Description

Technical Field

[0001] The present invention relates to the technical field of lathe machining detection, and specifically to a numerical control lathe tool radius laser detection device with anti-interference function. Background Technique

[0002] Lathe machining is a part of machining. On a lathe, drills, reamers, broaches, taps, threading dies, knurling tools, etc. can also be used for corresponding machining. Lathe machining has low difficulty and strong plasticity, and the weight of the product is greatly reduced. The cooperation between the lathe and the lathe tool is indispensable. Therefore, the importance of the lathe tool is self-evident. Selecting the corresponding tool and performing reasonable machining can produce better products. Therefore, during the tool installation process, multiple factors need to be considered comprehensively.

[0003] In the traditional lathe machining process, the auxiliary time such as workpiece loading and unloading and tool adjustment accounts for a relatively long processing cycle time. Among them, tool adjustment is time-consuming and laborious, not easy to be accurate, and finally trial cutting is required. Once handled improperly, it will not only result in unqualified product machining, but also cause tool damage and serious faults of the lathe. Moreover, when there is a problem with the tool itself, it will also lead to improper installation. At this time, a device is needed to fully detect the radius of the tool and the state of the tool itself to ensure normal subsequent machining. Summary of the Invention

[0004] The purpose of the present invention is to provide a numerical control lathe tool radius laser detection device with anti-interference function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: The laser detection device includes a detection bracket, on which a tool holder is provided. The tool holder is slidably connected to the detection bracket. A detection motor and a tool mounting ring are provided on the tool holder. A locking assembly is provided inside the tool mounting ring, and the locking assembly is connected to the output end of the detection motor. A deflection motor is provided on the detection bracket, and a detection lamp holder is provided on the output end of the deflection motor. A first laser and a second laser are respectively provided on the detection lamp holder. A recorder and a laser converter are also provided on the detection bracket. The first laser and the second laser are respectively electrically connected to the laser converter through wires. A signal receiver is also provided on the detection lamp holder, and the signal receiver is electrically connected to the recorder through a wire. When installing a lathe tool, it is necessary to ensure the integrity and good condition of the tool. At the same time, when installing the tool, it is also necessary to ensure the accuracy of the tool position. When detecting the tool, first install the lathe tool on the locking assembly, and then the lathe tool will enter between the first laser and the second laser. Subsequently, through the recorder and the laser converter, the working states of the first laser and the second laser are controlled. Then, the reflected laser will be received by the signal receiver and converted into an electrical signal and transmitted into the recorder. The recorder will obtain the situation of the laser reflection, thereby obtaining the self-state of the tool. At the same time, by adjusting the position of the tool holder, the tool can be scanned in all directions to obtain more complete tool data. The tool installed on the lathe can also pass through the detection lamp holder, and then be scanned, and finally the detection result is obtained.

[0006] Teeth are evenly arranged on the tool holder. An alignment motor is provided on the detection bracket, and a moving gear is provided on the output end of the alignment motor. The moving gear meshes with the teeth on the tool holder. An installation crank is rotatably connected to the tool holder, and the installation crank is connected to the locking assembly. When installing the tool, adjust the alignment motor, and the moving gear drives the tool holder to move to the corresponding position. Then, the tool holder is sent into the locking assembly, and the installation crank is rotated. The installation crank adjusts the diameter of the locking assembly so that the lathe tool is fully clamped for easy detection.

[0007] The locking assembly includes a locking ring, which is arranged inside the tool mounting ring. A plurality of locking plates are slidably connected inside the locking ring. An adjustment groove is respectively provided on each locking plate. An adaptive elastic piece is provided in the adjustment groove. An adjustment ball is provided in the adjustment groove, and the adjustment ball is rotatably connected to the adjustment groove. When the installation crank rotates, it will drive the locking ring to rotate through the teeth. The locking ring abuts against the locking plate, and the locking plate moves closer to the lathe tool. The adjustment groove on the locking plate will continuously move closer to the lathe tool until the adjustment ball is in contact with the lathe tool. The adjustment ball applies pressure to the adaptive elastic piece until the adjustment groove is completely fitted with the lathe tool. The adjustment ball can fully ensure the installation tightness of the lathe tool, and at the same time, it can also fully enable the lathe tool to obtain sufficient attitude adjustment.

[0008] The detection lamp holder includes a deflection frame and a deflection sub-frame. A detection box is provided on the detection bracket. The deflection frame and the deflection sub-frame are respectively rotatably connected to the detection box. Tooth teeth are respectively provided on the deflection frame and the deflection sub-frame. The first laser and the second laser are respectively provided on the deflection frame and the deflection sub-frame. Wire installation grooves are respectively provided on the deflection frame and the deflection sub-frame. The output ends of the first laser and the second laser face each other. When performing scanning detection, the first laser and the second laser work to emit laser of a specific frequency. The deflection frame and the deflection sub-frame are responsible for adjusting the postures of the first laser and the second laser. At the same time, the deflection frame and the deflection sub-frame can adopt an electrically lifted structure to adapt to lathe tools of various heights.

[0009] The output end of the deflection motor passes through the detection box and is rotatably connected to the detection box. A transmission gear and a reverse gear set are provided in the detection box. A deflection gear is provided on the output end of the deflection motor. The deflection gear meshes with the transmission gear and the reverse gear set respectively. Tooth teeth are respectively provided at the bottom ends of the deflection frame and the deflection sub-frame. The deflection frame and the deflection sub-frame are respectively meshed with the transmission gear and the reverse gear set. During the detection process, the deflection motor drives the deflection gear to rotate. The deflection gear transmits power to the transmission gear and the reverse gear set, so that the deflection frame and the deflection sub-frame can change postures, and the first laser and the second laser form a certain angle, and the running lathe tool can be locally detected. It can be known that in different directions, the deviation state of the tool running can be obtained, and the problem of missing tool detection during single detection can be avoided.

[0010] An adjustment ring is rotatably connected to the detection box. The transmission gear and the reverse gear set are respectively connected to the adjustment ring through brackets. A sliding groove is provided in the adjustment ring. The deflection frame and the deflection sub-frame are embedded in the sliding groove and are slidably connected to the sliding groove. A friction groove is provided in the detection box. The adjustment ring is in sliding contact with the friction groove. During the detection process, the transmission gear and the reverse gear rotate in the adjustment ring. At the same time, through the cooperation between the adjustment ring and the friction groove, the multi-angle deflection of the detection lamp holder can be performed, and various types of tools can be adapted.

[0011] A liquid coating component is arranged inside the tool mounting ring. The liquid coating component includes a liquid coating ring which is communicated with a supply tank through a conduit. A buffer cavity is arranged inside the liquid coating ring. A plurality of liquid coating ports are arranged on the inner ring of the liquid coating ring. A dispersion brush is respectively arranged on each liquid coating port and is communicated with the liquid coating port. During the detection process, for some minor defects, the data change detected by the laser is relatively small. At this time, when manually capturing or positioning, it will cause problems that cannot be accurately repaired. By filling the outer surface of the lathe tool with glue or diffusion liquid, the angle change of laser refraction can be increased, and the original change data can be enlarged. By utilizing the different gravitational forces of the defects on the liquid and the different masses of the absorbed glue, relatively minor defects can be directly located, providing sufficient convenience for subsequent maintenance personnel. At the same time, for the tool treated with glue coating, its anti-pollution degree will also be greatly weakened, reducing the detection error.

[0012] A plurality of equal-pressure ports are arranged on the dispersion brush. A resisting ball and a resisting elastic sheet are respectively arranged inside each equal-pressure port. The resisting ball is in sliding contact with the equal-pressure port, and the resisting ball is in sliding contact with the resisting elastic sheet. The diameter of the equal-pressure port is smaller than the diameter of the resisting ball. During the coating process, the coating medium will be communicated with the externally installed supply tank, so that the buffer cavity is filled with the coating medium and pressure is applied to the equal-pressure ports. Until the pressure of each equal-pressure port is consistent, the liquid at the equal-pressure port will simultaneously push open the resisting ball, so that the coating medium is fully and evenly diffused on the lathe tool, ensuring the uniformity of the medium and avoiding the problem of glue accumulation.

[0013] The detection bracket includes a support arm and a mounting base. The support arm is arranged on the mounting base. A lifting arm is slidably connected to the support arm. Locking ports are respectively arranged on the lifting arm and the support arm. Locking bolts are arranged inside the locking ports. The tool holder is slidably connected to the lifting arm. The detection motor body part is fixedly connected to the lifting arm. By adjusting the distance between the lifting arm and the support arm, the height of the detection bracket can be adjusted to adapt to lathe tools of various heights and also various installation positions during detection. After the adjustment is completed, it is locked by the locking bolt, and the locking bolt connects to the locking port, so that the positions between the lifting arm and the support arm are determined relative to each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The present invention adopts a structural component with multiple detection methods, which can not only detect the tool during the installation process, but also detect the tool separately. The detection results are more abundant, avoiding the problem of too long cycle during the installation process caused by a single failure. At the same time, this device also adopts an adaptive installation method, which can reduce the damage to the tool while ensuring the stability of the tool posture. The present invention also adopts a function with deflection detection, and by adjusting the angle and position of laser emission, more detection results can be obtained, reducing the omission problem caused by a single result. At the same time, the present invention also adopts a glue application component with data amplification. By evenly releasing the tool itself, the tool defects can be amplified. By cooperating with the laser, the obtained defect data will be more obvious. When used in combination with the original data, it provides sufficient convenience for the subsequent maintenance personnel, and can also accurately locate the defective parts.

[0026] Embodiment: As Figures 1-8As shown in the figure, the present invention provides a technical solution. The laser detection device includes a detection bracket 1, on which a tool holder 2 is arranged. The tool holder 2 is slidably connected to the detection bracket 1. A detection motor 3 and a tool mounting ring 4 are arranged on the tool holder 2.

A deflection motor 6 is arranged on the detection bracket 1, and a detection lamp holder 7 is arranged on the output end of the deflection motor 6. A first laser 8 and a second laser 9 are respectively arranged on the detection lamp holder 7. A recorder 10 and a laser converter 11 are also arranged on the detection bracket 1. The first laser 8 and the second laser 9 are respectively electrically connected to the laser converter 11 through wires. A signal receiver 12 is also arranged on the detection lamp holder 7, and the signal receiver 12 is electrically connected to the recorder 10 through a wire. When installing the lathe tool, it is necessary to ensure the integrity and good condition of the tool. At the same time, when installing the tool, it is also necessary to ensure the accuracy of the tool position. When detecting the tool, first install the lathe tool on the locking component 5. Subsequently, the lathe tool will enter between the first laser 8 and the second laser 9. Then, through the recorder 10 and the laser converter 11, the working states of the first laser 8 and the second laser 9 are controlled. Subsequently, the reflected laser will be received by the signal receiver 12 and converted into an electrical signal and transmitted into the recorder 10. The recorder 10 will obtain the situation of the laser reflection, thereby obtaining the self-state of the tool. At the same time, by adjusting the position of the tool holder 2, the tool can be scanned in all directions to obtain more complete tool data. The tool installed on the lathe can also pass through the detection lamp holder 7, and then be scanned, and finally the detection result is obtained.

When installing the tool, adjust the alignment motor 13. The moving gear 1301 drives the tool holder 2 to move. Move to the corresponding position, and then send the tool holder 2 into the locking component 5. Rotate the installation crank 1302, and the installation crank 1302 adjusts the diameter of the locking component 5 to fully clamp the lathe tool for easy detection.

[0028] The locking assembly 5 includes a locking ring 501 which is arranged inside the tool mounting ring 4. A plurality of locking plates 502 are slidably connected inside the locking ring 501. Each locking plate 502 is respectively provided with an adjustment groove 503. An adaptive elastic piece 504 is arranged inside the adjustment groove 503. An adjustment ball 505 is arranged inside the adjustment groove 503. The adjustment ball 505 is rotatably connected with the adjustment groove 503. When the mounting crank 1302 rotates, it will drive the locking ring 501 to rotate through the teeth. The locking ring 501 abuts against the locking plate 502, and the locking plate 502 approaches the lathe tool. The adjustment groove 503 on the locking plate 502 will continuously approach the lathe tool until the adjustment ball 505 abuts against the lathe tool. The adjustment ball 505 applies pressure to the adaptive elastic piece 504 until the adjustment groove 503 is completely attached to the lathe tool. The adjustment ball 505 can fully ensure the installation tightness of the lathe tool, and at the same time can also fully enable the lathe tool to be fully adjusted in attitude.

Teeth are respectively arranged on the deflection frame 701 and the deflection sub-frame 702. The first laser 8 and the second laser 9 are respectively arranged on the deflection frame 701 and the deflection sub-frame 702. Wire installation grooves are respectively arranged on the deflection frame 701 and the deflection sub-frame 702. The output ends of the first laser 8 and the second laser 9 face each other. During the scanning detection, the first laser 8 and the second laser 9 work to emit laser with a specific frequency. The deflection frame 701 and the deflection sub-frame 702 are responsible for adjusting the attitudes of the first laser 8 and the second laser 9. At the same time, the deflection frame 701 and the deflection sub-frame 702 can adopt an electric lifting structure to adapt to lathe tools with various heights.

[0030] The output end of the deflection motor 6 passes through the detection box 601 and is rotatably connected with the detection box 601. A transmission gear 602 and a reverse gear set 603 are arranged inside the detection box 601. A deflection gear 604 is arranged on the output end of the deflection motor 6. The deflection gear 604 meshes with the transmission gear 602 and the reverse gear set 603 respectively.

The deflection frame 701 and the deflection sub-frame 702 mesh with the transmission gear 602 and the reverse gear set 603 respectively. During the detection process, the deflection motor 6 drives the deflection gear 604 to rotate. The deflection gear 604 transmits the power to the transmission gear 602 and the reverse gear set 603, so that the deflection frame 701 and the deflection sub-frame 702 can change their attitudes, and the first laser 8 and the second laser 9 form a certain angle, which can locally detect the running lathe tool. It can be known that the deviation state of the tool running in different directions can be obtained, and the problem of missing tool detection during single detection can be avoided.

[0032] A liquid coating assembly 14 is provided in the tool mounting ring 4. The liquid coating assembly 14 includes a liquid coating ring 1401.

A plurality of liquid coating ports 1403 are provided on the inner ring of the liquid coating ring 1401. A dispersion brush 1404 is provided on each liquid coating port 1403. The dispersion brush 1404 is communicated with the liquid coating port 1403. During the detection process, for some minor defects, the data changes detected by the laser are relatively small. At this time, when manually capturing or positioning, it will cause problems that cannot be accurately repaired. By filling the outer surface of the lathe tool with glue or diffusion liquid, the angle change of laser refraction can be increased, and the original change data can be enlarged. Utilizing the different gravitational forces of the liquid at the defect and the different masses of the absorbed glue, relatively minor defects can be directly located, which provides sufficient convenience for subsequent maintenance personnel. At the same time, for the tool treated with glue coating, its anti-pollution degree will also be greatly weakened, reducing the detection error.

[0033] A plurality of equal-pressure ports 1405 are provided on the dispersion brush 1404. A resistance ball 1406 and a resistance elastic piece 1407 are respectively provided in each equal-pressure port 1405. The resistance ball 1406 is in sliding contact with the equal-pressure port 1405. The resistance ball 1406 is in sliding contact with the resistance elastic piece 1407. The caliber of the equal-pressure port 1405 is smaller than the diameter of the resistance ball 1406. During the coating process, the coating medium will be communicated with the externally installed supply box, so that the buffer cavity 1402 is filled with the coating medium and presses on the equal-pressure ports 1405. Until the pressure at each equal-pressure port 1405 is the same, the liquid at the equal-pressure port 1405 will simultaneously push open the resistance ball 1406, so that the coating medium is fully and evenly diffused on the lathe tool, ensuring the uniformity of the medium and avoiding the problem of glue accumulation.

[0034] The detection support 1 includes a support arm 101 and a mounting base 102. The support arm 101 is arranged on the mounting base 102. A lifting arm 103 is slidably connected to the support arm 101. Locking ports are respectively arranged on the lifting arm 103 and the support arm 101. A locking bolt 104 is arranged in the locking port. The tool holder 2 is slidably connected to the lifting arm 103. The body part of the detection motor 3 is fixedly connected to the lifting arm 103. By adjusting the distance between the lifting arm 103 and the support arm 101, the height of the detection support 1 is adjusted to adapt to lathe tools of various heights and also to various installation positions of the detection support. After the adjustment is completed, it is locked by the locking bolt 104. The locking bolt 104 connects to the locking port, so that the positions between the lifting arm 103 and the support arm 101 are determined relative to each other.

[0035] Working principle: Before detecting the tool, adjust the distance between the lifting arm 103 and the support arm 101 to adjust the height of the detection support 1 and adjust to a suitable current detection height to adapt to the lathe. Subsequently, install the lathe tool on the locking component 5, adjust and align the motor 13. The moving gear 1301 drives the tool holder 2 to move. It moves to the corresponding position. Subsequently, the tool holder 2 is sent into the locking component 5. Rotate the installation crank 1302. The installation crank 1302 adjusts the diameter of the locking component 5. Subsequently, the lathe tool will enter between the first laser 8 and the second laser 9. Subsequently, through the recorder 10 and the laser converter 11, the working states of the first laser 8 and the second laser 9 are controlled. The output ends of the first laser 8 and the second laser 9 face each other. When performing the scanning detection, the first laser 8 and the second laser 9 work to emit laser of a specific frequency. The deflection motor 6 drives the deflection gear 604 to rotate. The deflection gear 604 transmits the power to the transmission gear 602 and the reverse gear group 603, so that the deflection frame 701 and the deflection sub-frame 702 can change their postures, so that the first laser 8 and the second laser 9 form a certain angle, and the running lathe tool can be locally detected. By filling the surface of the lathe tool with glue or diffusion liquid, the angle change of laser refraction is increased, and the original change data can be enlarged. Due to the different gravitational forces of the liquid at the defect, the laser reflected back will be received by the signal receiver 12 and converted into an electrical signal and transmitted into the recorder 10. The recorder 10 will obtain the situation of laser reflection, so as to obtain the self-state of the tool. At the same time, by adjusting the position of the tool holder 2, the tool can be scanned in all directions to obtain more complete tool data.
