Description
Technical field
The utility model is related to Piston Machining technical field, especially a kind of piston ring groove bottom footpath Special measuring instrument.
Background technology
Piston is an important part in engine, needs to measure the groove bottom diameter of piston during machining piston,
In order to reach measurement accuracy, generally groove bottom diameter is measured using cubings such as slide measure, micrometers at present, but above-mentioned measurer
Be inconvenient to find measurement position accurately, also inconvenient reading, measurement efficiency is relatively low in product batch production process.
The content of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is that piston can efficiently be measured by providing one kind
The piston ring groove bottom footpath Special measuring instrument of groove bottom diameter.
To achieve the above object, the utility model uses following technical scheme：
A kind of piston ring groove bottom footpath Special measuring instrument, it includes base, and the side of the base is along its length provided with more
Individual dial gauge, the gauge head of dial gauge points to the middle part of base for the annular groove end thereof contacts with tested piston, the multiple percentage
Table is set in different height, and the opposite side of the base is provided with multiple baseline rods with dial indicator measuring head coaxial line, the benchmark
Bar, which has, is used for the reference head with another end in contact of the annular groove, and the base is installed provided with corresponding with piston pin hole aperture
Bar, mounting rod is arranged on one piece of slide plate that can be slided along piston length direction, and the upper surface of base is along its length provided with cunning
Dynamic guide rail, slide plate is arranged on the rail plate, and the side of slide plate is provided with the drive device for driving the slide plate to be moved along the guide rail.
The drive device is cylinder, and the piston rod of cylinder and the side of slide plate are connected.
The baseline rod is connected by bearing with base, and bearing is provided with groove, and baseline rod passes through the groove, and baseline rod leads to
Cross with the groove relative slip to adjust the distance between reference head and gauge head, the bearing is provided with baseline rod and bearing
Fixed trip bolt.
The axis of the mounting rod is parallel with baseline rod or overlaps.
The utility model uses above technical scheme, by the cooperation of mounting rod and piston pin hole, piston is arranged on and slided
On plate, slide plate is driven by cylinder, piston is moved along base length direction, pass sequentially through each dial gauge, completed to piston
The measurement of each different groove bottom diameter, whole-process automatic completion drastically increases the measurement efficiency in piston ring groove bottom footpath.
Brief description of the drawings
The utility model is described in further details below in conjunction with the drawings and specific embodiments：
Fig. 1 is a kind of structural representation of piston ring groove bottom footpath Special measuring instrument of the utility model；
Fig. 2 is side structure schematic diagram of the present utility model.
Embodiment
As shown in accompanying drawing 1 or 2, the utility model includes base 1, and the side of the base 1 is along its length provided with multiple
Dial gauge 2, the gauge head of dial gauge 2 points to the middle part of base for the annular groove end thereof contacts with tested piston, the multiple percentage
Table 2 is set in different height, and the opposite side of the base 1 is provided with multiple baseline rods 3 with dial indicator measuring head coaxial line, the base
Quasi- bar 3, which has, is used for the reference head with another end in contact of the annular groove, and the base 1 is provided with corresponding with piston pin hole aperture
Mounting rod 4, mounting rod 4 is arranged on along one piece of slide plate 5 that can be slided along piston length direction, and the upper surface of base 1 is along length side
To provided with rail plate 6, slide plate 5 is arranged on the rail plate, and provided with driving, the slide plate 5 is transported along the guide rail 6 for the side of slide plate 5
Dynamic drive device 7.The drive device 7 is cylinder, and the piston rod of cylinder and the side of sliding block are connected.The baseline rod 3 leads to
Bearing is crossed to be connected with base 8, bearing be provided with groove 81, baseline rod 3 pass through the groove 81, baseline rod 3 by with the groove 81
Relative slip adjust the distance between reference head and gauge head, the bearing is provided with the fastening for fixing baseline rod and bearing
Screw 9.
The utility model is in use, by mounting rod insertion piston pin hole, by the cooperation of mounting rod and piston pin hole, incite somebody to action
Piston is arranged on slide plate, is driven slide plate by cylinder, piston is moved along base length direction, pass sequentially through each percentage
Table, completes the measurement of each different groove bottom diameter to piston, and whole-process automatic completion drastically increases the survey in piston ring groove bottom footpath
Amount efficiency.
