DETAILED DESCRIPTION

[0032] The utility model will be further described below in combination with the embodiments shown in the drawings.

[0033] As shown in Figure 3 , 4 , it is a structure schematic view of the perforation detection jig of the utility model, and is usually used for perforation detection of the product shown in Figure 1 , 2 (ie, perforation detection of the steam hole on the product, to avoid the steam hole being blocked by foreign matter when the product is injection molded, thereby affecting normal use). The perforation detection jig comprises a support frame, a bearing assembly, a lifting plate 8 and a perforation assembly, etc. The support frame mainly plays a supporting role, and is used for supporting and installing the bearing assembly. The support frame comprises a foot pad 1, a bottom plate 2, a support column 3, a top plate 4 and a downward pressing cylinder 5.

[0034] The foot pad 1 is fixed at the bottom of the bottom plate 2, and is used for supporting the bottom plate 2, to avoid the bottom plate 2 being in direct contact with the tabletop, and to avoid the tabletop having accumulated water to cause the bottom plate 2 to be rusted (specifically, the material of the foot pad 1 is rubber, the foot pad 1 is at least four, and is fixed at the bottom of the bottom plate 2 by means of screw fastening, and the foot pad 1 is distributed at the four corners of the bottom of the bottom plate 2, to improve the stability of the support of the bottom plate 2).

[0035] The support column 3 is fixed at the top of the bottom plate 2, and the top plate 4 is fixed at the top of the support column 3, and is used for installing the downward pressing cylinder 5 (specifically, the support column 3 is vertically fixed at the top of the bottom plate 2 by means of welding, and the top plate 4 is fixed at the top of the support column 3 by means of screw fastening or welding). The support column 3 is at least four, and is distributed at the four corners of the bottom of the top plate 4, to improve the stability of the support of the top plate 4.

[0036] The top plate 4 is supported up by the support column 3, to ensure that there is enough operating space between the top plate 4 and the bottom plate 2, to facilitate the operator to take and place the product.

[0037] The cylinder body of the downward pressing cylinder 5 is fixed on the upper surface of the top plate 4 by means of screw fastening, the piston rod of the downward pressing cylinder 5 penetrates through the top plate 4 and is connected with the lifting plate 8, the lifting plate 8 is driven to descend by the downward pressing cylinder 5, and then the perforation detection of the product is completed (specifically, a through hole is formed in the top plate 4, the piston rod of the downward pressing cylinder 5 penetrates through the through hole, and then the piston rod and the lifting plate 8 are fixed together by means of welding; when welding, the connecting position of the piston rod and the lifting plate 8 is aligned, and the piston rod is welded on the lifting plate 8 by using a welding device such as electric arc or argon arc welding).

[0038] The guide sleeve 7 is embedded in the top plate 4, and the guide column 6 is fixed at the top of the lifting plate 8 and penetrates through the guide sleeve 7 by means of welding (specifically, a guide sleeve hole is formed in the top plate 4 in the vertical direction, the guide sleeve 7 is embedded in the guide sleeve hole, and then the guide sleeve 7 is fixed on the top plate 4 by means of screw fastening).

[0039] By setting up mutually cooperating guide columns 6 and guide sleeves 7, when the pressing cylinder 5 drives the lifting plate 8 to rise and fall, the lifting plate 8 will drive the guide column 6 to rise and fall synchronously along the guide sleeve 7, thereby improving the stability of the lifting plate 8 and preventing it from deviating, thus improving the accuracy of perforation detection and preventing the insertion rod from damaging the surface of the product.

[0040] The support assembly is mounted on top of the base plate 2 to support the product to be perforated, such as... Figure 7 , 8 As shown, the supporting components include a jig plate 24, a contour groove 25, a protrusion 26, a groove 27, a stop block 28, an adjustment groove 29, and a side slot 30. The jig plate 24 is fixed to the upper surface of the base plate 2 by screws. The contour groove 25 is formed on the upper surface of the jig plate 24 and matches the shape of the product to be perforated. During actual testing, the operator places the product to be perforated into the contour groove 25 of the jig plate 24.

[0041] The protrusion 26 is integrally connected to the top of the jig plate 24, such as... Figure 2 As shown, the bottom of the product to be pierced is provided with a groove structure, and the protrusion 26 cooperates with the groove structure at the bottom of the product to be pierced. When the operator places the product on the contour groove 25 from top to bottom, the groove structure at the bottom of the product to be pierced is inserted into the protrusion 26, which plays a role in positioning the product and preventing the product from being pressed crooked during piercing.

[0042] The groove 27 is formed on the top of the jig plate 24. The cross section of the groove 27 from top to bottom is rectangular. It is used to block and limit the stop block 28, ensuring that the stop block 28 can only slide along the long side of the groove 27 to abut against the product to be perforated, and to prevent the stop block 28 from swinging and affecting the tightness of the product.

[0043] The abutment 28 is installed in the groove 27, and the length of the abutment 28 is less than the length of the groove 27, ensuring that the abutment 28 has room to move and adjust along the length direction of the groove 27. The width of the abutment 28 is equal to the width of the groove 27, so the groove 27 will limit the adjustment of the abutment 28, ensuring that the abutment 28 can only slide along the length direction of the groove 27 and prevent it from swinging.

[0044] The adjustment groove 29 is formed at the bottom of the groove 27 and extends through the fixture plate 24, such as... Figure 9 As shown, the adjusting groove 29 is an oblong groove (that is, the shape of the adjusting groove 29 when viewed from above is a rounded rectangle. The fastening bolt 19 passes through the adjusting groove 29 and is fixed to the bottom of the abutment block 28. When the abutment block 28 is moved, the fastening bolt 19 will move along the length of the adjusting groove 29, and then the abutment block 28 will press the product to be perforated against it).

[0045] like Figure 9As shown, the adjusting groove 29 is a countersunk structure, that is, the adjusting groove 29 comprises an adjusting main groove and an adjusting auxiliary groove, the adjusting main groove is opened at the bottom of the groove 27, and the adjusting auxiliary groove is opened at the bottom of the adjusting main groove (wherein the adjusting main groove and the adjusting auxiliary groove are both in the shape of a waist, but the size of the adjusting auxiliary groove is slightly larger than the size of the adjusting main groove, for accommodating the bolt head of the fastening bolt, to avoid interference between the bolt head and the bottom plate 2 during installation).

[0046] The fastening bolt comprises a bolt head and a bolt root, the outer circumferential surface of the bolt root is provided with external threads, and the bottom of the abutting block 28 is provided with a threaded hole matched with the bolt root. In actual installation, first, the abutting block 28 is inserted into the groove 27 of the jig plate 24 (specifically, the length direction of the abutting block 28 is parallel to the length direction of the groove 27, and the width direction of the abutting block 28 is parallel to the width direction of the groove 27), and then the fastening bolt is fixed at the bottom of the abutting block 28 by being passed through the adjusting groove 29 from bottom to top (specifically, the bolt root is screwed into the threaded hole at the bottom of the abutting block 28 by passing through the adjusting main groove, and the bolt head is placed in the adjusting auxiliary groove, and under the clamping action of the shoulder formed by the adjusting auxiliary groove and the adjusting main groove, the abutting block 28 can only slide along the length direction of the groove 27 for adjustment, and cannot be pulled out of the groove 27).

[0047] The fastening bolt is fixed at the bottom of the abutting block 28 by passing through the adjusting groove 29, and the fastening bolt is not completely screwed into the adjusting groove 29, otherwise the operator cannot push the abutting block 28 along the length direction of the groove 27. Therefore, during actual screwing of the fastening bolt, the fastening bolt is not completely tightened, and a gap is left between the bolt head and the upper surface of the adjusting auxiliary groove, which facilitates the operator to push the abutting block 28 forward while avoiding the abutting block 28 from being pulled out of the groove. After the abutting block 28 is installed, the jig plate 24 is fixed on the upper surface of the bottom plate 2 by screw fastening (at this time, the bolt head of the fastening bolt is placed in the adjusting auxiliary groove to avoid interference with the bottom plate 2).

[0048] As shown in Figure 7 , 8 , a rectangular groove is opened at the top of the abutting block 28, which is matched with the index finger of the operator. During actual detection, the operator first places the product in the profiling groove 25 of the jig plate 24, and then places the index finger in the rectangular groove at the top of the abutting block 28, and pushes the abutting block 28 towards the side of the product to abut against the inner side wall of the product.

[0049] The side insertion groove 30 is opened at the side of the abutting block 28 close to the product to be perforated, and is matched with the structure of the inner side of the product to be perforated. After the operator places the product in the profiling groove 25 of the jig plate 24, the abutting block 28 is pushed along the length direction of the groove 27 until the side insertion groove 30 of the abutting block 28 is inserted into the side of the product to be perforated. In this way, the product can be prevented from being pressed and distorted during perforation.

[0050] As Figure 5 , 6 shown, the perforation assembly is installed at the bottom of the lifting plate 8. Under the drive of the downward cylinder 5, the perforation detection of the finished product is completed, and the steam hole of the product is prevented from being blocked to affect the normal use. The perforation assembly includes a first pressing plate 9, a first guide hole 10, a second pressing plate 11, a second guide hole 12, a sleeve plate 13, a guide column 14, a spring 15, a threaded hole 16, a through hole 17, a containing hole 18, a bolt 19, a plug rod, a sleeve groove 22 and an avoiding groove 23. The first pressing plate 9 is fixed on the bottom of the lifting plate 8 by screwing, and the second pressing plate 11 is fixed on the bottom of the first pressing plate 9 by screwing. Therefore, when the lifting plate 8 is driven to descend by the downward cylinder 5, the first pressing plate 9 and the second pressing plate 11 will be driven to descend synchronously.

[0051] The first guide hole 10 has at least two and penetrates the first pressing plate 9 in the vertical direction. The first guide hole 10 is respectively close to the two sides of the first pressing plate 9, providing an avoiding space for the subsequent installation of the plug rod. The second guide hole 12 has at least two and penetrates the second pressing plate 11 in the vertical direction, and cooperates with the first guide hole 10 (the first guide hole 10 is respectively close to the two sides of the first pressing plate 9, and the second guide hole 12 is also respectively close to the two sides of the second pressing plate 11, so as to improve the stability of the overall structure and avoid the inclination thereof to affect the subsequent detection).

[0052] The guide column 14 is fixed on the top of the sleeve plate 13 by welding, and penetrates the first pressing plate 9, the second pressing plate 11 and the lifting plate 8 (specifically, the third guide hole is provided on the lifting plate 8 and cooperates with the first guide hole 10, and the guide column 14 penetrates the first guide hole 10 of the first pressing plate 9, the second guide hole 12 of the second pressing plate 11 and the third guide hole of the lifting plate 8).

[0053] The first guide hole 10, the second guide hole 12 and the third guide hole are provided with linear bearings, and the guide column 14 passes through the linear bearings (the linear bearings are not shown in the figure). The linear bearings guide the lifting movement of the guide column 14 and improve the accuracy of the perforation position.

[0054] The spring 15 is sleeved on the guide column 14 and located between the second pressing plate 11 and the sleeve plate 13. The spring 15 assists the first pressing plate 9 and the second pressing plate 11 to reset after the plug rod perforation detection.

[0055] The sleeve groove 22 is provided at the bottom of the sleeve plate 13. When the lifting plate 8 is driven to descend by the downward cylinder 5, the first pressing plate 9, the second pressing plate 11 and the sleeve plate 13 will be driven to descend synchronously, and the sleeve groove 22 is buckled on the top of the product to be perforated (the sleeve groove 22 cooperates with the top structure of the product to be perforated), so as to position the product to be perforated. The avoiding groove 23 is provided at the top of the sleeve groove 22 and is used to avoid the protruding structure on the top of the product.

[0056] The insertion rod comprises a rod head 20 and a rod tail 21. The top of the second pressing plate 11 is provided with a rod head slot. A rod tail slot is provided at the bottom of the rod head slot and penetrates through the second pressing plate 11 and the sleeve plate 13. The rod tail slot is connected with the avoiding slot. When the lifting plate 8 is lowered, the insertion rod can pass through the avoiding slot 23 and be inserted into the steam hole of the product. In actual installation, the rod tail 21 is inserted into the rod tail slot, and the rod head 20 is inserted into the rod head slot of the second pressing plate 11. Then, the first pressing plate 9 is fixed on the top of the second pressing plate 11 by screwing, so as to complete the pressing of the insertion rod and avoid the swinging of the insertion rod during the detection of the perforation.

[0057] The threaded hole 16 penetrates through the second pressing plate 11. The through hole 17 penetrates through the sleeve plate 13 and is coaxially arranged with the threaded hole 16. The accommodating hole 18 is provided at the bottom of the through hole 17 and has a diameter larger than that of the through hole 17 (the inner surface of the threaded hole 16 is provided with an internal thread, and the inner surface of the through hole 17 is a smooth surface and is not provided with a thread structure).

[0058] The bolt 19 is screwed into the threaded hole 16 of the second pressing plate 11 from bottom to top through the through hole 17 (the bolt 19 comprises a bolt head and a bolt tail. The outer surface of the bolt tail is provided with an external thread, and the diameter of the through hole 17 is slightly larger than the outer diameter of the bolt tail. The bolt tail is screwed into the threaded hole 16 of the second pressing plate 11 through the through hole 17, and the bolt head is abutted against the shoulder part of the through hole 17 and the accommodating hole 18. The accommodating hole 18 is used for accommodating the bolt head).

[0059] Since the bolt tail is threadedly connected with the threaded hole 16 of the second pressing plate 11, and the bolt head is clamped on the shoulder part of the through hole 17 and the accommodating hole 18, the sleeve plate 13 is indirectly mounted on the bottom of the second pressing plate 11 through the bolt 19. Under the action of the bolt 19, the sleeve plate 13 will not fall off from the bottom of the second pressing plate 11.

[0060] When the lifting plate 8 is lowered by the lower pressing cylinder 5, the first pressing plate 9, the second pressing plate 11 and the sleeve plate 13 are synchronously lowered. When the sleeve plate 13 is lowered to abut against the product (at this time, the sleeve groove 22 at the bottom of the sleeve plate 13 is buckled on the top of the product), the lower pressing cylinder 5 continues to be lowered (since the bolt tail is threadedly connected with the threaded hole 16 of the second pressing plate 11, and the diameter of the through hole 17 is slightly larger than the diameter of the bolt tail, the first pressing plate 9, the second pressing plate 11 and the bolt 19 continue to be lowered, and the sleeve plate 13 is stationary).

[0061] The second pressing plate 11 is lowered to abut against the sleeve plate 13, at this time the spring 15 is compressed, the insertion rod is lowered to penetrate into the steam hole of the product, and the perforation detection is completed; when the lifting plate 8 is lifted by the downward pressing cylinder 5, the first pressing plate 9 and the second pressing plate 11 lift the bolt 19 to reset to abut against the shaft shoulder part of the through hole 17 and the accommodating hole 18 again, and the spring 15 is reset; the lifting plate 8 is continuously lifted by the downward pressing cylinder 5, the sleeve plate 13 is lifted by the bolt 19 to separate from the product, and the operator takes down the detected product and puts a new product again.

[0062] When it is needed to confirm whether the steam small hole of the product is blocked after the product is assembled, the product is loaded into the jig and fixed by the slide block in the positioning tool (that is, the product is placed in the profiling groove 25 of the jig plate 24, the abutting block 28 is pushed inward until the abutting block 28 abuts against one side of the product); the lifting plate 8 is lowered by the downward pressing cylinder 5, the sleeve plate 13 is lowered to be buckled on the top of the product in the sleeve groove 22, and then the first pressing plate 9 and the second pressing plate 11 continue to be lowered until the second pressing plate 11 abuts against the top of the sleeve plate 13, at this time the insertion rod penetrates into the steam hole of the product, and the blockage problem is realized to be detected and conducted.

[0063] In this process, the operation efficiency is effectively improved, the advantages of replacing manual operation by equipment are achieved, the problem that the needle rod accidentally touches and scratches the product is avoided, and the problem of hole blockage by foreign matters is controlled, and the above process is repeatedly cycled to improve the efficiency, stabilize the quality and achieve the goal of lean management.

[0064] The above embodiments are only for describing the technical concept and characteristics of the utility model, the purpose is to enable people skilled in the art to understand the content of the utility model and implement it, and it cannot limit the protection scope of the utility model. Any equivalent change or modification according to the spirit and essence of the utility model should be covered in the protection scope of the utility model.
