[0002] In industrial production fields such as machining and mold manufacturing, conformal inspection is a crucial step in ensuring product quality. By using conformal inspection equipment, it is possible to quickly and accurately determine whether the contour and dimensions of a workpiece meet the requirements of the design drawings.

[0003] In traditional production lines, contour inspection of specific workpieces typically involves the design and use of dedicated inspection fixtures. These fixtures are designed with measurement points and positioning references fixed according to the workpiece drawings. They are compact in structure, highly accurate in measurement, and can achieve high efficiency for large-volume, single-product production tasks.

[0004] However, as modern manufacturing moves towards higher-variety, smaller-batch, and customized production, the limitations of the aforementioned specialized inspection fixtures are becoming increasingly apparent. Each time a new workpiece specification is changed, one or even multiple sets of matching specialized fixtures need to be replaced. This not only significantly increases production auxiliary time and warehousing costs but also reduces the overall flexibility of the production line.

[0005] However, existing adjustable testing instruments still have structural shortcomings. Their adjustment mechanisms are often quite complex, requiring tedious disassembly and reassembly with the help of various tools. The adjustment process is time-consuming and laborious, and it is difficult to guarantee the repeatability of positioning accuracy after each adjustment, which directly affects production efficiency and the reliability of test results.

[0006] Therefore, this utility model proposes a contour detection device to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a contour detection device, which aims to improve the problems of fixed structure, poor versatility, cumbersome and laborious adjustment process and low positioning accuracy of the existing contour detection device.

[0011] Preferably, it also includes an adjustment component, which consists of the sliding seat, the sliding groove, the screw hole, and the hand-tightening screw.

[0012] Preferably, the sliding seat has a through hole for the hand-tightening screw to pass through, and the head of the hand-tightening screw presses against the top surface of the sliding seat when tightened.

[0013] Preferably, the operating table is provided with a plurality of screw holes arranged along the length direction of the slide groove.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 The present invention provides an embodiment of a contour detection instrument, which aims to solve the problems of existing contour detection instruments having a fixed structure and narrow applicability, and being difficult to quickly adjust to adapt to the detection of workpieces of different sizes.

[0024] The contour measuring instrument includes a support frame 1 and an operating platform 2 fixedly connected to the top of the support frame 1. The support frame 1 serves as the mounting base for the entire device, providing stable support. The operating platform 2 provides a working platform for measuring the workpiece. A fixing plate 3 is fixedly connected to the top of the operating platform 2, and at least two fixing blocks 4 are spaced apart on the top of the operating platform 2. A sliding groove 602 is provided on the top of the operating platform 2, and a sliding seat 601 is fixedly connected to the bottom of each fixing block 4. The sliding seat 601 is slidably fitted into the sliding groove 602. A screw hole 603 is provided on the operating platform 2 along the edge of the sliding groove 602, and a hand-tightening screw 604 is inserted into each sliding seat 601. The hand-tightening screw 604 is connected to the corresponding screw hole 603. The screw hole 603 is threaded to lock the fixing block 4 onto the operating table 2. At least one of the fixing blocks 4 is provided with a measuring component 5 inside. The measuring component 5 includes a measuring plate 501 and a sliding rod 502 that slides through the fixing block 4. The measuring plate 501 is fixedly connected to one end of the sliding rod 502. A limit ring 503 is fixedly connected to the outer periphery of the sliding rod 502. A spring 504 is provided inside the fixing block 4. The spring 504 is sleeved on the sliding rod 502, and the two ends of the spring 504 abut against the inner wall of the fixing block 4 and the limit ring 503, respectively. A sensor 505 is also fixedly provided inside the fixing block 4. The sensor 505 is arranged parallel to the sliding path of the sliding rod 502.

[0025] The locking structure is achieved by the adjustment component 6. The technical solution is to open the slide groove 602 and screw hole 603 on the operating table 2, and set the sliding seat 601 and hand screw 604 at the bottom of the fixing block 4 to cooperate with it, thus forming a convenient and reliable spacing adjustment method.

[0026] The top surface of the operating table 2 is provided with a slide groove 602 extending in a predetermined direction, and a plurality of screw holes 603 arranged along the length of the slide groove 602 are provided on the operating table 2. The slide groove 602 provides a precise guide path for the movement of the fixed block 4, while the plurality of screw holes 603 provide a plurality of discrete, repeatable locking points for the fixed block 4.

[0027] Meanwhile, each fixed block 4 is fixedly connected to a sliding seat 601 at its bottom. The shape and size of the sliding seat 601 are adapted to the slide groove 602. The sliding seat 601 has a through hole for the hand screw 604 to pass through. In the assembled state, the sliding seat 601 at the bottom of the fixed block 4 slides into the slide groove 602 at the top of the operating table 2. After the hand screw 604 passes through the through hole on the sliding seat 601, it forms a threaded connection with a screw hole 603 on the operating table 2. When the hand screw 604 is tightened, it presses against the top surface of the sliding seat 601, thereby locking the fixed block 4 firmly in the current position through friction. This combination structure of slide groove guidance and multi-point screw locking ensures that the fixed block 4 moves smoothly during adjustment and has extremely high stability and positional accuracy after positioning.

[0028] To achieve accurate measurement of workpiece dimensional deviations, the measuring component 5 inside the fixing block 4 has a specific internal structure, please refer to... Figure 3 The measuring plate 501 is fixedly connected to the end of the sliding rod 502 away from the spring 504, and a portion of the surface of the measuring plate 501 is exposed outside the fixed block 4 for direct contact with the workpiece to be measured and to transmit displacement. The sliding process of the sliding rod 502 inside the fixed block 4 is elastically constrained by the spring 504, thereby achieving automatic reset after measurement. The sensor 505 is preferably a non-contact sensor, such as a Hall sensor or a photoelectric sensor. The sensor 505 is fixed inside the fixed block 4 and maintains a fixed positional relationship with the movement of the sliding rod 502, accurately sensing the minute displacement of the sliding rod 502 without physical contact.

[0029] The fixing plate 3 and the at least two fixing blocks 4 are arranged opposite to each other in the measurement space. The fixing plate 3 is used to reliably fix one end of the workpiece or a reference surface during measurement, while the two fixing blocks 4 position and measure the contour of the workpiece from different directions. Together, the three constitute a stable and reliable measurement reference system.

[0030] Working principle: When adjusting the spacing of the fixing block 4, the thread of the hand screw 604 is disengaged from the screw hole 603 on the operating table 2 by tightening the hand screw 604. At this time, the locking of the fixing block 4 is released, and the operator can pull the fixing block 4. The sliding seat 601 at the bottom of the fixing block 4 will slide along the slide groove 602 at the top of the operating table 2. After adjusting to a position suitable for the current workpiece size, the hand screw 604 is aligned with the screw hole 603 corresponding to the position and tightened. The head of the hand screw 604 presses against the sliding seat 601, thereby firmly locking the fixing block 4 back into the new position.

[0031] When measuring a workpiece, the workpiece is placed in a measuring space consisting of two fixed blocks 4 and a fixed plate 3. The contour of the workpiece to be measured is in contact with the measuring plate 501. If there is a deviation in the workpiece size and it pushes the measuring plate 501, the measuring plate 501 will drive the sliding rod 502 to slide inside the fixed block 4. The movement of the sliding rod 502 causes the limiting ring 503 to compress the spring 504. At the same time, the sensor 505 fixed inside the fixed block 4 senses the movement distance of the sliding rod 502 in real time and outputs the distance signal, thereby obtaining the specific deviation parameters of the workpiece size. When the workpiece is removed, the compressed spring 504 recovers its deformation and pushes the limiting ring 503 and the sliding rod 502, so that the measuring plate 501 automatically resets.
