Description

Technical Field

[0001] This utility model belongs to the technical field of high-speed machining centers, specifically relating to a 45° follower tool magazine support suitable for moving column gantry machining centers. Background Technology

[0002] With the rise of the new energy vehicle industry in recent years, auto parts manufacturers are also constantly keeping up and increasing their production capacity. Parts such as battery boxes and engine compartments are usually made of aluminum through die casting, and small gantry CNC milling machines have gradually become the main processing equipment for these parts. The main processing of aluminum die castings mainly involves drilling and small-plane milling, so the actual processing time for each process is relatively short, requiring frequent tool changes.

[0003] Currently, most small gantry CNC milling machines use fixed tool magazines, which are permanently installed inside or outside the machine tool. Each time a tool is changed, the crossbeam must return to the tool magazine's position, increasing tool change time and impacting overall machining efficiency. This is especially true when the machining position is far from the worktable, where the crossbeam's reciprocating tool change stroke consumes a significant amount of time, severely affecting machine tool efficiency in a factory assembly line production environment. Eliminating this reciprocating tool change stroke, allowing the machine to change tools without moving the crossbeam during machining, would effectively improve machining efficiency. Furthermore, the tool magazines on existing small gantry CNC milling machines are located behind the worktable within the machining area. Over time, this can lead to water and chip accumulation in the tool magazine's internal space, requiring regular cleaning and placing higher demands on waterproofing performance. Utility Model Content

[0004] The technical problem this invention aims to solve is to address the shortcomings of existing technologies by providing a 45° follow-up tool magazine support suitable for moving-column gantry machining centers. This tool magazine support is lightweight, which helps to shorten the tool changer arm length, ensures the stability of the tool magazine's tool changing action, and saves space. It also prevents water and chip accumulation in the tool magazine space. When this tool magazine support is used on the machine tool, the tool magazine can move with the crossbeam, allowing for direct tool changing within the machine tool's machining area. Tool changing time is short, significantly improving machining efficiency, especially in machining scenarios requiring frequent tool changes.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a 45° follower tool magazine bracket suitable for a moving column gantry machining center, comprising a frame-shaped bracket body welded from steel plates with a thickness of 16-25mm. A first mounting plate and a second mounting plate are vertically welded to the outer edges of the bracket body at the front and rear, respectively. The first mounting plate is welded to the front side of the bracket body in the length direction, and the second mounting plate is welded to one side of the bracket body in the width direction. The included angle between the orthographic projections of the first mounting plate and the second mounting plate on the horizontal plane is 45°. The front side of the first mounting plate faces the front of the second mounting plate. The first mounting plate is used for surface contact and fixed connection of the tool magazine to achieve a 45° inclined installation of the tool magazine. The second mounting plate is used for surface contact and fixed connection of one side of the crossbeam of the moving column gantry machining center.

[0006] The tool magazine bracket of this utility model is welded from a steel plate with a thickness of 16-25mm. While ensuring the overall rigidity, strength and stability of the tool magazine bracket, the weight of the tool magazine bracket can be greatly reduced.

[0007] After installation, the tool magazine bracket of this utility model is directly fixed to one side of the crossbeam of the moving column gantry machining center. A slide saddle is installed on the linear guide along the Y-axis on the front side of the crossbeam, and a movable ram is installed on the slide saddle. The machine tool spindle is mounted on the ram. When the crossbeam moves, the tool magazine bracket can move synchronously with the crossbeam along with the tool magazine. Compared with the traditional fixed tool magazine tool changing method, after the machine tool adopts the tool magazine bracket of this utility model, because the tool magazine can move with the crossbeam, tool changing can be performed directly in the machine tool machining area, and the tool changing time is short. Especially in machining scenarios that require frequent tool changes, the machining efficiency of the machine tool can be greatly improved.

[0008] This tool magazine bracket allows for a 45° tilt installation of the tool magazine, reducing the distance between the tool magazine cam rotating box and the tool disc, thereby shortening the tool changer arm length and correspondingly reducing the rotation radius of the tool changer arm. It also reduces the impact of the tool changer arm's own weight when it is extended. This helps ensure the stability of the tool magazine's tool changing operation, saves space, makes the overall machine tool structure more compact, and prevents water and chip accumulation in the tool magazine space.

[0009] Preferably, a first support plate and a second support plate are horizontally welded to the upper and lower parts of the second mounting plate, respectively. A first vertical plate and a second vertical plate are welded to each other on the front side between the first support plate and the second support plate. A third vertical plate is welded to the front side of the second vertical plate at a 45° angle. The two sides of the first mounting plate are welded to the first vertical plate and the third vertical plate, respectively. A plurality of first stiffeners are welded between the first support plate and the second support plate. A plurality of second stiffeners are welded between the first vertical plate and the second vertical plate. A plurality of third stiffeners are welded between the second vertical plate and the first mounting plate.

[0010] As a further preferred embodiment, the first support plate, the second support plate, the first vertical plate, the second vertical plate, the plurality of first stiffening plates, the plurality of second stiffening plates, and the plurality of third stiffening plates are each provided with a plurality of perforated holes. The design of the plurality of perforated holes helps to further reduce the weight of the tool magazine bracket and reduce costs.

[0011] Preferably, the first mounting plate has a plurality of first oblong holes, and the second mounting plate has a plurality of second oblong holes. The major axes of the plurality of first oblong holes and the plurality of second oblong holes are respectively horizontally arranged. The plurality of first oblong holes and the plurality of second oblong holes are used to install a plurality of fastening bolts. The first mounting plate is fixedly connected to the tool magazine by the plurality of fastening bolts, and the second mounting plate is fixedly connected to the crossbeam by the plurality of fastening bolts. The design of the plurality of first oblong holes and the plurality of second oblong holes can improve the assembly accuracy of the first mounting plate and the tool magazine, as well as the assembly accuracy of the second mounting plate and the crossbeam, thereby improving the installation accuracy of the tool magazine.

[0012] As a further preferred embodiment, a tool magazine mounting plate is fixed to one side of the crossbeam. A wedge block and a pull block are provided between the tool magazine mounting plate and the second mounting plate. The wedge block is used to adjust the vertical mounting position of the second mounting plate, and the pull block is used to adjust the front-rear mounting position of the second mounting plate. The wedge block and pull block can further improve the assembly accuracy between the second mounting plate and the crossbeam, improve the efficiency of on-site installation and debugging, and facilitate subsequent adjustment of the tool magazine tool changing position so that the tool magazine tool changing position coincides with the spindle tool changing position, thereby improving the machine tool assembly efficiency.

[0013] Compared with existing technologies, this utility model has the following advantages: The support body of the 45° follow-up tool magazine bracket applicable to moving-column gantry machining centers is welded from steel plates with a thickness of 16-25mm. While ensuring the overall rigidity, strength, and stability of the tool magazine bracket, its weight can be significantly reduced. This utility model's tool magazine bracket enables a 45° inclined installation of the tool magazine, which helps reduce the distance between the tool magazine cam rotating box and the tool disc, shortens the tool changer arm length, and correspondingly reduces the rotation radius of the tool changer arm. It also reduces the impact of the tool changer arm's own weight when it is extended, thus ensuring the stability of the tool magazine's tool changing action. Simultaneously, it saves space, making the overall machine tool structure more compact, and avoids water and chip accumulation in the tool magazine space. After adopting this utility model's tool magazine bracket, since the tool magazine can move with the crossbeam, tool changing can be performed directly within the machine tool's machining area, resulting in shorter tool changing times. Especially in machining scenarios requiring frequent tool changes, this significantly improves the machine tool's machining efficiency. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Components or structures not limited in this invention employ conventional techniques in the art.

[0025] The embodiment is applicable to the 45° follower tool magazine support of a moving column gantry machining center, such as Figure 1 and Figure 2As shown, the tool magazine bracket includes a frame-shaped bracket body welded from a 20mm thick Q235A steel plate. A first mounting plate 1 and a second mounting plate 2 are vertically welded to the outer edges of the bracket body, respectively. The first mounting plate 1 is welded to the front side of the bracket body in the length direction, and the second mounting plate 2 is welded to one side of the bracket body in the width direction. The included angle α between the orthographic projections of the first mounting plate 1 and the second mounting plate 2 on the horizontal plane is 45°. The front side of the first mounting plate 1 faces the front of the second mounting plate 2. The first mounting plate 1 is used for surface contact and fixed connection of the tool magazine 15 to achieve a 45° inclined installation of the tool magazine 15. The second mounting plate 2 is used for surface contact and fixed connection of one side of the crossbeam 14 of the moving column gantry machining center.

[0026] In this embodiment, a first support plate 3 and a second support plate 4 are horizontally welded to the upper and lower parts of the second mounting plate 2, respectively. A first vertical plate 5 and a second vertical plate 6 are welded to each other on the front side between the first support plate 3 and the second support plate 4. A third vertical plate 7 is welded to the front side of the second vertical plate 6 at a 45° angle. The two sides of the first mounting plate 1 are welded to the first vertical plate 5 and the third vertical plate 7, respectively. A plurality of first stiffening plates 8 are welded between the first support plate 3 and the second support plate 4. A plurality of second stiffening plates 9 are welded between the first vertical plate 5 and the second vertical plate 6. A plurality of third stiffening plates 10 are welded between the second vertical plate 6 and the first mounting plate 1. A plurality of hollow holes 11 are respectively opened on the first support plate 3, the second support plate 4, the first vertical plate 5, the second vertical plate 6, the plurality of first stiffening plates 8, the plurality of second stiffening plates 9, and the plurality of third stiffening plates 10.

[0027] In this embodiment, the first mounting plate 1 has a plurality of first waist-shaped holes 12, and the second mounting plate 2 has a plurality of second waist-shaped holes 13. The long axes of the plurality of first waist-shaped holes 12 and the plurality of second waist-shaped holes 13 are respectively arranged horizontally, and the plurality of first waist-shaped holes 12 and the plurality of second waist-shaped holes 13 are used to install a plurality of fastening bolts.

[0028] The support body of the aforementioned tool magazine bracket is welded from a 20mm thick steel plate and has a hollowed-out design. While ensuring the overall rigidity, strength and stability of the tool magazine bracket, the weight of the tool magazine bracket can be significantly reduced. Its overall weight is relatively light, approximately 155 kg.

[0029] After installation, as Figures 3-7As shown, the tool magazine bracket is directly fixed to one side of the crossbeam 14 of the moving column gantry machining center. A slide saddle 16 is installed on the linear guide along the Y-axis on the front side of the crossbeam 14, and a vertically movable slide ram 17 is installed on the slide saddle 16. The machine tool spindle is installed on the slide ram 17. The first mounting plate 1 is fixedly connected to the tool magazine 15 by several fastening bolts. A tool magazine mounting plate 18 is fixed to one side of the crossbeam 14, and a second mounting plate 2 is fixedly connected to the tool magazine mounting plate 18 by several fastening bolts. A wedge block 19 and a pull block 20 are provided between the tool magazine mounting plate 18 and the second mounting plate 2. The wedge block 19 is used to adjust the vertical installation position of the second mounting plate 2, and the pull block 20 is used to adjust the front and rear installation position of the second mounting plate 2.

[0030] When the crossbeam 14 moves, the tool magazine support can move synchronously with the tool magazine 15 along with the crossbeam 14. Compared with the traditional fixed tool magazine tool changing method, after the machine tool adopts this tool magazine support, since the tool magazine 15 can move with the crossbeam 14, tool changing can be performed directly in the machine tool's machining area. The tool changing time is short, which can greatly improve the machining efficiency of the machine tool, especially in machining scenarios that require frequent tool changes.

[0031] The aforementioned tool magazine bracket enables a 45° inclined installation of the tool magazine 15, reducing the distance between the tool magazine cam rotating box and the tool disc, thereby shortening the tool changer arm length and correspondingly reducing the rotation radius of the tool changer arm. It also reduces the impact of the tool changer arm's own weight when it is overhanging. This helps ensure the stability of the tool magazine's tool changing operation, saves space, makes the overall machine tool structure more compact, and prevents water and chip accumulation in the tool magazine space. The aforementioned tool magazine bracket occupies a width of 460mm during installation and use.

[0032] Without altering the main structure and dimensions of the tool magazine bracket, if a parallel tool magazine bracket is used—that is, a parallel tool magazine bracket with a 90° angle between the orthographic projections of the first mounting plate 1 and the second mounting plate 2 on the horizontal plane—a top view of this parallel tool magazine bracket after installation on the crossbeam is shown below. Figure 8 . Figure 8 In the diagram, a is the spindle center, b is the tool changer arm, c is the rotational coverage area of ​​the tool changer arm, and d and e are two different positions of the tool turret on the tool magazine. Compared to Figure 7 The tool magazine layout shown is designed to meet tool changing requirements. Figure 8 The tool changer arm needs to be designed with a longer length and a larger rotation radius, resulting in a larger rotation coverage area. Therefore, the tool turret position needs to be moved outward accordingly (from...). Figure 8 If position d is moved to position e), the width of the parallel tool magazine bracket needs to be increased to 942mm to complete the tool changing action. This design of the parallel tool magazine bracket is not conducive to saving space and will also affect the stability of the tool changing action.
