Abstract
The invention discloses a kind of automobile leaf spring grasswort monolithic semifocal chord length-measuring appliance, and guide rail is provided with the both sides edge length direction of platform base, and transverse strands are provided with positioning sliding block on guide rail, and positioning sliding block is provided with locating taper pin；It is chute between guide rail；One end of guide rail is provided with positioning seat, and positioning seat is provided with alignment pin；The lateral surface of guide rail is provided with graduated scale；Positioning seat is open type positioning seat, and corresponding alignment pin is connected in open type positioning seat.Platform base is datum plane in the present invention, and for determining perpendicularity and depth of parallelism benchmark, positioning sliding block coordinates the central axis of the accurate centering automobile leaf spring centre bore of locating taper pin；Coordinate the central axis in the accurate centering automobile leaf spring grasswort hole of open type positioning seat in alignment pin insertion roll of steel plate earhole, locating taper pin coordinates positioning sliding block to be slidably reciprocated according to half different chord length of steel plate, measured；Accurate reading can be facilitated by the graduated scale of the lateral surface of guide rail.
Description
Technical field
The present invention relates to the detection of automobile leaf spring, specially a kind of automobile leaf spring grasswort monolithic semifocal chord length-measuring appliance.
Background technology
Current domestic leaf spring industry does not have the semifocal chord measuring tool for measuring length that half chord length of special spring eye of vehicle plate spring monolithic quickly measures measurer, only assembly.
Spring eye of vehicle plate spring monolithic semifocal chord measurement of length method is:To use straight steel ruler throughput axis pin of column, by square proportion center pore radius axis, to measure the mode of half chord length.Measurement needs more people in this way while operational measure is multiple, and not only operating efficiency is low, and because of bad alignment hole datum axis, misses by a mile.Its degree of accuracy measured depends on the technical ability of operator, and the degree of accuracy of measurement is not easy to ensure, can not meet required precision of the client to product, can not use in batches.
The content of the invention
The present invention quickly measures half chord length of automobile leaf spring grasswort monolithic in order to one, improves operating efficiency and measurement accuracy, and spy proposes a kind of automobile leaf spring grasswort monolithic semifocal chord length-measuring appliance.
For this technical scheme is that, a kind of automobile leaf spring grasswort monolithic semifocal chord length-measuring appliance, an including platform base, it is characterised in that：Guide rail is provided with the both sides edge length direction of the platform base, transverse strands are provided with positioning sliding block on guide rail, and positioning sliding block is provided with locating taper pin；It is chute between guide rail；One end of guide rail is provided with positioning seat, and positioning seat is provided with alignment pin；The lateral surface of guide rail is provided with graduated scale.
Further improve is：Positioning seat is open type positioning seat, and corresponding alignment pin is quickly connected in open type positioning seat.
Beneficial effect：
Platform base is datum plane in the present invention, and for determining perpendicularity and depth of parallelism benchmark, positioning sliding block coordinates the central axis of the accurate centering automobile leaf spring centre bore of locating taper pin；Coordinate the central axis in the accurate centering automobile leaf spring grasswort hole of open type positioning seat in alignment pin insertion roll of steel plate earhole；Locating taper pin coordinates positioning sliding block to be slidably reciprocated according to half different chord length of steel plate, measures；Being capable of accurate reading by the graduated scale of the lateral surface of guide rail.
Locating taper pin is used for the centre bore axis of centering different pore size.
Graduated scale is used for reading half chord values on the outside of guide rail.
Steel plate grasswort monolithic is rapidly put on platform base when in use coordinates open type positioning seat to find grasswort hole center reference by pin；Open type positioning seat facilitates the quick clamping installation of alignment pin.
The present invention solves the problems, such as quick and precisely find steel plate centre bore and grasswort axially bored line benchmark；Solve the problems, such as that grasswort centre bore axial reference can not be measured quickly with two looking somebody up and down axis pin of column contraposition efficiency are low；Solve the problems, such as to need more people's operation repeatedly measurements during measurement；It is big to solve error in reading, and the problem of efficiency is low.
Only one people's operational measure of needs, a fast accurate is looked for, measurement is rapid, and accuracy of reading precision is high, and measurement range all covers all products at present, cost-effective, meets consumer product technological requirement.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the use state diagram of the present invention.
1 is platform base in figure, and 2 be alignment pin, and 3 be open type positioning seat, and 4 be guide rail, and 5 be chute, and 6 be positioning sliding block, and 7 be locating taper pin, and 8 be graduated scale, and 9 be automobile leaf spring.
Embodiment
The present invention is as shown in Figure 1, 2.
A kind of automobile leaf spring grasswort monolithic semifocal chord length-measuring appliance, including a platform base 1, guide rail 4 is provided with the both sides edge length direction of the platform base 1, transverse strands are provided with positioning sliding block 6 on guide rail 4, and positioning sliding block 6 is provided with locating taper pin 7；It is chute 5 between guide rail 4；One end of guide rail 4 is provided with positioning seat, and positioning seat is provided with alignment pin 2；The lateral surface of guide rail 4 is provided with graduated scale 8.
Positioning seat is open type positioning seat 3, and corresponding alignment pin 2 is connected in open type positioning seat 3.
The grasswort monolithic of automobile leaf spring 9 is rapidly put on platform base 1 when in use coordinates open type positioning seat 3 to find grasswort hole center reference by alignment pin 2；Open type positioning seat 3 facilitates the quick clamping installation of alignment pin.
Without departing from the structure of the invention, several modifications and improvements can also be made, these should also be considered as protection scope of the present invention, these effects and practical applicability for implementing all without the influence present invention.
