Description

Technical Field

[0001] The utility model relates to the technical field of workpiece clamping, in particular to an adjustable special-shaped workpiece clamping tool. Background Art

[0002] Machining refers to the process of changing the external dimensions or performance of a workpiece through a mechanical device. It can be divided into cutting and pressure processing according to the difference in processing methods. In the production process, any process that changes the shape, size, position and properties of the production object to make it a finished product or semi-finished product is called a process. It is the main part of the production process. The process can be divided into casting, forging, stamping, welding, machining, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the machining process of parts and the assembly process of the machine.

[0003] In traditional clamping tooling, the clamping mechanism located on the processing platform mostly keeps a fixed position with the processing platform. However, due to the raised and bent parts on the surface of the special-shaped aluminum plate, the clamping mechanism in the clamping tool can only press the flat part of the special-shaped aluminum plate that fits the surface of the processing platform. The operator needs to manually move the position of the special-shaped aluminum plate on the processing platform to adjust the clamping position. The special-shaped aluminum plate is large in size and inconvenient to operate. At the same time, it is easy to cause the end of the special-shaped aluminum plate to move out of the processing platform, reducing the stability of the clamping of the special-shaped aluminum plate.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 In this embodiment, an adjustable special-shaped workpiece clamping tool includes a support leg 1, and an adjustment movement mechanism is provided on the top of the support leg 1.

[0023] In embodiment one, the adjustment and movement mechanism includes an operating table 2 fixedly mounted on the top of the support leg 1, two brake motors 3 are fixedly mounted on the left side of the operating table 2, and a reciprocating screw 4 rotatably connected to the operating table 2 is fixedly mounted on the output shaft of the brake motor 3. A movable slot is provided on the left side of the operating table 2, and the reciprocating screw 4 is rotatably connected to the operating table 2 through the movable slot, which facilitates the rotation of the reciprocating screw 4.

[0024] Among them, the outer side of the reciprocating screw 4 is threadedly connected with two threaded blocks 5, and the outer side of the reciprocating screw 4 is provided with two sections of threaded grooves in opposite directions. The threaded block 5 is threadedly connected to the reciprocating screw 4 through the threaded groove, which facilitates the movement of the threaded block 5 on the reciprocating screw 4. The top of the threaded block 5 is fixedly installed with a support rod 6 that is slidably connected to the operating table 2. A limiting groove is provided on the top of the operating table 2. The support rod 6 is slidably connected to the operating table 2 through the limiting groove, which facilitates the limiting of the support rod 6.

[0025] In this embodiment, a mounting plate 7 is fixedly installed on the top of the support rod 6, and a base plate 8 is movably connected to the top of the mounting plate 7. A fixing frame 9 is fixedly installed on the top of the base plate 8, and a pressure plate 10 is rotatably connected to the inner side of the fixing frame 9. A return spring 11 is fixedly connected between the base plate 8 and the pressure plate 10. An auxiliary component is provided on the outside of the base plate 8, and a clamping plate 12 is fixedly installed on one side of the base plate 8 and the pressure plate 10. A slider 13 slidably connected to the mounting plate 7 is fixedly installed on the bottom of the base plate 8. A sliding groove is provided on the top of the mounting plate 7, and the slider 13 is slidably connected to the mounting plate 7 through the sliding groove, which helps the slider 13 to slide and move.

[0026] In embodiment 2, a limiting component is provided on the top of the base plate 8, and a fixing plate 14 is fixedly installed on one side of the base plate 8. Threaded holes are provided on the top of the mounting plate 7 and the inside of the fixing plate 14. The fixing bolts 15 are threadedly connected to the mounting plate 7 and the fixing plate 14 through the threaded holes, which helps to fix and disassemble the fixing plate 14 and the mounting plate 7. The internal thread of the fixing plate 14 is connected to the fixing bolts 15 threadedly connected to the mounting plate 7.

[0027] It should be noted that the adjustable special-shaped workpiece clamping tool, through the setting of the adjustment and moving mechanism, uses the brake motor 3 and the reciprocating screw 4 to drive the two threaded blocks 5 away from or close to each other, thereby driving the base plate, fixed frame 9 and pressure plate 10 at the top to move relative to each other, and can slide on the mounting plate 7 through the slider 13, and then the fixing bolt 15 can be rotated and fixed into the interior of the fixing plate 14 and the mounting plate 7 to fix the clamps on both sides, which is convenient for use with workpieces of different sizes. Using the reset spring 11, pressure plate 10, and base plate 8, the clamping plate 12 can be driven to approach the clamping plate 12 at the bottom and clamp the workpiece. The reset spring 11 can provide elastic tension to maintain the stability of the clamping.

[0028] The working principle of the above embodiment is:

[0029] When using this adjustable special-shaped workpiece clamping tool, the distance size is first adjusted according to the size to be clamped, and the brake motor 3 is started. The brake motor 3 drives the reciprocating screw 4 to rotate, and the two threaded blocks 5 on the outside of the reciprocating screw 4 begin to move closer to or away from each other under the limit of the support rod 6, thereby driving the two base plates, the fixing frame 9 and the pressure plate 10 to move relative to each other, and then the slider 13 can be used to slide on the mounting plate 7, and then the fixing bolts 15 can be rotated and fixed into the inside of the fixing plate 14 and the mounting plate 7 to fix the clamps on both sides, and the four clamps are adjusted to the size suitable for the workpiece to be clamped, which is convenient for adaptation. It is used for workpieces of different sizes, and then the pressure plate 10 can be pressed. The pressure plate 10 compresses the reset spring 11, and the pressure plate 10 rotates on the inside of the fixed frame 9. At this time, the base plate 8 is fixed, and the two clamping plates 12 are away from each other. Then the four corner areas of the workpiece can be placed between the four base plates 8 and the pressure plate 10, and then the pressure plate 10 is slowly released. The reset spring 11 automatically resets and drives the pressure plate 10 to reset and move, so that the pressure plate 10 drives the clamping plate 12 to approach the clamping plate 12 at the bottom and clamp the workpiece. The reset spring 11 can provide elastic tension to maintain the stability of clamping, which greatly improves the flexibility of clamping and fixing.
