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.

[0021] See Figures 1 to 4 In the embodiment of the present utility model, a positioning fixture for processing metal products includes a base 1, a fixed vise 3, a mobile vise 7, an adaptive clamping head 16, a hydraulic telescopic component and a pressure control component; the base 1 is fixedly connected to a fixed frame 2, the fixed vise 3 is fixedly connected to the fixed frame 2, the base 1 is fixedly connected to a slide rail 4, the slide rail 4 is slidably connected to a sliding seat 5, the sliding seat 5 is fixedly connected to a mobile frame 6, the mobile frame 6 is fixedly connected to a mobile vise 7, the mobile vise 7 and the fixed vise 3 cooperate with each other, and a first telescopic pump 10 is installed between the mobile vise 7 and the fixed vise 3; the hydraulic telescopic component is provided with multiple groups, and the multiple groups of hydraulic telescopic components are respectively fixedly connected to the mobile vise 7 and the fixed vise 3, and the adaptive clamping head 16 is rotatably connected to the hydraulic telescopic component. On the output shaft of the contraction component; the pressure control component is connected to the fixed vise 3 and the mobile vise 7, and multiple groups of the hydraulic telescopic components are connected in parallel on the pressure control component. The utility model installs multiple groups of hydraulic telescopic components between the fixed vise 3 and the mobile vise 7, and the multiple groups of hydraulic telescopic components are connected in parallel. At this time, the pressure control component can be used to pressurize and push the multiple groups of hydraulic telescopic components. At this time, since the multiple groups of hydraulic telescopic components are connected in parallel, the thrust generated by each group of hydraulic telescopic components is the same, thereby driving the multiple groups of adaptive clamping heads 16 to extend synchronously and fit and clamp on the outer wall of the metal product, and the holding force of each group of adaptive clamping heads 16 is the same, and then the first telescopic pump 10 is used to drive the mobile vise 7 to move toward the fixed vise 3, thereby tightening and clamping the metal product.

[0022] In one embodiment of the present invention, see Figures 1 to 4The fixed vise 3 is provided with multiple groups of equally spaced slide grooves 8, and the mobile vise 7 is fixedly connected with a sliding bracket 9, which is slidably connected to the slide groove 8. The utility model realizes the relative sliding positioning between the fixed vise 3 and the mobile vise 7 through the sliding connection between the sliding bracket 9 and the slide groove 8. At the same time, the sliding bracket 9 is used to lift the fixed vise 3 and the mobile vise 7, thereby preventing the metal products from falling off between the fixed vise 3 and the mobile vise 7.

[0023] In one embodiment of the present invention, see Figures 1 to 4 The hydraulic telescopic assembly includes a hydraulic cylinder 11 fixedly connected to the mobile clamp 7 and the fixed clamp 3, a piston block 12 is slidably connected in the hydraulic cylinder 11, one end of a connecting rod 13 is fixedly connected to the piston block 12, and the other end of the connecting rod 13 passes through the hydraulic cylinder 11 and is fixedly connected to one side of a rotating connector 15, the adaptive clamping head 16 is rotatably connected to the other side of the rotating connector 15, a spring 14 is provided on one side of the piston block 12, and a first connector 17 is fixedly connected to the tail of the hydraulic cylinder 11. The hydraulic telescopic assembly is controlled by the pressure control assembly. High-pressure hydraulic oil is injected into the hydraulic cylinder 11, and then the piston block 12 is pushed by the high-pressure hydraulic oil. At this time, since multiple groups of hydraulic cylinders 11 are connected in parallel, each group of piston blocks 12 receives the same pushing force. The piston block 12 drives the adaptive clamping head 16 to be elastically ejected through the connecting rod 13. The adaptive clamping head 16 realizes the adaptive fitting and clamping fixation of the metal product surface by the adaptive clamping head 16 through the setting of the rotating connecting head 15, and then realizes multi-point fitting of the metal product through the synchronous hydraulic pressure of multiple groups of adaptive clamping heads 16, and the holding force of multiple groups of adaptive clamping heads 16 is the same.

When the equipment clamps the metal product, the second telescopic pump 23 is first controlled to extend through the control button 25, and the second telescopic pump 23 drives the piston plate 24 to move in the hydraulic cylinder 21, thereby pressurizing the hydraulic oil in the hydraulic cylinder 21, and the pressure is transmitted to the hydraulic cylinder 11 through the hydraulic oil.

[0025] In one embodiment of the present invention, see Figures 1 to 4The outer walls of the mobile vise 7 and the fixed vise 3 are fixedly connected with a main pipe 18, and multiple groups of equally distributed second connecting heads 19 are fixedly connected to the main pipe 18.
