[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Please also read Figures 1 to 6 Now, a tooling fixture for preventing misoperation of a screw locking device provided in an embodiment of the present application is described. The tooling fixture for preventing misoperation of a screw locking device comprises: a screw machine 10 and a tooling fixture 20 .

[0033] The jig 20 is used to clamp the product so that the screw machine 10 can perform screwing operations on the product on the jig 20; the screw machine 10 is equipped with a control unit 16 and a control button 17, the jig 20 includes a base 21 and a clamp 22 rotatably mounted on the base 21, the base 21 is equipped with a first induction switch 23, and the first induction switch 23 is connected in series to the circuit of the control button 17 and the control unit 16; the clamp 22 swings down relative to the base 21 to trigger the first induction switch 23 so that the control button 17 and the control unit 16 are connected by signal.

[0034] Specifically, by installing the first induction switch 23 on the base 21 and connecting the first induction switch 23 in series to the circuit of the control button 17 and the control unit 16; only after the clamping plate 22 is fully lowered into place, the first induction switch 23 is triggered to connect the circuit of the control button 17 with the control unit 16. At this time, pressing the control button 17 can transmit the signal to the control unit 16 to control the screw machine 10 to perform the screw driving operation; it can ensure that the tooling fixture 20 can only be used for screw driving when it is fully clamped in place, and the tooling fixture 20 and the product will not be damaged, thereby improving the operation reliability.

[0035] Please also read Figures 3 to 5 In some embodiments of the present application, a first recess 211 is provided on the upper surface of the base 21. The first recess 211 is used to load the product and can maintain the specific position of the product in the front-back and left-right directions. The clamp 22 swings downward relative to the base 21 and clamps the product with the base 21; the clamp 22 is provided with a plurality of avoidance holes running through its upper and lower surfaces, each avoidance hole corresponding to a position of the product where screws need to be driven, and the electric screwdriver 12 of the screw machine 10 can pass through the avoidance hole to enter the position of the product where screws need to be driven to perform screw driving operations.

[0036] Specifically, the first induction switch 23 is installed on the upper surface of the base 21 and is located on the rear side of the base 21. When the clamp 22 swings down relative to the base 21, the lower surface of the clamp 22 can trigger the first induction switch 23; therefore, the first induction switch 23 adopts a mechanical press switch. When the clamp 22 swings down relative to the base 21, the switch can be pressed to connect the circuit between the control button 17 and the control unit 16, so that the operator can start the screw machine 10 to perform the screw driving operation by pressing the control button 17.

[0037] Next, a first pivot shaft 212 is installed on the rear side of the upper surface of the base 21, a first pivot hole 221 for the first pivot shaft 212 to pivot is provided on the rear side of the lower surface of the clamping plate 22, and a first induction switch 23 is provided on the front side of the first pivot shaft 212. A first buckle 222 is rotatably installed on the front side of the clamping plate 22, and a first notch 213 for the first buckle 222 to buckle into is provided on the front side of the base 21; the structure in which the first buckle 222 buckles into the first notch 213 can ensure that the clamping plate 22 will not swing at will during the screwing operation of the tooling fixture 20, thereby further improving the reliability of the operation and preventing the problem of the electric screwdriver 12 crashing into the tooling fixture 20.

[0038] Please also read Figure 3-Figure 6In some other embodiments of the present application, the base 21 is installed with a second induction switch, and the second induction switch 24 is connected in series to the circuit of the control button 17 and the control unit 16; that is, the order in which the control button 17, the control unit 16, the first induction switch 23 and the second induction switch 24 are arranged on the same circuit is the control button 17, the first induction switch 23, the second induction switch 24, and the control unit 16, thereby forming a dual induction mode. Only when the first induction switch 23 and the second induction switch 24 are triggered at the same time can a signal be sent to the control unit 16 by pressing the control button 17, thereby controlling the screw machine 10 to perform the screw driving operation.

[0039] Specifically, a first abutting rod 223 is installed at the front side of the bottom of the clamping plate 22. When the clamping plate 22 is lowered and parallel to the base 21, the first abutting rod 223 triggers the second induction switch 24. The second induction switch 24 is installed at the rear side of the upper surface of the base 21 and is arranged at a vertical spacing from the first induction switch 23. The base 21 is provided with a first through hole 214, and a second abutting rod 215 is movably installed in the first through hole 214. When one end of the first abutting rod 223 abuts against one end of the second abutting rod 215, it can cause the second abutting rod 215 to move backward to trigger the second induction switch 24.

[0040] Preferably, a first inclined surface 2231 is provided at the bottom of the side of the first abutment rod 223, and the first inclined surface 2231 is inclined outward from bottom to top; a second inclined surface 2151 adapted to the first inclined surface 2231 is provided at one end of the second abutment rod 215 facing the first abutment rod 223, and the second inclined surface 2151 is inclined backward from bottom to top; when the splint 22 swings downward relative to the base 21, the first inclined surface 2231 of the first abutment rod 223 can abut against the second inclined surface 2151 and cause the second abutment rod 215 to move backward to trigger the second sensing switch.

[0041] With such a structure, only when the first buckle is buckled into the first notch, the second abutment rod will act on the first abutment rod to trigger the second induction switch; this ensures that the splint will not swing when the screw machine is screwing the product, further improving the reliability of the use of the tooling jig and preventing the screwdriver bit from damaging the tooling jig.

[0042] More specifically, the screw machine 10 includes a base 11, an electric screwdriver 12, a first actuator 13 installed on the base 11 and used to drive the electric screwdriver 12 to move left and right, a second actuator 14 installed on the first actuator 13 and used to drive the electric screwdriver 12 to move up and down, and a third actuator 15 installed on the base 11 and used to drive the tooling fixture 20 to move forward and backward. The third actuator 15 has two arranged with a left and right spacing, and each third actuator 15 is adapted to install a tooling fixture 20 to form a double station. Since the first actuator 13, the second actuator 14 and the third actuator 15 all adopt the common structure in the prior art, such as using a guide rail, installing a slider on the guide rail, installing a movable plate on the slider, and then driving the movable plate to move by a motor and a screw or a motor and a belt, they will not be described one by one here.

[0043] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
