Description

Technical Field

[0001] This utility model relates to a clamp, and more particularly to a moving clamp for a pneumatic punch press. Background Technology

[0002] A punch press converts circular motion into linear motion. Powered by a main motor, it drives a flywheel, which in turn drives gears, crankshaft, connecting rods, etc., via a clutch to achieve linear motion of the slide block. The motion from the main motor to the connecting rod is circular motion. Punch presses are widely used in stamping and forming of electronics, communications, computers, home appliances, furniture, transportation vehicles, hardware parts, etc. The workpiece needs to be clamped and fixed by fixtures during the stamping process.

[0003] For example, a pneumatic punch press moving fixture, disclosed in Chinese Patent Publication No. CN221715496U, includes: a device table, on which a movable seat is slidably mounted back and forth; a fixed seat, on which a fixed seat is fixedly connected to the top of the movable seat, and a first limiting block is slidably mounted left and right on the top of the fixed seat; a hydraulic rod, on which a hydraulic rod is mounted on the top right side of the fixed seat, and a second limiting block is fixedly connected to the movable end of the hydraulic rod; and a pneumatic motor body, mounted on the rear side of the top of the device table, on which a motor is mounted, and a shaft is fixedly connected to the output end of the motor, the outer surface of which has a threaded structure. This pneumatic punch press moving fixture is movable, and after the fixture fixes the workpiece, its position can be easily adjusted, allowing the workpiece to be repositioned according to the punching position.

[0004] Some problems were found when using the existing pneumatic punch press moving fixture. First, during the punch press processing, a certain amount of chips and scraps are punched off the material plate. A large amount of chips and residues will stick to the sliding mechanism and screw on the fixed seat, which will affect the sliding of the first limit block. Utility Model Content

[0005] The purpose of this utility model is to provide a moving fixture for a pneumatic punch press to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a movable clamp for a pneumatic punch press, comprising a mounting frame, a plug-in mounting groove on one side of the mounting frame, a collection box slidably mounted in the plug-in mounting groove, a support crossbar symmetrically fixed to the inner wall of the mounting frame near the upper edge, a limiting groove below the support crossbar, a sliding seat above the mounting frame, a limiting slider symmetrically fixed to the lower part of the sliding seat, the limiting slider slidingly engaging with the limiting groove, a clamping cylinder fixed to the top of the sliding seat, a second clamping block fixed to the output end of the clamping cylinder, a first clamping block slidably mounted on the top of the mounting frame, the first clamping block engaging with the clamping cylinder, symmetrical sliding connection grooves below the sliding seat, a first connecting block and a second connecting block symmetrically fixed to the left and right sides of the first clamping block, the first connecting block and the second connecting block slidingly engaging with the sliding connection groove.

[0007] Preferably, a threaded adjusting rod is rotatably installed in one of the limiting slide grooves, and a power motor is fixedly connected to one side of the mounting frame, with the output end of the power motor fixedly connected to one end of the threaded adjusting rod.

[0008] Preferably, a threaded sleeve is embedded in one of the limiting sliders, and the threaded sleeve is threadedly engaged with the power motor.

[0009] Preferably, a displacement handle is fixedly connected to one side of the collection box, a limiting groove is formed on one side of the collection box, a return spring is fixedly connected in the limiting groove, a limiting pin is fixedly connected to the other end of the return spring, and a displacement handle is fixedly connected to the limiting pin.

[0010] Preferably, a limiting hole is provided at the top of the insertion mounting groove, and the limiting hole cooperates with the limiting pin.

[0011] Preferably, both the first connecting block and the second connecting block are fixedly connected to a limiting vertical block, and each of the two limiting vertical blocks is fixedly connected to a limiting protrusion tooth on one side. A limiting slot is formed in the sliding connecting groove, and a limiting tooth groove is formed on the inner wall of one side of the limiting slot. The limiting tooth groove and the limiting protrusion tooth cooperate with each other.

[0012] Preferably, a nut is embedded in the second connecting block, and a fixing bolt is installed on the internal thread of the nut.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting the sliding connection structure of the sliding seat and the first clamping block below the support crossbar and the sliding seat respectively, it is difficult for debris on the sliding seat to enter the sliding connection structure. This can prevent debris from entering the slide groove during the later use of the punch press, which would affect the sliding adjustment of the sliding seat and the first clamping block.

[0015] 2. By inserting the collection box into the plug-in mounting slot, the collection box is located inside the mounting frame. The debris generated during the processing will fall into the collection box and be collected, making it easier to clean the clamped debris later.

[0016] 3. The connecting arm of the second connecting block has a U-shaped structure, which allows the first clamping block to move to the left by a certain distance relative to the sliding seat. At this time, the limiting tooth will be driven out of the limiting tooth groove, thereby releasing the restriction on the first clamping block. The first clamping block can be adjusted back and forth, and the front and back position of the workpiece can be adjusted. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a movable fixture for a pneumatic punch press, including a mounting frame 1. A mounting groove 105 is provided on one side of the mounting frame 1, and a collection box 2 is slidably installed in the mounting groove 105. Supporting crossbars 101 are symmetrically fixed to the inner wall of the mounting frame 1 near the upper edge. A limiting groove 102 is provided below the supporting crossbars 101. A sliding seat 3 is provided above the mounting frame 1, and limiting sliders 301 are symmetrically fixed to the lower part of the sliding seat 3. The limiting sliders 301 and the limiting groove 102... 02 Sliding fit, a clamping cylinder 5 is fixedly connected to the sliding seat 3, and a second clamping block 501 is fixedly connected to the output end of the clamping cylinder 5. A first clamping block 4 is slidably connected and installed on the mounting frame 1. The first clamping block 4 and the clamping cylinder 5 cooperate with each other. A sliding connection groove 303 is symmetrically opened on the bottom of the sliding seat 3. A first connecting block 401 and a second connecting block 402 are symmetrically fixed to the left and right sides of the first clamping block 4, respectively. The first connecting block 401 and the second connecting block 402 are slidably fitted with the sliding connection groove 303.

[0026] In this embodiment, by inserting the collection box 2 into the insertion mounting slot 105, the collection box 2 is located inside the mounting frame 1. The debris generated during processing will fall into the collection box 2 and be collected, making it easier to clean the clamped debris later. The limiting slider 301 and the limiting slide groove 102 slide together, thereby sliding the sliding seat 3 above the mounting frame 1. The first connecting block 401 and the second connecting block 402 cooperate with the sliding connecting groove 303 to slide the first clamping block 4 on the sliding seat 3. The limiting slide groove 102 and the sliding connecting groove 303 are both opened at the bottom, making it difficult for debris on the sliding seat 3 to enter the limiting slide groove 102 and the sliding connecting groove 303. This can avoid the problem of debris entering the groove during the later use of the punch press, which would affect the sliding adjustment of the sliding seat 3 and the first clamping block 4.

[0027] In order to achieve the purpose of adjusting the position of the sliding seat 3, the device adopts the following technical solution: a threaded adjusting rod 103 is rotatably installed in one of the limiting slide grooves 102, a power motor 104 is fixedly connected to one side of the mounting frame 1, the output end of the power motor 104 is fixedly connected to one end of the threaded adjusting rod 103, and a threaded sleeve block 302 is embedded in one of the limiting sliders 301, and the threaded sleeve block 302 is threadedly engaged with the power motor 104.

[0028] By activating the plug-in mounting slot 105, the power motor 104 can be driven to rotate. The power motor 104 is threadedly engaged with the threaded sleeve block 302. The rotation of the power motor 104 can drive the limit slider 301 to move. The movement of the limit slider 301 can drive the sliding seat 3 to move. The position of the sliding seat 3 can be adjusted left and right using the plug-in mounting slot 105.

[0029] To achieve the purpose of fixing the collection box 2, the device adopts the following technical solution: a displacement handle 201 is fixedly connected to one side of the collection box 2, a limiting groove 202 is opened on one side of the collection box 2, a return spring 203 is fixedly connected in the limiting groove 202, a limiting pin 204 is fixedly connected to the other end of the return spring 203, a displacement handle 205 is fixedly connected to the limiting pin 204, and a limiting hole 106 is opened at the top of the insertion mounting groove 105, and the limiting hole 106 and the limiting pin 204 cooperate with each other.

[0030] The displacement handle 201 allows the operator to easily pull out the collection box 2. The return spring 203 can provide a certain pushing force to the limit pin 204. When the limit pin 204 is pushed, it will insert into the limit hole 106, thereby fixing the collection box 2 inside the insertion mounting slot 105. The displacement handle 205 can be used to drive the limit pin 204 to move.

[0031] To achieve the purpose of fixing the first clamping block 4, the device adopts the following technical solution: a limiting vertical block 403 is fixedly connected to both the first connecting block 401 and the second connecting block 402, and a limiting tooth 404 is fixedly connected to one side of each of the two limiting vertical blocks 403. A limiting slot 304 is opened in the sliding connecting groove 303, and a limiting tooth groove 305 is opened on the inner wall of one side of the limiting slot 304. The limiting tooth groove 305 and the limiting tooth 404 cooperate with each other. A nut 405 is embedded in the second connecting block 402, and a fixing bolt 406 is installed in the thread of the nut 405.

[0032] By engaging the limiting tooth groove 305 and the limiting protrusion 404, the limiting vertical block 403 can be fixed inside the limiting slot 304, thereby restricting the forward and backward movement of the first clamping block 4. The connecting arm of the second connecting block 402 has a U-shaped structure, allowing the first clamping block 4 to move a certain distance to the left relative to the sliding seat 3. The first connecting block 401 and the second connecting block 402 can synchronously drive the limiting vertical block 403 to move. The movement of the limiting vertical block 403 will drive the limiting protrusion 404 to move, at which point the limiting protrusion 404 will move out of the limiting tooth groove 305, releasing the restriction on the first clamping block 4. Figure 6As shown, the end of the fixing bolt 406 is located inside the U-shaped structure of the second connecting block 402. Under the restriction state of the first clamping block 4, the first clamping block 4 can be restricted from moving to the left. When it is necessary to adjust the front and rear position of the first clamping block 4, the end of the fixing bolt 406 is unscrewed. At this time, the U-shaped structure on the connecting arm of the second connecting block 402 is in a hollow state, and the first clamping block 4 can be moved to drive the limiting tooth 404 out of the limiting tooth groove 305.

[0033] The working principle and usage process of this utility model are as follows: When in use, place the workpiece to be clamped on the sliding seat 3, start the clamping cylinder 5 to drive the second clamping block 501 to move, and use the second clamping block 501 and the first clamping block 4 to clamp and fix the workpiece on the sliding seat 3. Start the plug-in mounting groove 105 to drive the sliding seat 3 to move, thereby adjusting the position of the workpiece left and right. When it is necessary to adjust the front and back position of the workpiece, the fixing bolt 406 needs to be unscrewed before clamping. At this time, the first clamping block 4 can be moved to the left, so that the limiting protrusion 404 moves out of the limiting tooth groove 305. At this time, the position of the first clamping block 4 can be adjusted back and forth. Clamp the workpiece again to adjust the front and back position of the workpiece.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
