Abstract
Description
Technical Field
[0001] This utility model relates to the field of hook assembly testing technology, specifically an inspection device for hook assemblies. Background Technology
[0002] Hook assemblies are crucial components in lifting machinery used for grabbing and lifting loads. The hook directly bears the weight of the goods and consists of the hook body, hook tip, bend, joint, and locking device. After production, hook fittings require quality inspection. Traditional inspection methods often involve robotic arms loading the product onto the conforming mold groove of the inspection machine. A cylinder automatically clamps the product, and sensors mounted on the fixture automatically detect the gap between the product and the fixture to determine the product's quality. After inspection, the product falls into a collection box inside the inspection machine. During the fall, a cylinder controls the direction of the baffle plate, allowing qualified products to enter the qualified parts box and unqualified products to enter the unqualified parts box.
[0003] However, in practical applications, there is a certain height between the discharge port and the collection box. Directly dropping pipes can easily damage the collected pipes in the collection box, leading to pipe damage. To solve the above problem, we propose an inspection device for hook assembly. Utility Model Content
[0004] To address the problems in the background art, this utility model provides an inspection device for hook assemblies.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An inspection device for hook assemblies includes an inspection cabinet and an inspection module installed on the upper right side of the inspection cabinet. The inspection cabinet has a discharge port at its upper center and two collection boxes (one for qualified parts and one for unqualified parts) at its inner bottom. An adjustment assembly includes a support base fixedly installed on the upper right side of the inspection cabinet. An inspection platform is movably connected to the upper right side of the support base. The inspection module is fixedly installed on the upper center of the inspection platform. A lifting cylinder is located at the bottom right end of the inspection platform. A guide plate is located at the bottom center of the discharge port, driven by a push-pull cylinder. Buffer assemblies are located on the lower sides of both ends of the guide plate. Each buffer assembly includes a roller, and four sets of baffles are installed on the outer surface of the roller in a cross shape.
[0007] Preferably, the lifting cylinder is movably installed on the inner right side of the testing cabinet, and the output end of the lifting cylinder is movably connected to the bottom right side of the testing platform.
[0008] Preferably, the guide plate is movably installed in the middle of the inner side of the inspection cabinet, and the guide plate is located at the top middle of the qualified parts collection box and the unqualified parts collection box.
[0009] Preferably, the rollers are located on the lower sides of both ends of the guide plate, and support frames are movably installed at both ends of the rollers. The support frames are fixedly connected to the guide plate in a vertical direction.
[0010] Preferably, the outer surface of the baffle is covered with a rubber anti-slip pad.
[0011] Preferably, the push-pull cylinder is movably installed at the right end of the inner cavity of the testing cabinet and close to the inner wall of the testing cabinet.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this design, buffer components are installed at the bottom of both ends of the guide plate. When the pipe falls from the outlet, it will first fall onto the baffle of the buffer component. The baffle can effectively block the pipe falling from above. Then, the force on the baffle will drive the roller to rotate, which will further relieve the force. This invention can alleviate the impact force generated when the pipe falls and play a buffering and protective role, thereby effectively avoiding strong collisions between pipes and preventing damage.

[0019] The technical solution in this application embodiment is to solve the problems of the background technology mentioned above. The general idea is as follows: The main technical solution is that buffer components are provided at the bottom of both ends of the guide plate 7. When the pipe falls from the outlet 5, it will first fall onto the baffle 12 of the buffer component. The baffle 12 can effectively block the pipe falling from above. Then, the baffle 12 will drive the roller 11 to rotate under the force, which will further relieve the force. The above structure can alleviate the impact force generated when the pipe falls and play a buffer protection role, thereby effectively avoiding strong collisions between pipes and causing damage.
[0020] Example: Refer to Figures 1-4 As shown, an inspection device for hook assembly in this embodiment includes an inspection cabinet 1 and an inspection module 2 installed on the upper right side of the inspection cabinet 1. The inspection module 2 is a mature existing technology and will not be described in detail. A discharge port 5 is provided in the middle of the upper end of the inspection cabinet 1, and a qualified part collection box 9 and a non-qualified part collection box 10 are respectively provided in the bottom of the inner side of the inspection cabinet 1.
[0021] The adjustment assembly includes a support base 4, which is fixedly installed on the upper right side of the testing cabinet 1. A testing platform 3 is movably connected to the upper right side of the support base 4. A testing module 2 is fixedly installed in the upper middle part of the testing platform 3. A lifting cylinder 6 is provided at the bottom right side of the testing platform 3. The lifting cylinder 6 is movably installed on the inner right side of the testing cabinet 1. The output end of the lifting cylinder 6 is movably connected to the bottom right side of the testing platform 3.
[0022] A guide plate 7 is provided at the bottom center of the discharge port 5. The guide plate 7 is driven by a push-pull cylinder 8. Buffer components are provided on the lower sides of both ends of the guide plate 7. The buffer components include rollers 11. The sensitivity of the rollers 11 can be adjusted to provide maximum buffer protection for the falling pipe. Four sets of baffles 12 are installed on the outer surface of the rollers 11. The four sets of baffles 12 are installed in a cross shape on the outer surface of the rollers 11.
[0023] During use, activating the lifting cylinder 6 pushes the upper detection platform 3, causing it to rotate and tilt. At this time, the pipe being detected in the detection module 2 falls downwards into the discharge port 5. As the pipe falls downwards through the discharge port 5, it first contacts the guide plate 7 and then continues to fall. The pipe then lands on the baffle 12 of the buffer assembly, which rotates under force, thus guiding the pipe again. The baffle 12 effectively buffers the impact force generated when the pipe falls, preventing damage caused by excessive impact.
[0024] In some examples, the guide plate 7 is movably installed in the middle of the inner side of the inspection cabinet 1, and the guide plate 7 is located at the top middle of the qualified parts collection box 9 and the unqualified parts collection box 10.
[0025] In some examples, the roller 11 is located on the lower side of both ends of the guide plate 7. Both ends of the roller 11 are movably mounted with support frames 13. The support frames 13 are fixedly connected to the guide plate 7 in a vertical direction. The support frames 13 mainly play a role in stabilizing the rotational movement of the roller 11.
[0026] In some examples, the outer surface of the baffle 12 is covered with a rubber anti-slip pad. The anti-slip properties can increase the friction of the pipe and slow down the speed at which the pipe slides down, thereby effectively mitigating the impact force generated when the pipe falls and preventing it from directly hitting the collected pipe below, which could cause damage.
[0027] In some examples, the push-pull cylinder 8 is movably installed at the right end of the inner cavity of the inspection cabinet 1 and close to the inner wall of the inspection cabinet 1 to avoid obstructing pipes falling from above.
[0028] The working principle of this utility model is as follows:
[0029] When pipe fittings need to be inspected, the pipe fittings are first placed into the inspection mold slot in the inspection module 2 by the machine claw, and then the inspection module 2 inspects whether the pipe fittings are qualified.
[0030] When the pipe fitting is detected to be in a qualified state, the push-pull cylinder 8 located below will pull the guide plate 7, causing the guide plate 7 to tilt to the right. Then, the lifting cylinder 6 will be activated, pushing the right end of the inspection table 3, causing the inspection table 3 to rotate and tilt. At this time, the ejector cylinder inside the inspection mold groove will be activated, causing the pipe fitting to be ejected from the inspection mold groove. The pipe fitting will fall downwards and be cushioned by the buffer assembly. Then, the rotation of the baffle 12 will further unload the force and enhance the buffering effect. Furthermore, the rotation of the baffle 12 can guide the pipe fitting to the qualified part collection box 9 below, waiting for the staff to process it.
[0031] Conversely, when a defective pipe is detected, the push-pull cylinder 8 will push the guide plate 7. At this time, the pipe passes through the guide plate 7 and the buffer assembly, and then falls into the defective collection box 10 below for collection, waiting for the staff to process it.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
