Technical Field
[0001] This utility model relates to the field of mechanical equipment technology, specifically to an auxiliary device for installing cutting tools for CNC gantry milling machines. Background Technology
[0002] A gantry milling machine, also known as a gantry milling machine, is a milling machine with a gantry frame and a horizontal long bed. Multiple milling cutters can be used on a gantry milling machine to process surfaces simultaneously, resulting in high processing accuracy and production efficiency. It is suitable for processing planes and inclined surfaces of large workpieces in batch and mass production. CNC gantry milling machines can also process spatial curved surfaces and some special-shaped parts.
[0003] An existing patent (publication number: CN216398179U) discloses a tool mounting auxiliary device for CNC gantry milling machines, including a base. Two sets of vertical columns are symmetrically fixed on both sides of the upper surface of the base. The tops of each set of vertical columns are connected together by a top beam. A horizontal guide rail is slidably mounted inside each set of vertical columns, perpendicular to the vertical columns. A sliding frame is slidably mounted inside the horizontal guide rail, and a fixed frame is fixed between two sliding frames. An electric telescopic rod is fixed between each set of vertical columns. The advantages are: reasonable structural design, convenient movement, the tool holder can move horizontally and vertically, it can provide auxiliary support for the tool head during installation and removal, and the anti-tilting plate prevents the device from tipping over during tool installation or removal, improving the safety and convenience of tool head installation and removal. In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. The cutter heads of existing gantry milling machines are relatively large, especially those for machining large workpieces, which are even larger in size and heavier in weight. These cutter heads are mostly installed with the assistance of small hoisting equipment, making the operation cumbersome and significantly reducing the ease of installation; 2. The height of existing gantry milling machine cutter head installation auxiliary devices is mostly a fixed structure, making it impossible to adjust the height of the device according to the different heights of the gantry milling machine. When the height of the gantry milling machine is different, different cutter head installation auxiliary devices need to be replaced, thus significantly reducing the practicality of the device and failing to meet people's usage needs. Utility Model Content
[0004] The purpose of this utility model is to provide an auxiliary device for installing CNC gantry milling cutters, in order to solve the problems mentioned in the background art, that the cutter heads of existing gantry milling machines are relatively large, especially those for machining large workpieces, which are even larger in size and heavier in weight. Such cutter heads are mostly installed with the assistance of small lifting equipment, which is cumbersome and greatly reduces the convenience of cutter head installation. In addition, the height of existing gantry milling machine cutter head installation auxiliary devices is mostly a fixed structure, which cannot be adjusted according to the different heights of gantry milling machines, thus greatly reducing the practicality of the device. To achieve the above objectives, this utility model provides the following technical solution: A tool mounting auxiliary device for CNC gantry milling machines, comprising a moving component, an electric motor embedded in the bottom of the moving component, guide grooves formed at the four outer corners of the top of the moving component, an installation groove formed in the middle of the top of the moving component, a threaded rod provided at the bottom of the installation groove via a bearing, a threaded sleeve provided on the outside of the threaded rod, a positioning plate provided at the top of the threaded sleeve, guide rods formed at the four corners of the bottom of the positioning plate, a fixed seat provided at the top of the threaded sleeve, a support plate provided on one side of the fixed seat, a control rod provided at the bottom of the support plate, a connecting shaft provided at the top of the fixed seat, a placement seat provided at the top of the connecting shaft via a bearing, a plurality of slots formed on the outside of the bottom of the placement seat, a placement groove formed in the middle of the top of the placement seat, and an anti-slip pad provided at the bottom of the placement groove.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 4This utility model provides a technical solution: a tool installation auxiliary device for CNC gantry milling, including a moving component 1, an electric motor 2 embedded in the bottom of the moving component 1, guide grooves 3 at the four corners of the top of the moving component 1, an installation groove 4 in the middle of the top of the moving component 1, a threaded rod 5 with a bearing at the bottom of the installation groove 4, a threaded sleeve 6 on the outside of the threaded rod 5, a positioning plate 7 at the top of the outside of the threaded sleeve 6, guide rods 8 at the four corners of the bottom of the positioning plate 7, a fixed seat 9 at the top of the threaded sleeve 6, a support plate 10 on one side of the fixed seat 9, a control rod 11 at the bottom of the support plate 10, a connecting shaft 12 at the top of the fixed seat 9, a placement seat 13 with a bearing at the top of the connecting shaft 12, several slots 14 on the outside of the bottom of the placement seat 13, a placement groove 15 in the middle of the top of the placement seat 13, and an anti-slip pad 16 at the bottom of the placement groove 15.
[0021] In this embodiment, as Figure 1 As shown, the movable component 1 includes a base 101, with casters 102 at each of the four corners of the bottom end of the base 101, and a sleeve post 103 at the center of the top end of the base 101.
[0022] In this embodiment, as Figure 3 As shown, the guide groove 3 and the guide rod 8 are designed to be slidingly connected; this increases the stability of the threaded sleeve 6 during movement and prevents the threaded sleeve 6 from rotating with the rotation of the threaded rod 5 during movement.
[0023] In this embodiment, as Figure 4 As shown, the internal dimensions of the mounting groove 4 are consistent with the external dimensions of the threaded sleeve 6; this ensures that the threaded sleeve 6 moves in a single direction, preventing it from shifting or tilting during movement, thereby increasing the stability of the threaded sleeve 6 during movement.
[0024] In this embodiment, as Figure 2 As shown, the central axis of the threaded rod 5 is aligned with the central axis of the motor 2; this allows for adjustment of the height of the cutter head mounting auxiliary device according to the different heights of the gantry milling machine, enabling the cutter head mounting auxiliary device to install tools on gantry milling machines of different heights and sizes, thereby greatly improving the practicality of the CNC gantry milling cutter mounting auxiliary device.
[0025] In this embodiment, as Figure 2 As shown, the support plate 10 and the control rod 11 are connected by a thread; this fixes the placement seat 13 after the cutter head angle is finely adjusted, preventing the placement seat 13 from causing the cutter head to rotate during use, thereby increasing the stability of the placement seat 13 during use.
[0026] In this embodiment, as Figure 1As shown, the placement seat 13 rotates around the central axis of the connecting shaft 12; this allows for fine-tuning of the angle of the cutter head at the top of the placement seat 13 according to the user's needs, solving the problem that the gantry milling cutter tool needs to be assisted in its installation due to its heavy weight, thus greatly improving the convenience of the gantry milling cutter tool during installation.
[0027] The usage and advantages of this utility model are as follows: The working process of this CNC gantry milling cutter mounting auxiliary device is as follows:
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, the cutter head of the gantry milling machine is placed in the top placement groove 15 of the placement seat 13. The anti-slip pad 16 increases the friction between the placement seat 13 and the cutter head, preventing displacement or offset of the cutter head during installation. Then, the base 101 is pushed, causing the base 101 to move the placement seat 13 below the installation position of the gantry milling machine tool with the cooperation of the sleeve column 103 and the threaded sleeve 6 via the universal wheel 102. Then, the motor 2 is started by the controller. At this time, the motor 2 drives the threaded rod 5 to rotate, and the threaded rod 5 drives the threaded sleeve 6 to move upward with the cooperation of the guide rod 8 and the guide groove 3. At the same time, the threaded sleeve 6 drives the cutter head to move upward synchronously through the placement seat 13, so that the cutter head moves to the designated position. This realizes the height adjustment of the cutter head installation auxiliary device according to the different heights of the gantry milling machine, so that the cutter head installation auxiliary device can be adjusted for different heights. The fixtures for a gantry milling machine of the same height and size are installed. Then, by rotating the placement seat 13, the placement seat 13 drives the cutter head to rotate at an angle with the connecting shaft 12. This allows the placement seat 13 to move the cutter head to an angle consistent with the tool mounting bracket of the gantry milling machine. This enables fine-tuning of the cutter head at the top of the placement seat 13 according to the user's needs. This solves the problem that the gantry milling fixtures are heavy and require small lifting equipment for auxiliary installation, thus greatly improving the convenience of installation. Then, by rotating the control rod 11, the control rod 11 is engaged in the slot 14 with the threaded engagement of the support plate 10, thus fixing the placement seat 13 after the cutter head angle is finely adjusted. This prevents the placement seat 13 from causing the cutter head to rotate during use, thereby increasing the stability of the placement seat 13 during use.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
