[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, a gear assembly press-fit error-proofing tool comprises a press-fitting machine 1, a gear transmission mechanism 2 that moves along the width direction of the press-fitting machine 1, and a mounting seat transmission mechanism 3 that moves along the length direction of the press-fitting machine 1, including an error-proofing tool 4 disposed in the press-fitting machine 1, comprising:

[0026] A fixing base 41 is fixedly installed in the press 1 and located at the end of the gear transmission mechanism 2, and a trigger slider 46 is slidably installed on the fixing base 41;

[0027] A rotating base 47 is rotatably mounted on the fixing base 41 and locked by the trigger slider 46 to be in close contact with the bottom of the fixing base 41;

[0028] An arc-shaped rod 44 is movably arranged and rotates relative to the fixed base 41, and is slidably engaged with the tooth groove of the helical gear;

[0029] The arc rod 44 is driven to move downward and rotate, and the rotation direction is consistent with the inclination direction of the tooth groove of the helical gear, and there is a triggering position for pushing the trigger slider 46 in the rotation stroke of the arc rod 44.

[0030] Specifically, the mounting seat transmission mechanism 3 is located below the anti-error inspection fixture 4, and the mounting seat assembled thereon is located at the vertical projection center of the fixed seat 41 during the press-fitting process. A torsion spring is provided on the rotating base 47 to keep it close to the bottom of the fixed base 41, and an opening is provided on the rotating base 47 for avoiding the mounting seat.

[0031] Furthermore, the gear transmission mechanism 2 transmits the helical gear to the fixed seat 41 at the end. The default position of the arc rod 44 is higher than the upper surface of the helical gear, and then the arc rod 44 is driven to move downward. Since the arc rod 44 is guided by the tooth groove of the helical gear and rotates, the rotation direction of the arc rod 44 is consistent with the inclination direction of the tooth groove. When the helical gear is placed in the correct direction, the inclination direction of the tooth groove is always fixed. Therefore, the rotation direction of the arc rod 44 is fixed, and the trigger slider 46 is located in this direction. The arc rod 44 pushes the trigger slider 46 during the rotation stroke. This position is the trigger position. The spring 462 provided on the trigger slider 46 is stretched, and the trigger slider 46 no longer locks the rotating base. 47, and then the pressure rod of the press 1 moves downward, and the pressure rod pushes the bevel gear downward, and the bevel gear presses the rotating base 47 downward and overcomes the elastic force of the torsion spring on the rotating base 47, so that the rotating base 47 rotates downward and avoids the mounting seat through the opening, and the bevel gear contacts the mounting seat under the pressure of the pressure rod and is pressed onto the mounting seat to complete the press fitting; and when the bevel gear is placed in the wrong direction, the arc rod 44 rotates in the opposite direction. At this time, the arc rod 44 cannot push the trigger slider 46, so that the rotating base 47 remains locked, and when the pressure rod pushes the bevel gear downward, the rotating base 47 will not rotate downward, so the bevel gear will not be assembled on the mounting seat in the wrong direction.

[0032] In the above technology, through the setting of the arc rod 44, when the helical gear is placed in the wrong direction, the rotating base 47 remains locked. When the pressure rod pushes the helical gear downward, the rotating base 47 will not rotate downward. Therefore, the helical gear will not be assembled on the mounting seat in the wrong direction. In addition, this device cooperates with the gear transmission mechanism 2 and the mounting seat transmission mechanism 3 to realize the direction detection of a large number of helical gears, which is more convenient.

[0033] As an embodiment further provided by the present invention, a clamping seat 49 is provided on the rotating base 47 , and a clamping member 461 that is clamped and engaged with the clamping seat 49 is provided on the trigger slider 46 .

[0034] The spring 462 is stretched, and then the arc rod 44 is driven to move upward and does not contact the anti-slip pad 411, so that the arc rod 44 can rotate freely. The deformation of the spring 462 is restored and the arc rod 44 is retracted into the fixed seat 41, and at the same time, the clamping piece 461 is clamped with the card seat 49 along the slide groove.

[0035] As another embodiment further provided by the present invention, the trigger slider 46 is located at the first end of the arc rod 44, and a pressure detection component for detecting the pressure at the second end of the arc rod 44 is provided on the fixing seat 41, and the pressure detection component is electrically connected to the buzzer 48.

[0036] Specifically, the pressure detection component and the trigger slider 46 are symmetrically arranged on both sides of the fixed seat 41. When the arc rod 44 slides with the incorrectly placed helical gear tooth groove, the arc rod 44 slides in the direction of the pressure detection component, applies pressure to the pressure detection component and triggers the buzzer 48, which prompts the staff to flip the helical gear through the buzzer.

[0037] As another embodiment further provided by the present invention, the pressure detection assembly includes an anode metal sheet 481 and a cathode metal sheet 482 fixedly disposed on the fixing seat 41 , and the cathode metal sheet 482 is pressed against the anode metal sheet 481 .

[0038] Specifically, the anode metal sheet 481 and the cathode metal sheet 482 both have a certain degree of elasticity, and both are located on the circuit of the buzzer 48. When the arc rod 44 slides in the direction away from the trigger slider 46, the second end of the arc rod 44 gradually approaches the pressure detection component and abuts against the cathode metal sheet 482, causing the cathode metal sheet 482 to bend under pressure and contact with the anode metal sheet 481, thereby connecting the circuit and causing the buzzer 48 to emit a buzzing sound.

[0039] As another embodiment further provided by the present invention, it also includes an electric telescopic rod 42 for driving the arc rod 44 to move, the output end of which is fixedly provided with a slide 43 that slides with the fixed seat 41, and the arc rod 44 is rotatably set in the slide 43.

[0040] Specifically, the electric telescopic rod 42 is preset with a program, and the electric telescopic rod 42 can be set to extend and retract at fixed intervals through a timing program, or the electric telescopic rod 42 can be driven to extend and retract by transmitting a signal through a wireless device, or other driving methods known to those skilled in the art can be used.

[0041] The slide 43 is driven by the electric telescopic rod 42 to move up and down, and the arc rod 44 rotates in the slide 43. When the arc rod 44 slides to the same height as the anti-slip pad 411, the arc rod 44 stops moving under the action of friction.

[0042] As another embodiment further provided by the present invention, a plurality of rotating teeth 45 are rotatably arranged in a circumferential array on the arc rod 44 and engage with the teeth of the helical gear.

[0043] Specifically, when the helical gear is transported to the inside of the fixed seat 41 by the gear transmission mechanism 2, it will abut against the inner wall of the fixed seat 41. The rotating tooth 45 is located on the arc rod 44 and above the helical gear. When the arc rod 44 is driven downward, the rotating tooth 45 is driven downward and slides with the teeth of the helical gear, so that the rotating tooth 45 rotates to the same angle as the inclination angle of the teeth. Then, when the arc rod 44 is moved downward again, the arc rod 44 is rotated by the sliding cooperation between the rotating tooth 45 and the teeth, and the rotation direction is consistent with the inclination direction of the tooth groove.

[0044] Working principle: The gear transmission mechanism 2 transmits the helical gear to the fixed seat 41 at the end. The default position of the arc rod 44 is higher than the upper surface of the helical gear. Then the arc rod 44 is driven to move downward, driving the rotating latch 45 to move downward and slidingly cooperate with the teeth of the helical gear, so that the rotating latch 45 rotates to the same angle as the inclination angle of the teeth. Then, when the arc rod 44 is moved downward again, the arc rod 44 is rotated by the sliding cooperation between the rotating latch 45 and the teeth. The rotation direction is consistent with the inclination direction of the tooth groove. When the helical gear is placed in the correct direction, the inclination direction of the tooth groove is always fixed, so the rotation direction of the arc rod 44 is consistent. The spring 462 provided on the trigger slider 46 is stretched, and the trigger slider 46 no longer locks the rotating base 47. Then the pressure rod of the press 1 moves downward, and the pressure rod pushes the bevel gear downward, and the bevel gear presses the rotating base 47 and overcomes the elastic force of the torsion spring on the rotating base 47, so that the rotating base 47 rotates downward and avoids the mounting seat through the opening. The bevel gear is in contact with the mounting seat under the pressure of the pressure rod and is pressed onto the mounting seat to complete the press fitting.

[0045] After the bevel gear is located under the rotating base 47, the rotating base 47 is not pushed by the bevel gear. When the elastic force of the torsion spring is released, the rotating base 47 returns to be close to the bottom of the fixed base 41, and the arc rod 44 is kept in place by the friction force of the anti-slip pad 411. At this time, the trigger slider 46 is still in a state of being pushed by the arc rod 44, and the spring 462 is stretched, and then drives the arc rod 44 to move upward and does not contact the anti-slip pad 411, so that the arc rod 44 can rotate freely. The deformation of the spring 462 is restored and pulls the arc rod 44 back into the fixed base 41, while driving the clamping piece 461 to engage with the clamping base 49 along the slide groove.

[0046] When the helical gear is placed in the wrong direction, the arc rod 44 rotates in the opposite direction. At this time, the arc rod 44 cannot push the trigger slider 46, so that the rotating base 47 remains locked. When the pressure rod pushes the helical gear downward, the rotating base 47 does not rotate downward. When the arc rod 44 slides in the direction away from the trigger slider 46, the second end of the arc rod 44 gradually approaches the pressure detection assembly and abuts against the cathode metal sheet 482, so that the cathode metal sheet 482 is bent under pressure and contacts the anode metal sheet 481, thereby connecting the circuit, causing the buzzer 48 to buzz, and the buzzing prompts the staff to turn over the helical gear.

[0047] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
