Specific implementation mode

[0031] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0032] Embodiment 1:

[0033] Refer to the attached Figure 1 、attached Figure 2 And attached Figure 3 , a polishing device for metal hose parts, including a base 10, a first drive motor 11 is fixedly arranged in the base 10, the output end of the first drive motor 11 is connected with a turntable 12, a first support rod 13 is fixedly arranged at the center of the upper end surface of the turntable 12, a first connection block 14 is fixedly arranged on the upper end surface of the first support rod 13, a plurality of second drive motors 15 are fixedly arranged on the side surface of the first connection block 14, the output end of each second drive motor 15 is connected with a second support rod 16, and the other end of the second support rod 16 is connected with a fixing component.

[0034] The first drive motor 11 in the base 10 can drive the turntable 12 and all the parts thereon to rotate together. After the metal joint is fixed on the fixing component, the first drive motor 11 driving the turntable 12 to rotate can realize the conversion of the metal joint at different workstations.

[0035] Further, refer to the attached Figure 1 、attached Figure 3 、attached Figure 4 、attached Figure 6 And attached Figure 7, on one upper side of the base 10, two first support plates 22 are fixedly arranged, a second support plate 24 is connected and arranged between the two first support plates 22 in the vertical direction, and a third support plate 38 is connected and arranged on the upper end faces of the two first support plates 22. The second support plate 24 and the third support plate 38 serve to place the polishing tool.

[0036] Further, refer to Appendix Figure 3 , Appendix Figure 4 , Appendix Figure 5 and Appendix Figure 6 , on one side of the second support plate 24 close to the first support rod 13, a fourth electric push rod 33 is fixedly arranged, and a polishing brush head 34 is connected to the output end of the fourth electric push rod 33. During the subsequent polishing process, the polishing belt 30 and the polishing brush head 34 do not rotate. The second drive motor 15 arranged on the side of the first connection block 14 can drive the second support rod 16 and the fixing component to rotate and the metal joint on the fixing component to rotate, so that the polishing belt 30 and the polishing brush head 34 can polish the metal joint.

[0037] For the states of each part during polishing, refer to Appendix Figure 4 , the polishing brush head 34 and the fixing component are at the same height. When the first drive motor 11 drives the turntable 12 to turn the fixed metal joint to the polishing station, the production personnel can control the output end of the fourth electric push rod 33 to advance and insert the polishing brush head 34 into the inner wall of the metal joint. The second drive motor 15 can drive the second support rod 16, the fixing component, and the metal joint fixed on the fixing component to rotate, so that the polishing brush head 34 can polish the inner wall of the rotating metal joint; when the polishing brush head 34 polishes the inner wall of the metal joint, the fourth electric push rod 33 can still control the output end to advance and retreat to drive the polishing brush head 34 thereon to repeatedly polish the inner wall of the metal joint.

[0038] Further, refer to Appendix Figure 4 and Appendix Figure 6 , the bristles on the polishing brush head 34 have a certain elasticity, can adapt to the metal inner wall within a certain size range, and polish it.

[0039] Further, refer to Appendix Figure 1 , Appendix Figure 3 , Appendix Figure 4 , Appendix Figure 6 and Appendix Figure 7, a second fixing groove 39 is provided on the third support plate 38, and a second electric push rod 27 is fixedly provided on the upper end surface of the third support plate 38. The output end of the second electric push rod 27 is connected to a propulsion frame 28. The propulsion frame 28 passes through the second fixing groove 39 and extends to the lower end surface of the third support plate 38. A third fixing groove 40 is further provided on the lower end surface of the third support plate 38. The propulsion frame 28 can be slidably fitted in the third fixing groove 40; on the lower end surface of the propulsion frame 28, two third electric push rods 29 are symmetrically arranged on both sides of the polishing brush head 34, and a polishing belt 30 is connected between the output ends of the two third electric push rods 29.

[0040] Further, refer to the appendix Figure 1 With the appendix Figure 7 , a liquid storage seat 35 is fixedly provided on the second support plate 24 below the polishing belt 30. A first spray head 36 and a second spray head 37 are fixedly provided on one side of the liquid storage seat 35 close to the center of the base 10. The first spray head 36 is aligned with the outer wall of the metal, and the second spray head 37 is aligned with the inner wall of the metal. When the device polishes the metal joint, the first spray head 36 and the second spray head 37 can spray polishing liquid to the polishing part to assist polishing, thereby improving the overall polishing effect.

[0041] During polishing, the production personnel can control the output end of the third electric push rod 29 to move downward, press the polishing belt 30 tightly against the outer wall of the metal joint to be polished. The polishing belt 30 is made of an elastic material, and the third electric push rods 29 at both ends can continue to move downward to tighten the polishing belt 30 on the outer wall of the metal joint to be polished. When the metal joint is driven to rotate, the polishing belt 30 can polish the outer wall of the metal joint. Subsequently, the production personnel can drive the propulsion frame 28, the third electric push rod 29 and the polishing belt 30 on the output of the third electric push rod 29 to move forward and backward by controlling the output end of the second electric push rod 27 to polish different steps on the outer wall of the metal joint.

[0042] Further, refer to the appendix Figure 11 , a plurality of first support ribs 31 and second support ribs 32 are fixedly provided on the upper end surface of the polishing belt 30. The polishing belt 30 is made of an elastic material. The first support ribs 31 and the second support ribs 32 are both elastic metal wires with a certain hardness. The arrangement of the first support ribs 31 and the second support ribs 32 makes the polishing belt 30 have a certain hardness while having elasticity, so that the polishing belt 30 has a certain stability when pressing against the outer wall of the metal joint for polishing.

[0043] Further, for the outer wall of some metal joints with special stepped shapes, such as the outer wall of a concave-shaped metal joint, it will cause the polishing belt 30 to get stuck in it, making the second electric push rod 27 unable to continue to advance and polish the metal joint of the next step. At this time, the production personnel can control the output end of the third electric push rod 29 to retract, drive the polishing belt 30 on the output end of the third electric push rod 29 to rise, and then reposition and polish the next section of the metal outer wall.

[0044] Specifically, initially, the production staff first place the metal joint to be fixed on the fixing component. Subsequently, the production staff control the first driving motor 11 to drive the turntable 12 to rotate, and then the production staff can fix the next metal joint to be polished on the next fixing component. The previously fixed metal joint will be rotated closer to the polishing station until it enters the polishing station for polishing. The specific number of stations can be arranged differently by the production staff according to the processing time and process, and this solution does not impose too many restrictions.

[0045] During polishing, the production staff control the output end of the fourth electric push rod 33 to feed in, so that the polishing brush head 34 extends into the inner wall of the metal joint to be polished to complete the preparation for polishing. At the same time, the output ends of the two third electric push rods 29 on the lower end surface of the propulsion frame 28 feed in to press the polishing belt 30 against the outer end surface of the metal joint. Subsequently, the production staff control the second driving motor 15 to drive the second support rod 16, the fixing component and the metal joint thereon to rotate, so that the polishing brush head 34 can polish the inner wall of the metal joint, and the polishing belt 30 can polish the outer wall of the metal joint. During this process, the output end of the second electric push rod 27 can control the propulsion frame 28, the two third electric push rods 29 and the polishing belt 30 on the output ends of the third electric push rods 29 to move in the horizontal direction, so that the polishing belt 30 can polish the stepped outer wall of the metal joint in stages.

[0046] After polishing is completed, the production staff first control the second driving motor 15 to stop, so that the second support rod 16, the fixing component and the metal joint thereon stop rotating; subsequently, the production staff must drive the fourth electric push rod 33, the third electric push rod 29 and the second electric push rod 27 to retract, so that the polishing brush head 34 and the polishing belt 30 leave the metal joint and retract. When the polishing brush head 34 and the fourth electric push rod 33 are far away from the metal joint, the production staff can control the first driving motor 11 to drive the turntable thereon to rotate to turn out the polished metal joint from the polishing processing station and drive the next metal joint to be polished to the polishing processing station. The setting of multiple stations enables the production staff to disassemble the polished metal joint from the fixing component and install the metal joint to be polished when the equipment polishes a certain metal joint.

[0047] Embodiment 2:

[0048] Refer to Appendix Figure 4 、Appendix Figure 5 、Appendix Figure 9 and Appendix Figure 10, The fixing component includes a second connecting block 19 arranged at one end of the second support rod 16. An opening 20 is formed on one side of the second connecting block 19. A fixing sleeve 18 is fixedly arranged outside the side of the second connecting block 19 where the opening 20 is formed. A first electric push rod 17 is fixedly arranged inside the second connecting block 19. The output end of the first electric push rod 17 passes through the opening 20 and extends out of the second connecting block 19 until it is inside the fixing sleeve 18. A plurality of first fixing grooves 23 are arranged in an annular array on the side surface of the fixing sleeve 18. A plurality of connecting rods 21 are also hingedly arranged in each first fixing groove 23. One end of the connecting rod 21 extends outside the fixing sleeve 18 and is hingedly arranged with a third connecting block 25. The other end of the connecting rod 21 is connected to the output end of the first electric push rod 17 inside the fixing sleeve 18.

[0049] As a further embodiment, during the installation and fixing process, the production personnel can control the output end of the first electric push rod 17 to extend or retract to control the opening or retraction of the plurality of third connecting blocks 25 on the fixing component and the fixing block 26. Different positions where the output end of the first electric push rod 17 extends will affect the degree of opening between the third connecting block 25 and the fixing block 26, so as to meet the fixing requirements of metal joints with different inner wall sizes. The overall fixing component is a prior art, and this solution will not be elaborated too much.

[0050] Further, referring to the appendix Figure 5 , when the equipment is put into specific production, the production personnel can install the parts for production and processing to replace the fixing block 26 with relevant dimensions so that the fixing component can better fit the inner wall of the metal joint. Different fixing blocks 26 can adapt to the inner walls of metal joints with different sizes, playing a better fixing role, thus making the fixing of the metal joint more stable. The specific dimensions of the fixing block 26 refer to the specific requirements at the production site, and this solution does not have too many restrictions.
