Background technology:
When the machined of milling-boring machine accessories mill-head is done, because there is deviation in the rotation scale on milling head main shaft place body of milling head and the milling head base when processing and assembling scraping, when general assembly is debugged, can not accurately determine part zero graduation position in rotating 360 °, add the work precision thereby influence end facing machine.Determined in the past that method was that the dial gauge contact is pressed onto on the body of milling head main shaft end face, and drove milling head by the lathe main frame and move horizontally that adjust the anglec of rotation of body of milling head on the milling head base, the registration that makes dial gauge all was zero, determines the zero graduation position.This measurement determines that problem that method exists is that the minimum range of actual measurement may be near vertical range, rather than theoretical minimum range, actual range and theoretical have deviation, when being reflected at milling head Rotate 180 ° work, two scale milling head spindle axis just can not coplanar, there is the parallel difference of spindle axis, adds the work precision thereby influence end facing machine.
The utility model content:
Thereby technical problem to be solved in the utility model is to overcome actual the recording apart from having deviation to influence end facing machine with theoretical that exists in the background technology to add the work precision problem, and provide a kind of milling head accurately to determine zero graduation table bar instrument, this milling head determines that accurately zero graduation table bar instrument can make things convenient for milling head accurately to determine the zero graduation position, and precision is accurate when guaranteeing that end facing machine adds work.
The invention for solving the technical problem can reach by following technical solution: this milling head determines that accurately zero graduation table bar instrument comprises fixed bar, fixed bar one end is fixed in the mandrel, the other end is with dop, tie down screw penetrates in the hole of dop, the transverse end that penetrates L shaped table bar in the radial hole of tie down screw one end of cover is housed, there is the grooved bore parallel with transverse end the termination of vertical end of table bar, and there is screw hole grooved bore opening both sides, and the tie down screw other end is equipped with handle; The packing ring of two matched in clearance is housed between handle and dop, dial gauge is housed in the grooved bore.
The packing ring of described handle end is a copper sheet.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: this milling head is accurately determined zero graduation table bar instrument owing to adopt said structure, utilize the equidistant vertical principle in axle center and plane, to show bar installs on the milling head main shaft, table bar wheel measuring has been adjusted vertical four point value of parallel flat board with the milling head main frame, adjust body of milling head, determine that vertical four point value equate and body of milling head is vertically dull and stereotyped, thereby accurately determine the zero graduation position.Make things convenient for milling head accurately to determine the zero graduation position, precision is accurate when guaranteeing that end facing machine adds work.
