The transportation method comprises the following specific steps:
s1, when in operation, a workpiece 1 is placed on a positioning mechanism to be clamped;
s2, starting a driving mechanism to carry out a transfer process of the workpiece 1;
s3, in the transferring process, the detection mechanism calibrates the position of the machining hole 1-1 in the workpiece 1 relative to the positioning mechanism and then fixes the position;
s4, after the detection mechanism finishes the calibration procedure, the workpiece 1 is guided by different transfer paths according to the calibrated degree of the machined hole 1-1.
Working principle: when the device works, a workpiece 1 is placed on a sliding plate 2-2 in a positioning mechanism and clamped by a clamp 2-3, so that the workpiece 1 is fixed on the sliding plate 2-2, then a driving motor 3-1 is started to drive a driving wheel 3-3, so that a sliding shell 2-1 moves rightwards along a track 5-1, the sliding shell 2-1 drives the sliding plate 2-2 which is movably connected inside the sliding shell to move rightwards, the sliding plate 2-2 drives the workpiece 1 to synchronously move rightwards (in actual working, in order to enable the sliding plate 2-2 to slide along the sliding shell 2-1 due to inertia reasons, so as to influence the working of a subsequent detection mechanism, the sliding plate 2-2 and the sliding shell 2-1 can be increased by increasing the friction force factor between the sliding plate 2-2 and the sliding shell 2-1, or the sliding shell 2-1 can always keep the trend of returning to the central position of the sliding shell 2-1 while sliding in the sliding shell 2-1 through an elastic piece), the sliding shell 2-1 moves rightwards through an elastic telescopic rod 4-1, so that the detection mechanism moves rightwards along the track 5-1, and the detection mechanism moves along a track 5-1 along a track (a second track 7 and a second track in the track 7-8 is a horizontal track in a sliding track-5-7 and a horizontal track is provided by a horizontal track in a positioning mechanism;
in the process, (as shown in figure 1) a slide bar 4-3 in the detection mechanism moves downwards along the track of the track 5-1, and a slide bar 4-2-1 in the detection mechanism drives a lower pressing plate 4-2 to move downwards along the track of a third track 8 and keep relative static with the slide bar 4-3 until the lower end face of the locating pin 4-4 reaches the upper end face of the workpiece 1; (as shown in figure 2), the track height of the rear track 5-1 in the vertical direction is unchanged, the track height of the third track 8 in the vertical direction continuously moves downwards, so that the lower pressing plate 4-2 is driven to continuously move downwards, the spring 4-5 is extruded in the process of moving the lower pressing plate 4-2 downwards, and the spring 4-5 downwards extrudes the positioning pin 4-4;
theoretically, if the position and the size of the machining hole 1-1 in the workpiece 1 are the same as the theoretical values, the positioning pin 4-4 should be opposite to the machining hole 1-1, and under the downward extrusion force of the spring 4-5, the positioning pin can be inserted into the machining hole 1-1 without obstruction and drive the slide rod 4-3 to move downward;
in practice, the position and size of the machined hole 1-1 in the workpiece 1 deviate from the theoretical values; and in practice, the degree of deviation in the position and size of the machined hole 1-1 in the workpiece 1 is divided into three types:
case one: the processing hole 1-1 is aligned with the positioning pin 4-4 under the initial state or through the action of the guide angle 4-4-1, and the positioning pin 4-4 can be completely inserted into the processing hole 1-1 in the downward moving process of the positioning pin 4-4, in this case, the actual position of the processing hole 1-1 relative to the equipment can reach a preset position (i.e. the position of the processing hole 1-1 relative to the equipment after the workpiece 1 is installed to the equipment under the ideal state) under the action of the positioning pin 4-4, and further, the workpiece 1 can be directly processed after being transported to the next processing station along with the equipment; in the process of downward movement of the positioning pin 4-4, the side edge of the processing hole 1-1 is contacted with the guide angle 4-4-1 at the lower end of the positioning pin 4-4 and is extruded, the further guide angle 4-4-1 drives the processing hole 1-1 to be aligned with the positioning pin 4-4 through extrusion force, and simultaneously drives the sliding plate 2-2 to slide in the sliding shell 2-1; the positioning pin 4-4 is completely inserted into the processing hole 1-1, the sliding rod 4-3 which is correspondingly and fixedly connected with the positioning pin 4-4 moves downwards, and the height of the upper end of the sliding rod 4-3 is within the vertical height range of the third boss 5-2-3;
and a second case: the machining hole 1-1 cannot be completely aligned with the positioning pin 4-4 through the action of the guide angle 4-4-1, and further, the positioning pin 4-4 cannot be completely inserted into the machining hole 1-1, in this case, the actual position of the machining hole 1-1 relative to equipment still reaches a preset position under the action of the positioning pin 4-4, and the machining hole 1-1 cannot be directly transported to a next machining station for machining along with the equipment, so that whether the offset of the machining hole 1-1 can meet the normal use or not needs to be judged manually; in this case, since the positioning pin 4-4 is not completely inserted into the processing hole 1-1, the downward movement amount of the positioning pin 4-4 is smaller than that of the first case, and thus the downward movement amount of the slide bar 4-3 is smaller, the height of the upper end of the slide bar 4-3 is higher than that of the first case, and in this embodiment, the height of the upper end of the slide bar 4-3 is within the vertical height range of the second boss 5-2-2.
And a third case: the position deviation of the machining hole 1-1 relative to the positioning pin 4-4 is too large, the positioning pin 4-4 can only be inserted into the machining hole 1-1 to a smaller depth under the condition of two relative conditions, or can not be inserted into the machining hole 1-1 at all, in this case, the deviation of the machining hole 1-1 is too large, the workpiece 1 is directly judged to be a defective product, and the workpiece is transported to a scrapping or repairing process; because the depth of the positioning pin 4-4 inserted into the processing hole 1-1 is smaller than that of the second case, the corresponding downward movement amount of the positioning pin 4-4 is smaller, and the height of the upper end of the sliding rod 4-3 is higher than that of the second case, in the embodiment, the height of the upper end of the sliding rod 4-3 in the third case is within the vertical height range of the first boss 5-2-1;
after the positioning pin 4-4 finishes the downward movement work, the sliding shell 2-1 continues to move right, the track height of the first sliding rail 7-1 starts to tighten, the clamping plate 2-4 is extruded along with the tightening of the first sliding rail 7-1 and moves downward, and the bottom surface of the sliding shell 2-1 is matched to firmly clamp the sliding plate 2-2, so that the position of the workpiece 1 is fixed;
then the equipment is operated to the position of the guide boss 5-2, and different operation paths are carried out according to different conditions of the workpiece 1:
case one: (as shown in fig. 3), the upper end of the sliding rod 4-3 is in the height range of the third boss 5-2-3, the sliding rod 4-3 directly guides the equipment to move to the next station (processing station) along the track of the third boss 5-2-3, at this time, the third baffle 5-3-3 plays a role in stabilizing the track of the sliding rod 4-3, preventing the sliding rod 4-3 from separating from the third boss 5-2-3, and meanwhile, the paths of the first sliding rail 7-1, the second sliding rail 7-2 and the third sliding rail 8 are paved along the advancing track of the sliding rod 4-3 so as to ensure the relative rest of all components in the equipment, so that the processing hole 1-1 enters the next processing station to be directly processed without adjusting the position again in a state of maintaining the ideal position of the relative equipment, and a large amount of working hours are saved in the whole production flow;
and a second case: (as in FIG. 2) the upper end of the slide bar 4-3 is within the height of the second boss 5-2-2. When the slide bar 4-3 is directly guided by the slide bar 4-3 to move along the track of the second boss 5-2-2 to the next station (manual processing station), at this time, the third baffle 5-3-3 slides rightward under the extrusion of the slide bar 4-3 (when the slide bar 4-3 moves to the second boss 5-2-2, the second boss 5-2-2 extrudes the slide bar 4-3 to make the slide bar 4-3 move along the track of the second boss 5-2-2, and at the same time, when the slide bar 4-3 moves along the track of the second boss 5-2-2, the slide bar 4-3 extrudes the third baffle 5-3-3, but since the third baffle 5-3 is only elastically slidably connected to the device and the second boss 5-2-2 is fixed to the device, the third baffle 5-3 moves along the track of the second boss 5-2-2, the third baffle 5-3 slides along the track of the second boss 5-3, and the slide bar 4-3 slides along the track of the second boss 5-2-2 is directly separated from the track of the second boss 2-2, and the slide bar 4-3 moves along the track of the second boss 2-2 to the second boss 2-2 directly along the track of the second boss 5-2-2 and moves directly along the track of the second boss 2-2 to the slide bar when the slide bar 4-3-3 moves along the track to the second boss 2-2 to the next station (and moves directly along the slide bar 2-3 to the next rail and moves directly along the lower baffle 2 to the next baffle 3). The associated positioning need not be maintained anymore);
and a third case: (as in fig. 1) the upper end of the slide bar 4-3 is within the height range of the first boss 5-2-1, and similarly to the second case, the slide bar 4-3 is moved to the next station (reject station) along the track of the first boss 5-2-1.
