Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a grinder for sheet metal welding parts. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching, cutting, compounding, folding, welding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. In the production and processing of sheet metal parts, sheet metal parts need to be welded to obtain sheet metal welded parts. Since welds will remain on the outer wall of the welded parts during welding, in order not to affect the subsequent processing of the welded parts, the outer wall welds of the sheet metal welded parts need to be polished.

[0003] The Chinese patent publication number CN216327186U discloses a grinder for high-strength sheet metal welded parts. The device can prevent strong light from causing eye discomfort to the viewing staff during the grinding process through a sunshade. The progress of the grinding process can be viewed in real time. The waste generated by spark cooling in the grinding process will fall into the material trough. By removing the movable plate on the rear side of the material trough, the waste chips inside the material box can be quickly cleared. There is no need to set up unnecessary driving mechanisms such as screws, which greatly reduces the cost of the overall device.

[0004] However, during the grinding process, the friction between the grinding disc and the workpiece will cause the grinding disc and the workpiece to heat up. When grinding for a long time, this high temperature may cause the thermal stress of the workpiece to increase, and then cause the workpiece to deform or crack. This will not only affect the quality of the workpiece, but may also cause the workpiece to be scrapped and increase production costs.

[0005] Therefore, a grinding machine for sheet metal welded parts is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] like Figure 1-4 As shown, the present application provides a grinding machine for sheet metal welded parts, comprising: a processing table 1, a support frame 104 is fixedly mounted on the top surface of the processing table 1, a support plate 101 is fixedly mounted on the bottom surface of the processing table 1, a moving device 103 is movably mounted on the bottom surface of the support frame 104, and fixing devices 102 are fixedly mounted on the inner walls of both sides of the support frame 104;

[0031] A grinding mechanism 2 is provided below the support frame 104 and includes a grinding disc 206 located below the moving device 103. A motor 204 is provided above the grinding disc 206 for grinding sheet metal weldments.

[0032] Specifically, such as Figure 1-2 As shown, an electric push rod 201 is fixedly installed on the bottom surface of the moving device 103, a concave plate 202 is fixedly installed on the lower end of the electric push rod 201, a moving plate 203 is fixedly installed on the bottom surface of the concave plate 202, and the inner wall of the upper end of the concave plate 202 is fixedly connected to the upper end of the motor 204.

[0034] Specifically, such as Figure 1-2 As shown, a rotating shaft 205 is fixedly installed at the output end of the motor 204. The lower end of the rotating shaft 205 rotates through the first bearing seat and passes through the top surface of the movable plate 203 to extend to the bottom of the movable plate 203. The lower end of the rotating shaft 205 is fixedly connected to the top surface of the grinding disc 206.

[0035] In this embodiment, the motor 204 is turned on to drive the rotating shaft 205 to rotate. When the rotating shaft 205 rotates, the grinding disc 206 is driven to rotate, thereby grinding the sheet metal weldment.

[0036] The cooling mechanism 3 is arranged on one side of the grinding mechanism 2. The cooling mechanism 3 includes a storage tank 312 fixedly mounted on the top surface of the support frame 104. A nozzle 310 is provided below the support frame 104 for cooling the grinding disc 206 and the sheet metal welded parts.

A bevel gear 2 302 is fixedly installed on the outer wall of the left end of the connecting shaft 303, and the outer wall of the bevel gear 2 302 is internally meshed with the outer wall of the bevel gear 1 301.

[0038] In this embodiment, the rotating shaft 205 drives the bevel gear 1 301 to rotate, which drives the bevel gear 2 302 and the connecting shaft 303 to rotate, thereby driving subsequent transmission.

[0039] Specifically, such as Figure 1-4 As shown, a turntable 304 is fixedly installed at the other end of the connecting shaft 303, a connecting rod 305 is hinged on the side edge of the turntable 304, a movable rod 308 is hinged on the other end of the connecting rod 305, a fixed box 306 is fixedly installed on the top surface of the movable plate 203, the other end of the movable rod 308 is movable through the side of the fixed box 306 and extends to the inside of the fixed box 306, a piston plate 307 is slidably installed on the inner wall of the fixed box 306, and the side of the piston plate 307 is fixedly connected to one end of the movable rod 308.

[0040] In this embodiment, the rotating disk 304 is rotated by the connecting shaft 303, the rotating disk 304 drives the connecting rod 305 to move, the connecting rod 305 drives the movable rod 308 to move back and forth, and the movable rod 308 drives the piston plate 307 to move back and forth on the inner wall of the fixed box 306.

[0041] Specifically, such as Figure 1-4 As shown, a one-way valve 311 is fixedly installed on the top surface of the fixed box 306, and a hose 313 is fixedly installed on the upper end of the one-way valve 311. The other end of the hose 313 slides through the bottom surface of the support frame 104 and the bottom surface of the storage tank 312 and extends to the inside of the storage tank 312.

[0042] In this embodiment, by setting the one-way valve 311, the fixed box 306 can only absorb the coolant from the hose 313 and the storage tank 312 through the one-way valve 311, and the coolant in the fixed box 306 will not flow back into the hose 313.

[0043] Specifically, such as Figure 1-4As shown, a water outlet pipe 309 is fixedly installed on the upper end of the nozzle 310, and the upper end of the water outlet pipe 309 is fixedly passed through the bottom surface of the movable plate 203 and the bottom surface of the fixed box 306 and extends to the inside of the fixed box 306.

By adjusting the electric push rod 201, the grinding disc 206 is controlled to grind the sheet metal welded parts, ensuring that the sheet metal welded parts can be fully polished, which is more convenient. At the same time, the shaft 205 drives the bevel gear 1 301 to rotate, drives the bevel gear 2 302 and the connecting shaft 303 to rotate, and the connecting shaft 303 drives the rotating shaft 205. The disk 304 rotates, and the turntable 304 drives the connecting rod 305 and the movable rod 308 to move. The movable rod 308 drives the piston plate 307 to move back and forth. When the piston plate 307 moves forward, the coolant is sucked from the storage tank 312 into the fixed box 306 through the one-way valve 1 311 and the hose 313. Then, when the piston plate 307 moves backward, the coolant is pushed through the one-way valve 2 314 and the outlet pipe 309 from the nozzle 310 to the sheet metal welded parts and the grinding disk 206, so as to cool the sheet metal welded parts and ensure that the sheet metal welded parts are not easily deformed or cracked due to excessive temperature during long-term grinding, thereby improving the quality of the sheet metal welded parts and reducing production costs.
