Abstract
Provided is a novel assembly tool for a valve spring. The novel assembly tool aims at solving the problem that assembly and disassembly of a valve spring locking clamp are difficult and labor-wasting. The novel assembly tool for the valve spring comprises a clamping base (5) which is annular, wherein a groove is formed in an inner circle, two rotary fixing bodies (6) are arranged in the groove, one end of an outer circle of the clamping base (5) is fixedly connected with a handle (7), the other end of the outer circle of the clamping base (5) is fixedly connected with a bolt (4), the upper portion of the bolt (4) penetrates trough a pressing plate (1), the upper end, penetrating through a hole of the bolt (4), of the pressing plate (1) is provided with a guide column (2), and the upper end of the guide column (2) is provided with a nut (3) which is in threaded connection with the bolt (4). The novel assembly tool for the valve spring has the advantages of being simple and reasonable in structure, low in cost, easy to manufacture, small in size, low in weight and convenient to carry, prevents the fact that a cylinder cover is conveyed to a pressure machine for detachment, and facilitates on-site use.
Description
Technical field
The utility model relates to valve-spring tool, especially novel valve spring assembly tool.
Background technology
Valve-spring tool is that instrument commonly used is repaired in the engine valve dismounting, when valve collet and valve oil seal assembling, need two people to cooperate usually, after one personal instrument compresses valve spring, another person is after valve collet exposes, the valve collet of two halves is disassembled, because the valve mechanism compact conformation, the compression stress of valve spring is very big, two people operating spaces are narrow and fly out potential safety hazard and wastes of manpower such as valve spring bounce-back with locker.
Summary of the invention
In order to solve the problem that exists in the above-mentioned background technology, the utility model provides a kind of novel valve spring assembly tool, this novel valve spring assembly tool is repaired and can by other other instruments valve spring machine spring base locker do not assembled in the dismounting of carrying out engine valve spring, but only needs just complete operation of a people.
The technical solution of the utility model is: this novel valve spring assembly tool comprises clamp base, described clamp base is annular, interior annulus is fluted, groove is built-in with two rotational fixation bodies, the fixedly connected handle of described clamp base outer toroid and connecting bolt, pressing plate is passed on bolt top, and there is lead the upper end, hole that pressing plate passes bolt, and there is the nut thread connecting bolt lead upper end.
In the such scheme, described clamp base is annular, and this annulus and set bolt rightabout one end are jagged, and the narrowest end size of this breach is a bit larger tham the valve spring diameter.
In the described rotational fixation body helical groove is arranged, this groove topography size and valve spring are coincide mutually.
Described pressing plate is annular, and this annulus and set bolt rightabout one end are jagged, and the narrowest end size of this breach is a bit larger tham the valve stem diameter.
Described bolt center to pressing plate center and clamp base circle ring center apart from identical.
Have the pedestal locating hole on the annulus of described clamp base, the pin shaft hole position of leaving on pedestal locating hole and the rotational fixation body is corresponding.
The utlity model has following beneficial effect: owing to take such scheme, utilize the utility model to engine valve spring when carrying out assembly and disassembly, easy operating can be used for multiple vehicle, has avoided loaded down with trivial details mechanicalness to repeat operation, time saving and energy saving, the novel valve spring assembly tool that the utility model provides is simple and reasonable, cost is low, making is easy, and volume is little, in light weight, so be easy to carry, and avoided that cylinder cap is transported to the forcing press place and dismantled, be convenient to on-the-spot the use.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is vertical views of the present utility model;
Accompanying drawing 3 is A-A profiles of accompanying drawing 1.
1-pressing plate among the figure, 2-lead, 3-nut, 4-bolt, 5-clamp base, 6-rotational fixation body, 7-handle, 8-pedestal locating hole, 9-pin shaft hole.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing: by Fig. 1 in conjunction with Fig. 2, shown in Figure 3, this novel valve spring assembly tool comprises clamp base 5, clamp base 5 is annular, interior annulus is fluted, groove is built-in with two rotational fixation bodies 6, the fixedly connected handle 7 of clamp base 5 outer toroid one end, be convenient to hand-held operation, the fixedly connected bolt 4 of the other end, pressing plate 1 is passed on bolt 4 tops, there is hollow lead 2 upper end, hole that pressing plate 1 passes bolt 4, make the state of pressing plate 1 and clamp base 5 keeping parallelisms, there is nut 3 bolt 4 that is threaded lead 2 upper ends, rotation nut 2, pressing plate 1 compresses cotter seat, described clamp base 5 is annular, jagged with set bolt 4 relative ends, be convenient to the valve spring turnover, there are helical groove and valve spring to coincide mutually in the described rotational fixation body 6, the breach of described pressing plate 1 can pass valve stem and compress cotter seat, described bolt 4 centers to pressing plate 1 center and clamp base 5 circle ring center apart from identical, have pedestal on the annulus of described clamp base 5 and locate 8 holes, pin shaft hole 9 positions of leaving on pedestal locating hole 8 and the rotational fixation body 6 are corresponding, and bearing pin is pierced into fixing rotation fixed body 6 in two holes in correspondence.
Groove in the rotation fixed body 6 is attached on the valve spring, breach by clamp base 5 rotates in the annular groove of clamp base 5, clamp base 5 and valve spring are fixed, simultaneously pressing plate 1 is placed cotter seat top from the valve stem direction, screwing nut makes valve spring compress, or unscrew the compression that nut can discharge valve spring, thereby carry out the assembling of valve spring associated component.
By changing the valve spring of different rotation fixed body 6 corresponding different sizes, this assembly tool can adapt to different automobile types, and versatility is good.
Utilize the utility model to engine valve spring when carrying out assembly and disassembly, easy operating can be used for multiple vehicle, has avoided loaded down with trivial details mechanicalness to repeat operation.Can be onboard, also can be in operation under the car, one people is easily operation just, time saving and energy saving, because the novel valve spring assembly tool that the utility model provides is simple and reasonable, cost is low, making is easy, volume is little, in light weight, so be easy to carry, and avoided that cylinder cap is transported to the forcing press place and dismantled, be convenient to on-the-spot the use.
