Description

The special of a kind of Rear Axle Steel Plate spring suppport hole centre distance tests tool
Technical field
The utility model relates to auto parts and components instruments of inspection technical field, is specifically related to the special of a kind of Rear Axle Steel Plate spring suppport hole centre distance and tests tool.
Background technology
At present, on truck, major part all uses leaf spring as shock mitigation system, to improve automobile stability under steam.For installing leaf spring, usual needs arrange dumb iron in vehicle bridge, for guaranteeing the stability after leaf spring assembling and serviceable life, require that the bracket holes deviation of centre distance after dumb iron and rear axle housing assembly welding can not be greater than 1mm, but in actual production manufacture process, due to the interference of axle housing, this pitch of holes is difficult to conventional ruler, tape measure and slide calliper rule carry out Measurement accuracy, inadequate measurement or convert after numerical value also incorrect, and axle housing and dumb iron all have multiple assembling parts to be welded into, certain welding deformation is inevitably produced in manufacture process, so before axle case assy is used for assembling, accurately must measure pitch of holes, avoid follow-up reprocessing.
Summary of the invention
The purpose of this utility model be to provide a kind of structure simple, easy to operate, different size pitch-row can be met measure that the Rear Axle Steel Plate spring suppport hole centre distance of needs is special tests tool.
The purpose of this utility model realizes like this, comprise supporting plate, stationary positioned post and adjustable reference column, supporting plate one end is vertically installed with stationary positioned post, the other end is processed with the chute of strip, bar hole is processed with bottom chute, adjustable reference column upper end is fixedly connected with slide block, and the epimere cylinder of adjustable reference column is processed with external thread, and adjustable reference column is threaded with clamp nut after passing perpendicularly through bar hole.Supporting plate is marked with scale mark, and the start index of scale mark is arranged on the center of stationary positioned post.Tongue upper surface is provided with measured value pointer, the position of measured value pointer is the center of adjustable reference column.
The utility model adopts reference column that the central point of bracket holes is extended to certain altitude, can realize the measurement to pitch of holes with routine measurement instruments such as rulers, overcomes the problem that axle housing is interfered, achieves the accurate measurement of pitch-row; Additionally by the adjustable reference column that one of them reference column is set to be free to slide on supporting plate, effectively simplify the operation that on bracket holes, each group pitch of holes is measured, significantly provide surveying work efficiency; The utility model structure is simple, easy to operate, can meet different size pitch-row measure needs, measure efficiency and precision high, there is good application value.

Fig. 4 is the schematic diagram that the utility model measures minimum aperture spacing state;
In figure: 1-stationary positioned post, 2-supporting plate, 3-bar hole, 4-chute, 5--is adjustable reference column, 6-clamp nut, 7-slide block, 8-start index, 9-measured value pointer, 10-scale mark, 11-dumb iron, 12-rear axle housing.
Embodiment
Be further described the utility model below in conjunction with accompanying drawing, but limited the utility model never in any form, any change done based on the utility model training centre or improvement, all belong to protection domain of the present utility model.
As Figure 1-4, the utility model comprises supporting plate 2, stationary positioned post 1 and adjustable reference column 5, supporting plate 2 one end is vertically installed with stationary positioned post 1, the other end is processed with the chute 4 of strip, bar hole 3 is processed with bottom chute 4, adjustable reference column 5 upper end is fixedly connected with slide block 7, and the epimere cylinder of adjustable reference column 5 is processed with external thread, and adjustable reference column 5 is threaded with clamp nut 6 after passing perpendicularly through bar hole 3.The size of slide block 7 coordinates with chute 4, and the gap between the edge of slide block 7 and chute 4 is 0.5-1mm, and slide block 7 can free, stable reciprocatingly sliding on chute 4.The width 0.1-0.3mm larger than the external diameter of adjustable reference column 5 of bar hole 3, the length of bar hole 3 can be determined according to the maximum spacing of pitch of holes workpiece to be measured and the difference of minimum spacing.During use, first stationary positioned post 1 is inserted in one of them metering-orifice to be measured fixing, then by the slide block 7 in slip chute 4, mobile adjustable reference column 5 is to the position of another measured hole, mobile adjustable reference column 5 inserts after in measured hole, and tightening clamp nut 6 can fix adjustable reference column 5 with supporting plate 2, now measures the central point of stationary positioned post 1 and adjustable reference column 5 upper end, the centre distance obtaining two holes on dumb iron 11 can be measured, avoid the interference of rear axle housing 12.
Further, supporting plate 2 is marked with scale mark 10, the start index 8 of scale mark 10 is arranged on the center of stationary positioned post 1.Chute 4 upper surface is provided with measured value pointer 9, and the position of measured value pointer 9 is the center of adjustable reference column 5.Supporting plate 2 assume responsibility for the function of ruler simultaneously, after adjustable reference column 5 is fixing, can read the numerical value of centre distance at supporting plate 2 at once, simple, convenient, fast.
Preferably, the hypomere end of stationary positioned post 1 and adjustable reference column 5 is conical, when reference column and metering-orifice to be measured are assembled, and can self-centering.
In order to assemble, carry, adjustment is convenient, and can be threaded between stationary positioned post 1 with supporting plate 2, also can be welded and fixed or rivet.
For guaranteeing measuring accuracy, the cylinder of stationary positioned post 1 and adjustable reference column 5 and workpiece hole to be measured assemble after clearance control be 0.05-0.1mm.
