Description

Technical Field

[0001] This utility model relates to the field of drilling and tapping machine technology, specifically a positioning structure for drilling and tapping machines. Background Technology

[0002] A drilling and tapping machine is a metal cutting machine tool mainly used to machine internal threads, screws, or teeth into holes in parts. It comes in various types, including manual tapping machines, pneumatic tapping machines, electric tapping machines, in-mold tapping machines, and hydraulic tapping machines. Depending on the number of spindles, it can also be classified as single-axis tapping machines, two-axis tapping machines, four-axis tapping machines, six-axis tapping machines, and multi-axis tapping machines. To facilitate drilling into the workpiece, drilling and tapping machines are usually equipped with a positioning structure for fixing the workpiece in place.

[0003] A search revealed a positioning structure for a drilling and tapping machine, disclosed in patent application number CN202420067013.X. The structure includes a positioning base and a tapping machine body mounted on the positioning base. The positioning base is equipped with an elastic abutment and an adjustable positioning element that moves closer to or further away from the elastic abutment. A sleeve is mounted on the side of the elastic abutment away from the adjustable positioning element. A cavity is formed within the sleeve, and the end of the elastic abutment extends into the cavity. An opening communicating with the cavity is formed at the end of the sleeve away from the elastic abutment. An elastic scale element extends into the opening within the cavity, and an elastic bell element is mounted on the elastic scale element that abuts against the inner wall of the opening. This invention provides a positioning structure for a drilling and tapping machine, solving the problem of ineffectively measuring the magnitude of workpiece offset and providing early warning.

[0004] However, this patent has its shortcomings. The positioning plate used to clamp and position the workpiece on this drilling and tapping machine is a planar structure, so it can only be used for clamping and positioning planar workpieces such as plates, and cannot be used for positioning pipe workpieces, which makes the applicability of the equipment low. At the same time, since the fixed workpiece cannot move left and right within the positioning plate, when multiple holes need to be drilled in the lateral position of the workpiece, the operator can only remove the workpiece, readjust the position of the workpiece within the two positioning plates, and then clamp and position the workpiece again through the positioning plate before drilling can be performed. The operation steps in the drilling process are cumbersome and time-consuming, which can easily affect the drilling efficiency.

[0005] Therefore, we propose a positioning structure for drilling and tapping machines. Utility Model Content

A piston plate 18 is slidably connected in each air groove 17, and two uprights 20 are fixedly installed at the top of each piston plate 18. The tops of the multiple uprights 20 extend out of the fixed frame 2 and are respectively fixedly installed on the opposite side. On the corresponding pressure beam 4, the top of the fixed frame 2 and the bottom of the two pressure beams 4 are provided with arc grooves 19. The front and rear ends of the U-shaped frame 1 are provided with sliding grooves 5. The U-shaped frame 1 is provided with an installation groove 13 located on the right side of the two sliding grooves 5. The two sliding grooves 5 are rotatably connected with threaded rods 9. The right ends of the two threaded rods 9 extend into the installation groove 13 and are fixedly installed with gears 16. The two gears 16 are connected by meshing with a toothed belt 14. The front and rear ends of the movable seat 3 are fixedly installed with sliding blocks 10. The two sliding blocks 10 are respectively threaded onto the corresponding threaded rods 9.

[0018] A distance scale 12 is provided at the lower part of the slide groove 5 at the front end of the U-shaped frame 1. An arrow 11 is fixedly installed at the front end of one of the slide seats 10. The position of the arrow 11 on the distance scale 12 makes it easy to determine the distance the moving seat 3 moves to the left. An opening 6 is provided at the lower part of the distance scale 12 at the front end of the U-shaped frame 1. A pneumatic pump 7 is fixedly installed at the front end of the moving seat 3. The output end of the pneumatic pump 7 is connected to the inside of the T-slot 21. The pneumatic pump 7 can deliver compressed air into the T-slot 21 or extract compressed air. The top of the two output ends of the T-slot 21 is... The two air tanks 17 are connected to each other. This design is beneficial to the use of this equipment. A motor 15 is fixedly installed on the right side of the U-shaped frame 1. The output end of the motor 15 is fixedly installed on one of the gears 16. The motor 15 drives the gear 16 to rotate, which is beneficial to the use of this equipment. A PLC controller 8 is fixedly installed on the right side of the U-shaped frame 1 in front of the motor 15. The PLC controller 8 is used to control the operation of this equipment. The top of the fixed frame 2 is provided with a groove between the two pressure beams 4. The groove is provided to facilitate the tapping machine to drill holes in plates or pipes.

[0019] Working principle: The PLC controller 8 is electrically connected to the motor 15 and the pneumatic pump 7. During use, the U-shaped frame 1 is fixed to a suitable position on the tapping machine's positioning seat using multiple external bolts. The plate to be tapped is then placed at the bottom of the two pressure beams 4. The air extraction switch of the pneumatic pump 7 is turned on. The pneumatic pump 7 then extracts air from the T-slot 21 and the two air slots 17, causing the two piston plates 18 to drive multiple uprights 20 and the two pressure beams 4 to press down on the plate, thus clamping and fixing it. If tapping is required on pipes, the pipes are placed in the arc-shaped groove 19, and the same principle is used to clamp and fix them. Then, the tapping assembly on the tapping machine can be used to drill holes in the pipes or plates. When multiple holes need to be drilled, the switch of the motor 15 can be turned on after drilling. The motor 15 drives the gear 16 and the threaded rod 9 to rotate, causing the two slides 10 to move. 3. Slide to the left. Based on the position of the pointing arrow 11 on the distance scale 12, you can determine the distance the pipe or plate has shifted to the left. After adjusting to the appropriate position, you can drill again using the tapping assembly. When it is necessary to disassemble the drilled plate or pipe, turn on the air supply switch of the pneumatic pump 7, so that the two piston plates 18 drive the two pressure beams 4 to rise, thereby releasing the fixed limit on the plate or pipe. The circuit connection methods, mechanical structures, and connection relationships not mentioned in this manual are all conventional technical means in this field, so they will not be described in detail. The positioning structure of this drilling and tapping machine is easy to use. The above-mentioned components can simultaneously meet the clamping and positioning requirements of the pipe or plate, thereby further improving the applicability of this equipment. Moreover, the position of the plate or pipe at the bottom of the tapping assembly can be adjusted without disassembly, reducing the operation steps in the drilling process, thereby further improving the drilling efficiency.
