Description

Technical Field

[0001] The utility model relates to the technical field of tool wear measuring devices, in particular to a tool wear detector. Background Art

[0002] In the field of mechanical processing, tool wear is a key factor affecting machine processing production efficiency, product quality and production costs. After long-term use, tool wear or breakage will not only affect the processing accuracy, but may also cause damage to product quality and machine tools. Therefore, accurately detecting the wear state of the tool is crucial to maintaining the stability of the mechanical processing process and product quality.

[0003] With the rapid development of the machining industry and the improvement of automation level, modern machining has increasingly higher requirements for tool wear detection speed and tool wear detection accuracy. Traditional tool detection methods mainly rely on manual observation and contact measurement tools, such as contact measurement using mechanical contact probes. Although this method can achieve a certain measurement effect, it has many limitations. First, the probe is prone to wear and breakage during use, which directly affects the machining accuracy of the machined parts. Secondly, the contact measurement tool is complicated to operate and takes a long time to adjust, which increases non-machining time, reduces overall machining efficiency, and cannot meet the detection needs of various complex working conditions.

[0004] 1. Problems to be solved

[0005] The technical problem to be solved by the utility model is to provide a tool wear detector in view of the current status of the prior art.

[0006] (II) Technical solution

[0007] The utility model is implemented through the following technical scheme: the utility model proposes a tool wear detector, comprising: a shell, on which a blue laser emission port and a blue laser receiving port are arranged; a blue laser transmitter, a blue laser receiver, a detector control unit and a built-in battery are installed inside the shell, and a blue laser diode is arranged inside the blue laser transmitter; the detector control unit is connected with the blue laser transmitter and the blue laser receiver; the built-in battery provides temporary power for the blue laser transmitter, the blue laser receiver and the detector control unit; the detector control unit comprises a manual push switch, a circuit board, a memory, a processor, and the processor is equipped with an external output module and an external input module; the manual push switch is arranged above the shell, and the shell is mounted on a mounting block, and a safety quick-connect connector is arranged on the mounting block; the safety quick-connect connector is used to connect with other devices to provide power input and data transmission; an air blowing unit is installed on the mounting block, and the air blowing unit comprises a rotating air outlet nozzle and a pneumatic quick-connect connector; the air blowing unit is used to remove debris and coolant attached to the tool when the tool is not working.

[0008] By adopting the above technical solution, a blue laser can be emitted through a blue laser emitter through a blue laser emission port. When the laser path does not pass through the tool head, the blue laser is received by a blue laser receiver through a blue laser receiving port. At this time, the blue laser receiver generates a signal of receiving the blue laser and sends it to the detector control unit; when the laser path passes through the tool head, the blue laser will not be received by the blue laser receiver through the blue laser receiving port. At this time, the blue laser receiver generates a signal of not receiving the blue laser and sends it to the detector control unit. The detector control unit is provided with a circuit board, a memory, and a processor to complete the processing and storage of the collected information and the judgment and analysis of the tool wear. In addition, the device can work independently without being attached to other devices through a built-in battery and a manual press switch. A blowing unit is also designed in the device to remove debris and coolant attached to the tool. Combining it with the scheme of using the short wavelength and extremely fast propagation speed of the blue laser to improve the diffraction effect of the laser and optimize the geometric shape of the laser beam, the detection accuracy of the tool wear is greatly improved, and a fast and accurate detection effect is achieved. Through the above technical solution, the device can not only improve product quality, but also reduce time and speed up machining production efficiency. In addition, it does not require manual tool setting to reduce manual labor, save labor costs, and avoid product scrapping and collision caused by manual tool setting errors.

[0009] Furthermore, a magnet is provided at the bottom of the housing; the housing is mounted on the mounting block by magnetic attraction or bolts. A connecting block is installed at the bottom of the mounting block, and a thread is provided in the connecting block; the thread is used to firmly fix the mounting block in a machine tool or other equipment.

[0010] By adopting the above technical solution, the housing can ensure that the internal components are not affected by the external environment. The magnet is located at the bottom of the housing, which allows the housing to be quickly and conveniently installed on a mounting block with a magnetic or magnetizable surface by magnetic force, and when the magnetic attraction method is not applicable, a bolt connection can be used to ensure a stable connection between the housing and the mounting block. The connecting block allows the device to be connected to the corresponding holes or threaded holes on the machine tool or other equipment by bolts, nuts or other fasteners, so as to achieve flexible installation and meet the needs of various environments.

[0011] Furthermore, the pneumatic quick-connect connector is connected to the air source drive assembly through an air pipe. The air source drive assembly includes an air pressure regulating valve, an air source supply device, and a pneumatic actuator controller. The pneumatic actuator controller is connected to the circuit board.

[0012] By adopting the above technical solution, the circuit board can adjust the angle of the rotating air outlet nozzle to align the tool for cleaning according to the information collected by the blue laser receiver, and send instructions to the pneumatic actuator controller and the air pressure regulating valve to start ventilation and increase or decrease the air outlet speed.

[0013] Furthermore, a chip for processing signals is installed inside the circuit board, and processing software is installed inside the chip.

[0014] By adopting the above technical solution, the chip can exchange information with the external output module and the external input module on the processor, and through the processing software inside the chip, intelligent control of the device can be achieved through software, thereby improving the user experience.

[0015] Furthermore, when the tool is installed in the machine tool, the tool is moved up and down, and within the entire horizontal height range of the tool head, the horizontal heights of the blue laser emission port and the blue laser receiving port can be flush with the horizontal height of the tool head.

[0016] By adopting the above technical solution, it can be ensured that after the tool stops rotating, the dimensional information of each horizontal height of the tool head can be accurately collected.

[0017] (III) Beneficial effects

[0018] 1. The utility model uses low-wavelength blue laser to detect tool wear to reduce the diffraction effect of laser, improve the detection size accuracy and detection speed of tool head, improve the efficiency of tool wear detection, reduce labor costs, and avoid product scrapping and collision caused by manual tool setting errors. At the same time, by installing the air blowing component, the tool is cleaned before each laser detection to avoid the tool wear detection accuracy being affected by the removal of debris and coolant attached to the tool.

[0019] 2. The utility model detects tool wear through a series of identification and information processing steps using a blue laser, and ensures that the tool wear is in a qualified state, so that the quality of the processed product is guaranteed; it avoids the waste of subsequent processing time and costs due to excessive wear, which leads to the discovery of product dimensions exceeding the expected range in subsequent processes. In addition, the device can be used independently through the chip built-in software or manually pressing the switch, and can be applied to many occasions other than CNC machine tools, making the device widely applicable.
