The motor 7 is fixedly connected to both sides of the bottom end of the outer wall of the connecting plate 5.

[0033] Reference Figure 2-Figure 4 The surface of the connecting plate 5 is provided with two groups of clamping components 6, and the clamping components 6 include a fixed seat 61, and the surface of the fixed seat 61 is provided with three groups of linear guide grooves, and the inner wall of the linear guide groove is slidably connected with a clamping block 62. The linear guide groove on the surface of the fixed seat 61 is set so that the clamping block 62 can only move back and forth on the inner wall of the linear guide groove, and the three groups of clamping blocks 62 can clamp and fix the mechanical product from the inside or from the outside according to different mechanical products. The inner wall of the fixed seat 61 is rotatably connected with a rotating disk 63, and the rotating disk 63 The surface of the rotating disk 63 is provided with three groups of arc guide grooves, and the clamping blocks 62 are slidably connected to the inner walls of the arc guide grooves of the rotating disk 63. When the rotating disk 63 rotates, the bottom ends of the three groups of clamping blocks 62 will move on the inner walls of the arc guide grooves, so as to get closer to or move away from each other. The outer wall of the rotating disk 63 is fixedly connected with a fixing block 64, and the outer side wall of the fixing seat 61 is provided with a sliding groove. The fixing block 64 is slidably connected to the inner wall of the sliding groove of the fixing seat 61. Through the movement of the fixing block 64, the rotating disk 63 can be driven to rotate on the inner wall of the fixing seat 61.

[0034] Reference Figure 4The inner wall of the fixed block 64 is elastically connected with a pressing block 66 through a limiting spring 65. One end of the limiting spring 65 is fixedly connected to the bottom end of the inner wall of the fixed block 64, and the other end of the limiting spring 65 is fixedly connected to the bottom end of the outer wall of the pressing block 66. The function of the limiting spring 65 is to automatically reset the pressing block 66 after it is pressed and moved. The pressing block 66 is slidably connected to the inner wall of the fixed block 64. The inner wall of the fixed seat 61 is provided with multiple groups of slots, and the pressing block 66 is plugged into the inner wall of the slot. The shape of the pressing block 66 is a concave shape, one end of which is convenient for the staff to operate and press, and the other end is engaged with the slot of the fixed seat 61. The engagement between the two fixes the rotating disk 63 at multiple positions of the inner wall of the fixed seat 61.

[0035] Reference Figure 1 and Figure 5 The rotating assembly 4 includes a fixed column 41, the inner wall of the top of the fixed column 41 is elastically connected to the limit ball 43 through a reset spring 42, the bottom end of the limit ball 43 is provided with a cylindrical shape, and the top end is provided with a spherical shape that fits the ball groove at the bottom end of the connecting plate 5. The fixed column 41 is fixedly connected to the bottom end of the inner wall of the body 1, and the connecting plate 5 is rotatably connected to the top of the outer wall of the fixed column 41. The connecting plate 5 rotates around the rotation center point of the fixed column 41, so that the two sets of fixed seats 61 can be switched, so that the mechanical product can be quickly replaced. One end of the reset spring 42 The inner wall at the top of the fixed column 41 is fixedly connected, and the other end of the reset spring 42 is fixedly connected to the bottom end of the outer wall of the limiting ball 43. The function of the reset spring 42 is to reset the moving position of the limiting ball 43. The limiting ball 43 is slidably connected to the inner wall of the fixed column 41. Two sets of ball grooves are provided at the bottom end of the outer wall of the connecting plate 5. The top of the outer wall of the limiting ball 43 contacts the inner wall of the ball groove. The contact between the two fixes the connecting plate 5 in the rotating position of the top of the fixed column 41, and the fixed connecting plate 5 between the two will not rotate without the influence of external force.

[0036] Working principle: When processing a mechanical product, the mechanical product can first be placed between the three groups of clamping blocks 62 on the surfaces of the two groups of fixed seats 61. At this time, the fixed block 64 can be grasped and the pressing block 66 can be pressed to move downward on the inner wall of the fixed block 64. At the same time, during the descent of the pressing block 66, the limit spring 65 will be elastically compressed, and the other end of the concave shape of the pressing block 66 will be separated from the card slot at the current position of the fixed seat 61. At this time, the fixed block 64 can be rotated to drive the rotating disk 63 to rotate on the inner wall of the fixed seat 61. During the rotation of the rotating disk 63, the clamping blocks 62 in the three groups of arc-shaped guide grooves on its surface will be mutually aligned with the inner wall of the arc-shaped guide groove. They are close to each other, and because the clamping block 62 also slides inside the linear guide groove of the fixed seat 61, the clamping block 62 can only move linearly in the linear guide groove of the fixed seat 61 so as to close together to clamp and fix the mechanical product. At this time, the button 66 is released and it will be elastically acted upon by the limit spring 65, restoring it to its initial position to be plugged into the slot of the current position of the fixed seat 61, thereby fixing the position of the fixed block 64, and also fixing the positions of the rotating disk 63 and the three groups of clamping blocks 62 on its inner wall. The rotating disk 63 rotates left or right, and can be clamped from the inside or from the outside according to the shape of the mechanical product.

[0037] At this time, the paint storage device can be controlled by the electronic control device to allow the paint to pass through the external pipe 3 and then be sprayed out from the nozzle 2, so as to paint the mechanical product. At the same time, the motor 7 at the painting end of the connecting plate 5 can be started so that its output shaft drives the fixed seat 61 to rotate, so that the mechanical product can be painted at multiple angles. After one group of products is painted, the connecting plate 5 can be directly rotated to rotate around the center point of the fixed column 41, so that the mechanical products on the surface of the other group of fixed seats 61 can enter the interior of the machine body 1 for painting. After the painting is completed, the fixed seat 61 at one end will The mechanical product is driven out from the inside of the machine body 1, so that it is convenient for the staff to disassemble it and replace it with a new mechanical product. At the same time, when the connecting plate 5 is rotating, the inner wall of the ball groove at its bottom end will squeeze the spherical end of the top of the limiting ball 43, and squeeze the limiting ball 43 to move downward on the inner wall of the fixing column 41 until the position of the next set of ball grooves is reached. The limiting ball 43 will be elastically acted upon by the reset spring 42 to restore it to its initial position, thereby contacting the inner wall of the ball groove at the current position of the connecting plate 5 to fix the position of the connecting plate 5, and the two are in contact, and the connecting plate 5 will not rotate without the influence of external force.
