Description

Technical Field

[0001] This application relates to the field of crimping devices, and more particularly to a crimping device for a plate feeder support wheel bearing. Background Technology

[0002] Plate feeders are a type of continuous transport machinery widely used in mining, metallurgy, building materials, ports, coal and chemical industries. When the chain plate in the plate feeder rotates, it uses support wheel bearings. The support wheel bearings consist of a wheel body and a wheel axle. The wheel body and wheel axle need to be assembled by pressing to facilitate the assembly of various parts of the plate feeder.

[0003] In conventional crimping, the axle and wheel body are aligned manually and then connected by applying force to the axle to achieve the crimping. However, during the crimping process, the wheel body is prone to displacement or tilting under the force, making the crimping process cumbersome and inefficient. Summary of the Invention

[0004] To address the issue of wheel displacement or tipping, this application provides a pressing device for the bearings of a plate feeder support wheel.

[0005] The technical solution of the plate feeder support wheel bearing pressing device provided in this application is as follows: A plate feeder support wheel bearing pressing device includes a frame, a limiting plate on the frame, a limiting hole on the limiting plate for inserting a wheel body, and a hydraulic cylinder on the frame located above the limiting plate.

[0006] By adopting the above technical solution, when the wheel axle and wheel body need to be connected, the operator places the wheel body in the limiting hole, which limits the wheel body, and the limiting plate supports the wheel body. Then, one end of the wheel axle is placed in the wheel body, and the hydraulic cylinder is driven so that the piston rod of the hydraulic cylinder pushes the wheel axle into the wheel body. This reduces the possibility of the wheel body shifting or tipping over, facilitates the installation of the wheel axle and wheel body, and improves the crimping efficiency.

[0007] Preferably, the frame is provided with a feeding assembly, which is used to move the wheel into the limiting hole. The limiting plate and the frame slide relative to each other. The frame is provided with a control assembly for controlling the sliding of the limiting plate.

[0008] By adopting the above technical solution, the operator can move the limit plate through the control component, then move the wheel into the limit hole through the feeding component, and then move the limit plate to a suitable position through the control component, which facilitates the installation of the wheel and axle.

[0009] Preferably, the feeding assembly includes a conveyor frame and an electric push rod. The conveyor frame is mounted on the machine frame and is located above the limiting plate. The conveyor frame has a conveying groove for placing the wheel. The electric push rod is mounted on the bottom of the conveying groove. The bottom of the conveying groove has a conveying hole for the wheel to pass through.

[0010] By adopting the above technical solution, the operator can place multiple wheels in the conveying groove, and then drive the electric push rod. The electric push rod can apply force to the wheels, causing the wheels to move within the conveying groove and fall from the conveying hole into the limiting hole, which facilitates the limiting hole to limit the wheels and facilitates the installation of the wheels and axles.

[0011] Preferably, the conveyor frame has a first sliding rod and a second sliding rod sliding relative to each other, the first sliding rod and the second sliding rod being close to or far from each other, the conveyor frame is provided with a first motor and a first gear, the output shaft of the first motor and the first gear are fixedly connected, the first sliding rod and the second sliding rod are both provided with grooves that mate with the first gear, the first sliding rod is fixedly connected with a first mating rod, the first mating rod is provided with a first inclined surface, the second sliding rod is fixedly connected with a second mating rod, the second mating rod is provided with a second inclined surface, the first mating rod and the second mating rod are both located within the conveying hole and slide, the wheel body is in contact with the first inclined surface and the second inclined surface.

[0012] By adopting the above technical solution, when the wheel slides into the conveying groove and reaches the opening of the conveying hole, the wheel contacts the first inclined surface and the second inclined surface, which can support the wheel. When the wheel needs to fall, the operator can drive the first motor. The output shaft of the first motor can drive the rotation of the first gear. The rotation of the first gear can drive the movement of the first sliding rod and the second sliding rod, thereby driving the movement of the first mating rod and the second mating rod, so that the first mating rod and the second mating rod move away from each other. At this time, the wheel can fall naturally, and the first inclined surface and the second inclined surface can provide movement guidance for the wheel, making it easier for the wheel to fall into the limiting hole and reducing the possibility of wheel deviation.

[0013] Preferably, the control component includes a second motor, a screw, and a sliding block. The second motor is mounted on the frame, and the output shaft of the second motor is fixedly connected to the screw. The sliding block is fixedly connected to the limiting plate. A sliding groove is provided on the frame, and the sliding block slides within the sliding groove. The screw and the sliding block are threadedly connected. A clamping component is provided on the frame for clamping the wheel in the limiting hole.

[0014] By adopting the above technical solution, when it is necessary to move the limiting plate, the operator can drive the second motor. The output shaft of the second motor can drive the screw to rotate. The rotation of the screw can drive the sliding block to move. The sliding groove can limit the movement of the sliding block. The movement of the sliding block can drive the limiting plate to move, which facilitates the limiting plate to drive the wheel to perform processing work.

[0015] Preferably, the clamping assembly includes a first bevel gear, a second bevel gear, a rotating rod, a second gear, a third sliding rod, and a fourth sliding rod. The first bevel gear is fixedly connected to the screw, the second bevel gear is fixedly connected to the rotating rod, the rotating rod is rotatably connected to the frame, the rotating rod is located below the screw, and the length direction of the rotating rod is vertical. The first bevel gear and the second bevel gear mesh, the second gear is connected to the rotating rod, and the third sliding rod and the fourth sliding rod slide relative to the rotating rod. The third sliding rod and the fourth sliding rod are close to or far from each other. The third sliding rod and the fourth sliding rod are each provided with a groove for engaging with the second gear. A third mating rod is fixedly connected to the third sliding rod, and a fourth mating rod is fixedly connected to the fourth sliding rod. The third mating rod and the fourth mating rod clamp the wheel.

[0016] By adopting the above technical solution, when the screw rotates and drives the limiting plate to the processing position, the rotation of the screw can drive the rotation of the first bevel gear. The first bevel gear, through the second bevel gear, can drive the rotation of the rotating rod. The rotation of the rotating rod can drive the rotation of the second gear. The rotation of the second gear can drive the movement of the third sliding rod and the fourth sliding rod, thereby driving the movement of the third mating rod and the fourth mating rod. The third mating rod and the fourth mating rod can clamp the wheel body, reducing the possibility of wheel body deviation and further improving the pressing accuracy of the wheel body.

[0017] Preferably, the second gear, the third sliding rod, and the fourth sliding rod all slide relative to the rotating rod. An auxiliary strip is fixedly connected to the rotating rod. An auxiliary groove is provided on the second gear for the auxiliary strip to be inserted. An auxiliary component is provided on the piston rod of the hydraulic cylinder. The auxiliary component is used to control the sliding of the second gear, the third sliding rod, and the fourth sliding rod.

[0018] By adopting the above technical solution, the auxiliary strip can limit the sliding of the second gear. After the wheel body is pressed, the auxiliary component drives the second gear, the third sliding rod and the fourth sliding rod to slide, thereby removing the pressed wheel body from the limiting hole, which improves the pressing efficiency of the wheel body.

[0019] Preferably, the auxiliary component includes a first auxiliary rod and a second auxiliary rod. The first auxiliary rod is fixedly connected to the piston rod of the hydraulic cylinder, and the second auxiliary rod is fixedly connected to the first auxiliary rod. The second auxiliary rod is located below the second gear, and the second auxiliary rod is connected to the second gear, the third sliding rod, and the fourth sliding rod.

[0020] By adopting the above technical solution, when the piston rod of the hydraulic cylinder moves downward to press the axle into the wheel body, the piston rod of the hydraulic cylinder also drives the first auxiliary rod to move. The movement of the first auxiliary rod can drive the movement of the second auxiliary rod, which in turn drives the movement of the second gear, the third sliding rod, and the fourth sliding rod, so that the third and fourth sliding rods clamp the wheel body, facilitating the pressing of the wheel body. After the wheel body is pressed, the piston rod of the hydraulic cylinder moves upward, which can drive the third and fourth sliding rods to move upward, allowing the pressed wheel body to be removed, thus improving the pressing efficiency of the wheel body.

[0021] Preferably, the second auxiliary rod is fixedly connected with a first connecting block, a second connecting block and a third connecting block, the second gear is provided with a first connecting groove for the first connecting block to slide, the third sliding rod is provided with a second connecting groove for the second connecting block to slide, and the fourth sliding rod is provided with a third connecting groove for the third connecting block to slide.

[0022] By adopting the above technical solution, the first connecting block slides within the first connecting groove, and the first connecting block can limit the movement of the second gear, facilitating the movement of the second gear driven by the second auxiliary rod; the second connecting block slides within the second connecting groove, and the second connecting block can limit the movement of the third sliding rod, facilitating the movement of the third sliding rod driven by the second auxiliary rod; the third connecting block slides within the third connecting groove, and the third connecting block can limit the movement of the fourth sliding rod, facilitating the movement of the fourth sliding rod driven by the second auxiliary rod.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a limiting plate, limiting hole, and hydraulic cylinder, when the wheel axle and wheel body need to be connected, the operator places the wheel body in the limiting hole, which limits the wheel body, and the limiting plate supports the wheel body. Then, one end of the wheel axle is placed in the wheel body, and the hydraulic cylinder is driven so that the piston rod of the hydraulic cylinder pushes the wheel axle into the wheel body. This reduces the possibility of the wheel body shifting or tipping over, facilitates the installation of the wheel axle and wheel body, and improves the crimping efficiency. 2. With the installation of the conveyor frame and electric push rod, the operator can place multiple wheels in the conveyor trough and then drive the electric push rod.

[0033] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0034] This application discloses a pressing device for the bearings of the support wheel of a plate feeder, such as... Figure 1 As shown, the device includes a frame 1, on which a limiting disc 2 slides relatively. The limiting disc 2 has a limiting hole 21 for inserting a wheel. When the wheel is inserted into the limiting hole 21, the wheel's flange abuts against the opening of the limiting hole 21, thus supporting the wheel. A hydraulic cylinder 3 is fixedly installed on the frame 1, located above the limiting disc 2. In actual operation, the operator places one end of the wheel axle into the wheel body and drives the hydraulic cylinder 3. The piston rod of the hydraulic cylinder 3 pushes the wheel axle into the wheel body, achieving the pressing connection between the wheel and the wheel axle.

[0035] like Figure 2 and 3 As shown, a feeding assembly 4 is provided on the frame 1. The feeding assembly 4 includes a conveyor frame 41 and an electric push rod 42. The conveyor frame 41 is fixedly installed on the frame 1 and is located above the limiting plate 2. A conveying groove 411 is opened on the conveyor frame 41. The cross-section of the conveying groove 411 is convex, and multiple wheels are placed in the conveying groove 411. The electric push rod 42 is fixedly installed at the bottom of the conveying groove 411 and can push the multiple wheels to move within the conveying groove 411. A conveying hole 412 is opened at the bottom of the conveying groove 411, through which the wheels pass. When the electric push rod 42 pushes the multiple wheels to move, the wheels can be pushed into the conveying hole 412 and fall naturally from the conveying hole 412.

[0036] like Figure 2 and 3As shown, a first sliding rod 43 and a second sliding rod 44 slide relative to each other on the conveyor frame 41. The first sliding rod 43 and the second sliding rod 44 are close to or far from each other, and both the first sliding rod 43 and the second sliding rod 44 have L-shaped cross-sections. The conveyor frame 41 is equipped with a first motor 45 and a first gear 46. The first motor 45 is fixedly installed on the conveyor frame 41, and the output shaft of the first motor 45 is coaxially and fixedly connected to the first gear 46. The first gear 46 is rotatably connected to the conveyor frame 41. Both the first sliding rod 43 and the second sliding rod 44 have grooves that mate with the first gear 46. A first mating rod 431 is fixedly connected to the first sliding rod 43, and the first mating rod 431 has a first inclined surface 432. A second mating rod 441 is fixedly connected to the second sliding rod 44, and the second mating rod 441 has a second inclined surface 442. Both the first mating rod 431 and the second mating rod 441 slide at the opening of the conveying hole 412. When the electric push rod 42 pushes the wheel to the conveying hole 412, the wheel's flange contacts the first inclined surface 432 and the second inclined surface 442. The first inclined surface 432 and the second inclined surface 442 can support and correct the wheel, and then drive the first motor 45. The output shaft of the first motor 45 can drive the rotation of the first gear 46. The rotation of the first gear 46 can drive the movement of the first sliding rod 43 and the second sliding rod 44, thereby driving the movement of the first mating rod 431 and the second mating rod 441, so that the first mating rod 431 and the second mating rod 441 move away from each other. At this time, the wheel can fall naturally into the limiting hole 21, improving the accuracy of the wheel's fall.

[0037] like Figure 1 and 4 As shown, the frame 1 is equipped with a control assembly 5 for controlling the sliding of the limiting disc 2. The control assembly 5 includes a second motor 51, a screw 52, ​​and a sliding block 53. The second motor 51 is fixedly mounted on the frame 1, and its output shaft is fixedly connected to the screw 52. The sliding block 53 is located below the limiting disc 2 and is fixedly connected to it. The frame 1 has a sliding groove 11 for the sliding block 53 to slide in. The screw 52 is rotatably connected to the groove wall of the sliding groove 11, and the screw 52 and the sliding block 53 are threadedly connected. The operator can drive the second motor 51, causing its output shaft to rotate the screw 52. The rotation of the screw 52 can move the sliding block 53, which in turn moves the limiting disc 2, facilitating the wheel's entry into the limiting hole 21.

[0038] like Figure 5 and 6As shown, the frame 1 is equipped with a clamping assembly 6, which includes a first bevel gear 61, a second bevel gear 62, a rotating rod 63, a second gear 64, a third sliding rod 65, and a fourth sliding rod 66. The first bevel gear 61 is fixedly sleeved on the screw 52, ​​and the second bevel gear 62 is fixedly sleeved on the rotating rod 63. The first bevel gear 61 and the second bevel gear 62 mesh. The rotating rod 63 is rotatably connected to the frame 1 and is located below the screw 52. The length direction of the rotating rod 63 is vertical. The second gear 64 and the rotating rod 63 slide relative to each other in the vertical direction. The third sliding rod 65 and the fourth sliding rod 66 both slide relative to the rotating rod 63, moving closer or further apart. The cross-sections of the third sliding rod 65 and the fourth sliding rod 66 are both L-shaped, and both the third sliding rod 65 and the fourth sliding rod 66 have grooves that mate with the second gear 64. A third mating rod 651 is fixedly connected to the third sliding rod 65, and a fourth mating rod 661 is fixedly connected to the fourth sliding rod 66. Rubber blocks (not shown in the figure) are installed on both the third and fourth mating rods 651 and 661. The third and fourth mating rods 651 and 661 can slide to clamp the wheel body at the retaining edge. When the second motor 51 drives the screw 52 to rotate, causing the limiting disc 2 to return the wheel body to the pressing position, the rotation of the screw 52, ​​through the first and second bevel gears 61 and 62, drives the rotation of the rotating rod 63. The rotation of the rotating rod 63 drives the rotation of the second gear 64, which in turn drives the rotation of the third sliding rod 65 and the fourth sliding rod 66, thus bringing the third mating rod 651 and the fourth mating rod 661 closer together to clamp the wheel body and reduce the possibility of wheel body displacement.

[0039] like Figure 6 , 7As shown in Figure 8, an auxiliary strip 631 is fixedly connected to the rotating rod 63, and an auxiliary groove 641 is provided on the second gear 64. The auxiliary groove 641 allows the auxiliary strip 631 to be inserted, and the auxiliary strip 631 can limit the sliding of the second gear 64, allowing the second gear 64 to slide in the vertical direction. An auxiliary assembly 7 is provided on the piston rod of the hydraulic cylinder 3. The auxiliary assembly 7 includes a first auxiliary rod 71 and a second auxiliary rod 72. The first auxiliary rod 71 has an L-shaped cross-section and is fixedly connected to the piston rod of the hydraulic cylinder 3. The second auxiliary rod 72 has a U-shaped cross-section and is fixedly connected to the first auxiliary rod 71. The second auxiliary rod 72 is located below the second gear 64, the third sliding rod 65, and the fourth sliding rod 66. The second auxiliary rod 72 is fixedly connected to the first connecting block 721, the second connecting block 722 and the third connecting block 723. The second gear 64 is provided with a first connecting groove 642 for the first connecting block 721 to slide. The third sliding rod 65 is provided with a second connecting groove 652 for the second connecting block 722 to slide. The fourth sliding rod 66 is provided with a third connecting groove 662 for the third connecting block 723 to slide. When the piston rod of the hydraulic cylinder 3 moves, it can drive the first auxiliary rod 71 to rise and fall. The movement of the first auxiliary rod 71 can drive the movement of the second auxiliary rod 72. The second auxiliary rod 72 can drive the second gear 64 to rise and fall through the first connecting block 721, and can drive the third sliding rod 65 to rise and fall through the second connecting block 722. The third sliding rod 66 can drive the fourth sliding rod 66 to rise and fall through the third connecting block 723. The third sliding rod 65 can drive the third mating rod 651 to rise and fall, and the fourth sliding rod 66 can drive the fourth mating rod 661 to rise and fall. The third mating rod 651 and the fourth mating rod 661 can remove the pressed wheel from the limiting hole 21, which facilitates the removal of the wheel and improves the pressing efficiency of the wheel.

[0040] The implementation principle of the plate feeder support wheel bearing pressing device in this application is as follows: The operator drives the second motor 51 to move the limiting plate 2 below the conveyor frame 41, placing multiple wheels in the conveying groove 411. The electric push rod 42 pushes the wheels into the conveying hole 412, driving the first motor 45 to move the first mating rod 431 and the second mating rod 441 away from each other, allowing the wheels to fall into the limiting hole 21. Then, the operator drives the second motor 51 again to move the limiting plate 2 back to the pressing position. At this time, the screw 52 can drive the second gear 64 to rotate, causing the third mating rod 651 and the fourth mating rod 661 to move closer to each other. When the piston rod of the hydraulic cylinder 3 applies a downward force to the wheel axle, the piston rod of the hydraulic cylinder 3 drives the second auxiliary... When rod 72 moves downward, the second auxiliary rod 72 can drive the third sliding rod 65 and the fourth sliding rod 66 to move downward, thereby driving the third mating rod 651 and the fourth mating rod 661 to move downward, clamping the wheel body in the limiting hole 21; when the piston rod of the hydraulic cylinder 3 finishes processing and moves upward, it can drive the third mating rod 651 and the fourth mating rod 661 to move upward, taking out the wheel body after pressing. At this time, when the limiting plate 2 is moved below the conveyor frame 41 again by the second motor 51, the third mating rod 651 and the fourth mating rod 661 move away from each other, allowing the wheel body after pressing to fall naturally, realizing automatic feeding and unloading of the wheel body, and improving the pressing work of the wheel body.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
