Description

Technical Field

[0001] This utility model relates to the field of non-magnetic steel insert production and processing technology, specifically a precision anti-offset wire cutting device for non-magnetic steel inserts. Background Technology

[0002] Non-magnetic steel inserts are widely used in maglev trains, electronic equipment, and precision instruments due to their low magnetism, corrosion resistance, and high strength and toughness. The production and processing of non-magnetic steel inserts generally requires the use of wire cutting equipment. Wire cutting equipment is a device that uses the principle of electric spark discharge to cut and shape metals and non-metals. It uses a thin metal wire, i.e., an electrode wire, as an electrode to perform pulsed spark discharge on the workpiece to remove the metal. However, there are still some drawbacks in the actual use of wire cutting equipment for non-magnetic steel inserts.

[0003] The wire cutting head electrode of the wire EDM equipment for non-magnetic steel inserts is prone to displacement due to its relatively slender appearance, and it is also difficult to intelligently monitor the horizontal and vertical cutting positions, which greatly affects the precision of the cutting process and its practicality. Based on this, we propose a new type of precision anti-displacement wire EDM equipment for non-magnetic steel inserts. Utility Model Content

[0004] The purpose of this invention is to provide a precision anti-offset wire cutting device for non-magnetic steel inserts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision anti-offset wire cutting device for non-magnetic steel inserts, comprising an upper base, a lower worktable welded to the bottom of the upper base, a fixing seat for non-magnetic steel inserts mounted on the top of the lower worktable by screws, telescopic cylinders fixed on both sides of the fixing seat for non-magnetic steel inserts, a clamping member connected to the output end of the telescopic cylinder, and a pressure sensor mounted on the clamping member, a controller mounted on the outer wall of the upper base, and horizontal and vertical adjustment housings evenly fixed at the top of the interior of the upper base, with adjacent horizontal and vertical adjustment housings... A horizontally adjustable housing is slidably connected. A motor is fixed to one side of the horizontally adjustable housing and one end of the horizontally adjustable housing. A worm, a worm wheel, a lead screw, and a nut seat are sequentially installed inside the horizontally adjustable housing and the horizontally adjustable housing. A pulse generator is welded onto the nut seat. A wire-cutting electrode is provided at the output end of the pulse generator. A positioning tube and a limiting cylinder matching the wire-cutting electrode are sequentially installed at the bottom of the pulse generator. A horizontally adjustable laser rangefinder sensor for longitudinal and horizontal directions matching the upper top seat are sequentially installed on the outer wall of the positioning tube.

[0006] Preferably, the four corners of the bottom of the lower workbench are fitted with anti-slip rubber feet.

[0007] Preferably, there are two horizontal and vertical adjustment housings, and the top of the horizontal and vertical adjustment housings and the upper top seat are welded together.

[0008] Preferably, the worm gear is connected to the output end of the motor, and the lead screw and worm wheel are welded together.

[0009] Preferably, the nut seat is threaded onto the lead screw.

[0010] Preferably, both the positioning tube and the limiting cylinder are hollow structures, and the positioning tube and the pulse generator, as well as the limiting cylinder and the positioning tube, are connected by screws to form a disassembly and installation structure.

[0011] Preferably, a guide slide rod is welded to one end of the horizontal adjustment housing, and a guide groove is provided on the upper top seat that is slidably connected to the guide slide rod, thereby improving the stability of the horizontal adjustment housing during movement.

[0012] Preferably, both the horizontal adjustment housing and the horizontal longitudinal adjustment housing are provided with slide rails that match the nut seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The precision anti-offset wire cutting equipment with non-magnetic steel inserts is equipped with a pulse generator, etc., so that when the device is in operation, on the one hand, the horizontal longitudinal laser range sensor and the horizontal transverse laser range sensor that match the upper top seat are installed in sequence on the outer wall of the positioning tube, so that when the drive mechanism inside the horizontal longitudinal adjustment housing and the horizontal transverse adjustment housing controls the movement of the wire cutting electrode, the horizontal longitudinal laser range sensor and the horizontal transverse laser range sensor can respectively intelligently monitor the horizontal longitudinal distance between the positioning tube and the upper top seat and the horizontal transverse distance between the positioning tube and the upper top seat in real time, and then send the monitored data to the controller. This facilitates the intelligent calculation and monitoring of the horizontal longitudinal and horizontal transverse cutting positions of the wire cutting electrode, realizing intelligent and high-precision cutting processing. On the other hand, the positioning tube and the limiting cylinder that match the wire cutting electrode are installed in sequence at the bottom of the pulse generator. The tail of the wire cutting electrode will pass through the limiting cavity inside the positioning tube and the limiting cylinder to perform the cutting operation. This can perform anti-offset limiting treatment on the wire cutting electrode and avoid the problem of the slender wire cutting electrode being deflected by the wind and other factors.

[0015] (2) The precision anti-offset wire cutting equipment for non-magnetic steel inserts optimizes its performance by installing a horizontal and vertical adjustment housing. On one hand, the user can place the non-magnetic steel insert product to be cut on the non-magnetic steel insert fixing seat, then activate two symmetrically distributed telescopic cylinders to change the distance between the two clamping parts, thus clamping and fixing the non-magnetic steel insert product. Furthermore, by installing pressure sensors on the clamping parts, the clamping pressure can be monitored, and the monitored data can be sent to the controller. This facilitates intelligent control of the tightness of the clamping and fixing of the non-magnetic steel insert product, improving both production efficiency and efficiency. This ensures stability during product cutting and avoids damage to the product due to excessive clamping force. On the other hand, after the corresponding motors on the horizontal longitudinal and horizontal transverse adjustment housings are started, they will first drive the worm gear connected to them to move, and then drive the worm wheel that matches the worm gear to move. Only then can the lead screw be driven to rotate and the nut seat on the lead screw to slide. In addition, by adding a transmission mechanism consisting of a worm gear and a worm wheel, based on the self-locking effect of the worm wheel driving the worm gear to move in the opposite direction, it can be ensured that the lead screw can be locked immediately after the motor stops. This helps to avoid the problem of the wire cutting head electrode cutting position shifting due to the lead screw loosening and moving, and improves the processing accuracy.

[0016] (3) The precision anti-offset wire cutting equipment for the non-magnetic steel insert has optimized its structure by setting guide grooves, etc. On the one hand, the sliding guide effect formed by the guide rod and the guide groove improves the smoothness of the horizontal longitudinal adjustment housing when the internal drive mechanism drives the horizontal transverse adjustment housing to move automatically along the horizontal longitudinal direction. On the other hand, by setting the positioning tube and pulse generator and the limit cylinder and positioning tube are all connected by screws to form a disassembly and installation structure, it is easy to realize the independent disassembly and maintenance of the limit cylinder and positioning tube.

[0024] Please see Figure 1-5 The present invention provides an embodiment of a precision anti-offset wire cutting device for non-magnetic steel inserts, comprising an upper top seat 1, a lower worktable 2 welded to the bottom of the upper top seat 1, and a non-magnetic steel insert fixing seat 5 installed on the top of the lower worktable 2 by screws.

[0025] Telescopic cylinders 21 are fixed on both sides of the non-magnetic steel insert fixing base 5. The output end of the telescopic cylinder 21 is connected to a clamping member 22, and a pressure sensor 23 is installed on the clamping member 22. A controller 14 is installed on the outer side wall of the upper top base 1.

[0026] In use, the user can place the non-magnetic steel insert product to be cut on the non-magnetic steel insert fixing base 5, and then activate the two symmetrically distributed telescopic cylinders 21 to change the distance between the two clamping parts 22 to clamp and fix the non-magnetic steel insert product to be cut. Furthermore, by installing pressure sensors 23 on the clamping parts 22, the clamping pressure can be monitored, and the monitored data can be sent to the controller 14.

A pulse generator 11 is welded on the nut seat 17.

[0028] In use, after the corresponding motors 9 on the horizontal longitudinal adjustment housing 10 and the horizontal transverse adjustment housing 12 are started, they will first drive the worm 19 connected to it to move, and then drive the worm wheel 20 that matches the worm 19 to move. Only then can the lead screw 16 be driven to rotate and the nut seat 17 threaded on the lead screw 16 to slide. In addition, by adding the transmission mechanism composed of the worm 19 and the worm wheel 20, based on the self-locking effect of the worm wheel 20 driving the worm 19 to move in the opposite direction, it can be ensured that the lead screw 16 can be locked after the motor 9 stops. This helps to prevent the lead screw 16 from loosening and moving and improves the machining accuracy.

[0029] The output end of the pulse generator 11 is provided with a wire cutting electrode 13. The bottom of the pulse generator 11 is sequentially equipped with a positioning tube 24 and a limiting cylinder 6 that match the wire cutting electrode 13.

[0030] Two horizontal and vertical adjustment housings 10 are provided, and the top of the horizontal and vertical adjustment housing 10 and the upper top seat 1 are welded together.

[0031] The worm gear 19 is connected to the output end of the motor 9, and the lead screw 16 and the worm wheel 20 are welded together.

[0032] Nut seat 17 is threaded onto lead screw 16;

[0033] In use, by sequentially installing a horizontal longitudinal laser rangefinder 4 and a horizontal transverse laser rangefinder 7, which are matched with the upper top seat 1, on the outer wall of the positioning tube 24, when the drive mechanism inside the horizontal longitudinal adjustment housing 10 and the horizontal transverse adjustment housing 12 controls the movement of the wire cutting electrode 13, the horizontal longitudinal laser rangefinder 4 and the horizontal transverse laser rangefinder 7 can intelligently monitor the horizontal longitudinal distance between the positioning tube 24 and the upper top seat 1 and the horizontal transverse distance between the positioning tube 24 and the upper top seat 1, respectively, and then send the monitored data to the controller 14. This facilitates the intelligent calculation of the horizontal longitudinal and horizontal transverse cutting positions of the monitoring wire cutting electrode 13, realizing intelligent and high-precision cutting processing.

[0034] The four corners at the bottom of the lower workbench 2 are all fitted with anti-slip rubber feet 3;

[0035] Both the positioning tube 24 and the limiting cylinder 6 are hollow structures. The positioning tube 24 and the pulse generator 11, as well as the limiting cylinder 6 and the positioning tube 24, are connected by screws to form a disassembly and installation structure.

[0036] A guide slide rod 8 is welded to one end of the horizontal adjustment housing 12, and a guide slide groove 15 that is slidably connected to the guide slide rod 8 is provided on the upper top seat 1, which improves the stability of the horizontal adjustment housing 12 when it moves.

[0037] Both the horizontal adjustment housing 12 and the horizontal longitudinal adjustment housing 10 are equipped with slide rails 18 that match the nut seat 17.

[0038] In use, according to this embodiment: First, an external power supply is connected. The user can place the non-magnetic steel insert product to be cut on the non-magnetic steel insert fixing base 5. Then, the two symmetrically distributed telescopic cylinders 21 are activated to change the distance between the two clamping members 22, thereby clamping and fixing the non-magnetic steel insert product to be cut. Furthermore, by installing pressure sensors 23 on the clamping members 22, the clamping pressure can be monitored, and the monitored data is sent to the controller 14. This facilitates intelligent control of the tightness of the clamping and fixing of the non-magnetic steel insert product, which not only improves the stability of the product cutting process but also avoids damage to the product due to excessive clamping force. On the other hand, the horizontal longitudinal adjustment housing 10 and the horizontal transverse adjustment housing 1... After the motor 9 on the 2nd plate starts, it will first drive the worm 19 connected to it to move, and then drive the worm wheel 20 that matches the worm 19 to move. Only then can it drive the lead screw 16 to rotate and the nut seat 17 threaded on the lead screw 16 to slide. In addition, by adding a transmission mechanism consisting of worm 19 and worm wheel 20, based on the self-locking effect of the worm wheel 20 driving the worm 19 to move in the opposite direction, it can be ensured that the lead screw 16 can be locked after the motor 9 stops. This helps to avoid the problem of the wire cutting head electrode 13 shifting due to the loosening and movement of the lead screw 16, and improves the processing accuracy. At the same time, by installing horizontal and longitudinal laser range sensors that match the upper top seat 1 on the outer wall of the positioning tube 24, the overall process is completed. The laser rangefinder 4 and the horizontal-lateral laser rangefinder 7 enable the drive mechanism inside the horizontal-vertical adjustment housing 10 and the horizontal-lateral adjustment housing 12 to control the movement of the wire cutting electrode 13.

The monitored data is then sent to the controller 14, facilitating its intelligent calculation of the horizontal-vertical and horizontal-lateral cutting positions of the wire cutting electrode 13, thus achieving intelligent and high-precision cutting processing. Furthermore, by sequentially installing a positioning device matching the wire cutting electrode 13 at the bottom of the pulse generator 11... The tail of the wire cutting electrode 13 passes through the positioning tube 24 and the limiting cylinder 6 to perform the cutting operation. This can prevent the wire cutting electrode 13 from deviating and avoid the problem of the slender wire cutting electrode 13 deviating to the side under the influence of wind. In addition, the sliding guide formed by the guide slide rod 8 and the guide slide groove 15 improves the smoothness of the horizontal longitudinal adjustment housing 10 when the internal drive mechanism drives the horizontal transverse adjustment housing 12 to move automatically along the horizontal longitudinal direction. Furthermore, by setting the positioning tube 24 and the pulse generator 11 and the limiting cylinder 6 and the positioning tube 24 to be connected by screws to form a disassembly and installation structure, it is easy to independently disassemble and maintain the limiting cylinder 6 and the positioning tube 24.
