After that, the crystal rod is limited by the clamping tool, and then the stick bonding tool can be used to fit the crystal rod for bonding. After the stick bonding is completed, the stick bonding tool and the crystal rod can be left to stand and firmly bonded, and then the next step can be carried out, and the bonded crystal rod tool is placed in the wire cutting machine for cutting.

However, when replacing the existing metal positioning strips 7, the staff needs to use experience to align the countersunk holes 13 and the positioning holes 14 coaxially. In addition, in the process of holding and replacing the metal positioning strips 7, the staff often operate in an irregular manner, that is, the metal positioning strips 7 are placed from top to bottom on the movable carrier 2 included in the clamping tool, and then the metal positioning strips 7 are moved horizontally to align the countersunk holes 13 with the positioning holes 14, and then the screws are connected for positioning. However, in this process, it is easy for the metal positioning strips 7 to collide with the sensor 8 included in the clamping tool, causing damage to the clamping tool. Utility Model Content

DETAILED DESCRIPTION
[0023] like Figure 1As shown, the clamping fixture in the present invention has the same structure as the clamping fixture in the prior art, including the fixed metal bar 1, the movable carrier plate 2, the fixed stopper 4, the metal positioning bar 7, the sensor 8, the countersunk hole 13 and the positioning hole 14. The countersunk hole 13 is used to cooperate with the screws and the positioning hole 14 to position the metal positioning bar 7 on the movable carrier plate 2, and at the same time achieve the effect of replaceable metal positioning bar 7. After selecting a suitable metal positioning bar 7 and completing the installation and positioning, the crystal rod can be clamped by the relative displacement of the metal positioning bar 7 and the fixed metal bar 1. During this process, the position can be detected by the sensor 8, and then the bonding tool can be used to perform the bonding process of the crystal rod. Different from the clamping fixture in the prior art, Figure 2 As shown, the fixed stopper 4 of the utility model is fixed with a guide bar 5 on one end surface facing the fixed metal bar 1. Figure 3 As shown, the metal positioning strip 7 is provided with a guide groove 6. Figure 1 As shown, the guide strip 5 and the guide groove 6 are slidably matched.
[0024] like Figure 3 As shown, the guide bar 5 and the guide groove 6 are both dovetail-shaped, which can facilitate the staff to dock the guide groove 6 with the guide bar 5, thereby improving the replacement efficiency of the metal positioning bar 7. A lateral limiting block 3 is fixed on the side of the mobile carrier 2 away from the operating station. The lateral limiting block 3 can limit the sliding range of the metal positioning bar 7 on the mobile carrier 2, that is, after the metal positioning bar 7 contacts the lateral limiting block 3, the countersunk hole 13 and the positioning hole 14 are aligned, and then the speed of the countersunk hole 13 and the positioning hole 14 are further improved, that is, the efficiency of the replacement and installation of the metal positioning bar 7 can be improved. At the same time, the metal positioning bar 7 is limited to a single installation method, thereby avoiding the staff's irregular operation, that is, the metal positioning bar 7 is placed on the clamping tool from top to bottom, and then the metal positioning bar 7 is moved horizontally to align the countersunk hole 13 with the positioning hole 14, and then the metal positioning bar 7 is connected with the screw to position the metal positioning bar 7, thereby avoiding the metal positioning bar 7 colliding with the sensor 8 included in the clamping tool to cause damage to the clamping tool.
[0025] When the metal positioning bar 7 included in the clamping tool needs to be replaced, first remove the screws connecting the countersunk hole 13 and the positioning hole 14, and then the metal positioning bar 7 can be pulled to move. During the movement of the metal positioning bar 7, it will be restricted by the sliding connection between the guide groove 6 and the guide bar 5, and then the metal positioning bar 7 of the corresponding model can be matched with the guide bar 5, and then the metal positioning bar 7 can be pushed to slide on the movable carrier 2 under the cooperation restriction of the guide bar 5 and the guide groove 6, and the sliding amount is limited by the lateral limiting block 3, so that the countersunk hole 13 and the positioning hole 14 opened on the replaced metal positioning bar 7 are quickly aligned, and then the metal positioning bar 7 can be connected and positioned to the movable carrier 2 with screws, and then the replacement of the metal positioning bar 7 can be completed.
[0026] like Figure 1 As shown, a guide plate 9 is fixed at the front end of the movable carrier plate 2. The guide plate 9 can assist the staff to place the end of the metal positioning bar 7. Then the staff only needs to push the metal positioning bar 7 to make the guide groove 6 correspond to the guide bar 5. Continuous pushing can make the guide groove 6 slide under the restriction of the guide bar 5, so that the metal positioning bar 7 can be quickly placed in the corresponding position, and the collision between the metal positioning bar 7 and the sensor 8 can be avoided.
[0027] like Figure 1 and Figure 4 As shown, a reinforcing rib 10 is provided between the guide plate 9 and the movable carrier plate 2, and the reinforcing rib 10 can stabilize the relative position of the guide plate 9. An expanded groove 12 is provided at one end of the guide plate 9 close to the operating station, and the expanded groove 12 can facilitate the staff to easily place the metal positioning strip 7 on the guide plate 9 with a high fault tolerance probability. An arc groove 11 is provided on the guide plate 9, and one end of the arc groove 11 is flush with the working surface of the movable carrier plate 2. At the same time, the surface roughness of the guide plate 9 is Ra9.5, thereby maintaining the labor-saving sliding of the metal positioning strip 7 on the guide plate 9 on the arc groove 11.
[0028] The arc groove 11 cooperates with the flared groove 12 to transport the metal positioning bar 7 connected to the guide plate 9 to the guide bar 5, so that the guide groove 6 opened on the corresponding metal positioning bar 7 is connected to the guide bar 5, thereby limiting the metal positioning bar 7 to a single installation method to avoid irregular operation by the staff, that is, avoiding the operation method of placing the metal positioning bar 7 from top to bottom on the movable carrier plate 2 included in the clamping tooling, and then horizontally moving the metal positioning bar 7 to align the countersunk hole 13 with the positioning hole 14, and then connecting the screws to position the metal positioning bar 7, thereby avoiding the metal positioning bar 7 colliding with the sensor 8 included in the clamping tooling to cause damage to the clamping tooling, while also maintaining the effect of quick replacement and installation of the metal positioning bar 7.
[0029] The parts not explained in the above embodiments, such as how the movable carrier 2 drives the metal positioning bar 7 to move and cooperate with the fixed metal bar 1 to clamp the crystal rod to assist the bonding tooling to bond with the crystal rod, why the metal positioning bar 7 needs to be replaced, and why the sensor 8 is arranged on the side of the metal positioning bar 7 away from the clamping position and corresponds to the metal positioning bar 7, should be understood as the prior art known or should be known to those skilled in the art.
