Description

Technical Field

[0001] This utility model relates to the technical field of gantry machining centers, specifically to an auxiliary support device for preventing sagging and shaking of the long lead screw of a gantry beam. Background Technology

[0002] Existing technologies typically employ pre-stretching of the lead screw to compensate for thermal deformation caused by temperature rise, thereby ensuring the accuracy and stability of the transmission system and improving the rigidity of the lead screw. However, as the length of the lead screw increases, the effect gradually decreases, meaning that bending deformation easily occurs in the middle of the lead screw, leading to vibration problems during transmission.

[0003] Currently, in order to solve the above-mentioned technical problems, an auxiliary support structure is usually used to support the middle part of the lead screw. However, most auxiliary support structures are very complex and may require the cooperation of electrical, hydraulic and pneumatic systems, which makes them relatively difficult to control and costly.

[0004] Meanwhile, if a support shaft is used to support the bent and deformed part of the lead screw due to its own weight, the support shaft will retract when the lead screw nut passes by and extend after the lead screw nut passes by. This solves the problem of the lead screw bending due to its own weight. However, this technology is mainly applied to the bed and cannot solve the problem of the lead screw sagging on the crossbeam, nor can it solve the problem of lead screw vibration. Utility Model Content

[0005] To address the aforementioned problems, namely, how to prevent the lead screw on the crossbeam from sagging and vibrating, this utility model proposes an auxiliary support device for preventing sagging and vibration of the long lead screw of a gantry crossbeam. The device includes a crossbeam body, on which a lead screw body is mounted. A saddle is slidably connected to the crossbeam body, and the saddle is threadedly connected to the lead screw body. Two support seats are slidably connected to the crossbeam body, with each support seat positioned on one side of the saddle. Magnetic seats are mounted on the two side surfaces of the saddle near the two support seats. An upper magnet is mounted on the side surface of each support seat near the saddle, corresponding to the magnetic seats. A fixed stop is installed in the middle of the crossbeam body to prevent the support seats from sliding. The support seats are sleeved with the lead screw body.

[0006] A further feature of this invention is that a collar is also installed on the support base, and the support base is sleeved with the lead screw body through the collar.

[0007] A further feature of this invention is that magnetic blocks are also installed on both sides of the fixed block near the two support seats, and a lower magnet is also installed on the side surface of the support on which the upper magnet is installed, corresponding to the magnetic blocks.

[0008] The beneficial effects of this utility model are as follows:

[0009] By installing support seats, the lead screw body can be supported and limited, further preventing the lead screw body from sagging or shaking. At the same time, the cooperation between the magnetic seat and the upper magnet allows the sliding saddle to drive the support seats to move. With the cooperation of the fixed stop, at least one support seat can always be located in the middle position of the lead screw body, providing support and limiting for the middle part of the lead screw body, so as to better support the lead screw body and suppress the shaking of the lead screw body.

[0018] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] This utility model proposes an auxiliary support device for preventing sagging and shaking of the long lead screw body 11 of a gantry beam. It includes a beam body 1, on which a lead screw body 11 is installed. The two ends of the lead screw body 11 are connected to the beam body 1 by mounting seats, that is, the mounting seats are connected to the beam body 1 by bolts. The two ends of the lead screw body are rotatably connected to the two mounting seats. A sliding saddle 2 is also slidably connected to the beam body 1. The sliding saddle 2 is threadedly connected to the lead screw body 11. Driving the lead screw body 11 to rotate can drive the sliding saddle 2 to slide along the lead screw body 11.

[0020] Two support seats 3 are slidably connected to the crossbeam body 1. The two support seats 3 are respectively set on both sides of the slide saddle 2. Magnetic seats 21 are bolted to the two side surfaces of the slide saddle 2 near the two support seats 3. An upper magnet 31 is bolted to the side surface of the support seat 3 near the slide saddle 2. The upper magnet 31 is set to correspond to the magnetic seat 21, that is, the upper magnet 31 and the magnetic seat 21 are set at the same height. When the slide saddle 2 moves to the vicinity of the support seat 3, the magnetic seat 21 on the slide saddle 2 and the upper magnet 31 on the support seat 3 can attract each other under the action of magnetic force, thereby enabling the slide saddle 2 to drive the support seat 3 to move accordingly.

[0021] A fixing block 4 is bolted to the middle of the crossbeam body 1. The fixing block 4 is positioned above the lower surface of the support base 3 but below the lower surface of the slide saddle 2 to prevent the support base 3 from sliding and to avoid interfering with the movement of the slide saddle 2. The support base 3 is sleeved with the lead screw body 11, thereby providing support and limiting for the lead screw body 11, preventing it from sagging or vibrating.

[0022] A collar 32 is also fixedly installed on the support base 3. The collar 32 is made of polytetrafluoroethylene material. The support base 3 is connected to the lead screw body 11 through the collar 32.

[0023] The fixed stop 4 is designed as an inverted T-shape. Magnets 41 are bolted to the two side surfaces of the fixed stop 4 near the two support seats 3. A lower magnet 33 is also installed on the side surface of the support seat 3 corresponding to the upper magnet 31, meaning the lower magnet 33 is at the same height as the magnet 41. When the support seat 3 slides near the fixed stop 4, the lower magnet 41 on the support seat 3 and the magnet 41 on the fixed stop 4 attract each other under magnetic force. This causes the support seat 3 to press tightly against the fixed stop 4. Since the fixed stop 4 is higher than the lower surface of the support seat 3, when the sliding saddle 2 passes the fixed stop 4, the support seat 3 will be blocked at the fixed stop 4 and will not continue to move with the sliding saddle 2.

[0024] Movement Process: When the sliding saddle 2 moves to the left of the fixed stop 4, the magnetic seat 21 on the left side of the sliding saddle 2 will attract the upper magnet 31 on the left support seat 3 under the action of magnetic force, thus causing the sliding saddle 2 to slide the support seat 3 to the left. When the sliding saddle 2 moves to the right, under the action of magnetic force, the sliding saddle 2 can continue to move the left support seat 3. When it reaches the fixed stop 4, since the height of the fixed stop 4 is higher than the lower surface of the support seat 3 but lower than the lower surface of the sliding saddle 2, the sliding saddle 2 will slide past the fixed stop 4 and separate from the left support seat 3. As the slide continues to move to the right, the lower magnet 33 of the left-side support 3 will attract the magnet 41 on the fixed stop 4, thus securing it stably at the fixed stop 4. The slide saddle 2, having slid past the fixed stop 4, will attract the upper magnet 31 of the right-side support 3, causing it to move. This continues until the slide saddle 2 moves it to the left and back to the fixed stop 4. At this point, the lower magnet 33 on the right-side support attracts the magnet 41, disengaging the slide saddle 2 from the right-side support 3 and attracting the left-side support 3, causing it to move to the left and detach from the fixed stop 4. This ensures that regardless of the slide saddle 2's movement, one support 3 is always positioned at the fixed stop 4, providing support and limiting the middle position of the lead screw.

[0025] In summary, this utility model, by installing the support base 3, can support and limit the lead screw body 11, further preventing the lead screw body 11 from sagging or shaking. At the same time, the cooperation between the magnetic base 21 and the upper magnet 31 allows the sliding saddle 2 to drive the support base 3 to move. With the cooperation of the fixed stop block 4, it can always be ensured that at least one support base 3 is located in the middle position of the lead screw body 11, which plays a supporting and limiting role in the middle part of the lead screw body 11, so as to better support the lead screw body 11 and suppress the shaking of the lead screw body 11.
