A special tool straightening mechanism for ultrasonic punching machine and implementation method thereof

Abstract

The invention relates to a tool straightening mechanism for an ultrasonic punching machine and a realization method thereof. The mechanism comprises an optical platform, a measuring component and an adjusting component. The measuring component and the adjusting component are respectively fixed in parallel on the optical platform. The micrometer of the measuring component is fixed on a precision linear module. The micrometer moves in three dimensions by moving a slide table so that the contact of the micrometer just contacts the surface of the tool. The tool is rotated 360 degrees, and the indication of the micrometer changes. The difference between the maximum and minimum indications is the radial runout value of this point. When the radial runout value is within 0.02-0.03 mm, it is normal. When the radial runout value is greater than 0.03 mm, the tool placed in the V-shaped groove of the magnetic table seat of the adjustment component is pressure-straightened by adjusting the linear motion of the screw rod and adjusting up and down. The entire tool straightening is completed by selecting three axial points. The effects are high adjustment accuracy, convenient operation, and improved straightening efficiency.

Description

Technical Field

[0001] The invention relates to an ultrasonic puncher, and in particular to a special tool straightening mechanism for an ultrasonic puncher and a realization method thereof. Background Art

[0002] Ultrasonic waves are sound waves with a frequency higher than 20,000 Hz, and are named because their lower frequency limit is greater than the upper limit of human hearing. They have good directionality, strong penetrating ability, and are easy to obtain concentrated sound energy. They can propagate over long distances in water and can be used for distance measurement, speed measurement, cleaning, welding, stone crushing, sterilization, and mechanical processing. The ultrasonic machining method is a method of vibrating a tool or workpiece by applying ultrasonic frequency vibration in a certain direction. Ultrasonic machining technology has developed rapidly in recent decades and has achieved significant results in hard material processing.

[0003] Ultrasonic drilling machine is an application of ultrasonic in mechanical processing and manufacturing. Ultrasonic drilling machine can drill holes on the surface of hard and brittle materials such as glass, engineering ceramics, quartz and marble. The optical fiber manufacturing industry needs to drill deep holes on optical fiber preform rods according to the process, and the hole depth reaches more than 300mm. This requires the tool to maintain a high straightness. Usually, the production steps of the drilling tool are: first cut the straight steel pipe to the length required by the tool; then straighten it once; after straightening, one end of the steel pipe is plated with diamond. However, since the straightness of the tool after straightening once does not meet the requirements of drilling, it cannot be used. At present, due to the lack of special tool straightening tools, the staff found that the tool was not straight when drilling. Experienced staff often use the method of bending the tool by hand to straighten it. This method is not only extensive and backward, but also time-consuming and affects work efficiency. When bending the tool, the radial clearance of the main shaft of the punching machine will also increase, affecting the punching accuracy of the punching machine. In order to solve the drawbacks of traditional ultrasonic punching machine straightening method, a special tool straightening mechanism for ultrasonic punching machine is proposed, which greatly improves the accuracy and efficiency of tool straightening of punching machine. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a tool straightening mechanism for an ultrasonic punching machine and an implementation method thereof. The specific technical scheme is a tool straightening mechanism for an ultrasonic punching machine, characterized in that it includes an optical platform, an adjustment component and a measuring component, characterized in that: the adjustment component includes: a base, a linear guide rail, a guide rail baffle, a bracket, an adjustment screw, a force rod, a pressure block, and a magnetic table seat. The base is a flat plate with a limited slot in the middle. The width of the limited slot is equal to the length of the bottom surface of the magnetic table seat. Two magnetic table seats are embedded in the limited slot.

[0005] The measuring component includes a connecting plate 1, a precision linear module, a servo motor, a connecting plate 2, a precision slide, a connecting plate 3, and a micrometer.

[0006] The pressing block is a hollow cylinder, with two clamping grooves and an inner boss on the inner surface, one end of the outer surface is a plane, and an arc-shaped groove is provided on the center line of the other end surface, and the diameter of the groove is the same as the outer diameter of the tool.

[0007] The V-shaped groove on the upper end surface of the magnetic table base has an opening width on the upper end surface of the V-shaped groove that is the same as the outer diameter of the tool.

[0008] The straightening steps are as follows: 1. Place the tool in the V-shaped groove on the upper end face of the magnetic base, rotate the knob on the magnetic base to make the magnetic base and the base absorb and fix, move the dial gauge head to any point near the axial center of the tool as the first measuring point, rotate the tool, and measure the radial runout value of the circular section at the first measuring point. When the radial runout value is within 0.02~0.03mm, it is normal. If the radial runout value is greater than 0.03mm, adjust this point; 2. Push the bracket to move along the linear guide rail to move the pressure block to the top of the first measuring point of the tool, rotate the force rod to rotate the adjusting screw, and the pressure block applies pressure downward.
