Description

Technical Field

[0001] This utility model relates to the field of tapping machines, and in particular to a high-precision drilling and tapping machine. Background Technology

[0002] A tapping machine is a mechanical processing device that processes internal threads, screws, or threads on the inner surface of holes in various parts such as machine housings, equipment end faces, nuts, and flanges with different specifications of through holes or blind holes.

[0003] Utility model with publication number CN217166832U discloses a tapping machine, including a base, a column, a worktable, and a working part; it also includes a pressure rod; a plurality of radially distributed strip-shaped slots are formed on the worktable; the pressure rod passes through the strip-shaped slots, and its upper end is provided with a contact that abuts against the workpiece or a fixture, and its lower end extends out of the lower end face of the worktable; the pressure rod is connected to a fastening nut that abuts against the lower end face of the worktable;

[0004] The tapping machine in the above technical solution requires workers to align the workpiece to be processed with the tapping drill bit and install it in the clamping device before tapping. With manual calibration, it is not easy to guarantee the accuracy of the thread position after processing, and the processing efficiency is low. Utility Model Content

[0005] To facilitate thread processing by tapping machines, this application provides a high-precision drilling and tapping machine.

[0006] The high-precision drilling and tapping machine provided in this application adopts the following technical solution:

[0007] A high-precision drilling and tapping machine includes a base, a drilling device, and a tapping device. The drilling device and the tapping device are fixedly connected to the base. A turntable is rotatably connected to the base in a vertical direction. The turntable has multiple placement slots evenly distributed around the central axis of the turntable. The turntable is provided with multiple sets of clamping mechanisms, each set corresponding to one of the placement slots. Each clamping mechanism includes several clamping blocks and a driving assembly. The clamping blocks are slidably connected to the turntable along an axis perpendicular to the placement slots. The driving assembly is used to simultaneously drive the sliding of the multiple clamping blocks.

[0008] By adopting the above technical solution, the workpiece to be processed is placed in the placement groove. The drive component simultaneously drives multiple clamping blocks to slide towards the central axis of the placement groove, so that multiple clamping blocks simultaneously abut against the workpiece to be processed, clamping and centering the workpiece to be processed, making the central axis of the workpiece to be processed coaxial with the central axis of the placement groove, improving the coaxiality of the workpiece to be processed, and reducing the time for manual alignment and clamping, thereby improving processing efficiency.

[0009] Preferably, the drive assembly includes a first cylinder and a plurality of inclined rods, the plurality of inclined rods being fixedly connected to corresponding clamping blocks, and the ends of the plurality of inclined rods away from the corresponding clamping blocks being respectively passed through and slidably connected to adjacent clamping blocks. The first cylinder is fixedly connected to the turntable, and one end of the piston rod of the first cylinder is fixedly connected to any clamping block.

[0010] By adopting the above technical solution, the first cylinder drives any clamping block to slide towards the central axis of the placement groove. When the clamping block moves, the inclined rod on the clamping block transmits and converts force through the inclined surface, causing adjacent clamping blocks to move together. This allows multiple clamping blocks to slide the same distance towards the central axis of the placement groove, clamping and centering the workpiece to be processed. This makes the central axis of the workpiece coaxial with the central axis of the placement groove, improving the coaxiality of the workpiece and reducing the time for manual alignment and clamping, thereby improving processing efficiency.

[0011] Preferably, the clamping block has an abutment groove on one side near the central axis of the placement groove, and the abutment groove is tapered from one end near the central axis of the placement groove to the end away from the central axis of the placement groove.

[0012] By adopting the above technical solution, the contact area and friction between the clamping block and the clamped workpiece are increased, reducing the possibility of the clamped workpiece rotating during drilling and tapping.

[0013] Preferably, it also includes a feeding mechanism, which includes a feeding plate and a second cylinder. The feeding plate is slidably connected to the machine base along an axis perpendicular to the turntable, and the second cylinder is fixedly connected to the machine base. One end of the piston rod of the second cylinder is detachably connected to the feeding plate.

[0014] By adopting the above technical solution, the piston movement of the piston rod on the second cylinder drives the unloading plate to reciprocate. When the unloading plate slides away from the central axis of the turntable, the unloading plate pushes the workpiece out of the abutment plate to complete the unloading, thereby improving processing efficiency.

[0015] Preferably, the feeding mechanism further includes a slide rail and a bolt. The slide rail is fixedly connected to the piston rod of the second cylinder. The feeding plate is slidably connected to the slide rail in the vertical direction. The feeding plate has multiple through holes evenly opened in the vertical direction. The bolt passes through any one of the through holes and is threaded onto the slide rail.

[0016] By adopting the above technical solution, the position of the cutting plate on the slide rail can be adjusted by sliding the cutting plate, so that the cutting plate can contact workpieces of different heights to complete the cutting. The cutting plate is fixed by bolts, which facilitates the adjustment of the position of the cutting plate.

[0017] Preferably, the drilling device includes a first head for mounting a drill bit and a first lifting mechanism. The first head is slidably connected to the base in a vertical direction. The central axis of the drill bit on the first head is located on the moving path of the central axis of the placement slot. The first lifting mechanism is used to drive the sliding of the first head.

[0018] By adopting the above technical solution, when the turntable rotates, the central axis of the workpiece to be processed, which is held on the placement slot, is made coaxial with the central axis of the drill bit directly above it, thereby improving the coaxiality of the workpiece to be processed.

[0019] Preferably, the tapping device includes a second tapping head and a second lifting mechanism for mounting the tap. The second tapping head is slidably connected to the base in a vertical direction. The central axis of the tap on the second tapping head is located on the moving path of the central axis of the placement groove. The second lifting mechanism is used to drive the sliding of the second tapping head.

[0020] By adopting the above technical solution, when the turntable belt rotates, the central axis of the workpiece to be processed, which is held on the placement groove, is made coaxial with the central axis of the tap directly above it, thereby improving the coaxiality of the workpiece to be processed.

[0021] The main technical effects of this utility model are reflected in the following aspects:

[0022] 1. This utility model sets up multiple clamping mechanisms to place the workpiece to be processed in the placement groove. The drive component simultaneously drives multiple clamping blocks to slide towards the central axis of the placement groove, so that multiple clamping blocks simultaneously abut against the workpiece to be processed, clamping and centering the workpiece to be processed, making the central axis of the workpiece to be processed coaxial with the central axis of the placement groove, improving the coaxiality of the workpiece to be processed, and reducing the time for manual alignment and clamping, thereby improving processing efficiency.

[0023] 2. This utility model allows multiple clamping blocks to slide together. A first cylinder drives any one of the clamping blocks to slide towards the central axis of the placement groove. When the clamping block moves, the inclined rod on the clamping block transmits and converts force through the inclined surface, causing adjacent clamping blocks to move together. This means that multiple clamping blocks slide the same distance towards the central axis of the placement groove, clamping and centering the workpiece to be processed. This makes the central axis of the workpiece coaxial with the central axis of the placement groove, improving the coaxiality of the workpiece and reducing the time for manual alignment and clamping, thereby improving processing efficiency.

[0024] 3. This utility model allows the material feed plate to be slidably connected to the slide rail. By sliding the material feed plate, the position of the material feed plate on the slide rail can be adjusted, so that the material feed plate can contact workpieces of different heights to complete the feeding. The material feed plate is fixed with bolts, which facilitates the adjustment of the position of the material feed plate. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0030] This application discloses a high-precision drilling and tapping machine.

[0031] Reference Figures 1-3 A high-precision drilling and tapping machine includes a base 1, a drilling device 4, and a tapping device 5. The drilling device 4 and the tapping device 5 are respectively mounted on the base 1. A turntable 11 is rotatably connected to the base 1 in the vertical direction. A servo motor 12 is fixedly connected to the base 1. The output shaft of the motor is coaxial and fixedly connected to the turntable 11 to drive the rotation of the turntable 11. The turntable 11 has four placement slots 111, which are evenly distributed around the central axis of the turntable 11. Four sets of clamping mechanisms 2 are also installed on the turntable 11, each corresponding to one of the placement slots 111.

[0032] Reference Figures 1-3Each clamping mechanism 2 includes three clamping blocks 21 and a drive assembly 22. The three clamping blocks 21 are slidably connected to the turntable 11 along an axis perpendicular to the placement groove 111. The drive assembly 22 is used to simultaneously drive the sliding of multiple clamping blocks 21. The workpiece to be processed is placed in the placement groove 111, and the drive assembly 22 simultaneously drives multiple clamping blocks to slide towards the central axis of the placement groove 111, so that multiple clamping blocks 21 simultaneously abut against the workpiece to be processed, clamping and centering the workpiece to be processed, making the central axis of the workpiece to be processed coaxial with the central axis of the placement groove 111, improving the coaxiality of the workpiece to be processed, and reducing the time for manual alignment and clamping, thereby improving processing efficiency.

[0033] Reference Figures 1-3 The drive assembly 22 includes a first cylinder 221 and several inclined rods 222. The inclined rods 222 are fixedly connected to the corresponding clamping blocks 21. The ends of the inclined rods 222 away from the corresponding clamping blocks 21 are respectively passed through and slidably connected to the adjacent clamping blocks 21. The inclined rods 222 on both sides of the clamping block 21 are staggered, that is, the inclined rod 222 on one side is located at the upper end of the clamping block 21, and the inclined rod 222 on the other side is located at the bottom end of the clamping block 21, reducing the possibility of interference between the inclined rods 222 during the sliding of the clamping block 21. The first cylinder 221 is fixedly connected to the turntable 11, and one end of the piston rod of the first cylinder 221 is fixedly connected to any clamping block 21.

[0034] Reference Figures 1-3 The first cylinder 221 drives any clamping block 21 to slide towards the central axis of the placement groove 111. When the clamping block 21 moves, the inclined rod 222 on the clamping block 21 transmits and converts force through the inclined surface, so that adjacent clamping blocks 21 move together. This means that multiple clamping blocks 21 slide the same distance towards the central axis of the placement groove 111, so that multiple clamping blocks 21 clamp and center the part to be processed, making the central axis of the part to be processed coaxial with the central axis of the placement groove 111, improving the coaxiality of the part to be processed, and reducing the time for manual alignment and clamping, thereby improving processing efficiency.

[0035] Reference Figures 1-3 The clamping block 21 has an abutment groove 211 on its side near the central axis of the placement groove 111. The abutment groove 211 is tapered from one end near the central axis of the placement groove 111 to the other end away from the central axis of the placement groove 111. This increases the contact area and friction between the clamping block and the clamped workpiece, reducing the possibility of the clamped workpiece rotating during drilling and tapping.

[0036] Reference Figure 1 and Figure 3The system also includes a feeding mechanism 3, which comprises a feeding plate 31 and a second cylinder 32. The feeding plate 31 is slidably connected to the machine base 1 along an axis perpendicular to the turntable 11. The second cylinder 32 is fixedly connected to the machine base 1, and one end of the piston rod of the second cylinder 32 is detachably connected to the feeding plate 31. The piston movement of the piston rod on the second cylinder 32 drives the feeding plate 31 to reciprocate. When the feeding plate 31 slides away from the central axis of the turntable 11, the feeding plate 31 pushes the workpiece out of the abutment plate, completing the feeding process and improving processing efficiency.

[0037] Reference Figure 1 and Figure 3 The unloading mechanism 3 also includes a slide rail 33 and bolts 34. The slide rail 33 is fixedly connected to the piston rod of the second cylinder 32. The unloading plate 31 is slidably connected to the slide rail 33 in the vertical direction. Multiple through holes 311 are evenly opened in the vertical direction on the unloading plate 31. The bolts 34 pass through any one of the through holes 311 and are threadedly connected to the slide rail 33. By sliding the unloading plate 31, the position of the unloading plate 31 on the slide rail 33 can be adjusted so that the unloading plate 31 can contact workpieces of different heights to complete the unloading. The bolts 34 are used for fixing, which facilitates the adjustment of the position of the unloading plate 31.

[0038] Reference Figure 1 and Figure 3 The drilling device 4 includes a first head 41 for mounting a drill bit 43 and a first lifting mechanism 42. The first head 41 is slidably connected to the base 1 in a vertical direction. The central axis of the drill bit 43 on the first head 41 is located on the moving path of the central axis of the placement groove 111. The first lifting mechanism 42 is used to drive the sliding of the first head 41. The first lifting mechanism 42 includes a first electric cylinder 421 and a first slide rail. The first head 41 is slidably connected to the first slide rail in a vertical direction. The first electric cylinder 421 is fixedly connected to the base 1. One end of the output shaft of the first electric cylinder 421 is fixedly connected to the first head 41. When the turntable 11 drives the placement groove 111 on the turntable 11 to rotate, the slide rail 33 makes the central axis of the workpiece to be processed held on the placement groove 111 coaxial with the central axis of the drill bit 43 directly above it, thereby improving the coaxiality of the workpiece to be processed.

[0039] Reference Figure 1 and Figure 3The tapping device 5 includes a second head 51 for mounting a tap 53 and a second lifting mechanism 52. The second head 51 is slidably connected to the base 1 in a vertical direction. The central axis of the tap 53 on the second head 51 is located on the moving path of the central axis of the placement groove 111. The second lifting mechanism 52 is used to drive the sliding of the second head 51. The second lifting mechanism 52 includes a second electric cylinder 521 and a second slide rail 522422. The second head 51 is slidably connected to the second slide rail 522422 in a vertical direction. The second electric cylinder 521 is fixedly connected to the base 1. The two ends of the output shaft of the second electric cylinder 521 are fixedly connected to the second head 51. When the turntable 11 drives the placement groove 111 on the turntable 11 to rotate, the central axis of the workpiece to be processed held on the placement groove 111 is made coaxial with the central axis of the tap 53 directly above it, thereby improving the coaxiality of the workpiece to be processed.

All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
