Abstract
Description
Technical Field
[0001] This utility model relates to the field of flaw detection device technology, and more specifically, to a flaw detection device for the production of automobile steering knuckles. Background Technology
[0002] A machining flaw detection device for automotive steering knuckle production refers to a general term for specialized non-destructive testing equipment used during or after the machining process of automotive steering knuckles to detect whether there are defects (such as cracks, porosity, inclusions, shrinkage cavities, etc.) on their internal or surface. For example, the machining flaw detection device for automotive steering knuckle production proposed in publication number "CN222866584U" includes a housing and a slide rail. A vertical plate is provided on the front right side of the inner side of the housing, and a short rod is movably connected to the left side of the vertical plate. The front and rear surfaces of the short rod are both provided with transverse movable grooves. A fixing block is sleeved on the outside of the short rod, and cylinders are fixed at both the upper and lower positions inside the fixing block. However, in the above technical solution, because the machining flaw detection device for automobile steering knuckle production lacks a shielding structure between its housing and the pull-out extension box, the assembly gap between the two components becomes a weak point for radiation leakage during flaw detection operations. This makes it easy for the radiation generated inside the device to leak out through this gap, posing a significant safety hazard of radiation damage to operators. Utility Model Content
[0003] The main objective of this invention is to provide a flaw detection device for the production of automotive steering knuckles. This device effectively solves the problem in the prior art where the lack of a shielding structure between the main body and the pull-out extension box of the aforementioned flaw detection device for automotive steering knuckle production results in a weak point for radiation leakage during flaw detection operations. This allows the radiation generated inside the device to easily leak out through this gap, posing a significant safety hazard of radiation damage to operators.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A flaw detection device for manufacturing automotive steering knuckles includes a housing, a linear motor is installed at the bottom of the housing, a robotic arm is installed on the upper surface of the linear motor's slide, a clamping fixture is fixedly installed at the end of the robotic arm, and a flaw detection rod is installed at the top of the housing. A movable frame is movably installed at one end of the inner wall of the box, and a sealing component is provided between the outer wall of the movable frame and the inner wall of the box.
[0005] Preferably, the sealing assembly includes a first support frame and a second support frame. The first support frame is fixedly installed on the outer wall of the movable frame, and the second support frame is fixedly installed on the outer wall of the box. A lead rubber curtain is fixedly installed between the first support frame and the second support frame.
[0006] Preferably, a number of right-angle frames are fixedly installed on the outer wall of the movable frame, and a positioning frame is fixedly installed on one end of each right-angle frame. A pushing structure for pushing is provided on one side of the upper surface of the box.
[0007] Preferably, the pushing structure includes a support base, which is fixedly installed on one side of the upper surface of the housing. A hydraulic cylinder is fixedly installed at the bottom of the support base, and the output end of the hydraulic cylinder passes through the support base and is fixedly connected to the corresponding right-angle bracket.
[0008] Preferably, each of the right-angle frames has a rotating groove on the side near the box body, and a rotating column is rotatably installed between the two sides of the inner wall of each rotating groove.
[0009] Preferably, one end of the movable frame is hinged to a sealed door.
[0010] Compared with the prior art, the present invention has the following beneficial effects: (1) When the staff controls the movement of the mobile frame, causing the first support frame on the mobile frame and the second support frame fixed on the box to move relative to each other, the lead rubber curtain connected between the two is stretched or compressed. This design ensures that the lead rubber curtain can always fill the gap between the mobile frame and the box, regardless of the position of the mobile frame, thereby preventing radiation from leaking out of the gap.

[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0014] like Figures 1-4 As shown, a machining flaw detection device for automobile steering knuckle production includes a housing 1, a linear motor 2 is installed at the bottom of the housing 1, a robotic arm 3 is installed on the upper surface of the slide of the linear motor 2, a clamping fixture 4 is fixedly installed at the end of the robotic arm 3, and a flaw detection rod 5 is installed at the top of the housing 1. A movable frame 6 is movably installed at one end of the inner wall of the box 1, and a sealing component 7 is installed between the outer wall of the movable frame 6 and the inner wall of the box 1.
[0015] The sealing assembly 7 includes a first support frame 701 and a second support frame 702. The first support frame 701 is fixedly installed on the outer wall of the movable frame 6, and the second support frame 702 is fixedly installed on the outer wall of the housing 1. A lead rubber curtain 703 is fixedly installed between the first support frame 701 and the second support frame 702.
[0016] One end of the movable frame 6 is hinged to a sealed door 9 via a hinge 8.
[0017] The operator or external automated equipment places the automotive steering knuckle to be inspected onto the clamping fixture 4 and secures it. Then, the sealing door 9 is closed, and the linear motor 2 is started, driving its slide and the robotic arm 3 mounted on it to move longitudinally along the bottom of the housing 1, initially delivering the steering knuckle to the inspection area below the flaw detector 5. The flaw detector 5 is activated, emitting inspection rays such as X-rays. At the same time, the robotic arm 3 can drive the clamping fixture 4 and the steering knuckle to perform multi-degree-of-freedom fine adjustments, such as rotation and fine-tuning positioning, to ensure that all parts of the steering knuckle to be inspected can be completely scanned, achieving all-round non-destructive testing. After the inspection is completed, the linear motor 2 drives the robotic arm 3 to return the steering knuckle to the initial position, and then the sealing door 9 is opened, allowing the operator or equipment to remove it, completing one work cycle.
[0018] When the staff controls the movement of the movable frame 6, causing the first support frame 701 on the movable frame 6 and the second support frame 702 fixedly installed on the box 1 to undergo relative displacement, the lead rubber curtain 703 connected between the two is stretched or compressed accordingly. This design ensures that no matter what position the movable frame 6 is in, the lead rubber curtain 703 can always fill the gap between the movable frame 6 and the box 1, preventing radiation from leaking out of the gap.
[0019] In another embodiment of this utility model, a plurality of right-angle frames 10 are fixedly installed on the outer wall of the movable frame 6, and a positioning frame 1001 is fixedly installed on one end of the right-angle frames 10. A pushing structure 11 for pushing is provided on one side of the upper surface of the box body 1.
[0020] The pushing structure 11 includes a support base 1101, which is fixedly installed on one side of the upper surface of the housing 1. A hydraulic cylinder 1102 is fixedly installed at the bottom of the support base 1101. The output end of the hydraulic cylinder 1102 passes through the support base 1101 and is fixedly connected to the corresponding right angle bracket 10.
[0021] When a long steering knuckle needs to be inspected, the push structure 11 is activated, the hydraulic cylinder 1102 extends, and its output end pushes the right-angle frame 10 and the entire movable frame 6 fixedly connected to it, causing it to slide outward along the inner wall of the housing 1, thereby expanding the effective inspection space inside the housing 1. During the process of the entire movable frame 6 extending or retracting, the first support frame 701 fixedly installed on the movable frame 6 and the second support frame 702 fixedly installed on the housing 1 also undergo relative displacement.
[0022] In another embodiment of this utility model, each right-angle frame 10 is provided with a rotating groove on the side near the box 1, and a rotating column 12 is rotatably installed between the two sides of the inner wall of each rotating groove.
[0023] When the hydraulic cylinder 1102 pushes or pulls the right-angle frame 10, thereby causing the entire moving frame 6 to extend or retract, the right-angle frame 10 and the inner wall surface of the housing 1 will move relative to each other. During this process, the rotating column 12 replaces the metal plane of the right-angle frame 10 and directly contacts the inner wall of the housing 1. Most of the weight of the moving frame 6 and the friction generated during movement are borne by these rotating columns 12, avoiding direct hard scraping and wear between the right-angle frame 10 and the metal material of the inner wall of the housing 1. This effectively protects the inner wall of the housing 1 and the right-angle frame 10 itself, extends the service life of the key structure of the equipment, and reduces maintenance costs.
[0024] The working principle of a machining flaw detection device used in automobile steering knuckle production: In use, the operator or external automated equipment places the steering knuckle to be inspected onto the clamping fixture 4 and fixes it in place. Then, the sealing door 9 is closed, and the linear motor 2 starts, driving its slide and the robotic arm 3 mounted on it to move longitudinally along the bottom of the housing 1, initially delivering the steering knuckle to the inspection area below the flaw detector 5. The flaw detector 5 is activated, emitting inspection rays such as X-rays. Simultaneously, the robotic arm 3 can drive the clamping fixture 4 and the steering knuckle to perform multi-degree-of-freedom fine adjustments, such as rotation and fine-tuning positioning, ensuring that all parts of the steering knuckle to be inspected are completely scanned, achieving all-round non-destructive testing. After the inspection is completed, the linear motor 2 drives the robotic arm 3 to return the steering knuckle to its initial position. Then, the sealing door 9 is opened, and the operator or equipment removes it, completing one work cycle. When the operator controls the movement of the moving frame 6, causing relative displacement between the first support frame 701 on the moving frame 6 and the second support frame 702 fixedly mounted on the housing 1, the lead rubber curtain 703 connecting the two... As it is stretched or compressed, this design ensures that the lead rubber curtain 703 can always fill the gap between the moving frame 6 and the box 1, regardless of the position of the moving frame 6, thus preventing radiation from leaking out of the gap.
[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
