A kind of cylindrical grinder with the two main shafts in both sides
The utility model relates to a kind of cylindrical grinder, particularly, relates to a kind of cylindrical grinder with the two main shafts in both sides.
Cylindrical grinder is the grinding machine that is used for grinding cylinder shape and conical external surface.Existing its main frame of peripheral milling wheeled litter by board, be arranged on grinding head on the machining spindle, fixedly the parts such as positioner and transmission dust exhaust apparatus of workpiece to be processed constitute.Cylindrical grinder is that the two top hearts with positioner are the center, is cutter with the emery wheel of grinding head, and cylindrical workpiece to be processed (steel part) is ground out the grinding machine of accurate concentricity.
In process of lapping, be divided into several operations such as preliminary grinding, correct grinding usually, to improve grinding precision.Common cylindrical grinder only comprises a grinding head, and for example preliminary grinding grinding head or correct grinding grinding head are carrying out between preliminary grinding and the precision grinding process; Need scrub the workpiece after the preliminary grinding; And change on the grinding machine of correct grinding and retighten, not only increase an operation and increased corresponding grinding machine, and complicated operation; Therefore the labor intensive material resources need to do to improve further.
The utility model content
The problem that the utility model will solve is: the problem that is directed against above-mentioned existence provides a kind of and can carry out the cylindrical grinder with the two main shafts in both sides preliminary grinding and correct grinding and that simplify working process simultaneously.
The technical scheme that the utility model adopted is: a kind of cylindrical grinder with the two main shafts in both sides is provided; Comprise that board reaches the fixedly work station of workpiece to be processed; Said work station is located on the said board; It is characterized in that: the both sides that on said board, are positioned at said work station also are respectively equipped with two machining spindles and two slide rails, and said two machining spindles are located at respectively on said two slide rails, and said slide rail guides two machining spindles on board, to carry out reciprocating action; Be respectively equipped with abrasive disk on said two machining spindles, said two abrasive disks are respectively correct grinding abrasive disk and preliminary grinding abrasive disk.
Further, said work station comprises a pair of locator, and said locator is fixed on workpiece to be processed between said two machining spindles, also comprises the fixed station that is arranged on the said board, and said locator is fixed on the said fixed station.Said locator is fixed on workpiece to be processed between two machining spindles, the side of convenient two abrasive disks processing workpiece to be processed.
Preferably, said two machining spindles are separately positioned on the front and rear edge place near said board, and making full use of the space on board top, thereby each parts of reasonable Arrangement conveniently carry out attrition process to workpiece to be processed.
Compared with prior art; The cylindrical grinder with the two main shafts in both sides that the utility model provides has correct grinding abrasive disk and preliminary grinding abrasive disk; Can carry out preliminary grinding to workpiece to be processed simultaneously and finish grind the attrition process of two operations, and need not to prepare separately separately preliminary grinding grinding machine and correct grinding grinding machine, simplify the operation of grinding; Improve production efficiency, thereby saved manpower and materials.
Description of drawings
Fig. 1 shows the structural representation of the cylindrical grinder with the two main shafts in both sides that provides among the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing:
Embodiment: as shown in Figure 1; Cylindrical grinder in the present embodiment is a kind of cylindrical grinder with the two main shafts in both sides that can carry out attrition process to the surface of workpiece to be processed, and it comprises a board 5, a work station, fixed station, two machining spindles 3 and corresponding slide rail 4.
Wherein, work station is used for fixing workpiece to be processed, and work station comprises a pair of locator 2, and locator 2 is fixed on the fixed station to be fixed.Locator 2 is fixed on workpiece to be processed between two machining spindles 3.Work station and fixed station roughly are located at the medium position of board 5 tops.
Two machining spindles 3 and two slide rails 4 are divided into two groups, are separately positioned on board 5 tops, and are positioned at the front and rear edge place near board 5 of the both sides of work station.Two machining spindles 3 are located at respectively on two slide rails 4, thereby make slide rail 4 guiding two machining spindles 3 on board 5, carry out reciprocating action.
Being respectively equipped with abrasive disk 1, two abrasive disk 1 on two machining spindles 3 is respectively correct grinding abrasive disk and preliminary grinding abrasive disk, thereby respectively workpiece to be processed is carried out preliminary grinding and correct grinding operation.
Add man-hour; Workpiece to be processed is fixed between two locators 2 of work station; Preliminary grinding abrasive disk and the correct grinding abrasive disk of controlling two machining spindles 3 then carry out attrition process to workpiece to be processed; And two abrasive disks 1 of two machining spindles 3 are through mobile on slide rail 4, thereby completion is to the workpiece to be processed attrition process.Make the utility model to carry out preliminary grinding to workpiece to be processed simultaneously like this and finish grind the attrition process of two operations; And need not separately workpiece to be processed to be changed to finish grinding grinding machine from the preliminary grinding grinding machine; Saved preliminary grinding and finish grinded the operation of scrubbing required between two operations, simplified the operation of grinding workpiece to be processed.
