Description

Technical Field

[0001] The utility model belongs to the technical field of diamond wire saw grinding, and mainly relates to a diamond tool grinder. Background Art

[0002] Diamond tools refer to a type of tool products that use diamond particles or powder as the main element. This type of tool includes: cutting, grinding, drilling, milling, and polishing. The diamond tool described in this application is a diamond wire saw. A diamond wire saw refers to a method of fixing diamond abrasives on a metal wire using an electroplating process or a resin bonding method. Different from the previous mortar cutting technology, diamond wire saw cutting uses multi-wire cutting technology. This technology has strong cutting ability and high efficiency. The wire diameter size of the diamond wire saw is strictly controlled, the cutting loss of the cutting material is very small, and the cut product has a high precision. Since no mortar is used, the working environment is clean, and it is an energy-saving and environmentally friendly product. After the diamond is fixed to the steel wire, it is necessary to grind off the loosely attached or uneven diamonds to ensure product quality.

[0003] The patent application document with publication number CN112571248A discloses a diamond wire saw grinding device. In order to solve the problem that the diamond wire saw deviates during the production process and is broken by the grinding stone clamp due to deformation, and needs to be frequently stopped for repair, the patent sets an auxiliary component, and sets a number of parallel loops on the auxiliary component, which are diamond wire saws. The several loops set on the auxiliary component are synchronously polished with the diamond wire saw, and the end face of the grinding stone is synchronously polished, which avoids the phenomenon that the groove deforms and breaks the diamond wire saw clamp, ensures product quality, avoids wire breakage and shutdown, and increases production efficiency.

[0004] However, when several loops are actually set, there will always be gaps between the loops and between the loops and the diamond wire saw. When several loops are polished synchronously with the diamond wire saw, grooves will still appear on the grindstone, causing the grooves to deform and break the diamond wire saw clamp. Therefore, this patent still does not solve the problem that grooves will appear on the grindstone and the grooves will deform and break the diamond wire saw clamp. Utility Model Content

The driving motor 2 drives the third swing arm 26 to rotate, thereby driving the first swing arm 18 to rotate, and then the first swing arm 18 drives the second swing arm 22 to rotate.

[0036] Specifically, a mounting plate 28 is fixedly mounted on the base 1, and one end of the mounting frame 15 is fixedly mounted on the mounting plate 28, that is, the mounting frame 15 is fixedly mounted on the base 1 through the mounting plate 28, and the mounting frame 15 serves as a base for mounting the first swing arm 18, the second swing arm 22, and the third swing arm 26.

[0039] The third mounting seat 24 is fixedly mounted on the mounting plate 28, and a second rotating pin 25 with an axis extending in the up-down direction is rotatably mounted on the third mounting seat 24. A third swing arm 26 is fixedly mounted on the second rotating pin 25, and the rotating shaft of the driving motor 2 is connected to one end of the third swing arm 26 through the second rotating pin 25, so that the third swing arm 26 can rotate around the axis of the second rotating pin 25. At the same time, a second slide post 27 is fixedly mounted on the other end of the third swing arm 26, and the second slide post 27 is located in the waist-shaped groove 19 and slides therein.

[0040] The rotating shaft of the driving motor 2 rotates, and the grinding stone 5 can swing back and forth around the axis of the transmission shaft 21 through the transmission of the first swing arm 18, the second swing arm 22 and the third swing arm 26, so as to avoid the diamond wire saw 11 from continuously grinding at the same position, thereby avoiding the formation of grooves and preventing the diamond wire saw 11 from being clamped and deformed by the grooves.

[0041] The axes of the first rotating pin 17, the second rotating pin 25 and the transmission shaft 21 are located in the same vertical plane, and the transmission shaft 21 is located between the first rotating pin 17 and the second rotating pin 25.

[0045] The auxiliary component 6 includes a loop wire 14, and the material of the loop wire 14 is a diamond wire saw. When a single diamond wire saw 11 is ground on the grindstone 5, it is easy to grind a groove on the lower end of the grindstone 5. As the groove continues to deepen, the outer periphery of the diamond wire saw 11 is clamped on both sides of the groove, which is easy to deform or even break the diamond wire saw 11. By setting a plurality of loop wires 14 on the auxiliary component 6 and grinding synchronously with the diamond wire saw 11, the end face of the grindstone 5 is also ground synchronously, avoiding the phenomenon that the groove deforms or breaks the diamond wire saw 11, thereby ensuring product quality, avoiding wire breakage and shutdown, and increasing production efficiency.

[0046] At the same time, because dust will be generated during grinding, the dust may enter the drive motor 2, so in the present application, the drive motor 2 is staggered from the grinding position, which avoids damage to the drive motor 2 to a certain extent.
