Description

Technical Field

[0001] This utility model mainly relates to the field of coordinate measuring technology, specifically to a measuring device for measuring the dimensions of non-standard workpieces. Background Technology

[0002] In the process management of machining non-standard workpieces, a coordinate measuring machine can be used to sample and measure the dimensions of the target surface of the workpiece, which requires leveling.

[0003] An existing patent (publication number: CN217980113U) discloses a coordinate measuring machine (CMM) capable of measuring non-horizontal surface workpieces. The CMM includes a base with a mounting groove at the top. A support column is fixedly connected to the center of the bottom of the mounting groove. A mounting platform is located within the mounting groove. A first universal ball is integrally formed at the center of the bottom of the mounting platform, movably connected to the top of the support column. An adjusting hydraulic cylinder is hinged to the bottom of the mounting groove at each of the four corners of the mounting platform's bottom. The bottom of the mounting platform is hinged to the piston rods of the four adjusting hydraulic cylinders. This invention allows for multi-angle and wide-range adjustment of the mounting platform's tilt angle using four adjusting hydraulic cylinders located below the mounting platform, meeting the measurement needs of non-horizontal surface workpieces, thus increasing the applicability of the CMM. An auxiliary device is also provided to assist in adjusting the angle of the mounting platform.

[0004] In current technology, the tilt angle of the mounting platform is adjusted, and the mounting platform and the measuring structure form a complete coordinate measuring machine. The mounting platform needs to be kept horizontal and stable. Adjusting the mounting platform will cause the measurement uncertainty of the coordinate measuring machine to become uncontrollable, affecting the accuracy of subsequent inspection results and making it unfavorable for the inspection of workpieces with non-horizontal surfaces.

[0005] The inventor proposes a measuring device for measuring the dimensions of non-standard workpieces. To meet the measurement needs of non-horizontal surfaces of workpieces, an auxiliary support structure can be added to the marble base to facilitate the user's adjustment of the measured position of the workpiece and facilitate the inspection of non-horizontal surfaces of the workpiece.

[0039] See attached document Figure 1-4 This utility model provides a measuring device for measuring the dimensions of non-standard workpieces, comprising the following structure:

[0040] A coordinate measuring machine 1 has a marble base 2 fixedly mounted at the bottom center, and a front frame 3 is detachably attached to the left side of the marble base 2.

[0041] Guide frame 4, with multiple slide blocks 5 slidably connected in the middle of guide frame 4.

[0042] Angle iron 6 has multiple limiting holes fixed on its outer side from top to bottom. A connecting screw 7 is inserted into the outer side of angle iron 6. A connecting plate 8 is fixed on the right side of the connecting screw 7. A supporting screw 9 is fixed on the bottom right side of the connecting plate 8.

[0043] In this embodiment, the bottom of the guide frame 4 is detachably snapped to the top of the front frame 3. The top of the guide frame 4 is fixedly provided with a guide hole 41, and the middle of the guide frame 4 is fixedly provided with a guide groove that cooperates with the slide 5. The top of the inner wall of the guide groove extends to the bottom of the guide hole 41.

[0044] The guide groove of the guide frame 4 provides a moving guide for the sliding of the slide block 5. The guide hole 41 cooperates with the connecting column 52 to facilitate the sliding of the slide block 5 to move the angle iron 6 and other structures outside the marble base 2.

[0045] In this embodiment, a limit bolt 51 is threadedly connected to the middle of the slide block 5. The right side of the limit bolt 51 abuts against the middle of the guide frame 4. A connecting post 52 is fixedly provided on the top of the slide block 5. The top of the connecting post 52 passes through the bottom to the top of the guide hole 41.

[0046] The limit bolt 51 and the slide 5 work together to lock the working position of the slide 5 on the guide frame 4.

[0047] In this embodiment, a docking seat 61 is welded to the bottom of the angle iron 6. The bottom of the docking seat 61 is movably connected to the top of the connecting post 52. A limiting pin 62 is inserted into the outer side of the docking seat 61. The middle part of the limiting pin 62 is detachably snapped into the middle part of the connecting post 52.

[0048] The docking seat 61 cooperates with the connecting column 52 through the limiting pin 62 to complete the assembly of the angle iron 6 on the top of the slide 5.

[0049] In this embodiment, the left end of the docking screw 7 is threaded with a docking nut 71, the right side of the docking nut 71 abuts against the left side of the angle iron 6, and the axial direction of the docking screw 7 is parallel to the axial direction of the support screw 9.

[0050] The assembly of the connecting screw 7 and the connecting nut 71 on the outside of the angle iron 6 completes the adjustment of the working position of the support screw 9 above the marble base 2. The design of the connecting plate 8, combined with the parallel design of the connecting screw 7 and the support screw 9, makes it convenient for users to make further adjustments to the working position of the support screw 9.

[0051] In this embodiment, a support nut 91 is threadedly connected to the outer side of the support screw 9, and a sleeve 92 is welded to the right end of the support nut 91. The middle part of the sleeve 92 is movably sleeved with the outer side of the support screw 9, and support rings 93 are fixed at equal intervals on the outer side of the sleeve 92.

[0052] According to the measurement requirements of the non-standard workpiece placed on the marble base 2, the working position of the slide 5 on the guide frame 4 is adjusted. According to the support requirements of the non-standard workpiece, the docking screw 7 and the docking nut 71 work together to adjust the working height of the support screw 9 on the marble base 2. The docking screw 7, the connecting plate 8 and the support screw 9 work together to bring the sleeve 92 and the support ring 93 close to the non-standard workpiece, providing support for the non-standard workpiece. This allows the worker to adjust the measured surface of the non-standard workpiece towards the detection end of the coordinate measuring machine 1 by adjusting the level.

[0053] A support ring 93 is set on the outside of the sleeve 92 to increase the friction between the non-standard workpiece and the sleeve 92, so as to avoid the non-standard workpiece sliding due to the sleeve 92 being unable to stably support the non-standard workpiece during the dimensional measurement process, which would affect the test results.

[0054] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
