Abstract
A dedicated clamping apparatus for the finished polishing of test bars adopts the structure that at least one small hole is formed on a thick steel plate; the diameter of the small hole is equivalent to that of a test bar; the small hole is in clearance fit with the test bar; the parallelism tolerance between the upper end surface and the lower end surface of the clamping apparatus is within 0.01mm; and the squareness tolerance between the axial line of the small hole and the upper end surface of the clamping apparatus as well as that between the axial line of the small hole and the lower end surface of the clamping apparatus is within 0.01mm. The dedicated clamping apparatus has the advantages of simple structure and practical functions, and can be used in the finished polishing processes of the end surfaces of the test bars with smaller diameters, a larger number and higher precision; the use is very convenient; and a plurality of test bars can be processed in one step. Therefore, the work efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of coupon correct grinding special fixture.
Background technology
Our factory is sometimes received client's requirement will make some very little coupons, because coupon is too little, quantity is many, precision is high, has just made the anchor clamps of this special correct grinding coupon end face, thereby is convenient to processing.Therefore design this anchor clamps.
The utility model content
The utility model purpose is to provide a kind of coupon correct grinding special fixture, and working (machining) efficiency is higher.
To achieve these goals, the utility model adopts following technical scheme: coupon correct grinding special fixture, described anchor clamps be for being provided with at least one aperture having on the steel plate of thickness, the diameter of aperture and coupon diameter suitable and between be matched in clearance.
The parallelism tolerance of described anchor clamps upper and lower end face is in 0.01mm.
The squareness tolerance of the axis of described aperture and anchor clamps upper and lower end face is in 0.01mm.
The utility model is simple in structure, function is practical, in the coupon end face fine-grinding operation that can be used for that diameter is less, quantity is big, precision is higher, uses very conveniently, once can process a plurality of coupons, increases work efficiency greatly.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
Embodiment: shown in Fig. 1-2, coupon correct grinding special fixture adopts plain cast iron, and anchor clamps are for being provided with at least one aperture 2 on the steel plate 1 that thickness is arranged, the diameter of aperture 2 and coupon diameter suitable and between be matched in clearance.The parallelism tolerance of anchor clamps upper and lower end face is in 0.01mm.The squareness tolerance of the axis of aperture and anchor clamps upper and lower end face is in 0.01mm.Machining tolerance all in 0.01mm, can fully guarantee the requirement on machining accuracy of coupon.
These anchor clamps come the thickness of time anchor clamps calmly with the length of concrete coupon, guarantee that aperture size becomes matched in clearance with the coupon external diameter when processing aperture on anchor clamps.
The operation principle of these anchor clamps is: the size that hole diameter is worked into the coupon external diameter; The semi-finished product coupon is put into aperture, be placed on and finish grind end face on the surface grinding machine.
It is less that these anchor clamps are used for diameter, and quantity is bigger, in the higher coupon end face fine-grinding operation of precision.
Claims (3)
1. coupon correct grinding special fixture is characterized in that: described anchor clamps are for being provided with at least one aperture having on the steel plate of thickness, the diameter of aperture and coupon diameter suitable and between be matched in clearance.
2. coupon correct grinding special fixture according to claim 1, it is characterized in that: the parallelism tolerance of described anchor clamps upper and lower end face is in 0.01mm.
3. according to claim 1 or 2 arbitrary described coupon correct grinding special fixtures, it is characterized in that: the squareness tolerance of the axis of described aperture and anchor clamps upper and lower end face is in 0.01mm.
