clamping stability. Especially when the clamping jaws are long in mechanical hands dedicated to centerless grinders, obvious shaking affects clamping stability.
Two parallel slide rails are used as the guide shafts, and the cylinder is set between the two slide rails to increase the wheelbase and combine multiple sets of jaw design to improve the guide limit effect and stability.
High rigidity and high stability are achieved under a larger lever ratio, which improves the installation and operation stability and working efficiency of the jaws, and ensures the stability of workpiece pick-up and conveyance.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of gripper mechanisms, and more particularly, to a mechanical pneumatic gripper mechanism. Background Art

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only some, rather than all, of the embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the utility model belong to the scope of protection of the utility model.
[0019] In the description of the present utility model, it should be understood that terms such as "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the utility model.
[0020] Please refer to Figures 1 - 3 As shown, the present utility model is a mechanical pneumatic gripper mechanism, including a left end plate 1 and a right end plate 2. Between the left end plate 1 and the right end plate 2, an upper slide rail 5 and a lower slide rail 6 arranged in parallel are fixedly installed. Between the left end plate 1 and the right end plate 2, a left push plate 3 and a right push plate 4 slidably installed on the upper slide rail 5 and the lower slide rail 6 are also provided. On the inner side of the right push plate 4, a cylinder 7 is fixedly installed. On the telescopic end of the cylinder 7, a push shaft is fixedly installed, and one end of the push shaft is fixedly connected to the inner side of the left push plate 3; at the bottom end of the left push plate 3, a left gripper fixing block 9 is fixedly installed. At the bottom end of the left gripper fixing block 9, a left gripper 11 is fixedly installed. At the bottom end of the right push plate 4, a right gripper fixing block 10 is fixedly installed. At the bottom end of the right gripper fixing block 10, a right gripper 12 corresponding to the left gripper 11 is fixedly installed;
[0021] Specifically, when the mechanical pneumatic gripper mechanism is in use, through the telescoping of the cylinder 7, it can control the left push plate 3 and the right push plate 4 to move in opposite directions along the upper slide rail 5 and the lower slide rail 6 to open or move towards each other to approach, and further drive the left gripper 11 and the right gripper 12 to move in opposite directions to open or move towards each other to approach, and then the workpiece is clamped and conveyed through the left gripper 11 and the right gripper 12; two slide rails, namely the upper slide rail 5 and the lower slide rail 6, are used as guide shafts, improving the stability of the gripper installation and operation, meeting the requirements of high rigidity and high stability under a large leverage ratio, and further making the process of clamping and conveying the workpiece more stable.
[0022] Furthermore, at the bottom ends of the inner sides of the left push plate 3 and the right push plate 4, sliding sleeves 8 are fixedly installed. The two sliding sleeves 8 are respectively slidably installed at both ends of the lower slide rail 6, and the two sliding sleeves 8 are respectively fixedly connected to the left gripper fixing block 9 and the right gripper fixing block 10. By providing the sliding sleeves 8 slidably installed on the lower slide rail 6, the left gripper fixing block 9, the right gripper fixing block 10, the left gripper 11 and the right gripper 12 can be further guided and limited, thereby further improving the stability of the left gripper 11 and the right gripper 12 during movement and operation.
[0023] Furthermore, at the bottom end of the left gripper fixing block 9, a plurality of left grippers 11 evenly distributed at equal intervals are fixedly installed. At the bottom end of the right gripper fixing block 10, a plurality of right grippers 12 corresponding to the left grippers 11 one by one are fixedly installed. By providing multiple groups of mutually cooperating left grippers 11 and right grippers 12, the equipment can clamp and convey multiple workpieces simultaneously during operation, improving the working efficiency of the equipment.
[0024] Furthermore, the air cylinder 7 is arranged between the upper slide rail 5 and the lower slide rail 6. By arranging the air cylinder 7 between the two slide rails, the distance between the two slide rails is increased, thereby enhancing the guiding and limiting effect between the two slide rails and further improving the running stability of the left clamping jaw 11 and the right clamping jaw 12.
[0025] Furthermore, an upper proximity switch 14 is fixedly installed on the inner side surface of the right end plate 2 above the right push plate 4, and an induction shaft 13 capable of triggering the upper proximity switch 14 is fixedly installed at the top of the left push plate 3; a lower proximity switch 15 is also fixedly installed on the inner side surface of the right end plate 2 on one side of the right push plate 4. When the air cylinder 7 drives the left push plate 3 and the right push plate 4 to move towards each other and approach to drive the left clamping jaw 11 and the right clamping jaw 12 to close and clamp, the left push plate 3 drives the induction shaft 13 to move to one side of the upper proximity switch 14, so that the clamping state of the device can be measured through the cooperation of the induction shaft 13 and the upper proximity switch 14. Correspondingly, when the air cylinder 7 drives the left push plate 3 and the right push plate 4 to move in the reverse direction and open to drive the left clamping jaw 11 and the right clamping jaw 12 to release the clamping, the right push plate 4 moves to the right to trigger the lower proximity switch 15, so that the relaxation state of the device can be measured through the cooperation of the right push plate 4 and the lower proximity switch 15.
