[0018] The following will further elaborate on the present invention in conjunction with the embodiments given in the accompanying drawings.

[0019] Refer to Figure 1 — Figure 10 As shown in the figure, the brake disc frustum end face grinder of this embodiment includes a machine frame 1 and a grinding mechanism 2 arranged on the machine frame 1. The machine frame 1 is provided with a loading seat 3 and a driving mechanism 4. The driving mechanism 4 is connected to the loading seat 3 to drive the loading seat 3 to move. The loading seat 3 is provided with a loading mechanism 5, and the loading mechanism 5 includes: A rotating disk 51 rotatably arranged on the loading seat 3. The rotating disk 51 is located below the grinding mechanism 2, and a number of circumferentially distributed driving holes 511 are provided on the rotating disk 51; A connecting seat 52 fixedly arranged on the rotating disk 51. There are a number of the connecting seats 52, which are arranged in one-to-one correspondence with the driving holes 511. The driving holes 511 are located at the central position of the connecting seat 52; A processing table 53 rotatably arranged on the connecting seat 52. A driven block 531 is provided on the lower side of the processing table 53, and part of the driven block 531 passes through the driving hole 511 and is located below the rotating disk 51; A driving motor 54 fixed on the lower side of the loading seat 3 and located below the rotating disk 51. The position of the driving motor 54 matches the position of the loading mechanism 5. A driving block 541 is provided on the driving motor 54, and a driving groove 542 is provided on the driving block 541. The driven block 531 can be combined with / separated from the driving groove 542; A cleaning mechanism 6 is provided on the frame 1. The cleaning mechanism 6 is used to clean the debris ground by the grinding machine. A liftable partition plate 11 is provided on the frame 1. The partition plate 11 isolates the grinding mechanism 2 from the outside.

[0020] Through the above technical solution, when using this brake disc frustum end face grinding machine, first determine the size of the brake disc to be processed. After determination, the driving mechanism 4 operates to drive the loading seat 3 to move, change the position of the loading mechanism 5, and select the corresponding model of the processing table 53 according to the size of the brake disc, so that the brake disc on the connecting seat 52 can be comprehensively and stably ground during the rotation of the rotating disc 51.

[0021] During the operation of the equipment, when a processing table 53 is at the processing position below the grinding mechanism 2, the next processing table 53 is at the loading position. During the processing, the operator can complete the operations of taking materials, flipping / loading, reducing the waiting time, improving the production efficiency, and the loading position is far from the processing position, ensuring safety during the production process.

[0022] Then, when using the frustum end face grinding machine of this application to process the brake disc, the operator places the brake discs on the connecting seat 52 passing through the loading position in sequence. The rotating disc 51 rotates to drive the connecting seat 52 to move to the lower side of the grinding mechanism 2. The movement of the connecting seat 52 causes the processing table 53 on it to move. During the movement of the processing table 53 to the lower side of the grinding mechanism 2, the driven block 531 enters the driving groove 542 and combines with the driving groove 542. After combination, the driving block 541, the processing table 53, and the driven block 531 are coaxial; then the grinding mechanism 2 operates, that is, the grinding disc rotates and descends to grind the upper end face of the brake disc. During the grinding process, the driving motor 54 operates to drive the driving block 541 to rotate, and drives the processing table 53 to rotate through the driving groove 542 and the driven block 531, thereby driving the brake disc to rotate and completing the grinding of the upper side of the brake disc.

[0023] It should be noted that before the rotating disc 51 rotates, the partition plate 11 rises, and the lower end face of the partition plate 11 is higher than the upper end face of the brake disc on the processing table 53; when the brake disc stops rotating, the partition plate 11 descends to isolate the grinding mechanism 2 from the outside, avoiding the situation of flying debris during grinding.

[0024] And during the production and processing, the cleaning mechanism 6 operates to clean the ground debris, eliminating the need for manual cleaning during downtime, enabling the equipment to be used for a long time, and further improving the production efficiency.

[0025] As a specific implementation of the improvement, a guiding protrusion 31 is provided on the feeding base 3. A guiding groove 32 is provided in the guiding protrusion 31. The driven block 531 is located in the guiding groove 32. A receiving groove 33 is provided in the guiding groove 32. The position of the receiving groove 33 corresponds to the position of the driving motor 54. The guiding protrusion 31 is provided with a through hole at the bottom of the receiving groove 33. The driving block 541 is located in the receiving groove 33. The lower end of the driving block 541 passes through the through hole and is connected to the driving motor 54.

[0026] Through the above technical solution, during the rotation of the rotating disk 51, the driven block 531 moves in the guiding groove 32, so that when the processing table 53 moves to the position of the driving motor 54, the driven block 531 can smoothly engage with the driving groove 542, and then is driven by the driving motor 54 to rotate, thereby driving the processing table 53 to rotate, improving the stability during use; the driving block 541 is located in the receiving groove 33, so that the position of the driving block 541 is stable, thereby improving the stability during the rotation of the driven block 531 and the processing table 53.

[0027] Specifically, a bearing is provided in the receiving groove 33. The outer ring of the bearing is fixedly connected to the receiving groove 33, and the inner ring is fixedly connected to the driving block 541, further improving the stability of the driving block 541 during rotation.

[0028] Specifically, the driving groove 542 is opened at the upper end position of the driving block 541, the bearing is located at the lower side position of the driving block 541, and the driving groove 542 is misaligned.

[0029] As a specific implementation of the improvement, a limiting block 543 is provided on one side of the driving groove 542. When the driven block 531 engages with the driving groove 542, the limiting block 543 abuts against the driven block 531.

[0030] Through the above technical solution, when the driving groove 542 waits to engage with the next driven block 531, the limiting block 543 is located on the leaving side; when the driven block 531 separates from the driving groove 542, the limiting block 543 is located on the feeding side, and the driving groove 542 completes rotation during the process of waiting for the next driven block 531.

[0031] During the engagement process of the driven block 531 and the driving groove 542, it enters the driving groove 542 until it abuts against the limiting block 543, that is, the engagement is completed. The engagement has high precision, and the driving block 541 drives the driven block 531 to rotate with high consistency and high stability.

[0032] As a specific embodiment of the improvement, a rotary motor 34 and a rotary ring 35 are provided on the loading seat 3. The rotary motor 34 is fixed on the loading seat 3. The rotary motor 34 is fixed on the loading seat 3. The rotary ring 35 is rotatably arranged on the loading seat 3. The rotary ring 35 is coaxially arranged with the rotary disk 51. A rotary gear 341 is provided on the rotary motor 34. The rotary gear 341 meshes with the rotary ring 35.

[0033] Through the above technical solution, the rotary ring 35 supports the rotary disk 51 with high stability, reducing the axial pressure on the rotating shaft of the rotary motor 34 and extending the service life of the rotary motor 34. Moreover, by driving the rotary ring 35 to rotate through the rotary gear 341, the rotation angle of the rotary ring 35 can be controlled more precisely, and then the rotation amplitude of the rotary disk 51 can be controlled, which is convenient to control and use.

[0034] As a specific embodiment of the improvement, the driving mechanism 4 includes: A guide rail 41, fixedly arranged on the frame 1 and located below the loading seat 3; A slider 42, fixedly arranged on the lower side of the loading seat 3 and slidably connected to the guide rail 41; A moving motor 43, fixedly arranged on the frame 1. A moving wheel 431 is provided on the moving motor 43; A positioning block 44, fixedly arranged on the frame 1. A rotatable moving shaft 45 is provided in the positioning block 44; A driven wheel 46, arranged at the end of the moving shaft 45. The driven wheel 46 is connected to the moving wheel 431 by a belt; A fixed block 47, fixedly arranged on the frame 1. The moving shaft 45 is rotatably connected to the fixed block 47; A movable block 48, fixedly arranged on the loading seat 3. The movable block 48 is located between the fixed block 47 and the positioning block 44. The moving shaft 45 passes through the movable block 48 and is threadedly connected to the movable block 48.

[0035] Through the above technical solution, the driving process of the driving mechanism 4 driving the loading seat 3 is as follows: The moving motor 43 operates to drive the moving wheel 431 to rotate. The moving wheel 431 drives the driven wheel 46 to rotate through the belt. The rotation of the driven wheel 46 causes the moving shaft 45 to rotate. The rotation of the moving shaft 45 drives the movable block 48 to move through the thread, and then drives the loading seat 3 to move.

[0036] The loading seat 3 is connected to the frame 1 through the guide rail 41 and the slider 42, with small resistance and high precision during sliding.

[0037] The positions of the two ends of the moving shaft 45 are fixed by the positioning block 44 and the fixed block 47, making the position of the moving shaft 45 stable. The movable block 48 is located between the fixed block 47 and the positioning block 44, ensuring high stability during driving.

[0038] As a specific embodiment of the improvement, a waste slot 12 is provided in the frame 1, and a waste hole 13 is provided on the waste slot 12 for discharging waste. The cleaning mechanism 6 includes: A cleaning track 61, which is arranged in a circular closed manner along the waste slot 12. The cleaning track 61 is arranged in the frame 1 and encloses the loading seat 3 and the grinding mechanism 2; A cleaning belt 62, which is arranged on the cleaning track 61. The cleaning belt 62 slides cyclically along the track of the cleaning track 61. The movement track of the cleaning belt 62 passes through the waste hole 13, and the cleaning belt 62 is linked with the rotating disk 51; Brush bristles 63, which are arranged on the lower side of the cleaning belt 62, and the brush bristles 63 are in contact with the bottom of the waste slot 12.

[0039] Through the above technical solution, when the equipment runs to grind the brake disc, the rotating disk 51 rotates at intervals, and regularly transfers the brake disc on the next processing table 53 to the lower part of the grinding mechanism 2. During the rotation of the rotating disk 51, the cleaning belt 62 is driven to move along the cleaning track 61. The movement of the cleaning belt 62 drives the brush bristles 63 to move. The brush bristles 63 push the debris ground from the previous brake disc into the waste hole 13 and then discharge it to the outside, avoiding the accumulation of debris, keeping the internal environment clean, and improving the product qualification rate. And there is no need to stop the machine for cleaning, and the equipment can be used for a long time, further improving the production efficiency.

[0040] Specifically, the upper side of the waste hole 13 has an inclined guiding part, which expands the discharge area and guides the debris to enter, making the cleaning more thorough and further avoiding the accumulation of waste.

[0041] Specifically, the cleaning track 61 encloses both the loading seat 3 and the grinding mechanism 2, and there is no dead angle for cleaning.

[0042] Specifically, there are cleaning rods 65 at both ends of the rotating disk 51, which are combined with the cleaning groove 621, and can stably drive the cleaning belt 62 to rotate, thereby cleaning the waste.

[0043] As a specific embodiment of the improvement, a baffle 64 is provided on the frame 1. The baffle 64 extends along the track of the cleaning track 61 and encloses it. There is a notch 641 on the baffle 64. The notch 641 is located near the rotating disk 51 and outside the partition plate 11. There is a cleaning rod 65 on the outside of the rotating disk 51, and a cleaning groove 621 is provided on the cleaning belt 62. Part of the cleaning rod 65 is embedded in the cleaning groove 621.

[0044] Through the above technical solution, the baffle 64 protects the cleaning track 61 inside, avoiding the debris ground from entering the cleaning track 61, ensuring the use environment of the cleaning track 61, and extending the service life.

[0045] The notch 641 is located outside the partition plate 11. When the grinding mechanism 2 performs grinding, debris is blocked inside the frame 1. As the rotating disk 51 rotates, the cleaning rod 65 rotates. The cleaning rod 65 sequentially passes through the position of the notch 641 and engages and disengages with the cleaning groove 621 at the position of the notch 641, driving the cleaning belt 62 to move. The movement of the cleaning belt 62 further drives the bristles 63 to move, pushing the debris in the waste trough 12 into the waste hole 13, and then collecting them uniformly through a pipeline; there is no need to additionally set a driving source. As long as the grinding can be carried out stably, the cleaning can be carried out stably, reducing costs and having high stability during the operation of the equipment.

[0046] As a specific implementation of the improvement, a clamping groove 7 is provided on the side of the rotating disk 51, a clamping block 651 is provided on the cleaning rod 65, the clamping block 651 is slidably arranged vertically in the clamping block 651, a spring 71 is provided in the clamping groove 7, a separating electromagnet 72 is provided on the loading seat 3, the separating electromagnet 72 is located below the cleaning rod 65 near the position of the notch 641, and during the movement of the loading seat 3, the separating electromagnet 72 is always located within the notch 641.

[0047] Through the above technical solution, when adjusting the position of the loading seat 3, the separating electromagnet 72 operates, thereby driving the cleaning rod 65 to descend, so that the cleaning rod 65 is misaligned with the cleaning groove 621. At this time, the clamping block 651 descends, the spring 71 is compressed, and the driving mechanism 4 can smoothly drive the loading seat 3 to translate; after the loading seat 3 is adjusted in place, the separating electromagnet 72 is turned off, the spring 71 resets to drive the clamping block 651 to rise, thereby driving the cleaning rod 65 to rise and re-match with the cleaning groove 621.

[0048] Specifically, the notch 641 has a certain length range to meet the adjustment of the position of the loading seat 3.

[0049] As a specific implementation of the improvement, a combing rod 652 is provided on the cleaning rod 65, the combing rod 652 protrudes away from the rotating disk 51, and the combing rod 652 is located at the lower end position of the cleaning rod 65.

[0050] Through the above technical solution, when it is necessary to clean the bristles 63, by intermittently controlling the opening and closing of the separating electromagnet 72, the lifting of the cleaning rod 65 can be controlled, thereby driving the lifting of the combing rod 652. The combing rod 652 combs the bristles 63, and the bristles 63 can be cleaned during the process of grinding the brake disc without stopping for manual cleaning. The equipment can be used for a long time, further improving production efficiency.

[0051] Specifically, when not cleaning, the cleaning rod 65 is located above the bristles 63, and when cleaning the bristles 63, the cleaning rod 65 moves up and down on the bristles 63, thereby cleaning the bristles 63.
