Description
Technical field
The present invention relates to a kind of fixture, particularly relate to a kind of light wall pipe clamping device.
Background technology
Pipe fitting makes part conventional in mechanical device, according to different needs, usually can hole to pipe fitting, the processing such as polishing or bending; Usually need man-hour to clamp it adding pipe fitting, what now usually adopt for the clamping of pipe fitting is scroll chuck or chuck, but to thinner pipe fitting, because the jaw of chuck and the outer wall of light wall pipe are point cantact or linear contact lay, so light wall pipe is easy to produce distortion under larger clamping force.
Summary of the invention
The invention is intended to provide a kind of light wall pipe clamping device, with the periphery making clamping force be evenly distributed on light wall pipe, thus make light wall pipe not yielding.
Base case light wall pipe clamping device of the present invention, comprises pedestal, disc spring, locating piece and gland; Described pedestal comprises mount pad and is fixedly connected on the sleeve pipe of mount pad upper end, and described inside pipe casing lower end is provided with disc spring baffle plate; Described disc spring is arranged in sleeve pipe, and is positioned at above disc spring baffle plate, described disc spring at least two, and is provided with annular retaining ring between adjacent disc spring; The center of described gland is provided with workpiece passing hole, and gland is threaded in the upper end of sleeve pipe; Described locating piece is connected to the upper end of mount pad, and locating piece is positioned at cannula center, and the upper end of locating piece is frustum.
In this base case, workpiece is inserted in sleeve pipe, workpiece contacts with the locating piece of lower end under gravity, and due to the upper end of locating piece be frustum, so a part for frustum upper end can be inserted in workpiece, thus workpiece is had to the effect of location, workpiece is put into after in sleeve pipe, rotate gland, gland can be made to move down relative to sleeve pipe, namely rotate gland and gland can be made to press down disc spring in sleeve pipe, and disc spring is subject to axial pressure will produce deformation, namely disc spring race diameter becomes large, and the diameter of inner ring diminishes, thus disc spring is by Workpiece clamping.And disc spring is when being subject to downward pressure, disc spring will have convex to become tabular, so during gland extruding upper end disc spring, the disc spring on upper strata will move down certain distance, simultaneously due to the frictional force between disc spring and workpiece, to make workpiece pre-tightening on locating piece, thus the accurate location to workpiece further.
In this programme, disc spring is Multi-layers distributing, and be provided with annular retaining ring between adjacent disc spring, each disc spring is separated, thus to workpiece, there is multiple clamping point, make to increase the clamping force of workpiece, and the frictional force between disc spring and workpiece also increases thereupon, make to the clamping effect of workpiece and locating effect better.Frustum is arranged in locating piece upper end in addition, and when workpiece presses down, locating piece also has the effect of tensioning to workpiece, thus improves the resistance to deformation intensity of workpiece.
Owing to adopting the internal diameter of disc spring to diminish light wall pipe clamping in this programme, thus clamping force is uniformly distributed in the circumference of light wall pipe, and circular arc itself has peptizaiton to power, thus make light wall pipe not yielding; Locating piece also has the effect of tensioning to workpiece simultaneously, thus improves the resistance to deformation intensity of workpiece, further can prevent the distortion of light wall pipe.
Preferred version one, as the further optimization to base case, the lower end of described locating piece is threaded with mount pad; Locating piece is threaded with mount pad, and the height of rotatable positioning seat to locating piece adjusts, thus adjustable is to the location of workpiece.
Preferred version two, as the further optimization to base case, described gland is provided with cannelure, described sleeve upper end extend in cannelure, and the screw thread that described gland coordinates with sleeve pipe is arranged in annular groove wall; Sleeve upper end is inserted in cannelure, iron filings can be prevented to be rolled in screw thread thus prevent gland and sleeve pipe from occurring stuck phenomenon.
Preferred version three, as the further optimization to base case, the upper end of described mount pad has some through holes; Adding man-hour to workpiece, having iron filings can enter in sleeve pipe unavoidably, then the some through holes on mount pad are conducive to clearing up iron filings.
Accompanying drawing explanation
Fig. 1 is the structural representation of light wall pipe clamping device embodiment.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: mount pad 11, sleeve pipe 12, disc spring 21, annular retaining ring 22, gland 23, locating piece 24, workpiece 24, cannelure 231.
Embodiment is substantially as shown in Figure 1: light wall pipe clamping device comprises pedestal, disc spring 21, locating piece 24 and gland 23.Pedestal comprises mount pad 11 and is fixedly connected on the sleeve pipe 12 of mount pad 11 upper end, inside, sleeve pipe 12 lower end is provided with disc spring 21 baffle plate, it is inner that disc spring 21 is arranged on sleeve pipe 12, and by disc spring 21 baffle limiting, disc spring 21 is provided with multiple, and multilayer is arranged, and be provided with annular retaining ring 22 between adjacent disc spring 21; The center of gland 23 is provided with workpiece 24 passing hole, is outside equipped with cannelure 231 in workpiece 24 passing hole, and sleeve pipe 12 tube wall is positioned at the cannelure 231 of gland 23, and sleeve pipe 12 and gland 23 are for being threaded.Locating piece 24 is arranged on the upper end of mount pad 11, and is positioned at sleeve pipe 12 center, and the upper end of locating piece 24 is frustum, and lower end is a threaded rod, and the threaded rod of locating piece 24 is threaded with mount pad 11.The upper mounting plate of mount pad 11 also has some through holes.
As shown in Figure 1, workpiece 24 is inserted in sleeve pipe 12, workpiece 24 contacts with the locating piece 24 of lower end under gravity, and due to the upper end of locating piece 24 be frustum, so a part for frustum upper end can be inserted in workpiece 24, thus workpiece 24 is had to the effect of location, workpiece 24 is put into after in sleeve pipe 12, rotate gland 23, gland 23 can be made to move down relative to sleeve pipe 12, namely rotating gland 23 can make gland 23 press down disc spring 21 in sleeve pipe 12, and disc spring 21 is subject to axial pressure will produce deformation, namely disc spring 21 race diameter becomes large, and the diameter of inner ring diminishes, thus workpiece 24 clamps by disc spring 21.And disc spring 21 is when being subject to downward pressure, disc spring 21 will have convex to become tabular, so when gland 23 extrudes upper end disc spring 21, the disc spring 21 on upper strata will move down certain distance, simultaneously due to the frictional force between disc spring 21 and workpiece 24, workpiece 24 will be made to hold out against on locating piece 24, thus the accurate location to workpiece 24 further.
In the present embodiment, gland 23 is provided with cannelure 231, makes sleeve pipe 12 upper end be inserted in cannelure 231, iron filings can be prevented to be rolled in screw thread thus prevent gland 23 and sleeve pipe 12 from occurring stuck phenomenon.Man-hour is being added to workpiece 24, is having iron filings can enter in sleeve pipe 12 unavoidably, then some through holes can be established on the upper mounting plate of mount pad 11 to be conducive to clearing up iron filings.
