Description

Technical Field

[0001] The utility model relates to the technical field of a structure for clamping a thread end of an elastic thread clamp, in particular to a thread clamp end of a badminton racket wire drawing machine. Background Art

[0002] The badminton racket stringing machine is used to thread the elastic line in the empty racket so that the elastic line is distributed in the racket in a grid shape, thereby producing a complete badminton racket. The core components of the badminton racket stringing machine include a base and a clamping head arranged on the base, wherein the clamping head is installed on the base, and the function of the clamping head is to clamp and fix one end of the elastic line to facilitate the worker to thread the other end of the elastic line into the empty racket.

[0003] The existing thread clamp head includes a hollow rod and a right clamp seat fixed on the top of the hollow rod. A plurality of right clamp teeth are fixed on the top surface of the right clamp seat and arranged at intervals. A cavity is opened on the left end surface of the right clamp seat, and a left clamp seat is slidably installed in the cavity. A plurality of left clamp teeth are fixed on the top surface of the left clamp seat. An adjusting screw is rotatably connected on the left end surface of the right clamp, and a threaded section of the adjusting screw passes through the left clamp seat to the left, and the left clamp seat is threadedly connected to the threaded section.

[0004] When in use, the worker places the elastic wire between the left clamping teeth and the right clamping teeth, and then the worker rotates the threaded head of the adjusting screw, and the threaded head drives the adjusting screw to rotate synchronously. With the cooperation of the left clamping seat and the thread of the adjusting screw, the left clamping seat moves to the right, and the left clamping seat drives each left clamping tooth thereon to move to the right at the same time. After rotating the threaded head a certain number of circles, the left clamping teeth and the right clamping teeth are closed, and the elastic wire is clamped and fixed between the left clamping teeth and the right clamping teeth, which makes it convenient for subsequent workers to insert the other end of the elastic wire into the empty racket.

[0005] However, although this clamping head can be used to fix the elastic line, in actual operation, it still has the following technical defects:

[0006] The worker needs to turn the adjusting screw several times to make the left clamp seat move toward the right clamp seat, and then the left clamp teeth and the right clamp teeth can be closed, so that the elastic line can be clamped and fixed. The worker needs to turn the adjusting screw several times manually, which increases the fixing time of the elastic line and reduces the fixing efficiency of the elastic line. Therefore, there is an urgent need for a clamp head that can clamp and fix the elastic line in a short time and improve the fixing efficiency of the elastic line. Utility Model Content

[0007] The utility model aims to overcome the shortcomings of the prior art and provide a wire clamping head of a badminton racket wire drawing machine which can clamp and fix the elastic wire in a short time and improve the clamping and fixing efficiency of the elastic wire.

[0009] A fixed shaft is fixedly arranged on the left end surface of the right clamp seat and passes through the left clamp seat to the left. A rotating plate is hinged on the fixed shaft via a first pin shaft. A pressure block is detachably connected to the right end surface of the upper end of the rotating plate. The pressure block abuts against the left end surface of the left clamp seat. Under the pressure of the pressure block, the spring I is pressed between the left clamp seat and the right clamp seat.

[0010] The lower end of the rotating plate is hinged with a rotating block via a second pin shaft, and a roller located on the right side of the second pin shaft is rotatably installed on the right end of the rotating block. The roller rests on the left end surface of the right clamp seat, and a shift plate extending downward and tilted to the left is fixedly provided at the bottom of the rotating block; a spring II in a compressed state is pressed between the rotating block and the pressing block, and the left and right ends of the spring II are respectively fixed on the left end surface of the rotating plate and the left clamp seat.

[0011] A blind groove corresponding to the pressing block is formed on the right end surface of the rotating plate, and the left end of the pressing block is interference-fitted with the blind groove.

The pressure block 10 is pressed against the left end face of the left clamp seat 4. Under the pressure of the pressure block 10, the spring I6 is pressed between the left clamp seat 4 and the right clamp seat 2. Two springs I6 are fixedly provided between the left clamp seat 4 and the right clamp seat 2. When the pressure block 10 is worn and damaged, the pressure block 10 can be pulled out from the blind groove 16 of the rotating plate 9 to be replaced with a new pressure block 10, thereby extending the service life of the entire clamp head.

[0028] The lower end of the rotating plate 9 is hinged with a rotating block 12 via a second pin shaft 11, and a roller 13 located on the right side of the second pin shaft 11 is rotatably mounted on the right end of the rotating block 12, and the roller 13 abuts against the left end face of the right clamp seat 2, and a shift plate 14 extending downward and tilted to the left is fixed at the bottom of the rotating block 12; a spring II15 in a compressed state is pressed between the rotating block 12 and the pressing block 10, and the left and right ends of the spring II15 are respectively fixed on the left end faces of the rotating plate 9 and the left clamp seat 4. Among them, the roller 13 and the right clamp seat 2 are in dynamic friction, so the left end face of the right clamp seat 2 will not be damaged, thereby extending the service life of the entire clamp head.

[0029] The right end surface of the rotating plate 9 is provided with a blind groove 16 corresponding to the pressing block 10, and the left end of the pressing block 10 is interference fit with the blind groove 16. The left end surface of the left clamping seat 4 is provided with a waist-shaped hole 17, and the right end of the pressing block 10 is pressed against the bottom of the waist-shaped hole 17.

[0030] The method of the clamping head clamping the elastic line is:

[0031] S1, the hollow rod 1 of the clamping head is mounted on the fixed rod of the base of the badminton racket wire drawing machine;

[0032] S2. The worker first pulls the dial plate 14 upwards in the direction of Figure 2 As shown by the middle arrow, the dial plate 14 drives the rotating block 12 to rotate clockwise around the second pin shaft 11, and the roller 13 on the rotating block 12 moves downward along the left end surface of the right clamping seat 2. When the roller 13 moves downward, the rotating block 12 drives the rotating plate 9 to rotate counterclockwise around the first pin shaft 8, and the rotating plate 9 drives the pressing block 10 to move away from the left clamping seat 4. Under the elastic restoring force of the spring I6, the elastic force of the spring I6 drives the left clamping seat 4 to move away from the right clamping seat 2. At this time, the left clamping tooth 5 on the left clamping seat 4 is separated from the right clamping tooth 3 on the right clamping seat 2.

[0033] S3, when the left clamping tooth 5 is separated from the right clamping tooth 3, the worker places the elastic wire to be fixed between the left clamping tooth 5 and the right clamping tooth 3, at this time, the entire clamping head is in an unlocked state;

[0034] S4. Clamping and fixing of the elastic line. The specific operation steps are as follows:

[0035] S41, the worker presses down the dial plate 14, the dial plate 14 drives the rotating block 12 to rotate counterclockwise around the second pin shaft 11, the roller 13 on the rotating block 12 moves upward along the left end surface of the right clamping seat 2, when the roller 13 moves upward, the rotating block 12 drives the rotating plate 9 to rotate clockwise around the first pin shaft 8, the rotating plate 9 drives the pressing block 10 to move toward the left clamping seat 4, the rotating plate 9 drives the pressing block 10 to move synchronously, the pressing block 10 presses the left clamping seat 4 to the right, the left clamping seat 4 moves toward the right clamping seat 2, and gradually the spring 16, thereby making the left clamping tooth 5 move toward the right clamping tooth 3;

[0036] S42, when the rotating block 12 is reset upward, the elastic line is just clamped and fixed between the left clamping teeth 5 and the right clamping teeth 3, thereby finally achieving the clamping and fixing of the elastic line, thereby facilitating subsequent workers to insert the other end of the elastic line into the empty racket.

[0037] Among them, from the operations of steps S2~S3, it can be seen that the worker only needs to push the dial plate 14 upwards first, and then place the elastic wire between the left clamping tooth 5 and the right clamping tooth 3, and then press the dial plate 14 downwards, so that the elastic wire can be clamped and fixed by the left clamping tooth 5 and the right clamping tooth 3, thereby realizing the rapid clamping and fixing of the elastic wire. Compared with the method of manually rotating the adjustment screw of the transmission, the elastic wire can be clamped and fixed in a short time, thereby greatly improving the clamping and fixing efficiency of the elastic wire.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
