As shown in fig. 5, in the present embodiment, the lathe clamping fixture 10 suitable for the solid cylinder 60 further includes a connecting sleeve 50, and the connecting sleeve 50 is sleeved on the outer wall of the connecting body 20. In practical application, the connecting sleeve 50 is connected with a support structure such as a support base and a support frame, so as to support the lathe clamping jig 10. In this embodiment, the connecting sleeve 50 is connected to the connecting body 20 through a bearing (not shown), so that the connecting sleeve 50 is kept fixed during the rotation of the connecting body 20, thereby stably supporting and fixing the lathe clamping jig 10.
The working principle of the lathe clamping jig 10 suitable for the solid cylinder 60 is described below (please refer to fig. 1 to 10 together):
when the solid cylinder 60 is clamped, the solid cylinder 60 is firstly placed on the clamping support table 220, so that the limiting groove 630 of the chassis 620 of the solid cylinder 60 is matched with the limiting boss 222;
then, a forward current is supplied to the magnetic field generating mechanism 351 by the power supply (the "forward current" herein means a current direction opposite to that of the "reverse current" hereinafter); the forward current causes the magnetic field generating mechanism 351 to generate a magnetic field (i.e., generate an N-pole magnetic field) at a side close to the driving end 312, and at this time, the N-pole magnetic field generated by the magnetic field generating mechanism 351 forms an attraction effect on the unipolar magnet block 313 (S-pole magnet block) at the driving end 312, so that the unipolar magnet block 313 has a tendency to approach the magnetic field generating mechanism 351, thereby causing the axial link 310 to approach in the direction of the magnetic field generating mechanism 351;
when the axial link 310 approaches the magnetic field generating mechanism 351, the radial link 320 is driven to move together in the direction of approaching the magnetic field generating mechanism 351; the radial connecting rod 320 drives the movable pressing member 330 to move towards the direction close to the magnetic field generating mechanism 351; since the guide post 340 sequentially penetrates the first through hole 221 and the arc-shaped guide groove 400, the movable presser 330 moves in a direction approaching the magnetic field generating mechanism 351 along with the radial link 320, and at the same time, rotates in a forward direction (the "forward rotation" herein means a direction opposite to the "reverse rotation" hereinafter); in this process, the pressing and holding protrusion 201 of the movable pressing and holding member 330 rotates while moving to the direction approaching the magnetic field generating mechanism 351 along with the movable pressing and holding member 330 (i.e., the two pressing and holding protrusions 201 gradually approach each other from the initial state of being away from each other while rotating along with the movable pressing and holding member 330), thereby continuously approaching and finally stably pressing and holding on the chassis 620 of the solid cylinder 60; at this time, the pressing lug 201 and the clamping support platform 220 are mutually matched to form stable limit on the chassis 620 of the solid column 60;
when the pressing and holding bumps 201 are stably pressed and held on the bottom disc 620 of the solid column 60, the two pressing and holding bumps 201 are just oppositely pressed and held on two symmetrical sides of the bottom disc 620, so that a stable pressing and holding effect is formed on the solid column 60; because the solid cylinder 60 is unbalanced by the force applied in the process of machining the solid cylinder 60 when the solid cylinder 60 is machined by the lathe, the solid cylinder 60 can be always kept stable by the symmetrical pressing when the solid cylinder 60 is machined by the lathe, so that the machining stability and the machining precision are ensured;
it should be noted that, the movable pressing and holding member 330 of the present invention rotates while approaching or departing (i.e. moving up and down along the containing cavity 40) to the magnetic field generating mechanism 351, so that the two pressing and holding protrusions 201 approach or depart from each other; due to the design, after the two pressing and holding lugs 201 are far away from each other, the solid columns 60 with different diameters of the chassis 620 can be smoothly arranged on the limiting lug boss 222 of the clamping support platform 220; when the two pressing lugs 201 approach each other, the two pressing lugs 201 are finally pressed on the bottom plate 620 of the solid column 60 to form stable pressing on the bottom plate 620 of the solid column 60; moreover, no matter the thickness of the bottom plate 620 is thick or thin, the pressing and holding lug can be stably pressed and held on the bottom plate 620 of the solid column 60 finally, namely, the pressing and holding lug 201 can realize stable pressing and holding aiming at solid bodies with different thicknesses of the bottom plate 620; therefore, the lathe clamping jig 10 can be adaptively suitable for solid cylinders 60 of different specifications and models, and a set of corresponding lathe clamping jig 10 needs to be stopped and replaced without replacing one specification and model of solid cylinder 60, so that the cost of the lathe clamping jig 10 is reduced, and the machining production efficiency of the solid cylinder 60 is improved;
that is, the two pressing protrusions 201 move up and down and rotate along with the movable pressing member 330; the rotary motion can accommodate solid cylinders 60 of different diameters of the chassis 620; the lifting movement can be adapted to the different thickness of the solid columns 60 of the chassis 620; therefore, the two pressing and holding convex blocks 201 can simultaneously adapt to the solid columns 60 with different diameters and thicknesses of the chassis 620 by lifting and rotating along with the movable pressing and holding piece 330, and are completely self-adaptive, so that manual intervention operation is not needed, and an additional mechanism is not needed for adjustment;
the rotating connection end 100 is provided with a rotating avoidance groove 300, the radial connecting rod 320 extends into the rotating avoidance groove 300, and the two movable pressing pieces 330 are respectively rotatably connected with two ends of the radial connecting rod 320; thus, the rotation avoiding groove 300 avoids the radial connecting rod 320 when the movable pressing and holding member 330 rotates, and ensures that the movable pressing and holding member 330 flexibly and stably rotates in the forward direction and the reverse direction (i.e. reciprocating rotation);
moreover, the middle part of the radial link 320 is rotatably connected with the axial connecting end 311 of the axial link 310, i.e. the radial link 320 and the axial link 310 cooperate to form a rocker structure; the rocker structure is matched with the motion track of the movable pressing piece 330, the bottom 620 of the solid column 60 is pressed by the pressing lug 201, and if the thickness of the bottom 620 is inconsistent (namely the thickness of the bottom 620 pressed by the two pressing lugs 201 is inconsistent), the two pressing lugs 201 are self-adaptively adjusted by the rocker principle, so that the two pressing lugs 201 can be always stably and symmetrically pressed on the bottom 620, and the situation that only one pressing lug 201 presses the bottom 620 due to the inconsistent thickness of different parts of the bottom 620 is avoided;
it should be noted that, the radial link 320 is designed: on one hand, the radial link 320 drives the two movable pressing members 330 to reciprocate along the extending direction of the accommodating cavity 40 (i.e., to move up and down along the accommodating cavity 40), so as to drive the two movable pressing members 330 to reciprocate along the extending direction of the accommodating cavity 40 (i.e., to move up and down along the clamping support platform 220); on the other hand, the radial link 320 is engaged with the rotation avoidance groove 300 of the movable pressing member 330, and when the movable pressing member 330 is driven to move up and down and rotate, the rotation of the movable pressing member 330 is avoided; if the axial connecting rod 310 is directly connected with the movable pressing and holding member 330, there is no way to drive the movable pressing and holding member 330 to do lifting movement and to do rotating movement, which is a smart design of the movable pressing and holding member 330; on the other hand, the radial connecting rod 320 and the axial connecting rod 310 are matched to form a rocker structure, and the two pressing protrusions 201 are adaptively adjusted according to the rocker principle, so that the two pressing protrusions 201 can be always stably and symmetrically pressed on the chassis 620, and the situation that only one pressing protrusion 201 presses the chassis 620 due to different thicknesses of different parts of the chassis 620 is avoided;
it should be noted that the present invention controls the pressing of the movable pressing member 330 on the bottom plate 620 of the solid cylinder 60 by magnetic force; here, the magnetic force control is a flexible control; the damage to the solid cylinder 60 in the clamping process is reduced to the greatest extent by a flexible control mode; moreover, the driving end 312 and the magnetic field generating mechanism 351 are driven in a non-contact manner, so that rigid mechanical collision is avoided, mechanical abrasion is avoided, further damage to the lathe clamping jig 10 is greatly reduced, and the service life of the lathe clamping jig 10 is prolonged; furthermore, the pressing and holding mode of the chassis 620 of the solid cylinder 60 is realized through magnetic control, so that the pressing and holding lug 201 can be ensured to be always kept firmly pressed and held on the chassis 620 of the solid cylinder 60, and the problems of looseness and infirm clamping of the solid cylinder 60 caused by the conditions that the movable pressing and holding piece 330, the clamping support table 220 and the like are worn and the like after long-time use are avoided; the existing fixture has the problems of abrasion, deformation and the like after being used for a long time through a rigid mechanical pressing mode, so that the problems of looseness, untight clamping and the like of clamping the solid cylinder 60 occur;
when one solid cylinder 60 needs to be processed and the next solid cylinder 60 needs to be replaced, a reverse current is provided for the magnetic field generating mechanism 351 through the power supply; the reverse current causes the magnetic field generating mechanism 351 to generate a magnetic field (i.e., generate an S-pole magnetic field) at a side close to the driving end 312, and at this time, the S-pole magnetic field generated by the magnetic field generating mechanism 351 forms a repulsive action on the unipolar magnet block 313 (S-pole magnet block) at the driving end 312, so that the unipolar magnet block 313 has a tendency to move away from the magnetic field generating mechanism 351, thereby moving the axial link 310 away from the magnetic field generating mechanism 351;
when the axial link 310 moves away from the magnetic field generating mechanism 351, the radial link 320 is driven to move together in the direction away from the magnetic field generating mechanism 351; the radial connecting rod 320 drives the movable pressing member 330 to move in a direction away from the magnetic field generating mechanism 351; since the guiding post 340 sequentially penetrates the first through hole 221 and the arc-shaped guiding groove 400, the movable pressing member 330 moves in a direction away from the magnetic field generating mechanism 351 along with the radial link 320 and also reversely rotates; in this process, the pressing protrusion 201 of the movable pressing member 330 moves away from the magnetic field generating mechanism 351 while following the movable pressing member 330, and rotates in the opposite direction (i.e., the two pressing protrusions 201 gradually move away from each other and the bottom plate 620 of the solid cylinder 60 from the pressing state close to each other while following the movable pressing member 330 to rotate in the opposite direction), thereby continuously moving away from the bottom plate 620 of the solid cylinder 60; when the two pressing lugs 201 are far away from each other and are separated from the bottom plate 620 of the solid column 60, the solid column 60 is taken down; at this time, the two pressing and holding bumps 201 are away from each other to remove and remount the solid column 60 to form avoidance, so that the solid column 60 with the larger diameter of the chassis 620 can be smoothly removed from or mounted on the clamping support platform 220;
in addition, the axial connecting rod 310 and the connecting body 20 are linked through the one-to-one corresponding clamping of the limiting clamping grooves 411 and the clamping convex strips 314; when the solid cylinder 60 is processed, the driving motor drives the connecting body 20 to rotate through the transmission gear 210, so as to drive the solid cylinder 60 to rotate; in the process of rotating the connecting body 20, the movable pressing member 330 and the guiding post 340 are inevitably driven to rotate together; at this time, in order to ensure the normal operation of the lathe clamping jig 10, the axial link 310 and the radial link 320 must rotate synchronously with the movable pressing piece 330 and the guide post 340; if the axial connecting rod 310 and the radial connecting rod 320 are driven to rotate by the rotation of the movable pressing member 330, the axial connecting rod 310 and the radial connecting rod 320 cannot rotate synchronously with the movable pressing member 330; because the rotation connecting end 100 of the movable pressing and holding member 330 is provided with the rotation avoiding groove 300, the front axial connecting rod 310 and the radial connecting rod 320 rotated by the movable pressing and holding member 330 are kept static; therefore, in order to ensure that the axial connecting rod 310, the radial connecting rod 320, the movable pressing and holding part 330 and the like keep strict synchronous rotation, the connecting body 20 directly drives the axial connecting rod 310 to synchronously rotate in the rotating process through the clamping connection of the limiting clamping groove 411 and the clamping convex strip 314, so that the radial connecting rod 320 is indirectly driven to synchronously rotate; due to the design, on one hand, synchronous rotation of the connecting body 20, the movable pressing piece 330, the axial connecting rod 310 and the radial connecting rod 320 is ensured, and on the other hand, an additional driving source is not required to be added to drive the axial connecting rod 310 and the radial connecting rod 320 to rotate, so that the lathe clamping jig 10 is simple in structure and runs at high precision.
