Description

[0001] The present application relates to the field of tool setting, and in particular to a tool setting measuring device. Background Art

[0002] In the traditional CNC machining process, many tool setting scenarios are required, such as tool changing between rough machining and fine machining. During the CNC machining process, the tool may be worn or broken, and the tool needs to be replaced or adjusted, and then the tool setting operation is performed. When the CNC device cuts the flexible circuit board, due to the low thickness of the flexible circuit board, the precision requirement is high. The existing method is to fix an electrically charged clip at the tool of the CNC device and a clip on the flexible circuit board. When the clip at the tool touches the flexible circuit board, the circuit is turned on and an electrical signal is generated.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0034] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] The implementation of the present application is described in detail below in conjunction with specific embodiments.

[0037] like Figure 1-Figure 3 As shown, an embodiment of the present application proposes a tool setting measuring device, comprising a linear module 1, a probe module 2 installed at the output end of the linear module 1, a platform to be measured 3, and a tool setting module 4 installed on the platform to be measured 3 and electrically connected to the probe module 2; the tool setting module 4 comprises a tool setting housing 41, a trigger circuit board 42 arranged in the tool setting housing 41, a sliding component 43 slidably installed on the tool setting housing 41 and used to trigger the trigger circuit board 42, and a tool setting elastic member 44 arranged between the sliding component 43 and the tool setting housing 41; the probe module 2 comprises a probe housing 21, and a probe pin 22 installed on the probe housing 21; the linear module 1 can drive the probe module 2 to move to the top of the sliding component 43, and make the probe pin 22 press the sliding component 43.

[0038] In the embodiment of the present application, the Z-axis tool setting principle is as follows: the output end of the linear module 1 (that is, the head of the CNC device) is first installed with a tool, and the linear module 1 drives the tool to move to the top of the tool setting module 4, and the linear module 1 drives the tool down to press the sliding component 43, changing the electrical connection state between the sliding component 43 and the trigger circuit board 42, so as to trigger the tool setting module 4. At this time, the position of the Z axis is recorded as the reference value Z0 of the Z axis. After the tool is changed or the tool is worn, the above steps are repeated to record the Z axis position Z1 after the tool change. The difference between Z0 and Z1 is the difference of the tool in the Z axis direction after the tool change or the difference of tool wear, and then the main program compensates for it.

[0039] The principle of automatic tool setting in the Z direction when the CNC device is engraving and processing the flexible circuit board is as follows: the probe module 2 is installed on the output end of the linear module 1 (that is, the head of the CNC device) through the chuck, and the probe module 2 and the tool setting module 4 are electrically connected. The linear module 1 drives the probe needle 22 on the probe module 2 to contact the flexible circuit board waiting for processing on the test platform 3, and records the position of the Z axis, and records the X and Y values ​​at this time, and repeatedly measures the X, Y, and Z values ​​of other positions of the flexible circuit board. The surface is fitted according to the recorded data to complete the tool setting and leveling. After completion, the probe module 2 is moved to the top of the tool setting module 4, and the linear module 1 drives the probe needle 22 to press the sliding component 43, changing the electrical connection state between the sliding component 43 and the trigger circuit board 42, so as to trigger the tool setting module 4. At this time, the value of the Z axis is recorded as Z3. Then remove the probe, replace the tool, and the linear module 1 drives the tool to press the sliding component 43, changing the electrical connection state between the sliding component 43 and the trigger circuit board 42, so as to trigger the tool setting module 4. At this time, the Z axis value is recorded as Z4, and the leveling data (the value supplemented by the above main program) is subtracted from the difference between Z3 and Z4, and replaced with the Z value corresponding to the X and Y coordinates for processing. That is, during the tool setting process, the tool only needs to contact the tool setting module 4 once, and does not need to contact the workpiece such as the flexible circuit board on the platform 3 to be tested, so the tool is not prone to breakage.

[0040] The processing of curved surface measurement is similar to the above principle. It only needs the probe module 2 to measure the X, Y, and Z values ​​of the curved surface, and the curved surface is fitted through the X, Y, and Z coordinate data.

[0041] See also Figure 3-Figure 4 As another specific embodiment of the tool setting and measuring device provided by the present application, the tool setting housing 41 includes a hollow inner shell 411 and end covers 412 disposed at opposite ends of the hollow inner shell 411; a main control circuit board 45 electrically connected to the trigger circuit board 42 is disposed in the hollow inner shell 411. The hollow inner shell 411 can be an aluminum extrusion, and has sufficient space inside to install the main control circuit board 45; however, in the prior art, the space milled out of the entire workpiece is not large enough to install the main control circuit board 45.

[0042] See also Figure 3-Figure 5 As another specific embodiment of the tool setting and measuring device provided by the present application, a slide groove 4111 is provided on the inner wall of the hollow shell 411, and the main control circuit board 45 is inserted into the slide groove 4111; a positioning sink 4112 is provided at the end of the slide groove 4111, and a positioning boss embedded in the positioning sink 4112 is provided on the main control circuit board 45. After the main control circuit board 45 is installed in the slide groove 4111, it is not easy to slide along the slide groove 4111, and can be stably installed inside the hollow shell 411.

In the non-tool setting state, the main body of the tool setting module 4 (the tool setting housing 41 part) can be removed to reduce dust pollution generated by processing.

[0045] See also Figure 3 and Figure 5 As another specific embodiment of the tool setting measuring device provided by the present application, a tool setting installation hole 4115 is opened on the hollow inner shell 411, and a sliding sleeve 47 is installed in the tool setting installation hole 4115; the sliding assembly 43 includes a long tool setting pin 431 slidably installed on the sliding sleeve 47 and passing through the sliding sleeve 47, a tool setting seat 432 connected to the long tool setting pin 431, a tool setting block 433 installed on the tool setting seat 432, and a conductive seat 434 installed on the end of the long tool setting pin 431 away from the tool setting seat 432 and used to trigger the trigger circuit board 42; the trigger circuit board 42 is installed on the sliding sleeve 47; the tool setting elastic member 44 is a spring; the tool setting elastic member 44 abuts between the sliding sleeve 47 and the tool setting seat 432. The process of the sliding component 43 triggering the trigger circuit board 42 on the sliding sleeve 47 is as follows: in the initial state, the conductive seat 434 on the sliding component 43 contacts the trigger circuit board 42 to achieve electrical connection; when the sliding component 43 is subjected to the pressure of the probe module 2 or the tool, the tool setting elastic member 44 is compressed, and the tool setting long pin shaft 431 slides relative to the sliding sleeve 47, driving the conductive seat 434 to move, releasing the contact state between the conductive seat 434 and the trigger circuit board 42, thereby generating an electrical signal to achieve triggering.

[0046] See also Figure 3As another specific embodiment of the tool setting measuring device provided by the present application, the sliding assembly 43 also includes a flexible sealing sleeve 435 connected between the tool setting seat 432 and the sliding sleeve 47, and a tool setting cap 436 connected to the tool setting seat 432; a lifting and lowering groove 4116 is provided on the hollow inner shell 411, and one end of the tool setting cap 436 away from the tool setting seat 432 is located in the lifting and lowering groove 4116; the flexible sealing sleeve 435 surrounds the tool setting elastic member 44 and the tool setting long pin 431, and the tool setting cap 436 surrounds the flexible sealing sleeve 435. That is, the tool setting cap 436 can cover most of the structure of the sliding assembly 43, and the parts, grooves and screws on the hollow shell are not easily exposed, thereby ensuring the aesthetics of the tool setting module 4.

[0047] See also Figure 3 and Figure 5 As another specific embodiment of the tool setting measuring device provided by the present application, a light slot 4117 is provided on the hollow inner shell 411, and a ring indicator light cover 48 is provided in the light slot 4117; a light-emitting element facing the ring indicator light cover 48 is provided on the main control circuit board 45; and the tool setting seat 432 is threadedly connected with the tool setting long pin 431.

[0048] See also Figure 3-Figure 4 As another specific embodiment of the tool setting measuring device provided by the present application, the sliding assembly 43 also includes a short tool setting pin 437 installed on the sliding sleeve 47, and the conductive seat 434 is slidably connected to the short tool setting pin 437 to ensure the stability of the conductive seat 434 when sliding; a limit switch 451 is provided on the main control circuit board 45, which is directly opposite to the conductive seat 434. When the conductive seat 434 descends to a large enough position, the limit switch 451 is triggered to prevent the conductive seat 434 from moving excessively and contacting the main control circuit board 45; a cone head set screw 438 is provided between the long tool setting pin 431 and the conductive seat 434, and the conductive seat 434 can be firmly installed on the long tool setting pin 431 and is not easy to loosen.

[0050] See also Figure 6-Figure 7As another specific embodiment of the tool setting measuring device provided by the present application, the probe housing 21 includes an upper shell assembly 211, a threaded pin 212 connected to the upper shell assembly 211, a lower shell assembly 213 connected to the upper shell assembly 211, and a probe elastic member 214 connected to the upper shell assembly 211; the probe 22 is slidably mounted on the lower shell assembly 213 and connected to the probe elastic member 214; the elastic coefficient of the probe elastic member 214 is greater than the elastic coefficient of the tool setting elastic member 44. Therefore, when the probe 22 contacts the tool setting module 4, it can drive the sliding assembly 43 to move and trigger the trigger circuit board 42, while the probe 22 itself does not move, thereby ensuring the accuracy of the Z value data. For example, the force for triggering the tool setting elastic member 44 is 1.5-2N, and the force for triggering the probe elastic member 214 is 3.5-4N.

[0051] See also Figure 6-Figure 7 As another specific embodiment of the tool setting and measuring device provided in the present application, an upper circuit board 2111 is provided in the upper shell component 211, and a lower circuit board 2131 is provided in the lower shell component 213; a probe 2132 is provided between the upper circuit board 2111 and the lower circuit board 2131 to ensure contact between the two.

[0052] See also Figure 7-Figure 8 As another specific embodiment of the tool setting and measuring device provided by the present application, a three-hole seat 2134 is provided between the probe elastic member 214 and the probe needle 22, and three probe short pins 2135 are inserted on the three-hole seat 2134. A contact group 23 is provided on the lower circuit board 2131, and the contact group 23 includes two spherical contacts 231 arranged at intervals, and each probe short pin 2135 is located between the two spherical contacts 231; a cylindrical head screw 24 and an adjusting screw 25 are provided on the lower shell assembly 213; the lower circuit board 2131 is installed on the lower shell assembly 213 by the cylindrical head screw 24, and the adjusting screw 25 abuts against the side of the lower circuit board 2131 facing away from the spherical contact 231.

[0053] That is, the lower circuit board 2131 is mounted on the lower shell assembly 213 by means of a cylindrical screw. When the concentricity of the stylus 22 of the probe module 2 needs to be adjusted (so that the stylus 22 is located on the axis of the probe module 2), one or more of the multiple (for example, three) adjusting screws 25 are rotated and adjusted so that the adjusting screws 25 abut against the lower circuit board 2131 and the lower circuit board 2131 is partially moved a short distance. Then, the lower circuit board 2131 adjusts the state of the stylus short pin 2135 through two spherical contacts 231, and then adjusts the state of the three-hole seat 2134, and finally adjusts the state of the stylus 22 connected to the three-hole seat 2134, and adjusts the concentricity of the stylus 22. The cooperation of the three stylus short pins 2135 and the spherical contacts 231 can fully adjust the direction of the stylus 22 when the lower circuit board 2131 moves, and adjust the concentricity of the stylus 22.

[0054] See also Figure 7-Figure 8 As another specific embodiment of the tool setting measuring device provided by the present application, the probe housing 21 includes a protective cover 215 connected to the upper shell component 211, and a plurality of mounting grooves are provided on the protective cover 215, and mounting posts (which may have barbs) are provided in the mounting grooves, and a reset spring 216 is provided on the mounting post, and the reset spring 216 abuts against the probe short pin 2135. On the one hand, when the lower circuit board 2131 moves and drives the probe short pin 2135 to move too far through the spherical contact 231, the reset spring 216 can press the probe short pin 2135 to reset to avoid getting stuck. At the same time, when the tolerance of the probe elastic member 214 is large, the use of a shorter probe elastic member 214 requires the use of a gasket to raise the lower shell circuit board. At this time, the probe short pin 2135 compresses the reset spring 216 to form a small spring pressure to compensate for a certain probe trigger force (to prevent the probe 22 from loosening easily).
