Abstract
Description
Technical Field
[0001] This utility model relates to the field of intercooler tube surface weld grinding technology, specifically an intercooler tube surface grinding device. Background Technology
[0002] Grinding of intercooler tubes mainly involves manufacturing process optimization and defect repair. For burrs and weld slag after circumferential welding inside the intercooler tube, grinding can eliminate turbulence sources, reduce intake resistance, and ensure smooth airflow through the piping system. For burrs and weld slag after circumferential welding on the surface of the intercooler tube, the grinding precision of the pipe surface interface directly affects the clamping effect, preventing air leakage due to uneven surface, and avoiding problems such as power reduction and increased carbon buildup.
[0003] In the prior art, publication number "CN219485173U" discloses a surface grinding device for intercooler tubes, including a base. A connecting rod is slidably connected to the top of the base. A small rod is rotatably connected to the top of one connecting rod, and a small rod is fixedly connected to the top of the other connecting rod. A clamping frame is fixedly connected to the small rod. Sliding rods are slidably connected to both the top and bottom sides of the clamping frame. A bidirectional screw is rotatably connected to the clamping frame. The two sliding rods are threadedly connected to the bidirectional screw, and a retaining ring is fixedly connected to the sliding rod. A grinding mechanism is slidably connected to the top of the base. The beneficial effect of this utility model is that by allowing the two connecting rods to slide and the rotatable small rod to rotate, the clamping frame can be adjusted until the two clamping frames are inserted into both ends of the intercooler tube. By rotating the bidirectional screw, the sliding rod moves with the retaining ring, causing the retaining ring to press against the inner wall of the intercooler tube. This fixing method can fix both ends of the intercooler tube, resulting in a good fixing effect.
[0004] However, existing technologies still have significant shortcomings, such as:
[0005] In the aforementioned devices and existing technologies, straight and bent pipes are welded together during the welding and assembly of intercooler tubes. The grinding process usually involves rotating the intercooler tubes and using grinding rollers to perform contact grinding on the weld area. However, the bent pipes will detach from the grinding rollers during the rotation process, making it difficult to effectively grind the weld seam at the connection between the bent pipes and the straight pipes, resulting in poor grinding effect on the surface of the intercooler tubes. Utility Model Content
[0006] The purpose of this invention is to provide a grinding device for the surface of intercooler tubes to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for the surface of an intercooler tube, comprising a base, a tube seat, a lifting cylinder, a grinding table, and a grinding unit for the weld seam on the outer surface of the intercooler tube.

Detailed Implementation
[0023] 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.
[0024] Please see Figure 1-5 This utility model provides a technical solution:
[0025] Example 1: A grinding device for the surface of intercooler tubes: including a base 1, a tube seat 2, a lifting cylinder 3, a grinding table 4, and a grinding unit for the weld seam on the outer surface of the intercooler tubes. The tube seat 2 is rotatably mounted in the central area of the surface of the base 1. Two sets of lifting cylinders 3 are symmetrically mounted on the surface of the base 1. A column 11 is mounted on the top of the base 1. The grinding table 4 is mounted on the top of the column 11. The moving end of the lifting cylinder 3 moves through the surface of the grinding table 4. A central sleeve 8 is installed through the central area of the surface of the grinding table 4. The grinding unit for the weld seam on the outer surface of the intercooler tubes is located on the top of the grinding table 4 and is used to perform multi-station grinding on the weld seam area of the outer surface of the intercooler tubes.
[0026] The intercooler tube outer surface weld grinding unit includes an X-axis grinding section, which includes a grinding frame 5. The grinding frame 5 is mounted on the moving end of the lifting cylinder 3. A linear guide rail 51 is embedded in the surface of the grinding frame 5. An X-axis grinding seat 52 is mounted on the moving end of the linear guide rail 51. An X-axis electrically driven grinding roller 53 is mounted on the surface of the X-axis grinding seat 52.
[0027] The intercooler tube outer surface weld grinding unit also includes a Y-axis grinding section, which includes a top cover 6. The top cover 6 is installed on the top of the grinding frame 5. A Y-axis grinding seat 7 is installed on the top of the top cover 6. A Y-axis electric drive grinding roller 71 is installed on one side of the Y-axis grinding seat 7.
[0028] In this embodiment, after the X-axis grinding base 52 is unfolded into place, the X-axis electric grinding roller 53 installed on the surface of the X-axis grinding base 52 will come into contact with the weld area of the bent pipe and the straight pipe on the surface of the intercooler tube. The two sets of X-axis electric grinding rollers 53 rotate to grind the weld area. The intercooler tube continues to rotate during the grinding process, so that the weld area of the bent pipe and the straight pipe can be fully contacted and ground by the two sets of X-axis electric grinding rollers 53, ensuring the grinding effect of the weld area of the bent pipe and the straight pipe. The bottom area of the intercooler tube near the top end face can be ground by contact grinding through the Y-axis electric grinding roller when the grinding frame 5 is pushed up by the lifting cylinder 3, which can avoid burr residue in the bottom area of the intercooler tube near the top end face.
[0029] An electric turntable is installed in the center of the base 1, and the tube seat 2 is installed on top of the electric turntable.
[0030] The surface of the top cover 6 is equipped with a dust extraction unit for grinding the weld seams of the intercooler tubes.
[0031] The intercooler tube weld grinding and dust extraction unit includes an X-axis dust extraction chamber 91 and a Y-axis dust extraction chamber 92. The X-axis dust extraction chamber 91 is installed on the surface of the top cover 6 near the X-axis electric drive grinding roller 53 area, and the Y-axis dust extraction chamber 92 is installed on one side of the Y-axis grinding seat 7. The surface of the top cover 6 is also equipped with a filter main chamber 9.
[0032] The main filter chamber 9 is connected to the X-axis dust collection chamber 91 via air pipe 911, and the main filter chamber 9 is connected to the Y-axis dust collection chamber 92 via air pipe 921.
[0033] In this embodiment, when grinding the surface of the intercooler tube, in order to avoid the working conditions of welding slag dust pollution, an external fan can be set to extract airflow from the main filter chamber 9. The main filter chamber 9 will centrally filter the dust gas extracted from the X-axis dust collection chamber 91 and the Y-axis dust collection chamber 92, thereby avoiding the working conditions of welding slag dust pollution.
[0034] Working principle: The operator first pre-clamps the welded and assembled intercooler tubes. During clamping, the intercooler tube is inserted into the central sleeve 8 in the center area of the grinding table 4 until it is inserted into the inner cavity of the tube seat 2. Then, support washers are filled into the tube seat 2 and the intercooler tube to prevent the intercooler tube from loosening when the tube seat 2 rotates. When the intercooler tube is calibrated and positioned, it will rotate concentrically with the tube seat 2 along the central sleeve 8. After the rotation center of the intercooler tube is fixed, excessive vibration of the intercooler tube during grinding can be reduced. To further reduce the vibration of the middle section of the intercooler tube... If the area vibrates, the electric drive shaft 82 in the drive clamp 81 area can drive the L-shaped clamp arm 83 and the arc-shaped clamp 84 to wrap the middle section of the intercooler tube in a ring shape. The arc-shaped clamp 84 has balls embedded in its arc-shaped inner surface. The balls will fit against the surface of the intercooler tube. When the intercooler tube rotates, the balls roll to support the outer surface of the intercooler tube, which can effectively avoid the risk of the intercooler tube breaking during rotation. In order to avoid wear on the surface of the intercooler tube, external lubricating medium can be added to effectively ensure the surface polishing condition of the intercooler tube.
[0035] Once the intercooler tubes are clamped in place, contact grinding of the weld area can be performed. Since the bent and straight sections are the main grinding areas, two sets of grinding points are provided for grinding these areas. Two sets of X-axis grinding seats 52 are driven to unfold by linear guide rails 51. After the X-axis grinding seats 52 are unfolded in place, the X-axis electric grinding rollers 53 installed on the surface of the X-axis grinding seats 52 will come into contact with the weld areas of the bent and straight sections on the surface of the intercooler tubes. The two sets of X-axis electric grinding rollers 53 rotate to grind the weld areas. The intercooler tubes continue to rotate during the grinding process, so that the weld areas of the bent and straight sections can get full contact grinding from the two sets of X-axis electric grinding rollers 53, ensuring the grinding effect of the weld areas of the bent and straight sections.
[0036] When grinding the surface of the intercooler tubes, in order to avoid the pollution of the working conditions by welding slag dust, an external fan can be set up to extract airflow from the main filter chamber 9. The main filter chamber 9 will centrally filter the dust gas extracted from the X-axis dust collection chamber 91 and the Y-axis dust collection chamber 92, thereby avoiding the pollution of the working conditions by welding slag dust.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
