Description

Technical Field

[0001] The invention relates to the technical field of thin-wall titanium tube polishing, in particular to a circumferential polishing device for the circumference of a thin-wall titanium tube. Background Art

[0002] As a new functional material, titanium tubes have the characteristics of high strength, high toughness, and fatigue resistance, so they have been widely used in many fields. For example, in the aerospace field, they are often used in the manufacture of aircraft engines, rockets, missiles and other equipment to reduce the weight of the equipment and improve flight efficiency. In the field of medical devices, they are used to manufacture dental implants, artificial joints, surgical instruments and other medical devices. In the chemical and petrochemical fields, titanium tubes are widely used to transport corrosive media such as acids, alkalis, and salts, as well as to manufacture various chemical equipment, because titanium has strong corrosion resistance. These equipment can withstand high temperatures, high pressures and corrosive environments to ensure the smooth progress of chemical production.

[0003] Since titanium is lighter than other conventional metals, the wall thickness of titanium tubes can be further reduced while ensuring the strength of the tube body, such as thin-walled titanium tubes. Thin-walled titanium tubes are processed the same as other metals. After processing, the surface needs to be polished to improve its surface quality. At present, the polishing of cylindrical tube metal is usually carried out by automatic polishing with a polishing machine. The specific structure is shown in the attached manual. Figure 1-2 As shown in the figure, the polishing wheels are symmetrically arranged. The cylindrical or tubular workpiece is placed in the gap between the polishing wheels. The polishing wheel rotates and drives the workpiece to move axially to complete the complete polishing operation of the workpiece surface. This polishing machine is usually used to polish cylindrical metals and thicker tubes. When polishing thin-walled titanium tubes, the downward gravity and the friction and extrusion of the polishing wheel ( Figure 4 As shown by the arrow in the middle), it will cause the thin-walled titanium tube to deform, such as Figure 4 The oval structure shown, and Figure 5 Therefore, it is difficult to polish thin-walled titanium tubes using polishing machines. Usually, the polishing operation is performed manually using a handheld polishing machine, such as Figure 6 As shown, it has the problems of heavy physical burden, long polishing cycle, and incomplete polishing. Summary of the invention

[0004] In view of the above-mentioned problems, the present invention aims to provide a circumferential polishing device for the circumference of a thin-walled titanium tube, which solves the problem that it is difficult to stably rotate the thin-walled titanium tube during manual polishing, and can achieve complete polishing of the circumference of the thin-walled titanium tube, solving the instability problem and the problem that the polishing quality cannot be effectively guaranteed when the current manual hand-held polishing machine is operated.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a circumferential polishing device for the circumferential surface of a thin-walled titanium tube, characterized in that: the circumferential polishing device includes a rotating clamping mechanism for clamping the thin-walled titanium tube and exposing the outer circumferential surface of the thin-walled titanium tube, and an equipment clamping mechanism that moves along the length direction of the thin-walled titanium tube and clamps the polishing device, and the equipment clamping mechanism can adjust the distance between the polishing device and the circumferential surface of the thin-walled titanium tube.

[0006] Preferably, the rotating clamping mechanism includes a base, with support plates symmetrically arranged at both ends of the base, and a conical column nested at the inner port of the thin-walled titanium tube is rotatably arranged on the inner side surface of each support plate, and one side of the support plate is slidably arranged on the base.

[0007] Preferably, the equipment clamping mechanism includes a gate-type bracket slidably arranged on the base parallel to the length direction of the thin-walled titanium tube, a card slot body of the sleeve polishing equipment is arranged on the top side of the gate-type bracket, and a fastening screw that can tighten the polishing equipment is passed through the side wall of the card slot body.

[0008] Preferably, an adjusting screw is vertically connected between the slot body and the door-shaped bracket.

[0009] The beneficial effect of the present invention is that the circumferential polishing device can realize stable clamping and rotation of thin-walled titanium tubes through the rotating clamping mechanism, solving the problem that it is difficult to stably realize the rotation of thin-walled titanium tubes during manual polishing. After the polishing device is further clamped by the device clamping mechanism, the circumference of the thin-walled titanium tube that is stably clamped and can rotate is completely polished, solving the instability problem and the problem that the polishing quality cannot be effectively guaranteed when the current manual handheld polishing machine is operated.

[0010] Furthermore, by adjusting the distance between the polishing device and the circumference of the thin-walled titanium tube, it is ensured that the polishing device can contact the circumference of the thin-walled titanium tubes with different diameters, thereby improving the applicability of the polishing device.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] See attached Figures 1 to 12 A thin-walled titanium tube circumferential polishing device is shown, which includes a rotating clamping mechanism for clamping the thin-walled titanium tube and exposing the outer circumferential surface of the thin-walled titanium tube, which can achieve stable clamping and rotation of the thin-walled titanium tube, solving the problem that it is difficult to stably rotate the thin-walled titanium tube during manual polishing. After the thin-walled titanium tube is clamped, its outer circumferential surface can be exposed, so that the polishing operation of the thin-walled titanium tube circumferential surface can be completely achieved when using the polishing equipment.

[0026] The circumferential polishing device also includes an equipment clamping mechanism that moves along the length direction of the thin-walled titanium tube and clamps the polishing equipment. The mechanism can stably clamp the currently used handheld polishing equipment. After clamping, the circumference of the thin-walled titanium tube that is stably clamped and rotatable can be completely polished, thereby solving the instability problem and the problem that the polishing quality cannot be effectively guaranteed when the current manual handheld polishing machine is operated.

[0027] In order to realize the polishing operation of thin-walled titanium tubes with different diameters, the clamping mechanism of the equipment can adjust the distance between the polishing equipment and the circumference of the thin-walled titanium tube, thereby ensuring that the polishing equipment can contact the circumference of thin-walled titanium tubes with different diameters, thereby improving the applicability of the polishing device.

[0028] Specifically, Figure 7-10 As shown, the rotating clamping mechanism includes a base 1, support plates 2 are symmetrically arranged at both ends of the base 1, and a conical column 3 is rotatably arranged on the inner side of each support plate 2 and is embedded in the inner port of the thin-walled titanium tube. Fig. 9 As shown, the two side ports of the thin-walled titanium tube are respectively sleeved on the conical column 3, and the conical column 3 can adapt to the positioning and clamping of different tube diameters, and after clamping, the thin-walled titanium tube can be driven to rotate axially by rotating the conical column 3. In order to allow the thin-walled titanium tube to rotate, a driving motor (not shown in the figure) connected to the conical column 3 can be provided on the outer wall of the support plate 2 on one side, and the titanium rod can be driven to rotate at a constant speed by the driving motor, and then the complete polishing along the length direction of the thin-walled titanium tube can be achieved through the polishing equipment assembled later.

[0029] In order to facilitate the quick clamping of thin-walled titanium tubes, Figure 8 As shown, the support plate 2 on one side is slidably arranged on the base 1, and preferably a slide rail connected to the support plate 2 is arranged on the base 1. When assembling the thin-walled titanium tube, the support plate 2 on this side is slid on the slide rail toward the outside of the base 1. After one end of the thin-walled titanium tube is clamped on the conical column 3 on the other side, the support plate 2 on this side is then driven to slide in the opposite direction on the slide rail, so that the conical column 3 on this side is nested in the port of the thin-walled titanium tube, and preferably a locking screw is created on the support plate 2 on this side. By rotating the locking screw so that its bottom end abuts against the surface of the slide rail, the clamping state of the support plate 2 on this side and the thin-walled titanium tube can be locked, thereby realizing the rapid clamping operation of the thin-walled titanium tube. After the subsequent polishing is completed, the locking screw is loosened and the support plate 2 is slid to quickly realize the disassembly of the thin-walled titanium tube.

[0030] Specifically, Figure 7-9 As shown, the equipment clamping mechanism includes a gate-shaped bracket 4 slidably arranged on the base 1 parallel to the length direction of the thin-walled titanium tube (it is also preferred to arrange a slide rail on the base 1 to drive the gate-shaped bracket 4 to slide), a clamping groove body 5 of the sleeve polishing equipment is arranged on the top side of the gate-shaped bracket 4, and a fastening screw 51 that can tighten the polishing equipment is passed through the side wall of the clamping groove body 5. Fig. 9As shown, after the above-mentioned rapid assembly of the thin-walled titanium tube, the handheld polishing device is inserted into the slot body 5, and the polishing head of the polishing device is made to contact the surface of the thin-walled titanium tube, and then the polishing head is made to contact the outer wall of the polishing device through the fastening screw 51, so that the polishing device can be firmly clamped. Then, the polishing device is slid from one end of the thin-walled titanium tube to the other end through the gate-shaped bracket 4. The thin-walled titanium tube is driven to rotate at a uniform speed by a driving motor, so that the complete polishing operation of the outer peripheral surface of the thin-walled titanium tube can be achieved.

[0031] In order to achieve the adjustment of thin-walled titanium tubes with different diameters, such as Fig.11 As shown, an adjusting screw 6 is vertically connected between the slot body 5 and the gate-type bracket 4. After the polishing equipment is fastened and assembled in the slot body 5, the adjusting screw 6 is vertically adjusted according to the abutment between the polishing head and the surface of the thin-walled titanium tube. After the adjustment, the slot body 5 is locked by locking the nuts on the upper and lower sides of the gate-type bracket 4, and then the gate-type bracket 4 can be slid to perform the polishing operation of the thin-walled titanium tube.

[0032] The principle of the present invention is: when the annular polishing device is in use, the support plate 2 is slid on the slide rail toward the outside of the base 1. After one end of the thin-walled titanium tube is clamped on the conical column 3 on the other side, the support plate 2 on this side is driven to slide in the opposite direction on the slide rail, so that the conical column 3 on this side is nested in the port of the thin-walled titanium tube. By rotating the locking screw so that its bottom end is against the surface of the slide rail, the clamping state of the support plate 2 and the thin-walled titanium tube on this side can be locked, thereby realizing the rapid clamping operation of the thin-walled titanium tube.

[0033] Then, the handheld polishing device is inserted into the slot body 5, and the polishing head of the polishing device is made to contact the surface of the thin-walled titanium tube. After that, the polishing head is made to contact the outer wall of the polishing device through the fastening screw 51, so that the polishing device can be firmly clamped. Then, the polishing device is slid from one end of the thin-walled titanium tube to the other end through the gate-shaped bracket 4. The thin-walled titanium tube is driven to rotate at a uniform speed by a driving motor, so that a complete polishing operation of the outer peripheral surface of the thin-walled titanium tube can be achieved.

[0034] After the subsequent polishing is completed, the locking screw is loosened and the support plate 2 is slid to quickly disassemble the thin-walled titanium tube.

[0035] The above shows and describes the basic principle, main features and advantages of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention claimed.
