[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Example 1

[0047] Reference Figure 1 , Figure 2 and Figure 4 The operating table is used in the field of automobile parts maintenance equipment, and mainly includes an operating table 1. The top of the operating table 1 is designed with a first support arm 6 and a second support arm 8, and both of them are provided with a fixed arm 11 inside for clamping and fixing the wheel hub. In addition, a placing plate 19 is also provided on the operating table, and the placing plate 19 cooperates with the two fixed arms 11 to clamp small accessories.

[0048] Reference Figure 1 and Figure 7A slidable U-shaped frame 35 is provided on the top of the operating table 1. An ultrasonic flaw detector 37 and a display screen 39 are installed at the bottom of the U-shaped frame 35. The ultrasonic flaw detector 37 is used to detect the accessories, and the display screen 39 is used to display the relevant information of the accessories, which is convenient for maintenance personnel to analyze and judge.

[0049] Reference Figure 1 and Figure 6 Two second storage slots 29 are provided on the top of the operating table 1, and a tool rack 33 is installed in each second storage slot 29. A plurality of tool bags 34 are provided on the side close to each other of the tool racks 33 for placing various maintenance tools. In order to facilitate maintenance personnel to easily take tools, the present invention also designs an adjustment structure, which is located in the second storage slot 29, and the position or angle of the tool bag 34 can be adjusted by mechanical or pneumatic means, thereby simplifying the access process.

[0050] Reference Figure 1-Figure 3 The first clamping structure includes a transmission groove 2 arranged on the top of the operating table 1, and a bidirectional screw rod 3 is rotatably connected in the groove. Two nut blocks 4 are respectively threadedly connected to the positive and negative thread sections of the bidirectional screw rod 3, and a movable disk 5 is fixed on the top of the two nut blocks 4, and the movable disk 5 slides on the top of the operating table 1. The first support arm 6 is fixed on one of the movable disks 5, and the second support arm 8 is fixed on the other movable disk 5. By driving the bidirectional screw rod 3 to rotate by a motor, the two movable disks 5 and the first support arm 6 and the second support arm 8 can be controlled to move toward or away from each other. The first support arm 6 and the second support arm 8 are both provided with a first receiving groove 7 inside, and a rotating shaft 9 is rotatably connected in the receiving groove, and a gear 10 is fixedly sleeved on the rotating shaft 9, and a fixed arm 11 is sleeved on the rotating shaft 9. A slide rod 15 is also slidably penetrated through the top of each support arm, and an arc-shaped clamping tooth 14 is provided at the bottom end of the slide rod 15, which is engaged with the gear 10. A tension spring 16 is sleeved on the outer wall of the slide bar 15 , and two ends of the tension spring 16 are fixedly connected to the top of the first support arm 6 and the second support arm 8 and the corresponding slide bar 15 , respectively.

[0051] Specifically, when in use, first pull the arc-shaped latching teeth 14 upward to release the engagement, rotate the fixed arm 11 out of the storage slot and place it horizontally, and then, under the action of the tension spring 16, the arc-shaped latching teeth 14 engage with the gear 10 again to position the fixed arm 11. After that, place the wheel hub on the arc-shaped support plate 49 on the operating table, and adjust the height of the wheel hub by the electric push rod 43 so that it is coaxial with the fixed arm 11. Next, drive the bidirectional screw rod 3 to move the first support arm 6 and the second support arm 8 toward the middle, insert the fixed arm 11 into the wheel hub, and the rotating ring 12 abuts against both sides of the wheel hub for clamping.

[0052] Reference Figure 2-Figure 5The second clamping structure includes two movable grooves 20 arranged at the top of the placement plate 19, each movable groove 20 is fixed with a fixed rod 21, and a clamping plate 22 is slidably sleeved on the fixed rod 21. The clamping plate 22 contacts one end of the fixed arm 11 and is used to transmit the clamping force. A spring 23 is sleeved on the outer wall of the fixed rod 21, one end of which is fixed to the fixed rod 21, and the other end is fixed to the inner wall of the movable groove 20, so as to provide elastic force for the clamping plate 22 to move outward. The two clamping plates 22 are rotatably connected to a rotating sleeve 25 on one side close to each other, and a screw 26 is connected to the inner thread of the rotating sleeve 25. A clamping plate 27 is fixed to the end of the screw 26, and the clamping plate 27 slides on the top of the placement plate 19.

[0053] Specifically, the placement plate 19 is inserted into the slots 13 of the two fixed arms 11, and the clamping plate 22 is engaged with the clamping slot 24 under the action of the spring 23 to position the placement plate 19. Then, the accessory is placed on the placement plate 19, and the first support arm 6 and the second support arm 8 are brought closer to each other by adjusting the bidirectional screw rod 3, and the spring 23 pushes the clamping plate 22 and the clamping plate 27 to initially clamp the accessory. In addition, by rotating the rotating sleeve 25, the distance between the clamping plate 27 and the clamping plate 22 can be adjusted, thereby controlling the clamping force and adapting to accessories of different sizes.

[0054] Reference Figure 1 and Figure 6 In order to achieve flexible adjustment of the tool rack 33 so that maintenance personnel can easily access tools without moving, an adjustment structure is provided in the application.

[0055] Reference Figure 1 and Figure 6 The adjustment structure specifically includes two parallel track grooves 30 respectively arranged on the inner walls of the second receiving groove 29 on both sides away from each other. The two track grooves 30 are used to guide and limit the sliding path of a fixed shaft 31. The fixed shaft 31 is designed to be able to slide freely in the track groove 30, and a damping bearing 32 is fixedly sleeved on its outer wall. The introduction of the damping bearing 32 is intended to provide a certain damping effect, so that when the tool holder 33 is rotated to a vertical state, it can be stably maintained in this position and will not easily change its position due to slight touch or vibration. The tool holder 33 is sleeved on the outer wall of the damping bearing 32. Through the indirect connection between the damping bearing 32 and the fixed shaft 31, the tool holder 33 can not only rotate around the fixed shaft 31 to realize the function of rotating out of the second receiving groove 29 and assuming a vertical state, but also can perform horizontal sliding adjustment in the second receiving groove 29.

[0056] This design allows maintenance personnel to easily adjust the distance between the tool rack 33 and themselves according to their work needs, so that they can conveniently take out the required tools from the tool bag 34 without moving their positions, greatly improving work efficiency and convenience of operation.

[0057] Reference Figure 3 and Figure 5 In order to further improve the stability and safety of electric vehicle accessories during maintenance, this embodiment introduces a matching mechanism of a card slot 24 and a card plate 22 between the fixed arm 11 and the placement plate 19, and adds a design of a rubber pad 28.

[0058] Specifically, the ends of the two fixed arms 11 close to each other are each provided with a slot 24, and the shape and size of these slots 24 match the card plate 22. When the placement plate 19 is matched with the slot 24 through the card plate 22, the placement plate 19 can be accurately limited to prevent it from unnecessary movement or shaking during the maintenance process.

[0059] Reference Figure 1 and Figure 6 In addition, in order to increase the friction between the clamping plate 27 and the accessory and prevent the clamping plate 27 from damaging the accessory surface, the present embodiment also fixes a rubber pad 28 on the side of the clamping plate 27 away from the clamping plate 22. The introduction of the rubber pad 28 not only improves the stability of the clamping, but also ensures the safety of the accessory during the maintenance process.

[0060] Reference Figure 1 and Figure 2 In order to realize convenient lifting and fixing of the wheel hub of the electric vehicle, the electric push rod 43 is fixed on the top of the operating table 1 in this embodiment, and its position is set between the first support arm 6 and the second support arm 8. An arc-shaped support plate 49 is fixedly connected to the output shaft of the electric push rod 43. The shape and size of the arc-shaped support plate 49 match the wheel hub and can stably support the wheel hub.

[0061] Specifically, during the maintenance process, the lifting and lowering movement of the arc-shaped support plate 49 and the wheel hub thereon can be conveniently realized by controlling the extension and retraction of the electric push rod 43. When the wheel hub needs to be raised to a position that matches the fixed arm 11, the lifting function of the electric push rod 43 only needs to be activated; conversely, when the wheel hub needs to be lowered after the maintenance is completed, the lowering function of the electric push rod 43 is activated. This design not only improves the efficiency and convenience of wheel hub maintenance, but also reduces the labor intensity of maintenance personnel.

[0062] Reference Figure 7 First, a slide rail is designed on the outer wall of the U-shaped frame 35 so that the U-shaped slider 36 can slide smoothly on it. Then, the ultrasonic flaw detector 37 is fixed to the bottom of the U-shaped slider 36 by bolts or other fastening methods to ensure that the ultrasonic flaw detector 37 can move freely on the U-shaped frame 35 with the U-shaped slider 36 to meet the detection needs of accessories of different sizes.

[0063] Reference Figure 7A slide groove matching the slide seat 38 is designed on the top inner wall of the U-shaped frame 35, so that the slide seat 38 can slide smoothly along the slide groove. Next, the display screen 39 is installed at the bottom of the slide seat 38 through a rotating shaft, so that the display screen 39 can not only move with the slide seat 38, but also adjust the angle, so that the maintenance personnel can view the detection information more clearly.

[0064] Reference Figure 7 , fix the mounting plate 40 on the side of the U-shaped frame 35 close to the first support arm 6, and then fix the lighting lamp 41 to the bottom of the mounting plate 40 by bolts or other means. The lighting lamp 41 should be a high-brightness, angle-adjustable LED lamp to ensure that sufficient lighting is provided for maintenance personnel to facilitate delicate maintenance operations.

[0065] Reference Figure 7 , the ultrasonic flaw detector 37 and the cameras 50 on both sides are electrically connected to the display screen 39 through data cables. In this way, the image detected by the ultrasonic flaw detector 37 and the images on both sides of the accessory taken by the camera 50 can be displayed on the display screen 39 in real time, which is convenient for maintenance personnel to understand the condition of the accessory in detail.

[0066] Reference Figure 3 , the holder 17 is fixed on one side of the first support arm 6 and the second support arm 8, respectively, to ensure that the holder 17 is stable and reliable. Then, the welding gun 18 is placed in the holder 17. Through the design of the holder 17, the welding gun 18 can be easily taken and is not easy to fall.

[0067] Example 2

[0068] refer to Figure 8 and Fig. 9 , improved on the basis of Example 1: on the side of the first support arm 6 away from the second support arm 8, the three-jaw chuck 42 is rotatably connected by a bearing or a similar mechanism to ensure that the three-jaw chuck 42 can rotate freely. On the side of the second support arm 8 away from the first support arm 6, a fixed plate 44 is provided, and two positioning rods 46 are fixed on the fixed plate 44. One end of the positioning rod 46 is designed with a sliding structure, which can smoothly pass through the second support arm 8 and the first support arm 6. A plurality of magnet blocks 45 are installed on the fixed plate 44, and an iron layer is covered on the side of the second support arm 8 away from the first support arm 6. The magnetic attraction between the magnet block 45 and the iron layer is utilized to enable the fixed plate 44 to be stably placed on one side of the second support arm 8.

[0069] A plurality of positioning grooves 47 are designed on the top of the two positioning rods 46 for positioning with the insert plate 48. The insert plate 48 is slidably connected on the side of the first support arm 6 away from the second support arm 8 so that the insert plate 48 can be engaged with the positioning grooves 47, thereby fixing the position of the positioning rod 46.

[0070] Specifically, when it is necessary to clamp shaft accessories, first pull the positioning rod 46 outward through the fixing plate 44 to disengage the positioning rod 46 from the first support arm 6. Next, store the fixed arm 11 on one side of the first support arm 6 into the first storage groove 7, and rotate the first support arm 6 180° so that the three-jaw chuck 42 is in a coaxial position with the fixed arm 11 on the second support arm 8. Then, re-insert the positioning rod 46 into the first support arm 6, and define the first support arm 6 and the second support arm 8 by the cooperation of the insert plate 48 and the positioning groove 47 to ensure that the three-jaw chuck 42 is coaxial with the fixed arm 11. Use the three-jaw chuck 42 to clamp one end of the shaft accessory, and at the same time start the bidirectional screw 3 to drive the first support arm 6 and the second support arm 8 closer, so that the fixed arm 11 on the second support arm 8 side contacts the other end of the accessory, thereby achieving a stable clamping of the accessory.

[0071] Finally, the three-jaw chuck 42 is driven by a motor to rotate, and the accessories are inspected and repaired. In this process, the position of the ultrasonic flaw detector 37 and the illuminator 41 can be adjusted as required to obtain the best detection and repair effect.

[0072] A method for using an electric vehicle parts maintenance operating table comprises the following steps:

[0073] S1.

Then, under the action of the tension spring 16, the gear 10 and the arc-shaped latching tooth 14 are engaged again to position the fixed arm 11. Then, the wheel hub is placed on the arc support plate 49, and the height of the wheel hub is controlled by the electric push rod 43 until the wheel hub is coaxial with the fixed arm 11. The bidirectional screw rod 3 is driven by the motor to rotate, and the bidirectional screw rod 3 drives the first support arm 6 and the second support arm 8 to move upward. During the intermediate movement, the two fixed arms 11 are inserted into the wheel hub, and the two rotating rings 12 respectively contact the two sides of the wheel hub and clamp the wheel hub. Then the maintenance personnel can turn the wheel hub to rotate and shoot the two sides of the wheel hub through the camera 50. At the same time, the U-shaped frame 35 can be pushed to slide and the ultrasonic flaw detector 37 can be moved to the top of the wheel hub. The ultrasonic flaw detector 37 can detect the situation inside the wheel hub, and the ultrasonic flaw detector 37 and the camera 50 display the data through the display screen 39, which is convenient for the staff to understand the situation of the wheel hub in detail, and the welding gun 18 can perform welding work according to the situation;

[0074] S2. When it is necessary to inspect and repair small accessories, the two fixed arms 11 are placed horizontally, the placement plate 19 is inserted into the two slots 13, and the clamping plate 22 is engaged with the clamping slot 24 under the elastic force of the spring 23 to position the placement plate 19. Then, the accessory is placed on the placement plate 19, and the first support arm 6 and the second support arm 8 are controlled to approach each other by the bidirectional screw rod 3. The clamping plate 27 can clamp the accessory under the action of the spring 23. In addition, rotating the rotating sleeve 25 can control the distance between the clamping plate 27 and the clamping plate 22, so as to further control the clamping force of the clamping plate 27 on the accessory and can clamp smaller accessories;

[0075] S3. When the maintenance personnel are performing maintenance, the tool rack 33 is rotated out of the second storage groove 29, and the tool rack 33 is in a vertical state. In addition, the tool rack 33 can be stably maintained in a vertical state under the action of the damping bearing 32, and the tool rack 33 can slide in the second storage groove 29 through the cooperation between the fixed shaft 31 and the track groove 30, so that the maintenance personnel can easily control the distance of the tool rack 33, so that the maintenance personnel can take out the tools from the tool bag 34 without moving, which greatly facilitates the work of the maintenance personnel;

[0076] S4. When shaft accessories need to be repaired, the positioning rod 46 is pulled outward through the fixing plate 44, and the positioning rod 46 is disengaged from the first support arm 6. Then, the fixing arm 11 on one side of the first support arm 6 is stored in the first storage groove 7. The first support arm 6 is rotated 180°, and the positioning rod 46 is re-through the first support arm 6. The first support arm 6 and the second support arm 8 are limited by the cooperation of the insert plate 48 and the positioning groove 47, so that the three-jaw chuck 42 and the fixing arm 11 are coaxial. One end of the shaft accessory is clamped by the three-jaw chuck 42, and the bidirectional screw 3 drives the first support arm 6 and the second support arm 8 to approach, while the fixing arm 11 on one side of the second support arm 8 contacts the other end of the accessory, so that the accessory can be clamped and fixed. Then, the three-jaw chuck 42 is driven to rotate by the motor, and the accessory can be inspected and repaired.
