[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] Reference Figure 1-5 As shown, a shrinkage shaping and inspection device for metal products includes an operating cabinet 1, a testing mechanism arranged on one side of the top surface of the operating cabinet 1, a hole enlarging shaping mechanism arranged on the rear side of the middle of the top surface of the operating cabinet 1, and a manipulator 14 arranged on the front side of the middle of the top surface of the operating cabinet 1;

[0029] By setting up the manipulator 14, the hole expansion and shaping mechanism and the testing mechanism, after the inner hole sawing of the metal product is completed, the manipulator 14 can place the product on the hole expansion and shaping mechanism and the testing mechanism in turn, replacing manual work to expand the hole and perform hole mouth quality inspection on the metal product, effectively eliminating misjudgment and improving work efficiency.

[0030] Specifically, refer to Figure 1 and Figure 2 As shown, it is worth noting that the hole expansion and shaping mechanism includes a base 3 fixed on the top surface of the operating cabinet 1, a vertical rod 4 vertically fixed on the base 3, and a mounting seat 5 fastened and sleeved on the rod body of the vertical rod 4, a first cylinder 6 is installed on the mounting seat 5, and a telescopic rod of the first cylinder 6 passes through the mounting seat 5 and is fixed with a punch head 7;

[0031] The metal product is placed on the base 3 using the manipulator 14 so that the opening of the metal product corresponds to the punch head 7. The first cylinder 6 is then turned on, and the telescopic rod of the first cylinder 6 drives the punch head 7 downward, so that the punch head 7 is inserted into the shrinkage hole of the metal product, thereby shaping the aperture of the product by extrusion.

[0032] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that the test mechanism includes a support seat 8 fixed on the top surface of the operating cabinet 1 in an inverted L shape and a second cylinder 10 installed on the top surface of the support seat 8. The telescopic rod of the second cylinder 10 penetrates the inner side of the support seat 8 and is fixed with a movable seat 9. A pass-stop step needle gauge 11 is arranged on the side of the movable seat 9.

[0033] After the hole expansion and shaping mechanism is used to complete the shaping of the aperture of the product, the manipulator 14 is used again to move the product under the pass-stop step needle gauge 11, so that the hole opening of the metal product corresponds to the pass-stop step needle gauge 11, and then the second cylinder 10 is turned on, so that the movable seat 9 is pushed by the telescopic rod of the second cylinder 10, and moves down with the pass-stop step needle gauge 11 to be inserted into the hole opening of the metal product. If the pass-stop step needle gauge 11 cannot be inserted into the interior of the product through the shrinkage hole, the pass-stop step needle gauge 11 leaks out of the product for a long length, and the product is determined to be not up to standard for hole expansion, and the product is unqualified. On the contrary, if the pass-stop step needle gauge 11 is inserted into the interior of the product through the hole opening, the pass-stop step needle gauge 11 leaks out of the product for a long length, and the product is determined to be up to standard for hole expansion, and the product is qualified.

[0034] Further, refer to Figure 2 As shown, it is worth noting that a distance sensor 12 is installed on the top of the support seat 8, the detection end of the distance sensor 12 is directly opposite to the top of the pass-stop step needle gauge 11, and the operating cabinet 1 is also provided with an alarm electrically connected to the distance sensor 12 (not shown);

[0035] As shown above, when the second cylinder 10 is turned on to make the stop-step needle gauge 11 move downward to be inserted into the shrinkage hole of the metal product, if the stop-step needle gauge 11 cannot be inserted into the product through the hole, the stop-step needle gauge 11 will be exposed outside the product for a long time and the distance between the stop-step needle gauge 11 and the distance sensor 12 will be close. The distance sensor 12 will be induced to start the alarm to send out an alarm, so that the human will pay attention to the fact that the product is unqualified.

[0036] On the contrary, if the go-stop step needle gauge 11 is inserted into the product through the hole, the go-stop step needle gauge 11 will be exposed outside the product for a short distance, exceeding the sensing distance of the distance sensor 12. In this way, the distance sensor 12 cannot sense it and the alarm will not sound an alarm.

[0037] Further, refer to Figure 2 As shown, it is worth noting that two receiving boxes 26 are provided on one side of the manipulator 14, one receiving box 26 is used to store qualified metal products, and the other receiving box 26 is used to store unqualified metal products;

[0038] By providing two receiving boxes 26, after the metal products are tested by the testing mechanism, the robot 14 can clamp the products again to classify and store qualified and unqualified products.

[0039] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that it also includes a vibration plate 2 arranged on the other side of the top surface of the operating cabinet 1;

[0040] By setting the vibration plate 2 and developing the vibration plate 2 according to the shape of the product, the direct opening of the product can be kept vertically upward when the product is discharged from the vibration plate 2, so as to facilitate the manipulator 14 to set the product opening vertically upward directly under the punch head 7 and the through-stop step needle gauge 11, thereby reducing the adjustment of the workpiece.

[0041] Further, refer to Figure 2 As shown, it is worth noting that a processing seat 13 is provided directly below the punch head 7 and the pass-stop step needle gauge 11, one of the processing seats 13 is detachably connected to the base 3 by bolts, and the other processing seat 13 is detachably connected to the top surface of the operating cabinet 1 by bolts, and a positioning groove is provided at the top of the processing seat 13;

[0042] Through the setting of the processing seat 13, when the product is placed directly under the punch head 7 and the pass-stop step needle gauge 11, the robot 14 can put the product into the positioning groove on the processing seat 13, and use the positioning groove to position the product to ensure the stability of the product during hole expansion and hole mouth quality inspection.

[0043] Further, refer to Figure 2-5 As shown, it is worth noting that a fixed rod component is provided between the movable seat 9 and the pass-stop step needle gauge 11;

[0044] The fixed rod component includes a manipulator 14 transversely fixed on a side of the movable seat 9 facing the pass-stop step needle gauge 11, and the manipulator 14 is symmetrically slidably provided with two chucks 16 on one side of the pass-stop step needle gauge 11, and the two chucks 16 are provided with grooves adapted to the pass-stop step needle gauge 11 on the corresponding sides;

[0045] A slide groove is provided on the side of the manipulator 14 away from the movable seat 9, and a bidirectional screw 17 is vertically rotatably provided on the inner wall of one side of the slide groove. Two sliders are symmetrically threadedly connected on the rod body of the bidirectional screw 17, and the two sliders are respectively fixedly connected to the two chucks 16;

[0046] The knob bidirectional screw 17, the two sliders slide towards each other along the rod of the bidirectional screw 17 under the threaded structure, so that the two chucks 16 slide towards each other synchronously until the go-stop step needle gauge 11 is embedded in the embedding groove of the chuck 16, and the two chucks 16 cooperate with each other to achieve fixed clamping of the go-stop step needle gauge 11, ensuring the fixation of the go-stop step needle gauge 11 on the movable seat 9.

[0047] The above-mentioned method of using two sets of clamps 16 to clamp the pass-stop step needle gauge 11 in opposite directions can easily make the pass-stop step needle gauge 11 rigidly fixed. In order to facilitate the pass-stop step needle gauge 11 to detect the pass degree of the product, it is necessary to fix the movement stroke of the second cylinder 10 to a range sufficient for the pass-stop step needle gauge 11 to penetrate the inner side of the product. When the pass-stop step needle gauge 11 tests the unqualified product under the fixed stroke of the second cylinder 10, the pass-stop step needle gauge 11 will be blocked by the orifice of the unqualified product in advance, and then the pass-stop step needle gauge 11 is easy to rigidly squeeze the orifice of the unqualified product during the further penetration into the product, resulting in deformation and rupture of the product orifice, so that the product is scrapped, which is not conducive to secondary rework;

[0048] For this purpose, refer to Figure 4 and Figure 5 As shown, it is worth noting that the fixed rod component includes a positioning sleeve 18 sleeved on the rod body of the pass-stop step needle gauge 11 and a connecting block 19 fixed between the positioning sleeve 18 and the movable seat 9, and the top of the pass-stop step needle gauge 11 is tightly sleeved with a positioning piece 20 that abuts against the top surface of the positioning sleeve 18;

[0049] By setting the positioning sleeve 18 and the positioning sheet 20, when the movable seat 9 is used to move the pass-stop step needle gauge 11 downward to contact the unqualified product, the pass-stop step needle gauge 11 can be kept fixed and slide upward in the opposite direction relative to the inner side of the positioning sleeve 18 during the further downward movement of the movable seat 9 after being resisted, so as to avoid the hole of the product squeezed by the pass-stop step needle gauge 11 from being deformed and broken, thereby reducing the impact on the quality of the product;

[0050] Furthermore, the positioning piece 20 can be used to prevent the pass-stop step needle gauge 11 from falling off from the inner side of the positioning sleeve 18 under gravity, thereby affecting the use effect.

[0051] Further, refer to Figure 5 As shown, it is worth noting that an L-shaped connecting pipe 22 is provided between the positioning sleeve 18 and the movable seat 9, an annular groove is provided on the inner wall at the top of the positioning sleeve 18, an oil storage cavity 21 is provided in the inner wall of the movable seat 9, one end of the connecting pipe 22 is fixedly inserted into the annular groove, the other end of the connecting pipe 22 is fixedly inserted into the oil storage cavity 21, a sponge cover 23 is provided in the annular groove, a wire rope 24 is provided in the connecting pipe 22, one end of the wire rope 24 extends to the inner bottom of the oil storage cavity 21, and the other end of the wire rope 24 is inserted into the inner side of the sponge cover 23;

[0052] By setting the sponge sleeve 23 and the rope 24, during the long-term telescopic and sliding process of the go-stop step needle gauge 11 inside the positioning sleeve 18, one end of the rope 24 located inside the oil storage chamber 21 contacts and absorbs the lubricating oil stored in the oil storage chamber 21, so that the lubricating oil penetrates the sponge sleeve 23. In this way, when the go-stop step needle gauge 11 telescopes inside the positioning sleeve 18, the lubricating oil on the sponge sleeve 23 can coat the outer wall of the go-stop step needle gauge 11, thereby effectively reducing the friction between the go-stop step needle gauge 11 and the inner wall of the positioning sleeve 18, reducing the wear of both, and improving the service life.

[0053] Further, refer to Figure 4 As shown, it is worth noting that a liquid filling hole connected to the oil storage chamber 21 is opened on the top of the movable seat 9, and a plug 25 is inserted into the liquid filling hole;

[0054] By setting the filling hole and the plug 25, the filling hole can be used to quickly add lubricating oil to the oil storage chamber 21 when the lubricating oil in the oil storage chamber 21 is insufficient, and after the lubricating oil is added, the plug 25 is inserted into the filling hole, so that the filling hole can be effectively blocked, thereby ensuring the sealing of the oil storage chamber 21 and reducing the contamination of the lubricating oil by impurities in the external environment.
