Description

Technical Field

[0001] This utility model belongs to the field of tire nail machine gun head adjustment technology, and particularly relates to a tire nail machine gun head rotation structure. Background Technology

[0002] Studded snow tires are traditional snow tires with added metal studs. These studs penetrate deep into ice and snow, increasing the contact area between the tire and the icy surface, thus greatly improving grip and anti-skid performance. Studded snow tires perform exceptionally well in extremely cold and icy environments, providing drivers with safer and more reliable driving protection.

[0003] During the processing, tire stud machines are usually needed to press metal studs into the tire. In actual operation, the tire stud machine head acts directly on the tire surface. Since the outer surface of the tire is a curved structure, most existing technologies use a structure that is directly perpendicular to the ground, pressing the tire stud machine head into the tire surface. The metal studs that are pressed in vertically have poor grip when dealing with icy roads with complex structures. Currently, the pressing mechanism cannot be rotated properly to make the tire stud machine head and the tire surface present a suitable angle so that the metal stud can conform to the tire surface structure to provide a multi-directional grip effect. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] This utility model embodiment provides a rotating structure for a tire stud gun head, such as... Figures 1-6 As shown, the nail gun head 500 is used in a tire stud machine, and the rotating structure of the nail gun head includes:

[0030] The system comprises a primary support platform 110 and a secondary support platform 120. The primary support platform 110 is equipped with a rotating mechanism 200, which includes a servo motor 210 and a harmonic reducer 220. The primary support platform 110 has an equipment hole for accommodating the harmonic reducer 220. The power output shaft of the harmonic reducer 220 passes through the equipment hole into the primary support platform 110. Both the servo motor 210 and the harmonic reducer 220 are bolted to the side of the primary support platform 110 away from the secondary support platform 120. The secondary support platform 120 is mounted on the power output shaft of the harmonic reducer 220 and rotates relative to the primary support platform 110 under the drive of the rotating mechanism 200.

[0031] The stroke cylinder 310 and the nail pressing cylinder 320 adopt the principle of cylinder push rod technology in the prior art. The detailed structure is not described in detail. The secondary support platform 120 is provided with a fixed seat 410 and a sliding seat 420. The stroke cylinder 310 is connected to the secondary support platform 120 through the fixed seat 410, and the nail pressing cylinder 320 slides on the secondary support platform 120 through the sliding seat 420. The nail pressing cylinder 320 acts on the gun head 500.

[0032] In this embodiment, the primary support platform 110 directly rotates the secondary support platform 120 using the rotating mechanism 200. The primary support platform 110 uses the X-axis and Z-axis adjustment mechanism provided on the tire stud machine in the prior art as a drive to change its distance from the tire. After the initial adjustment is completed, the tire stud machine gun head rotating structure approaches the tire surface. After the X-axis and Z-axis adjustment mechanism completes the initial adjustment, the tire stud machine gun head rotating structure rotates between the secondary support platform 120 and the primary support platform 110 to allow the tire stud machine gun head to present a suitable angle with the tire surface. The stroke cylinder 310 uses its own stroke push rod 311 to push the nail pressing cylinder 320 and the tire stud machine gun head closer to the tire surface. The nail pressing cylinder 320 directly pushes the anti-slip stud in the tire stud machine gun head into the tire with its own pressing push rod 321.

[0033] In this embodiment, the primary support platform 110 directly deflects the secondary support platform 120 through the rotating mechanism 200, so that the moving direction of the stroke cylinder 310 and the nail pressing cylinder 320 can present an appropriate angular relationship with the tire surface. The rotating mechanism 200 gives the tire nail gun head equipment adjustment capability, ensuring that the pressed metal nail has a high grip effect and provides multi-directional grip force.

[0034] The stroke cylinder 310 and the nailing cylinder 320 cooperate with each other and are linked with other components of the tire nailing machine. The nailing cylinder 320 pushes forward before nailing and is promptly withdrawn after nailing to avoid affecting the tire rotation and position adjustment. In this application, the sliding seat 420 includes a loading plate 421, a sliding block 422 and a slide rail 423. The nailing cylinder 320 is connected to the loading plate 421. The number of sliding blocks 422 is two sets, which are disposed at both ends of the loading plate 421. The number of slide rails 423 is also two sets, which are arranged on the secondary support platform 120 parallel to the pushing direction of the stroke cylinder 310. The sliding block 422 slides on the slide rail 423. The double track structure further ensures the stability of the nailing cylinder 320 during the nailing process and improves the efficiency and quality of nailing.

[0035] In a preferred embodiment of this invention, the fixing base 410 includes an upper fixing plate 421 and a lower fixing plate 412, which are L-shaped structures. The upper fixing plate 421 and the lower fixing plate 412 are respectively fixed to both ends of the stroke cylinder 310.

[0036] The lower fixing plate 412 is located on the side of the stroke cylinder 310 near the nail pressing cylinder 320. The lower fixing plate 412 is provided with a first punch hole to accommodate the stroke push rod 311. After passing through the first punch hole, the stroke push rod 311 is connected to the end of the nail pressing cylinder 320 away from the gun head 500.

[0037] In a preferred embodiment of this invention, the loading plate 421 is disposed at the end of the nail pressing cylinder 320 away from the stroke cylinder 310, and the loading plate 421 is provided with a second punch hole to accommodate the passage of the pressing push rod; the loading plate 421 adopts a trapezoidal structure, and end blocks are provided at both ends of the bottom of the loading plate 421, and the loading plate 421 is connected to the sliding block 422 through the end blocks;

[0038] In a further preferred embodiment of this utility model, the servo motor 210 and the harmonic reducer 220 are both existing technical structures. The equipment hole provided on the primary support platform 110 in this application is adapted to the housing of the harmonic reducer 220. The servo motor 210 and the harmonic reducer 220 are both fixed to the side of the primary support platform 110 away from the secondary support platform 120 by bolts. The power output shaft of the harmonic reducer 220 extends to the other side of the primary support platform 110 through the equipment hole. The secondary support platform 120 is fixed to the power output shaft of the harmonic reducer 220.
