Description

Technical Field

[0001] The invention belongs to the technical field of friction plate bonding, and in particular relates to a friction plate bonding auxiliary tooling and a clamping device. Background Art

[0002] Drum friction pads typically consist of a shoe and a friction facing, with the facing typically being glued to the brake housing. After the shoe and facing are bonded together with adhesive, they are then heated inside a tunnel furnace to dry the adhesive and complete the bonding process. However, during the current production process, the adhesive between the shoe and the friction facing is not completely dry. This can lead to relative displacement during transportation, resulting in misalignment after exiting the tunnel furnace. In severe cases, this can result in product failure. Summary of the Invention

[0003] The embodiment of the present invention provides a friction plate bonding auxiliary tooling and clamping device, which aims to solve the problem in the prior art that when drum-type friction plates are bonded and dried, the horseshoe and the friction surface plate are easily misaligned, affecting product quality.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a friction plate bonding auxiliary tooling and clamping device, comprising:

[0005] There are two mounting frames, and the two mounting frames are provided with slots for mounting horseshoes on opposite sides thereof;

[0008] The annular ring is sleeved on the outer sides of the two mounting frames, and the horseshoe and the friction surface are located between the annular ring and the mounting frames.

[0009] Compared to the prior art, the solution shown in the embodiments of the present application utilizes two opposing mounting frames, with an external spring positioned between them to propel the two mounting frames away from each other. The mounting frames are provided with retaining grooves for accommodating the ribs on the horseshoe. Annular rings are also mounted on the outsides of the two mounting frames to secure the friction plate to the mounting frames. Removable retaining members are also mounted on the mounting frames to secure the friction plate to the mounting frames, ensuring the relative position of the horseshoe and the friction plate along the width of the friction plate. During use, the two bonded friction plates are mounted on the two mounting frames, followed by retaining members mounted on the corresponding friction plates. The retaining members further position the horseshoe and the friction plate relative to each other. Finally, the relative position between the two mounting frames is reduced, and the annular rings are fitted onto the outsides of the two mounting frames. The retaining member between the two mounting frames is released, and the external spring members press the two mounting frames against the inner wall of the annular ring, securing the friction plate within the annular ring. During the tunnel oven drying process, the stability of the relative position between the shoe and the friction surface is ensured, effectively improving the product qualification rate.

[0010] In combination with the first aspect, an embodiment of the present invention further provides a friction plate bonding auxiliary fixture clamping device, comprising:

[0011] turntable;

[0012] There are two spreading rods, which are relatively slidably arranged on the turntable;

[0013] The pushing assembly is installed between the rotating disk and the two spreading rods, and is used for driving the two spreading rods to move relative to each other.

[0014] In a possible implementation, the pushing component includes:

[0015] A pushing member, a fixed end of which is fixedly mounted on the turntable;

[0016] There are two connecting rods, one end of each of the two connecting rods is hingedly set on the two spreading rods, and the other end of each of the two connecting rods is hingedly set on the driving end of the pushing member.

[0020] A loading assembly is mounted on the support arm and is used to push and fix the clamping component onto the friction surface.

[0021] In a possible implementation, the loading assembly includes:

[0022] A material storage trough is provided along the length direction of the support arm, and a notch is provided at one end of the material storage trough for preventing the clamping member from sliding out of the material storage trough;

[0026] A push rod is slidably arranged on the side wall of the material storage trough, and the push rod extends into the interior of the material storage trough;

[0027] An elastic member is installed between the side wall of the material storage trough and the pushing rod, and is used to push the pushing rod to move toward the direction close to the clearance gap.

[0031] In a possible implementation, there are two support arms, which are hingedly disposed on both sides of the turntable, and are used to simultaneously abut against friction surfaces on two mounting frames.

[0032] Compared to the prior art, the solution shown in the embodiments of the present application utilizes a turntable with two spreading rods slidably mounted on the turntable. The two spreading rods slide relative to each other in a straight line. The turntable also includes a push assembly for pushing the two spreading rods toward each other or toward each other. During use, the auxiliary tooling can be placed on the turntable with the two spreading rods positioned outside of the two mounting brackets. When installing the friction plate, the push assembly can be used to push the two spreading rods toward each other, thereby reducing the distance between the two clamping parts. The friction plate and clamping parts can then be installed on the mounting brackets. Once the friction plate is in place, an annular ring is fitted onto the outside of the two mounting brackets. Finally, the push assembly is released, and the two mounting brackets, acting under the force of the external spring, move outward and tighten within the annular ring.

DETAILED DESCRIPTION

[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] Please also refer to Figures 1 to 6 The friction plate bonding auxiliary tooling provided by the present invention will now be described. The friction plate bonding auxiliary tooling comprises a mounting frame 1, an external spring 2, a clamping member 3, and an annular ring 4. There are two mounting frames 1, each with a slot for clamping the horseshoe on its opposite sides. The external spring 2 is mounted between the two mounting frames 1 and is used to push the two mounting frames 1 in a relatively separate direction. There are multiple clamping members 3, each with a bent end having a limit plate for clamping onto the two sides of the friction surface. The annular ring 4 is mounted on the outside of the two mounting frames 1, with the horseshoe and friction surface located between the annular ring 4 and the mounting frames 1.

[0043] Compared to the prior art, the friction plate bonding auxiliary tooling provided in this embodiment features two opposing mounting frames 1, with an external spring 2 positioned between them to propel the two mounting frames 1 away from each other. Each mounting frame 1 is provided with a retaining groove for accommodating the ribs on the horseshoe. An annular ring 4 is also mounted on the outside of each mounting frame 1, securing the friction plate to the mounting frames 1. Furthermore, a removable retaining member 3 is attached to the mounting frame 1, securing the friction plate to the mounting frame 1. This retaining member 3 ensures the relative position of the horseshoe and the friction plate along the width of the friction plate. In the present application, when in use, the two bonded friction plates are respectively mounted on the two mounting brackets 1, and then the clamping plates are mounted on the corresponding friction plates. The clamping plates can further locate the relative position of the horseshoe and the friction surface plate. Finally, the relative position between the two mounting brackets 1 is reduced, and the annular ring 4 is fitted onto the outside of the two mounting brackets 1. The limit between the two mounting brackets 1 is loosened, and the two mounting brackets 1 can be pressed against the inner wall of the annular ring 4 through the external elastic member 2, so that the friction plate can be fixed inside the annular ring 4. During the tunnel oven drying process, the stability of the relative position of the horseshoe and the friction surface plate is ensured, effectively improving the qualified rate of the product.

[0044] Specifically, in this embodiment, the mounting frame 1 includes two wing plates arranged at an angle, with slots located on the wing plates. A connecting plate is connected to the ends of the two wing plates with the smallest spacing between them. The connecting plate and the wing plates are an integral, bent, and formed structure. During use, the propeller rod 6 rests against the connecting plate, the ribs on the horseshoe fit within the slots on the two wing plates, and the inner arc of the curved plate on the horseshoe rests against the ends of the wing plates. The external spring 2 squeezes the friction plate between the annular ring 4 and the mounting frame 1. Furthermore, the arrangement of the annular ring 4 and the mounting frame 1 allows two friction plates to be installed simultaneously on the auxiliary tooling, improving production efficiency.

[0045] Preferably, in this embodiment, the friction plate is squeezed between the mounting frame 1 and the annular ring 4, which can increase the bonding force between the friction plate and the horseshoe, and improve the bonding effect between the friction plate and the horseshoe in the later stage.

[0046] Specifically, in this embodiment, a guide post and a guide sleeve are fixedly mounted on each of the two mounting frames 1. The guide post is slidably disposed within the guide sleeve. The elastic member 832 is a spring, the ends of which are fixedly mounted on each of the two mounting frames 1, and the elastic member 832 is sleeved onto the outside of the guide post and the guide sleeve.

[0047] Based on the same inventive concept, the present application also provides a friction plate bonding auxiliary fixture clamping device, please refer to Figures 1 to 6 The friction plate bonding auxiliary fixture clamping device provided by the present invention is now described. The friction plate bonding auxiliary fixture clamping device comprises a turntable 5, a spreading rod 6, and a push assembly 7. Two spreading rods 6 are provided on the turntable 5 for relative sliding movement. The push assembly 7 is mounted between the turntable 5 and the two spreading rods 6 to drive the two spreading rods 6 relative to each other.

[0048] The friction plate bonding auxiliary fixture clamping device provided in this embodiment is used to clamp the friction plate to the bonding auxiliary fixture. Compared to the prior art, it comprises a turntable 5 on which two spreading rods 6 are slidably mounted. The two spreading rods 6 are arranged to slide relative to each other in a straight line. The turntable 5 is also provided with a pushing assembly 7 for pushing the two spreading rods 6 toward each other or toward each other. During use, the auxiliary fixture can be placed on the turntable 5, with the two spreading rods 6 positioned outside of the two mounting frames 1. When installing the friction plate, the pushing assembly 7 can be used to push the two spreading rods 6 toward each other, thereby reducing the distance between the two clamping members 3. The friction plate and clamping members 3 can then be installed on the mounting frames 1. Once the friction plate is in place, the annular ring 4 is then fitted onto the outside of the two mounting frames 1. Finally, the pushing assembly 7 is released. The two mounting frames 1 are then moved outward by the force of the external elastic member 2 and tightened within the annular ring 4. This completes the installation of the friction plate to the auxiliary fixture, making the operation convenient and reducing operator labor.

[0049] Specifically, in this embodiment, the spreading rod 6 is arranged in the vertical direction, a sliding block is fixedly installed at the bottom of the spreading rod 6, and a slide groove for accommodating the sliding of the sliding block is provided on the turntable 5. The sliding blocks corresponding to the two mounting frames 1 are slidably arranged inside the slide groove. During operation, the two spreading rods 6 respectively abut against the outer surfaces of the connecting plates on the two mounting frames 1, and the two mounting frames 1 are retracted in a relatively close direction by pushing the assembly 7, so that the outer elastic member 2 is tightened and the distance between the two mounting frames 1 is reduced. This makes it convenient to fit the annular ring 4 between the two mounting frames 1, and finally, push the two spreading rods 6 to move in a relatively distant direction. The two mounting frames 1 are tightened to the inner wall of the annular ring 4 under the push of the outer elastic member 2. Compared with manual loading, the operation is more convenient and quick, which reduces the labor of the operator.

[0050] In some embodiments, the pushing component 7 can be used as follows Figure 2 、 Figure 3 See also Figure 2 、 Figure 3 The pushing assembly 7 comprises a pushing member 71 and a connecting rod 72. The fixed end of the pushing member 71 is fixedly mounted on the turntable 5. There are two connecting rods 72, one end of each connecting rod 72 being hingedly mounted on the two spreading rods 6, and the other end of each connecting rod 72 being hingedly mounted on the driving end of the pushing member 71. The pushing member 71 is a hydraulic cylinder mounted below the turntable 5, and the driving end of the pushing member 71 moves horizontally. This saves space on site for the entire equipment.

[0051] Specifically, in this embodiment, a connecting block is fixedly installed at the driving end of the pushing member 71, one end of the two connecting rods 72 is respectively hinged on the connecting block, and the other ends of the two connecting rods 72 are respectively hinged on the two sliding blocks, so that the two support rods 6 can be synchronously driven relatively closer or relatively farther away by the pushing member 71.

[0052] In some embodiments, the turntable 5 may be configured as follows: Figure 2 The structure shown. Figure 2The friction plate bonding auxiliary tooling clamping device also includes a fixed seat, a support arm 8 and a loading assembly. The turntable 5 is rotatably set on the fixed seat; the support arm 8 is hingedly set on the fixed seat, and the support arm 8 can abut against the outside of the friction surface; the loading assembly is installed on the support arm 8, and is used to push the clamping part 3 to be fixed on the friction surface. The turntable 5 is rotatably set on the fixed seat, and the pushing assembly 7 is rotatably set on the fixed seat along with the turntable 5. When in use, the clothing tooling can be placed on the turntable 5, and the pushing assembly 7 is started so that the two mounting frames 1 on the auxiliary tooling are clamped between the two support rods 6, thereby completing the fixation of the auxiliary tooling on the turntable 5. The friction plate is then limited on the mounting frame 1 by the support arm 8 to ensure the stability of the position of the friction plate on the mounting frame 1.

[0053] Specifically, in this embodiment, by designing the turntable 5 on the fixed seat, and the turntable 5 can be rotated on the fixed seat, it is convenient for the operator to freely adjust the angle of the auxiliary tooling, thereby adjusting the position of the friction plate. When installing the clamping part 3, the operator can complete the installation of the clamping part 3 on the two mounting frames 1 on one side.

[0054] Specifically, in this embodiment, after the fixture 3 is installed on a single mounting bracket 1, the support arm 8 can be pushed to swing outward to disengage the friction plate, and the turntable 5 can be started to rotate. When another mounting bracket 1 is moved to the installation position, the support arm 8 abuts against the outer side of the friction surface plate to adjust the position of the friction plate on the mounting bracket 1, and the fixture 3 is installed. Each time the turntable 5 is adjusted, the support arm 8 further corrects the position of the friction plate on the mounting bracket 1, thereby ensuring the smooth progress of subsequent operations.

[0055] Preferably, in this embodiment, the support arm 8 is further provided with a loading assembly for pushing the fixture 3 onto the friction surface. The provision of the pushing assembly 7 enables automatic installation of the fixture 3. During operation, when the support arm 8 abuts the outer side of the friction surface, the loading assembly can be activated to attach the fixture 3 to the friction surface. After a single fixture 3 is installed, the turntable 5 is activated, and then the pushing assembly 7 is activated again at the appropriate position to continue installing the fixture 3 at the remaining locations on the friction surface. During the rotation of the turntable 5, the support arm 8 can remain in contact with the outer side of the friction surface to ensure the stability of the friction surface during installation. This ensures that the fixture 3 can be stably installed on the friction surface.

[0056] In some embodiments, the above-mentioned feeding assembly can be used as follows Figure 2 、 Figure 4 and Figure 5 See also Figure 2 、 Figure 4 and Figure 5The loading assembly includes a trough 81, a push plate 82, and a pushing assembly 83. The trough 81 is arranged along the length of the support arm 8. A clearance notch is provided at one end of the trough 81 to prevent the card component 3 from sliding out of the trough 81. The push plate 82 is slidably arranged in the clearance notch to push the card component 3 onto the friction surface. The pushing assembly 83 is installed inside the trough 81 to push the card component 3 into the clearance notch. The trough 81 is located on the support arm 8. The end of the trough 81 with the clearance notch serves as the end of the support arm 8 that abuts the friction surface. The width of the trough 81 is adapted to the length of the card component 3, allowing the card component 3 to slide inside the trough 81. When the card component 3 slides into the clearance notch, the card component 3 is pressed against the inner wall of the clearance notch by the force of the pushing assembly 83. Under the action of the push plate 82, the card assembly 3 can be pushed out from the gap and clamped to the outside of the friction plate to achieve the installation of the card assembly 3. The operation is convenient, the installation of the card assembly 3 can be completed automatically, and multiple card assembly 3 can be installed on the friction plate in sequence.

[0057] Specifically, in this embodiment, during operation, multiple card components 3 can be placed in sequence inside the storage trough 81, and the opening of the card component 3 is located on the side of the storage trough 81 where a clearance gap is provided. The multiple card components 3 can be pushed toward the clearance gap by the pushing component 83, and the multiple card components 3 are squeezed inside the storage trough 81. This enables the installation of multiple card components 3. When a single card component 3 is pushed out, the card components 3 at the rear are moved to the clearance gap in sequence by the pushing component 83. The operation of loading the card components 3 once and installing them multiple times can be achieved. This reduces the workload of the operator and makes the operation simpler and more convenient.

[0058] Specifically, in this embodiment, a cylinder for pushing the pushing plate 82 to move is installed on the supporting arm 8 .

[0059] In some embodiments, the pushing component 83 may be configured as follows: Figure 4 、 Figure 5 See also Figure 4 、 Figure 5The pushing assembly 83 includes a push rod 831 and an elastic member 832. The push rod 831 is slidably mounted on the side wall of the storage trough 81 and extends into the interior of the storage trough 81. The elastic member 832 is installed between the side wall of the storage trough 81 and the push rod 831 and is used to push the push rod 831 toward the clearance gap. An elongated clearance hole for accommodating the push rod 831 is provided on the side wall of the storage trough 81 on the side where the clearance gap is provided. The push rod 831 is slidably mounted within the elongated clearance hole and extends into the storage trough 81. The push rod 831 is used to abut against one side of the outermost clamping component 3. The elastic member 832 is a spring that pushes the push rod 831 toward the clearance gap. This allows the subsequent clamping component 3 to automatically move into the clearance gap after a single clamping component 3 is removed from the clearance gap.

[0060] In some embodiments, the extrusion assembly may be configured as follows: Figure 4 、 Figure 5 See also Figure 4 、 Figure 5 A support plate 833 is mounted on the side wall of the trough 81. The position of the support plate 833 on the side wall of the trough 81 is adjustable along the length of the trough 81. The push rod 831 is slidably mounted on the support plate 833, and one end of the elastic member 832 abuts against the support plate 833. A support plate 833 is mounted on the outer wall of the trough 81. A screw that penetrates the side wall of the trough 81 is fixedly mounted on the support plate 833. An elongated hole is provided in the side wall of the trough 81 to accommodate the screw. The length of the elongated hole runs along the length of the trough 81. A tightening nut is also threadedly connected to the screw rod, and the tightening nut is used to rest against the inner wall of the storage trough 81 to fix the support plate 833 to the storage trough 81. When the position of the support plate 833 needs to be adjusted, the position of the support plate 833 can be adjusted by loosening the tightening nut. After the adjustment is completed, the screw rod is fixed to the side wall of the storage trough 81 by tightening the nut.

[0061] Specifically, in this embodiment, the push rod 831 includes a stopper rod extending into the interior of the material storage trough 81 and a guide rod slidably arranged on the support plate 833, and the stopper rod and the guide rod are arranged perpendicular to each other. The elastic member 832 is sleeved on the outside of the guide rod, and the two ends of the elastic member 832 respectively abut against the support plate 833 and the stopper rod. During use, the position of the support plate 833 can be adjusted according to the number of the card components 3 inside the material storage trough 81. During use, as the number of the card components 3 inside the material storage trough 81 gradually decreases, the support plate 833 is adjusted to move toward the direction of the clearance gap, thereby increasing the force of the elastic member 832 on the stopper rod, thereby ensuring the stability of the card components 3 during movement.

[0062] Preferably, in this embodiment, a baffle is provided on the side wall at the top of the material storage trough 81, which is bent obliquely downward to prevent the card component 3 from sliding out of the material storage trough 81. When the card component 3 is installed inside the material storage trough 81, the card component 3 is slid between the inner wall of the material storage trough 81 and the baffle, thereby ensuring the stability of the card component 3 during its movement inside the material storage trough 81.

[0063] In some embodiments, the turntable 5 may be configured as follows: Figure 2 、 Figure 6 See also Figure 2 、 Figure 6 A worm wheel 51 is fixedly mounted on the outside of the turntable 5, and a worm 52 is rotatably mounted on the fixed seat and is meshed with the worm wheel 51. A rotating ring is fixedly mounted on the bottom end of the turntable 5 and is rotatably mounted on the fixed seat. The rotating ring is rotatably mounted on the fixed seat via a bearing. A worm wheel 51 is also fixedly mounted on the outside of the turntable 5, and a worm 52 is rotatably mounted on the fixed seat. The worm 52 is meshed with the worm wheel 51. A motor is also fixedly mounted on the fixed seat. The motor is used to drive the worm 52 to rotate, so that the rotation angle of the turntable 5 can be adjusted. When installing the clamping component 3, the worm wheel 51 can be driven to rotate a certain angle by the worm wheel 51, and then the clamping component 3 can be installed on the friction plate in sequence in combination with the loading assembly.

[0064] Specifically, in this embodiment, the installation position and the number of the clamping parts 3 can be freely adjusted according to the length of the friction plate through the rotation of the turntable 5 combined with the feeding assembly.

[0065] In some embodiments, the support arm 8 may be configured as follows: Figure 2 、 Figure 4 See also Figure 2 、 Figure 4 The support arm 8 is rotatably provided with a support roller 84 for contacting the outer side of the friction plate. A pusher 85 is hingedly provided on the fixed base to propel the support arm 8 toward the friction plate. One end of the support arm 8 is hingedly provided on the fixed base, while the other end of the support arm 8 extends toward the turntable 5. When placing or removing the auxiliary tooling onto or from the turntable 5, the pusher 85 drives the support arm 8 to swing away from the turntable 5, thereby leaving sufficient operating space for the operator. Once the friction plate is installed on the mounting frame 1, the pusher 85 drives the support arm 8 toward the turntable 5, allowing the support roller 84 on the support arm 8 to contact the outer side of the friction plate, thereby stabilizing the friction plate on the mounting frame 1. This also maintains a certain distance between the clearance notch in the material storage trough 81 and the friction plate, facilitating the secure installation of the clamping member 3 onto the friction plate.

[0066] Preferably, in this embodiment, a swing arm is hingedly provided on the side of the support arm 8 near the turntable 5. A torsion spring or spring is provided between the support arm 8 and the swing arm to propel the swing arm toward the friction plate. The support roller 84 is rotatably provided on the swing arm. This provides a certain buffering effect on the position of the support roller 84 during the rotation of the turntable 5.

[0067] Specifically, in this embodiment, the pushing member 85 is a buffer cylinder, the fixed end of the pushing member 85 is hingedly arranged on the fixed seat, and the driving end of the pushing member 85 is hingedly arranged at the middle of the support arm 8.

[0068] In some embodiments, the support arm 8 may be configured as follows: Figure 2 The structure shown. Figure 2 Two support arms 8 are hingedly mounted on either side of the turntable 5. These two support arms 8 are used to simultaneously abut against the friction plates on the two mounting brackets 1. The two support arms 8 are mounted on corresponding positions on the two mounting brackets 1. By providing two support arms 8, the clamping members 3 can be simultaneously added to the friction plates on both mounting brackets 1. This prevents the turntable 5 from rotating at large angles and improves the efficiency of installing the clamping members 3.

[0069] Preferably, in this embodiment, a guide plate is bent outwardly on the limit plate of the clamping component 3. The provision of the guide plate can facilitate the installation of the clamping component 3 on the friction plate.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
