Technical Field

The utility model relates to an examine utensil, especially an axle type part surface roughness detection tool.

Background

When the surface roughness of some shaft parts is detected, a roughness detector is needed for operation. The thickness detector can be divided into two types, one is a large-scale detector used in a detection room environment, the size of the detector is large, and although the detection precision can be better achieved, the cost is very high;

the other type is a simple portable thickness gauge which is characterized by small volume, portability and high cost performance, but cannot detect shaft parts with steps, needs other auxiliary mechanisms for matching use and is difficult to ensure the detection accuracy. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, low cost can carry out the detection tool that the roughness detected to the axle type part that has the step.

The technical solution of the utility model is that: the utility model provides an axle type part surface roughness detection tool, includes mounting plate 1, its characterized in that: the detection jig is characterized in that a positioning strip 2 is arranged on the mounting base plate 1, a plurality of pairs of mounting holes 3 are formed in the mounting base plate 1 on two sides of the positioning strip 2, the V-shaped iron 4 can be fixed on the mounting base plate 1 through bolts penetrating into the mounting holes 3, a groove matched with the positioning strip 2 is formed in the bottom surface of the V-shaped iron 4, a supporting column 5 is arranged on the mounting base plate 1, the detection jig also comprises an elbow clamp 6, the elbow clamp 6 is connected to the supporting column 5 through a clamping piece 7, and the elbow clamp 6 is matched with the V-shaped iron 4,

the mounting base plate 1 is further provided with a Z-axis support frame 8, a lead screw 9 is rotatably supported in the Z-axis support frame 8, a hand wheel 10 arranged at the top end of the lead screw 9 is located above the Z-axis support frame 8, guide rods 11 are symmetrically arranged on two sides of the lead screw 9, a measuring head fixing seat 12 is connected on each guide rod 11 in a sliding mode, a nut block matched with the lead screw 9 is further arranged in each measuring head fixing seat 12, a clamping block 13 is arranged on the bottom end face of each measuring head fixing seat 12, a portable thickness gauge 14 is mounted in each clamping block 13, the central axis of the portable thickness gauge 14 and the central axis of the V-shaped iron 4 are located in the same longitudinal plane and are parallel to each other, and meanwhile the portable thickness gauge 14 can be detached from the clamping blocks 13.

Compared with the prior art, the utility model, have following advantage:

this kind of structural style's axle type part surface roughness detection tool, a structure is simple, design benefit, it is rationally distributed, it can't carry out the detection problem of the axle type part that has the step to portable roughness appearance, a special structure has been designed, it can the centre gripping and drive portable roughness appearance and move on vertical, it is fixed to utilize multiple fixed establishment will be surveyed axle type part simultaneously, and then realize the convenient of the axle type part that has the step, accurate roughness detection, it can also be adapted to the detection of the axle type part of multiple different specifications (certain length and diameter) simultaneously, the commonality is stronger. And the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: the utility model provides an axle type part surface roughness detection tool, includes mounting plate 1, its characterized in that: the detection jig is characterized in that a positioning strip 2 is arranged on the mounting base plate 1, a plurality of pairs of mounting holes 3 are formed in the mounting base plate 1 on two sides of the positioning strip 2, the V-shaped iron 4 can be fixed on the mounting base plate 1 through bolts penetrating into the mounting holes 3, a groove matched with the positioning strip 2 is formed in the bottom surface of the V-shaped iron 4, a supporting column 5 is arranged on the mounting base plate 1, the detection jig also comprises an elbow clamp 6, the elbow clamp 6 is connected to the supporting column 5 through a clamping piece 7, and the elbow clamp 6 is matched with the V-shaped iron 4,

The working process of the shaft part surface roughness detection jig with the structure form is as follows: firstly, a shaft part 15 to be detected is placed on a V-shaped iron 4, the shaft part 15 is pressed on the V-shaped iron 4 through an elbow clamp 6, then a hand wheel 10 is rotated, a measuring head fixing seat 12 is driven to move in the longitudinal direction through linkage of a lead screw 9 and a nut block, and as the central axis of a portable thickness gauge 14 and the central axis of the V-shaped iron 4 are in the same longitudinal plane and parallel to each other in the installation state, the movement finally drives the measuring head part of the portable thickness gauge 14 on a clamping block 13 to be in contact with the upper surface of the shaft part 15 so as to detect the roughness of the surface of the shaft part 15;

the portable thickness gauge 14 can be detached from the clamping block 13, so that the application range is wide; the portable thickness gauge 14 can be directly used under the condition that the portable thickness gauge 14 is required to be directly used, and when the portable thickness gauge 14 is required to be used for accurately measuring short shaft parts, the short shaft parts can be arranged on the clamping block 13 for detection;

meanwhile, if the shaft part 15 to be detected is provided with steps, the distance between the V-shaped iron 4 and the clamping block 13 can be adjusted by adjusting the mounting position of the V-shaped iron 4 on the mounting base plate 1, or the relative distance between the shaft part 15 and the clamping block 13 can be changed by adjusting the relative position of the shaft part 15 on the V-shaped iron 4, and the contact between the measuring head part of the portable thickness gauge 14 and the part to be detected on the shaft part 15 can be ensured by adjusting the height of the clamping block 13, so that the thickness detection of the shaft part 15 with the steps can be realized;

the V-shaped iron 4 is used for supporting the shaft parts 15 to be measured, so that the shaft parts 15 with different diameters can be measured, and when the shaft parts 15 with different diameters are replaced, the clamping piece 7 is only required to be opened, and then a proper position is selected and clamped on the supporting column 5 again.
