[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] In the description of this utility model, "more than" means two or more, and "greater than," "less than," "exceeding," etc., are understood to exclude the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0035] Reference Figure 1 A processing device for disc-shaped workpieces includes a machine base 100, a worktable 200, a drilling and tapping unit 300, and a milling unit 400. The worktable 200 is rotatably mounted on the machine base 100, and a rotary drive assembly 500 is connected to the worktable 200. The drilling and tapping unit 300 and the milling unit 400 are fixed on the machine base 100 and arranged around the worktable 200. When a disc-shaped workpiece is placed on the worktable 200, the worktable 200 rotates through the rotary drive assembly 500, so that the positions on the disc-shaped workpiece that need to be processed are sequentially rotated to below the milling unit 400 and the drilling and tapping unit 300 for milling, drilling, tapping, and other processing operations. This allows a single machine to perform milling, drilling, and tapping simultaneously, improving production efficiency.

[0036] Reference Figure 8 The milling unit 400 includes a milling spindle 410 and a headstock 420. The milling spindle 410 is fixedly mounted on the headstock 420, and the headstock 420 is fixed on the machine base 100. The milling spindle 410 mills the disc workpiece.

[0037] Reference Figure 2 The drilling and tapping unit 300 includes a drive shaft 310, a drilling and tapping drive component 320, a drill bit 330, a tap 340, a lifting mechanism 350, and a feed mechanism 360. At least two drive shafts 310 are used, and the two drive shafts 310 are arranged in layers. The drilling and tapping drive component 320 is used to drive the drive shaft 310 to rotate. The drive shaft 310 is mounted on the lifting mechanism 350, and the lifting mechanism 350 is mounted on the feed mechanism 360.

[0038] The drive shaft 310 can be equipped with drill bit 330 and tap 340 according to processing needs. The two drive shafts 310 are moved up and down by the lifting mechanism 350 so that the two drive shafts 310 are respectively facing the preset processing position. At the same time, the two drive shafts 310 are fed by the tool feeding mechanism 360, so that the two drive shafts 310 can perform drilling or tapping in the same position, achieving precise processing and improving the yield.

[0039] Reference Figure 12 , 13The rotary drive assembly 500 includes a rotary shaft 510, a driving synchronous pulley 520, a driven synchronous pulley 530, and a rotary drive component 540. The top of the rotary shaft 510 is fixedly connected to the center of the worktable 200. The driving synchronous pulley 520 is connected to the rotary drive component 540. The driven synchronous pulley 530 is fitted onto the bottom of the rotary shaft 510. A synchronous belt is wound between the driving synchronous pulley 520 and the driven synchronous pulley 530. The rotary drive component 540 drives the driving synchronous pulley 520 to rotate and transmits the rotation of the driven synchronous pulley 530 through the synchronous belt, thereby causing the rotary shaft 510 to drive the worktable 200 to rotate.

[0040] Reference Figure 14 To ensure that the worktable 200 stops accurately, the rotary drive assembly 500 also includes an angle gear 550, a positioning rod 560, and a positioning cylinder 570. The angle gear 550 is fitted onto the bottom of the rotary shaft core 510 and is located below the driven synchronous wheel 530. Multiple tooth grooves 551 are provided on the angle gear 550. The positioning rod 560 is connected to the positioning cylinder 570.

[0041] When the worktable 200 stops rotating, the positioning cylinder 570 pushes the positioning rod 560, causing the positioning rod 560 to insert into the tooth groove 551. This prevents the rotating shaft 510 from rotating on its own during processing, ensuring that the workpiece will not shift position due to the rotation of the worktable 200, thus affecting the processing accuracy.

[0042] Reference Figure 15 To further improve the positioning effect, a positioning plate 210 is fixed at the bottom of the worktable 200. The edge of the positioning plate 210 has a positioning slot 211. A positioning mold 220 is matched with the positioning slot 211. The positioning mold 220 is connected to the mold cylinder 230. The positioning cylinder 570 is fixed on the machine base 100. The mold cylinder 230 is used to push the positioning mold 220 so that the positioning mold 220 is engaged in the positioning slot 211, so that the worktable 200 stops rotating and is fixed in the stop position.

[0043] In this embodiment, since two drilling and tapping units 300 are used and one milling unit 400 is used, three positioning slots 211 are opened on the edge of the positioning plate 210. The three positioning slots 211 correspond to the three processing positions of the disc workpiece.

[0044] Reference Figure 13 The positioning cylinder 570 and the rotary drive component 540 are fixed at both ends of the mounting plate 580, the mounting plate 580 is fixed on the base 590, and the base 590 is sleeved on the outside of the rotating shaft core 510.

[0045] Reference Figure 1As shown, in this embodiment, two drilling and tapping units 300 are used, and one milling unit 400 is used. The milling unit 400 is located between the two drilling and tapping units 300. The worktable 200 rotates clockwise so that the workpiece passes through the milling unit 400 and the two drilling and tapping units 300 in sequence.

[0046] The first drilling and tapping unit 300 uses three drive shafts 310, and drill bits 330 are mounted on each of the three drive shafts 310.

[0047] The second drilling and tapping unit 300 uses three drive shafts 310. Drill bits 330 are installed on the drive shafts 310 located in the upper and middle layers, and taps 340 are installed on the drive shaft 310 located in the lower layer.

[0048] The specific workflow is as follows:

[0049] Step 1: The milling unit 400 first performs milling on the preset machining position on the disc workpiece to complete the milling.

[0050] Step 2: Rotary drive assembly 500 rotates worktable 200, causing the preset processing position to rotate to the first drilling and tapping processing unit 300, so that the first drilling and tapping processing unit 300 performs drilling operation, completing the drilling operation of the first hole;

[0051] Step 3: The rotary drive assembly 500 rotates the worktable 200 again, so that the preset processing position is rotated to the second drilling and tapping processing unit 300. The feed mechanism 360 works, so that the drive shaft 310 located on the upper layer feeds in and performs the first drilling operation of the second hole. After the drilling is completed, the feed mechanism 360 retracts the tool.

[0052] Step 4: The lifting mechanism 350 moves the drive shaft 310 located in the middle layer to the working position, and the feed mechanism 360 feeds the hole drilled in the first time to perform a second drilling, so that the diameter of the hole is enlarged. After the hole enlargement is completed, the feed mechanism 360 retracts the tool.

[0053] Step 5: The lifting mechanism 350 moves upward, causing the drive shaft 310 located on the lower layer to move to the working position and feed through the feed mechanism 360, so that the tap 340 taps the hole.

[0054] This enables a single machine to perform milling, drilling, and tapping simultaneously, improving production efficiency; and it allows drilling or tapping to be performed at the same location, achieving precision machining and improving yield.

[0055] Reference Figure 1 , 10To ensure that the disc workpiece does not detach from the worktable 200 during processing, a clamping mechanism 600 is provided. The clamping mechanism 600 includes a stand 610, a lifting cylinder 620, and a pressure plate 630. The stand 610 is fixed on the machine base 100. The lifting cylinder 620 is installed at the front end of the stand 610. The piston rod of the lifting cylinder 620 is connected to a force transmission plate 640. A guide shaft 650 is mounted on the force transmission plate 640. A bearing clamping plate 660 is rotatably mounted on the guide shaft 650. The pressure plate 630 is installed at the bottom of the bearing clamping plate 660, so that the pressure plate 630 rotates about the guide shaft 650.

[0056] A bearing clamping plate 660 is rotatably mounted on the guide shaft 650. The bearing clamping plate 660 makes the force transmission plate 640 more stable during movement, preventing wobbling. A pressure plate 630 is installed at the bottom of the bearing clamping plate 660, which is used to clamp the disc workpiece, ensuring that the disc workpiece will not detach from the worktable 200 due to cutting forces during processing, thus guaranteeing the stability and safety of processing. The design of the clamping mechanism 600 allows the processing equipment of this utility model to adapt to disc workpieces of different sizes, improving the versatility and practicality of the equipment.

[0057] After the disc workpiece is placed on the worktable 200, the lifting cylinder 620 descends to press the pressure plate 630 on top of the disc workpiece, so that the pressure plate 630 contacts the disc workpiece. During the rotation of the disc workpiece, the pressure plate 630 rotates with the disc workpiece to avoid friction between the pressure plate 630 and the disc workpiece, which would cause scratches on the surface of the disc workpiece and affect product quality.

[0058] Reference Figure 9 As shown, the milling spindle 410 is fixed on the adjusting plate 430, and the cutter shaft of the milling spindle 410 faces obliquely downward. The adjusting plate 430 has multiple first arc-shaped waist holes 431. The first adjusting screws are installed in the first arc-shaped waist holes 431 and are fixed on the machine head base 420. The lower corner of the adjusting plate 430 also has a first fixing screw hole 432. The first fixing screw is installed in the first fixing screw hole 432 and is fixed on the machine head base 420.

[0059] In this embodiment, the first fixing screw hole 432 is located at the lower left corner of the adjusting plate 430, and the cutter shaft of the milling spindle 410 faces the lower left, so that the axis of the cutter shaft forms an angle with the horizontal axis, which is the feed angle of the milling spindle 410.

[0060] According to the processing requirements, the feed angle of the milling spindle 410 needs to be adjusted. At this time, loosen the first adjusting screw and then rotate the adjusting plate 430 to the left, so that the adjusting plate 430 rotates around the first fixing screw. At this time, the screw of the first adjusting screw moves in the first arc-shaped waist hole 431. After the feed angle is adjusted to the position, tighten the first adjusting screw to fix the position of the adjusting plate 430, thereby completing the adjustment of the feed angle of the milling spindle 410.

[0061] Reference Figure 9 As shown, due to the large weight of the milling spindle 410, an auxiliary adjustment structure is provided to make effortless adjustment of the feed angle of the milling spindle 410. A first base plate 450 is fixed on the headstock 420. The first base plate 450 is located below the adjustment plate 430, and an adjustment gap 401 is formed between the first base plate 450 and the adjustment plate 430.

[0062] In the first auxiliary adjustment method, an adjusting rod is vertically installed on the first base plate 450. The adjusting rod is threadedly connected to the first base plate 450, and the top of the adjusting rod rests on the bottom of the adjusting plate 430. When adjusting, the adjusting rod is rotated to lift the adjusting plate 430 upward, causing the adjusting plate 430 to rotate about the first fixing screw as an axis.

[0063] The second auxiliary adjustment method involves inserting a first angle plate 460 into the adjustment gap 401. The first angle plate 460 has a wedge-shaped part 461, which is used to insert into the adjustment gap 401. Since the wedge-shaped part 461 has an inclined surface, the inclination angle of the inclined surface corresponds to the required inclination angle of the adjustment plate 430. When the bottom surface of the adjustment plate 430 is flush with the inclined surface of the wedge-shaped part 461, it indicates that the feed angle of the milling spindle 410 has been adjusted to the correct position. Tighten the first fixing screw and remove the first angle plate 460.

[0064] Of course, two auxiliary adjustment methods can also be used at the same time. After the first adjustment rod lifts the adjustment plate 430 to the preset position, the first angle plate 460 is inserted into the first adjustment gap 401 to further strengthen and fix the position of the adjustment plate 430, so that the adjustment plate 430 can remain stable during processing.

[0065] Reference Figure 11 As shown, in this embodiment, three drive shafts 310 are used, each drive shaft 310 has a drive wheel 311, and a transmission wheel 312 is installed between the three drive wheels 311. Any one of the drive wheels 311 is connected to the drilling and tapping drive component 320 to realize the synchronous driving rotation of the three drive shafts 310 by the drilling and tapping drive component 320.

[0066] Reference Figures 3 to 5As shown, the lifting mechanism 350 includes a tool assembly mounting plate 351, a mounting base plate 352, a lifting screw 353, and a lifting nut 354. The drive shaft 310 is obliquely fixed on the tool assembly mounting plate 351, so that the drive shaft 310 faces the lower left or lower right, and the axis of the drive shaft 310 forms an angle with the horizontal axis. This angle is the feed angle of the drive shaft 310.

[0067] A lifting nut 354 is fixed to the back of the tool assembly mounting plate 351. The lifting nut 354 is mounted on the lifting screw 353. One end of the lifting screw 353 is connected to the lifting drive component 355. The other end of the lifting screw 353 is equipped with a bearing seat. The bearing seat is fixed on the mounting plate 352. The mounting plate 352 is connected to the tool feed mechanism 360.

[0068] During lifting operations, the lifting drive component 355 drives the lifting screw 353 to rotate, causing the lifting nut 354 to move along the lifting screw 353, thereby moving the tool assembly mounting plate 351.

[0069] In this embodiment, the lifting screw 353 is arranged obliquely. When the lifting screw 353 faces downward to the left, the drive shaft 310 faces downward to the right, or when the lifting screw 353 faces downward to the right, the drive shaft 310 faces downward to the left. The axis of the lifting screw 353 and the axis of the drive shaft 310 intersect each other, and the lifting drive component 355 is fixed on the mounting base plate 352.

[0070] To maintain stable lifting and moving, a first slide rail slider assembly 356 is installed between the mounting base plate 352 and the blade assembly mounting plate 351. The first slide rail in the first slide rail slider assembly 356 is fixed on the mounting base plate 352, and the first slider in the first slide rail slider assembly 356 is fixed on the back of the blade assembly mounting plate 351.

[0071] Reference Figure 2 , 3 As shown in Figure 6, the feed mechanism 360 includes a feed seat 361, a feed screw 362, a feed nut 363, and a feed drive 364. The feed screw 362 is rotatably mounted on the feed seat 361. One end of the feed screw 362 is connected to the feed drive 364, and the other end of the feed screw 362 is equipped with a bearing seat, which is fixed on the feed seat 361. The feed nut 363 is mounted on the back of the mounting plate 352.

[0072] During tool advance and retraction, the tool advance drive 364 drives the tool advance screw 362 to rotate, causing the tool advance nut 363 to move relative to the tool advance nut 363, thereby causing the tool advance holder 361 to reciprocate along the tool advance screw 362, so that the tool advance holder 361 moves toward or away from the workpiece, thereby realizing tool advance and retraction.

[0073] In this embodiment, the feed screw 362 is obliquely arranged and faces downward to the left or downward to the right, so that the axis of the feed screw 362 is parallel to the axis of the cutter shaft.

[0074] To maintain stability during tool advance and retraction, a second slide rail slider assembly 368 is installed between the mounting plate 352 and the tool feed seat 361. The second slide rail in the second slide rail slider assembly 368 is fixed to the tool feed seat 361, and the second slider in the second slide rail slider assembly 368 is fixed to the back of the mounting plate 352.

[0075] Reference Figure 9 As shown, due to the large weight of the drilling and tapping unit 300, an auxiliary adjustment structure is provided to make effortless adjustment of the feed angle of the drilling and tapping unit 300.

[0076] The feed holder 361 is mounted on the head frame 365. The feed holder 361 has multiple second arc-shaped waist holes 3611. Second adjusting screws are inserted into the second arc-shaped waist holes 3611 and are fixed to the head frame 365. A second base plate 366 is fixed on the upper part of the head frame 365. The second base plate 366 is located below the feed holder 361. A second adjusting gap 301 is formed between the second base plate 366 and the feed holder 361. A second fixing screw hole 3612 is also opened at the lower corner of the feed holder 361. A second fixing screw is inserted into the second fixing screw hole 3612 and is fixed to the head frame 365.

[0077] According to the processing requirements, the feed angle of the drilling and tapping unit 300 needs to be adjusted. At this time, loosen the second adjusting screw and then rotate the adjusting plate 430 to the left, so that the adjusting plate 430 rotates around the second fixing screw. At this time, the screw of the second adjusting screw moves in the second arc-shaped waist hole 3611. After the feed angle is adjusted to the position, tighten the second adjusting screw to fix the position of the adjusting plate 430, thereby completing the adjustment of the feed angle of the milling spindle 410.

[0078] In the first auxiliary adjustment method, a second adjusting rod is vertically installed on the second base plate 366. The second adjusting rod is threadedly connected to the second base plate 366, and the top of the second adjusting rod rests against the bottom of the feed seat 361. When adjusting, the second adjusting rod is rotated to push the feed seat 361 upward, causing the feed seat 361 to rotate about the second fixing screw as an axis.

[0079] The second auxiliary adjustment method involves inserting a second angle plate 367 into the second adjustment gap 301. The second angle plate 367 is triangular, and its tilt angle corresponds to the required tilt angle of the adjustment plate 430. When the bottom surface of the adjustment plate 430 is flush with the inclined surface of the second angle plate 367, it indicates that the feed angle of the milling spindle 410 has been adjusted to the correct position. Tighten the second adjustment screw and remove the second angle plate 367.

[0080] The second angle plate 367 is inserted into the second adjustment gap 301. Since the second angle plate 367 has an inclined surface, the feed seat 361 rotates as the second angle plate 367 is inserted. At the same time, the flip angle of the feed seat 361 increases as the insertion depth of the second angle plate 367 increases.
