[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 5 shown, the present invention provides an electronic welding process teaching device, including a main board 1. A plurality of installation slots 2 are inwardly opened on the side surface of the main board 1. Display boards 3 are inserted and fixed in the plurality of installation slots 2. Corresponding welding objects, welding operation diagrams, and two-dimensional codes for scanning and viewing welding videos are glued on the surface of each display board 3. And the sizes of each display board 3 and the installation slots 2 are changed according to different display processes. A transparent glass cover 4 is fixedly arranged around the side surface of each display board 3. The glass cover 4 completely covers the display objects glued on the display board 3 and is transparent for easy observation by personnel.

[0026] As Figures 2 to 4 shown, a fixing mechanism 5 with the same structure is arranged in each installation slot 2. The fixing mechanism 5 includes a rotating seat 51 fixed to the middle of the bottom of the installation slot 2 by screws. Four grooves are opened on the end surface of the rotating seat 51 away from the bottom of the installation slot 2. And lower connecting rods 52 are rotatably connected in the four grooves. Through grooves are formed in the middle of the four lower connecting rods 52. The upper connecting rods 54 are rotatably connected to the ends of the four lower connecting rods 52 away from the rotating seat 51. And the through grooves in the middle of the lower connecting rods 52 reserve space for the rotation of the upper connecting rods 54. The upper connecting rods 54 are rotatably connected to an abutting block 53 at the ends away from the lower connecting rods 52. One end surface of the abutting block 53 facing the display board 3 is conical. And an inserting rod 55 is fixedly arranged in the middle of the side of the abutting block 53 facing the rotating seat 51. A jack 58 is opened at the position of the rotating seat 51 aligned with the inserting rod 55. And the inner wall of the jack 58 and the inserting rod 55 are movably inserted.

[0027] It should be noted that a fixing groove 12 is provided inside each display board 3. A through hole is provided through the side wall on the side of the fixing groove 12 close to the abutting block 53, and the width of the through hole is 4-5 cm larger than the width of the abutting block 53, so as to ensure that the abutting block 53, the upper connecting rod 54 and the lower connecting rod 52 that have not been fully unfolded can be inserted into the fixing groove 12.

[0028] As Figure 4 , 5 shown, four grooves are circumferentially provided on the end surface of the insertion rod 55 after passing through the insertion hole 58, and a clamping block 57 is rotatably connected in each of the four grooves. One side of the clamping block 57 is trapezoidally protruded, and a first spring 56 is fixedly connected to the groove of the insertion rod 55 on the side of the protrusion of the clamping block 57. One end of the first spring 56 away from the insertion rod 55 is fixedly connected to the side surface of the clamping block 57. Under normal conditions, the clamping block 57 protrudes from the surface of the insertion rod 55 under the elastic force of the first spring 56. A lock hole 6 is provided at the bottom of the installation groove 2 at a position aligned with the insertion rod 55. The lock hole 6 has the same width as the insertion hole 58 and is aligned. T-shaped grooves 7 are provided at positions on the inner wall of the lock hole 6 aligned with the four clamping blocks 57, and the width of the T-shaped groove 7 is the same as the width of the clamping block 57.

[0029] As Figure 5 shown, bottom grooves 8 are provided on the other side surfaces of the main board 1 relative to the plurality of lock holes 6. Four through holes are provided at the bottom of the bottom grooves 8 and communicated with one end of the T-shaped opening of the T-shaped groove 7. A pressing plate 9 is movably inserted into the bottom grooves 8. Reset blocks 10 are fixedly provided on the side walls of the pressing plate 9 facing the groove of the T-shaped groove 7. The reset blocks 10 are integrally L-shaped, and under normal conditions, the protruding parts of the reset blocks 10 are inserted into one side of the groove of the T-shaped groove 7. A second spring 11 is fixedly connected to the L-shaped end of the reset block 10, and one end of the second spring 11 away from the reset block 10 is fixedly connected to the bottom of the T-shaped groove 7.

[0030] The principle and process of the present utility model:

[0031] When using this device, insert the display board 3 into the installation groove 2 in such a way that the opening of the fixing groove 12 is aligned with the abutting block 53. When the conical top of the abutting block 53 abuts against the bottom of the fixing groove 12, the upper connecting rod 54 and the lower connecting rod 52 are in a state of being closely inserted with the inserting rod 55 in a retracted state, and at this time, a part of the upper connecting rod 54 is located inside the fixing groove 12. As the display board 3 continues to be inserted, the bottom of the fixing groove 12 applies pressure to the abutting block 53, and then the abutting block 53 transmits the pressure to the upper connecting rod 54. The upper connecting rod 54 receives the pressure and transmits it to the lower connecting rod 52. The lower connecting rod 52 rotates and unfolds with the rotating seat 51 as the rotation point. At the same time, the upper connecting rod 54 unfolds synchronously with the abutting block 53 as the rotation point, so that the lower connecting rod 52 and the upper connecting rod 54 extend outward from their connection points, so that the distance between the connection points of the four lower connecting rods 52 and the upper connecting rod 54 is greater than the width of the through hole of the fixing groove 12, so that the whole inserting rod 55 is horizontally fixed to the display board 3.

[0032] As the display board 3 is inserted, while the inserting rod 55 is fixed, the bottom of the inserting rod 55 is pushed and inserted into the locking hole 6. During the insertion process, the clamping block 57 is abutted inside the locking hole 6 and thus located in the side groove 59. When the end of the inserting rod 55 abuts against the bottom of the locking hole 6, the clamping block 57 is located in the T-shaped groove 7, thus canceling the extrusion of the clamping block 57. Then, the clamping block 57 is pushed by the first spring 56, so that the L-shaped protrusion of the clamping block 57 is clamped in the T-shaped groove 7, so that the whole inserting rod 55 is inserted and fixed in the locking hole 6 to form longitudinal fixation, cooperating with the overall insertion effect of the installation groove 2 and the display board 3, so that the display board 3 is fixed on the surface of the main board 1, facilitating the display of the welding process and being conducive to observation.

[0033] When replacing the display board 3, apply a thrust to the pressing plate 9 to press the pressing plate 9 into the bottom groove 8. As the pressing plate 9 is pressed in, the four reset blocks 10 are pressed into the T-shaped groove 7, so as to apply an extrusion force to the L-shaped convex block of the clamping block 57 and press the clamping block 57 back into the side groove 59. Then, the operator directly applies a pulling force to the display board 3 for disassembly. Then, the operator stops applying a thrust to the pressing plate 9, and the second spring 11 stops being pressured and thus rebounds, applying a thrust to the reset block 10, so as to push the pressing plate 9 back to the initial position, thereby facilitating the operator to replace the display board 3.
