Abstract
The utility model discloses a concentricity measuring tool for a brake pump of an automobile. The concentricity measuring tool is characterized by mainly consisting of a clamp body, a measuring stick and a planeness meter, wherein one end of the clamp body is provided with a screw rod which is outward extended; the middle of the screw rod is penetrated through a through hole; one end of the clamp body is a clamping mechanism; the planeness meter is clamped in the clamping mechanism; the measuring stick is a T-shaped body and consists of a measuring rod and a flange plate, where in the middle of the flange plate is fixedly connected with the end of the measuring rod; a gap of the measuring rod is penetrated through the through hole in the middle of the screw rod; and the outer plane of the flange plate is resisted with the head of the planeness meter. As the concentricity measuring tool consists of the clamp body, the measuring stick and the planeness meter, when the concentricity measuring tool is in use, the measuring stick is rotated at a circle on the conical surface of an oil hole and an air hole, and the indication of the planeness meter is read, so that the concentricity measuring tool can measure the concentricity value of the oil hole and the air hole, and is exact and convenient.
Description
Technical field
The utility model relates to a kind of test measuring device, particularly relates to a kind of automobile brake pump concentricity test measuring device.
Background technology
The concentricity of the oilhole pore of automobile brake pump is the project of an emphasis management and control, and because of it directly has influence on the sealing of brake system, if the bad entrucking of concentricity connects tubing sub and can't seal, system can't set up pressure.Shown in Figure 1A, Figure 1B, on master cylinder wheel cylinder 10, offer oilhole Ma1 and pore Ma2, the conical surface of Ma1 and pore Ma2 with screw thread top footpath be disposable machining, Gu Luowending footpath and the concentricity in footpath, the end directly have influence on the fitted seal of oilhole Ma1 and pore Ma2 and tubing sub or bleed screw.Formerly can't directly measure data, can only judge according to the vestige of pressing whether concentricity is qualified with gas screw or tubing sub locking.This kind detection method is science, erroneous judgement and big with the precision influence of screw of locking and oil pipe easily not.
The utility model content
The purpose of this utility model is to provide a kind of automobile brake pump concentricity test measuring device that can accurately, conveniently detect brake pump oilhole pore concentricity.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of automobile brake pump concentricity test measuring device; It mainly is made up of clamp body, test bar and plane kilsyth basalt; One end of described clamp body is provided with the screw rod that extends outward, and a through hole is run through at the middle part of this screw rod, is a clamping device at the other end of clamp body; Described plane kilsyth basalt is clamped in the clamping device; Described test bar is the T-shaped body, is fixed in the ring flange that detects rod end by test rod and middle part and constitutes, and the test rod gap is located in the through hole at screw rod middle part, and the ring flange outerplanar leans mutually with the gauge outfit of plane kilsyth basalt.
Described clamping device is made of clamping plate and screw, and clamping plate are provided with a holding tank, and offers an open slot that connects holding tank and outer wall, and be the boundary with the open slot, offer shoulder hole on the clamping plate of one side, the opposite side clamping plate are offered screw, and described screw passes shoulder hole, is screwed onto in the screw.
After adopting such scheme, because the utility model is made up of clamp body, test bar and plane kilsyth basalt, turns around on the conical surface of oilhole pore by test bar during detection, by reading the reading of plane kilsyth basalt, just can detect the concentricity value of oilhole, pore, accurately, conveniently.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment
As shown in Figure 2, the utility model is a kind of automobile brake pump concentricity test measuring device; It mainly is made up of clamp body 1, test bar 2 and plane kilsyth basalt 3.
With reference to shown in Figure 2, an end of described clamp body 1 is provided with the screw rod 11 that extends outward as Fig. 3 A, Fig. 3 B, and a through hole 12 is run through at the middle part of this screw rod 11.The other end at clamp body 1 is a clamping device, it is made of clamping plate 13 and screw 4, clamping plate 13 are provided with a holding tank 14, and offer an open slot 15 that connects holding tank 14 and outer wall, and be the boundary with open slot 15, offer shoulder hole 131 on the clamping plate 13 of one side, the opposite side clamping plate are offered screw 132.Described screw 4 passes shoulder hole 131, is screwed onto in the screw 132, and the plane kilsyth basalt 3 that inserts in the holding tank 14 is clamped.
With reference to shown in Figure 2, described test bar 2 is the T-shaped body as Fig. 4, and the ring flange 22 that is fixed in test rod 21 ends by test rod 21 and middle part constitutes.Test rod 21 gaps are located in the through hole 12 at screw rod 11 middle parts, and ring flange 22 outerplanars lean mutually with the gauge outfit of plane kilsyth basalt 3 in being set in holding tank 14.
During use, on the conical surface of oilhole Ma1 on the master cylinder wheel cylinder 10 (with reference to shown in Figure 1) and pore Ma2, turn around, can detect the concentricity value of oilhole Ma1 and pore Ma2 by test rod 21.
The above, it only is the utility model preferred embodiment, the version of clamp body can have various, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
