DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1. The purpose of this embodiment is to facilitate the solution that the spindle of the tool clamping cylinder often works under high-speed conditions. Therefore, during the telescopic process of the spindle, swing or vibration may occur, which will affect the overall stability and operating efficiency of the tool clamping cylinder, and may thus lead to increased wear of mechanical components and even possible equipment failure problems. Please refer to Figure 1 - Figure 4 , an electric tool clamping cylinder with a spindle protection device, including a tool clamping cylinder body, a spindle body 200, and a battery box 300 for controlling the tool clamping cylinder body 100. The spindle body 200 is inserted into the tool clamping cylinder body 100, the battery box 300 is installed on the side of the tool clamping cylinder body 100, a piston rod 110 is movably inserted into the tool clamping cylinder body 100, the spindle body 200 is arranged at the bottom of the piston rod 110, a tool head 120 is installed at the bottom end of the spindle body 200, a flange 400 is inserted at the bottom of the tool clamping cylinder body 100, an opening 410 is formed in the flange 400, the spindle body 200 passes through the opening 410 and is connected to the tool head 120, and a stabilizing component 500 is arranged between the flange 400 and the spindle body 200.

[0023] The stabilizing component 500 includes a groove 510 formed in the flange 400. The groove 510 communicates with the opening 410. A damping ring 511 is installed in the groove 510. The groove 510 and the damping ring 511 are provided in two groups, and the two groups of grooves 510 and damping rings 511 are arranged parallel to each other up and down. The damping ring 511 is a rubber ring, and the damping ring 511 is attached to the outer wall of the spindle body 200. The stabilizing component 500 further includes a cavity 520 formed in the flange 400. A telescopic rod 521 is fixedly installed in the cavity 520. A stabilizing rod 522 is fixedly installed at the telescopic end of the telescopic rod 521. A fixing block 523 is fixedly installed at the end of the stabilizing rod 522. A fixing groove 210 corresponding to the fixing block 523 is formed outside the spindle body 200, and the fixing block 523 is engaged with the fixing groove 210. A spring 524 is sleeved outside the telescopic rod 521. One end of the spring 524 is fixedly connected to the inner wall of the cavity 520, and the other end of the spring 524 is fixedly connected to the stabilizing rod 522. A retracting groove 530 corresponding to the fixing block 523 is formed in the flange 400. The retracting groove 530 communicates with the cavity 520, and the fixing block 523 is movably inserted into the retracting groove 530.

[0024] When the spindle drives the tool clamping head 120 to extend, the design of the stabilizing assembly 500 enables the stabilizing rod 522 to move synchronously with the movement of the spindle. The damping ring 511 absorbs the vibrations and oscillations that may occur when the spindle is moving at high speed, maintaining the stability of the spindle operation. The fixing mechanism of the stabilizing rod 522 and the fixing block 523 of the telescopic rod 521 enables the spindle body 200 to be more stable during the extending movement, driving the tool clamping head 120 to work more precisely, and effectively reducing the negative impact of vibrations on the overall operating efficiency of the tool clamping cylinder.

[0025] In this embodiment: Through the damping ring 511 and the stabilizing assembly 500, it is possible to effectively reduce the vibrations and oscillations that may occur when the spindle is rotating at high speed, thereby maintaining the stability and operating accuracy of the spindle. Through the design of the stabilizing rod 522 and the fixing block 523, the stability of the spindle during the extending movement is ensured, enabling the tool clamping head 120 to work more precisely, reducing errors and fluctuations during operation. Reducing vibrations and oscillations can effectively reduce the wear degree of mechanical components, thereby extending the service life of the tool clamping cylinder and its surrounding components, and reducing maintenance and replacement costs.

[0026] Embodiment 2. This embodiment aims to facilitate the solution to the problem that when the spindle body 200 retracts, the stabilizing assembly 500 may remain outside the tool clamping cylinder, resulting in a gap between the stabilizing assembly 500 and the spindle body 200 assembly, and thus the liquid in the tool clamping cylinder flows out. This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 1 - Figure 4 . A baffle 540 is provided at the bottom of the flange 400. A rotating rod 541 is installed at the end of the baffle 540. A rotating groove 542 corresponding to the rotating rod 541 is opened in the flange 400. The rotating rod 541 is rotatably inserted into the rotating groove 542. The rotating groove 542 communicates with the cavity 520. A torsion spring 543 is provided between the cavity 520 and the baffle 540. A plurality of groups of stabilizing rods 522, fixing blocks 523 and baffles 540 are provided. The plurality of stabilizing rods 522, fixing blocks 523 and baffles 540 are arranged in a ring centered on the spindle body 200.

[0027] In this embodiment: The setting of the baffle 540 at the bottom of the flange 400 effectively blocks the liquid that may flow out when the stabilizing assembly 500 retracts. The cooperation between the rotating rod 541 installed at the end of the baffle 540 and the rotating groove 542 in the flange 400 ensures that the stabilizing assembly 500 can block the gap during retraction, thereby effectively preventing the liquid from leaking out from the bottom of the flange 400. The insertion design of the rotating rod 541 and the rotating groove 542 not only ensures the stable movement of the stabilizing assembly 500, but also further prevents liquid leakage by optimizing the sealing performance of the contact surface.
