Description

Technical Field

[0001] The utility model relates to the technical field of tungsten - copper alloy processing, in particular to a grinding tooling for tungsten - copper alloy. Background Technique

[0002] Tungsten - copper alloy is an excellent micro - electronic packaging material, a pseudo - alloy composed of two immiscible metals, tungsten and copper. When applied to the micro - electronic field, tungsten - copper alloy parts require both good surface roughness and flatness, and very strict appearance quality. Therefore, grinding processes are often used for tungsten - copper alloy parts to meet these requirements.

[0003] The existing grinding tooling for tungsten - copper alloy is usually only used for clamping and fixing tungsten - copper alloy plates, and then the alloy plates are ground by grinding equipment. When double - side grinding of tungsten - copper alloy plates is required, they need to be disassembled, and then the tungsten - copper alloy is flipped and fixed again. Therefore, the operation process is cumbersome and the processing efficiency is reduced. Therefore, it is urgent to solve such problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a grinding tooling for tungsten - copper alloy.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

On the mutually - approaching surfaces of the two first mounting plates, there are fixed mechanisms for fixing alloy plates. On both sides of the top of the base, there are alignment mechanisms for aligning alloy plates. At the bottom of the mutually - approaching surfaces of the two first mounting plates, there is a flipping mechanism for flipping alloy plates;

[0007] The flipping mechanism includes second fixing blocks fixed at the bottom of the mutually - approaching surfaces of the two first mounting plates. At both sides of the top of the two second fixing blocks, mutually - communicating first trapezoidal chutes are opened. Inside the first trapezoidal chutes, first trapezoidal sliders are slidably arranged. On the top of the two first trapezoidal sliders, first fixing blocks are fixed. On the top of the first fixing block, a first slot is opened. At the bottom of the inner wall of the first slot, a plurality of springs are fixed. The tops of the plurality of springs are fixed to the same pressing plate. On the top of the pressing plate, a rack is fixed.

[0008] As a further solution of the utility model, the fixing mechanism comprises two rotating shafts, and the two rotating shafts are respectively rotatably connected to the outer wall of one end of the first mounting plate. On the mutually approaching surfaces of the two rotating shafts, U-shaped mounting plates are fixed. Threaded holes are formed in the tops of the U-shaped mounting plates, and a threaded rod adapted thereto is rotatably connected in the threaded holes. A pressing plate is arranged at the bottom of the threaded rod, and the threaded rod is rotatably connected to the top of the pressing plate. Rotating the threaded rod can drive the pressing plate to clamp both ends of the alloy plate. The staff can process the alloy plate by holding a grinding device.

[0009] As a further solution of the utility model, two symmetric second trapezoidal chutes are formed in the inner wall of the U-shaped mounting plate, and second trapezoidal sliders adapted thereto are slidably arranged in the second trapezoidal chutes, and the second trapezoidal sliders are fixed to one end of the pressing plate.

[0010] As a further solution of the utility model, second rubber pads are mounted at the bottoms of the two pressing plates.

[0011] As a further solution of the utility model, gears are fixed to the outer walls of the two rotating shafts, and the gears are meshed with a rack. The number of teeth of the rack and the gears are mutually adapted, and the rack can drive the gears to rotate so as to turn over the alloy plate.

[0012] As a further solution of the utility model, the alignment mechanism comprises second mounting plates fixed to both sides of the top of the base. Electric push rods are mounted on the mutually remote surfaces of the two second mounting plates. The output shafts of the electric push rods pass through one side of the second mounting plates and are fixed with U-shaped positioning plates. First rubber pads are mounted on the mutually approaching inner walls of the two U-shaped positioning plates. L-shaped connecting rods are fixed to both ends of the bottom of one of the U-shaped positioning plates, and the other ends of the two L-shaped connecting rods are respectively fixed to one side of the first fixing block.

[0013] As a further solution of the utility model, the surface of the rack remote from the second mounting plate is arc-shaped. When the rack approaches the gear, the gear will press down on the arc surface of the rack. When the rack resets, the rack will be meshed with the gear to drive the gear to rotate.

[0025] The flipping mechanism includes second fixing blocks 206 fixed at the bottom of the mutually approaching surfaces of the two first mounting plates 101. At both sides of the top of the two second fixing blocks 206, mutually communicating first trapezoidal chutes 212 are opened. Inside the first trapezoidal chutes 212, first trapezoidal sliders 207 are slidably arranged. At the top of the two first trapezoidal sliders 207, first fixing blocks 205 are fixed. At the top of the first fixing block 205, a first notch 208 is opened. At the bottom of the inner wall of the first notch 208, a plurality of springs 210 are fixed. At the top of the plurality of springs 210, the same pressing plate 209 is fixed. At the top of the pressing plate 209, a rack 211 is fixed.

[0026] In this embodiment, the fixing mechanism includes two rotating shafts 3, and the two rotating shafts 3 are respectively rotatably connected to the outer walls of one ends of the first mounting plates 101. On the mutually approaching surfaces of the two rotating shafts 3, U-shaped mounting plates 302 are fixed. At the top of the U-shaped mounting plate 302, a threaded hole is opened, and a matching threaded rod 304 is rotatably connected in the threaded hole. At the bottom of the threaded rod 304, there is a pressing plate 303, and the threaded rod 304 is rotatably connected to the top of the pressing plate 303. Rotating the threaded rod 304 can drive the pressing plate 303 to clamp and fix both ends of the alloy plate, and the staff can process the alloy plate by holding a grinding device.

[0027] In this embodiment, two symmetric second trapezoidal chutes 306 are opened on the inner wall of the U-shaped mounting plate 302, and matching second trapezoidal sliders are slidably arranged in the second trapezoidal chutes 306, and the second trapezoidal sliders are fixed to one end of the pressing plate 303.

[0028] In this embodiment, second rubber pads 305 are installed at the bottoms of the two pressing plates 303.

[0029] In this embodiment, gears 301 are fixed on the outer walls of the two rotating shafts 3, and the gears 301 are meshed with the rack 211, and the number of teeth of the rack 211 and the gears 301 are mutually adapted, and can drive the gears 301 to rotate and then flip the alloy plate.

[0030] In this embodiment, the alignment mechanism includes second mounting plates 2 fixed to both sides of the top of the base 1. Electric push rods 201 are mounted on the sides of the two second mounting plates 2 facing away from each other. Output shafts of the electric push rods 201 pass through one side of the second mounting plates 2 and are both fixed with U-shaped positioning plates 202. First rubber pads 203 are mounted on the inner walls of the two U-shaped positioning plates 202 facing each other. At both ends of the bottom of one of the U-shaped positioning plates 202, L-shaped connecting rods 204 are fixed. The other ends of the two L-shaped connecting rods 204 are respectively fixed to one side of the first fixing block 205.

[0031] In this embodiment, the surface of the rack 211 away from the second mounting plate 2 is arc-shaped. When the rack 211 approaches the gear 301, the gear 301 will press down on the arc surface of the rack 211. When the rack 211 resets, the rack 211 will engage with the gear 301 to drive the gear 301 to rotate.

[0032] Working principle: During use, first place both ends of the alloy plate to be ground on the top of the inner walls of the two U-shaped mounting plates 302. Then, by operating the electric push rod 201, the electric push rod 201 will push the U-shaped positioning plate 202 close to both sides of the alloy plate and align it. The first rubber pad 203 will prevent damage to the alloy plate during the alignment process. When one of the U-shaped positioning plates 202 moves, it will drive the first fixing block 205 to move through the L-shaped connecting rod 204. The first fixing block 205 will drive the first trapezoidal slider 207 to slide in the first trapezoidal chute 212. When the first fixing block 205 drives the rack 211 to contact the gear 301, the gear 301 will contact the arc surface of the rack 211. At this time, the gear 301 will squeeze the rack 211, and the rack 211 will squeeze the extrusion plate 209, and the extrusion plate 209 will squeeze the spring 210. After the alignment is completed, by rotating the threaded rod 304, the threaded rod 304 will drive the pressing plate 303 close to the top of the alloy plate and press it. At this time, the staff can grind the alloy plate with a hand-held grinding device. After the treatment is completed, operate the electric push rod 201 to reset the U-shaped positioning plate 202. At this time, the end of the rack 211 away from the arc surface will engage with the gear 301 and drive the gear 301 to rotate, thereby rotating the gear 301 by 180 degrees, driving the rotating shaft 3 to rotate, and driving the alloy plate to automatically flip.
