Description

Technical Field

[0001] This utility model relates to the field of bridge cutting machine technology, and in particular to a centrally suspended swing head structure. Background Technology

[0002] Stone is a building material widely used in interior and exterior decoration design, curtain wall decoration, and public facility construction. Before being used in decoration and renovation, stone is usually cut into the required shape and size according to the application scenario. For application scenarios that require simple cutting, a purely mechanical cutting machine is usually sufficient to reduce procurement costs. For example, in scenarios such as panel furniture, washbasins, and window sills, the edges of the stone need to be ground. Common vertical grinding techniques include rounded and multi-step shapes, while inclined grinding generally requires a 45° angle. When switching between vertical and inclined grinding, the grinding motor can be switched back and forth between 90° and 45° to meet the processing requirements. Currently, the commonly used switching structure involves installing a rotating shaft in the middle of the grinding motor mounting base. The angle of the grinding wheel is adjusted by rotating the grinding motor, and the mounting base of the grinding motor is fixed after switching. However, this switching structure causes a large difference in horizontal and vertical displacement of the grinding wheel while adjusting the grinding wheel angle, increasing the difficulty of subsequent horizontal and vertical adjustments. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a center-suspended swing head structure with the guide structure on the outside of the arc trajectory of the grinding motor. In this way, when adjusting the angle, the height difference and horizontal displacement difference generated by the grinding wheel are smaller, reducing the amount of adjustment in the horizontal and vertical directions after the angle is changed, simplifying the operation process, and facilitating the changing of the grinding wheel angle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a centrally suspended swing head structure, including a vertical adjustment mechanism, a horizontal adjustment mechanism, and a tilt adjustment mechanism. The vertical adjustment mechanism includes a Z-axis dovetail groove fixing seat, a Z-axis dovetail groove sliding plate, and a Z-axis lead screw transmission pair. The Z-axis dovetail groove fixing seat is provided with a Z-axis dovetail groove and is vertically slidably connected to the Z-axis dovetail groove sliding plate. The Z-axis lead screw transmission pair connects the Z-axis dovetail groove fixing seat and the Z-axis dovetail groove sliding plate and can drive the Z-axis dovetail groove sliding plate to slide up and down vertically. The horizontal adjustment mechanism includes an X-axis dovetail groove fixing seat, an X-axis dovetail groove sliding plate, and an X-axis lead screw transmission pair fixedly installed on the Z-axis dovetail groove sliding plate. The dovetail slide plate of the X-axis is laterally slidably connected to the dovetail mounting base of the X-axis. The X-axis lead screw drive connects the dovetail slide plate and the dovetail mounting base of the X-axis and can drive the dovetail slide plate back and forth in the lateral direction. The tilt adjustment mechanism includes an arc-shaped guide plate fixed on the dovetail slide plate of the X-axis and a motor mounting plate that is installed in conjunction with the guide plate. The motor mounting plate is provided with an outer guide plate and an inner guide plate. The outer guide plate and the inner guide plate are both in conjunction with the motor mounting plate to form a guide groove that slides in conjunction with the guide plate. The outer guide plate and the inner guide plate can slide synchronously along the outer arc edge and the inner arc edge of the guide plate, respectively. The guide plate and the motor mounting plate are fixed by fasteners.

[0005] Furthermore, positioning blocks are respectively provided at both ends of the guide fixing plate facing the motor mounting plate. The positioning blocks allow the motor mounting plate to be quickly rotated to contact the positioning blocks when changing angles, enabling rapid adjustment and avoiding repeated adjustments.

[0006] Furthermore, a magnetic seat is provided on the Z-axis dovetail groove fixing seat, with the end of the magnetic seat contacting the far end of the guide fixing plate. The magnetic seat generates magnetic force to attract and fix the guide fixing plate to the motor mounting plate, increasing the fixing strength of the motor mounting plate. When adjusting the angle, it can first serve as an auxiliary fixation, and then be fixed with fasteners. At the same time, it also provides a certain auxiliary support for the guide fixing plate, making the end of the guide fixing plate stable and reducing deformation.

[0007] The guide fixing plate has two fixing positions for the motor mounting plate with internal threaded holes, and the motor mounting plate has screw fixing positions at the positions corresponding to the internal threaded holes. The guide fixing plate and the motor mounting plate are fixed at the corresponding fixing positions by screws.

[0008] A handle is provided on the outer guide plate.

[0009] The beneficial effects of this utility model are as follows: This utility model places the outer side of the angle circle, so that when adjusting the angle, the center of rotation is placed outside the motor mounting plate and close to the grinding wheel. After adjusting the angle, the height difference and horizontal displacement difference generated by the grinding wheel are smaller, reducing the adjustment distance of the X-axis and Z-axis after adjusting the angle, simplifying the operation process, and making it easier to change the angle; the addition of a magnetic seat not only facilitates the adjustment of the angle of the motor mounting plate, but also increases the rigidity of the motor mounting plate, making the motor run more smoothly and reducing vibration.

The bearing seat of the Z-axis lead screw transmission pair 3 is installed on the Z-axis dovetail groove fixed seat 1. The lead screw is installed on the bearing seat through the bearing. The lead screw nut is installed on the Z-axis dovetail groove sliding plate 2. The Z-axis lead screw transmission pair 3 drives the Z-axis dovetail groove sliding plate 2 to slide up and down in the vertical direction.

[0016] The lateral adjustment mechanism includes an X-axis dovetail groove mounting base 4, an X-axis dovetail groove slide plate 5, and an X-axis lead screw drive pair 6, all fixedly mounted on the Z-axis dovetail groove slide plate. The X-axis dovetail groove slide plate 5 and the X-axis dovetail groove mounting base 4 are laterally slidably connected. The X-axis lead screw drive pair 6 includes a lead screw, a bearing housing, and a lead screw nut. The lead screw nut is fixedly connected to the X-axis dovetail groove slide plate 5. The bearing housing is mounted on the X-axis dovetail groove mounting base 4. The lead screw is installed by the bearing housing through the bearing. Rotating the lead screw drives the X-axis dovetail groove slide plate 5 to slide back and forth in the lateral direction.

[0017] The tilt adjustment mechanism includes an arc-shaped guide plate 7 fixed on the X-axis dovetail groove slide plate 5, and a motor mounting plate 8 that is installed in conjunction with the guide plate 7. A grinding motor 9 is mounted on the motor mounting plate 8, and a grinding wheel 10 is provided on the output shaft of the grinding motor 9. The motor mounting plate 8 is provided with an outer guide plate 11 and an inner guide plate 12. The outer guide plate 11 and the inner guide plate 12 are both in conjunction with the motor mounting plate 8 to form a guide groove that slides in contact with the edge of the guide plate 7.
