DETAILED DESCRIPTION

[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 As shown in FIG. 3 , an embodiment of the utility model proposes a negative pressure adsorption type tooling fixture, including a base 1, side panels 2 are vertically provided at both ends of the base 1, a first cylinder 3 is provided on the top of the bottom plate, a placement plate 4 is vertically and horizontally provided at the output end of the first cylinder 3, a negative pressure adsorption component is provided on the placement plate 4, clamping blocks 5 are provided on the opposite side walls of the two side panels 2, concave grooves for accommodating the ends of the outer shell are opened on the opposite sides of the two clamping blocks 5, and a buffer component for preventing the outer shell from being deformed is provided in each concave groove, an installation box 6 is provided on the side wall of each side panel 2, and a second cylinder 7 is fixedly provided on the inner wall of each installation box 6, and a first motor 8 is fixedly provided on the output end of each second cylinder 7 after passing through the side panel 2, and the output end of each first motor 8 is fixedly connected to the corresponding clamping block 5. In the present embodiment, each side plate 2 is provided with a through groove, and the two first motors 8 are respectively slidably arranged in the through grooves of the corresponding side plates 2, and the through grooves can guide and support the first motors 8. When clamping the shell, the shell to be sprayed is placed on the placement plate 4, and then the negative pressure adsorption component is started to adsorb the shell, and then the first cylinder 3 is started, and the first cylinder 3 pushes the shell to move upward to a predetermined position, at which time the top surface of the shell can be sprayed, and when the top surface of the shell is sprayed, the two second cylinders 7 are started, and the two second cylinders 7 respectively push the corresponding clamping blocks 5 toward the shell, and finally the two ends of the shell are respectively inserted into the concave grooves of the two clamping blocks 5 and pressed against the buffer component, at which time the negative pressure adsorption component no longer adsorbs the shell and returns to its original position, and the buffer component buffers the end of the shell, and on the premise that the two clamping blocks 5 can clamp the shell, the shell is prevented from bending and deforming due to rigid extrusion contact between the mounting block 16 and the shell, thereby ensuring product quality. Thereafter, the two first motors 8 are started, and the two first motors 8 drive the clamping block 5 to flip 180 degrees, and the first cylinder 3 is started again, and the first cylinder 3 pushes the negative pressure adsorption component on the placement plate 4 to abut against the bottom of the shell after it is flipped 180 degrees, and the negative pressure adsorption component is started again to suck the shell, and now the top of the shell after flipping can be sprayed.

[0019] like Figure 2As shown, further, the buffer assembly includes: buffer springs 9, a plurality of buffer springs 9 are arranged in the concave groove of each clamping block 5, one end of each buffer spring 9 is fixedly connected to the inner wall of the concave groove, and the other end of each buffer spring 9 is fixedly provided with a clamping block 10. When the two second cylinders 7 push the clamping blocks 5 to clamp the outer shell, the two ends of the two outer shells respectively press against the clamping blocks 10 in the concave grooves of the two clamping blocks 5 and squeeze the clamping blocks 10, and the buffer springs 9 shrink under the pressure of the outer shell, providing an elastic force in the direction of the outer shell away from the buffer springs 9, thereby clamping the outer shell and avoiding the clamping block 5 from being rigidly pressed against the outer shell.

[0020] like Figure 3 As shown, further, guide blocks 11 are fixedly provided at both ends of each abutting block 10, and a slide groove 12 is provided on the inner wall of the concave groove for the corresponding guide block 11 to slide. The guide block 11 guides the movement of the abutting block 10 in the concave groove, so that the abutting block 10 moves stably in the concave groove without deviation.

[0021] like Figure 1 As shown in FIG. 3 , further, each side wall of the abutting block 10 away from the buffer spring 9 is provided with a plurality of anti-skid protrusions 13. The anti-skid protrusions 13 increase the friction between the contact surface of the abutting block 10 and the housing to avoid slipping when the housing is clamped.

[0022] like Figure 1 —3, further, the negative pressure adsorption assembly includes: a plurality of suction nozzles 14, one end of each suction nozzle 14 is fixedly arranged on the top of the placement plate, and the other end of each suction nozzle 14 is connected to a vacuum machine 15 through a hose. When working, the vacuum machine 15 is started, and the vacuum machine 15 generates negative pressure to adsorb the shell. In this embodiment, there are three suction nozzles 14, and the shape and angle of the suction nozzle 14 can be adaptively designed as needed to make the suction nozzle 14 more suitable for the surface of the shell.

After the shell is clamped, the driving component is started, and the driving component drives the nozzle 17 to reciprocate along the length direction of the mounting groove, so that the paint sprayed by the nozzle 17 can be evenly coated on the surface of the shell.

[0024] like Figure 3As shown, further, the driving assembly includes: a screw rod 18, the screw rod 18 is horizontally and rotatably arranged in the installation groove, a slider 19 is slidably arranged in the installation groove, the screw rod 18 passes through the slider 19 and is threadedly connected to the slider 19, the slider 19 is fixedly connected to the nozzle 17, and a second motor 20 is arranged after one end of the screw rod 18 passes through the installation groove, and the second motor 20 is fixedly connected to the installation block 16. When the nozzle 17 starts to spray the paint, the second motor 20 is started, and the second motor 20 drives the screw rod 18 to rotate, so that the slider 19 threadedly connected to the screw rod 18 moves along the length direction of the installation groove, thereby driving the nozzle 17 fixedly connected to the slider 19 to reciprocate along the installation groove to spray the surface of the shell.
