Description

Technical Field

[0001] This utility model relates to the field of testing tooling, specifically a testing fixture for an automotive display screen mounting bracket. Background Technology

[0002] The automotive display screen mounting bracket is a structural component used to mount the display screen on new energy vehicles. This component is an injection-molded part with an internal cavity, and the partition has transverse holes that communicate with the cavity. To ensure the product's dimensions, it is necessary to inspect the outer edge and flatness of the product. Existing display screen mounting brackets, when used for inspection, do not employ equipment that can quickly fix the product during inspection. Instead, they rely on quick-clamp mechanisms to hold the product, which requires supporting the product and causes interference with the outer edge, hindering the measurement of the outer edge dimensions. Furthermore, due to the large size and weight of the display screen mounting bracket, it is difficult to position and clamp it securely using quick-clamp mechanisms.

[0003] Therefore, it is necessary to provide a vehicle display mounting bracket inspection tool. Utility Model Content

[0004] This utility model provides an automotive display screen mounting bracket inspection tool, which effectively solves the problem that existing equipment is not conducive to dimensional inspection of the outer edge of the product.

[0005] The technical solution adopted in this utility model is:

[0006] The automotive display screen mounting fixture includes a frame and a gap detection component mounted on the frame. It also includes a support base mounted on the frame, a lower positioning post mounted on the support base, a left arc-shaped positioning post and a right arc-shaped positioning post symmetrically mounted on the support base, a lower insertion positioning component mounted on the support base, and several mounting components mounted on the support base. The lower positioning post, the left arc-shaped positioning post, and the right arc-shaped positioning post all form a gap with the outer edge of the product. The mounting components include a first connecting plate mounted on the support base and several rotating clamping components mounted on the first connecting plate.

[0007] Furthermore, the first connecting plate is provided with a through hole, and the rotating clamping component includes a screw that is slidably connected to the through hole, a waist-shaped block fixedly disposed at one end of the screw, a handheld end fixedly disposed at the other end of the screw, and a nut that is threadedly connected to the screw. The nut is located between the handheld end and the first connecting plate.

[0008] Furthermore, both the left and right arc-shaped positioning posts are provided with several positioning blocks. The frame is also provided with a flatness testing component and a support block for placing the flatness testing component. The flatness testing component includes a pin, a mounting block, and a dial indicator set on the mounting block. The pin is set on the mounting block. The support block is provided with a first insertion hole for the pin to engage. The positioning block is provided with a second hole for engaging with the pin.

[0009] Furthermore, the lower insertion positioning component includes a second connecting plate mounted on the support base, a rotating plate hinged to the second connecting plate, an insertion block, and a positioning rod. The rotating plate is provided with a sliding groove that is slidably connected to the insertion block and a guide hole that communicates with the sliding groove for slidably connecting to the positioning rod. The insertion block is provided with a first positioning hole and a second positioning hole in sequence along its length direction. The positioning rod passes through the guide hole and extends into the first or second positioning hole.

[0010] Furthermore, the lower insertion positioning component also includes a knob bolt, and the second connecting plate is provided with a screw hole. The knob bolt is set on the rotating plate for threaded connection with the screw hole to fix the rotating plate and the second connecting plate.

[0011] Furthermore, the lower insertion positioning component also includes a limiting protrusion disposed on the insertion block, the limiting protrusion being used to restrict the lower insertion positioning plate from sliding down the slide groove.

[0012] Furthermore, the gap detection component includes a handle and two cylinders, a first cylinder and a second cylinder, respectively disposed at both ends of the handle. The diameter of the first cylinder is larger than the diameter of the second cylinder. If the first cylinder cannot be inserted into the gap and the second cylinder can pass through all gaps, it indicates that the gap size is qualified.

[0013] The beneficial effects of this utility model: The rotating clamping component, by penetrating deep into the product cavity and then rotating, achieves both positioning and pressing the product partition onto the first connecting plate, thus facilitating product fixation. Furthermore, the outer edge of the fixed product is exposed, making it convenient for dimensional inspection of the outer edge. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, the automotive display mounting bracket fixture provided in the embodiments of this application includes a frame 1 and a gap detection component 2 disposed on the frame 1. It also includes a support base 3 disposed on the frame 1, a lower positioning post 4 disposed on the support base 3, a left arc-shaped positioning post 5 and a right arc-shaped positioning post 6 symmetrically disposed on the support base 3, a lower insertion positioning component 7 disposed on the support base 3, and several mounting components 8 disposed on the support base 3. The lower positioning post 4, the left arc-shaped positioning post 5, and the right arc-shaped positioning post 6 all form a gap with the outer edge of the product 12. The mounting component 8 includes a first connecting plate 81 disposed on the support base 3 and several rotating clamping components disposed on the first connecting plate 81.

[0025] It should be noted that the partition 121 of product 12 has a partition 121, on which two transverse holes 120 are provided. The rotating clamping member can be inserted into the transverse holes 120 and rotated to clamp the partition 121 of product 12. Product 12 is provided with a positioning groove that cooperates with the lower insertion positioning member 7.

[0026] In actual use, the product 12 is fixed by the mounting component 8 and the lower insertion positioning component 7, so that gaps are formed between the product 12 and the lower positioning post 4, the left arc-shaped positioning post 5, and the right arc-shaped positioning post 6. The gaps are then detected by the gap detection component 2. When it is necessary to remove the product 12, the lower insertion positioning component 7 first disengages from the product 12, and then the rotating clamping component is rotated to disengage from the product 12.

[0027] In the above design, the rotating clamping component is inserted into the cavity of product 12 and then rotated. This not only achieves positioning but also presses the partition 121 of product 12 onto the first connecting plate 81. This facilitates the fixing of product 12, and the outer edge of product 12 is exposed after fixing, making it convenient to measure the size of the outer edge.

[0028] Specifically: such as Figure 3 As shown, the first connecting plate 81 is provided with a through hole, and the rotating clamping component includes a screw 82 slidably connected to the through hole, a waist-shaped block 83 fixedly disposed at one end of the screw 82, a handheld end 84 fixedly disposed at the other end of the screw 82, and a nut 85 threadedly connected to the screw 82. The nut 85 is located between the handheld end 84 and the first connecting plate 81.

[0029] In actual use, the waist-shaped block 83 is kept in a horizontal position to ensure that it corresponds to the horizontal hole 120. The nut 85 is screwed to one side of the hand-held end 84. One person holds the product 12, and another person pushes the screw 82 so that the waist-shaped block 83 passes through the horizontal hole 120 and extends into the cavity of the product 12. Then, the screw 82 is rotated so that the waist-shaped block 83 is kept in a vertical position. At this time, the waist-shaped block 83 and the vertical hole form a cross structure, so that the waist-shaped block 83 cannot pass through the horizontal hole 120. Then, the nut 85 is screwed away from the hand-held end 84 until one side of the nut 85 abuts against the first connecting plate 81. At this time, the waist-shaped block 83 presses the partition 121 of the product 12 onto the first connecting plate 81, thereby fixing the product 12.

[0030] In the above design, the structural design and specific implementation of the entire rotating clamping component facilitates insertion into the cavity of product 12 to clamp the partition 121 of product 12, thereby fixing product 12.

[0031] Specifically: such as Figure 1As shown, both the left arc-shaped positioning post 5 and the right arc-shaped positioning post 6 are provided with several positioning blocks 10. The frame 1 is also provided with a flatness detection component 9 and a support block 11 for placing the flatness detection component 9. Figure 7 As shown, the flatness testing component 9 includes a pin 91, a mounting block 92, and a dial indicator 93 disposed on the mounting block 92. The pin 91 is disposed on the mounting block 92. The support block 11 is provided with a first insertion hole for engaging with the pin 91. The positioning block 10 is provided with a second hole for engaging with the pin 91.

[0032] During actual testing, after the product 12 is fixed on the inspection fixture of this application, the dial indicator 93, along with the mounting block 92 and the pin 91, is removed from the support block 11. Then, the flatness testing piece 9 is sequentially matched with each positioning block 10 so that the flatness is measured at the corresponding position of the product 12 at each positioning block 10. By comparing whether the changes of the dial indicator 93 at each position are within the error range, if they are within the error range, it means that the flatness of the product 12 is qualified; otherwise, it is unqualified.

[0033] In the above design, the structural design and specific implementation of the flatness detection component 9 facilitate the detection of the flatness of the product 12.

[0034] Specifically: such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the lower positioning component 7 includes a second connecting plate 71 mounted on the support base 3, a rotating plate 72 hinged to the second connecting plate 71, an insert block 73, and a positioning rod 74. The rotating plate 72 is provided with a sliding groove that is slidably connected to the insert block 73 and a guide hole that communicates with the sliding groove for slidably connecting to the positioning rod 74. The insert block 73 is provided with a first positioning hole 701 and a second positioning hole 702 (located below the first positioning hole 701) in sequence along its length. The positioning rod 74 passes through the guide hole and extends into the first positioning hole 701 or the second positioning hole 702.

[0035] In actual use, before placing the product 12, the insert 73 is lifted up along the slide groove. Then, the positioning rod 74 cooperates with the second positioning hole 702 to limit the position of the insert 73. After the product 12 is pressed onto the first connecting plate 81 by the rotating clamping part, the positioning rod 74 is pulled out so that the insert 73 falls down along the slide groove and inserts into the positioning groove of the product 12. Then, the positioning rod 74 is reinserted into the guide hole to cooperate with the first positioning hole 701.

[0036] In the above design, the structural design and specific implementation of the lower positioning component 7 can effectively achieve the matching with the positioning groove of the product 12.

[0037] Specifically: such as Figure 4As shown, the lower insertion positioning component 7 also includes a knob bolt 75. The second connecting plate 71 is provided with a screw hole. The knob bolt 75 is provided on the rotating plate for threaded connection with the screw hole to fix the rotating plate and the second connecting plate 71.

[0038] In actual use, when product 12 needs to be removed, the lower positioning component 7 can be moved to avoid positioning product 12: after the positioning rod 74 is pulled upward, the positioning post engages with the second positioning hole 702, and the insert 73 disengages from product 12; loosen the knob bolt 75, and then rotate the rotating plate so that the entire insert 73 is located on the side of product 12. When product 12 needs to be positioned, first rotate the rotating plate so that the insert 73 is above the positioning groove, then pull out the positioning cover so that the insert 73 enters the positioning groove downward, then the positioning post engages with the first positioning hole 701, and then tighten the knob bolt 75.

[0039] In the above design, the structural design and specific implementation of the lower positioning component 7 can effectively achieve the avoidance of the product 12.

[0040] Specifically: such as Figure 4 As shown, the lower insertion positioning member 7 also includes a limiting protrusion 76 disposed on the insertion block 73, the limiting protrusion 76 being used to restrict the lower insertion positioning plate from sliding down the slide groove.

[0041] In actual use, the limiting protrusion 76 at the upper end of the insert 73 can abut against the upper edge of the slide groove.

[0042] In the above design, the limiting protrusion 76 can effectively prevent the insert block 73 from falling off along the slide groove during the rotation of the rotating plate.

[0043] Specifically: such as Figure 6 As shown, the gap detection component 2 includes a handle 21 and a first cylinder 22 and a second cylinder 23 respectively disposed at both ends of the handle 21. The diameter of the first cylinder 22 is larger than the diameter of the second cylinder 23. If the first cylinder 22 cannot be inserted into the gap and the second cylinder 23 can pass through all gaps, it indicates that the gap size is qualified. For example, if the product 12 is qualified in size, the gap range is 1.1cm to 1.2cm. Then, the diameter of the first cylinder 22 is greater than 1.2cm (1.3cm), and the diameter of the second cylinder 23 is less than 1.1cm.

[0044] In actual use, after the product 12 is fixed, hold the handle 21 of the gap detection piece 2 and first use the first cylinder 22 to perform the detection. If the first cylinder 22 can be inserted into the gap, it means that the gap size formed by the product 12 and the inspection tool exceeds the standard range. Then use the second cylinder 23 to perform the detection. If the second cylinder 23 is stuck at any point, it means that the gap size exceeds the standard range.

[0045] In the above design, the structural design and specific implementation of the gap detection component 2 can effectively detect the gap, thereby quickly determining whether the dimensions of the outer edge of the product 12 are qualified.

[0046] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
