Abstract
The utility model relates to a rotation limit assistance tool for screwing down a bolt of a water pump pulley of an engine. The rotation limit assistance tool comprises an assistance tool body, a rotating sleeve and a locating sleeve, wherein the rotating sleeve is arranged in the assistance tool body; the rotating sleeve is matched with the assistance tool body by a bearing, and can rotate relative to the assistance tool body; the rotating sleeve is fixed by an elastic check ring; the assistance tool body is fixedly connected with the locating sleeve.
Description
Technical field
The utility model belongs to the engine assembly field, and the assembling of mean engine water pump pulley specifically refers to that a kind of engine water pump belt wheel bolt tightening turns accessory by limit.
Background technology
Water pump and belt pulley thereof are parts very crucial on engine.During pump working, its power is to be passed to water pump pulley by bent axle by belt, and then driving water pump rotary work, and between water pump pulley and water pump, be by 4 bolted on connections, while using tightening tool to tight a bolt, because tightening tool and bolt pivot depart from the belt pulley center, cause belt pulley due to discontinuity, can be together with the water pump rotation, direction of rotation is consistent with the bolt tightening direction, thereby causes the belt pulley bolt directly to tighten.
Existing scheme is the belt pulley of holding with a firm grip manually, by manpower, offsets the suffered power of belt pulley, and another hand operated tightening tool tights a bolt.Therefore, following shortcoming is arranged:
1, pulley surface is very smooth, and operation easier is larger, and efficiency is low.
2, because the tightening tool impact adopted is larger, easily hurt sb.'s feelings, certain potential safety hazard is arranged.
The utility model content
The purpose of this utility model is to provide a kind of engine water pump belt wheel bolt tightening and turns accessory by limit, by accessory, the belt pulley limit is turned, and while tightening the belt pulley bolt, water pump and belt pulley can not rotate, and have solved the problem that water pump belt bolt can't directly be tightened.
The utility model is achieved through the following technical solutions:
A kind of engine water pump belt wheel bolt tightening turns accessory by limit, comprises accessory body, revolving sleeve and positioning sleeve; Revolving sleeve is arranged in the accessory body, rotates by bearing fit and with respect to the accessory body between revolving sleeve and accessory body, and fixes by circlip; The accessory body is fixedly connected with positioning sleeve.
Three jaws are arranged on described positioning sleeve.
Between positioning sleeve and accessory body, be connected by screw.
The material of described positioning sleeve is nylon.
Described circlip includes circlip for hole and circlip for shaft.
When positioning sleeve is enclosed within on water pump pulley, on the circumference that the center of accessory body and revolving sleeve distributes at the water pump pulley bolt.
The utility model beneficial effect compared with the existing technology is:
This accessory is simple to operate, directly accessory is enclosed within on belt pulley, starts tightening tool and gets final product.While tightening the water pump pulley bolt tightening, by the limit to belt pulley, turn the problem that while having solved the belt pulley bolt tightening, belt pulley can rotate thereupon, finally realized tightening of bolt, and greatly reduced operation easier, and improved efficiency of assembling, also guaranteed operating personnel's safety.

The specific embodiment
Below describe the technical solution of the utility model in detail by specific embodiment, should be understood that, following embodiment is only exemplary, only can be used for explaining and the explanation the technical solution of the utility model, and can not to be interpreted as is the restriction to technical solutions of the utility model.
At this, it should be noted that, the technical solution of the utility model is not only for water pump pulley, and can be applied to the field that other has analogue.
Below in conjunction with below in conjunction with accompanying drawing, the utility model being further illustrated.
As shown in Figure 1, the utility model comprises accessory body 1, revolving sleeve 2,3 three critical pieces of positioning sleeve.
As shown in Figure 2, limit turns accessory and is fixed on tightening tool 12 by interior hexagonal holding screw 4, and revolving sleeve 2 and 7 of double-sided belt dust cap seal deep groove ball bearings are interference fit, and are fixed by circlip for hole 6 and circlip for shaft 8.
As shown in Figure 3 and Figure 4, while tightening the belt pulley bolt, at first manually bolt 10 is preloaded onto on belt pulley 9, and after manually tightening several teeth, again accessory positioning sleeve 3 is enclosed within on water pump pulley 9, tightening tool sleeve 13 is aimed at a belt pulley bolt 10 simultaneously, start tightening tool 12, tightening tool front end delivery band moving sleeve 13 and revolving sleeve 2 rotations, and accessory body 1, tightening tool body and positioning sleeve 3 are fixed, by positioning sleeve 3, the fixing limit of water pump pulley is turned simultaneously, allow the belt pulley can not tightening and rotate with bolt, finally realize tightening of belt pulley bolt 10, and precision is tightened in assurance.Positioning sleeve 3 connects by socket cap screw 5 and accessory body 1, and the material of positioning sleeve 3 is nylon, to prevent from scratching water pump pulley 9, three jaws is arranged on positioning sleeve 3, but by three jaw fast pulleies 9.
When positioning sleeve is enclosed within on water pump pulley, on the circumference that the center of accessory body and revolving sleeve distributes at the water pump pulley bolt.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that do not break away from principle of the present utility model and spirit can be carried out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is by claims and be equal to and limit.
