DETAILED DESCRIPTION
[0022] In order to make the structural features and usage of the present invention clearer, further description will be given below with reference to the accompanying drawings and embodiments.
[0023] like Figures 1 to 3 The universal wire cutting fixture of the present invention includes: a frame 1, a support leg 2, a support plate 3, a slide rail 4, a clamp 5 and a push rod 10. The frame 1 is a rectangular frame, and a support leg 2 is respectively installed at the lower end of the four corners of the above-mentioned frame, and a groove 14 is respectively opened at the upper end of the four corners of the above-mentioned frame 1 with the support leg 2.
[0024] A support plate 3 is fixed to the inner side of one side of the frame 1 by screws 15. A limiting arc groove 16 is opened in the center of one side of the frame 1 connected to the support plate 3. One end of the push rod 10 is mounted on the opposite side of the above-mentioned side. On the other two sides of the frame 1, slide rails 4 are respectively installed by screws 15. The slide rails 4 are dovetail-shaped rails.
[0025] Both sides of the clamp 5 are respectively mounted on the slide rails 4 , and the rear end of the clamp 5 is hinged to the other end of the push rod 10 . The clamp 5 includes: a baffle 6, a spring 7, a spring support plate 8 and a stud 9. The baffle 6 and the spring support plate 8 are placed parallel to each other, and their sides slide on the two slide rails 4. Several studs 9 pass through the spring support plate 8 and are fixed to the baffle 6. A spring 7 is installed on the stud 9 between the baffle 6 and the spring support plate 8. The spring support plate 8 is hinged to the other end of the push rod 10. The baffle 6 is opposite to the support plate 3. The support plate 3 and the baffle 6 opposite to the support plate 3 have the same structure. The upper end surface of the support plate 3 is on the same plane as the upper end surface of the baffle 6 and is parallel to the frame 1. The support plate 3 has a structure with multiple V-grooves 18 and multiple bosses 17 alternating. The clamping piece is placed between the support plate 3 and the baffle 6. Driven by the motor, the push rod 10 pushes the spring support plate 8, spring 7 and baffle 6 to clamp the clamping piece.
[0026] The screw 15 is a countersunk screw.
[0027] The clamp 5 operates as follows: Driven by the motor, the push rod 10 exerts its driving force on the spring support plate 8, forcing the clamp 5 to slide toward the workpiece until the baffle 6 contacts the workpiece. As the push rod 10 continues to extend, further driving force is applied, causing the spring support plate 8 to compress the spring 7. This force is then transmitted to the baffle 6, clamping the workpiece. As the push rod 10 continues to extend, the compression of the spring 7 increases, and the pressure of the baffle 6 on the workpiece also increases. This continuous and gradual increase in clamping force prevents impact on the workpiece and also helps extend the life of the clamp.
[0028] As a preferred technical solution, the push rod 10 can be replaced by other structures or devices that can provide driving force, such as a screw.
[0029] The method of using the utility model is as follows:
[0030] 1) If Figure 4 As shown, when the workpiece is a square plate-like workpiece 11, the workpiece is placed on the plane formed by the top of the support plate 3 and the top of the slide rail 4, and is positioned by installing the side of the boss 17, and the clamp 5 is further driven to clamp the workpiece.
[0031] 2) If Figure 5 As shown, when the workpiece is a circular plate-like workpiece 12, the workpiece is placed on the top of the support plate 3 and is limited by the limiting arc notch 16, and the clamp 5 is further driven to clamp the workpiece.
[0032] 3) If Figure 6 As shown, when the workpiece is a shaft workpiece 13, the workpiece is placed on the V-groove 18 of the support plate 3, and the clamp 5 is further driven to clamp the workpiece.
[0033] 4) If Figure 7 As shown, the universal wire cutting fixture of the present invention can be used in multiple sets in a stacked manner, thereby improving processing efficiency.
[0034] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
