Description

Technical Field

[0001] This utility model relates to the field of coordinate measuring technology, and in particular to a coordinate auxiliary measuring device suitable for the inspection of direct parts. Background Technology

[0002] In manufacturing, the quality of directly manufactured parts directly impacts equipment performance and stability, making high-precision manufacturing and reliability crucial. Coordinate measuring machine (CMM) technology, due to its high precision, flexibility, and comprehensive measurement capabilities, has become a core industrial measurement tool. CMM-assisted measurement systems integrate advanced hardware and intelligent software to provide efficient solutions for directly manufactured part inspection. A CMM obtains coordinate points by contacting the workpiece with a probe in the X, Y, and Z coordinate systems, and then uses mathematical calculations to derive dimensions, shape, and position parameters. Trigger-type probes record coordinates instantaneously upon contact with the workpiece, while scanning probes can continuously acquire dense point cloud data. For example, in measuring the bore diameter of directly manufactured parts in automotive engine blocks, trigger-type probes accurately measure dimensions, while scanning probes acquire shape error information such as roundness and cylindricity.

[0003] Patent publication number "CN222298761U" discloses "A Measurement Auxiliary Structure for a Coordinate Measuring Instrument," which includes a measuring platform. A mounting base is fixedly installed on the top of the measuring platform, and an adjusting rod is rotatably installed on the bottom of the measuring platform. The bottom of the adjusting rod is fixedly connected to the output end of a drive motor. A connecting rod is fixedly installed at the top end of the adjusting rod, and a mounting plate is fixedly installed on the top of the connecting rod. An annular groove for sliding the connecting rod is formed on the measuring platform corresponding to the position of the mounting plate. A coordinate measuring instrument for measurement is fixedly installed on the top of the mounting plate. The device also includes a connecting assembly and a clamping assembly. Through the cooperation of the above structures, this device effectively improves the accuracy and stability of the measurement while facilitating the fixation and support of the workpiece and preventing its movement and deformation during measurement. It also increases the efficiency of workpiece inspection and is more convenient and practical.

[0004] When installing the device described in the aforementioned patent, simply align the bottom of the placement base with the positions of several clamping blocks, and then rotate the lead screw to drive the clamping blocks to slide inside the adjustment groove until the ends of the clamping blocks and the slots are engaged with the bottom of the placement base. This completes the installation and fixation, making installation and disassembly quicker and more convenient. If the placement base is frequently replaced and multiple sets of lead screws are repeatedly rotated, not only will the operation be cumbersome and reduce efficiency, but excessive wear of the lead screw may also cause thread stripping, reduced clamping force, etc. In severe cases, it may cause the placement base to loosen, and in batch operations, it may reduce production efficiency, affecting the continuity of the production line and capacity utilization. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a coordinate measuring machine (CMM) auxiliary measuring device suitable for the inspection of direct-access parts.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a three-coordinate auxiliary measuring device suitable for the inspection of direct parts, including a worktable, a rotating mechanism provided below the worktable, and an adjustment mechanism provided on the surface of the worktable;

[0009] The adjustment mechanism includes a support block and a servo hydraulic cylinder. One end of the servo hydraulic cylinder is fixedly installed on one side surface of the support block. The output end of the servo hydraulic cylinder is slidably connected through one side surface and the other side surface of the support block. Push plates are fixedly installed on the output end of the servo hydraulic cylinder. A detection table is placed on the surface of the worktable. The inner surface of the push plate abuts against the outer surface of the detection table.

[0010] By adopting the above technical solution, the push plates installed at the output end are displaced by servo hydraulic cylinders. The inner side of the displaced push plates abuts against the outer side of the inspection table. The stable thrust of the hydraulic system can quickly release the locking state of the inspection table, realizing convenient replacement of the inspection table, greatly shortening downtime. This solves the problems of frequent replacement of the placement seat and repeated rotation of multiple sets of lead screws, which not only makes the operation cumbersome and reduces efficiency, but may also cause thread stripping and clamping force reduction due to excessive wear of the lead screws. In severe cases, it may cause the placement seat to loosen. In batch operations, it can also reduce production efficiency and affect the continuity of the production line and capacity utilization.

[0011] As a preferred embodiment of the coordinate measuring machine (CMM) for direct component inspection described in this utility model, the rotating mechanism includes an annular groove and a rotating wheel. The outer side of the rotating wheel is rotatably connected to the inner side of the annular groove. A servo motor and a connecting rod are respectively arranged below the worktable. The two ends of the connecting rod are respectively fixedly installed on both sides of the output end of the servo motor. The bottom end of the rotating wheel is fixedly installed on the surface of the connecting rod. A CMM is fixedly installed on the top end of the rotating wheel.

[0012] By adopting the above technical solution, the connecting rods on both sides of the output end are driven to rotate by the servo motor. The rotating connecting rods can drive the rotating wheel mounted on the surface to make circular motion in the annular groove. The rotating wheel effectively reduces the frictional resistance with the annular groove through rolling contact, thereby ensuring that the coordinate measuring machine mounted on the top of the rotating wheel rotates synchronously and smoothly, significantly improving the flexibility and coverage of multi-directional measurement.

[0013] As a preferred embodiment of the coordinate measuring machine for direct component inspection described in this utility model, the annular groove of the rotating mechanism is formed on the surface of the worktable and extends through the bottom surface, and the output end of the servo motor is rotatably connected to the bottom surface of the worktable.

[0014] By adopting the above technical solution, the worktable can provide an effective opening position for the annular groove that penetrates the bottom surface.

[0015] As a preferred embodiment of the three-coordinate auxiliary measuring device for direct component inspection described in this utility model, the bottom surface of the support block of the adjustment mechanism is fixedly installed on the surface of the worktable, and the bottom surface of the push plate is slidably connected to the surface of the worktable.

[0016] By adopting the above technical solution, the workbench can provide a stable fixed position for the support blocks installed on the surface.

[0017] As a preferred embodiment of the coordinate measuring machine for direct component inspection described in this utility model, a support frame is fixedly installed on the bottom surface of the worktable, and the bottom end of the servo motor of the adjustment mechanism is fixedly installed on the surface of the support frame.

[0018] By adopting the above technical solution, the support frame can effectively support the weight from the workbench and equipment.

[0019] As a preferred embodiment of the three-coordinate auxiliary measuring device for direct component inspection described in this utility model, an auxiliary groove is provided on the bottom surface of the worktable, and auxiliary wheels are rotatably connected to the inner side of the auxiliary groove. The bottom ends of the auxiliary wheels are fixedly installed on the connecting rod surface of the adjustment mechanism.

[0020] By adopting the above technical solution, the rotating connecting rod synchronously drives the auxiliary wheels installed on the surface to make circular motion in the auxiliary groove. This limiting structure provides precise guidance and support for the connecting rod and the rotating mechanism, ensuring the stability and reliability of the motion trajectory.

[0021] (III) Beneficial Effects

[0023] 1. By adding an adjustment mechanism, the push plates installed at the output end are displaced by a servo hydraulic cylinder. The inner side of the displaced push plate abuts against the outer side of the inspection table. The stable thrust of the hydraulic system can quickly release the locking state of the inspection table, realizing convenient replacement of the inspection table, greatly shortening downtime. This solves the problems of frequent replacement of the placement seat and repeated rotation of multiple sets of lead screws, which not only makes the operation cumbersome and reduces efficiency, but may also cause thread stripping and clamping force reduction due to excessive wear of the lead screws. In severe cases, it may cause the placement seat to loosen, and in batch operations, it may reduce production efficiency, affecting the continuity of the production line and capacity utilization.

[0024] 2. By adding a rotating mechanism, the connecting rods on both sides of the output end are driven to rotate by a servo motor. The rotating connecting rods can drive the rotating wheel mounted on the surface to make circular motion in the annular groove. The rotating wheel effectively reduces the frictional resistance with the annular groove through rolling contact, thereby ensuring that the coordinate measuring machine mounted on the top of the rotating wheel rotates synchronously and smoothly, significantly improving the flexibility and coverage of multi-directional measurement.
