Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings.

A fixing tool for quick disassembly and assembly of solenoid valve, as shown in Fig. 1 to Fig. 7, includes a hollow casing 1, an arc-shaped claw 2 and a driving mechanism, a fixed ring column 11 is installed at the bottom of the casing 1, and the casing 1 A cover 12 is fixed at the top, and a positioning hole 13 is opened in the center of the cover 12 to facilitate the approximate positioning of the solenoid valve or other cylindrical workpiece to be fixed. The evenly distributed guide rail grooves 14 of the holes 13 play a guiding role for the arc-shaped claw 2; The slider 22 of the upper part of the arc-shaped fixed piece 21 is fixed on the end of the slider 22 close to the positioning hole 13 , and a slot 211 is formed on at least one side of the top of the arc-shaped fixed piece 21 . The bottom surface of 22 is provided with first teeth 221; when there is a protrusion on one side of the solenoid valve or other cylindrical workpiece, placing the protrusion into the groove 211 can improve the fixing effect; the driving mechanism, the driving mechanism includes a fixed The first bevel gear 3 , the second bevel gear 4 and the drive plate 5 for driving the arc-shaped claw 2 in the casing 1 , the first bevel gear 3 is movably sleeved on the fixed ring column 11 , the second bevel gear 4 meshes with the first bevel gear 3, and the central axis of the first bevel gear 3 and the second bevel gear 4 is perpendicular, and the drive plate 5 is fixed on the first bevel gear 3. The top end of a bevel gear 3 is movably sleeved on the fixed ring column 11 , and the upper end surface of the drive plate 5 is provided with second teeth 51 . 221 is in an arc shape adapted to the second teeth 51, and the first teeth 221 mesh with the second teeth 51; The linkage between the second teeth 51 and the first teeth 221 drives the arc-shaped claw 2 to move along the guide rail groove 14. It should be noted that in actual production, the width of the slider 22 is small, and the spiral-shaped second teeth The number of turns of 51 on the driving disk 5 is also small, and in the case of a short arc length, its radian change is very small, and it can be in contact with the first teeth 221 on the slider 22 within the distance that the driving slider 22 moves back and forth. Adaptation; a connecting shaft 6 for driving the second bevel gear 4 to rotate is inherent on the second bevel gear 4, one end of the connecting shaft 6 is fixed on the second bevel gear 4, and the other end is The outer casing 1 passes through.

In this embodiment, a support bearing 112 for supporting the first bevel gear 3 is fixed on the side wall of the fixed ring column 11 , and the support bearing 112 is connected to the fixed ring column 11 by interference.

In this embodiment, a crank handle 61 for rotating the connection shaft 6 is fixed at the end of the connecting shaft 6 away from the second bevel gear 4 , so that the connecting shaft 61 can be rotated by rotating the crank handle 61 , so that the When the drive plate 5 rotates, the setting of the crank handle 61 can save labor when rotating the connecting shaft 6 .

In this embodiment, a fixing plate 7 is installed at the bottom end of the casing 1, and the fixing plate 7 is provided with a screw hole 71. By fixing the fixing plate 7 on the workbench, the fixing of the fixing tool can be realized, preventing the It moves and tilts while working.
