[0002] When assembling various types of tool pliers such as diagonal pliers, wire cutters and needle-nose pliers, the left and right pliers are generally riveted together by rivets. However, during the riveting process, an axial force is applied to the rivet, causing the rivet to deform and expand radially after being stressed, resulting in the increase in the diameter of the rivet to fix the left and right pliers. Therefore, when workers adjust the opening and closing angles of the pliers handles, they need to apply a very large force to the tool handles to make the adjustment.

[0003] Usually, workers will simply stand the tool pliers on their side so that the outer side of the handle on one side is perpendicular to the workbench, and then use a hammer to hit the handle on the other side to adjust the angle of the handle. However, the impact force of this method, on the one hand, is likely to cause the shape of the pliers handle to change, and on the other hand, it is difficult to accurately control the specific angle of the handle, and the time efficiency of the adjustment is also relatively low.

During the adjustment, the servo motor 2 31 drives the turntable 32 to rotate synchronously to assist in the adjustment.

[0028] Specifically, the base 1 is horizontally arranged, and the transmission device 2 and the positioning device 3 are spaced apart, and the spacing does not exceed the length of the transmission assembly 23 .

[0029] Specifically, the transmission assembly 23 includes: a ball screw 231, which is arranged at the other end of the coupling 22, and the ball screw 231 is used to control the angle adjustment; a screw mounting seat 232, which is arranged at both ends of the ball screw 231, and there are two screw mounting seats 232, one of which is arranged between the coupling 22 and the ball screw 231, and is used to assist the ball screw 231 to be fixedly connected, and the other is arranged at the other end of the ball screw 231 to limit the ball screw 231 and assist the ball screw 231 to rotate; a screw nut 233, which is arranged on the ball screw 231, and the screw nut 233 moves left and right through the rotation of the ball screw 231; a push rod 234, which is arranged on the screw nut 233, and the push rod 234 is used to push the left handle of the tool for adjustment.

[0030] Specifically, when adjusting, the push rod 234 is powered by the servo motor to drive the coupling 22 to transmit, so that the ball screw 231 connected to the other end of the coupling 22 rotates, thereby controlling the push rod 234 fixed on the screw nut 233 to move left and right for angle adjustment. The force point where the push rod 234 contacts the tool is on the same line as the force point on the outside of the right handle of the positioning member 33 fixing the tool.

[0031] Specifically, eight pin holes are provided on the turntable 32. The turntable 32 is in the shape of a disk, with step holes between it, and multiple small pin holes are also provided in the steps. An origin positioning device 353 is provided on the left side of the turntable 32, so that it can be accurately returned to its original position after adjustment. A reducer 34 is also provided on the turntable 32, and the reducer 34 is provided between the turntable 32 and the servo motor 2 31. By reducing the speed and increasing the torque, a stable speed and accurate torque output are provided to ensure that the turntable 32 can rotate stably.

[0032] Specifically, the positioning member 33 is a pin. The positioning member 33 can adjust the position and quantity of the tool according to different types, so that the turntable 32 can place and fix different tools.

[0033] Specifically, a groove is provided at the front end of the push rod 234, and through holes are provided on both sides of the groove. A roller 235 is provided at the front end of the push rod 234, and the roller 235 is fixed to the front end of the push rod 234 through a connecting shaft. The force point where the roller 235 contacts the tool is on the same line as the force point of the positioning piece 33 on the outside of the fixed tool, ensuring that when the push rod 234 pushes the left handle of the tool pliers, the roller 235 rolls with the rotation of the turntable 32, and the sliding friction between the push rod 234 and the tool is changed to rolling friction, so that the push rod 234 will not form scratches on the left handle of the tool pliers, thereby protecting the tool pliers and being able to smoothly and conveniently adjust the angle, thereby achieving the effect of being able to accurately adjust the angle of the tool handle.

[0034] Specifically, Figure 4 As shown, the push rod 234 is pushed from left to right, and the turntable 32 rotates clockwise. Assuming that the force angle between the right handle of the pliers and the upper right positioning pin of the turntable 32 is θ, the combined force on the left and right handles of the side pliers is: F=F1+F2*cosθ.

[0035] Specifically, Figure 4As shown, the ball screw 231 uses a 3205 screw, that is, the screw diameter is 32mm, the lead is 5mm, and its mechanical efficiency is 90%. A 1.5kw servo motor is used, and the torque is about 4.76Nm. Then the thrust of the push rod 234 is F1=4.76 / 5*1000*90%=856N. Adding the rotational thrust of the turntable 32, a 1.5kw servo motor is also selected, and the turntable 32 with a 1:100 reducer 34 has a rotational thrust of F2=4.76*100=470N. Therefore, the resultant force on the pliers handle is F=F1+F2*cosθ=85+470*cosθ.

[0036] Specifically, the present invention is to move the right handle of the tool through the pin shaft turntable 32, and then rotate the servo motor 21, and then drive the screw nut 233 on the ball screw 231 to move to the right through the coupling 22, and synchronously control the push rod 234 connected to the screw nut 233 to move to the right, so that the front roller 235 of the push rod 234 contacts the left handle of the tool, and adjust the angle of the tool handle through the push rod 234, and synchronously rotate the turntable 32, and adjust with the push rod 234, so that the push rod 234 moves along the left handle of the tool, so that the left handle can be evenly stressed and convenient for adjustment. After the adjustment is completed, the push rod 234 is moved to the left, and then the positioning member 33 is pulled out to unload the tool, and then the turntable 32 is controlled by the origin switch of the turntable 32. The turntable 32 returns to its position and waits for the next tool. The problem that the existing adjustment method is difficult to accurately control the handle angle is solved, and the effect of being able to accurately adjust the tool handle angle is achieved. Example

[0037] The present application also discloses a method for using a tool handle angle adjustment device, comprising the following steps: Fixing, placing the tool on the turntable 32, and then selecting different numbers of positioning members 33 according to the right handle, placing the positioning members 33 on different pin holes on the turntable 32, so that the right handle of the tool can be fixed by the positioning members 33; Push, when the tool is fixed, the servo motor 21 rotates, and then drives the ball screw 231 connected by the coupling 22 to rotate in place, thereby driving the screw nut 233 on the ball screw 231 to move to the right, and synchronously controlling the push rod 234 connected to the screw nut 233 to move to the right, so that the front end roller 235 of the push rod 234 contacts the left handle of the tool, and the force point of the push rod 234 is on the same line as the force point of the outer positioning member 33, and the angle of the tool handle is adjusted by the push rod 234; Rotate, when the push rod 234 adjusts the angle of the tool handle, the turntable 32 is rotated synchronously to cooperate with the push rod 234 to adjust, so that the push rod 234 moves along the left handle of the tool, so that the left handle can be evenly stressed and easy to adjust; Return to the original position.
