Description

Technical Field

[0001] The present invention relates to the technical field of tool changing mechanisms, and in particular to a cam timing angle detection device and a detection method for a tool magazine tool changing mechanism. Background Art

[0002] With the rapid development of the machining industry, the demand for machine tools is increasing, and the demand for tool magazines, which are the functional components of machine tools, is also increasing accordingly.

[0003] The core component of the tool magazine is the tool changing mechanism, which mainly relies on the coordinated action of the internal arc cam and end face cam to complete the tool changing action.

[0004] In the existing technology, most tool magazine manufacturers have the ability to design curved cams and end cams, but lack the corresponding processing technology, so they usually rely on specialized outsourcing factories for processing. Because cam detection equipment is mostly imported, expensive, difficult, and time-consuming to detect, most companies lack the detection capabilities and are unable to accurately determine whether the timing angle of the cam components processed by the outsourcing factory meets the design requirements. If the timing angle of the cam component of the tool changing mechanism deviates from the designed angle, the electrical timing sensing signal wheel of the tool changing mechanism designed according to the theoretical value of the cam design timing angle will not match the tool changing timing of the tool changing mechanism, thereby affecting the normal operation of the machine tool's tool changing action.

[0005] Therefore, how to provide a cam timing angle detection device and a detection method for a tool magazine tool changing mechanism is a technical problem that those skilled in the art urgently need to solve. Summary of the Invention

[0069] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0070] The following combination Figure 1 The present invention describes a cam timing angle detection device for a tool magazine tool changer. It is used to detect the timing angle of a cam in the tool changer 8. The cam is powered by a motor and connected to a signal wheel spindle. The cam drives the rotation and displacement of a manipulator. The detection device includes a bracket 1, a connecting rod 3, an angle scale 2, a pointer 5, a manipulator 7, and a dial indicator 9.

[0071] The tool changing mechanism 8 is mounted on the bracket 1, ensuring the stability and reliability of the device. The connecting rod 3 is mounted on the signal wheel spindle at the rear end of the tool changing mechanism 8, and the angle dial 2 is mounted on the connecting rod 3. When a wrench is used to rotate the motor, the connecting rod 3 and the angle dial 2 can be driven to rotate together through the transmission system inside the tool changing mechanism 8. The pointer 5 is set on the housing of the tool changing mechanism 8, and the tip of the pointer 5 points to the angle scale on the angle dial 2. The dial indicator 9 is used to contact the manipulator 7, and the numerical change caused by the manipulator 7 touching the dial indicator 9 is used to judge the start and end of the cam timing angle action of the tool changing mechanism 8.

[0072] Specifically, the pointer 5 is fixed on the magnet 4, and the magnet 4 is fixed on the tool changing mechanism 8. In addition, in order to provide a placement platform for the dial indicator 9, a base 6 is also provided.

[0073] Furthermore, when the cam of the tool change mechanism 8 completes the five compound actions of locking the knife, pulling out the knife, rotating 180 degrees, inserting the knife, and returning to the original position, it mainly relies on the combination of the arc cam and the end face cam inside the tool change mechanism. The arc cam and the end face cam each have a specific timing angle, of which the arc cam is responsible for the rotation of the manipulator 7, and the end face cam is responsible for the up and down movement of the manipulator 7. In order to detect the cam timing angle of the tool change mechanism 8, it is necessary to decompose the tool change action and refer to the different functions of the two cams. Figure 2 , and divided them into two groups for testing respectively.

[0074] The following describes the cam timing angle detection method of the tool magazine tool changing mechanism provided by the present invention. The cam timing angle detection method of the tool magazine tool changing mechanism 8 described below and the cam timing angle detection device of the tool magazine tool changing mechanism described above can correspond to each other.

[0075] The detection grouping method is as follows:

[0076] First, the cambered cam is responsible for the timing angle detection of the knife locking, 180° rotation and return to the original position.

[0077] Secondly, the timing angle detection of the knife pulling and inserting actions that the end face cam is responsible for is completed.

[0078] The core idea of ​​the detection method is to reasonably arrange the contact position between the dial indicator 9 and the manipulator 7, and use the value change caused by the manipulator 7 touching the dial indicator 9 to determine the start and end of the cam timing angle action of the tool changing mechanism 8;

[0079] Observe the indicated angle of the pointer 5 on the angle scale 2, read and record the corresponding real-time angle value;

[0080] By comparing the real-time angle value with the designed angle, it can be determined whether the cam timing angle is qualified.

[0081] Specifically, the detection method of the embodiment of the present invention includes:

[0082] Step 1: If Figure 3a and Figure 3b As shown, the tool changing mechanism includes the detection of the tool changing mechanism cam timing angle home angle E:

[0083] Before arranging the contact position between the dial indicator 9 and the manipulator 7, be sure to confirm that the manipulator 7 is parallel to the bottom side of the tool changer 8, and then perform the in-situ detection of the cam timing angle of the tool changer 8. The specific steps are as follows:

[0084] (1) Adjust the angle dial 2 to ensure that the pointer 5 points to the 0° mark on the angle dial 2;

[0085] (2) Install the dial indicator 9 on the outside of the housing of the tool changing mechanism 8, ensuring that the probe of the dial indicator 9 is in close contact with the side end surface of the manipulator 7. At this time, the dial indicator 9 should display a reading;

[0086] (3) Use a wrench to turn the motor clockwise until the manipulator 7 starts to move. At this time, the reading of the dial indicator 9 changes. Stop turning the motor immediately and record the angle P1 indicated by the pointer 5 on the angle dial 2.

[0087] (4) Then use the wrench to rotate the motor counterclockwise until the manipulator 7 starts to move again and the reading of the dial indicator 9 changes. Immediately stop rotating the motor and record the angle P2 indicated by the pointer 5 on the angle dial 2;

[0088] (5) The calculated angle is E = (360° - P2 + P1) / 2;

[0089] (6) Continue to use the wrench to rotate the motor clockwise until the manipulator 7 starts to move and the reading of the dial indicator 9 changes. Immediately stop rotating the motor; then adjust the angle dial 2 so that the pointer 5 points to the E value position calculated on the angle dial 2.

[0090] The second step is Figure 4a and Figure 4b As shown, continue to detect the tool position of the cam timing angle of the tool changing mechanism 8, that is, Figure 2 The specific steps for detecting the middle angle F are as follows:

[0091] (1) Use a wrench to rotate the motor clockwise. Then the manipulator 7 will start to rotate counterclockwise. When the manipulator 7 stops rotating, stop rotating the motor.

[0092] (2) Place the dial indicator 9 on the housing of the tool changing mechanism 8, and make sure the probe of the dial indicator 9 contacts the side end face of the manipulator. At this time, the dial indicator 9 should display the reading;

[0093] (3) Use a wrench to repeatedly rotate the motor clockwise and counterclockwise until you find a position where the reading displayed by the dial indicator 9 is stable and remains unchanged. Stop rotating the motor and record the value indicated by the pointer 5 on the angle dial 2. The value is the angle F.

[0094] The third step is to continue the rotation detection of the tool changing mechanism cam timing angle. The rotation angle is 180°, that is, starting from the starting angle. The specific steps are as follows:

[0095] (1) Based on the detection of the tool position F of the cam timing angle of the tool changing mechanism 8, use a wrench to rotate the motor clockwise until the value displayed on the dial indicator 9 changes, indicating that the manipulator 7 starts to rotate counterclockwise. At this time, stop manually rotating the motor;

[0096] (2) Record the angle value indicated by pointer 5 on the angle scale 2, which is the reading of angle G.

[0097] The fourth step is as follows Figure 5a and Figure 5b As shown, the tool changing mechanism 8 cam timing angle continues to rotate 180 degrees to complete the angle detection, that is, Figure 2 The specific steps for detecting the angle H are as follows:

[0098] (1) Remove the dial indicator 9 and use a wrench to rotate the motor clockwise. At this time, the manipulator 7 rotates counterclockwise. After the manipulator 7 stops rotating, stop rotating the motor.

[0099] (2) As shown in FIG5 , the probe of the dial indicator 9 is brought into close contact with the side end surface of the manipulator 7 so that the dial indicator 9 can display the reading;

[0100] (3) Use a wrench to repeatedly rotate the motor clockwise and counterclockwise until a position is found where the reading on the dial indicator 9 stabilizes and remains unchanged; at this point, stop manually rotating the motor and record the value on the angle dial 2 indicated by the pointer 5. This value is the angle H.

[0101] The fifth step is to continue the operation of returning the cam timing angle of the tool changing mechanism 8 to the original position, that is, Figure 2 Detection of angle J, including:

[0102] (1) Based on the measured angle H, continue to use the wrench to rotate the motor clockwise until the value displayed on the dial indicator 9 changes, indicating that the manipulator 7 starts to rotate clockwise. At this time, stop manually rotating the motor;

[0103] (2) Record the angle value indicated by pointer 5 on angle scale 2, i.e. angle J;

[0104] The sixth step is to continue the reset detection of the cam timing angle of the tool changing mechanism 8, that is, Figure 2 The specific steps for detecting the angle K shown in are as follows:

[0108] The seventh step is to continue to detect the starting angle of the tool change mechanism 8 cam timing angle of the tool withdrawal position, that is, Figure 2 The specific steps for detecting the angle Q shown in the figure are as follows:

[0109] (1) Repeat the first step to complete the detection of the original angle E of the cam timing angle of the tool changing mechanism 8;

[0110] (2) Remove the dial indicator 9 and use a wrench to rotate the motor clockwise until the manipulator 7 starts to move downward. At this time, stop manually rotating the motor;

[0112] (4) Use a wrench to repeatedly rotate the motor clockwise and counterclockwise until you find a position where the reading displayed by the dial indicator 9 stabilizes at a fixed value. Stop manually rotating the motor and record the value on the angle dial 2 that the pointer 5 points to, which is the angle Q.
