[0001] The utility model belongs to the technical field of actuating cylinders, and particularly relates to an actuating cylinder rod head precision adjustment and locking mechanism. Background Art

[0002] When installing and fixing actuating cylinder products, many challenges are faced. Due to manufacturing precision and the installation direction requirements of rod head bearings (as shown, the rod head is parallel to the oil port), accurately adjusting the length and direction of the screw rod head becomes a crucial task. However, in the prior art, there are often many deficiencies in this adjustment process. Figure 1 Shown, the rod head is parallel to the oil port), accurately adjusting the length and direction of the screw rod head becomes a crucial task. However, in the prior art, there are often many deficiencies in this adjustment process.

[0003] First of all, in the prior art, adjusting the rod head length usually requires disassembling the entire mechanism or performing complex operations, increasing the assembly difficulty and possibly causing error accumulation, affecting the installation accuracy. Secondly, the prior art lacks a high-precision adjustment design, making it difficult to finely adjust the threaded connection installation length during the adjustment process and unable to meet the high-precision installation requirements. In addition, the traditional locking method cannot ensure the stability and reliability of the mechanism, easily leading to loosening or failure, affecting the normal operation of the actuating cylinder and possibly causing equipment damage or safety hazards. For this reason, an actuating cylinder rod head precision adjustment and locking mechanism is proposed. Summary of the Utility Model

[0018] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0020] As Figure 2 shown, a precision adjustment and locking mechanism for an actuator club head provided by an embodiment of the present utility model includes an adjusting sleeve 2, a locking sleeve 3 and a nut 4;

[0021] The main part of the actuator is the piston rod 1. The piston rod 1 is threadedly connected to the adjusting sleeve 2, allowing the adjusting sleeve 2 to move relative to the piston rod 1. The end of the piston rod 1 is connected to a club head 5, and a card slot is provided on the club head 5. Quick adjustment of the precision can be achieved by rotating the club head 5.

[0022] The adjusting sleeve 2 can move along the piston rod 1 through threaded connection to achieve precision adjustment. Card slots are provided on both the piston rod 1 and the adjusting sleeve 2.

[0023] The locking sleeve 3 is arranged at the ends of the piston rod 1 and the adjusting screw sleeve 2 for locking the whole mechanism. A key is arranged inside the locking sleeve 3, and the key is stuck in the slot of the rod head 5 to fix the rod head 5. Teeth are arranged on both sides of the outer circle of the locking sleeve 3. The teeth on one side of the outer circle of the locking sleeve 3 are pressed into the slots of the adjusting screw sleeve 2 and the piston rod 1 to fix and lock the piston rod 1 and the adjusting screw sleeve 2; the teeth on the other side of the outer circle of the locking sleeve 3 are pressed against the nut 4 to achieve multiple locking.

[0024] The nut 4 is used to initially fix the locking sleeve 3 and cooperate with the teeth of the locking sleeve 3 to further increase the reliability of locking.

[0025] In the embodiment of the present utility model, the adjustment method includes quick adjustment and high-precision adjustment, which are specifically as follows:

[0026] Quick adjustment: When the adjustment distance is greater than 1 times the pitch, quick adjustment is performed by rotating the rod head 5;

[0027] High-precision adjustment: When the adjustment distance is less than 1 times the pitch, high-precision adjustment is achieved by adjusting the adjusting screw sleeve 2. Specifically, when adjusting the installation distance between the piston rod 1 and the rod head 5, the in-situ stepped adjustment of the high-precision dimension of "(P outer - P inner) / n" can be achieved by rotating the adjusting screw sleeve 2, where P outer represents the pitch of the external thread of the adjusting screw sleeve, P inner represents the pitch of the internal thread of the adjusting screw sleeve, and n represents the number of slots of the adjusting screw sleeve rotated during adjustment.

[0028] The locking method is as follows:

[0029] After the installation distance between the piston rod 1 and the rod head 5 and the direction of the rod head 5 are adjusted, first tighten with the nut 4 to initially fix the locking sleeve 3. At this time, the key inside the locking sleeve 3 is stuck in the slot of the rod head 5 to fix and lock the rod head 5, ensuring the position stability of the rod head 5 after adjustment. Then, press the teeth on one side of the outer circle of the locking sleeve 3 into the slots of the adjusting screw sleeve 2 and the piston rod 1 to fix and lock the piston rod 1 and the adjusting screw sleeve 2, enhancing the stability and reliability of the whole mechanism. At the same time, press the teeth on the other side of the outer circle of the locking sleeve 3 against the nut 4 to achieve the fixed locking of the locking sleeve 3 and the nut 4, further improving the reliability of locking.

[0030] Quick and high-precision adjustment is performed by rotating the rod head 5 and the adjusting screw sleeve 2, which is simple to operate and reduces the assembly difficulty. During the adjustment process, there is no need to disassemble the whole mechanism, and in-situ adjustment can be achieved only by rotating the rod head 5 and the adjusting screw sleeve 2, improving the work efficiency. Through the high-precision adjustment design, fine adjustment of the installation length of the threaded connection can be achieved, improving the adjustment accuracy.

[0031] Through the multiple locking design (including the locking of the rod head 5, the overall locking, and the fixed locking of the locking sleeve 3 and the nut 4), the stability and reliability of the mechanism are ensured.

[0032] As Figure 2 shown, as a preferred embodiment of the present utility model, a bearing 6 is installed on the rod head 5 to reduce friction and ensure smooth rotation of the rod head.

[0033] The working principle of the present utility model is:

[0034] For the precision adjustment and locking mechanism of the actuator rod head, when the adjustment distance is greater than 1 times the pitch, rapid adjustment is performed by rotating the rod head 5; when the adjustment distance is less than 1 times the pitch, high-precision adjustment is achieved by adjusting the adjusting screw sleeve 2. The locking method is as follows: after the installation distance between the piston rod 1 and the rod head 5 and the direction adjustment of the rod head 5 are completed, first tighten with the nut 4 to preliminarily fix the locking sleeve 3. At this time, the key in the locking sleeve 3 is stuck in the slot of the rod head 5 to fix and lock the rod head 5. Then, the teeth on one side of the outer circle of the locking sleeve 3 are pressed into the slots of the adjusting screw sleeve 2 and the piston rod 1 to fix and lock the piston rod 1 and the adjusting screw sleeve 2. At the same time, the teeth on the other side of the outer circle of the locking sleeve 3 are pressed against the nut 4 to realize the fixed locking of the locking sleeve 3 and the nut 4.

[0035] The above is only the preferred embodiment of the present utility model. It should be pointed out that for those skilled in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
