[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0035] Example 1: As Figures 1 to 5 shown, a welding fixture for a cooker panel according to an embodiment of the present invention includes a clamping assembly and a driving assembly provided on a base 1;

[0036] The clamping assembly is composed of a support mechanism and a clamping mechanism. The support mechanism includes a pair of turntables 2, the turntables 2 are rotatably arranged in arc-shaped grooves at the top of the base 1, and the two turntables 2 are fixedly connected in the middle by a support rod 3. The clamping mechanism includes a pair of mounting frames 5 arranged up and down. A plurality of rotating shafts 9 are respectively installed on the mounting frames 5 on the upper and lower sides, and rubber rollers 4 are rotatably installed on the rotating shafts 9;

[0037] The driving assembly is arranged on the turntable 2. The driving assembly includes a first connecting block 20 and a second connecting block 22. Fixed plates 13 are fixed on the sides of the mounting frames 5 on the upper and lower sides. A first connecting block 20 is fixed on the side of the fixed plate 13. The first connecting block 20 penetrates through a through groove 26 opened on the turntable 2. A second connecting block 22 is fixed on the side wall of the turntable 2. A bidirectional lead screw 23 is rotatably installed in the middle of the second connecting block 22. The first connecting blocks 20 on the upper and lower sides are respectively threadedly connected to both ends of the bidirectional lead screw 23;

[0038] It further includes a limiting assembly arranged inside the base 1 to limit the rotation of the turntable 2.

[0039] During operation, first place both ends of the stove top panel on the lower rubber rollers 4, and support the stove top panel through the rubber rollers 4. The rubber rollers 4 can rotate on the rotating shaft 9, and then change the position by pushing the stove top panel, facilitating the adjustment of the clamping position of the stove top panel. Then, rotate the bidirectional lead screw 23 through the handle. The bidirectional lead screw 23 drives the connecting blocks one 20 on the upper and lower sides to move towards the middle synchronously, and then drives the fixing plate 13, the mounting bracket 5, the rotating shaft 9 and the rubber rollers 4 to move synchronously, so that the upper and lower rubber rollers 4 are clamped on the upper and lower sides of the stove top panel, in order to clamp and limit the stove top panel, facilitating the welding work of the stove top panel. In addition, the rubber rollers 4 are made of elastic rubber or silicone material to avoid damaging the surface of the stove top panel during the clamping process;

[0040] Support the two turntables 2 through the support rods 3. In addition, limit the turntables 2 through the clamping and limiting components. Then, force can be applied to the turntables 2 through the support rods 3, so that the turntables 2 rotate in the arc-shaped grooves, in order to change the inclination angle of the fixture, thereby changing the inclination angle of the stove top panel, meeting more welding requirements, and then improving the processing efficiency and accuracy;

[0041] In addition, a space allowing the stove top panel to move left and right is reserved on the rubber rollers 4. Cooperating with the rubber rollers 4 clamped up and down, it is convenient to clamp and fix stove top panels of different sizes, with a wider application range.

[0042] As Figure 2 and 3 As shown, a first chute is provided in the middle of the mounting bracket 5. The rotating shaft 9 is movably arranged in the first chute. Anti-detachment blocks are respectively arranged at both ends of the rotating shaft 9. One end of the rotating shaft 9 is threadedly connected with a nut 10. One end of the rotating shaft 9 is clamped on the mounting bracket 5 through the anti-detachment block and the nut 10. During operation, loosen the nut 10 by rotation, and then the rotating shaft 9 can move horizontally along the first chute, in order to adjust the positions of the rotating shaft 9 and the rubber rollers 4, thereby changing the contact position between the rubber rollers 4 and the stove top panel. In this way, the clamping position can be changed according to needs, avoiding the rubber rollers 4 blocking the welding position.

[0043] As Figure 3 As shown, a fixing block 14 is fixed on the rotating shaft 9. The fixing block 14 is rectangular, and the side of the fixing block 14 fits the inner wall of the first chute. During operation, set the fixing block 14 to limit the rotation of the rotating shaft 9. In this way, when the nut 10 is rotated to tighten or loosen, the rotating shaft 9 will not rotate together, making the operation more convenient.

[0044] As Figure 5As shown in the figure, a movable frame 8 is provided on the side of the mounting frame 5. A telescopic sleeve 6 is fixed between the mounting frame 5 and the movable frame 8. The telescopic sleeve 6 is composed of a piston rod and a sleeve. The piston rod is hermetically and slidably connected to the inner wall of the sleeve through a piston head. A first spring 7 is sleeved on the telescopic sleeve 6. A second chute is provided in the middle of the movable frame 8. One end of the rotating shaft 9 away from the mounting frame 5 penetrates through the second chute. The rubber roller 4 is arranged on the side of the movable frame 8 away from the mounting frame 5. Elastic blocks 24 are respectively installed on the upper and lower sides of the second connecting block 22. A cavity is provided in the middle of the elastic block 24, and the cavity is filled with air. The inside of the elastic block 24 is communicated with the inside of the telescopic sleeve 6 through a connecting pipe 25. During operation, the movable frame 8 is supported by the telescopic sleeves 6 and the first springs 7 on both sides, so that the movable frame 8 is stably maintained on the side of the mounting frame 5. The rotating shaft 9 is supported by the movable frame 8 to improve the stability of the rotating shaft 9. When the first connecting blocks 20 on the upper and lower sides approach each other, the elastic blocks 24 are squeezed by the first connecting blocks 20 and the second connecting blocks 22. The elastic blocks 24 are deformed, and the air inside the elastic blocks 24 is introduced into the inner cavity of the telescopic sleeve 6 through the connecting pipe 25, thereby pushing the piston rod to move outwards, so that the movable frame 8 moves away from the mounting frame 5. Furthermore, the rubber roller 4 is squeezed by the movable frame 8 and the anti - detachment block, and the rubber roller 4 is limited. When the rubber roller 4 clamps the cooker panel, it is not easy to rotate, so that the clamping is more stable.

[0045] As Figure 3 shown, a steel ring 15 and an elastic ring 16 are sleeved on the rotating shaft 9. The elastic ring 16 is an elastic rubber ring. A plurality of steel rings 15 and elastic rings 16 are provided, and they are alternately and spacedly distributed on the rotating shaft 9. The rubber roller 4 is sleeved outside the steel rings 15 and the elastic rings 16. During operation, the steel rings 15 and the elastic rings 16 are squeezed by the movable frame 8 and the anti - detachment block, so that the elastic ring 16 is deformed and abuts against the inner wall of the rubber roller 4, further limiting the rubber roller 4.

[0046] As Figure 5 shown, limiting hoops 11 are respectively sleeved on both ends of the upper and lower mounting frames 5. A second spring 12 is installed between the upper and lower fixing plates 13. The limiting hoop 11 is fixedly connected to the turntable 2 through a connecting plate. During operation, the strength of the device is increased by setting the limiting hoops 11 and the connecting plate, making the device more stable, so as to extend the service life of the device. The upper and lower mounting frames 5 are made more stable by setting the second spring 12.

[0047] As Figure 5As shown in the figure, the limiting component includes a limiting rod 18. An activity cavity 17 is provided inside the base 1. The limiting rod 18 is slidably arranged in the activity cavity 17. The limiting rod 18 is arranged in an L shape. Claw slots 29 are evenly distributed on the side of the turntable 2. One end of the limiting rod 18 vertically extends to the bottom of the turntable 2 and is inserted into the claw slot 29. The other end of the limiting rod 18 horizontally extends to the outside of the base 1. An elastic member 19 is fixed at the bottom of the limiting rod 18. During operation, the two turntables 2 are rotatably arranged in the arc-shaped slots to limit the turntable 2. Step on the limiting rod 18 downward with the foot to make the top end of the limiting rod 18 disengage from the claw slot 29, and then rotate the turntable 2 to adjust the inclination angle of the fixture, and then change the inclination angle of the stove panel to meet more usage requirements. Finally, the elastic member 19 rebounds to make the limiting rod 18 reset and be clamped in the claw slot 29 to limit the turntable 2 again. Using the method of stepping with the foot can free both hands and facilitate operation.

[0048] Embodiment 2: As Figure 5 shown in the figure, compared with Embodiment 1, another implementation manner of the present invention is: a ring 27 is fixed on the outer wall edge of the turntable 2, and an arc-shaped baffle 28 is fixed on the inner wall of the end of the arc-shaped slot at the top of the base 1. The baffle 28 is attached to the inner side of the ring 27. During operation, the ring 27 can rotate around the bottom of the baffle 28. By providing the baffle 28, the ring 27 is limited to prevent the device from disengaging from the arc-shaped slot upward, so as to stably install the device in the arc-shaped slot. By removing the bolt connecting the baffle 28 and the base 1, the baffle 28 can be taken out, and then the fixture as a whole can be taken out of the arc-shaped slot, which is convenient for maintenance and repair.

[0049] A usage method of a stove panel welding fixture, which uses the above-mentioned stove panel welding fixture, includes the following steps:

[0050] S1. Place the stove panel above the rubber roller 4 located below. By rolling the rubber roller 4, adjust the clamping position of the stove panel. Rotate the bidirectional lead screw 23 to drive the upper and lower connecting blocks one 20, the mounting frame 5, the rotating shaft 9, and the rubber roller 4 to move synchronously towards the middle to clamp and fix the stove.

[0051] S2. The connecting block one 20 and the connecting block two 22 approach each other, squeeze the elastic block 24, and press the air inside the elastic block 24 into the telescopic sleeve 6 through the connecting pipe 25, pushing the movable frame 8 to move away from the mounting frame 5, and then squeezing the rubber roller 4 to limit the rubber roller 4 so that the rubber roller 4 stably clamps the stove panel.

[0052] S3. Through the movable frame 8 and the anti-disengagement block, squeeze the steel ring 15 and the elastic ring 16, so that the elastic ring 16 deforms and abuts against the inner wall of the rubber roller 4 to further limit the rubber roller 4.

[0053] S4. Press down the limit rod 18 so that the top of the limit rod 18 disengages from the card slot 29, then rotate the turntable 2 to adjust the inclination angle of the fixture, and then change the inclination angle of the cooking appliance panel to meet more usage requirements. Finally, reset the limit rod 18 and snap it into the card slot 29 to limit the turntable 2 again.

[0054] The above front, back, left, right, up, and down are all based on the Figure 1 description in the accompanying drawings of the specification. Taking the perspective of the observer as the standard, the side of the device facing the observer is defined as the front, and the left side of the observer is defined as the left, and so on.
