Abstract
The utility model discloses a kind of positioners for screw thread process, including rack, one end of rack is along workpiece axial direction geometrical clamp bar I, above the other end baseline rod is axially connected with along workpiece, baseline rod is socketed hydraulic cylinder in one end away from clamping bar I, and the piston rod of hydraulic cylinder is stretched out to the one side of clamping bar I, and clamping bar II is fixed in the end of piston rod, position between two clamping bars is processing stations, and the lateral ends of clamping bar I and clamping bar II are cusp-shaped.Hydraulic cylinder is equipped with screw, and hydraulic cylinder can be fixed on baseline rod by screw.The positioner of the utility model clamps workpiece using two clamping bars, and adapt to the clamping of different workpieces by adjusting position of the hydraulic cylinder on baseline rod, compared with prior art, the precision height of the utility model positioning processing, uniformity are high, and positioning device structure is simple, it is highly practical.
Description
Technical field
The utility model is related to machining equipment fields, and in particular to a kind of positioning for tubular workpiece screw thread process
Device.
Background technology
At present, it is higher to the quality, performance and appearance requirement of tubular workpiece, the operation of the external screw thread processing of tubular workpiece
For platform as shown in Fig. 2, 7 be cylindrical die roll I, 8 be cylindrical die roll II, and during screw thread process, tubular workpiece is pushed to I 7 He of cylindrical die roll manually
The centre of cylindrical die roll II 8 processes screw thread.The mode poor accuracy of this manual push processing, the uniformity of the workpiece after processing
It is poor.
The content of the invention
The technical problem to be solved by the present invention is to provide the screw thread process that a kind of accuracy is high, uniformity is high to position dress
It puts, to solve the above problems, the utility model provides a kind of positioner for screw thread process.
The purpose of this utility model is realized in the following manner：
A kind of positioner for screw thread process, including rack 1, one end of rack 1 along workpiece axial direction geometrical clamp bar I 4,
Baseline rod 2 is axially connected with above the other end along workpiece, baseline rod 2 is socketed hydraulic cylinder 3, hydraulic cylinder in one end away from clamping bar I 4
3 piston rod is stretched out to the one side of clamping bar I 4, the end fixation clamping bar II 5 of piston rod, and the position between two clamping bars is processing
The lateral ends of station, clamping bar I 4 and clamping bar II 5 are cusp-shaped.
The hydraulic cylinder 3 can slide on baseline rod 2, and baseline rod 2 is equipped with screw 6, and screw 6 can fix hydraulic cylinder 3
On baseline rod 2.
The beneficial effects of the utility model：The positioner of the utility model clamps workpiece using two clamping bars,
And the clamping of different workpieces is adapted to by adjusting position of the hydraulic cylinder on baseline rod, compared with prior art, this practicality is new
The precision height of type positioning processing, uniformity are high, and positioning device structure is simple, highly practical.
Description of the drawings
Fig. 1 is the front view of the utility model structure.
Fig. 2 is the top view of screw thread process operation console.
Wherein, 1 is rack；2 be baseline rod；3 be hydraulic cylinder；4 be clamping bar I；5 be clamping bar II；6 be screw；7 be cylindrical die roll
Ⅰ；8 be cylindrical die roll II.
Specific embodiment
1, attached drawing 2 and specific embodiment are described in further detail the utility model below in conjunction with the accompanying drawings, should manage
Solution, specific embodiment described herein are only used to explain the utility model, are not used to limit the utility model.
As shown in Figure 1, a kind of positioner for screw thread process, including rack 1, one end of rack 1 is axial along workpiece
Fixed clamping bar I 4, other end top are axially connected with baseline rod 2 along workpiece, and baseline rod 2 is socketed liquid in one end away from clamping bar I 4
Cylinder pressure 3, the piston rod of hydraulic cylinder 3 are stretched out to the one side of clamping bar I 4, the end fixation clamping bar II 5 of piston rod, between two clamping bars
Position for processing stations, the lateral ends of clamping bar I 4 and clamping bar II 5 are cusp-shaped.
Preferably, hydraulic cylinder 3 is equipped with screw 6, and hydraulic cylinder 3 can be fixed on baseline rod 2 by screw 6.It in this way, both can be with
It realizes fixation of the hydraulic cylinder 3 on baseline rod 2, and then preferably fixes workpiece, and can hydraulic pressure be adjusted by active screw 6
Position of the cylinder 3 on baseline rod 2, to adapt to the clamping position of different dimension workpieces.
The course of work of the utility model is as follows：The positioner of Fig. 1 is mounted on cylindrical die roll I 7 in Fig. 2 operation consoles first
With cylindrical die roll II 8 it is central axial on, adjusting screw 6 allows hydraulic cylinder 3 movable on baseline rod 2, then adjusts hydraulic cylinder 3
Position on baseline rod 2 to adapt to the clamping of different dimension workpieces, by workpiece to be processed be placed on clamping bar I 4 and clamping bar II 5 it
Between, hydraulic cylinder 3 is adjusted so that II 5 top tight workpiece of clamping bar, then fixing screws 6 and then hydraulic cylinder 3 is fixed on baseline rod 2.
Start cylindrical die roll, screw thread process is carried out to workpiece.
Above-described is only the preferred embodiment of the utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, several changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model, these all do not interfere with the effect and practical applicability of the utility model implementation.
