Abstract
The utility model discloses a combined threaded connection device for electroplating of piston rods, which comprises a joint. External threads are arranged at the upper end of the joint, an inserting hole and a threaded hole are arranged at the lower end of the joint, the end of a piston rod is inserted into the inserting hole and the threaded hole and connected with the inserting hole and the threaded hole in a threaded manner, the threaded hole is in the shape of three steps the diameter of the threaded hole is sequentially increased from top to bottom, the maximum diameter of the threaded hole is smaller than the diameter of the inserting hole, and the threaded hole and the inserting hole are coaxial. The combined threaded connection device is in the shape of three steps, not only can guarantee a threaded structure, fine electroplating conductive contact of the piston rod and quality of processed products, but also is applicable to electroplating piston rods in various threaded structures, and omits replacement of a conducting device for electroplating the piston rods in various threaded structures, electroplating production is realized on an automatic production line, manufacturing cost of a tooling is reduced, time and labor are saved, production efficiency is improved, and the combined threaded connection device is fine in universality and more convenient in both installation and detachment.
Description
Technical field
The coupling device that the utility model relates to a kind of piston rod when electroplating frock relates in particular to a kind of combined live stopper rod and electroplates screw connection.
Background technology
Add man-hour in the plating of vehicular shock absorber component of rod category, it is to utilize its screw connection conduction that its piston rod is electroplated frock, because the piston rod thread of different varieties varies in size, the length difference needs to design the different conductive contact of many covers and realize electroplating.When large-scale production because the piston rod Electroplating Production is switched frequent.The different conductive contact of many covers must be changed back and forth, not only takes a lot of work but also time-consuming, also spends a large amount of processing charges owing to need to make many set of connection devices, does not also have a cover to electroplate screw connection now and can solve this technical problem.
Summary of the invention
The purpose of this utility model just is that providing a kind of addresses the above problem, and the saving of labor saves time again, enhances productivity, and greatly reduces cost of manufacture again simultaneously, and versatility is good, installs, dismantles all the screw connection of combined live stopper rod plating comparatively easily.
To achieve these goals, the technical solution adopted in the utility model is: a kind of combined live stopper rod is electroplated screw connection, comprise joint, upper end of joint is provided with outside screw, the lower end is provided with patchhole and the threaded hole that inserts and be threaded for the piston rod end, described threaded hole be three grades step-like, and diameter from top to bottom increases successively, the maximum diameter of described threaded hole is less than the diameter of patchhole, and threaded hole and the coaxial setting of patchhole.
As preferably: three grades of steps of described threaded hole are that the piston rod thread of M8, M10, M12 cooperates with diameter respectively.
As preferably: described joint and the coaxial setting of threaded hole.
Compared with prior art, advantage of the present utility model is: utilize three kinds of screw thread various outer diameters of piston rod size, in conjunction with screw thread length, be designed to three layers step-like, both can guarantee helicitic texture, the contact of piston rod plated conductive is good, quality product after guaranteeing to process, the piston rod that can adapt to multiple helicitic texture is again electroplated, and the diameter of three layers of step of threaded hole increases from top to bottom successively, can connect three kinds of piston rods easily, can not influence each other.
This device solves the piston rod of multiple helicitic texture electroplate and need not change electric installation, in the enterprising electroplating production of automatic production line, and reduced the manufacturing cost of frock, not only saving of labor but also save time enhanced productivity, and greatly reduced cost of manufacture simultaneously again, use this device versatility good, it is all comparatively convenient to install, dismantle, and effect is remarkable, has to promote practical value widely.
Description of drawings
Fig. 1 is the utility model prior art constructions synoptic diagram;
Fig. 2 is a structural representation of the present utility model.
Among the figure: 1, joint; 2, patchhole; 3, threaded hole.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1: referring to Fig. 1, Fig. 2, a kind of combined live stopper rod is electroplated screw connection, comprise joint 1, joint 1 upper end is provided with outside screw, the lower end is provided with patchhole 2 and the threaded hole 3 that inserts and be threaded for the piston rod end, described threaded hole 3 be three grades step-like, and diameter from top to bottom increases successively, the maximum diameter of described threaded hole 3 is less than the diameter of patchhole 2, and threaded hole 3 and patchhole 2 coaxial settings, three grades of steps of described threaded hole 3 are M8 with diameter respectively, M10, the piston rod thread of M12 cooperates, described joint 1 and threaded hole 3 coaxial settings.
Be M8 to diameter, M10, when the piston rod of M12 is electroplated, itself and corresponding threaded hole 3 be threaded get final product, the maximum diameter of threaded hole 3 is less than the diameter of patchhole 2, make patchhole 2 can hold the piston rod of three kinds of diameters, be designed to three layers step-like, both can guarantee helicitic texture, the contact of piston rod plated conductive is good, quality product after guaranteeing to process, the piston rod that can adapt to multiple helicitic texture is again electroplated, this device solves the piston rod of multiple helicitic texture electroplate and need not change electric installation, in the enterprising electroplating production of automatic production line, and reduced the manufacturing cost of frock, not only saving of labor but also save time enhanced productivity, and greatly reduced cost of manufacture simultaneously again, use this device versatility good, install, it is all comparatively convenient to dismantle.
