Description

Technical Field

[0001] The utility model relates to the field of conductive slip rings, and particularly relates to a cooling structure for a high-speed conductive slip ring. Background Technique

[0002] A conductive slip ring is a precision power transmission device that realizes power and signal transmission between two relatively rotating mechanisms. It is suitable for use in occasions where unrestricted continuous or intermittent rotation is required, and power or signals are transmitted from rotating parts to fixed parts. It is widely used in fields such as aerospace, aviation, and ground weaponry. It consists of an elastic material - brush, a sliding contact surface material - conductive ring, an insulating material, a bonding material, a combined bracket, precision bearings, a dust cover, and other slip ring auxiliary parts. The brush is made of a precious metal alloy material and is in a "II" shape in symmetric double contact with the conductive ring groove. It transmits signals and current by sliding contact with the conductive ring groove under the elastic pressure of the brush. The precision conductive slip ring belongs to a high-tech product and has been applied to the high-tech military field. It is a key device for various precision turntables, centrifuges, and inertial navigation equipment.

[0003] For the existing conductive slip rings, the heat dissipation efficiency is relatively low. The current through-hole conductive slip rings cannot meet the customer's requirements at higher speeds. The high speed causes excessive heat generation in the friction pair, which will lead to unstable signal transmission and greatly reduced service life. To solve the above problems, we propose a cooling structure for a high-speed conductive slip ring. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cooling structure for a high-speed conductive slip ring, and its advantage is high heat dissipation efficiency.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A cooling structure for a high-speed conductive slip ring, including a through-hole conductive slip ring, a fixing frame is installed on the surface of the through-hole conductive slip ring, a fixing shell is bolted between the inner walls of the fixing frame, an inlet pipe and an outlet pipe are fixedly sleeved on the inner walls of the fixing shell and the through-hole conductive slip ring, one ends of the inlet pipe and the outlet pipe are respectively communicated with an inlet plate and an outlet plate, and both the inlet plate and the outlet plate are bolted to the inner wall of the fixing frame. Through holes are opened on the surfaces of the inlet plate and the outlet plate. A cooling cavity is arranged between the fixing shell and the through-hole conductive slip ring. The other ends of the inlet pipe and the outlet pipe are both communicated with a fixing head, and the fixing head is bolted to the surface of the fixing frame. A connecting pipe is slidably sleeved on the inner wall of the fixing head. A sliding cylinder is slidably sleeved on the surface of the fixing head. A first spring is arranged between the sliding cylinder and the surface of the fixing frame. A triangular groove is opened on the inner wall of the sliding cylinder. A clamping rod is slidably connected to the inner wall of the triangular groove. A second spring is sleeved on the surface of the clamping rod. A clamping groove is opened on the surface of the connecting pipe, and the clamping rod is clamped with the clamping groove.

[0006] Adopting the above technical solution, the coolant enters the liquid inlet plate through the liquid inlet pipe, and then enters the cooling cavity through the through holes on the liquid inlet plate. The coolant passes through the cooling cavity to take away the heat generated by the conductive slip ring, enters the liquid outlet pipe through the through holes on the liquid outlet plate, and returns to the coolant tank through the connecting pipe for cooling. In this way, the purpose of good cooling effect can be achieved, the heat generated by the friction of the slip ring due to high-speed operation can be effectively reduced, and it can meet the customer's need for the through-hole conductive slip ring to operate at high speed for a long time to collect stable signal transmission. This not only improves the accuracy and stability of the signal collected by the customer, but also improves the service life of the slip ring. By moving the sliding cylinder, the movement of the sliding cylinder drives the movement of the triangular groove, so that the clamping rod disengages from the clamping groove under the action of the second spring, and the connecting pipe is removed. During installation, the connecting pipe is inserted into the fixed head, the sliding cylinder is released, and the sliding cylinder drives the triangular groove to reset under the action of the first spring, and the clamping rod is clamped with the clamping groove to fix the connecting pipe, completing the installation, thus achieving the purpose of facilitating the installation and disassembly of the connecting pipe, reducing the workload, and improving the efficiency of installation and disassembly.

[0007] The present utility model is further provided that: a first sealing gasket is provided between the fixed bracket and the through-hole conductive slip ring.

[0008] Adopting the above technical solution, by providing a second sealing gasket, the sealing performance is improved.

[0009] The present utility model is further provided that: anti-slip lines are provided on the surface of the sliding cylinder.

[0010] Adopting the above technical solution, by providing anti-slip lines, hand slipping is prevented and operation is facilitated.

[0011] The present utility model is further provided that: both ends of the clamping rod are arc-shaped.

[0012] Adopting the above technical solution, by providing that both ends of the clamping rod are arc-shaped, the clamping of the clamping rod is prevented and stability is ensured.

[0013] The present utility model is further provided that: a second sealing gasket is provided between the inner walls of the connecting pipe and the fixed head.

[0014] Adopting the above technical solution, by providing a second sealing gasket, liquid leakage between the connecting pipe and the fixed head is prevented, and the sealing performance is ensured.

[0015] The present utility model is further provided that: a heat conduction sheet is integrally formed on the surface of the through-hole conductive slip ring, and the heat conduction sheet is located inside the cooling cavity.

[0017] The present utility model is further provided that: an O-ring is provided between the fixed bracket and the liquid inlet plate and the liquid outlet plate.

[0018] With the above technical solution, by setting an O-ring, the sealing performance between the fixing frame and the liquid inlet plate and the liquid outlet plate is improved.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In the utility model, the coolant enters the liquid inlet plate through the liquid inlet pipe, and then enters the cooling cavity through the through holes on the liquid inlet plate. The coolant takes away the heat generated by the conductive slip ring after passing through the cooling cavity, enters the liquid outlet pipe through the through holes on the liquid outlet plate, and returns to the coolant tank through the connecting pipe for cooling.
