Description

Technical Field

[0001] The present application relates to the technical field of vertical machining centers, and particularly relates to an auxiliary positioning tooling for a vertical machining center. Background Art

[0002] A vertical machining center refers to a machining center in which the spindle axis is vertically arranged with respect to the workbench, and is mainly applicable to machining complex parts such as plate-like, disc-like, molds, and small shell-like parts. A vertical machining center can complete processes such as milling, boring, drilling, tapping, and cutting threads.

[0003] A Chinese patent with the publication number CN220944239U discloses an auxiliary positioning tooling for a vertical machining center. The auxiliary positioning tooling for a vertical machining center includes an operating table. A center frame is arranged inside the operating table, and a component is placed inside the center frame. A positioning mechanism for fixing the position of the component is arranged on the surface of the center frame. A rotating mechanism for flipping the position of the component is arranged inside the operating table. The rotating mechanism includes an inner groove, which is opened on the inner wall of the operating table, and a connecting plate is inserted into the inner groove. By setting the rotating mechanism in the present utility model, when it is necessary to flip the component, the connecting plate is driven to move by rotating the bolt, so that the U-shaped plate can be disengaged from the outside of the component, thereby releasing the restriction on the position of the center frame. Then, the rotating shaft fixedly installed on the outside of the center frame can rotate inside the operating table, so that the operator can perform a 180-degree rotation and pushing operation on the component. This structure is simple to operate and time-saving and labor-saving.

[0004] However, the above-mentioned auxiliary positioning device has the following disadvantages: By setting the rotating mechanism, the component can be flipped, but the length of the bottom plate of the device cannot be adjusted, so that the center frame can only place components of the same size and cannot place components of different sizes for positioning, resulting in a significant reduction in the versatility of the device and low stability.

A locking mechanism is arranged on the side of the support frame 6 away from the limiting block 5. On the side of multiple support frames 6 close to the center support 1, there are positioning mechanisms 3; By setting the movable bottom plate 2, the driving mechanism drives the slider 9 to move towards one side of the center support 1, and the slider 9 drives the bottom plate 2 to move towards the middle of the center support 1, so that parts of different sizes can be placed inside the center support 1, greatly improving the versatility and stability of the equipment. By setting the sliding plate 4 and the limiting block 5, the positioning mechanism 3 can be adjusted to move inside the center support 1, so as to position parts of different sizes. By setting the scraping plate 12 and the collection box 13, the dust and debris left by the machining of the parts on the bottom plate 2 can be cleaned up.

[0024] Refer to Figure 5 , On both sides of the inner part of the center support 1 near the bottom plate 2, scraping plates 12 are slidably installed. There is a certain resistance between the scraping plate 12 and the center support 1, and the movement of the bottom plate 2 will not drive the scraping plate 12 to shift in position. The bottom of the scraping plate 12 is in contact with the top of the bottom plate 2, which can scrape the dust and debris above the bottom plate 2 outside the sliding groove while the bottom plate 2 moves.

[0025] Refer to Figure 5 , On the side of both bottom plates 2 away from the center support 1, there are collection boxes 13. Two cross-shaped card slots 15 are penetrated and opened on the side of the bottom plate 2 close to the collection box 13. Two cross-shaped card blocks 14 are fixedly installed on the side of the two collection boxes 13 close to the bottom plate 2. The cross-shaped card blocks 14 are adapted to the cross-shaped card slots 15, and the collection box 13 can be fixed on one side of the bottom plate 2, so as to collect the dust and debris of the bottom plate 2 in the collection box 13.

[0026] Refer to Figures 2-4The driving mechanism includes a screw rod 8, a first bevel gear 10, a second bevel gear 11 and a motor 7. The screw rod 8 is rotatably installed in the slide groove, the screw rod 8 passes through the slider 9, the screw rod 8 is threadedly connected to the slider 9, one end of the screw rod 8 is fixedly installed with the second bevel gear 11, a first bevel gear 10 is provided on one side of the second bevel gear 11, the first bevel gear 10 is meshed with the second bevel gear 11, an L-shaped groove is provided on one side of the slide groove, the first bevel gear 10 and the second bevel gear 11 are located in the L-shaped groove, a motor 7 is fixedly installed on one side of the L-shaped groove, the output end of the motor 7 is transmission connected with the first bevel gear 10, and the base plate 2 can be moved to the middle of the center frame 1, so that parts of different sizes can be placed on the base plate 2.

[0027] Reference Figure 6 The locking mechanism includes a bolt 17 and a knob 18. Bolts 17 are provided on both sides of the support frame 6. The bolt 17 passes through one side of the support frame 6. The bolt 17 is threadedly connected to the support frame 6. One end of the bolt 17 is in contact with the limit block 5. The end of the bolt 17 away from the limit block 5 is fixedly installed with a knob 18, which can lock the slide plate 4 to prevent the positioning mechanism 3 from shifting.

[0028] The implementation principle of the auxiliary positioning tooling of a vertical machining center in the embodiment of the present application is as follows: when in use, according to the size of the parts, the motor 7 is started, the motor 7 drives the first bevel gear 10 to rotate, the first bevel gear 10 drives the second bevel gear 11 to rotate, the second bevel gear 11 drives the screw 8 to rotate, the screw 8 drives the slide block 9 to move to one side of the center frame 1, the slide block 9 drives the bottom plate 2 to move to the middle of the center frame 1, so that parts of different sizes can be placed inside the center frame 1, and then according to the size of the parts, the knob 18 is turned, the knob 18 drives the bolt 17 to rotate outward to release the lock of the limit block 5, and then the slide plate 4 is slid forward, the limit block 5 under the slide plate 4 slides in the limit groove 16, so that multiple slide plates 4 all move into the center frame 1, Approach the parts, then adjust the positioning mechanism 3 downward to position the parts, and then process the parts. The debris or dust generated during the processing may be left on the bottom plate 2. After the parts are taken away, the driving mechanism drives the slider 9 and the bottom plate 2 to move toward the inside of the center frame 1. While the bottom plate 2 moves, it drives the scraper 12 on the side of the center frame 1 to scrape the debris and dust on the bottom plate 2 outward, thereby preventing the dust from entering the center frame 1. Then the scraper 12 can be manually slid to scrape the remaining debris and dust on the outside of the bottom plate 2 into the collection box 13. After the collection box 13 is full, the collection box 13 can be slid so that the cross block 14 slides upward out of the cross slot 15, and the debris and dust in the collection box 13 are processed, and then it is installed back to continue collecting.
