CONCRETE IMPLEMENTING METHOD

[0025] The utility model will be further described in connection with the drawings and embodiments:

[0026] Embodiment one: refer to Figures 1-3 Shown, a kind of plastic gear assembly detection device, including bottom plate 1, product positioning frame 2 and detection mechanism on the bottom plate 1 are installed, the bottom of the product positioning frame 2 is installed on the bottom plate 1 by support 3, the top of the product positioning frame 2 is equipped with product containing groove 4.

[0027] The right side of the product positioning frame 2 is provided with a support plate 5 extending to the right, and the top of the support plate 5 is provided with a detection through slot 6 in communication with the bottom surface of the support plate 5;

[0028] A vertical air cylinder 7 is arranged on the bottom plate 1 below the product positioning frame 2, and an output shaft at the top of the vertical air cylinder 7 is provided with a detection member;

[0029] The detection member includes a connecting member 8 and at least one detection rod 9 vertically movably arranged on the connecting member 8, and the detection rod 9 is arranged directly below the detection through slot 6; in this embodiment, three detection rods are arranged, which can simultaneously detect three positions and have higher detection accuracy.

[0030] A through hole 9 is arranged on the connecting member 8, and the middle part of the detection rod 10 is movably connected with the through hole 9; the top of the detection rod 10 is provided with an annular head 11, and a nut 12 is screwed below the detection rod 10; the annular head 11 and the nut 12 are arranged above and below the through hole 9, respectively; a spring 13 is further sleeved on the detection rod 10, and the two ends of the spring 13 are respectively abutted on the bottom surface of the annular head 11 and the top surface of the connecting member 8.

[0031] In this embodiment, a scale is arranged on the outer surface of the detection rod, and the scale is arranged below the connecting member; when detecting the product, the product is placed in the product containing groove, then the output shaft of the vertical air cylinder is extended to drive the detection rod to move upward, and the detection rod moves upward due to the existence of the spring; in the initial state, the spring pushes the detection rod to move upward, so that the top surface of the nut abuts against the bottom surface of the connecting member; when the connecting member moves upward driven by the vertical air cylinder, the detection rod moves upward synchronously, so that the detection rod penetrates into the detection through slot and contacts the bottom surface of the position of the product to be detected (the annular head top surface contacts the product); at this time, the connecting member continues to move upward until the output shaft of the vertical air cylinder is extended to the position and no longer moves; in this process, the detection rod no longer continues to move upward, the connecting member moves upward relative to the detection rod to compress the spring, and the bottom of the connecting rod moves downward relative to the connecting member. After the connecting member is moved upward to the position driven by the vertical air cylinder, the detection personnel can check the position of the detection rod relative to the connecting member, mainly the relative position between the scale and the bottom surface of the connecting member, so as to know whether the product detection position is qualified. After the detection is completed, the output shaft of the vertical air cylinder is retracted, and the operator takes away the product in the product containing groove; the qualified product is placed in the qualified product placement position, and the unqualified product is placed in the special storage position for defective products. In this way, the detection efficiency can be effectively improved, each product can be quickly detected, and the qualified rate of the product can be ensured.

[0034] In the embodiment, if the product is placed in the product accommodating groove and the detection position is just against the support plate, in the state that the output shaft of the vertical cylinder extends, the top of the detection rod is in the detection channel and its top surface is against the bottom surface of the product detection position. If there is a certain space between the bottom surface of the product and the support plate, the detection rod will pass through the detection channel and be arranged above the top surface of the support plate. If the bottom surface of the product is against the support plate and the detection position is above the support plate, the top of the detection rod will also pass through the detection channel and be arranged above the top surface of the support plate. After the detection is completed, the output shaft of the vertical cylinder retracts to drive the detection rod to move downward, so that the top of the detection rod moves below the bottom surface of the support plate. During the downward movement of the connecting rod driven by the vertical cylinder, in the initial state, the spring will push the detection rod to move upward relative to the connecting piece until the nut is against the bottom surface of the connecting piece, and then the output shaft of the vertical cylinder retracts to drive the detection rod to move downward and out of the detection channel.

[0035] In the embodiment, since the connecting piece and the detection rod driven by the vertical cylinder move upward at a relatively fast speed, the spring is arranged to make the connecting piece drive the detection rod to move upward and contact the product detection end, so that the detection rod and the product are in flexible contact, preventing damage to the product.

[0036] The bottom plate 1 is further provided with a laser displacement sensor 14 and an electric cylinder 15.

[0037] In this embodiment, in order to reduce the labor intensity of manual observation detection and prevent the deviation of manual detection, a laser displacement sensor is arranged, and during the process of moving the detection rod upward and contacting the product and detecting, the electric cylinder drives the laser displacement sensor to move to the lower side of the detection rod, so as to detect the distance between the bottom surface of the connecting piece and the bottom surface of the detection rod, and realize the rapid automation and high-precision detection of the product. After the detection is completed, in order to prevent the detection rod from moving downward and damaging the laser displacement sensor, or interfering with the downward movement of the detection rod, the occupation of the height space is also reduced, so that the laser displacement sensor can detect the distance between the bottom surface of the connecting piece and the bottom surface of the detection rod at a closer distance, and the detection precision is ensured. Therefore, the electric cylinder is used to drive the movement of the laser displacement sensor, so as to reduce the occupation of the height space, and also ensure the detection precision.
