[0002] Tooling, namely process equipment, refers to the general term for various tools used in the manufacturing process, including cutting tools, jigs, dies, measuring tools, inspection tools, auxiliary tools, fitter tools, workbench fixtures, etc. A tooling fixture is a mechanical device used to fix and position workpieces in industrial production. It usually consists of a clamping device and a supporting device. The clamping device can tightly fix the workpiece on the workbench, and the supporting device can provide the necessary supporting force to ensure that the workpiece does not move or loosen during the processing.

[0003] In the patent CN202222540421.6, with the patent name of a quick positioning and clamping tooling and a machining center, a first support table and a second support table are respectively fixed at both ends of the upper surface of the base to form a clamping space, and a chip removal inclined surface is arranged on the surface of the base to guide and remove the generated iron chips and coolant. However, the first support table and the second support table are only clamped through the clamping space and cannot be adjusted according to the shapes of different workpieces. For workpieces such as bent pipe-shaped workpieces, the clamping is not firm enough, and the iron chips and coolant discharged through the chip removal inclined surface are directly discharged onto the processing table, making it inconvenient to clean.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-6 As shown, the present invention provides the following technical solution: A quick positioning and clamping tooling, including a base 1. Two relatively movable moving seats 5 are installed on the top of the base 1. Turntables 4 are rotatably arranged on the tops of the two moving seats 5. Clamping devices are installed on the tops of the two turntables 4. The clamping device includes a clamping cylinder 8, a clamping assembly 9 and a clamping plate 10. Openings 81 are provided on the opposite sides of the two clamping cylinders 8. A U-shaped clamping groove is provided on the clamping assembly 9, and springs 91 are installed on both sides of the inner wall of the U-shaped clamping groove. Fixing plates 92 are installed at the ends of the two springs 91. A chip removal inclined plane 12 is provided on the top surface of the base 1. A clamping area is formed between the two moving seats 5. The chip removal inclined plane 12 is arranged in the clamping area, and waste boxes 6 are installed on both sides of the base 1.

[0025] In view of the above, when using this quick positioning and clamping tooling, the two moving seats 5 drive the turntables 4 to move towards the clamping area, and the workpiece is clamped by the clamping device. The iron chips and waste liquid generated during the machining of the workpiece fall on the chip removal inclined plane 12 and flow into the waste box 6 through the chip removal inclined plane 12 for storage;

[0026] When the present invention clamps a plate workpiece, as Figure 7 shown, rotate the turntable 4 to rotate the two clamping plates 10 to be placed opposite to each other. Place the plate workpiece to be machined between the two clamping plates 10. Drive the clamping plates 10 to move towards the clamping area through the moving seat 5 until the clamping plates 10 clamp the plate workpiece stably;

[0027] When the present invention clamps a workpiece with a cylindrical structure, rotate the turntable 4 to rotate the two clamping cylinders 8 to be placed opposite to each other. Align the cylindrical workpiece to be machined with the opening 81. While the moving seat 5 drives the clamping cylinders 8 to move towards the clamping area, both ends of the cylindrical workpiece are placed in the clamping cylinders 8 from the opening 81 until the clamping cylinders 8 clamp the cylindrical workpiece stably;

[0028] When the workpiece with a bent pipe structure is clamped, the turntable 4 is rotated to rotate the two clamping assemblies 9 to be placed opposite to each other. The moving seat 5 drives the clamping assembly 9 to move towards the clamping area until the clamping area between the two clamping assemblies 9 is available for placing the bent pipe workpiece. Then, the bent pipe workpiece to be processed is placed in the U-shaped clamping groove on the clamping assembly 9 and fixed by the fixing plate 92.

[0029] In addition, as Figures 1-2 shown, in the present utility model, two mounting plates 3 are further installed on the top of the base 1. Hydraulic push rods 2 are installed on both of the two mounting plates 3. The telescopic ends of the two hydraulic push rods 2 are respectively fixedly connected to the two moving seats 5;

[0030] A motor 11 is installed inside the moving seat 5. The driving end of the motor 11 is rotationally connected to the turntable 4. A rotating groove matching the turntable 4 is provided on the top of the moving seat 5;

[0031] Two sliders 51 are provided at the bottom of the moving seat 5. Two sliding grooves 7 matching the two sliders 51 are formed on the top of the base 1.

[0032] In view of the above, during clamping, the hydraulic push rod 2 and the motor 11 are electrically connected to the controller of the external processing machine. The hydraulic push rod 2 is used to push the moving seat 5 towards the clamping area. Then, the slider 51 at the bottom of the moving seat 5 slides in the sliding groove 7 to facilitate the movement of the moving seat 5. When clamping different workpieces, the motor 11 is started, and the motor 11 drives the turntable 4 to rotate inside the moving seat 5, so as to adjust the clamping cylinder 8, the clamping assembly 9 and the clamping plate 10 on the turntable 4 to the use position. By moving the moving seat 5 for clamping, the workpiece can be quickly positioned, and the use is more convenient.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
