For a clearer understanding of the concepts of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
Example 1:
referring to fig. 3 and 4, the chain pin 6 is inserted into the counter bore 102 of the pallet 1, then the small column cap 502 of the cylindrical guide pin 5 is fastened to the threaded hole 101 of the pallet 1, the sliding tray 2 passes through the large column cap 502 of the cylindrical guide pin 5 through the matching kidney-shaped hole 201, is laid on the pallet 1, and is fastened to the flat pad 8 through the bolt 7. The height of the large cylinder 502 is larger than the thickness of the sliding tray 2, so that after the bolt 7 is installed and fastened, the flat pad 8 is in contact with the end face of the large cylinder head 502, namely, a gap exists between the flat pad 8 and the sliding tray 2. At this time, the sliding tray 2 is pushed to slide along the length direction of the kidney-shaped hole 201.
Referring to fig. 2 and 5, a part of the positioning pin a9 is screwed into the cylindrical hole 202 of the sliding tray, the pin hole 301 of the transition block 3 is matched with the positioning pin 9 exposed outside, at this time, the transition block 3 is laid on the sliding tray 2, and then the fastening bolt 10 passes through the through hole 302 to be matched with the threaded hole 203, so as to fasten the transition block 3 and the sliding tray 2. The positioning pin B11 is partially screwed into the positioning hole 305 of the transition block 3, the radial positioning hole 404 of the tool 4 is matched with the positioning pin B11 for installation, then the boss is embedded into the through cavity 303, and the tool 4 is radially fixed at the moment. The handle 12 is then screwed into the threaded hole 304 of the transition block 3 until the top end of the handle 12 contacts the tapered surface 402 of the tooling 4. Since the tapered surface 402 is small at the top and large at the bottom, the tool is also fixed in the axial direction.
Example 2:
referring to fig. 6, on the basis of embodiment 1, a conical surface 402 provided on a boss of the tool 4 is changed into a blind hole 403 matched with a handle. The handle 12 is screwed into the threaded hole 304 of the transition block 3 until the top end of the handle 12 is screwed into the blind hole 403 of the tool 4, and at the moment, the axial position of the tool is fixed.
According to the embodiment, when the tool 4 is installed, the boss is only required to be embedded into the through cavity 303 of the transition block 3, the positioning pin B11 is inserted, and the handle 12 is screwed; when the handle 12 is replaced or disassembled, the handle is only required to be loosened and pulled out along the axial direction of the positioning pin B11. The operation is simple and quick, and the positioning is accurate.
Example 3:
referring to fig. 2 and 7, an error-proofing detection switch 15 is installed on the left side of the horizontal slideway of the stacker, and when the tooling pallet 16 is installed and operated to the position a shown in the figure through the chain pin 6 and the chain in a matching manner, the detection switch 15 works and is identified through a groove 401 on the tooling 4 on the tooling pallet 16. If the workpiece 13 is placed in the correct direction, the groove 403 of the tool is through at the moment, and the tool tray 16 normally slides to the right, namely, to the position B; if the workpiece 13 is placed in the wrong direction, the groove 403 of the tool is shielded at the moment, the detection switch 15 sends a signal to the system, the system gives an alarm to prompt that the workpiece is placed in the wrong direction, and the workpiece needs to be placed again later.
A detection position is arranged at the position B on the right side of the stacker, a detection switch 17 is installed at the detection position, when the tooling tray passes through the detection of the error-proof detection switch 15, the tooling tray slides to the position B, and the detection switch 17 detects the detection piece 13 on the tooling tray to realize the in-place stop of primary positioning. After the tooling pallet 16 is stopped in place, the positioning structure at the lower end of the slide way extends out of the positioning pin shaft, and the positioning pin shaft is matched with the pin inlet hole 204 of the sliding pallet through the kidney-shaped hole 103, so that the secondary correction and positioning of the sliding pallet are realized. Because the stacker horizontal motion adopts chain drive, long-time work chain can become flexible and lengthen, in order to avoid going into the round pin difficulty this moment, slidable slip tray 2 carries out position control. To avoid the difficulty of pin insertion, the length of the pin insertion elongated hole 103 on the supporting plate 1 is greater than that of the kidney-shaped hole 201 on the sliding tray 2, so as to ensure the smooth pin insertion.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
