Description

Technical Field

[0001] This utility model relates to the field of drum brake shoe manufacturing technology, and in particular to a high-temperature resistant drum brake shoe bonding and curing device. Background Technology

[0002] Brake shoes are friction couples in drum brakes. Besides possessing the strength and rigidity required of a component, they should also have the highest possible and most stable coefficient of friction, as well as appropriate wear resistance, heat resistance, heat dissipation, and heat capacity. The brake shoe assembly consists of two parts: a rigid web and an arc-shaped friction lining. Currently, there are two methods for connecting the rigid web and the arc-shaped friction lining: one is to drill holes in both and connect them with rivets; the other is to bond the rigid web and the arc-shaped friction lining together using adhesive. The adhesive method requires the use of fixtures during processing.

[0003] Currently, when bonding rigid web plates to curved friction linings, adhesive is usually applied to the rigid web plate by machine or manually, and then the rigid web plate and curved friction lining are placed on a fixture and pressed together. This method is inconvenient and increases the labor intensity of workers. Utility Model Content

[0004] To solve the above problems, this utility model provides a high-temperature resistant drum brake shoe bonding and curing device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-temperature resistant drum brake shoe bonding and curing device, comprising a frame, a worktable on the top of the frame, a placement seat on one side of the worktable and a sliding seat on the other side, a placement groove on the side of the sliding seat adjacent to the placement seat, a drive motor vertically arranged on the worktable on the side of the placement seat away from the sliding seat, a rocker arm arranged on the output axis of the drive motor, a glue dispensing pipe arranged on the end of the rocker arm away from the drive motor, a plurality of glue dispensing holes vertically spaced on the side of the glue dispensing pipe adjacent to the placement seat, a feeding component for feeding glue into the glue dispensing pipe arranged on the worktable, a fixing component arranged on the sliding seat, and a drive cylinder horizontally arranged on the worktable on the side of the sliding seat away from the placement seat, the piston rod of the drive cylinder being connected to the sliding seat.

[0006] By adopting the above technical solution, a workbench, a placement seat, a sliding seat, a drive motor, a glue dispensing tube, a feeding assembly, and a fixing assembly are set up. The placement seat is used to place the rigid web plate, and the placement slot is used to place the arc-shaped friction lining. The fixing assembly restricts the position of the arc-shaped friction lining. The drive motor drives the rocker arm to swing, which moves the glue dispensing tube. When the glue dispensing tube swings to the area of ​​the rigid web plate that needs to be coated with glue, the feeding assembly feeds glue into the glue dispensing tube, so that the glue is squeezed out from the glue dispensing hole and applied to the area of ​​the rigid web plate that needs to be coated with glue. Then the drive motor drives the glue dispensing tube to reset. The drive cylinder drives the sliding seat to slide, which moves the arc-shaped friction lining. When the arc-shaped friction lining is about to contact the rigid web plate, the fixing assembly releases the fixing of the arc-shaped friction lining, and the drive cylinder continues to push, so that the arc-shaped friction lining and the rigid web plate are bonded and cured. When bonding the rigid web plate and the arc-shaped friction lining, the worker only needs to place the rigid web plate on the placement seat and the arc-shaped friction lining in the placement slot, which is simple and convenient and reduces the labor intensity of the workers.

[0007] Furthermore, the fixing assembly includes a mounting plate disposed on the top of the sliding seat, a fixing rod slidably disposed vertically on the mounting plate, the distance between the fixing rod and the bottom of the placement groove being consistent with the thickness of the arc-shaped friction lining, a baffle plate disposed on the top of the fixing rod, a connecting rod disposed on the top of the baffle plate, vertical rods disposed on both sides of the connecting rod, and a rotating shaft rotatably disposed between the tops of the two vertical rods, a first fixing frame and a second fixing frame respectively disposed on both sides of the worktable, a guide plate disposed between the first fixing frame and the second fixing frame, the rotating shaft contacting the top of the guide plate, a wedge block disposed on the guide plate, and a control block connected to the wedge block disposed on the side of the guide plate adjacent to the placement seat.

[0008] By adopting the above technical solution, an installation plate, a fixed rod, a baffle, a connecting rod, a vertical rod, a rotating shaft, a guide plate, and a wedge block are set up. When placing the arc-shaped friction lining in the placement groove, the vertical rod is first pulled upward, causing the connecting rod, baffle, and fixed rod to rise. Then, the arc-shaped friction lining is placed in the placement groove. Subsequently, the vertical rod is lowered, causing the fixed rod to descend and contact the arc-shaped friction lining, thus securing the arc-shaped friction lining in the placement groove. When the drive cylinder drives the sliding seat to slide, the rotating shaft moves on the guide plate. When the arc-shaped friction lining is about to contact the rigid web, the rotating shaft contacts the wedge block. The wedge block pushes the rotating shaft upward, causing the vertical rod, connecting rod, baffle, and fixed rod to rise, thus separating the fixed rod from the arc-shaped friction lining. Then, the rotating shaft contacts the control block, allowing the fixed rod to maintain its current height.

[0009] Furthermore, a tension spring is fitted onto the rod body of the fixing rod located between the baffle and the mounting plate, with one end of the tension spring connected to the baffle and the other end connected to the mounting plate.

[0010] By adopting the above technical solution, a tension spring is fitted on the rod body located between the baffle and the mounting plate to apply a downward pulling force to the fixed rod.

[0011] Furthermore, a vertical plate is vertically arranged on the sliding seat, a slide rail is arranged on one side of the vertical plate, and a slider is arranged on one of the vertical rods, the slider being slidably connected to the slide rail.

[0012] By adopting the above technical solution, a vertical plate, a slide rail, and a slider are set up. When the rotating shaft contacts the wedge block, it will be subjected to a lateral thrust. The slide rail and slider further ensure the stability of the lifting and lowering of the fixed rod.

[0013] Furthermore, a fixing plate is vertically provided on the mounting plate, and a limiting plate is provided on the top of the fixing plate, with one side of the limiting plate located above the baffle.

[0014] By adopting the above technical solution, a fixed plate and a limiting plate are set, and the limiting plate restricts the upward distance of the fixed rod.

[0015] Furthermore, the worktable has two spaced-apart strip holes, the bottom of the sliding seat is provided with a sliding column, the sliding column is slidably connected to the strip holes, and the bottom of the sliding column is provided with a baffle, the baffle is in slidable contact with the bottom of the worktable.

[0016] By adopting the above technical solution, a strip hole, a sliding column, and a baffle are set. The sliding column slides within the strip hole to ensure the stability of the sliding seat. The baffle slides in contact with the bottom of the worktable to restrict the position of the sliding column, further ensuring the stability of the sliding seat.

[0017] Furthermore, the feeding assembly includes a receiving box and a feeding pump set on the workbench. The bottom of the receiving box is provided with a discharge port. The feed pipe of the feeding pump is connected to the discharge port, and the discharge pipe is connected to a feeding pipe. The feeding pipe is connected to the glue dispensing pipe.

[0018] By adopting the above technical solution, a receiving box, a feeding pump, and a dispensing pipe are set up. The receiving box is used to store glue, and the feeding pump pumps the glue in the receiving box into the feeding pipe, and then into the dispensing pipe.

[0019] In summary, this utility model has the following beneficial effects: It includes a worktable, a placement seat, a sliding seat, a drive motor, a glue dispensing tube, a feeding assembly, and a fixing assembly. The placement seat is used to place the rigid web plate, the placement groove is used to place the arc-shaped friction lining, and the fixing assembly restricts the position of the arc-shaped friction lining. The drive motor drives a rocker arm to swing, moving the glue dispensing tube. When the glue dispensing tube swings to the area of ​​the rigid web plate where glue needs to be applied, the feeding assembly feeds glue into the glue dispensing tube, causing the glue to be squeezed out from the dispensing hole and applied to the area of ​​the rigid web plate where glue is needed. The area where the glue is applied is then driven by a motor to reset the glue tube; the drive cylinder drives the sliding seat to slide, moving the arc-shaped friction lining. When the arc-shaped friction lining is about to contact the rigid web, the fixing component releases the arc-shaped friction lining, and the drive cylinder continues to push, so that the arc-shaped friction lining and the rigid web are bonded and cured; when bonding the rigid web and the arc-shaped friction lining, the worker only needs to place the rigid web on the placement seat and the arc-shaped friction lining in the placement groove, which is simple and convenient and reduces the labor intensity of the workers.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-4 As shown in the figure, this application discloses a high-temperature resistant drum brake shoe bonding and curing device, including a frame 10, a worktable 11, a placement seat 20, a sliding seat 30, a drive motor 40, a feeding assembly 50, and a fixing assembly 60. The worktable 11 is located on the top of the frame 10, and the placement seat 20 is located on one side of the worktable 11. The placement seat 20 is used to place a rigid web plate. The placement seat 20 has several fixing posts, which correspond to openings on the rigid web plate. The openings on the rigid web plate are aligned with the corresponding fixing posts, and then the rigid web plate is placed on the placement seat 20. The fixing posts pass through the openings to ensure the accurate positioning of the rigid web plate. The sliding seat 30 is slidably disposed on the other side of the worktable 11, and the placement seat 20 is in the sliding direction of the sliding seat 30. A placement groove 31 is provided on the side of the sliding seat 30 adjacent to the placement seat 20 for placing an arc-shaped friction lining. A drive motor 40 is vertically mounted on the worktable 11, located on the side of the placement seat 20 away from the sliding seat 30. A rocker arm 41 is mounted on the output axis of the drive motor 40. A glue dispensing tube 42 is located at the end of the rocker arm 41 away from the drive motor 40. Both ends of the glue dispensing tube 42 are closed. Several glue dispensing holes are vertically spaced along the side of the glue dispensing tube 42 adjacent to the placement seat 20. A feeding assembly 50 is mounted on the worktable 11 and is used to feed glue into the glue dispensing tube 42. The drive motor 40 drives the rocker arm 41 to swing, causing the glue dispensing tube 42 to move. When the glue dispensing tube 42 moves, there is a small gap between the glue dispensing tube 42 and the surface of the rigid web. When the glue dispensing tube 42 swings to the area of ​​the rigid web where glue needs to be applied, the feeding assembly 50 feeds glue into the glue dispensing tube 42, causing the glue to be squeezed out from the glue dispensing holes and applied to the area of ​​the rigid web where glue needs to be applied. A drive cylinder 70 is horizontally mounted on the workbench 11 on the side of the sliding seat 30 away from the placement seat 20. The piston rod of the drive cylinder 70 is connected to the sliding seat 30. The drive cylinder 70 drives the sliding seat 30 to slide, which in turn moves the arc-shaped friction lining, causing the arc-shaped friction lining to bond and solidify with the rigid web. When bonding the rigid web to the arc-shaped friction lining, the operator only needs to place the rigid web on the placement seat 20 and the arc-shaped friction lining in the placement groove 31, which is simple and convenient and reduces the labor intensity of the operator.

[0027] Specifically, the workbench 11 has two spaced-apart slots 12. A sliding column 37 is provided at the bottom of the sliding seat 30, and the sliding column 37 is slidably connected to the slots 12. The sliding column 37 slides within the slots 12, ensuring the stability of the sliding seat 30. A baffle 38 is provided at the bottom of the sliding column 37, and the baffle 38 slides in contact with the bottom of the workbench 11, restricting the position of the sliding column 37 and further ensuring the stability of the sliding seat 30. The feeding assembly 50 includes a receiving box 51 and a feeding pump 52 provided on the workbench 11. The receiving box 51 has a discharge port at its bottom. The inlet pipe of the feeding pump 52 is connected to the discharge port, and the discharge pipe is connected to a feeding pipe 53. The feeding pipe 53 is a flexible hose and is connected to the glue outlet pipe 42. The receiving box 51 is used to store glue, and the feeding pump 52 pumps the glue from the receiving box 51 into the feeding pipe 53, which then enters the glue outlet pipe 42.

[0028] During setup, a fixing component 60 is provided on the sliding seat 30. The fixing component 60 includes a mounting plate 61 horizontally positioned on the top of the sliding seat 30. A fixing rod 62 is vertically slidably mounted on the mounting plate 61. The distance between the fixing rod 62 and the bottom of the placement groove 31 is consistent with the thickness of the arc-shaped friction lining. When placing the arc-shaped friction lining into the placement groove 31, the fixing rod 62 is first moved upward, and then the arc-shaped friction lining is placed into the placement groove 31. Subsequently, the fixing rod 62 is lowered so that it contacts the arc-shaped friction lining, thus securing the arc-shaped friction lining into the placement groove 31. A baffle 63 is provided at the top of the fixing rod 62. A tension spring 69 is sleeved on the rod body of the fixing rod 62 located between the baffle 63 and the mounting plate 61. One end of the tension spring 69 is connected to the baffle 63, and the other end is connected to the mounting plate 61. A connecting rod 631 is horizontally arranged at the top of the baffle 63, and vertical rods 632 are arranged at the top of both sides of the connecting rod 631. A rotating shaft 633 is rotatably arranged between the tops of the two vertical rods 632. A first fixed frame 64 and a second fixed frame 65 are respectively arranged on both sides of the worktable 11. A guide plate 66 is horizontally arranged between the first fixed frame 64 and the second fixed frame 65. The rotating shaft 633 contacts the top of the guide plate 66. A wedge block 67 is arranged on the guide plate 66. A control block 68 connected to the wedge block 67 is arranged on the side of the guide plate 66 adjacent to the placement seat 20. The inclined surface of the wedge block 67 is adjacent to the driving air. One side of cylinder 70 contacts the surface of guide plate 66, and the side away from drive cylinder 70 contacts the top surface of control block 68. When drive cylinder 70 drives sliding seat 30 to slide, rotating shaft 633 moves on guide plate 66. When arc-shaped friction lining is about to contact rigid web, rotating shaft 633 contacts wedge block 67. Wedge block 67 pushes rotating shaft 633 upward, causing vertical rod 632, connecting rod 631, baffle 63, and fixed rod 62 to rise, so that fixed rod 62 separates from arc-shaped friction lining. Then rotating shaft 633 contacts control block 68, so that fixed rod 62 maintains the current height.

[0029] In the specific configuration, a vertical plate 32 is vertically mounted on the sliding seat 30, and a slide rail 33 is mounted on one side of the vertical plate 32. A slider 34 is mounted on one of the vertical rods 632, and the slider 34 is slidably connected to the slide rail 33. When the rotating shaft 633 contacts the wedge block 67, it will be subjected to a lateral thrust. The slide rail 33 and the slider 34 further ensure the stability of the lifting and lowering of the fixed rod 62. A fixed plate 35 is vertically mounted on the mounting plate 61, and a limit plate 36 is mounted on the top of the fixed plate 35. One side of the limit plate 36 is located above the baffle 38, and the limit plate 36 limits the rising distance of the fixed rod 62.

[0030] The working principle of the high-temperature resistant drum brake shoe bonding and curing device in this embodiment is as follows: the rigid web is placed on the placement seat 20, the fixing rod 62 is pulled up, and the arc-shaped friction lining is placed in the placement groove 31. Then, the drive motor 40 is started to drive the rocker arm 41 to swing, which drives the glue dispensing tube 42 to move. When the glue dispensing tube 42 swings to the area of ​​the rigid web that needs to be coated with glue, the feed pump 52 pumps the glue in the receiving box 51 into the feed pipe 53, and then into the glue dispensing tube 42, so that the glue is squeezed out from the glue dispensing hole and applied to the area of ​​the rigid web that needs to be coated with glue. Then, the drive motor 40 drives the glue dispensing tube 42 to reset. Re-start the drive cylinder 70 to drive the sliding seat 30 to slide, causing the arc-shaped friction lining to move. The rotating shaft 633 moves on the guide plate 66, and then the rotating shaft 633 contacts the wedge block 67. The wedge block 67 pushes the rotating shaft 633 upward, causing the vertical rod 632, connecting rod 631, baffle 63, and fixing rod 62 to rise, so that the fixing rod 62 separates from the arc-shaped friction lining. Then the rotating shaft 633 contacts the control block 68, so that the fixing rod 62 maintains the current height. The drive cylinder 70 continues to push, so that the arc-shaped friction lining and the rigid web are bonded and cured.
