[0021] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application will be further described below in combination with specific embodiments.

[0022] As an embodiment of the present application, as shown in Figure 1 , 2The utility model provides a kind of telescopic beat axle rod for can sealing machine, including rod body 1, locking nut 2, bearing assembly 3, spring assembly 4 and snap ring 5 are sequentially equipped with from top to bottom on the upper end of rod body 1.

[0023] Specifically, the rod body 1 is an axial hollow or solid cylindrical structure, and the beat axle head 6 penetrates through the rod body 1, which is used to bear the main body support and power transmission function. The surface of the rod body 1 is provided with a stepped outer diameter change: the upper end is processed as a bearing matching section, which is used for sliding fit with the inner ring of the bearing assembly 3.

[0024] The bearing assembly 3 is sleeved on the upper end of the rod body 1, and the inner ring is slidingly fitted with the rod body 1, and the outer ring is detachably connected with the mounting cavity 62 of the beat axle head 6.

[0025] The snap ring 5 is provided at a certain distance below the bearing assembly 3 and is integrally formed with the rod body 1, and an annular clamping groove is formed between the bearing assembly 3 and the snap ring 5, which is used for sleeving the spring assembly 4. The spring assembly 4 is composed of a spiral compression spring, which is sleeved on the outer side of the rod body 1, and the upper end abuts against the lower end surface of the bearing assembly 3, and the lower end is limited by the snap ring 5. The outer diameter of the snap ring 5 is greater than the inner diameter of the spring assembly 4, forming a rigid stop surface at the bottom of the spring. In order to enhance the stop strength of the snap ring 5, the snap ring 5 is integrally formed with the rod body 1.

[0026] The core role of the spring assembly 4 in the present application is as follows:

[0027] 1) Axial elastic buffering and self-adaptive adjustment:

[0028] Dynamic compensation: the spring assembly 4 applies a pre-tightening force between the bearing assembly 3 and the snap ring 5, and when the external actuator is subjected to axial impact due to sealing pressure or mechanical vibration, the spring absorbs energy through elastic deformation to avoid rigid impact transmission to the inside of the bearing assembly 3.

[0029] Self-adaptive displacement: when the beat axle rod is radially offset due to uneven material filling or container deformation, the spring assembly 4 allows the bearing assembly 3 to slide axially along the rod body 1 by a small amount, maintaining stable contact between the bearing outer ring and the actuator.

[0030] 2) Guarantee of bearing working state:

[0031] Anti-lock design: the spring assembly 4 applies a continuous upward force to keep a small gap between the inner ring of the bearing assembly 3 and the locking nut 2 at all times, even if the rod body 1 is temporarily locked due to foreign matter or thermal expansion, the spring can still push the bearing outer ring to complete the rotation or swing action independently, ensuring continuous sealing process.

[0032] For example, Figure 2 , 3The utility model discloses a kind of retractable punch shaft head 6 for can sealing machine, the punch shaft rod 1 is arranged in the mounting hole 63 of punch shaft head 6 through;Compared with the punch shaft head of prior art, the mounting hole 63 top of the punch shaft head 6 of the present application is equipped with the accommodating cavity 61 of accommodating spring assembly 4, the top of accommodating cavity 61 is equipped with the installation cavity 62 of adapting bearing assembly 3, bearing assembly 3 top is flush with the top of punch shaft head 6;The top of installation cavity 62 is equipped with C type tablet 7, tablet 7 is cooperated with lock nut 2, bearing assembly 3 can be pressed in installation cavity 62;When dismounting, lock nut 2 and C type tablet 7 are disassembled, and rod body 1 can be taken out with bearing assembly 3.
