Specific embodiment

As shown in Figure 1, 2, the utility model discloses a kind of gear fixing tools, comprising: pedestal 1, left vertical block 2, the right side are vertical Block 3, transverse slat 4, cylinder 5, briquetting 6, locating piece 7, shaft 8, base station 9, locating shaft 10, annular tray 11, the left vertical block 2, the right side Vertical block 3 is fixed in vertically respectively at left and right sides of 1 upper surface of pedestal, and 4 level of transverse slat is fixed in left vertical block 2 and right vertical block 3 Top, the cylinder 5 are mounted in the middle part of 4 upper surface of transverse slat, and 5 piston rod of cylinder is passed down through end affixed one after transverse slat 4 A briquetting 6, the briquetting 6 is horizontally disposed, an affixed locating piece 7 on the left of 6 lower end surface of briquetting, and 8 lower end of shaft is logical It crosses in the middle part of bearing and 1 upper surface of pedestal and is rotatablely connected, the shaft 8 is vertically arranged, the upper end and 9 lower end of base station of the shaft 8 Face center is affixed, a vertical affixed locating shaft 10 at the 9 upper surface center of base station, and the annular tray 11 is sleeved on positioning On the downside of 10 outer peripheral surface of axis, the locating shaft 10 is placed in the underface of briquetting 6.

The locating piece 7 is arc-shaped structure, is provided on the intrados of locating piece 7 and engages with what work gear to be added was meshed Tooth 71.

The diameter of the locating shaft 10 is consistent with gear center hole internal diameter to be processed.

10 height of locating shaft of 11 upside of annular tray is consistent with gear height to be processed.

The exradius of the annular tray 11 is less than gear radius to be processed.

The horizontal space of annular 11 center of circle of tray to 6 right side of briquetting is consistent with the annular radius of tray 11.

The utility model is implemented: as shown in Figure 1, dotted portion gear to be processed in figure, by gear set On locating shaft 10, gear lower end passes through annular tray 11 and holds, and then drives briquetting 6 mobile downwards by cylinder 5, briquetting 6 Gear is compressed, and the engaging tooth 71 on locating piece 7 is meshed with gear, to can guarantee that gear cannot circumferentially rotate, is increased Its strong processing stability, simultaneously because the exradius of annular tray 11 is less than gear radius, and annular 11 center of circle of tray is to pressing The horizontal space of 6 right side of block is consistent with the annular radius of tray 11, therefore gear outer ring stretches out annular tray 11 and briquetting is right End, can facilitate and finish to gear.
