Description

Technical Field

[0002] Titanium rod grinding is an important process in the field of titanium processing, mainly used to improve the surface roughness, precision or appearance of titanium rods. Titanium rod grinding means grinding the surface of titanium metal rods with circular, square, polygonal, etc. cross-sections to remove surface cracks. The existing grinding methods include manual grinding, where one end of an electric grinder is hoisted using a sling and an operator manually operates the grinder wheel to contact and grind the titanium rod; robotic grinding, where a grinding device is installed at the end of the robot and visual tracking grinding is carried out; and special equipment grinding, where the titanium rod is placed in a workpiece slot and the grinding wheel automatically contacts and grinds it.

[0003] In the use of titanium rod grinding equipment on the market, since the grinding pressure of the grinding wheel exceeds 300 kg, the grinding wheel is prone to bursting. During manual grinding, there are safety risks for the operating workers; at the same time, the working intensity is high, the grinding time is long, the grinding equipment is heavy in weight, the grinding load is large, and manual operation results in a high labor intensity and large vibration. During robotic grinding, the equipment has large vibration, and the grinding pressure and grinding depth are limited; it cannot be applied to grinding titanium rods with different cross-sections. Special equipment grinding can only be applied to grinding one specification among circular, square, and polygonal. Therefore, we propose a titanium rod grinding device. Summary of the Invention

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-6 , the present invention provides a technical solution: a titanium rod grinding device, including a ground rail 1, a crawler-type walking vehicle 2, a negative pressure dust removal system 3, a tilter 5 and a slide table 8. A plurality of walking shafts 4 are slidably connected to the upper end of the ground rail 1. A crawler-type walking vehicle 2 is distributed on one side of the ground rail 1, and a negative pressure dust removal system 3 for negative pressure dust collection is distributed on the side of the ground rail 1 away from the crawler-type walking vehicle 2. A servo lifting mechanism 6 is erected on the upper end of the right walking shaft 4, and a tilter 5 is erected at the front end of the servo lifting mechanism 6. A tilter 5 is erected at one end of the tilter 5 away from the servo lifting mechanism 6, and a hydraulic cylinder clamping mechanism 7 is erected at the other end of the tilter 5. A slide table 8 is slidably connected to the upper end of the left walking shaft 4, and a right clamping arm 9 is slidably connected to the upper end of the slide table 8. A hydraulic manipulator 10 is erected at the output end of the crawler-type walking vehicle 2, and an elastic grinding mechanism 11 is erected at the end of the hydraulic manipulator 10 away from the crawler-type walking vehicle 2. A hydraulic motor 12 is erected at the lower end of the elastic grinding mechanism 11, and a grinding wheel 13 is key-connected to the power output end of the hydraulic motor 12. The hydraulic manipulator 10 serves as a power arm and is connected to the grinding system composed of the hydraulic motor 12 and the grinding wheel 13. Its power arm can be adjusted multi-angularly and omnidirectionally according to the use requirements to meet the use requirements of the grinding system, which brings convenience to the subsequent grinding of titanium rods. At the same time, using the crawler-type walking vehicle 2 as the driving implementation can avoid the safety risks brought by manual grinding, and at the same time, this kind of grinding also isolates the harm of dust to the human body.

[0024] A slider 901 is fixed to the inner wall of the right clamping arm 9, and a slide rail 902 is slidably connected to the inner wall of the slider 901. The slide rail 902 is fixed to the slide table 8. Left clamping arms 903 are symmetrically distributed along the center of the slide rail 902 on the right clamping arm 9, and a slider 901 is also fixed to the inner wall of the left clamping arm 903. An active gear 905 is arranged directly below the slide rail 902, and a pair of racks 904 are symmetrically distributed on both sides of the outer wall of the active gear 905. The upper rack 904 is fixed to the right clamping arm 9, and the lower rack 904 is fixed to the left clamping arm 903. A hydraulic rod 906 is bolted to the lower end of the left clamping arm 903. The right clamping arm 9, the slider 901, the slide rail 902, the left clamping arm 903, the rack 904, the active gear 905, and the hydraulic rod 906 form a clamping and translation mechanism. And the clamping and translation mechanism clamps a titanium rod. The clamping and translation mechanism uses the hydraulic rod 906 as a power source. Its rack 904 and active gear 905 synchronously drive the right clamping arm 9 and the left clamping arm 903 to clamp and move, which can meet the clamping requirements for the titanium rod. The slider 901 and the slide rail 902 are used as sliding parts to reduce the moving friction of the clamping arm and improve the action sensitivity of the clamping arm. At the same time, the clamping width of this kind of clamping and translation mechanism is an adjustable structure, which can meet the user's need to appropriately adjust according to different sizes of the titanium rod, and improve the applicable range of the equipment.

[0025] The elastic grinding mechanism 11 includes a telescopic cylinder 1101 and a rectangular spring 1102. The rectangular spring 1102 is connected to the outer wall of the telescopic cylinder 1101. The short rod of the telescopic cylinder 1101 is connected to the hydraulic motor 12, and the long rod of the telescopic cylinder 1101 is connected to the hydraulic robotic arm 10. The elastic grinding mechanism 11 serves as a buffer protection component of the grinding system. During the grinding process, when the grinding wheel 13 contacts the titanium rod, high-frequency vibration and instantaneous impact will be generated. The elastic grinding mechanism 11 can absorb energy through its own deformation, reducing the transmission of vibration to the grinding system and the hydraulic robotic arm 10. At the same time, when grinding a titanium rod with a curved surface or an irregular surface, the elastic grinding mechanism 11 maintains a constant pressure through elastic deformation to ensure uniform grinding. And when there is rigid contact, the flexible characteristics of the buffer component can provide a buffer space to protect the surface quality of the titanium rod.

[0026] Working principle: For this type of titanium rod grinding device, first, the titanium rod to be ground is placed on the clamping and translation mechanism by a forklift. At this time, the hydraulic rod 906 on the clamping and translation mechanism contracts, driving the two racks 904 to move synchronously. Its right clamping arm 9 and left clamping arm 903 move synchronously to fixedly clamp the titanium rod. Its slider 901 and slide rail 902 reduce the friction of the right clamping arm 9 and left clamping arm 903 during movement. Subsequently, the hydraulic manipulator 10 on the crawler vehicle 2 drives the elastic grinding mechanism 11 close to the surface of the titanium rod. Its hydraulic motor 12 drives the grinding wheel 13 to rotate to grind the surface of the titanium rod. The elastic grinding mechanism 11 can absorb energy through its own deformation, reducing the transmission of vibration to the grinding system and the hydraulic manipulator 10. The operator performs grinding based on the real-time state captured by the monitoring camera. After grinding one side, the crawler vehicle 2 retreats, the clamping and translation mechanism releases the clamping arm, the hydraulic cylinder clamping mechanism 7 clamps, the servo lifting mechanism 6 lifts, the rotary machine 5 rotates the titanium rod to another side, places it on the clamping and translation mechanism, and repeats the grinding operation until all sides are ground.
