Description

Technical Field

[0001] The invention belongs to the technical field of brake pad manufacturing, and in particular relates to a grooving device for automobile brake pads. Background Art

[0002] Brake pads are key components in automotive braking systems, and their slot design significantly impacts heat dissipation, noise reduction, and braking performance. Currently, common brake pad slotting styles on the market primarily include curved slots and linear slots. Different slotting styles correspond to different functional characteristics. For example, curved slots excel in dispersing brake pressure and reducing noise, while linear slots offer excellent chip removal and basic heat dissipation. However, existing brake pad grooving devices generally have the problem of single function, that is, one device is only suitable for one specific grooving form. When different forms of grooving processing are required on the brake pad, the operator has to replace the corresponding grooving device or even adjust the structure of the entire processing equipment. This not only leads to cumbersome equipment operation procedures and low processing efficiency, but also makes the utilization rate of the device low, increasing the company's equipment purchase and maintenance costs. In addition, frequent replacement of devices may also introduce installation errors, affecting the accuracy and quality of the brake pad grooving, and thus adversely affecting the overall performance of the vehicle's braking system. Therefore, there is an urgent need to develop an automobile brake pad grooving device that is compatible with multiple grooving forms to improve the versatility and processing efficiency of the equipment. Summary of the Invention

[0006] Furthermore, the driving assembly includes a driving connecting plate, a driving shaft, a driving gear and a worm gear; the driving connecting plate is fixed on the rotating plate, the driving shaft is rotatably connected to the driving connecting rod, the driving gear and the worm gear are respectively coaxially fixed on the driving shaft, and the limiting member is a rack, which is engaged with the driving gear.

[0007] Furthermore, the one-way component includes a one-way fixed seat, a worm and a first bevel gear; the one-way fixed seat is fixed on the rotating plate, the worm is rotatably connected to the one-way fixed seat, and can drive the worm wheel in one direction; the first bevel gear is coaxially fixed on the worm and can drive the transmission component to rotate.

[0008] Furthermore, the transmission assembly includes a transmission connecting plate, a transmission connecting shaft, a transmission gear and a second bevel gear; the transmission connecting plate is fixed on the rotating plate, the transmission rotating shaft is rotatably connected to the transmission connecting plate, the transmission gear and the second bevel gear are respectively coaxially fixed on the transmission connecting shaft, the movement of the driven assembly can drive the transmission gear to rotate, and the first bevel gear and the second bevel gear are engaged.

[0009] Furthermore, the driven assembly includes a driven rack, a driven connecting rod and an arc plate; the driven rack is slidably connected to the rotating plate and is connected to the arc plate through the driven connecting rod, the driven rack is meshed with the transmission gear, and the pushing assembly can drive the driven rack to slide by pushing the arc plate.

[0010] Furthermore, the pushing assembly includes a pushing slide rod, a pushing rod, a positioning connecting plate, a positioning rod and a pushing connecting plate; a second slide groove is provided on the mounting frame, the pushing slide rod is slidably connected to the second slide groove, the positioning connecting plate is fixed on the pushing slide rod, the positioning rod can be lifted and slidably connected to the positioning connecting plate and can be inserted into the positioning hole; the pushing rod is fixed on the pushing slide rod and can push the arc plate to move; the pushing slide rod is connected to the concave slide groove through the pushing connecting plate.

[0011] Furthermore, a connecting plate is provided, and the limiting frame is slidably provided on the mounting frame and is connected to the driven rack via the connecting plate.

[0012] Furthermore, the slotting assembly includes a slider, a slotting motor, a slotting knife and a limit rod; the slider is slidably connected in the first slide groove, the slotting motor is fixedly provided at the bottom of the slider, and the slotting knife is coaxially fixedly provided on the output shaft of the slotting motor; the limit rod is fixedly provided at the top of the slider, and the two concave slot plates can abut against the limit rod.

[0013] The device of the present application is used as follows: in the initial state, the two concave groove plates are away from the limiting rod, and the two limiting members simultaneously abut against the slider to clamp the slider. Moreover, due to the meshing of the limiting members and the driving gear, the limiting members will continue to remain in the clamped state under the action of the worm gear mechanism, and arc-shaped grooves will be formed as the rotating plate rotates; When linear slotting is required, the two pushing slide bars are brought close to each other and the positioning rod is inserted into the positioning hole to limit the movement of the pushing slide bar. During the movement of the pushing slide bar, the pushing rod pushes the arc plate to move toward the limit rod, so that the driven rack slides toward the limit rod, and then drives the worm to rotate through the transmission assembly, so that the worm gear rotates and drives the two limit members to move away from the slider. The slider without restriction can slide in the first slide groove, and the limit rod at the top of the slider is restricted by the two concave groove plates and can only slide along the groove inside the concave groove plates. Therefore, when the rotating plate rotates at this time, the sliding block slides left and right in the first slide groove, and its top is interfered by the concave groove plate and moves back and forth in a straight line, and the movement of the slotting knife is forward and backward; When it is necessary to switch to arc grooving again, the positioning of the positioning rod on the push slide is released, and the driven rack is pulled outward, so that the worm gear drives the limit member to clamp the slide again, thereby realizing arc grooving.

[0014] Compared with the prior art, the advantages of the present invention include: In this application, when arc-shaped grooving is required, the driving mechanism is controlled so that the two limiting members approach and clamp the grooving assembly, limiting the position of the grooving assembly in the first slide groove so that it cannot slide. As a result, when the rotating plate rotates, the moving trajectory of the grooving assembly is an arc, thereby arc-shaped grooving can be performed on the brake pad. The position of the limiting member is controlled in one direction by the driving mechanism, so that when the driving mechanism drives the two concave groove plates to abut against each other and form a long annular plate, the two limiting members are simultaneously driven away from each other, so that the slotting assembly can slide in the first sliding groove, so that when the rotating plate rotates, the slotting assembly moves linearly along the concave groove plate, thereby opening a linear groove on the brake pad; The present application switches the motion trajectory of the slotting component through a driving mechanism, so that it can adjust different slotting methods according to slotting requirements.

Unless otherwise specified, the dimensions, materials, and manufacturing processes of the various components suitable for the automobile brake pad grooving device in the embodiments of the present invention can be selected according to specific circumstances and are not specifically limited or explained herein.

[0024] Furthermore, in order to provide the public with a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.

[0025] Please also refer to Figure 1-Figure 3 , this embodiment provides a vehicle brake pad grooving device, including a mounting frame 1, a limiting frame 13, a driving motor 14, a rotating plate 15, a grooving assembly 2, a limiting member 3, a concave groove plate 31 and a driving mechanism 4; The limiting frame 13 and the drive motor 14 are respectively mounted on the mounting frame 1. The rotating plate 15 is connected to the output shaft of the drive motor 14. The rotating plate 15 is provided with a first slide 151, and the slotting assembly 2 is slidably mounted within the first slide 151. It should be understood that the mounting frame 1 has a lower mounting surface and an upper mounting surface, with the limiting frame 13 disposed on the lower mounting surface and the drive motor 14 disposed on the upper mounting surface. The brake pad to be slotted is placed on the limiting frame 13 and secured thereto. The slotting assembly 2 can pass over the brake pad as the rotating plate 15 rotates, thereby slotting the brake pad. It should be understood that the drive motor 14 is a servo motor and can rotate forward or reverse according to the operator's operation.

[0026] Two sets of limiting members 3 are provided opposite to each other and are slidably arranged on the rotating plate 15. The two limiting members 3 can clamp the slotting assembly 2; that is, the slotting assembly 2 is clamped by the limiting members 3, so that the slotting assembly 2 always maintains the same distance from the driving motor 14 during the process of rotating with the rotating plate 15, so that its motion trajectory is arc-shaped.

[0027] The concave groove plates 31 are slidably arranged on the mounting frame 1 and are provided in two groups opposite to each other. When the two concave groove plates 31 abut against each other, they can limit the movement of the slotting component 2 between the two concave groove plates 31; specifically, when the two concave groove plates 31 abut against each other, a long annular plate is formed, and both sides of the slotting component 2 abut against the inner sides of the two concave groove plates 31 and move in a straight line within the groove of the long annular plate.

[0028] The drive mechanism 4 is disposed on the rotating plate 15 and can unidirectionally change the position of the clamping member. The drive mechanism 4 can move the two limiting members 3 away from the slot assembly 2 while simultaneously causing the two concave slot plates 31 to abut. The drive mechanism 4 can then be fixed at the point where the two concave slot plates 31 abut. Specifically, when the two concave slot plates 31 approach each other, the two limiting members 3 move away from each other, allowing the slot assembly 2 to slide within the first chute 151 while being restrained by the two concave slot plates 31. As the rotating plate 15 rotates, the slot assembly 2 is restrained by the two concave slot plates 31 and can only move along the concave slot plates 31 while simultaneously moving within the first chute 151. It should also be understood that the drive mechanism 4 unidirectionally controls the position of the limiting members 3, meaning that movement of the limiting members 3 cannot cause the drive mechanism 4 to move.

[0029] In this application, when arc-shaped grooving is required, the driving mechanism 4 is controlled to make the two limiting members 3 approach and clamp the grooving assembly 2, limiting the position of the grooving assembly 2 in the first sliding groove 151 so that it cannot slide. As a result, when the rotating plate 15 rotates, the moving trajectory of the grooving assembly 2 is an arc, thereby making it possible to perform arc-shaped grooving on the brake pad. The position of the limiting member 3 is unidirectionally controlled by the driving mechanism 4, so that when the driving mechanism 4 drives the two concave groove plates 31 to abut against each other and form a long annular plate, the two limiting members 3 are simultaneously driven away from each other, so that the slotting assembly 2 can slide in the first sliding groove 151. As a result, when the rotating plate 15 rotates, the slotting assembly 2 moves linearly along the concave groove plates 31, thereby forming a linear groove on the brake pad. The present application switches the motion trajectory of the slotting assembly 2 through the driving mechanism 4 so that it can adjust different slotting methods according to slotting requirements.

[0030] In other embodiments, the driving mechanism 4 includes a pushing assembly 5, a driving assembly 6, a one-way assembly 7, a transmission assembly 8, and a driven assembly 9. The pushing assembly 5 is slidably mounted on the mounting frame 1 and can drive the concave groove plate 31 to move. The mounting frame 1 is provided with a positioning hole 12, and the pushing assembly 5 can be fixed in position by inserting into the positioning hole 12. The driving assembly 6, the one-way assembly 7, and the transmission assembly 8 are respectively rotatably mounted on the rotating plate 15 and can drive the limiter 3 to move. The rotation of the one-way assembly 7 can unidirectionally drive the driving assembly 6 to rotate and can also simultaneously drive the transmission assembly 8 to rotate. The driven assembly 9 is slidably mounted on the rotating plate 15. When the pushing assembly 5 drives the concave groove plate 31 to approach, the transmission assembly 8 can be driven to rotate via the driven assembly 9. That is, the driven assembly 9 drives the transmission assembly 8 to rotate, the transmission assembly 8 drives the one-way assembly 7 to rotate, and the one-way assembly 7 drives the driving assembly 6 to rotate, thereby driving the limiter 3 to move unidirectionally, thereby achieving the purpose of unidirectionally adjusting the clamping state of the slotting assembly 2 as the concave groove plate 31 approaches.

[0031] In other embodiments, the drive assembly 6 includes a drive connecting plate 61, a drive shaft 62, a drive gear 63, and a worm gear 64; the drive connecting plate 61 is fixed to the rotating plate 15, the drive shaft 62 is rotatably connected to the drive connecting rod, the drive gear 63 and the worm gear 64 are coaxially fixed to the drive shaft 62, and the limiter 3 is a rack that meshes with the drive gear 63. It should be understood that the one-way assembly 7 can drive the worm gear 64 to rotate in one direction, and the limiter 3 is always meshed with the drive gear 63.

[0032] In other schemes, the one-way component 7 includes a one-way fixed seat 71, a worm 72 and a first bevel gear 73; the one-way fixed seat 71 is fixed on the rotating plate 15, the worm 72 is rotatably connected to the one-way fixed seat 71, and can drive the worm gear 64 in one direction; the first bevel gear 73 is coaxially fixed on the worm 72, and can drive the transmission component 8 to rotate.

[0033] In other embodiments, the transmission assembly 8 includes a transmission connecting plate 81, a transmission connecting shaft 82, a transmission gear 83, and a second bevel gear 84. The transmission connecting plate 81 is fixed to the rotating plate 15, and the transmission rotating shaft is rotatably connected to the transmission connecting plate 81. The transmission gear 83 and the second bevel gear 84 are respectively coaxially fixed to the transmission connecting shaft 82. The movement of the driven assembly 9 can drive the transmission gear 83 to rotate, and the first bevel gear 73 and the second bevel gear 84 are engaged. Specifically, when the pushing assembly 5 drives the concave groove plate 31 to approach, it drives the driven assembly 9 to slide toward the groove assembly 2, and then drives the first bevel gear 73 to rotate via the transmission gear 83, thereby causing the worm 72 to drive the worm wheel 64 to rotate, causing the limit member 3 to move away from the groove assembly 2.

[0034] In other embodiments, the driven assembly 9 includes a driven rack 91, a driven connecting rod 92, and a curved plate 93; the driven rack 91 is slidably connected to the rotating plate 15 and is connected to the curved plate 93 via the driven connecting rod 92. The driven rack 91 is meshed with the transmission gear 83, and the pushing assembly 5 can drive the driven rack 91 to slide by pushing the curved plate 93. It should be understood that by providing the curved plate 93, the rotating plate 15 does not interfere with the pushing assembly 5 during rotation, thereby preventing the driven assembly 9 from being squeezed by the pushing assembly 5 and displacing during rotation of the rotating plate 15, thereby causing the limiter 3 to displace. It should also be noted that when the concave groove plates 31 abut each other, the curved plates 93 on both sides still maintain a distance from the inner side surface of the concave groove plates 31.

[0035] In other embodiments, the push assembly 5 includes a push slide 51, a push rod 52, a positioning link 53, a positioning rod 54, and a push link 55. The mounting frame 1 is provided with a second slide groove 11, the push slide 51 is slidably connected to the second slide groove 11, the positioning link 53 is fixed to the push slide 51, and the positioning rod 54 is slidably connected to the positioning link 53 and can be inserted into the positioning hole 12. The push rod 52 is fixed to the push slide 51 and can push the curved plate 93 to move. The push slide 51 is connected to the concave slide groove via the push link 55. It should be understood that the end of the push rod 52 is spherical, which can maintain a good abutment state with the curved plate 93 during rotation.

[0036] In other embodiments, a connecting plate 131 is further provided, and the limit frame 13 is slidably mounted on the mounting frame 1 and connected to the driven rack 91 via the connecting plate 131. Since arcuate grooves are often provided on both sides of the brake pad and are centrally symmetrical, while linear grooves are often provided in the center, the limit frame 13 is connected to the driven rack 91, so that the position of the limit frame 13 can be changed according to different groove states.

[0037] In other embodiments, the slotting assembly 2 includes a slider 21, a slotting motor 22, a slotting blade 23, and a limiting rod 24. The slider 21 is slidably connected to the first slide slot 151. The slotting motor 22 is fixed to the bottom of the slider 21, and the slotting blade 23 is coaxially fixed to the output shaft of the slotting motor 22. The limiting rod 24 is fixed to the top of the slider 21, and the two concave slot plates 31 can abut the limiting rod 24. It should be understood that when the two concave slot plates 31 abut, the limiting rod 24 just abuts the inner side surfaces of the two concave slot plates 31.

[0038] The use process of the device of the present application is as follows: in the initial state, the two concave groove plates 31 are away from the limiting rod 24, and the two limiting members 3 simultaneously abut the slider 21 to clamp the slider 21. Moreover, due to the engagement between the limiting members and the driving gear 63, under the action of the worm gear 64 and the worm 72 mechanism, the limiting members 3 will continue to remain in the clamped state and perform arc-shaped slotting as the rotating plate 15 rotates; When linear grooving is required, the two pushing slide bars 51 are brought close to each other and the positioning rod 54 is inserted into the positioning hole 12 to limit the movement of the pushing slide bar 51. During the movement of the pushing slide bar 51, the pushing rod 52 pushes the arc plate 93 toward the limiting rod 24, so that the driven rack 91 slides toward the limiting rod 24, and then drives the worm 72 to rotate through the transmission assembly 8, so that the worm gear 64 rotates and drives the two limiting members 3 away from the slider 21. The slider 21 without restriction can slide in the first slide groove 151, and the limiting rod 24 at the top of the slider 21 is restricted by the two concave groove plates 31 and can only slide along the groove inside the concave groove plate 31. Therefore, at this time, when the rotating plate 15 rotates, the sliding block slides left and right in the first slide groove 151, and its top is interfered by the concave groove plate 31 and moves back and forth in a straight line, and the movement of the slotting knife 23 is forward and backward; When it is necessary to switch to arc grooving again, the positioning of the positioning rod 54 on the push slide 51 is released, and the driven rack 91 is pulled outward, so that the worm gear 64 drives the limit member 3 to clamp the slider 21 again, thereby realizing arc grooving.

[0039] The above-mentioned automobile brake pad grooving device can switch between two modes of straight grooving and arc grooving according to needs.

It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make some simple deductions or substitutions without departing from the concept of the present invention.
