Abstract
The utility model discloses an inspection gauge for inspecting the size of a crank arm. The inspection gauge comprises a base (5) and a base nut which supports the base (5). The base (5) is provided with three cylindrical pins which inspect a crank arm to be inspected, a block (2) and a spline shaft (3). Distances among the cylindrical pins, the block (2) and the spline shaft (3) are determined according to the size of the crank arm to be inspected. A first cylindrical pin (1) and a second cylindrical pin (7) have different diameters, and the first cylindrical pin (1) and a third cylindrical pin have a same diameter. The inspection gauge with the above structure for inspecting the size of the crank arm can accurately inspect hole center distances and eccentric angles of various crank arm parts, and the measurement is simple and fast; at the same time, problems of low detection speed and artificial errors are overcome, and the operation is very convenient.
Description
Technical field
The utility model relates to a kind of cubing for the connecting lever dimension control.
Background technology
In prior art, processing enterprise generally adopts vernier caliper to be detected to the detection of the hole in piece part centre distance of connecting lever class, inspection to eccentric angle detects by projector, and dependence reviewer's knowledge, technical ability are that experience is carried out, this detection mode not only workload is very large, inefficiency, and measuring error is larger, is unfavorable for the carrying out of follow-up work.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of cubing for the connecting lever dimension control for problems of the prior art, its objective is centre distance and the drift angle problem of effective solution check connecting lever, improves the work efficiency of check.
The technical solution of the utility model base nut that to be this kind comprise base and base is supported for the cubing of connecting lever dimension control, described base is provided with at least one straight pin, block and the splined shaft that connecting lever to be tested is tested, and the distance between described straight pin, block, splined shaft is determined according to the size of connecting lever to be tested.
Described straight pin has three, is respectively the first straight pin, the second straight pin and three cylindrical pin.
Described the first straight pin is different with the diameter of the second straight pin, and the first straight pin is identical with the diameter of three cylindrical pin.
Described base is discoid or square.
This kind with said structure can accurately detect multiple connecting lever class hole in piece part centre distance and eccentric angle for the cubing of connecting lever dimension control, measures simple, quick; Simultaneously, overcome detection speed slow and have the problem of personal error, easy to operate.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
The assembling schematic diagram that Fig. 2 is the utility model the first duty.
The assembling schematic diagram that Fig. 3 is the utility model the second duty.
The assembling schematic diagram that Fig. 4 is the third duty of the utility model.
In Fig. 1-4,1: the first straight pin; 2: block; 3: splined shaft; 4: the second straight pins; 5: base; 6: the base nut.
Embodiment
Structure is in conjunction with known as shown in Figure 1, the base nut 6 that this kind comprises discoid or square base 5 and base 5 is supported for the cubing of connecting lever dimension control, base 5 is provided with at least one straight pin, block 2 and the splined shaft 3 that connecting lever to be tested is tested, and the distance between straight pin, block 2, splined shaft 3 is determined according to the size of connecting lever to be tested.
Straight pin has three, be respectively the first straight pin 1, the second straight pin 4 and three cylindrical pin 7, and the first straight pin 1 is different with the diameter of the second straight pin 4, and the first straight pin 1 is identical with the diameter of three cylindrical pin 7.
When workpiece is tested, with splined shaft 3 location, axle center, splined shaft 3 axle center are no more than 0.03mm to the deviation of centre distance between the first straight pin 1 and the second straight pin 4.
Fig. 2, for the assembling schematic diagram of the straight connecting lever of check, is contained in straight connecting lever to be tested on cubing and tests by splined shaft 3 and the first straight pin 1.
Fig. 3 is the assembling schematic diagram of the inclined to one side connecting lever of check, and inclined to one side connecting lever just to be tested is contained on cubing and tests by splined shaft 3 and three cylindrical pin 7, simultaneously the drift angle of inspection hole centre distance and axis and spline.
Fig. 4 is the assembling schematic diagram of check triangle connecting lever, triangle connecting lever just to be tested is contained on cubing and is connected location by splined shaft 3 with the second straight pin 4, first check the site error of the centre distance in two holes at the workplace of seeing work and block, site error allows to be no more than 0.2mm.
This kind with said structure can accurately detect multiple connecting lever class hole in piece part centre distance and eccentric angle for the cubing of connecting lever dimension control, measures simple, quick; Simultaneously, overcome detection speed slow and have the problem of personal error, easy to operate.
