[0025] Installation component 2 includes mounting bracket 21, the top of mounting bracket 21 is fixedly connected with limiting column 22 through support seat 23, and the inner wall of support seat 23 is fixedly connected with the outer wall of limiting column 22, the outside of limiting column 22 is provided with locking cap 24, and the bottom of locking cap 24 is threadedly connected with the threaded column on the top of oil cylinder body 1, the bottom of locking cap 24 is fixedly connected with the top of mounting bracket 21, when installing, the long slot on mounting bracket 21 is aligned with the bolt on the top of oil cylinder body 1, locking cap 24 is tightly threadedly connected with the bolt by rotating, the connection mode utilizes the self-locking characteristic of thread, to ensure that mounting bracket 21 and oil cylinder body 1 are connected firmly, the bottom of mounting bracket 21 is fixedly connected with the top of oil cylinder body 1, the outer wall of limiting column 22 is slidably connected with the inner wall of limiting sleeve 36, and the bottom of support seat 23 is fixedly connected with the top of mounting bracket 21.

[0026] The basis of the locking oil cylinder structure is oil cylinder body 1, installation component 2 is installed on the top of oil cylinder body 1, is responsible for connecting oil cylinder body 1 with limiting component 3, limiting component 3 is slidably connected on the outer wall of installation component 2, is mainly used for limiting the position of telescopic rod of oil cylinder body 1, prevents its displacement in the working process, to further influence the work of machine tool functional components.

[0027] The mounting assembly 2 is mainly composed of a mounting frame 21, a limiting column 22, a supporting seat 23 and a locking cap 24, and its working principle is based on mechanical connection and positioning principle. The bottom of the mounting frame 21 is designed with a long slot matched with the bolts on the top of the oil cylinder body 1. During installation, the long slot on the mounting frame 21 is aligned with the bolts on the top of the oil cylinder body 1, and the locking cap 24 is rotated to be tightly screwed with the bolts. This connection mode utilizes the self-locking characteristics of the thread to ensure the firm connection between the mounting frame 21 and the oil cylinder body 1.

[0028] The inner wall of the supporting seat 23 and the outer wall of the limiting column 22 are fixedly connected by interference fit or welding, which ensures the stability of the limiting column 22. The bottom of the supporting seat 23 is fixedly connected to the top of the mounting frame 21 to provide stable support for the limiting column 22. The limiting column 22 is vertically installed on the mounting frame 21, which provides precise guidance for the sliding of the limiting assembly 3.

[0029] The bottom of the locking cap 24 is designed with an internal thread matched with the threaded column on the top of the oil cylinder body 1. During installation, the locking cap 24 is screwed on the threaded column on the top of the oil cylinder body 1. With the rotation of the locking cap 24, the bottom gradually presses the top of the mounting frame 21. According to the mechanical fastening principle, the mounting frame 21 is tightly fixed on the oil cylinder body 1 under the axial force of the thread by tightening the locking cap 24, which enhances the stability and reliability of the entire connection structure. At the same time, when disassembly or maintenance is needed, the locking cap 24 can be easily released from the fastening state by reversing the rotation.

[0030] The limiting assembly 3 is composed of a limiting shell 31, a soft pad 32, an anti-skid net 34, an anti-skid pad 33, an adjusting screw 35, a limiting sleeve 36, a connecting frame 37 and a fixing frame 38, which involves mechanical adjustment, tribology and mechanical balance principle. Two groups of limiting shells 31 are oppositely arranged. One group of limiting shells 31 is threadedly connected with the adjusting screw 35 through the connecting frame 37, and the other group of limiting shells 31 is rotationally connected with the adjusting screw 35 through the fixing frame 38. When it is needed to adjust the limiting range of the limiting assembly 3, the adjusting screw 35 is rotated. According to the screw transmission principle, the rotation of the adjusting screw 35 is converted into the linear motion of the connecting frame 37. Since the connecting frame 37 is fixedly connected with one group of limiting shells 31, the group of limiting shells 31 is moved along the axial direction of the adjusting screw 35, thereby adjusting the distance between the two groups of limiting shells 31 to adapt to machine tool functional components of different sizes.

[0031] The soft pad 32 of the inner wall of the limiting shell 31 is made of material with certain elasticity and friction coefficient, the anti-skid net 34 of the outer wall of the soft pad 32 and the anti-skid pad 33 of the outer wall of the limiting shell 31 further increase the friction between the telescopic rod of the oil cylinder body 1 and the limiting assembly 3. According to the principle of tribology, rough surface can increase the friction, and the special surface structure of the anti-skid net 34 and the anti-skid pad 33 enables the limiting assembly 3 to compress the telescopic rod on the oil cylinder body 1, preventing displacement during operation.

[0032] The limiting sleeve 36 is fixed to the outer wall of the two groups of limiting shells 31 on both sides, and the inner wall is in sliding connection with the outer wall of the limiting column 22 in the mounting assembly 2. During the sliding process of the limiting assembly 3 along the limiting column 22, the limiting sleeve 36 plays an accurate guiding role, ensuring that the limiting assembly 3 can only move in the axial direction of the limiting column 22, avoiding shaking or deviation. This not only ensures the accuracy of the limiting, but also enhances the stability of the limiting assembly 3 during operation, making the entire locking oil cylinder structure better adapt to the vibration and external interference during the operation of the machine tool.

[0033] First, install the mounting assembly 2 on the oil cylinder body 1, align the long slot at the bottom of the mounting bracket 21 with the bolt at the top of the oil cylinder body 1, rotate the mounting bracket 21 to tightly connect it, then screw the locking cap 24 onto the threaded column at the top of the oil cylinder body 1, and gradually tighten it until the mounting bracket 21 is firmly fixed on the oil cylinder body 1.

[0034] According to the size of the telescopic rod on the oil cylinder body 1, rotate the adjusting screw 35 to adjust the distance between the two groups of limiting shells 31, ensuring that the two groups of limiting shells 31 can clamp the telescopic rod, and the soft pad 32 can fully contact the surface of the telescopic rod.
