Description
Technical field:
The utility model relates generally to the anchor clamps field, relates in particular to cylindrical straight gear duplicate gear elasticity and clamps the grinding out anchor clamps.
Background technology:
The cylindrical straight gear duplicate gear adds man-hour with grinding machine it being carried out endoporus, the cylindrical straight gear duplicate gear need be clamped, and not so can have influence on the machining accuracy of product endoporus.So, need to guarantee the special fixture of processing precision of products.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of cylindrical straight gear duplicate gear elasticity to clamp the grinding out anchor clamps.
The utility model is achieved through the following technical solutions:
Cylindrical straight gear duplicate gear elasticity clamps the grinding out anchor clamps, it is characterized in that: the clamp body that includes tubular, the annular inner wall of described clamp body is provided with the top bar hole and the hole of getting out of a predicament or an embarrassing situation, on described, the hole of getting out of a predicament or an embarrassing situation is internal taper hole, the oral area in the described hole of topping bar is set with the small end clamping ring that has male cone (strobilus masculinus), the tapering coupling of internal taper hole on the tapering of the male cone (strobilus masculinus) of described small end clamping ring and the hole of topping bar, the oral area in the described hole of getting out of a predicament or an embarrassing situation is set with the big end clamping ring that has male cone (strobilus masculinus), the tapering coupling of internal taper hole on the tapering of the male cone (strobilus masculinus) of described big end clamping ring and the hole of getting out of a predicament or an embarrassing situation, the outside oral area of described big end clamping ring is with big end and keeps circle; Include and compress end cap, describedly compress end cap to be sleeved on clamp body outer and its inner face is pressed in big end back-up ring and big end keeps on the outer face of circle.
Described cylindrical straight gear duplicate gear elasticity clamps the grinding out anchor clamps, and it is characterized in that: described small end clamping ring the inner is provided with the annular edge edge, and described annular edge is inserted with small end pitch circle rod along being provided with perforate in the described perforate.
Described cylindrical straight gear duplicate gear elasticity clamps the grinding out anchor clamps, it is characterized in that: described big end keeps circle to be provided with through hole, is inserted with big end pitch circle rod in the described through hole.
Clamp body and grinding machine spindle transition disc convex shoulder adopt interference fits, and fastening with screw, and the runout tolerance of clamping fixture for correcting body inner conical surface is less than 0.01mm before the grinding.Small end pitch circle rod on the small end clamping ring, holds the pitch circle rod to keep on the circle at big end with the steady pin riveted with the steady pin riveted greatly.Workpiece is vertical earlier before the clamping inserts in the small end clamping ring pitch circle rod, inserts big end pitch circle rod again, and putting into behind the clamp body turns clockwise with specific purpose tool compresses end cap, thereby promotes big or small clamping ring clamping work pieces, can begin inner hole grinding.After workpiece grinds, be rotated counterclockwise to unload and compress end cap, insert the big end of clamp body lateral aperture sledge pine with specific purpose tool again or the small end clamping ring is released workpiece.
Described clamp body selects for use the energy heat-treatment quenching to Fine Steel Casting iron more than the HRC55 or steel alloy, and the design inner conical surface is 2.5 °, heat treatment hardness 58～62HRC.By means of connecting transition disc, clamp body is installed on grinding machine spindle, with the clamp body of grinding machine internal taper hole own, make its conical surface run-out tolerance be not more than 0.01mm, surface roughness value Ra=0.8 μ m.
Described large and small end pitch circle rod is selected the T10A material for use, heat treatment hardness 58～62HRC, and cylindricity tolerance 0.005mm, surface roughness Ra=0.8 μ m, 3 one group of pitch circle rod outside diameters must be consistent, must not differ to surpass 0.005mm.The position of pitch circle rod: if the gear number of teeth is 3 multiple, then the pitch circle rod keeps uniform on the circle at small end clamping ring and big end.If not 3 multiple, then be arranged in 1/3 circumference of gear place nearby on the position of teeth groove.
Described big small end clamping ring is selected the 65Mn material for use, heat treatment hardness 45～50HRC.Earlier grinding endoporus location mill male cone (strobilus masculinus), and with clamp body inner conical surface match grinding, contact-making surface is no less than 80%, is respectively charged into mill endoporus in the clamp body again, makes its endoporus run-out tolerance be not more than 0.01mm, endoporus and male cone (strobilus masculinus) surface roughness Ra=0.8 μ m.Because after clamping, shrink in the aperture, so have the wide groove of 4mm vertically at the conical surface, this groove is treated to sever after male cone (strobilus masculinus) and endoporus grind again, and severs its interior hole dimension of back and increases about 0.5mm.For guaranteeing that big small end locatees clamping synchronously, should notice during match grinding guaranteeing that big or small clamping ring end face exceeds 3～4mm than clamp body end face.
Determining of size pitch circle rod diameter and big small end clamping ring diameter of bore: roller diameter and outer common tangent circle Diameter Calculation formula in the time of can locating according to " jig design manual " straight spur gear profile of tooth calculate.The pitch circle rod diameter that is calculated by formula rounds and is actual pitch circle rod diameter, and it is hole dimension in the clamping ring that the outer common tangent circle diameter that is calculated by actual pitch circle rod diameter is got minimum of a value.
The utility model has the advantages that:
The utility model is simple in structure, and manufacturing expense is low, handling ease, convenient mounting and clamping.The gear-wheel gear-ring circular runout of the utility model processing can be stabilized in 9 grades with interior (JB179-83).
