Description

Technical Field

[0001] The invention belongs to the field of fine-diameter hard and brittle material tubes, in particular to a device for processing fine and brittle material tubes. Background Art

[0002] Due to process limitations in the manufacturing process of piezoelectric ceramic tubes with equal diameter and wall thickness for droplet injection nozzles, the tube diameter is very small (1.35mm) and the outer surface roughness is unqualified, which causes certain differences in the consistency of the manufactured nozzle products.

[0003] For example, when making a micro-droplet jet nozzle, a piezoelectric ceramic tube with equal wall thickness is required. Since the diameter of each piezoelectric ceramic tube after firing is larger than the actual size required at the beginning of the design, it is necessary to process its outer diameter to ensure that each piezoelectric ceramic tube has the same wall thickness, outer wall diameter and smooth surface, so as to ensure the consistency of the nozzle. The piezoelectric ceramic tube has an outer diameter of 1.35mm, an inner diameter of 0.65mm, and a length of 20mm. It is made of PZT piezoelectric ceramic material, which is hard and brittle and belongs to a micro-fine brittle material tube (the inner diameter of the micro-fine brittle material tube is 0.5-1.2mm, and the outer diameter is 1.3-2mm).

[0062] Here’s how it works:

[0063] Step 1: After the second motor 2-3 and the first motor 3-9 are powered on, the corresponding motor speeds are adjusted, wherein the guide wheel speed is 10-300 rpm and the grinding wheel speed is 1000-2500 rpm;

[0064] Step 2: Manually rotate the hand wheel 4-5 clockwise to rotate the screw of the ball screw pair 4-9, and push the nut of the ball screw pair 4-9 to drive the sub-spindle box bracket adjustment plate 4-4 to slide on the guide rail 4-8. Drive the guide wheel 3-10 to move toward the grinding wheel 2-6. When the distance between the guide wheel 3-10 and the grinding wheel 2-6 is approximately equal to the outer diameter of the fine and brittle material tube to be processed, adjust the fine-tuning structure 5, manually rotate the limit rod 5-15 clockwise to drive the height adjustment plate 5-6 to rise, and the height adjustment plate 5-6 drives the shim mounting plate 5-3 and the material receiving plate 5-13 to rise. Manually rotate the longitudinal fine-tuning bolt 5-5 counterclockwise to drive the mounting plate 5-2 to move toward the guide wheel 3-10, and lock the locking screw 5-17 after the fine and brittle material tube is tangent to the guide wheel 3-10;

[0065] Step 3, manually turn the manual fine-tuning hand wheel 4-5 clockwise to make the fine and brittle material tube to be processed contact with the grinding wheel 2-6, lock the screw locking block 4-2, and keep the position of the guide wheel 3-10 unchanged;

[0066] Step 4, after debugging is completed, the fine and brittle material tube to be processed is placed in the feed protection groove 5-4 in sequence, the guide wheel 3-10 drives the fine and brittle material tube to be processed to move clockwise, and the grinding wheel 2-6 moves counterclockwise, and the fine and brittle material tube to be processed is ground by using the speed difference.

[0067] In the above technical solution, a fine adjustment structure 4 is set for adjusting the height and spacing position of the micro-brittle material tube to be processed relative to the guide wheel 3-10 and the grinding wheel 2-6. The longitudinal part of the fine adjustment structure adopts the screw principle. Adjusting and rotating the longitudinal fine adjustment bolt 5-5 can adjust the distance between the micro-brittle material tube to be processed and the grinding wheel 2-6. The vertical adjustment adopts the parallel lifting principle. The rotating limit rod 5-15 can drive the height adjustment plate limit plate 5-10 to make up and down fine adjustments under the action of the parallel connecting rod 5-7, so as to achieve the height adjustment between the micro-brittle material tube to be processed and the grinding wheel 2-6, which solves the technical problem of the difficulty in processing the micro-brittle material tube in the prior art.

[0068] The size of the guide wheel structure 3 and the grinding wheel structure 2 used is smaller than the wheel diameter of other grinding equipment, and the motor driving the guide wheel 3-10 and the grinding wheel 2-6 is also smaller in power and size than the motors of other equipment. The inner bearing of the main shaft uses high-precision bearings to reduce the vibration caused by centrifugal force when the grinding wheel rotates at high speed.

[0069] On the one hand, the water tank 1 provides cooling water when grinding the micro-fine and brittle material tube to be processed, and on the other hand, it provides a base platform for the entire equipment, and also plays a shock-absorbing role after water is filled. The grinding wheel structure 2 uses diamond grinding wheels with different high moduli, driven by a motor, to provide stable high-speed rotation for the grinding wheel, with a maximum speed of 3000r / min. The guide wheel structure 3 rotates the guide wheel in the horizontal direction by a small angle through the rotating shaft to control the rotation and feed speed of the micro-fine and brittle material tube to be processed. The feed structure 4 uses high-precision guide rails and ball screw pairs to make the guide wheel move longitudinally, which is mainly used for the installation of the guide wheel and the adjustment of the distance direction between the guide wheel and the grinding wheel. When adjusted to the appropriate position, the screw locking block can lock the screw to ensure the position of the guide wheel; the fine-tuning structure 5 is used to adjust the position of the micro-diameter hard and brittle material tube of the workpiece between the two grinding wheels.

[0072] A sub-spindle synchronous pulley pressure plate 3-8 is arranged at the lateral front end of the sub-spindle 3-17.

[0073] In the above technical solution, the secondary spindle synchronous pulley pressure plate 3-8 is provided to press the secondary spindle synchronous pulley 3-7 to prevent the secondary spindle synchronous pulley 3-7 from moving in the axial direction.

[0074] A motor support rib 2-11 is provided between the motor support base plate 2-13 and the vertical mounting plate 2-12.

[0075] In the above technical solution, setting the motor bracket rib 2-11 can make the structure of the bracket base plate 2-13 and the vertical mounting plate 2-12 more stable.

[0076] The spindles 2-14 on both sides of the spindle box 2-2 are respectively sleeved with a first spindle cover plate 2-5 and a second spindle cover plate 2-10.

[0077] In the above technical solution, the first spindle cover plate 2-5 and the second spindle cover plate 2-10 are used to limit the axial movement of the spindle box 2-2 on the spindle 2-14.

[0078] A screw support cover 4-6 is provided at the longitudinal rear end of the screw fixing support 4-7, the longitudinal rear end of the screw of the ball screw pair 4-9 passes through the screw support cover 4-6, and a No. 1 small round nut 4-1 is provided between the screw support cover 4-6 and the screw of the ball screw pair 4-9.

[0079] In the above technical solution, the screw support cover 4-6 is used to limit the axial movement of the screw fixing support 4-7, and the No. 1 small round nut 4-1 is used to connect the screw support cover 4-6 and the screw of the ball screw pair 4-9.

[0080] The first sub-spindle box cover plate 3-11 and the second sub-spindle box cover plate 3-13 are respectively arranged on the lateral ends of the sub-spindle 3-17 extending out of the sub-spindle box 3-3.

[0081] In the above technical solution, the first sub-spindle box cover plate 3-11 and the second sub-spindle box cover plate 3-13 are used to limit the axial movement of the sub-spindle box 3-3 on the sub-spindle 3-17.

[0082] Tension spring fixing members 5-11 are respectively arranged on the two transverse end surfaces of the pad iron mounting plate 5-3, and tension springs 5-16 are fixed on the tension spring fixing members 5-11.

[0083] In the above technical solution, the tension spring fixing member 5-11 is used to fix one end of the tension spring 5-16 to facilitate the compression and stretching of the tension spring 5-16.

[0084] An oblong hole is provided on the limiting plate 5-8, and a limiting rod 5-15 is arranged in the oblong hole.

[0085] In the above technical solution, the oblong hole facilitates the upward and downward movement of the limiting rod 5-15.

[0086] A guide column 3-16 is arranged on the sub-spindle box bracket adjustment plate 4-4, and the guide column 3-16 extends out of the bottom of the sub-spindle box bracket 3-2.

[0087] In the above technical solution, the guide column 3-16 limits the position of the sub-spindle box bracket 3-2, so that when the fine-tuning screw on the guide wheel group angle adjustment block 4-3 is fine-tuned, the sub-spindle box bracket 3-2 rotates around the guide column 3-16.
