DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described below in combination with specific implementation methods. The drawings are only used for exemplary descriptions, and only show schematic diagrams rather than physical drawings, and cannot be understood as limitations of this patent; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0017] The pneumatic clamping mechanism of the utility model is used to connect the crimping die to the working table of the crimping machine. Figure 1-Figure 4 As shown, it includes a base plate 1, a fixed claw 2, a movable claw 3, and a cylinder 4. Two fixed claws 2 are arranged at intervals on the left side of the base plate 1, and the upper part of the fixed claws 2 extends out of the base plate 1. A slide groove 5 is provided in the left and right directions of the middle part of the base plate 1. The movable claw 3 is movably arranged in the slide groove 5, and its upper part extends out of the base plate 1. A spring 6 is provided between the left inner wall of the slide groove 5 and the movable claw 3. Under the action of the spring, the movable claw naturally abuts against the right inner wall of the slide groove. The right inner wall of the slide groove 5 is provided with a through hole 7 to the right; the cylinder 4 is arranged on the right side of the base plate 1 through an adapter plate 8, and the adapter plate plays the role of fixing the cylinder. The telescopic rod of the cylinder 4 passes through the adapter plate 8 and is movably arranged in the through hole 7; the front end of the telescopic rod of the cylinder is connected to a push rod 9, and the push rod 9 is arranged in contact with the right side of the movable claw 3. As shown Figure 1 , Figure 2As shown, the telescopic rod of the cylinder extends to drive the push rod to move to the left, and the push rod pushes the movable claw to move to the left along the slide slot. Under the action of the two fixed claws, the pneumatic clamping mechanism is in a clamping state; the telescopic rod of the cylinder retracts, and under the action of the spring, the movable claw moves to the right along the slide slot, and the pneumatic clamping mechanism is in an open state.

[0018] In this embodiment, the fixing claw is arranged on the left side of the bottom plate. Figure 2 As shown, the left side of the bottom plate 1 is provided with positioning slots 10 at intervals, the lower part of the fixed claw 2 is a rectangular body adapted to the positioning slot 10, the lower part of the fixed claw 2 is vertically arranged in the positioning slot 10 and is locked by bolts, the side of the fixed claw 2 close to the movable claw 3 is inclined to the right and upward to form a first clamping slope 21, the first clamping slope 21 is located above the bottom plate and does not contact the bottom plate, the first clamping slope is adapted to the left side of the crimping die, and can achieve the clamping of the crimping die. By setting the positioning slot, it is ensured that the fixed claw does not move left or right or up and down, and its positioning ensures that it is stable and immovable.

[0019] Further, if Figure 3 As shown, the slide groove 5 is an inverted T-shaped structure slide groove, and the inverted T-shaped structure slide groove runs through the top and bottom surfaces of the bottom plate. The movable claw 3 is an inverted T-shaped block adapted to the inverted T-shaped structure slide groove. The movable claw 3 moves left and right in the T-shaped structure slide groove of the bottom plate. The cooperation between the inverted T-shaped structure slide groove and the inverted T-shaped block ensures that the movable claw does not fall out of the slide groove while moving; the upper part of the movable claw 3 close to the fixed claw 2 is tilted to the left and upward to form a second clamping inclined surface 31, which is located above the bottom plate and does not contact the bottom plate. The second clamping inclined surface 31 is adapted to the right side of the crimping mold. When the movable claw moves to the left side of the slide groove, the second clamping inclined surface abuts against the right side of the crimping mold, exerting a downward pressure on it to achieve the locking of the crimping mold. At the same time, in order to reduce the size of the structure of the movable claw, a rightward-facing recess 32 is firstly provided in the middle of one side of the movable claw close to the fixed claw, and then inclined leftwardly and upwardly to form a second clamping inclined surface 31 .

[0020] Furthermore, since the movable claw structure is relatively small, in order to adapt to the size of the movable claw, such as Figure 2 As shown, the push rod 9 is a convex cylinder, and the side of the push rod close to the movable claw is a boss end 91 with a gradually reduced diameter.

[0021] In addition, a mounting through hole 11 is provided on the base plate 1, and the base plate is fixed on the workbench of the crimping machine by using the mounting through hole, and then the crimping mold is fixed on the base plate. A waste through hole 12 is provided on one side of the base plate 1 close to the fixing claw 2 to facilitate the leakage of waste. The position varies depending on the crimping mold and is not specifically limited.

[0022] In addition, the bottom plate is also provided with a number of other grooves, through grooves, open grooves, etc., for fixing other modules.

[0023] The use process of the utility model is as follows: firstly, the pneumatic clamping mechanism is placed on the working table of the crimping machine, and the bottom plate is fixed by installation, thereby fixing the entire clamping mechanism, and then the crimping die is placed on the bottom plate, with the left side thereof close to the two fixed claws, and then the cylinder is started to move the movable claw to the left, so as to be close to and pressed against the right side of the crimping die.
