Description

Technical Field

[0001] The utility model belongs to the technical field of high-lock nut processing, and in particular relates to an automatic punching machine for high-lock nut. Background Art

[0002] High-lock nut automatic punching machines are usually pneumatically or electrically driven, and the nuts are punched through the punch head to complete the locking or other processing of the nuts.

[0003] Common high-lock nut automatic punching machines can only punch high-lock nuts of the same size when in use, which is relatively simple and cannot punch high-lock nuts of different sizes, thereby reducing the practicality of the overall device. In addition, the punching head will wear out after long-term use, and the punching head of common high-lock nut automatic punching machines is not easy to replace. In view of this, we propose a high-lock nut automatic punching machine. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic punching machine for high-lock nuts to solve the problems raised in the above background technology.

[0005] In view of this, the utility model provides a high-lock nut automatic punching machine, comprising:

[0006] A base, a U-shaped frame is fixedly installed on the top of the base, a circular groove is opened on the top of the base and on one side of the U-shaped frame, a circular disc is rotatably installed in the circular groove, a plurality of nut grooves are opened on the top of the circular disc, and a through groove is opened at the bottom of the circular groove;

[0007] A limiting component, which is located in the base and is used to limit the disc;

[0008] A hydraulic cylinder, wherein the hydraulic cylinder is fixedly mounted in a U-shaped frame, a rectangular block is fixedly mounted on the output end of the hydraulic cylinder, a rotating disk is rotatably mounted on one side of the rectangular block and directly above one of the nut slots, a plurality of punch heads are threadedly mounted on the circumference of the rotating disk, and a rotating block is fixedly mounted on the punch head;

[0009] A fixing assembly, which is located in the rectangular block and is used to fix the rotating disk;

[0010] The collecting box is inserted and installed in the base and is located at the bottom of the through slot.

[0011] In the present technical scheme, the limiting component can release the limit of the disc through the setting of the limiting component, and the personnel can first punch the size of the high lock nut according to the needs, rotate the disc, and the rotation of the disc will drive several nut slots to rotate. When the nut slot of the appropriate size is rotated to just above the through slot, the limiting component can limit the disc, and then the personnel can punch the size of the high lock nut according to the needs, and drive the rotating disk to rotate through the fixing component, and the rotation of the rotating disk drives several punching heads to rotate until the punching head of the appropriate size rotates to just above the through slot and stops. Then the personnel can put the high lock nut that needs to be punched into the nut slot above the through slot, and then start the hydraulic cylinder. The output end of the hydraulic cylinder drives the rectangular block to move downward, and the rectangular block drives the rotating disk and several punching heads to move downward. The punching head located above the through slot moves downward to punch the high lock nut, and the residue dropped by the punching will enter the collection box through the through slot, which is convenient for personnel to collect it, ensuring that the overall device can punch high lock nuts of different sizes, thereby increasing the practicality of the overall device.

[0012] By setting up the rotating block, when the punch head is worn out after long-term use, the personnel can use a wrench to clamp the rotating block on the punch head and rotate it. Under the action of the thread, the punch head can be removed from the rotating disk and replaced with a new one, ensuring that when the punch head is worn, it can be easily replaced.

[0013] In the above technical solution, further, the limit assembly includes:

[0014] A sliding groove is provided in the base and is located on one side of the disc. A plurality of limit grooves are provided on the circumferential side of the disc. A limit block is slidably installed in the sliding groove. One end of the limit block passes through one side of the sliding groove and extends into one of the limit grooves. A pull rod is fixedly installed on the other end of the limit block and is located in the sliding groove. One end of the pull rod passes through the other side of the sliding groove and extends to the outside. A spring is sleeved on the pull rod and is located in the sliding groove.

[0015] In the present technical solution, when the pull rod is pulled, the pull rod will drive the limit block to move in the sliding groove. At the same time, the movement of the limit block will also squeeze the spring to contract. When one end of the limit block moves out of one of the limit grooves, the limit block can release the limit on the disc. Then the person rotates the disc, and the rotation of the disc will drive several nut grooves to rotate. When the nut groove of the appropriate size is rotated to just above the through groove, under the action of the spring rebound force, the spring will squeeze the limit block so that one end of the limit block is inserted into the corresponding limit groove. At this time, the limit block can limit the disc, ensuring that the overall device can stamp high-locking nuts of different sizes, thereby increasing the practicality of the overall device.

[0016] In the above technical solution, further, a limiting groove at one end of the limiting block is plugged in, the limiting block is slidably connected to the base, the pull rod is slidably connected to the sliding groove and the base, and both ends of the spring are tightly welded to the limiting block and the inner wall of the sliding groove respectively.

[0020] In the present technical scheme, the five-sided plug is first pulled out from the five-sided groove one and the five-sided groove two. At this time, the five-sided plug can release the limit on the rotating disk. At this time, the personnel can rotate the rotating disk, and the rotation of the rotating disk drives several punching heads to rotate until the punching head of the appropriate size rotates to the top of the through groove and stops. Then the personnel can insert the five-sided plug into the five-sided groove one and the five-sided groove two. At this time, the five-sided plug can limit the rotating disk, and then put the high-locking nut to be punched into the nut groove above the through groove, and then start the hydraulic cylinder. The output end of the hydraulic cylinder drives the rectangular block to move downward, and the rectangular block will drive the rotating disk and several punching heads to move downward. The punching head located above the through groove moves downward to punch the high-locking nut, and the residue dropped by the punching will enter the collection box through the through groove, which is convenient for personnel to collect it, ensuring that the overall device can punch high-locking nuts of different sizes, thereby increasing the practicality of the overall device.

[0021] In the above technical solution, further, one end of the five-sided plug block is plugged into the five-sided groove one, and the cross-sectional dimensions of the five-sided groove one, the five-sided groove two and the five-sided plug block are equal.
