[0056] In order to make the purpose, scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention. Unless otherwise specified, the terms used herein have the usual meanings in the art. The same symbols in the accompanying drawings represent the same components.

[0057] Please refer to Figures 1 to 13 The present invention proposes a safety welding device, which comprises: a base 1; Figure 3 As shown, a central slot 106 is provided in the middle of the top of the base 1, and bracket slots 105 are provided on both sides of the central slot 106; a rotation slot 101 is provided on the top surface of the base on one side of the central slot 106, and the rotation slot 101 is perpendicular to the central slot 106; an rib groove 102 and an axis slot 103 are provided on the top surface of the base on the other side of the central slot 106, and the rib groove 102 and the axis slot 103 are parallel to the central slot 106; T-shaped slide grooves 104 are provided on the top surface of the base on both sides of the central slot 106, and the T-shaped slide grooves 104 are parallel to the central slot 106 and are closer to the central slot 106 than the axis slot 103. The central slot 106 is used to place the welding parts, the bracket slots 105 on both sides are used to install the welding part bracket 8, the rotating slot 101 is used to install the rotating rod 4, the rib groove 102 and the shaft slot 103 are used to install the connecting shaft assembly 6, and the T-shaped slide groove 104 is used to install the robot arm bracket 10.

[0058] A guide block 7 is welded on the end surface of one end of the central slot 106 , and a support member 3 is fixedly installed on the bottom of the base 1 near the end of the T-shaped slide slot 104 .

[0059] like Fig. 9 As shown, the top surface of the support member 3 is fixedly connected with a hydraulic cylinder 301, the front end of the push rod of the hydraulic cylinder 301 is connected with a connecting plate 302, and the upper and lower end surfaces of the connecting plate 302 are welded with a connecting frame 303; the end of the connecting frame 303 is welded with a connecting ring 304; the inside of the connecting ring 304 is clamped with an inner clamp rod 305, and the inner clamp rod 305 is radially distributed along the circumference of the connecting ring 304 from the center of the connecting ring. In addition, as Figure 8 and Fig. 9 As shown, the center of the connecting ring 304 is opposite to the center of the guide block 7, and a protruding slider 306 is welded to the inner end of the inner clamping rod 305. The slider 306 is slidably engaged in the guide groove 701 opened on the guide block 7; the guide block 7 is conical in shape, and guide grooves 701 corresponding to the number of sliders 306 are arranged on the outer surface of the cone along the busbar direction.

[0060] The controller of the hydraulic cylinder 301 is installed inside the control component 5. After the hydraulic cylinder 301 is started by the control component 5, the connecting plate 302 is driven to move forward by the push rod, and the connecting plate 302 drives the connecting frame 303 and the connecting ring 304 to move forward. The connecting ring 304 drives the inner clamping rod 305 to move synchronously, and the slider 306 is slidably engaged in the guide groove 701. Through the guide groove 701, the inner clamping rod 305 gradually expands and moves outward during the forward movement until the outer end surface of the inner clamping rod 305 fits the inner wall of the workpiece to be welded, thereby tightening and fixing the workpiece to be welded so as to cooperate with the robot arm to complete the welding; when the hydraulic cylinder 301 is retracted, the inner clamping rod 305 can be driven to withdraw to its original position through the connecting ring 304, so that the welded workpiece can be removed and prepared for the next group of welding.

[0061] like Figure 4 As shown, a movable clamping rod 1001 is welded at the bottom of the robot arm bracket 10, and the movable clamping rod 1001 is slidably clamped in the inside of the T-shaped slide groove 104. The robot arm bracket 10 slides along the T-shaped slide groove 104 to manipulate the welding robot arm to move.

[0062] The shaft slot 103 is internally rotatably connected to the connecting shaft assembly 6; Figure 5 As shown, the connecting shaft assembly 6 is composed of a threaded shaft 61 and a fixed shaft 62; the fixed shaft 62 is clamped in the shaft clamping groove 103, and the fixed shaft 62 has an internal thread; a threaded connecting rod 6102 is welded at the end of the threaded shaft 61, and the threaded connecting rod 6102 is screwed with the internal thread of the fixed shaft 62, so the threaded shaft 61 and the fixed shaft 62 constitute two detachable parts. A shaft sleeve 204 is welded at the bottom of the protective member 2, and the shaft sleeve 204 is sleeved on the outside of the connecting shaft assembly 6 and can rotate.

[0063] In addition, if Figure 3 As shown, a rib groove 102 is provided on the top surface of the base 1, and an arc groove is provided at one end of the rib groove 102 close to the shaft clamping groove 103. The diameter of the arc groove is larger than the maximum outer diameter of the connecting shaft assembly 6. The rib groove 102 allows the threaded shaft 61 to be moved, so that the protective part 2 can be assembled or disassembled for inspection and maintenance. The arc groove can meet the movement of the connecting shaft assembly 6, and the screwing tool can be inserted into the arc groove without affecting the rotation of the threaded shaft 61.

[0064] In addition, if Figure 5 As shown, a hexagonal prism 6101 is welded to the outer end of the threaded shaft 61, and the hexagonal prism 6101 is clamped in the arc groove at the front end of the prism groove 102. The hexagonal prism 6101 is rotated by a screwing tool to rotate the threaded shaft 61 until it is disengaged from the fixed shaft 62. The hexagonal prism 6101 is then withdrawn backward in the prism groove 102 to complete the disassembly. Conversely, the hexagonal prism 6101 is slid forward in the prism groove 102, and the threaded connecting rod 6102 at the end of the threaded shaft 61 is inserted into the fixed shaft 62. The hexagonal prism 6101 is then rotated in the arc groove to complete the connection of the connecting shaft assembly 6, thereby completing the fixed installation of the rotating shaft of the protective member 2.

[0065] like Figure 5 , Figure 6 As shown, the protective member 2 has a protective plane, a shaft sleeve 204 is welded to the bottom of the protective plane, a display screen 202 is mounted on the protective plane, and two through holes 203 are opened on the protective plane, a protective cover 201 is mounted on the back of the protective plane, two clamping holes 2011 are opened on the protective cover 201, and the two clamping holes 2011 are respectively opposite to the two through holes 203 on the protective plane, a sliding clamping groove 2012 is opened on the top surface of the protective cover 201, and the control member 5 is slidably clamped inside the protective cover 201. A camera is also mounted on the protective member 2.

[0066] like Figure 7 , Fig.11 and Fig.13 As shown, a telescopic sleeve rod 501 is fixedly installed on the control member 5. The overall installation of the telescopic sleeve rod 501 is to pass through the clamping hole 2011 on the protective cover 201, the inside of the control member 5 and the through hole 203 on the protective plane in sequence, wherein the fixed rod part of the telescopic sleeve rod 501 is fixed inside the control member 5, and the telescopic rod part passes through the protective member 2. A rotating rod 502 is movably screwed inside the front end of the telescopic rod, and an externally threaded rod 5021 is welded to the end of the rotating rod 502. The externally threaded rod 5021 can be threadedly connected to the inside of the internally threaded tube 401. The internally threaded tube 401 is a part of the rotating rod 4. The structure of the rotating rod 4 is described below.

[0067] The top surface of the control member 5 is integrally formed with two balancing blocks 504 , the top surfaces of the balancing blocks 504 are attached to the inner top surface of the protective cover 201 , and the top surface of the balancing blocks 504 is threadedly connected to a pull rod 503 , which passes through a sliding slot 2012 on the top surface of the protective cover 201 and is exposed outside the protective cover 201 .

[0068] By pulling the pull rod 503, the control member 5 can be driven to move forward and backward in the protective cover 201. The fixed rod of the telescopic sleeve rod 501 is clamped inside the control member 5. Since the clamping hole 2011 and the through hole 203 are coaxial, one end of the two ends of the telescopic sleeve rod 501 can pass through the clamping hole 2011, and the other end can pass through the through hole 203 and move freely forward and backward. The distance from the rotating rod 4 can be adjusted through the telescopic sleeve rod 501 and the rotating rod 502. When the pull rod 503 is pulled outward, the control member 5 is driven to move backward, and the fixed rod of the telescopic sleeve rod 501 is clamped inside the control member 5, so that the telescopic rod can be pulled out, and the end of the telescopic rod is connected to the rotating rod 502, and the end of the rotating rod 502 is connected to the rotating rod 4, so the distance from the rotating rod 4 can be pulled away; after pulling the pull rod 503 back, the control member 5 is driven to move to the inside of the protective cover 201, and the telescopic sleeve rod 501 is contracted, which can shorten the connection distance with the rotating rod 4. Moreover, after releasing the connection with the rotating rod 4, the protective member 2 can be rotated to a horizontal state, and the telescopic sleeve 501 is retracted at the same time, and the bottom of the telescopic sleeve 501 is flush with the bottom surface of the base 1, thereby supporting the protective member 2 and the control member 5. Fig.12 shown.

[0069] Therefore, the protective cover 201 can provide protection for the control member 5, and the clamping hole 2011 cooperates with the through hole 203, so that the telescopic sleeve 501 can move freely, meeting the movement and support requirements of the protective member 2 in the vertical or horizontal state. The shaft sleeve 204 can rotate the protective member 2 to achieve the switching between the two states of vertical support use or horizontal lying. The display screen 202 can cooperate with the control buttons on the control member 5 to control the welding robot arm. The top surface of the control member 5 is equipped with a control button and is electrically connected to the internal controller. The control button on the top surface of the control member 5 is exposed in the rectangular opening on the top surface of the protective cover 201, and the operator can perform welding control on the welding robot arm.

[0070] The structure of the rotating rod 4 is as follows Fig.11As shown, an internal threaded tube 401 is welded to the front end face of the rotating rod 4, and a clamping shaft 402 is welded to the bottom end of the rotating rod 4; the internal threaded tube 401 is connected to the rotating rod 502; the clamping shaft 402 is rotatably clamped in the rotating groove 101, and can slide in the rotating groove 101, and can also rotate in the rotating groove 101; the rotating rod 4 body can be rotatably stored in the rotating groove 101. After the rotating rod 4 is turned to a vertical state, the internal threaded tube 401 faces forward, and the internal threaded tube 401 and the external threaded rod 5021 can be connected together through threaded engagement, thereby fixing the control part 5 and strengthening the connection between the protective part 2 and the rotating rod 4, ensuring that it plays a protective role when the welding robot arm is working; when the rotating rod 4 is turned to a horizontal state, the rotating rod 4 is clamped into the rotating groove 101 for storage for cleaning, such as Fig.12 Furthermore, two sets of rotating rods 4 are arranged on the top of the base 1 to support the protective member 2 and enhance the stabilizing effect.

[0071] The interior of the bracket slot 105 is used to clamp the welding bracket 8. Depending on the shape of the welding part, the welding bracket can be a round bottom bracket or a flat bottom bracket, such as Fig.13 Shown is a round bottom bracket 81, Fig.14 The flat bottom bracket 82 is shown. Generally speaking, the welding bracket 8 only needs to be made into the shape of half of the welding part, which saves materials and also meets the requirements of accommodating and stabilizing the welding part. A guide block 7 is set at one end of the welding bracket, and the guide block 7 is used to support one end of one welding part; a buckle block 9 is set at the other end of the welding bracket, and the buckle block 9 is used to support one end of another welding part; the two sections of the welding parts are opposite to each other and welding is carried out.

[0072] A circular slot 901 is provided on one side of the buckle block 9 (such as Fig.10 ), and a square card slot 902 is provided on the other side (as shown in Fig.12 As shown in FIG. 1 , the circular slot 901 is used to snap-fit ​​the round bottom bracket 81, and the square slot 902 is used to snap-fit ​​the flat bottom bracket 82. Similarly, the buckle block 9 can also be made into a half shape of the welding piece, and it only needs to abut against the welding piece.

[0073] In addition, a clip strip 903 ( Fig.10 As shown in the figure, the clamping strip 903 is installed in cooperation with the clamping slot at the bottom of the base 1 to clamp the snap-fit ​​block 9 to the bottom of the base 1. When the welding bracket 8 is clamped into the bracket clamping slot 105 and the welding part is loaded into the bracket, the snap-fit ​​block 9 is clamped to one end of the welding bracket 8, and one end of the welding part is also fixed, and the clamping strip 903 is used to complete the clamping connection between the snap-fit ​​block 9 and the base 1 for welding. The snap-fit ​​block 9 is easy to disassemble by using the clamping strip 903. When welding round parts, the round clamping slot 901 side is used, and when welding square or I-shaped parts, the square clamping slot 902 side is used. It is only necessary to take out the snap-fit ​​block 9 from the base, turn it over half a circle, and then clamp it.

[0074] The specific usage and function of this safety welding device are:

[0075] 1. Choose to use the round bottom bracket 81 or the flat bottom bracket 82 according to the shape of the workpiece to be welded, and then connect the welding bracket to the inside of the bracket slot 105; the welding robot arm is installed on the top surface of the robot arm bracket 10;

[0076] 2. Place the welded parts in the welding bracket, with one end of the welded parts against the guide block 7. If it is a pipe-shaped part, start the hydraulic cylinder 301 to open the inner clamping rod 305 and support it on the inner wall of the pipe;
