Description

Technical Field

[0001] The invention belongs to the technical field of wrenches, and in particular relates to a bidirectional rotating wrench device used for coaxial relative disassembly and assembly of two shafts. Background Art

[0002] Centrifuges are frequently used in the tobacco production process. One end of the centrifugal shaft in the centrifuge is coaxially and relatively fixedly connected to the output shaft of the drive motor to achieve power transmission. When installing or disassembling one end of the centrifugal shaft and the output shaft of the drive motor, the two shafts need to be rotated in opposite directions. Now two wrenches are generally used, one clamps the centrifugal shaft and the other clamps the motor output shaft. The operator holds the two wrenches in both hands and applies force in opposite directions to achieve the disassembly and assembly of the shafts. In this way, since the two wrenches are independent of each other, they are easy to fall off. In addition, the operating position of the equipment is relatively high, which will cause great inconvenience in operation. Therefore, it is necessary to propose improvements.

[0018] The bidirectional rotating wrench device for coaxially disassembling and assembling two shafts comprises a clamping wrench Ⅰ1 for clamping one of the two coaxially connected shafts and a clamping wrench Ⅱ2 for clamping the other shaft. Specifically, Figure 3 As shown, the structure of the clamping wrench I1 and the clamping wrench II2 is the same and includes a wrench handle 11 and an inverted L-shaped clamping piece 13. The upper end of the wrench handle 11 is provided with a transverse clamping piece 12 that constitutes a wrench jaw, and the transverse clamping piece 12 is provided with a wrench jaw adjustment hole 14. One end of the inverted L-shaped clamping piece 13 is provided with an external thread and a fixing nut 15 and a locking nut 16 are screwed on it after passing through the wrench jaw adjustment hole 14. The two inner surfaces of the inverted L-shaped clamping piece 13 and the front of the transverse clamping piece 12 constitute a jaw and are provided with an anti-slip elastic piece 17.

[0019] It also includes an intermediate slide member 3, and the clamping wrench Ⅰ1 and the clamping wrench Ⅱ2 are respectively connected to the upper and lower sides of the intermediate slide member 3 through connecting members that do not affect the rotation and direction adjustment of the two wrenches. Figure 1 The intermediate slide member 3 adopts an arc-shaped rod structure, as shown in FIG. Figure 2 As shown, the upper and lower surfaces of the intermediate slide member 3 are both provided with arc-shaped slide grooves 4, and the two ends of the intermediate slide member 3 are provided with slide limit structures 5.

[0020] When in use, for two coaxially connected shafts, use clamping wrench Ⅰ1 to clamp one of the shafts, and use clamping wrench Ⅱ2 to clamp the other shaft. During the clamping process, the distance between the two clamping wrenches Ⅰ1 and Ⅱ2 can be adjusted by the telescopic rod structure 6; during the relative rotation and disassembly of the two shafts by clamping wrench Ⅰ1 and clamping wrench Ⅱ2, the relative angle position between clamping wrench Ⅰ1 and clamping wrench Ⅱ2 can be adjusted by the slide structure between the middle slide member 3 and the corresponding clamping wrench through the two ends of the telescopic rod structure 6, and combined with the curved arc structure of the middle slide member 3, so that the two clamping wrenches will not interfere with each other during disassembly and rotation.
