Description

Technical Field

[0001] The present invention relates to the technical field of numerical control processing equipment, and in particular to a crane bearing seat processing crane pulley block drilling and tapping integrated machine. Background Art

[0002] A drilling and tapping machine is a CNC machine that combines drilling and tapping functions, primarily used in the metalworking industry. By combining the two processes, it significantly improves production efficiency and machining accuracy. Drilling and tapping machines are commonly used to process holes in various metal materials, such as steel, aluminum, and copper, and are widely used in industries such as automotive, aviation, and mold manufacturing.

[0003] The prior art document with publication number CN110434611A provides a drilling and tapping machine, which solves the problem of manually taking the workpiece into the tapping machine for tapping, and at the same time filters the coolant in the machine body.

[0004] Existing technology uses flat fixing blocks (1 and 2) to clamp and secure the bearing seat during drilling and tapping. However, this flat fixing method is difficult to adapt to the special shape of the angle box bearing seat used in crane machining. Poor adaptability can lead to numerous problems. Firstly, unstable clamping can easily cause displacement of the angle box bearing seat during machining, seriously affecting machining accuracy. Secondly, in extreme cases, the angle box bearing seat may not be securely fixed, which not only reduces machining quality but also poses safety risks. For example, under the action of the high-speed rotating tool, loose workpieces may fly out, endangering the operator's personal safety.

[0035] like Figure 6As shown, both ends of the flip seat 7 are fixedly connected with a rotating shaft 701, and the rotating shaft 701 is rotatably connected to the movable seat 5. One end of the rotating shaft 701 is fixedly connected with a worm gear 702, and the worm gear 702 is meshed with the worm 502 for transmission. A fan gear 703 is fixedly connected to one of the rotating shafts 701, and the fan gear 703 is meshed with the adjusting wheel 608 for transmission. An angle box bearing seat 704 is placed on the flip seat 7, and a stop block 705 is fixedly connected to the flip seat 7, and one side of the stop block 705 is adapted to one side of the angle box bearing seat 704.

[0036] like Figure 7 As shown, the push-pull mechanism 8 includes a bidirectional screw rod 801, which is rotatably connected to the inner wall of the flip seat 7. One end of the bidirectional screw rod 801 passes through the inner wall of the flip seat 7 and extends to the outside and is fixedly connected with a transmission wheel A802. The transmission wheel A802 is meshed with the fixed rack A301 for transmission. The outer walls of both ends of the bidirectional screw rod 801 are threadedly connected with adjustment blocks 803. The adjustment block 803 is rotatably connected with a push-pull rod 804, and the other end of the push-pull rod 804 is rotatably connected to the limit plate 9.

[0037] like Figure 8 As shown, one side of the limit plate 9 is adapted to fit over the outer wall of the corner box bearing seat 704. Two electric push rods 901 are symmetrically connected at both ends of the limit plate 9 for rotational connection. A vertical pressure rod 902 is fixedly connected to the top of each electric push rod 901. The outer wall of the vertical pressure rod 902 is in sliding contact with the corner box bearing seat 704. A gear 903 is fixedly connected to the bottom of the electric push rod 901. The electric push rod 901 can adjust the height of the vertical pressure rod 902 to accommodate corner box bearing seats 704 of varying thickness.

[0038] A U-shaped rack 904 is slidably mounted on the inner wall of the limit plate 9. Both ends of the U-shaped rack 904 mesh with gear 903 for transmission. Multiple springs 905 are fixedly connected between one side of the U-shaped rack 904 and the inner wall of the limit plate 9. A contact rod 906 is fixedly mounted on the other side of the U-shaped rack 904. One end of the contact rod 906 extends through the inner wall of the limit plate 9 to the outside and is in movable contact with the corner box bearing seat 704. The spring 905 automatically resets the U-shaped rack 904.

[0039] By setting a stop block 705 and a limit plate 9 that are compatible with the shape of the angle box bearing seat 704, smooth and uniform clamping is ensured, the problem of incompatibility of traditional planar fixing blocks is avoided, and the clamping accuracy and stability are improved. At the same time, a rotatable and height-adjustable vertical pressure rod 902 is set on the limit plate 9. When the stop block 705 and the limit plate 9 clamp the angle box bearing seat 704 horizontally, the vertical pressure rod 902 is pressed against the upper side of the angle box bearing seat 704, and multi-directional fixation is achieved through multi-point clamping, ensuring the stability of the workpiece during processing and reducing vibration or offset.

[0040] Working principle: When drilling and tapping the angle box bearing seat 704 in the crane, the angle box bearing seat 704 is first placed on the turning seat 7. Then, the motor 402 drives the lead screw 401 to rotate, so that the lead screw 401 drives the movable seat 5 connected to the slide 501 to move downwards from the drilling equipment.

[0041] At this time, under the action of the fixed rack A301, the transmission wheel A802 engaged with it drives the connected bidirectional screw 801 to rotate, so that the bidirectional screw 801 can drive the two adjustment blocks 803 to separate and move, thereby driving the limit plate 9 to approach the angle box bearing seat 704 through the push-pull rod 804, and cooperating with the stop block 705 to clamp and fix the angle box bearing seat 704;

[0042] At the same time, when the limit plate 9 is close to the angle box bearing seat 704, the contact rod 906 will contact the angle box bearing seat 704, and move inward toward the limit plate 9 under the action of the angle box bearing seat 704, thereby driving the connected U-shaped rack 904 to move, so that the U-shaped rack 904 drives the meshing gear 903 to rotate, so that the gear 903 drives the vertical pressure rod 902 connected to the electric push rod 901 to rotate to the top of the angle box bearing seat 704, thereby limiting it vertically, and preventing the drilling drill bit and the tapping drill bit from driving the angle box bearing seat 704 to move when moving upward;

[0043] Then the clamped angle box bearing seat 704 is moved to the bottom of the drilling bit for drilling. After the drilling is completed, the angle box bearing seat 704 is continued to be moved to the bottom of the tapping bit for tapping.

[0044] After the tapping is completed, the angle box bearing seat 704 is driven to move to the right. At this time, when the transmission wheel B503 is engaged with the fixed rack B302, the worm 502 is driven to rotate, so that the worm 502 drives the rotating shaft 701 connected to the worm wheel 702 to rotate, thereby driving the flip seat 7 to flip 180 degrees, so that the drill hole of the angle box bearing seat 704 faces downward;

[0045] At the same time, when the flip seat 7 is about to flip into place, the fan gear 703 on its rotating shaft 701 will drive the adjusting wheel 608 to rotate, so that the adjusting wheel 608 drives the push rod 606 connected to the universal joint 607 to rotate, so that the push rod 606 can lift the movable plate 603, so that the top of the telescopic jet pipe 604 connected to the movable plate 603 is close to the drill hole of the angle box bearing seat 704, and then the air pump 602 injects high-pressure gas into the telescopic jet pipe 604 through the air guide seat 601, and sprays it into the drill hole of the angle box bearing seat 704 through the telescopic jet pipe 604, so that the drill chips inside are cleaned;

[0046] After cleaning, drive the corner box bearing seat 704 to move to the left and reset. At this time, the fixed rack A301 will cause the push-pull mechanism 8 to automatically drive the limit plate 9 to move away, releasing the limit of the diagonal box bearing seat 704, making it easy to remove.
