Abstract
The utility model discloses a tool for disassembling an interference fitting pin. The tool comprises a bracket, a hydraulic hollow jack, a screw rod, a nut and a backing plate, wherein accommodating space which can accommodate the pin provided with a threaded hole is reserved in the bracket and allows the interference fitting pin to be disassembled and retreated, and an inlet allowing the pin provided with the threaded hole to enter the accommodating space is formed in the bottom of the bracket; a cylinder of the hydraulic hollow jack is vertically mounted on a top plate of the bracket, and the screw rod is vertically inserted into a hollow cavity; and the nut is assembled at one end of the screw rod, and the other end of the screw rod penetrates through the top plate of the bracket to enter the accommodating space and can be in threaded connection with the pin which is required to be disassembled and provided with the threaded hole. With the adoption of the scheme, disassembling work of the interference fitting pin provided with the threaded hole can be effectively completed, smaller space is occupied, and the tool is particularly suitable for occasions with limited space.
Description
Technical field
The utility model relates to the technical field of dismounting hinge pin, refers in particular to the dismounting hinge pin frock that a kind of interference connects.
Background technology
Interference connects is the interference fit of utilizing by between connection part, and directly connected piece being linked together to realize connects, and this connection claims again tight fit connection.In engineering machinery, a lot of occasions all will be used tight fit connection.The advantage of this connected mode is simple in structure, and bearing capacity is high, and the load that can withstand shocks is little to the strength reduction of axle, and can effectively avoid bearing pin excessive wear; Its shortcoming is assembling difficulty, higher to fit dimension required precision, and especially dismounting difficulty is safeguarded inconvenience, and the place less in space is more obvious.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, for the not easily detachable problem of the bearing pin that is threaded hole of interference fit, and the dismounting hinge pin frock that provides a kind of compact conformation, interference simple and reliable, easy to use to connect.
For achieving the above object, technical scheme provided by the utility model is: the dismounting hinge pin frock that a kind of interference connects, include support, hydraulic hollow jack, screw rod, nut, backing plate, wherein, in described support, be reserved with the accommodation space that can accommodatingly be threaded the bearing pin in hole, the dismounting hinge pin connecting for interference exits, and its bottom is provided with the inlet port that enters this accommodation space for bearing pin with threaded hole; The cylinder body of described hydraulic hollow jack is vertically loaded on the top board of support, is vertically fitted with screw rod in its hollow cavity; One end of described screw rod is equipped with nut, and its other end enters above-mentioned accommodation space through the top board of support, and can be threaded with the bearing pin that is threaded hole of need dismounting.
Between the top of described nut and hydraulic hollow jack, pad is useful on the backing plate of holding nut.
Compared with prior art, tool has the following advantages and beneficial effect the utility model:
1, frock leaves enough space and exits for bearing pin, without increasing cushion block to meet bearing pin length as traditional method, easy to use in drawing process (being unloading process);
2, tool structure is compact, simple and reliable, takes up room less, particularly applicable for the occasion of limited space;
Even 3 cantilever designs also, without using other frock that cantilever is fixed, can directly be used, use more convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of dismounting hinge pin frock dismounting interference fit bearing pin described in the utility model.
Fig. 2 is the exploded view of Fig. 1.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, dismounting hinge pin frock described in the present embodiment, it is mainly the bearing pin that is threaded hole for interference fit, it includes support 1, hydraulic hollow jack 2, screw rod 3, nut 4, backing plate 5, wherein, in described support 1, be reserved with the accommodation space of the bearing pin 6 that can accommodatingly be threaded hole, bearing pin 6 dismountings that connect for interference are exited, and its bottom is provided with the inlet port that enters this accommodation space for bearing pin 6 with threaded hole simultaneously, the cylinder body of described hydraulic hollow jack 2 is vertically loaded on the top board of support 1, is vertically fitted with screw rod 3 in its hollow cavity, one end of described screw rod 3 is equipped with a nut 4, and between this nut 4 and the top of hydraulic hollow jack 2, pad has backing plate 5, for holding nut 4, the other end of described screw rod 3 enters above-mentioned accommodation space through the top board of support 1, its bar footpath size matches with the screwed hole size of bearing pin, and can be threaded with the bearing pin that is threaded hole of need dismounting, as shown in FIG., bearing pin 6 is connected with connected piece 7 interference, screw rod 3 is threaded with the screwed hole of bearing pin 6, like this under the effect of hydraulic hollow jack 2, described screw rod 3 can enter the accommodation space in support 1 by drawing bearing pin 6, and then realize the dismounting of the bearing pin that interference connects.
After adopting above scheme, the utility model can effectively complete the dismantlement work of the bearing pin with threaded hole of interference connection, and it is less to take up room, occasion for limited space is particularly applicable, in drawing process (being unloading process) without increasing cushion block to meet bearing pin length as traditional method, even cantilever design also, without using other frock that cantilever is fixed, can directly be used, use more for convenience.This compared to existing technology, the utility model is a compact conformation, simple and reliable desirable dismounting hinge pin frock, is worthy to be popularized.
The examples of implementation of the above are only the preferred embodiment of the utility model, not with this, limit practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
