The specific embodiment
The present invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, tool appliance for turning eccentric gear of press machine, comprise a tabular rectangle frock body 1, be provided with a plurality of bolts hole of fixing with the lathe rotary table on the frock body, be provided with verification axis hole 2 in frock body 1 center, a side at verification axis hole 2 is provided with positioning core axle 3, and verification axis hole 2 equates with the eccentric throw in the center of circle of eccentric gear 12 cylindricals with the rotation of eccentric body axle journal 14 with distance between positioning core axle 3.
As shown in Figure 1 and Figure 2, the edge of the frock body of the opposite side of the verification axis hole 2 on frock body 1 is provided with the teeth groove positioner, this device comprises teeth groove positioning seat 5, teeth groove positioning seat 5 is provided with bolt hole and the dowel hole 6 fixing with the frock body, teeth groove positioning seat 5 coordinates with alignment pin 4 on the frock body by dowel hole 6 and positions, and connects by teeth groove positioning seat set bolt 11-2 and realizes fixing with frock body 1; Have the through hole parallel with described frock body 1 symmetry axis in the inside of teeth groove positioning seat 5, be provided with internal thread in the through hole inside near the teeth groove positioning seat outside, through hole interpolation toothing groove locating shaft 7, through hole is inner to offset with teeth groove locating shaft 7 teeth groove locating shaft trip bolt 8 by extending into outside the teeth groove positioning seat.
As shown in Figure 2, verification axis hole 2, positioning core axle 3, teeth groove positioner are positioned at frock body 1 and grow on the parallel symmetry axis in limit.
As shown in Figure 1 and Figure 2, during use, this machine equipment with the first preliminary pretension of the workbench of frock body set bolt 11-1 and vertical lathe, is inserted verification axle (not shown) in verification axis hole 2, dial gauge is fixing on the knife bar of lathe.Start lathe, at this moment the workbench of lathe begins rotation, and the frock body 1 of preliminary pretension is also along with workbench is rotating on workbench.The gauge outfit of dial gauge is contacted with the cylindrical of verification axle, knife bar drives dial gauge and does circumference and move up and down, progressively adjust the position of frock body 1 on Lathe bench, the pivot that guarantees the verification axle is with after the pivot of Lathe bench is consistent, the frock body set bolt 11-1 that will be connected with vertical lathe workbench is fastening firmly, sheds the verification axle.with eccentric gear 12 and the assembling of frock body, positioning core axle 3 on frock body 1 is inserted in the axis hole of eccentric gear 12, because verification axis hole 2 equates with the eccentric throw in the center of circle of eccentric gear 12 cylindricals with the rotation of eccentric body axle journal 14 with distance between positioning core axle 3, the center, hole of verification axis hole 2 and the rotation of eccentric body axle journal 14 are positioned on the same vertical line, because the center, hole of verification axis hole 2 is consistent with the pivot of Lathe bench, therefore guaranteed that the rotation of eccentric body axle journal 14 and the rotation of Lathe bench are positioned on the same vertical line, thereby guaranteed the machining accuracy of eccentric body axle journal.
After the above-mentioned steps assembling is complete, by the teeth groove locating shaft trip bolt 8 in the teeth groove positioner that is adjusted at the 1 one side settings of frock body, teeth groove locating shaft 7 is inserted in the manufactured teeth groove of eccentric gear 12 tightly, eccentric gear 12 just can not freely rotate on frock body 1 like this, starts lathe this moment and can carry out turning processing.
the tool appliance for turning eccentric gear of press machine that provides in embodiment 1 can be guaranteed the machining accuracy of eccentric body axle journal, but find in actual applications, the eccentric gear that uses on the different pressures machine, the eccentric throw in the rotation of its eccentric body axle journal and the top circle center of circle mostly is fixing, but the diameter of top circle has difference, if the machine equipment that provides in embodiment 1 is provided, stretch out the distance of teeth groove positioning seat to adapt to the variation of top circle although can change the teeth groove locating shaft by adjustment teeth groove locating shaft trip bolt, but this adjusting range is limited, do not allow the teeth groove locating shaft long in processing simultaneously yet, because the teeth groove locating shaft is long, its intensity there is higher requirement, otherwise the teeth groove locating shaft can produce the bending distortion, affect machining accuracy.
The present embodiment is namely the further improvement of doing for the existing technical problem of eccentric gear tool appliance for turning that provides in solution embodiment 1.
As shown in Figure 3, Figure 4, the machine equipment that provides in the tool appliance for turning eccentric gear of press machine that provides in this embodiment and embodiment 1 is except the teeth groove positioner, and other parts structure, shape are consistent.
As shown in Figure 3, Figure 4, this teeth groove positioner is all to have the through hole parallel with described frock body symmetry axis in the inside of teeth groove positioning seat 5 with teeth groove positioner in embodiment 1, be provided with internal thread in the through hole inside near the teeth groove positioning seat outside, through hole interpolation toothing groove locating shaft 7, through hole is inner to offset with the teeth groove locating shaft teeth groove locating shaft trip bolt 8 by extending into outside the teeth groove positioning seat.
As shown in Figure 3, Figure 4, the improvement of this teeth groove positioner is the fixing and location of itself and frock body 1.
As shown in Figure 4, this teeth groove positioner comprises two T-slots 9 parallel with described frock body symmetry axis that arrange near the frock body edges, the T-slot 9 that teeth groove positioning seat set bolt 11-2 passes on the frock body is realized the fixing of teeth groove positioning seat and frock body with the bolt hole on the teeth groove positioning seat, after unclamping teeth groove positioning seat set bolt set bolt 11-2, teeth groove positioning seat 5 can slide before and after T-slot 9 is on frock body 1.
As shown in Figure 5, teeth groove positioning seat 5 is to adopt flat key to locate with the location of frock body 1, be specially, location flat key 10 is installed between two T-slots that arrange on the frock body, location flat key 10 is fixed by location flat key trip bolt 11-3 and frock body 1, be provided with the groove (not shown) parallel with described frock body symmetry axis in teeth groove positioning seat and the centre of frock body faying face, coordinate the location of realizing teeth groove positioning seat and frock body by the location flat key 10 on the frock body with groove on the teeth groove positioning seat.
during use, the installation of frock body 1 and lathe rotary table, consistent in checking procedure and embodiment 1, be not both, when setting-up eccentricity gear on the frock body, first unclamp teeth groove positioning seat set bolt 11-2 and teeth groove positioning seat 5 is pushed into the outermost of teeth groove positioner, after good eccentric gear to be installed, promote teeth groove positioning seat 5 to correct position, fastening teeth groove positioning seat set bolt 11-2, adjusting teeth groove locating shaft trip bolt 8 is inserted into teeth groove locating shaft 7 in the manufactured teeth groove of eccentric gear 12 tightly, start lathe this moment and can carry out turning processing.
