Concentricity gauge

Technical Field

The invention relates to the field of shaft part detection, in particular to a concentricity detection tool.

Background

In the production and processing process of the shaft parts, the concentricity of the shaft parts needs to be detected, and the detection process is very important because the concentricity is an important technical index for evaluating the shaft parts and the error of the concentricity directly influences the assembly and the use of workpieces.

The existing concentricity detector is fixed on a supporting platform due to a clamping part, so that the concentricity detector cannot be adjusted according to the axial length of a part and is often limited by the type of the part, for example: patent CN204329874U discloses a axiality detection device, includes first holder, second holder, detects the table, still includes supporting platform, and first holder and second holder set up on supporting platform, the holder is used for the centre gripping to wait to detect the axle piece, and supporting platform plays the supporting role. During actual use, the center hole of the shaft to be measured is placed into the first clamping piece, then the spring resilience effect on the second clamping piece is utilized, the second clamping piece is clamped on the shaft to be measured, and finally the shaft is measured by using the detection meter. First holder and second holder are fixed to be located supporting platform in this patent, can't adjust the distance between two holders according to axle length.

Distance between two holders in above-mentioned scheme is in case set for, just can't change for when the model size of part is different, then need change suitable check out test set and detect, thereby cause the measurement cost to increase.

Through the setting, dwang and slide bar ability independent movement, the rotation that corresponds and the two mutual noninterference that slides, through the adjustable lift of slide bar, through dwang adjustable angle, operation process is simple and convenient, improves detection efficiency greatly, saves measuring time.

Preferably, as an improvement, the pouring weight is a switch type magnetic base, and the base is an iron plate.

Through the arrangement, the base is matched with the switch type magnetic base, when the switch is turned on, the switch type magnetic base is magnetic and can be tightly attached to the base, so that displacement and toppling over are avoided, and the stability of the detection device is improved. When the switch is turned off, the switch is easy to take, place and disassemble.

Preferably, as an improvement, the locking bolt is provided with an anti-slip protrusion at one end penetrating through the U-shaped clamping plate.

Through the setting, the antiskid is protruding can prevent that the dwang from sliding in rotating the piece, leads to detecting the table angle and changes, influences measuring result.
