A mechanical equipment and its limit device proposed in the Chinese utility model patent application number: CN201521142719.5. The limit device includes a fixed component and a limit stop block that are detachably connected. The limit stop block is used to prevent two rotating parts from continuing to rotate along the rotation direction when they rotate relative to each other to the maximum angle. The fixed component is used to fix the limit stop block with different sizes in the rotation direction on one of the rotating parts, so that the rotating part and the other rotating part can rotate relative to each other to different maximum angles. The utility model can replace limit stop blocks with different sizes to achieve mechanical limit and limit protection under different working conditions.

[0003] However, there are still some deficiencies in the existing mechanical equipment limit devices during use that need to be improved. Traditional limit devices often have a simple structure and can only perform fixed-degree limits in a single direction, and cannot flexibly adapt to different working scenarios and complex and changeable limit requirements. Their angle adjustment range is very limited and it is difficult to meet diverse working angle requirements. Most of the existing devices cannot achieve precise position adjustment in the horizontal and vertical directions, resulting in inaccurate limits and affecting the normal operation and machining accuracy of the equipment. Therefore, we make improvements and propose a mechanical equipment limit device. Summary of the Utility Model

[0024] Embodiment 1: Please refer to Figures 1 - 5, a mechanical equipment limiting device, including an L-shaped fixing plate 1, the L-shaped fixing plate 1 is connected to a limiting vertical angle adjusting plate 2, an arc-shaped keyway 201 is provided on the limiting vertical angle adjusting plate 2, an adjusting fixed threaded slide rod 202 is arranged in the arc-shaped keyway 201, the limiting vertical angle adjusting plate 2 is connected to a connecting wedge 3, a horizontal adjusting rotating block 4 is arranged on the side of the connecting wedge 3, a sector arc groove 401 is provided on the horizontal adjusting rotating block 4, an adjusting fastening pin 402 is arranged on the sector arc groove 401, the horizontal adjusting rotating block 4 is arranged on a connecting disc 403, a limiting shaft 5 is arranged on the side of the connecting disc 403, a supporting beam block 6 is arranged on the side of the limiting shaft 5, an I-beam 7 is arranged above the supporting beam block 6, an n-shaped sliding adjusting limiting block 8 is arranged above the I-beam 7, and a detachable limiting rod 11 is arranged on the n-shaped sliding adjusting limiting block 8.

[0025] Threaded holes 701 are provided on the I-beam 7 and the n-shaped sliding adjusting limiting block 8, and the threaded holes 701 on the I-beam 7 and the threaded holes 701 provided on the n-shaped sliding adjusting limiting block 8 are on the same horizontal line. An adjusting threaded rod 9 is threadedly engaged in the threaded hole 701 of the I-beam 7, and an adjusting knob 901 is arranged at the end of the adjusting threaded rod 9. A guiding column 10 is arranged on the side of the adjusting threaded rod 9, and the guiding column 10 passes through the upper part of the I-beam 7. A pin hole 12 is provided on the supporting beam block 6.

[0026] The angle of the arc-shaped keyway 201 is α, and the range of α is 25° < α < 45°. The angle of the sector arc groove 401 is β, and the range of β is 30° < α < 60°. A combined block 13 is arranged above the n-shaped sliding adjusting limiting block 8.

[0027] The L-shaped fixing plate 1, as a basic fixing component, is connected to the limiting vertical angle adjusting plate 2. The arc-shaped keyway 201 on the limiting vertical angle adjusting plate 2 provides a track for the movement and fixation of the adjusting fixed threaded slide rod 202. By adjusting the position of the adjusting fixed threaded slide rod 202 in the arc-shaped keyway 201, the vertical angle of the limiting vertical angle adjusting plate 2 can be changed to adapt to different working requirements.

[0028] The limiting vertical angle adjusting plate 2 is connected to the connecting wedge 3. The sector arc groove 401 and the adjusting fastening pin 402 arranged on the horizontal adjusting rotating block 4 on the side of the connecting wedge 3 enable the horizontal adjusting rotating block 4 to perform angular adjustment in the horizontal direction within a certain angle range and be fixed by the adjusting fastening pin 402. The horizontal adjusting rotating block 4 is installed on the connecting disc 403, providing the possibility of horizontal adjustment for the entire device.

[0029] The limiting shaft 5 on the side of the connecting plate 403 and the supporting beam block 6 work together to support and limit the device. The I-beam 7 above the supporting beam block 6 cooperates with the n-type sliding adjustment limiting block 8. The detachable limiting rod 11 on the n-type sliding adjustment limiting block 8 can be installed or removed as needed to achieve different limiting functions.

[0030] Threaded holes 701 on the I-beam 7 and the n-type sliding adjustment limiting block 8 that are on the same horizontal line are used to install the adjusting threaded rod 9. By rotating the adjusting knob 901, the adjusting threaded rod 9 is driven to rotate. Due to the threaded fit between the adjusting threaded rod 9 and the I-beam 7, the n-type sliding adjustment limiting block 8 can move horizontally along the I-beam 7, thereby precisely adjusting the limiting position. The guiding column 10 on the side of the adjusting threaded rod 9 passes through the upper part of the I-beam 7 to play a guiding role, ensuring the smoothness and accuracy of the movement of the n-type sliding adjustment limiting block 8. The pin hole 12 on the supporting beam block 6 can be used to install a fixing pin to further enhance the stability of the device.

[0031] The angle α of the arc-shaped keyway 201 is in the range of 25° < α < 45°, and the angle β of the sector arc groove 401 is in the range of 30° < α < 60°. The setting of these angle ranges provides a suitable amplitude for the angle adjustment of the device in the vertical and horizontal directions to meet diverse limiting requirements. The combined block 13 above the n-type sliding adjustment limiting block 8 can be combined with other components for use to expand the functions of the device.

[0032] The specific working process of the mechanical equipment limiting device: First, fix the L-shaped fixing plate 1 at a suitable position on the mechanical equipment as the basic support for the entire device. When adjusting the vertical angle of the limiting device, loosen the adjusting fixed threaded rod 202 so that it moves within the arc-shaped keyway 201. According to actual needs, move the adjusting fixed threaded rod 202 to a suitable position and then tighten it to change the vertical angle of the limiting vertical angle adjusting plate 2.

[0033] Next, if adjusting the angle in the horizontal direction, loosen the adjusting fastening pin 402 to make the horizontal adjustment rotating block 4 rotate to the required angle within the range of the sector arc groove 401, and then tighten the adjusting fastening pin 402 for fixation.

[0034] Then, by rotating the adjusting knob 901, the adjusting threaded rod 9 is driven to rotate in the threaded hole 701 of the I-beam 7. Due to the threaded fit, the adjusting threaded rod 9 pushes the n-type sliding adjustment limiting block 8 to move horizontally along the I-beam 7. During this process, the guiding column 10 passes through the upper part of the I-beam 7 to ensure the stable and accurate movement direction of the n-type sliding adjustment limiting block 8.

[0035] According to specific limiting requirements, it is possible to choose to install a detachable limiting rod 11 on the n-type sliding adjustment limiting block 8. If it is necessary to further enhance the stability of the device, a pin can also be inserted into the pin hole 12 of the support beam block 6.

[0036] In addition, the angle α of the arc-shaped keyway 201 is in the range of 25° < α < 45°, and the angle β of the sector arc groove 401 is in the range of 30° < α < 60°, ensuring appropriate amplitude and precision for angle adjustment in the vertical and horizontal directions. The combined block 13 above the n-type sliding adjustment limiting block 8 can be combined with other components according to actual situations to achieve more complex limiting functions.

[0037] The above embodiments are only used to illustrate the present invention rather than to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement made to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention are covered by the scope of the claims of the present invention.
