Description

Manual assembly tool for piston pin clamp spring

Technical Field

The utility model relates to an assembly technique and equipment field, concretely relates to piston pin jump ring manual assembly frock.

Background

In the assembly of the engine, the clamp springs at the two ends of the piston pin are steel wire clamp springs, the wire diameter is thick, great force is required for contraction, the diameter of the clamp springs is small, and the manual assembly difficulty is high; because the thickness of the piston is limited, the wall thickness of two sides of the clamp spring groove is small, and the piston is deformed due to overlarge stress in the assembling process. Therefore, in the assembly process of the piston pin clamp spring, the piston pin clamp spring must be firstly compressed to a diameter smaller than the diameter of the piston pin hole by using a tool and then pressed into the clamp spring groove. Traditional piston pin jump ring pressure equipment has two actions, compresses the jump ring diameter earlier to being less than piston pin hole diameter, then impresses the jump ring in the jump ring inslot to the jump ring can only go up a material once.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a defect and not enough to prior art, provide piston pin jump ring manual assembly frock, its structural design is reasonable, can satisfy most piston pin jump ring pressure equipment technology, and the success rate is high, and the action is simple, has great spreading value.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the guide pin comprises a guide pin 1, a guide sleeve 2, a clamp spring compression block 3, a compression block reset spring 4, a shell 5, a clamp spring material clamp 6, a clamp spring compression lever 7, a clamp spring material clamp guide rod 8, a clamp spring pressure head 9, a clamp spring compression pull rod 10, a handle 11 and a handle reset spring 12, wherein the upper part of the guide pin 1 is sleeved in the guide sleeve 2, the compression block reset spring 4 is arranged on the left side of the clamp spring compression block 3, the clamp spring material clamp 6 is fixedly connected to one side of the shell 5, the clamp spring compression lever 7 is arranged inside the shell 5, the clamp spring material clamp guide rod 8 is fixedly connected with the clamp spring material clamp 6, the clamp spring compression pull rod 10 is connected to the upper part of the clamp spring compression lever 7 through the clamp spring pressure head 9, the handle 11 is fixedly connected with.

The handle 11 is an I-shaped handle.

The utility model discloses a theory of operation: the assembly tool is mainly arranged on an assembly line of a piston connecting rod of an engine and used for manually pressing a piston pin clamp spring; the tool is light and only has about 1 KG; during assembly, an operator only needs to align the positioning pin with the piston pin hole and slide the handle downwards until the handle is heard, so that press mounting can be completed, and the operation is simple; a plurality of clamp springs are loaded to the clamp spring material clamp at one time before press mounting, and after each press mounting is completed, the clamp springs at the back can be automatically loaded to a press mounting position, so that automatic clip type loading is realized; in the pressure equipment in-process, at the anterior segment distance of gliding handle, the frock can compress the jump ring through jump ring compression lever and jump ring compression piece automatic compression jump ring to the diameter and be less than piston pin hole diameter, and at the latter half of gliding handle, the frock can be impressed the jump ring after the compression in the jump ring inslot, realizes compressing and impress once only accomplishing.

After the technical scheme is adopted, the utility model discloses beneficial effect does: 1. the cartridge clip type feeding realizes automatic feeding, and independent feeding is not needed in each press mounting; 2. the same action of radial compression and axial pressing of the clamp spring is completed; 3. the operation is simple, and the whole press mounting process only has a process of sliding the handle downwards; 4. light weight and reduced labor intensity of operators. In general, the structure is reasonable in design, can meet the requirements of most piston pin clamp spring press-fitting processes, and is high in success rate, simple in action and high in popularization value.
