[0001] The utility model relates to the technical field of workpiece production, in particular to a workpiece deformation inspection tool. Background Art

[0002] A workpiece refers to the object to be processed during machining. It can be a single part or a combination of several parts fixed together. There are various ways to process a workpiece, including turning, milling, planing, grinding, casting, forging, etc. The processing procedures of the workpiece also change with the changes in the processing methods. In the production process of workpieces, it is often necessary to detect the deformation of the processed workpiece to determine whether it meets the requirements of the process. In actual testing, staff often use a measuring ruler to measure various parts of the workpiece and compare the measurement results with the standard, that is, manually confirm the degree of deformation of the workpiece.

[0003] However, the existing measurement methods have a high cost for manpower consumption, and after a long period of measurement, fatigue and other conditions may occur, which may lead to inattention. In addition, when measuring manually, different sizes of the workpiece need to be measured separately to determine whether the workpiece is qualified, which is more troublesome.

DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] Please refer to Figure 1-5The utility model discloses a workpiece deformation inspection tool, comprising a detection platform 1 and a workpiece body 11. The detection platform 1 is the main structure of the inspection tool, which is used to install other structures. The workpiece body 11 is the workpiece to be inspected, that is, the workpiece body 11 is placed at the corner of the detection platform 1 for subsequent fixed inspection. A fixing member 2 is arranged on the detection platform 1, and the fixing member 2 is used to fix the workpiece. A threaded rod 22 is arranged on the outside of the fixing member 2, and a threaded opening 13 is arranged on the outside of the detection platform 1. The threaded rod 22 is threadedly connected to the threaded opening 13. A rotating opening 21 is arranged on the rear side of the fixing member 2, and a rotating bolt 23 is arranged on the top of the threaded opening 13. The swivel bolt 23 is connected to the swivel port 21, and the swivel bolt 23 rotates on the swivel port 21. A slider 24 is provided at the bottom of the fixing member 2, and a slide rail 14 is provided on the inner side of the bottom of the threaded port 13. The threaded rod 22 rotates on the threaded port 13, that is, the threaded rod 22 is adjusted on the threaded port 13, and the swivel port 21 is connected to the swivel bolt 23 and rotates on the swivel port 21, and the slider 24 at the bottom slides on the slide rail 14, that is, the fixing member 2 is driven to be adjusted, so that the workpiece is fixed by the fixing member 2, and a scale line 12 is provided on the detection table 1, and the width of the workpiece is observed through the scale line 12, that is, its width is detected.

[0025] A detection member 3 is arranged above the detection table 1. The detection member 3 is used to detect the height of the workpiece. A first electric push rod 31 is arranged on the top of the detection member 3, that is, the detection member 3 is driven to extend and retract by the first electric push rod 31. The extension distance parameter is adjusted by workpieces of different thicknesses. The extension distance is fixed. A slide groove 32 is arranged at the bottom of the detection member 3. A sliding member 4 is arranged inside the slide groove 32. The sliding member 4 slides in the slide groove 32. That is, when the bottom of the sliding member 4 just contacts the workpiece and does not slide in the slide groove 32, the thickness of the workpiece is just right. A first spring 43 is arranged inside the sliding member 4. A mounting spring 43 is arranged on the top of the first spring 43. The mounting ring 34 is fixed on the top of the slide groove 32, and a sensing head 42 is arranged at the bottom of the sliding member 4. When the thickness of the workpiece is not enough, the sensing head 42 cannot sense the workpiece, that is, a problem is detected. A first contact head 41 is arranged on the inner side of the first spring 43, and a first sensing member 33 is arranged on the inner side of the top of the slide groove 32. When the workpiece is deformed and bulged, that is, the first electric push rod 31 pushes the sliding member 4 to move downward, the sliding member 4 contacts the workpiece and continues to move downward, that is, it expands and contracts on the slide groove 32, thereby causing the first spring 43 to contract, and the first contact head 41 contacts the first sensing member 33, thereby determining that there is a problem with the inspection.

[0026] A detection block 5 and a second electric push rod 52 are arranged on one side of the detection table 1, that is, the length of the workpiece is detected by the detection block 5, and the second electric push rod 52 drives the detection block 5 to extend and retract, and is made of the same material as the first electric push rod 31. A connecting block 55 is arranged on the top of the second electric push rod 52, and a second spring 51 is arranged on the connecting block 55. The second spring 51 is connected to the detection block 5, and a second contact head 53 is arranged on the inner side of the detection block 5, and a second induction table 54 is arranged on the inner side of the connecting block 55. That is, when the second electric push rod 52 pushes the detection block 5 to just contact the workpiece, the length of the workpiece is just right, and if it is not long enough, it cannot contact. When it is too long, it will cause the spring to contract, that is, the second contact head 53 contacts the second induction table 54, that is, the detection fails.

[0027] The working principle of the utility model is as follows: the workpiece is placed at the corner of the detection table 1, the threaded rod 22 is rotated on the threaded port 13, the rotating port 21 is connected by the rotating bolt 23 and rotated on the rotating port 21, and the slider 24 at the bottom slides on the slide rail 14, that is, the fixing member 2 is driven to adjust, so as to fix the workpiece, and the width of the workpiece is observed through the scale line 12, that is, the width is detected, and the detection member 3 is driven to extend and retract through the first electric push rod 31. When the bottom of the sliding member 4 just contacts the workpiece and does not slide in the slide groove 32, the thickness of the workpiece is just right. When the thickness of the workpiece is not enough, The sensing head 42 cannot sense the workpiece, i.e., a problem is detected. When the workpiece is deformed and bulged, the sliding member 4 continues to move downward after contacting the workpiece, i.e., it expands and contracts on the slide slot 32, thereby causing the first spring 43 to contract, and the first contact head 41 contacts the first sensing member 33, thereby determining that there is a problem with the inspection. The second electric push rod 52 drives the detection block 5 to expand and contract, and the expansion and contraction distance is fixed. When the detection block 5 just contacts the workpiece, the length of the workpiece is just right. If it is not long enough, it cannot contact. When it is too long, it will cause the spring to contract, i.e., the second contact head 53 contacts the second sensing table 54, i.e., the inspection fails.

[0028] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
