Abstract
The invention relates to a universal screwing tool capable of achieving multi-size exchangeability, in particular to the screwing tool for screwing nuts and pistons, pistons and piston rods, and guide sleeves and cylinder bodies. The universal screwing tool is mainly applicable to screwing between cylinder pistons and piston rods of various hydraulic cylinders or screwing between guide sleeves and cylinder bodies of the hydraulic cylinders, and comprises a square shaft, a threaded pin and a pitch plate. The square shaft and the pitch plate are in rigid connection, and the threaded pin and the pitch plate are connected through threads. The threaded pin is matched with pin shafts of various diameters, proper threaded shafts are selected according to the hole sizes in the using process, and then the threaded shafts are installed in proper threaded holes according to the sizes of hole reference circles. Multiple special tools are integrated to one universal tool, so that the production cost is reduced, the universality of the tool is improved, use efficiency is improved, and the tool is convenient to manage.
Description
Technical field
The present invention devises the universal screwing tool of a kind of many size exchangeabilities, specifically a kind of for fastening nut and piston, piston and piston rod, fairlead and cylinder body.Mainly be applicable to tightening between all kinds of hydraulic cylinder piston and piston rod or between fairlead and cylinder body.
Background technology
At present, machinery industry hydraulic jack fastening nut and piston, piston and piston rod, fairlead and cylinder body assemble when tightening usually needs a screwing tool could use torque spanner that piston is fastening.Traditional screwing tool makes a kind of screwing tool according to each hole reference circle specialized designs usually, only be suitable for the assembling of the piston of a kind of hole reference circle, nut, fairlead, cause the model of professional tooling many, quantity is large, inconvenience management, use and easily obscure, cost of manufacture is high, and some frocks just use a utilization rate low; As when in use locating shaft fractures, whole frock is cancelled, and has to again make.In order to improve oil cylinder service life and performance, ensureing the impact of oil cylinder safety and reliability, improving efficiency of assembling, effectively prevent the thread failures such as thread looseness seepage to be badly in need of a kind of novel frock of design.
Summary of the invention
The object of the invention is to make up above-mentioned deficiency, provide design a kind of compact conformation, easy to process, interchangeability is strong, the universal screwing tool of many sizes.
Technical scheme of the present invention is: this invention is the universal screwing tool of a kind of many size exchangeabilities, comprises square shaft, threaded, pitch plate.Square shaft and pitch plate are rigidly connected, threaded and pitch plate are threaded connection, threaded is furnished with the bearing pin of multiple diameter, use and select suitable thread spindle according to the size in hole, being then arranged in suitable screwed hole according to large young pathbreaker's thread spindle of hole reference circle, being synthesized to a kind of universal frock by overlapping special tooling more, save production cost, improve the versatility of frock, improve service efficiency, reach the object of convenient management.
Compared with existing product, not only saved production cost, structure is simple, processing, easy for installation, strong adaptability, improves service efficiency, convenient management.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, implementation method is described
The universal screwing tool structural representation of the many size exchangeabilities of Fig. 1.
Square shaft 1 threaded 2 pitch plate 3
specific implementation method
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1, the present invention mainly comprises square shaft 1, threaded 2, pitch plate 3.Square shaft 1 and pitch plate 3 are rigidly connected, threaded 2 and pitch plate 3 are threaded connection, threaded 2 is furnished with the bearing pin of multiple diameter, uses and selects suitable thread spindle 2 according to the size in hole, is then arranged in suitable screwed hole according to large young pathbreaker's thread spindle 2 of hole reference circle.Select the position of different pitch hole A according to actual needs, the threaded of different size, can be combined into the screwing tool that many sizes are universal.Strengthen many specifications versatility of product, save production cost, improve service efficiency, convenient management.
