Description

Technical Field

[0001] This utility model relates to testing fixtures, specifically a testing fixture for connecting multiple types of motors. Background Technology

[0002] Because of the complex structure of valve bodies, each valve body requires the design of a corresponding test fixture. Even for valve plates of the same type but different specifications, any change in the oil holes requires a redesign of the test fixture. Therefore, the initial cost is very high, the production cycle is very long, and the previous fixtures cannot be reused, resulting in waste.

[0003] During the early stages of development, product switching was frequent, and testing workers needed to constantly change tooling, which was very troublesome and prone to errors, resulting in losses.

[0004] Therefore, this application designs a universal testing fixture for testing valve plates of the same type but different specifications. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a multi-model motor connection and testing fixture. Once installed on the motor, this fixture does not require replacement. When switching models, only the inlet and outlet oil pipes need to be replaced. The fixture body can be reused, reducing the cost and time of fixture manufacturing. Changing the inlet and outlet oil ports is simple and saves time.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a multi-model motor connection test fixture, comprising a fixture body and multiple inlet and outlet oil pipes of different models and specifications, wherein the multiple inlet and outlet oil pipes of different models and specifications are used to connect valve plates of different models and specifications; the fixture body is provided with a connecting plate for connecting the motor, and the fixture body is also provided with multiple oil holes, wherein the multiple inlet and outlet oil pipes of different models and specifications are provided with connecting pipes of the same specification, and the oil holes are connected to the connecting pipes.

[0007] An inner support sleeve is provided on the inner wall of the oil hole, and a gap is formed between the inner support sleeve and the tooling body, which can accommodate the connecting pipe of the inlet and outlet oil pipes.

[0008] The inner support sleeve can extend into the connecting pipe, the inner support sleeve is lower than the oil hole, and a sealing ring is provided on the outer wall of the inner support sleeve.

[0009] It also includes a fastening ring, which can be fitted onto the connecting pipe and is threaded into the threaded groove of the tooling body.

[0010] The fastening ring includes a ring body and a threaded ring plate, the threaded ring plate being connected to the outside of the ring body; a through hole is opened in the center of the ring body, and the connecting pipe passes through the through hole; the threaded ring plate can be threadedly connected to the threaded groove.

[0011] The ring body is also provided with a support ring. The inner ring surface of the support ring is inclined, making the support ring a wedge-shaped ring block that is larger at the top and smaller at the bottom. The tooling body has an annular notch, so that a fastening ring is formed between the annular notch and the oil hole. The inner ring wall of the annular notch is inclined, making the annular notch a wedge-shaped groove that is larger at the top and smaller at the bottom. The height of the support ring is less than the height of the annular notch, and the support ring can be embedded in the annular notch, thereby squeezing the fastening ring and clamping the connecting pipe.

[0012] A pull ring is also provided on the outer side of the ring body.

[0013] In summary, this utility model achieves the following technical effects:

[0014] This invention features a fixture body with multiple oil holes and various inlet / outlet oil pipes, all equipped with identical connecting pipes. All connecting pipes can connect to the oil holes. Since valve plates of the same type but different specifications differ only in the oil holes, when testing valve plates of different specifications, simply remove the existing inlet / outlet oil pipes from the fixture body and replace them with those corresponding to the valve plate being tested. There is no need to replace or disassemble the fixture body, which can be reused. The connecting pipes are of the same specification, ensuring compatibility with all types of inlet / outlet oil pipes. Attached Figure Description

[0024] Example:

[0025] Figure 1This is a multi-model motor connection test fixture, including a fixture body 1 and various inlet and outlet oil pipes 3 of different models and specifications. The various inlet and outlet oil pipes 3 of different models and specifications are used to connect valve plates of different models and specifications. The fixture body 1 is provided with a connecting plate 2 for connecting the motor. The fixture body 1 is also provided with multiple oil holes 101. The various inlet and outlet oil pipes 3 of different models and specifications are provided with connecting pipes 301 of the same specification. The oil holes 101 are connected to the connecting pipes 301.

[0026] This invention features multiple oil holes 101 on a single tooling body, equipped with various inlet and outlet oil pipes 3. All inlet and outlet oil pipes 3 are fitted with identical connecting pipes 301, allowing all connecting pipes 301 to connect to the oil holes 101. Since valve plates of the same type but different specifications differ only in the oil holes, when testing valve plates of different specifications, only the existing inlet and outlet oil pipes on the tooling body need to be removed and replaced with those corresponding to the valve plate under test. There is no need to replace or disassemble the tooling body, which can be reused. The connecting pipes are of the same specification, ensuring compatibility with all types of inlet and outlet oil pipes with the oil holes. This invention solves the problem of needing a motor-driven rotor pump for oil supply performance testing during the development of hybrid hydraulic valve plates, while also ensuring compatibility with valve plates of different shapes. It reduces the number of tooling components required, lowers costs, and increases the speed of tooling changeover.

[0027] Figure 2 yes Figure 1 A partial cross-sectional view shows that an inner support sleeve 102 is provided on the inner wall of the oil hole 101. A gap 103 is formed between the inner support sleeve 102 and the tooling body 1. The gap 103 can accommodate the connecting pipe 301 of the oil inlet and outlet pipes 3.

[0028] The inner support sleeve 102 can extend into the connecting pipe 301. The inner support sleeve 102 is lower than the oil hole 101. A sealing ring 104 is provided on the outer wall of the inner support sleeve 102.

[0029] This utility model features an inner support sleeve 102, which provides support and connection within the connecting pipe 301, enhancing the tightness of the connection. Combined with the sealing ring 104, it achieves a sealing effect.

[0030] like Figure 2 As shown, it also includes a fastening ring 4, which can be fitted onto the connecting pipe 301 and is threadedly connected to the threaded groove 105 of the tooling body 1.

[0031] This application utilizes a fastening ring 4 to increase the tightness between the connecting pipe and the oil hole.

[0032] Figure 3 yes Figure 2A partially enlarged schematic diagram shows that the fastening ring 4 includes a ring body 401 and a threaded ring plate 402. The threaded ring plate 402 is connected to the outside of the ring body 401. A through hole is opened in the center of the ring body 401, and the connecting pipe 301 passes through the through hole. The threaded ring plate 402 can be threadedly connected to the threaded groove 105.

[0033] Specifically, the ring body 401 is also provided with a support ring 403. The inner ring surface of the support ring 403 is inclined, making the support ring 403 a wedge-shaped ring block that is larger at the top and smaller at the bottom. The tooling body 1 has an annular notch 106, so that a fastening ring 107 is formed between the annular notch 106 and the oil hole 101. The inner ring wall of the annular notch 106 is inclined, making the annular notch 106 a wedge-shaped annular groove that is larger at the top and smaller at the bottom. The height of the support ring 403 is less than the height of the annular notch 106. The support ring 403 can be embedded in the annular notch 106, thereby squeezing the fastening ring 107 and clamping the connecting pipe 301.

[0034] When the fastening ring of this application is tightened downwards, the support ring 403 enters the annular notch 106. Due to the contact action of the wedge-shaped surface, the support ring 403 gradually squeezes the fastening ring 107 inwards, thereby clamping the connecting pipe 301 with the fastening ring 107.

[0035] In order to effectively tighten and loosen the fastening ring 4, this application also provides a pull ring 404 on the outer side of the ring body 401. Figure 1 Only one fastening ring 4 shows the pull ring 401; the other fastening rings do not show the pull ring 401. The pull ring 404 is provided to facilitate control of the fastening ring 4 even if the inlet and outlet oil pipes 3 are irregularly shaped.

[0036] The tooling base for connecting the motor is universally compatible with various types of products, and once installed on the motor, it does not need to be removed and replaced. When switching to other valve bodies, only the inlet and outlet oil pipes need to be replaced, which solves the problem that the tooling cannot be reused when the oil inlet layout of the valve body is changed, and eliminates the need to invest in a new set of tooling for each version, thus reducing costs.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
