Abstract
The utility model discloses a floating support combined device of an electromagnetic centerless fixture of an internal grinding machine. The device is used for grinding a bearing ring roller path. The device is characterized in that floating support supporting seats are connected to a supporting body; supporting heads are connected to the supporting seats; the supporting seats and the supporting heads are all in V shapes; and each floating support is the combination of double-floating supports, or a single-floating support; and each supporting seat is provided with two supporting heads. When floating support combined device is used, relative to the radial direction of a processed piece, the double-floating supports are installed at grinding positions, and the single-floating support is installed on the left lower position; and relative to the lateral direction of the processed piece, the single-floating support is arranged between the double-floating supports. Each V-shaped supporting seat of the floating support combined device is provided with two V-shaped supporting heads. When the floating support of the electromagnetic centerless fixture is used, the front support of the floating support is optimally designed into the double-floating support, and a rear support is designed into single-floating support so as to fully satisfy the technical requirement that the roundness of the bearing ring roller path of a locomotive is less than or equal to 0.005mm, and the bearing ring roller path has stable and reliable grinding quality.
Description
Technical field
The utility model relates to the jig technical field, is a kind of internal grinder electric magnetic no-core clamp floating support composite set that is used for the grinding of locomotive axle bearing ring raceway specifically.
Background technology
What the grinding of locomotive axle bearing ring was taked is the electric magnetic no-core clamp location; The mode that the tradition holding workpieces is taked is that former and later two supportings are single floating support, and like Fig. 7, Fig. 8, Fig. 9, shown in Figure 10, sequence number 1 is preceding supporting; Sequence number 2 is a workpiece; Sequence number 3 is a grinding machine head, and sequence number 4 is back supporting, and on the workpiece horizontal section two be bearing on the concentric circles.Because the particularity that the locomotive axle bearing ring is repaired; Quality when often causing grinding is unstable; This is to repair the phase because the external diameter of locomotive axle bearing ring to be processed all is to use to reach in one, and some corrosion vestiges are arranged, and can influence supporting beating in the course of the work; On the one hand can cause the offset of adjusting to change, can cause part defective on the lasso external diameter to rerun a movie on the crudy of interior circle on the other hand.
Summary of the invention
For overcoming the deficiency of prior art, the goal of the invention of the utility model is to provide a kind of internal grinder electric magnetic no-core clamp floating
Moving supporting composite set improves the former single floating support of electric magnetic no-core clamp, and the operation technique of the electric magnetic no-core clamp floating support after just improving simultaneously is optimized, and to realize quick location, avoids the defective of the work mounting s face machined surface of rerunning a movie.
For realizing above-mentioned purpose, the utility model comprises supporting mass, it is characterized in that: the supporting base of floating support is connected on the supporting mass through the axle of having strong market potential, and supporting head is connected on the supporting base through short pin shaft, and the structure of supporting base and supporting head is " V " font; Floating support is two floating support combinations, or single floating support form; Two supporting heads are installed on each supporting base; " V " font angle of supporting base and supporting head is between 120 °～160 °; Supporting base and supporting head are ± 5 ° around the axle of having strong market potential, the short pin shaft anglec of rotation respectively, and the centre of supporting head has the groove of rub when being used for holding workpieces heat radiation and eliminating foreign matter; During use, relatively the footpath of workpiece upwards, two floating supports are installed on the position of grinding, single floating support be installed in the lower left to; Workpiece is horizontal relatively, and the position that single floating support is installed is in the centre of two floating supports.
The preceding support design of the utility model holding workpieces becomes two floating supports, and single floating support design is adopted in supporting then, adds the containing angle of big bear to bearing-surface, to reduce the influence of work mounting s planar defect to crudy.
The utility model compared with prior art; Two " V " type supportings are installed on each after the improvement " V " type supporting base; The electric magnetic no-core clamp floating support in use, optimal design is that two floating supports are adopted in preceding supporting (being exactly the supporting near emery wheel), the form of the single floating support of back supporting (being exactly the supporting away from emery wheel) employing; Can fully satisfy the specification requirement of railway locomotive bearing ring raceway circularity≤0.005mm, bearing ring raceway grinding quality is reliable and stable.

The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; The supporting base 3 of floating support is connected on the supporting mass 1 through the axle 2 of having strong market potential, and supporting head 5 is connected on the supporting base 3 through short pin shaft 4, and supporting base 3 is " V " font with the structure of supporting head 5; The circular arc design is all taked in the bottom; In order to increase the wrapping angle that supporting is contained as much as possible, avoid of the influence of workpiece 6 external diameter defectives simultaneously to grinding quality, two supporting heads 5 are installed on each supporting base 3; " V " font angle of supporting base 3 and supporting head 5 is between 120 °～160 °; Be ± 5 ° around the axle 2 of having strong market potential, short pin shaft 4 anglecs of rotation in order to limit supporting base 3 respectively with supporting head 5 simultaneously, the space that supporting base 3 and supporting head 5 keep 1～2mm from the bottom of installed surface, supporting head 5 dwindles on the original shape size; The centre has the groove of wide 2mm, dark 2mm, heat radiation and eliminating foreign matter when being beneficial to the holding workpieces friction.Floating support can be for being two floating supports combinations, like Fig. 1, shown in Figure 2, or single floating support form, like Fig. 3, shown in Figure 4.
During use, relatively the footpath of workpiece 6 upwards, two floating supports are installed on the position of grinding, single floating support be installed in the lower left to; Workpiece is horizontal relatively, and the position that single floating support is installed is in the centre of two floating supports, like Fig. 5, shown in Figure 6.Sequence number 7 is an emery wheel.
