Description

Technical Field

[0001] This utility model relates to the field of inspection tools, specifically to a tooling for inspecting the flatness of an automobile cover. Background Technology

[0002] The car cover is a type of automotive connector. The cover has a central opening and a tapered surface between its upper and lower ends. The flatness of the car cover directly affects the assembly accuracy and appearance quality. Therefore, after the car cover is produced, its upper surface needs to be inspected for flatness.

[0003] Traditional flatness inspection methods often use fixed gauges or handheld measuring tools, which have low accuracy. However, car covers come in various sizes and specifications, with different diameters and heights. General flatness gauges cannot be adjusted according to the specifications of the car covers, so a new type of tooling for inspecting the flatness of car covers is needed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for inspecting the flatness of an automotive cover, comprising a base plate, on which a three-jaw chuck and a rotating shaft are coaxially arranged, the rotating shaft being rotatably connected to the base plate, a positioning component being fixedly connected to the jaws of the three-jaw chuck, an adjusting lifting plate being slidably connected to the rotating shaft, a plurality of adjusting holes being opened at the end of the adjusting lifting plate, a transverse pull plate being slidably connected to the adjusting lifting plate, a fine adjusting screw and a ball-head plunger being threadedly connected to the transverse pull plate, and a detection rod being fixedly connected to the lower end of the fine adjusting screw passing through the transverse pull plate.

[0006] Furthermore, the positioning component includes a positioning plate and a positioning pin, wherein the positioning pin is fixedly connected to the positioning plate.

[0007] Furthermore, the base plate is detachably connected to multiple pads, which are offset from the positioning component.

[0008] Furthermore, both the rotating shaft and the fine adjustment screw are provided with anti-slip textures, and the adjusting lifting plate is fixedly connected to the rotating shaft by a bolt assembly.

[0009] Furthermore, the transverse pull plate is slidably connected to the end of the adjusting lifting plate with the adjusting hole, and the ball of the ball plunger is correspondingly set with the adjusting hole.

[0010] Furthermore, a ball bearing is rotatably connected to the lower end of the detection rod.

[0011] The beneficial effects of this utility model are as follows: the three-jaw chuck can simultaneously adjust the distance between multiple positioning components and the rotating shaft, adapting to the positioning of flatness detection of car covers of different specifications, and the positioning adjustment operation is convenient.

[0012] Equipped with an adjustable lifting plate that works in conjunction with a horizontal pull-out plate, the system facilitates convenient adjustment and testing, provides high testing accuracy, and makes loading and unloading of automotive body panels easy. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0019] Example:

[0020] refer to Figures 1-3 The illustrated automotive cover flatness inspection fixture includes a base plate 1, on which a three-jaw chuck 2 and a rotating shaft 3 are coaxially mounted. The rotating shaft 3 is rotatably connected to the base plate 1. A positioning component is fixedly connected to the jaws of the three-jaw chuck 2. An adjusting lifting plate 5 is slidably connected to the rotating shaft 3. Multiple adjusting holes 501 are opened at the end of the adjusting lifting plate 5. A transverse pull plate 6 is slidably connected to the adjusting lifting plate 5. A fine adjustment screw 7 and a ball plunger 10 are threadedly connected to the transverse pull plate 6. A detection rod 8 is fixedly connected to the lower end of the fine adjustment screw 7 through the transverse pull plate 6.

[0021] The positioning assembly includes a positioning plate 401 and a positioning pin 402. The positioning plate 401 is used to position the annular outer wall at the lower end of the car cover, and the positioning pin 402 is used to match the through hole at the lower end of the car cover for positioning, preventing the car cover from deflecting during testing. The positioning pin 402 is fixedly connected to the positioning plate 401. A plurality of pads 9 are detachably connected to the base plate 1, and the pads 9 are used to support and place the car cover.

[0022] Both the rotating shaft 3 and the fine adjustment screw 7 are provided with anti-slip textures to facilitate the rotation of the rotating shaft 3 and the fine adjustment screw. The adjusting lifting plate 5 is fixedly connected to the rotating shaft 3 by a bolt assembly. When the bolt assembly is loosened, the adjusting lifting plate 5 can be raised and lowered to perform adjustment.

[0023] The transverse pull-out plate 6 is slidably connected to one end of the adjusting lifting plate 5 with the adjusting hole 501. When the transverse pull-out plate 5 is pulled out, the ball of the ball plunger 10 can be engaged in the adjusting hole 501 to achieve positioning of the transverse pull-out plate 6. The lower end of the detection rod 8 is rotatably connected to a ball 801 to prevent damage to the upper surface of the car cover during flatness testing.

[0024] The working principle of this utility model is as follows: Before use, adjust the position of the positioning component according to the diameter of the bottom of the car cover. By rotating the input end of the three-jaw chuck 2, the three jaws of the three-jaw chuck 2 are simultaneously moved closer to or away from the center, thereby realizing the position adjustment of the positioning component. Then, adjust the height of the adjusting lifting plate 5. By loosening the bolt assembly, the height of the adjusting lifting plate 5 can be coarsely adjusted by sliding it up and down. The height of the detection rod 8 can be finely adjusted by rotating the fine adjusting screw 7.

[0025] When conducting the test, refer to Figure 4 First, position the car cover along the positioning plate 401 and positioning pin 402. Then, pull the horizontal pull plate 6 outward to make the ball bearing 801 fit against the upper surface of the car cover. Next, rotate the rotating shaft 3 to make the ball bearing at the lower end of the detection rod 8 sweep against the upper surface of the car cover. If the detection rod 8 can rotate normally more than one revolution, the flatness test is qualified; otherwise, it is unqualified. After the test is completed, push the horizontal pull plate 6 inward and remove the car cover directly upward.

[0026] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
