Description

A press bearing tooling

technical field

The utility model relates to the technical field of engine assembly, in particular to a press bearing bush tooling.

Background technique

At present, the engine assembly crankshaft bush adopts the pressing pad surface installation method. After the tile is placed in the installation position, the middle part of the bearing bush is pressed with a tool for press fitting. At present, this method of pressing the bearing bush has low efficiency, the cleanliness of the engine is not guaranteed, and it is easy to cause the situation that one side is high and the other is low, and the pressure is not in place. In addition, due to the relative movement between the bearing bush and the crankshaft at high pressure and high speed, the burning of the bearing is often caused, which greatly reduces the quality of the engine. The method of using this kind of pressing bush cannot satisfy the existing production quality requirements.

The existing method of pressing the bearing bush mainly has the following two shortcomings: 1. The efficiency is low, and it is easy to cause the situation that one side is high and the other is low, and the pressing is not in place. Does not meet the production takt time requirements; 2. Poor quality, the press-fitting method directly contacts the surface of the tile, and there is a hidden danger of contamination outside. The bearing bush and the crankshaft move relative to each other with high pressure and high speed, which often causes tile burning, which greatly reduces the quality of the engine.

Utility model content

The technical problem to be solved by the present utility model is aimed at the above-mentioned deficiencies of the prior art, and the purpose of the present utility model is to provide a press bearing bush tooling with fast efficiency and high press fitting quality.

In order to achieve the above purpose, the present utility model provides a pressure bearing bush tooling, which includes a pressure plate, one end of the pressure plate is provided with a positioning pin, the pressure plate is provided with a vertically arranged connecting rod, and the upper end of the connecting rod is provided with a handle .

Furthermore, the handle is sleeved on the upper end of the connecting rod, and the upper and lower ends of the handle are provided with limiting ledges.

Further, the top of the handle is a plane structure.

Further, the connecting rod and the pressing plate are connected by screw threads.

Further, the center line of the connecting rod coincides with the center line of the pressing plate.

beneficial effect

Compared with the prior art, the beneficial effects of the pressing bush tooling of the present utility model are as follows:

(1) High efficiency When pressing the bearing bush, the positioning pin is stuck on the installation positioning hole of the main shaft cover. The employee holds the handle and presses the two edges of the bearing bush downward with a little force to be flush with the main shaft hole, so as to realize the rapid pressing of the bearing bush without repetition. Press-fit, fast and convenient, one-time operation, reducing the time of pressing the bearing bush.

(2) The quality is good. When the bearing bush is pressed, only the two edges of the bearing bush are contacted, and the outside is not touched, which is more conducive to ensuring the cleanliness of the whole piece of tile, thereby ensuring the quality of the engine assembly.

Detailed ways

The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

The specific embodiment of the present utility model is as follows: as shown in Figures 1-3, a pressure bearing bush tooling includes a pressure plate 1, one end of the pressure plate 1 is provided with a positioning pin 2, and the pressure plate 1 is provided with a vertically arranged connecting rod 3 , the upper end of the connecting rod 3 is provided with a handle 4 .

In the present embodiment, the handle 4 is sleeved on the upper end of the connecting rod 3 , and the upper and lower ends of the handle 4 are provided with limiting convex edges 5 .

The top of the handle 4 is a plane structure.

The connecting rod 3 and the pressing plate 1 are connected by screws.

The center line of the connecting rod 3 coincides with the center line of the pressing plate 1 .

The positioning pin 2 can be locked with the pressing plate 1 through a thread.

The side wall of the positioning pin 2 is protruded with a blocking block 6, and the pressing plate 1 is provided with a through hole that is adapted to the positioning pin. The card slot 7 is engaged with the card block 6, and the card slot 7 is L-shaped.

The operation method is as follows: set a pressure plate 1 and set a positioning pin 2 at one end of the pressure plate 1 that can be adapted to the installation positioning hole of the main shaft cover of the cylinder body, set a connecting rod 3 on the pressure plate 1 vertically, and set a connecting rod 3 on the upper end. Handle 4; place the bearing bush above the bearing bush installation groove on the main shaft hole of the cylinder body, abut the pressure plate 1 with both ends of the bearing bush, and insert the positioning pin 2 on the pressure plate 1 into the installation positioning hole of the spindle cover, and apply pressure to the pressure plate 1 through the handle 4 A vertical force can press the bearing pad into place.

When the bearing pad is placed over the bearing pad mounting groove on the main shaft hole of the cylinder block, the two ends of the bearing are set flush. The employee holds the handle 5 and presses the bearing bush downward with a little force so that the two edges are flush with the main shaft hole, so as to realize the quick press-fitting of the bearing bush.

This scheme of pressing the bearing bush has high pressing efficiency. During the pressing of the bearing bush, the positioning pin 2 is stuck on the installation positioning hole of the main shaft cover. The employee holds the handle 4 and presses down the two edges of the bearing bush to be flush with the main shaft hole. Achieving quick press-fitting of the bearing bush, without repeated pressing, fast and convenient, one-time operation, saving 25 seconds of press-fitting time per engine compared to the previous method; good quality, when the pressing bush is tooled on the pressing bush, it only touches the two edges of the bearing bush, Without contact with the outside, it is more conducive to ensure the cleanliness of the entire tile, thereby ensuring the quality of engine assembly.

In the present embodiment, the handle 4 is sleeved on the upper end of the connecting rod 3 , and the upper and lower ends of the handle 4 are provided with limiting convex edges 5 .

In this embodiment, the top of the handle 4 is a plane structure, and a pressing device can be used to apply pressure to the top of the handle 4 .

The connecting rod 3 and the pressing plate 1 are connected by screws, and the center line of the connecting rod 3 coincides with the center line of the pressing plate 1 .

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, some modifications and improvements can be made without departing from the structure of the present invention, which will not affect the implementation of the present invention. effect and the applicability of the patent.
