Technical Field

[0001] This utility model relates to the technical field of gantry machining centers, specifically a movable gantry frame for gantry machining centers. Background Technology

[0002] A gantry machining center is a machining center where the Z-axis of the spindle is perpendicular to the worktable. Its overall structure is a large machining center with a portal frame consisting of two columns and a top beam, with a crossbeam in the middle of the two columns. It is particularly suitable for machining large and complex-shaped workpieces. The gantry frame is a crucial structural component of the gantry machining center, used to mount the machining equipment and move it.

[0003] The existing mobile gantry cranes used in gantry machining centers have the following drawbacks during use: the guide rails of the gantry crane are generally open, so during the machining process, debris, dust and other impurities can easily enter the inner cavity of the guide rails, affecting the stability of the gantry crane when it moves. Therefore, there is room for improvement. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] Example 1:

[0024] Combination Figure 1-4 As shown, this embodiment provides a movable gantry for a gantry machining center, including: a main body 100.

[0025] The main structure 100 includes symmetrically arranged guide rails 110, multiple rollers 120 rotatably mounted on the inner wall of the guide rails 110, a movable seat 130 movably fitted into and extending out of the guide rails 110, a gantry frame body 140 mounted on the opposite movable seat 130, a transmission component 150 rotatably mounted in the inner cavity of the guide rails 110 and passing through the movable seat 130, a drive component 160 mounted on one side of the base and meshing with the transmission component 150, guide rollers 170 symmetrically mounted on both sides of the guide rails 110, and a dustproof belt 180 with one end fixed to one side of the movable seat 130 and the other end sequentially passing around the guide rollers 170 on both sides and fixed to the other side of the movable seat 130.

[0026] The guide rail 110 is used to mount the movable seat 130 and limit the movement of the movable seat 130. Multiple fixed shafts 111 are fixed in an array between the relatively inner sidewalls of the guide rail 110. The roller 120 is rotatably sleeved on the fixed shaft 111. The movable seat 130 is fitted into the guide rail 110, and the bottom end of the movable seat 130 is close to the roller 120. With this arrangement, when the movable seat 130 moves, it drives the roller 120 to rotate, thereby reducing the moving friction between the guide rail 110 and the movable seat 130 and improving the smoothness of the movement of the movable seat 130.

[0027] The movable seat 130 is used to fix the gantry frame body 140 and drive the gantry frame body 140 to move. The gantry frame body 140 is used to install the processing device and drive the processing device to move, so as to facilitate the processing of the workpiece.

[0028] The transmission component 150 is used to drive the movable seat 130 to move. It includes a threaded rod 151 rotatably mounted on the inner wall of the guide rail 110 and a worm gear 152 fixed to the end of the threaded rod 151 and extending out of the guide rail 110. The movable seat 130 has a threaded hole 131 through which the threaded rod 151 passes, and the threaded rod 151 meshes with the threaded hole 131. Additionally, the drive component 160 includes a motor 161 mounted on one side of the guide rail 110 and a worm gear 162 fixed to the shaft of the motor 161. Worm 162 meshes with worm gear 152. With this configuration, when motor 161 starts, it drives worm 162 to rotate. The rotation of worm 162 drives worm gear 152 to rotate. The rotation of worm gear 152 drives threaded rod 151 to rotate. The rotation of threaded rod 151 drives movable seat 130 to move. The movement of movable seat 130 drives the entire gantry frame to move. In addition, the transmission between worm 162 and worm gear 152 is a unidirectional transmission, which can ensure that after the drive component 160 stops, the transmission rod can rotate due to external factors.

[0029] The guide roller 170 is used to install the dustproof belt 180 and facilitate the rotation of the dustproof belt 180. One end of the dustproof belt 180 is fixed to one side of the movable seat 130, and the other end passes around the guide rollers 170 on both sides and is fixed to the other end of the movable seat 130, thus sealing the top of the entire guide rail 110, thereby effectively preventing debris, dust and impurities from entering the inner cavity of the guide rail 110. In addition, the dustproof belt 180 is made of high temperature resistant and flame retardant rubber material to prevent high temperature debris generated during processing from damaging the dustproof belt 180.

[0030] The working principle and usage process of this utility model are as follows: When the gantry frame body 140 moves, the motor 161 is started. The rotation of the motor 161 drives the worm gear 162 to rotate, which in turn drives the worm wheel 152 to rotate. The rotation of the worm wheel 152 drives the threaded rod 151 to rotate, which in turn drives the movable seat 130 to move. The movement of the movable seat 130 drives the entire gantry frame to move. At this time, the movable seat 130 moves at the top of the roller 120. The roller 120 changes the friction between the movable seat 130 and the inner bottom wall of the guide rail 110 into rolling friction, which greatly reduces the friction between the movable seat 130 and the guide rail 110 when the movable seat 130 moves. At the same time, the movement of the movable seat 130 drives the dustproof belt 180 to rotate. The dustproof belt 180 can seal the top of the guide rail 110 to prevent external debris and dust from entering the inner cavity of the guide rail 110.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
