Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:

as shown in fig. 1 to 6, the invention discloses a welding workbench for a guide plate and a primary terminal, which comprises a base 1, a support panel 2 arranged on the base 1; two parallel transverse guide rails 3 are fixed on the supporting panel 2; the upper end of the transverse guide rail 3 is provided with a transverse moving platform 4; two parallel longitudinal guide rails 5 are fixed on the transverse moving platform 4; a longitudinal moving platform 6 is fixed at the upper end of the longitudinal guide rail 5; the longitudinal moving platform 6 is provided with a detachable horizontal connecting plate 7, and the upper end of the horizontal connecting plate 7 is provided with a cylinder support; the cylinder bracket comprises a vertical bracket 81 fixed with the longitudinal moving platform 6; a horizontal transverse bracket 82 is arranged at the top end of the vertical bracket 81; the transverse bracket 82 is provided with a through hole 82a matched with the telescopic rod of the cylinder; preferably, in order to improve the supporting strength, a reinforcing rib 83 connecting the vertical bracket 81 and the horizontal bracket 82 is further provided on the cylinder bracket.

Preferably, the vertical bracket 81 is fixed on the horizontal connecting plate 7 through a detachable vertical connecting plate 81 a; the bottom of the vertical connecting plate 81a is in threaded connection with the horizontal connecting plate 7; one side of the vertical connecting plate, which is far away from the welding part, is connected with the vertical bracket 81, and one side of the vertical connecting plate, which is close to the primary terminal 11, is in threaded connection with a dustpan-shaped welding supporting plate 9; the welding supporting plate 9 is arranged below the transverse support 82, and left and right edges of the welding supporting plate 9 are used for clamping and positioning the primary terminal 11.

Preferably, the welding supporting plate 9 is provided with a positioning block for positioning the primary terminal 11; the positioning block is in threaded connection with the welding supporting plate 9; the guide plate 12 is arranged right below the through hole 82a, and the central axis of the through hole 82a is intersected with the central axis of the guide plate 12, so that the guide plate 12 is not biased. To press the guide plate 12 and the primary terminal 11 tightly, a cylinder is required to provide a vertical downward external force, so that the stroke of the cylinder needs to move up and down; the minimum stroke of the cylinder is determined according to the vertical distance between the transverse bracket 82 and the upper surface of the red copper guide plate 12, and then the type of the cylinder is determined.

Preferably, the structures of the transverse guide rail 3 and the longitudinal guide rail 5 are the prior art, and are not described herein again, and in order to prevent the moving platform from moving out of the guide rails, the limiting blocks 13 may be welded at the two ends of the transverse guide rail 3 and the longitudinal guide rail 5.

Preferably, the welding supporting plate 9 and the positioning block are designed according to the size of the primary terminal 11, and the welding supporting plate 9 and the positioning block are positioned in a way that the position of the primary terminal 11 can be matched with a heating coil 14 of the high-frequency welding machine. Because the primary terminal 11 frequently used by the current transformer has two thickness specifications of 25mm and 35mm, a first positioning block 10a matched with the primary terminal 11 with the thickness of 35mm is arranged on the inner side of the welding supporting plate 9; the upper end of the welding supporting plate 9 is provided with a second positioning block 10b matched with the primary terminal 11 with the thickness of 25 mm; after the primary terminal 11 is fixed by the welding supporting plate 9 and the positioning block, the operator vertically places the guide plate 12 on the upper surface of the primary terminal 11.

The position of the heating coil 14 of the high-frequency welding machine is fixed and cannot be adjusted, so that the height of a welding workbench and the transverse and longitudinal adjusting strokes of the welding workbench need to be determined in advance during use. The transverse moving platform 4 and the longitudinal moving platform 6 are adjusted through the stroke, so that the workpiece to be welded reaches the position of the heating coil 14, the electromagnetic valve control switch is started, the air cylinder works, and the guide plate 12 and the primary terminal 11 are pneumatically clamped. Then, the high frequency welder is turned on, and the heating coil 14 is operated to weld the primary terminal 11 and the guide plate 12 together. After welding, the position of the welding workbench is adjusted to be away from the heating coil 14, the weldment is taken out for standby after water cooling, and the next welding is continued.

The welding workbench of the invention uses the high-frequency welding machine to replace a gas welding process, the welding workbench can be freely adjusted and pneumatically clamped, the work which needs to be finished by two persons originally can be finished by only one person, the labor is saved, the welding efficiency and quality are improved, waste gas polluting air is not generated, and the welding workbench is safer and more environment-friendly.

The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
