[0024] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0025] The utility model provides a shockproof detection mechanism suitable for bar processing, comprising:

[0026] The oil cylinder limit support is connected to the oil cylinder rear cover, and the oil cylinder limit support is provided with at least two workpiece limit pins in the radial direction, and the workpiece limit pins extend into the inner hole of the oil cylinder limit support;

[0027] The limit detection outer ring is connected to the pull rod;

[0028] The detection switch is arranged on the outer peripheral shell of the oil cylinder, and the detection switch is connected to the limit detection outer ring signal.

[0029] Specifically, during the bar loading process of the existing lathe, the bar needs to be inserted and installed from the rear of the cylinder, and then the outer periphery of the bar is clamped and fixed by the pull rod, so that the bar can be processed. According to the above steps, the shockproof detection mechanism is arranged at the rear of the lathe cylinder, and the cylinder limit support is installed on the rear cover of the cylinder. The center of the cylinder limit support is provided with an inner hole for the bar to pass through during loading and installation. When the feeding length of the bar meets the requirements, the outer periphery of the bar can be clamped and fixed by the radially arranged workpiece limit pin, and then the pull rod is moved to clamp the bar. During the movement of the pull rod, the limit detection outer ring on the pull rod also moves accordingly. In this way, the detection switch can judge whether the pull rod is in a clamped state or a loose state with respect to the bar according to the position where the limit detection outer ring stops, thereby performing corresponding operations on the bar.

[0030] Optionally, the oil cylinder limit support is arranged in the water collecting box, and there is an operating space between the outer side of the oil cylinder limit support and the inner side of the water collecting box.

[0031] Specifically, the size of the cylinder limit support is designed according to the internal space of the water collecting box, so that the original lathe structure does not need to be destroyed when the shockproof detection mechanism is installed. In addition, a certain space is reserved between the outer surface of the cylinder limit support and the side wall of the water collecting box to facilitate the entry of tools when adjusting the workpiece limit pin.

[0032] Optionally, the inner hole of the oil cylinder limit support is used to pass the bar, and the workpiece limit pin is threadedly connected to the oil cylinder limit support.

[0033] Optionally, the oil cylinder limit support is connected to the oil cylinder rear cover through a long screw.

[0034] Specifically, a long screw is used to connect the cylinder limit support and the cylinder rear cover, so as to ensure that the cylinder and the cylinder limit support rotate synchronously, and the cylinder limit support is annular in structure, and the cylinder limit support and the cylindrical structure of the cylinder are centered along the same axis. In this way, when the rod enters the cylinder limit support for fixation, the workpiece limit pin can be screwed into the inner hole in the center along the radial direction, so that the rod can be fixed in the center. When the rod needs to continue to be fed into the lathe, the workpiece limit pin can be screwed out in the radial direction and pushed out from the inner hole in the center, and the rod will no longer be clamped and fixed by the workpiece limit pin.

[0035] Optionally, a pull rod contact ring is provided at the end of the pull rod, and the outer periphery of the limit detection outer ring is connected to the pull rod contact ring.

[0036] Optionally, the side wall of the pull rod contact ring is connected to the pull rod by a fastening screw.

[0037] Specifically, the end of the pull rod is connected to the limit detection outer ring through the pull rod contact ring, the pull rod contact ring is connected to the end of the pull rod close to the rear cover of the cylinder, the pull rod contact ring is set at the outer end of the pull rod, and is connected to the pull rod through the side wall of the pull rod contact ring. The two are fixed with fastening screws so that they slide synchronously, which can drive the limit detection outer ring to move, thereby detecting the fixing state of the pull rod on the rod through the detection switch.

[0038] Optionally, the detection switch includes a clamping sensing probe and a loosening sensing probe, and the limit detection outer ring is movably arranged between the clamping sensing probe and the loosening sensing probe.

[0039] Specifically, the detection switch can judge the fixed state of the pull rod and the bar material by the moving direction of the limit detection outer ring, and can also judge the fixed state of the pull rod and the bar material by the stop position of the limit detection outer ring. Two probes are set in the detection switch, the loosening sensing probe is set at one end close to the rear cover of the oil cylinder, and the clamping sensing probe is set at the end away from the rear cover of the oil cylinder. When the bar material is fed into place, the pull rod moves in the direction close to the rear cover of the oil cylinder. When the pull rod clamps and fixes the bar material, the limit detection outer ring moves to the detection range of the clamping sensing probe, and the stay time of the limit detection outer ring exceeds the preset time, so that the lathe starts to lathe the bar material; when the bar material continues to be fed, the pull rod moves in the direction away from the rear cover of the oil cylinder. When the pull rod completely separates and opens the bar material, the limit detection outer ring moves to the detection range of the loosening sensing probe, and the stay time of the limit detection outer ring exceeds the preset time, so that the feeding mechanism starts to continue to feed the bar material to the lathe. The detection switch can accurately detect the clamping state of the bar material, which is convenient for feeding and processing the bar material. There is no need to segment the bar material in advance, thus avoiding the waste of raw materials.

[0040] Optionally, the oil cylinder limit support and the oil cylinder rear cover are detachably connected.

[0041] Specifically, the lathe can process bars of varying sizes. When the bar diameter exceeds the inner diameter of the cylinder limit support, the support must be replaced. Because the cylinder limit support and the tie rod status detection mechanism of the anti-vibration detection mechanism are located on the cylinder rear cover and tie rod, respectively, simply replacing the cylinder limit support allows for processing larger bars, making the entire operation simple and quick.

[0042] Optionally, two workpiece limiting pins are provided, and a line connecting the two workpiece limiting pins passes through the center of the cylinder limiting support.

[0043] Specifically, two workpiece limit pins are set on the oil cylinder limit support, and the two workpiece limit pins are symmetrically arranged with the center of the oil cylinder limit support. When the bar needs to be processed, the two workpiece limit pins can be used to fit the two sides of the bar to clamp and fix the bar, so that the force on the bar is stable, and the vibration problem of the bar at the cylinder end during lathe processing is solved.

[0044] The utility model also provides a horizontal CNC lathe, comprising the above-mentioned anti-vibration detection mechanism suitable for bar processing.

[0045] Specifically, the shockproof detection mechanism is installed on the lathe, and the modification cost is low. The clamping state of the bar material can be detected according to the position of the limit detection outer ring, and the judgment is more accurate. In this way, the shockproof and in-place detection of bar material workpieces at the lathe cylinder end can be realized, which helps to improve the processing efficiency and accuracy of bar material workpieces.

When the rod is stretched When the input length meets the processing requirements, the cylinder piston rod moves backward and drives the claw to clamp the workpiece. At this time, the limit detection outer ring 4 connected to the piston rod moves into place, and the clamping induction probe 7 transmits a signal after detection, so that the system confirms that the workpiece is in place and can start processing.
