Description

Technical Field

[0001] This utility model belongs to the field of tappet processing equipment, and relates to the transfer technology of tappets before cleaning, and in particular to a tappet transfer device. Background Technology

[0002] After machining, the tappets require surface treatment such as carburizing, nitriding, or hard chrome plating. Before this treatment, it is necessary to clean away any residues generated during machining, such as metal shavings and oil, to avoid affecting the surface treatment effect. Before cleaning, the push rods need to be placed sequentially into a receiving frame equipped with a clamping plate. The clamping plate has an upward-facing U-shaped notch. When placing the push rods, the open end should face down at the bottom of the receiving frame, and the closed end should be placed into the U-shaped notch, so that the push rods are placed at an angle, which facilitates the discharge of metal debris during cleaning. If this is done manually, the labor cost is high, and the number of push rods that can be placed at a time is limited to the number that can be held in one hand, which is time-consuming and labor-intensive. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a tappet transfer device that improves automation, has a simple structure, and is highly efficient.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed: A tappet transfer device is disposed above the end of a conveying assembly in the conveying direction, for transferring a tappet conveyed by the conveying assembly into a receiving frame located on one side of the conveying assembly. The device includes: The transfer assembly includes a movable seat that moves along a direction perpendicular to the conveying direction of the conveying assembly. The movable seat has an inverted L-shaped cross-section. The horizontal part of the movable seat is connected to a vertically arranged telescopic rod. The vertical part is formed vertically downward on one side of the horizontal part, and a rotating plate is rotatably provided on the other side of the horizontal part. The locking assembly has two sets, which are vertically installed at both ends of the movable seat. It includes a limiting plate located above the horizontal part. One end of the limiting plate extends out of the other side of the horizontal part to limit the upward rotation of the rotating plate. The other end is connected to a vertical rod that passes through the horizontal part. The lower end of the vertical rod is provided with a push plate. One side of the push plate is provided with an inclined surface. The lower end of the inclined surface corresponds to the bottom surface of the rotating plate. A spring is installed on the vertical rod. One end of the spring abuts against the push plate, and the other end abuts against the horizontal part.

[0005] Furthermore, the upper end of the telescopic rod is slidably connected to a crossbeam, one end of which is located above the end of the conveying assembly in the conveying direction, and the other end is located above the receiving frame.

[0006] The movable base has rectangular holes running vertically through both ends, and the cross-section of the vertical rod is adapted to the rectangular holes.

[0007] The push plate has a right-angled trapezoidal structure, with the lower end of the vertical rod connected to the upper bottom edge of the push plate.

[0008] The top surface of the rotating plate and the movable seat are connected by a hinge.

[0009] The beneficial effects of this utility model are as follows: Using hinges to connect the top surface of the joint between the rotating plate and the moving seat not only reduces the difficulty of processing, but also allows the rotating plate to fit tightly against the moving seat under the action of the limiting plate, ensuring the stability of the rotating plate and the moving seat in clamping the push rod during the transfer process. This results in a simple structure and high clamping efficiency. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1-5As shown, this embodiment provides a tappet transfer device for transferring the processed tappet 1 into the receiving frame 2, so as to facilitate batch cleaning of the tappet 1, thereby removing residual metal debris or oil stains on the surface of the tappet 1, and avoiding affecting subsequent surface carburizing, nitriding or hard chrome plating of the tappet 1.

[0020] Specifically, such as Figure 1 As shown, the device is located above the conveying end of the conveying assembly 10. The conveying assembly 10 includes a conveyor belt for conveying the pusher 1. Strip baffles are provided on both sides of the conveyor belt. The height of the baffles is lower than the axis of the pusher 1. An intercepting plate is provided at the end of the conveyor belt in the conveying direction to intercept the pusher 1, so that the pusher 1 is arranged sequentially on the conveyor belt along the length direction of the conveyor belt.

[0021] Specifically, such as Figures 1-2 As shown, the transfer assembly 20 includes a transfer seat 21, a telescopic rod 22, a rotating plate 23, a crossbeam 24, and a hinge 25. The crossbeam 24 spans directly above the centerline of the receiving frame 2, perpendicular to the conveyor belt's conveying direction, with one end of the crossbeam 24 spanning the end of the conveyor belt. The telescopic rod 22 is arranged vertically, and its upper end is slidably connected to the crossbeam 24, meaning the telescopic rod 22 is movable along the length of the crossbeam 24. The telescopic rod 22 can be electrically operated, and its movement along the length of the crossbeam 24 can be propelled by a linear cylinder.

[0022] The movable seat 21 is located at the lower end of the telescopic rod 22, and its length direction is parallel to the conveying direction of the conveyor belt. The cross-section of the movable seat 21 is an inverted L-shaped structure, with its horizontal part horizontally positioned and its inner right angle facing downwards. The vertical part of the movable seat 21 faces the direction of the receiving frame 2. The rotating plate 23 is vertically positioned on the side of the movable seat 21 away from the receiving frame 2. The top surface of the rotating plate 23 is rotatably connected to the top surface of the movable seat 21 facing the direction of the rotating plate 23 by a hinge 25 to reduce the processing process. When the rotating plate 23 rotates downwards towards the vertical direction of the movable seat 21, the side of the movable seat 21 facing the rotating plate 23 can be used to limit the rotating plate 23, ensuring that when the rotating plate 23 clamps the push rod 1, the rotating plate 23 rotates to directly below the movable seat 21 and does not damage the push rod 1.

[0023] Preferably, a layer of anti-collision pad is provided on the side of the rotating plate 23 facing the moving seat 21, which not only increases the friction and clamping force between the push rod 1 and the rotating plate 23, preventing the push rod 1 from slipping during the transfer process, but also protects the push rod 1 from scratches.

[0024] like Figures 2-3As shown, the locking assembly 30 includes a limiting plate 31, a vertical rod 32, a push plate 33, and a spring 34. The limiting plate 31 has a rectangular plate structure and is horizontally disposed at one end of the movable seat 21 along the width direction of the movable seat 21. One end of the limiting plate 31 is located on the top surface of the rotating plate 23. Rectangular holes are vertically penetrating at both ends of the horizontal part of the movable seat 21. The vertical rod 32 is vertically disposed on the bottom surface of the other end of the limiting plate 31. The cross-section of the vertical plate 32 is adapted to the rectangular holes, so that the vertical rod 32 passes vertically through the rectangular holes to prevent the vertical rod 32 from rotating when moving vertically. The push plate 33 is disposed at the lower end of the vertical rod 32, and has an inclined surface 331 on the side facing the rotating plate 23. When the rotating plate 23 is in a vertical state, the lower end of the inclined surface 331 corresponds to the bottom surface of the rotating plate 23. Spring 34 is inserted through vertical rod 32. The lower end of spring 34 abuts against the upper end of push plate 33, and the upper end of spring 34 abuts against the bottom surface of horizontal part of movable seat 21.

[0025] Preferably, the height of the rotating plate 23 is less than the height of the vertical part of the moving seat 21, so that when clamping the pusher 1, the bottom surface of the push plate 33 is blocked by the conveying assembly 10, so that the angle of the inclined surface 331 pushing the rotating plate 23 to rotate upward away from the pusher 1 is as small as possible. The bottom surface of the rotating plate 23 shall not be higher than the axis of the pusher 1 located on the conveyor belt, so as to ensure smooth clamping and stable clamping of the pusher 1 by the rotating plate 23.

[0026] The specific usage method is as follows: The pushers 1 are placed sequentially on the conveyor belt for transport, with the closed end of each pusher 1 facing the direction of the receiving frame 2. Under the interception action of the intercepting plate, a certain number of pushers 1 are arranged sequentially along the length of the conveyor belt. Then, the telescopic rod 22 is activated, moving it directly above the pushers 1 arranged on the conveyor belt. The telescopic rod 22 is then extended vertically downwards, causing the inner side of the vertical part of the moving seat 21 to extend vertically downwards along the closed end face of each pusher 1, presenting a shape as shown in the image. Figure 6 As shown, the rotating plate 23 is slightly opened away from the opening of the pusher 1 under the action of the inclined surface 331, so that the pusher 1 is contained between the horizontal part of the moving seat 21 and the rotating plate 23. The telescopic rod 22 moves vertically upward, the bottom surface of the push plate 33 loses the force of the conveying component 10, and under the action of the spring 34, the bottom surface of the limiting plate 31 presses against the top surface of the rotating plate 23, and under the action of the side of the horizontal part of the moving seat 21, the rotating plate 23 is kept vertical, so that the pusher 1 is firmly clamped between the horizontal part of the moving seat 21 and the rotating plate 23, thereby realizing the clamping of the pusher 1.

[0027] like Figures 4-5As shown, after the telescopic rod 22 moves along the crossbeam 24 to the top of the receiving frame 2, the movement is paused, and the telescopic rod 22 moves vertically downward. The push rod 1 is inserted vertically downward along the notch in the receiving frame 2. During the insertion process, when the lower side of the closed end of the push rod 1 is a certain distance from the bottom of the notch, the bottom surface of the push plate 33 contacts the lower part of the clamping plate with the notch. As the telescopic rod 22 continues to move downward, the closed end of the push rod 1 falls into the notch. The rotating plate 23 rotates away from the push rod 1 under the action of the inclined surface 331, thereby releasing the clamping of the push rod 1. The other end of the push rod 1 falls automatically into the receiving frame 2 under the action of gravity, so that the push rod 1 is inserted into the receiving frame 2 in an inclined state.

[0028] Finally, the telescopic rod 22 is activated and moves vertically upward out of the receiving frame 2, preparing for the transfer to the next row of masts 1.

[0029] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
