Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically a simulated sheet metal assembly testing fixture for door panels. Background Technology

[0002] In numerous industries such as automobile manufacturing and power distribution equipment manufacturing, the assembly quality of door panels is crucial. Taking the automotive industry as an example, the molding and assembly precision of car door panels affect the assembly of subsequent components, and consequently, the performance of the entire car door, such as its sealing performance and impact resistance. During the early stages of door panel product development, there is an urgent need for a tool that can provide data on the uniformity of sheet metal gaps and the amount of interference between components to ensure door panel assembly quality and reduce rework costs later. Utility Model Content

[0003] The purpose of this invention is to provide data on the gap between the door panel and sheet metal and the interference between components during the early stage of door panel product development, so as to ensure the assembly quality of the door panel and provide data support for product optimization.

[0004] A simulated sheet metal assembly and testing fixture for door panels, comprising:

[0005] Door panel test piece: It has a folded edge and several assembly holes at its edge, and a columnar protrusion next to the assembly holes. A sealing strip is embedded inside the folded edge.

[0006] Base: A contour assembly table is mounted on it; the contour assembly table is set according to the shape of the door panel test piece and is used for simulated sheet metal assembly.

[0007] Positioning block: Installed on the contour assembly table by screws, the positioning block is designed to correspond to the positions of the assembly holes and columnar protrusions, and is used to position the door panel test piece;

[0008] Clamping knob: Installed on the positioning block, used to clamp and fix the door panel test piece in conjunction with the positioning block.

[0009] As a preferred embodiment of this utility model, the positioning block has a circular hole corresponding to the columnar protrusion, and the contour assembly table has a second positioning groove corresponding to the circular hole. The columnar protrusion is fitted into the circular hole and the second positioning groove. Through this cooperation method, the door panel test piece can be accurately positioned at the columnar protrusion position, ensuring the reliability of the positioning.

[0010] As a preferred embodiment of this utility model, the positioning block is provided with a clamping hole at the position corresponding to the assembly hole. The clamping hole is gourd-shaped. A first positioning groove is provided below the clamping hole on the contour assembly table. The clamping knob fixes the door panel test piece through the assembly hole and the clamping hole. The gourd-shaped clamping hole design provides space for the operation of the clamping knob, which facilitates the fixation of the door panel test piece.

[0011] As a preferred embodiment of this utility model, the clamping knob includes a circular clamping piece, and the lower end of the circular clamping piece is fixedly connected to a waist-shaped clamping block through a connecting post. The waist-shaped clamping block passes downward through the assembly hole and the clamping hole and is placed in the first positioning groove. The waist-shaped clamping block clamps the door panel test piece by rotating and cooperating with the gourd-shaped clamping hole. This structural design makes the clamping operation more convenient and stable, and can reliably fix the door panel test piece on the contour assembly table.

[0012] As a preferred embodiment of this utility model, a handle is fixedly installed at the middle position of the upper end face of the circular clamping piece, and indicator arrows are symmetrically arranged on both sides of the handle. The direction of the indicator arrows is consistent with the length direction of the waist-shaped clamping block. The handle makes it easy for the operator to rotate the clamping knob, and the indicator arrows can intuitively show the direction of the waist-shaped clamping block, making it convenient for the operator to judge the clamping status.

[0013] As a preferred embodiment of this utility model, an annular rubber pad is fixedly installed on the lower end face of the circular clamping piece. The rubber pad can increase the friction between the circular clamping piece and the door panel test piece, prevent the clamping knob from loosening during use, and at the same time play a certain protective role for the door panel test piece, avoiding damage to it during the clamping process.

[0014] As a preferred embodiment of this utility model, the test fixture is formed by injection molding, which can ensure the forming accuracy of the fixture, facilitate mass production, and reduce production costs.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] This utility model's testing fixture can efficiently complete the initial trial assembly verification of batch parts. By conducting confirmation through the testing fixture (such as gaps, surface differences, hole positions, etc.), product defects can be directly exposed, guiding the modification direction of unqualified parts. The testing fixture can simulate the vehicle assembly effect, discovering problems in advance and reducing rework costs later. The fixture has a reasonable structural design, precise positioning, reliable clamping, and convenient operation, which can effectively improve the efficiency and accuracy of door panel assembly testing, providing strong support for the development and quality improvement of door panel products.

[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] Example 1

[0025] like Figures 1 to 5 As shown, a specific embodiment of the simulated sheet metal assembly and testing fixture for door panels according to this utility model includes:

[0026] Base 1, on which a contour assembly table 2 is installed, the contour assembly table 2 being set to correspond to the shape of the door panel test piece 4;

[0027] The door panel test piece 4 has a folded edge 403 and several assembly holes 401 at its edge. A columnar protrusion 402 is provided next to the assembly holes 401. A sealing strip 3 is embedded inside the folded edge 403.

[0028] The positioning block 5 is installed on the contour assembly table 2 by screws 7. The positioning block 5 has a round hole 9 corresponding to the columnar protrusion 402. The contour assembly table 2 has a second positioning groove 11 corresponding to the round hole 9. The columnar protrusion 402 is sleeved in the round hole 9 and the second positioning groove 11 to realize the positioning of the door panel test piece 4 at the position of the columnar protrusion 402.

[0029] A gourd-shaped clamping hole 8 is provided on the positioning block 5 at the position corresponding to the assembly hole 401. A first positioning groove 10 is provided on the contour assembly table 2 below the clamping hole 8. The clamping knob 6 is installed on the positioning block 5.

[0030] The clamping knob 6 includes a circular clamping piece 601. The lower end of the circular clamping piece 601 is fixedly connected to a waist-shaped clamping block 604 via a connecting post 603. The waist-shaped clamping block 604 passes downward through the assembly hole 401 and the clamping hole 8 and is placed in the first positioning groove 10. A handle 606 is fixedly installed at the middle position of the upper end face of the circular clamping piece 601. Indicating arrows 605 are symmetrically arranged on both sides of the handle 606. The direction of the indicating arrows 605 is consistent with the length direction of the waist-shaped clamping block 604. An annular rubber pad 602 is fixedly installed on the lower end face of the circular clamping piece 601.

[0031] Preferably, the test fixture is formed by injection molding, which ensures the forming accuracy of the fixture, facilitates mass production, and reduces production costs.

[0032] The working principle of this utility model is as follows: When in use, the door panel test piece 4 is placed on the contour assembly table 2, so that the columnar protrusion 402 is inserted into the round hole 9 of the positioning block 5 and the second positioning groove 11 of the contour assembly table 2 to achieve preliminary positioning.

[0033] Then, the waist-shaped clamping block 604 of the clamping knob 6 passes through the assembly hole 401 and the clamping hole 8 and is placed in the first positioning groove 10. By rotating the handle 606, the waist-shaped clamping block 604 moves and clamps in the gourd-shaped clamping hole 8, thereby clamping and fixing the door panel test piece 4 on the contour assembly table.

[0034] Figure 5 The image shows the sealing strip in its natural state. However, during the measurement and evaluation process, the sealing strip 3 is deformed by the door panel test piece 4 and the contour assembly table 2, allowing for the measurement and evaluation of data such as gaps and interference.

[0035] The gap value can be checked manually using a gauge and visual inspection, specifically by measuring the gap between the edge of the door panel test piece and the contour assembly table.

[0036] All components mentioned in this article are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0037] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
