Description

Technical Field

[0001] The utility model relates to the technical field of transformer processing tooling, in particular to a special machine for surface treatment of transformer connection terminals. Background Art

[0002] During the casting process of the transformer, some transformer terminals are easily scratched or the resin part is too rough, which affects the appearance and performance of the transformer. Because the roughness of the terminal part does not meet the required accuracy of the product, it is necessary for the fitter to perform subsequent grinding and polishing to meet the design and use requirements of the transformer. The commonly used polishing method currently requires manual fixation or vise fixation of the transformer, and the use of electric tools to manually treat the surface of the transformer terminal. The transformer is prone to polishing and clamping defects, and the polishing efficiency is low. It cannot meet the fast, efficient, and safe grinding and polishing of the terminal and its associated resin part, which ultimately results in unqualified products, waste of manpower and financial resources, low production efficiency, and even more likely to cause danger to the polishing personnel during processing. Summary of the invention

[0003] The utility model is an improvement made in view of at least one defect of the prior art. It provides a special machine for surface treatment of transformer terminals, which grinds and polishes the transformer terminals and their associated resin parts after casting, solves the problems of clamping, polishing roughness and processing accuracy in the polishing process of the cast transformer terminals and their associated resin parts, reduces the danger to polishers during processing, shortens the polishing time of the terminals and their associated resin parts, and improves the efficiency of the overall grinding and polishing of the transformer terminals.

Slideways are fixedly installed on both sides of the left half of the base. The slideways have long through holes in the horizontal direction. Screws penetrating the through holes are evenly distributed on the upper parts of the long through holes. The slideways are plug-in connected with fixed top blocks. One end of the horizontal plate of the fixed top block is inserted into the long through holes and positioned by screws. The vertical plates of the fixed top blocks on both sides clamp the transformer on the base. A slide groove is provided in the middle of the right half of the base. A tailstock is installed on the slide groove. The tailstock can move along the slide groove direction and is fixedly connected with the base through bolts. A pin is provided at the front end of the tailstock, and the pin is pressed against the terminal end of the transformer.

A sliding block is inserted in the long slot hole, and the upper end of the sliding block is connected to a right-angle elbow, and a dividing plate is installed on the upper end of the right-angle elbow. The upper end of the dividing plate is connected to the grinding component mounting plate through a straight rod, and a handle is installed at one end of the grinding component mounting plate. A driven wheel, a driving wheel and a tensioning wheel are arranged non-linearly on the grinding component mounting plate, and a sandpaper belt is wound around the three wheels. The sandpaper belt is tensioned by the tensioning wheel, and the driving wheel is connected to the motor spindle.

[0005] Preferably, the sandpaper belt is a replaceable accessory, and a sandpaper belt with a suitable roughness is selected according to the product polishing requirements.

[0006] Preferably, the grinding assembly mounting plate and the driven wheel, driving wheel and tensioning wheel thereon are driven by the straight rod to rotate at the same angle through the rotation of the dividing plate to adjust the angle of the sandpaper belt to achieve the grinding of the taper terminal.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0015] like Figures 1 to 4 As shown, a special machine for surface treatment of transformer terminals is provided. The base 1 is a rectangular working platform. Slideways 3 are fixedly installed on both sides of the left half of the base 1. The slideways 3 have horizontal long through holes. Screws penetrating the through holes are evenly distributed on the upper part of the long through holes. The slideways 3 are plug-in connected with the fixed top block 5. One end of the horizontal plate of the fixed top block 5 is inserted into the long through hole and positioned by screws. The vertical plates of the fixed top blocks 5 on both sides clamp and fix the transformer 6 on the base 1. A slide groove is provided in the middle of the right half of the base 1. A tailstock 12 is installed on the slide groove. The tailstock 12 can move along the slide groove direction and is fixedly connected to the base 1 by bolts. A thimble is provided at the front end of the tailstock 12. The thimble is pressed against the end of the terminal 15 of the transformer 6. One side of the right half of the base 1 is fixedly connected to the sliding track groove 7. The sliding track The slot 7 has a vertical long slot hole, in which a sliding block 11 is inserted, the upper end of the sliding block 11 is connected to a right-angle elbow 9, the upper end of the right-angle elbow 9 is installed with a dividing plate 10, the upper end of the dividing plate 10 is connected to a grinding assembly mounting plate 17 through a straight rod, a handle 13 is installed at one end of the grinding assembly mounting plate 17, two driven wheels 2, a driving wheel 8 and a tensioning wheel 16 are arranged non-linearly on the grinding assembly mounting plate 17, the driven wheel 2, the driving wheel 8 and the tensioning wheel 16 are wound around the driven wheel 2, the driving wheel 8 and the tensioning wheel 16 in sequence, the sandpaper belt 4 is tensioned by the tensioning wheel 16, and the grinding assembly mounting plate 17 and the driven wheel 2, the driving wheel 8 and the tensioning wheel 16 thereon are driven by the straight rod to rotate the same angle through the rotation of the dividing plate 10 to adjust the angle of the sandpaper belt 4 to achieve the grinding of the taper terminal 15.

Then wrap the sandpaper belt 4 around the driving wheel 8, the driven wheel 2 and the tensioning wheel 16. Because the arrangement of the wheels is not linear, the sandpaper belt 4 will form a certain angle after passing through several wheels. Through the tensioning effect of the tensioning wheel 16, the sandpaper belt 4 is tightened to meet the use requirements. Start the motor 14, the motor 14 rotates to drive the driving wheel 8 to rotate, so that the sandpaper belt 4 moves with the driving wheel.
