Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0042] refer to Figures 1 to 7 ,like Figure 1As shown, this embodiment provides a bottom-mounted rotary multi-station tapping machine, including: a base 1, a tapping mechanism, and a rotating mechanism. The tapping mechanism is mounted on the frame 2 of the base 1; the rotating mechanism is mounted on the base 1 and is located below the tapping mechanism; wherein, the rotating mechanism includes a first motor 6, a turntable 7, several storage seats 8, and several clamping mechanisms 9. The first motor 6 is installed in a second screw hole 11 opened on the base 1; the turntable 7 is connected to the output end of the first motor 6; several storage seats 8 and several clamping mechanisms 9 are all mounted on the turntable 7, and the clamping mechanisms 9 are correspondingly distributed on the outer side of the storage seats 8. The storage seats 8 are used to place the parts to be processed, and the clamping mechanisms 9 are used to clamp the parts to fix and limit their position. The tapping mechanism is used to tap the fixed parts.

[0043] like Figure 4 and Figure 5 As shown, the clamping mechanism 9 includes: a first upright plate 91, a drive rod 97, a second upright plate 92, a connecting rod 93, and a clamping assembly. The first upright plate 91 is fixed on the turntable 7. The lower end of the drive rod 97 is pivotally connected to a first mounting seat 914 provided at one end of the first upright plate 91. The second upright plate 92 is detachably connected to the upper end of the drive rod 97. The upper end of the connecting rod 93 is pivotally connected to a second mounting seat 921 provided at one end of the second upright plate 92. The connecting rod 93 and the drive rod 97 are parallel to each other. The first mounting seat 914 and the second mounting seat 921 are diagonally distributed. The connecting rod 93 can be connected to the other end of the first upright plate 91. The clamping assembly is provided on the first upright plate 91 and the second upright plate 92. The clamping assembly is used to clamp the part to be tapped.

[0044] Preferably, the lower end of the connecting rod 93 is threaded onto the first upright plate 91, and the drive rod 97 is connected to the second upright plate 92 via a wing nut 99.

[0045] Specifically, the end of the connecting rod 93 away from the second vertical plate 92 has a first threaded portion 931, and the first vertical plate 91 has a first screw hole 911 for threading the first threaded portion 931.

[0046] like Figure 6 As shown, the drive rod 97 has a second threaded portion 971 at one end away from the first upright plate 91. The second upright plate 92 has a first through hole 923 for the second threaded portion 971 to pass through. A washer 98 is fitted on the second threaded portion 971. A third through hole 981 for the second threaded portion 971 to pass through is provided on the washer 98. A wing nut 99 is threaded onto the second threaded portion 971 and holds the washer 98 against the second upright plate 92. The wing nut 99 can connect the drive rod 97 to the second upright plate 92.

[0047] like Figure 5As shown, the clamping assembly includes a fixed limiting seat 95 and a swing limiting seat 96. The fixed limiting seat 95 is fixed to the first upright plate 91 by screws 913; the swing limiting seat 96 is pivotally connected to the second upright plate 92, and the fixed limiting seat 95 and the swing limiting seat 96 are arranged opposite to each other. The storage seat 8 is located below the fixed limiting seat 95 and the swing limiting seat 96.

[0048] Preferably, the screw 913 passes through the first upright plate 91 and is threaded into the second screw hole 952 of the fixed limiting seat 95. Additionally, the first upright plate 91 has a groove 912, in which the head of the screw 913 is accommodated. By providing the groove 912, the screw 913 can be hidden within it. The second upright plate 92 has a second through hole 922, in which the swing limiting seat 96 is pivotally connected.

[0049] like Figure 6 and Figure 7 As shown, the swing limit seat 96 is provided with a pair of extensions 961. Both the fixed limit seat 95 and the swing limit seat 96 have V-shaped grooves for clamping parts. The V-shaped groove on the swing limit seat 96 is formed between the pair of extensions 961. Parts with outer arc surfaces can be clamped in the pair of V-shaped grooves. Therefore, the fixed limit seat 95 and the swing limit seat 96 are arranged opposite to each other and can clamp parts, thus making the clamping assembly have a good clamping and limiting effect.

[0050] The clamping mechanism 9 is used as follows: Place the part on the holder 8, ensuring it is flush against the V-groove of the fixed limit seat 95. Tighten the wing nut 99 so that the V-groove of the swing limit seat 96 abuts against the part. Tighten the wing nut 99 to firmly clamp the part between the fixed limit seat 95 and the swing limit seat 96. To remove the part, reverse the twisting of the wing nut 99 to release the swing limit seat 96 from the clamp, allowing the part to be removed.

[0051] like Figure 1 and Figure 2 As shown, the tapping mechanism includes: a hydraulic cylinder 3, a second motor 4, and a tapping tool 5. The hydraulic cylinder 3 is mounted on the frame 2; the second motor 4 is mounted on the lower end of the hydraulic cylinder 3 via a motor bracket; and the tapping tool 5 is mounted on the output end of the second motor 4. The hydraulic cylinder 3 can drive the second motor 4 and the tapping tool 5 to move up and down, and the second motor 4 can drive the tapping tool 5 to rotate for tapping.

[0052] Preferably, the base 1 is provided with a storage drawer 12 for storing objects.

[0053] Working Process: The part to be tapped is installed at installation station 200 and clamped by clamping mechanism 9. Once the part is fixed, the first motor 6 starts, driving the turntable 7 to rotate 90 degrees clockwise. The part to be tapped rotates to tapping station 100 for tapping. During tapping, hydraulic cylinder 3 drives the second motor 4 and tapping cutter 5 to move downwards. After tapping cutter 5 moves to the set height, the second motor 4 starts, driving tapping cutter 5 to rotate, causing tapping cutter 5 to begin tapping the threads of the part. After tapping this part, the tapping mechanism resets. During this period, the operator installs another part to be tapped at installation station 200. After the first part is processed, the first motor 6 starts again, driving the turntable 7 to rotate 90 degrees clockwise, causing the second part to rotate to tapping station 100 for tapping. The process is repeated for subsequent parts. When the processed part rotates to unloading station 300, the operator can remove it.

[0054] This application includes multiple clamping mechanisms 9, which rotate in stages under the drive of the turntable 7, enabling multi-station operation. When tapping parts at the tapping station 100, the operator can disassemble the parts that have been tapped in the previous step at the unloading station 300, and install the parts to be tapped at the installation station 200. In this way, the installation, disassembly and tapping operations are carried out simultaneously, thereby improving production efficiency.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
