Description

Technical Field

[0001] The utility model belongs to the field of bent pipe detection, in particular to a loading and unloading device for detecting metal bent pipes. Background Art

[0002] Metal bends, especially U-shaped ones, are common materials in the construction industry. After being purchased, metal bends can generally be sampled and tested according to demand to ensure that they meet the use standards.

[0003] Before testing a metal pipe bend, a loading and unloading device is typically used to load and unload the pipe. In existing technology, this loading and unloading device often includes a robotic arm that clamps the pipe and then transfers it to an inspection station, where a clamping fixture holds the pipe in place while it awaits inspection. Once testing is complete, the clamping fixture releases the pipe, and the robotic arm transfers it to the unloading station. While this method can still load and unload the pipe, it is a complex and inefficient process. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a loading and unloading device for detecting metal bends, aiming to solve the problem that the loading and unloading process of the existing loading and unloading device for detecting metal bends is relatively complicated and inefficient.

[0005] The utility model adopts the following technical solutions:

[0006] The loading and unloading device includes a machine platform, which has a middle opening, and a loading mechanism and a slide are respectively provided in front and behind the middle opening, and a discharge rack is provided on the right side of the slide. The slide is provided with a base, and a pair of connecting rods are passed through the bottom surface of the base facing upward, and a top seat matching the base is provided on the connecting rod, and the top seat is located on the base, and the bottom surface of the top seat and the top surface of the base are both provided with a U-shaped groove, and a spring is provided on the connecting rod below the base, and the base has a pushing opening passing through the U-shaped groove, and a pushing mechanism is provided in the middle opening facing the slide and the discharge rack, and a sliding cylinder for driving the slide to slide left and right is also provided on the machine platform.

[0007] Furthermore, the pushing mechanism includes a pushing cylinder installed in the middle opening, the driving shaft of the pushing cylinder is provided with a pushing plate, and the pushing plate is provided with a pushing block matching the pushing opening.

[0008] Furthermore, the length of the push plate is greater than the distance between the two connecting rods.

[0009] Furthermore, the feeding mechanism includes a cylindrical vibrating disk and a support platform, a discharge rack is connected between the outlet of the cylindrical vibrating disk and the support platform, a discharge trough is opened on the support platform in the discharge rack, a feeding cylinder is provided on the back of the support platform on the machine platform, and a push block is provided on the driving shaft of the feeding cylinder, and the front end of the push block is arranged toward the discharge trough.

[0010] Furthermore, a guide rod is provided in the blanking rack.

[0011] The beneficial effects of the present utility model are as follows: first, the pushing mechanism of the loading position pushes the two connecting rods to move upward for a distance at the same time, and the top seat is lifted up together with the connecting rods. The top seat is a short distance away from the base and forms a loading inlet. Then, the loading mechanism pushes the metal elbow into the lower U-shaped groove, and the pushing mechanism resets and under the action of the spring, the connecting rod drives the top seat to move downward until the top seat falls on the base again. At this time, the elbow is located in the upper and lower U-shaped grooves. Finally, the sliding cylinder drives the slide seat to move to the detection unloading position, and the relevant detection mechanism can be used to detect the pipe ends of the elbow.

[0015] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0017] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0018] Combine Figure 1-3As shown, the loading and unloading device includes a machine 1, which has a middle opening 2. A loading mechanism and a slide 3 are respectively provided in front and behind the middle opening 2. A discharge rack 4 is provided on the right side of the slide 3. A base 5 is provided on the slide 3. A pair of connecting rods 6 extend upward from the bottom surface of the base 5. A top seat 7 matching the base 5 is provided on the connecting rod 6, and the top seat 7 is located on the base 5. U-shaped grooves 8 are provided on the bottom surface of the top seat 7 and the top surface of the base 5, wherein the U-shaped groove on the bottom surface of the top seat is marked as an upper U-shaped groove, and the U-shaped groove on the top surface of the base is marked as a lower U-shaped groove. A spring 9 is provided on the connecting rod 6 below the base 5. The base 5 has a push opening 10 extending through the U-shaped groove 8. A push mechanism is provided in the middle opening 2 facing the slide 3 and the discharge rack 4. The machine 1 is also provided with a sliding cylinder 11 for driving the slide 3 to slide left and right.

[0019] Metal bends, especially U-shaped ones, are common materials in the construction industry. After being purchased, metal bends can generally be sampled and tested according to demand to ensure that they meet the use standards.

[0020] In this structure, the middle opening is provided with a pushing mechanism corresponding to the slide and the unloading rack. Before testing the metal bend, the slide is located at the loading position, the unloading rack is located at the testing unloading position, and the loading position and the testing unloading position are both provided with the pushing mechanism.

[0021] When metal bends need to be inspected one by one and in an orderly manner, the slide is previously located at the loading position. First, the pushing mechanism at the loading position pushes the two connecting rods upward for a distance at the same time. The top seat is lifted up along with the connecting rods, and the spring is gradually compressed during this process. The top seat is a short distance away from the base and forms a loading inlet. Then the loading mechanism pushes a metal bend toward the loading inlet until the metal bend is pushed into the lower U-shaped groove. After that, the pushing mechanism resets and, under the action of the spring, the connecting rod drives the top seat downward until the top seat falls back onto the base. At this time, the metal bend is located in the upper and lower U-shaped grooves. Finally, the sliding cylinder drives the slide to move to the detection unloading position, and the relevant detection mechanism can be used to detect the two ends of the pipe opening of the bend.

[0022] When the metal bend is located in the upper and lower U-shaped grooves, the U-shaped grooves are in a compressed state. In this way, when the metal bend is inspected, the U-shaped grooves will not shake, thereby improving the accuracy of the inspection results.

[0023] As a preferred structure, Figure 2 The pushing mechanism includes a pushing cylinder 12 installed in the middle port 2, the driving shaft of the pushing cylinder 12 is provided with a pushing plate 13, and the pushing plate 13 is provided with a pushing block 14 matching the pushing port 10.

[0024] Once the inspection is complete, the push cylinder drives the push plate upward, simultaneously pushing the connecting rod and push block upward. The connecting rod pushes the top seat upward and away from the base, while the push block moves upward within the push opening. After exiting the push opening, the push block continues upward a short distance, pushing the corresponding position of the metal bend outward until the metal bend slides through the lower U-shaped opening and onto the unloading rack, completing the unloading process. Finally, the push cylinder resets, and the top seat, driven by the spring, falls back onto the base. The sliding cylinder drives the slide back to the loading position.

[0025] In this embodiment, if Figure 2 A material guide 23 is also located on the push plate at the material discharge detection point. After the metal bend is inspected, a push cylinder located at the material discharge detection point drives the push plate upward, causing the material guide to move upward. Before the metal bend is pushed out of the lower U-shaped opening, the bottom of the material guide aligns with the top of the material discharge base. After the metal bend is pushed out of the lower U-shaped opening, it passes through the material guide and slides from the discharge base to the designated position.

[0026] It is worth noting that: during the loading process of the metal elbow, the pushing mechanism located at the loading position drives the top seat away from the base for a short distance and forms a loading inlet. At this time, the pushing block is still located in the pushing inlet.

[0027] Since the length of the push plate is greater than the distance between the two connecting rods, the push block can simultaneously push the two connecting rods upward.

[0028] As a preferred structure, Figure 1 The feeding mechanism includes a cylindrical vibrating disk 16 and a support platform 17. A discharge rack 18 is connected between the outlet of the cylindrical vibrating disk 16 and the support platform 17. A blanking trough (blocked in the figure) is opened on the support platform 17 and located inside the discharge rack 18. A feeding cylinder 20 is provided on the back side of the support platform 17 on the machine 1. The driving shaft of the feeding cylinder 20 is provided with a pushing block 21, and the front end of the pushing block 21 is arranged toward the blanking trough.

[0029] In the above structure, a number of bent metal pipes to be inspected are placed in the cylindrical vibrating plate. The plate delivers them one by one in an orderly fashion to a discharge rack, where several bent metal pipes are stacked. The lowest bent metal pipe is located in the discharge chute. When the bent metal pipes are to be delivered one by one in an orderly fashion to the loading inlet, the loading cylinder drives the push block, which pushes the lowest bent metal pipe toward the loading inlet until it is pushed into the loading inlet. Finally, the push block resets, and the next bent metal pipe falls into the discharge chute.

[0030] In addition, the feed rack 4 is provided with a guide rod 22. When the cylindrical vibrating plate feeds the metal bends one by one and in an orderly manner into the feed rack, the guide rod is located inside the metal bends, and the metal bends move downward along the length of the guide rod, which guides and limits the metal bends, making the metal bends more stable during the feeding process.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
