Description

Technical Field

[0001] This utility model relates to the technical field of a vise, and in particular to a pneumatic vise quick-locking structure. The jaws and the inverted T-shaped slider are integrally manufactured. Only a fixed pin is needed to push the jaws and the pin into the opening of the inclined slot. When the positioning hole is positioned with the spring positioning ball, the piston can quickly pull the two jaws to clamp the workpiece, achieving fast and precise locking. Background Technology

[0002] Referring to the known Taiwan Patent Application No. TW112200594, "Visor Structure," although it can also be used to clamp workpieces, each clamping unit 30 requires a cover plate 33 to be locked on the drive seat 31, and a movable jaw 32 to be locked on the drive seat 31. The structure is very complex. The first step in assembling the clamping unit 30 onto the vise is to remove the screws, first remove the span plate 34, and then remove the fixing bolt 521. Only in this way can the two clamping units 30, along with the clamping slider 40, be pulled out of the slide groove 22. Finally, the two clamping units 30 can be disassembled. Therefore, disassembly and replacement are quite difficult. Furthermore, the movable jaw 32, cover plate 33, and drive seat 31 of the clamping unit 30 are independent and need to be fixed together by screws to form a clamping unit 30 for use, which is quite inconvenient. The prior art has considerable room for improvement.

[0003] Therefore, in view of the problems existing in the above-mentioned conventional structures, how to develop a more ideal and practical innovative structure is what consumers eagerly expect, and it is also the goal and direction that relevant businesses must strive to achieve in their research and development.

[0004] In view of this, based on years of experience in manufacturing, developing and designing related products, the designer of this case has designed and carefully evaluated the above objectives, and finally obtained this utility model with practicality. Utility Model Content

[0005] The main purpose of this utility model is to provide a quick-locking structure for a pneumatic vise. Its jaws and inverted T-shaped slider are manufactured as one piece. Only a fixed pin is needed to push the jaws and the pin into the opening of the inclined slot. When the positioning hole is positioned with the spring positioning ball, the two jaws can be quickly pulled by the piston to clamp the workpiece, achieving fast and precise locking.

[0006] To achieve the above objectives, this utility model provides a pneumatic vise quick-locking structure, characterized in that it comprises:

[0007] A vise body, the vise body having a cylinder chamber with a downward opening inside, the vise body having an inverted T-shaped slide, and a through hole in the center of the vise body leading to the cylinder chamber;

[0028] A piston 30 is slidably disposed in the cylinder chamber 11 and can be driven by pressurized gas to move upward or downward. A piston rod 31 is provided on the piston 30 and can pass through the through hole 13.

[0029] A plurality of elastic elements 40 are disposed between the top surface of the piston 30 and the top surface of the cylinder chamber 11, so that the piston 30 can be pressed down under normal conditions;

[0030] Each of the two grippers 50 and 60 has an inverted T-shaped slider 51 and 61 at its bottom, which slides linearly in the inverted T-shaped slide rail 12. Each of the two inverted T-shaped sliders 51 and 61 has a working groove 511 and 611 on its adjacent surface. A pin 52 and 62 are fixedly mounted transversely at the working groove 511 and 611 of each gripper 50 and 60.
