Description

A new type of chuck for billiard cue manufacturing Technical Field

[0001] This utility model relates to the field of billiard cue processing technology, and in particular to a novel chuck for billiard cue processing. Background Technology

[0002] A billiard cue is a tool for striking the ball. It is generally made of wood, tapered at the front and thicker at the back, and no shorter than 91cm. If the cue is too long, it will be difficult to control and will affect aiming and striking the ball. Therefore, it is important to choose a cue that suits your needs. The cue should be round, tapered at the front and thicker at the back, straight, and between 1.3m and 1.5m in length. The diameter of the cue tip (thin end) should be around 9-12mm.

[0003] Announcement No. CN213970776U discloses a novel chuck for billiard cue processing. By setting an adjustment device, the device can fix billiard cues of different specifications, expanding the applicability of the device and making it more convenient in actual use. It eliminates the need for frequent replacement of parts, saving production time. By setting a locking device, the contact area between the locking plate and the billiard cue can be effectively increased, enhancing the fixing effect of the locking device and preventing loosening during processing.

[0004] However, the aforementioned patents still have shortcomings. In actual use, only one end of the billiard cue can be fixed, while the other end is suspended in the air. This makes it prone to shaking, swaying, or vibration under the action of processing force, which affects the quality and performance of the billiard cue. To address this issue, we propose a new type of chuck for billiard cue processing. Summary of the Invention

[0005] The purpose of this invention is to provide a novel chuck for billiard cue processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel chuck for billiard cue processing includes a base, on the upper surface of which symmetrical support plates are slidably connected. Symmetrical bidirectional electric push rods are fixedly mounted on the upper surface of the base. The left and right ends of the two bidirectional electric push rods are connected to the adjacent sides of the two support plates. A rotary motor is fixedly mounted on the upper surface of one of the support plates. Fixing plates are fixedly connected to the upper surfaces of both support plates. First bearings are embedded inside the interior of each of the two fixing plates. A housing is fixedly connected to the inner ring of each of the two first bearings. The output end of the rotary motor is connected to the left side of one of the housings via the first bearings. Symmetrical second bearings are embedded in the inner walls of both housings. Threaded rods are fixedly connected to the inner rings of both sets of second bearings. Symmetrical clamping plates are threaded onto the outer surfaces of both threaded rods. A billiard cue is commonly housed inside the two sets of clamping plates. The top ends of both threaded rods penetrate the second bearings and extend to the upper part of the housing. A handle is fixedly connected to the top ends of both threaded rods.

[0008] In a further embodiment, the upper surface of the base is provided with an opening, and symmetrical mounting seats are slidably connected inside the opening. The upper surfaces of the two mounting seats are connected to the bottom surface of the support plate, and symmetrical third bearings are embedded in the inner walls of the two mounting seats. Rollers are connected to the inner rings of the two sets of third bearings.

[0009] In a further embodiment, symmetrical sliding plates are fixedly connected to the outer surfaces of both mounting bases, and the upper surfaces of both sliding plates are in contact with the inner top wall of the base.

[0010] In a further embodiment, protective pads are fixedly connected to the sides of the two sets of clamps that are close to each other, and the sides of the two sets of protective pads that are close to each other are in contact with the outer surface of the billiard cue.

[0011] In a further embodiment, a limiting plate is fixedly connected inside both of the outer shells, and a buffer pad is fixedly connected to one side of each of the two limiting plates that are close to each other. The side of each of the two buffer pads that are close to each other is in contact with the left and right ends of the billiard cue respectively.

[0012] In a further embodiment, both sets of clamps are slidably connected to limit rods inside, and the upper and lower ends of the two limit rods are connected to the inner wall of the outer shell.

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

[0014] This device rotates the handle, causing the threaded rod to rotate and the two clamping plates to move relative to each other, thus clamping the cue according to the diameter of both ends. A bidirectional electric push rod drives the bearing plate to move relative to each other, thus clamping the cue according to its length. This allows for the fixation of both ends of the cue, solving the problem in the aforementioned patent that could only fix one end of the cue, affecting the quality and performance of the cue manufacturing process.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4. This utility model discloses a novel chuck for billiard cue processing, comprising a base 1. A symmetrical support plate 7 is slidably connected to the upper surface of the base 1. A symmetrical bidirectional electric push rod 9 is fixedly mounted on the upper surface of the base 1. The left and right ends of the two bidirectional electric push rods 9 are connected to the adjacent sides of the two support plates 7. A rotary motor 2 is fixedly mounted on the upper surface of one of the support plates 7. Fixing plates 5 are fixedly connected to the upper surfaces of both support plates 7. First bearings 6 are embedded inside the two fixing plates 5. A housing 3 is fixedly connected to the inner ring of each of the two first bearings 6. The output end of the rotary motor 2 is connected to the left side of one of the housings 3 via the first bearings 6. The inner walls of both housings 3 are embedded with… The two sets of second bearings 19 are symmetrically connected, and the inner rings of the two sets of second bearings 19 are fixedly connected with threaded rods 12. The outer surfaces of the two threaded rods 12 are threadedly connected with symmetrical clamping plates 13. The cue stick 4 is provided inside the two sets of clamping plates 13. The top ends of the two threaded rods 12 pass through the second bearings 19 and extend to the upper part of the outer shell 3. The top ends of the two threaded rods 12 are fixedly connected with handles 18. The handles 18 drive the threaded rods 12 to rotate, so that the two clamping plates 13 move closer to each other and clamp according to the diameter of the cue stick 4. The two bearing plates 7 are moved relative to each other by the bidirectional electric push rod 9, which can clamp both ends of the cue stick 4. The cue stick 4 can be rotated by the rotary motor 2 to facilitate processing.

[0024] The upper surface of the base 1 has an opening 8, and symmetrical mounting seats 11 are slidably connected inside the opening 8. The upper surfaces of the two mounting seats 11 are connected to the bottom surface of the support plate 7. The inner walls of the two mounting seats 11 are inlaid with symmetrical third bearings 20. The inner rings of the two sets of third bearings 20 are connected to rollers 21. Through the cooperation of the mounting seats 11, the third bearings 20 and the rollers 21, the support plate 7 can move smoothly, ensuring the stability of the device operation.

[0025] Two mounting bases 11 are fixedly connected to symmetrical sliding plates 10 on their outer surfaces. The upper surfaces of the two sliding plates 10 are in contact with the inner top wall of the base 1. Through the cooperation of the mounting bases 11 and the sliding plates 10, the mounting bases 11 can be limited to prevent them from shifting under force.

[0026] Protective pads 17 are fixedly connected to the sides of the two sets of clamps 13 that are close to each other. The sides of the two sets of protective pads 17 that are close to each other are in contact with the outer surface of the billiard cue 4. The protective pads 17 are made of rubber, which can prevent the clamps 13 from damaging the surface of the billiard cue 4.

[0027] Both outer shells 3 are fixedly connected to a limiting plate 14 inside. Both limiting plates 14 are fixedly connected to a buffer pad 15 on their adjacent sides. The adjacent sides of the two buffer pads 15 are in contact with the left and right ends of the billiard cue 4 respectively. Through the cooperation of the limiting plate 14 and the buffer pad 15, the billiard cue 4 inserted into the outer shell 3 can be prevented from touching the threaded rod 12, thus limiting the billiard cue 4.

[0028] Both sets of clamping plates 13 are slidably connected to limit rods 16 inside. The upper and lower ends of the two limit rods 16 are connected to the inner wall of the outer shell 3. By sliding the clamping plates 13 on the limit rods 16, the clamping plates 13 can be limited to prevent them from shifting.

[0029] The working principle of this utility model is as follows:

[0030] During use, first insert one end of the billiard cue 4 into the left outer casing 3. Then, rotate the handle 18, which drives the threaded rod 12 to rotate. The threaded rod 12 drives the two clamping plates 13 to move closer together, so that the clamping plates 13 hold one end of the billiard cue 4. Then, the bidirectional electric push rod 9 drives the two bearing plates 7 to move closer together, so that the other end of the billiard cue 4 is inserted into the right outer casing 3. After that, repeat the above operation to hold the other end of the billiard cue 4. Finally, start the rotary motor 2. Since the two outer casings 3 are connected through the billiard cue 4, the billiard cue 4 will rotate so that it can be processed.

[0031] 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 illustrative 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.
