Description

Technical Field

[0001] The invention relates to the technical field of tool measurement, and in particular to an adaptive automatic tool locking and measuring integrated machine. Background Art

[0002] Due to the fierce market competition, processing plants in the CNC machining industry are in urgent need of improving production efficiency and achieving cost reduction and efficiency improvement. In the use of CNC tools, in addition to measuring the length and contour dimensions of the tools in advance, there are also very high requirements for the tool runout. Excessive tool runout will lead to abnormal part processing dimensions and increased tool loss.

[0003] At present, the common method of measuring tool runout is to manually clamp the tool holder on the tool holder, blow off the iron filings and dust on the tool holder, then place the tool on the tool holder and lock it. After the tool is locked, install it in the tool presetter to measure the tool runout value. Since the locking torque of the tool and the tool holder is too large or too small, it will affect the tool runout value. Therefore, when the tool runout value is unqualified, it is necessary to manually remove the tool from the tool holder and re-clamp it, and then measure the tool runout value, and repeat this process. In the above process, when the measured tool runout value is unqualified, too many manual interventions are required, resulting in low measurement efficiency. Summary of the invention

[0013] When the runout value of the tool measured by the optical measurement component is unqualified, the processor sends a control instruction to the controller to control the locking device to loosen the tool and the tool holder, and the processor calls the torque again within the locking torque range and sends a control instruction to the controller to control the locking device to re-lock the tool and the tool holder, so that the optical measurement component can measure the runout value of the tool again until the runout value of the tool is qualified.

[0014] Furthermore, the tool locking and measuring integrated machine also includes an image acquisition card, which is electrically connected to the processor, and the image acquisition card is electrically connected to the optical recognition device and the optical measurement component respectively.

[0015] Furthermore, the processor is integrated with an algorithm for calculating the jitter value and determining whether the jitter value is qualified.

[0016] Furthermore, the torque first called by the processor is the minimum value of the locking torque range, and the torque re-called by the processor is greater than the torque called last time.

[0017] Furthermore, the tool locking and measuring integrated machine also includes a button, and the button is used to control the start and stop of the tool locking and measuring integrated machine with one button.

[0018] Furthermore, the processor is also electrically connected to an alarm. When all the values ​​within the locking torque range have been called up and the jump value is still unqualified, the alarm sounds an alarm.

[0026] 3. When the runout value is unqualified, the re-adopted torque is larger than the previous one, which avoids damage to the tool and affects the runout value due to excessive torque. BRIEF DESCRIPTION OF THE DRAWINGS

The lower end surface of the first boss 123 is vertically abutted against the upper end surface of the second boss 124. A pair of first grooves 125 that are symmetrical about the center are provided on the outer wall of the connecting ring 104, wherein the second boss 124 is matched with the first groove 125, and the lower surface of the first boss 123 is abutted against the upper surface of the connecting ring 104, which is used to limit the connecting ring 104.

In addition, the first display screen 16 is electrically connected to the processor 51 for displaying the real-time locking torque of the tool 60.

[0060] The processor 51 is electrically connected to the second camera 331 for processing the image to obtain the jitter value of the tool 60 and determine whether the jitter value meets the preset standard. Specifically, the image acquisition card 52 is electrically connected between the second camera 331 and the processor 51, and the image acquisition card 52 is used to convert the image of the tool 60 taken by the second camera 331 into a digital signal and transmit it to the processor 51. The processor 21 is integrated with an algorithm for processing the image, and the algorithm can obtain the jitter value and determine whether the jitter value is qualified.

[0061] The tool lock measuring machine also includes a printer 56, a second display screen 57 and an alarm 58. The printer 56 is electrically connected to the processor 51 and is used to print qualified data into labels, which is convenient for subsequent use and saves time. The second display screen 57 is electrically connected to the processor 51 and is used to display the runout value of the tool 60. The alarm 58 is electrically connected to the processor 51, and when the obtained runout value is unqualified, the alarm 58 alarms.

[0062] Reference again Fig.12 When the measuring instrument of the present invention is measuring, the first step is to lock the tool. First, the first camera 21 takes a picture of the tool 60. The static image taken is uploaded to the processor 51 through the first image acquisition card 52 for identification. The processor 51 calls the minimum value in the corresponding locking torque range according to the identified specification parameters of the tool 60, and sends a command to the controller 50 to control the lifting cylinder 110 to pull down the locking assembly 10. The locking box 101 immediately starts to rotate inside. After contacting the rotating drive device 4, the fourth boss 127 is stuck in the third groove 410 and continues to rotate until the third boss 126 is stuck in the second groove 615 of the locking nut 610. The locking nut 610 is subjected to torsion and starts to lock until the called torque is reached. Then, at this time, the locking assembly 10 stops rotating, and the lifting cylinder 110 pushes the locking assembly 10 upward to the first standby position.

[0063] In the second step, after the locking assembly 10 returns to the first standby position, the first magnetic switch 17 detects the first signal indicating that the locking assembly 10 returns to the first standby position, and transmits the first signal to the processor 51. The controller 50 controls the rotation drive device 4 to drive the locked tool 60 to rotate.

[0064] The third step is to measure the tool. After receiving the first signal, the processor 51 sends a signal to the second camera 331, the light source 332, the second motor 310 and the third motor 320 according to the preset program. The processor 51 transmits the signal to the light source 332 through the D / A conversion card 54 and controls the light source 332 to turn on. The I / O input and output card 53 transmits the instruction to the controller 50, the controller 50 controls the second motor 310 to rotate, and the second slider 312 drives the Z-direction drive component 32 to move along the X direction; the I / O input and output card 53 transmits the instruction to the controller 50, the controller 50 controls the third motor 320 to rotate, and the third slider 322 drives the measuring component 33 to move along the Z direction. The image captured by the second camera 331 is transmitted to the processor 51 by the second image acquisition card 55, and the processor 51 calculates the runout of the tool 60 and other related information and transmits it to the computer, which is displayed on the display screen 57. After the measurement is completed, the linear drive device 30 returns to the second standby position under the operation of the second motor 310 and the third motor 320. After reaching the second standby position, the first travel switch 34 detects a second signal indicating that the linear drive device 30 returns to the second standby position, and transmits the second signal to the processor 51 .

[0065] If the measured jitter value meets the preset requirements, the processor 51 sends a signal to the printer 56, and the printer 56 prints out the measured jitter value and other parameters.

[0066] If the measured runout value does not meet the preset requirements, the controller 50 controls the rotary drive device 4 to stop rotating. The processor 51 reselects the torque within the locking torque range, and the reselected torque is slightly increased compared to the last time, and sends an instruction to the controller 50 to control the locking device 1 to start again, move down to the handle 61 again, loosen the locking nut 610, and then lock it again according to the reselected torque, and return to the first standby position after the locking is completed. The processor 51 sends a start signal to the measuring device 3 to measure again until the measured runout value is qualified. Among them, the torque selected by the processor 51 each time is within the locking torque range. If all torques within the locking torque range are called and the measured runout value still does not meet the preset requirements, the alarm 58 will sound an alarm, and subsequent manual processing will be performed.

[0067] An adaptive automatic tool locking and measuring integrated machine according to an embodiment of the present invention controls the start and stop of the locking mechanism and the measuring mechanism by one button 8, without multiple switches, and is easy to operate. By simultaneously controlling the locking mechanism and the measuring mechanism in the processor 51, the tool 60 with unqualified runout value can be clamped and measured multiple times within the preset torque range, reducing manual intervention and saving labor costs. By using the controller 50 to control the locking assembly 10 to tighten the tool 60 and the handle 61, no manual intervention is required, ensuring that the locking torque is always within a reasonable range and improving accuracy. By presetting the locking torque required for different tools 60 in the processor 51, and identifying the diameter of the tool 60 and the type of the handle 61 according to the image taken by the first camera 21, the corresponding locking torque is selected, thereby improving accuracy and precision. By setting a connecting ring 104 of elastic material between the worm gear 102 and the locking nut 610, wear is reduced. By installing the first door curtain 14 and the second door curtain 15 on the housing 13, dust ingress is reduced, and the first drive assembly 11 and the first motor 100 inside the housing 13 are dust-proofed, thereby improving accuracy and service life. By installing the optical recognition device 2 on the side of the base 7 and aligning it with the tool 60, the image taken by the first camera 21 can be clear, and the locking device 1 and the measuring device 3 will not be interfered with.

[0068] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
