Abstract
The utility model discloses a grinding pressure adjusting device of a double-layer grinder which can save the cost and improve the processing quality. The grinding pressure adjusting device of the double-layer grinder comprises a lower millstone (6) driven by a lower millstone transmission system (3), as well as an upper millstone (7) and a secondary millstone (4) that are driven by an upper millstone transmission system (14). The grinding pressure adjusting device of the double-layer grinder is characterized in that a connector (8) is arranged on the upper millstone (7); a piston rod (13) on a hydraulic cylinder (10) is connected with the connector (8); an oil outlet tube (9) and an oil inlet tube (11) that are communicated with a piston cavity (12) are arranged on the hydraulic cylinder (10). The grinding pressure adjusting device of the double-layer grinder has simple structure; by increasing the working pressure for grinding, lighter grinding millstones can be adopted, so that the difference between the working pressure on the upper layer and the working pressure on the lower layer is reduced; therefore, the processing quality of the two layers is further approached; moreover, not only the processing quality is improved, but also the manufacture cost is saved.
Description
Technical field
The utility model relates to a kind of double-deck grinder, specifically a kind of grinding pressure adjusting device of double-deck grinder.
Background technology:
At present, double-deck grinder is to place two pairs of abrasive disks to process workpiece, though solved production efficiency problem, and can use less abrasive disk, provide but the grinding pressure of double-deck grinder is the gravity by upper millstone and subsidiary body, and existing pneumatic pressure regulating device can only reduce pressure, therefore, abrasive disk is done to such an extent that more thick and heavyly can guarantee that just enough grinding operating pressures are arranged, thereby the manufacturing cost of abrasive disk also can increase.
Summary of the invention
The purpose of this utility model provides a kind of grinding pressure adjusting device that can save cost, improve the double-deck grinder of crudy.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of grinding pressure adjusting device of double-deck grinder, it comprises lower millstone that is driven by the lower millstone transmission system and upper millstone, the secondary mill that is driven by the upper millstone transmission system, upper millstone is provided with connector, piston rod on the hydraulic cylinder is connected with connector, and hydraulic cylinder is provided with flowline, the oil inlet pipe that is communicated with plunger shaft.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, grind operating pressure by increasing, can adopt lighter abrasive disk, upper and lower two-layer operating pressure gap is dwindled, therefore, two-layer crudy is further approaching, has not only improved crudy, also saves manufacturing cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of grinding pressure adjusting device of double-deck grinder, it comprises lower millstone 6 that is driven by lower millstone transmission system 3 and upper millstone 7, the secondary mill 4 that is driven by upper millstone transmission system 14, upper millstone 7 is provided with connector 8, piston rod 13 on the hydraulic cylinder 10 is connected with connector 8, and hydraulic cylinder 10 is provided with flowline 9, the oil inlet pipe 11 that is communicated with plunger shaft 12.
During the utility model work, lower millstone transmission system 3 drives vertical shaft 2 rotations that are installed on the base 1 by flat key, and vertical shaft 2 drives lower millstone 6 rotations by flat key.4 on upper millstone 7 and secondary mill are connected drive by gear with upper millstone transmission system 14, and with identical rotating speed rotation, its direction of rotation is opposite with the direction of rotation of lower millstone 6.Workpiece 5 places between secondary mill 4 and the lower millstone 6 respectively and between lower millstone 6 and the upper millstone 7.When mill rotates, realize grinding and polishing processing to workpiece 5.
When grinding operating pressure when not enough, will feed the high-pressure and hydraulic oil by oil inlet pipes 11 in the plunger shaft 12 of hydraulic cylinder 10, and flowline 9 is connected oil return systems, can increase the grinding operating pressure, regulates the pressure of hydraulic oil, can realize grinding the step-less adjustment of operating pressure.The plunger shaft 12 of hydraulic cylinder 10 is fed high-pressure and hydraulic oil by flowline 9, and oil inlet pipe 11 is connected oil return system, can reduce the grinding operating pressure.
The install operation process of workpiece 5 is as follows: flowline 9 one ends feed high-pressure and hydraulic oil, oil inlet pipe 11 is connected oil return system, the piston rod 13 of hydraulic cylinder 10 drives connector 8 upper millstone 7 and lower millstone 6 is sling, operating personnel place workpiece 5 on the secondary mill 4, after installing, oil inlet pipe 11 feeds high-pressure and hydraulic oil, and flowline 9 is connected oil return system, puts down connector 8.Unclamp the connector between upper millstone 7, the lower millstone 6, flowline 9 one ends feed high-pressure and hydraulic oil once more, oil inlet pipe 11 is connected oil return system, the piston rod 13 of hydraulic cylinder 10 drives connector 8 upper millstone 7 is sling, and operating personnel place workpiece 5 on the lower millstone 6 of lower floor, after installing, oil inlet pipe 11 feeds high-pressure and hydraulic oil, and flowline 9 is connected oil return system, puts down connector 8, workpiece 5 installations.
Workpiece 5 machines the process and the similar process that workpiece 5 is installed that product is taken out in the back, just takes out the workpiece 5 on upper strata earlier, takes out the workpiece 5 of lower floor again.
