Abstract
The utility model relates to a sine indexing plate for a grinding wheel arc angle R-correcting fixture. The sine indexing plate comprises a base (1), an indexing plate body (2), an indexing column (4) and a cushion block. Both sides of the center of the indexing plate body (2) are provided with an input shaft (3) and an output shaft (9) which are coaxially arranged; the tail end of the input shaft (3) is fixedly connected with a rocker handle (6); the side surface of the indexing plate body (2) is provided with scale marks (7); a pointer (8) is arranged above the top of the indexing plate body (2); the indexing column (4) is arranged on the edge of the indexing plate body (2) and close the side where the input shaft (3) is arranged; the cushion block (5) is fixed onto the base (1). The sine indexing plate for the grinding wheel arc angle R-correcting fixture has the advantages that operators do not need to perform reading all the time; meanwhile, when the indexing column is pressed onto the cushion block, the indexing plate body automatically stops rotation, low requirements on the technological level of the operators, small positioning errors and a simple structure can be obtained.
Description
Technical field
The utility model relates to grinding wheel arc angle trimming device, particularly grinding wheel arc angle and repaiies the sinusoidal index dial of R fixture.
Background technology
Dresser is that grinder wheel is carried out to the aid that size, shape, geometric angle etc. are repaired.In order to meet the needs of production, trimming wheel often runs in actual production.Be mainly according to institute's processing work geometry and surface accuracy requirement etc., after emery wheel is repaired, again workpiece carried out to reconditioning, reach and guarantee mill cut part quality requirement, so the finishing of emery wheel plays an important role to the precision of grinding.Traditional crushing is to carry out hand finish by grinding wheel dressing pen, or adopts moulding trimmer (as roller) to repair.But the emery wheel after these two kinds of method finishings all can produce circular shape error, the form accuracy of workpiece after impact processing.The reason that affects crushing precision has two aspects: the one, and the precision of trimmer itself; The 2nd, misoperation.
Generally, the arc at emery wheel edge is fixing, the corresponding central angle of arc is fixed value, after abrasion of grinding wheel, arc changes, now need to repair by trimming device, traditional dresser is provided with index dial, on index dial, be provided with graduation mark and pointer, movement by graduation mark with respect to pointer, determine the anglec of rotation of trimming device, when operation, operating personnel rotate the handle being connected with index dial on one side, the anglec of rotation of observing index dial on one side, operating personnel are difficult to adjust to angle just, technical merit to operating personnel is had relatively high expectations, and inevitably there is error, cause arc finishing accuracy lower.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of easy to operate, registration and grinding wheel arc angle simple in structure to repair the sinusoidal index dial of R fixture.
The purpose of this utility model is achieved through the following technical solutions: grinding wheel arc angle is repaiied the sinusoidal index dial of R fixture, it comprises base, index dial body, dividing column and cushion block, index dial body is vertically arranged on the top of base, the both sides of index dial body center are fixed with respectively power shaft and the output shaft of coaxial line, input the tip of the axis is fixedly connected with rocker lever, on the side of index dial body, be provided with graduation mark, the over top of index dial body is also provided with pointer, dividing column is arranged on the edge of index dial body, and near power shaft one side; Described cushion block is fixed on base.
Described dividing column has three, and three dividing columns are on 90 ° of same circumference that are distributed in index dial body.
Described cushion block is less than the height of dividing column to the beeline of index dial body.
The utlity model has following advantage: by cushion block, coordinate with dividing column, the anglec of rotation of index dial body is converted to the height of cushion block, operating personnel can be according to arc angle shape, through simple computation, obtain the height of cushion block, cushion block is arranged on base, the rotation of index dial body, when dividing column is pressed on cushion block, the angle of index dial body rotation is required arc angle, in whole process, operating personnel do not need omnidistance reading, and dividing column is pressed on cushion block, index dial body stops the rotation automatically, to operating personnel's technical merit, require lower, and the error of location is little, its structure is also very simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left TV structure schematic diagram of Fig. 1;
Fig. 3 is the structural representation that index dial rotates to an angle;
In figure: 1-base, 2-index dial body, 3-power shaft, 4-dividing column, 5-cushion block, 6-rocker lever, 7-graduation mark, 8-pointer, 9-output shaft.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As depicted in figs. 1 and 2, grinding wheel arc angle is repaiied the sinusoidal index dial of R fixture, it comprises base 1, index dial body 2, dividing column 4 and cushion block 5, index dial body 2 is vertically arranged on the top of base 1, the both sides of index dial body 2 centers are fixed with respectively power shaft 3 and the output shaft 9 of coaxial line, the end of power shaft 3 is fixedly connected with rocker lever 6, on the side of index dial body 2, be provided with graduation mark 7, the over top of index dial body 2 is also provided with pointer 8, dividing column 4 is arranged on the edge of index dial body 2, and near power shaft 3 one sides; Described cushion block 5 is fixed on base 1; Described cushion block 5 is less than the height of dividing column 4 to the beeline of index dial body 2.
Further, described dividing column 4 has three, and three dividing columns 4 are on 90 ° of same circumference that are distributed in index dial body 2.
Operation principle of the present utility model is: as shown in Figure 3, the central shaft of index dial body 2 is assumed to be H to the upper surface of base 1, the axis of dividing column 4 is assumed to be R to the axial line distance of index dial body 2, the radius of dividing column 4 is r, the anglec of rotation of index dial body 2 is α, the height of cushion block 5 is h, from geometrical relationship, H=h+r+R*sin α, wherein, H, r and R are fixed value, so h=H-r-R*sin α, can find out, h changes along with the variation of α, that is to say as long as the anglec of rotation of index dial body 2 is definite value, the height of cushion block 5 is definite value, the anglec of rotation of index dial body 2 is converted to the height of cushion block.
The course of work of the present utility model is as follows: when pointer 8 is during over against 0 of graduation mark 7, in three dividing columns 4, there are two both sides in index dial body 2, and in same level, another one dividing column 4 and graduation mark 70 over against, grinding wheel arc angle is α, by above-mentioned computing formula, calculate the height h of cushion block 5, to highly be fixedly mounted on base 1 for the cushion block 5 of h, after installation, by rotating rocker handle 6, drive index dial body 2 to rotate, in this process, do not need the continuous reading of operating personnel, when dividing column 4 is pressed on cushion block 5 upper surfaces, index dial body 2 rotates and stops.
