[0002] In industrial production, plastic workpiece is widely used in various fields, and its quality and performance directly affect the overall quality and service life of the product, among which, the side wall stiffness of plastic workpiece is one of the important indicators to measure its quality, and accurate detection is crucial.

[0003] At present, in actual detection process, the corresponding plastic workpiece 1 of the present application, as shown in Figure 1 Two pairs of vertical plates 11 are arranged at intervals in X and Y directions, and each vertical plate 11 is connected to the adjacent vertical plate 11 at its side edge. When detecting the stiffness of the side plate 11 of the above plastic workpiece 1, place the plastic workpiece 1 at the preset position, use a simple pressure device to press the side wall, and measure the deformation of the side plate 11 of the plastic workpiece 1 to judge its stiffness. However, during the detection process, on the one hand, the simple fixing tool is difficult to accurately position the plastic workpiece 1, resulting in deviation of the position of the plastic workpiece 1 during each detection, affecting the accuracy of the detection result; on the other hand, the pressure device is difficult to apply appropriate detection force, which is easy to cause damage to the side plate 11. Therefore, a plastic workpiece detection tool is needed to solve the above problems. UTILITY MODEL CONTENT

The positioning assembly stably positions the plastic workpiece at the preset position on the base plate, so as to ensure that the plastic workpiece does not move during the entire detection process, and the accuracy of detection is ensured. The top head floatingly arranged in the top contact assembly can not only apply stable detection pressure when contacting the vertical plate to be detected, but also can avoid damage to the plastic workpiece caused by excessive detection pressure, and ensure the uniformity of the detection force.

[0033] Based on the above structure, the principle of the plastic workpiece detection tool is: first, place the plastic workpiece 1 on the base plate 8, accurately position it through the positioning assembly 2 to ensure that the position of the plastic workpiece 1 is consistent during each detection, at this time, the measurement sensor 41 records the position parameters of the vertical plate 11 to be measured; then, according to the position of the vertical plate 11 to be measured, move the adjusting dynamic plate 31, so that the top head 32 is in contact with the vertical plate 11 to be measured with a preset pressure, at this time, the vertical plate 11 to be measured deforms in the X direction, and since the top head 32 is elastically floating, it can avoid damaging the plastic workpiece 1 due to excessive pressure of the top head 32; then, the position parameters of the deformed vertical plate 11 are recorded again through the measurement sensor 41, and the rigidity of the vertical plate 11 is obtained by comparing the before and after analysis of the vertical plate 11 to be measured; the positioning assembly 2 stably positions the plastic workpiece 1 at the preset position on the base plate 8, ensuring that the plastic workpiece 1 does not move during the entire detection process, ensuring the accuracy of the detection; the floating top head 32 in the top contact assembly 3 can apply stable detection pressure when contacting the vertical plate 11 to be measured, and can avoid damaging the plastic workpiece 1 due to excessive detection pressure, ensuring the uniformity of the detection force.

[0034] In the embodiment, the positioning assembly 2 includes: an X-direction positioning part 21, a Y-direction positioning part 22, and a limiting part 23, the X-direction positioning part 21 and the Y-direction positioning part 22 are detachably installed on the base plate 8, the side surfaces of the X-direction positioning part 21 and the Y-direction positioning part 22 are respectively fitted with the corresponding vertical plate 11 in the X and Y directions, and the limiting part 23 is movably adjusted and arranged on the base plate 8, and the limiting part 23 is used for locking and limiting the plastic workpiece 1 on the base plate 8 in the X and Y directions. The X-direction positioning part 21 and the Y-direction positioning part 22 can respectively position the plastic workpiece 1 in the X and Y directions, and through positioning in the two directions, the plastic workpiece 1 is accurately positioned on the base plate 8; the X-direction positioning part 21 and the Y-direction positioning part 22 are detachably installed on the base plate 8, which makes the positioning assembly 2 flexible adjustment according to the size and shape of different plastic workpieces 1, improves the versatility and applicability of the detection tool. The X-direction positioning part 21 and the Y-direction positioning part 22 are detachably installed on the base plate 8 through screws.

[0035] In the embodiment, the base plate 8 is provided with a through guide groove 10 extending in the X direction, the guide groove 10 is provided with a locking component 5, the locking component 5 can be adjusted in the extension direction of the guide groove 10, the limiting component 23 comprises: a base 231, the locking component 5 is used for locking the position of the base 231 on the base plate 8, when the locking component 5 locks the base 231 and the base plate 8, the locking component 5 axially locks the base 231 and the base plate 8, so that the base 231 and the base plate 8 are axially closely fitted. The limiting component 23 is used for stably positioning the plastic workpiece 1 on the base plate 8, ensuring the stability of the position of the plastic workpiece 1 in the detection process, and improving the reliability of the detection result; the locking component 5 can be adjusted in the extension direction of the guide groove 10, so that the position of the limiting component 23 can be flexibly adjusted according to the actual needs of the plastic workpiece 1, so as to adapt to various detection situations, and enhance the universality and adaptability of the detection tool. The locking component 5 adopts a screw and a nut.

[0036] As shown in Figure 4 、 5 In the embodiment, the limiting component 23 further comprises: a top pressing block 232, a top rod 233, a connecting rod 234, a handle 235, and a mounting seat 236. The mounting seat 236 is detachably mounted on the base 231 and can be movably adjusted in the Z direction. The top rod 233 is slidingly mounted on the mounting seat 236. The top pressing block 232 is mounted on the end of the top rod 233 away from the mounting seat 236. The connecting rod 234 and the handle 235 are arranged on the same side of the top rod 233. The handle 235 is pivotally connected with the mounting seat 236. The two ends of the connecting rod 234 are respectively pivotally connected with the top rod 233 and the handle 235. When the limiting component 23 is in the locked state, the pivots between the top rod 233 and the connecting rod 234, the connecting rod 234 and the handle 235, and the handle 235 and the mounting seat 236 are collinear and parallel. The top pressing block 232 presses the corner of the plastic workpiece 1 away from the X-direction positioning part 21 and the Y-direction positioning part 22. The mounting seat 236 is detachably mounted on the base 231 and can be movably adjusted in the Z direction, so that the height of the top pressing block 232 can be flexibly adjusted according to the thickness of the plastic workpiece 1 or different detection needs, ensuring that the top pressing block 232 can accurately press the plastic workpiece 1 at the appropriate position, and enhancing the universality of the detection tool for different workpieces.

[0037] When the plastic workpiece 1 needs to be limited and locked, the operator holds the handle 235 and applies an external force to make the handle 235 rotate around the pivot of the mounting seat 236. The rotation of the handle 235 drives the connecting rod 234 connected with the handle 235 to move. The connecting rod 234 changes the position of one end with the rotation of the handle 235, and the other end pushes the jack 233 to slide on the mounting seat 236. Since the connecting rod 234 is pivotally connected with the jack 233 and the handle 235 at both ends, the jack 233 moves towards the plastic workpiece 1. When the pressing block 232 contacts the corner of the plastic workpiece 1, further pushing the jack 233 will make the pressing block 232 apply a pressing force to the plastic workpiece 1, thereby limiting the movement of the plastic workpiece 1. When the pivots between the jack 233 and the connecting rod 234, the connecting rod 234 and the handle 235, and the handle 235 and the mounting seat 236 are collinear, a stable mechanical structure is formed, thereby realizing reliable limiting and fixing of the plastic workpiece 1.

[0038] When the plastic workpiece 1 needs to be released from the limiting and locking, the operator reverses the handle 235 and applies a force in the opposite direction of the pressing operation to make the handle 235 start to rotate reversely around the pivot of the mounting seat 236. With the reverse rotation of the handle 235, one end of the connecting rod 234 moves with the handle 235, and the other end pulls the jack 233 to slide on the mounting seat 236 away from the plastic workpiece 1. The retreat of the jack 233 makes the pressing block 232 installed at one end gradually move away from the corner of the plastic workpiece 1. When the pressing block 232 is completely out of contact with the plastic workpiece 1, the pressing is released, and the locking of the plastic workpiece 1 is released.

When the pressing block 232 presses on the plastic workpiece 1, the pair of side surfaces respectively abut the pair of vertical plates 11 perpendicular to the plastic workpiece 1. The pair of mutually perpendicular side surfaces on the pressing block 232 can accurately fit the pair of vertical plates 11 perpendicular to the plastic workpiece 1, and the X-direction positioning part 21 and the Y-direction positioning part 22 respectively limit the plastic workpiece 1 in the X and Y directions, ensuring that the plastic workpiece 1 does not shift during detection and ensuring the accuracy of the detection data.

The first linear driving device 33 cooperates with the first track 34, the driving end of the first linear driving device 33 being connected with the movable plate 31, so that the movable plate 31 can be controlled to move in the X direction. When detecting plastic workpieces 1 of different sizes, the movable plate 31 can be accurately moved to the required position by the first linear driving device 33, so as to ensure that the top head 32 can accurately align with the to-be-detected vertical plate 11, and the flexibility and accuracy of detection are improved. The top head 32 is detachably mounted on the slide plate 36. When it is necessary to detect plastic workpieces 1 of different specifications, the top head 32 can be replaced to meet different detection requirements, and the versatility of the detection tooling is improved. In the moving process of the movable plate 31, the top head 32 on the slide plate 36 is brought into contact with the to-be-detected vertical plate 11. When the pressing force exceeds the design threshold value, the slide plate 36 drives the top head 32 to move along the second track 35 away from the plastic workpiece 1. The elastic member 37 is used to make the top head 32 always contact the to-be-detected vertical plate 11 during the movement of the slide plate 36 away from the plastic workpiece 1.
