Description

Technical Field

[0001] This utility model belongs to the technical field of tappet processing equipment, and in particular relates to an automatic loading and unloading device for tappet end processing. Background Technology

[0002] A tappet is a cylindrical component with a circular opening at one end and a plate at the other end, hereinafter referred to as a workpiece. Its end processing mainly involves polishing and grinding the end to optimize its surface quality and improve its wear resistance and reliability.

[0003] Currently, most workpiece grinding is done manually. Workers sit in front of the grinding machine, place the workpiece to be ground to one side, and hold one end of the workpiece to make it contact the grinding wheel during grinding. This method is not only inefficient, but if the worker does not hold it firmly, the workpiece can easily slip out, damaging the side of the workpiece and affecting its quality. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides an automatic loading and unloading device for the end processing of tappets, which replaces manual loading and unloading during the end grinding process of the tappets and avoids damage to the surface quality of the tappets.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed: An automatic loading and unloading device for processing the end of a tappet is provided on one side of the output end of a grinding mechanism. The device includes a turntable assembly and an input assembly and an output assembly that are sequentially distributed along the rotation direction of the turntable assembly. The input assembly and the output assembly are respectively arranged on both sides of the grinding mechanism. The turntable assembly includes a turntable with a guide plate fixedly connected to a frame. The top surface of the guide plate is recessed with an annular groove. The outer circumference of the turntable is provided with a transfer component in a circular array. The transfer component is arranged to move radially along the turntable. One end of the component is used to support the ejected push rod, and the other end is slidably connected to the annular groove. The annular groove is recessed inward toward its axis at a preset position. The input component includes a conveyor belt for conveying the pusher, with a linear mechanism on one side of the conveyor belt in the conveying direction that outputs radially along the turntable, and a discharge port on the other side. The linear mechanism is used to push the pusher from the discharge port to the transfer component. The output assembly is located on the outer periphery of the turntable and includes an output belt for receiving and outputting the processed tappets.

[0006] Furthermore, the turntable is provided with an outer ring plate, and an inner ring plate is concentrically provided inside the outer ring plate. The outer ring plate has a circular array of holes running through it. The outer ring plate has square holes corresponding to the circular holes one by one on its outer ring. The transfer component includes a T-shaped rod, the vertical part of which passes through the circular hole. The horizontal part of the T-shaped rod is coaxially provided with a square rod. One end of the square rod passes through the square hole and is provided with a limiting seat. The bottom surface of the limiting seat is provided with a support rod. The lower end of the support rod is slidably engaged with the annular groove. A cylindrical spring passes through the square rod, and its two ends abut against the horizontal part of the T-shaped rod and the outer wall of the inner ring plate, respectively.

[0007] Furthermore, the cross-section of the annular groove is an inverted T-shaped structure, and the lower end of the support rod is provided with a rotating sleeve, which is located inside the horizontal part of the annular groove and rolls in contact with both sides of the horizontal part of the annular groove.

[0008] Furthermore, the T-shaped bar has a circular cross-section, and its vertical part is covered with a rubber layer.

[0009] Furthermore, the centerline of the output band along its length overlaps with the horizontal projection of the radial direction of the recessed part of the annular groove.

[0010] The beneficial effects of this utility model are as follows: During the end grinding process of the push rod, the push rod can be automatically inserted into the T-shaped rod to realize automatic feeding of the push rod. It is recessed inward at a predetermined position in the guide groove so that the T-shaped rod carrying the ground T-shaped rod can automatically retract into the outer ring plate, thereby realizing automatic discharge, replacing manual operation and improving work efficiency.

Detailed Implementation

[0017] 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.

[0018] like Figures 1-4 As shown, this embodiment provides an automatic loading and unloading device for processing the end of a tappet. It is installed on one side of a movable grinding mechanism. The device includes a turntable assembly 10, an input assembly 20, and an output assembly 30. The rotation center of the turntable assembly 10 corresponds to the front of the center line of the moving direction of the grinding mechanism. The input assembly 20 and the output assembly 30 are arranged sequentially on the outer periphery of the turntable assembly 10 along the rotation direction of the turntable assembly 10, and the input assembly 20 and the output assembly 30 are located on both sides of the grinding mechanism.

[0019] Specifically, such as Figures 1-3 As shown, the turntable assembly 10 includes a turntable 11, a guide plate 12, a transfer component 13, an outer ring plate 14, and an inner ring plate 15. The turntable 11 has a horizontally arranged disc-shaped structure, and its bottom surface is coaxially provided with a rotating mechanism with the output end pointing vertically upward. The guide plate 12 is coaxially arranged on the top surface of the turntable 11, and a vertically upward mounting rod is provided at the center of the top surface of the guide plate 12. The mounting rod is fixedly connected to a frame. The outer ring plate 14 and the inner ring plate 15 are concentrically arranged on the top surface of the turntable 11, and the diameter of the inner ring plate 15 is smaller than the diameter of the outer ring plate 14. The inner ring plate 15 is located on the outer periphery of the guide plate 12.

[0020] An annular groove 121 is recessed on the top surface of the guide plate 12. The annular groove 121 is recessed in the direction of its axis at a preset position so that the projection of the recessed position on the turntable 11 is distributed at a 120° angle with the projection of the discharge port 13 and the grinding mechanism on the horizontal plane. The cross-section of the annular groove 121 is an inverted T-shaped structure.

[0021] like Figure 3 As shown, the outer ring plate 14 has circular holes 141 arranged in a circular array on its wall, and the inner ring plate 15 has square holes 151 arranged in a circular array on its wall, with each square hole 151 corresponding to a circular hole 141.

[0022] like Figures 1-2 , Figure 4 As shown, the number of transfer components 13 is the same as the number of circular holes 141. Multiple transfer components 13 are arranged in a circular array along the outer periphery of the outer ring plate 14. The material loading assembly 13 includes a T-shaped rod 131, a square rod 132, a limiting seat 133, a support rod 134, a cylindrical spring 135, and a rotating sleeve 136. The T-shaped rod 131 has a circular cross-section, with its vertical part passing through the circular hole 141. The horizontal part of the T-shaped rod 131 is located between the outer ring plate 14 and the inner ring plate 15. One end of the square rod 132 is coaxially connected to the horizontal part of the T-shaped rod 131, and the other end of the square rod 132 passes through the square hole 151. The cylindrical spring 135 is sleeved on the square hole 151. The outer wall of the square rod 132 is designed so that one end of the cylindrical spring 135 abuts against the horizontal part of the T-shaped rod 131, and the other end abuts against the outer wall of the inner ring plate 15. The limiting seat 133 is located at the other end of the square rod 132 and is located inside the inner ring plate 15. The bottom surface of the limiting seat 133 is a certain distance from the top surface of the guide plate 12. The support rod 134 is perpendicular to the top surface of the limiting seat 133. The lower end of the support rod 134 extends vertically downward into the guide groove 121 along the vertical part of the guide groove 121. The rotating sleeve 136 is rotatably located at the lower end of the support rod 134, and the outer wall of the rotating sleeve 136 is in rolling connection with the inner walls on both sides of the horizontal part of the guide groove 121. When the turntable 11 rotates, it drives the rotating parts 13, the outer ring plate 14, and the inner ring plate 15 to rotate synchronously, thereby causing the rotating sleeve 136 to roll along the trajectory of the horizontal part of the guide groove 221.

[0023] Preferably, to facilitate the insertion of the tappet 1 into the vertical part of the T-shaped rod 131, a tapered surface is provided at the end of the vertical part of the T-shaped rod 131 away from the horizontal part.

[0024] In a further preferred embodiment, to prevent the pusher 1 from being thrown out by the centrifugal force generated by the rotation of the turntable 11 after it is inserted into the T-shaped rod 131, a rubber layer is provided on the outer wall of the vertical part of the T-shaped rod 131.

[0025] Specific operating procedures: The end of the pusher 1 with an opening is directed toward the side where the discharge port 23 is located and conveyed on the conveyor belt 21. The turntable 11 is activated so that the axis of the T-shaped rod 131 corresponding to one of the transfer parts 13 is aligned with the vertical centerline of the discharge port 23. When the pusher 1 is conveyed to the end of the conveyor belt 21 in the conveying direction, the linear mechanism 22 is activated so that the linear mechanism 22 pushes out the end of the conveyor belt 21 in the conveying direction so that the pusher 1 is inserted into the vertical part of the corresponding T-shaped rod 131, thereby realizing automatic feeding.

[0026] The turntable 11 is restarted and continues to rotate. When the T-shaped rod 131 with the push post 1 inserted rotates to the front of the vertical center line of the mounting base 122, the turntable 11 stops. At this time, the grinding mechanism is started, and the grinding disc of the grinding mechanism rotates and moves towards the push post 1 to grind the push post 1.

[0027] After grinding, when the transfer part 13 with the ground pusher 1 inserted moves to the recess of the guide groove 121 with the rotation of the turntable 11, the square rod 132 moves inward along the axial direction of the corresponding square hole 151, so that the T-shaped rod 131 moves inward along the corresponding round hole 141, so that the pusher 1 automatically disengages under the obstruction of the outer ring plate 14 and enters the output belt 31, so that the output belt 31 outputs the ground pusher 1 to achieve automatic material discharge.

[0028] 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.
