Description

Technical Field

[0001] The utility model belongs to the technical field of displacement adjustment equipment, in particular to a linear slide. Background Art

[0002] The linear slide is a key component widely used in the fields of automation and precision machinery. It can achieve precise linear motion and is used for transporting workpieces, positioning parts, performing assembly operations, feeding tools, clamping workpieces, etc.

[0003] In related technologies, linear slides are driven by either pneumatic or hydraulic cylinders. Compressed air entering the cylinder creates a pressure differential within the cylinder, or hydraulic oil entering the hydraulic cylinder creates a pressure differential within the cylinder, pushing the piston to initiate movement. The piston is typically connected to a piston rod, and the movement of the piston drives the piston rod along with it. The piston rod is connected to the slide, and as the piston moves, the slide gradually moves to the desired operating position.

[0004] However, if larger loads or longer strokes are required, the size of the pneumatic or hydraulic cylinder will increase, which in turn occupies more installation space. Furthermore, to ensure proper operation, the pneumatic cylinder requires auxiliary equipment such as air source processing devices and piping, which also increases the equipment's space requirements. Hydraulic systems require equipment such as hydraulic pumps, oil tanks, valve blocks, and piping, all of which are large and require significant space. This can particularly restrict the installation and use of hydraulic cylinder slides in applications where space is limited. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, this embodiment provides a linear slide, including a base 1, a transmission component 2 and a moving component 3.

[0027] A mounting plate 4 is provided on the base 1; the mounting plate 4 is fixedly connected to the transmission assembly 2. The base 1 is fixedly connected to the transmission assembly 2 via the mounting plate 4. Optionally, the mounting plate 4 is detachably connected to the base 1 and the transmission assembly 2.

[0028] like Figure 2 As shown, the transmission assembly 2 includes a motor 21 and a lead screw 22. The housing of the motor 21 is detachably connected to the mounting plate 4. The output shaft of the motor 21 is detachably connected to the lead screw 22. The axis of the lead screw 22 is collinear with the axis of the output shaft of the motor 21. In this embodiment, the connection between the output shaft of the motor 21 and the lead screw 22 eliminates the need for a bearing seat and coupling, reducing the overall size of the slide and conserving installation space.

[0029] like Figure 3 As shown, the moving assembly 3 includes a slide 31 and a bearing plate 32; the slide 31 is slidably connected to the base 1 along the axial direction of the screw 22; the screw 22 passes through the slide 31 along the axial direction of the screw 22 and is screwed to the slide 31; the bearing plate 32 is arranged on the top of the slide 31, and optionally, the bearing plate 32 is detachably connected to the slide 31. The output shaft of the motor 21 drives the screw 22 to rotate, that is, the screw 22 rotates circumferentially, and the rotational motion of the screw 22 is converted into linear motion of the slide 31, so that the slide 31 moves along the axial direction of the screw 22. After determining the forward and reverse directions of the output shaft of the motor 21, the forward and reverse rotation of the output shaft of the motor 21 realizes the reciprocating motion of the slide 31 along the axial direction of the screw 22.

[0030] For example, the interior of the slide 31 is provided with a nut 33 that matches the external threads of the lead screw 22; the nut 33 is fixedly connected to the slide 31 via bolts. If the lead screw 22 were directly threaded to the slide 31, wear would necessitate a replacement of the slide 31. The provision of the nut 33 effectively isolates the threaded connection between the slide 31 and the lead screw 22. That is, the lead screw 22 is threadedly connected to the nut 33 through a detachable connection with the slide 31. When wear occurs at the threaded connection, the nut 33 can be replaced with a new one, reducing the maintenance cost of the slide.

[0031] For example, Figure 4 As shown, the base 1 is provided with a cavity 11 extending through the base 1 along the axial direction of the lead screw 22; the top of the cavity 11 is provided with an opening; a slide 31 is located within the cavity 11; guide rails 111 are provided on the inner wall of the cavity 11, located on either side of the slide 31; sliders 112 are provided on either side of the slide 31, matching the two guide rails 111; the slide 31 moves along the axial direction of the lead screw 22 on the guide rails 111 via the sliders 112 on either side. The sliders 112 engage the guide rails 111, allowing the slide 31 and the carrier plate 32 to reciprocate along the axial direction of the lead screw 22, guided by the guide rails 111.

[0032] For example, a first groove 1111 is provided on one side of each guide rail 111 close to the slide 31, which passes through the guide rail 111 along the axial direction of the screw 22; a second groove 311 is provided on both sides of the slide 31, which passes through the slide 31 along the axial direction of the screw 22; the slider 112 is located in the through hole formed by the first groove 1111 and the second groove 311. The cross-sections of the first groove 1111 and the second groove 311 perpendicular to the axial direction of the screw 22 are both V-shaped structures; the notches of the first groove 1111 and the second groove 311 are opposite to each other to form a through hole, and the cross-section of the formed through hole in the direction perpendicular to the axial direction of the screw 22 is a square structure; Figure 5 As shown, the slider 112 on each side of the slide 31 includes a plurality of rollers 1121; each roller 1121 has the same height and diameter; the roller 1121 is located in the through hole formed by the first groove 1111 and the second groove 311. Optionally, in the first groove 1111, the axis of any roller 1121 is perpendicular to the axis of at least one roller 1121 among the remaining rollers 1121. The roller 1121 limits the slide 31 in the direction perpendicular to the plane where the slide 31 is located, that is, it prevents the slide 31 from being displaced in the direction perpendicular to the plane where the slide 31 is located. The slide 31 is precisely moved in a straight line along the square through hole through the rollers 1121, and the supporting plate 32 on the slide 31 is used for the customer to install the hole to connect the carrier or product.

[0033] A stop plate 312 is detachably connected to the slide 31 on both sides of the slide 31. The stop plates 312 are provided with a plurality of stop holes 3121 for receiving the rollers 1121. The stop holes 3121 are equidistantly spaced to prevent the rollers 1121 from being too close to or too far apart in the through hole formed by the first and second grooves 1111 and 311, and to prevent the rollers 1121 from falling out of the through hole formed by the first and second grooves 1111 and 311 during movement of the slide 31.

[0034] The linear slide provided in this embodiment further includes a controller 5 , which is electrically connected to the motor 21 to control the rotation direction of the output shaft of the motor 21 , thereby enabling the slide 31 to reciprocate along the axial direction of the lead screw 22 .

[0035] In summary, this embodiment provides a linear slide, including a base 1, a transmission assembly 2 and a moving assembly 3; a mounting plate 4 is provided on the base 1; the mounting plate 4 is fixedly connected to the transmission assembly 2; the transmission assembly 2 includes a motor 21 and a screw 22; the outer casing of the motor 21 is detachably connected to the mounting plate 4; the output shaft of the motor 21 is detachably connected to the screw 22; the axis of the screw 22 is collinear with the axis of the output shaft of the motor 21; the moving assembly 3 includes a slide 31 and a supporting plate 32; the slide 31 is slidably connected to the base 1 along the axial direction of the screw 22; the screw 22 passes through the slide 31 along the axial direction of the screw 22 and is screwed to the slide 31; the supporting plate 32 is arranged on the top of the slide 31. In this embodiment, after the output shaft of the motor 21 drives the screw 22 to rotate, the rotational motion of the screw 22 will be converted into the linear motion of the slide 31, so that the slide 31 moves back and forth along the axial direction of the screw 22, which solves the problem in the related technology that when the slide is driven by a cylinder or a hydraulic cylinder, the cylinder or hydraulic cylinder has a large volume, resulting in a large installation space being occupied.
