Description

Technical Field

[0001] The present application relates to the field of polishing equipment, and in particular to a sizing sleeve polishing device for a flexible composite pipe. Background Art

[0002] The sizing sleeve is a device used for sizing flexible composite pipes, usually composed of a sizing sleeve, a connecting flange, a water jacket and a water ring body. Its main function is to shape and cool the flexible composite pipe so that the flexible composite pipe reaches the specified diameter and shape, thereby ensuring the quality and accuracy of the pipe. During the cooling and shaping process of the flexible composite pipe, the sizing sleeve directly uses tap water for cooling. After long-term use, calcification precipitation will form on the inner and outer diameter surfaces of the sizing sleeve, resulting in scratches on the outer diameter surface of the composite pipe, affecting product quality and even causing failure to meet the standards. Therefore, the sizing sleeve needs to be polished and polished regularly.

[0003] In the related art, manual grinding is generally performed, that is, workers put their arms into the sizing sleeve and use sandpaper to grind the calcified deposits on the inner wall of the sizing sleeve, or wrap sandpaper around a wooden stick and then put it into the sizing sleeve to grind back and forth. Manual grinding has problems such as difficult operation, uneven grinding, enlargement of the inner diameter of the sizing sleeve, increased production costs, and composite pipes that do not meet standard requirements.

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The present application embodiment discloses a sizing sleeve polishing device for a flexible composite pipe. Figure 1 A sizing sleeve polishing device for a flexible composite pipe includes a lathe body 1, a limiting component 2 and a polishing component 3.

[0027] Reference Figure 1 A three-jaw chuck 11 for driving the sizing sleeve to rotate is provided on the head of the lathe body 1. During polishing and grinding, the sizing sleeve is clamped by the three-jaw chuck 11.

[0028] Reference Figure 1and Figure 2 The limit assembly 2 is located on the lathe body 1. The limit assembly 2 includes a sliding base 21, a limit ring 22 and a limit bolt 23. The sliding base 21 is slidably connected to the lathe body 1. The sliding direction of the sliding base 21 is parallel to the axial direction of the sizing sleeve. The limit ring 22 is fixedly connected to the upper surface of the sliding base 21. There are multiple limit bolts 23. In this embodiment, there are three limit bolts 23. The three limit bolts 23 are evenly distributed along the circumferential direction of the limit ring 22. The limit bolt 23 is threadedly connected to the limit ring 22 and one end extends into the limit ring 22. One end of the limit bolt 23 extending into the limit ring 22 is rotatably connected to a clamping roller 231. During grinding, after the three-jaw chuck 11 fixes the sizing sleeve, one end of the sizing sleeve is inserted into the limit ring 22, and then the limit bolt 23 is rotated so that the clamping roller 231 at the end of the limit bolt 23 is pressed against the sizing sleeve. The sliding base 21 that is slidably arranged can be suitable for sizing sleeves of different lengths, thereby further enhancing the applicability of the limiting device.

[0029] Reference Figure 1 The polishing assembly 3 includes a base 31, a feed member 32, a mounting seat 33, an adjusting member 34 and a polishing rod 35. A guide rail 12 is integrally welded to the lathe body 1. The cross section of the guide rail 12 is trapezoidal. The base 31 is slidably connected to the guide rail 12. The sliding direction of the base 31 is parallel to the axis of the sizing sleeve. The end of the guide rail 12 away from the sizing sleeve is threadedly connected to a limiting column 13. The limiting column 13 can prevent the base 31 from derailing from the guide rail 12, thereby ensuring the stability of the base 31.

[0030] Reference Figure 1 The feeding member 32 includes a driving motor, a driving gear 322 and a rack 323. The rack 323 is fixedly connected to the side wall of the lathe body 1. The length direction of the rack 323 is parallel to the sliding direction of the base 31. The housing of the driving motor is fixedly connected to the side wall of the base 31. The driving gear 322 is coaxially fixedly connected to the output shaft of the driving motor, and the driving gear 322 and the rack 323 are meshed.

[0031] Reference Figure 1 and Figure 3 The upper surface of the base 31 is provided with a slide groove, and a slider is integrally connected to the bottom of the mounting seat 33. The mounting seat 33 is slidably connected to the slide groove through the slider, and the sliding direction of the mounting seat 33 is perpendicular to the sliding direction of the base 31. The adjusting member 34 includes an adjusting screw rod 341 and a hand wheel 342. The adjusting screw rod 341 is located in the slide groove, and the end of the adjusting screw rod 341 is rotatably connected to the end wall of the slide groove. One end of the adjusting screw rod 341 extends out of the slide groove, and the hand wheel 342 is coaxially fixedly connected to the end of the adjusting screw rod 341 extending out of the slide groove.

[0032] Reference Figure 1 and Figure 4, slots 331 for fixing the grinding rod 35 are provided on both sides of the mounting seat 33, and three fixing bolts 332 are threadedly connected to the mounting seat 33. The fixing bolts 332 are vertically arranged, and one end of the fixing bolts 332 extends into the slot 331. One end of the grinding rod 35 is arranged in a square shape, and the square end of the grinding rod 35 is located in the slot 331. The fixing bolts 332 extend into the slot 331 to press the grinding rod 35 and the slot 331 tightly.

[0033] The implementation principle of a sizing sleeve polishing device for a flexible composite pipe in an embodiment of the present application is as follows: when the sizing sleeve needs to be polished, the sizing sleeve is first installed on a lathe. During installation, one end of the sizing sleeve is clamped and fixed using a three-jaw chuck 11 on the machine head, and then the position of the limiting assembly 2 is adjusted according to the length of the sizing sleeve. During adjustment, the sliding base 21 is pushed to slide so that the end of the sizing sleeve is located in the limiting ring 22, and then the three limiting bolts 23 are rotated at the same time so that the clamping roller 231 at the end of the limiting bolt 23 is pressed against the outer wall of the sizing sleeve, thereby achieving clamping and fixing of the sizing sleeve.

[0034] After the fixation is completed, the driving motor drives the driving gear 322 to rotate, thereby driving the base 31 to slide toward the direction close to the sizing sleeve, so that the grinding rod 35 is inserted into the sizing sleeve, and then the position of the grinding rod 35 is adjusted. When adjusting, the hand wheel 342 is turned, and the hand wheel 342 drives the adjusting screw 341 to rotate. Due to the guiding effect of the slider and the slide groove, the adjusting screw 341 can drive the mounting seat 33 to slide left and right when it rotates, thereby driving the grinding rod 35 to move horizontally until the grinding rod 35 contacts the inner wall of the sizing sleeve. Then the lathe body 1 can be turned on to drive the sizing sleeve to rotate, thereby achieving grinding and polishing of the inner wall of the sizing sleeve.

[0035] When the grinding rod 35 needs to be replaced, the fixing bolt 332 is rotated to loosen the grinding rod 35, and then one end of the new grinding rod 35 is inserted into the slot 331, and then the fixing bolt 332 is rotated to extend one end of the fixing bolt 332 into the slot 331 to tighten the grinding rod 35.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
