Detailed Implementation

[0021] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0022] Please see Figures 1 to 3 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this utility model, should fall within the scope of the disclosed technical content. Furthermore, the terms "front," "rear," "left," "right," "upper," "lower," "middle," "first," and "second," etc., used in this specification are merely for clarity and are not intended to limit the scope of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this utility model.

[0023] Please see Figures 1-3 This utility model provides a slide mechanism for a dual-worktable bidirectional translational exchange device. The slide mechanism 30 includes a slide body 33, and a pulley assembly 31 is provided at the upper end of the slide body 33. The pulley assembly 31 includes a base plate 311 distributed laterally along the slide body 33. A plurality of pulley seats 312 are mounted on the base plate 311, and a pulley 313 is mounted in each pulley seat 312 through a rotating connector. A first linear actuator 35 is provided on the slide body 33. The first linear actuator 35 includes, but is not limited to, a retractable linear drive device such as a linear cylinder. In this utility model, a linear drive device that is easy to assemble and meets industrial requirements is selected, and no additional restrictions should be imposed here. The output end of the first linear actuator 35 is provided with a hanging shaft 32 for engaging the worktable 50. Specifically, the slide body 33 is equipped with a longitudinal linear actuator 37, which includes a propulsion cylinder and an L-shaped push plate. The first linear actuator 35 is mounted on the L-shaped push plate. A transverse transfer hook 53 is provided on one side of the worktable 50. The propulsion cylinder pushes the L-shaped push plate to move the first linear actuator 35 longitudinally, allowing the hanging shaft 32 to detachably engage with the transverse transfer hook 53. The first linear actuator 35 provides driving force to pull the worktable 50 laterally on the slide mechanism. This utility model uses the first linear actuator 35 to provide linear drive. The hanging shaft 32 at the output end of the first linear actuator 35 can quickly engage the worktable 50. The rotation of the pulley assembly 31 drives the worktable 50 to move, improving the smoothness and speed of the worktable 50's sliding movement on the slide mechanism and reducing friction loss.

[0024] The slide body 33 is also equipped with a lifting assembly 36. The lifting assembly 36 adopts a cylinder or hydraulic lifting device and a lifting guide assembly. The output end of the lifting assembly 36 is connected to the lower end of the pulley assembly 31. The upper end of the slide body 33 is also provided with a positioning bushing 34, and the upper end of the positioning bushing 34 is provided with a locking device 38. The locking device 38 includes a locking cylinder and other locking structures. The positioning bushing 34 and the locking device 38 are used to lock the worktable 50 when the lifting assembly 36 drives the pulley assembly 31 and the worktable 50 to rise or fall. Specifically, the lower end of the worktable 50 is provided with a positioning sleeve 54 with a positioning cavity. The positioning cavity of the positioning sleeve 54 is locked in place with the locking device 38 of the positioning bushing 34. When the lifting assembly 36 drives the pulley assembly 31 and the worktable 50 to fall, the positioning bushing 34 and the locking device 38 lock the worktable 50 by nesting the positioning sleeve 54. There are multiple positioning bushings 34, which are evenly distributed on the upper end of the slide body 33 for multi-point positioning. The number of positioning sleeves 54 is the same as the number of positioning bushings 34 and their positions correspond. This invention uses a positioning bushing 34 to unlock the movement and positioning states of the worktable 50 in conjunction with the lifting assembly 36. When the lifting assembly 36 lifts up, it can raise the pulley assembly 31 to contact the worktable 50 and quickly displace it, avoiding displacement interference between the worktable 50 and the positioning bushing 34 and ensuring the normal movement of the worktable 50. When the lifting assembly 36 lowers, it can drive the pulley assembly 31 and the worktable 50 to lower, so that the positioning bushing 34 and the locking device 38 on the slide body 33 contact the worktable 50 to form a lock, ensuring the stability of the worktable 50 during the processing.

[0025] In summary, this invention employs a linear actuator to provide linear drive, and the rotation of the pulley assembly 31 drives the displacement of the worktable 50, improving the smoothness and speed of the worktable 50's sliding movement on the slide mechanism and reducing frictional losses. By setting a positioning bushing 34 and a locking device 38, in conjunction with the lifting assembly 36's lifting action, they can contact the worktable 50 to form a lock, ensuring the stability of the worktable 50 during processing. This invention can greatly improve the efficiency, accuracy, and reliability of worktable 50 exchange. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0026] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
