Description

Technical Field

[0001] The utility model relates to the technical field of diamond coring drill manufacturing, in particular to a diamond coring drill coating blanking compacting device. Background Art

[0002] The diamond abrasive grains of traditional electroplated diamond core drills are unevenly distributed, which easily leads to agglomeration of abrasive grains, and the exposed height of diamonds is inconsistent. When drilling hard rock formations at high speed, the diamond abrasive cluster area in the drill teeth will bear a greater load, causing stress concentration in the softer electroplating layer and its bonding surface with the diamond abrasive grains. During the periodic, high-speed and frequent drilling process of the drill teeth, stress continues to accumulate and eventually causes the diamond abrasive grains to fall off from the electroplating layer, causing the diamond abrasive grains to lose their cutting performance, thereby reducing the service life of the diamond core drill.

[0028] Figure 2 It is a cross-sectional view of the diamond spreading mechanism. DETAILED DESCRIPTION

[0029] like Figure 1-2 As shown, the diamond coring drill coating blanking compacting device of the utility model comprises a frame and an electric control system, on which a workpiece storage box 9, a composite glue pool 13, a first clamp 11, a conveyor belt 16, a second clamp 6 and a finished product box 5 are arranged in sequence.

[0030] The core drill to be processed is placed in the workpiece storage box 9.

[0031] The first fixture 11 is fixed on the rotator 10 at an angle of 60 degrees, and the rotator 10 drives the first fixture 11 to rotate. The rotator 10 adopts a blade-type swing cylinder. The rotator 10 drives the workpiece (coring drill) to rotate within 360 degrees, so that all surfaces of the workpiece can be covered by the diamond scattering mechanism.

[0032] A diamond spreading mechanism 7 capable of lifting and lowering is provided directly above the first fixture 11. The lifting and lowering of the entire diamond spreading mechanism 7 can be achieved by means of a standard cylinder or a screw nut pair or other driving structure. Specifically, the diamond spreading mechanism 7 includes a cylinder 71, a diamond storage chamber 72 is provided at the top of the cylinder 71, a discharge port is provided at the bottom of the diamond storage chamber 72, a mesh 73 is provided on the discharge port, a rotatable discharge baffle 74 is provided at the bottom of the mesh 73, and the discharge port is opened or closed by rotating the discharge baffle 74. In addition, a material guide baffle 75 is provided at the bottom of the cylinder 71.

[0033] The scattering process of the diamond scattering mechanism 7 is as follows: a large number of diamonds are manually poured into the diamond storage chamber 72. When the mechanism does not start working, the material discharge baffle 74 is located on the side of the leakage net 73 to prevent the diamonds from leaking out when not working. When the mechanism starts working, the blade-type swing cylinder hits the material discharge baffle 74 to rotate. During the rotation, the diamonds will fall evenly through the leakage net 73. During the falling process, the guide baffle 75 blocks the diamonds for easy recovery. Correspondingly, a diamond particle collection box 8 is provided on the frame and directly below the scattering mechanism, and a leakage net 73 is provided at the top entrance of the diamond particle collection box 8.

[0034] The bottom of the inner side of the composite glue pool 13 is provided with a stirrer 131. The stirrer 131 is used to stir the solder and the glue to form a mixed solder, and the stirrer 131 is driven by a motor.

[0035] A mechanical claw 12 is provided on the side of the frame, and the mechanical claw 12 is used to transfer the core drill.

[0036] The conveyor belt 16 is located between the first clamp 11 and the second clamp 6 and is used to convey the coring drill.

[0037] A right chuck 17 and a left chuck 4 for transferring the coring drill are respectively disposed on both sides above the first clamp 11 . The right chuck 17 and the left chuck 4 can both move horizontally and move up and down.

[0038] A soft eccentric wheel pressing head 1 which can be raised, lowered and rotated is provided directly above the first clamp 11 .

[0039] Soft compacting grippers 14 are provided on both sides of the upper side of the first clamp 11 , and the two soft compacting grippers 14 can move horizontally and vertically.

[0040] The finished product box 5 is used to place the core drill after processing.

[0041] The electronic control system is used to control the operation of the entire device.

[0042] The utility model is also provided with a monitor for monitoring the distribution of diamond abrasive grains in the core drill, the monitor is arranged near the first clamp 11, the monitor transmits the monitoring data to the electric control system, and the electric control system controls the falling and compaction of the diamond abrasive grains. The monitor can be a sensor or a camera.

[0043] Among them, the first clamp 11 and the second clamp 6 both adopt the internal support chuck in the prior art. The internal support chuck is clamped pneumatically, and the internal support chuck device is generally divided into three parts, a spring chuck, a pull rod, and a tail pneumatic power rod. The spring chuck is connected to the pull rod through a thread, and the pull rod passes through the tail of the spindle and is connected to the pneumatic power rod. The conical surface of the spring chuck is directly in contact with the conical surface of the spindle. The pneumatic power rod provides power to the pull rod through the cylinder, and the pull rod drives the spring chuck to achieve clamping and loosening. The chuck is made according to the size of the workpiece hole, and different chucks can be replaced for different workpieces.

[0044] The screens on the diamond spreading mechanism 7 and the diamond particle collecting box 8 can be replaced. The diameter of the screen is determined by the diameter of the diamond and is generally 10% larger than the diameter of the diamond.

[0045] The horizontal movement of the left chuck 4 and the right chuck 17 are controlled by the barless cylinder 3, and the standard horizontal movement range is 900mm (can be customized according to needs), and the vertical movement (lifting) is controlled by the standard cylinder with a standard movement range of 300mm (can be customized according to needs).

[0046] The mechanical claw 12 is a multi-axis manipulator, and is driven by a standard cylinder and a blade-type swing cylinder. The horizontal motion range of the standard cylinder is 900 mm, and the vertical motion range of the standard cylinder is 600 mm. The blade-type swing cylinder has a motion range of 360°.

[0047] The running speed of the conveyor belt 16 is generally designed to be 1 m / s, and can also be customized according to demand.

[0048] The working principle of this utility model:

[0049] Loading process: After programming and parameter setting using the console panel or computer, the workpiece (coring drill) is grabbed from the workpiece storage box 9 by the mechanical claw 12, and then the mechanical claw 12 is rotated 180 degrees by the blade-type swing cylinder, and then moved by the standard cylinder to the top of the composite glue pool 13. Then the standard cylinder works to make the working surface of the workpiece extend into the composite glue pool, and the glue mixture is applied to the surface of the diamond core drill tooth base body, with a coating thickness of about 1mm-3mm. A mixed material of 1:2 of brazing material and PVAL glue is selected. After the working surface is glued, the workpiece is fixed on the first fixture 11 on the rotator 10 by the mechanical claw 12. The first fixture 11 is tilted 60 degrees and clamps the workpiece. Then the diamond spreading mechanism 7 is lowered to scatter diamonds, and the rotator 10 can drive the workpiece to rotate when scattering diamonds. Through the rotation of the rotator 10 and the diamond spreading mechanism 7, the diamonds can be evenly spread on the surface of the workpiece, so that the diamond concentration is between 50% and 75% (mass concentration), that is, in a two-dimensional model of 30mm×6mm, the number of diamonds reaches a range of 88-129, and 650μm-800μm cubic octahedral diamond abrasive grains are selected. The diamonds that are not spread on the workpiece fall into the diamond particle box 8 through the sieve to prevent waste and facilitate recycling.

[0050] Compacting process: The mechanical claw 12 removes the workpiece and places it on the conveyor belt 16, which is driven by the motor to transport the workpiece to the designated position. The barless cylinder 3 of the right chuck controller 15 sends the workpiece to the second fixture 6, and the second fixture 6 clamps the workpiece. The soft compacting gripper 14 is extended downward by the standard cylinder to the working position of the workpiece, and then the standard cylinder moves to move closer to achieve the compaction of the outer wall. After the outer wall is compacted, it is reset. Then, the soft compacting gripper 14 is brought together and moved by the standard cylinder to press down to achieve the compaction of the top. Then, the soft eccentric wheel pressure head 1 extends downward to the inside of the workpiece, and the motor drives the soft eccentric wheel pressure head 1 to rotate, and then rotates to achieve the purpose of compacting the inside. After compaction is completed, the soft eccentric wheel pressure head 1 is lifted, the second fixture 6 is released, and the barless cylinder 3 of the left chuck controller 2 controls the left chuck 4 to take out the workpiece. The left chuck 4 is controlled by a leverless cylinder to place the workpiece in the finished product box 5, so that the exposed height of the diamond is controlled within a range of 450 μm-750 μm, thereby completing the compaction process of the workpiece.

[0051] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
