Description

Technical Field

[0001] This utility model relates to the field of positioning and detection tools, specifically to a general-purpose fixture for testing agricultural machinery products. Background Technology

[0002] As agricultural machinery products with CVT and power shift systems gradually increase in production, the assembly needs to undergo offline testing after completion. However, the test fixtures in the experimental center are not universal, and the assembly cannot be fixed. Therefore, it is necessary to design a fixture that is compatible with the testing needs of different products and is easy to operate. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a universal fixture for testing agricultural machinery products, so as to solve the problem that the existing testing fixtures have a single purpose and cannot be compatible with multiple products.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a universal fixture for testing agricultural machinery products, including a support base and a V-shaped clamp unit that can be detachably installed on the support base.

[0005] The V-shaped clamp unit includes a V-shaped base mounted on a support base and quick clamps mounted at both ends of the V-shaped base.

[0006] The V-shaped base includes a horizontal section and inclined sections installed at both ends of the horizontal section, with a receiving cavity formed between the inclined sections.

[0007] The quick clamp is installed at the end of the inclined section facing away from the horizontal section.

[0008] The top surface of the support base is provided with clamp connection holes and product connection holes.

[0009] This utility model also has the following technical features: The inclined section is also equipped with a clamp mounting platform on the side facing away from the horizontal section, and the quick clamp is mounted on the clamp mounting platform.

[0010] The angle between the inclined segment and the horizontal segment is 40°, and the angle between the two inclined segments is 80°.

[0011] The inclined section is equipped with a shockproof plate on the side facing the horizontal section.

[0012] The anti-smashing plate is in the shape of a cuboid plate, including an anti-smashing base plate and a protective protrusion installed on one side of the length direction of the anti-smashing base plate. The protective protrusion is arranged away from the inclined section.

[0013] The support base includes a mounting base plate and a first mounting platform, a second mounting platform, and a third mounting platform that are sequentially mounted on the mounting base plate.

[0014] The first and third mounting platforms are at the same height, while the second mounting platform is at a greater height than both the first and third mounting platforms.

[0015] The clamp connection hole is located on the top of the first mounting platform and the third mounting platform, and the product connection hole is located on the top of the second mounting platform.

[0016] The bottom surface of the horizontal section is mounted on the first mounting platform and the third mounting platform.

[0017] The mounting base plate is also provided with several first fixing holes and positioning pin holes.

[0018] Several second fixing holes are also provided on the bottom plate of the horizontal section.

[0019] Compared with the prior art, this utility model has the following technical effects: (I) The present invention provides a general-purpose fixture for testing agricultural machinery products. By installing a V-shaped clamp unit on the support base, when the agricultural machinery product to be tested is a power shift FSP28 series product, the two sides of the wheel housing of the power shift FSP28 series are V-shaped inclined surfaces. The V-shaped clamp unit 2 is used for support, and the quick clamp clamps are used to fix the product on the fixture, and the test bench can be tested normally.

[0020] When the agricultural machinery product under test is a CVT or FSP26 series power shift vehicle, the area below the wheel housing of the CVT or FSP26 series power shift vehicle is flat. Remove the V-shaped clamp unit and directly connect the agricultural machinery product under test to the support base through the product connection hole. The test bench can then perform normal testing.

[0021] When changing products, only the upper V-shaped clamp unit needs to be replaced, while the lower support base remains unchanged. This allows for testing of different products and offers strong compatibility.

[0022] (II) The present invention provides a general-purpose clamp for testing agricultural machinery products, which uses two quick clamps to press on the wheel side housing. Each clamp has a force of 1 ton, ensuring a firm clamping and eliminating the need for bolt connections, making it convenient to operate and improving assembly efficiency.

[0023] (III) The present invention provides a general-purpose fixture for testing agricultural machinery products, which is simple in structure, easy to operate, safe and reliable, and highly adaptable. Attached Figure Description

[0038] Example 1: This embodiment provides a universal fixture for testing agricultural machinery products, such as... Figures 1-5 As shown, it includes a support base 1 and a V-shaped clamp unit 2 that is detachably mounted on the support base 1.

[0039] The V-shaped clamp unit 2 includes a V-shaped base 2-1 mounted on a support base 1 and quick clamps 2-2 mounted on both ends of the V-shaped base 2-1.

[0040] The V-shaped base 2-1 includes a horizontal section 2-1-1 and inclined sections 2-1-2 installed at both ends of the horizontal section 2-1-1, with a receiving cavity formed between the inclined sections 2-1-2.

[0041] The quick clamp 2-2 is installed at the end of the inclined section 2-1-2 facing away from the horizontal section 2-1-1.

[0042] The top surface of the support base 1 is provided with clamp connection hole 3 and product connection hole 4.

[0043] The position of the support base 1 on the test bench is determined by the positioning pin, and then the support base 1 is fixed on the test bench by 8 M20 bolts. The V-shaped clamp unit 2 is connected to the support base 1 by bolts and clamp connection holes 3.

[0044] When the agricultural machinery product under test is a power shift FSP28 series product, the bottom of the wheel housing of the power shift FSP28 series is irregularly shaped and cannot be used for positioning. The two sides are V-shaped bevels, which can be used for positioning. Use V-shaped clamp unit 2 for support, quick clamp 2-2 to clamp, fix the product on the fixture, and the test bench can test normally.

[0045] When the agricultural machinery product under test is a CVT or power shift FSP26 series product, the bottom of the wheel housing of the CVT or power shift FSP26 series is flat and has 4 M22 threaded holes. Remove the V-type clamp unit 2 and directly connect the agricultural machinery product under test to the support base 1 through the product connection hole 4. The test bench can then perform normal testing.

[0047] The quick clamp 2-2 described above uses CH-71225.

[0048] As a preferred embodiment: like Figure 1 and Figure 2 As shown, the inclined segment 2-1-2 and the horizontal segment 2-1-1 form an angle of 40°, and the angle between the two inclined segments is 80°.

[0049] As a preferred embodiment: like Figure 1 and Figure 5 As shown, the inclined section 2-1-2 is equipped with a slam plate 3 on the side facing the horizontal section 2-1-1.

[0050] The anti-smashing plate 5 is generally rectangular in shape, including an anti-smashing base plate 5-1 and a protective protrusion 5-2 installed on one side of the anti-smashing base plate 5-1 along its length. The protective protrusion 5-2 is arranged away from the inclined section 2-1-2.

[0051] The anti-smashing plate 5 has holes for bolt connection with the inclined section 2-1-2.

[0052] As a preferred embodiment: like Figure 3 As shown, the support base 1 includes a mounting base plate 1-1 and a first mounting platform 1-1, a second mounting platform 1-2 and a third mounting platform 1-3 sequentially mounted on the mounting base plate 1-1. The first mounting platform 1-1 and the second mounting platform 1-2 are located on both sides of the third mounting platform 1-3.

[0053] The first mounting platform 1-1 and the third mounting platform 1-3 are at the same height, and the second mounting platform 1-2 is at a greater height than the first mounting platform 1-1 and the third mounting platform 1-3, to prevent interference between the agricultural machinery product under test and the first mounting platform 1-1 and the third mounting platform 1-3 when the second mounting platform 1-2 is used alone.

[0054] The clamp connection hole 3 is opened on the top of the first mounting platform 1-1 and the third mounting platform 1-3, and the product connection hole 4 is opened on the top of the second mounting platform 1-2.

[0055] The bottom surface of the horizontal segment 2-1-1 is mounted on the first mounting platform 1-1 and the third mounting platform 1-3.

[0056] The mounting base plate 1-0 is also provided with several first fixing holes 1-4 and positioning pin holes 1-5; the mounting base plate 1-0 is fixed to the test bench with bolts through the first fixing holes 1-4 and positioned by positioning pins through the positioning pin holes 1-5.

[0057] The bottom plate of the horizontal section 2-1-1 is also provided with several second fixing holes 2-1-4.

[0058] The first mounting platform 1-1 and the third mounting platform 1-3 are used to fix the V-shaped clamp unit 2. The clamp connection hole 3 on the first mounting platform 1-1 and the third mounting platform 1-3 corresponds to the second fixing hole 2-1-4 opened on the bottom plate of the horizontal section 2-1-1, and is connected by bolts.

[0059] The product connection hole 4 is used to connect the agricultural machinery product to be tested.

[0060] The specific working process of this utility model: The support base 1 has two φ16 locating pin holes 1-5, which serve a positioning function to determine the position of the entire fixture. The mounting plate 1-1 of the support base 1 has eight M20 bolt holes (first fixing holes 1-4), which are used to fix the support base 1 to the upper surface of the test bench with eight M20 bolts and nuts. Above are three square platforms, each with four M20 bolt holes (clamp connection hole 3 and product connection hole 4), connecting to the V-shaped base 2. If the product is changed, the bolts are removed, and only the parts above the support base 1 are replaced, facilitating product changeover and saving changeover time. The support base 1 has eight reinforcing ribs to ensure the strength of the tooling. Figure 3 .

[0061] The bottom surface of the horizontal section 2-1-1 of the V-shaped base 2-1 has eight φ22 through holes (second fixing holes 2-1-4). Eight M20 bolts pass through and are screwed into the threaded holes (first fixing holes 1-4) on the upper surface of the support base 1, fixing the V-shaped base 2-1 to the support base 1. The V-shaped base 2-1 has a V-shaped structure with an included angle of 80° and an inner distance of 382.6mm, ensuring that parts can be easily placed on the V-shaped base 2-1. The inclined section 2-1-2 has four M8 threaded holes on each side facing the horizontal section 2-1-1 for fixing the anti-smashing plate 5. The top of the inclined section 2-1-2 is a clamp mounting platform 2-1-3 with a length of 95mm and a width of 100mm, forming an angle of 90° with the side of the inclined section 2-1-2 facing the horizontal section 2-1-1. The flat surface has four M8 threaded holes for connecting the quick clamp 2-2, such as... Figure 4 .

[0062] The anti-smashing plate 5 is made of nylon. The anti-smashing base plate 5-1 is fixed to the inclined section 2-1-2 with four M8 screws. There is a 20mm high protective protrusion 5-2 on the right side, which serves as a limit. Each set is equipped with two anti-smashing plates 5. Figure 5 . The quick clamp 2-2 is a standard part, model CH-71225, with a clamping force of 1 ton, which meets the usage requirements. It is fixed to the clamp mounting table 2-1-3 by 4 M8 screws.

[0063] Install a set of clamps on each side of the test bench to support the wheel housing of the part under test. Hoist the assembly onto the test bench, place the wheel housing on the V-shaped support base, adjust the quick clamp to clamp the assembly, and start the test.

[0064] When the agricultural machinery product under test is a power shift FSP28 series product, the bottom of the wheel housing of the power shift FSP28 series is irregularly shaped and cannot be used for positioning. The two sides are V-shaped bevels, which can be used for positioning. Use V-shaped clamp unit 2 for support, quick clamp 2-2 to clamp, fix the product on the fixture, and the test bench can test normally.

[0065] When the agricultural machinery product under test is a CVT or power shift FSP26 series product, the bottom of the wheel housing of the CVT or power shift FSP26 series is flat and has 4 M22 threaded holes. Remove the V-type clamp unit 2 and directly connect the agricultural machinery product under test to the support base 1 through the product connection hole 4. The test bench can then perform normal testing.

[0066] The above technical solutions are only preferred embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be conceived by those skilled in the art without creative effort within the technical scope disclosed in this utility model are covered within the protection scope of this utility model.
