Description

Technical Field

[0001] This utility model relates to the field of linear motor equipment, and in particular to slide rails for linear motors. Background Technology

[0002] As an important component of linear motor modules, linear motor guide rails play a crucial role in various fields such as industrial automation, 3D printing, and robotics. Traditional linear motion devices often suffer from problems such as complex structure, cumbersome installation, and low positioning accuracy, which limit their application in high-precision and high-efficiency work scenarios.

[0003] A search revealed Chinese Patent Publication No. CN210350966U, which discloses a slide rail mounting structure for a linear voice coil motor. The structure includes a stator, a mover, and a slide rail. The stator has an internal mounting groove into which the mover is slidably inserted. The outer wall of the mover has a first groove, and the portion of the mounting groove corresponding to the first groove is recessed inward to form a second groove. The openings of the first and second grooves are arranged opposite each other to form a fixed groove, into which the slide rail is slidably inserted. This utility model's slide rail structure primarily involves machining two semi-circular grooves at each end of the metal housing and at each end of the mover. The slide rail is directly inserted into the grooves, and the mover is then installed to achieve the motor's sliding requirements. It is also easy to replace. The slide rail material can withstand repeated friction with the aluminum frame without producing a black, viscous substance. This solves the problem of jamming during repeated movement of the linear voice coil motor and allows for quick replacement, achieving excellent maintainability and enabling long-term motor operation.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 3This utility model provides an embodiment of a linear motor slide rail, including a mounting rail 1 that supports the equipment. A sliding seat 2 is fixedly mounted on the upper surface of the mounting rail 1, which supports the motor seat 3. The use of the mounting rail 1 enables the movement of the equipment. The motor seat 3 is fixedly mounted on the upper surface of the sliding seat 2, and a ball bearing 4 is rolled at the center of the lower surface of the sliding seat 2. During the movement of the sliding seat 2, the ball bearing 4 changes the sliding friction of the bottom surface of the sliding seat 2 from sliding friction to rolling friction, reducing the resistance to the movement of the equipment and improving the movement effect of the equipment. A rail groove 5 is opened at the center of the upper surface of the mounting rail 1, and two sets of auxiliary plates 9 are fixedly connected to both the left and right ends of the upper surface of the mounting rail 1.

[0025] Reference Figure 1 - Figure 3 When the equipment moves at high speed, the compensation component 10 is activated. The compensation component 10 is installed in the groove on the lower surface of the sliding seat 2. The compensation component 10 includes a mounting plate 102, which is elastically connected to the groove on the lower surface of the sliding seat 2 via an elastic rod 101. When the sliding seat 2 tilts to the side, the elastic rod 101 retracts, causing the mounting plate 102 to move upward. Support rods 103 are hinged to both ends of the lower surface of the mounting plate 102. The upward movement of the mounting plate 102 causes the support rods 103 to move. A crossbar 104 is hinged in the groove of the support rod 103. An elastic element 105 is fixedly installed between the two sets of crossbars 104. Under the action of the elastic element 105, the support rods 103 are clamped. The left end of the elastic element 105 is fixedly connected to the left crossbar. On the right surface of 104, the right end of the elastic element 105 is fixedly connected to the left surface of the right crossbar 104, driving the compensation plate 106 to perform a clamping action, so that the compensation plate 106 clamps the outer surface of the auxiliary plate 9. The bottom end of the support rod 103 is fixedly connected to the compensation plate 106. The right surface of the compensation plate 106 is rolledly connected to the moving roller 107. With the rotation of the moving roller 107, the torsional compensation action is performed on the side tilt of the sliding seat 2. The left surface of the compensation plate 106 is fixedly connected to multiple sets of evenly distributed magnetic strips 108 to prevent the sliding seat 2 from moving at high speed in the mounting rail 1 and causing the equipment to derail. The magnetic strips 108 have the same magnetism as the magnetic plate 12, which improves the protection of the equipment during use and enhances the stability of the equipment during long-term operation.

[0026] Reference Figure 1 - Figure 3The front surface of the mounting rail 1 is provided with auxiliary components, including mounting posts 6. The mounting posts 6 are fixedly connected to the front surface of the mounting rail 1. When the equipment needs to be assembled, the mounting posts 6 are used in conjunction with the mounting holes 8 to achieve the assembly process. The rear surface of the mounting rail 1 has two sets of mounting holes 8. The cross-sectional area of ​​the outer surface of the mounting posts 6 is matched with the cross-sectional area of ​​the groove in the mounting holes 8. The mounting posts 6 are snapped into the inner wall of the mounting holes 8, which improves the adaptability of the equipment. Furthermore, through the magnetic force of the magnetic plate 12 and the magnetic strip 108, magnetic plates 12 are fixedly connected to the left and right sides of the inner wall of the groove on the lower surface of the sliding seat 2 near the compensation plate 106. This prevents the support rod 103 from breaking due to excessive deflection angle, improves the protection of the support rod 103, and enhances the service life of the equipment. The upper end of the magnetic plate 12 is detachably connected to a sound-absorbing strip 11. The sound-absorbing strip 11 prevents the equipment from generating a lot of noise under high-speed movement, improves the noise reduction effect of the equipment, and enriches the functionality of the equipment.

[0027] Working principle: When the equipment moves at high speed, the compensation component 10 is activated. When the sliding seat 2 tilts, the elastic rod 101 retracts, causing the mounting plate 102 to move upward. The upward movement of the mounting plate 102 drives the support rod 103 to move. Under the action of the elastic element 105, the support rod 103 is clamped, which in turn causes the compensation plate 106 to clamp, thus clamping the outer surface of the auxiliary plate 9. Combined with the rotation of the moving roller 107, this provides torque compensation for the tilting of the sliding seat 2, preventing the sliding seat 2 from derailing due to high-speed movement in the mounting rail 1. This improves the protection of the equipment during use and enhances the stability of the equipment during long-term operation.

[0028] When the equipment needs to be combined, the mounting column 6 and mounting hole 8 are used to assemble the equipment, which improves the adaptability of the equipment. Furthermore, the magnetic force of the magnetic plate 12 and magnetic strip 108 prevents the support rod 103 from breaking due to excessive deflection angle, thus improving the protection of the support rod 103 and extending the service life of the equipment. The sound-absorbing strip 11 prevents the equipment from generating a lot of noise when moving at high speed, improving the noise reduction effect of the equipment and enriching its functionality.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
