Abstract
The utility model discloses a verticality measuring instrument for a roller bearing holding rack beam, which comprises a circular dial indicator and a measuring head. The verticality measuring instrument is characterized in that the measuring head is arranged on a measuring head block at the top end of a vertical L-shaped equal-distance lever connected from the circular dial indicator; and a moving measuring head and a fixed measuring head are arranged on the measuring head. The utility model has the benefits that the verticality measuring instrument for the roller bearing holding rack beam has simple structure, is convenient to use and can be used for directly and visually reading the number.
Description
Technical field
The utility model relates to a kind of surveying instrument, particularly discloses a kind of roller bearing retainer beam verticality measuring instrument, is applicable to the bearing manufacture field.
Background technology
Because the space, pocket hole of roller bearing retainer is narrow and small, so still there is not the special measurement instrument of roller bearing retainer beam verticality at present.The machining precision that generally is dependence equipment guarantees, or adopts the high-accurate outline instrument of measuring room to measure, and not only efficient is lower, and measuring accuracy is difficult to guarantee.
Summary of the invention
The purpose of this utility model is to solve a prior art difficult problem, discloses a kind of roller bearing retainer beam verticality measuring instrument, and two gauge heads are set, and measures the data of the variation acquisition roller bearing retainer beam verticality of measurement point by gauge head.
The utility model is achieved in that a kind of roller bearing retainer beam verticality measuring instrument, comprise circular dial gauge and gauge head, it is characterized in that: described gauge head is arranged on the gauge head piece on the vertical L shaped equidistant lever top that is picked out by circular dial gauge, and described gauge head is provided with movable gauge head and fixing gauge head.Described gauge head piece stretches in the pocket hole of retainer, and its size is complementary with the pocket hole of retainer.
The utility model adopts two gauge heads that keep certain distance, one of them is movable gauge head, one is fixing gauge head, utilize standard gauge with movable gauge head and fixedly the axial location of gauge head demarcate and to be zero-bit, then the gauge head piece is stretched in the pocket hole of roller bearing retainer, when the beam of roller bearing retainer tilts, just make movable gauge head displacement, by movable gauge head the variation of measurement point is delivered to instrument, thereby obtains the data of roller bearing retainer beam verticality.
Principle of work of the present utility model is: choose suitable gauge head piece according to retainer pocket hole depth of beam, measure overall height as far as possible, on dressing plate with L shaped standard gauge movable gauge head and fixedly the axial location of gauge head to demarcate be zero-bit, adopt the general little pin of circle dial gauge to press two circles (making movable gauge head have two-way scope of activities); The retainer that desire is surveyed is placed on the dressing plate, and the gauge head piece stretched in the retainer pocket hole, the bottom of gauge head piece does not contact with the bottom of retainer, make gauge head rely on cage bar (being positioned at the centre of retainer external diameter), by dial gauge read data be exactly the verticality of cage bar to the bottom surface.
The beneficial effects of the utility model are: the utility model roller bearing retainer beam verticality measuring instrument is simple in structure, easy to use, and reading numerical values is straightforward.
Description of drawings
Probe part side view when Fig. 1 is the utility model measurement state.
Fig. 2 is that the utility model is measured view.
Embodiment
With reference to the accompanying drawings 1 and 2, a kind of roller bearing retainer beam verticality measuring instrument comprises fixedly gauge head 1 of 2, of circular dial gauges 4, movable gauge head, and gauge head is arranged on the gauge head piece 3 on the vertical L shaped equidistant lever top that is picked out by circular dial gauge 4.Keep certain distance between two gauge heads.
During measurement, with magnetic force dial framework or other modes that the utility model is unsettled, and make gauge head piece 3 bottoms a little more than bottom surface, survey roller bearing retainer 5 pocket hole, select different gauge head pieces 3 according to the size in roller bearing retainer 5 pocket holes.Utilize standard gauge that the movable gauge head 2 and the fixing axial location of gauge head 1 are demarcated and be zero-bit, the movable gauge head 2 and the fixing line of gauge head 1 are demarcated to perpendicular to reference field.Roller bearing retainer 5 to be measured is placed on the flat board, then gauge head piece 3 is stretched in the pocket hole of roller bearing retainer 5, make two gauge heads be close to cage bar middle part radially, position consistency when the little pin of circle dial gauge and his-and-hers watches.When the beam of roller bearing retainer tilts, just make movable gauge head 2 displacements, by movable gauge head 2 variation of measurement point is delivered to circular dial gauge 4, thereby obtains the data of roller bearing retainer 5 beam verticality.The big shown numerical value of indicator promptly is the verticality of cage bar to the retainer base.
Claims (2)
1. roller bearing retainer beam verticality measuring instrument, comprise circular dial gauge and gauge head, it is characterized in that: described gauge head is arranged on the gauge head piece on the vertical L shaped equidistant lever top that is picked out by circular dial gauge, and described gauge head is provided with movable gauge head and fixing gauge head.
2. roller bearing retainer beam verticality measuring instrument according to claim 1 is characterized in that: described gauge head piece stretches in the pocket hole of retainer, and its size is complementary with the pocket hole size of retainer.
