[0004] However, the aforementioned machine tool base level detection device relies on manual reading during detection, which results in large reading errors and low efficiency. Furthermore, it cannot adapt to linear guides of different widths, affecting the actual detection experience. Utility Model Content

[0005] The present invention aims to solve the problems mentioned in the background art by providing a machine tool base level detection device.

[0006] The specific technical solution is as follows:

[0007] A machine tool base level detection device includes: support rods located at both ends of the machine tool base body, a connecting plate fixedly connected between the two support rods, a groove provided on the lower surface of the connecting plate, a connecting slider slidably installed in the groove, a detection component detachably connected to the lower end of the connecting slider, and two linear guides provided on the upper surface of the machine tool base body.

[0008] In a preferred embodiment of this utility model, the lower surface of the connecting slider is provided with linkage blocks at both ends, the upper surface of the linkage blocks is inserted with fixing bolts, and the detection component is attached to one end of the lower surface of the linkage block and connected by fixing bolts.

[0009] As a preferred embodiment of this utility model, the connecting slider is provided with a first threaded hole, a lead screw is connected in the first threaded hole, and a motor is provided on one side of one of the two support rods, the output shaft of the motor is connected to one end of the lead screw.

[0010] In a preferred embodiment of this utility model, the detection component includes a detection slider and a connecting plate. The detection slider is slidably installed inside the linear rail. The connecting plate is detachably connected to one end of the lower surface of the linkage block. Telescopic plates are fixedly installed on the upper surfaces of the two detection sliders respectively. A displacement sensor is provided on the upper surface of the telescopic plate. The laser beam of the displacement sensor is focused on the center of the top surface of the linear rail.

[0011] As a preferred embodiment of this utility model, a first fixing block is installed at both ends of the lower surface of the connecting plate, and a second fixing block is installed at one end of the lower surface of each of the two telescopic plates. A through hole is provided at one center end of the first fixing block, and a threaded cylinder is fixedly installed in the through hole. A second threaded hole is provided in the threaded cylinder, and a screw is threadedly connected in the second threaded hole. A ball spline is rotatably connected to the other end of the screw. The ball spline is rotatably installed on one side of the second fixing block. Two guide rods are installed at both ends of one side of the second fixing block, and the other ends of the two guide rods are inserted through one side of the first fixing block.

[0012] As a preferred embodiment of this utility model, two stabilizing guide rods are fixedly installed on one side of each of the two telescopic plates, and the other end of the stabilizing guide rod is inserted into one side of the connecting plate. A central counterweight is installed at the center of the lower surface of the connecting plate, and the displacement sensor is model KEYENCEGT-H10.

[0013] This utility model has the following beneficial effects:

[0014] 1. The machine tool base level detection device provided by this utility model, through the design of support rods, detection components, and linkage blocks, forms a detection frame spanning the base by moving the support rods to both ends of the machine tool base body during detection. This facilitates movement and improves detection efficiency. Then, the detection component is slidably installed on the linear guide and connected to the linkage block. The motor drives the lead screw to rotate, which moves the connecting slider in the slide groove, causing the detection component to move along with it. Data is collected by scanning the linear guide through the detection component. This eliminates the need for workers to place the level point by point, avoids missing local defects, and allows the linear guide to be covered by the detection component on the detection surface.

[0015] 2. The machine tool base level detection device provided by this utility model, through the design of a detection slider, displacement sensor, telescopic plate, and screw, allows the operator to rotate the screw to move it within a threaded cylinder. Since the other end of the screw is connected to a ball spline, it drives the telescopic plate on the second fixed block to move laterally to adjust the width. During the movement, the guide rod improves stability, allowing the detection slider mounted on the lower surface of the telescopic plate to slide and be mounted on the linear guide. Then, driven by a lead screw, it moves along the linear guide and is detected by the displacement sensor, which emits a laser beam. The sensor continuously focuses on the center of the top surface of the linear guide. If there is a horizontal deviation in the machine tool base, the height of the top surface of the linear guide at different positions will change. The displacement sensor converts the height change into an electrical signal through the time difference of laser beam reflection or the change of light intensity, and transmits it to the external control system in real time. The stabilizing guide rods on both sides of the telescopic plate are always inserted into the connecting plate to form a multi-support guide structure, which suppresses the lateral vibration that may be caused by the screw drive and ensures that the focal point of the sensor laser beam is stable and does not deviate. The central counterweight can improve the stability during the movement, thereby improving the detection accuracy. It can adapt to linear guides of different widths and eliminate errors caused by human reading. Attached Figure Description

[0029] Example 1

[0030] The machine tool base level detection device provided in this embodiment, such as Figures 1-5As shown, the machine tool base body 1 includes: support rods 2 located at both ends of the machine tool base body 1; a connecting plate 201 fixedly connected between the two support rods 2; a groove 205 provided on the lower surface of the connecting plate 201; a connecting slider 204 slidably installed in the groove 205; a detection component 3 detachably connected to the lower end of the connecting slider 204; and two linear guides 101 provided on the upper surface of the machine tool base body 1. Linkage blocks 206 are provided at both ends of the lower surface of the connecting slider 204; a fixing bolt 207 is inserted into the upper surface of the linkage block 206; and the detection component 3 is attached to one end of the lower surface of the linkage block 206 and connected by the fixing bolt 207. A first threaded hole is provided inside the connecting slider 204; a lead screw 203 is connected to the first threaded hole; and a motor 202 is provided on one side of one of the support rods 2; the output shaft of the motor 202 is connected to one end of the lead screw 203.

[0031] Through the design of support rod 2, detection component 3, and linkage block 206, when inspecting the machine tool base body 1, the support rod 2 is moved to both ends of the machine tool base body 1 to form a detection frame spanning the base, which facilitates movement and improves inspection efficiency. Then, the detection component 3 is slidably installed on the linear guide 101 and connected to the linkage block 206. The motor 202 is started to drive the lead screw 203 to rotate, which drives the connecting slider 204 to move in the slide groove 205, so that the detection component 3 moves along with it. Data is collected by scanning the linear guide 101 through the detection component 3, so that the worker does not need to place the level point by point, and there will be no missed detection of local defects. The detection component 3 can cover the detection surface of the linear guide 101.

[0032] Example 2

[0033] The machine tool base level detection device provided in this embodiment, such as Figures 2-5As shown, the detection component 3 includes a detection slider 301 and a connecting plate 304. The detection slider 301 is slidably installed inside the linear guide 101. The connecting plate 304 is detachably connected to one end of the lower surface of the linkage block 206. Telescopic plates 303 are fixedly installed on the upper surfaces of the two detection sliders 301 respectively. A displacement sensor 302 is provided on the upper surface of the telescopic plate 303. The laser beam of the displacement sensor 302 is focused on the center of the top surface of the linear guide 101. First fixing blocks 307 are installed at both ends of the lower surface of the connecting plate 304. Second fixing blocks 308 are installed at one end of the lower surface of each of the two telescopic plates 303. The center end of the first fixing block 307 has a through hole, in which a threaded cylinder 312 is fixedly installed. The threaded cylinder 312 has a second threaded hole, in which a screw 310 is threadedly connected. The other end of the screw 310 is rotatably connected to a ball spline 311, which is rotatably installed on one side of the second fixing block 308. Two guide rods 309 are installed at both ends of one side of the second fixing block 308, and the other ends of the two guide rods 309 are inserted into one side of the first fixing block 307. Two stabilizing guide rods 305 are fixedly installed on one side of each of the two telescopic plates 303. The other end of the stabilizing guide rods 305 is inserted into one side of the connecting plate 304. A central counterweight 306 is installed at the center of the lower surface of the connecting plate 304. The displacement sensor 302 is a KEYENCEGT-H10.

[0034] By designing the detection slider 301, displacement sensor 302, telescopic plate 303, and screw 310, operators can rotate the screw 310 to move it within the threaded cylinder 312. Since the other end of the screw 310 is connected to a ball spline 311, it drives the telescopic plate 303 on the second fixed block 308 to move laterally to adjust the width. During movement, the guide rod 309 improves stability, allowing the detection slider 301, mounted on the lower surface of the telescopic plate 303, to slide and adapt to the width on the linear guide 101. Then, driven by the lead screw 203, it moves along the linear guide 101 and is detected by the displacement sensor 302, which emits a laser beam. The laser beam is continuously focused on the center of the top surface of the linear guide 101. If there is a horizontal deviation in the machine tool base, the height of the top surface of the linear guide 101 at different positions will change. The displacement sensor 302 converts the height change into an electrical signal through the time difference of laser beam reflection or the change in light intensity, and transmits it to the external control system in real time. The stabilizing guide rods 305 on both sides of the telescopic plate 303 are always inserted into the connecting plate 304 to form a multi-support guide structure, which suppresses the lateral vibration that may be caused by the transmission of the lead screw 203, and ensures that the focal point of the sensor laser beam is stable and does not deviate. The central counterweight 306 can improve the stability during the movement, thereby improving the detection accuracy. It can adapt to linear guides 101 of different widths and eliminate errors caused by human reading.

[0035] In summary, the machine tool base level detection device provided in this embodiment has the following advantages: it can be adjusted according to the width of the linear guide 101, adapting to linear guides 101 of different widths, thus improving applicability; and it can eliminate errors caused by human reading, thereby improving its detection efficiency.

[0036] In use, by moving the support rod 2 to both ends of the machine tool base body 1, a detection frame spanning the base is formed. During use, the operator can rotate the screw 310 to make it rotate and move within the threaded cylinder 312. Since the other end of the screw 310 is connected to the ball spline 311, it will drive the telescopic plate 303 on the second fixed block 308 to move laterally to adjust the width. During the movement, the guide rod 309 can improve stability, allowing the detection slider 301 mounted on the lower surface of the telescopic plate 303 to slide and be used on the linear guide 101 to adapt to the width. Then, the connecting plate 304 is connected to the linkage block 206, and the motor 202 is started to drive the lead screw 203 to rotate, which drives the connecting slider 204 to move in the slide groove 205, so that it moves along the linear guide 101 and is detected by the displacement sensor 302. The laser beam emitted by the sensor is continuously focused on the center of the top surface of the linear guide 101. If there is a horizontal deviation in the machine tool base, the height of the top surface of the linear guide 101 at different positions will change. The displacement sensor 302 converts the height change into an electrical signal through the time difference of laser beam reflection or the change of light intensity and transmits it to the external control system in real time.

[0037] The external control system includes a touch screen and a PLC controller, which are electrically connected to the displacement sensor 302 and the touch screen, respectively.

[0038] The working principle of the control system is as follows:

[0039] When the displacement sensor 302 detects changes in the height of the top surface of the machine tool base linear guide 101 at different positions and converts these changes into electrical signals, the signals are transmitted to the external control system. At this point, the control system begins processing and feeding back the signals.

[0040] 1. Signal Reception and Processing: As the core of the control system, the PLC controller receives the electrical signal transmitted by the displacement sensor 302, converts the analog electrical signal into a digital signal (A / D conversion), and analyzes and processes the digital signal according to the preset algorithm and parameters to calculate the actual height value of each detection point of the linear guide 101 and the deviation from the standard horizontal height.

[0041] 2. Data Display and Interaction: Processed data is transmitted to a touchscreen display in real time, which shows the horizontal status of track 101 in a visual format (such as dynamic curves, data tables, etc.). Staff can intuitively view the height data, deviation values, and overall levelness of each detection point through the touchscreen display. They can also select different detection modes and set detection parameters through touch operation.

[0042] 3. Alarm and Feedback: The PLC controller compares the calculated deviation with a preset alarm threshold. If the deviation exceeds the threshold, the PLC controller immediately triggers the alarm mechanism, displaying an alarm message on the touch screen. Simultaneously, it can activate an audible and visual alarm to alert the operator that the horizontal deviation of the linear guide 101 exceeds the allowable range. Furthermore, the PLC controller can output control signals to drive external adjustment devices (such as jacks, adjusting bolts, etc., if the system is equipped with relevant adjustment devices) to automatically or assistedly adjust the machine tool base to reduce horizontal deviation.
