[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] refer to Figure 1-3 A bead stringing machine clamp 2 comprises: a bottom plate 1, on which a through slot 11 is provided; the clamp 2 comprises two clamping plates 21 arranged at a relative interval, and the position between the two clamping plates 21 corresponds to the through slot 11, and the opposite surfaces at both ends of the clamping plates 21 are provided with a first guide hole 22, and a second guide hole 23 coaxially connected with the first guide hole 22 and leading to the other surface, and the diameter of the second guide hole 23 is smaller than the diameter of the first guide hole 22; a guide assembly 3 comprises a guide shaft 31 which is inserted into the second guide hole 23 in the two clamping plates 21, and a limit shaft 32 located in the first guide hole 22 is provided on the guide shaft 31; an elastic member 4 is installed in the first guide hole 22, and the two ends of the elastic member 4 are respectively against the limit shaft 32 and the bottom wall of the first guide hole 22 to perform elastic buffering for clamping the clamping plates 21; a pusher 5 is installed on one side or both sides of the clamp 2 to clamp the two clamping plates 21. It can be understood that the through groove 11 on the bottom plate 1 is used to avoid the steel needle 6. The steel needle 6 is vertically clamped in the two clamping plates 21. The position between the two clamping plates 21, that is, the clamping position of the steel needle 6 corresponds to the through groove 11 up and down. The cooperation between the guide shaft 31 and the second guide hole 23 plays a role in fixing and guiding the two clamping plates 21. Here, both ends of the guide shaft 31 can be fixed on the bottom plate 1 so that the guide shaft 31 is in an axially horizontal state. The limiting shaft 32 can only limit the elastic member 4, or it can cooperate with the second guide hole 23 to play a guiding role. Since the diameter of the first guide hole 22 is larger than the diameter of the second guide hole 23, the end of the first guide hole 22 close to the second guide hole 23 will form a bottom wall, and the two ends of the elastic member 4 are against the bottom wall and the end of the limiting shaft 32 close to the second guide hole 23. If the pusher 5 is installed on one side of the clamp 2, it will push one of the clamps 21 to move toward the other clamp 21 for clamping; if the pusher 5 is installed on both sides of the clamp 2, it will push the two clamps 2 to move toward each other for clamping. When the two clamps 21 are separated, the elastic member 4 is in a compressed state, and there will be elastic resistance to the clamping of the two clamps 21. In this way, when clamping the steel needle 6 or the bead 7, the clamp 21 is pushed to move by the pusher 5, and the clamp 21 is guided and clamped by cooperating with the guide shaft 31. At the same time, the spring will buffer the clamping of the clamp 21 to reduce the impact force on the bead 7 or the steel needle 6.
[0028] Optionally, in some embodiments, reference Figure 1-2The two clamping plates 21 are provided with a plurality of corresponding clamping grooves 24 on the opposite surfaces thereof, and a buffer pad is installed on the clamping groove 24. The clamping groove 24 can be designed according to the size of the steel needle 6 and the size of the bead 7. After the two clamping plates 21 are clamped, the steel needle 6 or the bead 7 is located in the clamping groove 24. The buffer pad can be made of elastic buffer materials such as rubber and silicone. Since the clamping plates 21 are in rigid contact with the steel needle 6 or the bead 7, the addition of a buffer pad can effectively reduce the damage to the steel needle 6 or the bead 7.
[0029] Optionally, in some embodiments, reference Figure 1 and Figure 3 The guide assembly 3 further includes a limiting portion 33 located at both ends of the guide shaft 31 for limiting the clamping plate 21, and the limiting portion 33 is installed on the bottom plate 1. The limiting portion 33 can fix the guide shaft 31 and also limit the separation distance of the two clamping plates 21. When the two clamping plates 21 are against the limiting portion 33, the length of the limiting shaft 32 needs to be kept in the first guide hole 22 without slipping, so as to ensure the stability of the guide.
[0030] Optionally, in some embodiments, reference Figure 3 The elastic member 4 is a spring, and the spring is sleeved on the guide shaft 31. Here, the spring is in the first guide hole 22, and the two ends of the spring are respectively against the bottom wall of the first guide hole 22 and the end of the limit shaft 32. Figure 4 When the two clamping plates 21 are clamped, the spring is compressed in the first guide hole 22. Furthermore, the pusher 5 is a cylinder, and the cylinder is installed on the bottom plate 1 and is provided on both sides of the clamp 2. Since the clamping plate 21 is in the shape of a long strip, the push of multiple cylinders can increase the stability of clamping. Of course, the pusher 5 can also be an electric push rod, and the motor drives the screw rod and the clamping plate 21 to transmit the thread.
[0031] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
