Description
Technical Field
The utility model relates to an engine assembly technical field, more specifically say, it relates to a last axle bush frock.
Background
At present, a bent bearing bush for assembling an engine adopts a bearing bush pressing surface mounting mode, and after a tile is placed at a mounting position, a device is used for pressing the middle part of the bearing bush for press mounting. At present, the shaft bushing pressing mode is low in efficiency, the cleanliness of an engine is not guaranteed, the conditions that one side is high, the other side is low and the pressure is not in place are easily caused, the pressure is required to be pressed again, the beat of a post is long, and the labor intensity of workers is high. In addition, because the bearing bush and the crankshaft are in relative motion with high pressure and high speed, the bearing bush burning situation is often caused, and the mass of the engine is greatly reduced. The method for pressing the bearing bush cannot meet the existing production quality requirement.
The existing method for pressing the bearing bush mainly has the following two defects: 1. the efficiency is low, the conditions that the high-side low-pressure mounting and the low-pressure mounting are not in place are easily caused, the press mounting needs to be carried out again, the beat of a post is long, the labor intensity of workers is high, the efficiency is low, and the requirements of production beats are not met; 2. the quality is poor, the press mounting method directly contacts with the bush surface, the hidden danger of pollution exists, the bush and the crankshaft are in relative motion with high pressure and high speed, the bush burning situation is frequently caused, and the quality of the engine is greatly reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is not enough to the above-mentioned of prior art, the utility model aims at providing an efficient and high pressure axle bush frock of pressure equipment quality.
In order to achieve the purpose, the utility model provides a last axle bush frock, which comprises a pressing plate and i, the one end of clamp plate is equipped with the locating pin, be equipped with the connecting rod of perpendicular setting on the clamp plate, the upper end of connecting rod is equipped with the handle.
Furthermore, the handle is sleeved at the upper end of the connecting rod, and the upper end and the lower end of the handle are provided with limiting convex edges.
Furthermore, the top end of the handle is of a plane structure.
Furthermore, the connecting rod is connected with the pressure plate through threads.
Furthermore, the central line of the connecting rod is coincident with the central line of the pressure plate.
Advantageous effects
Compared with the prior art, the utility model discloses a pressure axle bush frock's beneficial effect as follows:
(1) efficient when carrying out the pressure axle bush during operation, the locating pin card is on main shaft cover installation locating hole, and staff's hand is held the handle, presses axle bush both edges parallel and level main shaft hole downwards hard a little, realizes quick pressure equipment axle bush, need not repeated pressure equipment, and is convenient fast, disposable operation has reduced the pressure axle bush time.
(2) The bearing bush has good quality, only contacts two edges of the bearing bush and does not contact the outside when the bearing bush is pressed, and is more favorable for ensuring the cleanliness of the whole bearing bush, thereby ensuring the assembly quality of an engine.
Drawings
FIG. 1 is a front view of the bearing shell pressing tool of the present invention;
fig. 2 is an enlarged sectional view of a part of the structure of the bearing bush pressing tool of the present invention;
fig. 3 is a schematic view of the press-fitting tool of the present invention.
In the figure: 1. pressing a plate; 2. positioning pins; 3. a connecting rod; 4. a handle; 5. a limiting convex edge; 6. a clamping block; 7. a clamping groove.
Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.
The specific implementation manner of the utility model is as follows: as shown in fig. 1-3, a bearing bush pressing tool comprises a pressing plate 1, a positioning pin 2 is arranged at one end of the pressing plate 1, a connecting rod 3 vertically arranged is arranged on the pressing plate 1, and a handle 4 is arranged at the upper end of the connecting rod 3.
In this 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 the limiting convex edges 5.
The top end of the handle 4 is of a plane structure.
The connecting rod 3 is connected with the pressure plate 1 through screw threads.
The central line of the connecting rod 3 is superposed with the central line of the pressure plate 1.
The positioning pin 2 can be locked with the pressure plate 1 through threads.
The side wall protrusion of locating pin 2 is provided with fixture block 6, is equipped with the through-hole with locating pin looks adaptation on the clamp plate 1, is provided with vertical downwardly extending earlier on the pore wall of through-hole, then the draw-in groove 7 that the circumference extended the setting, draw-in groove 7 and fixture block 6 block, and draw-in groove 7 is the L type.
The operation method comprises the following steps: arranging a pressure plate 1, arranging a positioning pin 2 which can be matched with a main shaft cover mounting positioning hole of a cylinder body at one end of the pressure plate 1, vertically arranging a connecting rod 3 on the pressure plate 1, and arranging a handle 4 at the upper end of the connecting rod 3; the bearing bush is placed above a bearing bush mounting groove on a main shaft hole of the cylinder body, the pressing plate 1 is abutted to two ends of the bearing bush, the positioning pin 2 on the pressing plate 1 is inserted into a main shaft cover mounting positioning hole, and the bearing bush can be pressed and mounted in place by applying vertical force to the pressing plate 1 through the handle 4.
