Description

Technical Field

[0001] The utility model relates to a rapid cutting device for an ultrasonic flaw detection guide sleeve, belonging to the technical field of ultrasonic flaw detection equipment. Background Art

[0002] Before the operation of the ultrasonic flaw detection equipment for silver bright materials, it is necessary to install a guide sleeve of corresponding specifications at the entrance of the flaw detection host according to different specifications. Since the guide sleeve is made of nylon, it will be severely worn during daily flaw detection operations. The worn guide sleeve will need to be used again according to its current specifications. For example, the guide sleeve with a 20mm aperture becomes an irregular inner diameter guide sleeve with an aperture of 20 to 22mm after wear. At this time, the flaw detection operator needs to perform secondary processing on the worn guide sleeve by manual grinding and cutting, so that the irregular inner diameter guide sleeve is processed into a guide sleeve with an inner diameter of 28, 29 or even 30mm. The size of the inner diameter after secondary processing depends on the processing level of the flaw detection operator. When the secondary processed guide sleeve is worn again, the flaw detection operator will process it again, and so on and so forth until the guide sleeve is worn to the maximum specification of the largest flaw detection bar.

[0003] Obviously, this method cannot reasonably and effectively utilize the guide sleeve. Not only is it easy to have the problem of uneven inner diameter, but the repeated utilization rate of the guide sleeve will also be greatly reduced. At the same time, the manual method will greatly increase the daily workload of the flaw detection personnel, thereby reducing the working efficiency of the flaw detection equipment.

DETAILED DESCRIPTION

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] like Figure 1As shown, an ultrasonic flaw detection guide sleeve quick cutting device in this embodiment includes a base 1, a guide sleeve base 14 is arranged in the center of the base 1, a material groove is opened in the center of the top of the guide sleeve base 14, the guide sleeve is arranged in the material groove, and a locking top block 13 is symmetrically arranged in the material groove. A vertically arranged locking screw is arranged on the top of the locking top block 13, and the locking screw passes through the top of the guide sleeve base 14. The locking screw and the guide sleeve base 14 are threadedly connected, and the bottom of the locking top block 13 is supported on the top of the guide sleeve. Tighten the locking screw so that the locking top block 13 presses against the guide sleeve, that is, the guide sleeve is fixed to the guide sleeve base 14; or loosen the locking screw so that the locking top block 13 is away from the guide sleeve, which is convenient for the guide sleeve to move out of the guide sleeve base 14. Two linear guide rails 2 arranged oppositely are arranged on both sides of the guide sleeve base 14, and the two linear guide rails 2 are vertically fixed on the base 1. Slide blocks are provided on the linear guide rail 2, and a horizontally arranged connecting plate 6 is provided between the two slide blocks. A horizontally arranged stepping gear coupling shaft 7 is passed through the connecting plate 6, and stepping gears 4 are provided at both ends of the stepping gear coupling shaft 7. Vertically arranged stepping racks 3 are provided on the sides of the linear guide rail 2, and the stepping gears 4 are meshed with the stepping racks 3 on the corresponding side. The stepping gear coupling shaft 7 is connected to the output shaft of the stepping motor 8. The stepping motor 8 drives the stepping gear coupling shaft 7 to rotate, and drives the two stepping gears 4 to rotate and move along the stepping rack 3, so that the connecting plate 6 and the slide block move up and down along the linear guide rail 2, and then approach or move away from the guide sleeve base 14. A vertically arranged DC brushless motor 9 is provided at the bottom of the connecting plate 6, and the linear brushless motor 9 corresponds to the guide sleeve base 14. The output shaft of the brushless DC motor 9 is fixedly connected to the adjustable cutter disc unit 11 through the tool chuck 10. Two oppositely arranged cutters 12 are provided at the bottom of the adjustable cutter disc unit 11. The adjustable cutter disc unit 11 drives the two cutters 12 to move closer to or farther from each other, adjusts the distance between the two cutters 12, and further adjusts the cutting range of the cutter. The brushless DC motor 9 drives the adjustable cutter disc unit 11 to rotate, drives the cutter 12 to rotate synchronously, and further cuts the guide sleeve.

[0018] like Figure 2As shown, the adjustable cutter disc unit 11 includes a cutter disc base 11.1, a screw end fixing block 11.3 is symmetrically arranged at the bottom of the cutter disc base 11.1, a screw middle fixing block 11.9 is arranged between the two screw end fixing blocks 11.3, a horizontally arranged screw 11.8 is passed through the screw end fixing block 11.3 and the screw middle fixing block 11.9, and the screw 11.8 has two sections of threads with opposite rotation directions: a first thread section and a second thread section, a first nut seat 11.4 is screwed on the first thread section, and a second nut seat 11.10 is screwed on the second thread section. A first linear guide rail 11.5 is arranged between a lead screw end fixing block and a lead screw middle fixing block, the first linear guide rail 11.5 is arranged above the first threaded section, a first linear slider 11.7 is arranged on the first linear guide rail 11.5, a first nut seat 11.4 is fixedly connected to the first linear slider 11.5, and a first tool base 11.6 is arranged on the first linear slider 11.5; a second linear guide rail 11.13 is arranged between another lead screw end fixing block and a lead screw middle fixing block, the second linear guide rail 11.13 is arranged above the second threaded section, a second linear slider 11.12 is arranged on the second linear guide rail 11.13, a second nut seat 11.10 is fixed to the second linear slider 11.12, and a second tool base 11.11 is arranged on the second linear slider 11.12. The bottoms of the first tool base 11.6 and the second tool base 11.11 are connected to the tool 12 respectively through tool screws. A crank 11.2 is sleeved on one end of the lead screw 12, so that the crank 11.2 can be quickly installed on the lead screw; turning the crank 11.2 drives the lead screw to rotate, so that the first nut seat and the second nut seat are moved closer to or farther away from each other, and then the first linear slide block and the second linear slide block are moved closer to or farther away from each other along the first linear slide rail, that is, the two tools are moved closer to or farther away from each other. After the cutting size is adjusted, the crank is disassembled to prevent the crank from flying out during the rotation of the cutter disc and causing a safety accident.

[0019] An electromagnetic brake pad 5 is arranged at the other end of the stepping gear coupling 7, which can brake the rotating stepping gear coupling and keep it stationary after power failure.

[0020] The corresponding cutting dimensions are engraved on the lead screw to facilitate adjustment to the required size.

[0021] Through two linear guides and a connecting plate, it is ensured that the two ends of the connecting plate are always at the same height when the stepper motor moves. A small brushless DC motor is installed at the bottom of the connecting plate, and the output shaft of the motor is connected to the adjustable cutter head unit through a tool chuck. A cutting tool is set on the adjustable cutter head unit, and the two are fixed by a tool screw, so that the tool is not easy to fall off when rotating. When the tool is worn, just remove the tool screw to replace the tool. The guide sleeve is placed on the guide sleeve base and fixed by a locking top block and a locking screw. Because the outer ring of the guide sleeve is the same size, it is only necessary to adjust the cutting range of the tool, and there is no need to design and make too much for the guide sleeve base.

[0022] The application has a simple structure and is easy to operate, improves the reuse rate of the guide sleeve of the ultrasonic flaw detection equipment, reduces the spare parts cost of the guide sleeve, reduces the workload of flaw detection personnel, and improves the flaw detection work efficiency.
