Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a polyurethane ceramic undercut nozzle processing and fixing device. Background Technology

[0002] Polyurethane ceramic backwash nozzles are key wear-resistant components used in petrochemical, environmental protection, and other fields. Their main structure consists of a ceramic preform with internally converging frustum and cylindrical sections, surrounded by an externally wrapped, tapered, stepped polyurethane protective layer. This composite material design combines the high hardness of ceramics with the elastic cushioning properties of polyurethane, effectively improving the erosion and wear resistance of fluid transport systems.

[0003] After the initial manufacturing of polyurethane ceramic undercut nozzles, the polyurethane shell needs to be finely finished to improve the overall quality of the product. However, due to the high hardness but significant brittleness of the inner ceramic blank of the polyurethane ceramic undercut nozzle, and the fact that the outer polyurethane coating has good flexibility but insufficient mechanical strength, the fixtures of traditional machining lathes are difficult to hold stably and safely. Therefore, polyurethane ceramic undercut nozzles cannot be machined by lathe and can only be processed manually, which not only reduces the processing efficiency of polyurethane ceramic undercut nozzles but also reduces the processing quality. Utility Model Content

[0004] The purpose of this application is to provide a polyurethane ceramic undercut nozzle processing and fixing device to solve the technical problem in the prior art where, due to the material properties of the polyurethane ceramic undercut nozzle itself, the fixtures of traditional lathes cannot stably and safely clamp it, resulting in the inability to use traditional lathes for clamping and turning precision machining of the polyurethane ceramic undercut nozzle, and the need for manual processing, which reduces the processing efficiency and quality of the polyurethane ceramic undercut nozzle.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] A polyurethane ceramic undercut nozzle processing and fixing device for fixing the undercut nozzle, including a processing base, locking screws, positioning pins, pressure blocks and locking nuts;

[0007] The processing base has a fixing hole at its center. The locking screw is threaded into the fixing hole. The positioning pin is threaded onto the locking screw and is used to press against the inner wall of the end with the smaller opening area of ​​the sand-collecting nozzle. The pressure block is threaded onto the locking screw and is located at the end of the positioning pin away from the processing base. It is used to press down and fix the sand-collecting nozzle. The locking nut is threaded onto the locking screw and abuts against the pressure block.

[0008] In the polyurethane ceramic underrunner processing and fixing device described in the embodiments of this application, the pressure block is frustum-shaped and made of nylon, with its smaller end facing the processing base.

[0009] In the polyurethane ceramic undercut nozzle processing and fixing device described in the embodiments of this application, the positioning pin is threaded onto the locking screw at one end near the processing base and is supported on the processing base.

[0010] In the polyurethane ceramic undercut nozzle processing and fixing device described in the embodiments of this application, the pressure block is cylindrical.

[0011] In a polyurethane ceramic undercut nozzle processing and fixing device described in this application embodiment, the positioning pin is threaded onto the locking screw at the end away from the processing base and abuts against the pressure block.

[0012] In the polyurethane ceramic undercut nozzle processing and fixing device described in the embodiments of this application, the pressure block and the positioning pin are covered with a rubber layer with a thickness of 1mm.

[0013] In the polyurethane ceramic underrunner processing and fixing device described in the embodiments of this application, a connecting sleeve is further included. The connecting sleeve is threaded onto the locking screw, its bottom end is supported on the processing base, and its top end abuts against the positioning pin.

[0014] In the polyurethane ceramic undercut nozzle processing and fixing device described in the embodiments of this application, the positioning pin is provided with a rotary locking hole.

[0015] In the polyurethane ceramic undercut nozzle processing and fixing device described in the embodiments of this application, a fixing step is provided on the processing base.

[0016] Compared with the prior art, the embodiments of this application have the following beneficial effects:

[0017] As can be seen from the above technical solution, the polyurethane ceramic sink nozzle processing and fixing device provided in this application provides a sink nozzle supported on the processing base by setting a locking screw and a positioning pin on the processing base, with its inner side abutting against the positioning pin, thus achieving horizontal fixation of the sink nozzle. At the same time, the pressure block is threaded onto the locking screw, and when tightened, it presses the sink nozzle downward onto the processing base. After being pressed into place, it is locked by the locking nut, thus achieving vertical fixation of the sink nozzle. This solves the technical problem in the prior art where, due to the material properties of the polyurethane ceramic sink nozzle itself, the fixtures of traditional lathes cannot stably and safely clamp it, resulting in the inability to use traditional lathes for clamping and turning precision machining of the polyurethane ceramic sink nozzle, which can only be processed manually, reducing the processing efficiency and quality of the polyurethane ceramic sink nozzle.

[0025] Because the inner ceramic blank of polyurethane ceramic sink nozzle has high hardness but significant brittleness, and the outer polyurethane coating layer has good flexibility but insufficient mechanical strength, it is difficult for the fixtures of traditional machining lathes to hold it stably and safely. Therefore, polyurethane ceramic sink nozzles cannot be machined by lathe, which reduces the processing efficiency and quality of polyurethane ceramic sink nozzles.

[0026] In view of this, this application provides a polyurethane ceramic undercut nozzle processing and fixing device. The concept is to set a locking screw and a positioning pin on the processing base, with the undercut nozzle supported on the processing base and its inner side abutting against the positioning pin, thereby fixing the undercut nozzle in the horizontal direction. At the same time, the pressure block is threaded onto the locking screw, and when tightened, it presses the undercut nozzle downward onto the processing base. After being pressed into place, it is locked by the locking nut, thereby fixing the undercut nozzle in the vertical direction. This solves the technical problem in the prior art that, due to the material of the polyurethane ceramic undercut nozzle itself, the fixtures of traditional lathes cannot stably and safely clamp it, resulting in the inability to use traditional lathes to clamp and turn the polyurethane ceramic undercut nozzle for precision machining, and only manual processing is required, which reduces the processing efficiency and quality of polyurethane ceramic undercut nozzles.

[0032] Example 1

[0033] like Figures 1 to 2 As shown, Embodiment 1 of this application provides a polyurethane ceramic sink nozzle processing and fixing device, used to fix a sink nozzle 9 that needs to undergo head outer step surface processing. At this time, the end of the sink nozzle 9 with a larger opening area faces upward. A polyurethane ceramic sink nozzle processing and fixing device includes a processing base 1, a locking screw 2, a positioning pin 3, a pressure block 4, and a locking nut 5;

[0034] The processing base 1 has a fixing hole at its center with an internal thread. The locking screw 2 is threaded into the fixing hole. The positioning pin 3 is threaded onto the locking screw 2 and is used to abut against the inner wall of the smaller opening area of ​​the sand settling nozzle 9. Specifically, the positioning pin 3 is threaded onto the locking screw 2 at the end near the processing base 1 and is supported on the processing base 1. Its outer surface is covered with a 1mm rubber layer to prevent the positioning pin 3 from directly contacting the ceramic blank of the sand settling nozzle 9. The pressure block 4 is threaded onto the locking screw 2 and is located at the end of the positioning pin 3 away from the processing base 1. It is used to press down and fix the sand settling nozzle 9. Specifically, the pressure block 4 is frustum-shaped, made of nylon, and has a certain degree of elasticity. Its smaller end faces the processing base 1. The locking nut 5 is threaded onto the locking screw 2 and abuts against the pressure block 4.

[0035] The polyurethane ceramic sink nozzle processing and fixing device provided in Embodiment 1 of this application, when fixing the sink nozzle 9, the end of the sink nozzle 9 with a smaller opening area is supported on the processing base 1, and the inner wall of the end of the sink nozzle 9 with a smaller opening area abuts against the outer side of the positioning pin 3. The pressure block 4 is located inside the sink nozzle 9 and abuts against the ceramic blank of the frustum-shaped section inside the sink nozzle 9. As the pressure block 4 rotates toward the processing base 1, the pressure block 4 provides a pressure to the sink nozzle 9. Finally, the pressure block 4 is locked in a certain position by the locking nut 5 to achieve the fixing of the sink nozzle 9.

[0036] Example 2

[0037] like Figure 3 and Figure 4 As shown in Embodiment 2 of this application, a polyurethane ceramic undercut nozzle processing and fixing device is provided for fixing an undercut nozzle 9 that requires processing of the entire conical surface outside the tail. At this time, the end of the undercut nozzle 9 with a larger opening area faces downward. A polyurethane ceramic undercut nozzle processing and fixing device includes a processing base 1, a locking screw 2, a positioning pin 3, a pressure block 4, and a locking nut 5;

[0038] The processing base 1 has a fixing hole at its center with an internal thread. The locking screw 2 is threaded into the fixing hole. The positioning pin 3 is threaded onto the locking screw 2 and is used to abut against the inner wall of the end with the smaller opening area of ​​the sand settling nozzle 9. Specifically, the positioning pin 3 is threaded onto the end of the locking screw 2 away from the processing base 1, and its outer surface is covered with a 1mm rubber layer to prevent the positioning pin 3 from making complete hard contact with the ceramic blank of the sand settling nozzle 9. The pressure block 4 is threaded onto the locking screw 2, located at the end of the positioning pin 3 away from the processing base 1, and abuts against the positioning pin 3 to press down and fix the sand settling nozzle 9. Specifically, the pressure block 4 is cylindrical, and its outer surface is covered with a 1mm rubber layer to prevent the pressure block 4 from making complete hard contact with the sand settling nozzle 9. The locking nut 5 is connected to the locking screw 2 and abuts against the pressure block 4.

[0039] Preferably, in Embodiment 2 of this application, a connecting sleeve 6 is further included. The connecting sleeve 6 is threaded onto the locking screw 2, with its bottom end supported on the processing base 1 and its top end abutting against the positioning pin 3.

[0040] Preferably, in Embodiment 2 of this application, the processing base 1 is further provided with a fixed step 8 to prevent the sand-collecting nozzle 9 from moving horizontally on the processing plane.

[0041] The second embodiment of this application provides a polyurethane ceramic sink nozzle processing and fixing device. When fixing the sink nozzle 9, the end of the sink nozzle 9 with a larger opening area is supported on the processing base 1 and fastened to the fixing step 8, and the inner wall of the end of the sink nozzle 9 with a smaller opening area abuts against the outer side of the positioning pin 3. The pressure block 4 is located above the sink nozzle 9 and abuts against both the positioning pin 3 and the sink nozzle 9. As the pressure block 4 rotates toward the processing base 1, the pressure block 4 provides a downward pressure to the sink nozzle 9. Finally, the pressure block 4 is locked in a certain position by the locking nut 5 to achieve the fixing of the sink nozzle 9.

[0042] In Embodiments 1 and 2 of this application, the positioning pin 3 is provided with a rotating locking hole 7. The installer can insert a metal rod into the rotating locking hole 7, which makes it easier for the installer to adjust the position, disassemble or install the positioning pin 3.

[0043] In summary, the polyurethane ceramic undercut nozzle processing and fixing device provided in this application provides a fixing device for the undercut nozzle in the horizontal direction by setting a locking screw and a positioning pin on the processing base. The undercut nozzle is supported on the processing base, and its inner side abuts against the positioning pin. At the same time, the pressure block is threaded onto the locking screw. When tightened, it presses the undercut nozzle downward onto the processing base. After being pressed into place, it is locked by the locking nut, thus fixing the undercut nozzle in the vertical direction. This solves the technical problem in the prior art that, due to the material properties of the polyurethane ceramic undercut nozzle itself, the fixtures of traditional lathes cannot stably and safely clamp it, resulting in the inability to use traditional lathes for clamping and turning precision machining of polyurethane ceramic undercut nozzles. The only option is manual processing, which reduces the processing efficiency and quality of polyurethane ceramic undercut nozzles.
