Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to an adaptive clamping device for irregularly shaped workpieces. Background Technology

[0002] When manufacturing and processing irregularly shaped workpieces, it is necessary to clamp the workpieces to facilitate processing operations. When clamping irregularly shaped workpieces, pneumatic clamps or corresponding workpiece clamps are often used to clamp them in order to fix the irregularly shaped workpieces.

[0003] Because irregular workpieces have complex shapes and irregular surfaces, existing clamping devices are unable to automatically adjust to the surface undulations of irregular workpieces, resulting in poor adaptability and affecting the clamping effect. Furthermore, irregular workpieces have less contact surface during clamping, and existing clamping devices are not convenient for providing lateral support to the sides of the workpieces when clamping irregular workpieces, resulting in unstable clamping and affecting the fixing effect. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides an adaptive clamping device for irregularly shaped workpieces, which can automatically adjust according to the surface undulations of the irregularly shaped workpiece to improve adaptability and provide lateral support to the side of the workpiece to make the clamping more stable, thereby enhancing the fixing effect.

[0005] Technical solution: An adaptive clamping device for irregularly shaped workpieces, comprising:

[0006] A mounting plate with two grooves;

[0007] Two first electric push rods are fixed to the bottom of the mounting plate;

[0008] A movable plate fixed between the telescopic ends of the two first electric push rods;

[0009] A mounting box fixed to a mounting plate;

[0010] A movable box fixed to a movable plate;

[0011] Adaptive components are mounted on the fixed box and the movable box;

[0012] Side abutment components are mounted on the mounting plate and the movable plate.

[0013] As an improvement to the above solution, the adaptation component includes: several sleeves fixed to the inner wall of the fixed box or the movable box, each sleeve having a sliding rod slidably connected to it, and a first compression spring connecting the sliding rod to the sleeve. The sliding rod and the first compression spring on one sleeve form a group, and there are several groups of adaptation components; two second electric push rods fixed to the fixed box and the movable box respectively; and a movable frame fixed to the telescopic end of each of the two electric push rods respectively.

[0014] As an improvement to the above solution, the sliding rod is provided with several slots.

[0015] As an improvement to the above solution, the side abutment assembly includes: two side plates slidably connected to two grooves on the mounting plate; a third compression spring connected between each of the two side plates and the mounting plate; abutment plates slidably connected to the two side plates respectively; two second compression springs connected between the two abutment plates and the two side plates respectively; two rotating rods respectively; and two pressing plates fixed to the moving plate.

[0016] As an improvement to the above solution, one side of the extrusion plate has an inclined structure.

[0017] Beneficial effects:

[0018] 1. The surface of the irregularly shaped workpiece will press against the sliding rod, and the sliding rod will slide accordingly according to the shape of the irregularly shaped workpiece surface. Under the action of the first compression spring, the sliding rod will clamp the workpiece.

[0019] 2. As the moving frame moves, it contacts the sliding rod and applies lateral pressure to lock the sliding rod. This allows for corresponding adjustments based on the surface undulations of the irregularly shaped workpiece, adapting to different workpiece shapes and enhancing the clamping effect. Simultaneously, the movement of the two side plates causes the abutment plate to move, contacting the side of the irregularly shaped workpiece. The continued movement of the pressing plate further drives the side plates to move, compressing the second compression spring. The second compression spring applies pressure to the abutment plate, thus applying pressure to the side of the irregularly shaped workpiece, resulting in more stable clamping.

[0027] 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.

[0028] Example 1: An adaptive clamping device for irregularly shaped workpieces, such as Figures 1-6 As shown, it includes:

[0029] Mounting plate 1 with two grooves;

[0030] Two first electric push rods 2 are fixed to the bottom of the mounting plate 1;

[0031] A movable plate 3 is fixed between the telescopic ends of the two first electric push rods 2;

[0032] The mounting box 4 is fixedly attached to the mounting plate 1;

[0033] The movable box 5 is fixed to the movable plate 3;

[0034] Adaptive component 6 is mounted on fixed box 4 and movable box 5;

[0035] Side abutment components are mounted on mounting plate 1 and movable plate 3.

[0036] The adaptation component 6 includes: a plurality of sleeves 61 fixed to the inner wall of the fixed box 4 or the movable box 5, each sleeve 61 having a sliding rod 62 slidably connected thereto, and a first compression spring 63 connecting the sliding rod 62 and the sleeve 61. The sliding rod 62 and the first compression spring 63 on one sleeve 61 form a group, and there are several groups of adaptation components 6; two second electric push rods 7 fixed to the fixed box 4 and the movable box 5 respectively; and movable frames 8 fixed to the telescopic ends of the two electric push rods respectively.

[0037] The sliding rod 62 is provided with several slots, which are used to facilitate fixing.

[0038] The side abutment assembly includes: two side plates 9 slidably connected to two slide grooves on the mounting plate 1, the two side plates 9 being arranged in opposite directions; a third compression spring 13 connecting each of the two side plates 9 to the mounting plate 1; abutment plates 10 slidably connected to the two side plates 9 respectively; two second compression springs 11 connecting each of the two abutment plates 10 to the two side plates 9 respectively; two rotating rods 12 respectively rotatably connected to the two rotating rods; and two pressing plates 14 fixed to the moving plate 3.

[0039] The extrusion plate 14 has one inclined surface, which is used to move the side plate 9.

[0040] Initially, the telescopic end of the first electric push rod 2 is extended. When it is necessary to clamp an irregularly shaped workpiece, the operator first places the workpiece on the mounting plate 1, between the fixed box 4 and the movable box 5. Then, the telescopic end of the first electric push rod 2 is retracted, causing the movable plate 3 to move. As the movable plate 3 moves, it also causes the movable box 5 to move closer to the fixed box 4. As the movable box 5 moves, the sliding rod 62 will contact the surface of the irregularly shaped workpiece. Then, the movable box 5 continues to move, and the surface of the irregularly shaped workpiece will abut against the sliding rod 62. At the same time, the sliding rod 62 will slide according to the shape of the irregularly shaped workpiece surface. Under the action of a compression spring 63, the sliding rod 62 clamps the workpiece. Then, the operator pauses the first electric push rod 2 and controls the extension end of the second electric push rod 7 to extend. The extension end of the second electric push rod 7 drives the moving frame 8 to move. As the moving frame 8 moves, it contacts the sliding rod 62 and applies lateral pressure to the sliding rod 62, locking it. This allows for corresponding adjustments based on the surface undulations of the irregularly shaped workpiece to adapt to different irregularly shaped workpieces, thereby enhancing the clamping effect. Simultaneously, the moving plate 3 drives the two pressing plates 14 to move. As the pressing plate 14 moves, it presses the two rotating rods 12 through the inclined surface of the pressing plate 14, causing the two side plates 9 to move closer to each other. The third compression spring 13 is compressed. The movement of the two side plates 9 also drives the abutment plate 10 to move. As the abutment plate 10 moves, it comes into contact with the side of the irregular workpiece. The pressing plate 14 continues to move, causing the side plates 9 to continue moving. The side plates 9 continue to move, pressing the second compression spring 11. The second compression spring 11 applies pressure to the abutment plate 10, which in turn applies pressure to the side of the irregular workpiece, making the clamping more stable and thus enhancing the fixing effect on the irregular workpiece. The processing is completed. Then, the staff controls the extension end of the first electric push rod 2 to extend. The extension end of the first electric push rod 2 will drive the moving box 5 and the pressing plate 14 to reset. At the same time, the resetting of the moving box 5 will drive the sleeve 61 to reset. Then the first compression spring 63 will reset. The moving box 5 continues to reset and the sliding rod 62 will disengage from the irregular workpiece. At the same time, the resetting of the pressing plate 14 will stop pressing the rotating rod 12. The resetting of the third compression spring 13 will drive the side plate 9 to reset and stop pressing the second compression spring 11. After the side plate 9 resets a certain distance, it will drive the abutment plate 10 to reset, thereby releasing the irregular workpiece. The staff can then take out the irregular workpiece.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
