Description

Technical Field

[0001] The invention relates to the technical field of brake disc press-fitting, and in particular to an automatic brake disc positioning and press-fitting device. Background Art

[0002] The brake disc also rotates when the car is moving. The braking force is usually generated by the brake caliper clamping the brake disc. When you step on the brake, it clamps the brake disc to slow down or stop the car. The brake disc has a good braking effect and is easier to maintain than drum brakes.

[0003] Currently, when press-fitting a brake disc, the installation component is usually placed on the brake disc manually, and then press-fitted with a hydraulic cylinder to press-fit the installation component into the brake disc. However, manual placement will result in errors. If the installation component is offset, the installation component cannot be pressed into the brake disc during press-fitting, which will cause the installation component and the brake disc to be squeezed and deformed, causing damage. Therefore, workers are required to repeatedly confirm and adjust the placement position every time they press-fit, which is very troublesome. In addition, if there is dust inside the brake disc during press-fitting, it may affect the operation of the installation component after press-fitting.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0030] Reference Figure 1 - Figure 8 , an automated brake disc positioning and pressing device, comprising a base 1, a brake disc 2 and a mounting assembly 3, the upper end of the base 1 is fixedly connected to an annular pressing table 4 through a plurality of fixed shafts, the side wall of the base 1 is fixedly connected to a mounting plate 5 through a bracket, the upper end of the mounting plate 5 is fixedly connected to a hydraulic cylinder 6, the movable end of the hydraulic cylinder 6 passes through the top of the mounting plate 5 and is fixedly connected to a pressing die 7;

[0031] The positioning mechanism includes an annular plate 8 fixedly connected to the side wall of the die 7, four first arc-shaped T-slots 81 are opened at the lower end of the annular plate 8, four magnetic T-shaped blocks 82 are slidably connected to the inner walls of the four first arc-shaped T-slots 81, four first T-shaped rods 9 are fixedly connected to the lower ends of the four magnetic T-shaped blocks 82, four first T-shaped rods 9 are slidably connected to the side walls of the four first T-shaped rods 9, an annular mounting frame 10 is slidably connected to the side walls of the four first T-shaped rods 9, a first spring 11 is sleeved on the side wall of the first T-shaped rod 9, two ends of the first spring 11 are respectively fixedly connected to the first T-shaped rod 9 and the lower end of the annular mounting frame 10, four L-shaped rods 12 are slidably connected to the side wall of the annular mounting frame 10, one end of the four L-shaped rods 12 are fixedly connected to a slider 13, the side wall of the slider 13 is fixedly connected to a slide cylinder 14, the inner wall of the slide cylinder 14 is slidably connected to a positioning rod 15, and one end of the positioning rod 15 is fixedly connected to a positioning plate 16.

[0032] The positioning mechanism also includes four second arc-shaped T-slots 19 opened at the lower end of the annular plate 8, the inner walls of the four second arc-shaped T-slots 19 are slidably connected with the first T-block 20, the lower end of the first T-block 20 is fixedly connected with a rack 21, the inner wall of the second arc-shaped T-slot 19 is fixedly connected with a third spring 22, the other end of the third spring 22 is fixedly connected to the side wall of the first T-block 20, the side wall of the annular mounting frame 10 is rotatably connected with four lead screws 23, the side wall of the lead screw 23 is threadedly connected to the slider 13, one end of the lead screw 23 passes through the side wall of the annular mounting frame 10 and is fixedly connected with a first gear 24, and the first gear 24 is meshed with the rack 21.

[0033] It should be noted that, during press-fitting, the positioning plate 16 has been completely moved into place before the die 7 contacts the mounting assembly 3 , and at this time, the rack 21 has been separated from the first gear 24 and is no longer meshed.

[0034] Further, the brake disc 2 is placed on the annular press-fitting table 4, and then the mounting assembly 3 is placed on the brake disc 2, and then the hydraulic cylinder 6 is driven to extend, driving the die 7 and the annular plate 8 to move downward synchronously, and the mounting assembly 3 is started to be press-fitted. When the annular plate 8 moves downward, it will synchronously drive the rack 21 to move downward, and the rack 21 will drive the first gear 24 to rotate, and then drive the lead screw 23 to rotate, drive the slider 13 to move in the direction close to the brake disc 2, and then drive the slide 14 to move, drive the positioning rod 15 to move, and then drive the positioning plate 16 to move close to The brake disc 2 moves in the direction of the positioning plate 16, and when the positioning plate 16 moves to fit with the mounting component 3, it will push the mounting component 3 to move. Since four positioning plates 16 are provided, and they are symmetrically arranged with the center axis of the annular press-fitting table 4, the mounting component 3 will move to the center under the push of the positioning plate 16, so that the mounting component 3 can be accurately aligned with the mounting port of the brake disc 2. Therefore, when placing the mounting component 3, it is only necessary to place the mounting component 3 on the upper end of the brake disc 2, and there is no need to repeatedly confirm the position for placement. It is more time-saving and labor-saving to use, and the processing efficiency is improved.

[0035] One end of the positioning rod 15 located in the slide 14 is fixedly connected to a conductive sheet 25, and a second spring 17 is fixedly connected to the side wall of the conductive sheet 25. The other end of the second spring 17 is fixedly connected to the inner wall of the slide 14, and an insulating sleeve is provided on the side wall of the second spring 17, which plays a good insulating role. A first annular conductive plate 26 and a second annular conductive plate 27 are embedded in the inner wall of the slide 14, and a fourth spring 28 is fixedly connected to the inner wall of the first arc-shaped T-slot 81, and the other end of the fourth spring 28 is fixedly connected to the side wall of the magnetic T-shaped block 82. An electromagnet 29 is fixedly connected to the inner wall of the first arc-shaped T-slot 81. The hydraulic cylinder 6, the first annular conductive plate 26, the conductive sheet 25, the power supply and the external warning light are connected in series through wires, and the conductive sheet 25, the second annular conductive plate 27, the electromagnet 29, the power supply and the external warning light are connected in series through wires.

[0036] It should be noted that the second spring 17 has a relatively large stiffness coefficient, and when the positioning plate 16 pushes the mounting assembly 3 to move normally for positioning, the second spring 17 will not be compressed.

[0037] Furthermore, when positioning the mounting assembly 3, if the size of the mounting assembly 3 is too large, the positioning plate 16 will push it to position. When the mounting assembly 3 is in place, the positioning plate 16 will squeeze the second spring 17 through the positioning rod 15. At this time, the positioning rod 15 will drive the conductive sheet 25 to move to the right (as shown in the attached figure). Figure 5As shown), the conductive sheet 25 moves to contact the second annular conductive plate 27, and it will separate from the first annular conductive plate 26, the hydraulic cylinder 6 will be powered off and stop extending, and at this time the electromagnet 29 will be energized to generate magnetism, generating magnetic attraction on the magnetic T-shaped block 82, thereby driving the magnetic T-shaped block 82 to slide in the first arc-shaped T-slot 81, and the magnetic T-shaped block 82 will drive the annular mounting frame 10 to rotate a certain angle through the first T-shaped rod 9, thereby driving the positioning plate 16 to rotate a certain angle, so that the positioning plate 16 contacts with different positions of the mounting component 3. If the mounting component 3 is too large, then no matter where the positioning plate 16 contacts with the mounting component 3, the conductive sheet 25 will contact with the second annular conductive plate 27, and then the external warning light will remain powered on and light up. The staff can observe whether the warning light remains on. If it is on for a long time, it means that the mounting component 3 is too large, and the mounting component 3 may be unqualified and needs to be replaced.

[0038] It is worth mentioning that if there is a protrusion on the surface of the mounting component 3, the warning light will also light up when the positioning plate 16 contacts the protrusion. However, when the positioning plate 16 rotates a certain angle and contacts other positions of the mounting component 3, the positioning plate 16 separates from the protrusion and resets. At this time, the conductive sheet 25 separates from the second annular conductive plate 27 and contacts the first annular conductive plate 26 again, and the warning light will go out again. At this time, the electromagnet 29 will be powered off and lose its magnetism, and the magnetic T-shaped block 82 will reset under the action of the fourth spring 28, driving the positioning plate 16 to rotate and reset. At this time, the positioning plate 16 contacts the protrusion again, and then the second annular conductive plate 27 contacts the conductive sheet 25 again, and the warning light lights up again. Therefore, the warning light will flash continuously at this time. If the staff observes this situation, the surface of the surface mounting component 3 is uneven and needs to be replaced and reprocessed. Therefore, when the positioning plate 16 positions the mounting component 3, the mounting component 3 can also be inspected to ensure that the pressed mounting component 3 is a qualified product.

[0039] A lubrication mechanism is installed on the annular mounting frame 10, and the lubrication mechanism includes four oil pump cylinders 30 fixedly connected to the side wall of the annular mounting frame 10 through a bracket, the inner walls of the four oil pump cylinders 30 are sealed and slidably connected with a sliding plug 31, and the inner wall of the oil pump cylinder 30 is fixedly connected with a one-way oil inlet pipe 32, and the other end of the one-way oil inlet pipe 32 is connected to an external container storing lubricating oil. The one-way oil inlet pipe 32 is made of a hose, and the one-way oil inlet pipe 32 only allows external lubricating oil to enter the oil pump cylinder 30.

[0040] The lubrication mechanism also includes an oil inlet chamber 33 opened in the positioning plate 16, and a plurality of oil outlet holes 34 are opened on the inner wall of the oil inlet chamber 33. The oil pump cylinder 30 is connected to the oil inlet chamber 33 through a one-way oil outlet pipe 35, and the one-way oil outlet pipe 35 only allows the lubricating oil in the oil pump cylinder 30 to enter the oil inlet chamber 33.

[0041] Furthermore, when the positioning plate 16 is positioned, the movement of the slider 13 will synchronously drive the movement of the L-shaped rod 12, and then drive the movement of the sliding plug 31, squeezing the lubricating oil in the pump oil cylinder 30 into the oil inlet chamber 33 through the one-way oil outlet pipe 35, and then the lubricating oil flows out through multiple oil outlet holes 34 to lubricate the positioning plate 16, reduce the friction between the positioning plate 16 and the mounting assembly 3, and thus facilitate the pressing of the mounting assembly 3 into the brake disc 2, and when the positioning plate 16 rotates, the mounting assembly 3 will not rotate with the positioning plate 16.

[0042] A cleaning mechanism is installed on the base 1, and the cleaning mechanism includes a second T-bar 36 slidably connected to the upper end of the base 1, the second T-bar 36 is arranged to penetrate the base 1, and the side wall of the second T-bar 36 is sleeved with a fifth spring 47, and the two ends of the fifth spring 47 are respectively fixedly connected to the second T-bar 36 and the lower end of the base 1, and the upper end of the second T-bar 36 is fixedly connected to a rifle rod 37, and the upper end of the rifle rod 37 is fixedly connected to a fixing plate 38, and the side wall of the fixing plate 38 is fixedly connected to a dust cylinder 39, and a plurality of dust suction holes 40 are provided on the inner wall of the dust cylinder 39, and the upper end of the base 1 is rotatably connected to a rotating shaft 41, and the upper end of the rotating shaft 41 penetrates the inner bottom of the dust cylinder 39 and is fixedly connected to a plurality of fan blades 42, and the inner bottom of the dust cylinder 39 has two dust exhaust holes 48 symmetrically provided.

[0043] The cleaning mechanism also includes a T-shaped circular groove 43 opened at the upper end of the base 1, and two third T-shaped rods 44 are symmetrically and slidably connected to the inner wall of the T-shaped circular groove 43. The upper ends of the two third T-shaped rods 44 are commonly fixedly connected to a second gear 45, the side wall of the rifle rod 37 is threadedly connected to the second gear 45, and the side wall of the rotating shaft 41 is fixedly connected to a third gear 46, and the second gear 45 is meshingly connected to the third gear 46.

[0044] Furthermore, after the positioning plate 16 has positioned the mounting component 3, the hydraulic cylinder 6 will continue to extend and drive the die 7 to move downward, and the die 7 will begin to contact the upper end of the mounting component 3 to press-fit the mounting component 3. At this time, the rack 21 has been separated from the first gear 24 and is no longer engaged. During the pressing process, the mounting component 3 will be pressed into the brake disc 2, and when the mounting component 3 is pressed downward, it will push the dust extraction cylinder 39 to move downward, thereby driving the fixing plate 38 to move downward, driving the rifle rod 37 to move downward, and then driving the second gear 45 to rotate, driving the third gear 46 to rotate, and then driving the rotating shaft 41 to rotate, driving the multiple fan blades 42 to rotate, thereby generating a suction force, and the dust and impurities in the brake disc 2 will be sucked into the dust extraction cylinder 39 through the multiple dust suction holes 40, and then the dust and impurities will be discharged through the dust exhaust holes 48, so that the dust and impurities in the brake disc 2 will be synchronously cleared during the pressing process to avoid affecting the installation of the mounting component 3.

[0045] In the present invention, the brake disc 2 is placed on the annular press-fitting table 4, and then the mounting assembly 3 is placed on the brake disc 2, and then the hydraulic cylinder 6 is driven to extend, driving the die 7 and the annular plate 8 to move downward synchronously, and the mounting assembly 3 is started to be press-fitted. When the annular plate 8 moves downward, it will synchronously drive the rack 21 to move downward, and the rack 21 will drive the first gear 24 to rotate, and then drive the lead screw 23 to rotate, drive the slider 13 to move in the direction close to the brake disc 2, and then drive the slide 14 to move, drive the positioning rod 15 to move, and then drive the positioning plate 16 to move close to The brake disc 2 moves in the direction of the positioning plate 16, and when the positioning plate 16 moves to fit with the mounting component 3, it will push the mounting component 3 to move. Since four positioning plates 16 are provided, and they are symmetrically arranged with the center axis of the annular press-fitting table 4, the mounting component 3 will move to the center under the push of the positioning plate 16, so that the mounting component 3 can be accurately aligned with the mounting port of the brake disc 2. Therefore, when placing the mounting component 3, it is only necessary to place the mounting component 3 on the upper end of the brake disc 2, and there is no need to repeatedly confirm the position for placement. It is more time-saving and labor-saving to use, and the processing efficiency is improved.

[0046] When the positioning plate 16 has completed the positioning of the mounting component 3, the hydraulic cylinder 6 will continue to extend and drive the die 7 to move downward, and the die 7 begins to contact the upper end of the mounting component 3 to press the mounting component 3. At this time, the rack 21 has been separated from the first gear 24 and is no longer engaged. During the pressing process, the mounting component 3 will be pressed into the brake disc 2, and when the mounting component 3 is pressed downward, it will push the dust extraction cylinder 39 to move downward, thereby driving the fixing plate 38 to move downward, driving the rifle rod 37 to move downward, and then driving the second gear 45 to rotate, driving the third gear 46 to rotate, and then driving the rotating shaft 41 to rotate, driving the multiple fan blades 42 to rotate, thereby generating a suction force, and the dust and impurities in the brake disc 2 will be sucked into the dust extraction cylinder 39 through the multiple dust suction holes 40, and then the dust and impurities will be discharged through the dust exhaust hole 48, so that the dust and impurities in the brake disc 2 will be synchronously removed during the pressing process to avoid affecting the installation of the mounting component 3.

[0047] In addition, when positioning the mounting assembly 3, if the size of the mounting assembly 3 is too large, the positioning plate 16 will push it to position. When the mounting assembly 3 is in place, the positioning plate 16 will squeeze the second spring 17 through the positioning rod 15. At this time, the positioning rod 15 will drive the conductive sheet 25 to move to the right (as shown in the attached figure). Figure 5As shown), the conductive sheet 25 moves to contact the second annular conductive plate 27, and it will separate from the first annular conductive plate 26, the hydraulic cylinder 6 will be powered off and stop extending, and at this time the electromagnet 29 will be energized to generate magnetism, generating magnetic attraction on the magnetic T-shaped block 82, thereby driving the magnetic T-shaped block 82 to slide in the first arc-shaped T-slot 81, and the magnetic T-shaped block 82 will drive the annular mounting frame 10 to rotate a certain angle through the first T-shaped rod 9, thereby driving the positioning plate 16 to rotate a certain angle, so that the positioning plate 16 contacts with different positions of the mounting component 3. If the mounting component 3 is too large, then no matter where the positioning plate 16 contacts with the mounting component 3, the conductive sheet 25 will contact with the second annular conductive plate 27, and then the external warning light will remain powered on and light up. The staff can observe whether the warning light remains on. If it is on for a long time, it means that the mounting component 3 is too large, and the mounting component 3 may be unqualified and needs to be replaced.

[0048] In addition, if there is a protrusion on the surface of the mounting component 3, the warning light will also be turned on when the positioning plate 16 contacts the protrusion. However, when the positioning plate 16 rotates a certain angle and contacts other positions of the mounting component 3, the positioning plate 16 separates from the protrusion and resets. At this time, the conductive sheet 25 separates from the second annular conductive plate 27 and contacts the first annular conductive plate 26 again, and the warning light will go out again. At this time, the electromagnet 29 will be powered off and lose its magnetism, and the magnetic T-shaped block 82 will reset under the action of the fourth spring 28, driving the positioning plate 16 to rotate and reset. At this time, the positioning plate 16 contacts the protrusion again, and then the second annular conductive plate 27 contacts the conductive sheet 25 again, and the warning light will light up again. Therefore, the warning light will flash continuously at this time. If the staff observes this situation, the surface of the surface mounting component 3 is uneven and needs to be replaced and reprocessed. Therefore, when the positioning plate 16 positions the mounting component 3, the mounting component 3 can also be inspected to ensure that the pressed mounting component 3 is a qualified product.

[0049] When the positioning plate 16 is positioned, the movement of the slider 13 will synchronously drive the L-shaped rod 12 to move, and then drive the sliding plug 31 to move, squeezing the lubricating oil in the pump oil cylinder 30 into the oil inlet chamber 33 through the one-way oil outlet pipe 35, and then the lubricating oil flows out through multiple oil outlet holes 34 to lubricate the positioning plate 16, reduce the friction between the positioning plate 16 and the mounting assembly 3, and thus facilitate the pressing of the mounting assembly 3 into the brake disc 2, and when the positioning plate 16 rotates, the mounting assembly 3 can not rotate with the positioning plate 16, and when the pressing is completed, the hydraulic cylinder 6 shortens and resets, which will drive the die 7 and the annular plate 8 to move upward and reset, and when the rack 21 moves to mesh with the first gear 24, it will drive the lead screw 23 to rotate in the opposite direction, and then drive the positioning plate 16 to reset, and at this time the sliding plug 31 will also reset, during this process, the external lubricating oil will be drawn into the pump oil cylinder 30 through the one-way oil inlet pipe 32 for storage for standby use.
