Description

Induction amplifier of clutch mechanism

The invention relates to the sensing of the machine tool, in particular to the clutch mechanism sensing technology of the spindle of the machine tool, in particular to the induction amplifying device of the clutch mechanism.

Please refer to the figure 7~9. The power switching of the conventional machine tool spindle assembly 900 can be achieved with the clutch mechanism 800. The clutch mechanism 800 utilizes the upper and lower curved teeth devices 810 and 820 (Figs. 8 and 9), and the selective engagement and separation are used as technical means. In order to obtain the meshing and disengaging states of the upper and lower curved teeth devices 810 and 820, the clutch mechanism 800 still needs to cooperate with a lever group 910 and a sensing group 920. The lever group 910 and the sensing group 920 are respectively disposed in the cast iron 901 of the spindle assembly 900 and at the outer preset position. Among them, the cast iron 901 is formed with a vertically connected one-class hole 902 and a long slot 903.

The above-mentioned lever set 910 includes a push rod 911, an elastic member 912 and a lever 913. The push rod 911 and the elastic member 912 are accommodated in the class hole 902, and one end of the push rod 911 protrudes from the class hole 902 and is pressed against the lower curved tooth device 820. The lever 913 is accommodated in the long slot 903, and one end is perpendicularly connected to the push rod 911, and the other end protrudes from the long slot 903. When the upper and lower curved teeth devices 810, 820 move, the linkage push rod The 911 is displaced by the traction lever 913.

The sensing group 920 includes a plurality of symmetrically disposed limit switches 921, 921', and the reeds 922, 922' of the limit switches 921, 921' are selectively pressed by the lever 913, and the lever 913 is pressed. At different positions, the reeds 922, 922' of the relative position limit switches 921, 921' are pressed to cause the limit switches 921, 921' to output an actuation signal, thereby actuating the state of the upper and lower curved devices 810, 820.

For example, when the clutch mechanism 800 is above the clutch mechanism 800 and the lower crank device 810, 820 is in the separated state, the lower crank device 820 is pushed to push the push rod 911, so that the push rod 911 compresses the elastic member 912, and the lever 913 is linked. The upper displacement is pressed against the reed 922 of the first position limit switch 921, and the trigger limit switch 921 outputs an actuation signal. On the contrary, when the clutch mechanism 800 and the lower crank device 810, 820 are in the meshing state, the lower crank device 820 cannot push the push rod 911, and the push rod 911 is reversely pressed by the elastic member 912, and is connected. The rod 913 is displaced downward, pressed against the reed 922' of the second position limit switch 921', and the trigger limit switches 921, 921' output an actuation signal (as shown in Fig. 8).

Conventionally, the first and second position limit switches 921, 921' are triggered to output an actuation signal to transmit the state (engagement or separation) of the upper and lower crank means 810, 820 of the clutch mechanism 800, and there are many defects. For example, the limit switches 921, 921' are mechanical components, and must depend on a certain stroke to push the reeds 922, 922', but the displacement of the lever set 910 is only 1 to 1 reaction of the upper and lower curved devices 810. , 820 meshing or separating the amount of displacement, The displacement amount is only about the height A of the crown and the valley of the upper and lower curved teeth devices 810 and 820. It can be seen that the displacement amount of the lever 913 is very small. The reeds 922, 922' themselves have a certain amount of physical deformation, plus the principle of the action lever and the length of the force arm, there will be a certain amount of deformation directly or indirectly, the amount of deformation will directly offset the upper and lower The amount of displacement of the meandering devices 810, 820 that are engaged or disengaged is such that the amount of displacement that has been slightly insufficient is further insufficient, directly affecting the sensitivity of the reaction of the mechanical limit switches 921, 921'. This causes the user to frequently check and adjust the reeds 922, 922' of the limit switches 921, 921' to ensure that the lever 913 can smoothly push the reeds 922, 922' and trigger the limit switch 921.

Moreover, the displacement amount limited by the clutch mechanism 800 and the set of the levers 910 transmitting the displacement amount can only be transmitted by 1 to 1, so that the sensing group 920 is often prevented from being touched by the set 910. The smooth triggering causes troubles and troubles in the actuation state of the clutch mechanism 800.

In view of the above problems and deficiencies of the prior art, the main object of the present invention is to provide an inductive amplifying device for a clutch mechanism. In order to solve the problem that the conventional lever group can only transmit 1 to 1 displacement, it is impossible to amplify the very small meshing displacement, and the mechanical limit switch uses the amount of deformation to more or less the offset amount.

According to the above object of the present invention, an inductive amplifying device for a clutch mechanism is provided, comprising a pivoting seat set, a plurality of sensing members and a swinging member. Pivot socket The pivoting piece includes a plurality of symmetrically disposed pivoting plates, and each pivoting piece is symmetrically disposed with a pivot hole and a slotted hole, and the pivot hole is pivotally connected to a pivot. Each of the sensing members is respectively disposed in the slotted hole. The oscillating member has a through hole and a through hole at one end, at least one fin formed at the other end, and the through hole provides a pivotal penetration, so that the oscillating member is pivotally pivoted to selectively form a swing, and the flap is interlocked Trigger one of the sensing members. When the clutch mechanism is implemented in the clutch mechanism, the swinging member is pivotally connected to the lever group in the clutch mechanism, and the clutch mechanism transmits the clutch mechanism to the swinging member, and the swinging member converts the swinging member into a yaw state by a pivot. And using the arm distance formed between the pivot and the end of the airfoil, further amplifying the yaw distance (displacement amount), so that the airfoil forms a predetermined amplitude swing.

The above-mentioned lever set 930 includes a push rod 931, an elastic member 932, a bolt 933 and a lever 934. The push rod 931, the elastic member 932 and the bolt 933 are sequentially accommodated in the class hole 712, and one end of the push rod 931 protrudes from the class hole 712 and is pressed against the lower curved tooth device 720. The lever 934 is received in the long slot 713, and one end is perpendicularly connected to the push rod 931, and the other end protrudes from the long slot 713. Upper and lower curved teeth When the 710 and 720 are in motion, the push rod 931 is interlocked and the traction lever 934 is displaced.

In addition, the inductive amplifying device of the clutch mechanism of the present invention comprises a pivoting base set 100, a plurality of sensing members 300, a swinging member 400 and a protective cover 500, wherein:

The pivoting base set 100 includes a plurality of pivoting pieces 110, a plurality of locking pieces 120 and a pivot 130. Each of the pivoting pieces 110 includes a pivot hole 111, and each of the locking pieces 120 includes a slotted hole 121. Each of the pivoting pieces 110 is symmetrically disposed, and a pivot hole 111 is formed in each of the pivoting pieces 110 to provide a pivot 130 to pass through the pivot holes 111. Each of the locking pieces 120 is disposed corresponding to each of the pivoting pieces 110, and a slot-shaped hole 121 is formed in each of the locking pieces 120. In addition, when the locking piece 120 and the pivoting piece 110 are implemented, they can be selectively integrated into a single pivoting piece as an embodiment (not shown), which facilitates different embodiments and simplifies the components.

The sensing members 300, 300' are respectively disposed corresponding to the slot-shaped holes 121 of the locking pieces 120, and the sensing members 300, 300' are disposed at the first position and the second position of different heights, and each sensing The pieces 300, 300' can selectively adopt a light-shielding sensing member and are triggered to transmit an actuation signal.

The swinging member 400 includes a through hole 410, a through hole 420 and at least one fin 430. The through hole 410 and the through hole 420 are respectively formed at one end of the swinging member 400, and the through hole 410 is perpendicular to the axis of the through hole 420, and the other end of the swinging member 400 is formed with at least one fin 430, and the end of the wing piece 430 is spaced apart from the through hole 410, having A preset length distance (arm distance). The pivot 130 extends through the through hole 410 of the swinging member 400, so that the swinging member 400 is movably pivoted between the pivoting pieces 110, and the through hole is 420 is that one end of the lever 934 of the lever group 930 is pivotally connected and is tilted to selectively swing the swinging member 400, and the interlocking flap 430 triggers the sensors 300, 300'.

When the clutch mechanism 700 is actuated, when the clutch mechanism 700 is above and the lower crank device 710, 720 is in the separated state, the lower crank device 720 pushes the push rod 931 to compress the push rod 931. The elastic member 932 is displaced upwardly by the lever 934, so that the lever 934 pushes up the swinging member 400, and the swinging member 400 is yawed with the pivot 130 as an axis, so that the other end flap 430 faces the first position. The sensing component 300 in the first position is moved, and the sensing component 300 in the first position is triggered to output an actuation signal. (as shown in Figures 3 and 4)

On the contrary, when the upper and lower crank means 710, 720 are in the engaged state, the lower curved device 720 is lowered and the pusher 931 is no longer pushed, and the pusher 931 is reversely displaced by the elastic member 932. And the linkage lever 934 is displaced downward to press against the swinging member 400. At this time, the swinging member 400 is yawed with the pivot 130 as an axis, and the flap 430 of the swinging member 400 is moved toward the second position. The sensing member 300' located at the second position is blocked, and the sensing member 300' located at the second position is triggered to output an actuation signal. (as shown in Figures 5 and 6)

In summary, the operating distance of the clutch mechanism 700 to engage or disengage, although only the heights A of the upper and lower curved teeth devices 710, 720 crowns and valleys (Fig. 9), can be separated by the structure of the present invention. The displacement of the mechanism 700 is converted into a yaw form, and the arm distance formed between the pivot 130 and the end of the flap 430 is used. This yaw distance (distance) is amplified in one step, so that the flap 430 forms a swing of a predetermined amplitude. Further, the non-contact triggering of each of the sensing members 300, 300' enables the sensing members 300, 300' to reliably react to the operating state of the clutch mechanism 700, thereby solving the problem of the use of the conventional limit switch.
