Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gap detection devices, specifically a ball screw machining gap detection device. Background Technology
[0002] The ball screw machining clearance detection device is a precision testing device specifically designed to measure the axial clearance of ball screw pairs after machining. Its core function is to quantify the clearance value of the ball screw through a precise mechanical structure and sensing system, determine whether it meets the design accuracy requirements, and provide a basis for subsequent assembly, adjustment, or quality assessment.
[0003] Traditional ball screw machining clearance detection devices typically have simple clamping structures, often employing manual bolt fastening or unidirectional mechanical clamping. This makes them unsuitable for ball screws of different diameters and lengths. When inspecting workpieces of different specifications, frequent changes of clamping accessories are required, resulting in cumbersome and time-consuming operations. After traditional inspection, the workpieces must be manually judged for compliance before being manually moved to different areas—the qualified and unqualified product areas—which is both time-consuming and labor-intensive. Especially during batch inspection, the efficiency bottleneck of manual sorting becomes prominent. Manual sorting relies on the operator's memory or recording of the inspection results, which may lead to "qualified products being mixed with unqualified products" or vice versa due to fatigue or negligence, affecting subsequent production processes. Utility Model Content
[0004] The purpose of this invention is to provide a ball screw processing clearance detection device, which has the advantage of rapid sorting and solves the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A ball screw machining clearance detection device includes a detection platform. A control box is installed at the lower end of the detection platform. A bidirectional clamping assembly is installed on the control box to fix the ball screw whose machining clearance needs to be detected. A protective support plate is installed at the upper end of the detection platform. A lifting detection assembly is installed on the protective support plate. A pushing and transporting assembly is installed on the detection platform to classify and transport qualified and unqualified products after detection. A controller is installed on the detection platform. A servo motor is installed at one end of the control box. A threaded adjusting rod is installed at the output end of the servo motor. A moving sleeve is threadedly connected to the outside of the threaded adjusting rod.
[0006] Preferably, the detection platform has a through-hole sliding groove, and the upper end of the movable sleeve is fixedly connected to a horizontal slider that slides inside the sliding groove.
[0007] It is worth noting that the sliding groove, in conjunction with the transverse slider, provides a sliding track for the moving sleeve, enabling the moving sleeve to move stably laterally within the testing platform. However, it is necessary to keep the inside of the sliding groove clean to prevent debris from entering and affecting the smoothness of sliding. Regular lubrication of the sliding parts is also necessary to reduce wear and extend service life.
[0008] Preferably, the bidirectional clamping assembly includes a movable disk mounted on the upper end of the horizontal slider, a bidirectional cylinder mounted on the upper end of the movable disk, and a protective base plate mounted on the upper end of the bidirectional cylinder.
[0009] It is worth noting that the movable plate is used to support the bidirectional cylinder, which allows for easy adjustment of the clamping position. However, it is important to ensure a stable air supply and pressure within the specified range when the bidirectional cylinder is in operation. Regular checks of the cylinder's sealing performance are necessary to prevent air leakage from affecting the clamping force.
[0010] Preferably, a positioning plate is installed at the center of the upper end of the protective base plate, and two sets of symmetrically arranged limiting grooves are opened through the interior of the protective base plate.
[0011] It is worth noting that the positioning plate is used for initial positioning of the ball screw, so that the ball screw can be accurately placed in the test position, which facilitates subsequent clamping and testing operations; however, it should be noted that the surface of the positioning plate should be kept flat and smooth to avoid scratching the surface of the ball screw.
[0012] Preferably, the output end of the bidirectional cylinder is equipped with two sets of limiting sliders, the upper end of the limiting slider is fixedly connected with a side protective plate, a supporting crossbar is installed on the inner side of the side protective plate, and an anti-slip clamping side plate is installed on the inner side of the supporting crossbar.
[0013] It is worth noting that the limiting slider slides within the limiting groove and is driven by a bidirectional cylinder, which moves components such as the side protective plate. However, it is important to note that if the anti-slip clamping side plate is severely worn, it should be replaced in time to ensure clamping force and anti-slip effect.
[0014] Preferably, the lifting detection component includes a lifting cylinder installed on the top of the protective support frame plate, vertical movable grooves are provided on the inner walls of both sides of the protective support frame plate, and a lifting plate is installed at the output end of the lifting cylinder.
[0015] It is worth noting that the lifting cylinder provides lifting power, driving the lifting plate to move up and down along the vertical movable groove, thereby moving the detection head mounted on the lifting plate closer to or away from the ball screw, realizing the detection of the gap at different parts of the ball screw; however, it is necessary to ensure that the air source of the lifting cylinder is stable, and to regularly check the fit clearance between the vertical movable groove and the guide slider. If the clearance is too large, it is necessary to adjust or replace the parts in time to ensure the lifting accuracy.
[0016] Preferably, both sides of the lifting plate are fixedly connected to guide sliders that slide inside the vertical movable groove, and a detection head is installed at the lower end of the lifting plate.
[0017] It is worth noting that the detection head is used to directly detect the machining clearance of the ball screw and feeds the detection data back to the control system; however, the detection head is a precision component and should be protected from impacts and excessive wear. Regular calibration is necessary to ensure detection accuracy. The guide slider requires lubrication and cleaning to prevent jamming.
[0018] Preferably, the push and transport component includes two sets of mounting side plates installed on both sides of the upper end of the detection platform. Push hydraulic rods are installed on the side ends of the mounting side plates, and arc-shaped push side plates are installed at the output ends of the push hydraulic rods. Two sets of inclined guide plates are installed on the upper end of the detection platform at positions corresponding to the two sets of arc-shaped push side plates, and belt conveyors are installed on the sides of the inclined guide plates.
[0019] It is worth noting that the inclined guide plate guides the ball screw to the belt conveyor, realizing the classified conveying of qualified and unqualified products; however, it is necessary to regularly check the belt tension and wear of the belt conveyor to ensure normal operation.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The bidirectional clamping assembly in this invention can fix the ball screw to be tested. Through bidirectional synchronous clamping, it ensures that the screw axis is consistent with the testing reference, avoiding workpiece shaking or displacement during the testing process. Compared with traditional unidirectional clamping, bidirectional force is more uniform, can adapt to screws of different diameters, has strong versatility, and the clamping force can be adjusted to avoid damaging the workpiece surface. The push and transport assembly automatically classifies and transports qualified and unqualified products to different areas after testing, eliminating the need for manual sorting. This achieves high precision, high efficiency, and high automation in ball screw gap testing. Compared with traditional manual testing devices, it has significant advantages in consistency, stability, and adaptability. Attached Figure Description

[0025] The bidirectional clamping assembly includes a movable disk 301 mounted on the upper end of the transverse slider 204. A bidirectional cylinder 302 is mounted on the upper end of the movable disk 301. A protective base plate 303 is mounted on the upper end of the bidirectional cylinder 302. A positioning plate 304 is mounted at the center of the upper end of the protective base plate 303. Two sets of symmetrically arranged limiting grooves 305 are opened through the interior of the protective base plate 303. Two sets of limiting sliders 306 are mounted on the output end of the bidirectional cylinder 302. A side protective plate 307 is fixedly connected to the upper end of the limiting slider 306. A support crossbar 308 is mounted on the inner side of the side protective plate 307. An anti-slip clamping side plate 309 is mounted on the inner side of the support crossbar 308.
[0026] The lifting detection assembly includes a lifting cylinder 501 installed on the top of the protective support plate 4. Vertical movable grooves 502 are provided on the inner walls of both sides of the protective support plate 4. A lifting plate 503 is installed at the output end of the lifting cylinder 501. Guide sliders 504 that slide inside the vertical movable grooves 502 are fixedly connected to both sides of the lifting plate 503. A detection head 505 is installed at the lower end of the lifting plate 503.
[0027] The push and transport component includes two sets of mounting side plates 601 installed on both sides of the upper end of the detection platform 1. Pushing hydraulic rods 602 are installed on the side ends of the mounting side plates 601. Arc-shaped push side plates 603 are installed at the output ends of the pushing hydraulic rods 602. Two sets of inclined guide plates 604 are installed at the upper end of the detection platform 1 at positions corresponding to the two sets of arc-shaped push side plates 603. Belt conveyors 605 are installed on the sides of the inclined guide plates 604.
[0028] Working principle: First, the ball screw to be tested is placed on the positioning plate 304. The controller 6 starts the device, and the control box 2 starts to supply power and coordinate the work of each component. Then, the controller 6 controls the bidirectional cylinder 302 to start. Its output end drives the two sets of limit sliders 306 to slide in the limit groove 305, thereby causing the side protection plate 307 and the support crossbar 308 to drive the anti-slip clamping side plate 309 to move inward, clamping and fixing the ball screw on the positioning plate 304 in both directions. The protective base plate 303 protects the clamping components. At this time, the servo motor 201 starts, driving the threaded adjustment rod 202 to rotate, so that the moving sleeve 203 slides laterally in the sliding groove 101 of the detection platform 1 through the transverse slider 204, thereby driving the moving disk 301 and the ball screw fixed above to the detection position directly below the detection head 505. The controller 6 controls the lifting cylinder 501 on the top of the protective support plate 4 to start, and its output end pushes the lifting plate 503, so that the guide sliders 504 on both sides of the lifting plate 503 slide in the vertical movable groove 502, which drives the detection head 505 to descend to contact the ball screw. The detection head 505 detects the machining clearance of the ball screw and feeds the data back to the controller 6. Then the controller 6 analyzes the detection data and determines whether the ball screw is a qualified product or a non-qualified product. If the product is qualified, the controller 6 activates the push hydraulic rod 602 on the corresponding mounting side plate 601, pushing the arc-shaped push side plate 603 to push the ball screw to the corresponding inclined guide plate 604. The ball screw then slides through the inclined guide plate 604 to the belt conveyor 605 on the same side and is transported away. If the product is unqualified, the push hydraulic rod 602, arc-shaped push side plate 603, inclined guide plate 604, and belt conveyor 605 on the other side operate in the same manner. After the inspection is completed, the lifting cylinder 501 drives the lifting plate 503 and the inspection head 505 to rise and reset. The bidirectional cylinder 302 drives the anti-slip clamping side plate 309 and other components to reset and release. The servo motor 201 drives the relevant components to reset, waiting for the next inspection.
