Description

Technical Field

[0001] The invention relates to the technical field of air conditioner door panel measurement, and in particular to a measuring tool and an air conditioner. Background Art

[0002] Air-conditioning door panels are large in size and long in length, and are prone to sickle deformation. After injection molding, they need to be assembled with sheet metal parts to increase the overall strength of the door panel assembly and control its overall deformation. Quality inspectors need to measure the deformation of the door panel assembly assembled with sheet metal parts to determine whether it is qualified, so as to avoid the quality being judged as unqualified due to excessive gaps after the whole machine is assembled, and the machine is dismantled and reassembled with the door panel, which wastes manpower, material and financial resources, and also avoids quality risks that may flow to the market and lead to customer complaints due to excessive gaps.

[0003] When measuring the deformation on both sides of the door panel assembly, the heights of the two sides are different and cannot be placed on the platform for measurement simultaneously. Only the end without screws can be placed on the measuring platform, and the quality inspector uses a feeler gauge to measure the deformation of this end. The screw cap on the end with the screw is higher than the sheet metal of the door panel, resulting in the plane of this end of the product unable to contact the platform and cannot be measured. On the other hand, the end with the screw has an inclination, and special tooling is required for accurate measurement.

[0004] In summary, measuring the deformation of the door panel assembly is labor-intensive, with low measurement efficiency, and there is a risk of inadequate measurement. There is also a risk of waste due to disassembly and reassembly of the door panel after the whole machine is assembled due to excessive gaps. Summary of the invention

[0005] In view of the shortcomings of the existing technology, a measuring tool and air conditioner are proposed, which solves the problems of high labor intensity, low measurement efficiency, inadequate measurement, and various waste risks such as dismantling the machine and reassembling the door panel due to excessive gaps after the whole machine is assembled.

[0006] To achieve the above objectives, the present invention proposes the following technologies to achieve the above objectives: A measuring tool comprises a tool base for supporting a workpiece to be measured, wherein a limiting component is arranged on the tool base to limit the workpiece to be measured on the tool base for easy measurement.

[0007] Furthermore, the limiting assembly includes protrusions for limiting the length direction of the piece to be tested, the protrusions are located at both ends of the piece to be tested, and the piece to be tested is clamped between the protrusions on both sides of the tooling base.

[0008] Furthermore, the limiting assembly also includes a support seat located between the protrusions on both sides of the tooling base, and the support seat is against the workpiece to be tested to provide support and limiting for the workpiece to be tested.

[0009] Furthermore, a step is provided at one end of the support seat, and the shape of the step matches the edge shape of the workpiece to be tested so as to limit the width direction of the workpiece to be tested.

[0010] Furthermore, a first reference surface is provided at one end of the tooling base, and a first measuring position is formed between the first reference surface and the workpiece to be measured so as to measure the deformation of the workpiece to be measured.

[0011] Furthermore, a side of the tooling base away from the step is provided with an avoidance groove, and the avoidance groove is used to accommodate screws on the edge of the piece to be tested so that the piece to be tested fits tightly with the support seat.

[0012] Furthermore, a second reference surface is provided on one side of the tooling base where the avoidance groove is provided, and a second measuring position is formed between the second reference surface and the workpiece to be measured so as to measure the deformation of the workpiece to be measured.

[0013] Furthermore, the protrusions are slidably connected to the tooling base, and the protrusions at both ends of the tooling base slide along the length direction of the workpiece to be tested to adjust the spacing and thus adapt to workpieces to be tested of different lengths.

[0014] Furthermore, a waist-shaped hole is formed on the protrusion, and the waist-shaped hole is arranged along the length direction of the test piece. A fastening bolt is inserted into the waist-shaped hole, and the fastening bolt is threadedly connected to the tooling base.

[0015] Furthermore, a slide groove is provided on the tooling base, and the slide groove is arranged along the length direction of the workpiece to be tested. A slider matching the slide groove is provided at the bottom of the protrusion, and the slider slides in the slide groove to guide and limit the protrusion.

[0016] Furthermore, the tooling base includes a limiting base and a measuring base. The limiting base is used to install the protrusion and is provided with two. The measuring base for supporting the workpiece to be measured is detachably connected between the two limiting bases.

[0017] Furthermore, the measuring base includes a first measuring base for supporting one end of the workpiece to be measured, and a second measuring base for supporting the other end of the workpiece to be measured, and the first measuring base and the second measuring base are respectively detachably connected to the limiting base.

[0018] Furthermore, the part to be tested is a door panel assembly, which includes a plastic part and a sheet metal part assembled on the inside of 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.

[0019] An air conditioner uses any one of the above-mentioned measuring tools to measure deformation.

[0020] Compared with the prior art, the comprehensive effects brought by the present invention include: The present application sets a tooling base and a limit assembly that match the workpiece to be measured, and uses the limit function of the limit assembly to fix the workpiece to be measured on the tooling base. By limiting the movement of the workpiece to be measured in the length and width directions, and the tooling base fits tightly with the workpiece to be measured, measurement errors caused by improper placement during deformation measurement due to the movement of the workpiece to be measured can be avoided, the deformation measurement accuracy can be improved, and unqualified products can be prevented from entering the market. At the same time, the measuring tool can save measurement time, reduce the workload of quality inspectors, and achieve the purpose of improving measurement efficiency.

[0023] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present invention.

[0024] In this document, terms such as "upper", "lower", "left", "right", "top", etc. that indicate orientations or positional relationships are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0025] Embodiment 1: like Figures 1 to 10 As shown, a measuring tool comprises a tool base 2 for supporting a workpiece 1 to be measured, and a limiting component is arranged on the tool base 2 to limit the workpiece 1 to be measured on the tool base 2 for easy measurement.

[0026] By setting a tooling base 2 and a limit assembly matching the piece to be measured 1, the piece to be measured 1 is fixed on the tooling base 2 by utilizing the limit function of the limit assembly, and by limiting the movement of the piece to be measured 1 in the length direction and the width direction, and the tooling base 2 fits tightly with the piece to be measured 1, measurement errors caused by improper placement during deformation measurement due to the movement of the piece to be measured 1 can be avoided, the deformation measurement accuracy can be improved, and unqualified products can be avoided from entering the market. At the same time, the measuring tool can save measurement time, reduce the workload of quality inspectors, and achieve the purpose of improving measurement efficiency.

[0027] In the measuring tool of this embodiment, the limiting assembly includes protrusions 3 for limiting the length direction of the workpiece 1 to be tested. The protrusions 3 are located at both ends of the workpiece 1 to be tested. The workpiece 1 to be tested is clamped between the protrusions 3 on both sides of the tool base 2.

[0028] Specifically, the protrusions 3 at both ends are provided to fix the length direction of the workpiece 1 to limit the longitudinal displacement of the workpiece 1 on the tooling base 2 to avoid relative movement between the workpiece 1 and the tooling base 2 to affect the measurement.

[0029] Preferably, a 2 mm gap is left between the protrusion 3 and the left and right edges of the workpiece 1 to achieve positioning and prevent the workpiece 1 from being stuck with the tooling base 2 , making it easier to remove the workpiece 1 from the tooling base 2 .

[0030] Further preferably, the protrusion 3 is tilted on one side close to the test piece 1 to form a guide surface with an inclination, which facilitates the placement of the test piece 1 and guides the test piece 1 to be clamped between the protrusions 3 at both ends to achieve positioning and facilitate measurement.

[0031] The tooling base 2 is made of aluminum, with R5 chamfers at both ends. The humanoid design serves as a guide, making it easier for fingers to reach in and hold the tooling for transportation.

[0032] In order to avoid the tooling base 2 being too long as an overall structure and prone to deformation, which would reduce the guide measurement accuracy, preferably, the tooling base 2 can be provided with an assembly structure, which is divided into two parts, a left part and a right part, a splicing groove is provided at the bottom of the left part, and a splicing block 9 matching the splicing groove is provided on the right part, and the splicing is achieved by engaging the splicing block 9 with the splicing groove and fixing it with bolts.

[0033] In the measuring tool of this embodiment, the limiting assembly further includes a support seat 4 located between the protrusions 3 on both sides of the tool base 2 , and the support seat 4 abuts against the workpiece 1 to provide support and limiting for the workpiece 1 .

[0034] Specifically, a support seat 4 is provided to support and limit the main body of the workpiece to be tested 1. The shape of the surface of the support seat 4 is consistent with the shape of the standard specification workpiece, so that the support seat 4 fits with the workpiece to be tested 1, so that the difference between the workpiece to be tested 1 and the standard specification, that is, the deformation amount, is reflected to facilitate measurement. The support seat 4 serves as a reference and cooperates with the measuring tool to realize the measurement of the deformation amount.

[0035] Preferably, the support seat 4 and the tool base 2 are also made of aluminum material, which is light and strong, corrosion-resistant, and easy to process, and together with the tool base 2 forms a height difference deformation measurement tool.

[0036] In the measuring tool of this embodiment, a step 5 is provided at one end of the support seat 4 , and the shape of the step 5 matches the edge shape of the workpiece 1 to limit the width direction of the workpiece 1 .

[0037] Specifically, the step 5 matches the edge shape of the test piece 1, and the test piece 1 is sleeved on the outside of the step 5 to limit the width direction of the test piece 1 on the tooling base 2, thereby limiting 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.

[0038] In the measuring tool of this embodiment, a first reference surface 6 is provided at one end of the tool base 2 , and a first measuring position is formed between the first reference surface 6 and the workpiece 1 to facilitate measuring the deformation of the workpiece 1 .

[0039] Specifically, the test piece 1 is a large door panel assembly, which includes a plastic part 16. The large door panel plastic part 16 refers to the appearance component product at the air outlet of the circular cabinet air conditioner. The assembly gap with other components is required to be small to avoid affecting the appearance quality. Therefore, the large door panel assembly has strict requirements on the deformation amount.

[0040] 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 seat 4. The bottom surface of the step 5 is the first reference plane 6. The gap between the first reference plane 6 and the edge of the plastic part 16 is the first measuring position. The size of the gap reflects the deformation of the plastic part 16. The deformation of the first end of the door panel assembly is obtained by measuring the gap with a feeler gauge.

[0041] Preferably, the plastic part 16 is made of ABS rubber material, which has high impact resistance and can produce products with high finish.

[0042] In the measuring tool of this embodiment, a side of the tool base 2 away from the step 5 is provided with an escape groove 7 , and the escape groove 7 is used to accommodate screws on the edge of the test piece 1 so that the test piece 1 and the support seat 4 fit tightly.

[0043] Specifically, the part to be tested also includes a sheet metal part 17 assembled on the inner side of the plastic part 16, the purpose of which 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 components. The edge of the plastic part 16 is bent, and its width is greater than the sheet metal part 17. Therefore, the deformation of the plastic part 16 and the sheet metal part 17 are measured at both ends of the door panel assembly respectively; the screws on the edge of the part to be tested 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 in 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, an avoidance groove 7 is opened on the tooling base 2 to accommodate the protruding screw so that the screw is in a suspended state.

[0044] In the measuring tool of this embodiment, a second reference surface 8 is provided on one side of the tool base 2 where the avoidance groove 7 is provided, and a second measuring position is formed between the second reference surface 8 and the workpiece 1 to facilitate measuring the deformation of the workpiece 1 .

[0045] Specifically, the surface on which the avoidance groove 7 is opened is the second reference plane 8, the edge of the sheet metal 17 of the door panel assembly that meets the standards is flush with the surface of the avoidance groove 7, and the gap between the edge of the sheet metal 17 and the surface of the avoidance groove 7 is the second measuring position. By measuring the gap with a plug gauge, the deformation of the other end of the door panel assembly can be obtained.

[0046] Preferably, the first reference plane 6 and the second reference plane 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 deformation measurement accuracy.

[0047] In the measuring tool of this embodiment, the protrusions 3 are slidably connected to the tool base 2 , and the protrusions 3 at both ends of the tool base 2 slide along the length direction of the workpiece 1 to adjust the spacing and thus adapt to the workpieces 1 of different lengths.

[0048] Through the above arrangement, the distance between the protrusions 3 on both sides is adjusted to limit the positions of the test pieces 1 of different lengths, thereby adapting to the deformation measurement of products of different lengths.

[0049] In the measuring tool of this embodiment, a waist-shaped hole 10 is opened on the protrusion 3, and the waist-shaped hole 10 is arranged along the length direction of the test piece 1. A fastening bolt 11 is inserted into the waist-shaped hole 10, and the fastening bolt 11 is threadedly connected to the tool base 2.

[0050] Specifically, the fastening bolts 11 cooperate with different positions of the waist-shaped holes 10 to fix the protrusions 3 , thereby adjusting the spacing and positioning the protrusions 3 on both sides, and ensuring the limiting effect on the workpiece 1 to be tested.

[0051] In the measuring tool of this embodiment, a slide groove 12 is provided on the tool base 2, and the slide groove 12 is arranged along the length direction of the test piece 1. A slider matching the slide groove 12 is provided at the bottom of the protrusion 3, and the slider slides in the slide groove 12 to guide and limit the protrusion 3.

[0052] Specifically, a slide groove 12 is provided on the tooling base 2 to cooperate with the slide block as a guide groove for guiding the protrusion 3 to move in a straight line to avoid the guide surface of the side of the protrusion 3 from being deflected.

[0053] Embodiment 2: In the measuring tool of this embodiment, other settings adopt the same structure as that of embodiment 1. In addition, 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 is provided with two. The measuring base for supporting the workpiece 1 to be tested is detachably connected between the two limiting bases 13 .

[0054] Specifically, two parallel sliding grooves are provided on the limit base 13, which are respectively slidably connected to the protrusions 3, so a total of four protrusions 3 are arranged at the four corners of the tooling base 2 to improve the limiting effect; a support base 4 is arranged on the measuring base, and the split structure of the tooling base 2 is realized by providing a detachably connected measuring base and a limit base 13, and the limit base 13 is assembled with measuring bases of different lengths and shapes to perform limiting and deformation measurement on door panel assemblies of different sizes.

[0055] In the measuring tool 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 respectively detachably connected to the limiting base 13.

[0056] Specifically, the measuring base is divided into a first measuring base 14 and a second measuring base 15, which respectively measure the deformation on both sides of the door panel assembly, and the two are detachably connected to the limit base 13, respectively. Different first measuring bases 14 and second measuring bases 15 can be matched to adapt to the measurement of door panel assemblies of different shapes and specifications, thereby improving the adaptability of the tooling.

[0057] Specifically, the upper surfaces of the first measuring base 14 and the second measuring base 15 respectively match the inner surface shape contour of the gate panel assembly to provide effective limiting and support for the gate panel assembly. The inner side of the gate panel assembly is arc-shaped, and the surfaces of the first measuring base 14 and the second measuring base 15 fit the curvature of both sides of the arc.

[0058] Preferably, plug connectors are respectively provided at both ends of the first measuring base 14 and the second measuring base 15, and a plug hole is opened on the limiting base 13. The plug connector is plugged into the plug hole and is fastened by bolts to realize the assembly of the measuring base and the limiting base.

[0059] In the measuring tool of this embodiment, the first measuring base 14 cooperates with the plastic part 16 to measure the deformation of the plastic part 16 , and the second measuring base 15 cooperates with the sheet metal part 17 to measure the deformation of the sheet metal part 17 .

[0060] Specifically, a step 5 is provided on the first measuring base 14 to form a first reference surface 6 for measuring the deformation of the edge of the plastic part 16, and 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 a plug gauge.
