Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment, and specifically relates to a drilling device for the production of differential housings. Background Art

[0002] The differential is a key component in the automotive transmission system. Its main function is to enable the left and right wheels to rotate at different speeds when the vehicle turns or travels on an uneven road surface, thereby ensuring the smooth control and driving of the vehicle. During the production of the differential, in order to install bolts subsequently and achieve precise fitting of shaft parts, etc., it is necessary to use a drilling device to drill the differential housing.

[0003] However, during the processing of the differential housing by a drilling and tapping machine, in order to improve the processing efficiency, the turntable needs to rotate at a relatively high speed to reach the processing station during rotation. The cutting fluid sprayed on the turntable during processing will generate a large centrifugal force due to the high-speed rotation of the turntable, resulting in an overly large splash range of the cutting fluid. This not only makes the working environment dirty and messy, increasing the cleaning difficulty and time; at the same time, when the drilling and tapping machine needs to replace the mold according to different models of differentials, since multiple molds are fixedly installed on the turntable through multiple bolts, a large number of bolts need to be disassembled and installed sequentially during the replacement process, the operation is cumbersome and time-consuming, thus affecting the replacement efficiency and processing efficiency; the drilling and tapping machine filters and separates the cutting fluid and waste chips through a filter screen to achieve the reuse of the cutting fluid. However, in actual production, the waste chips generated during processing will continuously fall onto the filter screen. Over time, a large amount of waste chips are likely to block the pores of the filter screen, hindering the normal filtration and circulation of the cutting fluid, resulting in a significant decrease in the filtration efficiency and affecting the stability of the drilling and tapping machine.

[0037] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 and Figure 10As shown, a guide sleeve 310 is fixedly connected to the drilling and tapping machine body 1. The mounting rod 309 is slidably connected to the guide sleeve 310. The guide sleeve 310 plays a guiding role to ensure the smooth and stable sliding process of the mounting rod 309. A slide plate 205 is slidably connected to the adjusting plate 203. A pneumatic finger 207 is installed on the slide plate 205. A slider 208 is slidably connected to the pneumatic finger 207.

A torsion spring 213 is fixedly connected between the mounting shaft 212 and the mounting block 209. A stop rod 214 is fixedly connected to the mounting shaft 212. By rotating the stop rod 214, the stop rod 214 drives the mounting shaft 212 to rotate, and the rotation of the mounting shaft 212 deforms the torsion spring 213. When the stop rod 214 no longer blocks the connecting block 210, the connecting block 210 can be detached from the mounting block 209, which is convenient for quickly replacing clamping blocks 211 of different specifications to make the clamping effect better. A first driving member 206 is installed on the adjusting plate 203. The slide plate 205 is driven by the first driving member 206.

[0038] Specifically, such as Figure 1 , Figure 4 , Figure 11 and Figure 12As shown, the diversion structure 4 includes four fixing plates 401 fixedly connected to the drilling and tapping machine body 1 and a water shield 402 slidably connected to the fixing plates 401. The setting of the water shield 402 effectively reduces the splashing range of the cutting fluid. The reduction of the splashing range of the cutting fluid makes the environment around the drilling and tapping machine body 1 cleaner and more orderly, reduces the adhesion and accumulation of the cutting fluid on the table of the drilling and tapping machine body 1 and the workshop floor, not only improves the working environment, but also reduces the time for subsequent cleaning work and improves the working efficiency of the drilling and tapping machine body 1. A through groove 403 is provided on the drilling and tapping machine body 1. A sliding sleeve 404 is fixedly connected to the water shield 402. The sliding sleeve 404 is slidably connected to the fixing plate 401. A limiting block 405 is slidably connected to one of the sliding sleeves 404. Two limiting holes 406 are provided on one of the fixing plates 401. The limiting block 405 is engaged with one of the limiting holes 406.

A turntable 604 is fixedly connected to the transmission shaft 602. An installation ring 605 is detachably connected to the turntable 604. A mold 606 is fixedly connected to the installation ring 605. Through the design of installing multiple molds 606 on one installation ring 605, rapid switching can be achieved when the mold 606 is replaced, greatly improving the replacement efficiency and thus enhancing the overall processing efficiency of the drilling and tapping machine body 1. A positioning block 607 is fixedly connected to the installation ring 605. The positioning block 607 is slidably connected to the turntable 604. A second driving member 603 is installed on the mounting seat 601. The transmission shaft 602 is driven by the second driving member 603.

[0039] Specifically, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the mounting structure 7 includes two mounting plates 701 slidably connected to the turntable 604 and a drive shaft 702 rotatably connected to the mounting plates 701. A connecting plate 704 is rotatably connected to the turntable 604. A cam groove 703 is provided on the connecting plate 704. The drive shaft 702 is in rolling cooperation with the cam groove 703. A drive column 705 is fixedly connected to the connecting plate 704. The drive column 705 is rotatably connected to the turntable 604. During the rotation of the drive column 705, it can simultaneously drive the two mounting plates 701 to engage with the two positioning blocks 607, realizing the quick fixation of the mounting ring 605 on the turntable 604, further improving the mounting efficiency, and ensuring that the equipment can be efficiently and stably put into subsequent processing. A slide bar 706 is slidably connected to the drive column 705. Two limit columns 707 are fixedly connected to the slide bar 706. A connecting column 708 is fixedly connected to the turntable 604. The drive column 705 is rotatably connected to the connecting column 708. Four jacks 709 are provided on the connecting column 708. The two limit columns 707 are respectively engaged with the two jacks 709. By the engagement of the limit columns 707 and the connecting column 708, the fixation of the rotated connecting plate 704 is realized, improving its stability. A connecting rod 710 is fixedly connected to the slide bar 706. The connecting rod 710 is slidably connected to the drive column 705. A pressing block 711 is fixedly connected to the connecting rod 710. The pressing block 711 is slidably connected to the drive column 705. A second spring 712 is fixedly connected between the pressing block 711 and the drive column 705.

[0040] When the present invention is in use, when the device needs to be loaded, the differential housing is transported to the loading block at the bottom of the pneumatic finger 207 by a conveying device. Then, the first driving member 206 (the first driving member 206 is preferably a hydraulic rod) is started. The telescopic end of the hydraulic rod extends to drive the slide plate 205 to move downward. The slide plate 205 further drives the pneumatic finger 207 to move downward. When it moves to the set position, the pneumatic finger 207 starts to work, driving the two sliders 208 to slide towards each other. The sliders 208 will slide to drive the mounting block 209, the connecting block 210 and the clamping block 211 to move synchronously, so that the two clamping blocks 211 clamp the differential housing. After clamping, the telescopic end of the hydraulic rod contracts to drive the slide plate 205 to move upward a certain distance. Subsequently, the linear module 202 is started. The slide table of the linear module 202 drives the adjusting plate 203 to move. When the adjusting plate 203 moves, the connecting shaft 204 on the adjusting plate 203 rolls and cooperates in the driving groove 312 of the driving rod 311, causing the driving rod 311 to perform a reciprocating up-and-down movement. The driving rod 311 drives the mounting rod 309 to move up and down. The mounting rod 309 slides and cooperates with the guide sleeve 310. The guide sleeve 310 plays a guiding role to ensure that the sliding process of the mounting rod 309 is stable and smooth. At the same time, the mounting rod 309 drives the rack 306 to perform a reciprocating up-and-down movement through the fixing rod 308. The rack 306 slides and cooperates with the guide rail 307. The guide rail 307 ensures the stability and accuracy of the sliding of the rack 306. When the rack 306 slides, it drives the gear 305 to rotate. The gear 305 drives the rotating shaft 303 to rotate, and further rotates the stirring rod 304 on the rotating shaft 303. During the rotation of the stirring rod 304, it can stir the waste chips on the filter screen 302, preventing the waste chips from accumulating on the surface of the filter screen 302 to form a dense layer, ensuring that the cutting fluid can smoothly pass through the filter screen 302 for filtration, thereby ensuring the normal operation of the filter screen 302 and guaranteeing the working continuity of the drilling and tapping machine body 1. When the differential housing is transported above the mold 606, it is placed on the mold 606, and then the differential housing can be processed. If it is necessary to replace the clamping block 211 according to different sizes of the differential housing, the stop rod 214 can be rotated. The stop rod 214 drives the mounting shaft 212 to rotate. The rotation of the mounting shaft 212 deforms the torsion spring 213. When the stop rod 214 no longer blocks the connecting block 210, the connecting block 210 can be detached from the mounting block 209, which is convenient for quickly replacing different specifications of the clamping block 211 to make the clamping effect better;

[0041] When drilling the differential housing, first start the second driving member 603 (the second driving member 603 is preferably a motor). The rotation of the output shaft of the motor drives the transmission shaft 602 to rotate, and the transmission shaft 602 further drives the turntable 604 to rotate. The turntable 604 drives the differential housing to move through the mounting ring 605 and the mold 606. When the differential housing moves below the drilling device 9, start the third driving member 8 on the mounting frame 5 (the third driving member 8 is preferably a hydraulic rod). The telescopic end of the hydraulic rod is equipped with a drilling device 9, and the internal transmission component drives the drilling bit to rotate at high speed to drill the differential housing. After the drilling process is completed, the turntable 604 continues to rotate, transporting the differential housing to the bottom of the tapping device 10. The transmission component in the tapping device 10 drives the tapping bit to rotate, and in cooperation with the hydraulic rod, continues to perform tapping on the differential housing. According to the processing requirements, the turntable 604 can continue to rotate to send the differential housing to the subsequent chamfering processing station to complete the chamfering processing. During the rotation of the turntable 604, the setting of the water shield 402 effectively reduces the splashing range of the cutting fluid. The reduction of the splashing range of the cutting fluid makes the environment around the drilling and tapping machine body 1 cleaner and more orderly, reducing the adhesion and accumulation of the cutting fluid on the table surface of the drilling and tapping machine body 1 and the workshop floor. This not only improves the working environment but also reduces the time for subsequent cleaning work, improving the working efficiency of the drilling and tapping machine body 1. The splashed cutting fluid flows through the through groove 403 to the filter screen 302, realizing the filtering and separation of waste chips and cutting fluid. When it is necessary to replace different molds 606, pull the pull rod 408 to drive the limit block 405 to move. During this process, the first spring 407 contracts, and the limit block 405 disengages from the engagement state with the limit hole 406. After the limit block 405 no longer engages with the limit hole 406, the water shield 402 slides down a certain distance along the fixed plate 401 through the sliding sleeve 404, providing sufficient operating space for the operator to replace the mold 606;

[0042] When it is necessary to replace the mold 606, use an Allen wrench to press the pressing block 711. The pressing block 711 moves downward, causing the second spring 712 to contract. At the same time, the pressing block 711 drives the connecting rod 710 to move, and the connecting rod 710 drives the sliding rod 706 to move, so that the limiting column 707 on the sliding rod 706 is no longer engaged with the jack 709. At this time, use the Allen wrench to drive the driving column 705 to rotate 90 degrees. The driving column 705 drives the connecting disk 704 to rotate. During the rotation of the connecting disk 704, the driving shaft 702 rolls and fits in the cam groove 703, so that the two driving shafts 702 drive the two mounting plates 701 to slide towards each other, and the mounting plates 701 are no longer engaged with the positioning blocks 607. Then, pull out the Allen wrench, and the limiting column 707 will re-engage with the jack 709 under the action of the second spring 712. Through the engagement of the limiting column 707 and the connecting column 708, the fixed connection disk 704 after rotation is fixed, improving its stability. After completion of the fixation, the mounting ring 605 and the positioning block 607 can be detached from the turntable 604 to perform the replacement operation of the mold 606. Through the design of installing multiple molds 606 on one mounting ring 605, rapid switching can be achieved during the replacement of the mold 606, greatly improving the replacement efficiency, and thus enhancing the overall processing efficiency of the drilling and tapping machine body 1. At the same time, during the rotation of the driving column 705, the two mounting plates 701 can be simultaneously driven to engage with the two positioning blocks 607, realizing the rapid fixation of the mounting ring 605 on the turntable 604, further improving the installation efficiency, and ensuring that the equipment can be efficiently and stably put into subsequent processing.
