Description

Technical Field

[0001] The invention relates to the technical field of electric heating tube processing, and in particular to a surface grinding device for electric heating tube processing. Background Art

[0002] The electric heating tube is an electrical component that converts electrical energy into thermal energy, mainly used for heating. It usually consists of a metal tube (such as stainless steel or copper) as the outer shell, with a spiral resistance wire inside, and magnesium oxide powder with good thermal conductivity and insulation filled in between. This design enables the electric heating tube to efficiently convert electrical energy into thermal energy for heating. There are many types of electric heating tubes, including metal heating tubes, crystal heating tubes, and nickel-gold heating tubes. Metal heating tubes use stainless steel or copper materials, which have high heating efficiency but are prone to scaling; crystal heating tubes are heated by carbon film, with poor heat transfer and low stability; nickel-gold heating tubes are made of nickel alloy, with extremely high heating efficiency and corrosion resistance, and are a more ideal type of heating tube. The core purpose of electric heating tube grinding is to improve the smoothness and uniformity of the electric heating tube surface, thereby improving heating efficiency and reducing breakage, which can be achieved by using a special grinding device.

[0003] At present, when the electric heating tube is being polished, the straight tube of the electric heating tube is placed in the cleaning box of the magnetic polishing machine. The magnetic polishing machine guides the abrasive through the magnetic field to polish the surface of the electric heating tube in the cleaning box, so that the surface of the electric heating tube has good smoothness and uniformity.

[0004] During the batch grinding and polishing process of the electric heating tubes in the magnetic polishing machine, the electric heating tubes are usually placed directly in the cleaning box of the magnetic polishing machine in batches, and then the abrasives grind the electric heating tubes under the action of magnetism. However, the electric heating tubes are easily collided with each other under the drive of the abrasives, resulting in collision and damage of the stud ends at both ends of the electric heating tubes. In addition, after grinding and polishing, the electric heating tubes and abrasives are often required to be poured into a screen frame to sieve off the abrasives to obtain the electric heating tubes, resulting in inconvenience in obtaining the materials after grinding and polishing the electric heating tubes. This makes it inconvenient to grind and polish the electric heating tubes at the magnetic polishing machine. For this reason, we propose a surface grinding device for electric heating tube processing. Summary of the invention

[0005] The main purpose of the present invention is to provide a surface grinding device for electric heating tube processing. The present invention arranges a holding tool at the cleaning box of the magnetic polishing machine body. After the pressure strip of the holding tool is lifted up and away from the support strip, the double-ended threaded column of the electric heating tube can be placed at the support strip. With the help of the pressure strip, the double-ended threaded column of the electric heating tube can be pressed down by gravity to be positioned and clamped at the support strip. At this time, the holding tool is positioned and placed in the cleaning box. When the magnetic needle of the magnetic polishing machine body grinds and polishes the surface of the electric heating tube, the electric heating tube in the clamped state is not easy to move, which effectively avoids the double-ended threaded column of the electric heating tube from colliding with the threaded column of other electric heating tubes and being damaged. The present invention is equipped with a holding tool A vibration lifting mechanism is provided, which can lift and lower the frame part of the holding tool when performing grinding and feeding in the cleaning box. After the grinding and polishing of the electric heating tube in the holding tool is completed, the vibration lifting mechanism lifts the electric heating tube on the frame part of the holding tool and provides vibration, so that the abrasive and liquid at the holding tool and the electric heating tube fall back into the cleaning box. The holding tool of the present invention can have multiple groups of frame parts to clamp the electric heating tubes in batches, and then the holding tool batches are sent into the cleaning box at the vibration lifting mechanism for semi-automatic cleaning, which greatly improves the convenience of grinding and polishing the electric heating tube at the magnetic polishing machine body, and can effectively solve the problems in the background technology.

[0064] Workers load the electric heating tube 16 according to the following steps:

[0065] The worker can hold the upper connecting plate 15 between the pressure strips 12 and lift it up, so that the pressure block formed by the pressure cylinder 18 and the ring pressure plate 19 welded together moves up at the non-threaded rod body of the threaded connecting rod 17, and then put the electric heating tubes 16 between the support strips 11 and the pressure strips 12 one by one, so that the threaded cylinders at both ends of the electric heating tubes 16 are stuck in the arc connection grooves 13 of the support strips 11, and then put down the upper connecting plate 15, and the pressure block formed by the pressure cylinder 18 and the ring pressure plate 19 welded together presses the pressure strips 12 against the threaded cylinders at both ends of the electric heating tubes 16 under the action of their own weight, and then the arc pressure grooves 14 of the pressure strips 12 cooperate with the arc connection grooves 13 of the support strips 11 to clamp the threaded cylinders at both ends of the electric heating tubes 16, and the workers can clamp and load the electric heating tubes 16 in batches on the frame parts of multiple groups of holding tooling 3 according to this feeding method;

[0066] The worker assembles the holding fixture 3 and the vibration-raising mechanism 25 according to the following steps;

[0067] The worker operates the electric push rod 31 to extend the telescopic rod upward, so that the disk connecting frame 29 with the L-shaped support plate 28 and the receiving socket 26 rises, and then the worker holds the oblique insertion strip 23 at the vertical connecting plate 22 of the holding tool 3, lifts the frame part of the holding tool 3 clamping the electric heating pipe 16, and then obliquely inserts the oblique insertion strip 23 into the receiving socket 26 of the L-shaped support plate 28, and the receiving socket 26 welcomes the oblique insertion of the oblique insertion strip 23 with the oblique entrance 27, so that the frame part of the holding tool 3 is obliquely pressed and hung on the receiving socket 26;

[0068] Then the worker operates the electric push rod 31 to descend, so that the frame part of the tool 3 held by the socket 26 is pressed into the cleaning box 2, and there is a T-shaped connecting plate 9 between the support bars 11 of the tool 3, which is clamped in the fixed block 5 of the fixed base 4 with the fixed groove 10 for positioning, and then the T-shaped connecting plate 9 is supported by the top bolt 8. At this time, the electric push rod 31 stops descending, and the T-shaped connecting plate 9 is supported by the top bolt 8 to maintain a certain space with the bottom inner box wall of the cleaning box 2, so that the support bar 11 and the electric heating tube 16 between the support bar 11 and the pressure bar 12 maintain a certain abrasive passing space with the bottom inner box wall of the cleaning box 2. At this time, stainless steel magnetic needle abrasives, polishing liquid and water are poured into the cleaning box 2, and then the magnetic polishing machine body 1 guides the stainless steel magnetic needle in the container through the high-speed rotating magnetic field to high-frequency impact the tube wall of the electric heating tube 16 in the medium of clean water and polishing liquid for grinding and polishing, so that the surface of the electric heating tube 16 has good smoothness and uniformity;

[0069] At this time, the electric push rod 31 rises and extends, thereby lifting the frame part of the tooling 3 away from the liquid and into the cleaning box 2. The worker operates the vibration motor 36 to connect the power and vibrate for a short time, so that the pressure strip 12 and the support strip 11 holding the tooling 3 vibrate, causing the abrasive and liquid to fall back into the cleaning box 2, and then turns off the vibration motor 36. At this time, the electric push rod 31 continues to rise, so that the support strip 11 leaves the box opening of the cleaning box 2, and then the worker can hold the I-shaped plate 20 to pull the oblique insertion strip 23 out of the receiving socket 26 , take away the frame part of the holding tool 3 of this group, and with the help of the lifting pressure strip 12 or the upper connecting plate 15, take out the electric heating tube 16 after grinding and polishing from between the pressure strip 12 and the supporting strip 11, and then take out the frame part of the holding tool 3 of the next group that clamps the electric heating tube 16, and reassemble it at the receiving socket 26 of the lifting mechanism 25 according to the above steps, and continue to lower the frame part of the holding tool 3 into the cleaning box 2, so that the electric heating tube 16 positioned and held by the holding tool 3 can be ground and polished by the magnetic polishing machine body 1.
