Description

Technical Field

[0001] This utility model relates to the field of air flotation sleeve processing technology, specifically to a blower tube structure. Background Technology

[0002] An air-floating sleeve is a component used in the field of air-floating technology. It utilizes gas (usually air) to form an air film between the sleeve and related components to achieve functions such as frictionless or low-friction movement, support, or isolation. In the manufacturing process of air-floating sleeve products, the most common problem is excessive burrs at the cross-hole positions. Due to the excessive porosity of the workpiece, burrs will inevitably be generated during processing. In order to ensure the cleanliness of the product, a subsequent burr removal process is required.

[0003] Currently, when using blower tubes, there is a lack of auxiliary air hole edge cleaning mechanisms. The time spent cleaning burrs is usually included in the working hours, resulting in low production efficiency and high processing costs. At the same time, the burr cleaning methods used, such as using dry ice or scalpels, cannot guarantee complete burr removal and also increase labor costs. Therefore, a blower tube structure is proposed to add an air hole edge cleaning mechanism by means of sleeve, rotation, and blowing. This mechanism can clean the burrs on the edges of the air holes in the air-floating workpiece, thereby cleaning the burrs in the narrow space inside the air-floating sleeve workpiece, improving the efficiency of burr removal and ensuring the cleanliness of the workpiece. Utility Model Content

[0007] By adopting the above technical solution, an air hole edge cleaning mechanism can be added to clean the burrs on the edges of the air holes inside the air-floating workpiece, thereby cleaning the burrs in the narrow space inside the air-floating sleeve workpiece, improving the efficiency of burr removal and ensuring the cleanliness of the workpiece product.

[0008] Specifically, the guide assembly includes a support plate, a gear ring is provided on the top of the support plate, and the gear ring is fixedly connected to a long tube by adhesive bonding. The top of the support plate is located on one side of the gear ring and is rotatably connected to a transmission gear by a rotating shaft. The transmission gear is meshed with the gear ring. The bottom of the support plate is connected to a rotary motor by bolts, and the rotary motor is connected to the transmission gear by a drive shaft.

[0009] By adopting the above technical solution, the meshing connection transmission can be used to drive the thin tube to rotate back and forth, increasing the range and area of ​​burr removal, while improving the uniformity of the removal.

[0010] Specifically, the end of the long tube is provided with an external thread, and the long tube is connected to a self-tapping screw sleeve through the external thread. The top of the long tube is provided with a dry ice delivery tube.

[0011] By adopting the above technical solution, the external thread facilitates the assembly and use of the self-tapping sleeve of the long pipe threaded connection to the thin pipe, and the dry ice delivery pipe can deliver dry ice into the thin pipe for burr cleaning.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To facilitate the addition of a pore edge cleaning mechanism, burrs on the edges of pores inside the air-float workpiece are removed, thereby cleaning the burrs in the narrow space inside the air-float sleeve workpiece. Figure 1-3 As shown, the present invention provides a blower tube structure, which includes a blower tube assembly 1 and a guide assembly 2. The blower tube assembly 1 is surrounded by the guide assembly 2. The blower tube assembly 1 includes a long tube 3 and a thin tube 4.

[0024] The thin tube 4 has a tube wall air outlet 401 on its surface, and a channel 402 is provided inside the thin tube 4, which is connected to the tube wall air outlet 401. A self-tapping screw sleeve 403 is provided at the end of the thin tube 4 inside the channel 402.

[0025] In use, the long tube 3, the thin tube 4, the air outlet 401 on the tube wall, the channel 402 and the self-tapping screw sleeve 403 can be used to increase the air hole edge cleaning mechanism, clean the burrs on the edge of the air hole in the air-floating workpiece, thereby cleaning the burrs in the narrow space inside the air-floating sleeve workpiece, improving the efficiency of burr cleaning and ensuring the cleanliness of the workpiece product.

[0026] To improve the scope and efficiency of cleaning, for example, such as Figure 1 , Figure 4 As shown, the present invention also includes the following: the guide assembly 2 includes a support plate 201, the top of the support plate 201 is provided with a gear ring 202, and the gear ring 202 is fixedly connected to the long tube 3 by adhesive bonding; the top of the support plate 201 is located on one side of the gear ring 202 and is rotatably connected to a transmission gear 203 by a rotating shaft, and the transmission gear 203 is meshed with the gear ring 202; the bottom of the support plate 201 is connected to a rotary motor 204 by bolts, and the rotary motor 204 is connected to the transmission gear 203 by a drive shaft.

[0027] In use, the support plate 201, gear ring 202, transmission gear 203 and rotary motor 204 can drive the thin tube 4 to reciprocate through meshing connection transmission, increasing the burr cleaning range and area, and improving the uniformity of cleaning.

[0028] For example, such as Figure 2 As shown, the present invention also includes an external thread 301 at the end of the long tube 3, and a self-tapping sleeve 403 is threadedly connected to the long tube 3 through the external thread 301. A dry ice conveying pipe 5 is provided at the top of the long tube 3.

[0029] In use, the external thread 301 facilitates the assembly and use of the self-tapping sleeve 403 of the long tube 3 to connect the thread to the thin tube 4, and the dry ice delivery pipe 5 can deliver dry ice into the thin tube 4 for burr removal.

[0030] For example, such as Figure 5 As shown, the present invention also includes an opening 205 in the support plate 201, and the opening 205 is sleeved with a long tube 3. An annular slide 206 is provided in the opening 205, and an arc-shaped slider 207 is slidably connected in the annular slide 206. The arc-shaped slider 207 is fixedly connected to the long tube 3 by screws.

[0031] In use, the opening 205, the annular slide 206 and the arc-shaped slider 207 can be used to add an auxiliary guiding mechanism, and the stability of the thin tube 4 can be improved by using the annular limit sliding method.

[0032] For example, such as Figure 4 As shown, the present invention also includes a mounting plate 208 connected to one side of the support plate 201 by bolts, and the surface of the mounting plate 208 is provided with mounting holes 209.

[0033] During use, the mounting plate 208 and mounting holes 209 facilitate the pre-fixing and installation of the support plate 201.

[0034] When using this utility model, the operator first selects the corresponding thin tube 4 according to the size of the inner hole of the air flotation sleeve, and uses the self-tapping sleeve 403 to connect the external thread 301 at the end of the long tube 3, so that the long tube 3 and the thin tube 4 are assembled to adapt to different sizes of the inner hole diameter of the air flotation sleeve. Then, the operator inserts it into the openings at both ends of the air flotation sleeve workpiece, and blows it through the dry ice conveying pipe, the long tube 3, the thin tube 4 and the air outlet 401 on the pipe wall to clean the burrs. This not only ensures a high level of cleanliness and reduces labor costs, but also improves processing efficiency.

[0035] Furthermore, during the actual cleaning process, the rotary motor 204 can be manually turned on to drive the transmission gear 203 to rotate. The meshing gear ring 202 drives the long tube 3 and the thin tube 4 to rotate back and forth until the burrs on the edge of the small air hole are cleaned. This not only increases the range and area of ​​burr cleaning by blowing, but also makes the cleaning more uniform and reliable. It also helps to improve the quality of burr cleaning and makes the use more reasonable and convenient.
