Description

Multi-use inside diameter gauge

The utility model relates to a kind of measurer of the measurer of measuring annular wheel, particularly measuring tooth thickness.Be suitable for the processing and the check of annular wheel, measurement range is generally at 100～1500 millimeters.

Existing annular wheel is measured the two kinds of methods that adopt usually: a kind of termination that is tooth in the hole, adopt the vernier caliper measurement common normal, in the theoretical value of base tangent length with under the condition that the required number of teeth of striding has provided when measuring, near the length that measures the annular wheel reference circle according to the number of teeth of striding among the figure during measurement is base tangent length.Will be during measurement with move up and down slide calliper rule and of feel because the sum of errors of vernier caliper range estimation error makes measuring accuracy poor; Another kind is the depths of tooth in the hole, adopts the method for over pin measuring transverse tooth thickness, promptly two rollers is placed on two relative between cog of annular wheel, measure two distances between the roller surface with the internal diameter chi, meet among the figure and to require to be of a size of qualified, the data that this method records are still unreliable, and are difficult for grasping.

The purpose of this utility model is that a kind of measurer will be provided, and it can overcome above-mentioned shortcoming effectively, is convenient for measuring, and improves measuring accuracy and speed and has multiple function.

Utility model is achieved in that the ball method measuring principle according to a contact, have the two ends that externally threaded ball contact tip or sharp gauge head are arranged at measurer with two, gauge head one end and joint extension bar adjusting screw(rod) are with being threaded, the other end of gauge head is with being threaded on the sounding rod, make gauge head in gauge stand, become to endwisely slip with sounding rod, sounding rod is fastenedly connected with screw and change-over panel by spring, the table bar spindle nose of dial gauge and change-over panel near, except that adopting dial gauge, also can adopt clock gauge or electronic digital display apparatus.The table bar axle of dial gauge passes with gauge stand and makes all-in-one-piece cover seat circular hole and fastening with screw, and cover cap is connected with screw with the cover seat, and the two ends of gauge stand connect with round nut.

During measuring workpieces, when the gauge head compression spring shrinks, the distance that sounding rod slided will pass to table bar axle and will be reflected on the dial gauge by change-over panel, thereby reach the purpose of accurate measurement check annular wheel quality.

The utility model device compared with prior art, following advantage is arranged: measuring accuracy height, error are at 5 micrometer ranges, 6 class precisions that generally can be used for annular wheel are when manufacturing accuracy height and employing clock gauge even employing electronic digital display apparatus, along 5 class precisions that can be used for annular wheel; The influence that is not subjected to user's dynamometry easy to use, measuring speed soon, particularly to the measurement of dark endoporus and measured position in the endoporus depths; Have multiple functions such as footpath in the various annular wheel transverse tooth thickness of measurement, the internal thread, root footpath, diameter of bore and dedendum circle tapering.

The utility model is when the example structure that will describe in detail below adopting, and simple in structure, manufacturing is easy to operate easily.

Below with reference to accompanying drawing utility model is described in further detail.

Fig. 1 is the longitudinal sectional view of a kind of concrete structure of the utility model.

Fig. 2 is sharp gauge head front view.

Fig. 3 measures annular wheel internal diameter synoptic diagram.

Fig. 4 measures annular wheel transverse tooth thickness synoptic diagram.

Fig. 5 measures footpath synoptic diagram in the internal thread.

Fig. 6 is Fig. 1 annex scale longitudinal sectional view.

Fig. 7 is Fig. 1 annex centralising device longitudinal sectional drawing.

With reference to Fig. 1 Fig. 2 Fig. 6 Fig. 7, externally threaded a pair of steel ball gauge head of having of certain scuff resistance (1) or a pair of steel point gauge head (15) is arranged, be arranged at the two ends of measurer, gauge head one end and joint (2) extension bar (3) adjusting screw(rod) (4) are with being threaded, the other end of gauge head is connected with sounding rod (11) fastening with screw thread, make gauge head (1) or (15) in gauge stand (14), become to endwisely slip with sounding rod (11), the sounding rod of solid level shape (11) is fastenedly connected with screw (10) and change-over panel (9) by spring (12), the table bar spindle nose of dial gauge (5) and change-over panel (9) near, also can adopt the table bar diameter of axle size clock gauge or the employing electronic digital display apparatus identical with dial gauge (5) except that the dial gauge (5) that adopts prior art is.Circular hole and change-over panel (9) that the table bar axle of dial gauge (5) is passed on cover (8) seat place in the cover (8), to show the bar axle with screw (7) is fixed on cover (8) seat, cover (8) seat and gauge stand (14) can manufacture one, cover (8) covers and covers (8) seat with being threaded, and gauge stand (14) two ends are connected with (13) with round nut (6).

Above-mentioned measurer device is suitable for measuring the annular wheel more than 100 millimeters, during adjunction extension bar (3), and the annular wheel that the maximum detection amount is 1500 millimeters.When need measuring in the internal thread footpath or needing direct reading, must be after removing adjusting screw(rod) (4) and round nut (6), the scale annex that fit on is made up of cover (16) round nut (17) moving casing (18) and adjusting screw (19), but manufacturing accuracy requires height; When measuring diameter of bore, must go up cover and load onto the centralising device annex of being formed by spring (20) and centered cover (21), in this device,, make the gauge head of measurer find the endoporus maximum automatically owing to the effect of spring at gauge stand (14).The serial gauge head of ball contact tip (1), it will change along with the variation of module, such as modulus 1～20, can change use in the steel ball of 20 pairs of different-diameters, and ball contact tip is mainly used to measure in annular wheel transverse tooth thickness and the internal thread footpath etc.Point gauge head (15) is used for measuring annular wheel root footpath, diameter of bore and dedendum circle tapering etc.The material of measurer: adjusting screw(rod) extension bar change-over panel sounding rod gauge stand etc. adopt tool steel, and spring adopts spring steel, and gauge head particularly ball contact tip adopts alloy steel.General operation and machining manufactures such as measurer is processed and adopted car, grinds, mills, brill, pincers, only a pair of gauge head (1) or (15), joint (2), extension bar (3), adjusting screw(rod) (4), sounding rod (11) must be installed on the same axis, and the gap between the internal diameter of the external diameter of sounding rod (11) and gauge stand (14) should be in 0.007～0.015 millimeter.

The utility model device can have multiple structure and specification, but operates identically, grasps easily.

With reference to Fig. 3 Fig. 4 Fig. 5, at first according to the theoretical size of measured workpiece, on the external diameter chi, accurately proofread and correct during operation, proofread and correct the back and break away from before the external diameter chi, write down dial gauge or clock gauge reading maybe with the minute hand of table to zero; Secondly this measurer is positioned over the moderate position of measured workpiece, one fixing, and one of sounding rod band spring is moved gently, and number is minimum to get final product when table upward shows; The data that to proofread and correct on the external diameter chi add or deduct reading on the table at last, promptly get the actual measurement size of workpiece.
