Description

Technical Field

[0001] This utility model relates to the field of magnetic particle inspection, specifically to an automatic feeding device for a flaw detector. Background Technology

[0002] This solution involves a wide variety of product models and sizes. Since production is done on an assembly line, flaw detection is integrated with the line to ensure product quality. The existing flaw detection structure involves conveying products to the flaw detector via a conveyor chain. However, this presents several problems. First, the bottom of the product contacts the conveyor chain, creating blind spots during magnetic powder spraying, preventing even spraying and resulting in inaccurate detection. Second, the chain drive has significant errors, often leading to loose clamping during flaw detection, causing sparking, smoke, and material misalignment. Furthermore, to ensure conveyor stability, product positioning fixtures are typically installed on each conveyor chain. Due to the large number of product models and sizes, these fixtures must be replaced every time a new product is produced, resulting in cumbersome disassembly and wasted time.

[0003] To address the aforementioned problems, this utility model designs and manufactures an automatic feeding device for a flaw detector to overcome the above-mentioned defects. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides an automatic feeding device for a flaw detector, which can ensure the stability of forging positioning and the accuracy of flaw detection.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic feeding device for a flaw detector, including a support, a conveyor chain plate on the support, the conveyor chain plate being able to convey forgings, a transfer robot being provided above the conveyor chain plate, and the transfer robot being mounted on the support;

[0006] A forging support frame is also provided above the conveyor chain plate. The forging support frame is installed on the bracket. A forging positioning seat is installed on the forging support frame. The transfer robot can transfer the forgings on the conveyor chain plate to the forging positioning seat.

[0007] It also includes a flaw detector clamping device, which is mounted on a support and along the conveyor chain conveyor direction. The flaw detector clamping device is located behind the forging positioning seat, and the transfer robot can transfer the forging on the forging positioning seat to the flaw detector clamping device.

[0008] Preferably, it also includes a magnetic powder spraying device, which is mounted on the bracket;

[0009] The magnetic powder spraying device includes an upper nozzle and a lower nozzle. The upper nozzle faces the top of the forging held by the flaw detector clamping device, and the lower nozzle faces the bottom of the forging held by the flaw detector clamping device.

[0010] Preferably, the flaw detector clamping device includes a movable arm and a stationary arm, wherein the movable arm is capable of moving relative to the stationary arm above the conveyor chain plate.

[0011] Preferably, the forging positioning seat is detachably mounted on the forging support frame.

[0012] Preferably, the top of the forging positioning seat is provided with a first sensor, which can detect whether the forging is accurately placed on the forging positioning seat.

[0013] Preferably, when the flaw detector clamping device clamps the forging, there is a gap between the forging and the conveyor chain plate.

[0014] Preferably, a liquid storage tank is provided on the support around the conveyor chain plate, and the flaw detection fluorescent magnetic powder liquid sprayed by the magnetic powder spraying device falls into the liquid storage tank after being sprayed onto the forging.

[0015] Preferably, the bracket is further provided with a second sensor, which is located in front of the forging positioning seat along the conveying direction of the conveyor chain plate;

[0016] After the second sensor detects the forging, the transfer robot moves the forging detected by the second sensor on the conveyor chain to the forging positioning seat.

[0017] Preferably, it also includes a controller, and the drive device that drives the conveyor chain plate to move, the first sensor, the second sensor, the transfer robot, and the flaw detector clamping device are all connected to the controller.

[0018] The advantages of this utility model are:

[0019] 1. In this invention, the forging is held at both ends by a flaw detector clamping device, which puts the forging in a suspended state. The magnetic powder spraying device can spray the entire surface of the forging to be inspected, ensuring the accuracy of the flaw detection.

[0020] 2. The conveyor chain plate of this utility model only has the function of conveying. There is no need to install a positioning forging structure on the conveyor chain plate. The positioning requirements of the forging can be met by using a single forging positioning seat. When facing forgings of different specifications and sizes, only one forging positioning seat needs to be replaced, which greatly reduces the problem of replacing the positioning forging structure on the production line after the forging specifications and sizes are changed.

[0021] 3. This utility model uses a forging positioning seat to position the forging, and then uses a transfer robot to accurately clamp the forging to the designated position, ensuring the accuracy of the forging's position in the flaw detector clamping device and avoiding problems such as sparking, smoke, and material slippage.

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0028] like Figures 1 to 4 As shown, an automatic feeding device for a flaw detector includes a support 1, a conveyor chain plate 2 on the support 1, the conveyor chain plate 2 is capable of conveying forgings, and a transfer robot 5 is provided above the conveyor chain plate 2, the transfer robot 5 is mounted on the support 1.

[0029] Above the conveyor chain plate 2, there is also a forging support frame 3, which is installed on the bracket 1. The forging support frame 3 is equipped with a forging positioning seat 4. The transfer robot 5 can transfer the forgings on the conveyor chain plate 2 to the forging positioning seat 4. The forging positioning seat 4 can correct and position the forgings that deviate during the conveying process. Of course, the correction and positioning here only refers to the correction when there is a small deviation. If there is a large deviation, the forging will not be able to be transferred to the forging positioning seat 4. In this case, a first sensor is provided on the top of the forging positioning seat 4. The first sensor can detect whether the forging has accurately fallen onto the forging positioning seat 4, so that the forging with too large deviation will be alarmed and then manually adjusted.

[0030] It also includes a flaw detector clamping device 6, which is mounted on the support 1 and along the conveying direction of the conveyor chain 2. The flaw detector clamping device 6 is positioned behind the forging positioning seat 4. The transfer robot 5 can transfer the forging from the forging positioning seat 4 to the flaw detector clamping device 6. When the flaw detector clamping device 6 clamps the forging, there is a gap between the forging and the conveyor chain 2. Specifically, the flaw detector clamping device 6 includes a movable arm 61 and a stationary arm 62. The movable arm 61 can move relative to the stationary arm 62 above the conveyor chain 2.

[0031] It also includes a magnetic powder spraying device 7, which is mounted on the bracket 1. The magnetic powder spraying device 7 includes an upper nozzle 71 and a lower nozzle 72. The upper nozzle 71 faces the top of the forging held by the flaw detector clamping device 6, and the lower nozzle 72 faces the bottom of the forging held by the flaw detector clamping device 6.

[0032] The forging is held at both ends by the flaw detector clamping device 6, which makes the forging essentially suspended. The magnetic powder spraying device 7 can spray the entire surface of the forging to be inspected, ensuring the accuracy of the flaw detection.

[0033] The forging positioning seat 4 can be detachably installed on the forging support frame 3. When faced with forgings of different specifications and sizes, only one forging positioning seat 4 needs to be replaced, which greatly reduces the problem of replacing the positioning forging structure on the production line that matches the forging specifications and sizes after the forging is changed.

[0034] The conveyor chain plate 2 of this utility model is provided with a liquid storage tank on the support 1 around it. The flaw detection fluorescent magnetic powder liquid sprayed by the magnetic powder spraying device 7 is sprayed onto the forging and then falls into the liquid storage tank.

[0035] A second sensor is also provided on the bracket 1. Along the conveying direction of the conveyor chain plate 2, the second sensor is located in front of the forging positioning seat 4.

[0036] After the second sensor detects the forging, the transfer robot 5 transfers the forging detected by the second sensor on the conveyor chain plate 2 to the forging positioning seat 4.

[0037] It also includes a controller, a drive device that moves the conveyor chain plate 2, a first sensor, a second sensor, a transfer robot 5, and a flaw detector clamping device 6, all of which are connected to the controller.

[0038] The specific working process of this utility model is as follows:

[0039] The forging is conveyed on the conveyor chain plate 2. After the second sensor detects the forging, the transfer robot 5 transfers the forging detected by the second sensor on the conveyor chain plate 2 to the forging positioning seat 4. After adjusting and positioning the forging, the transfer robot 5 transfers the forging on the forging positioning seat 4 to the flaw detector clamping device 6. Then the transfer robot 5 returns to the initial position and waits for the second sensor signal.

[0040] The forgings in the flaw detector clamping device 6 are first sprayed by the magnetic powder spraying device 7, and then the flaw detector clamping device 6 performs flaw detection. For qualified products, the flaw detector clamping device 6 is released directly, and the forgings continue to be input to the next process through the conveyor chain plate 2. For unqualified products, an alarm is triggered to prompt the operator to remove them.

[0041] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
