Description

Technical Field

[0001] This utility model relates to the field of graphite electrode rod machining, specifically to a bracket for easy marking before machining graphite rods. Background Technology

[0002] The machining of electrodes (graphite rods) requires turning the outer wall to adjust the thickness. The graphite rod needs to be mounted on a lathe. During the process, the core of the graphite rod, that is, the center of the end face, is clamped in the center of the chuck. Therefore, it is necessary to find the center of the end face. Usually, the rectangle centering method is used. Specifically, draw horizontal lines on the end face, rotate the electrode, and draw a rectangle starting from the vertex of each line. Then draw the diagonals of the rectangle. The intersection of the two diagonals is the center. Therefore, a fixture bracket needs to be designed to place the graphite rod horizontally to assist in scribing. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-6As shown, a bracket for easy marking before machining graphite rods includes a long support plate 1 and a marking tool 2. The top of the long support plate 1 is provided with grooves 3 near both ends. Above each of the two grooves 3, there is an L-shaped bracket 4. The two sides of the bracket 4 are flush with the two sides of the long support plate 1, which can ensure that the top of the bracket 4 is horizontal and vertical with the long support plate 1. A bolt 5 passes through the groove 3, and the end of the bolt 5 abuts against the long support plate 1. The bolt 5 passes through the bottom of the bracket 4 and is screwed with a nut 6. The two brackets 4 are used to support the electrode. The brackets 4 can move in the groove 3 by the bolt 5, and the distance between the two brackets 4 can be adjusted to adapt to motors of different lengths. Tightening the nut 6 can lock the position of the bracket 4 on the long support plate 1.

[0020] The top of the bracket 4 is provided with a V-shaped notch 7, and below the V-shaped notch 7 are multiple pairs of through holes 8. Each pair of through holes 8 is arranged on the bracket 4 on both sides of the V-shaped notch 7. A roller 9 is rotatably mounted on any pair of through holes 8. Each pair of through holes 8 gradually rises along the V-shaped notch 7. If each pair of through holes 8 is equipped with a roller 9, the distance between each pair of rollers 9 gradually increases from low to high in order to accommodate electrodes of different thicknesses. The wheel surface of the roller 9 is higher than the V-shaped notch 7. The electrode is placed on the V-shaped notch 7 and contacts the wheel surface of the roller 9 so that the electrode can be rotated when scribing.

[0021] Support legs 10 are fixed at both ends of the bottom of the long strip support plate 1.

[0022] The drawing tool 2 includes a circular base 2.1, which is stepped in this embodiment. A support rod 2.2 is fixed on the top of the circular base 2.1. A stencil 2.3 with a pointed end is rotatably connected to the top of the support rod 2.2. The rotation of the support rod 2.2 and the stencil 2.3 is damped. The height of the stencil 2.3 can be adjusted by rotating it. The pointed end of the stencil 2.3 makes it easy to leave a mark when sliding on the electrode end face. When using the drawing tool 2, hold the drawing tool 2 by hand and move it along the top of the long support plate 1 to keep it horizontal, while simultaneously using the pointed end of the stencil 2.3 to etch a horizontal line on the electrode end face.

[0023] A horizontal rectangular slide bar 11 is fixed to the side of any end of the long support plate 1. A connecting rod is fixed between the rectangular slide bar 11 and the long support plate 1, leaving a gap. A horizontal sleeve 12 slides on the rectangular slide bar 11. A rectangular connecting rod 13 that is horizontal and perpendicular to the long support plate 1 is fixed to the side of the horizontal sleeve 12. A vertical sleeve 14 slides on the rectangular connecting rod 13. A rectangular vertical rod 15 is fixed to the top of the vertical sleeve 14. A vertical sleeve 16 slides on the rectangular vertical rod 15. A ruler 17 that is parallel to the long support plate 1 and horizontal and perpendicular is fixed on the vertical sleeve 16. The ruler 17 can also be called a straightedge. A wing bolt 18 is screwed onto the vertical sleeve 16.

[0024] The sliding of the horizontal sleeve 12 and the rectangular slide rod 11, and the sliding of the vertical sleeve 14 and the rectangular connecting rod 13 are both damped sliding. The horizontal sleeve 12 slides on the rectangular slide rod 11, adjusting the scale 17 to fit the electrode end face. The vertical sleeve 14 slides on the rectangular connecting rod 13, adjusting the scale 17 to be close to the electrode end face. The vertical sleeve 16 slides up and down on the rectangular vertical rod 15, adjusting the scale 17 to be at different heights on the electrode end face. The scale 17 can be used to easily draw straight lines on the electrode end face, improving operational accuracy.

[0025] Working principle: When using this utility model, the electrode is placed on the two V-shaped notches 7 and in contact with the wheel surface of the roller 9. Due to the friction of the electrode's own weight, it will not move axially. When drawing lines, hold the drawing tool 2 by hand and move it along the top of the long support plate 1, keeping it horizontal. At the same time, use the tip of the engraving plate 2.3 to engrave a horizontal line on the electrode end face. After drawing one line, rotate the electrode downwards and draw the next line until a rectangle appears. The ruler 17 can be used to assist in drawing the diagonal of the rectangle, and then find the intersection point as the center of the circle.

[0026] Advantages: The electrode is accommodated by the V-shaped notch 7 of the bracket 4, and the roller 9 facilitates the rotation of the electrode, so that the drawing tool 2 can be used to quickly draw lines on the electrode end face, which facilitates the application of the rectangle to circle method and improves the efficiency of subsequent electrode machining.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
