Abstract
Description
Technical Field
[0001] The present application relates to the technical field of harvesters, and in particular to a tooling for testing parts of harvesters. Background Art
[0002] There are many types of electrical appliances used in harvesting machinery. Since the testing standards for electrical appliances in harvesting machinery are stricter than those for passenger cars, they require rigorous testing in multiple stages, angles and types to meet the use standards. This requires the use of some fixtures to fix the electrical appliances being tested during different testing processes to ensure the stability of the tested electrical components.
[0003] The test tooling in the prior art is generally suitable for ordinary road passenger cars, and the related test tooling for harvesters is less in type and has a single function. Both of these toolings have several problems: First, the test product type is single. At present, the tooling used for testing harvesting machinery and electrical appliances has a fixed structure and a single function. It can only test a certain type of product, and there is a weight limit on the tested sample. When changing different tested parts, the corresponding test tooling needs to be replaced for adaptation and fixation, which reduces the test speed and increases the labor cost of repeatedly disassembling and assembling the tooling; Second, it is impossible to test multiple products at the same time. The test of harvesting machinery and electrical products sometimes requires multiple products for horizontal comparison, but under the existing test method, each product requires a corresponding tooling for assembly, which requires a large number of toolings and is costly. In addition, for test benches with limited installation space, it is impossible to test multiple tested products at the same time, which undoubtedly hinders the test progress and wastes time and cost; Third, it is impossible to test multiple angles at the same time. The existing test tooling can only maintain a certain specific angle for testing. If you want to adjust the angle of the tested product, you can only make tooling for multiple angles. This method directly increases the test cost.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0032] According to the present invention, a tool for testing parts of a harvester is provided, such as Figures 1 to 8 As shown, the tooling for testing parts of the harvester is suitable for vibration testing of parts of the harvester. The tooling for testing parts of the harvester comprises an adjusting plate 1 and a supporting plate group.
[0033] In the following description, reference will be made to Figures 1 to 8The detailed structures of the adjustment plate 1 and the support plate group of the tooling for parts testing of the harvester are specifically described.

Specifically, the adjustment plate 1 and the support plate group can be used as mounting plates for vibration testing of harvester parts. Both mounting plates can be provided with hollow holes, which can include multiple groups of hollow holes of different shapes and sizes. Harvester parts of various specifications can be installed on the adjustment plate 1 and the support plate group by selecting appropriate hollow holes.

The adjustment plate 1 can be formed as a rectangular plate, and a plurality of first connection holes 101 are provided at the four edges of the rectangular plate. The adjustment plate 1 can be stably installed on the support plate group through the plurality of first connection holes 101 at the four edges to increase the stability in the vibration test. At the same time, due to the provision of the plurality of first connection holes 101 and the plurality of second connection holes 5, parts with a larger weight can also be subjected to vibration testing on the parts testing tooling of the harvester.
[0036] like Figure 3 , Figure 5 and Figure 6 As shown, in the embodiment, a tilting block 201 is further provided in the middle of the support plate group, an angle is formed between the mounting surface of the tilting block 201 and the top surface of the support plate group, a plurality of third connection holes 202 are provided on the mounting surface of the tilting block 201, and the adjustment plate 1 is tiltedly provided on the support plate group through the first connection hole 101 and the third connection hole 202. The tilting block 201 can be formed as a long strip-shaped structural member, and the long surface of the long strip-shaped structure close to the top surface is the mounting surface, and an angle is formed between the mounting surface and the top surface of the support plate group, so that when the adjustment plate 1 is connected to the mounting surface, the adjustment plate 1 is in a tilted state. When the parts of the harvester need to be subjected to a tilted vibration test, the adjustment plate 1 can be tiltedly provided on the support plate group to realize a tilted vibration test of the parts of the harvester.
[0037] To sum up, the parts testing tooling of the harvester can test parts of multiple specifications of the harvester by adjusting the coordination of the plate 1 and the support plate group, meet the testing requirements of multiple specifications and multiple categories, and reduce the testing cost; it can also meet the testing of multiple angles and multiple weights, with a wide testing range, high reliability and high testing efficiency, and is easy to install and use, which solves the problem of frequent replacement of test tooling in the original test.
[0038] Preferably, if Figures 1 to 3 , Figures 5 to 8 As shown, in an embodiment, the support plate group may include a first support plate 2, a second support plate 3 and a third support plate 4. Since the adjustment plate 1 needs to change the test position, the support plate group needs to include a plurality of plates of different specifications. Specifically, the first support plate 2, the second support plate 3 and the third support plate 4 are all formed into an L shape, and the L-shaped structure includes a horizontal plate and a vertical plate, the end of the horizontal plate and the end of the vertical plate are vertically connected to each other, the horizontal plate is horizontal to the ground, and the vertical plate is perpendicular to the ground, and the vertical plate can be connected to the adjustment plate 1 to meet the horizontal and inclined arrangement of the adjustment plate 1. The horizontal plate is provided with a fixing hole 8 for connecting with a vibration table (not shown, the vibration table can be a vibration table in the prior art, which includes a through hole for tooling connection, and these structural features are known to those skilled in the art, so they are not repeated). The horizontal plate is connected to the installation through hole of the vibration table through the fixing hole 8. The support plate group can play a structural support role, and can also fix and support the adjustment plate 1, and make it have enough height space between the adjustment plate 1 and the vibration table for easy installation and fixation. It can also allow components with certain height requirements to be tested vertically.
[0039] Preferably, if Figure 5 and Figure 6 As shown, in the embodiment, the tilting block 201 is arranged on the vertical plate of the first support plate 2. Specifically, the tilting block 201 is arranged on the inner side surface of the vertical plate of the first support plate 2. In the embodiment, in order to ensure that the adjustment plate 1 can be stably installed in a tilted state, the number of the first support plates 2 is two, and the two first support plates 2 are arranged facing each other, and the tilting block 201 is arranged on the inner side surfaces of the two first support plates 2 facing each other.
[0040] Preferably, if Figure 5 and Figure 6As shown, in the embodiment, the vertical plate of the first support plate 2 is provided with a plurality of disassembly holes 203 arranged in sequence, and the tilting block 201 is detachably arranged on the vertical plate of the first support plate 2 through the disassembly holes 203. The user can install the tilting block 201 on the disassembly holes 203 at different positions, thereby changing the angle between the installation surface of the tilting block 201 and the top surface of the adjustment plate 1, thereby adjusting the tilt position of the adjustment plate 1, so that the harvester parts arranged on the adjustment plate 1 can be tested at different tilt angles, so as to achieve the purpose of multi-angle adjustment. For example, in Figure 5 and Figure 6 In the embodiment, the angle between the mounting surface of the tilting block 201 and the top surface of the adjusting plate 1 is 45 degrees, and the harvester parts can be subjected to a tilt vibration test at a tilt angle of 45 degrees. However, it is not limited thereto, and the position of the tilting block 201 can be changed to allow the harvester parts to be subjected to a tilt vibration test at a tilt angle of 30 degrees or 60 degrees.
[0041] Preferably, if Figure 5 and Figure 6 As shown, in the embodiment, the disassembly hole 203 is also provided on the side of the tilting block 201, and the disassembly hole 203 provided on the side of the tilting block 201 has the same specifications and dimensions as the disassembly hole 203 provided on the mounting surface of the tilting block 201, and the tilting block 201 is installed on the vertical plate of the first support plate 2 through the disassembly hole 203 on the side.
[0042] Preferably, as shown in Figure 4, in an embodiment, the hollow hole portion of the adjustment plate 1 may include a through circular hole 102, a cross hole 103, an annular hole group 104 and a waist-shaped hole group. The through circular hole 102 is arranged in the middle of the adjustment plate 1. The through circular hole 102 can avoid interference between the measured component with the wires coming out from below and the adjustment plate 1, and at the same time, the power supply cable can pass through the through circular hole 102 and connect with the power supply. The outer peripheral side of the through circular hole 102 is provided with a cross hole 103 and an annular hole group 104. The center of the cross hole 103 overlaps with the center of the through circular hole 102. The annular hole group 104 includes a plurality of long holes, and the plurality of long holes surround the through circular hole 102. In the embodiment, eight long holes are arranged, and the axes of the eight long holes overlap with the extension line of the diameter of the through circular hole 102. The interval angle between adjacent long holes is 30 degrees. The cross hole 103 and the annular hole group 104 can be used to fix the measured parts. At the same time, since these through holes are formed in a long strip shape, these through holes can facilitate the position adjustment of the measured parts thereon, and can also adapt to the measured parts of different specifications. In addition, the harvester parts (measured parts) can be installed in the hollow hole portion of the adjustment plate 1 by fixing bolts.
[0043] Preferably, as shown in Figure 4, in an embodiment, the waist-shaped hole group is arranged on the circumferential side of the circular hole 102. Further, the waist-shaped hole group may include a plurality of first waist-shaped holes 105 and a plurality of second waist-shaped holes 106, the extension direction of the first waist-shaped hole 105 is perpendicular to the extension direction of the second waist-shaped hole 106, and the two waist-shaped holes with different extension directions can be used to adapt to more specifications of parts. A plurality of first waist-shaped holes 105 are arranged in the first area of the adjustment plate 1, and a plurality of second waist-shaped holes 106 are arranged in the second area of the adjustment plate 1. The first area and the second area can be understood as the upper half and the lower half of the adjustment plate 1. The waist-shaped hole group can have a plurality of waist-shaped holes of different lengths and spaced apart from each other, which can be used to adapt to more specifications of parts. The tested parts can be installed on the adjustment plate 1 for horizontal and tilted vibration tests. The arrangement of the first waist-shaped hole 105 and the second waist-shaped hole 106 can adapt to the installation of most mounting holes of electrical components of harvesters. Even if some special components cannot be fixed on the same side, the components can be offset to the other side or rotated to find a suitable mounting hole for installation and fixation.
[0044] Preferably, as 5 and Figure 6 As shown, in the embodiment, the vertical plate of the first support plate 2 is provided with a hollow hole portion, and the hollow hole portion of the first support plate 2 includes a cross-shaped hole 6 and a third waist-shaped hole 7, the cross-shaped hole 6 is arranged on one side of the tilting block 201, and the third waist-shaped hole 7 is arranged in the middle of the vertical plate. The cross-shaped hole 6 and the third waist-shaped hole 7 can both be used for the installation of the tested parts, and the tested parts can be installed on the outer side of the first support plate 2. The outer side here means that the first support plate 2 is formed into an L shape, and the tested parts are installed on the outer side surface of the L-shaped vertical plate. The side of the vertical plate on which the tilting block 201 is installed can be understood as the inner side surface, and the side opposite to the inner side surface is the outer side surface. The tested parts are installed on the outer side surface of the vertical plate through the cross-shaped hole 6 and the third waist-shaped hole 7 to perform vertical vibration test of the tested parts.
[0045] Preferably, as 7 and Figure 8 As shown, in the embodiment, a hollow hole portion is provided in the middle of the vertical plate of the second support plate 3, and a hollow hole portion is provided in the middle of the vertical plate of the third support plate 4, and the hollow hole portion of the second support plate 3 and the hollow hole portion of the third support plate 4 are both formed as a crisscross hole 6 or a third waist-shaped hole 7. In the embodiment, the hollow hole portion of the second support plate 3 is formed as a crisscross hole 6, and the hollow hole portion of the third support plate 4 is formed as a third waist-shaped hole 7. Since the length of the second support plate 3 and the length of the third support plate 4 are both less than the length of the first support plate 2, the second support plate 3 and the third support plate 4 are both selectively provided with a crisscross hole 6 or a third waist-shaped hole 7. The second support plate 3 and the third support plate 4 can be used to install the measured parts with smaller specifications and lighter weight.
[0046] Preferably, as 1 to Figure 3 As shown, in the embodiment, the adjustment plate 1, the first support plate 2, the second support plate 3 and the third support plate 4 are detachably connected to each other. The detachable connection can be achieved through the first connection hole 101 and the second connection hole 5. Furthermore, the part testing tool of the harvester can be switched between a normal test state, a tilted test state and a reinforced test state to meet the testing requirements of different parts.
[0047] Preferably, as shown in Figure 1, in an embodiment, when the parts testing tool of the harvester is in a normal testing state, the number of the first support plates 2 is two, the two first support plates 2 are arranged facing each other, the second support plate 3 and the third support plate 4 are arranged facing each other, and the adjustment plate 1 is horizontally arranged on the top of the two first support plates 2, one second support plate 3 and one third support plate 4. At this time, the tested parts can be installed on the adjustment plate 1 for horizontal vibration testing, or installed on any one of the two first support plates 2, one second support plate 3 and one third support plate 4 for vibration testing. In addition, multiple parts of different specifications can also be installed on the parts testing tool of the harvester for simultaneous testing as long as the structural strength is met.
[0048] The normal test state is suitable for the test fixation of most harvester electrical components. The installation method in this state is: install the four plates of the support plate group on the vibration table through the fixing holes 8, adjust the distance between the two first support plates 2, and adjust the distance between the second support plate 3 and the third support plate 4, so that the adjustment plate 1 can be installed on the four plates of the support plate group.
[0049] When the tested electrical component needs to be vibrated in the horizontal direction, the mounting hole of the tested component is aligned with the hollow structure of the adjustment plate 1 and fixed, and fixed with fixing bolts. If the number of fixing bolts of the tested component is three or six and they are evenly distributed around the circle, they can be fixed on the annular hole group 104; if the number of fixing bolts of the tested component is four and they are evenly distributed around the circle, they can be fixed on the cross hole 103; if the power supply cable of the tested component is a bottom outlet, the power supply cable can be passed through the central through hole 102 and connected to the test power supply to achieve power supply and avoid interference. If the tested component has four mounting holes and is arranged in a rectangular matrix, such as a harvester display, it can be fixed through the first waist-shaped hole 105 and the second waist-shaped hole 106. If all the mounting holes of the tested component are designed to be long strips, the tested component can be rotated and moved, and a suitable mounting hole can be found to fix it.
[0050] When the electrical component under test needs to be vibrated in the vertical direction, the mounting hole of the tested component is aligned with the hollow structure of the first support plate 2 or the hollow structure of the second support plate 3 or the hollow structure of the third support plate 4, and fixed with fixing bolts. If the tested component has four or eight fixing bolts evenly distributed around a circle, it can be fixed on the cross-shaped hole 6. If the tested component is, for example, a harvester display screen, etc., which has four mounting holes arranged in a rectangular matrix, it can be fixed on the third waist-shaped hole 7. At this time, it is necessary to adjust the third waist-shaped hole 7 up and down according to the height of the display or other tested components to prevent the tested component from colliding with the vibration table during the test.
[0051] Preferably, as shown in Figure 3, in an embodiment, when the tooling for testing parts of the harvester is in a tilted test state, the number of the first support plates 2 is two, the two first support plates 2 are arranged facing each other, and the adjustment plate 1 is arranged on the tilting block 201 of the two first support plates 2. In the tilted test state, it is necessary to first adjust the position of the tilting block 201 according to the test requirements of the tested parts to change the angle between the mounting surface of the tilting block 201 and the top surface of the first support plate 2. Taking the angle of 45 degrees in the figure as an example, this angle can be used for the vibration test of the actual vehicle angle of the harvester display screen. The installation method of this state is: first, the tilting block 201 is installed on the inner side of the first support plate 2, and then the two first support plates 2 are installed on the vibration table through the fixing hole 8. During installation, the distance between the two first support plates 2 is adjusted so that the two sides of the adjustment plate 1 can be connected to the two tilting blocks 201 accordingly. When testing a component that needs a tilt vibration test, such as a display screen, the component to be tested is aligned with the hollow structure of the adjustment plate 1 and fixed with fixing bolts.
[0052] Preferably, if Figure 2 As shown, in the embodiment, when the parts testing tooling of the harvester is in the enhanced testing state, the number of the first support plates 2 is two, the two first support plates 2 are arranged facing each other, a second support plate 3 and / or a third support plate 4 are arranged between the two first support plates 2, the adjusting plate 1 is arranged on the top of the two first support plates 2 through the first connecting hole 101 and the second connecting hole 5, and the adjusting plate 1 is connected to the second connecting hole 5 of a second support plate 3 and / or the second connecting hole 5 of a third support plate 4 through a hollow hole portion.
[0053] The enhanced test state is suitable for large-mass harvester electrical parts. When in use, a second support plate 3 and / or a third support plate 4 can be placed between the two first support plates 2. You can choose to place a second support plate 3 or a third support plate 4 or a second support plate 3 and a third support plate 4 as needed. The top surfaces of the two first support plates 2, a second support plate 3 and / or a third support plate 4 are all connected to the adjustment plate 1. The installation method of the tested parts is the same as that of the normal test state, which will not be repeated here. The second support plate 3 and / or the third support plate 4 located in the middle can strengthen the structural strength of the adjustment plate 1 to prevent the structural deformation of the adjustment plate 1 during the vibration test of the large-mass tested parts.
[0054] The overall structure of the tooling for testing parts of the harvester is simple and low-cost. By adjusting the coordination of the plate and the support plate group, vibration tests of various specifications of parts of the harvester can be realized. The tooling structure is a sheet metal structure, which is only stabilized by screws, and does not require other complex process forms.
