DETAILED DESCRIPTION

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] First embodiment:

[0021] See also Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of the vacuum chamber track welding fixture. Figure 2 This is a schematic diagram of the installation structure of the bidirectional screw. Figure 3 It is a schematic diagram of the installation structure of the worm.

[0022] The present invention provides a vacuum chamber track welding jig and system, including a support leg 101, a base plate 102, a fixed seat 103, a rotating seat 104, a support plate 105, a worm gear 106, a worm 107, a clamping assembly 108 and an inclination sensor 109. The clamping assembly 108 includes a bidirectional screw 111 and a clamping plate 112. The support leg 101 is adapted to the unevenness of the inner wall of the vacuum chamber by telescoping, and the worm 107 is driven to rotate by the first rotating motor 110, so that the worm 107 drives the worm wheel 106 to rotate, and the worm wheel 106 drives the rotating seat 104 and the support plate 105 to rotate, thereby adjusting the angle of the support plate 105 and the track. It can be understood that the above scheme can be used to facilitate the adjustment of the angle of the welding track, and can also be used to adjust the length of the support leg 101.

[0023] According to this specific embodiment, the base plate 102 is connected to the support leg 101 and is located on one side of the support leg 101. The fixed seat 103 is fixedly connected to the base plate 102 and is located on one side of the base plate 102. The rotating seat 104 is rotatably connected to the fixed seat 103 and is disposed on the fixed seat 103. The support plate 105 is fixedly connected to the rotating seat 104 and is disposed on the rotating seat 104. The worm gear 106 is fixedly connected to the rotating seat 104 and is disposed on the rotating seat 104. The rod 107 is rotatably connected to the base plate 102 and meshes with the worm gear 106. The clamping assembly 108 is arranged on the support plate 105. There are multiple support legs 101, which are evenly arranged at the bottom of the base plate 102. A first rotary motor 110 is also installed on the base plate 102. The output end of the first rotary motor 110 is connected to the worm 107. The clamping assembly 108 is used to clamp and fix the track on the support plate 105. The support legs 101 can be extended and retracted to adapt to the unevenness of the inner wall of the vacuum chamber.

[0024] During use, the device is placed inside a vacuum chamber, and by adjusting the length of the support legs 101, all the support legs 101 can contact the inner wall of the vacuum chamber, thereby stably supporting the bottom plate 102, thereby improving the stability of the support plate 105, and then the track to be welded is placed on the support plate 105. At this time, the track is clamped and fixed by the clamping assembly 108 to prevent the track from shaking during welding, thereby affecting the welding quality. After the track is clamped and fixed, the worm 107 is driven by the rotary motor to rotate, so that the worm 107 drives the worm wheel 106 to rotate, thereby driving the rotating seat 104 and the support plate 105 to rotate, thereby driving the track thereon to adjust the angle so that the track is in a horizontal state. At the same time, the self-locking property between the worm wheel 106 and the worm 107 improves the stability of the rotating seat 104 and the support plate 105, thereby preventing the track from shaking during welding, thereby facilitating the adjustment of the track angle and improving the welding quality and efficiency.

[0025] Among them, the inclination sensor 109 is fixedly connected to the support plate 105 and is arranged on the support plate 105; the inclination sensor 109 is electrically connected to the first rotating motor 110. When the support plate 105 drives the track to rotate and adjust the angle, the inclination sensor 109 monitors the inclination angle of the support plate 105 in real time, and converts the monitoring data into an electrical signal and transmits it to the first rotating motor 110. The control module built into the first rotating motor 110 analyzes and processes the received signal. If it is detected that the angle of the support plate 105 does not reach the preset horizontal state, the control module will automatically adjust the rotation direction and speed of the output end of the first rotating motor 110, and drive the worm 107 to rotate continuously until the data feedback from the inclination sensor 109 shows that the support plate 105 is in a horizontal position. At this time, the first rotating motor 110 will automatically stop running.

[0026] Secondly, the bidirectional screw 111 is rotatably connected to the support plate 105 and is arranged on the support plate 105; the clamping plate 112 is threadedly connected to the bidirectional screw 111, and is slidably connected to the support plate 105, and is sleeved on the bidirectional screw 111; the clamping assembly 108 is provided with multiple and evenly distributed on the support plate 105, and two clamping plates 112 are provided in one clamping assembly 108, and the clamping assembly 108 also includes a second rotating motor 114, which is installed on one side of the support plate 105, and the output end of the second rotating motor 114 is connected to the bidirectional screw 111, the thread directions on both sides of the bidirectional screw 111 are opposite, and the two clamping plates 112 are respectively located on both sides of the bidirectional screw 111, and the two A rubber pad 113 is provided on the opposite side of the clamping plate 112; the bidirectional screw 111 is driven to rotate by the second rotating motor 114, and then the two clamping plates 112 are driven to move toward or away from each other, thereby realizing rapid clamping and loosening of rails of different widths. The rubber pad 113 provided on the clamping plate 112 increases the friction between the clamping plate 112 and the rail, preventing the rail from being displaced due to vibration during welding, and also avoiding the clamping plate 112 from directly contacting the rail surface to cause scratches or damage; the second rotating motor 114 has a built-in torque sensor, which can monitor the clamping force in real time and transmit the data to the external control system. When it is detected that the clamping force is too large and may damage the rail, or the clamping force is too small to stably fix the rail, the control system will automatically adjust the rotation angle and torque of the second rotating motor 114 to achieve precise clamping.

[0027] When using the vacuum chamber rail welding jig of this embodiment, the device is placed inside the vacuum chamber. At this time, by adjusting the length of the support legs 101, all the support legs 101 can contact the inner wall of the vacuum chamber, thereby improving the stability of the support of the base plate 102; at this time, the rail to be welded is placed on the support plate 105, and the second rotary motor 114 drives the bidirectional screw 111 to rotate, so that the bidirectional screw 111 drives the corresponding two clamping plates 112 to approach, thereby clamping the left and right sides of the rail to prevent the rail from shaking during the welding process. At the same time, the angle of the support plate 105 is detected by the inclination sensor 109. When the support plate 105 is not in a horizontal state, the worm 107 is driven to rotate by the first rotary motor 110, so that the worm 107 drives the worm gear 106 to rotate, and the worm gear 106 drives the rotating seat 104 and the support plate 105 to rotate until the support plate 105 is in a horizontal state. At this time, the track on the support plate 105 is in a horizontal state, thereby facilitating the adjustment of the angle of the track and improving the quality and accuracy of track welding.

[0028] Second embodiment:

[0029] Based on the first embodiment, please refer to Figure 4 , Figure 4 It is a structural schematic diagram of the adsorption component of the second embodiment. The support leg 101 of this embodiment includes a shell 201, an electric push rod 202, an adjustment seat 203, an adsorption component 204, a laser displacement sensor 205 and a guide rod 206. The adsorption component 204 includes a vacuum pump 207 and a suction cup 208.

[0030] According to this specific embodiment, the shell 201 is fixedly connected to the base plate 102 and is located on one side of the base plate 102; the adjustment seat 203 is slidingly connected to the shell 201 and is located on the inner side of the shell 201; the electric push rod 202 is connected to the shell 201 and is located inside the shell 201, and the output end of the electric push rod 202 is connected to the adjustment seat 203; the adsorption member 204 is arranged on the adjustment seat 203; the adjustment seat 203 is driven to move by the electric push rod 202, and then the adjustment seat 203 is retracted into or extended into the shell 201, thereby achieving the purpose of adjusting the length of the support leg 101.

[0031] Among them, the laser displacement sensor 205 is connected to the adjustment seat 203 and is located inside the adjustment seat 203; the laser displacement sensor 205 is electrically connected to the electric push rod 202, and the laser displacement sensor 205 is used to monitor the relative position of the adjustment seat 203 and the inner wall of the shell 201 in real time, and feed back the data to the control system; during the adjustment process of the support leg 101, the control system accurately calculates the stroke of the electric push rod 202 based on the data of the laser displacement sensor 205, ensuring that the extended length of each support leg 101 accurately matches the contour of the inner wall of the vacuum chamber, thereby realizing rapid adaptive adjustment of the support leg 101.

[0032] Secondly, the guide rod 206 is fixedly connected to the shell 201 and slidably connected to the adjustment seat 203, and is arranged inside the shell 201; the movement of the adjustment seat 203 is guided by the guide rod 206, thereby improving the stability of the adjustment seat 203 during movement.

[0033] At the same time, the suction cup 208 is connected to the adjustment seat 203 and is located at the bottom of the adjustment seat 203; the vacuum pump 207 is connected to the adjustment seat 203 and is located on the inner side of the adjustment seat 203, and the vacuum pump 207 is connected to the suction cup 208 through a pipe; when the adjustment seat 203 is adjusted to contact the inner wall of the vacuum cavity, the suction cup 208 contacts the inner wall of the vacuum cavity, and the vacuum pump 207 is started at this time to extract the air inside the suction cup 208, so that the suction cup 208 is tightly adsorbed on the inner wall surface; the vacuum pump 207 is equipped with a pressure sensor for monitoring the vacuum degree in the suction cup 208 and transmitting the data to the control system. If the vacuum degree is detected to be lower than the preset threshold, it indicates that the adsorption force is insufficient, and the control system will automatically increase the suction power of the vacuum pump 207 to ensure that the support leg 101 is firmly adsorbed.

[0034] The present invention also includes a vacuum cavity orbital welding system, which is applied to the vacuum cavity orbital welding jig.
