Description

Technical Field

[0001] This utility model relates to the field of mobile device technology, and in particular to a highly stable sliding table translation mechanism. Background Technology

[0002] Slide tables are used in some motion mechanisms. These tables typically move horizontally relative to a support under the action of a horizontal drive mechanism. Sometimes, the slide table needs to extend to the side of the support, causing a shift in the center of gravity and slide table vibration. This creates a torque perpendicular to the axial direction on the horizontal drive mechanism, potentially damaging it.

[0003] Chinese patent CN216444965U discloses a translation drive device, which includes a base with a pair of parallel guide rails. A sliding seat is slidably mounted on the guide rails, and a translation drive frame is mounted on the sliding seat via a lifting mechanism. A translation power device is mounted on the translation drive frame. Here, a roller is located on each of the left and right sides below the sliding seat in the sliding direction. The two rollers are coaxial and respectively cooperate with the two guide rails. Therefore, the sliding seat is equivalent to the chassis of a train, and the rollers are equivalent to the wheels running on the rails. Its main function is to balance the center of gravity between the two rollers, and it does not significantly contribute to the wear prevention of the translation power device. Moreover, in some applications, this double-guide-rail base occupies too much space and is unnecessary.

[0004] Therefore, there is a need for a slide translation mechanism with a simple structure that reduces wear on the drive components. Utility Model Content

[0005] The main purpose of this utility model is to provide a highly stable sliding table translation mechanism that can reduce the wear of horizontal drive components through a small space-consuming and simple structure.

[0006] This utility model achieves the above objective through the following technical solution: a highly stable sliding table translation mechanism, comprising:

[0007] The fixed frame extends along the X-direction;

[0008] A slide rail is provided on the X-direction side of the fixed frame and its length direction is along the X-direction;

[0009] A slide table is located above the fixed frame and connected downward to a support foot at the X-axis end. The bottom of the support foot is rotatably equipped with a roller that can slide along the slide rail. The axis of the roller is along the Y-axis, and both the X-axis and the Y-axis are located in the horizontal plane and are perpendicular to each other.

[0010] A horizontal drive unit is connected to the fixed frame and drives the slide to slide between the slide rail and the fixed frame.

[0011] Specifically, the upper part of the slide table is provided with a workpiece positioning frame and two baffles, with the two baffles located on both sides of the workpiece positioning frame in the X direction.

[0012] Specifically, the horizontal drive component is a cylinder, which has a cylinder shaft with its axis along the X direction, and the end of the cylinder shaft is connected to one end of the slide near the support foot.

[0013] Specifically, the upper part of the slide rail has an upward-opening U-shaped groove, the length direction of the U-shaped groove is along the X direction, the bottom of the U-shaped groove is connected to the ground by two or more pads, and a height adjustment screw is connected between the U-shaped groove and the pads.

[0014] Specifically, the upper part of the fixing frame is provided with several X-axis sliders, and the lower part of the slide table is provided with an X-axis slide rail that matches the X-axis sliders. The X-axis length of the X-axis slide rail is longer than the X-axis length of the slide table.

[0015] The beneficial effects of this utility model's technical solution are:

[0016] This invention uses a slide table to press the originally suspended end against the slide rail by the support foot and roller. The slide rail can ensure that the height does not change when the roller moves, so the slide table can move smoothly along the X direction. This makes the horizontal drive component less prone to wear and reduces its service life. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to specific embodiments.

[0027] Example:

[0028] like Figure 1 and Figure 2 As shown, a highly stable sliding table translation mechanism 100 of this utility model includes a fixed frame 1, a slide rail 2, a sliding table 3, and a horizontal drive member 4. The length direction of the fixed frame 1 is along the X direction. The slide rail 2 is located on the X-direction side of the fixed frame 1, and its length direction is along the X direction. The sliding table 3 is located above the fixed frame 1 and has a support foot 31 connected downward at its X-direction end. The bottom of the support foot 31 is rotatably equipped with a roller 32 that can slide along the slide rail 2. The axis of the roller 32 is along the Y direction. Both the X and Y directions are located in the horizontal plane and are perpendicular to each other. The horizontal drive member 4 is connected to the fixed frame 1 and drives the sliding table 3 to slide between the top of the slide rail 2 and the top of the fixed frame 1.

[0029] The horizontal drive component 4 can be a cylinder, screw drive mechanism, etc., with its axis along the Y direction. The position of the fixed frame 1 itself is fixed. When the slide table 3 slides along the X direction, most of its part will gradually move outside the upper projection range of the fixed frame 1, and the center of gravity will not remain above the fixed frame 1. At this time, the originally suspended end of the slide table 3 will be pressed against the slide rail 2 by the support foot 31 and the roller 32. The slide rail 2 can ensure that the height of the roller 32 does not change when it moves, so the slide table 3 can move smoothly along the X direction. In this way, the horizontal drive component 4 is not easy to wear and its service life is reduced.

[0030] like Figure 1 and Figure 2 As shown, the upper part of the slide table 3 is provided with a workpiece positioning frame 33 and two baffles 34, with the two baffles 34 located on both sides of the workpiece positioning frame 33 in the X direction.

[0031] The workpiece positioning frame 33 is used to fix the workpiece 200, while the baffles 34 on both sides play a protective role to prevent the workpiece 200 from being damaged or knocked off during movement.

[0032] like Figure 1 and Figure 2 As shown, the horizontal drive component 4 is a cylinder, which has a cylinder shaft 41 with its axis along the X direction. The end of the cylinder shaft 41 is connected to one end of the slide table 3 near the support foot 31.

[0033] The X-axis length occupied by the cylinder body is basically the same as the X-axis length of the fixed frame 1, and the cylinder shaft 41 can extend a distance slightly less than the length of the cylinder body, thereby making the slide table 3 have a larger sliding distance.

[0034] like Figure 1As shown, the upper part of the slide rail 2 has an upward-opening U-shaped groove 21. The length direction of the U-shaped groove 21 is along the X direction. The bottom of the U-shaped groove 21 is connected to the ground by two or more pads 22. A height adjustment screw (not exposed) is connected between the U-shaped groove 21 and the pads 22.

[0035] The U-shaped groove 21 can limit the movement of the roller 32 on both sides. Theoretically, the bottom of the U-shaped groove 21 should be level to meet the requirements of reducing wear. However, during installation, the fixing method will affect the levelness of the U-shaped groove 21. During operation, the deformation of the U-shaped groove 21 under pressure may also cause changes in levelness. Therefore, it is necessary to control the height of each fixed position of the U-shaped groove 21 through the height adjustment screw, shorten the overhang length of the U-shaped groove 21, and ensure the smooth sliding of the slide table 3.

[0036] like Figure 1 and Figure 2 As shown, the upper part of the fixed frame 1 is provided with several X-axis sliders 11, and the lower part of the slide table 3 is provided with an X-axis slide rail 35 that matches the X-axis sliders 11. The X-axis length of the X-axis slide rail 35 is longer than the X-axis length of the slide table 3.

[0037] The X-axis slide rail 35, in conjunction with the X-axis slider 11, allows the slide table 3 to move strictly along the X-axis and provides minimal sliding resistance. The X-axis slider 11 is positioned on the fixed frame 1 near the slide rail 2, and the X-axis slide rail 35 can be appropriately lengthened to allow the slide table 3 to slide a longer distance.

[0038] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
