Description

Technical Field

[0001] The utility model relates to the technical field of workpiece calibration and detection, in particular to a workpiece calibration and detection device for a numerical control lathe. Background Technique

[0002] A numerical control lathe usually processes a rotating workpiece with a tool. It has high efficiency and is widely used in the fields of mechanical manufacturing and repair. Most of the processed workpieces are cylindrical or disc-shaped workpieces. Before processing the workpiece, workers need to fix the workpiece, and after fixing, they need to calibrate the workpiece. Currently, the method of calibrating the workpiece is usually to detect the side surface of the workpiece through a calibration table.

[0003] After retrieval: A workpiece calibration and detection device for a numerical control lathe with the patent number CN219379000U belongs to the technical field of workpiece calibration and detection, including a processing table. A moving support plate and a fixed support plate are arranged on the upper surface of the processing table. The fixed support plate is located on one side of the moving support plate. A clamping member is rotatably installed inside the moving support plate. A top rod is fixedly connected to the side surface of the fixed support plate corresponding to the clamping member. A fixed disk is arranged on one side of the top rod. A sliding plate is slidably arranged inside the fixed disk. A cross plate is arranged at one end of the sliding plate. A strip-shaped through hole is opened inside the cross plate. A second measuring rod is arranged in the strip-shaped through hole in an array. Millimeter-scale graduation lines are marked on the side surface of the second measuring rod. A head detection component is arranged on one side surface of the fixed disk.

[0004] However, the above-mentioned workpiece calibration and detection device for a numerical control lathe still has deficiencies. The method of using the naked eye of a person to observe the movement of the measuring rod to detect the calibration situation of the workpiece is not easy to see clearly with the naked eye of a person because the displacement of the measuring rod is small, which makes the calibration and detection of the workpiece inconvenient. And using a screw to disassemble, install and fix the rotating disk is not conducive to quick disassembly and replacement. Therefore, we propose a workpiece calibration and detection device for a numerical control lathe to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned drawbacks and propose a workpiece calibration and detection device for a numerical control lathe.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A workpiece calibration and detection device for a numerically controlled lathe, comprising a lathe table and an adjustment plate. A support plate is fixedly connected to the top of the lathe table. A drive motor is fixedly connected to one side of the support plate. A three-jaw chuck is fixedly connected to the output shaft of the drive motor. An adjustment assembly is provided between the lathe table and the adjustment plate. A workpiece calibration and detection mechanism is provided on the adjustment plate. The workpiece calibration and detection mechanism includes a cross bar, a mounting sleeve and a detection disc. The cross bar is fixedly installed on one side of the adjustment plate. The detection disc is fixedly installed on one side of the mounting sleeve. A quick disassembly and assembly component is provided between the mounting sleeve and the cross bar. A workpiece calibration and detection component is provided on the detection disc.

[0008] Preferably, the workpiece calibration and detection component includes a chute opened on one side of the detection disc, a display screen fixedly connected to one side of the detection disc, and a displacement sensor fixedly connected to the top of the detection disc. A slider is slidably sleeved in the chute. A measuring rod is fixedly connected to one side of the slider. A connecting rod is fixedly connected to the top of the slider. The top end of the connecting rod is fixedly connected to a cross plate, and the cross plate cooperates with the displacement sensor.

[0009] Preferably, a sliding hole is opened on the top of the detection disc, and the connecting rod is slidably sleeved in the sliding hole.

[0010] Preferably, the quick disassembly and assembly component includes two limiting plates and two cylinders. The two limiting plates are respectively fixedly connected to the top and bottom of the cross bar. A clamping groove is fixedly connected to one side of each of the two limiting plates away from each other. The two cylinders are respectively fixedly connected to the top and bottom of the mounting sleeve. A return spring is fixedly connected to the inner wall of the cylinder. One end of each of the two return springs away from each other is fixedly connected to a lifting plate. A clamping plate is fixedly connected to the inner side of each of the two lifting plates. The two clamping plates are respectively movably clamped in the corresponding clamping grooves. The mounting sleeve is slidably sleeved on the outside of the cross bar. A ball rod is fixedly connected to the outside of each of the two lifting plates.

[0011] Preferably, the two return springs are respectively sleeved on the outside of the corresponding ball rods.

[0012] Preferably, two limiting grooves are opened on one side of the mounting sleeve, and the two limiting plates are respectively slidably sleeved in the corresponding limiting grooves.

[0013] Preferably, the adjustment assembly includes a groove opened on the top of the lathe table. The same threaded rod is rotatably connected to the inner walls of both sides of the groove. A drive plate is threadedly sleeved on the outside of the threaded rod. The adjustment plate is fixedly connected to the top of the drive plate.

[0014] Preferably, a hand wheel is fixedly connected to one end of the threaded rod, and the drive plate is slidably sleeved in the groove.

[0015] In this utility model, for the described numerical control lathe workpiece calibration and detection device, the workpiece to be machined is clamped and fixed by a three-jaw chuck. When the driving motor is started, the driving motor drives the rotation of the three-jaw chuck and the workpiece. If the measuring rod, slider, connecting rod, and cross plate move, it indicates that the workpiece calibration is unqualified and the workpiece needs to be recalibrated and fixed. Through the displacement sensor, the movement of the cross plate can be measured, and the data measured by the displacement sensor is displayed on the display screen. Personnel can, based on the data on the display screen, more clearly and intuitively detect the workpiece calibration situation, resulting in better use effects. On the contrary, during the rotation process, if the value of the displacement sensor does not change, it indicates that the measuring rod does not move, further indicating that the workpiece calibration is good;

[0016] In this utility model, for the described numerical control lathe workpiece calibration and detection device, when pulling out two ball rods outward, the two ball rods drive the two lifting plates and the clamping plate to move away from each other and disengage from the card slot, thus not fixing the limiting plate and the mounting sleeve. The mounting sleeve and the detection disk can be disassembled from the cross bar, and then the workpiece can be machined. At the same time, it is convenient for maintenance and replacement. When detection is required, due to the guiding and limiting of the limiting plate and the limiting slot, the mounting sleeve can be positioned and sleeved on the outside of the cross bar. When pushing the mounting sleeve to the right, the clamping plate is automatically pressed and compresses the return spring. When it is completely sleeved, at this time, the clamping plate is aligned with the card slot, and under the elastic force of the return spring, the two clamping plates move closer to each other and are clamped in the card slot, so that the detection disk can be installed on the cross bar for detecting the workpiece calibration;

[0017] The structure of this utility model is reasonably designed. Through the settings of the displacement sensor, connecting rod, slider, measuring rod, cross plate, and display screen, and by displaying the data measured by the displacement sensor on the display screen, the workpiece calibration situation can be seen more clearly and intuitively, resulting in better use effects. At the same time, it is conducive to quickly and efficiently disassembling and assembling the detection disk for replacing the mounting sleeve and the detection disk, which is convenient for use.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Referring to Figures 1-5 , a workpiece calibration and detection device for a numerically controlled lathe includes a lathe table 1 and an adjustment plate 4. A support plate 16 is fixedly connected to the top of the lathe table 1. A drive motor 17 is fixedly connected to one side of the support plate 16. A three-jaw chuck 18 is fixedly connected to the output shaft of the drive motor 17. An adjustment assembly is provided between the lathe table 1 and the adjustment plate 4. A workpiece calibration and detection mechanism is provided on the adjustment plate 4. The workpiece calibration and detection mechanism includes a cross bar 7, a mounting sleeve 8 and a detection disc 6. The cross bar 7 is fixedly installed on one side of the adjustment plate 4. The detection disc 6 is fixedly installed on one side of the mounting sleeve 8. A quick disassembly and assembly component is provided between the mounting sleeve 8 and the cross bar 7. A workpiece calibration and detection component is provided on the detection disc 6.

[0026] In the present utility model, the workpiece calibration and detection assembly includes a sliding groove 19 formed on one side of the detection disc 6, a display screen 11 fixedly connected to one side of the detection disc 6, and a displacement sensor 12 fixedly connected to the top of the detection disc 6. A slider 20 is slidably sleeved in the sliding groove 19. One side of the slider 20 is fixedly connected to a measuring rod 15. The top of the slider 20 is fixedly connected to a connecting rod 14. The top end of the connecting rod 14 is fixedly connected to a cross plate 13. The cross plate 13 cooperates with the displacement sensor 12. When the driving motor 17 is started, the driving motor 17 drives the rotation of the three-jaw chuck 18 and the workpiece. If the measuring rod 15, the slider 20, the connecting rod 14, and the cross plate 13 move, it indicates that the workpiece calibration is unqualified and the workpiece needs to be recalibrated and fixed. Through the displacement sensor 12, the movement of the cross plate 13 can be measured, and the data measured by the displacement sensor 12 is displayed on the display screen 11. Personnel can, through the data on the display screen 11, more clearly and intuitively detect the workpiece calibration situation, making the use effect better. On the contrary, during the rotation process, if the value of the displacement sensor 12 does not change, it indicates that the measuring rod 15 does not move, and further indicates that the workpiece calibration is good.

[0027] In the present utility model, a sliding hole is formed in the top of the detection disc 6, and the connecting rod 14 is slidably sleeved in the sliding hole, which facilitates guiding the connecting rod 14 and makes its movement more stable.

[0028] In the present utility model, the quick disassembly and assembly component includes two limiting plates 9 and two cylinders 10. The two limiting plates 9 are respectively fixedly connected to the top and bottom of the cross bar 7. On the mutually remote sides of the two limiting plates 9, clamping grooves 21 are respectively fixedly connected. The two cylinders 10 are respectively fixedly connected to the top and bottom of the mounting sleeve 8. A return spring 24 is fixedly connected to the inner wall of the cylinder 10. At the mutually remote ends of the two return springs 24, lifting plates 23 are respectively fixedly connected. On the inner sides of the two lifting plates 23, clamping plates 22 are respectively fixedly connected. The two clamping plates 22 are respectively movably clamped in the corresponding clamping grooves 21. The mounting sleeve 8 is slidably sleeved on the outside of the cross bar 7. On the outer sides of the two lifting plates 23, ball rods 25 are respectively fixedly connected. When disassembly is required, the two ball rods 25 are pulled outwards. The two ball rods 25 drive the two lifting plates 23 and the clamping plates 22 to move away from each other and disengage from the clamping grooves 21, thus no longer fixing the limiting plate 9 and the mounting sleeve 8. The mounting sleeve 8 and the detection disc 6 are disassembled from the cross bar 7, and then the workpiece can be processed, and at the same time, it is convenient for maintenance and replacement. When detection is required, due to the guiding and limiting of the limiting plate 9 and the limiting groove 26, the mounting sleeve 8 can be positioned and sleeved on the outside of the cross bar 7. When the mounting sleeve 8 is pushed to the right, at this time, the clamping plate 22 is automatically pressed and compresses the return spring 24. When it is completely sleeved, at this time, the clamping plate 22 is aligned with the clamping groove 21. Under the elastic force of the return spring 24, the two clamping plates 22 approach each other and are clamped in the clamping groove 21, thereby the detection disc 6 can be installed on the cross bar 7 for detecting the workpiece calibration.

[0029] In the present utility model, two reset springs 24 are respectively sleeved on the outer sides of the corresponding cue sticks 25, which facilitates guiding the reset springs 24 and makes their movement more stable.

[0030] In the present utility model, two limiting grooves 26 are formed on one side of the mounting sleeve 8, and two limiting plates 9 are respectively slidably sleeved in the corresponding limiting grooves 26. Through the arrangement of the limiting grooves 26 and the limiting plates 9, the mounting sleeve 8 can be positioned and installed, and then the measuring rod 15, the connecting rod 14, and the displacement sensor 12 can be installed on the top of the detection disc 6.

[0031] In the present utility model, the adjusting assembly includes a groove 2 formed on the top of the lathe table 1. The same threaded rod 5 is rotatably connected to the inner walls on both sides of the groove 2. A driving plate 3 is threadedly sleeved on the outer side of the threaded rod 5, and an adjusting plate 4 is fixedly connected to the top of the driving plate 3. According to the length of the workpiece, the threaded rod 5 is rotated, and the threaded rod 5 drives the driving plate 3, the adjusting plate, and the detection disc 6 to move horizontally, so as to adjust the detection between the detection disc 6 and the three-jaw chuck 18, so as to calibrate and detect workpieces of different lengths.

[0032] In the present utility model, one end of the threaded rod 5 is fixedly connected with a handwheel, and the driving plate 3 is slidably sleeved in the groove 2, which facilitates rotating the threaded rod 5 and guiding the driving plate 3 at the same time.

[0033] In the present utility model, during use, the workpiece to be processed is clamped and fixed by the three-jaw chuck 18. According to the length of the workpiece, the threaded rod 5 is rotated. The threaded rod 5 drives the transverse movement of the driving plate 3, the adjusting plate and the detection disc 6, so as to adjust the detection distance between the detection disc 6 and the three-jaw chuck 18, so as to calibrate and detect workpieces of different lengths. Then, the measuring rod 15 is abutted against the top of the workpiece, and the driving motor 17 is started. The driving motor 17 drives the rotation of the three-jaw chuck 18 and the workpiece. If the measuring rod 15, the slider 20, the connecting rod 14 and the cross plate 13 move, it means that the workpiece calibration is unqualified and the workpiece needs to be recalibrated and fixed. Through the displacement sensor 12, the movement of the cross plate 13 can be measured, and the data measured by the displacement sensor 12 is displayed on the display screen 11. Personnel can more clearly and intuitively detect the workpiece calibration situation through the data on the display screen 11, making the use effect better. On the contrary, during the rotation process, if the value of the displacement sensor 12 does not change, it means that the measuring rod 15 does not move, which further indicates that the workpiece calibration is good. Then, two ball rods 25 can be pulled outwards. The two ball rods 25 drive the two lifting plates 23 and the clamping plate 22 to move away from each other and disengage from the clamping groove 21, so as not to fix the limiting plate 9 and the mounting sleeve 8. At this time, the mounting sleeve 8 and the detection disc 6 can be detached from the cross bar 7, and then the workpiece can be processed, and at the same time, it is convenient to overhaul and replace it. When detection is required, due to the guiding and limiting of the limiting plate 9 and the limiting groove 26, the mounting sleeve 8 can be positioned and sleeved on the outside of the cross bar 7. When the mounting sleeve 8 is pushed to the right, at this time, the clamping plate 22 is automatically pressed and compresses the return spring 24. When it is completely sleeved, at this time, the clamping plate 22 is aligned with the clamping groove 21. Under the elastic force of the return spring 24, the two clamping plates 22 approach each other and are clamped in the clamping groove 21, so that the detection disc 6 can be installed on the cross bar 7 to detect the workpiece calibration.

[0034] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
