Background

After the alignment rod is arranged on the electric spindle of the traditional five-axis machine tool, the electric spindle can be manually and easily rotated to clamp and align the product reference hole under the condition of no cutting processing. The ultrasonic five-axis spindle cannot rotate under the condition that the electric spindle is not subjected to cutting machining due to the particularity of ultrasonic machining, so that the alignment of the product reference hole cannot be performed, and the alignment machining of the product cannot be performed according to the traditional method.

The spindle cannot rotate under the condition that the electric spindle does not cut, the alignment of the product reference hole cannot be carried out, and the product cannot be machined. An optical alignment instrument matched with a manufacturer must be purchased additionally, about one hundred thousand optical alignment instruments are used, and the optical alignment instrument is not only expensive but also poor in universality for products of different shapes. The other method is to use a probe which is distributed by a machine tool manufacturer, is only suitable for the alignment of small products, has the precision of about +/-0.15 mm and is unstable. For the condition that the precision requirement of the product is +/-0.015 mm, the common alignment rod can not meet the requirement.

SUMMERY OF THE UTILITY MODEL

Utility model purpose:

the utility model discloses a main aim at satisfies five axles of supersound because ultrasonic machining's particularity, five numerical control of supersound man-hour add man-hour, and the main shaft can't rotate under the condition that the electricity main shaft does not cut process, can't carry out the alignment in product benchmark hole, can't carry out the processing of product. The alignment problem of the product is solved.

The technical scheme is as follows: a rotary alignment rod for ultrasonic machining, clamping and aligning is composed of a cutter handle, a first extension rod, a taper bearing, a second extension rod and a dial indicator, wherein a clamping connector is arranged at the front end of the cutter handle and connected with an electric main shaft; the rear end of the knife handle is connected with the first extension bar, the first extension bar is connected with the second extension bar through a taper bearing, and the tail end of the second extension bar is provided with a dial indicator.

Preferably, the knife handle is connected with the first extension bar through a hydraulic mechanism, and the connection form is high in precision and convenient to detach.

Preferably, the tail end of the second extension rod is provided with a threaded hole, the dial indicator adopts a lever dial indicator, and a clamping rod of the dial indicator is fixed with the second extension rod through threaded fit.

Preferably, the taper bearing has higher precision, is convenient to mount, adjust and dismount, and can effectively ensure that the rotation precision of the second extension bar is within 0.01 mm; when the device is used, the second extension bar is manually rotated to drive the dial indicator to rotate, so that the detection before numerical control machining of the product reference hole and the establishment of a workpiece machining coordinate system are realized.

Preferably, first extension bar length is 5 times the length of second extension bar, more is favorable to guaranteeing the rotation accuracy of second extension bar for the axiality of second extension bar and lathe main shaft.

Preferably, the first extension bar and the second extension bar are both made of tungsten steel materials, and the tungsten steel materials are good in rigidity, high in stability and not prone to deformation.

Preferably, the bearing ratio of the electric main shaft of the ultrasonic machine tool to the taper bearing is combined, the diameter of the first extension bar is 2 times that of the second extension bar, and the service life and the precision stability of the electric main shaft of the ultrasonic machine tool and the taper bearing are protected.

Preferably, the upper end face of the taper bearing is provided with a load alarm, so that when the lever dial indicator and the reference hole are extruded and collided in the detection before numerical control machining of the product reference hole and the establishment process of the workpiece machining coordinate system, a warning sound is timely generated, and an operator is reminded to timely react.

The beneficial technical effects are as follows:

1) the structure is simple, and the conversion sleeve and the rod unit can be manufactured and assembled only by purchasing a precise taper hole bearing on the market.

2) The precision is high, and the alignment precision within +/-0.01 mm can be realized.

3) Good universality and convenient popularization.

4) The operation cost is greatly reduced.

Drawings

Figure 1 is a schematic view of a rotary alignment rod,

the device comprises a main shaft, a handle, a first extension bar, a second extension bar, a taper bearing, a first extension bar, a second extension bar and a dial indicator, wherein the main shaft is 1-an electric main shaft, the handle is 2-a handle, the first extension bar is 3-a 4-taper bearing, the second extension bar is 5-a dial indicator.

Detailed Description

Referring to the attached figure 1, the rotary alignment rod for ultrasonic machining, clamping and aligning comprises a cutter handle 2, a first extension bar 3, a taper bearing 4, a second extension bar 5 and a dial indicator 6, wherein a clamping joint is arranged at the front end of the cutter handle 2 and connected with an electric main shaft 1; the rear end of the knife handle 2 is connected with the first extension bar 3, the first extension bar 3 is connected with the second extension bar 5 through the taper bearing 4, and the tail end of the second extension bar 5 is provided with the dial indicator 6. Wherein, 3 length of first extension bar are 5 times of the length of second extension bar 5, and 3 diameters of first extension bar are 2 times of the 5 diameters of second extension bar, can guarantee the axiality of two extension bars limitedly, are convenient for adjust, and the 5 short thin designs of second extension bar can reduce the regulation error greatly.

As the five-axis numerical control machining of the product is basically realized by installing the lever dial indicator on the alignment rod and manually rotating the electric spindle to correct the reference hole on the product or the forming die. And the main shaft of the ultrasonic five-axis machine cannot rotate under the condition that the electric main shaft is not subjected to cutting machining due to the particularity of ultrasonic machining, so that the clamping and alignment of the product reference hole cannot be carried out, and the product cannot be machined. The utility model divides the traditional alignment rod into two parts, the middle part is provided with the conversion sleeve and the taper bearing, the part below the conversion sleeve can be the same as the traditional electric main shaft to realize the alignment of the product reference hole, the precision of the taper bearing is higher, the installation, the adjustment and the disassembly are convenient, and the rotation precision of the second extension rod can be effectively ensured within 0.01 mm; when the device is used, the second extension bar is manually rotated to drive the dial indicator to rotate, so that the detection before numerical control machining of the product reference hole and the establishment of a workpiece machining coordinate system are realized.

The utility model discloses the effectual five axles of supersound of having solved because main shaft can't rotate under the condition of the not cutting process of ultrasonic machining's specificity electricity main shaft, the cost has been practiced thrift greatly to the alignment demand of the current high accuracy product kind of specially adapted.
