Description

Technical Field

[0001] The utility model belongs to the technical field of detection devices, and in particular relates to a detection device for retained objects in nut embedding holes used for injection molding processing. Background Art

[0002] Embedded parts for injection molding refers to a processing method in which metal parts or other accessories are embedded in plastic during the injection molding process. Embedded parts for injection molding have the advantages of integrated molding, beautiful appearance, and low cost, so they are widely used in modern industrial manufacturing. Embedded nuts are a commonly used accessory in embedded parts for injection molding. Their function is to fix or connect other metal accessories. They are usually used in some injection molding structures that need to be reinforced.

[0003] Before embedding nuts in injection molded parts, the inside of the holes needs to be inspected and cleaned. When there are retained objects inside the holes, contact with the embedded nuts may cause deformation or damage during embedding or cause the nuts to loosen after embedding, affecting the embedding effect of the nuts and further affecting the structural strength and stability of the injection molded parts. In addition, there is usually more than one embedded hole in the injection molded parts, and manual inspection of the holes requires constant identification of the hole positions, which is inefficient.

[0028] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 2 , Figure 4 As shown, the utility model is a device for detecting retained objects in nut embedded holes for injection molding, comprising a support table 1, a driving mechanism 2 is arranged on the top of the support table 1, an inner through groove 3 is opened inside the support table 1, an output end of the driving mechanism 2 passes through the inner through groove 3 and is threadedly connected with a lifting frame 4, an outer surface of the lifting frame 4 is slidably connected with a detection component 5, an outer surface of the support table 1 is fixedly connected with a support block 6, an inner part of the support block 6 is slidably connected with a transverse tooth plate 7, a side surface of the transverse tooth plate 7 is meshed with a second driving mechanism 8, a positioning hole 9 is opened on the top of the transverse tooth plate 7, a positioning component 17 is arranged on the bottom of the transverse tooth plate 7, a guide clamping plate 10 is arranged on the top of the transverse tooth plate 7, and a side plate 11 is arranged on one side of the detection component 5.

[0031] When in use, the support platform 1 is placed near the injection molded part. When it is necessary to inspect the inside of the embedded hole of the nut in the injection molded part, the driving mechanism 2 is started to drive the lifting frame 4 to move downward along one side of the support platform 1 and drive the detection component 5 thereon to move downward until the lifting frame 4 gradually moves to the top close to the cross tooth plate 7 so that the side plate 11 on one side extends to the inner side of the guide clamping plate 10, and then the second driving mechanism 8 is started to drive the cross tooth plate 7 to move horizontally. At the same time, the guide clamping plate 10 on its top pushes the side plate 11 and drives the detection component 5 to move horizontally on the lifting frame 4 until the positioning component 17 at the bottom of the cross tooth plate 7 is located directly above the embedded hole and then stops moving. After the position of the bottom of the detection component 5 is consistent with the positioning hole 9 above the positioning component 17, the driving mechanism 2 drives the lifting frame 4 to continue to move downward again, driving the detection component 5 to descend so that its bottom passes through the positioning hole 9 and extends to the inside of the positioning component 17, and then gradually moves to the embedded hole below it for inspection.

[0032] The utility model sets the cross-tooth plate 7 at a position close to the bottom of the support platform 1. When it is necessary to inspect the inside of the embedded hole of the injection molded part, the detection component 5 can be lowered to the top close to the embedded hole through the driving mechanism 2 in cooperation with the lifting frame 4, and through the cooperation of the guide clamping plate 10 and the side plate 11 on the top of the cross-tooth plate 7, when the second driving mechanism 8 drives it to move laterally, it can also drive the detection component 5 to move laterally, and the aperture of the positioning hole 9 is slightly larger than the aperture of the embedded hole to be inspected, so that the cross-tooth plate 7 can drive the detection component 5 to synchronously move to the position where the embedded hole is required to be inspected, and the embedded hole can be accurately positioned and inspected, thereby improving the accuracy and efficiency of detecting the retained objects inside the embedded hole of the injection molded part, so as to facilitate the subsequent cleaning of the embedded hole with retained objects remaining inside.

[0033] In one embodiment, for the above-mentioned driving mechanism 2 , the driving mechanism 2 includes a driving motor 201 , a driving screw 202 is fixedly mounted on the output end of the driving motor 201 , and the lifting frame 4 is threadedly connected to the outer surface of the driving screw 202 .

[0034] The driving motor 201 is fixed on the top of the support platform 1. By starting the driving motor 201, the driving screw 202 can be rotated to drive the lifting frame 4 connected with the external thread to move up and down along the outside of the support platform 1, further providing a lifting driving force for the detection component 5, so that the height of the detection component 5 can be flexibly adjusted during detection.

[0035] In one embodiment, for the above-mentioned support platform 1, guide grooves 12 are opened on both sides of the inner wall of the support platform 1, and guide sliding blocks 13 are fixedly connected to the two side surfaces of the lifting frame 4. The guide sliding blocks 13 are slidably connected to the inner wall of the guide groove 12, and a limiting block 14 is set at one end of the lifting frame 4.

[0036] Since the lifting frame 4 is threadedly connected to the driving screw 202 , when the driving screw 202 rotates to drive the lifting frame 4 to move, the guide sliding blocks 13 on both sides thereof are driven to slide on the inner wall of the guide sliding groove 12 .

[0037] Through the cooperation of the guide slide blocks 13 and the guide slide grooves 12 on both sides of the lifting frame 4, the guide slide blocks 13 on both sides of the lifting frame 4 slide synchronously on the inner walls of the guide slide grooves 12 when the lifting frame 4 is displaced, so as to limit the lifting frame 4 and limit its longitudinal displacement path.

[0038] In one embodiment, for the lifting frame 4 , a connecting sleeve 15 is fixedly installed on the outer surface of the lifting frame 4 , a guide slide rod 16 is fixedly installed on the outer surface of the support platform 1 , and the connecting sleeve 15 is slidably connected to the outer surface of the guide slide rod 16 .

[0039] The guide slide rod 16 is located at the rear side of the support platform 1. When the lifting frame 4 moves, the connecting sleeve 15 at the rear side is driven to slide synchronously on the outer surface of the guide slide rod 16. This can increase the synchronous limiting effect on the rear side of the lifting frame 4 and increase the connection support strength of the lifting frame 4, so that it can drive the detection component 5 to move up and down more smoothly and stably.

[0040] In one embodiment, for the second driving mechanism 8 , the second driving mechanism 8 includes a rotating rod 801 , one end of which is fixedly mounted with a driving gear 802 , and the driving gear 802 is meshed with the cross-tooth plate 7 .

[0041] The driving gear 802 is located inside the support block 6. The driving gear 802 is driven to rotate by rotating the rotating rod 801 extending from the bottom of the support block 6 to drive the cross-tooth plate 7 to move laterally. The cross-tooth plate 7 moves to drive the guide plate 10 to push the side plate 11 to move synchronously, thereby indirectly driving the detection component 5 to move laterally outside the lifting frame 4.

[0042] By passing the cross-tooth plate 7 through the bottom of the support platform 1, and in cooperation with the rotating rod 801 and the driving gear 802, the cross-tooth plate 7 and the positioning assembly 17 can be driven to move quickly toward the embedded hole position, and then the detection assembly 5 is driven to approach the embedded hole position synchronously through the cooperation of the guide clamp plate 10 and the side plate 11, so as to achieve the effect of rapid positioning and improve the accuracy of positioning before the embedded hole detection.

[0043] In one embodiment, for the above-mentioned positioning assembly 17 , the positioning assembly 17 includes a connecting spring 1701 , a positioning sleeve 1702 is fixedly installed at the bottom of the connecting spring 1701 , and the connecting spring 1701 is located directly below the positioning hole 9 .

[0044] When the support platform 1 is placed near the belly of the injection molded part, the transverse tooth plate on one side thereof is located above the injection molded part, and the positioning sleeve 1702 is connected to the bottom of the transverse tooth plate 7 by the connecting spring 1701. Therefore, when the injection molded part has a certain height, the positioning sleeve 1702 can be elastically supported on the upper surface of the injection molded part by the connecting spring 1701 to prevent the transverse tooth plate 7 from being too low and causing friction with the surface of the injection molded part. The connecting spring 1701 and the through-type positioning sleeve 1702 facilitate providing flow space for the detection component 5 above the embedded hole, so that it can accurately enter the embedded hole for detection.

[0045] In one embodiment, for the above-mentioned detection component 5, the detection component 5 includes a sliding block 501, a threaded sleeve 502 is provided at the bottom of the sliding block 501, and a detection head 503 is threadedly connected to the bottom of the threaded sleeve 502.

[0046] The detection head 503 is connected to the bottom of the sliding block 501 through the threaded sleeve 502. When the detection head 503 is moved by the side plate 11 to the top of the embedded hole, the driving screw 202 drives the lifting frame 4 to continue to descend and drives the sliding block 501 and the detection head 503 to descend, so that the detection head 503 passes through the positioning hole 9 and extends to the inside of the connecting spring 1701. After the detection head 503 continues to descend to the inside of the embedded hole, the inside of the embedded hole can be inspected. The length of the detection head 503 is set to be the same as the inside length of the embedded hole. Then, the extension length of the detection head 503 located at the top of the embedded hole can be used to preliminarily observe whether there is any retained object.

[0047] In one embodiment, for the above-mentioned support platform 1 , a guide rail 18 is disposed at the bottom of the support platform 1 , and a bottom slide 19 is fixedly installed on the support platform 1 , and the bottom slide 19 is slidably connected to the outer surface of the guide rail 18 .

[0048] By fixing the bottom slide 19 to the bottom of the support platform 1 and slidably connected to the outside of the guide rail 18, when it is necessary to inspect the embedded holes in other positions of the injection molded part, the bottom slide 19 at the bottom of the support platform 1 can be pushed to slide on the outside of the guide rail 18, thereby driving the support platform 1 and the lifting frame 4 to move as a whole, thereby facilitating the inspection of multiple embedded holes in the injection molded part, thereby improving the flexibility and efficiency of the inspection operation.

[0049] Through the above technical scheme, 1. By setting the cross-tooth plate 7 at a position close to the bottom of the support platform 1, when it is necessary to inspect the inside of the embedded hole of the injection molded part, the detection component 5 can be lowered to the top close to the embedded hole through the driving mechanism 2 in cooperation with the lifting frame 4, and through the cooperation of the guide clamping plate 10 and the side plate 11 on the top of the cross-tooth plate 7, when the second driving mechanism 8 drives it to move horizontally, it can also drive the detection component 5 to move horizontally, and the aperture of the positioning hole 9 is slightly larger than the aperture of the embedded hole to be detected, so that the cross-tooth plate 7 can drive the detection component 5 to synchronously move to the position of the embedded hole to be detected, and accurately locate and detect the embedded hole, thereby improving the accuracy and efficiency of detecting the retained objects inside the embedded hole of the injection molded part, so as to facilitate the subsequent cleaning of the embedded hole with retained objects remaining inside; 2. By setting the cross-tooth plate 7 at a position close to the bottom of the support platform 1, when the cross-tooth plate 7 is moved horizontally, the detection component 5 can be driven to move horizontally at the same time, and the aperture of the positioning hole 9 is slightly larger than the aperture of the embedded hole to be detected, so as to improve the accuracy and efficiency of detecting the retained objects inside the embedded hole of the injection molded part, and to facilitate the subsequent cleaning of the embedded hole with retained objects remaining inside; The plate 7 passes through the bottom of the support platform 1, and with the cooperation of the rotating rod 801 and the driving gear 802, it can drive the cross-tooth plate 7 and the positioning component 17 to move quickly to the embedded hole position, and then drive the detection component 5 to approach the embedded hole position synchronously through the cooperation of the guide clamping plate 10 and the side plate 11, so as to achieve the effect of rapid positioning and improve the accuracy of positioning before the embedded hole detection; by fixing the bottom slide 19 to the bottom of the support platform 1 and slidingly connecting it to the outside of the guide rail 18, when it is necessary to detect the embedded holes in other positions of the injection molded part, the bottom slide 19 at the bottom of the support platform 1 can be pushed to slide on the outside of the guide rail 18, so as to drive the support platform 1 and the lifting frame 4 to move as a whole, so as to facilitate the detection of multiple embedded holes in the injection molded part, and improve the flexibility and efficiency of the detection operation.
