Description

Technical Field

[0001] The utility model relates to the field of grinding equipment, and particularly relates to a grinding equipment for machining automobile parts. Background Art

[0002] During the machining of automobile parts, it is necessary to grind the cross-sections of some non-smooth and uneven metal parts after cutting.

[0003] In the prior art, most of them are to set a grinding machine and a fixture on the processing table. When in use, the fixture is first used to clamp both sides of the automobile part, and then the grinding machine is used to grind the automobile part (the grinding machine usually uses a grinding wheel for processing and grinding). However, when the automobile part is being ground, it is very easy to generate high temperature at the position where the grinding wheel contacts the part to be ground. For this reason, some manufacturers will spray coolant to the grinding position for dust reduction and temperature reduction. However, due to the high-speed rotation of the grinding wheel, the debris and impurities generated by grinding and the sprayed coolant will splash around, which is not only difficult to clean but also may accidentally injure the surrounding workers.

[0004] Therefore, it is very necessary to invent a grinding equipment for machining automobile parts. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a grinding equipment for machining automobile parts, including an annular workbench and a grinding assembly. The grinding assembly is located at the upper end of the annular workbench. A water tank base is installed at the bottom of the annular workbench. Clamping assemblies are symmetrically installed on both sides of the upper end of the annular workbench. The clamping assemblies are located on both sides of the front end of the grinding assembly. A protective cover is arranged outside the upper end of the annular workbench. A cleaning assembly is installed in the middle of the protective cover. A lifting assembly is installed on one side of the outer ends of the annular workbench and the protective cover.

[0007] The cleaning assembly includes a fixed support plate and a rotating motor installed in the middle of the fixed support plate. A driving shaft is installed at the output end of the rotating motor. A guide rod is installed at the upper end of the driving shaft.

[0008] Outer scrapers and inner scrapers are installed on both sides of the upper end of the guide rod. The inner scraper is located below the outer scraper. Cleaning brushes are installed on both the inner wall and the outer wall of the outer scraper.

[0009] Based on the above features: The lifting component can drive the protective cover to move up and down. When the grinding component grinds the automotive parts, coolant can be sprayed onto the grinding position, which can not only reduce the high temperature generated by grinding, but also reduce dust, and try to prevent the debris generated by grinding from floating in the air. Due to the shielding and protection of the protective cover, the debris will remain on the upper end of the annular workbench and will not fly outwards, while the coolant after dust reduction will fall into the inner part of the water tank base for collection, facilitating secondary utilization. When the automotive parts are being processed and ground, the rotating motor can drive the guide rod to rotate through the drive shaft. At this time, the guide rod can synchronously drive the outer scraper and the inner scraper to rotate. The outer scraper is attached to the outer wall of the protective cover, and the inner scraper is located on the inner wall of the protective cover. When the outer scraper and the inner scraper rotate, the outer wall and the inner wall of the protective cover can be cleaned by the cleaning brush.

[0010] Preferably, an annular insertion plate is fixedly installed around the upper end of the annular workbench, and a water filtering net is arranged on the upper surface of the annular workbench.

[0011] Based on the above features: When the protective cover is pressed on the annular workbench, the annular insertion plate can position the protective cover, and try to avoid gaps between the protective cover and the annular workbench. The arranged water filtering net can filter the falling coolant and debris impurities.

[0012] Preferably, the grinding component includes a bracket and a grinding motor installed in the middle of the bracket, and a grinding wheel is installed at the output end of the grinding motor.

[0013] Based on the above features: The bracket can support and fix the grinding motor. When the grinding motor is started, it can drive the grinding wheel to rotate to grind the automotive parts.

[0014] Preferably, a water pump is installed at the upper end of the bracket. The coolant discharge end of the water pump is provided with a water outlet pipe, and the other end of the water outlet pipe is installed with a bent pipe. The coolant discharge ports at both ends of the bent pipe are located on both sides of the upper end of the grinding wheel. The input end of the water pump is connected with a water inlet pipe, and the other end of the water inlet pipe is connected to the water tank base.

[0015] Based on the above features: When the water pump is started, the coolant inside the water tank base can be pumped through the water inlet pipe, and then sprayed out from both sides of the upper end of the grinding wheel through the water outlet pipe and the bent pipe, which is convenient for cooling and dust reduction of the grinding wheel and the grinding part of the automotive parts.

[0016] Preferably, an observation glass is provided on the surface of the protective cover, a through hole is provided in the middle of the upper end of the protective cover, and a positioning slot is provided on the lower surface of the protective cover.

[0017] Based on the above features: When the protective cover descends, it can be inserted into the annular insertion plate through the positioning slot, and during the grinding of the automotive parts, it can be observed from the outside of the protective cover through the observation glass.

[0018] Preferably, the fixed support plate is installed in a U-shaped structure, and the guide rod movably penetrates through the through hole.

[0019] Based on the above features: both sides of the upper end of the fixed support plate are fixedly connected to the inner wall of the top of the protective cover, which is convenient for the fixed support plate to support and fix the rotating motor.

[0020] Preferably, the lifting assembly includes a fixed straight plate and a limit sliding groove formed on the upper surface of the fixed straight plate. A lifting cylinder is installed at the lower end of one side of the fixed straight plate close to the limit sliding groove, and a fixing plate is installed at the upper end of the lifting cylinder.

[0021] Based on the above features: the lifting cylinder can drive the protective cover to lift and adjust through the fixing plate, and the limit sliding groove can limit the fixing plate to make the fixing plate and the protective cover move vertically.

[0022] The beneficial effects of the present utility model are as follows:

[0023] 1. The lifting cylinder can drive the protective cover to lift and adjust through the fixing plate. When the protective cover rises, the clamping assembly and the grinding assembly will be exposed at the outer end. When the protective cover descends, the positioning slot at the lower end of the protective cover will be inserted and positioned with the annular plug board, avoiding gaps between the protective cover and the annular workbench. At this time, personnel can observe through the observation glass outside the protective cover, and the protective cover will provide protection above the annular workbench to prevent grinding-generated debris, impurities, and coolant from splashing outwards.

[0024] 2. The grinding-generated debris, impurities, and coolant will be blocked by the protective cover and cannot splash outwards. Eventually, they will fall above the annular workbench. At this time, the provided water filtering net can filter the falling coolant and debris, and the coolant can fall into the inner part of the water tank base through the water filtering net for storage, facilitating secondary utilization.

[0025] 3. During the process of grinding and processing automotive parts, the rotating motor can drive the guide rod to rotate through the drive shaft. At this time, the guide rod can synchronously drive the outer scraper and the inner scraper to rotate. The outer scraper fits on the outer wall of the protective cover, and the inner scraper is located on the inner wall of the protective cover. When the outer scraper and the inner scraper rotate, the outer wall and the inner wall of the protective cover and the observation glass can be cleaned by the cleaning brush.

Specific embodiments

[0031] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0032] Referring to the attached Figures 1-4 , a grinding device for automotive part processing provided by the present utility model includes an annular workbench 1 and a grinding component 4. The grinding component 4 is located at the upper end of the annular workbench 1. A water tank base 2 is installed at the bottom of the annular workbench 1. Clamping components 3 are symmetrically installed on both sides of the upper end of the annular workbench 1 (the clamping component 3 in this application is pneumatic. Two vertical cylinders can drive the horizontal cylinder and the clamping plate to lift and adjust, and the horizontal cylinder can drive the clamping plate to translate towards each other, so as to clamp and fix both sides of the automotive part. The prior art will not be specifically described), the clamping components 3 are located on both sides of the front end of the grinding component 4. A protective cover 5 is arranged outside the upper end of the annular workbench 1. A cleaning component 6 is installed in the middle of the protective cover 5. A lifting component 7 is installed on one side of the outer ends of the annular workbench 1 and the protective cover 5;

[0033] The cleaning component 6 includes a fixed support plate 61 and a rotating motor 62 installed in the middle of the fixed support plate 61. The output end of the rotating motor 62 is installed with a drive shaft 63, and a guide rod 64 is installed at the upper end of the drive shaft 63;

[0034] Outer scrapers 641 and inner scrapers 642 are installed on both sides of the upper end of the guide rod 64. The inner scraper 642 is located below the outer scraper 641. Cleaning brushes 643 are installed on both the inner wall and the outer wall of the outer scraper 641.

[0035] The lifting assembly 7 can drive the protective cover 5 to move up and down. When the protective cover 5 rises, the clamping assembly 3 and the grinding assembly 4 will be exposed. At this time, the automotive part can be placed between the two clamping assemblies 3 for clamping and fixing, and the position to be ground is located below the grinding assembly 4. Then, the lifting assembly 7 can drive the protective cover 5 to descend, so that the protective cover 5 can provide protection above the annular workbench 1. When the grinding assembly 4 grinds the automotive part, coolant can be sprayed onto the position to be ground, which can not only reduce the high temperature generated by grinding, but also reduce dust, and try to avoid the debris generated by grinding floating in the air. Due to the shielding protection of the protective cover 5, the debris will remain on the upper end of the annular workbench 1 and will not splash outwards, and the coolant after dust reduction will fall into the inside of the water tank base 2 for collection, which is convenient for secondary utilization. When the automotive part is being processed and ground, the rotation motor 62 can drive the guide rod 64 to rotate through the drive shaft 63. At this time, the guide rod 64 can synchronously drive the outer scraper 641 and the inner scraper 642 to rotate. The outer scraper 641 is attached to the outer wall of the protective cover 5, and the inner scraper 642 is located on the inner wall of the protective cover 5 (there are gaps between the clamping assembly 3, the grinding assembly 4 and the protective cover 5, which is convenient for the inner scraper 642 to move through this gap). When the outer scraper 641 and the inner scraper 642 rotate, the outer wall and the inner wall of the protective cover 5 can be cleaned by the cleaning brush 643.

[0036] Preferably, an annular insertion plate 11 is fixedly installed on the outer periphery of the upper end of the annular workbench 1, and a water filter net 12 is arranged on the upper end surface of the annular workbench 1 (the water filter net 12 is made of stainless steel material, and the size of the gaps of the water filter net 12 can be set according to needs by itself, and no specific limitation is made in this application).

[0037] When the protective cover 5 is pressed on the annular workbench 1, the annular insertion plate 11 can position the protective cover 5 and try to avoid leaving a gap between the protective cover 5 and the annular workbench 1. The arranged water filter net 12 can filter the falling coolant and debris impurities. The coolant can pass through the water filter net 12 and fall into the inside of the water tank base 2 for storage, while the debris impurities remain above the annular workbench 1 and the water filter net 12 and wait for manual unified cleaning after the protective cover 5 is opened.

[0038] Preferably, the grinding assembly 4 includes a bracket 41 and a grinding motor 42 installed in the middle of the bracket 41, and a grinding wheel 43 is installed at the output end of the grinding motor 42.

[0039] The bracket 41 can support and fix the grinding motor 42. When the grinding motor 42 is started, it can drive the grinding wheel 43 to rotate to grind the automotive part.

[0040] Preferably, a water pump 411 is installed at the upper end of the bracket 41. The coolant discharge end of the water pump 411 is provided with a water outlet pipe 412. The other end of the water outlet pipe 412 is installed with an elbow pipe 413. The coolant discharge ports at both ends of the elbow pipe 413 are located on both sides of the upper end of the grinding wheel 43. The input end of the water pump 411 is connected with a water inlet pipe 414, and the other end of the water inlet pipe 414 is connected to the water tank base 2.

[0041] When the water pump 411 is started, the coolant inside the water tank base 2 can be extracted through the water inlet pipe 414, and then sprayed out from both sides of the upper end of the grinding wheel 43 through the water outlet pipe 412 and the elbow pipe 413, which is convenient for cooling and dust removal of the grinding wheel 43 and the grinding part of the automotive part.

[0042] Preferably, an observation glass 51 is provided on the surface of the protective cover 5. A through hole 52 is provided in the middle of the upper end of the protective cover 5. A positioning slot 53 is provided on the lower surface of the protective cover 5.

[0043] When the protective cover 5 descends, it can be inserted into the annular insertion plate 11 through the positioning slot 53. During the grinding process of the automotive part, it can be observed from the outside of the protective cover 5 through the observation glass 51. In order to prevent external dust and internal splashing debris from falling on the outer wall and inner wall of the observation glass 51 and affecting the observation effect, the cleaning assembly 6 can rotate to clean the outer wall and inner wall of the protective cover 5 and the observation glass 51.

[0044] Preferably, the fixed support plate 61 is installed in a U-shaped structure, and the guide rod 64 movably passes through the through hole 52.

[0045] Both sides of the upper end of the fixed support plate 61 are fixedly connected to the inner wall of the top end of the protective cover 5, which is convenient for the fixed support plate 61 to support and fix the rotary motor 62 (holes can be provided on the surface of the protective cover 5 for the wires to pass through. There is no chute in this application, and it can be set according to needs specifically). The upper end of the guide rod 64 passes through the through hole 52 and is located outside the top end of the protective cover 5, so that the outer scraper 641 is located outside and fits against the outer wall of the protective cover 5, while the lower end of the guide rod 64 does not pass through the through hole 52, so that the inner scrapers 642 on both sides of the lower end of the guide rod 64 are located inside the protective cover 5 and fit against its inner wall.

[0046] Preferably, the lifting assembly 7 includes a fixed straight plate 71 and a limit chute 72 provided on the upper surface of the fixed straight plate 71. A lifting cylinder 73 is installed at the lower side of the fixed straight plate 71 close to the limit chute 72, and a fixing plate 74 is installed at the upper end of the lifting cylinder 73.

[0047] One end of the fixing plate 74 away from the lifting cylinder 73 is connected to the upper end of the guide rod 64 (the guide rod 64 and the fixing plate 74 can be rotatably connected through a bearing or a shaft body, so that the two will not separate, and at the same time, the fixing plate 74 will not rotate when the guide rod 64 rotates). The lifting cylinder 73 can drive the protective cover 5 to lift and adjust through the fixing plate 74, and the limit sliding groove 72 can limit the fixing plate 74 to make the fixing plate 74 and the protective cover 5 move vertically.

[0048] The using process of the utility model is as follows: the lifting cylinder 73 can drive the protective cover 5 to rise through the fixing plate 74. At this time, the clamping assembly 3 and the grinding assembly 4 will be exposed. Then, the automotive part is placed between the two clamping assemblies 3 for clamping and fixing, and the position to be ground is located below the grinding wheel 43. Then, the lifting cylinder 73 can drive the protective cover 5 to descend through the fixing plate 74, so that the positioning slot 53 at the lower end of the protective cover 5 is inserted into the annular insertion plate 11 for positioning. Finally, when the grinding motor 42 is started, it can drive the grinding wheel 43 to rotate to grind the automotive part. During the grinding process, the water pump 411 can be started. At this time, the water pump 411 can extract the coolant inside the water tank base 2 through the water inlet pipe 414, and then spray it out from both sides of the upper end of the grinding wheel 43 through the water outlet pipe 412 and the elbow pipe 413. The generated debris and impurities and the coolant will be blocked by the protective cover 5 and cannot splash outwards, and finally will fall above the annular workbench 1. The arranged water filtering net 12 can filter the falling coolant and debris and impurities. The coolant can fall into the water tank base 2 through the water filtering net 12 for storage, while the debris and impurities are left above the annular workbench 1 and the water filtering net 12 and wait for manual cleaning after the protective cover 5 is opened. Personnel can observe through the observation glass 51 at the outer end of the protective cover 5. During the grinding process of the automotive part, the rotating motor 62 can drive the guide rod 64 to rotate through the drive shaft 63. At this time, the guide rod 64 can synchronously drive the outer scraper 641 and the inner scraper 642 to rotate to clean the outer wall and the inner wall of the protective cover 5 and the observation glass 51.

[0049] The above are only the preferred embodiments of the present utility model.
