Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a testing fixture for an integrated blade housing. Background Technology

[0002] The integrated blade casing in the battery has a hollow interior with openings at both ends. After the integrated blade casing is manufactured, it needs to undergo several tests. Specifically: First, a set amount of gas is filled into the integrated blade casing to conduct a pressure resistance test; second, gas is filled both inside the integrated blade casing and at the explosion-proof valve on the integrated blade casing to conduct an explosion-proof valve breathing test; third, gas is filled separately at the explosion-proof valve to conduct an explosion-proof valve burst test.

[0003] Therefore, given the diversity of test items, existing fixtures are only suitable for single tests, and different test items need to be carried out at corresponding tooling fixtures, which ultimately leads to poor applicability.

[0004] Clearly, the existing tooling only supports testing a single project. When testing different projects, different tooling needs to be changed multiple times, resulting in low testing efficiency and high workload. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a highly applicable and compact testing fixture for integrated blade housings.

[0006] To achieve the above objectives, this utility model can be implemented through the following technical solutions: A testing fixture for an integrated blade housing includes a base, characterized in that it further includes a fixing mechanism, a first clamping component, and a second clamping component; The aforementioned fixing mechanism is fixedly connected to the middle of the base and can position and connect the one-piece blade shell thereon. The number of the above-mentioned clamping components is two. The two clamping components are symmetrically connected to the base on both sides of the fixing mechanism. The two clamping components can press against the two ends of the one-piece blade shell of the fixing mechanism respectively. The aforementioned clamping component two is fixedly connected to the base between the two clamping components one, and the clamping component two can press against the side of the integral blade shell at the fixing mechanism.

[0007] In the aforementioned test fixture for an integrated blade housing, the fixing mechanism includes a fixing plate, a pressure plate, and a support plate. The fixing plate is vertically fixed to the base, and the support plate is fixed to the base. The inner end of the pressure plate is hinged to the upper part of the fixing plate. When the pressure plate swings around its hinge point toward the support plate, the integrated blade housing can be pressed tightly between the pressure plate and the support plate.

[0008] In the aforementioned test fixture for an integral blade housing, the pressure plate has a handle on the opposite side of its hinge.

[0009] In the aforementioned test fixture for the integrated blade housing, a positioning plate is also fixedly connected to the base, and a locking plate is detachably connected to the upper end of the positioning plate. When the integrated blade housing is positioned between the pressure plate and the support plate, the locking plate can press tightly against the upper end of the pressure plate.

[0010] In the aforementioned test fixture for an integrated blade housing, a limiting post is fixedly connected to the base. The limiting post is adjacent to the fixing plate. When the pressure plate swings away from the support plate, the limiting post can abut against the pressure plate.

[0011] In the aforementioned test fixture for an integrated blade housing, the clamping assembly includes a handle, a push rod, a guide unit, and a pressure plate unit. The handle is hinged to the base, the pressure plate unit is connected to the guide unit, one end of the push rod is hinged to the handle, and the other end of the push rod is connected to the pressure plate unit.

[0012] In the aforementioned test fixture for an integrated blade housing, the pressure plate unit 1 includes a base plate 1, an inner liner, an outer liner, and a sealing ring 1. The outer liner is frame-shaped, the inner liner is embedded in the outer liner, and there is a connection gap between the inner liner and the outer liner for the end of the integrated blade housing to be embedded. The sealing ring 1 is pressed tightly between the inner liner and the base plate 1, and the sealing ring 1 is directly opposite the connection gap.

[0013] In the aforementioned test fixture for an integrated blade housing, the base plate has a recessed connecting seat that matches the sealing ring, and the sealing ring is embedded in the connecting seat.

[0014] In the aforementioned test fixture for an integrated blade housing, both the inner liner and the outer liner are fixed to the base plate by corresponding fasteners.

[0015] In the aforementioned test fixture for an integrated blade housing, the base plate has a through-hole 1, and the inner liner has a through-hole 2, with the first and second vents facing each other to form an air intake channel 1 that can input gas to the fixing mechanism.

[0016] In the aforementioned test fixture for an integrated blade housing, the clamping assembly two includes a handle two, a push rod two, a slider, a guide rail, and a sealing ring two. The handle two is hinged to the base. The push rod two is arranged laterally and its inner end is hinged to the handle two. The outer end of the push rod two is connected to the slider. The guide rail is fixed to the base and connected to the lower part of the slider. The slider has an air intake channel two. The inlet end of the air intake channel two is located at the upper part of the slider, and the outlet end of the air intake channel two is located at the outer end of the slider. The sealing ring two is fixed to the outer end of the slider, and the outlet end of the air intake channel two is located inside the sealing ring two.

[0017] In the aforementioned test fixture for an integrated blade housing, the base is elongated, and a handle is fixedly connected to the edge of the base. There are four handles, which are located at the four corners of the base.

[0018] Compared with the prior art, the test fixture for the integrated cutter housing not only seals the integrated cutter housing in contact with it using clamping components one and two, but also allows gas to be continuously injected into the integrated cutter housing using clamping component one, and gas to be continuously injected into the explosion-proof valve of the integrated cutter housing using clamping component two.

[0019] By controlling whether air enters the first and second clamping components, multiple different test items can be completed separately. Clearly, this test fixture can adapt to multiple test items, demonstrating high applicability.

[0020] Meanwhile, the clamping component one, clamping component two, and fixing mechanism are independent unit components, and the three do not affect each other. Moreover, because they are distributed in different positions on the base, the entire test fixture appears to be compact and has high practical value. Attached Figure Description

[0032] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0033] like Figure 1-10 As shown, the integrated blade housing 2 has a hollow interior with openings at both ends, and an explosion-proof valve is located on the side of the integrated blade housing 2.

[0034] This test fixture for integrated blade housing includes a base 1, as well as a fixing mechanism, a clamping component one, and a clamping component two; The aforementioned fixing mechanism is fixedly connected to the middle of the base 1 and can position and connect the one-piece blade shell 2 thereon. The number of the above-mentioned clamping components is two. The two clamping components are symmetrically connected to the base 1 on both sides of the fixing mechanism. The two clamping components can press against the two ends of the one-piece blade shell 2 at the fixing mechanism respectively. The aforementioned clamping component two is fixedly connected to the base 1 between the two clamping components one, and the clamping component two can press against the side of the integral blade shell 2 at the fixing mechanism.

[0035] In this embodiment, the base 1 has a through-hole for weight reduction.

[0036] The fixing mechanism is used to stably position and connect the one-piece cutter housing 2 throughout the test fixture.

[0037] The one-piece tooling fixture has the following three test items: Test item 1: Fill the one-piece blade housing 2 with a preset amount of gas to conduct a pressure resistance test.

[0038] Test item two: Inflate the integrated blade housing 2 and the explosion-proof valve of the integrated blade housing 2 separately to conduct an explosion-proof valve breathing test on the explosion-proof valve on the integrated blade housing 2.

[0039] Test item 3: Inflate the explosion-proof valve separately to complete the explosion-proof valve burst test.

[0040] Regardless of the type of test being conducted, the integrated blade housing 2 must first be positioned on the base 1 using a fixing mechanism.

[0041] Two clamping components abut against both ends of the one-piece blade housing 2. One clamping component is provided with an air intake channel. After the air pressure inside the one-piece blade housing 2 is increased to a preset value through the air intake channel, the relevant work of test item one can be carried out.

[0042] Two clamping components are respectively positioned against both ends of the integrated blade housing 2. One clamping component is equipped with an air intake channel, through which the internal air pressure of the integrated blade housing 2 is increased to a preset value. At the same time, the second clamping component is positioned against the side of the integrated blade housing 2, and the preset air pressure is input to the explosion-proof valve of the integrated blade housing 2 through the air intake channel on the second clamping component, so that the relevant operations of test item two can be carried out.

[0043] The clamping component 2 rests against the side of the integrated blade housing 2. The clamping component 2 is equipped with a corresponding air intake channel. By inputting a preset air pressure into the explosion-proof valve of the integrated blade housing 2 through the air intake channel, the relevant operations of test item 3 can be carried out.

[0044] The fixing mechanism includes a fixing plate 3, a pressure plate 4, and a support plate 5. The fixing plate 3 is vertically fixed to the base 1, and the support plate 5 is fixed to the base 1. The inner end of the pressure plate 4 is hinged to the upper part of the fixing plate 3. When the pressure plate 4 swings around its hinge point toward the support plate 5, the integrated blade shell 2 can be pressed tightly between the pressure plate 4 and the support plate 5.

[0045] The support plate 5 is a flexible plate, which ensures that the one-piece blade shell can be stably positioned at the fixing mechanism, avoiding damage to the one-piece blade shell 2 due to rigid contact.

[0046] In this embodiment, the support plate 5 is made of rubber.

[0047] The pressure plate 4 has a handle 41 on the opposite side of its hinge.

[0048] The pressure plate 4 can be easily moved around its hinge by the handle 41.

[0049] A positioning plate 6 is also fixedly connected to the base 1. A locking plate 7 is detachably connected to the upper end of the positioning plate 6. When the integrated blade shell 2 is positioned between the pressure plate 4 and the support plate 5, the locking plate 7 can press tightly against the upper part of the pressure plate 4.

[0050] The locking plate 7 is connected to the positioning plate 6 by fasteners. When the locking plate 7 is pressed tightly onto the pressure plate 4, it can lock the pressure plate 4, so that the pressure plate 4 is in the locked state when it is in the positioning integrated blade shell 2 state.

[0051] A limiting post 8 is fixedly connected to the base 1. The limiting post 8 is adjacent to the fixing plate 3. When the pressure plate 4 swings away from the support plate 5, the limiting post 8 can abut against the pressure plate 4.

[0052] The limiting post 8 is made of flexible material to prevent rigid contact from occurring after the pressure plate 4 swings. Of course, the limiting post 8 allows the pressure plate 4 to swing within a set stroke range.

[0053] The clamping assembly includes a handle 9, a push rod 10, a guide unit 1, and a pressure plate unit 1. The handle 9 is hinged to the base 1. The pressure plate unit 1 is connected to the guide unit 1. One end of the push rod 10 is hinged to the handle 9, and the other end of the push rod 10 is connected to the pressure plate unit 1.

[0054] After applying external force to swing the handle 9, the push rod 10 transmits the aforementioned power to the pressure plate unit 1, which then moves stably under the action of the guide unit 1.

[0055] The pressure plate unit includes a base plate 11, an inner liner 12, an outer liner 13, and a sealing ring 14. The outer liner 13 is frame-shaped. The inner liner 12 is embedded in the outer liner 13 and there is a connecting gap 15 between the inner liner 12 and the outer liner 13 for the end of the integrated blade shell 2 to be inserted. The sealing ring 14 is pressed tightly between the inner liner 12 and the base plate 11 and the sealing ring 14 is directly opposite the connecting gap 15.

[0056] In this embodiment, the first guide unit is a guide rod 24 that is horizontally fixed on the base 1, and the guide rod 24 passes through the base plate 11.

[0057] The base plate 11 has a recessed connecting seat 111 that matches the sealing ring 14, and the sealing ring 14 is embedded in the connecting seat 111.

[0058] Both the inner liner 12 and the outer liner 13 are fixed to the base plate 11 by corresponding fasteners.

[0059] A connection gap matching the integral blade housing 2 is formed between the inner liner 12 and the outer liner 13. When the end of the integral blade housing 2 is connected to the connection gap 15, the sealing ring 14 abuts against the end of the integral blade housing 2 to achieve a stable seal at the end of the integral blade housing 2.

[0060] The base plate 11 has a through vent 112, and the inner liner 12 has a through vent 121. The vent 112 and the vent 121 are directly opposite each other and form an air intake channel that can input gas to the fixing mechanism.

[0061] Since the inner liner 12 abuts against the base plate 11 and the air hole 112 and the air hole 212 face each other, the air intake channel formed by the air hole 112 and the air hole 2121 allows external air pressure to smoothly enter the integrated blade shell 2.

[0062] The second clamping assembly includes a second handle 16, a second push rod 17, a slider 18, a guide rail 19, and a second sealing ring 20. The second handle 16 is hinged to the base 1. The second push rod 17 is arranged horizontally and its inner end is hinged to the second handle 16. The outer end of the second push rod 17 is connected to the slider 18. The guide rail 19 is fixed to the base 1 and is connected to the lower part of the slider 18. The slider 18 has a second air intake channel 23. The inlet end 231 of the second air intake channel 23 is located on the upper part of the slider 18, and the outlet end 232 of the second air intake channel 23 is located at the outer end of the slider 18. The second sealing ring 20 is fixed to the outer end of the slider 21, and the outlet end 232 of the second air intake channel 23 is located inside the second sealing ring 20.

[0063] After applying external force to push the handle 16, the power is transmitted to the slider 18 through the push rod 17. Under the action of the guide rail 19, the slider 18 is finally guaranteed to move smoothly and stably.

[0064] Since the outlet end 232 of the second air intake channel 23 has a sealing ring 20, when the slider 21 abuts against the integrated blade housing 2, the sealing of the explosion-proof valve on the integrated blade housing 2 can be guaranteed by the sealing ring 20.

[0065] The base 1 is elongated, and a handle 22 is fixedly connected to the edge of the base 1. There are four handles 22, which are located at the four corners of the base 1.

[0066] The entire tooling can be easily moved using handle 22.

[0067] In this test fixture for integrated cutter housings, clamping components one and two not only seal the integrated cutter housing in contact with it, but clamping component one also allows gas to be continuously injected into the integrated cutter housing, while clamping component two allows gas to be continuously injected into the explosion-proof valve of the integrated cutter housing.

[0068] By controlling whether air enters the first and second clamping components, multiple different test items can be completed separately. Clearly, this test fixture can adapt to multiple test items, demonstrating high applicability.

[0069] Meanwhile, the clamping component one, clamping component two, and fixing mechanism are independent unit components, and the three do not affect each other. Moreover, because they are distributed in different positions on the base, the entire test fixture appears to be compact and has high practical value.

[0070] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0071] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, 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.
