Description

Technical Field

[0001] The invention belongs to the technical field of high-efficiency numerically controlled thread grinders, and in particular relates to an automatic tool setting device for a grinding wheel of a high-efficiency numerically controlled thread grinder. Background Art

[0002] In the precision grinding of traditional threads such as trapezoidal screws, ball screws and worms, the grinding wheel tool setting is usually completed by workers manually. Taking ball screw processing as an example, by turning the feed handwheel of the machine tool's lateral feed mechanism, the grinding wheel slowly enters the spiral groove roughly machined out of the threaded workpiece, and then the handwheel of the machine tool's longitudinal feed mechanism is turned to slowly move the grinding wheel along the workpiece axis until the grinding wheel contacts one side of the workpiece's spiral groove to generate sparks, and then the longitudinal feed mechanism handwheel is turned in the opposite direction until the grinding wheel contacts the other side of the workpiece's spiral groove to generate sparks; according to the scale value passed by the reverse rotation of the handwheel, it is rotated back 1 / 2 to make the center of the grinding wheel coincide with the center of the workpiece's spiral groove, thereby achieving thread tool setting. During the tool setting process, the operator mainly relies on listening to the grinding sound and watching the grinding sparks to confirm the status of the tool setting. This manual tool setting method is not only cumbersome, time-consuming, labor-intensive, inefficient, and not conducive to labor protection, but the tool setting accuracy is completely dependent on the operator's experience and operating level. Tool setting is performed by observing grinding sparks, and the consistency of the position accuracy and dimensional accuracy of the processed workpiece is poor, making it difficult to meet the interchangeability requirements.

[0003] The Chinese patent with the authorization announcement number CN101898316B discloses an automatic tool setting device for a CNC external thread grinder. The automatic tool setting device for an external thread grinder adopts a two-point contact type of precision probe, automatically measures and calculates the coordinate value of the tool setting position of the threaded workpiece, and automatically controls the tool setting movement. The tool setting process does not require human intervention, is relatively accurate and fast, improves the accuracy and efficiency of the tool setting of the external thread grinder, ensures the consistency of the position accuracy and dimensional accuracy of the processed workpiece, is conducive to safety protection, and solves the problem of manual tool setting being cumbersome, labor-intensive, and requiring high technical level of the operator; it can be used for large CNC external thread machines whose longitudinal movement is the movement of the drag plate; it is also suitable for small and medium-sized CNC external thread machines whose longitudinal movement is the movement of the worktable.

[0004] However, this technical solution still has at least the following defects: although the automatic tool setting device of this solution can set the tool efficiently and accurately, when the grinding wheel is seriously worn, the automatic tool setting device cannot issue an alarm to remind the operator to replace it, and in this case, continuing to use the grinding wheel will lead to a decrease in the quality of the processed workpiece.

In this setting, the tension of the spring 407 pulls the plug plate 406 to reset through the fixed plate 408, so that the plug plate 406 drives the first connecting plate 403 to move, and at the same time, when the spring 407 drives the plug plate 406 to move, the fixed plate 408 on it hits the limit frame 405 and makes a sound, so as to warn the operator to stop the machine in time.

[0051] like Figure 6 , Figure 7As shown, further, a fixing frame 410 is fixedly installed on one side of the limit frame 405, and an insert block 411 is slidably connected to one end of the fixing frame 410.

[0054] like Fig.11 , Fig.12 As shown, further, the rotating shaft 301 is movably connected to one end of the grinding wheel 312 with two symmetrically distributed blocks 304, and one side of each block 304 is rotatably connected to two first pull rods 305, and one end of the plurality of first pull rods 305 is rotatably connected to a second pull rod 306, and one end of the second pull rod 306 is fixedly installed with a third pull rod 307, and both ends of the third pull rod 307 movably penetrate the rotating shaft 301 and extend to the outside.

[0055] like Fig.12As shown, further, bearings 308 are fixedly installed at both ends of the third pull rod 307, and the bearings 308 are movably sleeved in the rotating shaft 301. Pull plates 309 are fixedly installed at both ends of the bearings 308, and the two pull plates 309 are respectively fixedly connected to one end of the two strip blocks 400. In this configuration, the strip block 400 drives the third pull rod 307 to move through the pull plates 309 and the bearings 308.

[0056] like Fig.11 , Fig.12 As shown, further, a mounting ring 310 is fixedly installed inside the grinding wheel 312, and the inner wall of the mounting ring 310 is provided with two symmetrically distributed slots 311, and the two slots 311 are respectively matched with the two blocks 304. In this configuration, the grinding wheel 312 is firmly installed through the matching relationship between the slots 311 and the blocks 304.

[0057] The implementation principle of the grinding wheel automatic tool setting device of the high-efficiency CNC thread grinder of this embodiment is as follows: when grinding, the driving motor 102 drives the first bevel gear 106 to rotate, the first bevel gear 106 drives the second bevel gear 107 to rotate by meshing, the second bevel gear 107 drives the transmission sleeve 104 to rotate, the transmission sleeve 104 drives the transmission shaft 202 to rotate through the clamping plate 105, the transmission shaft 202 drives the fourth bevel gear 303 to rotate, the fourth bevel gear 303 drives the third bevel gear 302 to rotate by meshing, so that the rotating shaft 301 rotates, the rotating shaft 301 drives the grinding wheel 312 to rotate through the clamping block 304 and the clamping groove 311, so as to perform grinding, and at the same time, the laser rangefinder 505 always monitors the distance between the edge of the grinding wheel 312;

[0058] When the grinding wheel 312 is worn, the distance between the edge of the grinding wheel 312 and the laser rangefinder 505 increases. At this time, the laser rangefinder 505 measures the increased value and feeds it back to the servo motor 204. The servo motor 204 rotates after receiving the signal, and drives the second gear 207 to rotate through the first gear 205. The second gear 207 drives the mounting plate 200 to move through the spiral groove 208 and the first gear 209. When the mounting plate 200 moves, it drives the transmission shaft 202, the support shell 300, and the rotating shaft 301 and other structures to move, so that the grinding wheel 312 moves, and the automatic tool setting of the grinding wheel 312 is realized.

[0059] When the mounting plate 200 moves, the third gear 501 is driven to move. The third gear 501 realizes self-rotation by meshing with the first rack 500, and drives the second rack 502 to move to one side by meshing with the second rack 502. At this time, the second rack 502 moves relative to the mounting plate 200, and because the mounting plate 200 moves itself, the movement speed of the second rack 502 is twice that of the mounting plate 200. When the second rack 502 moves, it drives the outer frame 503 to move. The outer frame 503 drives the movable frame 504 to move. The movable frame 504 drives the laser rangefinder 505 to move and reduce the distance between the laser rangefinder 505 and the edge of the grinding wheel 312. When the grinding wheel 312 is set, the distance between the laser rangefinder 505 and the edge of the grinding wheel 312 is in the initial setting state. At this time, the tool setting is completed.

[0060] When the outer frame 503 moves, the support plate 416 is driven to move. The support plate 416 drives the limit frame 405, the fixing frame 410 and the plug block 411 to move, and drives the plug plate 406 to move through the slot 409. At this time, the plug plate 406 drives the first connecting plate 403 to slide in the strip block 400. When the plug block 411 moves, it drives the third blocking rod 412 to move. When the third blocking rod 412 moves to the guide inclined surface 415, the third blocking rod 412 moves to one side under the action of the guide inclined surface 415, and drives the plug block 411 to disengage from the slot 409. At this time, the tension of the spring 407 pulls the plug plate 406 to reset through the fixing plate 408, so that the plug plate 406 06 drives the first connecting plate 403 to move, and drives the second blocking rod 402 to move to one side under the action of the first guide groove 404, the second blocking rod 402 drives the strip block 400 to move to one side, the strip block 400 drives the third pulling rod 307 to move through the pulling plate 309 and the bearing 308, the third pulling rod 307 pulls the first pulling rod 305 through the second pulling rod 306, so that the two clamping blocks 304 are retracted and disengaged from the clamping groove 311, at this time, the grinding wheel 312 is unlocked, and when the spring 407 drives the plug plate 406 to move, the fixed plate 408 thereon hits the limit frame 405 and makes a sound, so as to warn the operator to stop the machine in time, and then replace the grinding wheel 312;

[0061] When the replacement is completed, push the two first connecting plates 403, and control the servo motor 204 to reset and rotate, push the first connecting plates 403 to align the slot 409 with the plug 411, and the servo motor 204 rotates in the opposite direction to move the support plate 416 and other structures in the opposite direction, thereby driving the plug 411 to be inserted into the slot 409.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
