[0030] Please see Figures 1-5A self-locking open flange type guide shaft support includes: an open flange type guide shaft support body 1, and: a first mounting groove 2 located at the top front side of the left end of the open flange type guide shaft support body 1; a threaded hole 3 located in the middle of the inner bottom wall of the first mounting groove 2 and penetrating downward through the open flange type guide shaft support body 1; a locking screw 4 screwed into the inside of the threaded hole 3; and a self-locking mechanism 5 located at the left end of the open flange type guide shaft support body 1 and positioned for locking. Above the rear side of screw 4; wherein the locking screw 4 is screwed into the threaded hole 3, so that it presses against the opening of the open flange type guide shaft support body 1 for locking and fixing, thereby enabling the guide shaft (not shown) fiber to be inside the open flange type guide shaft support body 1. At the same time, by setting a self-locking mechanism 5 on the rear side of the left end of the open flange type guide shaft support body 1, the self-locking mechanism 5 can always be in contact with the top of the locking screw 4 without the action of external force, so as to prevent the locking screw 4 from loosening or moving due to vibration conditions or other reasons.

[0031] Furthermore, the self-locking mechanism 5 includes a mounting slot 6 located in the middle of the left end of the open flange type guide shaft support body 1, and a through hole 7 located in the middle between the mounting slot 6 and the first mounting groove 2; a self-locking pin 9, which is slidably fitted inside the mounting slot 6, with one end of the self-locking pin 9 away from the mounting slot 6 sliding through the through hole 7 and extending into the interior of the first mounting groove 2 to contact the top of the locking screw 4; and a spring 8, which is fixedly connected between the inner wall of the mounting slot 6 and the self-locking pin 9. The self-locking pin 9 can slide smoothly in the mounting slot 6 and the through hole 7, so that the self-locking pin 9 is always located at the front end of the mounting slot 6 under the action of the spring 8, so that the self-locking pin 9 is always in contact with the top of the locking screw 4 without the action of external force. This prevents the locking screw 4 from loosening or moving due to vibration or other reasons after the open flange type guide shaft support body 1 is locked, thus preventing the guide shaft from being not firmly fixed, improving the stability of equipment operation, the service life of equipment, and the safety of processing and production.

[0032] Furthermore, the cross-section of the self-locking pin 9 is a horizontal T-shape; the vertical end of the self-locking pin 9 slides into the mounting slot 6, and its horizontal end slides through the through hole 7 and extends into the first mounting slot 2 to contact the top of the locking screw 4, thereby improving the stability and reliability of self-locking.

[0033] Furthermore, a frustum 14 is fixedly connected to the middle of one end of the self-locking pin 9 inside the mounting slot 6, and the end of the spring 8 near the self-locking pin 9 is sleeved on the outside of the frustum 14; wherein the frustum 14 can support and limit one end of the spring 8, and at the same time, the rear end of the frustum 14 can contact the rear inner wall of the mounting slot 6, so as to avoid excessive force damaging the spring 8 when the self-locking pin 9 is moved backward by external force.

[0034] Furthermore, the left inner wall of the mounting slot 6 is provided with a stepped groove 10, and the middle of the front inner wall of the stepped groove 10 is provided with an extension hole that connects to the first mounting slot 2; wherein the extension hole is connected to the mounting slot 6, the through hole 7 and the first mounting slot 2 respectively.

[0035] Furthermore, a dust cover 11 is interference-fitted inside the stepped groove 10. A mating plate 12 is integrally formed at the front center of the dust cover 11, and the mating plate 12 is interference-fitted inside the extension hole. Since dust and foreign objects may enter the mounting slot 6, causing the spring 8 and self-locking pin 9 to become contaminated and rusty, and reducing the rebound performance of the self-locking structure, thus affecting the stability and service life of the self-locking structure, the dust cover 11 can be interference-fitted inside the stepped groove 10 to prevent dust and foreign objects from entering the mounting slot 6. The material of the dust cover 11 includes, but is not limited to, plastic.

[0036] Furthermore, the end of the mating plate 12 away from the dust cover 11 is provided with an arc surface that matches the circumferential surface of the left end of the open flange type guide shaft support body 1. A clamping block 13 is fixedly connected to the right side of the mating plate 12 and the end near the dust cover 11. The end of the clamping block 13 away from the mating plate 12 is in contact with the self-locking pin 9. The mating plate 12, the clamping block 13 and the dust cover 11 work together to cover the mounting slot 6 and the through hole 7. At the same time, the clamping block 13 and the self-locking pin 9 are in sliding engagement, thereby limiting and guiding the self-locking pin 9.

[0037] Furthermore, a bushing 19 is installed inside the shaft hole of the open flange type guide shaft support body 1. The bushing 19 is made of rubber and has a C-shaped cross-section. The bushing 19 ensures that the open flange type guide shaft support body 1 fits more snugly when locking the guide shaft and there is no direct contact between metal parts, which reduces friction between metal parts, improves locking stability and the service life of the guide shaft, and improves equipment stability.

[0038] Furthermore, a second mounting groove 15 is provided on the rear side of the left end of the open flange type guide shaft support body 1, corresponding to the position of the first mounting groove 2. A through hole 16 communicating with the mounting groove hole 6 is provided in the middle of the front inner wall of the second mounting groove 15. An opening and closing mechanism is provided inside the second mounting groove 15. The opening and closing mechanism can always be located at the front end of the second mounting groove 15 without the action of external force, ensuring the stability of the self-locking mechanism 5. At the same time, when operating the locking screw 4, the self-locking pin 9 can be easily moved out of the top of the locking screw 4 through the opening and closing mechanism.

[0039] Furthermore, the opening and closing mechanism includes a pull seat 18, with a pull rod 17 fixedly connected to the middle of the front side of the pull seat 18. The end of the pull rod 17 away from the pull seat 18 slides through the through hole 16 and extends into the interior of the spring 8. The extended end of the pull rod 17 is fixedly connected to the frustum 14. The front side of the pull seat 18 contacts the inner wall of the front side of the second mounting groove 15. Under the action of no external force and the action of the spring 8, the pull seat 18 is always in contact with the inner wall of the front end of the second mounting groove 15. When the locking screw 4 is operated, the pull seat 18 can be pulled backward, causing the pull seat 18 to drive the pull rod 17 to slide in the through hole 16. The pull rod 17 can drive the self-locking pin 9 to move into the mounting groove 6 through the frustum 14, thereby moving the horizontal end of the self-locking pin 9 out of the locking screw 4, making the operation convenient.

[0040] Working principle and usage process of this utility model:

[0041] In use, first place the bushing 19 into the shaft hole of the open flange type guide shaft support body 1 and adjust the position of the bushing 19. Then, insert one end of the guide shaft to be installed into the bushing 19 and adjust the position of the guide shaft. Next, by pulling the pull seat 18 backward, the pull seat 18 drives the pull rod 17 to slide in the through hole 16. The pull rod 17 can drive the self-locking pin 9 to move into the mounting slot 6 through the frustum 14. At the same time, the self-locking pin 9 compresses the spring 8, causing the horizontal end of the self-locking pin 9 to retract into the through hole 7. Then, screw the locking screw 4 into the threaded hole 3. During this process, the locking screw 4 presses against the open flange type guide shaft support body 1. The opening is locked in place, and at the same time, the open flange type guide shaft support body 1 presses against the bushing 19, so that the open flange type guide shaft support body 1 fits the guide shaft more closely and there is no direct contact between metal parts, reducing the friction between metal parts; after the locking screw 4 is in place and the guide shaft is fixed, the pull seat 18 is released and under the action of the spring 8, the pull rod 17 is driven to move into the mounting slot 6 and the self-locking pin 9 is driven to move forward in the mounting slot 6. When the pull seat 18 contacts the inner wall of the second mounting slot 15, the horizontal end of the self-locking pin 9 moves to the top of the locking screw 4 and contacts it, completing the self-locking of the locking screw 4.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
