Detailed Description

The utility model will be further described with reference to the accompanying drawings, but the scope of the utility model is not limited to the following.

As shown in fig. 1 to 5, the swash plate assembly measuring jig includes a standard column 5, a connecting sleeve 6 and a measuring gauge 1; wherein, one end face of the marking post 5 is an inclined plane which is matched with the angle of the inclined disc, the other end is sleeved with a connecting sleeve 6 in a sliding way, and the connecting sleeve 6 is fixed on a fixed frame (the fixed frame is not shown); the measuring instrument 1 is arranged on the connecting sleeve 6 through the instrument frame 2, and a measuring head of the measuring instrument 1 is abutted against the standard column 5.

The connecting sleeve 6 is fixed and is fitted over the axially movable standard column 5, the inclination of the standard column 5 resting against the tilting plate and the other end resting against the measuring head of the measuring instrument 1. Because the elastic range of the swash plate is measured, when the standard column 5 is pressed down by force, the measuring heads of the measuring table 1 synchronously act, and the measurement can be finished.

In the scheme, in order to facilitate the pressing action of the standard column 5, an extrusion structure formed by the door-shaped frame seat 4, the cam 7 and the handle 3 is designed. In the squeezing structure, the door-shaped frame seat 4 is arranged across the end surface of the connecting sleeve 6, a cam 7 is rotationally arranged on the door-shaped frame seat, the cam 7 is provided with the integrated handle 3, and the cam 7 abuts against the end surface of the standard column 5.

The working principle of the extrusion structure is that the cam 7 is rotated by the handle 3, and the cam 7 can generate extrusion force on the end surface of the standard column 5 when rotating, so that the standard column 5 can be pressed down.

Optionally, the swash plate assembly measuring clamps are symmetrically arranged on two sides of the measuring head of the measuring meter 1, and the number of the cams 7 is two; the handles 3 corresponding to the two cams 7 are simultaneously moved inward or outward.

Since the cam 7 does not apply a force at the center position of the end face of the standard post 5, the force may be separated in both the radial direction and the axial direction, and the separation in the radial direction may cause the standard post 5 to be slightly displaced in the radial direction, resulting in an inaccurate measurement result. And the structure that the two cams 7 are symmetrically arranged can offset the component force in the radial direction, thereby improving the measurement result.

Optionally, the two ends of the connecting sleeve 6 of the measuring clamp of the swash plate assembly are respectively provided with an integrated flange A8 and a flange B9, the flange A8 is close to the swash plate, and the flange A8 is installed on the fixed frame. The number of the door-shaped frame seats 4 is two, the two are parallel at intervals and are vertically positioned on the end surface of the flange plate B9, and the cam 7 can be rotatably arranged between the two door-shaped frame seats 4 through the rotating shaft 10.

Preferably, the rotating shaft 10 is in the shape of a bolt rod, and one end of the rotating shaft, which is far away from the cap, is provided with a thread, and the threaded end extends out of the door-shaped frame seat 4 and then is locked by a nut, so that the structure for locking the angular position of the cam 7 is formed. When the handle 3 drives the cam 7 to rotate together to perform measurement reading, the handle 3 needs to maintain the position, otherwise, the cam 7 may act together, thereby affecting the measurement accuracy; however, after the rotating shaft 10 is locked to the door frame 4 by the nut, a person can be separated from the handle 3, thereby facilitating reading.

In this embodiment, as shown in fig. 2: the lower end of the watch frame 2 is fixed on the flange B9 in a threaded manner, and the watch frame 2 is provided with a structure for adjusting the axial position and the radial position of the measuring head.

In this embodiment, as shown in fig. 1 and 5, the standard column includes a column a11, a column B12, and a column C13 that are coaxially connected in sequence, diameters of the three are sequentially reduced, a tapered mesa is formed between the column a11 and the column B12, and a step surface is formed between the column B12 and the column C13; the end surface of the column A11 is an inclined surface, the connecting sleeve 6 is fittingly sleeved on the column B12, and the cam 7 abuts against the stepped surface between the column B12 and the column C13; the column C13 extends from the door frame 4 and contacts the measuring head of the measuring device 1.

In this embodiment, the cylindrical surface of the connecting sleeve 6 is provided with an observation window, and the flange A8 has a chamfer adapted to the tapered surface between the post A11 and the post B12.

The above examples only represent preferred embodiments, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
