[0025] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 5As shown, the pressure head with coaxiality correction according to this utility model includes a bushing 13, in which a central inner hole 14 is formed. A connector 2 and a shaft core 6, arranged vertically, are installed within the central inner hole 14. A spring 3, a steel ball 4, and a thrust bearing 5 are installed between the connector 2 and the shaft core 6. The upper and lower surfaces of the thrust bearing 5 abut against the lower surface of the connector 2 and the upper surface of the shaft core 6, respectively. The upper end of the spring 3 abuts against the lower surface of the connector 2, and the lower end of the spring 3 abuts against the steel ball 4. The steel ball 4 abuts against the upper surface of the shaft core 6. The lower surface of the shaft core 6 is provided with a mounting groove 23. A radial bearing 11 is fixed on the opening of the mounting groove 23. A spring 7, a steel ball 8, and a radial shaft 9 are installed in the mounting groove 23. The upper end of the spring 7 abuts against the steel ball 8, the steel ball 8 abuts against the shaft core 6, and the lower end of the spring 7 abuts against the upper end of the radial shaft 9. The upper end of the radial shaft 9 slides within the mounting groove 23. After the lower end of the radial shaft 9 passes through the radial bearing 11, a pressure rod 10 is fixed thereon. The lower end of the pressure rod 10 is formed with a groove for installation with the insert core. The steel ball 4 and the steel ball 8 are coaxially arranged. With this setup, during operation, the pressure head device is assembled on the crimping equipment, with the upper end of connector 2 connected to the drive assembly. During crimping, the insert is installed at the lower end of the pressure rod 10, and the product to be crimped is placed below the insert. When the drive assembly operates, it drives connector 2 to press the entire pressure head device downwards. During the downward pressing process, the pressure rod 10 causes the insert to contact the product to be crimped. The spring 7 acts as a buffer, cushioning the contact until the insert abuts against the upper end of the mandrel 9 and the steel ball 8, preventing the insert from contacting the product to be crimped. When the hard contact between the insert and the product to be crimped is in a different axial position, that is, when the insert is slightly tilted relative to the product to be crimped, the spindle 9 will tilt slightly under the force. Under the action of spring 3, steel ball 4 and thrust bearing 5, the spindle 6 is finely adjusted to correct the concentricity position, thereby adjusting the spindle 9 to be vertical, driving the insert and the product to be crimped to be in a coaxial position. Then, the pressure is continued to press down to make the insert and the product to be crimped together, thereby improving the coaxial crimping installation yield of the insert and the product to be crimped.

[0027] Of course, when the insert and the product to be crimped are aligned, that is, when they are in a coaxial position, when the drive connector 2 drives the pressing head device to press down as a whole, the insert will not tilt slightly under the force of the spindle 9, and can be directly crimped onto the product to be crimped without the need for position correction.

[0028] Preferably, the pressure bar 10 is a ceramic pressure bar or an iron pressure bar.

[0029] Furthermore, the upper surface of the shaft core 6 is formed with a groove 21 corresponding to and limiting the position of the first steel ball 4, and the inner wall of the mounting groove 23 is formed with a groove 22 corresponding to and limiting the position of the second steel ball 8. This arrangement, through the grooves 21 and 22, limits the position of the first steel ball 4 and the second steel ball 8, preventing the first steel ball 4 and the second steel ball 8 from rolling relative to the shaft core 6.

[0030] Furthermore, the upper surface of the shaft core 6 is provided with a second mounting groove 20 for mounting the thrust bearing 5. This arrangement limits the position of the thrust bearing 5 through the second mounting groove 20. In practical applications, the lower end of the thrust bearing 5 is located within the second mounting groove 20, and the upper end extends out of the second mounting groove 20 to abut against the connector 2.

[0031] Furthermore, the lower surface of the connector 2 is provided with a mounting groove 18 that mates with the spring 3. This arrangement allows the mounting groove 18 to limit the position of the spring 3.

[0032] Furthermore, the lower end of the connector 2 is confined within the central inner hole 14 by a retaining ring 1, and the upper end of the connector 2 extends out of the central inner hole 14 and connects to the drive assembly. A retaining groove 15 is formed on the inner wall of the central inner hole 14 to mate with the retaining ring 1, and an upper limit step 17 is formed on the outer wall of the connector 2 to limit its movement in conjunction with the retaining ring 1. This configuration allows the lower end of the connector 2 to be easily secured within the central inner hole 14 by the retaining ring 1.

[0033] Furthermore, a limiting step 16 is formed on the inner wall of the central inner hole 14, and a lower limiting step 19 is formed on the outer wall of the shaft core 6 to cooperate with and limit the limiting step 16. This arrangement allows the limiting step 16 to limit the shaft core 6, preventing it from coming out of the lower end of the central inner hole 14, and allowing the shaft core 6 to slide slightly upward when subjected to force, thus forming a pressure on the upper and lower surfaces of the thrust bearing 5 in conjunction with the connector 2.

[0034] Furthermore, the radial bearing 11 is positioned on the opening of the mounting groove 23 by a retaining ring 2 12. The inner wall of the mounting groove 23 is formed with a retaining groove 24 that cooperates with the retaining ring 2 12 for positioning and a limiting step 26 that cooperates with the upper surface of the radial bearing 11 for positioning. This arrangement facilitates assembly by securing the radial bearing 11 on the opening of the mounting groove 23 with the retaining ring 2 12.

[0035] Furthermore, a limiting part 25 is formed at the upper end of the radial spindle 9. The upper surface of the limiting part 25 abuts against the lower end of the second spring 7, and the lower surface of the limiting part 25 abuts against the radial bearing 11. This arrangement prevents the radial spindle 9 from coming out of the mounting groove 23 and facilitates its abutment against the second spring 7 and the second steel ball 8.

[0036] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present utility model.
