The probe 3 refers to the patent document with the patent application number CN2019215352872. The probe 3 is fixedly connected to the upper side of the probe seat 2, and the probe seat 2 is fixedly connected to the outer wall of the probe support 1. The rod loading detection device can achieve a measurement accuracy of 1μm. Through the fixed connection between the probe support 1, the probe seat 2, the probe 3 and the measuring needle block 4, the structure of the device is simplified, the overall rigidity is enhanced, and the stability of the cooperative work of each component in the detection process is ensured, thereby improving the detection accuracy and reliability.

The loading detection device is fixed to the inside of the lathe, the lower side of the connecting part 11 end face as a support point, that is, the loading detection device is fixed only by the connecting part 11, the rest of the parts are connected with the ring mouth part 13 on the same end face perpendicular to the ground, in a suspended state. The turning angle of connecting part 11 and extension part 12, the turning angle of extension part 12 and ring mouth part 13 can effectively disperse the gravity and external force borne by connecting part 11, the extension part 12 away from the side of the connecting part 11 integral ring mouth part 13, the ring mouth part 13 middle part is provided with through hole, that is, through hole, its ring mouth part 13 middle part through hole connection thread connection probe seat 2. The integral connecting part 11, extension part 12 and ring mouth part 13 eliminate the risk of loose of traditional welding or bolt connection, make the connection of probe support 1 and probe seat 2 more firm, at the same time, reduce the cost of processing and assembly.
[0060] In order to facilitate the fixation of the probe seat 2 and the probe support 1, the ring mouth part 13 includes: upper ring 131 and lower ring 132, which divides the through hole in the middle of the ring mouth part 13 into two parts, wherein the upper ring 131 protrudes inward, and the inner thread is provided in the inner wall of the lower ring 132. The probe seat 2 is stepped, and the outer stepped protrusion of the probe seat 2 is divided into upper and lower parts, wherein the upper side of the upper part of the stepped protrusion is an end face for bearing, and when the probe seat 2 is installed to the ring mouth part 13, the bearing surface is attached to the lower side of the inward protrusion of the upper ring 131 of the ring mouth part 13. The outer thread is provided on the outer part of the lower part of the stepped protrusion, and the outer thread and the inner thread are connected. During installation, first pass the through hole of the ring mouth part 13 from the lower end of the ring mouth part 13, that is, the end face close to the side of the connecting part 11, at this time, the upper side of the outer stepped protrusion of the probe seat 2 is attached to the lower side of the inward protrusion of the upper ring 131 of the ring mouth part 13. Limit the movement of the probe seat 2, so that the probe seat 2 cannot continue to pass through the through hole, at this time, rotate along the axial direction of the probe seat 2, the rotation direction is the fastening direction of the outer thread and the inner thread, the outer thread and the inner thread are connected, so that the probe seat 2 and the ring mouth part 13 are fixedly connected. Through the limiting action of the upper ring and the cooperation of the inner and outer threads, the adjustable fastening of the probe seat 2 and the probe support 1 is realized, which is convenient for installation and removal, and can effectively prevent the loosening of the threads caused by vibration, and ensure the stability of the connection in long-term use.
[0061] In order to ensure the connection of the bar feeding detection device and the lathe body 01, a through hole 5 is provided in the through connecting part 11, and by adjusting the distance position of the connecting seat of the lathe body 01, the size of the mounting hole realizes the adjustable installation position of the feeding detection device with different sizes, and the connecting part passes through the through hole 5 and is connected with the lathe body 01. The cooperation design of the through hole and the connecting part makes the detection device can be quickly and flexibly fixed on the lathe body 01, reduces the installation and debugging time, at the same time ensures the rigid connection of the detection device and the lathe, avoids the displacement error in the processing process.
[0062] According to Figures 4-8 As shown in the figure, the numerical control lathe comprises: a lathe body 01, a feeding device 02 is arranged on the feeding side 011 of the lathe body 01, and the feeding device 02 conveys the bar. The discharge side 012 of the lathe body 01 is fixedly connected with a bar feeding detection device. When the bar to be processed is sent into the lathe body 01 by the feeding device 02, the bar contacts the probe block 4, the probe 3 sends a signal, the numerical control lathe receives the probe signal, the PLC executes the clamp clamping command, and at this time the feeding is completed. Then start the next processing, if the bar feeding is not in place, the probe 3 will not trigger, and the machine tool will not execute the processing program. The probe block 4 of the bar feeding detection device located on the discharge side 012 can detect the passing of the bar. The bar feeding detection device is arranged in the feeding side 011 of the lathe body 01, and is used in combination with the feeding side 011, which realizes the synchronous processing and detection, reduces the error in the processing process, reduces the labor demand, optimizes the overall layout of the lathe, and improves the automation level and production efficiency.
[0063] In order to optimize the feeding device 02 and improve the conveying efficiency, the feeding device 02 is a gravity feeding device. The gravity feeding device is used instead of the traditional power driven feeding mechanism, and the material flows uniformly under the action of gravity, which can realize continuous and stable feeding. Simplify the structure design, reduce the energy consumption and maintenance cost, at the same time, utilize the stable and continuous bar conveying by the gravity potential energy.
[0064] In order to ensure the stable operation of the gravity feeding device, the gravity feeding device comprises a first support 021, a second support 022 and a third support 023. The first support 021, the second support 022 and the third support 023 are parallel to each other, so as to support the straight movement of the bar. The upper side of the first support 021 is fixedly connected with a support rod, and the upper side of the support rod is fixedly connected with a first roller 031. Correspondingly, the upper side of the third support 023 is fixedly connected with a support rod, and the support rod is fixedly connected with a second roller 032. The upper side of the second support 022 supports the bar to be processed. The gravity feeding device further comprises a gravity block 024, a dragging steel wire 025, a guide groove 026 and a pushing piece 027. One end of the dragging steel wire 025 is fixedly connected with the gravity block 024 by passing through the first roller 031. Different gravity blocks can be flexibly configured according to the size of the thrust demand. The other end of the dragging steel wire 025 is fixedly connected with the pushing piece 027 by passing through the second roller 032. The pushing piece 027 is arranged in the guide groove 026 at the tail end of the bar to be processed. The guide groove 026 is fixedly connected to the first support 022 and has a groove passing through both ends. The through direction of the groove is the same as the axial direction of the pushing piece 027. The pushing piece 027 is installed from the end of the groove away from the lathe body 01 into the guide groove 026. Through the cooperation of the gravity block, the dragging steel wire and the pushing piece, the gravitational potential energy is converted into the pushing force on the bar, realizing the automatic feeding function without external energy, and the pushing direction is consistent with the axis of the bar, avoiding feeding deviation.
[0065] In order to ensure the force transmission of the gravity feeding device, the gravity feeding device further comprises a third roller 033, a fourth roller 034 and a fifth roller 035. One end of the dragging steel wire 025 is fixedly connected with the gravity block 024, and then passes through the first roller 031. The fourth roller 034 and the first roller 031 are coaxially arranged and located at the upper end of the support rod of the first support 021. The upper end of the support rod is fixedly connected with a connecting piece. The fourth roller 034 and the first roller 031 are fixedly connected on both sides of the connecting piece. In order to ensure that the dragging steel wire 025 can pass through the fourth roller 034 from the first roller 031, the third roller 033 is fixedly connected below the first roller 031. In this way, after the dragging steel wire 025 passes through the first roller 031 and changes the angle, it passes through the third roller 031 below and changes the angle again to pass through the fourth roller 034 above. The third roller 033 is equivalent to being arranged below the first roller 031 and the fourth roller 034 close to the center. It plays a role in adjusting the angle of the dragging steel wire 025, so that the dragging steel wire 025 can be connected from the first roller 031 to the fourth roller 032, thereby ensuring the smooth transmission of gravity.
[0066] In order to optimize the transmission efficiency of force, the fifth roller 035 and the third roller 033 are coaxially arranged. After the pulling wire 025 passes around the fourth roller 034, it continues to pass around the fifth roller 035 located on the lower side of the fourth roller 034, then passes around the second roller 032 located on the upper side of the third support 023, and finally is fixedly connected to the pushing member 027. By adding the third roller, the fourth roller and the fifth roller, the winding path of the pulling wire is optimized, forming a multi-stage pulley block. This design changes the direction of force transmission and increases the effective contact points, significantly reducing the frictional resistance between the wire and the roller, so that the gravitational potential energy of the gravity block 024 is more efficiently converted into the linear traction force of the pushing member 027. At the same time, the coaxial arrangement of the rollers ensures the synchronization and stability of the wire during movement, avoiding energy loss or jamming problems caused by wire deviation, thereby improving the reliability and continuity of the overall transmission of the gravity feeding device. In addition, by distributing the positions of the rollers, there is a certain transverse distance between the end of the pulling wire 025 connected to the gravity block 024 and the end of the pulling wire 025 fixed to the pushing member 027. This avoids the overlapping of the pulling wire 025 between the rollers when the gravity block 024 falls, which can cause the gravity block 024 to touch the processed bar during falling, causing interference problems.
[0067] In order to ensure that the processed bar can pass through the slot of the support groove 03 and enter the lathe body 01 from the feeding side 011 when it is transmitted by the feeding device 02, the first support 021, the second support 022 and the third support 023 are fixedly connected with the support groove 03 at the upper end, and the support groove 03 supports the processed bar. By arranging multiple support grooves 03 on the support, the symmetrical arrangement of the support grooves 03 provides multiple-point uniform support for the processed bar, preventing the bar from sagging or deviating due to its own weight during transportation, and ensuring smooth movement along the predetermined path.
[0068] In order to make the gravity of the gravity block 024 pass through the plurality of rollers to be converted into the pushing force to the bar to be processed. A pushing member 027 is further arranged, which comprises a pushing rod 0271, a pushing head 0272 and a pulling head 0273, and the pushing rod 0271, the pushing head 0272 and the pulling head 0273 are integrally formed. The pushing rod 0271 is cylindrical, and the diameter thereof is greater than the diameter of the bar to be processed. The pushing head 0272 and the pulling head 0273 are respectively located at two ends of the pushing rod 0271, and the end face of the pushing head 0272 abuts against the end face of the tail end of the bar to be processed. The pulling head 0273 is fixedly connected with one end of the dragging wire 025. The connection mode of the dragging wire 025 and the pulling head 0273 comprises that a hole is formed on the pulling head 0273, and the end of the dragging wire 025 close to the pulling head 0273 is fixedly connected with the hole on the pulling head 0273 in a threaded connection mode or a rivet connection mode. When the gravity block 024 moves vertically downward to the ground, the dragging wire 025 is driven, the dragging wire 025 is tensioned through the change of the force transmission direction between the rollers, so as to ensure that it can bear the corresponding load, and the pulling head 0272 is pulled to move linearly to the discharging side 012, so that the pushing head 0272 pushes the bar to be processed into the lathe to be processed. After the bar to be processed is processed, the gravity block 024 is reset, the bar to be processed is added in the supporting groove 03, and the processing can be restarted. The pushing member 027 adopts the integrally formed design of the pushing rod 0271, the pushing head 0272 and the pulling head 0273, so as to ensure the accuracy and consistency of the pushing action. The end face of the pushing head 0272 directly abuts against the end face of the tail end of the bar to be processed, and through the rigid transmission of the integral structure, the pulling force of the dragging wire 025 can be efficiently converted into the linear pushing force to the bar, so as to avoid the feeding deviation caused by the deformation or displacement of the components. In addition, the fixed connection of the pulling head and the dragging wire enhances the tensile strength through the integral structure, reduces the risk of fatigue fracture in long-term use, and thus guarantees the durability and stability of the feeding device 02.
[0069] The above merely describes the preferred embodiments of the present application, and is not used to limit the protection scope of the present application.
