[0002] Linear motors can directly convert electrical energy into linear motion mechanical energy without the need for intermediate transmission links, and have high-precision, high-speed and high-acceleration motion characteristics. They mainly include stators and movers. Under the combined action of induced current and magnetic field, longitudinal electromagnetic thrust will be generated. When the stator remains fixed, the mover will move linearly along the direction of the traveling wave magnetic field.

[0003] The mover mainly includes an iron core and a coil. When current passes through the coil, the coil will generate some heat, and eddy currents will be induced in the iron core, causing heat.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Refer to the instruction manual Figure 1-Figure 13 A linear motor with a heat dissipation structure includes a slide rail 1, a stator 2 is fixedly installed at the bottom of the slide rail 1, a protective cover 11 is installed at the upper end of the slide rail 1, a mover assembly 3 is slidably installed on the slide rail 1, the mover assembly 3 includes a slide seat 31, the slide seat 31 is slidably set on the slide rail 1, an iron core 32 is fixedly installed at the bottom of the mover assembly 3, and a plurality of coils 33 are set at the bottom of the iron core 32.

[0034] The core 32 is provided with a plurality of cooling holes 321, and cooling pipes 4 are arranged in the plurality of cooling holes 321. The cooling pipes 4 include a plurality of straight pipes 41, and the plurality of straight pipes 41 are inserted into the interior of the cooling holes 321; the cooling pipes 4 also include a plurality of curved pipes 42, and the plurality of curved pipes 42 sequentially connect the plurality of straight pipes 41 end to end to form a serpentine structure, and the first and the last straight pipes 41 are respectively connected to the water inlet pipe 43 and the water outlet pipe 44. There is a side gap 10 between the slide rail 1 and the protective cover 11, and the water inlet pipe 43 and the water outlet pipe 44 extend outward from the position of the side gap 10.

[0035] The inner surface of the bottom of the cooling hole 321 is adapted to the shape of the outer surface of the bottom of the straight tube 41 and can fit together. When the cooling hole 321 fits together with the straight tube 41, there is a gap 322 between the upper surface inside the cooling hole 321 and the outer surface of the upper part of the straight tube 41. The inner surface of the bottom of the cooling hole 321 and the outer surface of the bottom of the straight tube 41 and the inside of the gap 322 are filled with heat dissipation silicone grease.

[0036] In the above technical solution, the cooling hole 321 is a long groove structure. When the straight tube 41 is inserted into the middle of the cooling hole 321, the left and right sides of the straight tube 41 fit with the side walls of the cooling hole 321, and the upper surface and lower surface of the straight tube 41 respectively form a gap 2 323 and a gap 324 with the upper surface and lower surface of the cooling hole 321.

[0037] In this embodiment, if Figure 6 , Figure 8 and Fig.12 As shown, a side stop assembly 5 is provided at one end of the straight tube 41, and the side stop assembly 5 includes a metal ring 51 and a metal sleeve 52 arranged in the middle of the metal ring 51. The metal ring 51 and the metal sleeve 52 are connected by a soft connecting ring 53. The metal sleeve 52 is fixedly sleeved on the end of the straight tube 41. The metal ring 51 and the metal sleeve 52 are both in contact with the side wall of the iron core 32, and the metal sleeve 52 blocks one end of the cooling through hole 321. The upper and lower sides of the metal sleeve 52 are fixedly connected with hoses 54. The two hoses 54 are respectively used to communicate with the gap 2 323 and the gap 324.

[0038] In this embodiment, if Figure 7 , Figure 8 and Fig.12 As shown, a side block assembly 6 is provided at the other end of the straight pipe 41. The side block assembly 6 includes a metal ring 61 and a soft connection sleeve 62 arranged in the middle of the metal ring 61. The metal ring 61 and the soft connection sleeve 62 are fixedly connected. The soft connection sleeve 62 is fixedly sleeved on the end of the straight pipe 41, and the soft connection sleeve 62 is pressed on the end of the cooling through hole 321.

[0039] In this embodiment, the cooling through hole 321 is set to a long groove structure, and a gap 2 323 and a gap 324 are formed, the purpose of which is to enable the straight tube 41 to be inserted into the interior of the cooling through hole 321 and then filled with heat dissipation silicone grease. If the cooling through hole 321 is set to the same cross-sectional shape as the straight tube 41, then when the straight tube 41 is inserted into the interior of the cooling through hole 321, the straight tube 41 will squeeze out the silicone grease, which may cause insufficient silicone grease filling in some parts, and the silicone grease will also enter from the end of the straight tube 41. After assembly, the straight tube 41 needs to be cleaned, which is more troublesome. This embodiment can effectively avoid the above problems by inserting the straight tube 41 first and then filling it with heat dissipation silicone grease.

[0040] In this embodiment, the straight tube 41 is divided into two parts, a half tube 1 411 and a half tube 2 412 , so that the straight tube 41 can be easily inserted into the cooling through hole 321 .

[0041] In this embodiment, during the specific operation, the half pipe 1 411 and the half pipe 2 412 are first inserted into the cooling through hole 321 from both ends of the cooling through hole 321, and then plugged together. At this time, the straight pipe 41 is located in the middle of the cooling through hole 321, and the gap 2 323 and the gap 324 are formed (such as Fig.10 As shown in the left figure), the metal ring 1 51 and the metal sleeve 52 are tightly attached to the iron core 32, and the flexible connection sleeve 62 is also attached to the iron core 32. Then, heat dissipation silicone grease is injected from the hose 54 into the interior of the cooling through hole 321, specifically into the gap 2 323 and the gap 3 324. Inject from one of the hoses 54, such as selecting the lower hose 54 to inject the heat dissipation silicone grease. During the injection process, the gas squeezes the flexible connection sleeve 62 to deform the flexible connection sleeve 62. In this way, at the position of the flexible connection sleeve 62, the gap 2 323 and the gap 324 are connected, and the air will be discharged from the gap 324 through the upper hose 54. Similarly, the heat dissipation silicone grease injected from the bottom also enters the gap 2 323 from the position of the flexible connection sleeve 62 until the gap 2 323 is filled and overflows from the upper hose 54. After the filling is completed, press down the straight tube 41 so that the inner surface of the bottom of the cooling through hole 321 fits with the outer surface of the bottom of the straight tube 41 (as shown in the figure below). Fig.10 As shown in the right figure), at this time, the silicone grease inside the gap three 324 also flows from the position of the soft connection sleeve 62 to the gap two 323. In this way, the installation of the straight pipe 41 and the filling of the heat dissipation silicone grease are completed. Then, the straight pipes 41 are connected end to end in sequence using the curved pipe 42 to form a serpentine structure, and the water inlet pipe 43 and the water outlet pipe 44 are connected to the first and last straight pipes 41 respectively.

[0042] The above technical solution sets the cooling through hole 321 into a long groove-shaped structure, so that after the straight tube 41 is inserted into the interior of the cooling through hole 321, a gap 2 323 and a gap 324 can be formed, so that the heat dissipation silicone grease can be filled after the straight tube 41 is inserted. When the straight tube 41 is pressed down to fit the cooling through hole 321, the heat dissipation silicone grease can fill the gap between the straight tube 41 and the cooling through hole 321 without the situation of insufficient filling.

[0043] Refer to the instruction manual Figure 6 , Figure 7 and Fig.13 As shown, one end of the slide 31 is fixedly connected to a positioning plate 7, and the lower side of the positioning plate 7 has a plurality of pressure forks 71, each group of pressure forks 71 presses the metal sleeve 52 onto the iron core 32, thereby limiting the displacement of the metal sleeve 52 in the X-axis direction.

[0044] Furthermore, the other end of the slide seat 31 is fixedly connected with a positioning piece 2 8 , and the lower side of the positioning piece 2 8 has a plurality of groups of pressing forks 2 81 , and each group of pressing forks 2 81 presses the metal ring 2 61 onto the iron core 32 .

[0045] Furthermore, a positioning column 1 3201 and a positioning column 2 3202 are fixedly connected at both ends of the slide seat 31 and at the upper and lower positions of the end of the cooling through hole 321 , respectively. The metal ring 1 51 is sleeved on the positioning column 1 3201 , and the metal ring 2 61 is sleeved on the positioning column 2 3202 .

[0046] It should be noted that when installing the side stopper assembly 1 5 and the side stopper assembly 2 6, first install the side stopper assembly 1 5 and the side stopper assembly 2 6 on the half pipe 1 411 and the half pipe 2 412 respectively, then after the half pipe 1 411 and the half pipe 2 412 are inserted into the cooling through hole 321, the metal ring 1 51 is sleeved on the positioning column 1 3201, and the metal ring 2 61 is sleeved on the positioning column 2 3202 for positioning, and then the positioning piece 1 7 and the positioning piece 2 8 are installed, and the positioning piece 1 7 and the positioning piece 2 8 are fixed to the two ends of the slide seat 31, so that the pressure fork 1 71 presses the metal sleeve 52 on the iron core 32 to limit the displacement of the metal sleeve 52 in the X-axis direction, and the pressure fork 2 81 presses the metal ring 2 61 on the iron core 32. Among them, the pressure fork 1 71 presses the metal sleeve 52 while also pressing the metal ring 1 51. In this way, the metal ring 1 51 and the metal ring 2 61 can no longer move.

[0047] Furthermore, if Figure 4 and Figure 5 As shown, a lower pressing frame 9 is arranged on the slide 31, and the lower pressing frame 9 includes a pressing plate 1 91 and a pressing plate 2 92 respectively arranged at the two ends of the iron core 32, and the pressing plate 1 91 and the pressing plate 2 92 are respectively used to press down the two ends of the straight tube 41, and a sliding rod 93 is connected between the pressing plate 1 91 and the pressing plate 2 92, and a sliding groove 311 is opened on the slide 31, and the sliding rod 93 slides vertically inside the sliding groove 311, and a fastener 90 is arranged on the slide 31, and the fastener 90 is used to fix the sliding rod 93 on the slide 31.

[0048] Furthermore, the bottoms of several groups of pressure forks 71 are fixedly connected with fixed blocks 100, and a pressure belt 101 passes through all the fixed blocks 100. The bottom of the pressure plate 91 has several extension plates 911, and the extension plates 911 are used to press the pressure belt 101 downward so that the pressure belt 101 presses the hose 54 upward onto the straight tube 41.

[0049] It should be noted that after the heat dissipation silicone grease is filled, when the straight tube 41 is pressed down, the fastener 90 is screwed downward, the fastener 90 presses down the slide bar 93, the lower pressing frame 9 moves downward, and the pressing plate 1 91 and the pressing plate 2 92 respectively press down the two ends of the straight tube 41. At this end of the side stop assembly 1 5, the metal ring 1 51 remains stationary, the straight tube 41 drives the metal sleeve 52 to move downward, and the soft connection ring 53 is deformed. At this end of the side stop assembly 2 6, the metal ring 2 61 remains stationary, and the straight tube 41 drives the soft connection sleeve 62 to deform.

[0050] The fixed block 100 is an arc-shaped structure, and the two ends of the pressing belt 101 are respectively fixed to the fixed blocks 100 at the two ends. When the pressing plate 91 and the extension plate 911 move downward, the extension plate 911 squeezes the pressing belt 101 downward, and the pressing belt 101 located inside the fixed block 100 deforms upward, so that the hose 54 located below can be pressed upward on the outer surface of the straight tube 41, and the upper hose 54 is pressed on the outer surface of the straight tube 41 by the pressing plate 91, thereby preventing the heat dissipation silicone grease inside the cooling through hole 321 from flowing out from the two hoses 54. In addition, before moving the pressing plate 91 downward, the two hoses 54 can be clamped with a tool to prevent the heat dissipation silicone grease from flowing out from the two hoses 54 when the straight tube 41 moves downward. Among them, the soft connection ring 53 and the soft connection sleeve 62 are both made of elastic rubber, and the fastener 90 is a fastening screw.

[0051] The above technical scheme can press down the straight tube 41 through the setting of the positioning plate 1 7, the positioning plate 2 8 and the pressing frame 9. On the one hand, when the straight tube 41 is pressed down, the soft connection ring 53 and the soft connection sleeve 62 can be deformed according to the position of the straight tube 41. The purpose of this setting is: in order to enable the straight tube 41 to be located in the middle position of the cooling through hole 321 when inserted into the cooling through hole 321, the positioning column 1 3201 and the positioning column 2 3202 are used for positioning. When the straight tube 41 is pressed down, since the metal ring 1 51 and the metal ring 2 61 cannot move, the deformable soft connection ring 53 and the soft connection sleeve 62 are provided to adapt to the movement of the straight tube 41, thereby facilitating positioning and facilitating the downward movement of the straight tube 41.

[0052] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
