Description

Technical field:

[0001] The invention belongs to the technical field of tooling design and parts manufacturing, and in particular relates to a rotary locking device for turning a tire. Background technology:

[0002] As an important component of railway freight cars, the middle component of the lower cover plate of the bolster requires that after front-side welding, the workpiece needs to be flipped over and the root needs to be cleaned with a carbon arc gouging machine before reverse welding. During the processing of the middle component of the lower cover plate of the bolster, in order to reduce the labor intensity of the operator, a flipping tool is used for the flipping operation of the middle component of the lower cover plate of the bolster. In order to ensure the safety of the middle component of the lower cover plate of the bolster during the flipping process, the workpiece needs to be locked before flipping, then flipped, and then the back weld needs to be cleaned and welded. In the production process of the middle component of the lower cover plate of the bolster, the locking mechanism of the flip tire usually adopts a pneumatic locking mechanism, a hydraulic locking mechanism or a calliper locking mechanism. For this part, a pneumatic motor or a hydraulic locking mechanism is used to lock the workpiece. The flip tire has a complex structure, resulting in the designed flip tire occupying a large working area. The use of a calliper to lock the workpiece will affect the operator's welding operation and affect production efficiency. Summary of the invention:

[0003] In response to the above-mentioned problems, the present invention provides a rotary locking device for a flip tire, which is suitable for locking a workpiece with a circular hole during the flipping process, especially for locking the workpiece during the flipping process composed of the lower cover plate of the bolster.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0005] The present invention provides a rotary locking device for flipping a tire, which consists of a handle, a rotating screw, a rotating sleeve, a clamping pad and a locking pad; the handle is fixedly connected to one side of the rotating sleeve, the locking pad is fixedly installed on the flipping tire composed of a cover plate under the bolster, and the rotating screw is sequentially sleeved with a rotating sleeve, a clamping pad and a locking pad from top to bottom; the rotating screw consists of a handle, a screw and a locking round steel, the handle is arranged at the top of the screw, the rotating sleeve is sleeved on the screw, the clamping pad is sleeved at the lower end of the screw and below the rotating sleeve, the locking round steel is fixedly arranged at the lower end of the screw and below the clamping pad, the locking round steel passes through the screw and is arranged perpendicular to the screw; a special-shaped hole for the screw and the locking round steel to pass through is provided on the locking pad, and the outer circle of the special-shaped hole of the locking pad serves as the center positioning reference of the component in the cover plate under the bolster.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] 1. The present invention has a compact and flexible structure, simple operation, and can quickly lock the workpiece. The locking and unlocking operations can be achieved by manually rotating the handle and the handle, without the need for complex tools and equipment, thus reducing the difficulty of operation.

[0008] 2. The present invention has a double locking function, which can be quickly pre-tightened by the handle and then finally locked by rotating the handle. After pre-tightening and locking, the workpiece is safe and reliable during the flipping process.

[0009] 3. The present invention integrates positioning and locking. The outer circle of the special-shaped hole of the locking pad also has the positioning function, which simplifies the tooling structure and improves assembly consistency and efficiency.

[0010] 4. The present invention is used to lock the workpiece, and the turning tool occupies a smaller production area, and during the production process, it will not affect the welding process of the operator. Description of the drawings:
