Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of linear motors, and more specifically, to a guide rod and vertical roller combined transmission type linear motor module. Background Art
[0002] The linear motor is a traditional cylindrical motor that is stretched and straightened to change the primary closed magnetic field into an open magnetic field. The stator part of the rotary motor becomes the primary of the linear motor, and the rotor part of the rotary motor becomes the secondary of the linear motor. If the primary is fixed, the secondary can move linearly along the direction of the traveling magnetic field. This can realize the direct drive feed mode of the linear motor of the high-speed machine tool, and the primary and secondary of the linear motor are directly installed on the workbench and bed of the high-speed machine tool respectively.
[0003] The main structure of a linear motor consists of a stator and a mover. The stator can be composed of windings or permanent magnets. The windings can generate a magnetic field through current, and the permanent magnets can provide a constant magnetic field without the need for external current. Sometimes, the stator also contains an iron core to enhance the strength and directionality of the magnetic field. The mover is usually equipped with coils or conductor bars. The coils can generate electromagnetic force in the magnetic field of the stator to move the mover, and the conductor bars can interact with the magnetic field of the stator through electromagnetic induction.
[0004] When current passes through the stator winding or the mover coil, the electromagnetic force causes the mover to generate a driving force in the magnetic field generated by the stator. This force causes the mover to move in a straight line, forming a linear drive.
[0005] In a linear motor module, in order to improve the stability and accuracy of the movement of the mover, a guide rail structure is usually set between the slide and the guide base. For example, the linear motor modules currently on the market have a linear guide pair between the slide and the guide base as a transmission guide component. The linear guide pair is a precision-machined component, mainly imported products, and accounts for a large proportion of the cost of the entire linear motor module, which leads to an increase in the production cost of the linear motor module. Secondly, these linear guide pairs mainly rely on the guide rail itself to provide support, or use the ball set in the slider to provide support. When the linear motor module needs to carry a heavier load, the pressure between the slide and the guide base is relatively large. At this time, the ball bearing force is not high, and only relying on the contact between the slider and the guide rail to provide support will cause greater wear and reduce the service life and use accuracy of the linear motor module. Summary of the invention

DETAILED DESCRIPTION
[0034] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0035] Refer to the instruction manual Figures 1 to 13 A guide rod and vertical roller combined transmission type linear motor module includes a guide base 1 and a slide 2, a stator 11 is installed in the guide base 1, a mover 21 is installed at the bottom of the slide 2, the mover 21 is adapted to the stator 11, and provides thrust for the movement of the slide 2, and an encoder is also provided on the guide base 1, wherein the stator 11 and the mover 21 are commonly used structures in linear motors, and their structural principles are also widely used existing technologies, so no further explanation is given in this embodiment.
[0036] Guide rods 3 are arranged on both sides of the guide base 1, and two groups of guide rods 3 are arranged on each side, and the two groups of guide rods 3 are distributed up and down. Guide plates 4 are arranged on both sides of the slide 2. A roller 41 is rotatably installed on one side of the guide plate 4 corresponding to the guide rod 3 through a roller installation shaft 43. The roller 41 is arranged vertically to form a vertical roller support, and an adapting groove 42 is arranged on the outer circumferential surface of the roller 41. The adapting groove 42 and the outer wall of the guide rod 3 are adapted to each other, that is, during actual installation, the roller 41 is arranged between the upper and lower groups of guide rods 3, the roller 41 and the guide rod 3 are rolling matched, and the guide rod 3 forms a guide for the roller 41. After the slide 2 carries the corresponding equipment The force of the slide 2 is basically applied to the roller 41, and the support between the roller 41 and the guide rod 3 is used to support the slide 2. During the movement of the slide 2, the roller 41 and the guide rod 3 below are mainly in rolling cooperation. Therefore, the wear between the roller 41 and the guide rod 3 is small, which can improve the load-bearing capacity and guiding accuracy of the linear motor module, and further improve the service life of the linear motor module. Compared with the linear guide pair in the prior art, the module has lower cost, and the roller 41 and the guide rod 3 can be produced in a standardized manner, which can reduce the production cost while ensuring the accuracy of the linear motor.
[0037] For the distribution and arrangement of the guide rod 3, please refer to the attached manual. Figures 1 to 6 That is, guide grooves 12 are provided on both sides of the guide base 1, and two groups of guide rods 3 are respectively arranged in the top wall and the bottom wall of the guide groove 12, and the guide rods 3 are embedded and installed in the guide base 1, wherein the guide rod 3 can be selected from a round rod structure, and a high hardness and high wear resistance structure (such as hard alloy steel, etc.) is used. Correspondingly, the adapter groove 42 is also set as an arc-shaped groove, which fits the outer surface of the guide rod 3 (it should be noted that the guide rod 3 can also adopt other shapes of rods, such as square, triangle, etc., and the adapter groove 42 corresponds to the shape of the specific guide rod 3). The guide rod 3 has a simple structure, a relatively simple processing technology, and a low production cost, and the roller 41 can directly adopt a standard part structure similar to a bearing. For example, refer to the attached manual Figure 7 The roller 41 includes an outer ring 411 and an inner ring 412, and a ball 413 is arranged between the outer ring 411 and the inner ring 412. The adapting groove 42 is formed on the outer circumferential surface of the outer ring 411, and the roller mounting shaft 43 is fixedly mounted on the guide plate 4, and the inner ring 412 is fixedly mounted on the roller mounting shaft 43. That is, in addition to the adapting groove 42 being arranged on the outer circumferential surface of the outer ring 411, the roller 41 referred to in this embodiment can be designed and manufactured according to a double-row angular contact bearing, a four-point angular contact bearing or other bearing structure, and form a standard part. That is, on the basis of the existing bearing production process and equipment, only a process of machining the adapting groove 42 outside the outer ring 411 is added, so that a high-precision adapting groove 42 can be produced, and there is no need to design and manufacture a set of production lines separately, so the production cost is low and the degree of standardization is high.
[0038] Based on the above implementation, this embodiment also provides a lubrication assembly 5 for the roller 41 and the roller mounting shaft 43 to further reduce the friction loss between the roller 41 and the guide rod 3. Figure 3 , Figure 8 and Fig. 9 Lubricating components 5 are provided at both ends of the roller 41. The lubricating components 5 are used to apply lubricating oil to the surface of the guide rod 3. Specifically, the lubricating component 5 includes an inward extension structure 51. The inward extension structure 51 is fixedly installed at the end of the guide plate 4. The inward extension structure 51 extends to the inside of the guide groove 12. The top and bottom of the inward extension structure 51 are provided with grooves adapted to the guide rod 3. An oil brushing structure 52 is installed in the groove. An oil storage cavity 53 is provided inside the inward extension structure 51. Lubricating oil is stored in the oil storage cavity 53. The oil brushing structure 52 is arranged in contact with the outer surface of the guide rod 3. An oil seepage structure 521 is also provided on the oil brushing structure 52. The oil seepage structure 521 is immersed in the lubricating oil.
[0039] Among them, both the oil brushing structure 52 and the oil seepage structure 521 are made of oil seepage materials. For example, the oil brushing structure 52 can be made of felt pads, brushes, etc., and the oil seepage structure 521 can be made of felt strips, cotton strips, etc. In actual use, the oil brushing structure 52 can move in accordance with the guide rod 3, and the lubricating oil in the oil storage cavity 53 can penetrate into the oil brushing structure 52 through the oil seepage structure 521. In the process of the inner extension structure 51 following the movement of the slide 2, the lubricating oil is applied to the surface of the guide rod 3, and each group of rollers 41 is located between the two groups of inner extension structures 51. Therefore, regardless of the slide The guide rod 3 can be pre-oiled in any direction the seat 2 moves, and the oil brushing structure 52 moves on the surface of the guide rod 3 to remove dust attached to the surface of the guide rod 3, thereby preventing dust from affecting the guide rod 3 and the adapter groove 42 and improving the service life of the device. In order to control the seepage rate of the lubricating oil, a structure for tightening the oil brushing structure 52 can be provided in the inner extension structure 51 to prevent the lubricating oil from flowing out quickly, and a replenishing pipe is provided on the inner extension structure 51 to regularly replenish the lubricating oil into the oil storage chamber 53 to ensure the normal use of the equipment.
[0040] In the above embodiment, although the roller 41 and the two groups of guide rods 3 can be precisely matched, in actual use, after the slide 2 is loaded and compressed, the roller 41 and the bottom guide rod 3 are in closer contact. Therefore, the upper guide rod 3 and the roller 41 are relatively loose. When the slide 2 moves, the roller 41 rolls relative to the bottom guide rod 3 and slides relative to the upper guide rod 3. Therefore, the relative friction between the upper guide rod 3 and the roller 41 is relatively large. Moreover, when placed normally, under the influence of gravity, the ability of the lubricating oil to seep downward is strong, that is, the actual oil discharge effect of the upper oil brushing structure 52 is poor. For this reason, the oil storage cavity 53 and the oil brushing structure 52 are also improved in this embodiment. For details, refer to the attached manual. Fig.10 and Fig.11The oil storage chamber 53 includes an upper chamber 531 and a lower chamber 532. The lower chamber 532 is arranged corresponding to the oil brushing structure 52 at the bottom of the inner extension structure 51. The upper chamber 531 is located above the lower chamber 532. The oil brushing structure 52 at the top of the inner extension structure 51 is arranged in two groups. The two groups of oil brushing structures 52 are arranged along the length direction of the guide rod 3, and the positions of the inner extension structure 51 corresponding to the two groups of oil brushing structures 52 at the top of the inner extension structure 51 are both provided with oil introduction chambers 533. Two groups of piston chambers 534 are arranged at the bottom of the upper chamber 531. The two groups of piston chambers 534 are respectively connected to the bottoms of the two groups of oil introduction chambers 533. The docking points of the two groups of piston chambers 534 are connected to the bottom of the upper chamber 531. Inertia piston bodies 535 are arranged in the two groups of oil introduction chambers 533. The inertia piston bodies 535 slide in cooperation with the piston chambers 534.
[0041] Furthermore, the inertia piston body 535 is a spherical structure, the piston cavity 534 is a circular pipe structure, and the diameter of the piston cavity 534 is the same as the diameter of the inertia piston body 535. The two groups of piston cavities 534 are both inclined upward, thereby forming a concave structure in the area between the two groups of piston cavities 534. When the slide 2 is stationary, under the action of gravity, the inertia piston body 535 automatically moves to the concave structure in the middle of the two groups of piston cavities 534. At this time, the upper cavity 531 is connected to the piston cavity 534. When the equipment is powered on and the mover 21 drives the slide 2 to move, whether it is in the acceleration state or the deceleration state, or the starting state and the braking state, the inertia piston body 535 will slide into the piston cavity 534 on the corresponding side due to inertia. At this time, refer to the attached manual Fig.11 The inertial piston body 535 forms a piston structure, which squeezes the lubricating oil in the original oil inlet chamber 533 and the piston chamber 534 upward, thereby improving the effect of the lubricating oil seeping out from the upper oil brush structure 52, thereby improving the lubrication effect between the upper guide rod 3 and the roller 41, and further reducing the wear between the guide rod 3 and the roller 41.
[0042] Refer to the instruction manual Fig.11 In this embodiment, a reflux groove 54 is further provided at the top of the inner extension structure 51, that is, a reflux groove 54 is provided between the two groups of oil brushing structures 52 at the top of the inner extension structure 51, and the reflux groove 54 is connected with the upper cavity 531. On the one hand, the upper space of the upper cavity 531 can be kept connected with the outside atmosphere, so that when the inertial piston body 535 is reset to the middle concave structure, the lubricating oil in the upper cavity 531 can automatically flow to the corresponding piston cavity 534 for replenishment. On the other hand, if a large amount of lubricating oil seeps out of the oil brushing structure 52, the excess lubricating oil can flow back from the reflux groove 54 to the upper cavity 531 to reduce waste.
[0043] Refer to the instruction manual Figure 6 and Figure 8The present embodiment further provides a braking system. Specifically, a braking structure 6 is provided on one side of the inner extension structure 51 corresponding to the side wall of the guide groove 12. The braking structure 6 is slidably installed in the inner extension structure 51. An electromagnetic coil 62 is provided in the inner extension structure 51. A magnet 61 is provided on one side of the braking structure 6 corresponding to the electromagnetic coil 62. A tension elastic member is provided between the braking structure 6 and the inner extension structure 51. The tension elastic member is used to provide a pulling force to the brake structure 6 in the inner direction of the inner extension structure 51. Therefore, in actual use, the braking structure 6 does not contact the inner wall of the guide groove 12. When braking is required, the electromagnetic coil 62 is energized to form a magnetic field opposite to that of the magnet 61, so that the braking structure 6 is pushed outward to squeeze the side wall of the guide groove 12 to achieve braking.
[0044] It should be noted that, compared with directly setting the brake on the guide rod 3 and the brake on the guide rail structure in the prior art, the braking method provided in this embodiment can set the brake contact surface on the outer wall of the guide base 1, that is, the actual brake wear is between the brake structure 6 and the guide base 1. This method will not cause wear on the guide rod 3 and the key guide structure, can ensure the guiding accuracy of the guide rod 3, and further improve the service life of the linear motor module. In addition, an auxiliary brake structure, such as a brake strip, can be embedded and installed in the side wall of the guide groove 12 to improve the braking effect and reduce damage to the guide base 1.
[0045] Based on the above-mentioned implementation mode, in the usage scenario with high intensity of movement, fast movement speed and many braking times, the movement time of roller 41 is long, and the internal energy converted into mechanical kinetic energy is large, which may easily lead to the increase of temperature around guide rod 3 and roller 41. In particular, the temperature increase of brake structure 6 caused by braking may easily cause slight expansion of guide rod 3 or roller 41. Due to the precision requirement, the fit between roller 41 and guide rod 3 is originally a high-precision fit. When guide rod 3 or roller 41 produces thermal expansion, it may easily increase the pressure between roller 41 and guide rod 3, thereby increasing wear. For this reason, the present embodiment also provides the following technical solution. Specifically, the shapes of inner extension structure 51 and guide groove 12 are adapted to each other, and a gap is provided between inner extension structure 51 and guide groove 12. Gap, that is, two groups of inwardly extending structures 51 and the guide plate 4 cooperate with the guide groove 12 to form a relative protective space, and the roller 41 is located in the protective space, and an air inlet pipe 44 is arranged on the guide plate 4, and an air blowing system is arranged on the air inlet pipe 44, and the air blowing system is used to inject air into the inner space of the guide plate 4, and make the air flow out from the gap between the inwardly extending structure 51 and the guide groove 12, so as to realize the air exchange in the inner space of the roller 41, and then realize the heat dissipation of the roller 41 and the guide rod 3. At the same time, there is airflow flowing out of the gap between the inwardly extending structure 51 and the guide groove 12, and external dust and other debris will not enter the inner space of the roller 41, and will not adhere to the adapter groove 42 to affect the matching effect, thereby further improving the safety of the use of the linear motor module.
[0046] Among them, the above-mentioned blowing system can use an air pump to directly inject air into the air inlet pipe 44, and the air can be cooled by using a cooling device, that is, injecting low-temperature air. However, this solution requires an air pipe to be equipped on the guide plate 4 to move with the guide plate 4, which is easy to affect the use of the equipment. It is suitable for occasions with high processing requirements. For ordinary processing scenarios, the following technical solutions can be adopted. For details, refer to the attached manual. Fig.12 An impeller structure 7 is rotatably arranged in the guide plate 4, a rotating shaft 71 is rotatably installed in the guide plate 4, the impeller structure 7 is installed on the rotating shaft 71, the rotating shaft 71 extends into the guide groove 12, a driven wheel 72 is fixedly installed on the rotating shaft 71, the driven wheel 72 rolls with the inner wall of the guide groove 12, and then when the guide plate 4 moves, it can drive the impeller structure 7 to rotate, forming an airflow injected into the air intake pipe 44, and completing the above-mentioned air exchange effect. At the same time, in order to prevent dust from entering, a dust cover 73 is fixedly installed on the outside of the air intake pipe 44.
[0047] Furthermore, since the slide 2 needs to reciprocate, it is easy to cause the impeller structure 7 to rotate in the opposite direction to form a reverse airflow. For this reason, the air inlet pipe 44, the impeller structure 7 and the rotating shaft 71 are provided in at least two groups, wherein the driven wheel 72 on one group of rotating shafts 71 cooperates with the bottom wall of the guide groove 12, and the driven wheel 72 on the other group of rotating shafts 71 cooperates with the top wall of the guide groove 12, and a one-way bearing (i.e., a transmission structure with only one transmission direction, such as a ratchet structure of a bicycle rear wheel) is provided between the rotating shaft 71 and the impeller structure 7, and the transmission directions of the one-way bearings between the two groups of impeller structures 7 and the rotating shaft 71 are opposite. For example, when the slide 2 moves to the left with the guide plate 4, the driven wheel 72 on the left side is When the guide plate 4 moves to the right, the one-way bearing on the left side works to transmit the impeller structure 7, driving the impeller structure 7 on the left side to rotate forward, while the impeller structure 7 on the right side does not rotate because the one-way bearing does not work. On the contrary, when the slide 2 moves to the right with the guide plate 4, the driven wheel 72 on the right side rotates forward, and the one-way bearing on the right side works to transmit the impeller structure 7, driving the impeller structure 7 on the right side to rotate forward, while the impeller structure 7 on the left side does not rotate because the one-way bearing does not work. That is, no matter which direction the guide plate 4 moves, an impeller structure 7 rotates forward to inject air into the inside of the roller 41. At the same time, a one-way valve can be set in the air intake pipe 44 to prevent the air flow from flowing out of the air intake pipe 44 in the reverse direction.
[0048] In addition, only one set of rotating shafts 71 may be provided, on which at least two sets of impeller structures 7 with blades having opposite rotation directions are provided, and the two sets of impeller structures 7 are respectively connected to the rotating shafts 71 via one-way bearings, so that no matter how the rotating shafts 71 rotate, one set of impeller structures 7 can be driven to rotate to form an airflow toward the inside of the roller 41.
[0049] For further information, please refer to the attached manual.
