Description

Technical Field

[0001] This utility model relates to the field of linear module technology, and in particular to a guide structure for a left-right rotating KK module. Background Technology

[0002] The left-right rotary KK module, as a high-precision linear motion mechanism, integrates left-right rotary threads (with opposite helical directions at both ends) through a special design of a single ball screw, achieving synchronous symmetrical motion of two sliders. This structure can complete the opposing / reverse movement of the sliders within a compact space. However, the ball screw can only provide axial drive force conversion and lacks constraints on the torsional, yaw, and pitch degrees of freedom of the slide table, which may lead to motion instability under asymmetrical loads or rapid acceleration and deceleration conditions.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example

[0023] Reference Figures 1 to 3 This embodiment of the present invention provides a guide structure for a left-right rotating KK module, including a drive member 100 and a slide body 200 extending into the output end of the drive member 100. The slide body 200 includes an opening 201 through the side wall, and an upper half 202 and a lower half 203 separated by the opening 201. The output end of the drive member 100 is connected to a translation member 300. A slide table 400 connected to the translation member 300 is inserted into the opening 201. The upper end of the slide table 400 is provided with a protrusion 401 for clamping the upper half 202, and the lower end is provided with a guide part 402 that slides on the lower half 203. The translation member 300 is provided with abutment parts 301 on both sides that abut against the lower half 203. By clamping the upper half 202 with the protrusion 401 on the slide 400 and the lower half 203 with the contact part 301, the smoothness of the slide 400 moving on the translation member 300 is restricted. Even if the slide 400 moves along the output shaft of the drive member 100, the wear of the balls inside the translation member 300 can be reduced due to the clamping of the upper half 202 with the protrusion 401 and the contact of the lower half 203 with the contact part 301.

[0024] The lower end face of the upper part 202 is provided with a first recess 202-1 extending upward to the upper end face, and the protrusion 401 is connected to the first recess 202-1. The opening of the first recess 202-1 allows the protrusion 401 to be positioned in the first recess 202-1 to limit the protrusion 401, so as to prevent the protrusion 401 from moving freely within the opening 201 when the slide table 400 is accidentally separated from the translation member 300.

[0025] The protrusion 401 includes a first protrusion 401-1 and a second protrusion 401-2 protruding from the upper end face of the slide table 400. The upper end of the first protrusion 401-1 abuts against the lower end face of the first recess 202-1. The opposite sidewalls of the first protrusion 401-1 and the second protrusion 401-2 respectively contact the outer sidewall of the protrusion 401 and the inner sidewall of the first recess 202-1. The clamping of the upper half 202 by the opposite faces of the first protrusion 401-1 and the second protrusion 401-2 ensures the stability of the slide table 400 during operation without the addition of a guide rail, thereby avoiding vibration, crawling, abnormal noise, or positioning deviation caused by unstable operation.

[0026] The lower half 203 has a slide rail 203-1 on one side. The guide part 402 includes a support plate 402-1 on the outer surface of the slide rail 203-1. A screw 402-2 extending into the slide rail 203-1 is threaded onto the support plate 402-1. A detection part 402-3 is provided on the support plate 402-1. The slide rail 203-1 and the support plate 402-1 sliding on the slide rail 203-1 are mainly used to install limit sensors and other equipment, i.e., the detection part 402-3, to ensure that the two slide tables 400 will not move excessively and cause equipment damage.

[0027] The upper surface of the lower half 203 is outwardly curved, and the contact part 301 is also outwardly curved. The curved shape can further increase the fit between the contact part 301 and the lower half 203, and the gap between the inner side of the contact part 301 and the outer side wall of the translation member 300 is triangular. The triangle shape has stability, which further enhances the stability of the translation member 300 when it moves.

[0028] The upper surface of the lower half 203 is provided with a concave arc-shaped groove 203-2, and the contact part 301 is inserted into the arc-shaped groove 203-2. When the contact part 301 is inserted into the arc-shaped groove 203-2, since both the arc-shaped groove 203-2 and the contact part 301 are arc-shaped and fit each other, the contact part 301 can also play a guiding role. At this time, the upper part of the translation component 300 in this left and right rotating KK module has a limiting guide, and the lower part also has a limiting guide, which can further enhance the stability of the translation component 300 during operation.

[0029] The upper surface of the contact part 301 is provided with a semi-circular groove 301-1, which is located at the inlet end of the arc-shaped groove 203-2, and part of the semi-circular groove 301-1 is exposed to the outside. The opening of the semi-circular groove 301-1 allows the inlet end of the arc-shaped groove 203-2 to be further extended and cover part of the semi-circular groove 301-1, thereby further strengthening the connection between the contact part 301 and the arc-shaped groove 203-2, and thus enhancing the smoothness of the translation member 300 during movement.
