Spanner mounting fixture
Technical Field
The utility model relates to the technical field of aviation manufacturing and maintenance, in particular to a spanner fixing clamp.
Background
The aircraft often needs to use the spanner in the in-process of maintenance, because the both ends of spanner keep in touch with each other by middle rectangular shape handle, consequently if need with the fastener such as nut or bolt of keeping silent the centre gripping unscrew in the use, need constantly rotate the angle of spanner, but the spanner needs great space in rotatory in-process, and this space size is to guarantee that the size and the rotation angle of spanner can satisfy the operation requirement, still has sufficient space for operating personnel's hand in addition in order to operate. However, in practical work, due to the limitation of the space position of the installation of part of the accessories, after the spanner clamps the fastener, the operator cannot hold the handle of the spanner by hand, and meanwhile, due to the fact that the fastener is fixed tightly, the length of the handle of the spanner is short, and the torque is insufficient to loosen the fastener. It is therefore necessary to make a tool that assists the wrench in breaking down fasteners in small spaces.
Disclosure of utility model
In order to solve the problems, the utility model provides a wrench fixing clamp, which can assist a wrench to rotate in a small space after the wrench clamps a fastener on the basis of ensuring the structural strength of a tool, has the effect of increasing the torque of the wrench, and further improves the disassembly operation efficiency.
The technical scheme of the utility model is as follows:
The wrench fixing clamp comprises a clamping groove A, a clamping groove B, an adapter plate and a rotary joint, wherein the clamping groove A and the clamping groove B are located at two ends of the adapter plate and are symmetrically structured, but opposite in direction, the notches are opposite and face inwards, and the rotary joint is fixed at the center of the adapter plate.
The thickness of the adapter plate is 6mm, and the joint of the adapter plate and the clamping groove A and the clamping groove B is in a plane butt joint mode.
The angle of the clamping groove A and the clamping groove B is 6mm, the included angle is 15 degrees, the thickness of the material is uniformly reduced from the angle of the clamping groove A to the tail end of the clamping groove A and from the angle of the clamping groove B to the tail end of the clamping groove B, and the thickness f at the tail end is 4mm.
The rotary joint is of a hexahedral structure, the diameter of a hexagonal circumscribing circle with a regular cross section of the hexahedron is 25mm, a regular quadrilateral through hole is formed in the hexahedron, the side length of the quadrilateral is 15mm, a through hole is formed in the position corresponding to the adapter plate, and after the rotary joint is connected with the adapter plate, the two through holes are communicated.
The adapter plate is of a rectangular structure.
The utility model has the beneficial effects that the integrated structure design is adopted, the use is convenient, the size of the clamping groove can be suitable for most wrenches, the structure is simple, the weight is light, the deformation is not easy under the condition of applying large torque, and the clamping groove can be used under the working condition of small space.

Detailed Description
The following detailed description of the utility model is further illustrated in conjunction with the examples and the accompanying drawings, but is not intended to limit the utility model.
The embodiment provides a wrench fixing clamp, as shown in fig. 1-6, comprising a clamping groove A1, a clamping groove B2, an adapter plate 3 and a rotary joint 4. The four parts are of an integrated structure, and the clamping groove A1 and the clamping groove B2 are positioned at two ends of the adapter plate and are of a symmetrical structure but opposite in direction. The adapter plate 3 is of a rectangular structure, and the symmetrical center is connected with the rotary joint 4.
Further, according to the actual use condition of the tool, in order to ensure the stability and torque requirements of the clamping groove A1 and the clamping groove B2 in the process of clamping the wrench, the thickness d of the adapter plate 3 is set to be 6mm, and the joint of the adapter plate 3 and the clamping groove A2 (the clamping groove B2) is in a plane butt joint mode. The bent angle diameter e of the holding groove a (holding groove B2) was set to 6mm, and the included angle α was set to 15 °. The thickness of the material uniformly decreases from the bent corner of the holding groove A1 (holding groove B2) to the end of the holding groove A1 (holding groove B2). At the end, the thickness f of the holding groove A1 (holding groove B2) was set to 4mm. The appearance of rotary joint is hexahedron structure, and hexahedron regular cross section hexagon circumscribed circle's diameter g sets up to 25mm, and the hexahedron is inside to have a regular quadrilateral through-hole, and quadrilateral side length h sets up to 15mm. The corresponding position of the adapter plate is also provided with a through hole, and after the rotary joint is connected with the adapter plate, the two through holes are communicated.
In actual work, when an operator cannot directly rotate the wrench handle in the operation space, the wrench can be clamped on the wrench fixing clamp, then the wrench is connected with the rotary joint 4 through the stressing rod (shown in fig. 8), and torque is transmitted to the wrench clamped on the wrench fixing clamp through the rotating stressing rod to complete the operation, as shown in fig. 7. The spanner can be clamped on the rotary joint through the other spanner after the spanner is clamped by the spanner fixing clamp, so that the operation is completed.
