Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically to a measuring device for turning workpieces. Background Technology

[0002] Existing lathes, including conventional lathes and CNC lathes, all require measuring the workpiece dimensions before machining. The feed rate of the cutting tool is then calculated and the machine is stopped. The workpiece dimensions are measured again to ensure they meet the drawing requirements. The feed rate is then manually calculated again, and the cutting tool is fed in again. This process is repeated multiple times to achieve the dimensional requirements of the drawing. In this process, the accuracy of the measuring device is crucial for workpiece machining. However, during actual measurement, thin flakes are generated during the machining process. These flakes are curved or curled and adhere to the bottom of the workpiece, causing errors in the data measured by the measuring device. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a measuring device for turning workpieces, which effectively cleans the thin flaky debris attached to the workpiece and prevents the measuring device from measuring data errors due to the thin flaky debris adhering to the bottom of the workpiece.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A workpiece measuring device for turning includes a bracket on which a laser measuring device is fixed, and a cleaning device is also fixed on the bracket. The cleaning device includes a housing, inside which a central shaft is installed. One end of the central shaft is rotatably connected to the bottom end of the housing, and the other end extends out of the housing and is rotatably connected to the top end of the housing. An impeller is installed on the central shaft inside the housing. A turntable is fixed to the top end of the central shaft. A first cavity is provided in the middle of the turntable. Multiple air nozzles are provided on the top of the turntable. A second cavity communicating with the first cavity is provided on the top of the central shaft. An air inlet communicating with the second cavity is provided on the central shaft. The air inlet is located inside the housing. An air port communicating with the interior of the housing is provided on the housing.

[0006] Furthermore, the air inlet is located above the impeller, and the air port is located below the impeller.

[0007] Furthermore, the diameters of the top and bottom of the central shaft are larger than the diameter of the middle portion of the central shaft.

[0008] Furthermore, it also includes a tray, on which a screw is provided, the screw passing through the tray, one end of the screw being rotatably connected to the bracket, and the other end being equipped with a handwheel.

[0009] Furthermore, the laser measuring device is a laser probe, a laser rangefinder, or a laser measuring instrument.

[0010] Beneficial effects

[0011] 1. This utility model provides a workpiece measuring device for turning. The bracket is installed on the lathe, so that the cleaning device is closer to the workpiece than the laser measuring device. During the workpiece machining process, high-pressure gas is introduced into the air inlet, causing the gas to drive the impeller to rotate. While driving the impeller to rotate, the gas enters the second cavity through the air inlet and then enters the first cavity, and finally exits through the jet hole. When the gas is discharged, the impeller drives the central shaft to rotate, which in turn drives the turntable to rotate. As a result, the gas is ejected and rotates upward. When it comes into contact with the workpiece surface, it has both impact force and centrifugal force generated by rotation, thus cleaning the workpiece surface. This can effectively remove the thin flakes attached to the workpiece and prevent the measuring device from measuring data errors due to the thin flakes attached to the bottom of the workpiece.

[0012] 2. The present invention provides a workpiece measuring device for turning, which is equipped with a support plate that can be fixed on the lathe during installation. The support plate is provided with a screw that passes through the support plate. One end of the screw is rotatably connected to the bracket, and the other end is equipped with a handwheel. This structure drives the screw to move back and forth on the support plate by turning the handwheel, thereby driving the bracket to move back and forth, which facilitates the adjustment of the position of the laser detection device.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example 1:

[0024] This embodiment provides a measuring device for turning workpieces, such as... Figures 1 to 2 As shown, the device includes a support 2, on which a laser measuring device 1 and a cleaning device 8 are fixed. The laser measuring device 1 can use existing devices such as laser probes, laser rangefinders, or laser measuring instruments; its measuring principle is well known to those skilled in the art and will not be elaborated here. The cleaning device 8 includes a housing 8-1, inside which a central shaft 8-2 is installed. One end of the central shaft 8-2 is rotatably connected to the bottom end of the housing 8-1, and the other end extends out of the housing 8-1 and is rotatably connected to the top end of the housing 8-1. An impeller 8-3 is installed on the central shaft 8-2 inside the housing 8-1. A turntable 8-4 is fixed to the top end of the central shaft 8-2, and a first cavity 8-41 is provided in the middle of the turntable 8-4. The top of the turntable 8-4 is provided with multiple jet ports 8-42, and the top of the central shaft 8-2 is provided with a second cavity 8-21 communicating with the first cavity 8-41. The central shaft 8-2 is provided with an air inlet 8-22 communicating with the second cavity 8-21. The air inlet 8-22 is located inside the outer shell 8-1. The outer shell 8-1 is provided with an air inlet 8-11 communicating with the interior of the outer shell 8-1. In this embodiment, the air inlet 8-22 is located above the impeller 8-3, and the air inlet 8-11 is located below the impeller 8-3. As a variation, the air inlet 8-22 can also be located below the impeller 8-3, and the air inlet 8-11 can be located above the impeller 8-3.

[0025] The aforementioned workpiece measuring device is installed on a lathe. During installation, the bracket 2 is mounted on the lathe, so that the cleaning device 8 is closer to the workpiece 7 than the laser measuring device 1. During the workpiece machining process, high-pressure gas is supplied to the air inlet 8-11, causing the gas to drive the impeller 8-3 to rotate. While driving the impeller 8-3 to rotate, the gas enters the second cavity 8-21 through the air inlet 8-22 and then enters the first cavity 8-41, finally exiting through the jet nozzle 8-42. When the gas is discharged, the impeller 8-3 drives the central shaft 8-2 to rotate, which in turn drives the turntable 8-4 to rotate. This causes the gas to rotate and move upward after being ejected. When it comes into contact with the workpiece surface, it has both impact force and centrifugal force generated by rotation, cleaning the workpiece surface. This effectively removes the thin flakes attached to the workpiece, preventing the measuring device from measuring data errors due to the thin flakes adhering to the bottom of the workpiece.

[0026] In actual manufacturing, the diameter of the top of the central shaft 8-2 is preferably larger than the diameter of the middle part of the central shaft, so as to facilitate the setting of the second cavity 8-21. Correspondingly, the diameter of the bottom of the central shaft 8-2 is preferably larger than the diameter of the middle part of the central shaft 8-2.

[0027] In actual manufacturing, a support plate 4 can also be set. During installation, the support plate 4 can be fixed on a lathe. A screw 3 is provided on the support plate, which passes through the support plate 4. One end of the screw 3 is rotatably connected to the bracket 2, and the other end is equipped with a handwheel 5. This structure drives the screw 3 to move the support plate 4 first by turning the handwheel 5, thereby driving the bracket 2 to move back and forth, which facilitates the adjustment of the position of the laser measuring device 1.

[0028] Example 2:

[0029] Unlike the embodiments described above, this embodiment also includes an induced draft device installed on the lathe. See [link to relevant documentation]. Figure 3 In this embodiment, the air-exhaust device includes an air-exhaust duct 9-1, a filter screen 9-2 and a fan 9-3 installed inside the air-exhaust duct 9-1. The filter screen 9-2 is positioned relative to the fan 9-3 near the air inlet of the air-exhaust duct 9-1. A chip discharge port 9-4 is provided on the bottom surface of the air-exhaust duct 9-1 near the filter screen 9-2. The chip discharge port 9-4 is located on the side of the filter screen 9-2 near the air inlet of the air-exhaust duct 9-1. This structure mainly attracts the debris cleaned by the cleaning device 8 into the air-exhaust duct 9-1 through the action of wind suction. After being blocked by the filter screen 9-2, a negative pressure suction effect is generated at both the chip discharge port 9-4 and the air inlet of the air-exhaust duct 9-1 during use, attracting the debris. After use, the debris attached to the filter screen 9-2 can be cleaned through the chip discharge port 9-4. The air-exhaust device can also be fixed on the bracket 2. The air inlet of the air-exhaust duct 9-1 is preferably set slightly higher than the height of the cutting tool 6.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
