Description

Technical Field

[0001] This utility model relates to the field of air conditioner door panel measurement technology, specifically to a measuring fixture and an air conditioner. Background Technology

[0002] Because of their large size and long length, air conditioner door panels are prone to sickle-shaped deformation. After injection molding, sheet metal parts need to be assembled to increase the overall strength of the door assembly and control its overall deformation. Quality inspectors need to measure the deformation of the assembled door panel assembly to determine whether it is qualified. This avoids the situation where the entire unit is assembled but the gap is too large, resulting in a quality defect. This would require disassembling the unit and replacing the door panel, wasting manpower, material resources, and money. It also avoids the quality hazard of air conditioner panels entering the market due to excessive gaps, which could lead to customer complaints.

[0003] When measuring the deformation on both sides of the door panel assembly, the heights on both sides are different, making it impossible to place them on the platform for measurement simultaneously. Only the end without screws can be placed on the measuring platform, and the quality inspector can then use a feeler gauge to measure the deformation at this end. On the other hand, the end with screws cannot be measured because the screw heads are higher than the sheet metal of the door panel, and the plane of this end of the product cannot contact the platform. Furthermore, the end with screws is angled, requiring special tooling for accurate measurement.

[0004] In summary, measuring the deformation of door panel components is labor-intensive, inefficient, and prone to inaccurate measurements. It also carries the risk of waste due to the need to disassemble the machine and replace the door panels after assembly because of excessive gaps. Utility Model Content

[0005] To address the shortcomings of existing technologies, a measuring fixture and air conditioner are proposed. This solves the problems of high workload, low measurement efficiency, inaccurate measurement, and various waste risks associated with disassembling and reassembling the door panel after the entire machine is assembled due to excessive gaps.

[0006] To achieve the above objectives, the present invention proposes the following technologies:

[0007] A measuring fixture includes a fixture base for supporting a workpiece to be measured, wherein a limiting component is provided on the fixture base to limit the workpiece to be measured on the fixture base for easy measurement.

[0008] Furthermore, the limiting component includes protrusions that limit the length of the workpiece under test. The protrusions are located at both ends of the workpiece under test, and the workpiece under test is engaged between the protrusions on both sides of the tooling base.

[0009] Furthermore, the limiting component also includes a support seat located between the protrusions on both sides of the tooling base, the support seat abutting against the test piece to provide support and limiting for the test piece.

[0010] Furthermore, one end of the support base is provided with a step, the shape of which matches the edge shape of the part to be tested, so as to limit the width of the part to be tested.

[0011] Furthermore, one end of the tooling base is provided with a first reference surface, and the first reference surface and the workpiece to be tested form a first measurement position to facilitate the measurement of the deformation of the workpiece to be tested.

[0012] Furthermore, the tooling base has a clearance groove on the side away from the step, which is used to accommodate the screws on the edge of the workpiece to be tested so that the workpiece to be tested fits tightly with the support.

[0013] Furthermore, a second reference surface is provided on one side of the tooling base where the clearance groove is opened, and a second measuring position is formed between the second reference surface and the workpiece to be tested in order to measure the deformation of the workpiece to be tested.

[0014] Furthermore, the protrusion is slidably connected to the tooling base, and the protrusions at both ends of the tooling base slide along the length direction of the test piece to adjust the spacing and thus adapt to test pieces of different lengths.

[0015] Furthermore, the protrusion has a waist-shaped hole, which is set along the length of the workpiece to be measured. A fastening bolt is inserted into the waist-shaped hole, and the fastening bolt is threadedly connected to the tooling base.

[0016] Furthermore, the tooling base is provided with a sliding groove, which is arranged along the length direction of the workpiece to be measured. The bottom of the protrusion is provided with a slider that matches the sliding groove, and the slider slides in the sliding groove to guide and limit the protrusion.

[0017] Furthermore, the tooling base includes a limiting base and a measuring base. The limiting base is used to install the protrusion and there are two of them. The measuring base for supporting the workpiece to be measured is detachably connected between the two limiting bases.

[0018] Furthermore, the measuring base includes a first measuring base for supporting one end of the workpiece to be tested, and a second measuring base for supporting the other end of the workpiece to be tested, wherein the first measuring base and the second measuring base are detachably connected to the limiting base.

[0019] Furthermore, the part to be tested is a door panel assembly, which includes a plastic part and a sheet metal part assembled inside the plastic part. The first measuring base cooperates with the plastic part to facilitate the measurement of the deformation of the plastic part, and the second measuring base cooperates with the sheet metal part to facilitate the measurement of the deformation of the sheet metal part.

[0020] An air conditioner, wherein the deformation is measured using a measuring fixture as described in any of the above claims.

[0021] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0022] This application sets up a fixture base and a limiting component that match the part to be tested. The limiting component's limiting function fixes the part to be tested on the fixture base. By restricting the movement of the part in the length and width directions, and with the fixture base and part to be tested in close contact, measurement errors caused by improper placement during deformation measurement due to the movement of the part to be tested are avoided. This improves the accuracy of deformation measurement, prevents unqualified products from entering the market, and the measuring fixture can save measurement time, reduce the workload of quality inspectors, and achieve the goal of improving measurement efficiency.

[0038] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to 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.

[0040] Example 1:

[0041] like Figures 1 to 10 As shown, a measuring fixture includes a fixture base 2 for supporting a workpiece 1 to be measured. The fixture base 2 is provided with a limiting component to limit the workpiece 1 on the fixture base 2 for easy measurement.

[0042] By setting a fixture base 2 and a limiting component that match the part to be tested 1, the limiting component is used to fix the part to be tested 1 on the fixture base 2. By restricting the movement of the part to be tested 1 in the length and width directions, and by ensuring that the fixture base 2 fits tightly with the part to be tested 1, measurement errors caused by improper placement during the measurement of deformation due to the movement of the part to be tested 1 are avoided. This improves the accuracy of deformation measurement, prevents unqualified products from entering the market, and at the same time, the measuring fixture can save measurement time, reduce the workload of quality inspectors, and achieve the goal of improving measurement efficiency.

[0043] In the measuring fixture of this embodiment, the limiting component includes a protrusion 3 that limits the length of the workpiece 1 to be measured. The protrusion 3 is located at both ends of the workpiece 1 to be measured, and the workpiece 1 to be measured is snapped between the protrusions 3 on both sides of the fixture base 2.

[0044] Specifically, the protrusions 3 at both ends are set to fix the length direction of the test piece 1, restricting the longitudinal displacement of the test piece 1 on the tooling base 2, and avoiding relative movement between the test piece 1 and the tooling base 2, which would affect the measurement.

[0045] Preferably, a 2mm gap is left between the protrusion 3 and the left and right edges of the test piece 1, which not only limits the position but also prevents the test piece 1 from getting stuck with the fixture base 2, making it easy to remove the test piece 1 from the fixture base 2.

[0046] In a further preferred embodiment, the protrusion 3 is inclined on the side closest to the test piece 1 to form a guide surface with an inclination. The guide surface facilitates the placement of the test piece 1 and guides the test piece 1 to be inserted between the protrusions 3 at both ends to achieve a limit, which facilitates measurement.

[0047] The tooling base 2 is made of aluminum and has R5 chamfers at both ends. The human-shaped design serves as a guide, making it easier to reach in and hold the tooling for handling.

[0048] To avoid the tooling base 2 being too long and prone to deformation, which would reduce the accuracy of the guide measurement, preferably, the tooling base 2 can be provided with an assembly structure, divided into left and right parts. The bottom of the left part has an assembly groove, and the right part has an assembly block 9 that matches the assembly groove. The assembly is achieved by the assembly block 9 being snapped into the assembly groove and fixed with bolts.

[0049] In the measuring fixture of this embodiment, the limiting component also includes a support seat 4 located between the protrusions 3 on both sides of the fixture base 2. The support seat 4 abuts against the workpiece 1 to provide support and limit the workpiece 1.

[0050] Specifically, a support base 4 is set to support and limit the main body of the workpiece 1 to be tested. The shape of the surface of the support base 4 is consistent with the shape of the standard specification workpiece. Thus, by fitting the support base 4 with the workpiece 1 to be tested, the difference between the workpiece 1 to be tested and the standard specification, i.e., the amount of deformation, is reflected, so as to facilitate measurement. The support base 4 serves as a reference and works with the measuring tool to realize the measurement of the amount of deformation.

[0051] Preferably, the support base 4 and the tooling base 2 are both made of aluminum. This material is lightweight, sturdy, corrosion-resistant, and easy to process. Together with the tooling base 2, they form a tooling for measuring height difference deformation.

[0052] In the measuring fixture of this embodiment, one end of the support base 4 is provided with a step 5. The shape of the step 5 matches the edge shape of the workpiece 1 to be measured, so as to limit the width direction of the workpiece 1.

[0053] Specifically, step 5 matches the edge shape of the test piece 1. The test piece 1 is fitted outside step 5 to limit the width direction of the test piece 1 on the tooling base 2, thereby restricting the lateral displacement of the test piece 1 on the tooling base 2 and facilitating the measurement of the deformation on both sides of the width direction of the test piece 1.

[0054] In the measuring fixture of this embodiment, a first reference surface 6 is provided at one end of the fixture base 2, and a first measuring position is formed between the first reference surface 6 and the workpiece 1 to be measured so as to measure the deformation of the workpiece 1.

[0055] Specifically, the test part 1 is the door panel assembly, which includes plastic part 16. The plastic part 16 of the door panel refers to the appearance component product at the air outlet of the round cabinet air conditioner. The gap between it and other components is required to be small to avoid affecting the appearance quality. Therefore, the door panel assembly has strict requirements on the amount of deformation.

[0056] The edge of the plastic part 16 is bent, and the corresponding edge is located in the step 5 set on one side of the support base 4. The bottom surface of the step 5 is the first reference surface 6. The gap between the first reference surface 6 and the edge of the plastic part 16 is the first measurement position. The size of the gap reflects the amount of deformation of the plastic part 16. The amount of deformation of the first end of the door panel assembly is obtained by measuring the gap using a plug gauge.

[0057] Preferably, the plastic part 16 is made of ABS material, which has high impact resistance and can produce products with a high gloss finish.

[0058] In the measuring fixture of this embodiment, the fixture base 2 has an clearance groove 7 on the side away from the step 5. The clearance groove 7 is used to accommodate the screws on the edge of the workpiece 1 to be measured so that the workpiece 1 to be measured is tightly fitted with the support base 4.

[0059] Specifically, the test piece also includes a sheet metal part 17 assembled inside the plastic part 16. The purpose is to increase the overall strength of the door panel plastic part 16 assembly, control the deformation of the door panel assembly, and reduce the assembly gap with other parts. The edge of the plastic part 16 is bent and the width is greater than that of the sheet metal part 17. Therefore, the deformation of the plastic part 16 and the sheet metal part 17 is measured at both ends of the door panel assembly. The screws on the edge of the test piece 1 are used to connect the door panel sheet metal part 17 and the plastic part 16 to prevent the door panel sheet metal part 17 from shaking inside the door panel plastic part 16. In order to avoid the screw protruding from the surface of the sheet metal part 17 and affecting the measurement of the deformation of the sheet metal part 17, a relief groove 7 is opened on the tooling base 2 to accommodate the protruding screw, so that the screw is in a suspended state.

[0060] In the measuring fixture of this embodiment, a second reference surface 8 is provided on one side of the fixture base 2 where the clearance groove 7 is opened. The second reference surface 8 and the workpiece 1 to be measured form a second measuring position so as to measure the deformation of the workpiece 1 to be measured.

[0061] Specifically, the surface where the clearance groove 7 is made is the second reference surface 8. The edge of the sheet metal part 17 of the standard door panel assembly is flush with the surface of the clearance groove 7. The gap between the edge of the sheet metal part 17 and the surface of the clearance groove 7 is the second measurement position. The deformation of the other end of the door panel assembly can be obtained by measuring this gap using a plug gauge.

[0062] Preferably, the first reference surface 6 and the second reference surface 8 have a certain height difference to match the shape of the door panel assembly, thereby improving the fit between the tooling base 2 and the door panel assembly and improving the accuracy of deformation measurement.

[0063] In the measuring fixture of this embodiment, the protrusion 3 is slidably connected to the fixture base 2. The protrusions 3 at both ends of the fixture base 2 slide along the length direction of the workpiece 1 to adjust the spacing and thus adapt to workpieces 1 of different lengths.

[0064] By adjusting the spacing of the protrusions 3 on both sides, the test piece 1 of different lengths can be limited, thereby adapting to the deformation measurement of products of different lengths and sizes.

[0065] In the measuring fixture of this embodiment, the protrusion 3 has a waist-shaped hole 10, which is set along the length direction of the workpiece 1 to be measured. A fastening bolt 11 is inserted into the waist-shaped hole 10, and the fastening bolt 11 is threadedly connected to the fixture base 2.

[0066] Specifically, the fastening bolt 11 and the oblong hole 10 are matched at different positions to fix the protrusion 3, so as to realize the spacing adjustment and positioning of the protrusion 3 on both sides and ensure the limiting effect of the test piece 1.

[0067] In the measuring fixture of this embodiment, the fixture base 2 is provided with a sliding groove 12, the sliding groove 12 is arranged along the length direction of the workpiece 1 to be measured, and the bottom of the protrusion 3 is provided with a slider that matches the sliding groove 12. The slider slides in the sliding groove 12 to guide and limit the protrusion 3.

[0068] Specifically, a groove 12 is provided on the tooling base 2 to cooperate with the slider as a guide groove to guide the protrusion 3 to move in a straight line, so as to avoid the guide surface on the side of the protrusion 3 from being skewed.

[0069] Example 2:

[0070] In this embodiment of the measuring fixture, other settings adopt the same structure as in embodiment 1. Additionally, as... Figures 11 to 14 As shown, the tooling base 2 includes a limiting base 13 and a measuring base. The limiting base 13 is used to install the protrusion 3 and there are two of them. The measuring base for supporting the workpiece 1 is detachably connected between the two limiting bases 13.

[0071] Specifically, the limiting base 13 has two parallel sliding grooves that slide to connect the protrusions 3 respectively, so a total of four protrusions 3 are set at the four corners of the tooling base 2 to improve the limiting effect; the measuring base is provided with a support base 4, and the tooling base 2 is split structure by setting a detachable connecting measuring base and limiting base 13. The limiting base 13 is assembled with measuring bases of different lengths and shapes to limit and measure the deformation of door panel components of different sizes.

[0072] In the measuring fixture of this embodiment, the measuring base includes a first measuring base 14 for supporting one end of the workpiece 1 to be measured, and a second measuring base 15 for supporting the other end of the workpiece 1 to be measured. The first measuring base 14 and the second measuring base 15 are detachably connected to the limiting base 13.

[0073] Specifically, the measuring base is divided into a first measuring base 14 and a second measuring base 15, which measure the deformation on both sides of the door panel assembly respectively. Both are detachably connected to the limiting base 13. Different combinations of the first measuring base 14 and the second measuring base 15 can be made to adapt to the measurement of door panel assemblies of different shapes and specifications, thereby improving the adaptability of the tooling.

[0074] Specifically, the upper surfaces of the first measuring base 14 and the second measuring base 15 are respectively matched with the inner surface shape and contour of the door panel assembly to provide effective positioning and support for the door panel assembly. The inner side of the door panel assembly is arc-shaped, and the surfaces of the first measuring base 14 and the second measuring base 15 are in contact with the curvature of the two sides of the arc.

[0075] Preferably, the first measuring base 14 and the second measuring base 15 are respectively provided with plug connectors at both ends, and the limiting base 13 is provided with plug holes. The plug connectors are inserted into the plug holes and locked with bolts to realize the assembly of the measuring base and the limiting base.

[0076] In the measuring fixture of this embodiment, the first measuring base 14 cooperates with the plastic part 16 to facilitate the measurement of the deformation of the plastic part 16, and the second measuring base 15 cooperates with the sheet metal part 17 to facilitate the measurement of the deformation of the sheet metal part 17.

[0077] Specifically, a step 5 is provided on the first measuring base 14 to form a first reference surface 6 to facilitate the measurement of the deformation of the edge of the plastic part 16. An avoidance groove 7 and a second reference surface 8 are provided on the second measuring base 15 to avoid the screws on the sheet metal part 17 and to facilitate the measurement of the deformation of the edge of the sheet metal part 17 by means of a plug gauge.

[0078] On the other hand, this application also proposes an air conditioner that uses a measuring fixture described in any of the above embodiments to measure deformation. It is foreseeable that the air conditioner in this application includes all the beneficial effects of the measuring fixture described in the above embodiments, which will not be repeated here.
