Abstract

The utility model discloses an adjustable positioning sleeve in a hydraulic power clamp, which comprises a hollow threaded sleeve with one end extending into a pull rod. The other end of the threaded sleeve is connected on a dust cap of a chuck, and a septal surface of the chuck serves as the datum reference lengthwise; thread is arranged on two sides of the hollow threaded sleeve; one end of the hollow threaded sleeve is connected and welded with the dust cap while the other end thereof is threaded with an adjusting head; and the thread is provided with adhesive. A lock nut is screwed on a hexagon screw which can be locked with the hollow threaded sleeve; and a positioning screw is screwed on the hexagon screw. A seal ring is clamped inside a sealing groove of the adjusting head for seal, and the length of a rod can be adjusted through loosening the lock nut and adjusting the hexagon screw. The utility model has the advantages of simple and reliable structure of the adjustable positioning sleeve, rods with different lengths can be adjusted conveniently, and the assembly and disassembly becomes more convenient, thereby reducing the labor intensity of operating personnel, shortening the auxiliary time of part processing, and improving the work efficiency.

Description

Adjustable whole positioning sleeve in the hydraulic power anchor clamps
Technical field
The utility model relates to a kind of frock, particularly a kind of adjustable whole positioning sleeve that is used for the hydraulic power anchor clamps.
Background technology
The hydraulic power anchor clamps are when carrying out clamping to bar, and the amount of overhanging of bar is not easy to be adjusted to suitable position, and the positioning device structure complexity that is used for adjusting, and adjust inconvenience.
The utility model content
The purpose of this utility model provides a kind of simple in structure, the adjustable whole positioning sleeve that is used for the hydraulic power anchor clamps easy to adjust.
Adjustable whole positioning sleeve in the hydraulic power anchor clamps described in the utility model, hexagonal screw rod, locking nut, adjustment head, sealing ring, dog screw and hollow swivel nut in comprising; One end of described hollow swivel nut stretches in the pull bar, adjusts head and is installed in its end, and the other end of hollow swivel nut is connected on the dust cap of chuck, and with the septal surface of the chuck location benchmark as length direction; One end of interior hexagonal screw rod is fixed on by screw thread and adjusts in the centre bore, and the other end is screwed into locking nut, and locking nut is interior hexagonal screw rod and the locking of hollow swivel nut; On the endoporus of hexagonal spiral shell, sealing ring was stuck in the seal groove of adjusting an outer rim in dog screw was screwed in.
Can also be provided with on the hollow swivel nut one with chuck on the positioning round orifice of screw fit, prevent hollow swivel nut axial float.
The utility model is adjusted interior hexagonal screw rod, thereby bar length is regulated by unclamping locking nut.It is simple in structure, reliable, for different bar length, can regulate easily, installs and removes convenient; Thereby alleviated labor intensity of operating personnel, shortened the non-cutting time of part processing, improved operating efficiency.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, adjustable whole positioning sleeve in the hydraulic power anchor clamps comprises interior hexagonal screw rod 2, locking nut 3 adjusts 4, sealing ring 5, dog screw 6, hollow swivel nut 7, hollow swivel nut 7 one ends stretch in the pull bar 8, and the other end is connected on the dust cap 10 of chuck 9, link together by dust cap 10 and chuck 9, and with the septal surface of the chuck 9 location benchmark as length direction; One end of pull bar 8 stretches in the oil cylinder 1, and hollow swivel nut 7 is because length is longer, and processing is inconvenient, so endoporus adopts the ladder form, shortens processing length.One setting circle hole is arranged on the hollow swivel nut 7, be used for chuck 9 on screw fit, prevent hollow swivel nut 7 axial floats.All there is screw thread at the two ends of hollow swivel nut 7, and an end is threaded with dust cap 10 and welds, the other end with adjust 4 and be threaded and screw thread need be with glue.Adjusting 4 is made up of interior hexagonal screw rod 2, locking nut 3, dog screw 6; In being screwed in, locking nut 3 on the hexagonal screw rod 2, can lock interior hexagonal screw rod 2 and hollow swivel nut 7; Dog screw 6 is screwed on the interior hexagonal screw rod 2.Sealing ring 5 is stuck in the seal groove of adjusting 4 outer rim, seals.By unclamping locking nut 3, hexagonal screw rod 2 in adjusting, thus bar length is regulated.
The utility model provides a kind of thinking and method that is used for the adjustable whole positioning sleeve of hydraulic power anchor clamps; what approach of the method for this technical scheme of specific implementation is a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
