Background

In the production process of the shaft in the workshop, the circular runout tolerance and the length tolerance of the produced shaft are required to be measured, and at the moment, the shaft is required to be measured by two instruments, namely a runout measuring instrument and a vernier caliper. However, when a shaft with steps is encountered, the radial run-out of the shaft cannot be measured due to the fact that the run-out measuring instrument is not provided with an up-down lifting fine adjustment device; when the length of the shaft is long, the vernier caliper cannot measure the length of the shaft, the precision of the vernier caliper with a large range cannot meet the precision of the shaft required in the market, the vernier caliper with a large range is not easy to move, measurement personnel are difficult to carry when measuring the shaft, the measurement error is large, and the operation cannot be performed with ease.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: a fine adjustment device which can be adjusted up and down is added, so that the shaft of the ladder type can be used for measuring the circular runout.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a circle length measuring appearance that beats, includes board bearing frame, base main part, circle measuring mechanism and length measurement mechanism that beats all arranges in on the accurate linear ball guide of both sides on the base main part workstation, be equipped with the oscilaltion displacement platform on the circle measuring mechanism that beats, the oscilaltion displacement platform is located the circle and beats under the testboard, arranges in on the accurate linear ball guide through solid fixed sliding block on, be equipped with lifting button and quick locking handle on the oscilaltion displacement platform, lifting button control the circle testboard that beats goes up and down, quick locking handle control circle testboard translation that beats.

Compared with the prior art, the beneficial effects of the utility model are that: 1. the base main body is made of natural granite, so that the influence of the deformation of the base main body on the measurement of the shaft is avoided; 2. a high-grade precise linear ball guide rail is adopted, so that the run-out is stable and the run-out is small, and the measurement error is small; 3. measuring person

The operation of the operator is convenient.

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.

FIG. 1 is a schematic diagram of the main structure of a circle run-out length measuring instrument in the embodiment;

FIG. 2 is a schematic diagram of a circle run-out measuring structure of the circle run-out length measuring instrument in the embodiment.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

As shown in fig. 1-2, a circle run-out length measuring instrument comprises a machine table bearing frame 2, a base main body 3, a circle run-out measuring mechanism and a length measuring mechanism, wherein the circle run-out measuring mechanism and the length measuring mechanism are arranged on precise linear ball guide rails 13 on two sides of a table top of the base main body 3, an up-down lifting displacement table 8 is arranged on the circle run-out measuring mechanism, the up-down lifting displacement table 8 is positioned below the circle run-out testing table 7 and is arranged on the precise linear ball guide rails 13 through a fixed slide block, a lifting button 5 and a quick locking handle 4 are arranged on the up-down lifting displacement table 8, the lifting button 5 controls the circle run-out testing table 7 to lift, and the quick locking handle 4 controls the circle run-out testing table 7 to move horizontally. In the embodiment, in order to realize the self leveling of the whole instrument, the horizontal adjusting foot support 1 is arranged below the machine platform bearing frame 2, and when the platform surface of the base main body 3 is uneven, the horizontal adjusting foot support 1 is adjusted to level the base main body; because the span of the whole working table is large, the base main body is easy to deform, and the measurement result is influenced, in order to solve the problem, in the embodiment, the base main body 2 adopts natural granite; the workpiece part is clamped at the upper end of the circular bounce test table 7, and a clamping part is formed by two circular block parts, so that the workpiece to be measured can rotate more easily in the clamping part, and the measurement error is reduced. The length measuring mechanism comprises a reference block 6, a digital display meter 11, a measuring claw 10 and an open grating ruler 12, wherein the reference block 6 is positioned at the edge of the table top of the base main body 3, the digital display meter 11 and the measuring claw 10 are both arranged on a sliding block support, the sliding block support is arranged on the precise linear ball guide rail 13, and the open grating 12 and the guide rail are arranged on the base main body 3 in parallel; the measuring claw 10 can stretch out and draw back along the vertical direction of the guide rail to measure the length of the workpiece, and the two ends of the precision linear ball guide rail 13 are respectively provided with a travel stop 14 to prevent the equipment from being damaged due to excessive travel.

The working principle of the assembling equipment is as follows:

checking whether the working table is horizontal or not, if the working table is not in a horizontal state, adjusting the horizontal adjusting foot support 1 to enable the working table to be horizontal, slightly placing a workpiece to be measured on a clamping part of the circular runout test table 7, when the radial runout of the shaft workpiece is measured, moving the dial gauge 9 to the highest point of the outer surface of the shaft workpiece, measuring the straightness of the dial gauge along the axial direction of the shaft, and when the errors of two ends of the straightness are large, moving the lifting displacement table 8 up and down by adjusting the lifting knob 5 until the straightness of the shaft workpiece is kept within 0.005 mm. After the straightness of the shaft is adjusted, the lifting displacement table 8 is fixed by twisting the quick handle, then an operator rotates the surface of the shaft workpiece, the radial runout value of the shaft workpiece is observed through a dial indicator, and the maximum value of the dial indicator is the radial runout value of the shaft. When the length dimension of the shaft workpiece is measured, the measuring claw 10 moves to the side surface of the reference block 6 from the left end, the digital display meter is reset to zero at the position, the zero position is the left end surface of the shaft workpiece to be measured, the measuring claw moves to the right end direction, the numerical value on the digital display meter 11 is read when the measuring claw moves to the right end surface of the shaft, and the numerical value is the length dimension of the shaft workpiece.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
