[0026] The preferred embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0027] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0028] The present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0029] The specific implementation process of the utility model is as follows:

[0030] like Figures 1 to 3As shown, a processing equipment for surface treatment of parts includes a machine tool, a workbench 1 arranged on the machine tool, and at least one movable processing head installed above one side of the workbench 1. The multiple movable processing heads include a spindle box 3, and the spindle box 3 includes a spindle 4 extending downward and a nozzle (not shown) for spraying cutting fluid on the spindle 4.

[0031] It also includes a shielding mechanism, which includes air outlet slots 5 arranged around the main shaft 4, and the air outlet slots 5 are used to spray compressed gas in the direction of the workbench 1. A carrying platform 9 for carrying parts is provided below the main shaft 4, and the carrying platform 9 is provided with a working area 91. The area of ​​the working area 91 is smaller than the area defined by the air outlet slots 5, and the working area 91 is used to place parts to be processed.

[0032] A plurality of air outlet holes 510 are arranged in the air outlet slot 5, and the plurality of air outlet holes 510 are connected to a ventilation cavity. The ventilation cavity is arranged in the spindle housing 3, and the ventilation cavity is connected to an air pump through a connecting pipe.

[0033] The compressed gas sprayed downward from the air outlet slot 5 can form a wind screen 6 around the main shaft 4 for blocking the cutting fluid, which can intercept the cutting fluid and impurities generated when the main shaft 4 rotates at a high speed to cut the glass, and flow them away from the bottom of the main shaft 4. On the one hand, it reduces the splashing of cutting fluid and impurities that may affect the surrounding glass; on the other hand, it also collects the cutting fluid flow obtained from processing the glass, so that the generated impurities can be more easily washed away.

[0034] The shielding mechanism is also provided with a flow control valve for adjusting the compressed gas outlet volume and a solenoid valve for controlling the start or shut down of the compressed gas. One end of the solenoid valve is connected to the power controller, and the other end is connected to the flow control valve through a connecting pipe. One end of the air inlet of the flow control valve is connected to the solenoid valve through a connecting pipe, and one end of the air outlet is connected to the air outlet slot 5 through a connecting pipe.

[0035] Flow control valves are used to adjust the flow of compressed gas and can also be used for diversion. Flow control valves are valves that control the flow of a throttle port by changing the size of the throttle port under a certain pressure difference. Solenoid valves use electromagnetic control and can be direct-acting solenoid valves, distributed direct-acting solenoid valves, or pilot-operated solenoid valves. When the power is on, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when the power is off, the electromagnetic force disappears, and the spring presses the closing member against the valve seat, and the valve closes. After the solenoid valve switch is started, compressed gas can be generated by compressing the gas in a closed system, so that the movement of the gas can be controlled by controlling the on and off current of the electromagnet.

[0036] In some embodiments, a plurality of guide air ducts (not shown) may preferably be provided in the ventilation cavity, and the guide air ducts are used to evenly distribute the wind in the ventilation cavity to a plurality of air outlet holes 510 .

[0037] In some embodiments, the air outlet holes 510 have a preset length and width, the length direction of the air outlet holes 510 is parallel to the edge of the support platform, and the spacing between adjacent air outlet holes is smaller than the length of the air outlet holes. When a plurality of air outlet holes spray air at the same time, a dense wind screen with uniform thickness can be formed around the main shaft, ensuring the light transmittance and density of the wind screen, and preventing the cutting fluid from splashing to the outside of the support platform.

[0038] In some embodiments, the cross-sectional shape of a plurality of air outlet holes 510 is wedge-shaped, and the plurality of air outlet holes 510 are evenly arranged. The wedge-shaped air outlet holes 510 prevent the compressed air from dispersing to the inside and outside when spraying downward, but instead disperses crosswise along the wind screen surface, thereby forming good airtightness and avoiding shielding blind spots, while ensuring the resistance effect of the wind screen.

[0039] In some embodiments, an atomized liquid adsorption device is provided between the main shaft 4 and the shielding mechanism, and the atomized liquid adsorption device includes a suction head located in the space defined by the through groove, and the suction head is arranged above the supporting platform 9. The suction head is connected to the vacuum device through a pipeline. The suction head can absorb the mist and harmful gas generated during the cutting fluid injection process in the space defined by the through groove, thereby preventing the mist from gathering inside the wind screen 6 to affect the observation of the processing process, and preventing the harmful gas from emitting outward.

[0040] In some embodiments, a guide surface 7 and a guide groove 8 are provided at the bottom of the air outlet groove 5, and the guide surface 7 and the guide groove 8 are provided on a supporting platform 9. The guide surface is used to guide the liquid to the guide groove 8. The guide surface is arranged in an inclined shape, and the guide groove 8 is equivalent to being inclined in the vertical direction. The upper end of the guide groove 8 is connected to the guide surface 7, and the lower end of the guide groove 8 is connected to the liquid collecting device.

[0041] On the one hand, the guide surface 7 can buffer the compressed gas moving downward and prevent the compressed gas from reflecting outward, and on the other hand, it can collect and guide the liquid flowing down along the wind screen to ensure the flushing effect.

[0042] In some embodiments, the air outlet slot 5 is in a square hollow shape or a circular ring shape. This embodiment adopts a square hollow shape. The compressed gas in the air outlet slot 5 is ejected downward through a plurality of air outlet holes 510. When it is a square hollow shape, the air outlet holes 510 can also be set as a long and thin slit connected in sequence on four sides. Since the air outlet holes 510 are densely arranged on the same straight line of the four sides, the compressed gas ejected downward approximately forms a hollow invisible barrier. When the cutting fluid splashes, the splashed droplets will not splash out of the wind screen when they contact the wind screen, but will flow down in the direction of the compressed gas and gather in the guide groove of the processing platform. Such a design avoids the defects of the water baffle used in traditional machine tools. It not only plays a splash-proof role, but also the processing process is visible. When shielding is not needed, it can be closed. It has stable functions and convenient operation.

[0043] In some embodiments, the machine tool is equipped with a guide device, and the movable processing head is installed on the guide device; the guide device includes a transverse guide rail 2, a first slider, a second slider and a vertical guide rail, the first slider is installed on the transverse guide rail, the vertical guide rail is fixed to the first slider, the second slider is installed on the vertical guide rail, and the spindle box is installed on the second slider. There are multiple movable processing heads, and the multiple movable processing heads are installed together on the same transverse guide rail 2; there are multiple bearing platforms on the workbench, and the multiple bearing platforms correspond to the spindles of the multiple movable processing heads one by one; the liquid collection device is arranged at the bottom of the workbench, and the guide grooves of the multiple bearing platforms are connected to the liquid collection device.

[0044] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
