For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0020] The utility model will be described in detail below in conjunction with the drawings.
[0021] Referring to Figures 1-3 A terminal presser for wheel speed sensor production, comprising a press fitting mechanism 1, the press fitting mechanism 1 usually comprises upper pressing forceps, lower pressing forceps and power assembly (such as hydraulic cylinder) for driving upper pressing forceps lower, this is mature prior art, hereinafter will not be repeated;
[0022] A wire feeding mechanism 2 is fixedly installed on one side of the pressing mechanism 1. The wire feeding mechanism 2 includes a mounting frame 201. A support platform 202 is fixedly installed on the mounting frame 201. A receiving groove for placing wires is opened on the support platform 202. Two rotating cylinders 203 are arranged on the side of the mounting frame 201 near the receiving groove of the pressing mechanism 1. The two rotating cylinders 203 are rotatably engaged with the mounting frame 201. A pusher wheel 204 is fixedly installed on each of the two rotating cylinders 203. The two pusher wheels 204 are provided with symmetrically distributed notches. A first driving mechanism is fixedly installed on the mounting frame 201. The first driving mechanism is used to drive the two rotating shafts to rotate synchronously in opposite directions.
[0023] The mounting bracket 201 has a stabilizing mechanism 3 fixedly installed at the pressing point of the pressing mechanism 1. The stabilizing mechanism 3 includes a slide rod 301 fixedly installed on the mounting bracket 201. An upper stabilizing plate 302 and a lower stabilizing plate 303 are symmetrically distributed and slidably sleeved on the slide rod 301. A second driving mechanism is fixedly installed on the mounting bracket 201. The second driving mechanism is used to drive the upper stabilizing plate 302 and the lower stabilizing plate 303 to move closer or further away from each other. A stabilizing groove 304 is opened on the opposite side of the upper stabilizing plate 302 and the lower stabilizing plate 303. The stabilizing groove 304 is arc-shaped and adapted to the shape of the wire. Guide slopes 305 are provided on both sides of the stabilizing groove 304.
[0024] A terminal vibration feeding device is also installed on the side of the pressing mechanism 1 away from the infeeding mechanism 2. This is a mature existing technology, which has been described in the background technology section and will not be repeated here.
[0025] Additionally, the first drive mechanism includes a first motor fixedly mounted on the mounting bracket 201. The output shaft of the first motor is fixedly connected to one of the rotating drums 203. Gears 205 are coaxially fixed on both rotating drums 203, and the two gears 205 mesh with each other.
[0026] When the first motor starts, the output shaft of the first motor drives the rotating drum 203 fixedly connected to it to rotate. Since the two gears 205 mesh with each other, the other rotating drum 203 will rotate synchronously in the opposite direction, thereby cooperating to drive the push wheel 204 to push the wire forward. The first drive mechanism has a simple structure and is stable and reliable.
[0027] The second drive mechanism includes a second motor fixedly mounted on the mounting frame 201. A bidirectional lead screw 306 is fixedly mounted on the output shaft of the second motor. Both ends of the bidirectional lead screw 306 are rotatably engaged with the mounting frame 201. An upper stabilizing plate 302 and a lower stabilizing plate 303 are symmetrically sleeved on both ends of the bidirectional lead screw 306 through lead screw nuts. The bidirectional lead screw 306 and the slide bar 301 are located at the ends of the upper stabilizing plate 302 and the lower stabilizing plate 303, respectively.
[0028] When the second motor starts, the output shaft of the second motor drives the bidirectional lead screw 306 to rotate. Since the threads at both ends of the bidirectional lead screw 306 are in opposite directions, the upper stabilizing plate 302 and the lower stabilizing plate 303 will move closer or further away from each other along the slide bar 301 as the bidirectional lead screw 306 rotates. The bidirectional lead screw 306 transmission has high control precision and can accurately control the moving distance of the upper stabilizing plate 302 and the lower stabilizing plate 303. The distribution of the bidirectional lead screw 306 and the slide bar 301 enables the upper stabilizing plate 302 and the lower stabilizing plate 303 to move stably when driven.
[0029] Both push rollers 204 are covered with a rubber layer 206. The rubber layer 206 has a large coefficient of friction, which can increase the friction between the push roller 204 and the wire, ensuring that the push roller 204 can stably and reliably push the wire forward and avoid slippage. In addition, the rubber layer 206 has a certain degree of elasticity and softness, which can play a buffering and protective role during contact and friction with the wire, reducing damage to the surface of the wire.
[0030] The rotating drum 203 is equipped with a directional indicator 207. When workers place wires, the directional indicator 207 can provide clear instructions and intuitive references for workers, enabling them to quickly and accurately place the wires in the correct position and further reduce the difficulty of operation.
[0031] Working principle: When using this terminal crimping machine, the wire is first placed in the receiving groove of the support platform 202, so that the front end of the stripped wire is located between the two rotating drums 203. Then, the first drive mechanism is started, which drives the two rotating drums 203 to rotate synchronously in opposite directions. During the rotation of the rotating drums 203, the pusher wheel 204 set on the rotating drum 203 contacts the wire. Through the friction between the pusher wheel 204 and the wire, the wire is pushed forward.
[0032] When the wire is pushed between the upper stabilizing plate 302 and the lower stabilizing plate 303, the second drive mechanism starts working, driving the upper stabilizing plate 302 and the lower stabilizing plate 303 to move closer to each other. The stabilizing grooves 304 on the upper stabilizing plate 302 and the lower stabilizing plate 303 gradually come into contact with the wire from both sides, correcting the position of the wire's front end. This ensures that as the wire continues to be conveyed forward, the exposed copper wire at the front end can be smoothly inserted into the terminal already placed on the lower clamp. Subsequently, the pressing mechanism 1 starts, and the upper clamp moves down to work in conjunction with the lower clamp to complete the pressing process.
[0033] After pressing is completed, the first drive mechanism drives the two rotating drums 203 to rotate in opposite directions, so that the wire with the pressed terminal can be moved back by the push wheel 204. At the same time, the second drive mechanism drives the upper stabilizing plate 302 and the lower stabilizing plate 303 to move away from each other, so as to avoid the terminal being blocked by the upper stabilizing plate 302 and the lower stabilizing plate 303 during the retraction process. When the two push wheels 204 rotate to no longer contact the wire, the distance between the two notches is sufficient to remove the pressed wire. At this time, the worker can put in the next wire to be pressed and continue the next round of pressing operation.
[0034] This utility model, through the setting of the wire inlet mechanism 2 and the stabilizing mechanism 3, enables the wire to be automatically pushed to the terminal and accurately inserted into the terminal, avoiding the safety hazards caused by direct operation by workers.
[0035] The first and second motors of this invention are both electrically connected to the controller to achieve coordinated operation. The controller's control circuit can be easily programmed by those skilled in the art, and the power supply is also common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
