Description

Technical Field

[0001] The utility model relates to the field of slide tables and is used in a vertical load high-speed reciprocating motion mechanism. Specifically, it is an anti-torsion linear slide table. Background Technique

[0002] In a vertical load high-speed reciprocating motion mechanism, a cam-linkage mechanism is usually used to realize the conversion from rotational motion to linear motion. However, during the linear motion of the linkage of such a mechanism, there will be slight torsion ( Figure 1 as indicated by the arrow), and after long-term movement, the slide table will be worn. At the same time, the vertical load will also cause the entire mechanism to tilt towards the side with gaps and load ( Figure 2 as indicated by the arrow), and wear will also occur. Therefore, an anti-torsion linear slide table is designed to reduce the wear of the linear slide table and improve the anti-torsion ability at the same time.

[0003] The information disclosed in this background section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0004] The technical problem to be solved by the present utility model is to overcome the above technical defects and provide an anti-torsion linear slide table, which can reduce the wear of the linear slide table and improve the anti-torsion ability at the same time.

[0005] To solve the above problems, the technical solution of the present utility model is: an anti-torsion linear slide table, including a first slide table body and a second slide table body, and the first slide table body slides inside the second slide table body;

[0006] A cage, which is located between the first slide table body and the second slide table body. A plurality of equally spaced limit holes are provided on the surface of the cage, and steel balls are arranged inside the limit holes;

[0007] An anti-corrosion rubber pad, which is arranged on the inner side of the second slide table body. A pressing plate is provided at the other end of the anti-corrosion rubber pad, and the pressing plate is located on one side of the cage and does not contact the cage;

[0008] A first round steel, which is located at both ends on one side of the cage;

[0009] A second round steel, which is located at both ends on the other side of the cage;

[0010] A first cover plate, which is arranged at both ends of the first slide table body;

[0011] A second cover plate, which is arranged at both ends of the second slide table body.

[0012] Further, the cross-section of the second slide body is U-shaped, the two ends inside the second slide body are of "E" type structure, the cross-section of the first slide body is of "king" type structure, four groups of cavities are formed between the first slide body and the second slide body, and the four cages are respectively located inside the four cavities. The length of the cage is less than that of the first slide body and the second slide body.

[0013] Further, threaded holes one are provided at both ends of the first slide body, and screws one for fixing the first cover plate are arranged inside the threaded holes one. Threaded holes two are provided at both ends of the second slide body, and screws two for fixing the second cover plate are arranged inside the threaded holes two.

[0015] The advantages of the present utility model compared with the existing technology are as follows:

[0016] (1) The present utility model uses steel balls and round steel to achieve point-contact sliding, reducing friction. Using the ball and round steel structure, arranged in two rows, while realizing the guiding of the sliding direction, it is equivalent to increasing the stress points against torsion, minimizing the influence brought by torsion to the greatest extent. The anti-corrosion rubber pad is used to achieve extrusion and buffering, reducing the gap, making the fit tight, and can also buffer the external minute torsion force, improving the stability of the overall structure.

[0026] Embodiment 1

[0027] As Figures 3 to 5 shown, a torsion-resistant linear slide table includes a first slide table body 1 and a second slide table body 2. The first slide table body 1 slides inside the second slide table body 2. The cross-section of the second slide table body 2 is U-shaped, and both ends inside the second slide table body 2 are of "E" - shaped structures. The cross-section of the first slide table body 1 is of "king" - shaped structure. Four groups of cavities are formed between the first slide table body 1 and the second slide table body 2. Four cages 3 are respectively located inside the four cavities. The length of the cage 3 is less than that of the first slide table body 1 and the second slide table body 2, and the cage 3 can slide inside the first slide table body 1 and the second slide table body 2.

[0028] A plurality of equally spaced limit holes 4 are opened on the surface of the cage 3. Steel balls 5 are installed inside the limit holes 4. The anti - corrosion rubber pad 6 is located inside the second slide table body 2. The other end of the anti - corrosion rubber pad 6 is installed with a pressing plate 7. The pressing plate 7 is located on one side of the cage 3 and does not contact the cage 3. Round steel 8 is located at both ends on one side of the cage 3 and is inside the second slide table body 2. Round steel 9 is located at both ends on the other side of the cage 3 and is inside the first slide table body 1. The anti - corrosion rubber pad 6 is in a state of deformed extrusion. One end of the pressing plate 7 is mutually extruded with the round steel 8, and both sides of the steel ball 5 are mutually extruded with the round steel 8 and the round steel 9.

[0029] A first cover plate 10 is provided at both ends of the first slide table body 1, and a second cover plate 11 is provided at both ends of the second slide table body 2. Threaded holes 1 are opened at both ends of the first slide table body 1, and screws 12 for fixing the first cover plate 10 are installed inside the threaded holes 1. Threaded holes 2 are opened at both ends of the second slide table body 2, and screws 13 for fixing the second cover plate 11 are installed inside the threaded holes 2. The cage 3, the anti - corrosion rubber pad 6, the pressing plate 7, the round steel 8, and the round steel 9 can be restricted inside the slide table, so that all the components of the slide table form a whole and there will be no dropping of components during use.

[0030] The anti-corrosion rubber pad 6 is in a state of deformation extrusion. The anti-corrosion rubber pad 6 compresses the pressing plate 7 through minute deformation extrusion, enabling the overall structure to be in a stable state, and at the same time being able to buffer minute torsions. The pressing plate 7 is responsible for transmitting force to the anti-corrosion rubber pad 6, and also provides a contact surface with sufficient strength for the first round steel 8 and the second round steel 9. The first round steel 8, the second round steel 9 and the steel balls 5 are arranged in a double row, increasing the force on the four surfaces in the non-movement direction and effectively resisting torsion.

[0031] The above has described the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
