Description

Technical Field

[0001] The utility model relates to the technical field of contour measuring tools, in particular to a facial contour measuring tool suitable for workpieces of various sizes. Background Art

[0002] The turbine shell is a transitional element connecting the exhaust pipe and the intermediate shell, and is also a protective cover for the alloy impeller. The assembly precision of the turbine shell is relatively high. After the turbine shell is processed, the precision of the turbine shell needs to be tested to ensure the safety of subsequent use.

[0003] The patent with announcement number CN220304513U discloses a universal inspection tool for the contour of a large turbine shell surface, which relates to the technical field of contour inspection tools, including a base, a screw nut mounting block, a contour detector, and a placement groove on the surface of the base. The utility model uses the screw nut sleeve and the support wheel in combination, so that the user can adjust the position of the support wheel according to the overall diameter of the turbine, thereby facilitating the subsequent rotation of the turbine, and thus facilitating the contour detection instrument to detect the overall contour of the turbine. At the same time, the use of a universal ball and an extrusion disc can prevent the turbine from being offset during the detection process, thereby ensuring the quality of the detection. At the same time, the extrusion disc can drive the turbine to rotate as a whole, thereby facilitating the detection of the outer wall contour of the turbine. At the same time, the device can adjust the position of the turbine through the extrusion disc and the universal ball clamp, thereby enabling the device to reduce the time required for the user to re-fix the turbine, thereby improving the efficiency of the detection.

[0004] During use, the above-mentioned inspection fixture for checking the contour of the turbine shell can adjust the height positions of multiple support wheels to adapt to turbine shells of different sizes, but it requires multiple power sources to drive it, which increases energy consumption and increases costs. In addition, it uses a universal ball to contact the surface of the turbine shell and cooperate with the extrusion plate to clamp and prevent the turbine shell from deviating. However, the force applied to the surface of the turbine shell through the universal ball is concentrated at one point. If the force is small, the clamping effect on the turbine shell is poor. If the force applied to the turbine shell is large, the surface of the turbine shell is easily dented and damaged, and its practicality is relatively poor. Utility Model Content

The outer wall of the torsion bar 28 is symmetrically provided with a fixing rod 29, and the relatively outer end of the fixing rod 29 is movably connected with an insertion rod 31 through a connecting rod 30. A connecting block 32 is symmetrically provided on one side of the slider 3 20, and one end of the connecting block 32 is inserted into a slot provided in the side wall of the slider 3 20, and one end of the connecting block 32 is fixedly connected to the contour detector 21, and the relatively outer end of the insertion rod 31 passes through the through groove provided in the side wall of the connecting block 32.

The upper end of the torsion bar 28 is connected with a twist handle above the slider 3 20. The contour detector 21 can be conveniently disassembled through the connecting assembly for maintenance and repair, which is convenient to use. In this example, the slider 1 6 is threadedly connected to the screw rod 5, and the slider 1 6 is rotatably connected to the hydraulic cylinder 7 through a bearing. The slider 2 16 is threadedly connected to the bidirectional screw rod 15, so as to connect the hydraulic cylinder 7 and the slider 1 6 without affecting the rotation of the hydraulic cylinder 7.

In this example, the torsion bar 28 is rotatably connected to the slider 3 20 through a bearing, and the two fixed rods 29 are arranged in a circumferentially equidistant array.

[0025] The working principle of the utility model is as follows: when in use, the height positions of the extrusion rod 17 and the extrusion disk 8 are adjusted according to the size of the turbine shell to be detected, and the connected screw rod 5 is driven to rotate by starting the motor 2 13, and the sprocket 3 18 and the chain 2 19 drive the other screw rod 5 to rotate synchronously, so as to realize the synchronous driving of the two sliders 1 6 to move upward or downward along the slide bar 4, and then drive the extrusion rod 17 and the extrusion disk 8 to move up and down synchronously, and stop the motor 2 13 after moving them to the appropriate position, and then twist the handle to drive the bidirectional screw rod 15 to rotate, and synchronously drive the two sliders 2 16 to drive the extrusion rod 17 to move relatively outward or inward. Then, the hydraulic cylinder 7 is started to push the extrusion plate 8 and the adjustment frame 14, so that the extrusion plate 8 and the rubber block at one end of the extrusion rod 17 clamp and fix the turbine shell, limit it, and avoid deviation during detection. Then, the motor 3 22 and the motor 4 27 can be used to drive the screw rod 2 35 and the screw rod 1 25 to adjust the height and front-to-back position of the contour detector 21, so as to facilitate the detection of the contour of the turbine shell. At the same time, the motor 1 9 is started to drive the sprocket 10 to rotate, and the sprocket 2 11 drives the chain 12 to rotate, so that the chain 12 drives the hydraulic cylinder 7 connected thereto to rotate, thereby driving the extrusion plate 8.

While the torsion bar 28 rotates, the baffle plate 33 is driven to twist the torsion spring 34, and then the contour detector 21 can be pulled to the side away from the slider 320 to drive the connecting block 32 to move out of the insertion rod. The groove is formed by the screw thread of the torsion spring 34, thereby completing the disassembly of the contour detector 21 for its inspection or maintenance. During installation, the above disassembly steps are repeated to move the connecting block 32 between the two slots, and then the contour detector 21 is installed on the inner side of the slider 3 20, so that the connecting block 32 is inserted into the corresponding slot, and the force applied to the torsion handle is released, so that the baffle 33 is reset and rotated under the torsion of the torsion spring 34, thereby driving the torsion bar 28 to drive the fixing rod 29 to reset and rotate, and then driving the connecting rod 30 to push the insertion rod 31 to be inserted into the through groove, completing the restriction and fixation of the connecting block 32, thereby completing the installation and fixation of the contour detector 21, which is convenient to use and more practical.
