The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the utility model provides a kind of grinding square cross fixture, it comprises the workbench 2 that upper surface is vertical with grinding-wheel grinder bevel, it also comprises and being fixed on workbench 2 and perpendicular on the table top of workbench 2 and four pillars 1 of rectangular arrangement, on two adjacent pillars 1, common cover has a upper supporting plate 3 and a lower carrier plate 4, on other two adjacent pillars 1, also common cover has a upper supporting plate 3 and a lower carrier plate 4, four described pillars 1 to be provided with the device that regulates upper supporting plate 3 and lower carrier plate 4 upper-lower positions; It also comprises that two upper supporting plate 3 lower surfaces of connection are for pushing down the top board 5 of square cross 9 tops, connect two lower carrier plate 4 upper surfaces for padding the lower platen 6 below square cross 9 datum levels, upper supporting plate 3 can free adjustment be fixed on pillar 1 with lower carrier plate 4, be convenient to regulating reference surface parallel with work top, because work top is mutually vertical with the grinding face of emery wheel 8, guaranteed the crudy of grinding face simultaneously.
As preferably, described top board 5 and the width of lower platen 6 are less than the width of square cross 9, and emery wheel 8 can not encountered top board 5 and lower platen 6 like this, has guaranteed that emery wheel 8 can be worked into square cross 9 yet.
As preferably, one end that described lower platen 6 is in grinding entrance protrudes from corresponding lower carrier plate 4 away from one end of emery wheel 8, is convenient to like this, in lower platen 6 both sides, conveying mechanism is set, and square cross 9 is sent between emery wheel 8 and is processed.
As preferably, described can free adjustment upper supporting plate 3 and the device of lower carrier plate 4 upper-lower positions refer to that described pillar 1 is provided with external screw thread, described upper supporting plate 3 and lower carrier plate 4 can slide up and down at pillar 1, at every upper supporting plate 3, be equipped with a pair of nut 7 for regulating and locking with lower carrier plate 4 and the top and bottom that contact on pillar 1, with nut, regulate the position of top board 5 and lower platen 6, make the datum level of square cross 9 be parallel to work top, easy to adjust, quick.
As preferably, the one end away from upper supporting plate 3 or lower carrier plate 4 on described nut 7 is provided with locking nut, and locking nut is the position of upper supporting plate 3 and lower carrier plate 4 fixedly.
As preferably, it also comprises and is located at two baffle plates that are distributed in square cross 9 both sides between emery wheel 8 and grinding entrance, and the width of described baffle plate is more than or equal to the width of square cross 9, play the guiding role, and square cross 9 can accurately be entered between emery wheel 8.
As preferably, described being greater than refers to distance between baffle plate than the width of square cross 9 many 0.1 millimeter～0.5 millimeter, is conducive to square cross 9 and enters between emery wheel 8, can not normally not enter between emery wheel 8 because the distance between baffle plate is too large or too little.
Specifically, described upper supporting plate 3 and lower carrier plate 4 are arranged on pillar 1, first upper supporting plate 3 is maintained static, then mobile lower carrier plate 4 makes the lower surface of lower carrier plate 4 parallel with work top, during adjusting, need only the perpendicularity that regulates lower carrier plate 4 and pillar 1 with angle square, after regulating, the height level of two upper supporting plates 3, the height level of two lower carrier plates 4, with the fixing lower carrier plate 4 of nut, with the top board 5 on upper supporting plate 3, be pressed in the upper surface of square cross 9, the distance of guaranteeing top board 5 and lower platen 6 is the thickness of square cross 9, make the square cross 9 can be from wherein passing through, be unlikely to again too pine.Because pillar 1 is vertical with work top, lower carrier plate 4 is parallel with work top, and lower platen 6 lies on lower carrier plate 4, square cross 9 is placed on lower platen 6, so the datum level of square cross 9 is parallel with work top, because work top is mutually vertical with the grinding face of emery wheel 8, guaranteed the crudy of grinding simultaneously.
In addition, at lower platen 6, near one end of square cross 9 entrances, be provided with conveying mechanism, its conveying mechanism is the swiveling wheel 10 that is located at lower platen 6 both sides, between emery wheel 8 and rotation human relations 10, be provided with the baffle plate for playing the guiding role, the square cross 9 that rotarily drives by swiveling wheel 10 moves forward, and a plurality of square cross 9 is near arrangement, only has promotion square cross 9 below, just can promote square cross 9 above, thereby realize the processing of square cross 9 in batches.
With regard to the utility model preferred embodiment, be described above, but can not be interpreted as it is limitations on claims.This practicality is carried out and is not only confined to above embodiment, and its concrete structure allows to change, and all various variations of doing in the protection domain of the utility model demand for independence are all in protection domain of the present utility model.
