When the drill bit to be clamped is inserted into the tool apron 2 in use, at the moment, the elastic positioning mechanism is triggered to limit one end of the drill bit inserted into the tool apron 2, so that the drill bit and the Morse taper shank 1 are kept in a coaxial state;
the movement amount of the elastic positioning mechanism is related to the thickness of a drill bit inserted into the tool apron 2, the thicker the drill bit is, the larger the movement amount of the elastic positioning mechanism is, when the thickness of the drill bit exceeds a certain range (namely, the movement amount of the elastic positioning mechanism exceeds a corresponding range), the elastic driven mechanism triggers movement and drives the transmission sleeve mechanism to drive the mounting frame 8 to rotate, so that the clamping piece 9 with a larger size on the mounting frame 8 corresponds to the drill bit, when the power mechanism moves, the clamping piece 9 corresponding to the drill bit can move along the radial direction of the tool apron 2, the clamping of the drill bit is completed, the automatic adjustment and replacement of the clamping piece 9 according to the thickness of the drill bit is realized, the contact position of the clamping piece 9 and the drill bit is effectively improved, and further, the friction force between the clamping piece 9 and the drill bit is greatly improved, and therefore, the stability of clamping the drill bit is remarkably improved.

Referring to fig. 7 and 11 again, a plurality of cross plates 13 are circumferentially and equidistantly mounted on the outer wall of the tool holder 2, the power mechanism comprises a screw assembly mounted on the cross plates 13 and a driving assembly connected with the screw assembly, the driving assembly comprises a rotating ring 21 rotatably mounted on the outer periphery of the tool holder 2 and a first gear 20 rotatably mounted at the bottom of the cross plates 13, and teeth meshed with the first gear 20 are arranged on the inner wall of the rotating ring 21.

Specifically, the traversing plate 18 is provided with three through holes for the penetration of the screw rod 16 and the two guide rods 17, and the inner wall of the through hole penetrated by the screw rod 16 is provided with threads engaged with the screw rod 16;
next, the bevel gear set 19 includes a first bevel gear coaxially mounted with the first gear 20 and a second bevel gear mounted on the screw 16, and the second bevel gear is engaged with the first bevel gear.
When the drill bit to be clamped is inserted into the tool holder 2, a worker rotates the rotary ring 21 forward, so that teeth on the inner wall of the rotary ring 21 drive the first gear 20 to rotate, the rotating shaft of the first gear 20 drives the screw rod 16 to rotate through the bevel gear group 19, correspondingly, the two guide rods 17 guide the traversing plate 18, the traversing plate 18 is in threaded fit with the screw rod 16 to gradually move towards the tool holder 2, and meanwhile, the traversing plate 18 drives the mounting frame 8 to do linear motion along the radial direction of the tool holder 2 through the transmission sleeve mechanism, so that the clamping piece 9 corresponding to the drill bit performs clamping and fixing actions on the drill bit;
conversely, when the operator needs to take down the drill bit for maintenance, the rotating ring 21 is reversely rotated, so that the traverse plate 18 is in threaded engagement with the screw rod 16 and gradually moves towards a direction away from the tool apron 2, and accordingly, the mounting frame 8 drives the clamping member 9 to gradually move away from the drill bit, so that the clamping state of the drill bit is relieved.
Referring to fig. 10 and 11 again, the driving engagement mechanism includes a protruding block 30 mounted on the traverse plate 18, a rotating shaft 11 rotatably mounted on a side of the protruding block 30 facing the tool holder 2, and a driving tube 12 rotatably mounted on the tool holder 2, and the mounting frame 8 is fixed on an end of the rotating shaft 11 away from the protruding block 30;

When the elastic driven mechanism is matched with the elastic positioning mechanism and triggers movement (namely, the thickness of the drill bit inserted into the tool apron 2 exceeds a certain range), the elastic driven mechanism drives the driving pipe 12 to rotate, and then the driving pipe 12 drives the rotating shaft 11 to rotate through the strip-shaped groove 15 on the inner wall of the driving pipe and the strip-shaped bulge 14 on the outer wall of the rotating shaft 11, and then the rotating shaft 11 drives the mounting frame 8 to rotate, so that the clamping piece 9 automatically adjusts and changes according to the thickness of the drill bit, the contact part between the clamping piece 9 and the drill bit is effectively improved, and further, the friction force between the clamping piece 9 and the drill bit is greatly improved, and the stability of clamping the drill bit is remarkably improved;
when clamping operation is performed (i.e. when a worker rotates the rotating ring 21 forward), the rotating shaft 11 gradually moves towards the tool apron 2 and slides relative to the driving tube 12, so that the arrangement of the strip-shaped protrusions 14 and the strip-shaped grooves 15 ensures that the transmission connection state of the elastic driven mechanism to the rotating shaft 11 can be maintained when the rotating shaft 11 is at different positions.
Referring to fig. 6 again, the elastic positioning mechanism includes a cross bar 6 slidably disposed in the tool holder 2, a positioning member 3 mounted on one end of the cross bar 6 in the tool holder 2, and a first cylindrical spring 7 sleeved on the outer periphery of the cross bar 6, where the positioning member 3 is provided with an inclined surface 4 and an end surface 5;
the cross rod 6 is perpendicular to the central axis of the tool apron 2, one end of the cross rod 6, far away from the locating piece 3, extends out of the tool apron 2 and is connected with the elastic driven mechanism, one end of the first cylindrical spring 7 is connected with the locating piece 3, and the other end of the first cylindrical spring is connected with the inner wall of the tool apron 2.
When the drill bit is inserted into the tool apron 2, the end part of the drill bit is firstly contacted with the inclined surface 4 on the positioning piece 3, the positioning piece 3 is in abdication along with the continuous extension of the drill bit, the end surface 5 on the positioning piece 3 is finally abutted with the drill bit, the positioning piece 3 drives the cross rod 6 to gradually slide towards the outside of the tool apron 2 in the abdication process, and the first cylindrical spring 7 is compressed, so that the pre-clamping function of the positioning piece 3 on the drill bit is finally realized under the elastic action of the first cylindrical spring 7, the drill bit and the Morse taper shank 1 are ensured to keep a coaxial state, and the inclined surface 4 is arranged to play a foolproof role, so that the operation of a worker during clamping the drill bit is facilitated.
Referring to fig. 5 and 8 again, the elastic driven mechanism includes a driven plate 27 movably disposed on the outer wall of the tool holder 2, and a pulley 25 rotatably mounted on one end of the cross bar 6 away from the positioning member 3, the driven plate 27 is connected with an energy storage structure mounted on the outer wall of the tool holder 2, and the energy storage structure stores elastic potential energy;
wherein the bottom of the driven plate 27 is arranged in a step shape, and is provided with a first abutting surface 31, a second abutting surface 32 and a third abutting surface 33, and the pulley 25 abuts against the first abutting surface 31;

When the positioning piece 3 drives the cross rod 6 to slide towards the outside of the tool apron 2, the pulley 25 will roll on the first abutting surface 31 first, the rolling distance of the pulley 25 is equal to the moving distance of the positioning piece 3 in the abdication, namely, the thicker the drill bit inserted into the tool apron 2 is, the larger the rolling distance of the pulley 25 is;
when the thickness of the drill bit is large and the pulley 25 is separated from the first abutting surface 31 after rolling, and then the energy storage structure releases a part of elastic potential energy, so that the driven plate 27 descends, the pulley 25 abuts against the second abutting surface 32, correspondingly, the rack plate 24 descends along with the driven plate 27 and rotates the second gear 23, then the rotation shaft of the second gear 23 drives the transmission tube 12 to rotate, and the transmission tube 12 drives the rotation shaft 11 and the mounting frame 8 to rotate (taking the drawing as an example, three clamping pieces 9 are fixed on the mounting frame 8, and therefore, 120 DEG rotation occurs to the mounting frame 8 when the driven plate 27 descends each time), and the clamping pieces 9 with larger size are replaced;
similarly, if the subsequent pulley 25 is disengaged from the second abutment surface 32, the energy storage structure will release a part of elastic potential energy again, so that the pulley 25 abuts against the third abutment surface 33, and accordingly, the mounting frame 8 rotates again, and the clamping member 9 is replaced.
The energy storage structure comprises a mounting plate 26 mounted on the outer wall of the tool apron 2, two upright posts 28 which are slidably arranged on the mounting plate 26 and one end of which is fixed with the top end of the driven plate 27, and two second cylindrical springs 29 which are respectively sleeved on the peripheries of the two upright posts 28, wherein two ends of each second cylindrical spring 29 are respectively connected with the mounting plate 26 and the driven plate 27 and are in a compressed state.
When the pulley 25 is disengaged from the first abutment surface 31, the second cylindrical spring 29 will rebound to move the driven plate 27 downward, so that the pulley 25 abuts against the second abutment surface 32, and then, if the pulley 25 continues to roll and is disengaged from the second abutment surface 32, the second cylindrical spring 29 will rebound again, so that the driven plate 27 moves downward again, and the pulley 25 abuts against the third abutment surface 33.
In practical use, when the worker needs to replace another size drill bit, if the pulley 25 is in the abutting state with the second abutting surface 32 or the third abutting surface 33, the worker needs to dial the driven plate 27 upwards first to make the first cylindrical spring 7 rebound smoothly, so as to promote the positioning member 3, the cross rod 6 and the pulley 25 to reset.
The clamping method of the drill clamping jig based on the Morse taper shank tool apron comprises the following steps:
firstly, checking whether foreign matters remain on the periphery of a drill bit to be clamped and the inside of the tool apron 2, and cleaning the foreign matters if the foreign matters exist, so as to ensure the clamping precision;
step two, the drill bit to be clamped stretches into the tool apron 2, the elastic positioning mechanism is triggered, a limiting action is performed on one end of the drill bit stretching into the tool apron 2, pre-clamping is completed, the elastic positioning mechanism is matched with the elastic driven mechanism, and if the elastic driven mechanism is matched with the elastic positioning mechanism and triggers movement, the mounting frame 8 is driven by the sleeving transmission mechanism to perform replacement action on the clamping piece 9;
thirdly, after the pre-clamping is completed, the mounting frame 8 is driven by the power mechanism to do linear motion along the radial direction of the tool apron 2, so that the clamping piece 9 corresponding to the drill bit on the mounting frame 8 performs clamping and fixing actions on the drill bit;
and fourthly, knocking one end, far away from the tool apron 2, of the Morse taper shank 1 into a corresponding mounting hole on the machine tool, wherein the Morse taper shank 1 is in interference fit with the mounting hole and is fixed through Morse taper.
