Abstract
The invention provides a dividing fixture for the 45-DEG positioning of a valve core, which can ensure that the four faces of a square column form a 45-DEG included angle with the plane of a valve plate and has convenience for use and simple structure. In the dividing fixture for the 45-DEG positioning of a valve core, the valve core comprises a valve plate and two core shafts located on both sides of the valve plate. The dividing fixture for the 45-DEG positioning of a valve core comprises a tip abutted against the central part of one end face of one core shaft and a self-centering chuck used for clamping the other core shaft, wherein the self-centering chuck is connected with a rotary dividing device for driving the self-centering chuck to rotate around the axis of the core shaft, and the minimum division value of the rotary dividing device is 90 DEG; and one 45-DEG oblique surface is arranged on one positioning frame, and an upper bulge and a lower bugle used for being in contact with the valve plate so that the valve plate is parallel to the oblique surface are arranged on the oblique surface.
Description
Technical field
Present technique relates to the anchor clamps that spool carried out 45 ° of location and calibration.
Background technology
Existing spool comprises valve plate and is positioned at two mandrels of valve plate both sides that needing to process the cross section at a mandrel is foursquare square column.Four faces of this square column will with the plane at valve plate place angle at 45 °.In order to process square column, need to position anchor clamps to spool, and need calibration.
Summary of the invention
The purpose of present technique provides and a kind of square column is added man-hour, can guarantee square column four faces will with the plane at valve plate place angle at 45 °, 45 ° of location indexing fixtures of spool easy to use, simple in structure.
45 ° of location indexing fixtures of this spool, described spool comprises valve plate and is positioned at two mandrels of valve plate both sides, 45 ° of location indexing fixtures of spool comprise top, the self-centering chuck that be used for to clamp another mandrel be used to an end face central part that withstands on a mandrel, self-centering chuck links to each other around the circular index device that the mandrel axis rotates with the drive self-centering chuck, and the minimum division value of circular index device is 90 °; Be provided with 45 ° of inclined-planes on the locating rack, be provided with on this inclined-plane for contacting with valve plate so that up and down two projections that valve plate parallels with the inclined-plane.
The beneficial effect of present technique: during use, two projections of locating rack are contacted with a side of valve plate, so that plane, valve plate place is the inclined-plane horizontal by 45 °, then clamp mandrel by self-centering chuck, get final product a face of milling square column this moment by the milling cutter that moves along horizontal plane.Behind face of milling, after 90 ° of existing circular index device drive chuck rotations, get final product another face of milling square column.Like this, the square column that processes just can satisfy the plane angle at 45 ° at four faces and valve plate place.
The circular index device belongs to prior art.Workpiece is in clamped one time. and whenever process after the surface, turn over certain angle by moving part on the anchor clamps together with workpiece, to change the position of finished surface. the device of realizing above-mentioned calibration requirement is called the circular index device.
45 ° of location indexing fixtures of above-mentioned spool, self-centering chuck is scroll chuck.Self-centering chuck is prior art, but namely the claw radial concentric moves and makes the self centering chuck of workpiece.
Description of drawings
Fig. 1 is the front view of 45 ° of location indexing fixtures of spool.
Fig. 2 is the right view of 45 ° of location indexing fixtures of spool.
Fig. 3 is the X-X cutaway view among Fig. 1.
The specific embodiment
Referring to 45 ° of location indexing fixtures of the spool shown in Fig. 1-3, comprise the three-jaw self-centering chuck 3 be used to top 2, the right side mandrel 13 that is used for clamping spool 1 of the left side central part of the left side mandrel 12 that withstands on spool 1, self-centering chuck with drive three-jaw self-centering chuck and link to each other around the circular index device 4 that the mandrel axis rotates, top 2, three-jaw self-centering chuck 3, circular index device 4 all are arranged on the frame 5.
Be provided with the bottom surface 62 of 45 ° of inclined-planes 61 and level on the locating rack 6, be provided with on the inclined-plane for contacting with the valve plate 11 of spool so that up and down two projections 63 that valve plate parallels with the inclined-plane.
Claims (2)
1. 45 ° of location indexing fixtures of spool, described spool comprises valve plate and is positioned at two mandrels of valve plate both sides, it is characterized in that: 45 ° of location indexing fixtures of spool comprise top, the self-centering chuck that be used for to clamp another mandrel be used to an end face central part that withstands on a mandrel, self-centering chuck links to each other around the circular index device that the mandrel axis rotates with the drive self-centering chuck, and the minimum division value of circular index device is 90 °; Be provided with 45 ° of inclined-planes on the locating rack, be provided with on this inclined-plane for contacting with valve plate so that up and down two projections that valve plate parallels with the inclined-plane.
2. 45 ° of location indexing fixtures of spool as claimed in claim 1, it is characterized in that: self-centering chuck is scroll chuck.
