Abstract
The utility model discloses an easily-detached positioning pin, which relates to an easily-detached taper pin of an expansion lock and mainly solves problems that a taper pin for positioning is difficult to be pulled out due to deformation of a case type base of a motor after welding and thermal treatment, consequentially, time is wasted, labor intensity is large, work efficiency is low, and production cost of motors is high. The outer wall of a taper pin of the easily-detached positioning pin has conical degree, three to four axial grooves are arranged at the large end of the taper pin, a conical tube threaded hole is axially disposed inside the large end of the taper pin, a threaded hole is arranged at the bottom of the taper pin, threads which match with the axial conical tube threaded hole at the large end of the taper pin are arranged on a locking bolt, threads which match with the threaded hole at the bottom of the large end of the taper pin are arranged on a screw stem, and a conical hole with a trapezoidal section is disposed on a tightening nut. The large end of the taper pin of the easily-detached positioning pin can be tightened when the taper pin is detached after processing of a base, and the taper pin can be easily taken out, thereby greatly reducing labor intensity, improving work efficiency and decreasing cost.
Description
Technical field
The utility model relates to a kind of locating stud, relates to a kind of expansion specifically and locks quick detachable taper pin.
Background technique
At present, known common circular cone locating stud, all less than fluting, its shortcoming is the dismounting difficulty, in the field of employment that requires to dismantle, as the welding processing of the box support of motor, require before welding back, the heat treatment with taper pin location, locking, after heat treatment and the fine finishing, be incorporated with the winding stator before, require to extract taper pin.Owing to be with taper pin welding, heat treatment, therefore the stress owing to welding and heat treatment generation causes taper pin to be extruded distortion in the support production, extract difficulty, lose time, a taper pin all was difficult to extract in 4 hours sometimes, therefore delayed manufacturing schedule, labor intensity is big and work efficiency is low, cause motor cost of production height, manufacture cycle long, influence the punctual delivery of motor, limited the using scope of motor.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and the taper pin of a kind of expand locking and the easily detachable special construction that provide.
Technical solution of the present utility model is: quick detachable locating stud is by taper pin, and lock bolt tightens up nut and screw rod and forms;
1. the outer wall of taper pin has tapering, and the big end of taper pin has 3-4 axial groove, is provided with the taper pipe thread hole vertically in the big end of taper pin, and the bottom of the big end of taper pin is provided with tapped hole;
2. lock bolt be provided with the big end of taper pin in the axial screw thread that is complementary of taper pipe thread hole;
3. screw rod is provided with the screw thread that is complementary with the big bottom of taper pin portion tapped hole, tightens up nut and is provided with the cross section and is trapezoidal cone shape hole.
The diameter of the tapped hole of the big bottom of the taper pin described in the technical solution of the present utility model portion is less than the diameter in taper pipe thread hole axial in the big end of taper pin.
Use the utility model when motor cabinet machines back dismounting taper pin, earlier the lock bolt of taper pin end is back-outed, use instead then and tighten up nut and screw rod, earlier the big end of taper pin is tightened up, can easily taper pin be taken out, can reduce labor intensity greatly, save the production time, improve work efficiency, guarantee punctual delivery.

Embodiment
Shown in Fig. 1,2,3,4, the utility model by taper pin 1, lock bolt 2, tighten up nut 3 and screw rod 4 is formed, the outer wall of taper pin 1 has the tapering identical with the workpiece taper hole, the big end end of taper pin 1 has 3-4 axial grooves, be provided with axial bore in the taper pin 1 big end, have the taper pipe thread that swelling is used on the inwall of axial bore, the bottom of taper pin 1 big end inwall is provided with the dismounting tapped hole; Lock bolt 2 is provided with the tapered thread that is complementary with the interior axially taper pipe thread hole of taper pin 1 big end, when positioning and locking, taper pin 1 is inserted in the two workpiece pin-and-holes of locking to be positioned, then lock bolt 2 is screwed in the taper pipe thread hole on the taper pin 1, make the locking that is positioned of two workpiece, as shown in Figure 3; Screw rod 4 is provided with the screw thread that is complementary with taper pin 1 big bottom portion tapped hole, tighten up nut 3 and be provided with cone shape hole, the cross section of this cone shape hole is trapezoidal, when dismounting, lock bolt 2 is back-outed from taper pin 1, screw rod 4 is screwed in the tapped hole in the taper pin 1 big bottom portion, to tighten up nut 3 again is threaded in screw rod 4 and stretches out on the outer termination of workpiece, the cone shape hole that tightens up on the nut 3 is sleeved on the termination of taper pin 1, as shown in Figure 4, rotary tightening nut 3, owing to tighten up the effect in nut 3 upper conical holes, taper pin 1 slotted section drawn in, thereby taper pin 1 is extracted from workpiece like a cork.
