Description

Technical Field

[0001] This utility model belongs to the technical field of new energy vehicle horn frame technology, and in particular relates to a dual-station dimension inspection device for new energy vehicle horn frame. Background Technology

[0002] With the booming development of the new energy vehicle industry, the precision production and quality control of automotive parts have become key aspects of industry development. As an indispensable acoustic component of new energy vehicles, the dimensional accuracy of the speaker frame directly affects the speaker's installation compatibility and acoustic performance. Currently, most of the new energy vehicle speaker frame size inspection devices used in the industry are designed for a single specification of automotive speaker frame, and the layout of the inspection station is fixed to adapt to a specific size frame. In actual production scenarios, new energy vehicle manufacturers often equip speaker frames of various specifications according to the design requirements of different models.

[0003] However, the existing inspection equipment cannot meet the diverse testing needs. When different sizes of basin racks need to be tested, staff have to replace the entire testing equipment, which not only significantly increases the investment cost of the testing equipment, but also consumes a lot of time and manpower. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a dual-station size inspection device for the speaker frame of new energy vehicles. It solves the problem that the existing inspection device cannot meet the diverse testing needs. When it is necessary to inspect different specifications of speaker frames, the staff has to replace the entire testing device, which not only greatly increases the investment cost of the testing equipment, but also consumes a lot of time and manpower.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0006] A dual-station dimensional inspection device for horn frames of new energy vehicles includes a body. Four evenly distributed grooves are formed on one side of the upper wall of the body, and three evenly distributed grooves are formed on the other side of the upper wall. Movable blocks slide within the grooves. A detachable inspection column is mounted on the top surface of each movable block. A gantry frame is fixedly mounted on the top surface of the body. Two guide rods slide within the upper arm of the gantry frame. A pressure plate is fixedly mounted at the lower end of each guide rod. Two uprights are fixedly mounted on the top surface of the gantry frame. A scale is provided on the front of each upright. A pointer is fixedly mounted on one side of each guide rod, and the pointer matches the scale.

[0007] Furthermore, a lead screw is rotatably provided inside the slide groove, and the lead screw is threadedly connected to the movable block.

[0008] Furthermore, two through holes are provided on the upper wall of the machine body, one end of the lead screw passes through the through hole, and a driven bevel gear is fixedly provided on one end of the lead screw.

[0009] Furthermore, two fixed frames are fixedly provided on the bottom surface of the machine body, and a servo motor is fixedly provided on the fixed frame. The drive shaft of the servo motor is fixedly provided with an active bevel gear, one of which meshes with four driven bevel gears, and the other active bevel gear meshes with three driven bevel gears.

[0010] Furthermore, a handle is rotatably provided at the upper end of the guide rod.

[0011] Furthermore, a support block is fixedly provided on the top surface of the column, and the handle can be placed on the support block.

[0012] Furthermore, the top surface of the block is an arc-shaped surface.

[0013] Furthermore, the guide rod is fitted with a spring, which presses against the pressure plate.

[0014] Furthermore, the zero mark of the scale is located below the scale, and when the bottom surface of the pressure plate is flush with the top surface of the movable block, the pointer points to the zero mark of the scale.

[0015] The beneficial effects of this utility model are:

[0016] 1. By adjusting the position of the detection posts, the mounting holes of speaker frames of different specifications can be checked. Insert the three circumferentially distributed detection posts into the mounting holes of the speaker frame with three mounting holes, and insert the four circumferentially distributed detection posts into the mounting holes of the speaker frame with four mounting holes. If they can be inserted without gaps, it means that the size and position of the mounting holes of the speaker frame are accurate. If they cannot be inserted or are loose after being inserted, it means that the size and position of the mounting holes of the speaker frame are inaccurate. This realizes the checking of the position of the mounting holes of the speaker frame.

[0017] 2. The downward pressure applied to the pressure plate by the spring can press the bottom surface of the pressure plate tightly against the top surface of the speaker frame. At this time, the pointer points to the scale value of the speaker frame, thus realizing the inspection of the thickness of the speaker frame. Attached Figure Description

[0025] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-6 As shown, this utility model provides a dual-station dimension inspection device for horn frames of new energy vehicles, including a body 1. Four evenly distributed grooves 5 are formed on one side of the upper wall of the body 1, and three evenly distributed grooves 5 are formed on the other side of the upper wall of the body 1. Movable blocks 3 slide within the grooves 5. A detachable inspection column 4 is mounted on the top surface of the movable block 3. A gantry frame 6 is fixedly mounted on the top surface of the body 1. Two guide rods 8 slide within the upper arm of the gantry frame 6. A pressure plate 7 is fixedly mounted at the lower end of the guide rods 8. Two columns 12 are fixedly mounted on the top surface of the gantry frame 6. A scale 14 is provided on the front of the column 12. A pointer 13 is fixedly mounted on one side of the guide rod 8, and the pointer 13 matches the scale 14. A lead screw 2 rotatably rotates within the grooves 5, and the lead screw 2 is threadedly connected to the movable block 3. Two through holes 20 are formed on the upper wall of the body 1. 2 One end of the screw rod 2 passes through the through hole 20, and a driven bevel gear 16 is fixedly installed at one end of the screw rod 2; two fixed brackets 18 are fixedly installed on the bottom surface of the machine body 1, and a servo motor 19 is fixedly installed on the fixed bracket 18. The drive shaft of the servo motor 19 is fixedly installed with a drive bevel gear 17. One drive bevel gear 17 meshes with four driven bevel gears 16, and the other drive bevel gear 17 meshes with three driven bevel gears 16; a handle 9 is rotatably installed at the upper end of the guide rod 8; a block 10 is fixedly installed on the top surface of the column 12, and the handle 9 can rest on the block 10; the top surface of the block 10 is an arc surface 11; a spring 15 is sleeved on the guide rod 8, and the spring 15 presses against the pressure plate 7; the zero mark value of the scale 14 is located below the scale 14. When the bottom surface of the pressure plate 7 is flush with the top surface of the movable block 3, the pointer 13 points to the zero mark value of the scale 14.

[0027] In use, starting the servo motor 19 causes the drive bevel gear 17 to rotate. The rotation of the drive bevel gear 17 causes multiple driven bevel gears 16 to rotate. The rotation of the multiple driven bevel gears 16 causes multiple lead screws 2 to rotate. The rotation of the multiple lead screws 2 causes multiple movable blocks 3 to move. The movement of the multiple movable blocks 3 causes multiple detection posts 4 to move. By adjusting the position of the detection posts 4, the mounting holes of different specifications of speaker frames can be checked. Three circumferentially distributed detection posts 4 are inserted into the mounting holes of the speaker frame 31 with three mounting holes, and four circumferentially distributed detection posts 4 are inserted into the mounting holes of the speaker frame 31 with four mounting holes. If the speaker can be inserted into the mounting hole 0 without any gap, it indicates that the mounting hole size and position of the speaker frame are accurate. If it cannot be inserted or is loose after insertion, it indicates that the mounting hole size and position of the speaker frame are inaccurate. This allows for the inspection of the mounting hole position of the speaker frame. Rotating the handle 9 disengages it from the mounting block 10. Pressing the handle 9 downwards allows the bottom surface of the pressure plate 7 to contact the top surface of the speaker frame. The downward pressure applied to the pressure plate 7 by the spring 15 presses the bottom surface of the pressure plate 7 tightly against the top surface of the speaker frame. At this time, the pointer 13 points to the scale value of the scale 14, which is the thickness of the speaker frame. This allows for the inspection of the thickness of the speaker frame.
