In order to avoid the contact of the cutter and the base plate 6, the upper part of the base plate 6 is provided with a yielding notch, and the yielding notch is close to the centering ring 7.
In order to ensure the machining precision of the star wheel, referring to fig. 5, a positioning block 71 is arranged on the centering ring 7, and a positioning head 72 of the positioning block 71 extends out of the centering ring 7 to be in contact with the inner wall of the workpiece. The star wheel can be positioned by matching the positioning block 71 with the square groove of the inner wall of the star wheel (the positioning block 71 is abutted against the groove wall of the square groove), and can also be positioned in the radial direction by matching with the locking mechanism, namely the positioning block 71 and the locking mechanism can form two limiting points on the inner wall of the star wheel. The cross section of the positioning block 71 can be T-shaped and is arranged in a T-shaped groove formed in the centering ring, two positioning blocks are arranged, one positioning block corresponds to the inner wall of the lower star wheel, the other positioning block corresponds to the inner wall of the upper star wheel, and the two positioning blocks can also be overlapped up and down.
The locking mechanism of the invention comprises a driving piece 9 and a locking piece 10, wherein the driving piece 9 is arranged on the base 4, and the locking piece 10 obliquely extends out of the centering ring 7 to be contacted with the inner wall of a workpiece, as shown in figures 2 and 4. The specific driving member 9 may comprise a pin pulling rod 91, the pin pulling rod 91 is mounted in the base 4, a part of the pin pulling rod 91 is positioned in the centering ring 7, and the other part of the pin pulling rod 91 is positioned in a cavity arranged at the lower part of the base 4; the shifting blocks 92 are arranged on the pin pulling rod 91 of the centering ring 7, the two shifting blocks are arranged on the pin pulling rod 91 in a vertical parallel mode, and shifting pieces are arranged on the shifting blocks 92; one end of the handle 93 is connected with the pin pulling rod 91 in the cavity of the base 4, the other end of the handle 93 extends out of the base 4, and a strip-shaped groove communicated with the cavity is formed in the base 4 and used for enabling the handle 93 to move in the strip-shaped groove; the pin pulling lever 91 in this embodiment is rotatably mounted in the base 4.
Retaining member 10 can comprise a seat 101 fixed to said centering collar 7; the locking device comprises a locking pin 102, wherein the locking pin 102 is movably arranged in a support 101, the head end and the tail end of the locking pin 102 extend out of the support 101, a locking head 103 is arranged at the head end of the locking pin 102, an acute included angle is formed between the axis of the locking head 103 and the tangent of the inner wall of a workpiece, a toggle block 104 is arranged at the tail end of the locking pin 102, and the toggle block 104 is controlled by the toggle piece to reciprocate; and an elastic support member mounted on the seat 101 at the rear end of the locking pin 102 for supporting the locking pin 102.
When the locking mechanism is operated, the pin pulling rod 91 is controlled to rotate through the plate moving handle 93, the shifting block 92 is driven to rotate, the shifting piece on the shifting block 92 drives the lock pin 102 to reciprocate, if a star wheel is machined, the shifting piece drives the lock pin 102 to extend out of the support 101, referring to fig. 6, the locking head 103 abuts against the inner wall of the star wheel and keeps the state until the external tooth inserting operation is completed, and the elastic supporting piece supports the lock pin 102, so that the force for pulling the handle 93 can be reduced. If the star wheel needs to be removed, the poking piece drives the lock pin 102 to retreat into the support seat 101, and the elastic supporting piece keeps the lock pin 102 to have a moving supporting force in the retreating process, so that the lock pin 102 is prevented from impacting, and the locking head 103 is separated from the inner wall of the star wheel. Because the axis of the locking head 103 and the tangent line of the inner wall of the workpiece form an acute included angle, the locking head 103 can obliquely abut against the inner wall of the star wheel, and the locking effect on the star wheel is better.
