Problems solved by technology

[0002] A large number of positioning pins need to be pulled out during the mechanical maintenance of the generator set. The pin puller is a tool commonly used in maintenance work. The impact pin puller is commonly used, or pulled out by knocking out. The positioning pin itself It is a precision component, and the impact and knocking method will reduce its accuracy after being pulled out many times, affecting the normal operation of the unit and posing a safety hazard

Embodiment Construction

[0022] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the present invention.

[0023] Such as Figure 1-6 Shown:

[0024] A rotary pin pulling device, comprising a base 10, a threaded pulling rod 20 and a rotating nut 30, a through hole with a circular cross-section is opened in the center of the base 10, the threaded pulling rod 20 is penetrated in the through hole, and the rotating nut 30 It is sleeved on the threaded rod 20 and abuts against the end surface of the base 10 . The threaded rod 20 is provided with a connection end, which is used for connecting with the connector 40 , and the connector 40 is used for connecting with the positioning pin.

[0025] The threaded puller 20 passes through the through hole...

Abstract

The invention discloses a rotary type pull pin device. The rotary type pull pin device comprises a base, a threaded pull rod and a rotary nut, wherein a through hole with a circular section is formedin the middle of the base; the threaded pull rod is arranged in the through hole in a penetrating mode; the rotary nut is sleeve connection on the threaded pull rod, and abuts against the end surfaceof the base; a connecting end which is connected to a connecting head is arranged on the threaded pull rod; the connecting head is used for connecting a dowel pin; the rotary nut drives the threaded pull rod to pull; and continuous rotation of the rotary nut is converted into upward movement of the threaded pull rod. The rotary type pull pin device can precisely control pull-out rhythm, is uniformin applying force, reduces abrasion on the dowel pin, and guarantees safe operation of a unit.

Description

technical field [0001] The invention relates to the field of maintenance, in particular to a rotary pin pulling device. Background technique [0002] A large number of positioning pins need to be pulled out during the mechanical maintenance of the generator set. The pin puller is a tool commonly used in maintenance work. The impact pin puller is commonly used, or pulled out by knocking out. The positioning pin itself It is a precision part, and the way of impact and knocking leads to the reduction of its precision after being pulled out many times, which affects the normal operation of the unit and poses a safety hazard. Contents of the invention [0003] The object of the present invention is to provide a rotary pin pulling device to solve the above problems. [0004] In order to achieve the purpose of the present invention, the technical solution adopted is a rotary pin pulling device, including a base, a threaded puller rod and a rotating nut, a through hole with a cir...
