Abstract
The invention relates to a retightening tool special for a narrow space, comprising a connecting rod, wherein one end of the connecting rod is coaxially provided with an open-end spanner head, and the other end of the connecting rod is provided with a box spanner head in a welding way. The box spanner head is provided with a through hole, and the axis of the through hole of the box spanner head is orthogonal to the axis of the connecting rod. Because a common open-end spanner and a manual box spanner are arranged on two ends of the connecting rod and are welded into a whole, the purpose of carrying out assembly in a narrow space (such as a vehicle transmission shaft and a rear-axle connecting flange face), which can not be completed with common sleeves, is achieved, therefore, six faces of a bolt (nut) are stressed uniformly with reliable retightening torque and convenience in operation, and reworking and awkward situations cannot be resulted in. The tool is simple to manufacture, low is cost and free from maintenance.
Description
Technical field
The present invention relates to a kind of hand assembled instrument, especially relating to a kind of screw thread pair securing member special use instrument of tightening up that is used for small space is spanner.
Background technology
At present, in mechanical industry main engine plants,, in the time of can't assembling with common sleeve, must assemble with open-end wrench when relating to the narrow and small place of assembly space screw thread pair securing member.Open-end wrench is that two faces are stressed, in case moment surpasses 50Nm, driving end begins distortion, causes slipping out from being assembled bolt head, can't dismantle and assemble, and allows very headache and can't guarantee to assemble moment of people.Owing to lack the reliability of assembling; Therefore have to lose time and assemble again or reprocess.The problem of bringing like this is a series of problems such as consuming time long, rework cost height.
Chinese patent application 200510030801.3 discloses a kind of open mouth type double offset ring spanner, comprise movable semi-ring, stationary half, the front and back connecting plate, tommy bar, at least one end of tommy bar is provided with movable semi-ring and stationary half, it is characterized in that stationary half is fixedly connected between the connecting plate of front and back, the activity semi-ring is connected on the stationary half, movable semi-ring employing activity semi-ring pin is fixedly connected between the connecting plate of front and back, movable semi-ring left end is provided with a projection contact, tommy bar one end adopts the tommy bar shop bolt to be fixed between the connecting plate of front and back, the tommy bar right-hand member is provided with the projection contact, the projection contact is between projection contact and projection contact, and the left side, projection contact is provided with a safety plug.Its weak point is that complex structure is not suitable for the bolt (nut) of tightening big moment in the small spaces such as truck drive shaft and back axle adpting flange face yet.
Summary of the invention
The purpose of this invention is to provide a kind of special use that is used for small space and tighten up instrument, solve small space the screw thread pair securing member fast, decide the moment assembly problem.
The technical solution adopted for the present invention to solve the technical problems is: a kind of special use that is used for small space tightens up instrument, comprises connecting rod, and the coaxial opening head driving end that is provided with of connecting rod one end is characterized in that: in the welding of the connecting rod other end double offset ring spanner head is set.
Further, the described double offset ring spanner head double offset ring spanner head that is through hole.
Further, the through-bore axis of described double offset ring spanner head and connecting rod axis quadrature.
The sleeve height of described double offset ring spanner head is identical with connecting rod thickness.
Beneficial effect of the present invention: because employing is provided with common opening head spanner at the two ends of connecting rod, add manual double offset ring spanner, both are welded into one, reach at small space (as at truck drive shaft and back axle adpting flange face) screw thread pair securing member and can't assemble with ordinary cartridge, thereby realized that six on bolt (nut) is stressed even, it is reliable to tighten up moment, easy to operate, can not cause and do over again and some how-do-you-dos.
This tool making is simple, and is cheap, avoids safeguarding.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is that the special use that is used for small space tightens up the tool configuration schematic perspective view.
Among the figure: 1. connecting rod, 2. opening head driving end, 3. double offset ring spanner head.
The specific embodiment
Further, the described double offset ring spanner head double offset ring spanner head that is through hole.
Further, the through-bore axis of described double offset ring spanner head and connecting rod axis quadrature.
The sleeve height of described double offset ring spanner head is identical with connecting rod thickness.
Described connecting rod radial width value 13mm, double offset ring spanner headgear tube internal diameter value 15mm.
Described connecting rod, opening head driving end and double offset ring spanner head all adopt tool steel to make.
The dimensions that the double offset ring spanner head is assembled in the special use that is used for the screw thread pair securing member of small space of the present invention can be made into the size that other is fit to according to the situation of assembly space or securing member.
Above-described embodiment is a kind of of the more preferably concrete embodiment of the present invention, and common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacement all should be included in protection scope of the present invention.
Claims (6)
1. a special use that is used for small space tightens up instrument, comprises connecting rod, and the coaxial opening head driving end that is provided with of connecting rod one end is characterized in that: in the welding of the connecting rod other end double offset ring spanner head is set.
2. the special use that is used for small space as claimed in claim 1 tightens up instrument, it is characterized in that: the double offset ring spanner head that described double offset ring spanner head is a through hole.
3. the special use that is used for small space as claimed in claim 1 or 2 tightens up instrument, it is characterized in that: the through-bore axis of described double offset ring spanner head and connecting rod axis quadrature.
