[0034] REFERENCE Figure 1 A cylinder body position degree gauge, comprising a bottom plate 11, a reference seat 12, a cushion block 31 and a measuring seat 51. The reference seat 12, the cushion block 31 and the measuring seat 51 are all installed on the bottom plate 11, and the measuring seat 51 is located between the reference seat 12 and the cushion block 31.

[0035] The reference seat 12 is provided with a reference block 13, the reference block 13 is provided with a reference surface 14 close to one side of the measuring seat 51, the reference block 13 is provided with a fixed positioning pin 15 at the reference surface 14, and the reference surface 14 is vertically arranged. If the reference surface 14 is horizontally arranged, the operator needs to bend down to adjust the line of sight to the same height of the reference surface 14 to observe whether the workpiece is in close contact with the reference surface 14, and the operation is relatively inconvenient. The reference surface 14 is vertically arranged, the workpiece and the reference surface 14 can be observed on the vertical surface parallel to the reference surface 14, and the function of observing whether the workpiece is accurately positioned is realized. The reference seat 12 is slidably connected with a first cylinder hole detection column 21, and the reference block 13 is provided with a first through hole 22 for the first cylinder hole detection column 21 to pass through. The first cylinder hole detection column 21 is slid on the reference seat 12, and the first cylinder hole detection column 21 is inserted into the cylinder workpiece to realize the function of detecting the cylinder workpiece through the first cylinder hole detection column 21. The reference seat 12 is slidably connected with a second cylinder hole detection column 23, the reference block 13 is provided with a second through hole 24 for the second cylinder hole detection column 23 to pass through, the first cylinder hole detection column 21 is located at the center position of the reference block 13, and the second cylinder hole detection column 23 is arranged in a staggered manner with the first cylinder hole detection column 21. The second cylinder hole detection column 23 is slid on the reference seat 12, and the second cylinder hole detection column 23 is inserted into the cylinder workpiece to realize the function of detecting the cylinder workpiece through the second cylinder hole detection column 23. The reference block 13 is provided with a plurality of screws 16, and the plurality of screws 16 and the second cylinder hole detection column 23 are uniformly distributed around the first cylinder hole detection column 21. The second cylinder hole detection column 23 and the plurality of screws 16 provide support force for the reference block 13, so that the reference block 13 remains stable and the stability of the reference block 13 is improved.

The linkage plate 44 is provided with a bending section 45. When the pressing block 35 presses the workpiece and exerts a pre-tightening force on the workpiece, a reaction force generated by the pressing block 35 is applied to the linkage plate 44 through the quick clamp rod 34, so that the bending section 45 on the linkage plate 44 is elastically deformed, thereby the pressing block 35 is kept in a state of pressing the workpiece through the elastic force of the bending section 45.

The two linkage plates 44 are located on both sides of the handle 43, thereby improving the stability between the handle 43 and the linkage plate 44. The spacing between the two bending sections 45 is greater than the thickness of the support plate 41. When the rotating plate 42 is rotated to the side away from the datum block 13, the support plate 41 can enter between the two bending sections 45 because the spacing between the two bending sections 45 is greater than the thickness of the support plate 41, thereby preventing the linkage plate 44 from being clamped by the support plate 42 when the rotating plate 42 is rotated to the side away from the datum block 13.

[0039] ①, rough boring is performed on the first cylinder hole and the second cylinder hole on the cylinder workpiece.

[0040] ②, the valve plate surface and each positioning hole and detection hole of the cylinder workpiece are processed according to the drawing.

[0046] 8. At the same time, two first cylinder hole detection columns 21 and detection pins 53 are inserted to detect the position of the workpiece detection hole of the rear cylinder relative to the reference surface 14, and if it is smooth, it is considered to be qualified, otherwise it is not qualified.

[0047] When different workpieces need to be positioned, the detection pin 53 can be removed and replaced with a detection pin 53 of different size, so that different workpieces can be detected, and the detection needs of different workpieces can be met.

[0049] By pushing the handle 43 to drive the rotating plate 42 to rotate, the rotating plate 42 drives the quick clamping rod 34 and the pressing block 35 to press the workpiece on the reference block 13 through the linkage plate 44, realizing the function of clamping the workpiece. Without repeatedly rotating the mechanism, the workpiece can be clamped, which is convenient for operation and has the advantage of high detection efficiency.

[0050] When the pressing block 35 presses the workpiece, the rotating plate 42 rotates to a position close to the measuring seat 51, at which time the friction between the rotating plate 42 and the linkage plate 44 can realize self-locking of the mechanism, so as to maintain the state that the pressing block 35 presses the workpiece, which is convenient for the operator to operate the measuring mechanism.

[0051] The pressing block 35 is rotated on the quick clamping rod 34, so that the pressing block 35 screw-connected with the quick clamping rod 34 moves on the quick clamping rod 34, thereby adjusting the position of the pressing block 35 on the quick clamping rod 34.
