Abstract
The utility model relates to a compression spring installation tool and especially relates to a special compression spring preload installation clamp. A special compression spring preload installation clamp comprises a center rod, a power-assisting nut and a jacket. The center rod is a screw with a handheld base. An external diameter of the base is greater than the external diameter of the compression spring. The power-assisting nut matches with the screw. The jacket is a two-piece semi-cylinder hollow mechanism. The compressed compression spring can be accommodated in the hollow cylinder which is formed by two pieces of the semi-cylinders. Two ends of the hollow cylinder are provided with openings. An aperture is slightly greater than the external diameter of the screw. The utility model provides the special compression spring preload installation clamp whose structure is simple and operation is easy. By using the clamp, a bending problem during compression spring installation can be effectively solved. Installation quality and installation efficiency are increased.
Description
Technical field
The utility model relates to a kind of compression spring erecting tools, relates in particular to a kind of special-purpose compression spring pretension sectional fixture.
Background technology
The normality height of compression spring is higher than working depth, need compress the spring into working depth during installation.The manual compression spring is not only required great effort, and the spring behind the pressurized receives side force easily and produce bending, influences installation effectiveness.When especially needing the installing and locating pin, compression quality and the degree direct influence installation effectiveness and the effect of compression spring.
Summary of the invention
The purpose of the utility model provides a kind of special use simple in structure, easy operating and compresses spring pretension sectional fixture, effectively solves the buckling problem in the installation of compression spring, raising installation quality and installation effectiveness.
In order to realize above-mentioned purpose, the utility model solves the problems of the technologies described above through following technical proposals:
A kind of special-purpose compression spring pretension sectional fixture comprises center-pole, power-assisted nut, chuck, and described center-pole is to have the screw rod of holding pedestal, and susceptor diameter is greater than compression spring external diameter; Said power-assisted nut and screw rod are complementary; Said chuck is two hollow mechanisms of semicylinder, and two cooperate the compression spring after the hollow cylinder inside of forming can hold pressurized, the perforate of hollow cylinder two ends, and the aperture is slightly larger than the screw rod external diameter.
As further improvement, above-mentioned center-pole base-plates surface carries out anti-skidding processing.
As further improvement, above-mentioned center-pole is not provided with screw thread near holding base end, and the length that is not provided with the threaded portion is no more than the active length of compression spring.
As further improvement, above-mentioned power-assisted nut both sides increase the power-assisted thin plate.
The beneficial effect of the utility model is; Spring is compressed in mating reaction through center-pole and power-assisted nut; Fixation through chuck obtains the compression spring under the duty again; Simple in structure, easy and simple to handle, can effectively solve the buckling problem in the installation of compression spring, improve installation quality and installation effectiveness.
Description of drawings
The assembling sketch map A of Fig. 1 the utility model.
The assembling sketch map B of Fig. 2 the utility model.
The specific embodiment
Below in conjunction with accompanying drawing; The utility model is described in further detail: the assembling sketch map A of a kind of special-purpose compression spring pretension sectional fixture as shown in Figure 1; These anchor clamps comprise center-pole 1, power-assisted nut 2, chuck 3; Compression spring 4 penetrates from the screw rod end of center-pole 1, and power-assisted nut 2 is installed, and the screw movement through power-assisted nut 2 can carry out the pretension compression with spring 4.
As shown in Figure 2; Behind compression spring 4 pretensions, it is fixing that two chucks 3 are packed into from spring 4 both sides, the power-assisted of back-outing again nut 2; Dress compression spring 4 takes out from center-pole 1 together with two chucks 3; The compression spring 4 that this has just obtained duty puts it to compression spring 4 installation sites, opens chuck 3 and accomplishes installation.
