[0033] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 2As shown, a liner clamping device is used for aligning the liner upper ring 100 and the liner lower ring 200, comprising: a processing base 1; an upper ring clamping mechanism 22, which is arranged on the processing base 1, and is used to position the liner upper ring 100; and a lower ring clamping mechanism 21, which is arranged on the processing base 1, and is used to position the liner lower ring 200; wherein, the upper ring clamping mechanism 22 comprises: an upper ring fixing unit 221, which comprises an upper ring inner wall support plate 2211 for supporting the liner upper ring 100 and an upper ring fixing plate 2212 for fixing the liner upper ring 100; and a connecting and clamping unit 222, which is movably arranged on the upper ring fixing unit 221, and is used to clamp the overlapping area formed by the overlap between the liner upper ring 100 and the liner lower ring 200.

[0035] Furthermore, the inner liner clamping device also includes: a movable plate moving mechanism 23, which has a movable plate 1 231 and a movable plate 232 movably arranged on the processing base 1, and is used to drive the upper circle clamping mechanism 22 and the lower circle clamping mechanism 21 to move left and right; the upper circle clamping mechanism 22 is divided into an upper circle clamping unit 1 224 and an upper circle clamping unit 2 225; the lower circle clamping mechanism 21 is divided into a lower circle clamping unit 1 216 and a lower circle clamping unit 2 217; the upper circle clamping unit 1 224 and the lower circle clamping unit 1 216 are arranged on the movable plate 1 231, and the upper circle clamping unit 2 225 and the lower circle clamping unit 2 217 are arranged on the movable plate 232.

[0036] Furthermore, the inner liner clamping device is movably arranged on the processing base 1 through a movable plate moving mechanism 23, and the movable plate moving mechanism 23 at least has a movable plate slide rail 235 arranged on the processing base 1, a movable plate 1 231 and a movable plate 232 slidingly arranged on the movable plate slide rail 235, and a movable plate driving member 1 2121 and a movable plate driving member 2 2131 respectively used to drive the movable plate 1 231 and the movable plate 2 232. The working principle of the movable plate driving member 2 2131 is the same as the working principle of the movable plate driving member 1 2121. Because the structures of the upper circle clamping unit 1 224 and the upper circle clamping unit 2 225, and the lower circle clamping unit 1 216 and the lower circle clamping unit 2 217 are symmetrical, only one group of units is explained here.

[0037] After adding the movable plate moving mechanism 23, the inner shell clamping device can be suitable for oven inner shells of different lengths. When the length of the oven inner shell to be welded changes, the distance between the upper circle clamping unit 1 224 and the upper circle clamping unit 2 225 and the distance between the lower circle clamping unit 1 216 and the lower circle clamping unit 2 217 can be adjusted to adapt to the length of the oven inner shell.

[0038] like Figure 3 and Figure 4As shown, the lower circle clamping unit 1 216 is also arranged on the movable plate 1 231 through the clamping plate moving mechanism 1 233, and the lower circle clamping unit 217 is also arranged on the movable plate 232 through the clamping plate moving mechanism 234. When the width of the oven inner tank to be welded changes, the distance between the upper circle clamping unit 1 224 and the distance between the lower circle clamping unit 1 216 and the upper circle clamping unit 225 and the lower circle clamping unit 2 217 can be adjusted by the clamping plate moving mechanism 1 233 and the clamping plate moving mechanism 2 234 to adapt to the width of the oven inner tank.

[0039] When the model of the oven liner is changed, the position of the liner clamping device on the processing base 1 can be adjusted, and after the specific position is determined, the position of the liner clamping device will not be changed in the subsequent welding process.

[0040] like Figure 3 and Figure 4 As shown, the lower circle clamping unit 1 216 or the lower circle clamping unit 2 217 includes: a lower circle clamping plate 211, which is arranged on the processing base 1; a lower circle upper and lower fixing unit 212, which includes a driving member 1 2121 and an upper and lower fixing member 2122 arranged at the output end of the driving member 1 2121; a lower circle left and right fixing unit 213, which includes a driving member 2131, and a left and right fixing member 2132 arranged at the output end of the driving member 2131, and the end sides of the left and right fixing members 2132 are hinged on the lower circle clamping plate 211; And the front and rear fixing units 214 of the lower circle, which include a driving member three 2141 and a front and rear fixing member 2142 arranged at the output end of the driving member three 2141; and a lower circle inner wall support plate 215, which is arranged on the processing base 1; wherein the lower circle upper and lower fixing units 212, the lower circle left and right fixing units 213 and the lower circle front and rear fixing units 214 are all arranged on the lower circle clamping plate 211; the left and right fixing members 2132 and the front and rear fixing members 2142 all cooperate with the lower circle inner wall support plate 215 to clamp the inner liner lower circle 200.

[0041] Furthermore, the structures of the lower ring clamping unit 1 216 and the lower ring clamping unit 2 217 are symmetrical, and are respectively used to clamp the left and right sides of the inner liner lower ring 200 and fix the two corners of the inner liner lower ring 200. Here, only the working mode of the lower ring clamping unit 1 216 is described.

[0042] Furthermore, after the lower ring clamping unit 216 clamps the inner liner lower ring 200, the bottom edge of the inner liner lower ring 200 is fixed in the groove of the clamping base plate 238 of the clamping plate moving mechanism 233, and its inner wall is against the lower ring inner wall support plate 215. The lower ring inner wall support plate 215 is also fixedly set on the clamping base plate 238. The lower ring inner wall support plate 215 has an arc-shaped surface adapted to the corner of the inner liner lower ring 200, and extends outward along both sides of the arc-shaped surface to form a support part 1. The two support parts 1 are respectively used to support the left and right side walls and the bottom wall of the inner liner lower ring 200. The left and right side walls of the inner liner lower ring 200 are in the same plane as the welding point, and the bottom wall of the inner liner lower ring 200 is connected to the two side walls.

[0043] Specifically, the driving member 2121 can drive the upper and lower fixing members 2122 to flip, so that the upper and lower fixing members 2122 cooperate with the clamping base plate 238 to clamp the lower ring 200 of the inner liner up and down, thereby fixing it in the up and down directions.

[0044] The second driving member 2131 is arranged on the side wall of the lower ring clamping plate 211, which can drive the left and right fixing members 2132 to flip and move. The left and right fixing members 2132 include a long strip 2134 and left and right fixing blocks 2133 arranged on the upper and lower sides of the long strip 2134. The length of the long strip 2134 is adapted to the height of the lower ring 200 of the inner liner. The long strip 2134 is used to drive the left and right fixing blocks 2133 to move. The left and right fixing members 2132 cooperate with the lower ring inner wall support plate 215 to clamp and fix the lower ring 200 of the inner liner to the left and right. The end sides of the left and right fixing blocks 2133 are hinged on the lower ring clamping plate 211, which provides a rotation fulcrum for the left and right fixing blocks 2133 and increases its stability during rotation.

[0045] The number of driving member three 2141 and front and rear fixing members 2142 are both set to two, and are respectively arranged on the upper and lower sides of driving member two 2131. Driving member three 2141 can drive the front and rear fixing members 2142 to move toward the lower circle of the inner liner 200. The front and rear fixing members 2142 can also cooperate with the inner wall support plate 215 of the lower circle to fix the lower circle of the inner liner 200 in the front and rear directions. Through the joint cooperation of various fixing units, the stability of the placement of the lower circle of the inner liner 200 can be improved, thereby improving the stability during welding.

[0046] The upper and lower fixing members 2122, the left and right fixing members 2132 and the front and rear fixing members 2142 are all made of rubber material, or the parts where they abut against the lower ring 200 of the inner liner are made of rubber material, which can ensure that the lower ring 200 of the inner liner is not damaged.

[0047] like Figure 5-7As shown, the upper ring clamping mechanism 22 includes: an upper ring fixing unit 221, which includes an upper ring inner wall support plate 2211 for supporting the inner liner upper ring 100 and an upper ring fixing plate 2212 for fixing the inner liner upper ring 100; and a connecting clamping unit 222, which is movably arranged on the upper ring fixing unit 221, and is used to clamp the overlapping area formed by the overlapping of the inner liner upper ring 100 and the inner liner lower ring 200.

[0048] Furthermore, in order to cooperate with the lower ring clamping mechanism 21 to adapt to different models of oven liners, the upper ring clamping mechanism 22 can also be divided into an upper ring clamping unit 1 224 and an upper ring clamping unit 2 225. The upper ring clamping unit 1 224 and the upper ring clamping unit 2 225 are respectively arranged on the movable plate 1 231 and the movable plate 2 232. The structures of the upper ring clamping unit 1 224 and the upper ring clamping unit 2 225 are symmetrical and can both be moved on the processing base 1. Here, only the working principle of the upper ring clamping unit 1 224 is introduced.

[0049] Furthermore, when it is necessary to process and weld oven inner shells of different models, it is necessary to adjust the distance between the upper ring clamping unit 1 224 and the upper ring clamping unit 2 225. When the upper ring clamping unit 1 224 and the upper ring clamping unit 2 225 move, it is necessary to ensure that they move on the same horizontal line without deviating. Therefore, a guide unit 226 is provided on the upper ring clamping unit 1 224 and the upper ring clamping unit 2 225.

[0050] The guide unit 226 at least comprises a guide base 2261 arranged on the upper circle clamping unit 224, a guide base 2262 arranged on the upper circle clamping unit 225, and a guide rod 2263 inserted in the guide base 2261 and the guide base 2262. The front end of the guide rod 2263 is fixedly arranged in the guide base 2261, and the rear end thereof is movably inserted in the guide base 2262. The guide unit 226 can ensure that the upper circle clamping unit 224 and the upper circle clamping unit 225 move on the same horizontal line without deviation, thereby ensuring the stability of the upper circle fixing plate 2212 clamping the upper circle 100 of the inner liner.

[0051] like Figure 5-8As shown, the upper circle clamping unit 224 at least comprises an upper circle fixing plate 2212 rotatably arranged on the processing base 1 and an upper circle inner wall support plate 2211 arranged on the processing base 1, the upper circle fixing plate 2212 has an upper circle fixing groove 2213 for fixing the liner upper circle 100, when the liner upper circle 100 is placed in the upper circle fixing groove 2213, the bottom edge of the liner upper circle 100 abuts against the upper circle fixing groove 2213, the upper circle fixing driving member arranged on the top of the upper circle fixing plate 2212 can drive the upper circle fixing member to clamp and fix the liner upper circle 100, so that it can follow the upper circle fixing plate 2212 to flip and approach the liner lower circle 200, when the liner upper circle 100 is aligned with the liner lower circle 200, the upper circle fixing plate 2212 can cooperate with the upper circle inner wall support plate 2211 to clamp and fix the liner upper circle 100 in the front and rear directions.

[0052] The upper ring inner wall support plate 2211 has an arc-shaped surface adapted to the corner of the inner liner upper ring 100, and extends outward along both sides of the arc-shaped surface to form a second support part, and the two support parts are respectively used to support the left and right side walls and the bottom wall of the inner liner upper ring 100.

[0053] Furthermore, the connecting and clamping unit 222 is used to clamp the inner liner upper ring 100 and the inner liner lower ring 200 beside the overlapping area to increase the stability during welding. When the connecting and clamping unit 222 is working, it cooperates with the upper ring inner wall support plate 2211 to clamp and fix the overlapping area, which can ensure that the inner liner upper ring 100 and the inner liner lower ring 200 at the overlapping area are aligned and not misaligned. The connecting and clamping unit 222 also has a welding gap 2225 for rolling welding. The connecting and clamping unit 222 can effectively improve the product yield of the oven liner. At the same time, the connecting and clamping unit 222 can move with the upper ring fixing plate 2212. When the upper ring fixing plate 2212 is flipped to the working position, the connecting and clamping unit 222 completes the clamping work by adjusting its own position.

[0054] like Figure 7 and Figure 8 As shown, the connecting pressing unit 222 includes: a pressing plate body 2221, which is movably arranged on the upper circle fixing plate 2212; a pressing plate driving member 2222, which is used to drive the pressing plate body 2221 to work; a pressing plate base 2226, which is arranged on the upper circle fixing plate 2212; and a pressing plate rotating arm 2227, whose rear end is connected to the output end of the pressing plate driving member 2222, the front end is connected to the pressing plate body 2221, and the middle part is hinged on the upper circle fixing plate 2212.

[0055] The clamping plate body 2221 has a first abutting portion 2223 and a second abutting portion 2224, and a welding gap 2225 is defined between the first abutting portion 2223 and the second abutting portion 2224. The first abutting portion 2223 movably abuts against the upper circle 100 of the inner liner, and the second abutting portion 2224 movably abuts against the lower circle 200 of the inner liner.

[0056] like Figure 7 and Figure 8 As shown, the top and bottom edges of the abutment portion 1 2223 and the abutment portion 2 2224 are connected to each other, and the middle portion is hollowed out to form a welding gap 2225. When the clamping plate body 2221 is against the oven inner pot, the welding gap 2225 is opposite to the overlapping area between the inner pot upper circle 100 and the inner pot lower circle 200. The rolling welding wheel can be placed in the welding gap 2225 and weld the overlapping area. At this time, the abutment portion 1 2223 and the abutment portion 2 2224 respectively cooperate with the upper circle inner wall support plate 2211 to clamp and fix the inner pot upper circle 100 and the inner pot lower circle 200.

[0057] Furthermore, in order to cooperate with the abutment part 1 2223 and the abutment part 2 2224 to clamp the inner liner upper ring 100 without affecting the roll welding, a long groove 2214 aligned with the welding gap 2225 is opened on the upper ring inner wall support plate 2211, and two roll welding wheels pass through the welding gap 2225 and the long groove 2214 to roll weld the overlapping area respectively.

[0058] like Figure 7 and Figure 8 As shown, the clamping plate body 2221 is movably arranged on the upper ring fixing plate 2212, and it has an independent driving source that allows it to move freely, so that the clamping plate body 2221 can abut against or separate from the oven inner tank, and it is hinged to the upper ring fixing plate 2212 through a clamping plate rotating arm 2227, and the clamping plate rotating arm 2227 passes through the upper ring fixing plate 2212 and is arranged on the side of the upper ring clamping unit 224, and a rotating arm base 2228 is arranged on the upper ring fixing plate 2212, and the clamping plate rotating arm 2227 is hinged to the upper ring fixing plate 2212 through a rotating arm pin 2229. On the arm base 2228, the front end of the clamping plate arm 2227 is connected to the clamping plate body 2221, and the rear end is hinged to the output end of the clamping plate driving member 2222. When the clamping plate body 2221 rotates, the hinge point position of the clamping plate arm 2227 and the clamping plate driving member 2222 will change. Therefore, the rear end of the clamping plate driving member 2222 is hinged to the upper circle fixed plate 2212 through the clamping plate base 2226. In this way, the free rotation of the clamping plate body 2221 can be achieved without mutual interference.

[0059] Furthermore, the number of the clamping plate driving member 2222, the clamping plate base 2226 and the clamping plate rotating arm 2227 are all set to two, which are respectively arranged at the upper and lower ends of the upper circle fixing plate 2212, and are connected to the same clamping plate body 2221, driving the upper and lower ends of the clamping plate body 2221 to move simultaneously, which can improve its stability during rotation and will not tilt to one side.

[0060] like Figure 1 As shown, the upper ring clamping mechanism 22 also includes a fixed plate driving unit 223, which at least has: a fixed plate driving member 2231, which is arranged on the processing base 1 through a fixed plate driving seat 2232; and a fixed plate driving rod 2233, which is arranged at the output end of the fixed plate driving member 2231, and is used to drive the upper ring fixing unit 221 to move.

[0061] Specifically, when aligning the liner upper ring 100 and the liner lower ring 200, it is necessary to move the upper ring clamping mechanism 22 toward the lower ring clamping mechanism 21, so a rotational movement method is designed. Specifically, the fixed plate driving seat 2232 is arranged on the processing base 1, and the fixed plate driving member 2231 is hinged on the fixed plate driving seat 2232. The fixed plate driving rod 2233 is controlled by the fixed plate driving member 2231 to extend and retract to realize the pulling or pushing out of the upper ring clamping device. In order to make the upper ring clamping unit 1 224 and the upper ring clamping unit 2 225 rotate synchronously, a fixed plate driving rod 2233 is provided at the end side. Transmission rod 2271, transmission rod 2271 is connected to upper circle clamping unit 1 224 and upper circle clamping unit 2 225 respectively through transmission seat 1 2272 and transmission seat 2 2273, transmission seat 1 2272 and transmission seat 2 2273 are respectively arranged in the middle of upper circle clamping unit 1 224 and upper circle clamping unit 2 225, so that the force is more balanced when transmission rod 2271 pushes them to flip, in addition, when upper circle clamping unit 1 224 and upper circle clamping unit 2 225 move left and right, transmission rod 2271 can move left and right in transmission seat 2 2273, so transmission rod 2271 also has a guiding function.
