Description

A kind of crankshaft taper length-measuring appliance
Technical field
The present invention relates to a kind of tractor crankshaft tools, more precisely, being a kind of crankshaft taper length-measuring appliance.
Background technique
Crankshaft or crank parts set up tapered structure in output end, as shown in figure 4, length of the taper face to crank plane For taper length, general tolerance band is 0.2mm~0.3mm, and original detection method detects for vernier caliper or three coordinate measurements, Although vernier caliper measurement is convenient but because taper and bar diameter position are rounding off, measurement point is difficult to fix, and measurement misses in addition Difference, measured data are not accurate to the greatest extent, and three coordinate measurements belong to precision detecting instrument, need special inspection, and consuming time is long, really It is slow to recognize result, taper length value effectively cannot be obtained and be verified.
Summary of the invention
The present invention mainly solves technical problem present in the prior art, to provide a kind of crankshaft taper linear measure longimetry Device.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals:
A kind of crankshaft taper length-measuring appliance, which is characterized in that the crankshaft taper length-measuring appliance includes one Plate and a detection components, the detection components include a taper disk, and the edge of the upper surface of the taper disk is equipped with one Installation notch, the installation notch are equipped with a mounting hole, and the bottom centre of the taper disk is equipped with a perforative taper Taper chamber, the installation notch be equipped with a dismountable fixed block, the fixed block be equipped with one first fixation hole With one second fixation hole, first fixation hole is interior to be equipped with a dismountable dial gauge, and the lower section of the taper disk is equipped with One connection measuring rod, the inside of the described connection measuring rod are equipped with a connection screw thread hole, the pointer of the dial gauge with it is described Connection screw thread hole be fixedly connected, a fixing screws extend through second fixation hole and mounting hole.
Crankshaft taper length-measuring appliance of the invention has the advantage that crank class taper length detection dress of the invention Setting can rapidly and efficiently solve the problems, such as that vernier caliper measurement inaccuracy and three coordinate measurements are time-consuming and laborious, online to crankshaft or The taper length of crank class carries out detection confirmation, is managed with product quality, promotes product with stable quality, while also improving Production efficiency.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with It obtains other drawings based on these drawings.

Fig. 3 is the stereochemical structure decomposing schematic representation of the crankshaft taper length-measuring appliance in Fig. 1;
Fig. 4 is the schematic diagram of the taper size of crankshaft.
Specific embodiment
The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
As shown in Figure 1 to Figure 3, which includes a plate 3 and a detection components 2, the detection Component 2 includes a taper disk 5, and the edge of the upper surface of the taper disk 5 is equipped with an installation notch 51, which is equipped with One mounting hole 52, the bottom centre of the taper disk 5 are equipped with the taper chamber 10 of a perforative taper, which is equipped with one Dismountable fixed block 6, the fixed block 6 are equipped with one first fixation hole 61 and one second fixation hole 62, first fixation hole 61 It is inside equipped with a dismountable dial gauge 7, the lower section of the taper disk 5 is equipped with a connection measuring rod 8, the inside of the connection measuring rod 8 Equipped with a connection screw thread hole 81, the pointer of the dial gauge 7 is fixedly connected with the connection screw thread hole 81, and a fixing screws 9 are passed through respectively Wear second fixation hole 62 and mounting hole 52.
The specific application method of the crankshaft taper length-measuring appliance is described below, step is:
S1, plate 3 to be cleaned, the big end of crank 4 is flatted down and is lain in a horizontal plane on plate 3, it is ensured that taper direction is vertical, As shown in Figure 1;
S2, by the taper chamber 10 of taper disk 5 by crank taper rod diameter, be placed on crank 4, and by rotation adjustment with Ensure that the taper rod diameter of taper chamber 10 and crank 4 maximizes contact;
S3, keep taper chamber 10 with after crank taper rod diameter Full connected, the detection components that rotate in a circumferential direction manually 2 observe percentage The maximum value and minimum value of 7 pointer of table, i.e. the taper measurement of length value of crank 4.
Crank class taper device for detecting length of the invention can solution vernier caliper measurement inaccuracy rapidly and efficiently and The time-consuming and laborious problem of three coordinate measurements carries out detection confirmation to the taper length of crankshaft or crank class online, with product quality It is managed, promotes product with stable quality, while also improving production efficiency.
Not limited to this, any change or replacement expected without creative work should all be covered in guarantor of the invention Within the scope of shield.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
