[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Example 1: Figures 1 to 5 As shown, a stove panel welding fixture 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 consists of a support mechanism and a clamping mechanism. The support mechanism includes a pair of turntables 2, which are rotatably arranged in the arc-shaped groove on the top of the base 1. The two turntables 2 are fixedly connected by a support rod 3 in the middle. The clamping mechanism includes a pair of mounting frames 5 arranged upper and lower. A plurality of rotating shafts 9 are respectively installed on the upper and lower mounting frames 5. The rubber rollers 4 are rotatably installed on the rotating shafts 9.

[0037] The drive assembly is arranged on the turntable 2, and the drive assembly includes a connecting block 1 20 and a connecting block 2 22. The sides of the mounting frame 5 on the upper and lower sides are fixed with a fixing plate 13, and the side of the fixing plate 13 is fixed with a connecting block 1 20. The connecting block 1 20 passes through the through slot 26 opened on the turntable 2, and the connecting block 2 22 is fixed on the side wall of the turntable 2. A bidirectional screw rod 23 is rotatably installed in the middle of the connecting block 22, and the connecting blocks 1 20 on the upper and lower sides are respectively threadedly connected to the two ends of the bidirectional screw rod 23;

[0038] It also includes a limiting component arranged inside the base 1, which limits the rotation of the turntable 2.

[0039] During operation, the two ends of the stove panel are first overlapped on the rubber rollers 4 located below, and the stove panel is supported by the rubber rollers 4. The rubber rollers 4 can rotate on the rotating shaft 9, and then the position of the stove panel is changed by pushing the stove panel, which facilitates the adjustment of the clamping position of the stove panel; then the two-way screw rod 23 is rotated by the handle, and the two-way screw rod 23 drives the upper and lower connecting blocks 20 to move synchronously toward the middle, thereby driving the fixing plate 13, the mounting frame 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 panel, so as to clamp the stove panel and limit the position, which is convenient for welding the stove panel; in addition, the rubber rollers 4 are made of elastic rubber or silicone material to avoid damaging the surface of the stove panel during the clamping process;

[0040] The turntable 2 on both sides is supported by the support rods 3. In addition, the turntable 2 is limited by the clamping limit assembly. Then, the support rods 3 can be used to apply force to the turntable 2, so that the turntable 2 rotates in the arc groove, thereby changing the inclination angle of the clamp, thereby changing the inclination angle of the cooktop panel, meeting more welding requirements, and thus improving processing efficiency and precision.

[0041] In addition, a space is reserved on the rubber roller 4 to allow the stove panel to move left and right. The rubber roller 4 is clamped up and down to clamp stove panels of different sizes, which has a wider range of applications.

[0042] like Figure 2 and 3 As shown, a slide groove 1 is provided in the middle of the mounting frame 5, and the rotating shaft 9 is movably arranged in the slide groove 1. Anti-slip blocks are respectively provided at both ends of the rotating shaft 9. A nut 10 is threadedly connected to one end of the rotating shaft 9, and one end of the rotating shaft 9 is clamped on the mounting frame 5 through the anti-slip block and the nut 10; when working, the nut 10 is loosened by rotation, so that the rotating shaft 9 can move laterally along the slide groove 1, so as to adjust the position of the rotating shaft 9 and the rubber roller 4, thereby changing the contact position of the rubber roller 4 and the stove panel, so that the clamping position can be changed as needed to avoid the rubber roller 4 blocking the welding position.

[0043] like Figure 3 As shown, a fixed block 14 is fixed on the rotating shaft 9, and the fixed block 14 is set to be rectangular. The side of the fixed block 14 is in contact with an inner wall of the slide groove. When working, the fixed block 14 is set to limit the rotation of the rotating shaft 9. In this way, when the nut 10 is tightened or loosened by rotation, the rotating shaft 9 will not rotate together, so that the operation is more convenient.

[0044] like Figure 5As shown, a movable frame 8 is provided on the side of the mounting frame 5, and 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 sealed and slidably connected to the inner wall of the sleeve through the piston head. A spring 1 7 is sleeved on the telescopic sleeve 6. A slide groove 2 is provided in the middle of the movable frame 8. The end of the rotating shaft 9 away from the mounting frame 5 passes through the slide groove 2. 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 connecting block 22. A cavity is provided in the middle of the elastic block 24, and the cavity is filled with air. The interior of the elastic block 24 is connected to the interior of the telescopic sleeve 6 through the connecting pipe 25; when working, through the two The telescopic sleeve 6 and spring 1 7 on the side support the movable frame 8, so that the movable frame 8 is stably maintained on the side of the mounting frame 5, and the rotating shaft 9 is supported by the movable frame 8 to improve the stability of the rotating shaft 9; when the connecting blocks 1 20 on the upper and lower sides move toward the middle, the elastic block 24 is squeezed by the connecting block 1 20 and the connecting block 2 22, and the elastic block 24 is deformed, and the air inside the elastic block 24 is introduced into the inner cavity of the telescopic sleeve 6 through the connecting pipe 25, thereby pushing the piston rod to move outward, so that the movable frame 8 moves away from the mounting frame 5, and then the rubber roller 4 is squeezed by the movable frame 8 and the anti-slip block to limit the rubber roller 4. The rubber roller 4 is not easy to rotate when clamping the stove panel, thereby making the clamping more stable.

[0045] like Figure 3 As shown, the rotating shaft 9 is provided with a steel ring 15 and an elastic ring 16, and the elastic ring 16 is an elastic rubber ring. There are multiple steel rings 15 and elastic rings 16, which are alternately distributed on the rotating shaft 9. The rubber roller 4 is sleeved on the outside of the steel ring 15 and the elastic ring 16; when working, the steel ring 15 and the elastic ring 16 are squeezed by the movable frame 8 and the anti-slip block, so that the elastic ring 16 is deformed and pressed against the inner wall of the rubber roller 4, further limiting the rubber roller 4.

[0046] like Figure 5 As shown, both ends of the upper and lower mounting frames 5 are respectively provided with limiting hoops 11, and a second spring 12 is installed between the upper and lower fixing plates 13, and the limiting hoops 11 are fixedly connected to the turntable 2 through a connecting plate; when working, the strength of the device is increased by arranging the limiting hoops 11 and the connecting plate, making the device more stable so as to extend the service life of the device; and the second spring 12 is provided to make the upper and lower mounting frames 5 more stable.

[0047] like Figure 5As shown, the limit assembly includes a limit rod 18, an active cavity 17 is opened inside the base 1, and the limit rod 18 is slidably arranged in the active cavity 17, and the limit rod 18 is set to be L-shaped, and the sides of the turntable 2 are evenly provided with card slots 29, one end of the limit rod 18 extends vertically to the bottom of the turntable 2 and is plugged into the card slot 29, and the other end of the limit rod 18 extends horizontally to the outside of the base 1, and an elastic member 19 is fixed to the bottom of the limit rod 18; when working, the turntables 2 on both sides are rotated and arranged in the arc groove to limit the turntable 2; the limit rod 18 is pressed downward by the foot to make the top end of the limit rod 18 disengage from the card slot 29, and then the turntable 2 is rotated to adjust the tilt angle of the clamp, and then the tilt angle of the stove panel is changed to meet more usage needs, and finally the limit rod 18 is reset and connected to the card slot 29 by the elastic member 19 to limit the turntable 2 again; using the foot-stepping method can free both hands and facilitate operation.

[0048] Example 2: Figure 5 As shown, compared with Example 1, another embodiment of the present invention is: a circular ring 27 is fixed to the edge of the outer wall of the turntable 2, and an arc-shaped baffle 28 is fixed on the inner wall of the end of the arc-shaped groove at the top of the base 1, and the baffle 28 is fitted on the inner side of the circular ring 27; when working, the circular ring 27 can rotate around the bottom of the baffle 28, and the baffle 28 and the ring 27 are limited by setting the baffle 28 to prevent the device from escaping from the arc-shaped groove upward, so that the device can be stably installed in the arc-shaped groove; by removing the bolts connecting the baffle 28 and the base 1, the baffle 28 can be removed, and then the entire clamp can be removed from the arc-shaped groove, which is convenient for maintenance and repair.
