Description

Technical Field

[0001] The invention belongs to the technical field of automobile stamping die production, and in particular relates to a gear-driven electric adjustment balancing block device. Background Art

[0002] Automation and intelligentization have become the mainstream development path in industrial production. In the field of automotive stamping die production, the blank holder of the stamping die is equipped with a height-adjustable balancing weight to maintain the stable position of the die during the stamping process. The use of automatically adjustable balancing weights is gradually replacing manually added spacers.

[0003] Self-adjusting balancing blocks automatically adjust their height by connecting a servo motor to a human-machine interface panel. This eliminates the need for manual balancing pads and offers advantages such as ease of operation, high precision, and high production efficiency. However, existing self-adjusting balancing blocks have drawbacks in their drive mechanisms. Because the drive block and the adjustment block form point-to-point contact during operation, the pressure applied to these points is extremely high and uneven. This can easily damage the drive block during production, reducing its lifespan and impacting production efficiency.

[0041] Specifically, the front housing 9 and the rear housing 10 are machined with symmetrical grooves in the middle, and both are provided with threaded holes, which are connected by threads to form a cylindrical balance weight housing. Specifically, two threaded holes are opened on the upper part of each of the front housing 9 and the rear housing 10.

[0042] The servo motor 6 is mounted on a front housing 9 with threaded holes through bolt connection. The output shaft of the servo motor 6 drives the main driving worm 1 to rotate, and engages with the helical gear in the driven double gear 2 to drive it to rotate.

[0050] Example 1

[0051] A gear-driven electric adjustment balance weight device consists of a main driving worm 1, a driven double gear 2, a driven gear 3, a support bolt 4, a contact block 5-1, a circular positioning plate 5-2, a servo motor 6, a grating distance sensor 7, a pressure detection piece 8, a front shell 9 and a rear shell 10.

[0052] The servo motor 6 is bolted to a rear housing 10 with threaded holes. The output shaft of the servo motor 6 drives the rotation of the driven gears 3, meshing with the helical gears in the driven duplex gears 2. The pinion of the driven duplex gears 2 drives the four driven gears 3 to rotate, achieving synchronous electric adjustment.

[0053] The driven gear 3 is threaded and integrally connected to the support bolt 4. As the driven gear 3 rotates, the support bolt 4 rotates synchronously. The front housing 9 and the rear housing 10 each have two threaded holes on their upper portions, which are threadedly connected to the support bolt 4. As the support bolt 4 rotates, the support bolt 4 and the driven gear 3 move axially together. The circular positioning plate 5-2 has four holes at its bottom, which are in surface contact with the four support bolts 4. The axial movement of the support bolt 4 can drive the circular positioning plate 5-2 to move together, thereby adjusting the height of the balancing block.

[0054] The top of the circular positioning plate 5 is provided with a groove and a threaded through hole for fixing the pressure detection piece 8 and the internal arrangement of the data line.

[0055] The grating distance sensor 7 is installed on the side of the front housing 9 to detect the position of the circular positioning plate 5-2 and realize real-time monitoring of the height of the balance block.

[0056] Symmetrical grooves are machined in the middle of the front shell 9 and the rear shell 10. The front shell 9 and the rear shell 10 are both provided with four threaded holes, which are connected by bolts to form a balancing block shell with a cylindrical appearance. The interior has four centrally symmetrical grooves for installing the driven spur gear 3 and a central axis groove for installing the driven duplex gear 2; the rear shell is provided with a threaded hole for fixing the servo motor and a through hole for placing the servo motor drive shaft and the main body drive worm 1.

[0057] When in use, if the balancing block needs to be raised, the height to be raised is input through the human-machine interaction panel, and the servo motor rotates forward to make the support bolt 4 rise vertically, and the support bolt 4 contacts the surface of the circular positioning plate 5-2, so that the height of the circular positioning plate 5 rises; if the balancing block needs to be lowered, the height to be lowered is input through the human-machine interaction panel, and the servo motor rotates backward to make the circular positioning plate 5 fall, thereby achieving the effect of adjusting the height.

[0058] Due to the design of the present invention, the four driven spur gears 3 cooperate with the support bolts 4 to always maintain surface contact with the circular positioning plate 5-2. While maintaining the advantages of convenient operation, high precision and high production efficiency of the existing technology, the pressure on the servo motor 6 of the drive device in actual production is reduced, the load-bearing capacity of the self-adjusting balancing block is increased, the failure rate of the device is reduced, and the service life of the self-adjusting balancing block equipment is extended.

[0059] The present invention improves the driving device and uses a cylindrical combination driven by internal gears and support bolts as the main part of the driving device, improving the contact mode between the driving device and the adjusting block in the existing self-adjusting balancing block from point contact to surface contact, thereby reducing the pressure on the driving device in actual production, increasing the load-bearing capacity of the self-adjusting balancing block, reducing the failure rate of the device, and extending the service life of the self-adjusting balancing block equipment.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
