Abstract
It the utility model is related to the accessory technical field of generating set, and in particular to a kind of round nut special assembling tool.Including assembly tool body, round nut, bent axle and torque spanner pipe coupling, the assembly tool body is formed by connecting by coaxial hollow big small cylinder integral type, the end bottom surface of wherein big cylinder is axially evenly distributed with the teeth one of four groups of protrusions, the tip inside face of big cylinder is radially even to be distributed with four groups of teeth two, the side of big cylinder is evenly equipped with some loss of weight through holes, wherein the side of small cylinder can be inserted in small cylinder just at least provided with through hole that is a pair of symmetrical and being connected, the torque spanner pipe coupling.Reduce the disassembly and assembly time of round nut using the round nut assembly tool, assembling effect stability is good, improves work efficiency, and reduce the labor intensity of worker, it is ensured that the assembling torque value of round nut and the locked position of crankshaft toothed wheel.
Description
Technical field
It the utility model is related to the accessory technical field of generating set, and in particular to a kind of special assembler of round nut
Tool.
Background technology
During the assembling work in generating set at present, for for fixed crankshaft gear, prevent crank teeth wheel shaft
To play round nut assembling work still by the way of manually impacting, tighten circular spiral shell by manually tapping iron staff
Mother, not only efficiency of assembling is low, and labor strength is big, and screw-down torque is unstable, sometimes tight slightly, sometimes partially loose, exists at the same time
Security risk, easily hurts operator.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of round nut special assembling tool.
Technical solutions of the utility model are as follows：
A kind of round nut special assembling tool, including assembly tool body, round nut, bent axle and torque spanner conversion
Connector, the assembly tool body is formed by connecting by coaxial hollow big small cylinder integral type, wherein the end of big cylinder
Bottom surface is axially evenly distributed with the teeth one of four groups of protrusions, and the tip inside face of big cylinder is radially even to be distributed with four groups of teeth
Tooth two, the side of big cylinder are evenly equipped with some loss of weight through holes, and wherein the side of small cylinder is at least provided with a pair of symmetrical and phase
The through hole of connection, the torque spanner pipe coupling can be inserted in small cylinder just, during operation, by the assembly tool sheet
Body is sheathed on bent axle, and it is uniformly distributed that the teeth one of its big cylinder ends can be inserted into the round nut periphery being connected on bent axle just
Four grooves in, and the end face of four groups of teeth two is just tangent with the lateral surface of bent axle at this time.
The beneficial effects of the utility model are：When reducing the dismounting of round nut using the round nut assembly tool
Between, assembling effect stability is good, improves work efficiency, and reduce the labor intensity of worker, it is ensured that the dress of round nut
Locked position with torque value and crankshaft toothed wheel.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Refering to Fig. 1 to Fig. 4, a kind of round nut special assembling tool, including assembly tool body 1, round nut 6, song
Axis 9 and torque spanner pipe coupling 8, the assembly tool body 1 are formed by connecting by coaxial hollow big small cylinder integral type,
The end bottom surface of wherein big cylinder is axially evenly distributed with the teeth 1 of four groups of protrusions, the tip inside face edge of big cylinder
Radially uniform that four groups of teeth 22 are distributed with, the side of big cylinder is evenly equipped with some loss of weight through holes 4, the wherein side of small cylinder
Face can be inserted in small cylinder just at least provided with through hole 4 that is a pair of symmetrical and being connected, the torque spanner pipe coupling 8
It is interior, during operation, the assembly tool body 1 is sheathed on bent axle 9, the teeth 1 of its big cylinder ends can be inserted into just
In four uniformly distributed grooves 7 of the periphery of round nut 6 that is connected on bent axle 9, and at this time the end face of four groups of teeth 22 just with song
The lateral surface of axis 9 is tangent.
During operation, round nut will be pressed on this round nut assembly tool set to bent axle 9 and by the teeth 1 of its end
In 6 four grooves 7, torque spanner pipe coupling 8 is then loaded to the other end of round nut assembly tool, passes through a root long
Iron staff make both to be connected to together through the through hole 5 on the through hole and torque spanner pipe coupling 8 on small cylinder, then will turn round
Torque wrench head square knuckle is filled in the pit on 8 head of torque spanner pipe coupling, can be wrenched by rotary torsion spanner
Round nut is to specific torsion.
Above-mentioned accompanying drawings and embodiments are merely to illustrate the utility model, and any technical field those of ordinary skill is to it
The appropriate change or modification done, or use other flower pattern instead and make this technical change, it all should be regarded as not departing from this practicality newly
Type patent category.
