Abstract
The invention belongs to the manufacturing field of a mechanical assembly and relates to a wrench. The wrench is a recombination tool which can realize alignment and location through threaded connection, and location and compaction. The wrench is convenient to process and assemble, and thus the disadvantage in a traditional structure that a special part has a special purpose can be overcome, and the problem that a tightened capstan nut is difficult to remove can be solved, and the production cost is also reduced. According to the wrench, a lever arm (1), a locating sleeve (2), a tightening ring (3), a pin bolt (4) and a connecting plate (5) are integrally combined, and the connecting plate and the pin bolt can be exchanged as needed, and thus the production cost is reduced; besides the wrench plays an important role to quickly remove various tightening capstan nuts.
Description
Technical field
The invention belongs to Automatic manual transmission and manufacture field, relate to a kind of spanner.
Background technology
Existing spanner is generally integral type processing welding, spanner is in use easy to wear, wherein pin for suppressing metal is not replaceable, consumable accessory interchangeability is poor, when using simultaneously, in not rotatable location, tightening capstan nut outer ring, because rotation torque is large during assembling, easily cause spanner landing and cause the generation of casualty accident.
Summary of the invention
The object of the invention: provide a kind of centering accurate positioning, install fast and reliable, cost is low, can be convenient to the spanner exchanged.
Technical scheme of the present invention is: a kind of spanner, comprise lever arm 1, positioning sleeve 2, two tight fixed rings 3, pin 4, connecting plate 5, it is characterized in that, described lever arm 1, positioning sleeve 2, tight fixed ring 3, pin 4, connecting plate 5 is rotary structure, described positioning sleeve 2 is upper and lower opening structure, internal thread is provided with in inner side, external screw thread is provided with outside described tight fixed ring 3, its screw thread and positioning sleeve 2 internal thread match, and have some slotted eyes, described connecting plate (5) is arranged in positioning sleeve (2), two tight fixed rings 3 are arranged in positioning sleeve 2 from upper and lower two ends respectively, described connecting plate 5 is fixed, described connecting plate 5 is provided with screwed hole, described pin 4 is provided with external screw thread, be fixed in the screwed hole of connecting plate 5 by threaded engagement, lever arm 1 is connected to outside positioning sleeve 2 for rotating whole spanner.
Preferably, with the external screw thread of the screw-internal thread fit with described positioning sleeve 2 on described connecting plate (5), be arranged in positioning sleeve 2 by threaded engagement.
Preferably, it is characterized in that, the screwed hole on described connecting plate (5) is two, and the center of circle of connecting plate described in is that axle becomes axial symmetry to arrange.
Preferably, the slotted eye described tight fixed ring 3 offered is along Axisymmetric.
Preferably, on described tight fixed ring 3, slotted eye is square hole groove
Preferably, on described tight fixed ring 3, slotted eye is circle hole groove.
Preferably, described lever arm 1 is two, is provided with external screw thread, has the internal thread hole that two symmetrical outside described positioning sleeve (2), and described lever arm 1 is linked at described positioning sleeve (2) two internal thread hole places outward by threaded engagement.
Beneficial effect of the present invention: this spanner easy making process, overcome conventional spanner in use easy to wear, wherein pin for suppressing metal is not replaceable, consumable accessory interchangeability is poor, when using simultaneously, in not rotatable location, tightening capstan nut outer ring, because rotation torque is large during assembling, easily cause spanner landing and cause the generation of casualty accident.This spanner, by combined integrated to lever arm 1, positioning sleeve 2, tight fixed ring 3, pin 4, connecting plate 5, can lead to as required and change connecting plate and pin, decrease production cost, playing a significant role for meeting multiple tightening capstan nut quick-detachment.

Wherein, 1-lever arm, 2-positioning sleeve, 3-tight fixed ring, 4-pin, 5-connecting plate, 6-capstan nut, 7-screw rod, 8-axle.
Detailed description of the invention
For better the present invention being described, illustrate below in conjunction with accompanying drawing.
Refer to Fig. 1 ~ Fig. 2, it is a kind of structural representation and the structural implementation of spanner of the present invention.
A kind of spanner, comprises lever arm 1, positioning sleeve 2, tight fixed ring 3, pin 4, connecting plate 5, it is characterized in that described lever arm 1, positioning sleeve 2, tight fixed ring 3, pin 4, connecting plate 5 are rotary structure.
Tight fixed ring 3, connecting plate 5, tight fixed ring 3 is loaded successively in described positioning sleeve 2.
Internal thread is provided with in described positioning sleeve 2.
Be provided with external screw thread outside described tight fixed ring 3, its screw thread and positioning sleeve 2 internal thread match.
Described tight fixed ring 3 has some slotted eyes.
Described tight fixed ring 3 offers slotted eye along Axisymmetric.
On described tight fixed ring 3, slotted eye is square hole groove or circle hole groove.
Described connecting plate 5 loads pin 4.
Described connecting plate 5 is provided with screwed hole.
The tight fixed ring 3 loaded in described positioning sleeve 2, connecting plate 5, tight fixed ring 3 are by screw threads for fastening.
Described pin 4 is provided with external screw thread.
Described positioning sleeve 2 is outer loads lever arm 1.
Described lever arm 1 is provided with external screw thread.
In present embodiment, spanner is through axle 8, the locating hole of positioning sleeve 2 with capstan nut 6 is coordinated, carry out coordinating with dowel hole in capstan nut 6 by pin 4 and locate, rotating lever arm 1, capstan nut 6 is screwed into or screw rod 7 of back-outing, the significant embodiment of the present invention is connecting plate 5 and pin 4 is the easy failed part of rapid wear, can change pin when in using, number of times is more, simultaneously in order to meet the capstan nut 6 of different size, connecting plate 5 can be customized as requested, tight fixed ring 3 and pin 4, decrease production cost, tool wrench safety employs customization tight fixed ring 3 use as locating ring, spanner in use landing is avoided to hurt sb.'s feelings.
This transmission shaft structure is simple, easy making process, overcome centering poor location that traditional structure brings and the shortcoming such as installation effectiveness is low, solve spanner in use easy to wear, pin for suppressing metal is not replaceable, consumable accessory interchangeability is poor, solves in tightening capstan nut outer ring revolution orientation problem simultaneously, avoids spanner landing and cause the generation of casualty accident.
