and the locking mechanism is arranged on the base 4 and is used for limiting the radial rotation of the two workpieces.
The invention can be used in the processing of the external teeth of the star wheel of a star wheel gearbox to fix the star wheels, when the star wheel gearbox is particularly used, the device can be firstly installed on a workbench of a slotting machine, a pressing plate 8 is detached, two star wheels are sleeved on a centering ring 7 in sequence, and referring to fig. 7, the two star wheels are overlapped up and down on the centering ring 7, the star wheel at the lower side is supported by a backing plate 6, the end face of the star wheel at the upper side can be slightly higher than the upper end face of the centering ring 7, at the moment, a locking mechanism is controlled to limit the installation grooves of the inner walls of the two star wheels, radial displacement of the star wheels is limited in the processing process through the locking mechanism, finally, the pressing plate 8 is fixed on the end face of the star wheel at the upper side, and the backing plate 6 and the pressing plate 8 are positioned in the axial direction, so that the star wheels are fixed on the device, and the gear shaping processing of the two star wheels can be performed. In order to avoid the contact between the cutter and the backing plate 6, a yielding gap is formed in the upper portion of the backing plate 6, and the yielding gap 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 contact with the inner wall of the workpiece. The positioning block 71 is matched with the square groove on the inner wall of the star wheel (the positioning block 71 is abutted against the groove wall of the square groove), and the radial positioning of the star wheel can be realized 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 section of the positioning block 71 can be T-shaped, and the positioning block 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 star wheel positioned below, one positioning block corresponds to the inner wall of the star wheel positioned above, and the two positioning blocks can be overlapped up and down.
The locking mechanism 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 in contact with the inner wall of a workpiece, as shown in fig. 2 and 4. A specific driving member 9 may comprise a pin pulling rod 91, wherein the pin pulling rod 91 is installed in the base 4, and one 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 poking blocks 92 are arranged on the poking pin rods 91 positioned on the centering rings 7, the poking blocks are arranged on the poking pin rods 91 in a vertical side-by-side mode, and poking pieces are arranged on the poking blocks 92; the handle 93, one end of the handle 93 is connected with the pin pulling rod 91 in the cavity of the base 4, the other end extends out of the base 4, and a strip-shaped groove communicated with the cavity is formed in the base 4 and used for the handle 93 to move in the strip-shaped groove; the pin pulling rod 91 in this embodiment is rotatably mounted in the base 4.
The locking member 10 may comprise a seat 101 fixed to said centering ring 7; the two lock pins 102 are movably arranged in the support 101, the head end and the tail end of each lock pin 102 extend out of the support 101, a locking head 103 is arranged at the head end of each lock pin 102, an acute angle is formed between the axis of each locking head 103 and the tangent line of the inner wall of a workpiece, a stirring block 104 is arranged at the tail end of each lock pin 102, and the stirring block 104 is controlled by the stirring piece to reciprocate; and an elastic support member mounted on the support 101 at the rear end of the locking pin 102 for supporting the locking pin 102.
When the locking mechanism is operated, the pulling pin rod 91 is controlled to rotate by the plate-moving handle 93, the pulling block 92 is driven to rotate, the pulling piece on the pulling block 92 drives the lock pin 102 to reciprocate, if the star wheel is processed, the pulling piece drives the lock pin 102 to extend out of the support 101, and referring to fig. 6, the locking head 103 is propped against the inner wall of the star wheel and keeps the state until the external tooth inserting operation is completed, and the force of pulling the handle 93 can be reduced because the lock pin 102 is supported by the elastic supporting piece. If the star wheel is to be removed, the toggle member drives the lock pin 102 to retract into the support 101, and the lock pin 102 is kept with a moving supporting force by the elastic support member during the retraction 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 forms an acute angle with the tangent line of the inner wall of the workpiece, the locking head 103 can lean against the inner wall of the star wheel, and the locking effect on the star wheel is better.
The stirring piece comprises a stirring claw 94 and a stirring rod 95, referring to fig. 4, the stirring claw 94 and the stirring rod 95 are arranged at intervals, and the stirring block 104 is positioned between the stirring rod 95 and the stirring claw 94. The poking claw 94 can enable the poking block 104 to retreat, the lock pin 102 is retracted, the poking rod 95 can push the poking block 104 to advance, the lock pin 102 stretches out, and the poking piece can also adopt a poking fork in the existing gear shifting mechanism to poke the block 104 through the poking fork.
When the star wheel is processed, in order to avoid separation between the locking head 103 and the inner wall of the star wheel, the handle 93 can be locked, for example, a hole is formed in the handle 93, a bolt is inserted into the hole formed in the chassis 5 through the hole, a limit pusher dog can be arranged on the shifting block 92, the direction of the limit pusher dog is opposite to that of the pusher dog 94, and the limit pusher dog is locked in a locking groove formed in the centering ring 7.
The elastic supporting piece comprises a sleeve 105, referring to fig. 4, one end of the sleeve 105 is installed on a support 101 positioned at the tail end of a lock pin 102 and used for accommodating the tail end of the lock pin 102, and an open slot for moving a poking block 104 is formed in the sleeve 105; spring seat 106, spring seat 106 is installed in the other end of sleeve 105, is connected with the spring between spring seat 106 and the tail end of lockpin 102. The spring supports the lock pin 102, so that the lock pin 102 can be kept to have a supporting force for retreating movement, the impact of the lock pin 102 is avoided, and the force for pulling the handle 93 can be reduced.
Referring to fig. 5, an arc-shaped positioning protrusion 73 is provided on the outer wall of the centering ring 7, and the positioning protrusion 73 contacts with the groove top of the mounting groove on the inner wall of the star wheel, so that the radial rotation of the star wheel in the processing process can be further prevented.
