Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rails, in particular to a slider for a linear guide rail with height adjustment. Background Art

[0002] Linear guides are used in high-precision or high-speed linear reciprocating motion situations, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions. The slider is a moving block that moves on the linear guide for installing fixed components.

[0003] In the prior art, the slider is a relatively independent device, and the overall shape of the slider is fixed. When the linear guide rail is used, in some special working environments, the horizontal positions of several linear guide rails are different. Therefore, it is necessary to install a slider of matching height that can control the fixed component in a horizontal state. Therefore, a slider of a specific height needs to be used, and its use is relatively limited. At the same time, when removing the fixed component on the slider, it is necessary to remove the bolts installed between the slider and the fixed component inside the device on which the linear guide rail is installed, and then the fixed component can be disassembled, which is a relatively cumbersome operation.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a slider for a linear guide rail with height adjustment includes a slider body 1, a mounting plate 2 is installed on the top of the slider body 1, and limiting holes 3 are symmetrically provided at both ends of the slider body 1. A limiting rod 4 is fixedly installed at the bottom of the mounting plate 2 corresponding to the position of the limiting hole 3, and the limiting hole 3 is slidably connected to the limiting rod 4. Positioning rods 5 are symmetrically installed on both sides of the slider body 1, and fixed blocks 6 are fixedly installed on both sides of the mounting plate 2 corresponding to the position of the positioning rod 5. The bottom end of the fixed block 6 is rotatably installed with an anti-slip block 7 through an axle pin, and a socket 8 is provided at the end of the anti-slip block 7, which is slidably connected to the positioning rod 5.

[0021] like Figures 1 to 4 As shown, a mounting block 9 is fixedly installed at one end of the top of the slider body 1, and a screw 10 is rotatably installed in the middle of the mounting block 9 through a bearing. A fixing rod 11 is symmetrically fixed on one side of the mounting block 9, and an extrusion block 12 is slidably installed between the two fixing rods 11. The screw 10 is threadedly connected to the middle of the extrusion block 12, and an extrusion slope 13 is provided at one corner of the top of the extrusion block 12. A trapezoidal block 14 is fixedly installed in the middle of the mounting plate 2 corresponding to the position of the extrusion block 12, and the extrusion block 12 is in extrusion contact with the trapezoidal block 14.

[0022] By controlling the rotation of the screw 10, the threaded connection between the screw 10 and the extrusion block 12 will drive the extrusion block 12 to move along the fixed rod 11, which will drive the extrusion inclined surface 13 of the extrusion block 12 to extrude the trapezoidal block 14, and will drive the mounting plate 2 to rise, so that the components installed on the mounting plate 2 can be raised.

[0023] like Figures 1 to 4 As shown, a mounting bracket 15 is fixedly mounted on the side of the mounting block 9 away from the fixed rod 11, a worm 16 is rotatably mounted in the middle of the mounting bracket 15, a worm wheel 17 is fixedly mounted at one end of the screw rod 10 corresponding to the position of the worm 16, the worm wheel 17 is meshed with the worm 16, and a knob 18 is fixedly mounted on the bottom end of the worm 16.

[0024] The worm 16 is rotated by rotating the knob 18, and the screw 10 is rotated by the engagement of the worm wheel 17 and the worm 16. The rotation angle of the screw 10 can be controlled to prevent the mounting plate 2 from automatically rising and falling in a natural state.

[0025] like Figures 1 to 4 As shown, connecting blocks 19 are symmetrically fixedly installed on both sides of the slider body 1, and a sliding hole 20 is opened in the middle of the connecting block 19. The sliding hole 20 is slidably connected to the positioning rod 5. An extrusion spring 21 is sleeved on the outer side of the middle part of the positioning rod 5. The top of the extrusion spring 21 is fixedly connected to the lower surface of the sliding hole 20. A ring 22 is slidably installed on the outer side of the positioning rod 5, and the bottom end of the extrusion spring 21 is fixedly connected to the upper surface of the ring 22.

[0026] When the mounting plate 2 rises, the fixing block 6 will be driven to rise synchronously, and the anti-falling block 7 at the bottom of the fixing block 6 will continue to be on the outside of the positioning rod 5, and the anti-falling block 7 will squeeze the ring 22. At this time, the squeezing spring 21 will be in a compressed state, and the reverse action force of the squeezing spring 21 will continue to drive the squeezing spring 21 to squeeze the anti-falling block 7 downward, so as to prevent the mounting plate 2 with the fixing block 6 installed from falling off from the slider body 1.

[0027] like Figures 1 to 4 As shown, a connecting plate 23 is fixedly mounted on the top of the two positioning rods 5 on the same side.

[0028] By canceling the extrusion block 12 to squeeze the trapezoidal block 14, the mounting plate 2 is reset under the downward squeezing of the anti-falling block 7 by the extrusion spring 21, and then by pulling up the connecting plate 23, the positioning rod 5 is driven to slide and rise inside the socket 8 until the positioning rod 5 is separated from the anti-falling block 7. Then, the anti-falling block 7 is rotated to drive the mounting plate 2 to fall off from the positioning rod 5, making it easier to disassemble the mounting plate 2.

[0029] like Figures 1 to 4 As shown, a chamfer 24 is formed at the bottom end of the positioning rod 5 .

[0030] It is convenient to slide the positioning rod 5 into the insertion hole 8 of the anti-slip block 7 when installing the mounting plate 2 on the slider body 1.

[0031] The utility model provides a slider for a linear guide rail with height adjustment, and the specific working principle is as follows:

[0032] When the device is in use, the slider body 1 is installed on the linear guide rail, and the worm 16 is driven to rotate by rotating the knob 18. The engagement of the worm wheel 17 with the worm 16 drives the screw 10 to rotate. The threaded connection between the screw 10 and the extrusion block 12 drives the extrusion block 12 to move along the fixed rod 11, which drives the extrusion inclined surface 13 of the extrusion block 12 to squeeze the trapezoidal block 14, which drives the mounting plate 2 to rise, and the components installed on the mounting plate 2 can be raised;

[0033] When the mounting plate 2 rises, the fixing block 6 will be driven to rise synchronously, and the anti-falling block 7 at the bottom of the fixing block 6 will continue to be on the outside of the positioning rod 5, and the anti-falling block 7 will squeeze the ring 22. At this time, the squeezing spring 21 will be in a compressed state. The reverse force of the squeezing spring 21 will continue to drive the squeezing spring 21 to squeeze the anti-falling block 7 downward, so as to prevent the mounting plate 2 with the fixing block 6 installed from falling off from the slider body 1.

[0034] When disassembling the mounting plate 2, the extrusion block 12 is removed to squeeze the trapezoidal block 14, and the mounting plate 2 is reset under the downward squeezing of the anti-falling block 7 by the extrusion spring 21. Then, by pulling up the connecting plate 23, the positioning rod 5 is driven to slide and rise inside the socket 8 until the positioning rod 5 is disengaged from the anti-falling block 7. Then, the anti-falling block 7 is rotated to drive the mounting plate 2 to fall off from the positioning rod 5, which is used for disassembling the mounting plate 2.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
