Description

Technical Field

[0001] This utility model relates to the field of casting repair, and in particular to a heating device for repairing defects in castings. Background Technology

[0002] A search of Chinese patents revealed publication number CN218735058U, entitled "A Fully Automatic Medium-Frequency Induction Heating Device." Addressing the cumbersome operation of existing fully automatic medium-frequency induction heating devices that rely on casters for movement, this invention proposes the following solution: The device includes a fully automatic medium-frequency induction heating device with a housing fixedly mounted at its bottom. Symmetrically arranged fixed wheels are fixedly mounted on the left side of the bottom of the housing. In this invention, pressing down on the control frame positions the two rotating columns. Pressing down on the positioning frame engages with the positioning plate, thus positioning the rotating wheels. This prevents the fully automatic medium-frequency induction heating device from turning via the rotating columns and from moving via the wheels, effectively positioning the device. Unlocking can also be performed simultaneously.

[0003] Existing heating devices cannot protect the heating coils, which are generally exposed and easily damaged by impacts from external objects when not in use, affecting their operation. Replacing the heating coils is also inconvenient, as they are usually fixed with bolts, requiring tools for disassembly and reassembly, which is cumbersome, increases workload, and reduces replacement efficiency. To solve these problems, we propose a heating device for repairing defects in castings. Utility Model Content

[0006] By adopting the above technical solution, the rotation of the motor drives the first bevel gear, which in turn drives the transmission shaft to rotate the second bevel gear. The rotation of the second bevel gear causes the screw to move the slider, and the movement of the slider causes the fixed seat to move the heating coil into the protective shell for protection. This method can achieve the purpose of protecting the heating coil, ensuring the safety of the heating coil, and improving its service life.

[0007] The present invention is further configured as follows: a conductive rod is bolted to the inner wall of the fixed base, a fixed cylinder is bolted to the surface of the fixed base, a heating coil is slidably sleeved on the inner wall of the fixed cylinder, and both ends of the heating coil are inserted into the inner wall of the conductive rod, a sliding cylinder is slidably sleeved on the surface of the fixed cylinder, a first spring is sleeved on the surface of the fixed cylinder, a triangular groove is formed on the inner wall of the sliding cylinder, a snap-fit ​​rod is slidably connected to the inner wall of the triangular groove, a second spring is sleeved on the surface of the snap-fit ​​rod, a snap-fit ​​groove is formed on the surface of the heating coil, and the snap-fit ​​groove snaps into one end of the snap-fit ​​rod.

[0008] By adopting the above technical solution, the sliding cylinder is moved by moving the toggle lever, which in turn moves the triangular groove. The movement of the triangular groove causes the locking rod to disengage from the locking groove under the action of the second spring, allowing the heating coil to be removed from the fixing cylinder for replacement. This method facilitates the replacement of the heating coil, reduces workload, and improves replacement efficiency.

[0009] The present invention is further configured such that: a protective shell is bolted to the surface of the protective shell, and the motor is located inside the protective shell.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model achieves the purpose of protecting the heating coil by means of a motor rotating to drive the first bevel gear, which in turn drives the transmission shaft to drive the second bevel gear to rotate. The rotation of the second bevel gear causes the screw to drive the slider to move. The movement of the slider causes the fixed seat to move the heating coil into the protective shell for protection. This ensures the safety of the heating coil and improves its service life.

[0023] 2. This utility model uses a movable lever to move the slide cylinder, which in turn moves the triangular groove. The movement of the triangular groove causes the locking rod to disengage from the locking groove under the action of the second spring, allowing the heating coil to be removed from the fixing cylinder for replacement. This method facilitates the replacement of the heating coil, reduces workload, and improves replacement efficiency. Attached Figure Description
