Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of step shaft type device.
Background technology
In aviation hydraulic system, there is the pipe component of a lot of band mounting disc.During assembling, sealing ring is loaded in seal groove, be then connected on matrix with screw and pin, realize sealing and connection function.Due to its position and dimensional accuracy higher, the design of its device and processing just very crucial.And modal device adopts and changes terminal pad on lathe spindle and chuck, again make floral disc, after floral disc is connected with main shaft, then the car device designed in addition is contained on floral disc by interference fit and bolted pattern.The shortcoming of the program is: 1, fabrication cycle is long.2, repeatedly dismantle, spindle coupling disc is installed, the dimensional accuracy of main shaft and terminal pad can be reduced, affect the machining accuracy of follow-up conventional axial workpiece.3, because lathe model is different, the interface pattern of main shaft and terminal pad and size can be different, cause the physical dimension of floral disc and pattern also can be different.Therefore, how to overcome the shortcoming that above device exists, realize quick-clamping, location on lathe, and be connected on different lathes fast by conventional connected mode, realize interchangeability, thus enhance productivity, this is that the difficult problem that must first solve produced by this type of part.
Utility model content
The purpose of this utility model is to provide that a kind of interchangeability is strong, and the manufacturing cycle is short, and can on lathe quick-clamping, location, improve the step shaft type device of crudy and production efficiency.
A kind of step shaft type device, mainly comprises Jia Tai, lower folder platform, mounting groove, packing ring, bolt group, pin group composition.Upper folder platform becomes cylindrical-shaped structure, is arranged on whole device topmost, is fixed on machine chuck.Lower folder platform also becomes cylindrical-shaped structure, forms Step Shaft with upper folder platform.Mounting groove becomes U-shaped vibrational power flow in lower Jia Tai centre position.For installing workpiece to be added.Workpiece top to be added is arranged in mounting groove, and bottom is arranged on lower folder platform tail end, and being interlocked with described lower folder platform is formed.Bolt group is made up of 2 bolts; Pin group is made up of 2 pins; Described bolt group and pin group are arranged in a crossed manner in lower folder platform lower edge relevant position between two.Packing ring is positioned at above bolt, below workpiece to be added, is mainly used in workpiece to be added to assist fastening.
The utility model step shaft type car device manufacture and the process-cycle short, directly clamped by machine chuck and press from both sides platform, realizing different model lathe all can to the utility model step shaft type car device quick-clamping.Can each size and positional precision be ensured, compact conformation.Product processing quality is reliable, and production efficiency improves greatly.Can on dissimilar lathe clamping and do not need to increase other device, interchangeability is strong.Be applicable to very much the needs of batch production.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model step shaft type car device.
Fig. 2 is the utility model workpiece mounting structure to be added schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of step shaft type device as shown in Figure 1 and Figure 2, mainly comprises folder platform 1, lower folder platform 2, mounting groove 3, packing ring 5, bolt group 6, pin group 7 forms.Upper folder platform 1 one-tenth cylindrical-shaped structure, is arranged on whole device topmost, is fixed on machine chuck.Lower folder platform 2 also becomes cylindrical-shaped structure, forms Step Shaft with upper folder platform 1.Mounting groove 3 one-tenth U-shaped vibrational power flow is in lower folder platform 2 centre position.For installing workpiece 4 to be added.Workpiece 4 top to be added is arranged in mounting groove 3, and bottom is arranged on lower folder platform 2 tail end, and being interlocked with described lower folder platform 2 is formed.Bolt group 6 is made up of 2 bolts; Pin group 7 is made up of 2 pins; Described bolt group 6 is arranged in a crossed manner in lower folder platform 2 lower edge relevant position between two with pin group 7.Packing ring 5 is positioned at above bolt, below workpiece 4 to be added, is mainly used in workpiece to be added to assist fastening.
During work: first upper folder platform 1, lower folder platform 2 are carried out Excircle machining, ensure its axiality, thus ensure that workpiece 4 to be added is adding the precision in man-hour.Hole on workpiece 4 to be added is loaded pin, then by bolt and packing ring by Workpiece clamping to be added, get final product work.
The utility model step shaft type device manufacture and the process-cycle short, directly clamped by machine chuck and press from both sides platform, realizing different model lathe all can to the utility model step shaft type device quick-clamping.Can each size and positional precision be ensured, compact conformation.Product processing quality is reliable, and production efficiency improves greatly.Can on dissimilar lathe clamping and do not need to increase other device, interchangeability is strong.Be applicable to very much the needs of batch production.
