Description

Technical Field

[0001] The utility model relates to the technical field of lathe auxiliary parts, in particular to a manual-automatic feeding device. Background Art

[0002] The function of the slide box in the lathe is to convert the rotational motion transmitted by the lead screw or guide bar into linear motion, and drive the tool holder to feed, thereby realizing the fast and slow speed conversion of the tool holder movement.

[0003] The feeding device includes the aforementioned slide box. The existing feeding device usually uses a motor to drive the lead screw to rotate, and then uses the lead screw nut to cooperate with the lead screw to realize the horizontal movement of the workbench; however, in the subsequent use process, when the position of the workbench needs to be manually adjusted, it is often necessary to use a more complex structure to achieve automatic and manual switching, which is not conducive to user use.

[0045] Example:

[0046] like Figure 1-3 As shown, an embodiment of the present application discloses a manual-automatic feeding device that can realize manual and automatic switching, which is mainly used for conveying and feeding of lathes, such as longitudinal movement.

[0047] The specific structure of this application includes:

[0048] Base 1, which is an existing base structure with bolt holes provided thereon for mounting on a machine tool;

[0049] A slide track 2 is arranged on the base 1, and the slide track 2 extends along the length direction of the base 1, that is, the feed is completed by moving along the slide track 2. Preferably, the slide track 2 is two parallel tracks;

[0050] A slider 3 is slidably mounted on the slide rail 2. The slider 3 is slidably connected and can be used as a mounting platform, and a corresponding feed matching device can be installed on the top;

[0051] A drive unit 4 is installed at one end of the base 1. The drive unit 4 can be installed inside the base 1, or installed separately outside one end of the base 1. Specifically, the drive unit 4 can be a servo motor, a stepper motor, a brake motor, or a common type of motor;

[0052] The screw rod 5 is installed at the output end of the driving unit 4, and the screw rod 5 and the sliding track 2 are parallel to each other, that is, the screw rod 5 provides the trajectory and power source of the movement, and the sliding track 2 ensures that the subsequent switching motion unit 6 can stably move along it;

[0053] The switching motion unit 6 is installed on the screw rod 5, and the top of the switching motion unit 6 is connected to the bottom of the slider 3. The switching motion unit 6 is a moving main body, which can be realized manually or automatically to meet the user's multi-faceted needs.

[0054] The switching motion unit 6 is further described as follows: Figure 1 , 2 As shown, the switching motion unit 6 includes:

[0055] A box body 601, the top of which is connected to the bottom of the slider 3. The box body 601 is a cavity with an assembly space provided inside, and the top of the box body 601 can be connected to the slider 3 by bolts;

[0056] The screw rod and nut assembly 603 is installed on the screw rod 5. The screw rod and nut assembly 603 is an existing screw rod motion matching part and will not be described in detail here.

[0057] A driving gear 604 is mounted on the screw-nut assembly 603, and the driving gear 604 moves together with the screw-nut assembly 603;

[0058] A manual gear assembly 605 meshes with the driving gear 604, and the manual gear assembly 605 is installed inside the box 601;

[0059] The brake 602 is installed inside the box 601, and the brake 602 is located below the screw nut assembly 603, and the braking end of the brake 602 corresponds to the manual gear assembly 605; the brake 602 can be an electromagnetic clutch, which mainly plays a braking role to facilitate the subsequent switching, that is, to achieve switching when the subsequent driven gear is adsorbed;

[0060] The present application further explains the movement mode of the switching movement unit 6, wherein the electromagnetic clutch cooperates with the end of the screw nut assembly 603 to complete the brake lock, at which time the screw nut assembly cannot rotate, and the drive unit 4 is started, at which time the entire box 601 can move along the screw 5;

[0061] When the electromagnetic clutch is closed, the manual gear assembly 605 is manually rotated to drive the driving gear 604 to rotate, thereby driving the screw nut assembly to rotate, so that the entire box body 601 can move along the screw 5.

[0062] In one embodiment, if Figure 3 As shown, the manual gear assembly 605 includes:

[0063] The driven gear 606 is installed inside the box 601, and the driven gear 606 is meshed with the driving gear 604; the end surface of the driven gear 606 is matched and connected with the brake end of the brake 602, and can be connected by bolts;

[0064] The driven shaft 607 is installed inside the driven gear 606, and the driven shaft 607 is concentric with the clutch shaft of the brake 602, thus ensuring the stability of the entire device;

[0065] A first transmission gear 608 is mounted on an end of the driven shaft 607 away from the driven gear 606;

[0066] A second transmission gear 609 is installed inside the box 601, and the second transmission gear 609 is meshed with the first transmission gear 608;

[0069] The present application designs a manual gear assembly 605, which completes the transmission of power through multiple sets of gears that cooperate with each other. The specific assembly method of each gear is existing and will not be repeated here.

[0070] The manual gear assembly 605 further includes a hand wheel 612 , which is installed outside the box 601 , and the hand wheel 612 is connected to the fourth transmission gear 611 via a rotating shaft.

[0071] With respect to the specific movement mode of the manual gear assembly 605, the present application further explains as follows, that is, the hand wheel 612 rotates, driving the fourth transmission gear 611 coaxially assembled therewith to rotate, and the fourth transmission gear 611 is meshed with the third transmission gear 610 (the diameter of the third transmission gear 610 is smaller than the diameter of the fourth transmission gear 611). At this time, the rotation of the third transmission gear 610 drives the rotation of the second transmission gear 609 coaxial therewith, and then the second transmission gear 609 drives the first transmission gear 608 to rotate (the diameter of the first transmission gear 608 is smaller than the diameter of the second transmission gear 609), and the first transmission gear 608 drives the driven gear 606 coaxial therewith to rotate, and finally drives the driving gear 604 to rotate.

[0072] When the electromagnetic clutch is working, the driven gear is braked, and the driving gear 604 is also braked. The driving unit 4 drives the screw rod 5 to rotate, so that the switching motion unit 6 moves along the screw rod 5.

[0073] When the driving unit 4 stops, the rotation of the hand wheel 612 sequentially drives the fourth transmission gear 611, the third transmission gear 610, the second transmission gear 609, the first transmission gear 608, the driven gear 606 and the driving gear 604 to rotate, and the switching motion unit 6 moves along the screw rod 5.
