[0028] Example:

[0029] Reference Figure 1-6 This embodiment provides a tool for processing burrs of a car door handle skeleton, which mainly includes a processing table 1, the processing table 1 is provided with a conveying mechanism 3 and a grinding mechanism, the skeleton workpiece 10 is arranged on the conveying mechanism 3 for conveying, and the conveying mechanism 3 is preferably as follows Figure 1 In the guide rail transmission shown, a carrier platform 11 is provided on the guide rail to drive the skeleton workpiece 10 to move. A conveyor belt type transmission device can also be selected.

[0030] like Figure 2 , Figure 3 As shown, the processing table 1 is also provided with a cleaning mechanism, which includes a switch structure, and the switch structure includes an elastic reset member 8. A linkage member is provided between the grinding mechanism and the switch structure. When the grinding mechanism approaches and acts on the skeleton workpiece 10, the grinding mechanism is suitable for driving the linkage member to open the switch structure so that the cleaning mechanism is automatically turned on. After the grinding mechanism is reset, the switch structure is suitable for automatically closing by the recovery of the elastic reset member 8. Figure 2 The figure shows a frame 2, a lifting part 4, a central control part and a grinding head 5. The lifting part 4 is generally a lifting mechanism such as a cylinder that is easy to automatically control. The central control part and the grinding head 5 are the main parts of the grinding mechanism, which can make the grinding head 5 have the characteristics of rotation as needed, such as Figure 2The linkage part is arranged on the central control part. The central control part and the grinding head 5 are driven by the lifting part 4 to move up and down when in use. After the skeleton workpiece 10 reaches the preset grinding position, the lifting part 4 drives the grinding head 5 to descend to fit with the skeleton workpiece 10 for grinding. At this time, the linkage part installed on the central control part also descends to open the opening structure, thereby starting the cleaning mechanism for automatic cleaning, and the elastic reset member 8 is also compressed accordingly; and after the grinding is completed, the lifting part 4 drives the grinding head 5 to rise, and at this time the elastic reset member 8 is reset to make the switch mechanism automatically closed, so that the cleaning mechanism automatically stops, thereby completing the functions of automatic cleaning and automatic stopping. Compared with the prior art, the cleaning mechanism of this embodiment only performs real-time cleaning during grinding, with good cleaning effect, and automatically stops cleaning after grinding is completed, without manual operation.

[0031] like Figure 2 , Figure 3 As shown, the linkage is hingedly mounted on the grinding mechanism, and the switch structure includes an action site; when the linkage rotates to match the action site, the grinding mechanism is suitable for linkage with the switch structure; when the linkage is offset from the action site, the grinding mechanism and the switch structure are not linked. In this embodiment, the cleaning mechanism can freely choose whether to be turned on when in use, that is, when the grinding mechanism and the switch structure are linked, the cleaning mechanism will be turned on during grinding; and when the two are not linked, the cleaning mechanism will not be turned on.

[0032] like Figure 2 , Figure 3 As shown, a preferred embodiment scheme of the cleaning mechanism is proposed. The cleaning mechanism includes a cleaning frame 7 connected to a water source and a cleaning head 9 facing the grinding position of the skeleton workpiece 10. The cleaning frame 7 and the cleaning head 9 are connected to form a water flow channel. A valve core 13 is provided in the water flow channel. The valve core 13 includes a cleaning channel 14 parallel to the water flow channel. A movable rod 6 is inserted perpendicular to the valve core 13. The movable rod 6 includes a side hole 16 parallel to the direction of the water flow channel. The linkage is suitable for acting on the movable rod 6. In the initial state, the elastic reset member 8 acts on the movable rod 6 to stagger the side hole 16 and the cleaning channel 14. When the grinding mechanism is close to the skeleton workpiece 10, the linkage is suitable for moving the movable rod 6 downward, the elastic reset member 8 is compressed, and the side hole 16 is connected to the cleaning channel 14 at the same time, so that the cleaning head 9 works. In this embodiment, by controlling whether the side hole 16 corresponds to the cleaning channel 14, whether the cleaning mechanism can spray the cleaning agent at the cleaning head 9 is controlled. Obviously, a certain water pressure is required at the water source. The cleaning head 9 is as shown in FIG. Figure 3 As shown, it is tilted downward toward the grinding position of the skeleton workpiece 10, so that the cleaning agent can be sprayed at the correct position during cleaning, which helps to improve the cleaning effect.

[0033] Since the movable rod 6 and the valve core 13 are plug-in connected, in order to ensure the sealing performance, Figure 4As shown, the valve core 13 is provided with a sealing groove, and a sealing gasket 15 is provided in the sealing groove. Specifically, sealing gaskets 15 are provided on both the upper and lower sides of the valve core 13 in the figure, wherein the inner side of the sealing gasket 15 is tightly fitted with the outer wall of the movable rod 6, which can effectively ensure the sealing of the valve core 13 and the connection between the movable rod 6 and the cleaning rack 7.

[0034] In order to make the cooperation between the linkage rod 12 and the movable rod 6 have a certain stability, the top of the movable rod 6 is hemispherical, the linkage part is the linkage rod 12, and the bottom of the linkage rod 12 is provided with a circular groove corresponding to the position of the movable rod 6. When the linkage rod 12 rotates to cooperate with the movable rod 6, the hemispherical top of the movable rod 6 and the circular groove cooperate with each other. When interacting with each other, through the cooperation of the circular groove and the hemispherical top of the movable rod 6, the linkage rod 12 and the movable rod 6 are not easy to slip off each other under the action of external force.

[0035] In this embodiment, refer to Figure 4 As shown, the elastic reset member 8 is preferably configured as a spring, a limit portion 17 is provided at the bottom of the movable rod 6, and the bottom of the spring is arranged on the conveying mechanism. In the initial state, the top of the spring acts on the limit portion 17 so that the limit portion 17 is in close contact with the bottom surface of the cleaning rack 7. At this time, the side hole 16 is misaligned with the cleaning channel 14. Figure 4 The figure shows the initial state, at which the top surface of the limit portion 17 is in contact with the bottom surface of the cleaning rack 7. During grinding, the linkage rod 12 is the limit portion 17. Figure 4 The position of the cleaning mechanism moves down and the spring is compressed at the same time, so the spring recovers after the grinding is completed, thereby ensuring that the cleaning mechanism can work stably.

[0036] like Figure 5 As shown, the cross-section of the side hole 16 is a long groove shape, and the cross-sectional height of the side hole 16 can be further set to be larger than the diameter of the cleaning channel 14. With this setting, during the downward movement of the movable rod 6, there are more processes in which the side hole 16 can form a passage with the cleaning channel 14, which allows the cleaning mechanism to have a longer opening time at the beginning of grinding, thereby ensuring the cleaning effect.

[0037] A plurality of grinding mechanisms are arranged at intervals along the conveying direction of the conveying mechanism 3, and the plurality of grinding mechanisms are provided with independent control systems. Each grinding mechanism is independently controlled by a cleaning mechanism, so that a plurality of skeleton workpieces 10 can be ground simultaneously during processing.

[0038] like Figure 2 As shown, there are two cleaning mechanisms on both sides of the grinding mechanism, and two corresponding linkage rods 12 are provided. Obviously, two cleaning mechanisms are provided on both sides of a grinding mechanism, and the two cleaning mechanisms are simultaneously controlled to be opened or closed by the two corresponding linkage rods 12.

[0039] Another linkage embodiment is proposed below: the switch structure includes a travel switch, the linkage member is set as a linkage rod 12, the cleaning head 9 is provided with an electrically controlled water spray component, when the grinding mechanism approaches the skeleton workpiece 10, the linkage rod 12 acts on the travel switch, and the water spray component is turned on when the travel switch is triggered. In this embodiment, the spray component in the cleaning mechanism is controlled to start by triggering the travel switch, and automatic opening and closing can also be completed.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
