Description

Technical Field

[0001] The invention belongs to the field of equipment manufacturing, and in particular relates to a multifunctional integrated electrical operating table suitable for wire clamping and welding. Background Art

[0002] Slip rings, also known as electric slip rings, are important functional parts of electronic equipment such as radars. Its working principle is that the conductive ring and brush group are each welded with a part of the transmission wire, and a pair of electrically conductive friction pairs are formed between the two through assembly, ultimately achieving electrical connectivity between the fixed part and the rotating part. Column slip rings are a common slip ring structure in radar products, which are used to achieve stable transmission of power supply and various signals between the rotating array and the fixed base, ensuring that the cable will not be damaged by twisting during the rotation of the array.

[0003] The collector ring is generally composed of a current and signal transmission part and a mechanical transmission part. The current and signal transmission part mainly includes a ring core, a brush set, etc., and the mechanical transmission part includes a bearing, a fork, a housing, etc. According to the number of current and signal paths, the ring core is mainly assembled by alternating conductive rings and insulating rings, and multiple sets of conductive brushes are installed on the outer side of the conductive ring circumference. Each set of conductive rings and brushes forms a friction pair. The conductive ring is the main component of the ring core. In order to improve the efficiency of current and signal transmission, it is generally made of low resistivity and high conductivity materials, such as brass. At the same time, multiple signal transmission lines are generally welded on the conductive ring. In order to take into account solderability, gold plating is often chosen on the brass surface.

[0004] As the main functional part of signal transmission, the conductive ring usually has dozens of channels. If it is a power ring conductive ring, each channel will be welded with several high-power power signal transmission wires (the cross-sectional area is generally dozens of square millimeters). The welding is generally done manually and has the following characteristics:

[0005] 1) Solid brass has the characteristics of large volume and weight, high heat capacity and high thermal conductivity. It is difficult to weld and prone to cold welding defects.

[0006] 2) Each power conductive ring needs to be welded with several power transmission lines. Due to the high power and thick wire diameter, the maximum diameter can reach tens of square millimeters and the length can reach several meters, which makes clamping more difficult.

[0007] 3) In the laminated structure of the ring core, each wire of the lower conductive ring must pass through all the conductive rings above it and be in close contact with the insulating rings, which places strict requirements on the verticality of the wires after welding and the flatness of the welding point positions.

[0008] 4) Due to the large heat capacity, it takes a long time from heating the conductive ring to reaching the welding temperature and completing the welding operation.

[0009] Based on the above assembly characteristics, the welding of the conductive ring generally uses a hot plate as a heat source to heat the conductive ring as a whole and evenly heat it. However, the control of welding temperature, the verticality of the wire, and the quality of the solder joints during the welding process basically rely on the experience of the operator. At the same time, due to the different diameters and lengths of the wires, the cable clamping process mainly relies on customized tooling, which has the problems of difficult assembly, poor versatility, and time-consuming changes. Summary of the invention

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Combination Figure 1 The operating table of the present invention comprises an electrical workbench 1, a temperature control and temperature monitoring system, an adjustable wire clamping device 3, and a wire fast fixing mechanism 4. The temperature control and temperature monitoring system comprises an embedded hot plate 21, a temperature control display box 22, a three-color indicator light 23, and an infrared temperature sensor 24. The embedded hot plate and the electrical workbench are integrated into one design, which eliminates the height difference between the hot plate and the operating table, and the workpiece can be more conveniently translated up and down the hot plate. During the welding operation, the welding temperature and the over-temperature alarm temperature are first set through the temperature control display box 22, and then the temperature of the conductive ring to be welded on the hot plate is monitored by the infrared temperature sensor 24 installed on the top of the operating table. When the conductive ring is in a heating state and has not reached the set welding temperature, the three-color indicator light 23 displays green, indicating that the state is normal; when the conductive ring reaches the set temperature, the three-color indicator light 23 displays yellow, indicating that welding can be performed; when an abnormality occurs during the welding process and the temperature exceeds the over-temperature alarm temperature, the three-color indicator light 23 displays red, which plays the role of over-temperature alarm.

[0029] Combination Figure 2The adjustable wire clamping device (3) comprises a hidden rail 31, a mounting frame 32, and a connecting rod 33. The adjustable wire clamping device 3 mainly provides support for the wire tightening mechanism, and can be adjusted according to the size of the conductive ring to be welded and the length of the wire, as follows: the hidden rail 31 is installed on the top of the electrical workbench, and the upper cover plate is a back-lifting type, which is convenient for repairing and maintaining the rail. The mounting frame 32 is fixed on the hidden rail 31 and is a two-stage structure. The extension length can be adjusted perpendicular to the direction of the rail according to the size of the conductive ring (the workpiece to be welded) to ensure the vertical state of the wire fixed by the tightening mechanism. The connecting rod 33 is used to connect the mounting frame 32 and the wire quick fixing mechanism 4. The position of the wire quick fixing mechanism 4 can be adjusted up and down on the connecting rod 33 according to the length of the wire to be welded. After adjusting to the position, the wire quick fixing mechanism 4 is fixed with the stop screw 46 at the back.

[0030] Combination Figure 3 The wire quick fixing mechanism 4 includes a mounting plate 41, a clamp 42, a pin 43, a spring pin 44, a tightening screw 45, and a stop screw 46. When the wire and the conductive ring are welded, the quick fixing mechanism 4 can be used to fix the wire to ensure the verticality and consistency of the wire in the welding state. The mounting plate 41 and the clamp 42 are connected by the pin 43, and the clamp 42 takes the pin 43 as the center of the circle and can be opened and closed and rotated in the same plane. The other end of the clamp 42 is a spring pin 44. Pull up the spring pin 44 and the clamp can be rotated. Each wire is fixed in the hole position of the contoured fixing hole opened on the mounting plate 41 (suitable for wires with an outer diameter of Ф8 to Ф18). If the wire diameter is thin, the tightening screw 45 can be used to adjust the extension length to ensure that the wire is fixed securely and will not shake.

[0031] During the working process, when the conductive ring and the wire are assembled and welded, the extension length of the adjustable wire clamping device 3 and the height of the wire quick fixing mechanism 4 are adjusted according to the size of the conductive ring to be welded and the length of the wire to be welded. Assemble the wire with the conductive ring, and fix the wire with the adjustable wire clamping device 3 and the wire quick fixing mechanism 4, and slide the assembled conductive ring and wire to the embedded hot plate 21 through the hidden guide rail 31. Turn on the temperature control system, and after completing the setting of the welding temperature and the alarm temperature, the hot plate starts to heat, the temperature monitoring system lights up green, and displays the temperature of the welded conductive ring. While heating, the operator can simultaneously carry out the clamping operation of the next conductive ring. After the conductive ring is heated to the set temperature, the three-color indicator light 23 changes from green to yellow, prompting the operator to perform welding. The operator completes the welding of the wire and the conductive ring on the embedded hot plate 21 by filling solder. After welding is completed, the embedded hot plate 21 is closed, and after the welding point is fully cooled, the welded conductive ring is transferred to the cooling station through the hidden guide rail 31 to continue cooling. At the same time, the next clamped conductive ring can be transferred to the embedded hot plate 21 to start welding. If the workpiece temperature exceeds the alarm temperature during the process, the three-color indicator light 23 turns red to issue an over-temperature alarm.

[0032] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
