[0001] The utility model belongs to the technical field of tool setting devices, and particularly relates to a contact tool setting device for a numerically controlled machine tool with cable communication. Background Technique

[0003] The existing tool setting devices are usually installed in the machining area of numerically controlled machine tools. The continuous vibration, chip impact and coolant injection generated during machining of the machine tool will have a huge impact on the use state and service life of the tool setting device. Therefore, a contact tool setting device for a numerically controlled machine tool with cable communication is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a contact tool setting device for a numerically controlled machine tool with cable communication to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A contact tool setting device for a numerically controlled machine tool with cable communication, including a driving mechanism and a protection component. The protection component includes a protective cover and a convex block. The output shaft of the driving mechanism is connected to the protective cover. A convex block is connected inside the protective cover. The back surface of the convex block is lapped with a transfer piece. A tool setting block is connected inside the transfer piece. A tool is lapped on the upper surface of the tool setting block. The outside of the transfer piece is slidably connected with a housing. The back surface of the transfer piece is connected to a support frame. The front surface of the support frame is lapped with a sensor. The sensor is clamped inside the housing. The back surface of the support frame is connected to the housing through a spring. A detection module is clamped inside the housing. The detection module is connected to the sensor.

[0006] As a preferred implementation manner, the driving mechanism is set as a swing cylinder or a motor.

[0007] As a preferred implementation manner, the driving mechanism is connected to the front surface of the housing.

[0008] As a preferred implementation manner, the tool setting block is arranged inside the protective cover.

[0009] As a preferred implementation manner, the support frame is slidably connected inside the housing, and the support frame is arranged between the detection module and the sensor.

[0010] As a preferred implementation manner, the housing is connected to the machine tool body through bolts.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a shield, a protrusion, an adapter, a support frame, a sensor and a detection module. When the protection component is closed to cover the tool setting block and pushes the support frame to separate from the sensor, the shield can shield the chips and the coolant, making it difficult for the chips and the coolant to impact the sensitive part of the tool setting device, and also preventing the influence of machine tool vibration on the sensor life. The protection component is opened during tool measurement to expose the tool setting block, and at the same time the support frame and the tool setting block are reliably reset, the tool setting device stops outputting the trigger signal, and the machine tool confirms that the protection component is opened. The tool setting device can then perform the tool setting operation and complete the automatic tool setting (i.e., online tool detection), thereby ensuring the cleanliness of the tool setting block surface and the reliability of the tool setting.

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are within the scope of protection claimed by the present invention.

[0021] See also Figures 1-5, the present utility model provides a contact type tool setter for a cable communication numerical control machine tool, which includes a driving mechanism 1 and a protection component 2. The protection component 2 includes a shield 201 and a bump 202. The output shaft of the driving mechanism 1 is connected to the shield 201. The driving mechanism 1 is set as a swing cylinder or a motor. By setting the shield 201, the shield 201 that rotates outside the tool block can block the chips;

[0022] The driving mechanism 1 is set as a swing cylinder or a motor. A bump 202 is connected inside the shield 201. The back surface of the bump 202 is lapped with the adapter 10. By setting the bump 202, the rotating shield 201 can push the support frame 4 to make a micro displacement through the bump 202 and the adapter 10;

[0023] An adapter 10 is connected with a tool block 3 inside. The tool block 3 is arranged inside the shield 201. The upper surface of the tool block 3 is lapped with a tool 8. The outside of the adapter 10 is slidably connected with a housing 9. The driving mechanism 1 is connected to the front surface of the housing 9. The back surface of the adapter 10 is connected to the support frame 4. The front surface of the support frame 4 is lapped with a sensor 5. The sensor 5 is clamped inside the housing 9. The back surface of the support frame 4 is connected to the housing 9 through a spring 6. By setting the spring 6, after the bump 202 is separated from the adapter 10, the support frame 4 can contact the sensor 5 under the action of the spring 6 elasticity, and the moving support frame 4 can drive the tool block 3 to reset through the adapter 10;

[0024] A detection module 7 is clamped inside the housing 9. The detection module 7 is connected to the sensor 5. By setting the sensor 5 and the detection module 7, the sensor 5 and the detection module 7 can cooperate with each other to detect the micro displacement of the tool block 3 through the support frame 4 and the adapter 10;

[0025] The support frame 4 is slidably connected inside the housing 9. The support frame 4 is arranged between the detection module 7 and the sensor 5. The housing 9 is connected to the machine tool main body 11 through bolts.

[0026] The working principle and usage process of the present utility model: The working driving mechanism 1 drives the shield 201 to rotate. The shield 201 moves away from outside the tool block 3. At this time, the shield 201 opens, exposing the tool block 3. At this time, the support frame 4 resets under the action of the spring 6 elasticity. Then the detection module 7 can confirm that the shield 201 is opened through the data detected by the sensor 5 and execute the tool setting program to complete the automatic tool setting, that is, the on-line detection of the tool 8;

[0027] Since the tool block 3 is connected to the support frame 4 and the support frame 4 is pressed on the sensor 5 by the spring 6, when the tool 8 contacts the tool block 3 and generates a micro displacement, the moving tool block 3 transmits the micro displacement to the sensor 5 through the adapter 10 and the support frame 4. After the detection module 7 detects the parameter change of the sensor 5, it outputs a trigger signal to access the machine tool;

[0028] When the tool setting is completed, the driving mechanism 1 drives the shield 201 to rotate. At this time, the rotating shield 201 moves outside the tool setting block 3, and the rotating shield 201 drives the convex block 202 to contact the adapter 10 and then pushes the adapter 10 to displace. The displaced adapter 10 presses the support frame 4 inward, and then completely disengages from the sensor 5. The detection module 7 continuously sends out trigger signals. After the machine tool confirms, the tool setting program ends and subsequent processing is executed. At this time, the tool setting block 3 is completely shielded, avoiding damages such as chip impact and contamination. Moreover, because the support frame 4 is pressed inward and completely disengages from the sensor 5, it makes it difficult for the vibration of the machine tool to cause damages such as abrasion and impact of the support frame 4 on the sensor 5.

[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
