Description
Technical Field
[0001] The invention relates to the technical field of grinding processing, in particular to a diamond grinding wheel slotting processing machine tool. Background Art
[0002] The diamond grinding wheel is composed of a diamond abrasive layer, a transition layer and a matrix. In the process of cutting brittle materials, the diamond grinding wheel is used as a cutting tool. The diamond grinding wheel forms an incision on the surface of the object by grinding. During the processing of the diamond grinding wheel, the diamond grains on the surface will become passivated. When the diamond grinding wheel blade becomes blunt during the cutting of high-hardness materials, the cutting edge will crack. However, how to detect the dullness of the high-speed rotating diamond grinding wheel is a problem.
[0003] Since the diamond grinding wheel is always rotating at high speed during the processing, the wear condition cannot be accurately obtained by image processing. Therefore, when passivation occurs, the product has already cracked. Summary of the invention
[0004] The object of the present invention is to provide a diamond grinding wheel slotting machine tool to solve the problems raised in the above background technology.
[0005] To achieve the above object, the present invention provides the following technical solutions:
[0006] A diamond grinding wheel slotting machine tool comprises a feeding frame and a processing frame, wherein the feeding frame is slidably connected with two clamping pushers for clamping workpieces, the clamping pushers slide with the feeding frame through a lateral motion mechanism, the processing frame is slidably connected with a grinding processing platform, the bottom of the grinding processing platform is rotatably connected with a diamond grinding wheel, the diamond grinding wheel rotates counterclockwise, and a detection component is installed on the grinding processing platform;
[0007] The detection assembly comprises a detection motion unit rotating on the grinding platform, an L-shaped bracket is fixedly connected to the surface of the detection motion unit at equal intervals, a measuring plate is rotatably connected to the L-shaped bracket, an angle sensor is arranged between the measuring plate and the L-shaped bracket, the angle sensor respectively obtains two angle information of the detection tilt angle and the vertical angle after wear, and the time monitoring unit obtains the time Δt used from the detection tilt angle to the vertical angle;
[0008] A longitudinal pushing mechanism is installed on the clamping pusher, and a clamping mechanism for clamping a workpiece is fixedly connected to the longitudinal pushing mechanism. A cutting pushing speed adjustment unit is arranged between the longitudinal pushing mechanism and the driving source, and the speed adjusted by the cutting pushing speed adjustment unit is inversely proportional to Δt.
[0009] As a further solution of the present invention: the top of the L-shaped bracket is located above the diamond grinding wheel, a counterweight block is arranged at the bottom of the measuring plate, a torsion spring is arranged between the measuring plate and the L-shaped bracket, and the measuring plate always remains perpendicular to the horizontal plane in a stationary state.
[0010] As a further solution of the present invention: the detection motion unit is controlled to rotate by a fixed-distance conveying controller, and the fixed-distance conveying controller monitors the measuring plate from an inclined angle to a vertical angle after wear and controls the detection motion unit to move a single step.
[0011] As a further solution of the present invention: the Δt monitored by the time monitoring unit has three range intervals, and the three range intervals respectively correspond to the three action states of uniform speed movement, variable speed movement and stop movement of the longitudinal pushing mechanism.
[0012] As a further solution of the present invention: the distance between two adjacent L-shaped brackets is smaller than the length of the measuring plate.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] The top of the diamond grinding wheel is in contact with the circumference of the diamond grinding wheel by using an inclined measuring plate. The measuring plate uses gravity to act on the diamond grinding wheel. When the relative force is small, the grinding speed of the diamond grinding wheel on the measuring plate is greatly reduced, but the diamond grinding wheel still has a grinding effect on the measuring plate. The wear of the measuring plate can just reflect whether the diamond grinding wheel is blunt. Therefore, the cutting feed speed can be reduced in time or the cutting can be stopped to replace the grinding wheel. This can prevent the blunt diamond grinding wheel from causing product cracking.

[0022] See also Figure 1-Figure 5 In this embodiment, a feeding rack 1 and a processing rack 3 are included. The feeding rack 1 is slidably connected with two clamping pushers 2 for clamping workpieces. The clamping pushers 2 slide with the feeding rack 1 through a lateral motion mechanism 21. The processing rack 3 is slidably connected with a grinding processing platform 4. The bottom of the grinding processing platform 4 is rotatably connected with a diamond grinding wheel 41. The diamond grinding wheel 41 rotates counterclockwise. A detection component 5 is installed on the grinding processing platform 4.
[0023] In this embodiment, the feed rack 1 and the processing rack 3 are vertically distributed, the processing rack 3 is located at the top, and the feed rack 1 is located at the bottom. The feed rack 1 plays a role of sliding guide and sliding support for the clamping pusher 2. The clamping pushers 2 cooperate with each other to clamp the workpiece, and the grinding processing platform 4 can also be displaced on the top, thereby increasing flexibility and improving the applicable scope of processing workpieces. The lateral motion mechanism 21 controls the clamping pusher 2 to slide with the feed rack 1, so that the distance between the two clamping pushers 2 can be adjusted. The adjusted clamping pusher 2 can clamp more diverse workpiece products.
[0024] In this embodiment, the detection component 5 includes a detection motion unit 51 rotating on the grinding processing platform 4, and an L-shaped bracket 53 is equidistantly fixedly connected to the surface of the detection motion unit 51, and a measuring plate 52 is rotatably connected to the L-shaped bracket 53. An angle sensor 521 is arranged between the measuring plate 52 and the L-shaped bracket 53. The angle sensor 521 respectively obtains two angle information of the detection tilt angle and the vertical angle after wear, and the time monitoring unit 522 obtains the time Δt taken for the detection tilt angle to change to the vertical angle. The top of the L-shaped bracket 53 is located above the diamond grinding wheel 41, and a counterweight block is arranged at the bottom of the measuring plate 52. A torsion spring is arranged between the measuring plate 52 and the L-shaped bracket 53, and the measuring plate 52 always remains perpendicular to the horizontal plane in a stationary state.
[0025] In this embodiment, the diamond grinding wheel 41 is driven by a driver to rotate at high speed on the grinding processing platform 4, and the detection component 5 detects the wear of the cutting surface of the diamond grinding wheel 41. Figure 4 , the detection motion unit 51 drives the L-shaped bracket 53 to move toward the diamond grinding wheel 41, and the measuring plate 52 will come into contact with the diamond grinding wheel 41, causing the measuring plate 52 to tilt. The measuring plate 52 uses its own weight or a small amount of elastic force to drive the measuring plate 52 to maintain contact with the diamond grinding wheel 41. Compared with the pushing force of cutting, the contact force of the measuring plate 52 on the diamond grinding wheel 41 is smaller than the pushing force of the diamond grinding wheel 41 on the cutting workpiece. Therefore, the period of the groove body produced by the grinding of the diamond grinding wheel 41 on the measuring plate 52 is long. The hardness of the measuring plate 52 is less than the hardness of the cutting workpiece. When the surface of the diamond grinding wheel 41 becomes blunt, since the hardness of the measuring plate 52 is less than the hardness of the cutting workpiece, the surface reaction of the measuring plate 52 will be more obvious. When the diamond grinding wheel 41 is sharp, when the same measuring plate 52 acts on the diamond grinding wheel 41, the time for the measuring plate 52 to rotate to vertical is short, and when the diamond grinding wheel 41 becomes blunt, the measuring plate 52 acts on the diamond grinding wheel 41, and the time for the measuring plate 52 to rotate to vertical increases. Whenever the inclined measuring plate 52 becomes vertical, the time monitoring unit 522 obtains the time Δt used from the detection of the tilt angle to the vertical angle, and controls the detection motion unit 51 to move a fixed step through the fixed-distance conveying controller 511. The fixed step ensures that the rear measuring plate 52 contacts the diamond grinding wheel 41 and maintains the tilted state, mainly for continuous grinding monitoring. The two angles of the measuring plate 52 are the tilt angle and the vertical angle. At the tilt angle, the measuring plate 52 contacts the diamond grinding wheel 41, and the measuring plate 52 uses gravity and the elastic force applied by the torsion spring to the measuring plate 52, so that a relative force is generated between the measuring plate 52 and the diamond grinding wheel 41, and the diamond grinding wheel 41 can act on the measuring plate 52. When the measuring plate 52 remains vertical, it means that the measuring plate 52 completely cuts out the groove body, and the time is calculated based on these two angles as references to deduce the wear state. Figure 4 In this state, the measuring plate 52 is not directly above the diamond grinding wheel 41. When the vertical measuring plate 52 moves backward, a tilting state may occur, and the time of the measuring plate 52 is not recorded in this state.
[0026] In this embodiment, a longitudinal pushing mechanism 22 is installed on the clamping pusher 2, and a clamping mechanism 23 for clamping the workpiece is fixedly connected to the longitudinal pushing mechanism 22. A cutting pushing speed adjustment unit 531 is arranged between the longitudinal pushing mechanism 22 and the driving source, and the speed adjusted by the cutting pushing speed adjustment unit 531 is inversely proportional to Δt.
[0027] In this embodiment, the above describes the relationship between the measuring plate 52 and the diamond grinding wheel 41, and the shorter the Δt time is, the sharper the diamond grinding wheel 41 is, and the longer the Δt time is, the duller the diamond grinding wheel 41 is. At the beginning of the processing, the longitudinal pushing mechanism 22 pushes the clamping mechanism 23 to make the workpiece and the diamond grinding wheel 41 move relative to each other. When the diamond grinding wheel 41 becomes dull, if the feed speed of the longitudinal pushing mechanism 22 remains unchanged, it is easy to cause cracking problems at the cutting mouth. Therefore, the speed adjusted by the cutting push speed adjustment unit 531 is inversely proportional to Δt, so the feed speed can be appropriately reduced to reduce the risk of cracking. The cutting push speed adjustment unit 531 can be composed of a controller and a transmission, and the controller monitors and controls the transmission to adjust the conveying speed of the longitudinal pushing mechanism 22.
[0028] In this embodiment, the detection motion unit 51 is controlled to rotate by the fixed-distance conveying controller 511. The fixed-distance conveying controller 511 monitors the measuring plate 52 from the tilt angle to the vertical angle after wear, and then controls the detection motion unit 51 to move one step at a time. This method mainly realizes the long-term detection of the diamond grinding wheel 41. When the length of the cut groove is large, the fixed-distance conveying controller 511 controls the detection motion unit 51 to move, so that multiple measuring plates 52 contact the diamond grinding wheel 41 in turn, thereby forming multiple detection intervals for continuous detection.
[0029] In this embodiment, the Δt monitored by the time monitoring unit 522 has three range intervals, and the three range intervals correspond to the three action states of uniform motion, variable speed motion and stop motion of the longitudinal pushing mechanism 22 respectively; the first interval is a normal interval, and the speed of the longitudinal pushing mechanism 22 remains unchanged. In the second interval, when the Δt time increment reaches the set standard, the pushing speed of the longitudinal pushing mechanism 22 is reduced. When the Δt time increment exceeds the set standard, the longitudinal pushing mechanism 22 is in a stopped state, and the diamond grinding wheel 41 needs to be replaced.
[0030] In this embodiment, in actual application, a new diamond grinding wheel 41, a severely worn diamond grinding wheel 41 and a moderately worn diamond grinding wheel 41 are selected to detect the same type of measuring plate 52, so as to obtain multiple Δt, and the monitoring range of Δt can be set according to Δt.
[0031] In this embodiment, the distance between two adjacent L-shaped brackets 53 is smaller than the length of the measuring plate 52. In order to prevent the inclined measuring plate 52 from contacting the rear measuring plate 52, causing the rear measuring plate 52 to shake.
[0032] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
