Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a tooling fixture for detecting the surface roughness of automotive parts. Background Technology

[0002] Automotive parts are the various units that make up the entire automotive parts processing system and the products that serve this process. By establishing R&D centers, parts manufacturers can achieve several advantages: speed – quickly meeting urgent market demands and rapidly developing products; accuracy – staying close to the market and achieving localization; and innovation – applying more new technologies to production, ensuring quality while reducing costs. In fact, some parts manufacturers are leading the way in developing new technologies for vehicle manufacturers. To reduce costs and capture market share, many multinational automotive parts companies are expanding internationally.

[0003] After automotive parts are manufactured, their surface roughness is usually tested. During the testing process, in order to ensure the stability of the parts, tooling fixtures are usually needed to position them. However, existing positioning devices are generally quite complicated to operate and cannot achieve stable positioning of parts through simple operations, which causes some trouble. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology. By utilizing the opposite screw directions at both ends of the double-ended screw and the threaded connection between the two moving frames and the outer wall of the double-ended screw, the two moving frames can move relative to each other, so that the clamping plates on the two moving frames can contact the side wall of the part, thereby achieving the positioning of both sides of the part. This invention provides a tooling fixture for detecting the surface roughness of automotive parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixture for inspecting the surface roughness of automotive parts includes a base. Two symmetrically arranged through slots are formed on the upper end of the base. Two symmetrically arranged movable frames are slidably connected between the two through slots. Two symmetrically arranged through rods are slidably connected to each of the two movable frames. Each through rod has a clamping plate at its end. The clamping plates are elastically connected to the movable frames via springs. Both movable frames are U-shaped. Two symmetrically arranged through slots are formed on the upper end of the base. A slider is slidably connected within each of the two through slots. Positioning plates are provided on the opposite surfaces of the two sliders. A limiting mechanism is provided within the base to limit the movement of the two sliders. Moving mechanisms are provided on both sides of the base to move the two movable frames.

[0007] Preferably, the limiting mechanism includes a slide bar disposed on the inner wall of the front end of the base, the slide bar passing through the two sliders and slidably connected to them.

[0008] Preferably, the moving mechanism includes two symmetrically arranged double-ended screws that are rotatably connected between the two side walls of the base. The two ends of the double-ended screws have opposite thread directions, and the two moving frames are respectively located at the two ends of the two double-ended screws and are threadedly connected to them.

[0009] Preferably, each of the two moving frames has two symmetrically arranged rotating seats on its opposite sides, and each of the two slider sidewalls has a connecting seat. Both rotating seats on the same side are rotatably connected to the connecting seats through a rotating plate.

[0010] Preferably, both of the two double-ended screws are provided with synchronous pulleys on their outer walls, and the two synchronous pulleys are connected by a synchronous belt drive.

[0011] Preferably, one of the double-headed screws has a knob at its end, and the outer wall of the knob has anti-slip texture.

[0012] The beneficial effects of this utility model are:

[0013] 1. By utilizing the opposite directions of the threads at both ends of the double-ended screw and the threaded connection between the two moving frames and the outer wall of the double-ended screw, the two moving frames can move relative to each other, so that the clamps on the two moving frames contact the side wall of the part, thereby achieving the positioning of both sides of the part.

[0014] 2. By changing the angle of multiple rotating plates, the multiple rotating plates push the two positioning plates to move, so that the two positioning plates contact the front and rear ends of the parts, thereby achieving stable clamping of the parts. The operation is convenient and brings certain convenience to people. Attached Figure Description

[0019] 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.

[0020] 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.

[0021] Reference Figure 1-3 A surface roughness inspection fixture for automotive parts includes a base 1. Two symmetrically arranged through slots 2 are formed at the upper end of the base 1. Two symmetrically arranged movable frames 7 are slidably connected between the two through slots 2. Two symmetrically arranged through rods 8 are slidably connected to each of the movable frames 7. Each of the through rods 8 has a clamping plate 9 at its end. The clamping plate 9 is elastically connected to the movable frame 7 by a spring 10. Both movable frames 7 are U-shaped. Two symmetrically arranged through slots 3 are formed at the upper end of the base 1. Slider 5 is slidably connected within each of the two through slots 3. Positioning plates 6 are provided on the opposite surfaces of the two sliders 5. A limiting mechanism for limiting the movement of the two sliders 5 is provided inside the base 1. The limiting mechanism includes a sliding rod 4 located on the inner wall of the front end of the base 1. The sliding rod 4 passes through the two sliders 5 and is slidably connected to them.

[0022] The base 1 has a moving mechanism on both sides for moving the two moving frames 7. The moving mechanism includes two symmetrically arranged double-ended screws 14 that are rotatably connected between the two side walls of the base 1. The threads at both ends of the double-ended screws 14 have opposite directions. The two moving frames 7 are located at the two ends of the two double-ended screws 14 and are threadedly connected to them. By utilizing the opposite directions of the threads at both ends of the double-ended screws 14 and the threaded connection between the two moving frames 7 and the outer wall of the double-ended screws 14, the two moving frames 7 can move relative to each other, so that the clamps 9 on the two moving frames 7 contact the side walls of the parts, thereby achieving the positioning of the two sides of the parts.

[0023] Two symmetrically arranged rotating seats 11 are provided on the opposite sides of the two moving frames 7, and connecting seats 12 are provided on the side walls of the two sliders 5. The two rotating seats 11 on the same side are rotatably connected to the connecting seats 12 through rotating plates 13. By changing the angle of multiple rotating plates 13, the multiple rotating plates 13 push the two positioning plates 6 to move, so that the two positioning plates 6 contact the front and rear ends of the parts, thereby achieving stable clamping of the parts. The operation is convenient and brings certain convenience to people.

[0024] Both double-ended screws 14 have synchronous pulleys 15 on their outer walls, and the two synchronous pulleys 15 are connected by a synchronous belt drive.

[0025] One of the double-headed screws 14 has a knob at its end, and the outer wall of the knob has anti-slip texture.

[0026] When using this utility model, during the surface roughness inspection of automotive parts (this part is prior art, so the specific methods of roughness inspection are not described in detail in this figure), the parts are placed on the upper part of the base 1, and the knob is turned to make one of the double-ended screws 14 rotate. Under the transmission action of the synchronous pulley 15 and the synchronous belt between the two double-ended screws 14, the two double-ended screws 14 rotate synchronously. By using the opposite direction of the threads at both ends of the double-ended screws 14, and the threaded connection between the two moving frames 7 and the outer wall of the double-ended screws 14, the two moving frames 7 move relative to each other, so that the clamping plates 9 on the two moving frames 7 contact the side wall of the parts, thereby achieving the positioning of the two sides of the parts.

[0027] At the same time, by utilizing the rotational connection between the rotating seat 11 and the connecting seat 12 of the moving frame 7 and the slider 5, and the limiting effect of the slide rod 4 on the slider 5, the movement of the two moving frames 7 causes the angle of multiple rotating plates 13 to change, thereby causing the multiple rotating plates 13 to push the two positioning plates 6 to move, so that the two positioning plates 6 contact the front and rear ends of the parts, thereby achieving stable clamping of the parts, which is convenient to operate and brings certain convenience to people.

[0028] Through the through-sliding connection of the two through rods 8 between the clamping plate 9 and the moving frame 7, and under the elastic action of the spring 10, when the two clamping plates 9 are in contact with the parts, the two positioning plates 6 are not in contact with the parts. The through-sliding connection between the through rods 8 and the moving frame 7 allows the clamping plate 9 to have a certain amount of room to move. The reaction force of the spring 10 will act on the clamping plate 9 to ensure that the two clamping plates 9 and the positioning plates 6 stably clamp the parts.

[0029] 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.
