Problems solved by technology
[0004] However, the above patents have the following problems: when the circuit board needs to be spot-welded, it is necessary to turn the turntable first, and then press the switch of the electromagnet and the switch of the welding torch. The operation process is cumbersome and the processing efficiency is low.

Embodiment Construction
[0018] The present invention will be described in further detail below by means of specific embodiments:
[0019] The reference signs in the drawings of the description include: frame 1, sleeve 2, electromagnet 3, slider 4, first spring 5, rotating block 6, pressing block 7, limit plate 8, second spring 9, rotating Table 10, dial 11, fixed block 12, first switch 13, third spring 14, dividing plate 15, welding torch 16, second switch 17, fourth spring 18, first gap 19, blowpipe 20.
[0020] Such as figure 1 As shown, the TV inspection and maintenance device includes a frame 1, a sleeve 2 is welded vertically downward on the top of the frame 1, an electromagnet 3 is welded on the inner wall of the upper end of the sleeve 2, and a slider 4 is slidably connected to the inside of the sleeve 2. The magnetism of the slider 4 is opposite to that of the electromagnet 3. A first spring 5 is welded between the slider 4 and the electromagnet 3. The lower end surfaces on both sides of the...

The invention belongs to the field of fixing or positioning devices used for workpieces, and particularly relates to a television inspection and maintenance device. The television inspection and maintenance device comprises a machine frame, wherein the machine frame is rotationally connected with a rotating platform and provided with a sleeve; an electromagnet, a sliding block, a limit plate and apress block are sequentially arranged in the sleeve from top to bottom; the sliding block, the limit plate and the press block are all in sliding connection with the interior of the sleeve, the electromagnet is fixedly arranged in the sleeve, and one end of the limit plate stretches out of the sleeve; a first sliding groove is formed in the rotating platform, a fixed block and a first switch arefixedly arranged in the first sliding groove, and the interior of the first sliding groove is in sliding connection with a poking plate; notches are formed in the sleeve, the interiors of the notchesare rotationally connected with rotating blocks; and a second sliding groove is further formed in the machine frame, a second switch is fixedly arranged in the second sliding groove, the interior of the second sliding groove is in sliding connection with a welding gun, and the end, stretching out of the sleeve, of the limit plate abuts against the welding gun. By adopting the television inspectionand maintenance device, the steps of spot welding can be simplified, and the machining efficiency is improved.
Description
technical field [0001] The invention belongs to the field of fixing or positioning devices for workpieces, and in particular relates to a TV inspection and maintenance device. Background technique [0002] In the process of repairing home appliances, there are often many faults on the circuit board. The circuit board needs to be disassembled and repaired according to the damaged area. When the circuit board is repaired, the circuit needs to be connected by spot welding. During the spot welding process of the circuit board, it is necessary to The circuit board is constantly moved, but the circuit board needs to be fixed during spot welding, so as to avoid its movement and cause the spot welding position to shift and affect the maintenance effect. [0003] For this reason, Chinese patent CN107363449A discloses a kind of home appliance circuit board spot welding fixing device, comprises base, column, crossbeam and placing table; A vertically downward sleeve is fixed on the top...
