Description

Technical Field

[0001] This application belongs to the field of tooling and fixture technology, specifically relating to a fixture for a turntable for a current collector ring test simulation experiment. Background Art

[0002] Current collector rings have the following characteristics: Rotary test specimens typically consist of a rotor and a stator, each with an electrical interface. These interfaces are connected via internal wiring. Electrical signals are transmitted both when the rotor is rotating relative to the stator and when stationary. It is necessary to test the quality of this signal transmission at different relative speeds to ensure it meets the requirements of product testing. Current collector rings are large in size and heavy, making them difficult to handle. The stator and rotor need to be fixed separately, requiring precise clamping and a safe, stable, and reliable clamping system to prevent safety hazards during rotational testing. Current collector rings are produced in large quantities and batches, and traditional clamping methods suffer from inaccurate positioning, difficulty in fixing, and long clamping times, hindering testing efficiency. Furthermore, they suffer from unstable signal transmission when the stator and rotor rotate relative to each other.

[0003] Currently, no relevant fixture has been found that can quickly achieve the clamping and testing of the slip ring test piece; therefore, in order to improve the clamping efficiency of the slip ring and effectively improve the testing efficiency of the slip ring, there is an urgent need for a convenient fixture suitable for the slip ring joint test simulation turntable to meet the rotation simulation test of the slip ring and to meet the actual urgent needs of the slip ring functional performance verification.

DETAILED DESCRIPTION

[0033] Please see Figure 1 and Figure 2 This invention provides a fixture for a rotating test turntable for a current collector ring simulation test, which mainly consists of a rotating current collector ring mounting bracket 1, a transition fixture 2, and fasteners 3.

[0034] The adapter clamp 2 is mechanically connected to the clamp mounting base 14 of the collector ring mounting bracket 1; the collector ring rotor 4 is mechanically connected to the adapter clamp 2 to achieve precise positioning and fixation of the collector ring rotor.

[0035] The current collector stator is fixedly connected to the vertical tube positioning cover 11 of the current collector mounting bracket 1 via a vertical tube assembly, which can fix the current collector stator and restrict its rotation. The motor 12 drives the clamp mounting base 14 to rotate, thereby driving the current collector rotor to rotate. The electrical interface on the current collector rotor is connected to the input signal socket mounting plate 110 below the current collector assembly 112 via a dedicated cable fixed on the support ring 18. The input signal mounting plate 110 can rotate synchronously with the current collector rotor under the action of the lower lever 114. The input signal socket mounting plate 110 can rotate around the current collector assembly. The signal socket is installed on the input signal socket mounting plate 110. Each pin in the socket corresponds one-to-one with the pin of the output signal electrical interface socket, so that the electrical signal of the rotational movement can be converted into a static electrical signal output through the output signal electrical interface of the current collector assembly, which is convenient for signal detection. The support ring 18 is fixed above the clamp mounting base 14 by a vertical rod 17 and can rotate synchronously with the clamp mounting base 14.

[0036] This application provides a turntable for simulating the joint testing of current collector rings, which facilitates positioning, clamping, and signal transfer during joint testing of current collector ring products. It features reliable, secure, and convenient clamping, and stable and reliable signal transfer.

[0037] The rotary collector ring mounting bracket 1 is mounted on the upper surface of the turntable via the support plate 13, providing support for the rotary collector ring mounting bracket. The right base column 115 is fixedly mounted in the base column support 15. The collector ring assembly 112 is fixedly connected to the rotating sleeve 118 via screws and nuts. The rotating sleeve contains two layers of tin bronze bushings arranged vertically. By engaging with the shoulder of the right base column 115, a rotational support is formed, allowing the collector ring assembly 112 to rotate around the right base column 115. The cable fixing shield box 117 is mounted on the side plate of the lower mounting box of the collector ring assembly 112. The limiting plate 116 is mounted below the cable fixing shield box 117. The limiting plate 116 has an arc-shaped cam groove in the middle. A fixing pin is provided on the right base column 115 and inserted into the arc-shaped cam groove in the middle of the limiting plate. When the collector ring assembly 112 rotates, it achieves a 110° rotational limit and fixed angle through the limiting plate 116 and the fixing pin on the right base. When the current collector ring assembly 112 rotates 0° relative to the right base column, it is in the testing state; at 110°, it is used to make way for the current collector ring of the product under test to be installed vertically. This 110° rotation method enables convenient disassembly and assembly of the current collector ring of the product under test. The left base column 16 is connected to the support plate 13 through the base column support 15. The adjusting nut 19 is installed above the left base column 16, and its height can be adjusted up and down, thereby providing support for the current collector ring assembly 112 when it rotates to 0° relative to the right base column 115. A locking mechanism is installed and fixed on the side of the mounting box of the current collector ring assembly, which can lock the current collector ring assembly 112 at 0°, that is, at this time the position of the current collector ring assembly 112 is fixed and cannot be rotated around the right base column 115.

[0038] The adapter fixture can be adapted to different types of slip rings, thereby meeting the testing requirements of different types of slip rings.

[0039] In other embodiments of this application, a fixture for a current collector ring test simulation turntable is provided (see...). Figure 1 and Figure 2The system mainly comprises a rotary collector ring mounting bracket 1, an adapter clamp 2, and fasteners 3. The collector ring 4 rotor is fixedly connected to the clamp mounting base 14 of the collector ring mounting bracket 1 via the adapter clamp 2, enabling precise positioning and fixation of the collector ring 4 rotor. The collector ring 4 stator is fixedly connected to the vertical tube positioning mounting cover 11 of the collector ring mounting bracket 1 via a vertical tube assembly, enabling rotational fixation of the collector ring 4 stator and restricting its rotation. The motor 12 drives the clamp mounting base 14 to rotate, thereby driving the collector ring 4 rotor to rotate, thus achieving rotational movement of the collector ring 4 rotor relative to the stator. The electrical interface on the collector ring 4 rotor is fixed to a support ring 18. A dedicated cable connects to the input signal socket mounting plate 110 below the slip ring assembly 112. The input signal mounting plate 110, driven by the lower lever 114, rotates synchronously with the rotor of the slip ring 4. The input signal socket mounting plate 110 can rotate around the slip ring assembly 112. Each pin in the socket of the input signal socket mounting plate 110 corresponds one-to-one with the pin of the socket of the output signal electrical interface 113, enabling the electrical signal from the rotational motion to be converted into a static electrical signal output through the output signal electrical interface 113 of the slip ring assembly 112, facilitating signal detection. The support ring 18 is fixed above the clamp mounting base 14 by the column 17 and can rotate synchronously with the clamp mounting base 14.

[0040] This application provides a turntable for simulating the joint testing of current collector rings, which facilitates positioning, clamping, and signal transfer during joint testing of current collector ring products. It features reliable, secure, and convenient clamping, and stable and reliable signal transfer.

[0041] The rotating collector ring mounting bracket 1 (see...) Figure 2The rotating collector ring mounting bracket 1 can be supported by mounting it on the upper surface of the turntable via the support plate 13. The right base column 115 is installed and fixed in the base column support 15. The current collector ring assembly 112 is fixedly connected to the rotating sleeve 118 by screws and nuts. The rotating sleeve 118 contains two layers of tin bronze bushings distributed in an upper and lower structure. By cooperating with the shoulder of the right base column 115, a rotational support is formed, which can realize the rotation of the current collector ring assembly 112 around the right base column 115. The cable fixing shield box 117 is installed and fixed on the side plate of the lower mounting box of the current collector ring assembly 112. The limiting plate 116 is installed and fixed below the cable fixing shield box 117. The limiting plate 116 has an arc-shaped cam groove in the middle. The right base column 115 has a fixing pin, which is inserted into the arc-shaped cam groove in the middle of the limiting plate 116. At this time, when the current collector ring assembly 112 rotates, it achieves a rotation limit and a fixed angle of 110° through the limiting plate 116 and the fixing pin on the right base 115. When the collector ring assembly 112 rotates 0° relative to the right base column 115, it is in the testing state; at 110°, it is used to make way for the vertical installation of the collector ring 4 of the product under test. This 110° rotation method enables convenient disassembly and assembly of the collector ring 4 of the product under test. The left base column 16 is connected to the support plate 13 through the base column support 15. The adjusting nut 19 is installed above the left base column 16, and its height can be adjusted up and down, thereby providing support for the collector ring assembly 112 when it rotates to 0° relative to the right base column 115. A locking mechanism 111 is installed and fixed on the side of the mounting box under the collector ring assembly 112, which can lock the collector ring assembly 112 at 0°, that is, at this time the position of the collector ring assembly 112 is fixed and cannot rotate around the right base column 115.
