Abstract
The invention relates to a positioning connecting pin. The positioning connecting pin particularly comprises a main pin shaft (1), a washer (3) and a nut (4). The main pin shaft (1) is sequentially provided with a flange (7), a cylindrical shaft section (8), a conical shaft section (9) and a threaded section (10). The main pin shaft (1) further comprises a cylindrical pin sleeve (2) which is provided with a conical inner hole (12) and a radial open groove (13). The cylindrical pin sleeve (2) is installed on the conical shaft section (9) of the main pin shaft (1) in a matched and sleeving mode. The washer (3) and the nut (4) are installed on the threaded section (10). According to the positioning connecting pin, different from a common connecting structure of a cylindrical pin and a conical pin, the conical shaft section (9) of the main pin shaft (1) of the positioning connecting pin is used cooperatively with the conical inner hole (12) of the cylindrical pin sleeve (2) so that connecting can be greatly facilitated, the manufacturing requirements of connected pieces are lowered, and the assembling efficiency and reliability are improved.
Description
Technical field
The present invention relates to a kind of connecting pin, especially relate to a kind of connecting pin for positioning.
Background technology
General connecting pin for positioning adopts straight pin or taper bolt to realize, and while there is assembling, on two connected pieces, pin-and-hole is difficult to accurate contraposition, the borehole accuracy of connected piece is required higher, and manufacturing cost is high, assemble consuming time, poor operability.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of borehole accuracy to connected piece and requires low, easy accessibility, can being dismounted for multiple times, and the connecting pin for positioning that efficiency is high, security is good.
In order to solve the problems of the technologies described above, the invention provides a kind of connecting pin for positioning, comprise stub axle, packing ring and nut, described stub axle has flange, cylinder shaft part, circular cone shaft part, thread segment successively, also comprise a cylinder guide, described straight pin cover has tapered bore and is provided with a radial opening groove, and described cylinder guide engage sleeves is contained on the circular cone shaft part of described stub axle, and described packing ring and nut are arranged on described thread segment.
As a modification of the present invention, on described flange, be provided with away from one end of described cylinder shaft part the charging crane of being convenient to handling instrument clamping.
Preferably, described charging crane is turret head, four angle heads, interior four jiaos of grooves or interior hexagonal groove.
As another kind of improvement of the present invention, described thread segment is provided with pin-and-hole and pin.
Preferably, described pin is split pin.
Adopt the connecting pin for positioning of technique scheme, because stub axle is provided with circular cone shaft part, straight pin cover has tapered bore and is provided with a radial opening groove, the tapered bore engage sleeves of cylinder guide is contained on the circular cone shaft part of stub axle, the present invention is different from conventional straight pin and is connected with taper bolt, the circular cone shaft part of its stub axle coordinates the tapered bore of cylinder guide to use can facilitate connection widely, reduces the manufacture requirement to connected piece, improves efficiency of assembling and reliability. Radial opening groove is used for connecting when fastening and swells, and makes in its hole that is locked at connected piece. Stub axle its flange after assembling locking is close at the end face of connected piece realizes stop bit, and the other end utilizes packing ring to be close in the other end of connected piece and realizes stop bit.
In sum, the present invention is that a kind of borehole accuracy to connected piece requires low, easy accessibility, can being dismounted for multiple times, and the connecting pin for positioning that efficiency is high, security is good.
Brief description of the drawings
Figure l is the stub axle construction schematic diagram in a kind of connecting pin for positioning of the present invention;
Fig. 2 is the opening taper pin nested structure schematic diagram in a kind of connecting pin for positioning of the present invention;
Fig. 3 is the explosive view of a kind of connecting pin for positioning of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Referring to figure l, Fig. 2 and Fig. 3, stub axle l is provided with flange 7, cylinder shaft part 8, circular cone shaft part 9, thread segment 10 according to this, on flange 7, be provided with away from one end of cylinder shaft part 8 turret head 6 of being convenient to handling instrument clamping, thread segment 10 is provided with pin-and-hole 11 and split pin 5, also comprise a cylinder guide 2, cylinder guide 2 has tapered bore and is provided with a radial opening groove 13, tapered bore 12 engage sleeves of cylinder guide 2 are contained on the circular cone shaft part 9 of stub axle l, and packing ring 3 and nut 4 are arranged on thread segment 10 and split pin 5 coordinates pin-and-hole 11 to lock.
Turret head 6 also can replace by four angle heads, interior four jiaos of grooves or interior hexagonal groove.
Referring to figure l, Fig. 2 and Fig. 3, after the installing hole of the first connector 15 and the second connector 14 aligns, threaded section of 10 one end of stub axle l are stretched into from the first connector 15 1 sides, and stretch out thread segment 10 from the second connector 14 of opposite side, then cylinder guide 2 is inserted in to the thread segment 10 stretching out, in this process, the first connector 15 and the second connector 14 are without Accurate align, as long as the little head part in stub axle l tapering enters the second connector 14. Subsequently packing ring 3 and nut 4 are inserted on the thread segment 10 of the stub axle l exposing and locking, in locking process, stub axle l is by automatic alignment the first connector 15 and the second connector 14. Split pin 5 is finally inserted in the pin-and-hole 11 on stub axle l, realizes locking thread, ensures safety. Be convenient to load and unload fast and prevent that stub axle l from rotating with the turret head 6 of handling instrument clamping.
