Description
Technical field
The present invention relates to a kind of surveying instrument, specifically a kind of surveying instrument that is used for the ball-cage constant velocity universal coupling channel dimensions.
Background technology
In mechanical industry, the application of ball-cage constant velocity universal coupling is very general.When the parallel axes of axle with axle, flange and flange, or axle with spool, during the axes intersect of flange and flange, best connected mode is exactly a ball-cage constant velocity universal coupling.
All the time, in design, the manufacturing and the check of ball-cage constant velocity universal coupling, the size method of rationally checking out accurately raceway groove is the difficult point in the check.Whether the parts eccentric throw of producing meets drawing requirement, and whether raceway groove bottom of trench size is accurate, is directly connected to the bearing torque performance of product and the dirigibility of shaft coupling rotation.The steel ball slide calliper rule are adopted in the detection of raceway groove bottom of trench size in the past more, and the steel ball slide calliper rule are the repacking of vernier caliper just, with the measuring claw place of the vernier caliper steel ball of burn-oning, just so-called steel ball slide calliper rule.In general; The precision of vernier caliper is also with regard to 0.1 millimeter, 0.05 millimeter and 0.02 millimeter three kinds, and is so the precision of steel ball slide calliper rule can be not high yet, poorer through the steel ball slide calliper rule precision after the welding repacking; The strength of each staff is different in detection; Degree of tightness is different, and the result who measures is also variant, finally causes checking the poor accuracy of size.Practical and accurately the raceway groove measuring instrument be the assurance of specification product.
Summary of the invention
Goal of the invention of the present invention is the deficiency that overcomes existing ball-cage constant velocity universal coupling raceway groove bottom of trench size detection instrument; And a kind of raceway groove measuring instrument is provided; Its two measuring point contacts with raceway groove and leans on the spring return to compress; Removed artificial factor, through dial gauge or clock gauge reading numerical values, degree of accuracy can reach 0.01 millimeter to the radix point three.
Technical program of the present invention lies in: a step-like central through hole is arranged in the guide-localization bar; The small stair nose end of guide-localization bar is equipped with the fixation measuring head, and the big step nose end of guide-localization bar is equipped with can be along the movable measuring head of guide-localization bar slip; Movable measuring head middle part is provided with spigot surface; Driving lever is fixed on the spigot surface at movable measuring head middle part; The guide-localization bar is provided with the allocating slot that matches with driving lever; One side opening that communicates with central through hole is arranged on the guide-localization bar; Guide pole vertically is loaded on the side opening of guide-localization bar; The sounding rod that can slide up and down along guide pole is housed in the guide pole; Push up with the gauge head of dial gauge or clock gauge mutually the sounding rod upper end, and steel ball is arranged at the sounding rod bottom, and steel ball pushes up with the front end of the movable measuring head that is used to promote to move on the steel ball mutually.
Said fixation measuring head and guide-localization bar are locked by set nut for being threaded.
Said guide pole is fixed on the guide-localization bar through two sunk screws.
Between the interior step of said spigot surface and guide-localization bar spring is arranged.
The spigot surface of said movable measuring head and guide-localization bar is little clearance fit.
The big step nose end of said guide-localization bar is provided with and cooperates spacing gland nut with spigot surface.
Be provided with the adjustment pad in the said gland nut.
The front end of said movable measuring head is 45 ° of inclined-planes that cooperate with steel ball.
The vertical moving amount of said steel ball equals the amount of moving horizontally of movable measuring head.
During measurement, stir driving lever, let two measuring heads fully contact, unclamp driving lever, the spring axial compression with the raceway groove bottom of trench with hand; The axial internal clearance of gauge head is moved by the other end 45 degree pushed steel balls of movable measuring head vertically, and steel ball promotes sounding rod and moves up and down, and the dial gauge or the clock gauge of sounding rod upper end reflect concrete reading, thereby measure the accurate size of raceway groove.Structural design of the present invention is novel, and unmanned is factor affecting, and measurement size is accurate, and result of use is desirable.
Description of drawings
The instance that provides below in conjunction with accompanying drawing further details the present invention.
Fig. 1 is the structural representation of existing steel ball slide calliper rule.
Fig. 2 is a structural representation of the present invention.
Among the figure, 1, the guide-localization bar, 2, the fixation measuring head, 3, set nut; 4, sunk screw, 5, steel ball, 6, guide pole, 7, sounding rod; 8, driving lever, 9, the adjustment pad, 10, gland nut, 11, movable measuring head; 12, spring, 13, dial gauge or clock gauge, 14, spigot surface, 15, allocating slot.
Embodiment
Among Fig. 2, a step-like central through hole is arranged in the guide-localization bar 1; Fixation measuring head 2 and guide-localization bar 1 small stair nose end be through being threaded, and by set nut 3 lockings; The movable measuring head 11 guide-localization bar 1 big step nose end of packing into, driving lever 8 is fixed on the spigot surface 14 at movable measuring head 11 middle parts through the allocating slot on the guide-localization bar 1 15 by screw thread; Movable measuring head 11 is by spring 12 axial compression, and spacing from big step nose end with gland nut 9 by adjustment pad 10; One side opening that communicates with central through hole is arranged on the guide-localization bar 1, and sounding rod 7 is packed in the guide pole 6, the sounding rod 7 lower end pits steel ball 5 of packing into, and guide pole 6 is fixed on the side opening place on the guide-localization bar 1 by two sunk screws 4.
