Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece detection, and in particular relates to a tool for detecting the height and position of a workpiece. Background Art

[0002] The machining process of precision workpieces requires multiple inspections. In the production workshop, inspectors first inspect the workpiece's appearance size and inner hole position. In mass production, inspectors generally conduct random inspections, and products need to be inspected one by one before packaging. Currently, commonly used inspection workpieces include three-coordinate measuring machines, vernier calipers, outside micrometers, and inside micrometers.

[0003] At present, when inspecting the appearance size and inner hole position of the workpiece, it is necessary to perform inspections at different workstations. For example, when inspecting the inner hole position of the workpiece, the workpiece needs to be transferred to a three-coordinate measuring machine for inspection, while when inspecting the appearance size of the workpiece, the workpiece needs to be transferred to other workstations for inspection. The inspection efficiency is low and is only suitable for random inspections, which cannot meet production needs at all. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] A typical implementation of the present utility model is as follows Figure 1 As shown, a workpiece height and position detection tool comprises a detection table 1, and support columns 2 are arranged around the bottom of the detection table 1. The detection table 1 is fixed on the workbench through the support columns 2. The height of the workbench is adapted to the height of the staff, so that the staff can easily take the workpiece 3 for detection. Figure 2As shown, a through hole 4 is opened in the middle of the testing platform 1, and a cylinder 5 is fixedly connected to the bottom surface of the testing platform 1. The fixed end of the cylinder 5 is fixedly connected to the bottom surface of the testing platform 1 through a fixed block, so that the cylinder 5 and the testing platform 1 are vertically arranged, and the telescopic rod of the cylinder 5 passes through the through hole 4 and extends to the top of the testing platform 1. A pressure block 6 is arranged on the top of the telescopic rod of the cylinder 5, and a locking nut 7 is threadedly connected to the telescopic rod of the cylinder 5. The pressure block 6 is fixedly connected to the telescopic rod of the cylinder 5 through the locking nut 7.

[0025] Thus, the cylinder 5 drives the pressing block 6 to move up and down, and the pressing block 6 is used to fix the workpiece 3 on the inspection platform 1.

[0026] The workpiece 3 in this embodiment is a circular ring structure. Figure 3 As shown, a plurality of connecting plates 8 are evenly arranged on the circumference thereof. The plurality of connecting plates 8 have the same length and all extend toward the axial direction of the workpiece 3. Detection holes 9 are opened on the plurality of connecting plates 8, and the position of the detection holes 9 and the height of the workpiece 3 need to be detected.

[0027] A plurality of detection rods 10 are arranged on the upper surface of the detection platform 1, and the plurality of detection rods 10 are arranged corresponding to the plurality of detection holes 9. The detection rods 10 are round rods and are vertically fixed on the upper surface of the detection platform 1. The diameter of the detection rods 10 is the same as the diameter of the detection holes 9. When the detection holes 9 are sleeved on the outside of the detection rods 10, no shaking will occur, thereby ensuring the accuracy of the detection.

[0028] like Figure 4 As shown, a plurality of limiting holes 11 are provided on the pressing block 6, and the plurality of limiting holes 11 are arranged corresponding to the plurality of detecting rods 10. The diameter of the limiting holes 11 is larger than the diameter of the detecting rods 10, so that when the pressing block 6 is lifted or lowered, the detecting rods 10 will not interfere with the lifting or lowering of the pressing block 6.

[0029] An annular groove 12 is provided on the upper surface of the detection platform 1 , and the annular groove 12 is arranged corresponding to the outer circle 13 of the workpiece, so as to avoid interference between the detection platform 1 and the workpiece 3 and affect the accuracy of detection.

[0030] How it works

[0031] When in use, first use the cylinder to lift the pressing block, place the workpiece between the pressing block and the inspection table, and the multiple inspection holes on the workpiece are all set on the inspection rod. Since the diameter of the inspection rod is the same as the diameter of the inspection hole, if the inspection hole cannot be set on the inspection rod, it means that the position of the inspection hole of this workpiece is unqualified;

[0032] For workpieces that pass the position detection, continue to detect the workpiece height. Control the cylinder to drive the pressure block to descend, use the pressure block to press the workpiece onto the detection table, and use a feeler gauge to measure the distance between the outer cylindrical end face of the workpiece and the detection table, that is, the height of the outer cylindrical end face of the workpiece. When the distance between the outer cylindrical end face of the workpiece and the detection table is consistent, it means that the workpiece is qualified.

[0033] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
