[0032] Embodiment 1

[0033] Reference Figure 1-Figure 4 The present invention discloses a multi-station brake disc grinding equipment, including: a double-station structure 100, including a first station platform 101 and a second station platform 102, the first station platform 101 and the second station platform 102 move alternately between a loading and unloading location 103 and a grinding location 104; a grinding structure 200 installed at the grinding location 104; a multi-station clamping structure 300 is provided on both the first station platform 101 and the second station platform 102, the multi-station clamping structure 300 includes a driven gear 301, a rack 302 is fixed at the grinding location 104, when the driven gear 301 passes through the rack 302 and enters the grinding location 104, the multi-station clamping structure 300 realizes the clamping of the brake disc.

[0034] By adopting the above structure, by controlling the first work station 101 and the second work station 102 to move back and forth alternately between the loading and unloading place 103 and the grinding place 104, the brake disc on the second work station 102 can be loaded and unloaded when the brake disc on the first work station 101 is being ground, and the brake disc is ground by using a double work station, which effectively improves the grinding efficiency of the brake disc; by further arranging a multi-station clamping structure 300 on the first work station 101 and the second work station 102, multiple brake discs can be installed on one work station at the same time, so as to realize the simultaneous grinding of multiple brake discs on the first work station 101 or the second work station 10, and further improve the grinding efficiency of the brake disc;

[0035] In addition, the multi-station clamping structure 300 controls the rotation of the driven gear 301 to clamp or release the brake disc, and the rack 302 is set. Before the multi-station clamping structure 300 moves to the bottom of the grinding structure 200 for grinding, the driven gear 301 will pass through the rack 302, so that under the restriction of the rack 302, the driven gear 301 rotates, and the multiple brake discs on the first station 101 or the second station 10 are clamped and fixed through the clamping structure. Then, after the grinding is completed, the driven gear 301 moves away from the bottom of the grinding structure 200, and the rack 302 rotates. Under the restriction, the driven gear 301 rotates in the opposite direction to the previous direction, and the multiple brake discs on the first work station 101 or the second work station 10 are unclamped through the clamping structure, so that the brake discs can be clamped or unclamped during the alternating movement of the first work station 101 and the second work station 102. When arriving at the loading and unloading point 103, the loading and unloading device (not shown in the figure, it can be an existing loading and unloading device such as a robot) can directly put in or remove the multiple brake discs on the first work station 101 or the second work station 10, effectively improving the loading and unloading efficiency and reducing labor costs or equipment costs.

[0036] The structure for controlling the first work station 101 and the second work station 102 to alternately move back and forth between the loading and unloading area 103 and the grinding area 104 is shown in FIG. Figure 2-Figure 3 In detail, in this embodiment, the double-station structure 100 also includes a supporting substrate 105, and slide rails 106 are symmetrically fixed on both sides of the top of the supporting substrate 105. The two slide rails 106 are provided with guide grooves 110 on the sides away from each other. A slide seat 107 is slidably connected to the slide rail 106, and a guide rail 108 perpendicular to the length direction of the slide rail 106 is opened on the slide seat 107. The first station 101 is slidably connected to the guide rail 108 on one side, and the second station 102 is slidably connected to the guide rail 108 on the other side. One end of the first station 101 and the second station 102 is provided with a roller 109 slidably connected to the inside of the guide groove 110;

[0037] Through grooves 111 are symmetrically provided on both sides of the top of the supporting base plate 105, a first pulley 112 and a second pulley 113 are fixed at both ends of the bottom of the supporting base plate 105, a driving motor 114 is fixedly installed on one side of the top of the supporting base, the output end of the driving motor 114 is fixedly connected to the first pulley 112, the first pulley 112 and the second pulley 113 are connected by a belt 115, the entire belt 115 includes parts located on both sides of the first pulley 112 and the second pulley 113, one side slide 107 is fixedly connected to one side of the belt 115 by a belt clamp 116, and the other side slide 107 is fixedly connected to the other side of the belt 115 by a belt clamp 116.

[0038] One end of the belt clamp 116 is fixedly clamped on the belt 115, and the other end is fixedly connected to the slide 107. As the belt 115 moves, the slide 107 is driven to move through the belt clamp 116. The movement directions of the two side parts of the entire belt 115 are opposite. Therefore, when the belt 115 rotates, when the slide 107 on one side drives the first workstation 101 to move forward, the slide 107 on the other side will drive the second workstation 102 to move backward. The drive motor 114 adopts a servo motor. In this way, the drive motor 114 is intermittently controlled to rotate forward and reverse, so as to drive the first workstation 101 and the second workstation 102 to move back and forth alternately between the loading and unloading area 103 and the grinding area 104 through the first pulley 112, the second pulley 113 and the belt 115. Among them, the setting of the guide groove 110, during the movement of the slide 107, is restricted by the roller 606 on the guide rail 108, and the first work station 101 and the second work station 102 will move along the path of the guide groove 605 when passing through the path of the guide groove 605. When the first work station 101 and the second work station 102 move to the two ends of the supporting substrate 105, they will be located at the same loading and unloading place 103 and grinding place 104, so as to facilitate the loading and unloading device and the grinding structure 200 to load and unload and grind the brake disc on the first work station 101 or the second work station 102.

[0039] Reference Figure 1 and Figure 5 In detail, in the present embodiment, the grinding structure 200 includes a fixed frame 201, a telescopic cylinder 202 fixed on the fixed frame 201, the telescopic cylinder 202 can be a pneumatic telescopic cylinder or a hydraulic telescopic cylinder, a grinding box 203 is fixed at the output end of the telescopic cylinder 202, and the top of the grinding box 203 is fixed to a first guide column 204 that passes through the fixed frame 201; the multi-station clamping structure 300 adopts a four-station clamping structure, a grinding motor 205 is fixed at the top of the grinding box 203, and the bottom of the grinding box 203 is provided with grinding blocks 206 corresponding to the four stations in the four-station clamping structure.

[0040] Under the restriction of the first guide column 204, the telescopic cylinder 202 can stably drive the grinding box 203 to move up and down stably when telescoping; thereby driving the grinding motor 205 and the grinding block 206 to move synchronously. The number of grinding blocks 206 corresponds to the clamping position of each brake disc, and multiple brake discs can be polished at the same time. The grinding motor 205 provides power for the grinding block 206 to grind.

[0041] Reference Figure 3In detail, in this embodiment, the rack 302 is fixed on the supporting substrate 105, the guide groove 110 includes two first horizontal grooves 110a, two oblique grooves 110b and a second horizontal groove 110c, one first horizontal groove 110a is connected to one end of the second horizontal groove 110c through an oblique groove 110b, and the other first horizontal groove 110a is connected to the other end of the second horizontal groove 110c through another oblique groove 110b. The second horizontal groove 110c is close to the grinding structure 200, and the driven gear 301 moves along the direction of the second horizontal groove 110c through the same rack 302, and the multi-station clamping structure 300 realizes the clamping of the brake disc.

[0042] The guide grooves 110 on both sides of the support substrate 105 are arranged so that when the first station 101 or the second station 102 moves to a first horizontal groove 110a, it will move to the grinding position along the first horizontal groove 110a. At the same time, when the second station 102 or the first station 101 moves to another first horizontal groove 110a, it will move to the loading and unloading position 103 along the first horizontal groove 110a. The arrangement of the inclined grooves 110b on both sides makes the first station 101 and the second station 10 When passing through the inclined groove 110b and moving to the second horizontal groove 110c in the middle, the first work station 101 and the second work station 102 will not interfere with each other; and when the first work station 101 or the second work station 102 moves to the grinding position along the first horizontal groove 110a, it will pass through the rack 302, so that the driven gear 301 at the bottom of the first work station 101 or the second work station 102 rotates when passing through the rack 302, so as to clamp or release the brake disc.

[0043] Embodiment 2

[0044] Reference Figure 6-Figure 8In this embodiment, in order to realize the clamping, fixing or unclamping of multiple brake discs on the first workstation 101 and the second workstation 102 at the same time, based on the same concept as the above-mentioned embodiment 1, the multi-station brake disc grinding equipment is on the first workstation 101, and the multi-station clamping structure 300 includes four clamping control shafts 303 rotatably connected to the first workstation 101, and the top of the clamping control shaft 303 is fixed with a support clamp seat 304, and the top of the clamping control shaft 303 is fixed with a shaft cylinder 305 sleeved on the outside of the clamping control shaft 303, and the outside of the shaft cylinder 305 is fixed with a plurality of second guide columns 306, and the support clamp seat 304 is provided with a plurality of guide grooves 307 corresponding to the second guide columns 306, and the inside of the guide groove 307 is penetrated by a movable column 308, and the bottom end of the movable column 308 is fixed with a sliding The guide block 309 is sleeved on the outside of the second guide column 306, and the top of the movable column 308 is connected with a clamping block 310. It should be noted that in order to ensure the clamping effect of the clamping block 310 on the brake disc, when fixing brake discs of different specifications, the clamping block 310 on the top of the movable column 308 is an adjustable structure (such as a bolt adjustment structure, which is not shown in the figure); when the clamping control shaft 303 is controlled to rotate, under the action of the guide groove 307, the movable column 308 will be driven to move along the trajectory of the guide groove 307, so that the guide block 309 at the bottom end of the movable column 308 is limited by the second guide column 306 and will move along the length direction of the second guide column 306, thereby driving the multiple clamping blocks 310 to approach or move away from each other, so as to clamp or release the side of the brake disc;

[0045] The center of the bottom of the first work station 101 is fixedly connected to a support shaft seat 311, and the outer side of the support shaft seat 311 is rotatably connected to a control gear 312. A clamping control shaft 303 passes through the bottom of the first work station 101 and is fixedly sleeved with a control pinion 313 meshing with the outer side of the control gear 312. The bottom end of one of the clamping control shafts 303 is fixedly sleeved with a driven gear 301 coaxially arranged with the control pinion 313. When the first work station 101 or the second work station 102 moves to the grinding position 104, the driven gear 301 will be affected during the movement. The rack 302 is restricted to rotate, and through the rotation of the driven gear 301, the driven gear 301 will synchronously drive a coaxially arranged control pinion 313 to rotate. The rotation of one control pinion 313 will drive the other control pinions 313 to rotate through the control gear 312, thereby realizing the synchronous action of the four clamping structures on the first workstation 101 to clamp the four brake discs on the first workstation 101. It should be noted that the above embodiment is not limited to four, and less than four or more than four can be set according to actual needs.

[0046] Among them, the multi-station clamping structure 300 on the second workstation 102 has the same structure and principle as the multi-station clamping structure 300 on the first workstation 101, and will not be elaborated here. The difference is that the multi-station clamping structure 300 on the second workstation 102 and the multi-station clamping structure 300 on the first workstation 101 are symmetrically arranged on both sides of the supporting substrate 105. Among them, the driven gears 301 under the first work station 101 and the second work station 102 are symmetrically arranged on both sides of the supporting substrate 105, and the side of the rack 302 with teeth is located on the side of the extension line between the loading and unloading area 103 and the grinding area 104, so that the driven gears 301 under the first work station 101 and the second work station 102 will engage with the rack 302 when moving to the grinding area 104. Since the driven gears 301 under the first work station 101 and the second work station 102 are symmetrically arranged, when passing through the same rack 302, the rotation directions of the two driven gears 301 are the same.

[0047] Embodiment 3

[0048] Reference Fig. 9 In this embodiment, in order to realize that one motor drives multiple (such as four) grinding blocks 206 corresponding to the grinding stations on the first workstation 101 or the second workstation 102 to move simultaneously to grind the brake disc below, based on the same concept as the above-mentioned embodiment 1, this multi-station brake disc grinding equipment also includes a grinding box 203 that is internally rotatably connected with a driving shaft 203a and four driven shafts 203b, the external fixed sleeve of the driving shaft 203a is provided with a driving large gear 203c, and the external fixed sleeve of the driven shaft 203b is provided with a driven small gear 203d, and the four driven small gears 203d are respectively meshed with the outer periphery of the driving large gear 203c, and the top of the driving large gear 203c is connected to the output end of the grinding motor 205, and each grinding block 206 is correspondingly fixedly connected to the outside of one end of each driven shaft 203b that passes through the bottom of the grinding box 203. When the grinding motor 205 is working, its output end will drive the driving large gear 203c to rotate, and the driving large gear 203c will simultaneously drive the four driven small gears 203d on the periphery to rotate, thereby driving the four grinding blocks 206 to move simultaneously.

[0049] Working principle:

[0050] In the initial position, no brake disc is placed on the first work station 101 and the second work station 102, wherein the first work station 101 is located at the loading and unloading place 103, and the second work station 102 is located at the grinding place 104. At this time, the clamping blocks 310 on the four work stations on the first work station 101 are all in a state of being away from each other, while the clamping blocks 310 on the four work stations on the second work station 102 are all in a state of being close to each other;

[0051] During operation, the loading and unloading device places the brake disc to be polished directly on each station on the first station 101, and then starts the driving motor 114 to rotate forward, so that the first station 101 is located at the polishing position 104, and the second station 102 is located at the loading and unloading position 103. When the first station 101 moves to the polishing position 104, it will pass through the rack 302. Under the restriction of the rack 302, the driven gear 301 under the first station 101 rotates, thereby synchronously driving the clamping structure of each station on the first station 101 to move by controlling the large gear 312 and the small gear 313. Specifically, when the control small gear 313 drives the clamping control shaft 303 to rotate, under the action of the guide groove 307, The movable column 308 is driven to move along the track of the guide groove 307, so that the guide block 309 at the bottom end of the movable column 308 is limited by the second guide column 306 and moves along the length direction of the second guide column 306, thereby driving the multiple clamping blocks 310 to approach each other to clamp and fix the side of the brake disc, and then the grinding motor 205 and the telescopic cylinder 202 are started, and the telescopic cylinder 202 drives the grinding block 206 to fit with the upper surface of the brake disc, and the grinding motor 205 drives the large gear 203c and the driven small gear 203d to simultaneously drive the four driven small gears 203d on the periphery to rotate, thereby driving the four grinding blocks 206 to move at the same time, so as to realize the grinding of the brake disc of each station on the first station platform 101;

[0052] Since the second work station 102 is located at the loading and unloading place 103 at this time, during the grinding of the brake disc on the first work station 101, the loading and unloading device directly places the brake disc to be ground on each work station of the second work station 102; after the grinding of the brake disc on the first work station 101 is completed, the driving motor 114 is controlled to reverse, and the second work station 102 drives the upper brake disc to move to the grinding place 104. When passing through the rack 302, it will be placed in the same way as the first work station 101. The brake disc is clamped and fixed, and then the grinding structure 200 grinds the brake disc of each station on the second station 102; at the same time, when the first station 101 is away from the grinding place 104, it will return along the trajectory of the rack 302, and will drive the clamping structure of each station on the first station 101 to release the brake disc, so that when the first station 101 moves to the loading and unloading place 103, the loading and unloading device can directly remove the brake disc on the first station 101. Then, the driving motor 114 is repeatedly controlled to rotate forward and reverse, so as to realize the alternate clamping, grinding and loading and unloading of multiple brake discs on the first station 101 and the second station 102.

[0053] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
