[0027] When processing, the one end of the cylindrical part with the preformed hole is clamped into the cylindrical clamping groove 531 to position the radial position of the cylindrical part, to reduce the possibility of the cylindrical part being inclined, and the positioning column 532 is inserted into the preformed hole of the cylindrical part to limit the rotation of the cylindrical part, so as to position the circumferential position of the cylindrical part, so as to improve the drilling and tapping quality. The second driving part 520 drives the sliding seat 510 to move to the corresponding position below the drilling mechanism 300 or the tapping mechanism 400, so as to drive the cylindrical part on the positioning seat 530 to move to the preset work station, and then the first driving part 220 drives the lifting seat 210 to move downward, so as to drive the drilling mechanism 300 and the tapping mechanism 400 to move downward, and the drilling and tapping processes are respectively performed on the cylindrical part by the drilling mechanism 300 and the tapping mechanism 400, so as to complete the processing of the threaded hole. Artificial transfer of the cylindrical part to different work stations and repositioning are not required, the drilling and tapping efficiency can be improved, and the processing precision of the threaded hole can be improved.

[0028] After the processing is completed, the cylindrical part is pulled out upward from the cylindrical clamping groove 531, so that the cylindrical part is convenient to take and place.

[0029] It should be noted that since the shape of the cylindrical clamping groove 531 matches the shape of the cylindrical part, the one end of the cylindrical part with the preformed hole is clamped into the cylindrical clamping groove 531, so as to position the radial position of the cylindrical part.

[0030] The one end of the cylindrical part is provided with a preformed hole, and the other end of the cylindrical part needs to be processed with a threaded hole. The shape of the positioning column 532 matches the shape of the preformed hole. Since the positioning column 532 is located at the eccentric position of the bottom surface of the cylindrical clamping groove 531, the positioning column 532 is inserted into the preformed hole of the cylindrical part to limit the rotation of the cylindrical part, so as to position the circumferential position of the cylindrical part.

[0031] The first driving part 220 can be a pneumatic cylinder, an oil cylinder or a linear slide module, which can drive the lifting seat 210 to move upward and downward.

[0032] The second driving part 520 can be a stroke pneumatic cylinder or a linear slide module, which can drive the sliding seat 510 to move and control the movement stroke of the sliding seat 510.

[0033] It can be understood that, referring to Figure 3 and Figure 4 , the upper end surface of the positioning column 532 is provided in a hemispherical shape. The hemispherical end surface of the positioning column 532 guides the positioning column 532 to be inserted into the preformed hole of the cylindrical part, which can improve the convenience and accuracy of clamping and positioning of the cylindrical part, and can reduce the collision and wear between the cylindrical part and the upper end of the positioning column 532.

[0034] It should be noted that the vertical height of the positioning column 532 is less than the depth of the cylindrical clamping groove 531, so when the cylindrical part is clamped into the cylindrical clamping groove 531, the end of the positioning column 532 abuts the end face of the cylindrical part, and the cylindrical part needs to be rotated to enable the positioning column 532 to align and be inserted into the pre-drilled hole of the cylindrical part. The hemispherical end face at the upper end of the positioning column 532 can reduce the contact area between the positioning column 532 and the cylindrical part, thereby reducing the frictional resistance.

[0035] It can be understood that, referring to Figure 1 and Figure 2 , the base 100 is provided with horizontal guide rails 110, and the sliding seat 510 is slidingly connected to the guide rails 110. The sliding seat 510 is guided by the guide rails 110 to move horizontally to a corresponding position below the drilling mechanism 300 or the tapping mechanism 400, which can improve the stability of the horizontal movement of the sliding seat 510, thereby improving the accuracy of the movement of the sliding seat 510 to the preset position, and thus improving the drilling and tapping processing accuracy.

[0036] It can be understood that, referring to Figure 1 , the drilling mechanism 300 includes a third driving member 310 and a drilling tool 320. The fixed end of the third driving member 310 is arranged on the lifting seat 210, and the drilling tool 320 is connected to the movable end of the third driving member 310. The third driving member 310 is used to drive the drilling tool 320 to rotate. When the first driving member 220 drives the lifting seat 210 to move downward, the third driving member 310 is also driven to move downward, and the drilling tool 320 is driven to rotate by the third driving member 310 to drill the cylindrical part. The depth of the drilling can be controlled by controlling the downward distance of the lifting seat 210.

[0037] It can be understood that, referring to Figure 1 , the tapping mechanism 400 includes a fourth driving member 410 and a tapping tool 420. The fixed end of the fourth driving member 410 is arranged on the lifting seat 210, and the tapping tool 420 is connected to the movable end of the fourth driving member 410. The fourth driving member 410 is used to drive the tapping tool 420 to rotate. When the first driving member 220 drives the lifting seat 210 to move downward, the fourth driving member 410 is also driven to move downward, and the tapping tool 420 is driven to rotate by the fourth driving member 410 to tap the cylindrical part. The depth of the tapping can be controlled by controlling the downward distance of the lifting seat 210.

[0038] It should be noted that the third driving member 310 and the fourth driving member 410 respectively drive the drilling tool 320 and the tapping tool 420 to rotate to drill and tap the cylindrical part, so that the drilling and tapping can be performed independently.

[0039] The third driving member 310 and the fourth driving member 410 can be servo motors or stepping motors, which can drive the drilling tool 320 and the tapping tool 420 to rotate.

[0040] It can be understood that, with reference to Figure 1 and Figure 2 , the translation mechanism 500 further comprises a pressing plate 540 and a fifth driving member 550, the fixed end of the fifth driving member 550 is arranged on the sliding base 510, the pressing plate 540 is arranged on the movable end of the fifth driving member 550, the pressing plate 540 is above the positioning seat 530, and the fifth driving member 550 is used to drive the pressing plate 540 to move up and down, and the following cylindrical member. By driving the pressing plate 540 to move up and down through the fifth driving member 550, the following cylindrical member, the axial position of the cylindrical member can be positioned to reduce the possibility of the cylindrical member moving up and down, thereby improving the position stability of the cylindrical member, and further improving the drilling and tapping quality. In addition, by limiting the upward movement of the cylindrical member through the pressing plate 540, the possibility that the drilling tool 320 and the tapping tool 420 will take the cylindrical member away from the cylindrical clamping groove 531 when the tool is retracted can be prevented.

[0041] It should be noted that the fifth driving member 550 can be a pneumatic cylinder or an electric push rod, etc., which can drive the pressing plate 540 to move up and down.

[0042] Specifically, with reference to Figure 2 , the pressing plate 540 is vertically penetrated by a guide hole 541. By passing through the guide hole 541, the drilling tool 320 and the tapping tool 420 guide the drilling tool 320 and the tapping tool 420 to move vertically, thereby improving the drilling and tapping processing precision.

Since the side wall of the cylindrical clamping groove 531 is provided with the chip removal groove 533, the metal scraps on the bottom wall of the cylindrical clamping groove 531 can be easily swept out of the cylindrical clamping groove 531 along the chip removal groove 533 by using a brush, thereby reducing the influence of the metal scraps on the clamping and positioning of the cylindrical member, and improving the positioning accuracy.
