Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a swing lifting body capable of controlling an angle. Background Art

[0002] A lifting body is a device or equipment that can realize the lifting function in a certain way. It has a wide range of applications in many fields. It is usually driven by electric, hydraulic or other power methods to realize the lifting and positioning of objects. At present, some lifting bodies on the market use a motor to drive the lead screw to rotate, and the lead screw pushes the output shaft forward to realize the lifting and lowering of the processing parts. The processing parts are welding guns, cutters or fixtures. However, the output shaft of the lifting body is often unable to rotate, lacks the angle adjustment function, and cannot adapt to some multi-angle processing occasions; and in order to ensure the elongation range of the lifting body, the output shaft of the lifting body is hollowed, and the lead screw can extend into the lifting body, so that the lead screw can be made very long, and the output shaft can also increase the elongation range, but the lead screw is located at one end of the output shaft. Lack of positioning, if one end of the lead screw is fixed and the other end is suspended, a cantilever beam structure will be formed. When subjected to external forces (such as cutting force, friction, gravity, etc.), the cantilever part will be subjected to bending moment, causing the lead screw to bend, thereby affecting the normal operation of the lifting body.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-9As shown, a swing lifting body capable of controlling an angle includes a base 1, a shell 2, a screw body 5 and an output shaft body 6, the output shaft body 6 is hollow in design, the lifting body also includes a supporting mechanism 20, a first motor 3 is bolted to one side of the base 1, a coupling 4 is fixed to the output shaft of the first motor 3, and the other end of the coupling 4 is fixed to the screw body 5, a moving seat 7 is arranged on the inner side of the base 1, a threaded sleeve 8 is slidably arranged on the inner wall of the moving seat 7, and the threaded sleeve 8 is threadedly connected to the surface of the screw body 5, a compression spring 9 is fixed to one side of the threaded sleeve 8, and the other end of the compression spring 9 is fixed to the inner wall of the moving seat 7 A first micro switch 10 is also provided on the inner wall of the movable seat 7, and the spring end of the first micro switch 10 contacts with the threaded sleeve 8. A vertical plate 13 is bolted to the surface of the movable seat 7, and a second motor 14 is bolted to the surface of the vertical plate 13. The second motor 14 is a stepping motor. A first gear 15 is fixed to the output shaft of the second motor 14, and a second gear 16 is also fixed to the surface of the output shaft body 6, and the first gear 15 and the second gear 16 are fixed to each other. A first bearing 12 is also fixed to the surface of the movable seat 7, and the output shaft body 6 and the inner ring of the first bearing 12 are fixed to each other, so that the output shaft body 6 can rotate with the surface of the movable seat 7.

[0028] The supporting mechanism 20 includes a ferrule 201, a second bearing 202 and a slider 203. The ferrule 201 is slidably connected to the inner wall of the output shaft body 6. Long grooves 204 are provided on the upper and lower sides of the inner wall of the output shaft body 6. The slider 203 is welded to the surface of the ferrule 201 and is slidably connected to the inner wall of the long groove 204. The second bearing 202 is fixed to the inner side of the ferrule 201, and the end of the screw body 5 away from the coupling 4 is fixed to the inner ring of the second bearing 202. The length of the long groove 204 is less than the length of the screw body 5. When using the lifting body, the tool or welding gun is fixed to the output shaft body 6, and then the first motor 3 is turned on, and its output shaft rotates, which then drives the coupling 4 and the screw body 5 to rotate, which causes the threaded sleeve 8 to open The movable seat 7 starts to move, and the compression spring 9 is used to push the movable seat 7 to move. Since the movable seat 7 is descending downward, the threaded sleeve 8 can easily push the movable seat 7 to descend through the compression spring 9, and the first micro switch 10 will not be triggered. The two inner sides of the base 1 are bolted with movable columns 17. Both sides of the surface of the movable seat 7 are penetrated by a slide groove 11. The inner wall of the slide groove 11 is slidably connected with the surface of the movable column 17. The movable seat 7 can move along the surface of the movable column 17 through the slide groove 11 during the process, thereby increasing the running stability of the movable seat 7. The movable seat 7 pushes the output shaft body 6 to extend through the first bearing 12, so that the output shaft body 6 descends, thereby driving the processing parts such as the tool or welding gun fixed on the surface to descend for processing;

[0029] If the angle of the processing part needs to be changed, the second motor 14 can be turned on. The output shaft of the second motor 14 rotates through the first gear 15 and the second gear 16 to drive the output shaft body 6 to rotate, and adjust the angle of the processing part on the output shaft to adapt to processing at different angles. The blade direction can coincide with the cutting direction, such as used in engraving, cloth cutting, leather cutting, etc., and the welding direction can be perpendicular to the cutting direction, such as welding, welding, etc.; after the processing part hits the workpiece, the extension of the output shaft body 6 is resisted, which causes the moving seat 7 to be resisted, and the threaded sleeve 8 pushes the compression spring 9 to be further compressed, and squeezes the spring of the first microswitch 10, so that the first microswitch 10 is turned on, and then the first motor 3 is turned off to stop the output shaft of the output shaft body 6 from extending to prevent excessive squeezing of the workpiece.

[0030] A second microswitch 18 and a third microswitch 19 are bolted to both sides of the lower part of the base 1. The first microswitch 10, the second microswitch 18 and the third microswitch 19 are electrically connected to the first motor 3 through a programmable PLC controller. When the output shaft body 6 is extended to the extreme, the moving seat 7 can also touch the spring of the third microswitch 19 and squeeze it, so that the third microswitch 19 is turned on, and the first motor 3 is turned off through the PLC controller to stop the output shaft body 6 from extending. When the output shaft body 6 is contracted to the extreme, the moving seat 7 can also touch the spring of the second microswitch 18 and squeeze it, so that the first motor 3 stops, thereby achieving the effect of limiting the up and down movement range of the output shaft body 6.

[0031] During the extension or contraction of the output shaft body 6, the output shaft body 6 can move along the surface of the slider 203 through the long groove 204, so that the output shaft body 6 will not drive the ring 201 to move together during the movement, and the ring 201 will not affect the extension or contraction of the output shaft body 6. At the same time, the screw body 5 can rotate with the ring 201 through the second bearing 202. During the rotation of the output shaft body 6, although the ring 201 can be driven to rotate through the long groove 204 and the slider 203, under the action of the second bearing 202, the rotation of the screw body 5 will not be affected. Moreover, the coordinated use of the ring 201, the second bearing 202, the slider 203 and the long groove 204 can not only provide a support point for the other end of the screw body 5, but also prevent the rotation and movement of the output shaft body 6 from affecting the screw body 5, thereby ensuring that the lifting body itself can operate normally; the moving seat 7 is designed to be wide at the top and narrow at the bottom to prevent the moving seat 7 from colliding with the second microswitch 18 or the third microswitch 19 itself during the movement.
