The positioning machine for steel wires of rims can clamp the rim, and simultaneously, stress of a steel wire of the rim can be automatically adjusted.

Description

Wheel rim steel wire localization machine

Technical field

The utility model relates to the equipment to the bicycle rim adjustment, the particularly a kind of wheel rim steel wire localization machine that can adjust steel wire stress to bicycle rim automatically.

Background technology

Bicycle need carry out the adjustment of steel wire stress to the wheel rim steel wire before dispatch from the factory, and will guarantee on the one hand can not have to be connected between wheel rim and the steel wire to become flexible, and also will check stress equilibrium between wheel rim and all steel wires; Otherwise after bicycle uses a period of time; The axle core center line that wheel rim can occur departs from the center line of wheel rim, influences safety by bike, for this reason need be when clamping wheel rim; To the axle core two ends of the wheel rim certain pressure of exerting pressure respectively, inspection discharges the stress after steel wire is locked with steel wire.

Summary of the invention

In order to remedy above deficiency, the utility model provides a kind of wheel rim steel wire localization machine, can when clamping wheel rim, adjust wheel rim steel wire stress automatically.

The technical scheme of the utility model is such realization: a kind of wheel rim steel wire localization machine; Comprise counterdie and the patrix that to place wheel rim and can drive first cylinder that this patrix is pressed to wheel rim on this counterdie; Also comprise core and can drive core this on and press to second cylinder of axle core on the wheel rim, also comprise down core and can drive this time core and press to the 3rd cylinder of a core under the wheel rim.

Further improvement as the utility model; This counterdie upwards forms the lower cavity die of being convenient to place wheel rim; This lower cavity die middle part has is convenient to the centre bore that the axle core stretches out under the wheel rim; This patrix forms the upper cavity die of being convenient to compress wheel rim ring limit downwards, and this upper cavity die middle part has is convenient to the centre bore that the axle core stretches out on the wheel rim.

As the further improvement of the utility model, also be connected in series a lower pressure sensor between this time core and the 3rd cylinder, also be connected in series a upward pressure sensor between core and this second cylinder on this.

As the further improvement of the utility model, this first cylinder and second cylinder are respectively a female cylinder and a sub-cylinder in the sub-mother-qi cylinder.

The useful technique effect of the utility model is: said counterdie, patrix and first cylinder are used for wheel rim is fixedly clamped; Said down core and the 3rd cylinder are used to aim at the axle core lower end of wheel rim and exert pressure; So that adjustment wheel rim below steel wire stress; Saidly go up the axle core upper end that core and second cylinder be used to aim at wheel rim and exert pressure, so that steel wire stress above the adjustment wheel rim is realized wheel rim steel wire stress is adjusted thus.

Also be connected in series a lower pressure sensor between said down core and said the 3rd cylinder; Said going up between core and said second cylinder also is connected in series a upward pressure sensor; Can apply different pressures to different wheel rims like this, satisfy different wheel rim steel wire stress adjustment requirements.

This first cylinder and second cylinder are respectively a female cylinder and a sub-cylinder in the sub-mother-qi cylinder, adopt a sub-mother-qi cylinder like this, add the 3rd cylinder and just reach the clamping wheel rim, and can adjust the requirement of wheel rim steel wire stress automatically.

The specific embodiment

A kind of wheel rim steel wire localization machine; Comprise counterdie 2 and the patrix 3 that to place wheel rim 10 and can drive first cylinder that this patrix 3 is pressed to wheel rim 10 on this counterdie 2; Also comprise core 7 and can drive core 7 this on and press to second cylinder of a core 101 on the wheel rim 10; Also comprise following core 6 and can drive the 3rd cylinder 4 that this time core 6 is pressed to axle core 102 under the wheel rim 10 that wherein: this first cylinder and second cylinder are respectively a female cylinder 11 and sub-cylinder 12 (representing like dotted line among Fig. 3) in the sub-mother-qi cylinder 1.

This counterdie 2 upwards forms the lower cavity die 21 (representing like dotted line among Fig. 2 and Fig. 3) of being convenient to place wheel rim 10; These lower cavity die 21 middle parts have is convenient to the centre bore that axle core 10 stretches out under the wheel rim 10; This patrix 3 forms the upper cavity die 31 (representing like dotted line among Fig. 2 and Fig. 3) of being convenient to compress wheel rim 10 ring limits downwards, and these upper cavity die 31 middle parts have is convenient to the centre bore that axle core 101 stretches out on the wheel rim 10.
