Description

Technical Field

[0001] The present invention relates to the technical field of linear motor assemblies, and specifically to a replaceable linear motor assembly. Background Art

[0002] A linear motor, also known as a linear induction motor, is widely used in industrial equipment. When used on a machining machine tool, it can drive a workbench or a tool to perform high-precision linear motion to achieve the machining of parts. Compared with the traditional driving method of a rotary motor plus a ball screw, it can reduce the errors and inertia brought by mechanical transmission links and improve the machining accuracy and speed.

[0003] When the motor assembly is in use, in order to reduce the friction between the slider and the slide rail, rollers are usually installed at the bottom of the slider to reduce the friction. However, in the existing slide rail assembly, the rollers at the bottom of the slider lack a separate lubrication device. When the linear motor runs for a long time, if the rollers at the bottom of the slider are not lubricated, the direct contact friction between the rollers and the slide rail will increase, accelerating the wear of the rollers and the slide rail, and affecting the subsequent use accuracy of the linear motor assembly. At the same time, in the linear motor assembly, when the slider runs in the slide rail for a long time, depressions or protrusions usually appear inside the slide rail. However, in the existing linear motor assembly, there is a lack of a detection mechanism for the slide rail. If depressions or protrusions appear inside the slide rail and the slider still runs inside the slide rail, the movement trajectory of the slider will change, resulting in a decrease in the positioning accuracy of the linear motor assembly. When the linear motor assembly is used for a long time, the magnetism of the permanent magnet block inside it will naturally decay over time. If it is not replaced in time, negative effects such as reduced thrust and decreased positioning accuracy will occur. To ensure the stable performance of the motor, the permanent magnet usually needs to be replaced regularly. However, the existing permanent magnet blocks are all installed in the assembly by bolts, and the disassembly and replacement are relatively troublesome. Summary of the Invention

Pressing springs 28 are fixedly connected to the outer side walls of the upper plate 21 and the lower plate 19, and the other ends of the pressing springs 28 are fixedly connected to the inner side walls of the limit groove 27. Fixed teeth 29 are fixedly connected to both sides of the upper plate 21 and the lower plate 19. A plurality of sliding grooves are opened on both sides of the installation frame 14, and blocking members 30 corresponding to the fixed teeth 29 are slidably arranged inside the plurality of sliding grooves.

[0037] A pull rod 31 is fixedly connected to the outer side wall of the blocking member 30. A compression spring 32 is sleeved on one side of the pull rod 31 located inside the sliding groove. A plurality of push rods 16 are slidably connected inside the installation frame 14 (as Figure 4 shown). The bottom ends of the plurality of push rods 16 are rotatably connected with flaw detection wheels 15. The plurality of push rods 16 respectively pass through the middle of the lower plate 19 and the upper plate 21. Pulling springs 17 are fixedly connected to the outer side walls of the plurality of push rods 16, and the other ends of the pulling springs 17 are fixedly connected to the inner side wall of the installation frame 14.

[0038] An upper convex block 20 and a lower convex block 18 are respectively fixedly connected to the outer side wall of the push rod 16. The upper convex block 20 contacts the outer wall of the upper plate 21, and the lower convex block 18 contacts the outer wall of the lower plate 19.

[0039] Rolling grooves 13 are opened inside the sliders 12. The rolling grooves 13 run through the inside of the sliders 12. A limit block 23 is fixedly connected to the outer side wall of the upper plate 21. The limit block 23 slidably penetrates into the inside of the rolling groove 13. Side rails 26 are opened on both sides inside the installation frame 14. A hook pulling convex block 24 is slidably connected inside the side rail 26.

A connecting rod 22 is fixedly connected to the outer side wall of the lower plate 19. The upper end of the connecting rod 22 and the side wall of the hook pulling convex block 24 are respectively meshed with the gear 25.

[0040] An insertion box 37 is fixedly connected inside the slide rail 5. The end of the insertion box 37 is provided with a limit turning shaft 40 (as Figure 11 shown). A hook plate 39 is arranged on the limit turning shaft 40 (it should be noted that a positioning pin is built in the limit turning shaft 40. When the limit turning shaft 40 turns more than ninety degrees, the positioning pin will block the limit turning shaft 40). A runner 38 is rotatably connected inside the insertion box 37. Contact sensors are arranged on one side of the hook plate 39 close to the runner 38 and inside both the limit block 23 and the hook pulling convex block 24. A temperature reduction and lubrication mechanism is arranged on the runner 38.

[0041] In this embodiment, during use, if the permanent magnet block 4 needs to be replaced, only need to press the self-locking plug 9 previously inserted into the bayonet 7 outside the bayonet 7, so that the self-locking plug 9 contracts into the plug 8 until it is disengaged from the fixation of the bayonet 7. At this time, the plug 8 can be pulled out from the fixed slot 6 to replace the permanent magnet block 4. After the permanent magnet block 4 is replaced, align the plug 8 and insert it into the fixed slot 6. When the plug 8 is inserted, the inner wall of the fixed slot 6 will push the self-locking plug 9 to contract into the plug 8 along the contact bevel of the self-locking plug 9 until the bottom of the plug 8 touches the bottom of the fixed slot 6. At this time, under the elastic force of the return spring 10, the self-locking plug 9 will be inserted into the bayonet 7 to complete the installation of the permanent magnet block 4. The speed of the entire replacement and installation is simpler and faster compared to the traditional bolt installation, greatly improving the replacement and repair efficiency of the assembly.

[0042] After the replacement and installation of the permanent magnet block 4 are completed, the magnetic field inside the motor main body 11 can be controlled to make it move inside the slide rail 5 through the slider 12 under the action of the magnetic attraction of the permanent magnet block 4. At the same time, by controlling the direction of the magnetic field inside the permanent magnet block 4, the slider 12 can be controlled to move linearly back and forth inside the slide rail 5. (This is the prior art and will not be elaborated too much).

[0043] Embodiment Two: Please refer to Figure 1 - Figure 16 , the temperature reduction and lubrication mechanism includes a swing arm 48 rotatably connected to the runner 38 (as Figure 13 shown), and a spray tube 47 is arranged inside the plug box 37.

[0044] A piston rod 45 is slidably connected through the inside of the spray tube 47, and the other end of the swing arm 48 is rotatably connected to the outside of the piston rod 45. Two spray pipes 46 are communicated inside the spray tube 47, and a plurality of spraying holes 41 are opened on both spray pipes 46.

[0045] A flow-through box 49 is arranged on the oil suction pipe 42, a baffle 50 is slidably connected inside the flow-through box 49, a through hole 51 is opened on the baffle 50, and electric telescopic rods 52 are fixedly connected to both sides of the baffle 50. The other ends of the electric telescopic rods 52 are fixedly connected to the outer side wall of the flow-through box 49.

[0046] A plurality of rollers 33 are arranged at the bottom of the slider 12 (as Figure 8 shown), a plurality of lubrication ports 34 corresponding to the plurality of rollers 33 are opened inside the slider 12, and inner groove openings 35 are opened on both sides of the rolling groove 13 (as Figure 3 shown), and the inner groove openings 35 are communicated with the plurality of lubrication ports 34.

[0047] In this embodiment, when the slider 12 drives the motor main body 11 to move to the end of the slide rail 5, i.e., the fuel tank 44, the plug box 37 will be inserted into the rolling groove 13 during the movement of the slider 12. When the plug box 37 is inserted into the rolling groove 13, the runner 38 inside the plug box 37 will contact the inner wall of the rolling groove 13 and rub the runner 38 to roll. When the runner 38 rotates, it will push the piston rod 45 to perform a reciprocating suction movement inside the spray tube 47 through the swing arm 48. When the piston rod 45 performs a reciprocating suction movement inside the spray tube 47, the suction pipe 43 will suck the air that has been processed inside the air storage tank 36 into it, and then spray it into the inner notch 35 through the multiple spraying holes 41 on the plug box 37. Finally, it will cool the roller 33 through the lubrication port 34 to prevent the roller 33 from getting hot due to long-term rolling, ensuring that the entire motor assembly system can operate stably. When the slider 12 reciprocates inside the slide rail 5, the multiple flaw detection wheels 15 located inside the mounting frame 14 will also move with the slider 12 and make rolling contact with the surface of the slide rail 5. When the flaw detection wheel 15 contacts the surface of the slide rail 5, there are three situations;

[0048] First, when the surface of the slide rail 5 is flat without depressions or protrusions, the position of the push rod 16 will not change at this time. According to the above principle, when the plug box 37 is inserted into the rolling groove 13, it can also be freely pulled out;

[0049] The second type is that when the surface of the slide rail 5 is concave and the flaw detection wheel 15 moves to the concave position with the slider 12, since the support point of the concave position of the slide rail 5 is lower than that of the flat position, at this time, under the tension of the tension spring 17, the push rod 16 located at the concave position will move downward inside the mounting frame 14. When the push rod 16 located at the concave position moves downward, it will pull the lower plate 19 downward together through the lower protrusion 18. When the lower plate 19 moves downward, the fixed tooth 29 near the lower plate 19 will move downward together. Since the contact edge of the fixed tooth 29 is provided with a plurality of triangular teeth, when the lower plate 19 pushes the corresponding fixed tooth 29 to move downward together, the blocking member 30 will continuously contact the triangular tooth edge until it reaches the specified position. The blocking member 30 will abut against the right-angled side of the triangular tooth, thereby limiting it, so that the lower plate 19 cannot move up autonomously. When the lower plate 19 moves downward, it will pull the connecting rod 22 to move downward synchronously. Under the action of the gear 25, when the connecting rod 22 When the connecting rod 22 moves downward, the gear 25 pushes the hook-pull protrusion 24 upward until it moves into the rolling groove 13. At this time, when the plug box 37 is inserted into the rolling groove 13, the hook plate 39 at the end of the plug box 37 contacts the hook-pull protrusion 24 and, under the push of the hook-pull protrusion 24, turns 90 degrees toward the direction close to the rotating wheel 38 until it passes over the hook-pull protrusion 24. When the slider 12 drives the rolling groove 13 to move away from the plug box 37, the plug box 37 is removed from the rolling groove. When the motor body 11 and the slider 12 are pulled out, the hook plate 39 will contact with the hook-pull projection 24. Since the limit flip shaft 40 can only flip ninety degrees, when the hook plate 39 contacts with the hook-pull projection 24, the hook plate 39 that is no longer flipped will hook the hook-pull projection 24. Therefore, the plug-in box 37 will hook the entire motor body 11 and the slider 12, stop the movement of the motor body 11 and the slider 12, and prevent the slider 12 from continuing to perform linear motion in the uneven slide rail 5, resulting in increased wear of the slider 12.

[0050] The third method is that when a bulge appears on the surface of the slide rail 5, the flaw detection wheel 15 moves to the bulge with the slider 12. Since the support point of the bulge of the slide rail 5 is higher than that of the flat part, the push rod 16 located at the bulge will be lifted up. When the push rod 16 located at the bulge moves up, it will push the upper plate 21 to move up together through the upper protrusion 20. When the upper plate 21 moves up, the fixed teeth 29 near the upper plate 21 will move up together. Similar to the above principle, when the upper plate 21 pushes the corresponding fixed teeth 29 to move up together, the push rod 16 located at the bulge will be lifted up. The blocking member 30 near the upper plate 21 will continuously contact the triangular tooth edge until it reaches the specified position. The blocking member 30 will abut against the right-angled side of the triangular tooth to limit it, so that the upper plate 21 cannot move downward on its own. When the upper plate 21 moves upward, it will push the limiting block 23 into the rolling groove 13. When the subsequent plug-in box 37 is inserted into the rolling groove 13, the hook plate 39 at the end of the plug-in box 37 will contact the limiting block 23 and, under the push of the limiting block 23, turn 90 degrees toward the direction close to the rotating wheel 38 (refer to Figure 15), until it passes over the limit block 23. When the slider 12 drives the rolling groove 13 to move away from the plug box 37, the plug box 37 is pulled out from the rolling groove 13, and the hook plate 39 will contact the limit block 23. Since the limit flip shaft 40 can only flip ninety degrees, when the hook plate 39 contacts the limit block 23, the hook plate 39 that is no longer flipped will hook the limit block 23. Therefore, the plug box 37 will hook the entire motor body 11 and the slider 12 again, stop the movement of the motor body 11 and the slider 12, and prevent the slider 12 from being aggravated by wear, which affects the use accuracy of the entire linear motor.

[0051] During use, if the slider 12 needs to perform violent linear movement, the slider 12 will perform rapid reciprocating movement on the slide rail 5. At this time, when the plug box 37 is inserted into the rolling groove 13, the electric telescopic rod 52 can be contracted to allow the through hole 51 to enter the circulation box 49. When the through hole 51 enters the circulation box 49, the oil extraction pipe 42 will suck the lubricating oil in the oil storage tank 44 into the inside of the spray barrel 47, and then spray it into the inner groove 35 through multiple spray holes 41. Finally, the roller 33 is lubricated through the lubrication port 34, thereby reducing the friction contact between the high-speed rotating roller 33 and the slide rail 5, extending the service life of the entire roller 33 and the slide rail 5, and making the entire assembly more accurate to use.

[0052] It should be noted that when the hook plate 39 hooks the limit block 23 or the hook-pull protrusion 24, the sensor on the side of the hook plate 39 close to the rotating wheel 38 will contact the sensor inside the limit block 23 or the hook-pull protrusion 24. When the sensor contacts, an alarm will be issued to remind the operator to stop the movement of the slider 12 in time and replace the slide rail 5 (this is the prior art and will not be elaborated in detail).

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
