[0022] See also Figure 1-5 , the utility model provides a technical solution:

[0023] A clamping device fixing seat for automatically driving and pulling pins of a PCB CNC machine tool comprises a connecting seat 1, an actuator 4 located on the top of the connecting seat 1 is used to rotate a sleeve 2 in the connecting seat 1, and a plurality of chucks 12 complete the clamping process of the pins under the transmission of a shaft body 7, a connecting rod 8 and a crank 9, and then the device is driven to move by a cylinder or a motor to realize the driving and pulling process of the pins, which effectively improves the efficiency of driving and pulling the pins. The actuator 4 is a servo motor.

[0024] like Figure 1-2 As shown, the sleeve 2 is connected to the output shaft of the actuator 4, and the outer circumference of the output shaft of the actuator 4 and the inner circumference of the sleeve 2 are both provided with keyways, and connecting keys are arranged in the keyways. The ends of the multiple shaft bodies 7 in the sleeve 2 are connected to the connecting rod 8, and the number of the shaft bodies 7 is at least two. The shaft body 7 and the connecting rod 8 are rotationally connected, and the end of the connecting rod 8 is rotationally connected to the crank 9. The chuck 12 is arranged at the end of the crank 9 and passes through the guide plate 3. When the sleeve 2 rotates, the connecting rod 8 is displaced, and the crank 9 starts to drive the movable chuck 12 to move synchronously under the guidance of the guide plate 3. The sleeve 2 can be customized according to actual usage. In this embodiment, the number of the shaft bodies 7 is three, and the sleeve 2 has a cylindrical structure.

[0025] Furthermore, in order to enable the guide plate 3 to guide the crank 9 , a plurality of slide grooves 11 are provided on the guide plate 3 , and a slider 10 corresponding to the slide grooves 11 is provided on the crank 9 .

[0026] like Figure 3 As shown, the center axis of the shaft body 7 is at the same distance from the center axis of the sleeve 2, so that the crank 9 can be driven synchronously, ensuring that the displacement distance of the crank 9 is the same as the rotation of the sleeve 2.

[0027] like Figure 4 As shown, the connecting seat 1 includes a substrate 101, a first end seat 102 is arranged on one side of the lower surface of the substrate 101, a second end seat 104 and a third end seat 106 are arranged at the top corners on both sides of the other side of the lower surface of the substrate 101, a first stop 103 is opened at the bottom of the first end seat 102, and a second stop 105 is opened at the bottom of the second end seat 104, and the lengths of the first end seat 102 and the second end seat 104 are both greater than the third end seat 106.

[0028] like Figure 5 As shown, the guide plate 3 includes a plate body 301 , and two adjacent side surfaces of the plate body 301 are provided with a first protrusion 302 and a second protrusion 303 corresponding to the first stop 103 and the second stop 105 .

During installation, the guide plate 3 and the connecting seat 1 are fitted together, and the first protrusion 302 is inserted into the first stop 103, and the second protrusion 303 is inserted into the second stop 105, and then the guide plate 3 is fixed to the threaded holes reserved at the bottom of the first end seat 102, the second end seat 104 and the third end seat 106 by bolts.

[0030] By adopting the above structure, the accuracy and stability of the position during installation can be ensured, and by adopting the first stop 103, the second stop 105, the first protrusion 302 and the second protrusion 303 in coordination, the installed guide plate 3 and the connecting seat 1 can withstand a larger torque, thereby solving the problem of the guide plate 3 and the connecting seat 1 breaking due to insufficient torque transmission strength or excessive torque.

[0031] like Figure 1 As shown, one side of the top of the connection seat 1 is connected to a mounting plate 6 via a connecting member 5 , and the mounting plate 6 is used to fix the actuator 4 , wherein there are two connecting members 5 , and the actuator 4 is arranged between the two connecting members 5 .

[0032] The use principle and use process of the utility model are as follows: when clamping the pin, the sleeve 2 starts to rotate by controlling the actuator 4, and the three chucks 12 move toward the center position of the sleeve 2 under the transmission of the shaft body 7, the connecting rod 8 and the crank 9 until the chucks 12 are tightly fitted with the pin, completing the clamping work of the pin, and then the device is driven to move by the cylinder or the motor to realize the pin pulling process.

[0033] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several deformations, substitutions and improvements can be made without departing from the concept of the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be based on the claims.
