Description

Technical Field

[0001] The utility model relates to the technical field of anti - jamming devices, and specifically relates to an anti - jamming device for lifting a jig platform of a circuit board splitting machine. Background Art

[0002] A jig is a large - category tool for carpentry, ironworking, fitter work, machinery, electronic control, and some other handicrafts. It is mainly a tool used to assist in controlling positions or movements. In a circuit board splitting machine jig, the jig platform needs to perform ascending and descending operations. Therefore, telescopic rod bodies such as electric telescopic rods or pneumatic cylinders and hydraulic cylinders are used for lifting work.

[0003] For the existing jig platform of a circuit board splitting machine, when performing the lifting operation, it directly uses a telescopic rod to complete. The telescopic rod is only a single combined rod body of electric, pneumatic, or hydraulic. During the lifting operation, it is difficult to ensure the stability of the movable rod body in the telescopic rod, which may lead to deviation and jamming, or even deviation and jamming to death, thus affecting the lifting operation of the entire jig platform.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and an anti - jamming device for lifting a jig platform of a circuit board splitting machine is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti - jamming device for lifting a jig platform of a circuit board splitting machine to solve the problems raised in the above - mentioned background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An anti - jamming device for lifting a jig platform of a circuit board splitting machine, including an outer cylinder. A lifting rod is arranged inside the outer cylinder. A fixed sleeve is fixedly installed above the outer surface of the outer cylinder. A covering ring is fixedly installed on the outer side of the lifting rod by sleeving on the surface of the fixed sleeve. Connecting frames are fixedly arranged on the front and rear sides of the outer surface of the covering ring. A converging groove is opened on the inner surface of the covering ring. Through - cavities are penetrated through the front and rear sides of the inner surface of the converging groove. A positioning mechanism is arranged inside the covering ring and the connecting frames.

[0007] Preferably, the positioning mechanism includes a bidirectional lead screw rotatably arranged inside the rear connecting frame and a guiding rod fixedly installed inside the front connecting frame. Connecting plates are sleeved on the left and right sides of the surfaces of the bidirectional lead screw and the guiding rod. The connecting plates are slidably connected with the guiding rod and threadedly connected with the bidirectional lead screw.

[0008] Preferably, the positioning mechanism further includes arc - shaped blocks fixedly installed inside the converging groove through the through - cavities at the opposite ends of the front and rear same - side connecting plates. Ball bearings are rotatably arranged on the surface of the arc - shaped blocks close to the center of the covering ring. A soft rubber pad is installed on the inner surface of the arc - shaped blocks.

[0009] Preferably, a locking mechanism is provided on the right side of the outer surface of the connecting frame at the rear side of the covering ring. The locking mechanism is composed of a jack, a movable rod, a handwheel, a ring plate and a spring.

[0010] Preferably, jacks are circumferentially and uniformly distributed on the right side of the outer surface of the connecting frame at the rear side of the covering ring, and a movable rod is inserted into the interior of each jack.

[0011] Preferably, the right end of the bidirectional lead screw penetrates through the connecting frame and is fixedly provided with a handwheel, and the right end of the movable rod slidably penetrates through the handwheel, and the jacks are arranged around the penetrating part of the bidirectional lead screw.

[0012] Preferably, a ring plate is fixedly installed on the left side of the surface of the movable rod, a spring is fixedly installed on the right side of the ring plate, and the right end of the spring is fixedly connected to the handwheel.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the arrangement of the positioning mechanism, the bidirectional lead screw, the guiding rod, the connecting plate, the arc-shaped block, the rolling ball and the soft rubber pad, by rotating the bidirectional lead screw and under the limitation of the guiding rod, the connecting plate drives the arc-shaped block to move synchronously towards the center to wrap the lifting rod. The rolling ball contacts the surface of the lifting rod first, which can fix the lifting axis of the lifting rod, prevent the lifting rod from generating a cylinder disorder phenomenon during movement, and also prevent the occurrence of lifting deviation and jamming. At the same time, it also avoids the contact friction between the lifting rod and the inner wall of the outer cylinder. Due to the self-rotation of the rolling ball, the friction force of the movement of the lifting rod is reduced, the wear of the lifting equipment is avoided, and the service life is prolonged;

[0015] 2. Through the arrangement of the locking mechanism, the jack, the movable rod, the handwheel, the ring plate and the spring, the handwheel can be used to more conveniently rotate the bidirectional lead screw. After the positioning mechanism is adjusted, the spring uses the ring plate to push the movable rod into the jack at the nearest corresponding point, thereby fixing the position of the handwheel and preventing the secondary rotation of the bidirectional lead screw caused by external force or the vibration of the lifting equipment during operation. Furthermore, the stability of the positioning mechanism is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[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] As Figures 1 - 3 shown, a lifting anti-jamming device for a jig platform of a board splitting machine includes an outer cylinder 1. A lifting rod 2 is arranged inside the outer cylinder 1. A fixed sleeve 3 is fixedly installed above the outer surface of the outer cylinder 1. A coating ring 4 is sleeved on the surface of the fixed sleeve 3 and fixedly installed on the outside of the lifting rod 2. Connecting frames 5 are fixedly arranged on the front and rear sides of the outer surface of the coating ring 4. A converging groove 6 is opened on the inner surface of the coating ring 4. Through cavities 7 are penetrated through the front and rear sides of the inner surface of the converging groove 6. A positioning mechanism 8 is arranged inside the coating ring 4 and the connecting frames 5.

[0023] By adopting the above technical solutions, the outer cylinder 1 and the lifting rod 2 form a telescopic lifting device; the fixed sleeve 3 can install the entire anti-jamming structure on the lifting device.

[0024] Furthermore, the positioning mechanism 8 includes a bidirectional lead screw 801 rotatably arranged inside the rear connecting frame 5 and a guide rod 802 fixedly installed inside the front connecting frame 5. Connecting plates 803 are sleeved on the left and right sides of the surfaces of the bidirectional lead screw 801 and the guide rod 802. The connecting plates 803 are slidably connected to the guide rod 802 and threadedly connected to the bidirectional lead screw 801.

[0025] Furthermore, the positioning mechanism 8 further includes arc-shaped blocks 804 fixedly installed inside the converging groove 6 through the through cavities 7 at the opposite ends of the front and rear same-side connecting plates 803. Balls 805 are rotatably arranged on the surface of the arc-shaped blocks 804 close to the center of the coating ring 4. Soft rubber pads 806 are installed on the inner surfaces of the arc-shaped blocks 804.

[0026] By adopting the above technical solution, the connecting plates 803 on the front and rear same sides can form an integral body with the arc-shaped blocks 804. When the bidirectional lead screw 801 rotates, the front end is limited by the guide rod 802, preventing the connecting plate 803 from rotating synchronously with the bidirectional lead screw 801. Furthermore, the connecting plate 803 drives the arc-shaped block 804 to move and gather towards the middle, wrapping and limiting the lifting rod 2 to prevent the lifting rod 2 from deviating and jamming during telescopic movement; the ball 805 preferentially contacts the surface of the lifting rod 2 to avoid contact friction between the lifting rod 2 and the inner wall of the outer cylinder 1. The ball 805 rotates by itself, reducing the friction force of the lifting rod 2 during movement and avoiding wear of the lifting equipment; the soft rubber pad 806 can buffer and isolate the slight friction vibration and noise generated between the lifting rod 2 and the ball 805, improving stability.

[0027] As Figures 3 - 4 shown, a locking mechanism 9 is arranged on the right side of the outer surface of the connecting frame 5 at the rear of the covering ring 4. The locking mechanism 9 is composed of a jack 901, a movable rod 902, a handwheel 903, a ring plate 904, and a spring 905.

[0028] Furthermore, a plurality of jacks 901 are evenly distributed in a circular shape on the right side of the outer surface of the connecting frame 5 at the rear of the covering ring 4, and a movable rod 902 is inserted into the inside of the jack 901.

[0029] By adopting the above technical solution, the jack 901 can limit the movable rod 902.

[0030] Furthermore, a handwheel 903 is fixedly installed through the right end of the bidirectional lead screw 801 and the connecting frame 5, and the right end of the movable rod 902 slidably penetrates through the handwheel 903, and the jack 901 is arranged around the penetrating part of the bidirectional lead screw 801.

[0031] By adopting the above technical solution, when the movable rod 902 penetrates through the handwheel 903, the handwheel 903 can be positioned by the limiting force of the jack 901.

[0032] Furthermore, a ring plate 904 is fixedly installed on the left side of the surface of the movable rod 902, a spring 905 is fixedly installed on the right side of the ring plate 904, and the right end of the spring 905 is fixedly connected to the handwheel 903.

[0033] By adopting the above technical solution, the elastic force of the spring 905 is transmitted to the movable rod 902 through the ring plate 904, enabling the movable rod 902 to be inserted into the jack 901 more stably.

[0034] Working principle: When using the lifting anti-jamming device of the circuit board splitting machine fixture platform, first, pull the movable rod 902 out of the jack 901, and then turn the handwheel 903 to rotate the bidirectional lead screw 801. Under the limitation of the guiding rod 802, the connecting plate 803 drives the arc-shaped block 804 to move synchronously towards the center to wrap the lifting rod 2. The ball 805 preferentially contacts the surface of the lifting rod 2, which can fix and limit the lifting axis of the lifting rod 2. When the lifting rod 2 moves up and down in a vertical state, the ball 805 rotates itself to reduce the friction of the lifting rod 2 during movement and avoid wear of the lifting equipment. After the positioning mechanism 8 is adjusted, the spring 905 uses the ring plate 904 to push the movable rod 902 into the jack 901 at the nearest corresponding point, thereby fixing the position of the handwheel 903 to prevent secondary rotation of the bidirectional lead screw 801 caused by external force or vibration during the operation of the lifting equipment, and thus greatly improving the stability of the positioning mechanism 8. This is the working principle of the lifting anti-jamming device of the circuit board splitting machine fixture platform.
