Description

Technical Field

[0001] This utility model belongs to the field of tooling equipment, and in particular relates to an auxiliary tooling for workpiece flaw detection. Background Technology

[0002] After the welding process is completed, each weld seam of the conduits (workpieces) used in rocket engines needs to be X-rayed to check the reliability of the weld. When X-raying the weld seams, each seam needs to be photographed from different angles. Because these conduits are numerous, complex in shape, and mostly irregular in form, varying in size, length, and shape, it is difficult to position them correctly using a method of stacking them at a certain point to achieve the desired angle or position, hindering the smooth operation of the X-ray process. The disadvantages of this method are: 1. Cumbersome and inefficient; 2. Low safety factor, prone to tipping over if improperly placed. Therefore, a safe, reliable, and easy-to-operate auxiliary device needs to be designed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a workpiece flaw detection auxiliary tooling that is simple in structure, easy to use, and flexible in reversing direction.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A workpiece flaw detection auxiliary tooling includes a base, a movable arm, and a clamping component. One end of the movable arm is connected to the base, and the clamping component is disposed at the other end of the movable arm. The clamping component is used to clamp the workpiece, and the movable arm is a bendable shaping arm.

[0005] The beneficial effects of the above technical solution are as follows: the workpiece can be clamped by the clamping component, and then the shape of the movable arm can be adjusted to place the workpiece at the position of the X-ray machine detection unit. Then, the person can move away and turn on the X-ray machine to perform flaw detection on the workpiece.

[0006] The movable arm described in the above technical solution includes three arm bodies and three joint components. The three arm bodies are arranged sequentially, and adjacent two arm bodies are connected by a joint component. One of the outer arm bodies is connected to the base, and the clamping component is installed on another outer arm body through the remaining joint component.

[0007] The beneficial effect of the above technical solution is that the entire workpiece flaw detection auxiliary tooling requires three movable joints, that is, each joint component corresponds to one movable joint, and each movable joint has three degrees of freedom. At this time, the entire workpiece flaw detection auxiliary tooling can flexibly adjust the position of the workpiece in space.

[0008] In the above technical solution, the three arms are a first arm, a second arm, and a third arm. One end of the first arm is connected to the base. The other end of the first arm and one end of the second arm are connected by a joint. The other end of the second arm is connected to one end of the third arm by a joint.

[0010] The joint component described in the above technical solution includes a hinge, two lead screws, and two locking nuts. The hinge includes a hinge seat and a hinge ear, which are rotatably connected. Under external force, they can rotate relative to each other and be limited within any rotation angle range. One lead screw is connected to the hinge seat, and the other lead screw is connected to the hinge ear. The two locking nuts correspond one-to-one with the two lead screws and are threaded onto the corresponding lead screws. The lead screws are used to rotatably connect with the corresponding arm or clamping component. The lead screws rotate relative to the arm or clamping component to adjust the angle. Tightening the locking nuts until they abut against the arm or clamping component locks the connection between the corresponding lead screw and the arm or clamping component, or loosening the locking nuts releases the lock.

[0011] The beneficial effects of the above technical solution are: its structure is simple, and the lead screw is rotatably connected to the corresponding rod or clamping component, which allows the lead screw and the corresponding rod or clamping component to rotate flexibly.

[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0031] like Figure 1 As shown, this embodiment provides a workpiece flaw detection auxiliary fixture, including a base 1, a movable arm 2, and a clamping member 3. One end of the movable arm 2 is connected to the base 1, and the clamping member 3 is disposed at the other end of the movable arm 2. The clamping member 3 is used to clamp the workpiece. The movable arm 2 is a bendable and shape-fixing arm, so that the workpiece can be clamped by the clamping member. Then, by adjusting the shape of the movable arm, the workpiece can be placed at the position of the X-ray machine detection unit. Then, a person can move away and turn on the X-ray machine to perform flaw detection on the workpiece.

[0032] like Figure 1 and Figure 3 As shown, the movable arm 2 in the above technical solution includes three arm bodies 21 and three joints 22. The three arm bodies 21 are arranged sequentially, and adjacent two arm bodies 21 are connected by a joint 22. One of the arm bodies 21 located on the outer side is connected to the base 1. The clamping member 3 is installed on another arm body 21 located on the outer side through the remaining joint 22. In this way, the entire workpiece flaw detection auxiliary tooling requires three movable joints, that is, each joint corresponds to one movable joint, and each movable joint has three degrees of freedom. At this time, the entire workpiece flaw detection auxiliary tooling can flexibly adjust the position of the workpiece in space.

[0033] like Figure 2As shown, the base 1 in the above technical solution includes a base plate 11 and a plurality of casters 12 disposed at the lower end of the base plate 11, which makes the entire workpiece flaw detection auxiliary tooling move more flexibly; wherein at least one of the casters 12 is a brakeable caster, which allows the workpiece flaw detection auxiliary tooling to brake and stop after moving to the target position.

[0034] like Figure 1 and Figure 3 As shown, in the above technical solution, the three arms 21 are the first arm 211, the second arm 212, and the third arm 213. One end of the first arm 211 is connected to the base 1. The other end of the first arm 211 and one end of the second arm 212 are connected by a joint 22. The other end of the second arm 212 is connected to one end of the third arm 213 by a joint 22. The other end of the third arm 213 is connected to the clamping member 3 by the remaining joint 22. This allows the two adjacent arms to move flexibly, and the clamping member and the corresponding arm to move flexibly as well.

[0035] like Figure 3 As shown, the joint component 22 in the above technical solution includes a hinge component 221, two lead screws 222, and two locking nuts 223. The hinge component 221 includes a hinge seat 2211 and a hinge ear 2212. The hinge seat 2211 and the hinge ear 2212 are rotatably connected, and the two can rotate relative to each other under the action of external force and be limited within any rotation angle range. One lead screw 222 is connected to the hinge seat 2211, and the other lead screw 222 is connected to the hinge ear 2212. The two locking nuts 223 correspond one-to-one with the two lead screws 222 and are threaded onto the corresponding lead screw 222. 22 is used to rotatably connect with the corresponding arm body 21 or clamping member 3. The lead screw 222 rotates relative to the arm body 21 or clamping member 3 to adjust the angle. Tighten the locking nut 223 until it abuts against the arm body 21 or clamping member 3 to lock the connection between the lead screw 222 and the arm body 21 or clamping member 3, or loosen the locking nut 223 to release the lock. Its structure is simple, and the lead screw is rotatably connected with the corresponding rod body or clamping member, so that the lead screw and the corresponding rod body or clamping member can rotate flexibly. After tightening the locking nut, the rotatable connection between the lead screw and the rod body or clamping member can be locked, thereby maintaining the specific shape of the movable joint.

[0036] In this embodiment, the length of the first arm is approximately 5-10cm, and the lengths of the second and third arms are both 20-100m.

[0037] like Figure 5As shown, the hinge seat 2211 in the above technical solution is U-shaped. One end of the hinge ear 2212 extends into the hinge seat 2211 and is rotatably connected to the hinge seat 2211. One of the lead screws 222 is connected to the side of the hinge seat 2211 away from the slot, and the other lead screw 222 is connected to the end of the hinge ear 2212 located outside the hinge seat 2211. Its structure is simple and allows the hinge ear and the hinge seat to rotate under the action of external force, and to remain in position after the external force is removed.

[0038] like Figure 3 As shown, the hinge 221 in the above technical solution further includes a clamping bolt 2213 and a clamping nut 2214. The groove walls on both sides of the hinge seat 2211 are respectively provided with first through holes 22111, and the hinge ear 2212 is provided with a second through hole 22121. The second through hole 22121 is coaxial with the two first through holes 22111 and the clamping bolt 2213 is inserted into it. The clamping nut 2214 is threaded to the other end of the clamping bolt 2213. Tightening the clamping nut 2214 allows the hinge ear 2212 to be clamped by the hinge seat 2211, or loosening the clamping nut 2214 allows the hinge ear 2212 to be released by the hinge seat 2211. Its structure is simple. In this way, the clamping nut can be loosened so that the hinge seat and the hinge ear can rotate flexibly, while tightening the clamping nut can limit the position between the hinge seat and the hinge ear.

[0039] The clamping nut 2214 described in the above technical solution is a Torx nut, so the clamping nut can be turned manually.

[0040] like Figure 4 As shown, the clamping member 3 in the above technical solution is a clamp, which allows for convenient clamping of the workpiece and exposes the welded parts of the workpiece for X-ray inspection. Specifically, the clamping member includes a first clamp plate 31, a second clamp plate 32, and a bolted connector 33 (the bolted connector may include bolts and nuts). One end of the first clamp plate 31 and the second clamp plate 32 are rotatably connected, and the other end of the first clamp plate 31 and the second clamp plate 32 are detachably connected through the bolted connector 33. The side of the first clamp plate 31 facing away from the second clamp plate 32 is rotatably connected to the corresponding lead screw 222. The clamping member 3 in this embodiment is prior art and will not be described in detail here.

[0041] Taking the lead screw rotatably connected to the first arm body as an example, it has a locking nut 223. Loosening the locking nut 223 allows the lead screw to rotate relative to the first arm body, while tightening the locking nut makes it abut against the first arm body, thus locking the lead screw to the first arm body.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
