Description

[0001] This invention patent application is a divisional application of Chinese Patent Application No. 202110103743.1. The original application had the application number 202110103743.1 and the application date was January 26, 2021. The invention is entitled "Diamond Particle Feeding Device for Diamond Tools and Method for Preparing Diamond Tools". Technical Field

[0002] This invention relates to a device for the manufacture of diamond tools, and more particularly to a device for orderly and uniformly distributing diamond particles. Background Technology

[0003] Diamond cutting tools are characterized by high cutting speed, high cutting accuracy, and low rotational inertia; they can effectively reduce the occurrence of chipping, notching, and cracking in products. However, defects such as uneven diamond particle distribution and high porosity of the tool can easily lead to unstable cutting performance, low machining accuracy, and failure phenomena such as chipping and breakage. In the current sintering process for manufacturing ultra-thin diamond cutting tools, the mixing, weighing, loading, and spreading of powder materials are all done manually. Due to the instability of manual operation, the mixed materials cannot achieve uniform and consistent distribution in the mold during the material spreading process. In particular, the current diamond particle spreading method uses a flat... The plate has multiple orderly arranged slots for holding diamond particles. The operator spreads the diamond particles into the slots of the plate and vibrates the plate to ensure that each slot contains diamond particles. Excess diamond particles are then swept away. The diamond particles can be arranged in an orderly manner according to the orderly arrangement of the slots and evenly distributed on the diamond matrix layer, thus completing the orderly and uniform arrangement of diamond particles in the diamond tool. However, this method of diamond particle distribution is relatively cumbersome, and repeated distribution operations by the operator can easily lead to problems such as partial leakage and excess distribution, resulting in low work efficiency and poor and uneven distribution effect.

The needle tips 221 contact the diamond particles or sink into the diamond particles, and the negative pressure gas is connected so that the needle tips 221 pick up the diamond particles.

[0065] The advantages of the diamond particle feeding device of this invention compared with the prior art are as follows: This invention can drive the first driving cylinder 3 to push the diamond particle feeding mechanism 2 towards the material tray 1, the needle 221 contacts or enters the diamond particles, and connects the negative pressure gas so that the needle 221 can pick up the diamond particles; then the diamond particle feeding mechanism with picked up the diamond particles is moved above the diamond matrix layer, and the negative pressure gas is cut off, and the diamond particles are orderly laid on the diamond matrix layer; This invention can automatically and evenly arrange diamond particles on the diamond matrix layer, which can improve work efficiency and save labor costs; and each The needle 22 picks up a diamond particle, preventing the diamond particles from piling up or leaving gaps in the fabric, thus improving the uniformity of the diamond particle distribution and reducing production costs.

The first cylinder seat 31 is fixed on a side plate 41, and one end of the first cylinder push rod 32 is fixed on a fixed plate 23. The diamond particle feeding mechanism 2 is disposed on the fixed plate 23. The first driving cylinder 3 can push the diamond feeding mechanism 2 back and forth above the material tray 1, so that the diamond feeding mechanism 2 can pick up diamond particles from the material tray 1.

[0067] The locking plate 21 of the present invention is disposed above the fixing plate 23, and a needle tube cover plate 24 is disposed below the fixing plate 23. The fixing plate 23 is provided with a rectangular through hole 231 for the needle tube 22 to pass through, and the needle tube cover plate 24 is provided with a plurality of through holes 241 for each needle tube 22 to pass through. When the diamond particle feeding mechanism 1 moves downward, the needle tube cover plate 24 also moves downward and can abut against the material tray 1. The needle tube 22 passes through the needle tube cover plate 24 to ensure that all needle tubes 22 can extend into the material tray 1 to pick up diamond particles, and the feeding is more accurate and stable.

[0068] A clamping plate 25 is provided between the fixing plate 23 and the needle tube cover plate 24 of the present invention, and the clamping plate 25 is provided with a rectangular through hole 251 corresponding to the rectangular through hole 231.

[0069] The diamond particle feeding mechanism 2 of the present invention also has a fixing frame 26, which has a first horizontal plate 261, a second horizontal plate 262, and a first vertical plate 263 connecting the first horizontal plate 261 and the second horizontal plate 262; the arranging locking plate 21 is disposed below the first horizontal plate 261, and a venting clamping plate 27 and a venting partition 28 are sandwiched between the first horizontal plate 261 and the arranging locking plate 21.

The diamond particle fabric distribution device for ordered fabric distribution as described in claim 1, characterized in that: It also includes a lateral movement mechanism that drives the diamond particle laying mechanism to move laterally and orderly lay diamond particles on the diamond matrix layer. The lateral movement mechanism has a lateral slide bar, a slider disposed on one side of the side plate, and a fifth drive cylinder that pushes the diamond particle laying mechanism to move laterally back and forth.

4. The diamond particle fabric distribution device for ordered fabric distribution as described in claim 1, characterized in that: The material tray includes an inner tray for holding diamond particles and an outer tray surrounding the inner tray. The outer walls at both ends of the inner tray have fins with locking holes. The bottom plate of the outer tray has screw holes corresponding to the locking holes, and two bolts pass through the locking holes to lock the inner tray within the screw holes. A vibrator is located below the outer tray. Extension plates with through holes are located on both sides of the outer tray. A vibrating plate is arranged parallel to the outer tray below it, and a locking hole is provided on the vibrating plate corresponding to the through hole. The outer tray is locked to the vibrating plate by guide bolts passing through the through holes and secured in the locking holes. A spring is fitted onto the guide bolt, with one end of the spring abutting the bottom surface of the outer tray and the other end abutting the top surface of the vibrating plate.

5. The diamond particle fabric distribution device for ordered fabric distribution as described in claim 4, characterized in that: The material tray also includes a support base, and a fourth drive cylinder is provided between the support base and the outer plate to drive the outer plate to move up and down. The fourth drive cylinder has a fourth cylinder seat fixed to the side of the support base and a fourth cylinder push rod connected to the bottom surface of the vibrating plate.
