Description

Technical Field

[0001] The invention relates to the technical field of permanent magnet motors, in particular to a permanent magnet motor for a numerical control machine tool which is easy to disassemble. Background Art

[0002] A permanent magnet motor is an electric motor whose core feature is the use of permanent magnets to generate a magnetic field, thereby simplifying the motor design and improving efficiency. The main components of a permanent magnet motor include permanent magnets as part of the rotor or stator, and three-phase windings as another part of the motor. This type of motor does not require an external power supply or brushes to generate torque because the permanent magnets on the rotor directly generate the magnetic field. The advantages of permanent magnet motors include high power density, high control accuracy, low noise, high efficiency, and simple structure, which make permanent magnet motors very popular in applications that require precise control of speed and torque, such as CNC machine tools, precision instruments, etc.

[0003] However, during the use of permanent magnet motors in CNC machine tools, when operators inspect and repair the connecting wires or terminals in the junction box, they need to use tools to remove the bolts that fix the box cover from the junction box first. There are many bolts, and disassembly and assembly are cumbersome; and the box cover is placed aside, and the staff may accidentally touch the box cover when operating with a large amplitude, and then the fixing bolts may be lost when it falls over, affecting the operator's re-fixing of the box cover; the motor is prone to vibrate during use, and after long-term use, the motor fixing components may loosen, which may cause its position to shift, resulting in reduced work efficiency. Summary of the invention

[0006] Specifically, the limiting mechanism includes a resist block and a pull ring, the mounting block is resisted by a resist block, the pull ring and the sliding rod are fixed on the resist block, the sliding rod is resisted by a resist plate, the end of the resist plate close to the resist plate is fixedly installed with a telescopic spring, the telescopic spring is fixedly connected to the mounting block, the resist plate is slidably connected to the rotating block, the mounting block is rotatably connected with a roller, a through groove is provided in the mounting block, the height of the resist block is greater than the distance between the two sliding rods, the sliding rod is slidably connected to the mounting block, the two groups of rollers are symmetrically arranged, and the rollers are rollingly connected to the resist plate, the width of the through groove is greater than the width of the rotating block, and the rotating block is rotatably connected to the through groove.

[0007] Specifically, the connecting mechanism includes a rotating plate and a connecting rod. A rotating plate is fixedly installed on the end of the box cover facing away from the rotating block. The rotating plate is fixedly connected to the connecting rod. A supporting block is fixedly connected to the junction box. The connecting rod and the supporting block are rotatably connected. A frame is snap-fitted and installed on the bottom end of the junction box. Terminals are fixed on the frame. The two support blocks are symmetrically arranged, and the junction box is in conflict with the box cover.

[0008] Specifically, the supporting mechanism includes a fixed base and a card block. The bottom end of the motor body is installed with a fixed base, and a card block and a supporting frame are fixedly installed on the fixed base. Two groups of card plates are fixedly connected to the supporting frame, and a card slot is provided on the card plate. A fixed block is fixedly connected to the motor body, and a card block is engaged with the card slot.

[0009] Specifically, the fixing mechanism includes a bed body and a limit block, the top end of the motor body is fixedly connected to the limit block, the limit block is snap-connected with the bed body, the bed body is provided with a limit groove and a through hole, the limit groove is snap-fitted with the limit block, and the through hole is snap-fitted with the motor body.

[0010] The beneficial effects of the present invention are:

[0011] (1) The present invention discloses a permanent magnet motor for a CNC machine tool that is easy to disassemble. The motor body is fixed on a supporting mechanism, and the supporting mechanism is then snapped into the interior of the fixing mechanism, so that the motor body can be quickly installed on the machine tool, thereby facilitating the motor body to be prevented from being displaced during the disassembly and assembly process. That is, when the operator installs the fixed base provided at the bottom end of the motor body on the supporting frame, the operator can first snap the fixed block on the fixed base into the slot provided between the two clamping plates. Since the slot and the block have the same shape, when the fixed base slides on the top of the supporting frame, the block can slide in the slot with the fixed base. The setting of the slot can prevent the motor body from being displaced. After long-term use, the position of the fixed base is displaced; use tools to install bolts on the fixed base and the support frame, so as to facilitate the limiting of the fixed base; when fixing the support frame on the bed, the limit block fixed on the top of the motor body can be first engaged with the limit groove provided on the bed. When the limit block conflicts with the inner wall of the bed, the limit block can be limited. At this time, the output shaft of the motor body passes through the bed through the through hole provided on the bed, and then the support frame can be firmly installed on the side wall of the bed through the fixing bolts, thereby facilitating the operator to quickly fix the motor body while preventing the motor body from having errors in position after disassembly and assembly.

[0012] (2) The present invention discloses a permanent magnet motor for a CNC machine tool that is easy to disassemble. The box cover is rotated to drive the connecting mechanism to rotate, thereby putting the junction box in an open state, which makes it easy for the operator to install and fix the connecting wires of the motor body. That is, after fixing the motor body, the operator can place the junction box on the top of the motor body, and then rotate the box cover to make the box cover drive the rotating plate to rotate. Since a connecting rod is fixed on the rotating plate, the two ends of the connecting rod can rotate in the support blocks fixed on both sides of the junction box when the rotating plate rotates. After the box cover is rotated, the interior of the junction box can be in an open state. After the connecting wires of the motor body are combed, a tool is used to fix the frame to the position of the motor body near the bottom of the junction box, and then the terminal is installed on the frame for fixing. When the terminal is fixed, the connecting wires of the motor body can be installed and connected with it, thereby facilitating improving the use efficiency of the junction box.

[0013] (3) The present invention discloses a permanent magnet motor for a CNC machine tool that is easy to disassemble. After the junction box is installed, the limiting mechanism is pulled and the box cover is rotated, so that the motor drives the rotating block fixed at the end to rotate into the interior of the installation block. When the limiting mechanism is released, the limiting mechanism can limit the rotating block, thereby facilitating the operator to quickly limit the box cover and also facilitating the operator to inspect the interior of the junction box. That is, the box cover is rotated to drive the rotating block fixed at the end to rotate, and then the pull rings provided on both sides of the installation block are manually moved. When the pull ring drives the stop block to slide in the direction away from the through groove, the stop block can be made to move. The sliding rod fixed on the top drives the butt plate to slide, and the telescopic spring fixed on the end is squeezed when the butt plate slides. When the telescopic spring is in a compressed state, the end of the butt plate can be moved from the through-slot position to the inside of the mounting block; after the rotating block rotates to the through-slot position, the pull ring is released, and under the reaction force of the telescopic spring, the sliding rod can drive the butt plate to reset, and then the butt block can slide along the top of the rotating block, so as to facilitate the limiting of the rotating block, so that the box cover and the junction box are in a fitted state, thereby facilitating the inspection of the inside of the junction box and reducing the tedious steps of disassembling and installing the box cover during inspection.

[0029] Specifically, the limiting mechanism 9 includes a stopper 902 and a pull ring 903, the mounting block 7 is in contact with the stopper 902, the stopper 902 is fixed with a pull ring 903 and a slide bar 907, the slide bar 907 is in contact with a stopper plate 904, the stopper plate 904 is fixedly installed with a telescopic spring 906 at the end close to the stopper plate 902, the telescopic spring 906 is fixedly connected to the mounting block 7, the stopper plate 904 is slidably connected to the rotating block 8, the mounting block 7 is rotatably connected with a roller 905, and a through groove 90 is provided in the mounting block 7. 1, the height of the stop block 902 is greater than the distance between the two slide bars 907, the slide bar 907 is slidably connected to the mounting block 7, the two groups of rollers 905 are symmetrically arranged, and the rollers 905 are rollingly connected to the stop plate 904, the width of the through slot 901 is greater than the width of the rotating block 8, and the through slot 901 is rotated with the rotating block 8. After the junction box 4 is installed, the limiting mechanism 9 is pulled and the box cover 5 is rotated to drive the rotating block 8 fixed at the end to rotate into the mounting block 7. When the limiting mechanism 9 is released, it can be rotated to the rotating block 8 The box cover 5 is limited in position, so that it is convenient for the operator to quickly limit the position of the box cover 5 and to inspect the inside of the junction box 4, that is, the box cover 5 is rotated to drive the rotating block 8 fixed at the end to rotate, and then the pull rings 903 set on both sides of the installation block 7 are manually moved. When the pull rings 903 drive the block 902 to slide in the direction away from the through groove 901, the sliding rod 907 fixed on the block 902 can drive the plate 904 to slide. When the plate 904 slides, it squeezes the telescopic spring 906 fixed at the end. When the telescopic spring 906 is in When in the compressed state, the end of the abutment plate 904 can be moved from the through slot 901 to the inside of the mounting block 7; after the rotating block 8 is rotated to the through slot 901, the pull ring 903 is released, and under the reaction force of the telescopic spring 906, the slide bar 907 can drive the abutment plate 904 to reset, and then the abutment block 904 can slide along the top of the rotating block 8, thereby facilitating the limiting of the rotating block 8, so that the box cover 5 and the junction box 4 are in a fitted state, thereby facilitating the inspection of the inside of the junction box 4 and reducing the cumbersome steps of disassembling and assembling the box cover 5 during inspection.

[0030] Specifically, the connecting mechanism 6 includes a rotating plate 601 and a connecting rod 602. The rotating plate 601 is fixedly installed at one end of the box cover 5 away from the rotating block 8. The connecting rod 602 is fixedly connected to the rotating plate 601. The terminal box 4 is fixedly connected to a support block 603. The connecting rod 602 and the support block 603 are rotatably connected. A frame 604 is mounted on the bottom end of the terminal box 4. A terminal 605 is fixed on the frame 604. The two support blocks 603 are symmetrically arranged. The terminal box 4 is in conflict with the box cover 5. The box cover 5 is rotated to drive the connecting mechanism 6 to rotate, so that the terminal box 4 is in an open state, which is convenient for the operator to install and fix the connecting wires of the motor body 1, that is, fix the motor body 1 After that, the operator can place the junction box 4 on the top of the motor body 1, and then rotate the box cover 5, so that the box cover 5 can drive the rotating plate 601 to rotate. Since the rotating plate 601 is fixed with a connecting rod 602, the two ends of the connecting rod 602 can rotate in the support blocks 603 fixed on both sides of the junction box 4 when the rotating plate 601 rotates. After the box cover 5 is rotated, the interior of the junction box 4 can be in an open state. After the connecting wires of the motor body 1 are combed, use tools to fix the frame 604 at a position of the motor body 1 near the bottom of the junction box 4, and then install the terminal 605 on the frame 604 for fixing. When the terminal 605 is fixed, the connecting wires of the motor body 1 can be installed and connected with it, thereby improving the use efficiency of the junction box 4.

[0031] Specifically, the support mechanism 2 includes a fixed base 201 and a clamping block 205. The fixed base 201 is installed at the bottom end of the motor body 1, and the clamping block 205 and the support frame 203 are fixedly installed on the fixed base 201. Two groups of clamping plates 202 are fixedly connected to the support frame 203, and a clamping slot 206 is provided on the clamping plate 202. A fixed block 204 is fixedly connected to the motor body 1, and the clamping block 205 is clamped and installed in the clamping slot 206. The support frame 203 is arranged in an L-shaped structure, and the two groups of clamping plates 202 are symmetrically arranged.

[0032] Specifically, the fixing mechanism 3 includes a bed 301 and a limit block 302. The top of the motor body 1 is fixedly connected to the limit block 302. The limit block 302 is snap-connected with the bed 301. The bed 301 is provided with a limit groove 303 and a through hole 304. The limit groove 303 is snap-fitted with the limit block 302. The through hole 304 is snap-fitted with the motor body 1. The motor body 1 is fixed to the support mechanism 2, and then the support mechanism 2 is snap-fitted into the fixing mechanism 3. , which makes it easier to quickly install the motor body 1 on the machine tool, thereby preventing the motor body 1 from being offset during the disassembly and assembly process, that is, when the operator installs the fixed base 201 provided at the bottom end of the motor body 1 on the support frame 203, the operator can first engage the fixed block 205 on the fixed base 201 with the slot 206 provided between the two card plates 202. Since the slot 206 and the block 205 have the same shape, when the fixed base 201 is on the top of the support frame 203, When the end slides, the block 205 can slide in the slot 206 with the fixed base 201. The setting of the slot 206 can prevent the position of the fixed base 201 from being displaced after the motor body 1 is used for a long time; bolts are installed on the fixed base 201 and the support frame 203 using tools, so as to facilitate the fixed base 201 to be limited; when the support frame 203 is fixed on the bed 301, the limit block 302 fixed at the top of the motor body 1 can be first engaged with the limit slot 303 provided on the bed 301. When the limit block 302 conflicts with the inner wall of the bed 301, the limit block 302 can be limited. At this time, the output shaft of the motor body 1 passes through the bed 301 through the through hole 304 provided on the bed 301, and then the support frame 203 can be firmly installed on the side wall of the bed 301 through the fixing bolts, so that it is convenient for the operator to quickly fix the motor body 1 and prevent the motor body 1 from having errors in position after disassembly and assembly.

[0033] When the present invention is in use, first, when the operator installs the fixed base 201 provided at the bottom end of the motor body 1 onto the support frame 203, the operator can first engage the fixed block 205 on the fixed base 201 with the slot 206 provided between the two card plates 202. Since the slot 206 and the block 205 have the same shape, when the fixed base 201 slides on the top end of the support frame 203, the block 205 can slide along with the fixed base 201 in the slot 206. The slot 206 can prevent the position of the fixed base 201 from being displaced after the motor body 1 is used for a long time. Bolts are installed on the fixed base 201 and the support frame 203 using tools. This makes it easier to position the fixed base 201. When the support frame 203 is fixed to the bed 301, the limit block 302 fixed on the top of the motor body 1 can be first engaged with the limit groove 303 provided on the bed 301. When the limit block 302 conflicts with the inner wall of the bed 301, the limit block 302 can be limited. At this time, the output shaft of the motor body 1 passes through the bed 301 through the through hole 304 provided on the bed 301. Then, the support frame 203 can be firmly installed on the side wall of the bed 301 through the fixing bolts, so that it is convenient for the operator to quickly fix the motor body 1 and prevent the motor body 1 from having an error in position after disassembly and assembly.

[0034] After fixing the motor body 1, the operator can place the junction box 4 on the top of the motor body 1, and then rotate the box cover 5, so that the box cover 5 can drive the rotating plate 601 to rotate. Since the rotating plate 601 is fixed with a connecting rod 602, both ends of the connecting rod 602 can rotate in the support blocks 603 fixed on both sides of the junction box 4 when the rotating plate 601 rotates. After the box cover 5 is rotated, the inside of the junction box 4 can be in an open state. After the connecting wires of the motor body 1 are combed, the frame 604 is fixed to the position of the motor body 1 near the bottom of the junction box 4 with a tool, and then the terminal 605 is installed on the frame 604 for fixing. When the terminal 605 is fixed, the connecting wires of the motor body 1 can be installed and connected with it, so as to improve the use efficiency of the junction box 4.

[0035] When the cam 904 is in a state of being compressed, the end of the plate 904 can be moved from the through slot 901 to the inside of the mounting block 7; after the rotating block 8 is rotated to the through slot 901, the pull ring 903 is released, and under the reaction force of the telescopic spring 906, the slide bar 907 can drive the plate 904 to reset, thereby making the plate 904 slide along the top of the rotating block 8, thereby facilitating the limiting of the rotating block 8, so that the cover 5 and the junction box 4 are in a fitting state, thereby facilitating the inspection of the inside of the junction box 4 and reducing the tedious steps of disassembling and assembling the cover 5 during inspection.
