DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0024] Example 1

[0025] like Figure 1-5 As shown, a flip clamping jaw for an automatic screw locking machine comprises a nozzle body 1, a clamping jaw assembly 2 and a flipping mechanism. The nozzle body 1 is arranged on the automatic screw locking machine, and the nozzle body 1 is provided with a first channel 11 for conveying screws and a second channel 12 for a screwdriver rod to pass through;

[0026] The flipping mechanism includes a rotating block 3 and a driving member 4. The nozzle body 1 is hinged to the rotating block 3. The end of the rotating block 3 away from the nozzle body 1 is connected to the clamping jaw assembly 2. A third channel 31 is provided in the rotating block 3. The driving member 4 is used to drive the rotating block 3 to rotate relative to the nozzle body 1 and make the third channel 31 axially connected to the first channel 11 or the second channel 12.

[0027] In the utility model, the structural design of the flipping jaw is ingenious. Through the setting of the flipping mechanism, the jaw assembly 2 can rotate relative to the nozzle body 1, so that the screw and the screwdriver rod can move in a straight line, the movement is smoother and unobstructed, and screws of different lengths can be smoothly entered into the jaw assembly 2 for screw locking, thereby broadening the application scope of the automatic screw locking machine.

[0028] Further, the flip mechanism also includes a movable seat 5, one end of which is connected to the output end of the driving member 4, and the other end of which is hinged to the rotating block 3. Specifically, the driving member 4 is a cylinder, and the piston rod of the cylinder is connected to the movable seat 5. The cylinder drives the piston rod to make linear reciprocating motion. When the piston rod is extended relative to the cylinder body, the movable seat 5 is driven to move downward along the piston cylinder direction, and the movable seat 5 drives the rotating block 3 and the clamping jaw assembly 2 to rotate counterclockwise relative to the clamping nozzle body 1 so that the third channel 31 is axially connected to the first channel 11, so that the screw reaches the clamping jaw assembly 2 through the first channel 11 and the third channel 31; on the contrary, when the piston rod is shortened relative to the cylinder body, the movable seat 5 is driven to move upward, and the movable seat 5 drives the rotating block 3 and the clamping jaw assembly 2 to rotate clockwise relative to the clamping nozzle body 1 so that the third channel 31 is axially connected to the second channel 12, so that the screwdriver rod reaches the clamping jaw assembly 2 through the second channel 12 and the third channel 31 and cooperates with the screw to complete the screw locking.

[0029] Furthermore, a pin hole 32 is provided on one side of the rotating block 3 close to the movable seat 5, and the movable seat 5 is provided with an axial hole corresponding to the pin hole 32. The rotating block 3 passes through the pin hole 32 and the axial hole in sequence through the hinge and is hinged to the movable seat 5. The provision of the pin hole 32 allows the hinge of the rotating block 3 and the movable seat 5 to have a certain degree of freedom.

[0030] Furthermore, the nozzle body 1 is provided with a mounting groove, the driving member 4 is connected to the nozzle body 1 , and the output end of the driving member 4 is passed through the mounting groove and connected to the movable seat 5 .

[0031] Further, an adapter plate 6 is provided on both sides of the nozzle body 1, and one end of the adapter plate 6 is hinged to the rotating block 3. Specifically, one end of the adapter plate 6 is connected to the nozzle body 1, and the other end of the adapter plate 6 is hinged to the rotating block 3, so that the rotating block 3 can rotate relative to the nozzle body 1.

[0032] Furthermore, a locking block 7 is provided on the outer side of the adapter plate 6, and one end of the locking block 7 away from the adapter block protrudes to the outer side of the clamping jaw assembly 2. A gap is left between the locking block 7 and the outer side wall of the clamping jaw assembly 2, and the setting of the locking block 7 can limit the clamping jaw assembly 2 from opening too much.

[0033] Further, the clamping jaw assembly 2 includes a first clamping arm 21 and a second clamping arm 22 that are arranged opposite to each other, and a fourth channel 23 that is axially connected to the third channel 31 is formed between the first clamping arm 21 and the second clamping arm 22. Specifically, the upper ends of the first clamping arm 21 and the second clamping arm 22 are connected to the rotating block 3. The inner side walls of the first clamping arm 21 and the second clamping arm 22 that are opposite to each other are respectively concavely provided with through grooves, and the two through grooves are matched to form the fourth channel 23, and the fourth channel 23 is axially connected to the third channel 31.

[0034] Furthermore, two opposite outer side walls of the rotating block 3 are both provided with slots 33 , and parts of the first clamping arm 21 and the second clamping arm 22 are installed in the corresponding slots 33 .

[0035] Furthermore, the inner side walls opposite to each other of the first clamp arm 21 and the second clamp arm 22 are respectively provided with mounting holes, and an elastic member 8 is provided in the mounting hole, and one end of the elastic member 8 protrudes out of the mounting hole and abuts against the rotating block 3. Specifically, the mounting hole is located at the upper part of the first clamp arm 21 and the second clamp arm 22, and the elastic member 8 is a spring. When the screw reaches the bottom of the fourth channel 23 and continues to move downward, the bottom of the first clamp arm 21 and the second clamp arm 22 is slightly opened, and when the screw passes through the fourth channel 23, the first clamp arm 21 and the second clamp arm 22 can be quickly reset to a closed state under the action of the elastic member 8.

[0036] Furthermore, the bottoms of the first clamp arm 21 and the second clamp arm 22 are symmetrically provided with limiting grooves 24, and the two limiting grooves 24 are matched to form a limiting portion, and the limiting portion is used to limit the movement of the screw in the fourth channel 23. Specifically, the limiting groove 24 is a semi-conical stepped groove formed by the inner side wall of the first clamp arm 21 or the second clamp arm 22, and the two semi-conical stepped grooves are matched to form a conical stepped hole, which serves as a limiting portion for limiting the movement of the screw, so that the screw stays in the conical stepped hole after entering the fourth channel 23.

[0037] The working principle of the flip claw provided by the utility model is as follows: when working, the driving member 4 drives the rotating block 3 to rotate relative to the nozzle body 1 so that the third channel 31 is axially connected with the first channel 11. At this time, the conveying screw enters from the first channel 11 through the third channel 31 to the fourth channel 23, and the limiting part in the fourth channel 23 limits the movement of the screw; then the driving member 4 drives the rotating block 3 to rotate relative to the nozzle body 1 in the opposite direction so that the third channel 31 is axially connected with the second channel 12. At this time, the external screwdriver rod driving structure drives the screwdriver rod to pass through the second channel 12 and the third channel 31 in sequence, and enter the fourth channel 23 to cooperate with the screw. The screwdriver rod continues to push the screw downward along the axial direction of the fourth channel 23 to push open the limiting part, and drives the screw to continue to move downward to cooperate with the preset screw hole to complete the screw locking, and then the screwdriver rod is reset through the fourth channel 23, the third channel 31 and the second channel 12.

[0038] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
