The working process of the bidirectional telescopic transmission device provided by the embodiment of the utility model is as follows: firstly, a white car body needing to be welded is placed on a second sliding plate 6, a workpiece is positioned and clamped by using workpiece clamping mechanisms 28 arranged at two ends of the second sliding plate 6, and then the motor 8 can be controlled to work through a control system of the device:
when the motor 8 rotates positively, the driving gear 9 is driven by the reduction gearbox 7 to rotate positively, the driving gear 9 drives the driving rack 10 meshed with the driving gear 9 and the first sliding plate 4 fixedly connected with the driving rack 10 to move leftwards, when the first sliding plate 4 moves leftwards, the driven gear 11 rotatably supported on the other side of the driving gear 4 also moves along with the driving gear, but the lower part of the driven gear 11 is meshed with the lower rack 13 fixedly arranged on the bottom plate 1, so that the driven gear 11 moves leftwards along with the first sliding plate 4 and rotates under the action of the lower rack 13, the upper rack 12 meshed with the driven gear is driven to do linear motion relative to the driven gear 11 (namely the first sliding plate 4), and the upper rack 12 is fixedly connected with the second sliding plate 6, namely, when the motor 8 rotates positively, the first sliding plate 4 slides leftwards relative to the bottom plate 1, and the second sliding plate 6 also slides leftwards relative to the first sliding plate 4, and the superposition of the movement distances of the two sliding plates is the maximum stroke of the transmission device for driving a workpiece to move leftwards;
when the motor 8 is reversed, the above actions are reversed, the first sliding plate 4 slides rightwards relative to the bottom plate 1, and the second sliding plate 6 also slides rightwards relative to the first sliding plate 4, and the superposition of the movement distances of the two sliding plates is the maximum stroke of the transmission device for driving the workpiece to move rightwards;
compared with the traditional transmission device with the same specification, the device has the advantage of driving the workpiece to move in two directions, and simultaneously, the device has larger stroke because the maximum stroke of the workpiece moving in two directions is the superposition of the movement strokes of the two sliding plates;
in the non-working state, the first slide plate 4 and the second slide plate 6 stay in place, in this state, the zero point pointer 26 on the base 1 just points to the zero point position in the scale 27 on the second slide plate 6, and meanwhile, the first left photoelectric switch 14 is located at the opposite position to the first left triggering block 17 on the second slide plate 6, and the first right photoelectric switch 20 is also located at the opposite position to the first right triggering block 23 on the second slide plate 6, that is, when the first left photoelectric switch 14 and the first right photoelectric switch 20 are triggered at the same time, this means that the device is in the non-working state of returning to zero; at this time, a worker can observe the zero point pointer 26 and the scale on the scale 27, and if deviation exists, the worker needs to adjust in time;
when the second sliding plate 6 moves to the left maximum stroke, the second left photoelectric switch 15 is just triggered by the second left triggering block 18, and after receiving a signal sent by the second left photoelectric switch 15, the control system controls the motor 8 to stop working, and at the moment, the left safety triggering block 19 is not in contact with the left safety switch 16; if the motor 8 has a problem, and the second sliding plate 6 continues to move leftwards, the left safety trigger block 19 collides with the left safety switch 16, and after the left safety switch 16 is triggered, the motor 8 is immediately controlled to be powered off, so that the device stops acting, and the problem caused by the fact that the second sliding plate 6 exceeds the maximum left travel is prevented;
similarly, the right detection assembly may also be used to detect whether the second slide plate 6 is moving to the right maximum stroke, and also has the function of preventing the second slide plate 6 from exceeding the right maximum stroke.
