Abstract
The utility model discloses a pressurizing device of a double-layer grinder, which can guarantee same working pressure of two pairs of grinding millstones. The pressurizing 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 (9). The pressurizing device of the double-layer grinder is characterized in that a vertical shaft is a step shaft (2) connected with a base (1); the lower millstone (6) is mounted on a shaft shoulder (10) of the step shaft (2); and a hydraulic cylinder (12) connected with a connecting bearing (11) is arranged below the secondary millstone (4). The pressurizing device of the double-layer grinder has simple structure, same working pressure of the two pairs of grinding millstones and same workpiece processing conditions, and guarantees product quality. Meanwhile, as the lower millstone and the vertical shaft are connected by a spline, workpieces in the lower layer are very convenient to mount and take out.
Description
Technical field
The utility model relates to a kind of face lapping mill, specifically a kind of double-deck grinder pressing device.
Background technology
At present, as the patent No. is 200920065138.4, the applying date is on April 23rd, 2009, denomination of invention is that the abrasive disk of face lapping mill discloses a kind of two pairs of abrasive disk structures, it adopts two pairs of abrasive disks that workpiece is processed, though solved production efficiency problem, and can use less abrasive disk, but because vertical shaft is not a multidiameter, its lower millstone is to be connected by flat key to realize transmission with vertical shaft, lower millstone, upper millstone acts directly on the secondary mill, secondary mill, workpiece pressure in the lower millstone is just greater than lower millstone, workpiece pressure in the upper millstone, and product quality is directly related with grinding pressure, therefore causes the product quality of grinding in two pairs of abrasive disks there are differences.Simultaneously, when the workpiece of installing and taking out in lower floor's grinding mechanism, owing to need the lifting lower millstone, the folding dress is not very convenient.
Summary of the invention
The purpose of this utility model provides two pairs of double-deck grinder pressing devices that the abrasive disk operating pressure is identical of a kind of assurance.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of double-deck grinder pressing device, it comprises the lower millstone that is installed on the vertical shaft and is driven by the lower millstone transmission system, upper millstone, secondary mill by the drive of upper millstone transmission system, described vertical shaft is the step axle that is connected with base, and lower millstone is installed on the shaft shoulder of step axle; Secondary mill has the hydraulic cylinder that is connected with connection bearing.
Step axle one end described in the utility model is provided with spline tooth, and lower millstone is provided with the keyway corresponding with spline tooth.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, the operating pressure of two pairs of abrasive disks is identical, and the workpiece processing conditions is identical, and product quality is guaranteed, simultaneously, owing to is connected with spline between lower millstone and the vertical shaft, therefore, installing and very convenient during taking-up lower floor processing work.
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 double-deck grinder pressing device, it comprises the lower millstone 6 that is installed on the vertical shaft and is driven by lower millstone transmission system 3, upper millstone 7, secondary mill 4 by 9 drives of upper millstone transmission system, described vertical shaft is the step axle 2 that is connected with base 1, and lower millstone 6 is installed on the shaft shoulder 10 of step axle 2; Secondary mill 4 has the hydraulic cylinder 12 that is connected with connection bearing 11.
Step axle 2 one ends described in the utility model are provided with spline tooth, and lower millstone 6 is provided with the keyway corresponding with spline tooth.
During the utility model work, lower millstone transmission system 3 drives step axle 2 rotations that are installed on the base 1 by flat key, and step axle 2 drives lower millstone 6 rotations by spline.4 on upper millstone 7 and secondary mill are connected drive by gear with upper millstone transmission system 9, and with identical rotating speed rotation, its direction of rotation is opposite with the direction of rotation of lower millstone 6.Workpiece 5 places respectively between secondary mill 4, lower millstone 6 and lower millstone 6, the upper millstone 7.When mill rotates, realize grinding and polishing processing to workpiece 5.
The grinding pressure of the upper strata grinding mechanism then gravity of upper millstone 7 and subsidiary body provides, and the grinding pressure of lower floor's grinding mechanism is then provided by hydraulic cylinder 12.Because the pressure of hydraulic cylinder 12 can be regulated, and can guarantee that two-layer grinding pressure is identical, thereby guarantee the crudy of workpiece 5.
The install operation process of workpiece 5 is as follows: pneumatic system is sling upper millstone 7, lower millstone 6 by pressure regulation and elevator system 8, and workpiece 5 is placed on the secondary mill 4, puts down pressure regulation and elevator system 8 after installing; Unclamp the connector between upper millstone 7, the lower millstone 6, start elevator system 8 once more, upper millstone 7 is sling, and workpiece 5 is placed on the lower millstone 6, puts down elevator system 8 after installing, and can regulate the pressure of 4 pairs of workpiece 5 of secondary mill by hydraulic cylinder 12.
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.
Claims (2)
1. double-deck grinder pressing device, it comprises the lower millstone (6) that is installed on the vertical shaft and is driven by lower millstone transmission system (3), upper millstone (7), secondary mill (4) by upper millstone transmission system (9) drive, it is characterized in that the step axle (2) of described vertical shaft for being connected with base (1), lower millstone (6) is installed on the shaft shoulder (10) of step axle (2); Secondary mill (4) has the hydraulic cylinder (12) that is connected with connection bearing (11).
2. double-deck grinder pressing device according to claim 1 is characterized in that described step axle (2) one ends are provided with spline tooth, and lower millstone (6) is provided with the keyway corresponding with spline tooth.
