Description

Technical Field

[0001] This invention relates to the field of profilometer technology, and in particular to a profilometer with a multi-functional universal device. Background Technology

[0002] In the field of precision manufacturing and inspection, profilometers are key metrological devices used to acquire the surface profile shape, micro-morphology and geometric tolerances of parts. Their core function is to quantitatively collect and accurately analyze the surface profile shape, micro-geometric features and geometric tolerance parameters of various precision parts.

[0003] Existing conventional profilometers typically only have a high-precision X-axis horizontal feed mechanism and a Z-axis vertical lifting mechanism, which can only achieve linear scanning measurement in a single vertical plane. For non-forward measurement features such as inclined surfaces, side holes, and lateral curved surfaces, the measurement must be completed by manually clamping and realigning the parts multiple times. This not only significantly reduces the detection efficiency, but also introduces repeated positioning errors, which directly affects the stability of measurement accuracy. Therefore, there is an urgent need for a profilometer with a multi-functional universal device. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a profiler with a multi-functional universal device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A profilometer with a multi-functional universal device includes a base, an operation box on the top of the base, a lifting frame that can move vertically up and down in the middle of the operation box, a probe for measuring the contour of an object above the lifting frame, a data acquisition device for adjusting the probe above the lifting frame, a connecting component for supporting the data acquisition device below the data acquisition device, and a support mechanism for adjusting the height and angle of the connecting component between the connecting component and the lifting frame. The supporting mechanism is used to drive the connecting component to perform a secondary height adjustment after the lifting frame drives the connecting component to complete the height adjustment, and can also drive the connecting component to perform angle adjustment; The supporting mechanism includes a supporting plate fixed to the side of the lifting frame, a fixing plate above the supporting plate, a connecting platform above the fixing plate for fixing the connecting components, and a moving mechanism between the fixing plate and the connecting platform for driving the connecting components to move laterally or longitudinally. Between the fixed plate and the support plate, there are also several adjustment mechanisms that drive the connecting components to perform secondary lifting or horizontal angle adjustment. The number of adjustment mechanisms is adjusted according to the actual use, but the minimum number of adjustment mechanisms is three.

[0006] As a preferred technical solution of the present invention, the moving mechanism includes a secondary threaded rod that drives the connecting table to move laterally and reciprocally. A secondary moving block is screwed to the outside of the secondary threaded rod. The top of the secondary moving block is fixed to the bottom of the connecting table. A limiting plate for limiting the connecting table is also provided above the secondary threaded rod. The moving mechanism also includes a main threaded rod that drives the connecting table to move longitudinally and reciprocally. Two clamping plates that support the main threaded rod are fixed above the fixed plate. A main servo motor that drives the main threaded rod to rotate is fixed on the outer wall of one of the clamping plates. A main moving block is screwed onto the outer wall of the main threaded rod. A secondary servo motor that drives the secondary threaded rod to rotate is fixed on the side of the main moving block. The output shaft of the auxiliary servo motor is fixed to the auxiliary threaded rod, and the output shaft of the main servo motor is fixed to the main threaded rod. The limiting plate is fixed to the upper half of the main moving block, and a sliding groove adapted to the auxiliary moving block is opened in the middle of the limiting plate. The upper half of the auxiliary moving block extends through the sliding groove to the top of the limiting plate. When the connecting table needs to be moved longitudinally, the output shaft of the main servo motor drives the main threaded rod to rotate. The main moving block and the main threaded rod are driven to move longitudinally along the outer wall of the main threaded rod. The main moving block drives the limiting plate to move longitudinally. The limiting plate drives the auxiliary moving block and the auxiliary threaded rod to move longitudinally.

The baffle is fixed on the side of the fixed plate away from the clamping plate, the main moving block is fixed on the end of the limiting plate away from the baffle, and the clamping block is rotatably connected to the end of the auxiliary threaded rod away from the auxiliary servo motor. When the connecting platform needs to be moved laterally, the output shaft of the secondary servo motor drives the secondary threaded rod to rotate. The secondary moving block cooperates with the secondary threaded rod, causing the secondary moving block to move laterally along the outer wall of the secondary threaded rod. The secondary moving block drives the bottom of the connecting platform to move laterally, and the connecting platform drives the connecting assembly to move laterally.

The upper half of the inclined rod is also hinged to a transmission rod, and the end of the transmission rod away from the inclined rod is movably connected to the top of the transmission block. A movable rod is fixed to one end of the inclined rod near the auxiliary drive rod. A connecting shaft is provided in the middle of the inclined rod. The bottom of the main mounting base and the bottom of the auxiliary mounting base are fixed to the top of the support plate. A through groove adapted to the movable rod is opened in the middle of the auxiliary drive rod. The movable rod is slidably connected inside the through groove. When the telescopic end of the electro-hydraulic rod extends or retracts, the telescopic end of the electro-hydraulic rod drives the transmission block to move vertically up and down. The transmission block drives the transmission rod to rotate around the axis of the connecting shaft. The transmission rod drives the inclined rod to rotate around the top of the auxiliary mounting base through the connecting shaft. The inclined rod drives the movable rod to move along the inside of the through groove. The through slots of the main drive rod and the auxiliary drive rod engage, causing the auxiliary drive rod to rotate around the bottom of the support base. The auxiliary drive rod engages with the main drive rod, allowing them to switch between vertical and inclined states. When the main drive rod and the auxiliary drive rod are inclined and form an angle, the auxiliary drive rod drives the fixed plate downward through the support base, and the fixed plate drives the connecting assembly downward. When the main drive rod and the auxiliary drive rod are vertical and collinear, the auxiliary drive rod drives the fixed plate through the support base, the support base drives the fixed plate upward, and the fixed plate drives the connecting assembly upward, thus enabling secondary adjustment of the height of the connecting assembly.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention, through the cooperation of structures such as a data acquisition unit, probe, lifting frame, support mechanism, main drive rod, auxiliary drive rod, diagonal rod and transmission block, simultaneously realizes the height adjustment, planar horizontal and vertical displacement adjustment and multi-directional angle adjustment of the probe. Complex parts with multi-directional hole system, inclined surface and curved surface can complete the full feature measurement in only one clamping, eliminating the repeated positioning error introduced by multiple clamping, and greatly improving the detection efficiency and measurement accuracy stability; 2. This invention, through the cooperation of structures such as the connecting platform, main moving block, auxiliary moving block, main servo motor, auxiliary servo motor, main threaded rod, and auxiliary threaded rod, drives the probe to complete precise lateral and longitudinal displacement in the plane. It can adapt to the measurement needs of workpieces of different sizes and features to be measured at different positions without adjusting the workpiece position, effectively breaking through the limitation of the single scanning path of the traditional profilometer and expanding the measurement coverage of the equipment. 3. This invention, through the cooperation of structures such as electric hydraulic rod, main mounting base, main drive rod, auxiliary drive rod, support base, diagonal rod and transmission block, achieves secondary height fine adjustment of the probe through multiple sets of adjustment mechanisms, based on the original lifting frame's large stroke primary height adjustment. This retains the adaptability of large stroke height adjustment and makes up for the lack of precision of large stroke transmission, adapting to the precise alignment requirements of the test surface at different heights and significantly improving the adjustment accuracy in the height direction. 4. This invention, through the cooperation of structures such as an electric hydraulic rod, main mounting base, main drive rod, auxiliary drive rod, support base, diagonal rod and transmission block, and through the cooperation of multiple sets of adjustment mechanisms and universal swing support structure, can drive the probe to complete the horizontal and pitch angle adjustment in any direction. It can directly complete the scanning and measurement of complex features such as inclined surfaces, side holes, and spatial curved surfaces in multiple directions without rotating the workpiece, thus solving the core technical defect of traditional profilometers that can only scan a single plane in the forward direction. 5. This invention achieves angle swing by using a minimum of three adjustment mechanisms through the cooperation of structures such as a support mechanism, an electro-hydraulic rod, a main mounting base, a main drive rod, a secondary drive rod, a support base, a diagonal rod, a secondary mounting base, and a transmission block. Combined with the ball-joint connection between the swing ball and the pressure rod, the angle adjustment process is uniformly stressed and the support is stable. At the same time, it allows the fixed plate to swing flexibly in all directions, ensuring the stability and accuracy of the measurement posture. 6. This invention can be directly adapted and installed on the lifting frame of an existing conventional profilometer through a fixing plate, connecting plate and plug rod, without the need for major modifications to the original equipment body; at the same time, the configuration of the adjustment mechanism can be flexibly adjusted according to the actual load and accuracy requirements, adapting to the measurement needs of different scenarios, with low equipment upgrade and modification costs and wide applicability.

[0016] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0018] The connecting component 3 includes a base and a Y-axis lateral movement module, a horizontal rotation module, and a pitch adjustment module connected in sequence to form a compact integrated platform that can be stably installed on the main worktable of the profilometer. The Y-axis lateral movement module serves as the basis for left and right direction adjustment. Two high-precision linear guides are arranged in parallel on its rigid base. The lateral movement platform forms a sliding pair with the guides through a slider and is driven by a hand-cranked screw mechanism. The screw and nut pair connect the base and the lateral movement platform. Turning the handwheel can drive the lateral movement platform to move linearly. The matching locking device can lock it at any position to prevent measurement deviation. The horizontal rotation module is integrated above the transverse platform to achieve 360° planar rotation of the workpiece around the Z-axis, with both coarse and fine adjustment modes. Its core rotation platform is connected to the transverse platform through a slewing bearing. Releasing the matching brake device allows for manual and rapid rotation to complete coarse positioning. Through a clamping and resetting mechanism consisting of a precision adjusting screw and symmetrical compression springs, the small angular displacement of the rotation platform can be precisely adjusted. The pitch adjustment module is located above the rotation platform to clamp the workpiece and achieve its pitch movement around the horizontal axis. Its main workpiece mounting table is hinged to the rotation platform through the horizontal axis and adopts a crank-slider mechanism driven by a hand-cranked screw. The screw nut is hinged to the workpiece mounting table through a connecting rod. Cranking the screw drives the nut to rise and fall, thereby driving the mounting table to complete the pitch angle adjustment. Relying on the self-locking characteristic of the screw, any pitch angle can be stably maintained. During operation, the workpiece is fixed on the workpiece mounting table. After Y-axis horizontal movement for positioning and locking, horizontal rotation for coarse and fine adjustment for alignment, and pitch angle adjustment, measurement can be carried out. After single feature measurement is completed, each module can be directly adjusted to switch the feature surface to be measured without repeatedly disassembling and assembling the workpiece.

When it is necessary to drive the connecting component 3 to move laterally back and forth, the output shaft of the auxiliary servo motor 707 drives the auxiliary threaded rod 726 to rotate. The auxiliary moving block 725 is in transmission cooperation with the auxiliary threaded rod 726, so that the auxiliary moving block 725 moves laterally back and forth along the outer wall of the auxiliary threaded rod 726. Then, the auxiliary moving block 725 drives the connecting table 702 and the connecting component 3 to complete the lateral back and forth movement. When a secondary height adjustment of the connecting assembly 3 is required, the telescopic ends of several electro-hydraulic rods 714 extend and retract synchronously, driving the transmission block 723 to move vertically up and down. The transmission block 723 drives the transmission rod 722 to rotate around the axis of the connecting shaft. The transmission rod 722 drives the inclined rod 720 to rotate around the top of the auxiliary mounting base 721 through the connecting shaft. The inclined rod 720 drives the moving rod to move along the inside of the through groove. The moving rod engages with the through groove of the auxiliary drive rod 718, driving the auxiliary drive rod 718 to rotate around the bottom of the support base 719. The auxiliary drive rod 718 engages with the main drive rod 717, enabling the main drive... The main drive rod 717 and the auxiliary drive rod 718 switch between vertical and inclined states: When the main drive rod 717 and the auxiliary drive rod 718 switch to the inclined state and form an angle, the auxiliary drive rod 718 drives the fixed plate 701 to move downward through the support base 719, thereby driving the connecting assembly 3 to move downward synchronously; when the main drive rod 717 and the auxiliary drive rod 718 switch to the vertical collinear state, the auxiliary drive rod 718 drives the fixed plate 701 to move upward through the support base 719, thereby driving the connecting assembly 3 to move upward synchronously, thus completing the secondary adjustment of the height of the connecting assembly 3; When the angle of the connecting component 3 needs to be adjusted, first drive the electric hydraulic rods 714 corresponding to multiple sets of adjustment mechanisms to form an angle between each set of main drive rods 717 and auxiliary drive rods 718. Then, drive the telescopic end of one set of electric hydraulic rods 714 to rise and fall individually. The telescopic end of the electric hydraulic rod 714 drives the corresponding transmission block 723 to move vertically up and down. The transmission block 723 drives the transmission rod 722 to rotate around the axis of the connecting shaft. The transmission rod 722 drives the inclined rod 720 to rotate around the top of the auxiliary mounting base 721 through the connecting shaft. The inclined rod 720 drives the moving rod to move along the inside of the through groove. The moving rod cooperates with the through groove of the auxiliary drive rod 718, driving the auxiliary drive rod 718 to move along the through groove. The drive rod 718 rotates around the bottom of the support base 719, and the support base 719 drives one end of the corresponding connecting plate 709 to rise and fall, so that the connecting plate 709 rotates around the axis of the swing ball 713, switching from a horizontal state to an inclined state, thus completing the horizontal angle adjustment of the connecting plate 709; the connecting plate 709 drives the fixing plate 701 to switch from a horizontal state to an inclined state through the insertion rod 711, and the fixing plate 701 drives the connecting component 3 to tilt synchronously, which in turn drives the data acquisition device 4 to tilt synchronously, thus completing the horizontal angle adjustment of the connecting component 3, and finally realizing that the connecting component 3 drives the probe 5 to adjust the corresponding angle between it and the object to be detected.
