Abstract
The utility model relates to a rolling grinder for repairing a measuring surface of a measuring jaw of a height vernier caliper. According to the rolling grinder, a rolling combination body is installed on a working surface of a general grinder. During grinding, the grinder is pushed, pulled and swung back and forth to drive the rolling combination body to rotate freely, steel balls of the rolling combination body roll on the surface of a parallel circular truncated cone, and grinding of the measuring surface of the measuring jaw of the height vernier caliper is achieved. As the rolling grinder utilizes a rolling contact grinding method, grinding of the measuring surface of the measuring jaw can be independently conducted on a grinding flat plate, friction resistance is obviously reduced during grinding, time saving and labor saving are achieved during operation processes, and grinding quality is stable and reliable.
Description
Technical field
The utility model relates to the manufacturing field of machinery, fine measuring instrument and amount instrument.
Technical background
One, vernier height gauge, its blade are positioned at an end of base, and in use the base working face degree of wear of this end is larger, causes the out of plumb of base working face and blade basal plane and scale face, causes measuring jaw measurement face and base working face not parallel; Its two because the damage of vernier height gauge measuring jaw, behind the measuring jaw that need more renew, also can cause measuring jaw measure face and the base working face not parallel, more than either way can produce the larger error of indication, impact line precision.
The method of usually repairing vernier height gauge measuring jaw measurement face is: grind first vernier height gauge base working face, guarantee its flatness and with the blade basal plane with after the scale face is vertical, measuring jaw being measured face and base working face grinds at grinding flat plate simultaneously again, in process of lapping, should guarantee the vertical of base working face and blade basal plane and scale face, it is parallel with the base working face to guarantee that again measuring jaw is measured face, because the frictional resistance that grind this moment is larger, and also to take into account the reparation precision simultaneously, not only strengthen operation easier and detected number of times, also so that the quality of grinding is difficult for guaranteeing that it is much physical to have expended again the operator simultaneously.
Summary of the invention
The utility model technical issues that need to address are:
1. reduce the operation easier when grinding, improve the stability of Grinding Quality;
2. the frictional resistance when reducing to grind reduces operator's labour intensity;
3. avoid the wearing and tearing of grinding flat plate, guaranteed the precision of grinding flat plate.
The utility model solves its technical scheme: a working face at general mill (7) is installed a tourelle that is comprised of deep groove ball bearing (4), retainer turning cylinder (6) and steel ball (9), up and down two contact-making surfaces at steel ball are put into respectively two positioned parallel pads (8) and parallel round platform (2) suitable with ball hardness after the processing of quenching, the positioned parallel pad is fastened on the mill with fillister head screw (3) and is used in combination with check ring (5), can be to the deep groove ball bearing axial location.For fear of the damage of rolling steel balls and grinding flat plate (1), between steel ball and grinding flat plate, put into a parallel round platform with certain degree of hardness.During grinding, by the front and back push-and-pull and swing mill, the retainer turning cylinder is rotated and drive steel ball and roll at parallel round platform, realize that the rolling mill measures the grinding of face to the vernier height gauge measuring jaw.
The utility model produce an effect: this rolling mill has adopted the contact lapping mode that rolls, and can grind measuring jaw measurement face separately on grinding flat plate, so that frictional resistance obviously reduces, operating process saves time, laborsaving, and Grinding Quality is stable, reliable.

The specific embodiment
1. the assembling of rolling mill
The assembling of mill (7) and deep groove ball bearing (4), positioned parallel pad (8), check ring (5), retainer turning cylinder (6), steel ball (9): six isometrical steel balls are pressed into respectively in the hole prefabricated on the retainer turning cylinder, allow the steel ball on the retainer turning cylinder lie on the parallel round platform (2), the positioned parallel pad is installed on the retainer turning cylinder and with six steel balls contact; Deep groove ball bearing is fitted on the retainer turning cylinder and with the positioned parallel pad contacts; Again check ring is installed in the axial trough of retainer turning cylinder; Deep groove ball bearing is fitted in the manufactured dead eye of mill; The positioned parallel pad is fastened on the mill with four fillister head screws (3).
2. the debugging of rolling mill
The depth of parallelism of its upper surface and grinding flat plate (1) is not more than 0.005mm to the rolling mill under the duty grinding, all steel balls on the retainer turning cylinder should normally contact with parallel round platform peace row locating pad, and steel ball rotates flexibly, the rolling mill answers translation freely at parallel round platform.
3. the instructions for use of parallel round platform
The size of the diameter of parallel round platform and height visual-rolling mill and movement locus scope and decide, its material is alloy tool steel, and hardness is not less than HRC58 (suitable with ball hardness), and flatness is not more than 0.002mm, and the depth of parallelism is not more than 0.003mm.
4. the rolling mill grinds the operation that the vernier height gauge measuring jaw is measured face
Vernier height gauge is ground the qualified base of reparation be put on the grinding flat plate with parallel round platform, again the rolling mill is put on the parallel round platform, grinding agent evenly is coated on the mill working face.Adjust vernier height gauge measuring jaw height, and make on its abradant surface that is placed into the rolling mill, left hand is pinned the measuring jaw upper surface, abradant surface to mill applies suitable pressure, the right hand is pinched the cylindrical place of holding mill, under measuring jaw and parallel round platform keep motionless situation, firmly push-and-pull and swing mill vernier height gauge measuring jaw baseplane is ground.Process can select W20, W10 and W5 slightly to grind, carefully grind and lappingout according to field condition.For 0～1000mm vernier height gauge, its measuring jaw is measured the grinding precision of face: flatness should be not more than 0.003mm, should be not more than 0.006mm with the depth of parallelism of base working face, after the calibrating Grinding Quality is qualified, cleaning work is on-the-spot, finishes the whole process of grinding operation.
Claims (2)
1. a novel reparation vernier height gauge measuring jaw is measured the rolling mill of face, it is that a working face at general mill has installed a cover rolling assembly additional, and this structure is comprised of mill, retainer turning cylinder, steel ball, positioned parallel pad, deep groove ball bearing, check ring, fillister head screw and parallel round platform.
2. measure the rolling mill of face according to claim 1 described a kind of novel reparation vernier height gauge measuring jaw, it is characterized in that: up and down two contact-making surfaces at steel ball are put into respectively two positioned parallel pads and parallel round platform suitable with ball hardness after the processing of quenching.
