[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] A clamp fixing device comprises a base 1, a cavity is arranged inside the base 1, two groups of through grooves 2 are symmetrically opened on the top of the base 1, sliders 3 are slidably connected inside the two groups of through grooves 2, and mold frames 4 are fixedly connected to the tops of the two groups of sliders 3, and clamping components 5 for positioning plate-like workpieces are arranged on the tops of the two groups of mold frames 4, respectively. Two groups of clamping components 6 for positioning tubular workpieces are symmetrically arranged on the side walls of the two groups of mold frames 4, and an adjusting component 7 for adjusting the distance between the two groups of mold frames 4 is arranged inside the cavity of the base 1. The utility model has a compact structure, can meet the clamping requirements of plate-like workpieces and tubular workpieces at the same time, has a wide range of application, and can improve the application range of the clamp and the workpiece processing efficiency;

[0026] The clamping assembly 5 includes a first electric push rod 501, which is fixedly mounted on the top of the molded frame 4, and one end of the telescopic end of the first electric push rod 501 penetrates the molded frame 4 and is fixedly connected to a pressing plate 502;

[0027] Specifically, when the plate-like workpiece needs to be positioned, the plate-like workpiece can be placed on the inner bottom of the mold frame 4, and then the pressing plate 502 is pushed downward by the telescopic end of the first electric push rod 501 to press and position the plate-like workpiece;

[0028] It also includes an anti-skid pad 8, which is fixedly bonded to the bottom of the pressing plate 502, and the bottom of the anti-skid pad 8 is arranged in a corrugated shape. By arranging the anti-skid pad 8, the plate-shaped workpiece that is pressed and positioned can be prevented from sliding and deviating, which is beneficial to improving the stability of subsequent processing thereof;

[0029] The clamping assembly 6 includes an L-shaped positioning plate 601, which is fixedly mounted on one side wall of the shaped frame 4, and a second electric push rod 602 is fixedly mounted on one inner wall of the L-shaped positioning plate 601, and one end of the telescopic end of the second electric push rod 602 passes through the L-shaped positioning plate 601 and is fixedly mounted with a connecting plate 603, and a clamping block 604 is fixedly connected to one side wall of the connecting plate 603, and a V-shaped groove 605 is opened on one side of the clamping block 604;

[0030] Specifically, when the tubular workpiece needs to be positioned, the two ends of the tubular workpiece can be placed on the inner bottom of the mold frame 4 respectively, and then the connecting plate 603 is driven to move by the telescopic end of the second electric push rod 602, so that the two groups of clamping blocks 604 can be driven to move toward the direction of the tubular workpiece, and then the tubular workpiece can be clamped and positioned;

[0031] It should be noted that the design of the V-groove 605 can well adapt to the shape of the tubular workpiece. Since the tubular workpiece has a circular cross-section, the inner wall of the V-groove 605 can fit closely with the outer surface of the tubular workpiece, thereby achieving more stable and precise clamping.

[0032] A slide groove 9 is provided on one side wall of the shaped frame 4, and two sets of connecting plates 603 are respectively slidably connected to the inside of the slide groove 9. By providing the slide groove 9, the connecting plate 603 is limited, making its operation process more stable;

[0035] The bottoms of the two groups of sliders 3 are respectively fixedly connected to the tops of the two groups of moving blocks 703, and the two groups of moving blocks 703 are symmetrically arranged. When the moving blocks 703 move, the sliders 3 can be driven to move synchronously, that is, the distance between the two groups of mold frames 4 can be adjusted by the two groups of sliders 3, and workpieces of different lengths can be clamped and positioned or pressed and positioned, which is conducive to further improving the flexibility of the clamp;

[0036] The driving motor 702 is fixedly mounted on a side wall of the base 1 , one end of the output shaft of the driving motor 702 is fixedly connected to one end of the bidirectional screw rod 701 , and the driving motor 702 is configured as a forward and reverse stepping motor.

[0037] Working principle: When the utility model is used, the bidirectional screw rod 701 is first driven to rotate by the output shaft of the driving motor 702, thereby driving the two sets of moving blocks 703 to reciprocate along the axial direction of the bidirectional screw rod 701, and then the distance between the two sets of mold frames 4 can be adjusted by the two sets of sliders 3. After the two sets of mold frames 4 are moved to the appropriate position, when it is necessary to position the plate-like workpiece, the plate-like workpiece can be placed on the inner bottom of the mold frame 4 first, and then the pressure plate 502 is pushed downward by the telescopic end of the first electric push rod 501, so that the plate-like workpiece can be pressed and positioned. When it is necessary to position the tubular workpiece, the two ends of the tubular workpiece can be placed on the inner bottom of the mold frame 4 respectively, and then the connecting plate 603 is driven to move by the telescopic end of the second electric push rod 602, thereby driving the two sets of clamping blocks 604 to move toward the direction of the tubular workpiece, and then the tubular workpiece can be clamped and positioned.
