Different limit blocks are replaced to adapt to different rotating shaft workpieces to improve the versatility of the device.

Preferably, a pointing protrusion is provided on the back of the body corresponding to the positioning groove of the turntable, and the pointing protrusion is interposed between the two limiting blocks. The pointing protrusion guides the PIN needle of the rotating shaft workpiece, and when the PIN needle is positioned on the pointing protrusion, the rotating shaft workpiece can just be inserted into the turntable workpiece. The setting of the pointing protrusion facilitates the installation of the rotating shaft workpiece to improve work efficiency.

Preferably, the bottom of the wire module positioning groove is provided with several wire module locking holes. The locking hole of the steel wire module prevents the workpiece of the steel wire module from protruding outward when the body is turned over.

Preferably, two sides of the body corresponding to the positioning grooves of the steel wire module are respectively provided with body installation holes. It is convenient to expand the function of the ontology. For example: It is fixedly connected with the quality inspection device, and can perform quality inspection on the welding of the endoscope turntable.

Preferably, the two sides of the body corresponding to the location of the welding notch have an arc-shaped structure matching the contour of the workpiece on the turntable. Eliminate the interference of the body on both sides of the welding gap on the welding of the turntable workpiece.

Preferably, the whole body is composed of a narrow part and a wide part in a convex shape, the turntable positioning groove is located at the narrow part, and the steel wire module is located at the wide part. The embossed structure facilitates welding operations on the turntable workpiece and wire winding on the turntable workpiece.

Preferably, each corner of the body has a circular arc corner structure. Avoid corners that cause personal injury to people.

Beneficial effect

Limit the rotation of the rotating shaft workpiece to limit the rotation of the turntable workpiece, which is convenient for winding the steel wire on the turntable workpiece and the steel wire module workpiece; restricting the direction of the rotating shaft workpiece makes the welding area of the turntable workpiece communicate with the welding gap, expands the operating space during welding, and improves welding Efficiency and welding quality; the rotation of rotating shafts of different sizes is limited by different limit blocks to improve the versatility of the device; the steel wire module is threaded through the steel wire module and the limit hole of the steel wire module through screws to avoid the steel wire module when installing the rotating shaft. Outer protruding; through the arc hole, the limit block rotates around the axis of the limit hole of the rotating shaft to clamp the PIN pin, limiting the rotation of the rotating shaft; avoiding personal injury caused by the corner and improving safety; the body presents a convex structure, improving work efficiency.
