[0033] Example

[0034] To address the issues of low efficiency in existing drilling equipment during practical use, this paper refers to... Figure 1 and Figure 2 As shown, this application discloses a multi-station drilling equipment, including a machine base 10, an interleaved feeding mechanism 20, and a drilling mechanism 30;

[0035] The staggered feeding mechanism 20 includes a feeding base 21 disposed above the machine base 10 along a first direction. A first sliding platform 22 is disposed above the feeding base 21. A first moving drive unit 23 for driving the first sliding platform 22 to move along the first direction is disposed above one side of the feeding base 21. A second sliding platform 24 is disposed in the middle of the feeding base 21. A second moving drive unit 25 for driving the second sliding platform 24 to move along the first direction is disposed in the middle of one side of the feeding base 21. A first lifting drive unit 27 is disposed at the bottom of the second sliding platform 24. A lifting base 26 connected to the first lifting drive unit 27 is disposed above the second sliding platform 24. Fixed bearing fixtures 28 for bearing workpieces are respectively disposed above the first sliding platform 22 and the lifting base 26. As a preferred embodiment, the first moving drive unit 23 and the second moving drive unit 25 mentioned above are rodless cylinders with the same structure.

[0036] The drilling mechanism 30 includes a second lifting drive unit 31 located at the rear of the feeding base 21 and mounted on the machine base 10, a servo power turret 32 ​​connected to the second lifting drive unit 31, and several drilling tools 34 mounted on several tool shafts of the servo power turret 32.

[0037] In practice, the operator first places a motor housing to be processed on the fixed support fixture 28 above the first sliding platform 22 and fixes the motor housing using the fixed support fixture 28. Then, the first moving drive unit 23 drives the first sliding platform 22 to the processing position. Next, the second lifting unit drives the servo-powered turret 32 ​​to descend in real time and drills holes in several positions on the motor housing using several drilling tools 34. During this process, the operator places another motor housing to be processed on the fixed support fixture 28 on the lifting base 26 and fixes it using the fixed support fixture 28. After the drilling of the motor housing is completed, the first moving drive unit 23 drives the first sliding platform 22 in the loading direction. Simultaneously, the second moving drive unit 25 drives the second sliding platform 24 to move in the processing direction. When the second sliding platform 24 is about to meet the first sliding platform 22, the first lifting drive unit 27 drives the lifting base 26 to descend first. After the first sliding platform 22 and the first sliding platform 22 meet, the first lifting drive unit 27 drives the lifting base 26 to rise. When the lifting base 26 reaches the processing position, the second lifting drive unit 31 drives the servo power turret 32 ​​to descend in real time and drills several positions of the motor housing through several drilling tools 34. By repeating the above operation, the downtime of the drilling mechanism 30 can be reduced and the work efficiency can be improved.

[0038] In order to enable the sliding installation of the first sliding platform 22 and the second sliding platform 24, this application provides a first step 211 and a second step 212 on the upper and middle parts of the inner walls on both sides of the feeding base 21 in the second direction, respectively.

[0043] Driven by the first moving drive unit 23, the first sliding stage 22 will slide above the two first linear guide rails 2111, and driven by the second moving drive unit 25, the second sliding stage 24 will slide above the two second linear guide rails 2121.

[0044] Based on the above scheme, this application also provides a first clearance groove 213 and a second clearance groove 214 on the inner walls of both sides of the feeding base 21 in the second direction, respectively, at its upper part and middle part.

The base 281 is provided with four small clamping cylinders 284 for extending the piston rod into the contour groove 283. In specific implementation, the four drilling positions of the motor housing will be mounted inside the four lugs 282. When fixing the motor housing, the four small clamping cylinders 284 fix the entire motor housing from all sides.

[0049] In a preferred embodiment, the first lifting drive unit 27 of this application includes a stand and a servo screw drive module 312. The stand is located at the rear of the feeding base 21 and is mounted on the machine base 10. The servo screw drive module 312 is vertically mounted on the stand facing the feeding base 21. The servo power turret 32 ​​is connected to the servo screw drive module 312. Under the drive of the servo screw module, the servo power turret 32 ​​can achieve lifting and lowering motion, thereby enabling several drilling tools 34 to perform drilling processing on several positions of the motor housing.

[0050] In a preferred embodiment, the second lifting drive unit 31 of this application is a linear cylinder. The linear cylinder is located at the bottom of the first sliding platform 22 and its piston rod passes through the first sliding platform 22 and is connected to the lifting base 26.
