[0010] One end of the cantilever close to the control frame is extended to form a load-bearing arm, and one end of the cantilever away from the control frame is connected with a suction cup for fixing the distribution box panel.

[0011] Positioning components are arranged on the chassis, the round seat, the push rod and the control frame.

[0012] Preferably, the positioning assembly includes a sleeve fixedly inserted on the chassis, and the sleeve is located on the non-welded surface side of the distribution box frame, the bottom end of the sleeve is slidably connected to a detection pin, and a top spring is arranged in the sleeve, and the top spring pushes the detection pin to move downward.

[0013] The chassis is rotatably connected along the bottom of the round seat.

[0014] A through hole is provided in the middle of the control frame, and an engaging block is arranged on the inner side wall of the through hole. The push rod is movably inserted into the through hole, and a spiral groove matching with the engaging block is provided on the surface of the push rod.

[0015] The cantilever, the suction cup and the distribution box plate are provided with a two-way centering component.

[0016] Preferably, the bidirectional centering component comprises a slide rail vertically slidably connected to the cantilever, and a slide seat is transversely slidably connected to the slide rail, and the suction cup is arranged on the slide seat.

[0017] The slide rail and the slide seat are both provided with electromagnetic locks for locking themselves.

[0018] A magnetic seat is arranged on the inner side of the distribution box plate, and a shaft sleeve is fixedly arranged on the magnetic seat. A ring seat is rotatably connected to the shaft sleeve, and four V-shaped inclined frames are fixedly arranged on the outer ring of the ring seat.

[0019] A counterweight is fixedly arranged on the lower side of the ring seat.

[0020] A time-delay locking piece is arranged between the shaft sleeve and the ring seat.

[0021] Preferably, the time-delay locking member comprises a knob rotatably disposed in a shaft sleeve, a coil spring is disposed between the knob and the shaft sleeve, and a damping strip cooperating with the knob is disposed on the inner side of the shaft sleeve.

[0022] A locking pin matched with the ring seat is movably inserted into the surface of the shaft sleeve, and a protrusion matched with the locking pin is fixedly arranged on the surface of the knob.

[0023] Preferably, three auxiliary discs are distributed in an annular shape on the outer side of the suction cup.

[0024] Preferably, the groove body of the spiral groove is composed of two symmetrical sections connected to each other.

[0025] Preferably, a ball is rollingly embedded in the bottom end of the detection pin.

[0026] A method for using a welding processing table for preparing a distribution box comprises the following steps:

[0027] S1. Place the distribution box frame on the placement table with the box opening facing the front, fix it with an electromagnet, and then fix the distribution box panel along the suction cup;

[0028] S2, start the lifting frame to drive the slide and the round seat to move downward. During this process, the push rod contacts the top of the distribution box frame and moves upward along the round seat under pressure. At this time, the control frame moves upward synchronously with the push rod, and the oil smoke force arm pushes the cantilever to flip downward until the distribution box panel is attached to the distribution box frame. On the contrary, when the round seat moves upward, the cantilever flips upward and resets;

[0029] S3. When the distribution box frame is not placed correctly and misaligned with the cantilever and the distribution box panel, the detection pin is pressed down on the top of the distribution box frame. When the round seat moves down and pushes the push rod to move up in the opposite direction, the spiral groove on the surface of the rod body drives the control frame and the chassis to reciprocate for a certain amount along the insert block, so that the inspection pin performs synchronous circular motion. When the detection pin reaches the front side of the frame, the chassis rotates to align the cantilever, the box panel and the frame, and the detection pin bounces down along the frame to lock the rotating chassis. At this time, the push rod can drive the control frame to move up to operate the cantilever;

[0030] S4. After installing the box plate on the suction cup, center the magnetic base on the side of the box plate opposite to the frame. When the box plate fits the frame, the oblique frame is inserted into the frame and pushes the box plate in the opposite direction along the inner side to move horizontally and vertically along the slide rail and cantilever, so that the box plate and the frame are aligned.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] In the present invention, during the downward movement of the round seat, the push rod contacts the top of the distribution box frame and moves upward along the round seat under pressure. At this time, the control frame moves upward synchronously with the push rod, and the oil fume force-bearing arm pushes the cantilever to flip downward until the distribution box plate is attached to the distribution box frame. On the contrary, when the round seat moves upward, the cantilever flips upward and resets. Compared with the existing translational side plate for attachment, the above-mentioned push rod cooperates with the cantilever. On the one hand, the upward flipping of the distribution box plate can be used to reduce the obstruction of equipment and plates around the distribution box frame during the preliminary preparation process. On the other hand, after welding is completed, the distribution box can be flipped up as a whole to detect the welding strength by its own weight.

[0033] In the present invention, the spiral groove on the surface of the rod body is used to drive the control frame and the chassis to perform a certain amount of reciprocating rotation along the insert block, so that the inspection pin performs a synchronous circular motion. When the inspection pin reaches the front side of the frame, the chassis rotates to align the cantilever, the box plate and the frame, and the inspection pin bounces down to lock the rotating chassis along the frame. At this time, the push rod can drive the control frame to move up to operate the cantilever. Compared with the existing alignment of the frame and the equipment, the above-mentioned distribution box frame can be roughly placed while ensuring its overall direction. When the frame is not straight, the rotation of the chassis is used to rotate the cantilever and the box plate for alignment, and the box plate is automatically locked after alignment to fit the box plate. No complicated manual operation is required, which can effectively reduce the difficulty of manual precise placement of the frame and improve welding efficiency.

[0034] In the present invention, the magnetic base is centrally adsorbed on the side of the box plate opposite to the frame. During the process of the box plate fitting the frame, the oblique frame is inserted into the frame and reversely pushes the box plate along the inner side to perform lateral and vertical displacements along the slide rails and cantilevers, so that the box plate and the frame are aligned. Compared with the existing manual precise installation of the box plate on the pushing mechanism, the above-mentioned box plate can be roughly installed on the cantilever and the suction cup, and then the oblique frame on the box plate is used for automatic positioning along the frame. There is no need for the user to align the box plate with a large operating area and heavy weight when connecting it to the equipment, and instead, the easy-to-install oblique frame is used for auxiliary positioning. On the one hand, the operation is convenient and the difficulty of connecting the box plate to the equipment is reduced. On the other hand, the position of the box plate can be quickly adjusted after installation without the need for reciprocating disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Three notches 39 are provided on the side of the chassis 34, which are respectively connected to the three slots of the slide groove 37, and a cantilever 310 is movably arranged in the notch 39. A rotating shaft 311 is fixedly inserted into the cantilever 310, and the cantilever 310 is rotatably connected in the notch 39 through the rotating shaft 311.

[0050] A positioning assembly 315 is provided on the chassis 34 , the round seat 33 , the push rod 35 and the control frame 38 .

The push rod 35 is movably inserted into the through hole 3154, and a spiral groove 3156 matching the engaging block 3155 is provided on the surface of the push rod 35.

When the inspection pin 3152 reaches the front side of the frame, the chassis 34 rotates to align the cantilever 310 and the box plate with the frame, and the inspection pin 3152 bounces down along the frame to lock the rotating chassis 34.

[0054] A two-way centering component 3157 is provided on the cantilever 310, the suction cup 314 and the distribution box panel.

[0055] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, the bidirectional centering component 3157 includes a slide rail 31571 vertically slidably connected to the cantilever 310 , and a slide seat 31572 is laterally slidably connected to the slide rail 31571 , and the suction cup 314 is set on the slide seat 31572 .

[0056] The slide rail 31571 and the slide seat 31572 are both provided with an electromagnetic lock 31573 for locking themselves. After the electromagnetic lock 31573 is activated, it can lock the slide rail 31571 along the cantilever 310 and lock the slide seat 31572 along the slide rail 31571.

[0057] A magnetic base 31574 is provided on the inner side of the distribution box panel, and a shaft sleeve 31575 is fixedly provided on the magnetic base 31574, a ring base 31576 is rotatably connected to the shaft sleeve 31575, and four V-shaped inclined frames 31577 are fixedly provided on the outer ring of the ring seat 31576.

[0059] A time-delay locking member 31579 is provided between the shaft sleeve 31575 and the ring seat 31576 .

[0060] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, the delay locking member 31579 includes a knob rotatably set in the sleeve 31575, and a coil spring is set between the knob and the sleeve 31575, and a damping strip matching the knob is set on the inner side of the sleeve 31575.

[0063] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, the groove body of the spiral groove 3156 is configured to be composed of two symmetrical sections that are interconnected, so when the push rod 35 moves downward and utilizes the insert block to drive the control frame 38 to deflect, the control frame 38 performs reciprocating deflection.

[0064] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, a ball is embedded in the bottom end of the detection pin 3152, so that after the detection pin 3152 moves downward, it contacts the top of the distribution box frame using the ball, and reduces friction through the rolling of the ball during movement, which improves the smoothness of movement on the one hand and reduces ineffective wear on the other.

[0065] A method for using a welding processing table for preparing a distribution box comprises the following steps:

[0066] S1. Place the distribution box frame on the placement table 1 with the box opening facing the front, fix it with the electromagnet 2, and then fix the distribution box panel along the suction cup 314.

[0067] S2. Start the lifting frame 31 to drive the slide 32 and the round seat 33 to move downward. During this process, the push rod 35 contacts the top of the distribution box frame and moves upward along the round seat 33 under pressure. At this time, the control frame 38 moves upward synchronously with the push rod 35, and the oil smoke force arm 313 pushes the cantilever 310 to flip downward until the distribution box panel is attached to the distribution box frame. On the contrary, when the round seat 33 moves upward, the cantilever 310 flips upward and resets.

[0068] S3. When the distribution box frame is not placed correctly and is misaligned with the cantilever 310 and the distribution box panel, the detection pin 3152 is pressed down on the top of the distribution box frame, and the round seat 33 moves downward to push the push rod 35 to move upward in the opposite direction. The spiral groove 3156 on the surface of the rod body drives the control frame 38 and the chassis 34 to perform a certain amount of reciprocating rotation along the insert block, so that the inspection pin performs a synchronous circular motion. When the detection pin 3152 reaches the front side of the frame, the chassis 34 rotates to align the cantilever 310 and the box panel with the frame, and the detection pin 3152 bounces down along the frame to lock the rotating chassis 34. At this time, the push rod 35 can drive the control frame 38 to move upward to operate the cantilever 310.

[0069] S4. After the box plate is installed on the suction cup 314, the magnetic base 31574 is centered and adsorbed on the side of the box plate opposite to the frame. When the box plate is attached to the frame, the inclined frame 31577 is inserted into the frame and pushes the box plate in the opposite direction along the inner side thereof to perform horizontal and vertical displacement along the slide rail 31571 and the cantilever 310, so that the box plate is aligned with the frame.

5. A welding processing table for preparing a distribution box according to claim 1, characterized in that: Three auxiliary discs are distributed in an annular shape on the outer side of the suction cup (314).

6. A welding processing table for preparing a distribution box according to claim 2, characterized in that: The groove body of the spiral groove (3156) is configured to be composed of two symmetrical sections that are interconnected.

7. A welding processing table for preparing a distribution box according to claim 2, characterized in that: A ball is rotatably embedded in the bottom end of the detection pin (3152).

8. A method for using a welding processing table for preparing a distribution box, using the welding processing table for preparing a distribution box as described in any one of claims 1 to 7, characterized in that: The steps include: S1, placing the distribution box frame on the placement table (1) with the box opening facing the front, and then fixing it with the electromagnet (2), and then fixing the distribution box panel along the suction cup (314); S2, start the lifting frame (31) to drive the slide frame (32) and the round seat (33) to move downward. During this process, the push rod (35) contacts the top of the distribution box frame and is pressed to move upward along the round seat (33). At this time, the control frame (38) moves upward synchronously with the push rod (35), and the oil smoke force arm (313) pushes the cantilever (310) to flip downward until the distribution box panel is attached to the distribution box frame. On the contrary, when the round seat (33) moves upward, the cantilever (310) flips upward and resets; S3, when the distribution box frame is not placed correctly and misaligned with the cantilever (310) and the distribution box panel, the detection pin (3152) is pressed down on the top of the distribution box frame, and the round seat (33) moves down to push the push rod (35) to move up in the opposite direction. The spiral groove (3156) on the surface of the rod body drives the control frame (38) and the chassis (34) to reciprocate for a certain amount along the insert block, so that the inspection pin performs a synchronous circular motion. When the detection pin (3152) reaches the front side of the frame, the chassis (34) rotates to align the cantilever (310) and the box panel with the frame, and the detection pin (3152) bounces down along the frame to lock the rotating chassis (34). At this time, the push rod (35) can drive the control frame (38) to move up to operate the cantilever (310); S4. After the box plate is mounted on the suction cup (314), the magnetic base (31574) is centered and adsorbed on the side of the box plate opposite to the frame. When the box plate is attached to the frame, the inclined frame (31577) is inserted into the frame and pushes the box plate in the opposite direction along the inner side thereof to move horizontally and vertically along the slide rail (31571) and the cantilever (310), so that the box plate and the frame are aligned.
