Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing equipment, and in particular to a bearing seat drilling and tapping device. Background Art

[0002] The bearing seat is an important component used to support the bearing in mechanical equipment. During the processing of the bearing seat, drilling and tapping operations are usually required. The drilling and tapping of the bearing seat need to be completed with the help of a drilling and tapping device. At present, the existing bearing seat drilling and tapping devices have some shortcomings as follows: On the one hand, drilling and tapping need to be performed separately on different machine tools, and the workpiece needs to be clamped and positioned multiple times, which not only increases clamping time but also easily causes clamping errors, resulting in reduced processing accuracy. On the other hand, the degree of automation of ordinary machine tools is low, requiring workers to operate frequently, making it difficult to further improve production efficiency. For example, when processing large batches of bearing seats, frequent clamping and operation will waste a lot of time and reduce production efficiency. In addition, although there are some automated drilling and tapping equipment on the market, these devices are often complex in structure, scattered, and expensive, resulting in poor versatility of the equipment.

[0022] Two first positioning rods 401 are provided on the lifting frame 302 for sliding in the vertical direction. A first positioning block 402 is connected between the bottoms of the two first positioning rods 401. The two first positioning rods 401 cooperate with each other to fix the first positioning block 402, so that the first positioning block 402 can move up and down in the lifting frame 302. A card slot is provided at the bottom position of the first positioning block 402, and the card slot has a V-shaped structure. A support spring is installed at the outer position of the first positioning rod 401, and the support spring presses the first positioning block 402 downward. A retaining spring is installed above the first positioning rod 401 to prevent the first positioning rod 401 from falling off the lifting frame 302.

The outer sides of the second rotating seats 504 are each sleeved with sprockets, and chains 505 are wound around the outer sides of the three sprockets. Therefore, when the first rotating seat 502 rotates, it can simultaneously drive the three second rotating seats 504 to rotate simultaneously. The second electric motor 501, the first rotating seat 502, the stabilizing rod 503, the second rotating seat 504, and the chain 505 cooperate with each other to form a drilling and tapping mechanism 5.

[0028] Example 2, based on Example 1, Figures 1-8As shown, a conveyor belt is installed on one side of the stabilizing frame 1. The coordination and assembly structure of the stabilizing frame 1 and the conveyor belt directly adopt the existing technology, so that the conveyor belt can automatically transport the bearing seat 8 to the processing, loading and unloading position.

[0029] The working principle of this embodiment is as follows: The operator uses bolts to assemble the stabilizing frame 1 and the positioning rail 2, and uses bolts to fix the first electric motor 301 on one side of the positioning rail 2 firmly, aligns the sliding block on one side of the lifting frame 302 with the dovetail sliding groove on the positioning rail 2, and meshes the driving gear on the driving shaft of the first electric motor 301 with the vertical rack on one side of the lifting frame 302. The two first positioning rods 401 are respectively inserted into the vertical sliding holes opened on both sides of the lifting frame 302, and the first positioning block 402 is installed at the bottom of the first positioning rod 401. When installing, pay attention to the direction and position of the slot on the first positioning block 402. Install a support spring and a retaining spring on the outside of the first positioning rod 401. The support spring should apply downward pressure to the first positioning block 402. Install the positioning plates 404 on both sides of the first positioning block 402 so that the positioning plates 404 are slidably connected to the sliding grooves on the first positioning block 402. Threaded rods 403 are threadedly connected to the threaded holes on the positioning plates 404. Rotatably install the first rotating seat 502 in the lifting frame 302. Install the second electric motor 501 on one side above the first positioning block 402. Connect the drive shaft of the second electric motor 501 to the top of the first rotating seat 502. The operator installs the stabilizing rod 503 into the mounting hole of the lifting frame 302 and fixes the stabilizing rod 503 to the lifting frame 302 with a locking bolt. A second rotating seat 504 is fixedly connected to the lower end of the first rotating seat 502. The lower ends of the two stabilizing rods 503 are rotatably connected to a second rotating seat 504. Sprockets are sleeved on the outer sides of the second rotating seats 504. Chains 505 are wound around the outer sides of the three sprockets. The tension of the chains 505 is adjusted. The third positioning rod 701 is inserted into the positioning sleeve at the bottom of the lifting frame 302. The second positioning block 702 is installed on one side of the third positioning rod 701. The bottom part of the second positioning block 702 is placed on the surface of the lifting frame 302. The operator adjusts the positioning mechanism 4 according to the model and size of the bearing seat 8 to be processed and rotates the threaded rod 403. Since the threaded rod 403 has a double-thread structure and is threadedly connected to the threaded hole on the positioning plate 404, the two positioning plates 404 can be controlled to move closer or farther away from each other, so that the distance between the two positioning plates 404 adapts to the size of the bearing seat 8; The operator transports the bearing seat 8 to be processed to the bottom position of the first positioning block 402, starts the first electric motor 301 to control the lifting frame 302 to move downward, and the first positioning block 402 and the positioning plate 404 move downward to position the bearing seat 8. The lifting frame 302 continues to move downward, and the drill bits at the bottom of the first rotating seat 502 and the second rotating seat 504 are aligned with the processing position of the bearing seat 8. The second electric motor 501 is controlled to drive the drill bit to rotate, and the drill bit drills and taps the bearing seat 8. After the drilling and tapping of the bearing seat 8 are completed, the first electric motor 301 is controlled to lift the lifting frame 302. At this time, the drill bit, the first positioning block 402, and the positioning plate 404 leave the bearing seat 8, and the next bearing seat 8 is switched to repeat the above steps to continue processing.
