In the motor shaft semicircular hole tapping device, the positioning hole 34 is positioned between the two adjacent motor shaft limiting holes 331, and due to the positioning effect of the limiting hole groups 33, the positioning hole 34 and the workpiece positioning unit 2, the left-right swing of the drilling shaft or the tapping screw tap 5 can be limited and the left-right swing of the motor shaft 4 can be limited in the process of feeding the drilling shaft or the tapping screw tap 5 to the drilling shaft or the tapping screw tap 5 for hole tapping or tapping on the wall surfaces of the two motor shafts 4, so that the cross section of the hole tapping or the tapping formed on the wall surface of the motor shaft 4 is semicircular, the hole tapping or the tapping of the motor shaft 4 can be aligned to other parts in subsequent assembly, and the assembly of the motor is facilitated. In addition, in each machining process, one drilling shaft or tapping screw tap 5 can simultaneously machine the holes or the tapping of the two motor shafts 4, so that the machining efficiency is improved.

As shown in fig. 1 and 2, during machining, the front end of a motor shaft 4 to be machined is placed into the motor shaft limiting holes 331, and one motor shaft 4 is placed into each motor shaft limiting hole 331, so that the front end of the motor shaft 4 is fixed with the tapping positioning unit 3, and the front end of the motor shaft 4 is prevented from moving relative to the tapping positioning unit 3; then, the rear end of the motor shaft 4 is placed into the workpiece positioning unit 2, then the positioning plate 31 of the tapping positioning unit 3 is pushed, the tapping positioning unit 3 is made to move towards the workpiece positioning unit 2, and finally the motor shaft 4 is fixed to the workpiece positioning unit 2, so that the motor shaft 4 and the station positioning unit are prevented from moving relatively; finally, the positioning hole 34 penetrates through the drilling shaft or the tapping screw tap 5, the drilling shaft or the tapping screw tap 5 at this time can be aligned to the position, needing to be drilled or tapped, of the wall surfaces of the two motor shafts 4 in the two adjacent motor shaft limiting holes 331 of the same limiting hole group 33, one half of the drilling shaft or the tapping screw tap 5 is aligned to the position, needing to be drilled or tapped, of the wall surface of the motor shaft 4 on one side, the other half of the drilling shaft or the tapping screw tap 5 is aligned to the position, needing to be drilled or tapped, of the wall surface of the motor shaft 4 on the other side, and the drilling shaft or the tapping screw tap 5 can be rotated to machine the drilled or tapped hole with the semicircular cross section on the wall surfaces of the two adjacent motor shafts 4.

In some embodiments, the tapping mechanism 32 includes a plurality of sets of limit holes 33 and a plurality of positioning holes 34, wherein each set of limit holes 33 cooperates with at least one positioning hole 34; or, the limit hole group 33 includes three motor shaft limit holes 331, and the three motor shaft limit holes 331 form two communicating sections 332, so that the limit hole group 33 needs to be matched with the two positioning holes 34; or, the limit hole group 33 includes four motor shaft limit holes 331, and the four motor shaft limit holes 331 form three communicating sections 332, so that the limit hole group 33 needs to be matched with three positioning holes 34.

It should be noted that the limit hole set 33 includes two motor shaft limit holes 331, and the two motor shaft limit holes 331 of the same set of limit hole set 33 are communicated. As shown in fig. 3 and 4, in the present embodiment, since the limit hole set 33 includes two motor shaft limit holes 331, the two motor shaft limit holes 331 form a communicating section 332, and thus, the limit hole set 33 needs to be matched with one of the positioning holes 34. When each group of the limit hole groups 33 exceeds two motor shaft limit holes 331, because the two adjacent motor shaft limit holes 331 are both of a communicating structure, the overall structure of the limit hole groups 33 is not firm enough and is easy to damage when being stressed too much, and when each group of the limit hole groups 33 is only provided with two motor shaft limit holes 331, the hole opening efficiency or the tapping efficiency is improved, and meanwhile, the firmness degree of the limit hole groups 33 can be ensured.

Optionally, the workpiece positioning unit 2 includes a clamping assembly 21, the clamping assembly 21 is provided with positioning grooves 22, the positioning grooves 22 correspond to the motor shaft limiting holes 331 one to one, and the motor shaft limiting holes 331 face the positioning grooves 22 corresponding thereto. The clamping assembly 21 is used for clamping the rear end of the motor shaft 4. When the motor shaft 4 is processed, the front end of the motor shaft 4 is placed into the motor shaft limiting hole 331, then the rear end of the motor shaft 4 is placed into the positioning groove 22, the rear end of the motor shaft 4 is clamped by the clamping component 21, and the motor shaft limiting hole 331 faces the positioning groove 22 corresponding to the motor shaft limiting hole 331, so that the front end and the rear end of the motor shaft 4 can be stably positioned, and the motor shaft 4 is prevented from swinging left and right during tapping. In addition, because the positioning grooves 22 correspond to the motor shaft limiting holes 331 one by one, the tapping mechanism 32 and the clamping component 21 can fix a plurality of motor shafts 4 at the same time, and therefore machining efficiency is improved.

Specifically, the clamping assembly 21 includes a lower clamp 211 and an upper clamp 212, the lower clamp 211 is connected to the base 1, the upper clamp 212 is disposed right above the lower clamp 211, and the upper clamp 212 moves closer to or away from the lower clamp 211. When machining, the rear end of the motor shaft 4 is placed on the upper surface of the lower clamp 211, when the upper clamp 212 moves close to the lower clamp 211, the upper clamp 212 presses down, the upper clamp 212 clamps the rear end of the motor shaft 4 on the upper surface of the lower clamp 211, and in addition, the lower clamp 211 is connected with the base 1, so that the motor shaft 4 is fixed to the base 1, and the motor shaft 4 is prevented from swinging left and right relative to the base 1 during hole opening or tapping.

Preferably, the positioning groove 22 is opened on the upper surface of the lower clamp 211 and/or on the lower surface of the upper clamp 212. In one embodiment, the positioning groove 22 is opened on the upper surface of the lower clamp 211, so that the rear end of the motor shaft 4 can be placed in the positioning groove 22 first, and then the motor shaft 4 is restricted from swinging left and right by pressing down the upper clamp 212. In another embodiment, the positioning groove 22 is opened in the lower surface of the upper jig 212, so that the motor shaft 4 can be restricted from swinging left and right by the positioning groove 22 in the lower surface of the upper jig 212 by pressing down the upper jig 212 after the rear end of the motor shaft 4 is placed on the upper surface of the lower jig 211. In another embodiment, the positioning grooves 22 are respectively opened on the upper surface of the lower fixture 211 and the lower surface of the upper fixture 212, so that when the upper fixture 212 is pressed down to the lower fixture 211, the positioning grooves 22 of the lower fixture 211 and the positioning grooves 22 of the upper fixture 212 are combined into a hole in which the motor shaft 4 can be placed, thereby limiting the left and right swing of the motor shaft 4.

In some embodiments, the clamping assembly 21 further comprises a driving mechanism 213, the driving mechanism 213 is mounted on the base 1, and an output end of the driving mechanism 213 is connected to the upper clamp 212. The output end of the driving mechanism 213 drives the upper clamp 212 to move, so as to clamp the motor shaft 4.

It should be noted that the workpiece positioning unit 2 further includes a mounting seat 23, and the driving mechanism 213 is connected to the base 1 through the mounting seat 23. In this way, the driving mechanism 213 can drive the upper clamp 212 to move relative to the base 1, and the lower clamp 211 is connected to the base 1, so that the upper clamp 212 can move relative to the lower clamp 211, and the upper clamp 212 can move toward or away from the lower clamp 211 by reciprocating.

Alternatively, the driving mechanism 213 is an air cylinder or an electric cylinder. The cylinder is a cylindrical metal mechanism that guides the piston to perform linear reciprocating motion in the cylinder. The electric cylinder is a mechanism that integrates a servo motor and a lead screw, and converts the rotational motion of the servo motor into linear motion. The driving mechanism 213 drives the upper clamp 212 to perform linear reciprocating motion through the linear reciprocating motion of the output end of the driving mechanism, so that the upper clamp 212 is close to or far away from the lower clamp 211.

Specifically, the base 1 is provided with a rear baffle 11, and one side of the positioning groove 22 far away from the motor shaft limiting hole 331 faces the rear baffle 11. After the positioning plate 31 presses the front end of the motor shaft 4, the drilling shaft or the tapping screw tap 5 passes through the positioning hole 34 and applies force to the front end of the motor shaft 4 to realize tapping, at this time, the motor shaft 4 tends to move towards the direction of the side, away from the motor shaft limiting hole 331, of the positioning groove 22, the rear baffle plate 11 can be used for preventing the motor shaft 4 from moving, and therefore the drilling shaft or the tapping screw tap 5 can be used for tapping at the front end of the motor shaft 4.
