Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, and particularly to a rough machining and grinding equipment for brake disc production. Background Technique

[0002] The brake disc is an important component when the vehicle brakes. The braking performance of the vehicle directly affects the driving safety of the vehicle. The brake disc is essentially a disc-shaped object with a circular shape. When the vehicle is running, the brake disc rotates with the vehicle's transmission shaft. When the vehicle brakes, the brake caliper clamps both sides of the brake disc through the brake pads to generate braking force, thereby decelerating or stopping the vehicle. Currently, brake discs are usually manufactured by casting to obtain an integral structure.

[0003] Due to the casting process, the working surfaces on both sides of the brake disc are relatively rough. After production, rough machining is required to remove the redundant and rough materials on both sides of the brake disc. Currently, the rough machining of brake discs is mostly carried out by grinding. For example, the utility model patent with the publication number CN219234760U discloses a grinding machine for rough machining of brake discs. In the above solution, the brake disc contacts the grinding device and rotates to achieve the grinding of the brake disc. However, only one brake disc can be processed at a time, and only one side of the grinding device contacts the brake disc, and the other side cannot be ground, reducing the grinding efficiency.

[0031] Referring to Figures 1-7 , a rough machining and grinding device for brake disc production, comprising: a base 1, a grinding mechanism and a jig mechanism. The grinding mechanism is arranged on the upper side of the base 1, and the jig mechanism is arranged above the front side of the base 1. The grinding mechanism includes two first grinding discs 2, a plurality of second grinding discs 3 and a sliding component. The two first grinding discs 2 are symmetrically arranged, and the mutually facing surfaces are grinding surfaces. The plurality of second grinding discs 3 are all located between the two first grinding discs 2, and both sides are grinding surfaces. The two first grinding discs 2 and the plurality of second grinding discs 3 are all vertically arranged, and the bottoms are all rotatably connected to the sliding component. The sliding component includes two first screw rods 4 and multiple sets of clamping components. The multiple sets of clamping components respectively correspond to the two first grinding discs 2 and the plurality of second grinding discs 3. The clamping component includes a slider 5, a clamping block 6 and a ring body 7. The clamping block 6 is fixedly installed on the upper side of the slider 5. The ring body 7 is fixedly sleeved on the outer side of the first grinding disc 2 and is slidably embedded in the clamping block 6. The two first screw rods 4 are both horizontally rotatably sleeved in the base 1 and are both threadedly sleeved with the multiple sliders 5. A driving component is arranged at the end of the base 1 to drive the first screw rod 4 to rotate. The first screw rod 4 is provided with multiple sections of threads, and the pitch of the threads gradually increases from the middle to both sides. A transmission component is arranged in the middle of the base 1, and the multiple ring bodies 7 are driven to rotate by the transmission component. A cleaning mechanism is arranged at the rear side of the base 1 for cleaning metal chips. The total number of the two first grinding discs 2 and the plurality of second grinding discs 3 is an even number, so that it can be ensured that the brake disc in the middlemost part does not need to move.

[0032] The driving component includes a first motor 8, a machine shell 9, two driven wheels 10, a driving wheel 11, an auxiliary wheel 12 and a transmission belt 13. The machine shell 9 is fixedly installed at the side end of the base 1. The ends of the two first screw rods 4 both penetrate into the machine shell 9. The two driven wheels 10 are respectively fixedly sleeved on the ends of the two first screw rods 4. The first motor 8 is fixedly installed on the outer side of the machine shell 9, and the output end penetrates into the machine shell 9. The driving wheel 11 is fixedly sleeved on the output end of the first motor 8. The auxiliary wheel 12 is rotatably installed in the machine shell 9. The two driven wheels 10, the driving wheel 11 and the auxiliary wheel 12 are connected by the transmission belt 13.

[0033] The transmission components include a second motor 14, a transmission shaft 15, multiple pairs of collar rings 16, multiple gears 17, and multiple toothed rings 18. The second motor 14 is fixedly installed at the end of the base 1. Multiple pairs of collar rings 16 are respectively rotatably sleeved in multiple clamping blocks 6 and are symmetrically arranged. The transmission shaft 15 is horizontally rotatably sleeved in the base 1, and its end is fixedly connected to the output end of the second motor 14 through a coupling. The collar rings 16 are slidably sleeved on the transmission shaft 15. Multiple toothed rings 18 are respectively fixedly sleeved on the outer arc surfaces of multiple ring bodies 7. Multiple gears 17 are all slidably sleeved on the transmission shaft 15 and are respectively located in multiple clamping blocks 6 and are meshed and connected with the corresponding toothed rings 18.

[0034] Both ends of the transmission shaft 15 are cylindrical, and the middle part protrudes symmetrically. The collar rings 16, the gears 17 and the transmission shaft 15 are slidably sleeved with each other. Due to the protruding structure, when the transmission shaft 15 rotates, the collar rings 16 and the gears 17 rotate synchronously to achieve torque transmission.

[0035] The jig mechanism includes two support rods 19, a cross bar 20, a flipping component, and multiple groups of fixture components. Two support rods 19 are symmetrically and vertically fixedly installed at the front end of the base 1. The cross bar 20 is horizontally arranged, and its two ends are respectively fixedly installed at the tops of the two support rods 19. The flipping component is arranged on the cross bar 20. Multiple groups of fixture components are divided into two groups and are symmetrically arranged at the center on the flipping component.

[0036] The flipping component includes two sliding plates 21, four sliding rods 22, and four handles 23. The upper and lower sides of the cross bar 20 are flat, and the front and rear sides are arc-shaped. A sliding opening 24 is formed in the middle of each of the two sliding plates 21. The middle part of the sliding opening 24 is a circular hole, and the diameter of the circular hole is the same as the arc diameter of the cross bar 20. The sliding plates 21 are slidably sleeved on the cross bar 20 through the sliding openings 24. The four sliding rods 22 are divided into two groups and are symmetrically and horizontally fixedly installed on both sides of the two sliding plates 21. The four handles 23 are respectively fixedly installed at the ends of the two sliding plates 21 and are symmetrically arranged at the center. Each group of fixture components is arranged on two sliding rods 22 of the same group.

[0037] The fixture assembly includes two support blocks 25, an insertion block 26, two push blocks 27, two screw sleeves 28, a second screw 29, a worm 30 and a worm gear 31. The two support blocks 25 in the middlemost set of fixture assemblies are respectively fixedly sleeved on two slide rods 22, and the two support blocks 25 in the remaining fixture assemblies are respectively slidably sleeved on two slide rods 22. The insertion block 26 is fixedly installed at the tops of the two support blocks 25. The two push blocks 27 are symmetrically and slidably installed in the insertion block 26, and multiple push rods 271 are horizontally fixedly installed at their outer ends. The push rods 271 penetrate through the side walls of the insertion block 26. The two screw sleeves 28 are respectively fixedly sleeved on the sides of the two push blocks 27 close to each other. The second screw 29 is horizontally rotatably sleeved in the middle of the insertion block 26, and its two ends are respectively threadedly sleeved in the two screw sleeves 28. The worm gear 31 is fixedly sleeved in the middle of the worm 30. The worm 30 is vertically rotatably sleeved in the middle of the insertion block 26, and its end is meshed and connected with the worm gear 31. Springs 32 are sleeved between two adjacent support blocks 25 on the same slide rod 22, and the two ends of the springs 32 are respectively fixedly connected to the sides of the two support blocks 25 close to each other.

[0038] When using this device to perform rough machining and grinding operations on brake discs, first place multiple brake discs vertically on multiple sets of fixture assemblies respectively, so that the bottoms of the brake discs are clamped into the insertion block 26. Then rotate the worm 30. The worm 30 drives the worm gear 31 to rotate. The worm gear 31 drives the second screw 29 to rotate. The second screw 29 makes the two screw sleeves 28 move away from each other, so that the two push blocks 27 move away from each other. Multiple push rods 271 respectively clamp the inner walls of the brake discs, realizing the fixation of the brake discs.

[0039] After the brake disc is combined and fixed with the insertion block 26, pull the two slide plates 21 to move through the two handles 23, so that the cross bar 20 is combined with the circular hole in the middle of the sliding opening 24, and then turn it upwards, so that the fixed brake disc is turned to the lower side. Then push the jig mechanism, so that multiple brake discs move between the two first grinding discs 2 and multiple second grinding discs 3. Then start the first motor 8. The driving wheel 11 drives the two driven wheels 10 to rotate through the transmission belt 13. The two first screws 4 rotate driven by the driven wheels 10, so that multiple sliders 5 move. The sliders 5 drive the clamping blocks 6 to move. The clamping blocks 6 drive the first grinding discs 2 and the second grinding discs 3 to move and converge towards the middle, pushing multiple brake discs to converge towards the middle, and at the same time compressing the springs 32.

[0040] Finally, the inner sides of the two first grinding discs 2 and the two sides of the multiple second grinding discs 3 respectively contact the two sides of the multiple brake discs. Then the second motor 14 rotates, drives the transmission shaft 15 to rotate through the coupling. The transmission shaft 15 drives multiple gears 17 to rotate. The gears 17 drive the toothed ring 18 to drive the ring body 7 to rotate. The ring body 7 drives the corresponding first grinding discs 2 and second grinding discs 3 to rotate, realizing the rough machining and grinding operations on the brake discs.

[0041] In the above manner, the two first grinding discs 2 and the multiple second grinding discs 3 clamp the multiple brake discs, and the rough machining and grinding operations are carried out synchronously, enabling the two sides of the multiple second grinding discs 3 to work simultaneously, and the two sides of the multiple brake discs to be ground simultaneously, thereby improving the efficiency of the rough machining operation.

[0042] After a set of brake discs complete the grinding operation, the first motor 8 starts to rotate in the reverse direction, causing the two first screw rods 4 to rotate in reverse, driving the multiple sliders 5 to disperse to both sides, thereby releasing the clamping force on the ground brake discs. At the same time, the spring 32 resumes its original state, and the multiple brake discs separate. Then, the flipping component is pulled again to exchange the positions of the ground brake discs and the brake discs to be ground, entering the next grinding cycle.

[0043] With the cooperation of the fixture mechanism, while a set of brake discs is being ground, the fixture assembly on the other side can be operated to unload the brake discs that have just completed the grinding operation, and then the brake discs to be ground can be loaded into the fixture assembly again to wait for grinding. Thus, during grinding, loading and unloading can be carried out, shortening the operation cycle and further improving the efficiency of the rough machining operation.

[0044] The cleaning mechanism includes a pipeline component, a suction device 33, a pump body device 34, and two solenoid valves 35. The suction device 33 and the pump body device 34 are both fixedly installed on the upper side of the base 1, and the two solenoid valves 35 are respectively fixedly installed at the output end of the pump body device 34 and the input end of the suction device 33.

[0045] The pipeline component includes multiple sealing rings 36, multiple hoses 37, a horizontal pipe 38, and two frames 39. Cavities 40 are respectively formed inside the first grinding discs 2 and the second grinding discs 3. The multiple sealing rings 36 are respectively hermetically and rotatably embedded in the multiple cavities 40. Multiple air holes 41 are formed on the side where the two first grinding discs 2 are close to each other and on both sides of the multiple second grinding discs 3. The multiple air holes 41 are all communicated with the cavities 40. The horizontal pipe 38 is horizontally fixedly installed on the upper side of the base 1 through the two frames 39. Both ends of the multiple hoses 37 are fixedly connected and communicated with the multiple sealing rings 36 and the horizontal pipe 38 respectively. The end of the hose 37 close to the sealing ring 36 is fixedly connected to the corresponding clamping block 6 through a connecting frame 42. The output end of the pump body device 34 and the input end of the suction device 33 are respectively fixedly connected and communicated with both ends of the horizontal pipe 38.

[0046] During the grinding process, the suction device 33, the pump body device 34, and the two solenoid valves 35 operate alternately to clean the metal chips ground off. After the brake disc contacts the first grinding disc 2 and the second grinding disc 3, the pump body device 34 operates and the corresponding solenoid valve 35 is turned on, the suction device 33 is turned off and the corresponding solenoid valve 35 is cut off. The pump body device 34 sends the coolant into multiple hoses 37 through the horizontal pipe 38. The coolant enters multiple cavities 40 through the multiple hoses 37 respectively and finally discharges from the air holes 41 to cool the brake disc. Then grinding is carried out. Then, the pump body device 34 stops and the corresponding solenoid valve 35 is cut off, the suction device 33 starts and the corresponding solenoid valve 35 is turned on for suction. The metal chips ground off enter the cavity 40 through the air holes 41, then enter the hose 37 from the cavity 40, then enter the horizontal pipe 38, and finally the suction device 33 sucks and discharges the metal chips, thus realizing the timely cleaning of the metal chips and preventing them from affecting the grinding operation.

[0047] When the pump body device 34 operates, it can cool the brake disc and at the same time dredge the pipeline components to ensure the smoothness of the suction operation.

[0048] Each electrical device is powered by an external power supply, and the entire device is controlled by a control terminal. Since the control terminal is a common device and belongs to the existing mature technology, the electrical connection relationship and the specific circuit structure are not described in detail here.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
