Abstract
The utility model discloses a chain plate hole position degree detecting device, comprising a dial indicator (1) and a pedestal (2). The lower part of the pedestal (2) is equipped with a boss (3), the upper part of the pedestal is equipped with a dial indicator support (4), and the dial indicator (1) is arranged on the dial indicator support (4) vertically; the boss (3) is equipped with a T-shaped groove (8) of which the middle upper part is equipped with a chain plate supporting column (5), and the chain plate supporting column (5) is located right below a measuring rod of the dial indicator (1). The beneficial effects of the utility model are that the chain plate hole position degree detecting device is small in measurement error, is suitable for the chain plate hole position degree detection that the chain plate hole is not concentric with an excircle, and is simple in structure and convenient in operation.
Description
Technical field
The utility model relates to a kind of pick-up unit, especially relates to a kind of carrier bar hole location and detects device.
Background technology
The position degree of chain plate hole is to judge whether one of qualified important indicator of carrier bar.Position degree generally is to use kind of calliper, measures respectively the edge in hole with slide calliper rule to distance X 1, X2 and Y1, the Y2 value of carrier bar cylindrical, reduces value with X1-X2 or the large value of X2-X1(), Y1-Y2 or the large value of Y2-Y1(reduce value) draw position degree.But because of measuring error, especially when chain plate hole and cylindrical decentraction, slide calliper rule can't be symmetrical measures X1, X2 value, and drawn hole location will have very large error at this moment.
Summary of the invention
The purpose of this utility model provides a kind of carrier bar hole location detection device of measuring accurately and being applicable to chain plate hole and cylindrical decentraction.
For addressing the above problem, the technical scheme that the utility model is taked is:
A kind of carrier bar hole location detects device, comprise dial gauge and base, the base bottom is provided with boss, the top of base arranges dial indicator bracket, described dial gauge vertically is arranged on the dial indicator bracket, described boss is provided with "T"-shaped groove, and the middle and upper part of "T"-shaped groove is provided with the carrier bar support column, described carrier bar support column be positioned at the dial gauge sounding rod under.Carrier bar is placed on the support column and adjusts the position, and available dial gauge is measured the contact point of chain plate hole and support column to the air line distance of carrier bar cylindrical."T"-shaped groove mainly is that thereby unsettled hole and the support column of making of carrier bar contacts symmetry and the accuracy that guarantees measurement fully when measuring; And the terrace part on the boss is that carrier bar is in horizontality in order to guarantee to measure, and prevents the accuracy that the carrier bar obliquity effects is measured; Because the dial gauge traveling priority that the dial gauge sounding rod is small amplifies through gear drive, become to refer to the rotation of meter on index dial during reading, so convenient reading is accurate.
As further improvement of the utility model, described carrier bar support column is round pin, and described boss is provided with the circular hole that round pin is installed.The replacing after round pin weares and teares namely is convenient in the detachable installation of round pin and circular hole; Also be convenient to the replacing of the required round pin of different pore size carrier bar.
Further improve described round pin and circular hole interference fit as of the present utility model.It is compacter that interference fit is installed, and is difficult for becoming flexible, and makes measuring accuracy more guaranteed, more accurate, can control the magnitude of interference simultaneously, and the assurance round pin can be dismantled.
In sum, the beneficial effects of the utility model are: measuring error is little, applicable to the carrier bar hole location detection of chain plate hole and cylindrical decentraction, and also simple in structure, easy to operate.
Description of drawings
Fig. 1 is the schematic diagram that the utility model carrier bar hole location detects device.
Fig. 2 is that the P of Fig. 1 is to view.
Fig. 3 is the use view one that the utility model carrier bar hole location detects device.
Fig. 4 is the use view two that the utility model carrier bar hole location detects device.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Carrier bar hole location as depicted in figs. 1 and 2 detects device, comprise dial gauge 1 and base 2, base 2 bottoms are provided with boss 3, the top of base 2 arranges dial indicator bracket 4, described dial gauge 1 vertically is arranged on the dial indicator bracket 4, described boss 3 is provided with "T"-shaped groove 8, and the middle and upper part of "T"-shaped groove 8 is provided with carrier bar support column 5, described carrier bar support column 5 be positioned at dial gauge 1 sounding rod under.Described support column 5 is round pins, is provided with accordingly circular hole 6 on boss 3, circular hole 6 and round pin interference fit.
Concrete using method:
As shown in Figure 3, vertically hang over carrier bar 7 on the round pin, carrier bar 7 lower ends are unsettled and be stuck in the groove of vertical part of "T"-shaped groove 8, promote gently the sounding rod of dial gauge 1, contact the cylindrical of carrier bar 7 to the sounding rod of dial gauge 1, read the registration Y1 of dial gauge 1 this moment, then carrier bar 7 being turned upside down vertically hangs on the round pin, read the registration Y2 of dial gauge 1, get the difference of Y1 and Y2.
As shown in Figure 4, hang on the round pin carrier bar 7 and horizontal positioned, unsettled the hanging on the round pin of carrier bar 7 one ends this moment, the other end is supported by the level table of "T"-shaped groove 8.Promote gently the sounding rod of dial gauge 1, contact the cylindrical of carrier bar 7 to the sounding rod of dial gauge 1, read the registration X1 of dial gauge 1 this moment, use the same method again and measure this hole to the length X 2 of the cylindrical other end, the difference of getting X1 and X2.
The difference of the difference of foregoing X1 and X2 and Y1 and Y2 is used for the carrier bar hole location of expression carrier bar 7.
Make the magnitude of interference that the utility model carrier bar hole location detects device time control rounding pin and circular hole 6 interference fit, be convenient to the replacing of round pin, knock gently round pin with blunts such as hammers when needs are changed, it is taken off, the round pin that more renews gets final product.
