Description

Technical Field

[0001] The utility model relates to the technical field of oil dipstick processing, in particular to a device for sandblasting on both sides of a ruler. Background Art

[0002] In automobiles, the oil dipstick is a commonly used control scale to check the amount of lubricating oil in the lubricating oil hole. Since there is a turning path when the oil dipstick is inserted into the hole, the deformation of the oil dipstick during insertion is required to rebound and recover when it is pulled out. The existing oil dipstick needs to read the oil accurately, so the oil measuring area needs to be sandblasted to achieve the ideal oil hanging problem.

[0003] An existing manual sandblasting process for an oil dipstick generally uses tape to wrap part of the ruler body, leaving only the oil measuring area exposed. A sandblasting gun is used to blast the oil measuring area while rotating the ruler body. After sandblasting, the ruler body needs to be left alone to cure.

[0004] The above-mentioned prior art solutions have the following defects: manual sandblasting is time-consuming, labor-intensive and inefficient, the time control is imprecise, and the sand surface uniformity is poor. Utility Model Content

[0005] The utility model aims to provide a device for double-sided sandblasting of a ruler.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The invention comprises a closed sandblasting machine, wherein a sandblasting cavity is provided inside the sandblasting machine, a sandblasting device for spraying slurry is installed inside the sandblasting cavity, an entry hole connected to the sandblasting cavity is formed through the outer wall of the sandblasting machine, a partition is rotatably provided in the entry hole, a mounting base is extended from the outer wall of the sandblasting machine, a rotating and telescopic clamp is fixedly installed on the top wall of the mounting base, the rotating and telescopic clamp clamps a ruler body with one end inserted into the sandblasting cavity, the partition is provided with a ruler groove for the ruler body to pass through, ventilation holes are formed through the outer walls on both sides of the sandblasting machine, a heating rod is installed on the ventilation hole cover, and the sandblasting device comprises a mortar pipe for an external mortar output system, the mortar pipe is inserted into the interior of the sandblasting machine, and a sandblasting nozzle aligned with the ruler body is fixedly installed at the end of the mortar pipe.

[0008] By adopting the above technical solution, during use, first install the ruler strip body on the rotary telescopic fixture, then sleeve the partition on the ruler strip body so that the ruler strip body penetrates through the ruler strip slot by a certain distance, control the rotary telescopic fixture to send the ruler strip body into the sandblasting cavity until the partition is embedded into the penetration hole. At this time, start the sandblasting device to blast the ruler strip body penetrating into the sandblasting cavity. During the sandblasting process, the rotary telescopic fixture can position and rotate the ruler strip body so that the outer surface of the ruler strip body can be evenly sandblasted. After the sandblasting is completed, start the heating rod to quickly cure the sandblasting coating. After completion, control the rotary telescopic fixture to draw out the ruler strip body, remove the partition, and finally take out the ruler strip body to achieve the effect of high-efficiency sandblasting and drying, with high sandblasting uniformity and short curing time, having good product quality and high production efficiency.

[0009] Further, the ventilation holes include an air inlet hole and an air outlet hole. A rotating fan is installed in the middle of the air inlet hole and the air outlet hole. An air purification cylinder communicating with the air inlet hole is covered on the outer wall where the air inlet hole is located. The air purification cylinder is provided with a purification channel communicating with the air inlet hole along the length direction. The purification channel is filled with a porous water-absorbing filler. The material of the water-absorbing filler is sodium polyacrylate. A porous limiting plate is truncated and arranged on the inner wall close to the air inlet end of the purification channel. A porous dust-proof cover is covered on the outer wall where the air outlet is located.

[0010] By adopting the above technical solution, the water-absorbing filler made of sodium polyacrylate has a good water-absorbing effect. The rotating fan at the air outlet hole can continuously blow out the air inside the sandblasting cavity to form a negative pressure inside the sandblasting cavity, so that the outside air enters from the air inlet hole. The outside air can effectively filter out impurities and water vapor in the air through the porous water-absorbing filler. The rotating fan at the air inlet hole and the heating rod can continuously blow dry and clean high-temperature air to the ruler strip body, avoiding the adhesion of foreign impurities on the surface of the sandblasting coating and accelerating the rapid curing of the sandblasting coating, and can quickly form a sandblasting coating with good quality.

[0011] Further, the rotary telescopic fixture includes a first mounting plate fixedly connected to the mounting substrate. The first mounting plate faces the telescopic cylinder of the sandblasting machine. The end of the telescopic cylinder is fixedly provided with a pneumatic base that slides on the mounting substrate in a fitting manner. A rotary cylinder is rotatably arranged on the side of the pneumatic base away from the telescopic cylinder. A clamping base block is fixedly installed on the side of the rotary cylinder close to the sandblasting machine. The clamping base block is provided with a clamping groove for the ruler strip body to be fitted and placed. A locking bolt that penetrates through the outer wall of the clamping base block and abuts against the outer wall of the ruler strip body is arranged in the outer wall of the clamping base block. The locking bolt is threadedly engaged with the clamping base block. A rotating dial is fixedly installed at the end of the locking bolt passing through the outer wall of the clamping base block. The telescopic cylinder and the rotary cylinder are externally connected to a gas control system.

[0012] By adopting the above technical solution, the telescopic cylinder can effectively control the horizontal displacement of the clamping base to achieve the effect of controlling the strip body to approach or move away from the sandblasting machine. The rotary cylinder can further control the rotation direction and angle of the strip body, and cooperate with the rotating strip body during sandblasting and subsequent drying treatment to make the thickness of the sandblasting coating uniform, cured and flat. Turning the rotating dial can turn the locking bolt. When the locking bolt rotates, it can move away from or close to the strip body to achieve the effect of clamping or releasing the clamping of the strip body.

[0013] Further, the partition plate includes a left plate and a right plate that are arranged in contact with each other. The strip groove is arranged between the contact surfaces of the left plate and the right plate. Paired left positioning blocks and right positioning blocks are respectively extended on the outer walls of the left plate and the right plate. The left positioning blocks and the right positioning blocks are distributed at both ends of the outer wall on the side where the contact surface of the left plate and the right plate is located. The left positioning block is arranged in contact with the right positioning block, and a locking screw is penetrated through the left positioning block and the right positioning block, and a locking nut is provided for the locking screw.

[0014] By adopting the above technical solution, the partition plate is installed in the way of assembling the left plate and the right plate. When installing, just close the right side of the left plate and tighten the locking bolt and nut. When disassembling, operate in the reverse direction. While the strip groove can effectively block the sandblasting coating, the left and right split partition plates can effectively avoid the strip body with an increased thickness after sandblasting from rubbing against and damaging the sandblasting coating when passing through the strip groove again during use, and have a good coating protection effect compared with the structure of the whole partition plate plus the strip groove.

[0016] 1. The sandblasting machine, the sandblasting device, the rotary telescopic fixture, the ventilation hole and the heating rod are adopted, so that the rotary telescopic fixture can position and rotate the strip body, so that the outer surface of the strip body can be evenly sandblasted. After the sandblasting is completed, the heating rod is started to quickly cure the sandblasting coating, achieving the effect of high-efficiency sandblasting and drying;

[0017] 2. The rotating fan, the heating rod, the purification channel, the water-absorbing filler and the dust-proof cover are adopted to continuously blow dry and clean high-temperature air to the strip body, so as to avoid adhesion of foreign matters and impurities on the surface of the sandblasting coating and at the same time accelerate the rapid curing of the sandblasting coating, and quickly form a sandblasting coating with good quality;

[0018] 3. The left plate, the right plate, the locking screw and the nut are adopted, so as to effectively avoid the strip body with an increased thickness after sandblasting from rubbing against and damaging the sandblasting coating when passing through the strip groove again.
