Deep hole sealing ring assembler

Abstract

The invention discloses a deep hole sealing ring assembler which is characterized in that a lifting component moving in the axial direction is arranged on a shell of the assembler, and a sealing ring is arranged between the shell and the lifting component and is vertically stretched by the lifting component. The plane radius of the sealing ring is reduced through the lifting structure in the assembler, so that the sealing ring is matched with the bottom positioning structure to ensure that the sealing ring is accurately filled into a deep hole groove after being enlarged after passing through the deep hole.

Description

Technical Field

[0001] The invention relates to the field of shock absorber assembly tooling, in particular to a deep hole sealing ring assembler. Background Art

[0002] The installation of deep hole concave sealing rings is very troublesome. Due to the small hole depth and diameter, the sealing ring cannot be directly installed and pressed into the inner groove by hand. Most existing solutions are to use a triangular clamp to fold the sealing ring in reverse, reduce its projection area so that it can pass through the deep hole, and then press the sealing ring into the groove by hand or by pressing tooling. This assembly method has complex procedures, low efficiency, and is highly dependent on the manual proficiency of workers. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the object of the present invention is to provide a deep hole sealing ring assembler to simplify the difficulty of installing the deep hole sealing ring.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A deep hole sealing ring assembler is provided with a lifting component which moves in the axial direction on the shell of the assembler, and the sealing ring is placed between the shell and the lifting component and is vertically stretched by the lifting component.

[0006] In a preferred embodiment of the present invention, a movable hook groove is provided on one side of the lifting component, and a fixed hook groove is provided on the outer periphery of the shell to cooperate with the movable hook groove to hook the sealing ring, and the fixed hook groove extends in an arc shape on the outer peripheral surface of the shell.

[0007] In a preferred embodiment of the present invention, when the lifting component is located at the bottom position of the moving stroke, the virtual extension lines of the movable hook groove and the fixed hook groove form a circle on the shell surface, and the circumference of the circle is smaller than the inner diameter of the sealing ring.

[0008] In a preferred embodiment of the present invention, a cutout is provided on the shell, and the cutout prevents the sealing ring from interfering with the shell when the sealing ring is stretched.

[0009] In a preferred embodiment of the present invention, the lifting component is reset by elastic force through a spring arranged in the housing.

[0010] In a preferred embodiment of the present invention, a limit pin is further provided on the housing, and the lifting component is stopped by the limit pin when the lifting component is located at the top position of the moving stroke.

[0011] In a preferred embodiment of the present invention, a base is provided at the bottom of the housing.

[0012] In a preferred embodiment of the present invention, the handle is a bolt structure.

[0013] The beneficial effects of the present invention are:

[0014] The deep hole sealing ring assembler provided by the present invention reduces the plane radius of the sealing ring through the lifting structure in the assembler, so that the sealing ring passes through the deep hole, and cooperates with the bottom positioning structure to ensure that the sealing ring is accurately filled into the deep hole groove after being enlarged.

[0019] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings. The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0020] The singular forms "a", "an", "said" and "the" used in the specification include plural forms unless clearly indicated.

[0021] In the specification, when an element is referred to as being “on,” “fixed” to, “connected to,” “engaged to,” or the like, the element may be directly on, fixed to, connected to, engaged to, or contacting the other element, or intervening elements may be present.

[0022] The following will describe exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in a variety of different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all drawings, the same reference numerals represent the same or functionally identical elements.

[0023] Figure 1A deep hole sealing ring assembler is shown, which mainly includes a lifting component arranged in a housing 10 and a handle 20 and a spring 30 for controlling the lifting component 30.

[0024] Combined with reference Figure 2 A fixed hook groove 12 is also provided at the lower part of the housing 10. Since there is a cutout 13 on one side of the housing 10, the fixed hook groove 12 forms a semicircular arc shape on the surface of the housing 10. The lifting component 30 is on the same side as the cutout 13 and can move up and down in the vertical direction. The movable hook groove 31 at the bottom is always placed within the projection range of the cutout 13. When the lifting component 30 moves to the bottom lower limit, the virtual extension lines of the movable hook groove 31 and the fixed hook groove 12 intersect in a circle to form a complete virtual circle. One end of the sealing ring 40 is sleeved on the fixed hook groove 12, and the other end is hooked on the movable hook groove 31. Since the circumference of the sealing ring 40 is greater than the outer diameter of the virtual circle, when the movable hook groove 31 moves upward, the sealing ring 40 is vertically stretched and fixed, and the sealing ring 40 will not interfere with the cutout 13.

[0025] A spring 30 is provided at the bottom of the lifting component 30, and a handle 20 extending upward for operation by a person is provided at the top. The lifting component 30 can be moved back and forth by pressing the handle 20 in cooperation with the spring 30. A limit pin 14 is provided at the upper part of the housing 10 as the upper limit of the movement of the lifting component 30. In one embodiment, the end 21 of the handle 20 can be provided as a hexagonal bolt structure, so that the handle 20 and the lifting component 30 can be assembled by thread.

[0026] Figure 3 The assembly tool is shown in the figure. The sealing ring 40 is stretched by the lifting member 30, reducing the radius of the projected area in the vertical direction, so that it can pass through the hole of the deep hole workpiece 50 with the assembly tool. The base 11 is designed so that when the assembly tool touches the bottom, the virtual circle formed by the fixed hook groove 12 and the movable hook groove 31 is flush with the deep hole groove 51 in the horizontal direction. The lifting member 30 is gradually moved downward by operating the handle 20, and the plane radius of the sealing ring 40 gradually increases, so it moves from the fixed hook groove 12 to the deep hole groove 51, and finally completely fills the deep hole groove 51.
