Description

Technical Field

[0001] This utility model relates to the field of diamond tool head processing technology, and in particular to a diamond tool head sharpening and grinding machine with a flexible processing structure. Background Technology

[0002] Diamond cutting tools require sharpening during the forming process. This sharpening operation involves using a grinding wheel to grind away a portion of the matrix, exposing the diamond particles. Existing sharpening machines for diamond cutting tools typically include a frame, a grinding device, and a placement device. The frame has a placement platform, and the placement device has a frame for arranging several cutting tools in a matrix. The frame is positioned on the placement platform in a way that allows it to move back and forth. The grinding device is mounted on the frame above the placement frame and is capable of moving up and down and left and right. The grinding device includes a grinding wheel and a motor drive to rotate the grinding wheel. In application, several cutting tools are neatly arranged in the placement frame. The grinding wheel moves up and down and left and right until its surface contacts the top surface of the cutting tools in the placement frame. Then, the placement frame moves back and forth, allowing the grinding wheel to sharpen the row of cutting tools. However, in this type of sharpening machine, the grinding wheel is fixed at a fixed height after being adjusted during operation. Since the cutting head cannot be processed with perfect precision, there will be slight deviations in the size of the cutting head, that is, there will be some fluctuation in the thickness and width of the cutting head. In this way, when the grinding wheel with a fixed height is installed during the sharpening operation, it will collide hard with the cutting head when processing a thicker cutting head, causing wear to the grinding wheel.

[0003] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

[0004] The purpose of this invention is to provide a diamond tool grinding machine with a flexible machining structure, in which the grinding wheel can adaptively adjust its installation height according to the thickness of the tool tip without causing a hard collision with the tool tip.

[0010] The aforementioned grinding wheel holder is a horizontal seat extending in the left-right direction. A first adjusting rod and a second adjusting rod, vertically arranged and spaced apart, are mounted on the top surface of the horizontal seat. A mounting plate is mounted on the front side of the aforementioned lifting seat, positioned above the horizontal seat. The mounting plate has corresponding vertically penetrating and front-back extending strip-shaped through holes corresponding to the first and second adjusting rods. The upper end of the first adjusting rod passes through one of these strip-shaped through holes, and a locking nut, limited to the outside of the strip-shaped through hole, is screwed onto the upper end of the first adjusting rod. The upper end of the second adjusting rod passes through another strip-shaped through hole, and a limiting nut is screwed onto the upper end of the second adjusting rod. Springs are fitted around the second adjusting rod between the limiting nut and the mounting plate, and between the mounting plate and the horizontal seat.

[0019] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0020] This utility model discloses a diamond tool tip sharpening and grinding machine with a flexible machining structure, such as... Figure 1-4 As shown, the device includes a frame 1, a grinding device, and a placement device. The placement device has a placement frame 21 and a movable seat 22. The movable seat 22 is mounted on the frame 1 in a manner that allows for lateral translation. The placement frame 21 rests flat on the movable seat 22. Specifically, the frame 1 has a lower base 11 and an upper frame 12. Both the upper frame 12 and the lower base 11 are square structures. The upper frame 12 is a hollow frame with an open bottom, located inside the lower base 11. The top surfaces of the upper frame 12 and the lower base 11 form a hollow square space. The central area of ​​the top surface of the lower base 11 has a boss 111. The movable seat 22 is a square seat. The movable seat 22 is placed flat on the top surface of the boss 111. The central area of ​​the boss 111 has a recessed channel that runs through it from front to back. A first lead screw (not shown in the figure) is rotatably installed in the channel and lies horizontally in the front-back direction. A first threaded block (not shown in the figure) is screwed onto the bottom surface of the movable seat 22 and is screwed onto the lead screw. A first drive motor (not shown in the figure) is fixedly installed on the front or rear side of the boss 111 and is fixedly connected to the first lead screw. In use, the first drive motor is started, the first lead screw rotates, and the rotation of the first lead screw drives the first threaded block to move along the first lead screw. The movable seat 22 moves back and forth together with the first threaded block.

[0021] The placement frame 21 is placed on the top surface of the movable seat 22. The placement frame 21 is a hollow square structure formed by four rods. Two of the four rods are movable in a way that allows them to translate towards the center of the placement frame 21. In this embodiment, the rods on the front and right sides are movable. The rod on the front side is called the front rod, and the rod on the right side is called the right rod. The front rod and the right rod are respectively pushed and translated by the cylinder 100. The cylinder that cooperates with the front rod is located on the front side of the front rod, and the cylinder that cooperates with the right rod is located on the right side of the right rod. The translation of the front rod and the right rod can make the arrangement of each cutter head close together, avoiding the translation of each cutter head 200 during processing.

[0022] The grinding device includes a mounting frame 31, a grinding wheel 32, and a rotation drive device for driving the grinding wheel to rotate. The mounting frame 31 is mounted on the frame 1 in a manner that allows it to move up and down and laterally. The grinding wheel 32 is rotatably mounted on the mounting frame 31 and is positioned above the placement frame 21. The rotation drive device is mounted on the mounting frame 31. The lateral translation direction of the placement frame 21 is perpendicular to the lateral translation direction of the mounting frame 31. Specifically, the mounting frame 31 has a translation seat 311, a lifting seat 312, and a grinding wheel seat 313. The translation seat 311 is mounted on the frame in a manner that allows it to move left and right and is positioned above the placement frame 21. That is, a gantry frame 112 is mounted on the frame. The translation seat 311 is a horizontal frame extending in the left and right direction. The body is located in front of the gantry frame 112, and a translation drive device for driving the translation seat to move laterally is installed on the gantry frame 112. Specifically, the gantry frame 112 is fixed on the top surface of the lower base 11. The gantry frame 112 consists of left and right opposing columns and a crossbeam at the upper end of the two columns. The placement frame 21 is located between the two columns. The crossbeam is located behind the translation seat 311. A screw block 311a is fixed on the rear side of the translation seat 311. A lead screw 301 lying horizontally in the left and right direction is fixedly installed on the crossbeam. A second drive motor 302 is located on the left or right end of the crossbeam. The output shaft of the second drive motor 302 is fixedly connected to one end of the lead screw 301. The second drive motor, the lead screw, and the screw block constitute the translation drive device. When started, the second drive motor 302 drives the lead screw 301 to rotate. The rotation of the lead screw 301 causes the screw block 311a to move along the lead screw 301, thereby causing the translation seat 311 to move left and right along the crossbeam of the gantry frame 112.

[0023] The lifting seat 312 is mounted on the translation seat 311 in a way that allows it to move up and down. That is, the lifting seat 312 is located in front of the translation seat 311. The translation seat 311 is equipped with a lifting drive device that drives the lifting seat 312 to move up and down. Specifically, the front side of the translation seat 311 has a front stand 311b that is vertically erected in the vertical direction. A vertically erected third lead screw (not shown in the figure) is rotatably mounted on the front side of the front stand 311b. That is, both the upper and lower ends of the front side of the front stand have protruding bosses. The two ends of the third lead screw are rotatably mounted on the two bosses through bearings. The lifting seat 312 is located in front of the front stand. A third screw block (not shown in the figure) is fixed to the rear side of the lifting seat 312 and screwed onto the outside of the third lead screw. A third drive motor 303 is mounted on the top surface of the front stand 311b. The output shaft of the third drive motor 303 faces downward and is fixedly connected to the upper end of the third lead screw. The third drive motor 303, the third lead screw, and the third screw block constitute the lifting drive device. In application, the third drive motor 303 drives the third lead screw to rotate. The rotation of the third lead screw causes the third screw block and the lifting seat 312 to move up and down along the front column. In this invention, to stabilize the translation of the lifting seat 312, slide rails extending in the vertical direction are fixed on the left and right sides of the front column located on the third lead screw. A slider that slides with the slide rails is fixed on the rear side of the lifting seat 312. The cooperation between the slide rails and the slider guides the lifting of the lifting seat 312.

[0024] The grinding wheel holder 313 is rotatably mounted on the lifting seat 312 and is located outside the front or rear side of the lifting seat 312. The lifting seat 312 is provided with a rotation-limiting structure that restricts the circumferential rotation of the grinding wheel holder 313 and allows the grinding wheel holder to swing up and down. In this embodiment, the grinding wheel holder 313 is located on the front side of the lifting seat 312 as an example. The grinding wheel holder 313 is located on the lower front side of the lifting seat 312. A fixed shaft 4 is fixedly mounted on the lifting seat 312 and is arranged horizontally in the left and right direction. That is, the fixed shaft 4 is locked on the lower rear side of the lifting seat 312. The left and right ends of the fixed shaft 4 are located outside the left and right sides of the lifting seat 312, respectively. That is, the length of the fixed shaft 4 is long. The grinding wheel seat 313 is rotatably mounted on the fixed shaft 4 in the left-right direction of the lifting seat 312. Specifically, mounting blocks 41 are respectively fitted onto the left and right ends of the fixed shaft 4, located on the left and right sides of the lifting seat 312. The mounting blocks 41 are rotatably mounted on the fixed shaft 4 via bearings 42. A vertically mounted upright plate 43 is locked to the front of the mounting blocks 41, and the grinding wheel seat 313 is fixedly engaged with the upright plate 43. Preferably, the grinding wheel seat 313 is a horizontal seat extending in the left-right direction. A horizontally extending rotating shaft 313a is rotatably mounted inside the grinding wheel seat 313 via bearings, with the left and right ends of the rotating shaft 313a extending out of the grinding wheel seat 313. On the left and right sides, the grinding wheel 32 is fixed to the right end of the rotating shaft 313a, and the rotation drive device is located at the left end of the rotating shaft 313a. The grinding wheel seat 313 is located in front of the two upright plates 43 and is locked together with the upright plates 43. The top surface of the grinding wheel seat 313 is equipped with a first adjusting rod 51 and a second adjusting rod 52 that are vertically arranged and spaced apart on the left and right. The front side of the lifting seat 312 is equipped with a mounting plate 312a above the grinding wheel seat 313. The mounting plate 312a has corresponding vertical through holes (not shown in the figure) that extend in the front and back directions and pass through the first adjusting rod 51 and the second adjusting rod 52. The first adjusting rod 51 is located on the right side of the first adjusting rod 52. The upper end of an adjusting rod 51 passes through a strip-shaped through hole on the right side, and a locking nut 511, which is limited to the outside of the strip-shaped through hole, is screwed onto the upper end of the first adjusting rod 51. The upper end of a second adjusting rod 52, located on the left side, passes through a strip-shaped through hole on the left side, and a limiting nut 521 is screwed onto the upper end of the second adjusting rod 52. Springs 522 are sleeved on the second adjusting rod 52 between the limiting nut 521 and the mounting plate 312a and between the mounting plate 312a and the cross seat. The mounting plate 312a, the first adjusting rod 51, the second adjusting rod 52, the locking nut 511, the limiting nut 521, and the springs 522 constitute the aforementioned rotation-limiting structure.In application, the bearing 42 enables the grinding wheel holder 313 to rotate around the fixed shaft 4. However, since the first adjusting rod 51 and the second adjusting rod 52 on the mounting plate 312a of the lifting seat 312 are both connected to the grinding wheel holder 313, the grinding wheel holder 313 can only swing back and forth with a small amplitude. That is, during processing, when the grinding wheel holder 313 moves forward, if the grinding wheel 32 encounters a thick cutting head, the high-speed rotation of the grinding wheel 32 caused by the rotation of the grinding wheel holder will cause the grinding wheel holder 313 to swing upward and forward at an angle, without causing a hard collision with the higher cutting head, thus achieving a flexible fit. At the same time, when the grinding wheel holder 313 swings upward and forward at an angle, the spring 522 is compressed upward. When the grinding wheel 32 re-contacts the precise cutting head 200, the spring 522 returns to its original position downward, causing the grinding wheel holder 313 to swing downward again and fall back to its initial position. In addition, the swing of the grinding wheel holder 313 can be finely adjusted by the cooperation of the first adjusting rod 51 and the locking nut 511.

[0025] The aforementioned rotation drive device includes a rotation drive motor 61, a driven pulley 62, a driving pulley 63, a lower transmission belt 64, a lower transmission pulley 65, an upper transmission pulley 66, and an upper transmission belt. The rotation drive motor 61 is fixed to the upper front side of the lifting seat 312 and is horizontally arranged along the left and right sides. The output end of the rotation drive motor 61 faces left. The driven pulley 62 is sleeved on the left end of the fixed rotating shaft 313a. The driving pulley 63 is rotatably sleeved on the left end of the fixed shaft 4 via a bearing. The driven pulley 62 and the driving pulley 63 are connected by the lower transmission belt 64. The left end of the fixed shaft 4 is rotatably sleeved with a bearing that is arranged side by side with the driving pulley 63 and is engaged with it in a concave-convex manner. The lower drive pulley 65 is connected to the upper drive pulley 66 located above the lower drive pulley 65 on the output shaft of the drive motor 61. The upper drive pulley and the lower drive pulley are connected by an upper drive belt (not shown in the figure). In application, the drive motor 61 is started, and the drive motor 61 drives the lower drive pulley 65 to rotate through the engagement of the upper drive pulley 66 and the upper drive belt. The lower drive pulley 65 is engaged with the drive pulley 63, and the drive pulley 63 rotates around the fixed shaft 4 accordingly. The rotation of the drive pulley 63 drives the driven pulley 62 to rotate through the lower drive belt 64. The rotation of the driven pulley 62 causes the rotating shaft 313a to rotate, thereby causing the grinding wheel 32 to rotate.

[0026] This utility model discloses a diamond tool head sharpening and grinding machine with a flexible processing structure. In application, several tool heads 200 are placed in a placement frame 21. The tool heads are arranged close together by translating the front and right rods of the placement frame 21. The lifting seat 312 descends, and the worktable of the grinding wheel 32 contacts the top surface of the tool heads 200. Then, the placement frame 21 moves backward, and the translation seat 311 moves left and right, allowing the grinding wheel 32 to sharpen the tool heads within the placement frame 21. During operation, if the sanding disc encounters a cutting head with inaccurate dimensions or a high overall height, the high-speed rotation of the grinding wheel 32 and the slight rotation of the grinding wheel holder 313 will cause the entire grinding wheel holder 313 to swing upwards. As the grinding wheel holder 313 swings upwards, the spring 522 is compressed. When the grinding wheel 32 contacts the standard cutting head in the placement frame again, the downward reset of the spring 522 causes the grinding wheel holder 313 to swing downwards accordingly, ensuring that the grinding wheel 32 can still contact the standard cutting head in the placement frame. Compared with existing technologies, this design allows the grinding wheel 32 to swing up and down at a certain angle according to the height of the cutting head during high-speed operation, achieving flexible cutting head alignment. This prevents hard impact wear when the sanding disc encounters a high cutting head, extending the service life of the sanding disc.

[0027] In this invention, a dust collection air box 7 is installed on the frame, located behind the placement platform and with its opening facing forward. The rear end of the dust collection air box 7 has an air intake extending rearward beyond the frame. Preferably, the dust collection air box 7 has a horn shape that gradually narrows from front to back. The dust collection air box 7 is closely attached to the rear side of the upper frame 12 and locked onto the upper frame 12. The dust collection air box 7 is located behind the gantry frame 112. A connection is provided between the gantry frame 112 and the rear inner sidewall of the upper frame 12. The connecting frame 8, which is locked together with the gantry frame, is a three-sided open square frame consisting of a bottom plate, a left side plate, and a right side plate. The rear side wall of the upper frame 12 has an opening that connects to the largest end of the chip collection box 7. The left side plate and the right side plate are located on the left and right sides of the opening, respectively. The bottom plate is located behind the boss 111. In use, the dust collection device can be connected to the air intake of the chip collection box 7 to remove the waste chips produced by the sanding disc, thus maintaining the cleanliness of the cutting head.
