[0017] The present invention has the following beneficial effects: 1. The processing device and processing method for mechanical parts, the design of the conversion device can adjust whether the grinding wheel needs to grind the workpiece. Under the drive of the No. 2 driving gear, the grinding wheel is driven to rotate around the welding head. At this time, due to the design of the high and low track grooves and the track slide bar, the telescopic outer cylinder and its internal components and the grinding wheel at the bottom of the telescopic outer cylinder will slide upward by an end distance as a whole. At this time, the grinding wheel cannot contact the surface of the workpiece, and the welding process can be carried out. Through this design, the purpose of the device itself is effectively changed, so that the device can switch between welding and pretreatment processes, avoiding the situation where the pretreatment process is still working while welding. The No. 1 driving gear meshing with the No. 2 driving gear and the No. 1 driving gear fixedly connected to the No. 1 driving gear can be driven by the drive motor. The rotating ring above the driving gear rotates around the welding head, and is driven by the driving motor to drive the rotating ring to continuously swing left and right within a certain range. Through this swing, the grinding wheel at the bottom of the rotating ring can be further driven to swing and grind the surface of the workpiece. While the telescopic outer cylinder rotates with the rotating ring around the welding head, due to the design of the No. 1 fixed tooth block and the No. 2 fixed tooth block on the side wall of the telescopic outer cylinder, the telescopic outer cylinder itself rotates around the welding head while the telescopic outer cylinder rotates around the welding head. The grinding wheel is eccentrically installed at the bottom of the telescopic outer cylinder. Therefore, while the grinding wheel is rotating and grinding with the welding head as the axis, it itself is also rotating eccentrically. Through this design, the grinding range of the grinding wheel can be further expanded, thereby improving the grinding efficiency.

[0018] 2. The processing device and processing method for mechanical parts, through the design of the spraying device, during the process of rotating and grinding the telescopic outer cylinder, through the design of the spiral groove and the spiral slider in the telescopic outer cylinder, the telescopic outer cylinder is driven to slide up and down during the self-rotation of the telescopic outer cylinder, and the bottom of the spraying piston plate is in contact with the inner wall of the telescopic outer cylinder. Therefore, through the lifting and lowering movement of the spraying piston plate, the cutting fluid in the bottom of the telescopic outer cylinder can be squeezed, and then the cutting fluid is driven to spray out through the spraying pipe, so that the cutting fluid covers the surface of the workpiece and the surface of the grinding wheel. The cutting fluid plays a vital role in metal cutting, mainly including cooling effect: the cutting fluid can take away the heat generated in the cutting process, reduce the temperature of the tool and the workpiece, and prevent overheating and deformation. Lubrication effect: the cutting fluid can reduce the friction between the tool and the workpiece, reduce the cutting force, and improve the processing efficiency and surface quality. Cleaning effect: the cutting fluid can clean the chips and impurities generated in the cutting process and keep the cutting area clean. Anti-rust effect: certain components in the cutting fluid can prevent the tool and the workpiece from rusting during the processing. By spraying this cutting fluid, the problem of poor grinding effect on the grinding wheel surface due to long-term work can be greatly reduced.

[0019] 3. The processing device and processing method for mechanical accessories, when the No. 2 driving gear drives the telescopic outer cylinder to slide to the other side of the welding head, the telescopic outer cylinder will slide upward a distance, and the welding process can be started at this time. The telescopic outer cylinder is driven by the No. 2 driving gear to slide at a higher position, and the cleaning component can be driven to clean the debris remaining on the surface of the workpiece. During the sliding process of the telescopic outer cylinder, the telescopic outer cylinder contacts the contact plate, and the contact plate is driven to slide upward with the No. 2 tooth plate fixedly connected thereto, and the cleaning annular extrusion plate is driven to slide downward in the cleaning ring groove through the transmission gear shaft and the No. 1 tooth plate, so that the cleaning annular extrusion plate squeezes the gas in the cleaning ring groove and discharges it through the pneumatic cleaning hole. Through this design, the debris remaining on the surface of the workpiece can be effectively cleaned, thereby ensuring the normal progress of the welding process. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] Example 1: This example aims to solve the problem that the existing pre-processing equipment requires the use of additional equipment, and it takes time to move the workpiece from one equipment to another, which affects the processing efficiency. Please refer to Figures 1 to 9 A processing device for mechanical parts includes a welding device 1, the welding device 1 includes a mounting plate 11, a welding head 12 is installed at the bottom of the mounting plate 11, a through-wire hole 13 is arranged in the welding head 12, and a pre-processing device 2 is arranged on the side wall of the welding head 12.

[0032] The pre-processing device 2 includes a grinding wheel 28 disposed on one side of the bottom of the welding head 12 . The grinding wheel 28 is mounted on the bottom of a rotating ring 23 . The rotating ring 23 is disposed on the bottom of the mounting plate 11 .

[0033] Before the welding process begins, the workpiece needs to be pretreated. A common pretreatment device usually grinds the welding surface of the workpiece through a grinding wheel 28. Grinding can remove surface defects generated during the welding process, improve the appearance quality of the weld, make it smoother and brighter, meet the design requirements, prepare for subsequent painting or anti-corrosion treatment, and ensure that the coating can firmly adhere to the weld surface.

[0034] The outer wall of the welding head 12 is provided with a mounting ring groove 21, and a mounting block 22 is slidably connected in the mounting ring groove 21. A rotating ring 23 is fixedly connected to the outer side of the mounting block 22, and a No. 1 driving gear 24 is fixedly connected to the top of the rotating ring 23. The No. 1 driving gear 24 is arranged around the outer wall of the welding head 12, and the No. 1 driving gear 24 is meshingly connected to the No. 2 driving gear 25. A driving motor 26 is fixedly connected to the top of the No. 2 driving gear 25, and the driving motor 26 is installed at the bottom of the mounting plate 11. A separating protective ring 29 is fixedly connected to the bottom of the rotating ring 23.

[0035] A rotary grinding device 3 is provided at the bottom of the rotating ring 23, and the rotary grinding device 3 includes a telescopic piston rod 31 fixedly connected to the bottom of the rotating ring 23, and the outer wall of the telescopic piston rod 31 is slidably connected to a telescopic outer cylinder 32, and the outer wall of the telescopic outer cylinder 32 is fixedly connected to a No. 1 fixed tooth block 33, and the No. 1 fixed tooth block 33 is meshingly connected to a No. 2 fixed tooth block 34, and the No. 2 fixed tooth block 34 is fixedly connected to the inner wall of the bottom ring 35, and the bottom ring 35 is fixedly connected to the bottom of the mounting plate 11, and a grinding motor 27 is eccentrically installed at the bottom of the telescopic outer cylinder 32.

[0036] The driving motor 26 drives the No. 1 driving gear 24 meshing with the No. 2 driving gear 25 and the rotating ring 23 fixedly connected to the No. 1 driving gear 24 to rotate around the welding head 12. The driving motor 26 drives the rotating ring 23 to continuously swing left and right within a certain range. Through this swing, the grinding wheel 28 at the bottom of the rotating ring 23 can be further driven to swing and grind the surface of the workpiece. While the telescopic outer cylinder 32 rotates around the welding head 12 with the rotating ring 23, Due to the design of the No. 1 fixed tooth block 33 and the No. 2 fixed tooth block 34 on the side wall of the telescopic outer cylinder 32, while the telescopic outer cylinder 32 rotates around the welding head 12, the telescopic outer cylinder 32 itself also rotates with the telescopic piston rod 31 as the axis, and the grinding wheel 28 is eccentrically installed at the bottom of the telescopic outer cylinder 32. Therefore, while the grinding wheel 28 rotates and grinds with the welding head 12 as the axis, it also rotates eccentrically. Through this design, the grinding range of the grinding wheel 28 can be further expanded, thereby improving the grinding efficiency.

[0037] A conversion device 4 is provided in the bottom ring 35, and the conversion device 4 includes a high and low track groove 41 opened on the inner wall of the bottom ring 35, and the high and low track groove 41 is located above the No. 2 fixed gear block 34. A track slide bar 42 is slidably connected in the high and low track groove 41, and a rotating block 43 is fixedly connected to the other end of the track slide bar 42. The rotating block 43 is slidably connected in the rotating ring groove 44, and the rotating ring groove 44 is opened on the outer wall of the telescopic outer cylinder 32.

[0038] The design of the conversion device 4 can adjust whether the grinding wheel 28 needs to grind the workpiece. Under the drive of the second driving gear 25, the grinding wheel 28 is driven to rotate around the welding head 12. At this time, due to the design of the high and low track grooves 41 and the track slide bar 42 (refer to Figure 8 The design of the middle and low trajectory groove 41 makes the telescopic outer cylinder 32 and its internal components and the grinding wheel 28 at the bottom of the telescopic outer cylinder 32 slide upward by an end distance as a whole. At this time, the grinding wheel 28 cannot contact the surface of the workpiece, and the welding process can be carried out. Through this design, the purpose of the device itself is effectively changed, so that the device can switch between welding and pretreatment processes, avoiding the situation where the pretreatment process is still working while welding.

[0039] Embodiment 2: This embodiment is intended to promote the solution of the problem that the grinding wheel 28 generates heat during the grinding process, resulting in poor grinding effect. This embodiment is an explanation based on the embodiment 1. For details, please refer to Figures 1 to 9 A spraying device 5 is arranged in the telescopic outer cylinder 32, and the spraying device 5 includes a spraying chute 51 opened in the telescopic piston rod 31, a spraying piston plate 52 is slidably connected in the spraying chute 51, a spraying spring 53 is fixedly connected to the top of the spraying piston plate 52, the other end of the spraying spring 53 is fixedly connected in the spraying chute 51, and the bottom of the spraying piston plate 52 is slidably connected in the telescopic outer cylinder 32.

[0040] A spiral slider 510 is fixedly connected to the side wall of the spray piston plate 52 . The spiral slider 510 is slidably connected in a spiral groove 59 . The spiral groove 59 is provided on the inner wall of the telescopic outer cylinder 32 .

[0041] During the process of rotating and grinding the telescopic outer cylinder 32, the design of the spiral groove 59 and the spiral slider 510 in the telescopic outer cylinder 32 drives the spray piston plate 52 in the telescopic outer cylinder 32 to slide up and down during the self-rotation of the telescopic outer cylinder 32, and the bottom of the spray piston plate 52 fits the inner wall of the telescopic outer cylinder 32. Therefore, the cutting fluid in the bottom of the telescopic outer cylinder 32 can be squeezed by the lifting movement of the spray piston plate 52, and then the cutting fluid is driven to spray out through the spray pipe 54, so that the cutting fluid covers the surface of the workpiece and the surface of the grinding wheel 28. The cutting fluid plays a vital role in metal cutting, mainly including cooling effect: the cutting fluid can take away the heat generated in the cutting process, reduce the temperature of the tool and the workpiece, and prevent overheating and deformation. Lubrication effect: the cutting fluid can reduce the friction between the tool and the workpiece, reduce the cutting force, and improve the processing efficiency and surface quality. Cleaning effect: the cutting fluid can clean the chips and impurities generated in the cutting process and keep the cutting area clean. Anti-rust effect: certain components in the cutting fluid can prevent the tool and the workpiece from rusting during the processing. By spraying the cutting fluid, the problem of poor grinding effect on the surface of the grinding wheel 28 due to long-term work can be reduced to a great extent.

[0042] A connecting channel 58 is provided at the bottom of the spray piston plate 52 and the telescopic piston rod 31, and a No. 1 hose 55 is connected to the top of one of the connecting channels 58. The other end of the No. 1 hose 55 is connected to the No. 2 hose 56 through the connecting channel 58 in the telescopic piston rod 31, and the other end of the No. 2 hose 56 is connected to the No. 3 hose 57. The outlet of the other end of the No. 3 hose 57 is arranged on the outside of the bottom ring 35, and a spray pipe 54 is fixedly connected to the bottom of the telescopic outer cylinder 32.

[0043] The connection between hose No. 1 55, hose No. 2 56, hose No. 3 57 and connecting channel 58 continuously replenishes the cutting fluid for the space formed by the telescopic outer cylinder 32, thereby ensuring the normal supply of the cutting fluid. At the same time, a one-way valve (not marked) can be arranged in the above-mentioned channel and in the spraying pipe 54. Through the design of the one-way valve, each rise of the spraying piston plate 52 can replenish the cutting fluid into the space, thereby realizing the function of automatic fluid supply.

[0044] Example 3: This example is intended to help solve the problem of debris remaining on the workpiece surface after grinding. This example is an explanation based on Example 2. For details, please refer to Figures 1 to 9 A cleaning assembly 6 is arranged in the separation protection ring 29, and the cleaning assembly 6 includes a cleaning ring groove 61 opened in the separation protection ring 29, a cleaning annular extrusion plate 62 is slidably connected in the cleaning ring groove 61, and a pneumatic cleaning hole 63 is connected to the bottom of the cleaning ring groove 61. The pneumatic cleaning hole 63 is opened at the bottom of the separation protection ring 29, and the pneumatic cleaning hole 63 is arranged circumferentially.

[0045] A movable groove 69 is opened in the separation protection ring 29, and a No. 1 tooth plate 64 and a No. 2 tooth plate 65 are slidably connected in the movable groove 69. The No. 1 tooth plate 64 is fixedly connected to the top of the cleaning annular extrusion plate 62, and the No. 1 tooth plate 64 is meshingly connected with a transmission gear shaft 66, and the transmission gear shaft 66 is rotatably connected in the separation protection ring 29. The transmission gear shaft 66 is meshingly connected with the No. 2 tooth plate 65, and a return spring 67 is fixedly connected to the top of the No. 2 tooth plate 65, and the other end of the return spring 67 is fixedly connected in the movable groove 69. One end of the No. 2 tooth plate 65 is fixedly connected to a contact plate 68, and the contact plate 68 is contacted by the telescopic outer cylinder 32.

[0046] When the No. 2 driving gear 25 drives the telescopic outer cylinder 32 to slide to the other side of the welding head 12, under the design of the high and low track grooves 41 and the track slide bar 42, the telescopic outer cylinder 32 will slide upward a distance, and the welding process can be started at this time. The telescopic outer cylinder 32 is driven by the No. 2 driving gear 25 to slide at a higher position, and the cleaning component 6 can be driven to clean the debris remaining on the surface of the workpiece. During the sliding process of the telescopic outer cylinder 32, the telescopic outer cylinder 32 contacts the contact plate 68, driving the contact plate 68 to slide upward with the No. 2 tooth plate 65 fixedly connected thereto, and through the transmission of the transmission gear shaft 66 and the No. 1 tooth plate 64, the cleaning annular extrusion plate 62 is driven to slide downward in the cleaning annular groove 61, so that the cleaning annular extrusion plate 62 squeezes the gas in the cleaning annular groove 61 and discharges it through the pneumatic cleaning hole 63. Through this design, the debris remaining on the surface of the workpiece can be effectively cleaned, thereby ensuring the normal progress of the welding process. The design of the first tooth plate 64, the second tooth plate 65 and the transmission gear shaft 66 can change the distance that the cleaning annular extrusion plate 62 can descend by designing the transmission ratio among the three, so as to improve the exhaust effect of the pneumatic cleaning hole 63 and further improve the cleaning effect.

[0047] This embodiment also discloses a method for using a processing device for mechanical parts, comprising the following steps: S1. Select appropriate welding materials and welding processes, prepare necessary welding tools such as solder wire and soldering iron, and ensure the integrity and applicability of these equipment. At the same time, check whether the soldering iron head is clean and can be stained with solder; S2. Thoroughly clean the welding area to ensure that there is no oil, rust or other impurities. This helps to ensure the quality of welding and avoid undesirable phenomena during welding; S3. Preheat the welding workpiece to reduce welding stress and deformation and improve welding quality; S4. According to the welding materials and process requirements, formulate process parameters such as welding current, voltage, welding speed, and carry out necessary welding tests and process evaluations to ensure the smooth progress of the welding process.
