Special purpose grinder at the bottom of workpiece slot
The utility model relates to a kind of special processing equipment of field of machining, for the bottom land grinding of workpiece.
Existing work pieces process process characteristic is shown in Fig. 1, and in processing front view, 43 groove bottom and large plane are all a plane, can not process simultaneously.The process route adopted is the large plane that first wire rod quality processes 232 widths, and then uses cylindrical milling cutter milling 43 groove bottom and two sides.Cause 43 groove bottom and 232 large planes, not disposable processing, connects cutter phenomenon, and flatness is deteriorated, and does not reach drawing requirement.
Adopt hand electric polisher, grinding is carried out to groove bottom.First install, rough grinding wheel sheet, roughly grinds; Then change meticulous grinding wheel and carry out polished finiss.Adopt this kind of method, its machining accuracy and efficiency follow operator's qualification relevant, and the working (machining) efficiency of practician is higher, and yield rate is also higher; On the contrary, unskilled person, then completely contrary, sometimes cause batch to scrap or soldering.Another one shortcoming is, everyone will hold two sanding machines simultaneously, one for roughing, one for fine finishining.
Utility model content
In order to eliminate the overproof problem of flatness caused because of a plane point secondary operations, the utility model discloses a kind of workpiece slot bottom surface special purpose grinder, the utility model not only solves the plane unevenness problem that this workpiece 43 groove bottom and 232 large planes produce because of secondary operations, but also can solve the flat surface grinding problem of similar workpiece.
The technical solution adopted in the utility model is as follows:
Special purpose grinder at the bottom of workpiece slot, comprise the support of a L-type, at the horizontal plane of support, a location of workpiece adjusting device is installed, the vertical plane of support is installed emery wheel drive and adjusting device, described emery wheel drives and adjusting device comprises motor, described motor, grinding wheel spindle, gripper shoe, adjustment handwheel and leading screw, described motor is arranged on above gripper shoe, is connected with the belt pulley on grinding wheel spindle by belt transmission; Grinding wheel spindle installs emery wheel, and gripper shoe is articulated with on support vertical plate; Described adjustment handwheel drives leading screw to rotate, and leading screw one end is hinged on support vertical plate, and the nut of the leading screw other end and gripper shoe screws.Rotating handwheel makes gripper shoe be that circular motion is done in the center of circle with hinged, thus the spatial altitude of installation emery wheel is on the supporting plate changed, and for feed and push broach, completes grinding task.
Described location of workpiece adjusting device comprises longitudinal rail pair, cross slide way pair and skewback clamp system, described longitudinal rail pair is arranged on base-plate, longitudinal rail pair connects slide plate, described slide plate is installed cross slide way pair, the slide plate of described cross slide way pair is provided with workpiece height adjusting device.
Described workpiece height adjusting device comprises two skewbacks, the work piece holder matched with it is provided with at the top of two skewbacks, described skewback is arranged in skewback chute, described skewback chute is arranged on the slide plate of cross slide way pair, and two of skewback chute axis are parallel to each other, be provided with screw in the middle of each skewback, wherein one piece is left hand thread, another block is right-handed thread, and described left hand thread, right-handed thread coordinate with left-right turning screw rod respectively.
Described skewback and the mating surface of work piece holder are height is in vertical direction change, adjust the spacing of two skewbacks, be coupled with the fixture above with skewback, rotational lead screw, skewback goes in the same direction or opposing and go in chute, clamp body is moved up and down, and clamp body drives workpiece to move up and down, by being welded on the clamp of cross rail slide plate both sides by the Workpiece clamping on clamp body.
The two ends assembled shaft bearing of described grinding wheel spindle, is arranged on below gripper shoe; Described gripper shoe is for carrying motor and grinding wheel spindle
The beneficial effects of the utility model are as follows:
This apparatus structure has three-dimensional adjustment principle, and can realize plane positioning and the clamping of workpiece, cutter can realize Z-direction feed, possesses the essential characteristic of grinding machine.The clamping of workpiece, have employed the cooperation of skewback and left-right turning screw rod, completes workpiece lifting from clamping.Practical simple, cost of manufacture is lower, has very high use value and science.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
This part-structure of holder part is " L " type support 1, and its function is, the vertical plane of " L " type support 1 is used for propping sand wheel drive and adjustment member 2, and horizontal plane is mainly used in support fixture and workpiece portion.This part will have good rigidly, firmly, is equivalent to the lathe bed of lathe.
Emery wheel drives and adjustment member: the function of this part is, completes the High Rotation Speed of emery wheel; Emery wheel is made to do moving of feed and withdrawing along Z axis.Comprise motor 3, grinding wheel spindle 6, gripper shoe 5, adjustment handwheel 4 and leading screw 8 etc.Motor is the power resources that emery wheel drives, and is arranged on above gripper shoe, is connected by belt transmission with the belt pulley on grinding wheel spindle; Emery wheel is installed in grinding wheel spindle middle part, and axle two ends assembled shaft bearing, is arranged on below gripper shoe 5; Gripper shoe 5, for carrying motor and grinding wheel spindle, is connected with set lagging by hinged; Adjustment handwheel can drive leading screw to rotate, leading screw one end is hinged on set lagging, the nut of the leading screw other end and gripper shoe screws, rotating handwheel can make gripper shoe be that circular motion is done in the center of circle with hinged, thus the spatial altitude of installation emery wheel is on the supporting plate changed, for feed and push broach, complete grinding task.
Fixture and workpiece 14: this partial function is, the plan-position of adjustment workpiece; Locating clip clamping of workpieces, makes workpiece occupy tram when grinding; Complete feed and withdrawing.
This part is divided into: the parts such as longitudinal rail pair 9, cross slide way pair 7, skewback clamp system, pressing plate 10, left-right turning screw rod and handwheel.Longitudinal rail pair 9 is assemblied in respectively on base-plate and longitudinal rail secondary slide 13 by a pair semi-circular spherical guide pair and is formed, cross slide way is secondary, is arranged on longitudinal rail secondary slide 13 in the same way, skewback clamp system, on cross slide way secondary slide 12, have the skewback chute that two axis are parallel to each other, a skewback 11 is provided with in each skewback chute, be screw in the middle of each skewback 11, wherein one piece is left hand thread, another block is right-handed thread, be connected with left-right turning screw rod 8 respectively, adjust the spacing of two skewbacks, can be coupled with the clamp body above with skewback, rotational lead screw, skewback can go in the same direction or opposing and go in chute, clamp body is impelled to move up and down, clamp body drives workpiece to move up and down, by being welded on the clamp 10 of cross rail slide plate both sides by the Workpiece clamping on clamp body.Can be realized by the function of above mechanism, workpiece slot bottom surface, the grinding of side, guarantees required precision.In addition, the guideway of this device has adjustable limiting, can in adjusting range optional position by Workpiece fixing.
