[0001] This utility model relates to the field of workpiece inspection technology, and in particular to a workpiece inspection fixture. Background Technology

[0002] During vehicle assembly, a rod-shaped workpiece is frequently used, such as... Figure 1 It consists of a rod body 1 and a fixing plate 101, which are integrally formed, and the two ends of the fixing plate 101 are arc surfaces 102.

[0003] Because it needs to be used in conjunction with other workpieces during the assembly process, there are high requirements for the width of the fixing plate 101 and whether the center of the arc surface 102 is collinear with the axis of the rod 1. Therefore, before the workpiece leaves the factory, it needs to be inspected using a special inspection fixture to check whether it meets the requirements.

[0004] However, the existing inspection fixtures have a relatively complex structure, requiring workers to perform complicated operations when inspecting the workpiece. This inconvenience greatly reduces inspection efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problem that the existing inspection fixtures have complex structures, requiring workers to perform complicated operations when inspecting the workpiece, which is not convenient enough. Therefore, a workpiece inspection fixture is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A workpiece inspection fixture includes a base, on which a placement groove and an insertion hole are respectively provided; one end of the placement groove is provided with a notch; the base is also provided with a rotating hole, which is located above the insertion hole.

[0008] Preferably, the two sides of the placement groove are designed as contact surfaces.

[0009] Preferably, the rotating hole and the insertion hole are collinear.

[0010] Preferably, the insertion hole is a through hole.

[0011] Preferably, both sides of the fixing plate can be attached to the bonding surface.

[0012] Preferably, the rod can be inserted into the insertion hole, and the arc surface can fit against the inner wall of the rotating hole.

[0013] Preferably, a connecting plate is fixedly connected to the side wall of the substrate.

[0014] Compared with the prior art, the present invention provides a workpiece inspection fixture, which has the following beneficial effects:

[0015] This workpiece inspection fixture features a simple structure with a placement slot, insertion hole, and rotation hole. During the inspection process, it is only necessary to check whether the workpiece's fixing plate can be inserted into the placement slot, whether the two flat surfaces are in contact with the mating surface, and whether the fixing plate can rotate circumferentially within the rotation hole. This allows for a simple and convenient operation and significantly improves inspection efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example:

[0026] The shape of the workpiece to be inspected, such as Figure 1 As shown, it consists of a rod body 1 and a fixing plate 101, which are integrally formed. The two ends of the fixing plate 101 are arc surfaces 102. The arc surfaces 102 at both ends share a common center. The other two surfaces of the fixing plate 101 are flat surfaces. The width of the fixing plate 101 is the distance between these two flat surfaces.

[0027] The arc surface 102 and the rod 1 need to be collinear.

[0028] like Figures 1-6 The workpiece inspection fixture proposed in this embodiment includes a base 2, on which a placement groove 3 and an insertion hole 4 are respectively provided; one end of the placement groove 3 is provided with a notch 302 to avoid interference with the rod 1; the base 2 is also provided with a rotating hole 401, which is located above the insertion hole 4, and the insertion hole 4 and the rotating hole 401 are interconnected; the rotating hole 401 and the insertion hole 4 are coaxial, and both the rotating hole 401 and the insertion hole 4 are circular rotating holes.

[0029] The two sides of the placement groove 3 are set as the contact surface 301. That is to say, the width of the fixing plate 101 is the same as the width of the placement groove 3, and the two sides of the fixing plate 101 can be contacted with the contact surface 301, that is, the two flat surfaces can be contacted with the contact surface 301.

[0030] The rod 1 can be inserted into the socket 4, and the arc surface 102 can fit against the inner wall of the rotating hole 401; the radius of the rotating hole 401 is 1-2 mm larger than the radius of the arc surface 102; the inner diameter of the socket 4 is 3-5 mm larger than the diameter of the rod 1, ensuring that the rod 1 can be smoothly inserted into the socket 4.

[0031] like Figures 2-3 When it is necessary to test the width of the fixing plate 101, which is the distance between the two flat surfaces, the rod 1 is placed into the notch 302, and the fixing plate 101 is moved into the placement groove 3. Check whether the fixing plate 101 can be inserted into the placement groove 3 and whether the two flat surfaces are in contact with the mating surface 301. If they can, it means that the width of the fixing plate 101 meets the requirements. Otherwise, it means that the fixing plate 101 does not meet the requirements and the workpiece is unqualified.

[0032] When it is necessary to check whether the center of the arc surface 102 is collinear with the axis of the rod 1, in other words, to check whether the workpiece is straight and whether the degree of curvature is within the specified range; at this time, such as Figures 5-6 Insert rod 1 into insertion hole 4. At this time, check whether the fixing plate 101 can be moved into the rotating hole 401. If not, it is directly judged as unqualified.

[0033] When the fixed plate 101 can be moved into the rotating hole 401, the entire workpiece is rotated in a circle by the rod 1 at the top of the fixed plate 101 to check whether the fixed plate 101 can rotate in a circle within the rotating hole 401. If it can, it means that the center of the arc surface 102 and the axis of the rod 1 are collinear, the workpiece is straight, meets the requirements, and is qualified; otherwise, it means that the workpiece is unqualified.

[0034] With the design of placement slot 3, insertion hole 4, and rotation hole 401, the structure is simple. During the inspection process, it is only necessary to check whether the fixing plate 101 of the workpiece can be inserted into the placement slot 3, whether the two flat surfaces are in contact with the mating surface 301, and whether the fixing plate 101 can rotate in a circle within the rotation hole 401. This will determine whether the workpiece meets the requirements. The operation is simple and convenient, and the inspection efficiency is greatly improved.

[0035] like Figure 6 The socket 4 is a through hole, meaning that the bottom of the socket 4 completely penetrates the base 2.

[0036] With the design of the insertion hole 4 as a through hole, when the rod body 1 is inserted into the insertion hole 4, the air in the insertion hole 4 can be quickly discharged from the bottom, which facilitates insertion.

[0037] Furthermore, the through-hole design of socket 4 has the following advantages:

[0038] When the workpiece being tested gets stuck in the insertion hole 4, the operator can insert a push pin from the bottom of the base 2 and then apply force to push the workpiece out.

[0039] A connecting plate 201 is fixedly connected to the side wall of the base 2. The base 2 can be fixedly connected to other objects, such as a workbench, through the connecting plate 201. When connected to the workbench, a hole needs to be reserved on the workbench for the base 2 to pass through, or there is a bracket on the workbench, and the connecting plate 201 is fixed on the bracket so that the bottom of the base 2 is suspended.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
