Description

Technical Field

[0001] The invention relates to the technical field of electromechanical equipment, and in particular to an aluminum-based compact linear motor slide. Background Art

[0002] The existing aluminum-based embedded linear motor slides still have major deficiencies in terms of load-bearing performance, sealing performance and high-speed performance, which affects the application of such slides in working environments such as large lithium battery loads, high panel cleanliness, and higher slide speeds.

[0003] The Chinese patent disclosed "A linear motor slide" with application number 202310389568.6, including a main body mechanism, a lubrication mechanism is installed on the main body mechanism, an opening and closing mechanism for controlling the switch of the lubrication mechanism is provided on the main body mechanism, a dustproof protection mechanism is provided on the main body mechanism, an auxiliary mechanism is installed on the main body mechanism, and a magnetic block cooperating with the auxiliary mechanism is installed on the main body mechanism; a lubrication mechanism is provided on the main body mechanism to adjust the movement stroke of the mover to ensure that the fixed tube can enter the interior of the sliding hole when the mover moves, when the limit rod inside the fixed tube is resisted by the push rod, the sealing plug opens the oil outlet, at this time, the lubricating oil in the oil pot flows from the oil outlet to the inside of the fixed tube, as the push rod repeatedly squeezes the limit rod, the lubricating oil flows from the fixed tube to the inside of the lubrication port inside the mover, and as the mover moves, the lubricating oil is applied to the guide rail to achieve lubrication of the guide rail without removing the protective mechanism on the slide rail.

[0004] However, the existing aluminum-based linear motor slides do not have relevant targeted lubrication designs to cope with high-speed requirements, and grease lubrication is still commonly used. When the movement speed of the slide in the slide is greater than 2m / s, this causes the existing lubrication design to not match the use of the slide. When the slide uses a slide with a smaller aperture, it is easy to cause the slow oil output, resulting in a reduced lubrication range and incomplete lubrication, thereby reducing the lubrication effect.

[0005] In addition, the existing aluminum-based embedded linear motor slide guide system uses an end-mounted reverser, and there are high-precision deep holes in the slide, which limits the length of the raceway cycle and the number of rolling elements. Even if a slide guide system without a return ball hole is used, the embedded slide raceway has weak structural rigidity and strength due to the through grooves processed near the raceway. Therefore, it is even more unsuitable to arrange multiple rows of slide raceways in the upper and lower directions, otherwise the structural strength and rigidity of this part will be further weakened. The above reasons all lead to the limited load-bearing capacity of the slide under the same size, which in turn limits the application of aluminum-based embedded linear motor slides in large load-bearing fields.

The multi-row external slide rail and raceway can not only improve the load-bearing capacity of the slide, but also improve the grinding efficiency and precision in the slide rail and raceway manufacturing process. Compared with the internal raceway and the single external raceway, this multi-roller external structure can use a larger diameter grinding wheel and a more rigid grinding spindle. Furthermore, the external slide rail and raceway not only provides more lateral installation space for the linear electronic drive and stator, but also the external raceway can provide a greater anti-rolling torque under the same rolling body load due to the increased spacing between the left and right sides, thereby increasing the lateral overhang length of the load.

Detailed Embodiment

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0037] Refer to the attached Figures 1-4 , an aluminum-based compact linear motor slide, including a linear motor slide 01, the linear motor slide 01 is composed of a slide rail 02 and a slide base 03. A rotor 06 is installed below the middle of the slide base 03, and a stator 07 is installed above the middle of the slide rail 02. The slide base 03 makes a reciprocating linear motion along the longitudinal direction of the slide rail 02. The slide rail 02 and the slide base 03 are slidably sleeved together through a plurality of raceways 04 and rolling elements 05.

[0038] The raceway 04, the raceway 04 includes a slide rail raceway 402 and a slide base raceway 403. Guide rail grooves 202 are provided on both outer sides of the slide rail 02, and the slide rail raceway 402 is embedded in the guide rail grooves 202. The slide base 03 includes a slide base body 301 and also includes sliders 302 on both sides of the slide base body 301. A plurality of slide base raceways 403 corresponding to the positions of the slide rail raceways 402 are opened on the inner sides of the sliders 302. The slide rail raceways 402 are designed as a plurality of even-numbered columns according to the load-bearing requirements.

[0039] It should be noted that, in this embodiment, it can be designed with 2 columns, 4 columns, 6 columns, etc., and the slide rail raceways 402 are arranged symmetrically left and right, and are arranged vertically on the same side and arranged on the slide rail 02. Moreover, in this embodiment, the slide block raceway 403 and the slider 302 are integrally designed. By heat-treating the whole or part of the slider 302, the hardness of the slide block raceway 403 is increased to the required use level. And, the total number and arrangement of the slide block raceways 403 correspond to those of the slide rail raceways 402. In each group of corresponding slide rail raceways 402 and slide block raceways 403, the slide rail raceways 402 are all located inside. This makes the multi-column external slide rail raceways not only improve the load-bearing capacity of the slide table, but also improve the grinding efficiency and accuracy in the manufacturing process of the slide rail raceways. Compared with the internal raceway and single external raceway, this multi-raceway external structure can use a larger diameter grinding wheel and a grinding spindle with higher rigidity. Further, the external slide rail raceways not only provide more lateral installation space for the linear motor mover and stator, but also, due to the increased distance between the left and right sides of the external raceways, under the same rolling element load, a greater anti-roll moment can be provided, increasing the load lateral overhang length.

[0040] Specifically, a number of U-shaped reverse grooves 321 are opened in the slider 302. A ball unloader 404 is fixedly installed in the reverse groove 321. An unloading channel 405 is opened in the ball unloader 404. The rolling elements 05 circulate in the unloading channel 405 and also circulate between the slide block raceway 403 and the slide rail raceway 402. When the rolling elements 05 are running in any unloading channel 405, it is in the unloading state, called the unloading rolling elements 501. When it runs between any group of corresponding slide block raceway 403 and slide rail raceway 402, it is in the load-bearing state, called the load-bearing rolling elements 502. All the unloading rolling elements 501 and load-bearing rolling elements 502 corresponding to the same reverse groove 321 form a rolling element circulation group 503.

[0041] The slide block body 301 and the slider 302 are fixedly connected into one body with the top screw 303 and the side screw 304 of the slider. Adjusting holes 312 are also designed on both sides of the slide block body 301. The distance between the slide block raceway 403 and the slide rail raceway 402 on the slider 302 can be precisely adjusted by screws.

[0042] The slide rail 02 is also provided with a cavity 101. The mover 06 and the stator 07 are both located in the cavity 101. Guide parts 201 are provided on both sides of the slide rail 02. The raceway 04 and the rolling elements 05 are both located on the outer side of the guide part 201 away from the cavity 101. The ball unloader 404 is clamped and fixed between the slide block body 301 and the slider 302 by a spacer 305. The ball unloader 404 is provided with a dust-proof bottom plate 817 fixed on the slider 302.

[0043] Refer to the appendix Figures 4-14, the present invention also discloses an aluminum-based compact linear motor stage lubrication system. The lubrication system includes a supply mechanism and a recovery mechanism. The supply mechanism consists of a grease supply mechanism 901 and an oil supply mechanism 902. The recovery mechanism includes an oil sump, an inner oil sump 904, and an outer oil sump 905. The oil sump is opened on both sides of the slide rail raceway 402. The inner oil sump 904 and the outer oil sump 905 are located at both ends of the slide rail 02. A movable oil pusher block 700 is installed in the oil sump. The cross-section of the oil pusher block 700 is the same size and shape as the cross-section of the oil sump.

[0044] Specifically, the grease supply mechanism 901 includes a grease outlet 901c located at the slide seat raceway 403, and also includes a grease inlet 901a and a grease passage 901b. The oil supply mechanism 902 includes an oil outlet 902c located in the slide seat raceway 403, and also includes an oil passage 902b and an oil inlet 902a. The aperture of the oil outlet 902c is smaller than the aperture of the grease outlet 901c. The oil passage 902b is located between the oil inlet 902a and the oil outlet 902c. The oil inlet 902a is located on both sides of the slide seat body 301. The oil outlet 902c is located in the slide seat raceway 403 of the slider 302.

[0045] In addition, side grooves 203 are opened on both sides of the guiding portion 201. The side grooves 203 on both sides form an oil sump. The side groove 203 includes an outer side surface 203c, a bottom 203b, and an opening 203a. The angle formed by the outer side surface 203c and the bottom 203b is an acute angle. The outer oil sump 905 is located between the second rib plates 823b on both sides of the end cover 823. The middle of the end cover 823 is the first rib plate 823a. The oil sump and the inner oil sump 904 are connected through an oil collecting port 906.

[0046] In this embodiment, the excess lubricating oil or grease in the raceway 04 will flow downward due to gravity or the reciprocating movement of the slide seat 03 or be accumulated at both ends of the slide rail raceway 402. Through the side grooves 203 designed on the upper and lower sides of the guide rail groove 202 of the guiding portion 201 of the slide rail 02, the angles formed by the outer side surface 203c of the side groove 203 and the plane where the bottom 203b is located are all acute angles. Thus, the grease flowing downward will reach the opening 203a and then be collected on the bottom 203b or in the adjacent acute angle through the outer side surface 203c. All the side grooves 203 that have the function of collecting the grease flowing downward are the oil sump. Further, oil collecting ports 906, inner oil sumps 904, and outer oil sumps 905 are designed at both ends of the slide rail 02. The grease collected in the side grooves 203 and the grease accumulated at both ends due to the reciprocating movement of the slide seat 03 will enter the inner oil sump 904 or the outer oil sump 905 through the oil collecting port 906.

[0047] Under the working condition of oil lubrication, the lubrication system of the present invention can make the lubricating oil spray onto the slide rail raceway in a splash or mist form from the oil outlet of the slide block with a smaller aperture by combining with the appropriate oil pressure in the pipeline set by the external lubricating oil supply system, and spray it along the entire stroke length with the movement of the slide block. The rolling elements establish an oil film during the contact with the slide rail raceway and carry the lubricating oil to the slide block raceway, ball discharger, etc., realizing the lubrication of the entire guiding system.

[0048] Specifically, the oil pushing block 700 includes an oil retaining plate 701. A bottom plate 703 is installed at the bottom of the oil retaining plate 701. A movable moving plate 702 is arranged in the oil pushing block 700. An oil storage chamber 704 is formed among the moving plate 702, the oil retaining plate 701 and the bottom plate 703.

[0049] A moving cavity 706 is formed in the oil pushing block 700. The moving plate 702 is installed in the moving cavity 706. Auxiliary grooves 707 are formed on both sides of the moving cavity 706. Grooves 705 are formed on both sides of the moving plate 702. A plurality of auxiliary balls 708 are arranged between the grooves 705 and the auxiliary grooves 707.

[0050] When the grease flowing downward reaches the opening 203a, it converges at the bottom 203b or the adjacent acute angle through the outer side 203c. When receiving the oil collecting groove, at this time, the oil pushing block 700 will move with the reciprocating movement of the slide block 03, so that the oil pushing block 700 can push the unremoved grease adsorbed in the oil collecting groove to move, achieving the effect of scraping the grease, thereby improving the removal effect. And when the oil pushing block 700 moves, the moving plate 702 will come out of the groove 705 due to inertia, so that the bottom plate 703 abuts against the oil retaining plate 701, forming the oil storage chamber 704. In this way, when the oil pushing block 700 moves, a large amount of grease will be scraped out, and the grease will splash under force, forming secondary pollution. The oil retaining plate 701 can block the splashing grease, and the oil storage chamber 704 can store the grease. Specifically, when the grease splashes under force, its splashing route is parabolic, so that part of it can be blocked by the oil retaining plate 701 and part of it can fall into the oil storage chamber 704. When the oil pushing block 700 moves in the reverse direction, the moving plate 702 will enter the oil pushing block 700 again due to inertia, and the oil storage chamber 704 will open and the grease will fall. But at this time, the grease adsorbed in 903 becomes less, so that the falling grease can be smoothly discharged. And in order to reduce the moving resistance of the moving plate 702, when the oil pushing block 700 moves, the grease can enter the oil pushing block 700 through the groove 705, so that the groove 705, the moving cavity 706 and the auxiliary balls 708 are filled with grease to play a lubricating effect, ensuring the normal movement of the moving plate 702 under inertia.

[0051] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
