Description

Technical Field

[0001] This invention relates to the field of instrument housing processing technology, specifically to a deburring device for instrument housing processing. Background Technology

[0002] Instrument housings are indispensable components in many instruments. They mainly serve to install the structure, protect the internal structure, and enhance the appearance. Typically, instrument housings used in daily life are round or cylindrical in shape, such as the housings of common pressure gauges and water flow meters. Their manufacturing process is mostly to produce them by stamping metal sheets.

[0003] However, due to the inherent defects of the stamping process, burrs often remain at the opening of the cylinder after stamping, which is not only unsightly but also easily scratches workers. It also brings considerable trouble to the installation of other components. For example, it is difficult to eliminate the assembly gap between the cylinder and the glass sealing cover. In the existing deburring process of instrument housing, manual grinding is mostly used, which is labor-intensive and inefficient. Moreover, since it is difficult to maintain the consistency of the action during manual grinding, it is not conducive to the production and quality control of large-scale instrument housing products. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a deburring device for instrument housing processing, which solves the problem that the existing deburring process for instrument housings mostly relies on manual grinding, which is inefficient and makes it difficult to maintain consistency in manual grinding, thus hindering the production and quality control of large-volume instrument housing products.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a deburring device for instrument housing processing, comprising an operating table, a grinding disc mounted on the top of the operating table, a through hole in the middle of the grinding disc, a main shaft rotatably connected to the middle of the operating table, the top end of the main shaft passing through the through hole in the middle of the grinding disc and mounted with a rotating wheel, a pair of curved grooves symmetrical about the center point of the rotating wheel being formed on both sides of the interior of the rotating wheel, the outer end openings of the curved grooves communicating with the outside from the two side edges of the rotating wheel, the inner end openings of the curved grooves extending spirally toward the center point of the rotating wheel, a driven wheel mounted on the bottom of the main shaft, a drive cam provided on the side of the driven wheel, and when the drive cam rotates, only the wheel side surface at its flange can fit tightly against the wheel side surface of the driven wheel.

[0006] Preferably, the grinding disc has multiple fan-shaped assembly cavities around its interior, and each fan-shaped assembly cavity has a sandpaper support base inside.

[0007] Preferably, the inner and outer sides of the sandpaper support base both have platforms protruding outwards, and the bottom of the sanding disc is equipped with an electromagnet located in the middle of the inner and outer sides of the fan-shaped assembly cavity. The bottom of the electromagnet can be magnetically attracted to the inner and outer platforms of the sandpaper support base respectively.

[0008] Preferably, the grinding disc has discharge ports on both sides near its center point.

[0009] Preferably, the top of the grinding disc is equipped with a top cover, and the top cover has a material discharge port on both sides inside.

[0010] Preferably, a discharge pipe is installed on both sides of the top of the top cover, and the bottom port of the discharge pipe is aligned with the discharge port on both sides.

[0011] Preferably, a motor is installed on one side of the bottom of the operating table, and the driving end of the motor is installed in the middle of the driving cam.

[0012] Working principle: Based on the required grinding precision, the required grit of sandpaper is first laid on the upper surface of the sandpaper support base. Then, the sandpaper support bases, along with the sandpaper, are embedded into the fan-shaped assembly cavity, ensuring the upper surface of the sandpaper is flush with the upper surface of the grinding disc. The motor then drives the drive cam to rotate. Because only the wheel side of the drive cam's flange can tightly engage with the wheel side of the driven wheel during rotation, the driven wheel will exhibit intermittent rotational motion. The wheel side of the drive cam flange... The length of the drive cam is half its circumference, which means the driven wheel can only rotate half a turn each time. The position of the rotating disc is adjusted so that when it stops after rotating half a turn, its outer end slot aligns with the material outlet of the top cover. Then, instrument housings are stacked inside the material tube with the surface to be ground facing down. When the material outlet aligns with the outer end slot of the rotating disc, the bottommost instrument housing will automatically fall into the curved channel. When the rotating disc rotates, it can push the instrument housing through the edge of the curved channel. The casing moves against the upper surface of the sandpaper, and through relative friction with the sandpaper, the bottom of the instrument casing is deburred. Because the inner end of the curved groove extends spirally towards the center of the rotating wheel, as the rotating wheel continues to rotate, the instrument casing is "embraced" by the curved groove and pushed towards its inner end. After continuous pushing, the instrument casing moves to the inner end of the curved groove, and then, when the inner end of the curved groove meets the outer end... When the material inlets are fully aligned and connected, the instrument housing at the inner end of the curved channel can fall onto the top of the operating table through the discharge port, thus achieving the effect of automatic material unloading after grinding. This process can be repeated to achieve continuous grinding of multiple instrument housings. Since the movement distance of each instrument housing is almost the same, the degree of grinding and deburring of the instrument housings can be well unified, which is convenient for quality control. Furthermore, when the instrument housing enters the curved channel, the top cover restricts the movement of the instrument housing, ensuring that the instrument housing is in close contact with the upper surface of the sandpaper, thus ensuring the stable grinding and deburring process.

[0013] This invention provides a deburring device for instrument housing processing. It has the following beneficial effects:

[0014] This invention uses curved channels to push the instrument housing against the upper surface of sandpaper, achieving the purpose of deburring. Because the inner ends of the curved channels extend spirally towards the center of the rotating disk, as the disk continues to rotate, the instrument housing is "embraced" and pushed towards the inner ends of the channels. After continuous pushing, it is automatically discharged through the outlet. This cycle repeats, enabling continuous grinding of multiple instrument housings. Since the movement distance of each instrument housing is nearly identical, the degree of deburring is well-uniformed, facilitating quality control. This invention solves the problem that existing instrument housing processing deburring steps often rely on manual grinding, which is inefficient and makes it difficult to maintain consistency, hindering the production and quality control of large batches of instrument housings.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example:

[0026] like Figure 1-8 As shown, this embodiment of the invention provides a deburring device for instrument housing processing, including an operating table 1. A grinding disc 6 is installed on the top of the operating table 1. A through hole is opened in the middle of the grinding disc 6. A discharge port 7 is opened on both sides of the grinding disc 6 near its center point. A main shaft 2 is rotatably connected to the middle of the operating table 1. The top end of the main shaft 2 passes through the through hole in the middle of the grinding disc 6 and is equipped with a rotating wheel 11. A pair of curved grooves 12 symmetrical about the center point of the rotating wheel 11 are opened on both sides of the interior of the rotating wheel 11. The outer end slots of the curved grooves 12 are respectively connected to the outside from the two side edges of the rotating wheel 11. The inner end slots of the curved grooves 12 are respectively spiraled and extended towards the center point of the rotating wheel 11.

[0027] Furthermore, the interior of the grinding disc 6 is provided with multiple fan-shaped assembly cavities 8, and each fan-shaped assembly cavity 8 is provided with a sanding paper support base 10.

[0028] According to the required grinding precision, the required grit of sandpaper is first laid on the upper surface of the sandpaper support base 10. Then, each sandpaper support base 10, together with the sandpaper, is embedded into the inside of the fan-shaped assembly cavity 8, and the upper surface of the sandpaper is kept flush with the upper surface of the grinding disc 6. When the rotating disc 11 rotates, the instrument housing in the curved channel 12 can be pushed to move against the upper surface of the sandpaper by friction through the groove edge of the curved channel 12. Through the relative frictional movement between the sandpaper and the instrument housing, the bottom of the instrument housing can be ground and deburred.

[0029] Furthermore, a driven wheel 3 is installed at the bottom end of the main shaft 2, and a drive cam 5 is provided on the side of the driven wheel 3. When the drive cam 5 rotates, only the wheel side at its flange can fit tightly with the wheel side of the driven wheel 3. A motor 4 is installed on one side of the bottom of the operating table 1, and the drive end of the motor 4 is installed in the middle of the drive cam 5.

[0030] The operation of the aforementioned motor 4 will drive the drive cam 5 to rotate. Since only the wheel side of its flange can fit tightly with the wheel side of the driven wheel when the drive cam rotates, the driven wheel 3 will exhibit intermittent rotational motion. In this embodiment, the length of the wheel side of the flange of the drive cam 5 is set to account for half of the circumference of the drive cam 5, so that the driven wheel 3 can only rotate half a turn each time. Adjust the position of the rotating disk 11 so that when the rotating disk 11 stops rotating half a turn each time, its outer end slot can be aligned with the material outlet of the top cover 13. Then, the instrument housings are stacked in sequence inside the material outlet tube 14 with the surface to be polished facing down. When the material outlet is aligned with the outer end slot of the rotating disk 11, the bottommost instrument housing will automatically fall into the curved channel 12, realizing the automatic feeding function.

[0031] Furthermore, the inner and outer sides of the sandpaper support base 10 both have platforms protruding outwards, and the bottom of the sanding disc 6 is equipped with electromagnets 9 located in the middle of the inner and outer sides of the fan-shaped assembly cavity 8. The bottom of the electromagnets 9 can be magnetically attracted to the inner and outer platforms of the sandpaper support base 10 respectively.

[0032] The above design facilitates the installation of the sandpaper support base 10, thereby making it easier to replace sandpaper with different types to meet different needs and making it more convenient to use.

[0033] Furthermore, to ensure that the instrument housing is tightly attached to the upper surface of the sandpaper and to ensure stable sanding and deburring, a top cover 13 is installed on the top of the sanding disc 6. The top cover 13 has a discharge port on both sides inside, and a discharge pipe 14 is installed on both sides of the top of the top cover 13. The bottom end of the discharge pipe 14 is aligned with the discharge port on both sides.

[0034] Once the instrument housing enters the curved channel 12, due to the restriction of the top cover 13, the instrument housing will be tightly attached to the upper surface of the sandpaper, ensuring stable sanding and deburring.

[0035] Furthermore, this embodiment also provides a complete workflow:

[0036] First, according to the required grinding precision, the required grit of sandpaper is first laid on the upper surface of the sandpaper support base 10. Then, each sandpaper support base 10 together with the sandpaper is embedded into the inside of the fan-shaped assembly cavity 8, and the upper surface of the sandpaper is kept flush with the upper surface of the grinding disc 6.

[0037] Second, the operation of motor 4 will drive the drive cam 5 to rotate. Since only the wheel side of its flange can fit tightly with the wheel side of the driven wheel when the drive cam rotates, the driven wheel 3 will exhibit intermittent rotational motion. In this embodiment, the length of the wheel side of the flange of the drive cam 5 is set to account for half of the circumference of the drive cam 5, so that the driven wheel 3 can only rotate half a turn each time. Adjust the position of the rotating disk 11 so that when the rotating disk 11 stops after rotating half a turn each time, its outer end slot can be aligned with the discharge port of the top cover 13.

[0038] Third, the instrument housings are stacked in sequence inside the feed pipe 14 with the surface to be polished facing down. When the feed port is aligned with the outer end slot of the rotating wheel 11, the bottommost instrument housing will automatically fall into the curved channel 12.

[0039] Fourth, when the rotating wheel 11 rotates, the instrument housing can be pushed to move against the upper surface of the sandpaper by the groove edge of the curved channel 12. Through the relative frictional movement between the instrument housing and the sandpaper, the bottom of the instrument housing can be polished and deburred. Since the inner end of the curved channel 12 extends spirally towards the center point of the rotating wheel, when the rotating wheel 11 continues to rotate, the instrument housing will be "embraced" by the curved channel 12 and pushed towards the inner end of the curved channel 12. After continuous pushing, the instrument housing can move to the inner end of the curved channel 12.

[0040] 5. When the inner end of the curved channel 12 is fully aligned and connected with the discharge port 7, the instrument housing at the inner end of the curved channel 12 can fall onto the top of the operating table 1 through the discharge port 7, thereby achieving the effect of automatic material feeding after grinding. By repeating this process, multiple instrument housings can be ground continuously.

[0041] VI. Since the movement distance of each instrument housing is almost the same, the degree of grinding and deburring of the instrument housing can be better unified, which is convenient for quality control. Furthermore, when the instrument housing enters the curved channel 12, the top cover 13 restricts it so that the instrument housing can be kept in close contact with the upper surface of the sandpaper, ensuring the stable grinding and deburring.

[0042] This instrument housing deburring device, through its simple mechanical structure and ingenious curved groove 12 design, solves the problem that the existing instrument housing deburring process mostly relies on manual grinding, which is inefficient and makes it difficult to maintain consistency in manual grinding, thus hindering the production and quality control of large-volume instrument housing products.

[0043] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
