Traditional slide table locking mechanisms often employ methods such as single bolt fastening, spring compression, or wedge block limiting, which have many limitations.

[0003] Patent publication number "CN 209551129 U" discloses "a manual slide locking mechanism, characterized by including a slide base, a slide, a slide locking block, a copper block, a locking nut, a pressure block, a nut seat, a copper nut, a lead screw, a handwheel, and a bearing; the slide base is provided with a guide rail; the inner side of the slide locking block is provided with a guide rail groove that mates with the guide rail; the side of the slide is provided with a fixing threaded hole; the copper block is placed in the fixing threaded hole; the upper left and right corners of the slide are provided with locking threaded holes; the upper left and right corners of the slide locking block are provided with bolt through holes; the nut seat is provided with a through hole; the copper nut is provided with a boss and a transmission threaded hole; the copper nut is installed on the nut seat by bolts; one end of the lead screw is screwed into the copper nut by threads, and the other end of the lead screw is connected to the handwheel by a bearing. This locking mechanism has a simple structure."

[0004] To address the aforementioned issues, existing slide table locking mechanisms suffer from uneven locking force distribution and easy loosening, making it difficult to meet the stringent stability requirements of high-precision machining. Relying on a single bolt for fastening is not only cumbersome and inefficient, but also prone to inconsistent locking forces in different parts due to human error, causing machining errors to accumulate and affecting machining accuracy and equipment lifespan.

[0005] To address these issues, this invention provides a slide locking mechanism. Utility Model Content

[0013] Beneficial effects

[0014] This invention provides a slide locking mechanism. Compared with the prior art, it has the following advantages:

[0015] 1. This slide locking mechanism achieves stable clamping through clamping plates and a double-threaded rod. The double-threaded rod drives the clamping plates to move synchronously in opposite directions, ensuring uniform distribution of clamping force and preventing displacement or deformation of the slide due to uneven force.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0025] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1 to 5 This application provides a sliding table locking mechanism for mechanical engineering, including a sliding table base 1 and a sliding table 2. Support plates 4 are fixedly installed on the left and right sides of the top surface of the sliding table base 1. A sliding rod 8 is fixedly installed between the two support plates 4. A bidirectional threaded rod 7 is rotatably installed between the two support plates 4. The bidirectional threaded rod 7 is located below the sliding rod 8. The threads on the outer center sides of the bidirectional threaded rod 7 have opposite directions of rotation. A slider 10 is slidably installed on the outer side of the sliding rod 8. Two sliders 10 are respectively screwed onto the outer sides of the threads of the bidirectional threaded rod 7 with different directions of rotation. A clamping plate 9 is fixedly installed on the front side of the slider 10. The outer side of the clamping plate 9 is engaged with the inner side of the clamping plate 9. A main motor 6 is fixedly installed on the outer side of the support plate 4. The motor shaft of the main motor 6 passes through the interior of the support plate 4 and is fixedly connected to the slider 10.

[0027] In this embodiment, the main motor 6 on the outer side of the support plate 4 is first started. The main motor 6 drives the bidirectional threaded rod 7 to rotate. Since the threads on both sides of the outer center of the bidirectional threaded rod 7 have opposite directions of rotation, the two sliders 10 screwed to the outer sides of the threads with different directions of rotation will slide along the slide rod 8 during its rotation. The clamping plate 9 fixedly installed on the front side of the slider 10 clamps the slide table 2 as the slider 10 moves. When the two clamping plates 9 move to close contact with the slide table 2, the slide table 2 can be clamped and fixed. The contact surface between the clamping plate 9 and the slide table 2 is provided with soft silicone, which can prevent the clamping plate 9 from damaging the surface of the slide table 2 and increase the friction between the clamping plate 9 and the slide table 2, thereby improving the stability of the locking.

[0028] Reference Figures 1 to 5In one aspect of this embodiment, a push-fixing assembly 3 is provided on the top side of the slide base 1. The push-fixing assembly 3 includes a support block 31, which is fixedly installed on the top side of the slide base 1. A hydraulic push rod 32 is fixedly installed on the rear side of the support block 31. The output end of the hydraulic push rod 32 passes through the support block 31 and is fixedly installed on the assembly frame 34. A worm gear 33 is rotatably connected to the front and rear sides inside the assembly frame 34. A worm motor 35 is fixedly installed on the front side of the assembly frame 34. The motor shaft of the worm motor 35 passes through the assembly frame 34 and is fixedly connected to the worm gear 33. A fixed shaft 37 is rotatably installed on the inner side of the assembly frame 34. A worm wheel 36 is fixedly installed on the outer side of the fixed shaft 37. Fixed rods 38 are fixedly installed on the sides of both worm wheels 36. The sides of both worm wheels 36 mesh with the sides of the worm gear 33. A support wheel 5 is fixedly installed on the bottom side of the assembly frame 34. Soft silicone is provided on the contact surface between the clamping plate 9 and the slide 2.

[0029] In this embodiment, the worm motor 35 is first started to rotate, causing the worm 36 to start rotating. The worm 33 meshes with the worm wheels 36 on both sides, causing the fixing rod 38 fixed on the outside of the worm wheel 36 to open to a suitable position as the worm wheel 36 rotates. Then, the hydraulic push rod 32 is started to push the component frame 34 forward until the fixing rod 38 is close to the side of the slide table 2. The bottom support wheel 5 further supports and pushes the fixing component 3. The slide table 2 is clamped synchronously with the clamping plate 9 under the drive of the bidirectional threaded rod 7, thereby forming a multi-directional cooperative constraint structure.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle: The main motor 6 is started to drive the bidirectional threaded rod 7 to rotate, which drives the slider 10 to slide along the sliding rod 8 in opposite directions, so that the clamping plate 9 clamps the slide table 2. The soft silicone on the surface of the clamping plate 9 enhances the friction and protects the surface of the slide table. Then, the worm motor 35 is started, and the worm 33 and worm wheel 36 mesh and drive the fixed rod 38 to rotate to a predetermined angle. Then, the hydraulic push rod 32 is started to push the component frame 34 forward until the fixed rod 38 presses against the side of the slide table 2. The bottom support wheel 5 ensures smooth movement and provides support. The fixed rod 38 and the clamping plate 9 work synchronously to form a three-dimensional constraint on the slide table 2 from the side and front and back directions, which improves the locking stability and positioning accuracy and is suitable for reliable fixing needs under different working conditions.
