DETAILED DESCRIPTION

[0036] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Embodiment 1

[0038] A disc brake pad production polishing device, such as Figure 1-Figure 8As shown, it includes a support column 1, the top outer wall of the support column 1 is rotatably connected to a turntable 2, the outer wall of the turntable 2 is provided with multiple groups of fixed clamping mechanisms 3 for clamping and positioning the brake pads, a fixed top plate 5 is provided above the support column 1, and a polishing mechanism 4 for grinding the brake pads is provided at the bottom of the top plate 5.

[0039] The fixed clamping mechanism 3 includes a support seat 7 and a clamping column 8. The support seat 7 is rotatably connected to the inner wall of the turntable 2. The clamping column 8 is fixed above the support seat 7, and the clamping column 8 matches the mounting hole of the brake pad.

[0040] The clamping column 8 is composed of a plurality of elastic claws 16 in a circular array. The elastic claws 16 are fixed to the top outer wall of the support seat 7 , and the inner side of the elastic claws 16 is matched with a same limiting column 14 through an inclined surface 15 .

[0041] When the device is in use, the mounting hole of the brake pad can be sleeved on the outside of the elastic claw 16, and then the brake pad can be placed on the top of the support seat 7. Subsequently, the turntable 2 rotates, driving the support seat 7 to rotate together to the bottom of the polishing mechanism 4, and then the polishing mechanism 4 starts to grind the brake pad. During the grinding, the support seat 7 will rotate in the opposite direction relative to the grinding direction. At this time, the limit column 14 moves upward relative to the elastic claw 16, and the elastic claw 16 is opened outward through the inclined surface 15, so that the mounting hole of the brake pad can be fixed by the elastic claw 16. At this time, the last polished brake pad can be removed from the top of another support seat 7, and the next brake pad to be polished can be placed on the top of the other support seat 7.

[0042] The device, by setting a multi-station working mode, can have polishing, loading and unloading stations respectively, so that the station switching can be achieved by utilizing the rotation of the turntable 1 2, and multiple stations can operate simultaneously, thereby improving production efficiency.

[0043] In addition, the device provides a clamping column 8 that cooperates with the brake pad, and uses the elastic claw 16 of the clamping column 8 to limit the brake pad, thereby increasing the convenience of taking and placing the brake pad and further improving production efficiency. During grinding, the cooperation between the limiting column 14 and the elastic claw 16 can be used to achieve outward expansion fixation of the elastic claw 16, thereby increasing the reliability of fixation and preventing the occurrence of large vibration amplitudes of the brake pad during grinding.

[0044] In order to solve the problem of operational convenience; Figure 3As shown, the inner wall of the support seat 7 is provided with a "U"-shaped cavity 12, and the inner wall of the "U"-shaped cavity 12 is symmetrically slidably connected to two counterweight pistons 11, and the two counterweight pistons 11 are buckled with springs 9 on the opposite sides, and a limiting ring 10 is fixed to the inner wall of the "U"-shaped cavity 12 located on the opposite side of the two counterweight pistons 11, and a force piston 13 is fixed to the bottom outer wall of the limiting column 14, and the force piston 13 is slidably connected to the inner cavity of the force piston 13.

[0045] When the support seat 7 rotates, it can drive the counterweight piston 11 to rotate. The counterweight piston 11 rotates and moves outward due to the centrifugal force, thereby compressing the gas in the inner cavity of the "U"-shaped cavity 12, and the pressure is transmitted to the force piston 13 through the gas, thereby driving the limit column 14 to rise.

[0046] The device, by providing a counterweight piston 11 and a "U"-shaped cavity 12, utilizes the rotation characteristics of the support seat 7 during grinding and polishing, combined with the centrifugal force applied to the counterweight piston 11 during rotation, so that the elastic claw 16 can synchronize the outward expansion and fixation of the brake pad with the rotation of the support seat 7, thereby eliminating the need for manual or electronic control, simplifying the control logic, and increasing operational convenience.

[0047] Analysis of centrifugal force control: Without considering various frictions, assuming that the mass of the counterweight piston 11 is M1, the initial rotation radius is R1, the rotation speed is V, and the sum of the gravity of the force-bearing piston 13 and the limit column 14 is M2, then the upward force on the limit column 14 is , g is the acceleration of gravity. Considering the friction, assuming that the friction between the weight piston 11, the force piston 13 and the "U" cavity 12 are F1 and F2 respectively, the upward force on the limit column 14 is .

[0048] In order to solve the rotation drive problem; such as Figure 5 As shown, a connecting column 18 is fixed to the outer wall of one end of the top plate 5 by bolts, the bottom of the connecting column 18 is fixed to the top of the support column 1 by bolts, and a motor 17 is fixed to the outer wall of the top of the top plate 5 by bolts, the outer wall of the output shaft of the motor 17 is connected to a driving shaft 25 through a coupling, and the end of the driving shaft 25 is connected to a gear 24 through a key.

[0049] The outer wall of the connecting column 18 is movably provided with a slide plate 21, the bottom outer wall of the slide plate 21 is fixed with a double-sided gear ring 23 by bolts, and the top outer wall of the turntable 2 is fixed with a gear ring 22 by bolts. The double-sided gear ring 23 can engage and disengage with the gear ring 22 and the gear 24 at the same time.

[0050] An electromagnet 19 is fixed to the outer wall of the connecting column 18, and a permanent magnet 20 is fixed to the top of the slide plate 21 by bolts.

[0051] The outer wall of the support seat 7 is provided with a tooth groove 6, and the gear 24 is meshed with the outer wall of the tooth groove 6 of the support seat 7 located at the polishing station.

[0052] When the support seat 7 rotates to the polishing station, the gear 24 meshes with the tooth groove 6 of the support seat 7. At this time, the motor 17 is started, and the gear 24 can be driven to rotate through the active shaft 25, thereby driving the support seat 7 to rotate. At the same time, when the station needs to be switched, current is passed into the inside of the electromagnet 19, so that a magnetic repulsion force is generated between the electromagnet 19 and the permanent magnet 20, so that the double-sided gear ring 23 is meshed between the gear ring 22 and the gear 24 by the magnetic repulsion force. At this time, the gear 24 can drive the gear ring 22 to rotate through the double-sided gear ring 23, thereby driving the turntable 2 to rotate, and realizing the station switching. After the switching is completed, a reverse current is passed into the electromagnet 19, which generates a magnetic field that attracts the permanent magnet 20, thereby separating the double-sided gear ring 23 from the gear ring 22 and the gear 24.

[0053] This device controls the engagement and separation of the support seat 7 and the gear 24 by utilizing the rotational movement of the support seat 7 when switching the workstation, so that the support seat 7 can automatically engage during polishing and automatically separate during loading and unloading, thereby realizing automatic control.

[0054] When the present embodiment is in use, the mounting hole of the brake pad can be sleeved on the outer side of the elastic claw 16, and then the brake pad can be placed on the top of the support seat 7. Subsequently, the turntable 2 rotates, driving the support seat 7 to rotate together to the bottom of the polishing mechanism 4, and then the polishing mechanism 4 starts to grind the brake pad. During the grinding, the support seat 7 will rotate in the opposite direction relative to the grinding direction. At this time, the limit column 14 moves upward relative to the elastic claw 16, and the elastic claw 16 is opened outward through the inclined surface 15, so that the mounting hole of the brake pad can be fixed by the elastic claw 16. At this time, the last polished brake pad can be removed from the top of another support seat 7, and the next brake pad to be polished can be placed on the top of another support seat 7. When the support seat 7 rotates to the polishing station, the gear 24 meshes with the tooth groove 6 of the support seat 7. At this time, the motor 17 starts, and the gear can be driven by the active shaft 25 to rotate. The wheel 24 rotates, thereby driving the support seat 7 to rotate. At the same time, when the work station needs to be switched, current is passed into the inside of the electromagnet 19, so that a magnetic repulsion force is generated between the electromagnet 19 and the permanent magnet 20, so that the double-sided gear ring 23 is meshed between the gear ring 22 and the gear 24 by using the magnetic repulsion force. At this time, the gear 24 can drive the gear ring 22 to rotate through the double-sided gear ring 23, thereby driving the turntable 2 to rotate, and realizing the work station switching. After the switching is completed, a reverse current is passed into the electromagnet 19, which generates a magnetic field attracted by the permanent magnet 20, thereby separating the double-sided gear ring 23 from the gear ring 22 and the gear 24, and when the support seat 7 rotates, it can drive the counterweight piston 11 to rotate. The counterweight piston 11 rotates and moves outward due to the centrifugal force, thereby compressing the gas in the inner cavity of the "U"-shaped cavity 12, and the pressure is transmitted to the force piston 13 through the gas, thereby driving the limit column 14 to rise.

[0055] A disc brake pad production polishing device, such as Figure 1 , 6 As shown in , 7 and 8, in order to solve the welding problem; this embodiment makes the following improvements on the basis of embodiment 1: the polishing mechanism 4 includes an outer shaft 27, a turntable 28, an inner shaft 29 and a lifting plate 31, the outer shaft 27 is rotatably connected to the bottom inner wall of the top plate 5, the inner shaft 29 is transmission-matched to the bottom inner wall of the outer shaft 27, the turntable 28 is fixed to the outer wall of the outer shaft 27, and the lifting plate 31 is fixed to the bottom end of the inner shaft 29, and the bottom outer wall of the lifting plate 31 is fixed with a grinding sand disc 30 for polishing.

[0056] The inner wall of the outer shaft 27 is provided with a key-shaped groove 32 , and the outer wall of the inner shaft 29 is welded with a key-shaped protrusion 33 , the key-shaped groove 32 and the key-shaped protrusion 33 are loosely matched, and the end of the inner shaft 29 is buckled with a spring 2, and the other end of the spring 2 is buckled with the inner wall of the outer shaft 27 .

[0057] The outer shaft 27 and the driving shaft 25 are coupled to each other through a synchronous belt 26 .

[0058] When the driving shaft 25 rotates, it can drive the outer shaft 27 to rotate through the synchronous belt 26, thereby driving the inner shaft 29 to rotate through the key groove 32 and the key protrusion 33, so that the lifting plate 31 drives the grinding sand disc 30 to rotate, and the direction of rotation of the grinding sand disc 30 is the same as the direction of rotation of the driving shaft 25, and opposite to the direction of rotation of the support seat 7.

[0059] The radial inner wall of the turntable 28 is provided with a slide groove 35, the inner wall of the slide groove 35 is slidably connected with a counterweight slider 34, the bottom of the counterweight slider 34 is rotatably connected with a connecting rod 38, and the other end of the connecting rod 38 is rotatably connected to the top of the lifting plate 31.

[0060] The outer circumferential wall of the second turntable 28 at the slide groove 35 is connected with an adjusting bolt 37 through a thread, and the outer wall of the adjusting bolt 37 is connected with a locking nut 36 through a thread.

[0061] When the turntable 28 rotates, it can drive the counterweight slider 34 to rotate, so that the counterweight slider 34 is moved outward by the centrifugal force when the counterweight slider 34 rotates, and then the lifting plate 31 is driven down through the connecting rod 38.

[0062] This device, by setting structures such as a counterweight slider 34 and a connecting rod 38, can, on the one hand, utilize the rotation of the turntable 28 and the lifting plate 31 itself to realize the lifting and lowering of the lifting plate 31, saving the lifting power and structural layout; on the other hand, since the centrifugal force is a flexible force, the downward pressure of the lifting plate 31 can be controlled by controlling the rotation speed, thereby accurately controlling the grinding pressure, and by setting an adjusting bolt 37, it can limit the maximum displacement of the counterweight slider 34, thereby achieving accurate control of the grinding degree.

[0063] When this embodiment is in use, when the driving shaft 25 rotates, it can drive the outer shaft 27 to rotate through the synchronous belt 26, thereby driving the inner shaft 29 to rotate through the key-shaped groove 32 and the key-shaped protrusion 33, so that the lifting plate 31 drives the grinding sand disc 30 to rotate, and the direction of rotation of the grinding sand disc 30 is the same as the direction of rotation of the driving shaft 25, and is opposite to the direction of rotation of the support seat 7. When the turntable 28 rotates, it can drive the counterweight slider 34 to rotate, thereby utilizing the centrifugal force exerted on the counterweight slider 34 when it rotates to move the counterweight slider 34 outward, and then drive the lifting plate 31 to descend through the connecting rod 38.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
