Description

Technical Field

[0001] This application relates to the technical field of circular ring grinding, and particularly to a surface grinding device for circular ring castings. Background Art

[0002] The processes for casting circular ring castings mainly include sand casting, precision casting, die casting, etc. Sand casting is more common in large-scale production due to its advantages of low cost and simple process; precision casting can manufacture castings with high precision and complex shapes; die casting is suitable for producing thin-walled and complex-structured castings. However, limited by the characteristics of these casting processes themselves, the surface roughness of the produced circular ring castings often cannot directly meet the technical standards required for actual applications. This requires professional technicians to use external equipment, such as a grinding machine, to grind and process the castings to improve their surface quality.

[0003] In the current grinding operation process of circular ring castings, generally, a feeding device, such as a robotic arm with a relatively high degree of automation, is first used to accurately place the circular ring casting on the working table of the grinding machine. Subsequently, through a specially designed fixture, the inner wall of the circular ring casting is firmly fixed to ensure that the casting does not displace during the grinding process. At this time, the grinding head of the grinding machine contacts the outer surface of the circular ring casting and grinds the outer surface of the casting according to the set parameters and paths.

[0004] After the outer surface grinding process is completed, it is also necessary to manually release the fixture, and then readjust and fix the outer wall of the circular ring casting before the inner surface grinding work of the circular ring casting can be carried out. The operation steps are relatively cumbersome, consuming a large amount of time and labor costs, and the inner and outer walls of the circular ring casting need to be ground in a fixed grinding sequence (i.e., the sequence of grinding the outer wall first and then the inner wall), thus reducing the grinding efficiency of the circular ring casting.

Detailed implementation manners

[0019] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0020] The surface grinding equipment for ring castings according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0021] As Figures 1-9 shown, the surface grinding equipment for ring castings according to the embodiments of the present application includes a support frame 10, a grinding device 20, a cam disc 30, a first driving component 40, a second driving component 50, and an arc-shaped baffle 60.

[0022] Among them, a partition board 11 is provided in the middle of the support frame 10, and the grinding device 20 may include a cylinder body 21, a disc 22, a first grinding component 23, a plurality of limit components 24, a gear ring 25, and a plurality of second grinding components 26.

[0023] Among them, the disc 22 is rotatably arranged on the partition plate 11, and the disc 22 is fixedly connected to one end face of the cylinder body 21 through a bracket. A plurality of material taking ports 201 are formed in the cylinder body 21. For example, the plurality of material taking ports 201 can be 4, 5, 6, 7, 8, 9, 10 material taking ports 201, etc. The specific number used can be selected according to the actual situation (for example, 4 material taking ports 201, etc.), which is not limited herein. Among them, the plurality of material taking ports 201 are arranged in a circumferential array for grasping the ring-shaped castings to be polished.

[0024] In the embodiment of the present application, an inclined loading rack is arranged on one side of the support frame 10, and the bottom end of the loading rack is close to the cylinder body 21. Among them, the loading rack is used for placing the ring-shaped castings to be polished.

[0025] The first polishing assembly 23 is rotatably arranged in the cylinder body 21. A plurality of limiting assemblies 24 are arranged around the first polishing assembly 23 in the cylinder body 21, and the plurality of limiting assemblies 24 are respectively arranged close to the corresponding material taking ports 201. Among them, the first polishing assembly 23 is used for polishing the outer surface of the ring-shaped castings.

[0026] The gear ring 25 is fixedly arranged on the support frame 10, and the gear ring 25 is respectively connected to the plurality of limiting assemblies 24. A plurality of second polishing assemblies 26 are respectively slidably arranged on the disc 22, and the plurality of second polishing assemblies 26 are respectively arranged in one-to-one correspondence with the plurality of material taking ports 201. Among them, the second polishing assembly 26 is used for polishing the inner surface of the ring-shaped castings.

[0027] The cam disc 30 is fixedly arranged on the support frame 10. The cam disc 30 is respectively slidably connected to the plurality of second polishing assemblies 26. The first driving assembly 40 is arranged on the support frame 10, and the first driving assembly 40 is respectively intermittently connected to the plurality of second polishing assemblies 26. Among them, the first driving assembly 40 is used to provide a rotating force for the plurality of second polishing assemblies 26.

[0028] In the embodiment of the present application, a limiting slideway 31 is formed in the cam disc 30. The limiting slideway 31 may include a first arc slideway 311 and a second arc slideway 312. Among them, the first arc slideway 311 and the second arc slideway 312 enclose a closed-loop slideway, and the height of the first arc slideway 311 is higher than that of the second arc slideway 312, and the radius of the first arc slideway 311 is smaller than that of the second arc slideway 312. It should be particularly noted that the position of the first arc slideway 311 described in this embodiment corresponds to the position of the arc-shaped baffle 60.

[0029] It can be understood that the cam disc 30 controls the radial displacement of the second polishing assembly 26 through the arc slideways with different heights.

[0030] The second driving component 50 is arranged on the partition plate 11, and the second driving component 50 is connected to the disc 22. Among them, the second driving component 50 is used to drive the disc 22 to rotate. The arc-shaped baffle 60 is fixedly arranged on the support frame 10, and the arc-shaped baffle 60 semi-surrounds the cylinder body 21. Among them, the arc-shaped baffle 60 is used to limit the circular ring casting on the limiting component 24, and at the same time, the arc-shaped baffle 60 can also block the splashing of grinding debris and protect the safety of the operator.

[0031] Specifically, when it is necessary to grind the inner and outer surfaces of the circular ring casting simultaneously, the relevant staff first need to place a large number of circular ring castings to be ground side by side on the loading rack (not shown in the figure), and then control the second driving component 50 to drive the disc 22 to drive the cylinder body 21, the first grinding component 23, multiple limiting components 24 and multiple second grinding components 26 to rotate. When the material taking port 201 on the cylinder body 21 is opposite to the circular ring casting to be ground placed on the loading rack, the circular ring casting to be ground rolls through the material taking port 201 into the corresponding limiting component 24. As the cylinder body 21 drives the taken circular ring casting to be ground to rotate, when passing through the arc-shaped baffle 60, the arc-shaped baffle 60 exerts a pressure on the circular ring casting to be ground to move towards the limiting component 24. The pressed limiting component 24 spreads towards both sides, and makes the outer surface of the circular ring casting to be ground contact with the first grinding component 23. At the same time, since the limiting component 24 is connected to the gear ring 25, when the limiting component 24 makes a circular motion, the limiting component 24 drives the circular ring casting to be ground to rotate.

[0032] Subsequently, the staff control the first grinding component 23 to grind the outer surface of the circular ring casting during the rotation process. When the second grinding component 26 rotates to the first arc-shaped slideway 311 of the cam disc 30, the second grinding component 26 extends into the circular ring casting and contacts the inner surface of the circular ring casting and the first driving component. At this time, the staff control the first driving component 40 to drive the second grinding component 26 to grind the inner surface of the circular ring casting. Thus, the inner and outer surfaces of the circular ring casting can be ground simultaneously, effectively improving the grinding efficiency of the circular ring casting and ensuring the consistency of product quality.

[0033] When the ground circular ring casting breaks away from the limit of the arc-shaped baffle 60, the ground circular ring casting is pushed out from the material taking port 201 under the reaction force of the limiting component 24, thereby completing the automatic unloading of the ground circular ring casting, avoiding the time waste and operation error caused by manual frequent disassembly of the fixture, and effectively improving the loading and unloading efficiency.

[0034] For the sake of clearly explaining the previous embodiment, in an embodiment of the present application, such as Figures 2-3 and Figure 5 、 Figure 8As shown, the first grinding assembly 23 may include a grinding wheel 231 and a first driving mechanism 232. Among them, the grinding wheel 231 is rotatably arranged in the cylinder body 21.

[0035] The first driving mechanism 232 is arranged on the end face at the other end of the cylinder body 21, and the output end of the first driving mechanism 232 penetrates into the cylinder body 21 and is connected to the rotating shaft of the grinding wheel 231.

[0036] It should be noted that the first driving mechanism 232 described in this embodiment may be a driving motor.

[0037] It can be understood that the staff can control the first driving mechanism 232 to drive the grinding wheel 231 to rotate so as to grind the outer surface of the circular ring casting.

[0038] Furthermore, in an embodiment of the present application, as Figures 6-9 shown, the limiting assembly 24 may include two support cylinders 241, a driving shaft 242, a transmission gear 243, and two limiting mechanisms 244.

[0039] Among them, the two support cylinders 241 are symmetrically distributed and are respectively fixedly arranged on the inner walls at both ends of the cylinder body 21, and the two support cylinders 241 are located below the middle of the material taking port 201.

[0040] The driving shaft 242 is rotatably arranged on the end wall at the other end of the cylinder body 21, and one end of the driving shaft 242 penetrates the end wall of the cylinder body 21 and extends into the corresponding support cylinder 241. The other end of the driving shaft 242 is fixedly connected to the transmission gear 243. Among them, the transmission gear 243 meshes with the toothed ring 25.

[0041] The two limiting mechanisms 244 are symmetrically distributed on both sides of the corresponding material taking port 201, and each limiting mechanism 244 is respectively rotatably connected to the two support cylinders 241.

[0042] The limiting mechanism 244 may include two driving arms 2441, a support shaft 2442, a first support plate 2443, a plurality of driving wheels 2444, a second support plate 2445, a plurality of first springs 2446, and a first belt transmission mechanism 2447.

[0043] Among them, one ends of the two driving arms 2441 are respectively rotatably sleeved on the corresponding support cylinders 241, and both ends of the support shaft 2442 are respectively rotatably connected to the other ends of the two driving arms 2441. The first support plate 2443 is fixedly arranged between the two driving arms 2441, and a plurality of driving wheels 2444 are equidistantly arranged side by side on the support shaft 2442. For example, the plurality of driving wheels 2444 may be 3, 4, 5, 6, 7, 8 driving wheels 2444, etc. The specific number used can be selected according to the actual situation (for example, 4 driving wheels 2444, etc.), and is not limited here.

[0044] The second support plate 2445 is fixedly arranged in the cylinder body 21 close to the first support plate 2443, and a plurality of first springs 2446 are arranged equidistantly and side by side between the first support plate 2443 and the second support plate 2445. For example, the plurality of first springs 2446 can be 2, 3, 4, 5 first springs 2446, etc. The specific number used can be selected according to the actual situation (for example, two first springs 2446, etc.), and no limitation is made here.

[0045] The first belt transmission mechanism 2447 is respectively connected to the support shaft 2442 and the drive shaft 242.

[0046] It should be noted that the first belt transmission mechanism 2447 described in this embodiment may include a first driving pulley, a first driven pulley and a first belt. Among them, the first driving pulley is sleeved and fixed on the drive shaft 242, the first driven pulley is sleeved and fixed on the support shaft 2442, and the first belt is sleeved on the first driving pulley and the first driven pulley.

[0047] It can be understood that when the to-be-polished ring-shaped casting enters the cylinder body 21 through the material taking port 201, the to-be-polished ring-shaped casting is located between the two limiting mechanisms 244 and respectively abuts against the driving wheels 2444 in the two limiting mechanisms 244.

[0048] When the to-be-polished ring-shaped casting rotates with the cylinder body 21 to below the arc-shaped baffle 60, the arc-shaped baffle 60 applies a thrust force to the to-be-polished ring-shaped casting towards the two limiting mechanisms 244. At this time, the two stressed limiting mechanisms 244 expand outwards, that is, the driving wheels 2444 in the limiting mechanism 244 push the two driving arms 244 to rotate around the support cylinder 241 as the rotation axis through the support shaft 24421. At this time, the two rotating driving arms 244 compress the first springs 2446 through the first support plate 2443. At the same time, the reverse force generated by the first springs 2446 acts on the outer surface of the to-be-polished ring-shaped casting through the driving wheels 2444, so as to form a force that hugs the to-be-polished ring-shaped casting. At the same time, the outer surface of the to-be-polished ring-shaped casting moving towards the middle of the two limiting mechanisms 244 contacts the grinding wheel 231, and the outer surface of the ring-shaped casting is ground by controlling the rotation of the grinding wheel 231.

[0049] When the limiting component 24 rotates with the cylinder body 21, since the transmission gear 243 in the limiting component 24 meshes with the gear ring 25, the transmission gear 243 is driven and drives the drive shaft 242 to rotate. The rotating drive shaft 242 drives the support shaft 2442 to rotate through the first belt transmission mechanism 2447. The rotating support shaft 2442 drives a plurality of driving wheels 2444 to drive the to-be-polished ring-shaped casting to rotate by relying on friction, so that the grinding wheel 231 can evenly grind the outer periphery of the outer surface of the ring-shaped casting.

[0050] When the polished ring-shaped casting disengages from the limit of the arc-shaped baffle 60, the drive wheels 2444 in the two limit mechanisms 244 are reset under the reverse action of the first spring 2446, and apply a thrust towards the outside of the cylinder body 21 to the polished ring-shaped casting, and push the polished ring-shaped casting out of the material taking port 201 to complete discharging.

[0051] Further, in an embodiment of the present application, as Figure 2 , Figure 3 , Figures 5-9 shown, the second polishing assembly 26 may include a first slider 261, a second spring 262, a spline sleeve 263, a driven gear 264, a spline shaft 265, a polishing roller 266 and a second slider 267.

[0052] Among them, a plurality of through grooves 221 are formed in the disk 22, and the plurality of through grooves 221 are respectively distributed in one-to-one correspondence with the plurality of material taking ports 201. The first slider 261 is slidably arranged in the corresponding through groove 221. It should be particularly noted that the through groove 221 described in this embodiment has a limiting function and can prevent the first slider 261 from sliding out of the through groove 221.

[0053] The second spring 262 is arranged in the through groove 221, and one end of the second spring 262 is fixedly connected to the first slider 261, and the other end of the second spring 262 is fixedly connected to the end face of the through groove 221.

[0054] The spline sleeve 263 is rotatably arranged on the first slider 261, and the spline sleeve 263 penetrates through the first slider 261. The driven gear 264 is sleeved and fixed on the spline sleeve 263. One end of the spline shaft 265 penetrates through the spline sleeve 263 and is fixedly connected to the polishing roller 266, and the other end of the spline shaft 265 is rotatably connected to the second slider 267. It should be particularly noted that the spline shaft 265 and the spline sleeve 263 described in this embodiment are meshed with each other, and the spline shaft 265 can move in the spline sleeve 263. The second slider 267 is slidably arranged in the limit slideway 31. It should be noted that the limit slideway 31 described in this embodiment is a closed-loop slideway and has a limiting function, and can effectively prevent the second slider 267 from sliding out of the limit slideway 31.

[0055] Further, in an embodiment of the present application, as Figure 8 shown, the first driving assembly 40 may include a second driving mechanism 41 and a driving gear 42. Among them, one end of the second driving mechanism 41 passes through the cam disk 30 and is fixedly connected to the support frame 10, the other end of the second driving mechanism 41 is fixedly connected to the driving gear 42, and the driving gear 42 is intermittently meshed with the driven gear 264.

[0056] It should be noted that the second driving mechanism 41 described in this embodiment may be a driving motor.

[0057] Specifically, when the disk 22 drives a plurality of second grinding assemblies 26 to rotate, when the second slider 267 in the second grinding assembly 26 moves from the second arc-shaped slideway 312 in the limit slideway 31 towards the first arc-shaped slideway 311, during this process, the second slider 267 drives the grinding roller 266 to extend into the interior of the to-be-ground circular ring casting through the spline shaft 265. When the second slider 267 slides into the first arc-shaped slideway 311, the second slider 267 pushes the first slider 261 to slide in the through groove 221 through the spline shaft 265 and compresses the second spring 262. At this time, the spline shaft 265 drives the grinding roller 266 to contact the inner surface of the to-be-ground circular ring casting, and at the same time, the spline shaft 265 drives the driven gear 264 to mesh with the driving gear 42.

[0058] Subsequently, the staff can control the second driving mechanism 41 to drive the driving gear 42 to drive the driven gear 264 to rotate. The rotating driven gear 264 drives the spline shaft 265 to rotate through the spline sleeve 263, and further drives the grinding roller 266 to rotate to grind the inner surface of the to-be-ground circular ring casting.

[0059] When the second slider 267 moves from the first arc-shaped slideway 311 in the limit slideway 31 into the second arc-shaped slideway 312, the spline shaft 265 drives the grinding roller 266 to be withdrawn from the inner cavity of the to-be-ground circular ring casting. At the same time, the spline shaft 265 drives the driven gear 264 to disengage from the driving gear 42, thereby completing the grinding of the inner surface of the circular ring casting and facilitating the blanking of the circular ring casting after grinding.

[0060] Furthermore, in an embodiment of the present application, as Figure 4 shown, the second driving assembly 50 may include a third driving mechanism 51 and a second belt transmission mechanism 52. Among them, the third driving mechanism 51 is fixedly arranged on the partition plate 11, and the output end of the third driving mechanism 51 is connected to the disk 22 through the second belt transmission mechanism 52.

[0061] It should be noted that the third driving mechanism 51 described in this embodiment may be a driving motor, and the second belt transmission mechanism 52 may include a second driving pulley, a second driven pulley, and a second belt.
