[0026] Example

[0027] Reference Figures 1-4 This embodiment provides a Mitsubishi wire cutting machine, including a base 1, an eye mold 2, a water cover 3, and a fixing shell 4 disposed on the base 1. The water cover 3 is fastened to the eye mold 2, and the fixing shell 4 is fastened to the water cover 3. The base 1, eye mold 2, water cover 3, and fixing shell 4 are all prior art and are part of the Mitsubishi wire cutting machine. Grooves 5 are provided on both sides of the fixing shell 4. Two sliders 6 are symmetrically slidably connected to the base 1. More specifically, a connecting block is fixedly connected to the base 1, and the sliders 6 slide on the connecting block. The sliding direction of the sliders 6 is the same as the depth direction of the grooves 5. The machine also includes a mechanism for driving the two sliders 6. A drive mechanism for reversing movement to enter and exit groove 5; the drive mechanism includes a sliding frame 7 slidably connected to the base 1, a guide hole provided on the slider 6, two fixed shafts 8 fixed at both ends of the sliding frame 7, and a locking mechanism. More specifically, the sliding frame 7 is gate-shaped, and two tracks are fixed on the top of the base 1. The sliding frame 7 is slidably connected to the tracks. The fixed shafts 8 pass through the guide hole. The sliding direction of the sliding frame 7 is perpendicular to the sliding direction of the slider 6. The guide hole includes an inclined section 17, and the inclined section 17 forms an angle with the sliding trajectory of the sliding frame 7. The locking mechanism is used to lock the position of the sliding frame 7.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the sliding frame 7 and the fixed shaft 8 slide along the track. Since the sliding direction of the sliding frame 7 is perpendicular to the sliding direction of the slider 6, and the inclined section 17 has an angle with the sliding trajectory of the sliding frame 7, the movement of the fixed shaft 8 causes the slider 6 to slide along the connecting block. When it is necessary to fix the position of the fixed shell 4, as shown... Figure 2 As shown, the sliding frame 7 moves backward, and the slider 6 is inserted into the groove 5 of the fixed shell 4. At the same time, the locking mechanism locks the position of the sliding frame 7 to prevent it from moving. Similarly, when it is necessary to remove the fixed shell 4, simply move the sliding frame 7 in the opposite direction to move the slider 6 out of the groove 5.

[0029] As a preferred embodiment of the present invention, the guide hole further includes a straight section 9, which is connected to one end of the inclined section 17 and is parallel to the sliding trajectory of the sliding frame 7; the guide hole further includes a straight section 10, which is connected to the other end of the inclined section 17 and is parallel to the sliding trajectory of the sliding frame 7.

[0030] In this embodiment, as Figure 2 As shown, straight segment 9 and straight segment 10 are located on both sides of the inclined segment 17. Since straight segment 9 and straight segment 10 are parallel to the sliding trajectory of the sliding frame 7, when the fixed shaft 8 passes through straight segment 9 and straight segment 10, it will not affect the position of the slider 6. Even if the sliding frame 7 shakes slightly, it will not affect the position of the slider 6.

[0031] As a preferred embodiment of this utility model, the base 1 is provided with at least two positioning pins 11 on its top, and the bottom surface of the fixed shell 4 is provided with positioning grooves for the positioning pins 11 to be inserted. In this embodiment, there are two positioning pins 11, which are arranged diagonally opposite each other to ensure that the fixed shell 4 can be accurately positioned during installation.

[0032] As a preferred embodiment of this utility model, the locking mechanism includes a fixed block fixedly connected to the base 1, a positioning ball 12 elastically connected to the fixed block, and two fixing grooves 13 opened on the side of the sliding frame 7 for the positioning ball 12 to extend into. One end of the positioning ball 12 protrudes from the fixed block. When the fixed shaft 8 is on the first straight segment 9 and the second straight segment 10 respectively, one end of the positioning ball 12 is in the two fixing grooves 13 respectively. When it is necessary to move the sliding frame 7, a large force is required to retract the positioning ball 12 into the fixed block, thereby playing a self-locking role.

[0033] As a preferred embodiment of this utility model, such as Figure 4As shown, the fixing block includes a support ring 14 fixedly connected to the base 1, an elastic element 15, and an end cap 16 fixedly connected to the support ring 14. The positioning ball 12 slides inside the support ring 14. The two ends of the elastic element 15 are in contact with the end cap 16 and the positioning ball 12, respectively. The inner wall of the support ring 14 is arc-shaped at the end away from the top cover to prevent the positioning ball 12 from detaching from the support ring 14. The elastic element 15 can be a spring, rubber or elastic polymer material, metal bellows, etc., to provide elasticity so that the positioning ball 12 is always at one end of the support ring 14. With the above arrangement, the positioning ball 12 is elastically installed inside the support ring 14, and when the spring is damaged, the end cap 16 can be opened to replace the spring.

[0034] In a preferred embodiment of this invention, the sliding frame 7 is fixed with an operating part, more specifically, the operating part is a handle, which can be door-shaped or I-shaped, etc. Holding the handle to move the sliding frame 7 not only provides a better grip but also facilitates the operator in applying force, ensuring the smooth movement of the sliding frame 7 and further improving the convenience and safety of operation.

[0035] As a preferred embodiment of this utility model, the outer end of the groove 5 is chamfered, and the slider 6 is chamfered at the end facing the groove 5. The chamfering helps to prevent the slider 6 from getting stuck when it enters the groove 5.

[0036] As a preferred embodiment of this utility model, the fixed shaft 8 is fixed with a bearing, and the outer ring of the bearing contacts the inner wall of the guide hole. By installing the bearing on the fixed shaft 8, the fixed shaft 8 slides more smoothly in the guide hole, reducing friction and improving the smoothness and reliability of sliding.

[0037] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
