The vertical disc grinder comprises a grinder body, vertical spindles and a worktable; the vertical spindles are driven by a transmission, the first vertical spindle and the second vertical spindle which can be perpendicularly fed are parallelly mounted on the upper portion of the grinder body, a grinding wheel with rough end surfaces is arranged at the lower end of the first vertical spindle, and a grinding wheel with fine end surfaces is arranged at the lower end of the second vertical spindle; and the horizontal circular worktable driven by a transmission is mounted below the middle of the grinder body, the grinding wheel with the rough end surfaces and the grinding wheel with the fine end surfaces, the diameter of the grinding wheel with the rough end surfaces and the diameter of the grinding wheel with the fine end surfaces are not larger than the radius of the horizontal circular worktable, and the grinding wheel with the rough end surfaces and the grinding wheel with the fine end surfaces are positioned above one side of the horizontal circular worktable. Each workpiece only needs to be clamped and detached at one step to be roughly ground and finely ground. The vertical disc grinder and the machining method have the advantages that after each workpiece is clamped on the same grinder at one step, a rough grinding procedure and a fine grinding procedure can be completed, time elapsed for mounting and detaching the workpiece again is saved, fine grinding allowance can be small, and the production efficiency can be improved by 40%-60%.
Description
Technical field
The invention belongs to the machining tool field, particularly a kind of pair of bistrique vertical disc grinding machine and processing method thereof.
Background technology
The vertical disc grinding machine can be processed two parallel planes (being commonly called as face grinding) of all kinds of parts, can reach very high dimensional accuracy, the depth of parallelism and flatness requirement.Grinding machine mainly is comprised of bistrique and the large parts of workbench two, and bistrique is erect and is contained on lathe bed, and its upper end is by the rotation of driven by motor main shaft, and cup emery wheel is contained in the main shaft lower end; Circular table is positioned at the below of cup emery wheel, and level is arranged on lathe bed, and workpiece is fixed on workbench by fixture.Existing vertical disc grinding machine all only has a bistrique, can only fill a slice emery wheel.During grinding work piece, workbench is with certain speed around central rotation, and the operation handwheel drives main shaft gradually to bottom offset by leading screw, makes emery wheel contact workpiece start grinding, until reach the size needed.Because the surplus of grinding is larger, in order to raise the efficiency, adopt many disc grinders that this operation of face grinding is divided to corase grind and refined two operations more.During corase grind, grinding machine is installed the thicker emery wheel of granularity, grinds off most surplus of workpiece, during fine grinding, the thinner emery wheel of granularity is installed, and is ground to the size needed, and can reach high-precision dimensional requirement, morpheme public relations and surface roughness requirement.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of while and can carries out two bistrique vertical disc grinding machines and the processing method thereof of workpiece corase grind and fine grinding.
Solve the problems of the technologies described above, technical scheme of the present invention is: a kind of pair of bistrique vertical disc grinding machine, the vertical spindle and the workbench that comprise lathe bed, actuator drives, 1# vertical spindle and the 2# vertical spindle of energy vertical feed installed on lathe bed top side by side, the butt end facet wheel is equipped with in 1# vertical spindle lower end, and the taper end facet wheel is equipped with in 2# vertical spindle lower end; The horizontal circular table of actuator drives is installed in the below of lathe bed middle part, butt end facet wheel and taper end facet wheel, the diameter of described butt end facet wheel and taper end facet wheel is not more than the radius of the circular work of level, and butt end facet wheel and taper end facet wheel are positioned at the top of horizontal circular table one side.Fixture or horizontal circular table that described horizontal circular table is provided with holding workpiece are the circular magnetic working table of level.
Adopt the processing method of two bistrique vertical disc grinding machines: disposable by workpiece put into be fixed in the fixture hole on circular table or the circular magnetic working table of the level that is positioned on, open successively cooling, workbench motor, coarse plain emery wheel spindle motor, the 1# vertical spindle that the rotation wheel feed is equipped with the butt end facet wheel starts grinding, after workpiece is worked into the corase grind size, 1# vertical spindle withdrawing; The 2# vertical spindle that the rotation wheel feed is equipped with the taper end facet wheel carries out fine grinding, after reaching size, unloads workpiece; Workpiece is as long as clamping and dismounting respectively once just can complete corase grind and fine grinding.
The invention has the beneficial effects as follows: on same equipment once after clamping workpiece, complete the processing of roughly grinding and refining two operations, save once mounting and the time of unloading workpiece, can stay littlely by the surplus of fine grinding, can put forward 40% ~ 60% production efficiency simultaneously.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is horizontal circular table schematic diagram.
The specific embodiment
Embodiment 1As shown in Fig. 1,2: a kind of pair of bistrique vertical disc grinding machine, the vertical spindle and the workbench that comprise lathe bed, actuator drives, 1# vertical spindle 1 and the 2# vertical spindle 2 of energy vertical feed installed on lathe bed 3 tops side by side, butt end facet wheel 5 is equipped with in 1# vertical spindle 1 lower end, and taper end facet wheel 4 is equipped with in 2# vertical spindle 2 lower ends; The horizontal circular table 8 of actuator drives is installed in the below of lathe bed 3 middle parts, butt end facet wheel 5 and taper end facet wheel 4, the diameter of butt end facet wheel 5 and taper end facet wheel 4 is not more than the radius of horizontal circular table 8, and butt end facet wheel 5 and taper end facet wheel 4 are positioned at the top of horizontal circular table 8 one sides.Fixture 7 or horizontal circular table 8 that described horizontal circular table 8 is provided with holding workpiece 6 are the circular magnetic working table of level.
Embodiment 2As shown in Fig. 1,2: the processing method that adopts pair bistrique vertical disc grinding machine as described in embodiment 1: disposable by workpiece put into be fixed in fixture 7 holes on circular table 8 or the circular magnetic working table of the level that is positioned on, open successively cooling, workbench motor, coarse plain emery wheel spindle motor, rotate the 1# vertical spindle 1 beginning grinding that wheel feed is equipped with butt end facet wheel 5, after workpiece is worked into the corase grind size, 1# vertical spindle 1 withdrawing; The 2# vertical spindle 2 that the rotation wheel feed is equipped with taper end facet wheel 4 carries out fine grinding, after reaching size, unloads workpiece; Workpiece is as long as clamping and dismounting respectively once just can complete corase grind and fine grinding.
The end face that the vertical disc grinding machine that the model of now take is 2M7431 (310 millimeters of workbench diameters, 125 millimeters of grinding wheel diameters), the processing work of take are the SPKN1504EDR carbide chip is the two advantages of bistrique vertical disc grinding machine on production efficiency of example explanation.Workpiece blank thickness is 5.1 millimeters, requires to be worked into 4.76 ± 0.025 millimeters, surface roughness Ra 0.4.But this equipment once 66 SPKN1504EDR blades of clamping carries out grinding.
