As shown in Figures 2 to 4, a kind of basis is also disclosed in the present embodiment can be carried out the flat of precise positioning processing as described above On head machine, the processing method of device for discharging, comprising the following steps:
1), control electric machine 11 acts, and three or three or more lower folders are driven by transmission belt one and transmission belt two Tool 1 is mobile;
2), when sensor 5 detects a lower fixture 1 close to Working position B, control lifting positioning linkage 12 is determined Position bar extends through support plate 8 and is inserted into the locating slot 13 of one lower fixture 1, and controls electric machine 11 and stop work Make, under the action of inertia, one lower fixture 1 continues to move to locating slot 13 and positioning until one lower fixture 1 Bar is in contact to form position limiting structure, so that one lower fixture 1 is accurately located on Working position B, then controls folder Have that 3 vertical pushings are mobile, to using upper fixture 3 and be moved to the lower fixture 1 of Working position match will be under at Working position Pipe fitting in fixture 1 is fixedly clamped;
3) tack processing, is carried out to the pipe fitting on the one lower fixture 1 being located on Working position;
1) the step of execution the 3) is returned again to after step when completing the, is so recycled, until the tack for completing all pipe fittings adds Work operation.
In the present embodiment, it when upper fixture 3 and is moved to the lower fixture 1 of Working position in the 2) step and matches and will add After pipe fitting in the lower fixture 1 in the station place of setting is fixedly clamped, then the locating rod retraction of lifting positioning linkage 12 is controlled from described It is extracted out in the locating slot 13 of one lower fixture, then executes the 3) step again.Locating rod is extracted out from locating slot before processing, It is because having very big torsion when processing, operation in this way can extend the service life of locating rod.
Locating rod 2) stretched out in step is inserted into locating slot from locating slot openning shape one end.
Embodiment 2: as shown in figure 17, compared with Example 1, the difference is that: locating slot 13 is arranged at lower fixture bottom On the bottom of plate 111, the both ends of locating slot 13 are closed, and locating rod is in contact to be formed with the side groove sidewall of locating slot 13 Position limiting structure;
Locating rod 2) stretched out in step is inserted into locating slot from the notch of locating slot 13.When sensor detects When to a lower fixture at Working position B, the locating rod of control lifting positioning linkage passes through support plate from locating slot Notch is inserted into the locating slot of one lower fixture and controls electric machine stopping movement, when electric machine stopping acts Afterwards, under the action of inertia, transmission belt one and transmission belt two also will drive lower fixture continuation mobile a certain distance forward, move During dynamic, the locating rod of stretching can be in contact with the side groove sidewall of the locating slot of one lower fixture, to form limit Bit architecture.
To sum up, by locating rod with locating slot match, enable the present invention to be located at Working position at lower fixture It is accurately positioned, so that each lower fixture can be accurately located on prior designed Working position to lower fixture In pipe fitting carry out tack processing, to improve the machining accuracy and processing quality of chamfering machine.By the way that shape open at one end is arranged Locating slot, design difficulty is reduced, to reduce on chamfering machine, the manufacturing cost of device for discharging.By at lower fixture bottom It is arranged on the bottom of plate and keeps away bits slot with what guiding groove was connected, lower fixture is enabled to avoid falling and propping up when support plate moves Some machining chips on fagging, to ensure that the normal movement of lower fixture.By the way that lower fixture is designed to separate structure, when When needing to process the pipe fitting of different size, as long as replacement is carried out to lower chuck body, to improve of the invention Versatility.It is designed by structure, when so that being assembled between axis one, axis one, axis two, driving wheel and driven wheel and support base, It can be more convenient.By setting shield one and shield two, can prevent machining chips fall to transmission belt, driving wheel and Between driven wheel, being normally carried out for tack processing ensure that.
Above embodiments are used for illustrative purposes only, rather than limitation of the present invention, the technology people in relation to technical field Member without departing from the spirit and scope of the present invention, can also make a variety of changes or convert, therefore is all equivalent Technical solution also should belong to protection scope of the present invention, and protection scope of the present invention should be limited by each claim.
