[0031] In a specific embodiment, the alignment and flipping device for a gantry milling boom provided by the present invention includes a headstock 1, a translation support 2, and a rotary tailstock 4.

[0032] Among them, the headstock 1 includes a headstock body installed on the gantry milling machine worktable 5 and a chuck 6 for detachably and fixedly connecting to one end of the boom 3. The chuck 6 is rotatably connected to the headstock body around the longitudinal direction. The gantry milling machine worktable 5 is the worktable for gantry milling machining, and the alignment and flipping device provided in this application is installed on the gantry milling machine worktable 5. The headstock 1 includes a headstock body and a chuck 6, and the chuck 6 is rotatably connected to the headstock body. The rotation axis is along the longitudinal direction, that is, the chuck 6 can rotate relative to the headstock body around the longitudinal direction to facilitate the flipping of the boom 3. The detachable and fixed connection between the chuck 6 and the boom 3 can specifically be snap connection, bolt connection, etc., which is not specifically limited here.

[0033] The translation support 2 includes a support body installed on the gantry milling machine table 5 and capable of sliding relative to the gantry milling machine table 5 in the transverse direction, and a lifting mechanism 9 fixed to the support body for supporting the boom 3. That is, the translation support 2 includes a support body and a lifting mechanism 9. The support body can move transversely, and the lifting mechanism 9 is fixed to the support body and can move up and down in the vertical direction. It should be noted that the transverse direction mentioned here and below refers to the transverse direction of the boom 3 in the installation state of the boom 3, and the longitudinal direction is perpendicular to the transverse direction and is the extending direction of the boom 3. The translation support 2 is used to cooperate with the rotary tailstock 4 to support the boom 3.

[0034] The rotary tailstock 4 includes a base 12 installed on the gantry milling machine table 5 and a support frame rotatably connected to the base 12 about the vertical direction. A rotary disk 11 is rotatably connected to the support frame about the longitudinal direction. The rotary disk 11 is used for detachably and fixedly connecting to the other end of the boom 3. That is, the rotary tailstock 4 includes a base 12, a support frame, and a rotary disk 11. The support frame is rotatably connected to the base 12, and the rotation axis is along the vertical direction. That is, the support frame can rotate relative to the base 12 about the vertical direction to facilitate alignment with the translation support 2 for the boom 3. The rotary disk 11 is also rotatably connected to the support frame, and the rotation axis is along the longitudinal direction. Then the rotary disk 11 can rotate relative to the support frame about the longitudinal direction to facilitate flipping of the boom 3. Specifically, the rotary disk 11 can rotate and roll 360° relative to the support frame, and can drive the boom 3 to complete flipping. The rotary connection can be specifically realized through bearings, etc. The bottom end of the base 12 can be fixedly connected to an installation base and fixedly connected to the gantry milling machine table 5 through bolts. Specifically, the support frame can rotate 360° relative to the base 12 to drive the boom 3 to swing in the horizontal direction.

[0035] When applying the alignment and flipping device for the gantry milling boom 3 provided by the present invention, first, the boom 3 is installed in the translation support 2 and the rotary disk 11. When aligning the boom 3, the rotary disk 11 on the rotary tailstock 4 provides preliminary horizontal positioning for the boom 3, and the lifting mechanism 9 on the translation support 2 is finely adjusted to make the boom 3 horizontal; the support body of the translation support 2 is adjusted to move transversely along the gantry milling machine table 5 to make the boom 3 parallel to the longitudinal direction of the table, thereby completing the alignment of the boom 3. When flipping the boom 3, the chuck 6 on the headstock 1 is connected to the head of the boom 3 to clamp the boom 3, and then by pushing the boom 3, it is flipped under the rotation of the chuck 6 and the rotation of the rotary disk 11. In summary, the alignment and flipping device for the gantry milling boom 3 provided by the present invention adopts a split-functional-block structure design. Each functional block can be used separately or in combination, can realize the alignment and flipping of the boom 3, shortens the machine tool occupation time during the alignment and turning over of boom 3 - type workpieces in the machining process, improves safety, reduces labor intensity, improves production efficiency, reduces production cost, and improves the production benefit of products.

[0036] Specifically, the rotary disk 11 includes a split first disk and a second disk, and the first disk and the second disk cooperate to form a support hole having the same shape as the boom 3 and for the boom 3 to pass through. The split structure design facilitates the installation of the boom 3. By setting the support hole to have the same shape as the boom 3, it is convenient to support the boom 3 through the rotary disk 11 and provide preliminary horizontal positioning for the boom 3, and then cooperate with the lifting mechanism 9 on the fine-tuning translation support 2 to level the boom 3. Specifically, the first disk and the second disk are detachably fixedly connected to facilitate the installation of the boom 3. Preferably, the connection position of the first disk and the second disk is adjustable so that the size of the formed support hole is adjustable, thereby being applicable to booms 3 of different specifications.

[0037] Furthermore, a positioning device is provided on the rotary tailstock 4 for locking the position of the rotary disk 11 at the horizontal level corresponding to the boom 3. That is, through the setting of the positioning device, the position of the rotary disk 11 can be locked at the horizontal position corresponding to the boom 3, thereby providing preliminary horizontal positioning for the boom 3. When the boom 3 is flipped, the positioning function of the positioning device on the rotary disk 11 can be cancelled. Specifically, pin holes can be respectively provided on the support frame and the rotary disk 11, and the positioning of the two can be achieved by inserting pins, such as positioning by special-shaped pins or positioning by at least two pins and corresponding pin holes. According to needs, the positioning device can also adopt other positioning structures such as buckles. The above illustrates the preliminary horizontal positioning through the rotary disk 11. According to needs, multiple lifting mechanisms 9 can also be provided, and the horizontal positioning of the boom 3 can be achieved through the cooperation of the multiple lifting mechanisms 9.

[0038] In one embodiment, an anti-tipping block 8 is detachably fixedly connected to the support body. The anti-tipping block 8 includes columns for limiting the lateral ends of the boom 3. The anti-tipping block 8 can prevent the boom 3 from tipping during alignment. Specifically, the distance between the opposite two columns of the anti-tipping block 8 is adjustable. On the one hand, it facilitates the installation of the boom 3, and on the other hand, it is convenient to adapt to different booms 3. The specific adjustment method of the column distance can be achieved by setting multiple bolt holes and fixedly connecting the columns to different bolt holes, or by means of thread fitting. The anti-tipping block 8 is detachably fixedly connected to the support body. When the boom 3 is flipped, the anti-tipping block 8 is first removed to prevent it from restricting the flipping of the boom 3.

[0039] Further, the translation support 2 includes a support guide rail 10 fixedly connected to the gantry milling machine workbench 5. The support guide rail 10 extends horizontally, and the support body is slidably mounted on the support guide rail 10. That is, through the cooperation of the support guide rail 10 and the support body, the horizontal movement of the support body is realized. The setting of the support guide rail 10 can play a guiding and limiting role in the movement of the support body. Specifically, the bottom of the support guide rail 10 can be fixedly connected to the mounting base 12, and the mounting base 12 can be fixedly connected to the gantry milling machine workbench 5 by bolts. Specifically, a threaded portion can be provided on the support body, and a lead screw is provided in cooperation with the threaded portion. By rotating the lead screw, the support body is driven to reciprocate along the support guide rail 10. To facilitate the rotation of the lead screw, a rotation handle is fixedly provided coaxially with the lead screw. According to needs, a horizontal driving device is provided in cooperation with the support body to drive the support body to move along the support guide rail 10. Specifically, the horizontal driving device can adopt driving forms such as hydraulic, electric or pneumatic to realize the automatic fine adjustment of the boom 3 in the horizontal direction.

[0040] Specifically, the lifting mechanism 9 is a lifting center point, which can not only reliably support the boom 3, but also conveniently adjust the height of the boom 3 to make the boom 3 horizontal. According to needs, the lifting mechanism 9 can also adopt other lifting structures such as hydraulic or pneumatic.

[0041] In one embodiment, the headstock body is slidably connected to the gantry milling machine workbench 5 longitudinally. That is, the headstock 1 is a movable headstock. By setting the headstock body to be longitudinally slidable, the installation of boom 3 with different lengths can be satisfied. Specifically, when the boom 3 is flipped, the longitudinal movement of the headstock body is adjusted to connect with the head of the boom 3, and the chuck 6 clamps the boom 3 and drives the boom 3 to complete the flipping.

[0042] Specifically, the headstock 1 includes a sliding guide rail 7 fixedly connected to the gantry milling machine workbench 5. The sliding guide rail 7 extends longitudinally, and the headstock body is slidably mounted on the sliding guide rail 7. That is, through the cooperation of the sliding guide rail 7 and the headstock body, the longitudinal movement of the headstock body is realized to adjust the distance between the headstock body and the boom 3. The setting of the sliding guide rail 7 can play a guiding and limiting role in the movement of the headstock body.

[0043] Further, a plurality of chucks 6 are provided in cooperation with the headstock body, and each chuck 6 is respectively used to fix the boom 3 with different structures. The headstock body is equipped with different forms of chucks 6, which are applicable to boom 3 of various structural forms, thereby making the applicable range of the alignment and flipping device wider. And because the chucks 6 are all detachably fixedly connected to the headstock body, the replacement of different chucks 6 can be conveniently carried out.

[0044] Based on the above embodiments, it further includes a driving mechanism for driving the chuck 6 and the rotary disk 11 to rotate so as to drive the boom 3 to turn over. The driving mechanism can specifically adopt driving forms such as hydraulic, electric or pneumatic, and automatic turning can be realized by driving of the driving mechanism. If necessary, the driving mechanism may not be provided, and the boom 3 can be manually pushed to rotate. Due to the supporting effect of the chuck 6 and the rotary disk 11, the operation difficulty of manual pushing is reduced.

[0045] The alignment and turning using the above alignment and turning device generally include the following steps:

[0046] Step 1: Install each component of the device on the gantry milling machine workbench 5 according to the assembly sequence;

[0047] Step 2: Install the boom 3 into the translation support 2 and the rotary disk 11 and lock the rotary disk 11. Specifically, bolts can be used for locking, and there is still a tiny moving space;

[0048] Step 3: Fine-tune the lifting mechanism 9 on the translation support 2 to make the boom 3 horizontal;

[0049] Step 4: Adjust the support body to move along the support guide rail 10, drive the boom 3 and make it longitudinally parallel to the workbench, complete the alignment of the boom 3, and then fasten the boom 3 to the workbench and process it. Specifically, the boom 3 and the gantry milling machine workbench 5 can be fastened through traditional auxiliary fixing components;

[0050] Step 5: After the processing is completed, move the headstock body of the headstock 1 to a suitable position according to the length of the boom 3, and fix the boom 3 with a suitable chuck 6 according to the structure of the boom 3;

[0051] Step 6: Remove the anti-tipping block 8 on the translation support 2, release the locking of the rotary disk 11, and push the boom 3 to complete the turning; repeat steps three to four to complete the processing of the boom 3.

[0052] In summary, the alignment and turning device provided by this application adopts a split-functional block structure design. Each functional block can be used separately or in combination, and can realize the alignment and turning of booms 3 with different sizes and different structural forms, effectively solving the problems of long machine tool occupation time, low safety, and high labor intensity in the alignment and turning of boom 3 type workpieces during the machining process, and improving the production efficiency of products.
