Description

It is a kind of to pull rifle component automatically

Technical field

The utility model relates to automobile assembling tools, and in particular to a kind of to pull rifle rifle component automatically.

Background technique

In order to meet the required precision of fender assembly, and the reasonable Ergonomics design of realization, in the dress of fender With in the process generally using fixture to the high fine positioning of fender progress.And in order to the assembly in fender overcome the limitation in space with And guarantee efficient requirement, the urgent positioning bolt of rifle or location nut need to be pulled using automatic wind.Automatic wind in the prior art It pulls and sleeve is installed on the output shaft of rifle, the end of sleeve is equipped with the inner hole for matching with positioning bolt or location nut, The section of the inner hole is in non-circular；The root of sleeve is pulled with automatic wind to be connected by way of clamping between the output shaft of rifle, and Sleeve and automatic wind, which are pulled, can transmit torque between the output shaft of rifle.In use, under the action of the gravity of sleeve, set The output shaft that cylinder pulls rifle relative to automatic wind is always at tenesmus state, leads to the position deviation of sleeve appearance radially, therefore The positioning bolt or location nut that fender is easy to appear in assembling process assemble not in place or even are unable to complete showing for assembly As being reprocessed and being carried out appearance debugging, increase cost and be unfavorable for the promotion of production efficiency.

Summary of the invention

The purpose of this utility model is to propose that one kind pulls rifle component automatically, above-mentioned technical problem is mitigated or eliminated.

One kind described in the utility model pulls rifle component automatically, including pulls rifle and sleeve automatically, described to pull the defeated of rifle automatically The output end of shaft is equipped with connection-peg, and the right part of the sleeve is sleeved on the connection-peg, the sleeve and the connection-peg It is circumferentially fixed, detachable axial locking structure is equipped between the sleeve and the connection-peg, the left part of the sleeve, which is equipped with, to be used In the inner hole matched with bolt head or nut, the central axis of the inner hole is conllinear with the central axis of the output shaft, institute The root for stating connection-peg is equipped with the step surface extended radially outward, is set with elastic ring, the elastic ring on the connection-peg Between the step surface and the right side of the sleeve, the elastic ring and the step surface Elastic Contact and the elasticity The right side Elastic Contact of circle and the sleeve.

Further, the connection-peg is in prism shape.

Further, the detachable axial locking structure includes the steel ball being embedded on the connection-peg and is arranged in institute The card hole stated on the inner wall of sleeve and engaged with the steel ball.

Further, the elastic ring is made of rubber.

The utility model has the advantage of the elastic rings that setting structure is simple and is easy to buy to solve technical problem, utilize The bounce of elastic ring reduces influence of the gravity of sleeve to sleeve radial position, reduce the gravity of sleeve to sleeve with from The influence of the concentricity of the dynamic output shaft for pulling rifle, to ensure the accuracy and stability of sleeve portion, and then improves spiral shell The one-time success rate of bolt or nut automatic assembling effectively reduces and reprocesses cost and appearance debugging cost under line.

Fig. 2 is the explosive view of Fig. 1.

In figure: 1-pulls rifle automatically；2-output shafts；3-sleeves；4-elastic rings；5-connection-pegs；6-step surfaces；7— Right side.

Specific embodiment

One kind as depicted in figs. 1 and 2 pulls 1 component of rifle automatically, including pulls rifle 1 and sleeve 3 automatically, pulls the defeated of rifle 1 automatically The output end of shaft 2 is equipped with connection-peg 5, and the right part of sleeve 3 is sleeved on connection-peg 5, and sleeve 3 and connection-peg 5 are circumferentially fixed, set Detachable axial locking structure is equipped between cylinder 3 and connection-peg 5, the left part of sleeve 3 is equipped with for matching with bolt head or nut The inner hole of conjunction, bore openings are towards a left side, and the central axis of inner hole is conllinear with the central axis of output shaft 2, and the root of connection-peg 5 is equipped with The step surface 6 extended radially outward, step surface 6 can be formed in the left end of the axle body of output shaft 2 and the right end of connection-peg 5 Between transition face, be set with elastic ring 4 on connection-peg 5, elastic ring 4 is located between step surface 6 and the right side 7 of sleeve 3, bullet Property circle 4 and 6 Elastic Contact of step surface and elastic ring 4 and sleeve 37 Elastic Contact of right side, elastic ring 4 holds out against sleeve 3 to the left.

In the specific implementation, connection-peg 5 is in prism shape, and connection-peg 5 generally uses section for the four prisms cylinder of rectangle, is covered Sleeve 3 can be realized equipped with the prism-shaped hole matched with connection-peg 5 for the right part of cylinder 3 and connection-peg 5 is circumferentially fixed, prism-shaped hole Opening towards the right side.

In the specific implementation, detachable axial locking structure includes that the steel ball being embedded on connection-peg 5 and setting are covering The card hole engaged on the inner wall of cylinder 3 and with steel ball.Sleeve 3 can be installed or removed by applying enough axial forces to sleeve 3, be utilized The axial locking of sleeve 3 and connection-peg 5 may be implemented in steel ball and card hole cooperation.

In the specific implementation, elastic ring 4 is made of rubber, and elastic ring 4 made of rubber is to be easy to buy, at low cost.

In the specific implementation, rifle can be pulled or pneumatically pull rifle to be electronic by pulling rifle 1 automatically, it is electronic pull rifle can also be called it is electronic Spanner or Electric trigger, it is electronic to pull rifle or pneumatically pull the auxiliary tool that rifle is extensive utilization in the prior art.

By adopting the above technical scheme, sleeve 3 is held out against to the left using the bounce of elastic ring 4, so that card hole holds out against steel to the left Pearl can reduce influence of the gravity of sleeve 3 to 3 radial position of sleeve, reduce the gravity of sleeve 3 to sleeve 3 with pull automatically The influence of the concentricity of the output shaft 2 of rifle 1 to ensure the accuracy and stability of 3 position of sleeve, and then improves bolt Or the one-time success rate of nut automatic assembling, be able to ascend fender positioning bolt or location nut automatic assembling it is primary at Power effectively reduces and reprocesses cost and appearance debugging cost under line.
