As shown in Fig. 3 (a)~4 (b), wherein Fig. 3 (a) is the front view of the pedestal 4, and Fig. 3 (b) is the top view of pedestal, It is the front view of base cover 3 as shown in Fig. 4 (a), Fig. 4 (b) is the top view of base cover, is provided with first on 3 side wall of base cover Connecting hole 13 is provided with the second connecting hole 14 on 4 barrel of pedestal, in order to enable pedestal 4 and base cover 3 are firm, it may include more A first connecting hole 13 and multiple second connecting holes 14, so that pedestal 4 and base cover 3 be enabled more can to consolidate fixed.

Specifically, the first fixing piece includes pin or screw.Using the first fixation member, so that pedestal 4 and base cover 3 exist Measurement is more firm when measuring tape rib inner ring.

Here screw or pin is provided to so that pedestal 4 and the fixation of base cover 3, not merely limitation screw or pin Nail, other any components for enabling to pedestal 4 and base cover 3 are not specifically limited herein.

Optionally, base cover 3 is provided with internal screw thread, and pedestal 4 is provided with external screw thread, and base cover 3 and pedestal 4 pass through screw thread It is connected and fixed.

As shown in Fig. 4 (a) and Fig. 5, optionally, raceway width measuring tool further includes the second fixing piece, is set in base cover 3 It is equipped with third connecting hole 15, the 4th connecting hole 16 is provided on the first connector 6, the second fixing piece passes through the third connecting hole 15 and 16 firm banking lid 3 of the 4th connecting hole and the first connector 6.

Specifically, second fixing piece includes screw or pin.

Here screw or pin is provided to so that base cover 3 and the fixation of the first connector 6, not merely limitation screw Or pin, other any components for enabling to base cover 3 and the first connector 6 are not specifically limited herein.

Be illustrated below with a kind of specific embodiment, as shown in fig. 6, the raceway width measuring tool include pedestal 4, Base cover 3, tong-test ammeter block 1 and dial gauge 5；

Wherein, pedestal 4 is the cylinder of both ends open, and hole is arranged on 4 barrel of pedestal, and the bottom of pedestal 4 is equipped with groove, Since there may be the substances such as the grinding wheel that should not be disposed ash, little particle on the rib with rib inner ring, using band groove structure Pedestal 4, will be in rib inner ring inserted base 4, during rotating cubing, under the influence of centrifugal force, institute on rib The substance of adherency can throw away the inside of pedestal 4 by groove, in order to avoid influence measurement result.

Hole is set on 3 side wall of base cover, and hole is arranged in the center point in base cover 3, on the right side of the center point hole It is square, another hole is additionally provided in base cover 3.

Tong-test ammeter block 1 is collectively constituted by rectangular block and fluting, and hole is arranged in the bottom of rectangular block, and screw 12 passes through fluting, The elastic of fluting is adjusted by turning screw 12.

Pin 18 passes through the hole on 4 barrel of hole and pedestal on 3 side wall of base cover, keeps base cover 3 and pedestal 4 solid It is fixed；Screw 17 passes through the hole of base cover 3 the center point hole and rectangular block bottom, keeps base cover 3 and tong-test ammeter block 1 fixed；Percentage The sleeve of table 5 passes through fluting, turns screw 12 and adjusts the elastic of fluting, so that dial gauge 5 and tong-test ammeter block 1 are fixed；Dial gauge 5 Another hole that gauge head passes through in base cover 3 protrudes into the inside of pedestal 4.

As shown in Figure 1, the gauge head of dial gauge 5 have passed through using ab as the highs and lows of the disc of diameter when measurement, Difference between highs and lows is the depth of parallelism, when the pointer of dial gauge 5 is directed toward zero-bit, the depth of parallelism zero.Due to height The raceway width of standard component is spent, i.e. the distance between bc in Fig. 1 is the depth of parallelism that is known, can measuring according to dial gauge, meter Calculation obtains the raceway width to be measured with rib inner ring.

First the Height Standard part as shown in Figure 1 with rib inner ring is put into pedestal 4, according to the height with rib inner ring Standard component adjusts the height of dial gauge 5, and the gauge head of dial gauge 5 is moved up and down in pedestal 4, until dial gauge 5 Gauge head is directed at the end face middle position of the Height Standard part with rib inner ring, then tightens the fixed dial gauge 5 of screw 12.Rotate cubing One week, the pointer of dial gauge 5 is transferred to zero-bit.

When measurement, band rib inner ring to be measured as shown in Figure 1 is put into pedestal 4, calibrates the survey of dial gauge 5 after zero-bit Head does not need to adjust again, and the gauge head of dial gauge 5 is directed at the end face middle position with rib inner ring, rotates cubing one week, percentage The total indicator reading of table 5 is the depth of parallelism to be measured with rib inner ring, if the depth of parallelism, in the margin of tolerance, band to be measured is kept off Side inner ring is qualified products；If the depth of parallelism exceeds the margin of tolerance, band rib inner ring to be measured is substandard product.

For example, the raceway width of the Height Standard part with rib inner ring is 27.000mm (millimeter), it is put into pedestal 4, school Quasi- zero-bit.Then band rib inner ring to be measured is put into pedestal 4, the pointer of dial gauge 5 deviates 5 lattice to the left (0.001 is every at this time Lattice), then the raceway width to be measured with rib inner ring calculates as follows: 27.000-5*0.001=26.995mm (millimeter).In parallel Degree is in tolerance permitted range, so the band rib inner ring to be measured is qualified products.

The embodiment of the present application also provides a kind of Automobile Parts Inspection devices, including above-mentioned raceway width measuring tool.

A kind of cubing of the measurement with rib inner ring raceway width provided by the embodiment of the utility model, including pedestal, pedestal Lid, tong-test ammeter block and dial gauge；The pedestal is the cylinder of both ends open, and the base cover lid is closed in one end of the cylinder, institute Stating tong-test ammeter block includes the first connector and the second connector；The tong-test ammeter block is solid by first connector and the base cover Fixed connection passes through the fixed dial gauge of second connector；Hole, the survey of the dial gauge are set in the base cover Head is protruded into the pedestal by described hole.Indirect measurement is generally taken to the measurement of raceway width in the prior art, that is, is surveyed The width and inner ring overall width for measuring rib, calculate raceway width by the calculation of dimension chain.Overall width and rib width The data of measurement be in the margin of tolerance, but the size of the raceway width obtained after subtracting each other may exceed the margin of tolerance, one It is a to be reduction of measuring accuracy；The other is product qualification rate is reduced, to guarantee the raceway width of product all in public affairs In poor range, needs to reduce the margin of tolerance of inner ring overall width and rib width very much, thus virtually improve processing The requirement of inner ring overall width and rib width.The application takes the one-shot measurement mode of directly measurement inner ring raceway width, avoids Intermediate conversion, improves measuring accuracy, improves product qualification rate.
