[0004] Subsequently, a plurality of circular grooves are turned on the side wall of the main plate away from the shaft seat, an eccentric hole is processed in the shaft seat, and a plurality of screw holes are processed on the circular groove of the main plate.

[0005] When the butterfly plate is processed by heat treatment for the first time, the butterfly plate needs to be hoisted in an electric resistance furnace for heating. Since the eccentric hole has not been processed in the shaft seat, the butterfly plate cannot be hoisted by a lifting hook, and a fixing clamp needs to be used to hoist the butterfly plate.

The lifting piece 31 drives the furnace cover 2 to move up and down through the lifting frame 32, so that the furnace body 1 can be opened and closed.

[0040] Referring to Figure 3 and Figure 4Coaxially rotatable mounting has a rotating disc 10 in the furnace cover 2, the bottom wall of the rotating disc 10 is fixedly installed along the diameter direction of itself and has a crossbar 4. The top wall of the furnace cover 2 is fixedly installed through a support and has a driving member 11, in the application, the driving member 11 can be selected as a servo motor. The bottom end of the driving shaft of the driving member 11 is fixedly installed and has a driving gear 12, the middle of the top wall of the rotating disc 10 is fixedly installed and has a driven gear 32, the driving gear 12 is engaged with the driven gear 32. The driving member 11 can drive the crossbar 4 to rotate through the driving gear 12, the driven gear 32 and the rotating disc 10.

[0041] With reference to Figure 4 , Figure 5 and Figure 6 , the bottom wall of the crossbar 4 is symmetrically provided with two sliding grooves 5 along the length direction of itself, the crossbar 4 is slidingly installed with a sliding block 6 in each sliding groove 5 along the length direction of itself, and the cross section of the sliding block 6 is T-shaped. The crossbar 4 is installed with an elastic member 7 on the side of each sliding groove 5 close to each other, and the ends of the two elastic members 7 away from each other abut against the side walls of the two sliding blocks 6 close to each other. In the application, the elastic member 7 can be selected as a high-temperature-resistant spring. The two elastic members 7 can push the two sliding blocks 6 to move in the two sliding grooves 5 away from each other.

[0042] Each sliding block 6 is installed with two connecting plates 8, and each two connecting plates 8 are fixedly connected through a connecting block 31. The bottom of the four connecting plates 8 is installed with a fixing clamp 9 for clamping and fixing the butterfly plate. The fixing clamp 9 comprises a supporting wheel 91, two clamping wheels 92, arc-shaped plates 93, a first stop wheel 94 and four second stop wheels 95. The supporting wheel 91 is rotatably installed between the two first stop wheels 94 through an axis, and the ends of the two arc-shaped plates 93 close to each other are rotatably installed on the axis of the supporting wheel 91. The diameter of the first stop wheel 94 is greater than that of the supporting wheel 91.

[0043] Each clamping wheel 92 is rotatably installed between the two second stop wheels 95 through an axis, and the ends of the two arc-shaped plates 93 away from each other are rotatably installed on the axes of the two clamping wheels 92. The diameter of the second stop wheel 95 is greater than that of the clamping wheel 92. The two connecting plates 8 on one sliding block 6 are rotatably connected with the two ends of the axis of one clamping wheel 92.

[0044] In the heat treatment process of the butterfly plate, the fixed clamp 9 is used to fix the butterfly plate. First, the butterfly plate is placed between the two arc-shaped plates 93, and the main plate 27 of the butterfly plate falls on the supporting wheel 91. With the help of the gravity of the butterfly plate, the supporting wheel 91 immediately sinks, and the supporting wheel 91 drives the two arc-shaped plates 93 to move downward. Under the linkage action of the connecting plate 8, the two arc-shaped plates 93 are synchronized to move towards the middle, and the arc-shaped plate 93 drives the clamping wheel 92 to precisely fit the outer side wall of the main plate 27. The two clamping wheels 92 and the supporting wheel 91 are equidistantly arranged along the circumference of the main plate 27, thereby forming stable clamping. At the same time, the two first stop wheels 94 and the four second stop wheels 95 on both sides of the main plate 27 are cooperated to complete the all-around limiting of the butterfly plate, and the quick hoisting and fixing are realized. The connecting plate 8 drives the sliding block 6 to move in the sliding groove 5, and the two sliding blocks 6 move towards each other and press the two elastic members 7, so that the two elastic members 7 are contracted and deformed to store elastic potential energy.

[0045] When the heat treatment process is started, the lifting mechanism 3 drives the furnace cover 2 to slowly descend, and the butterfly plate is stably entered into the furnace body 1. During the heat treatment process, the driving member 11 drives the rotating disc 10 to rotate through the driving gear 12 and the driven gear 32, the rotating disc 10 drives the cross rod 4 to rotate, the cross rod 4 drives the fixed clamp 9 to rotate through the sliding block 6 and the connecting plate 8, and the fixed clamp 9 drives the butterfly plate to slowly rotate with the vertical direction as the rotating shaft, so that the butterfly plate is heated more uniformly. After the heat treatment process is completed, the butterfly plate is lifted upward through the clamping tool, at this time, the two elastic members 7 release the elastic potential energy and push the two sliding blocks 6 to slide reversely, and through the connecting plate 8, the two arc-shaped plates 93 are reversely rotated, the arc-shaped plate 93 drives the clamping wheel 92 to separate from the main plate 27, and the butterfly plate is automatically released.

[0046] The fixed clamp 9 is used to clamp and fix the butterfly plate, which not only realizes the full-automatic operation of the butterfly plate fixing and releasing, greatly improves the hoisting efficiency, and effectively reduces the contact area between the fixed clamp 9 and the main plate 27 through the combination fixing mode of the supporting wheel 91, the two clamping wheels 92, the two first stop wheels 94 and the four second stop wheels 95, so as to ensure that the main plate 27 is uniformly heated during the heat treatment process, and the processing quality of the butterfly plate heat treatment is significantly improved.

[0047] The first rotating shaft 13 is rotatably installed in the cross rod 4 along the length direction of the cross rod 4, the first rotating shaft 13 penetrates through the two elastic members 7, and the two ends of the first rotating shaft 13 penetrate through the cross rod 4. The two ends of the first rotating shaft 13 are fixedly installed with the driving bevel gears 14, and the bottom wall of the furnace cover 2 is coaxially fixedly installed with the bevel gear 15, and the two driving bevel gears 14 are engaged with the bevel gear 15.

[0048] Two second rotating shafts 16 are rotatably installed in the crossbar 4, and the two second rotating shafts 16 are in driving connection with the first rotating shaft 13 through a bevel gear set 30. The bevel gear set 30 is composed of two bevel gears 30, and the two bevel gears are installed on the first rotating shaft 13 and the second rotating shaft 16 respectively and are in meshing engagement with each other. The two ends of the two second rotating shafts 16 extend to the two sides of the crossbar 4 in the width direction, and the opposite ends of the two second rotating shafts 16 are fixedly installed with first gears 17.

[0049] A third rotating shaft 18 is rotatably installed in each slider 6, and the two ends of the third rotating shaft 18 extend to the two sides of the slider 6 in the horizontal direction. The opposite ends of the two third rotating shafts 18 are fixedly installed with second gears 19. The two ends of each connecting plate 8 are rotatably sleeved on the ends of the third rotating shaft 18 and the rotating shaft of the clamping wheel 92, and the same end of each third rotating shaft 18 and the clamping wheel 92 is in meshing sleeving with a transmission chain 26.

[0050] When the butterfly plate is placed in the fixed clamp 9, the connecting plate 8 pulls the two sliders 6 to move in the sliding groove 5, the two sliders 6 drive the second gears 19 to move towards each other, so as to make the first gears 17 mesh with the second gears 19. During the rotation of the butterfly plate driven by the rotating disc 10 through the crossbar 4, the crossbar 4 drives the two driving bevel gears 14 to rotate on the bevel gear ring 15 through the first rotating shaft 13, and the bevel gear ring 15 drives the first rotating shaft 13 to rotate through the driving bevel gear 14. The first rotating shaft 13 drives the two second rotating shafts 16 to rotate through the transmission of the bevel gear set 30, and the second rotating shaft 16 in turn drives the first gear 17 to rotate. The first gear 17 cooperates with the second gear 19 to drive the third rotating shaft 18 to rotate, and the third rotating shaft 18 drives the clamping wheel 92 to rotate through the transmission chain 26. The rotation of the clamping wheel 92 drives the main plate 27 of the butterfly plate to rotate in the fixed clamp 9 with the horizontal direction as the rotation axis, so that the butterfly plate can be heated in all directions during the heat treatment process, which significantly improves the heating uniformity and guarantees the effect of heat treatment processing.

[0051] The arc-shaped plate 93 includes first arc plate bodies 931 and second arc plate bodies 932. The opposite ends of the two first arc plate bodies 931 are rotatably installed on the rotating shaft of the supporting wheel 91, and the second arc plate body 932 is slidably installed in the end of the first arc plate body 931 away from the first baffle. The end of the second arc plate body 932 away from the first arc plate body 931 is rotatably installed on the rotating shaft of the clamping wheel 92. A first bolt 20 is slidably installed in the first arc plate body 931, and a plurality of first insertion grooves 21 are equidistantly formed in the second arc plate body 932 along the arc direction of the second arc plate body 932. The first bolt 20 is threadedly installed in the first insertion groove 21, so as to fix the second arc plate body 932 and the first arc plate body 931.

[0052] The fixed clamp 9 has flexible adjustment function for butterfly plates of different sizes. By sliding the second arc plate body 932 inside the first arc plate body 931, the overall length of the arc plate 93 can be conveniently adjusted. When the fixed clamp 9 clamps and fixes butterfly plates of different sizes, one supporting wheel 91 and two clamping wheels 92 can always be uniformly distributed along the circumferential direction of the butterfly plate main plate 27, thereby ensuring the stability and reliability of the fixing effect of the fixed clamp 9. After the arc plate 93 is adjusted to the appropriate length, the first plug 20 is only inserted into the first plug slot 21, and the fixing of the second arc plate body 932 can be quickly completed, which is simple and efficient and effectively improves the adaptation ability of the fixed clamp 9 to butterfly plates of different sizes.

[0053] The supporting wheel 91 is fixedly installed on the rotating shaft, and the mounting rod 22 is fixedly installed on the supporting wheel 91. The counterweight 23 is slidably installed on the mounting rod 22. When the butterfly plate is placed in the fixed clamp 9, the counterweight 23 is located on the side of the main plate 27 away from the shaft seat 28. The second plug 24 is slidably installed in the counterweight 23, and a plurality of second plug slots 25 are formed in the side wall of the mounting rod 22 along the length direction of the mounting rod 22, and the second plug 24 is threadedly installed in the second plug slot 25.

[0054] When the butterfly plate is installed in the fixed clamp 9, the counterweight 23 balances the shaft seat 28 and the reinforcing ribs 29 on the main plate 27, effectively enhancing the installation stability of the butterfly plate in the fixed clamp 9, and making the rotation of the butterfly plate in two directions more stable. In the face of butterfly plates of different sizes, the fixed clamp 9 shows flexible adaptability. The operator can slide the counterweight 23 on the mounting rod 22, accurately adjust the position of the counterweight 23 according to the principle of lever, so that the counterweight 23 can balance the butterfly plates of different specifications and weights. After the counterweight 23 is adjusted to the appropriate position, the second plug 24 is inserted into the second plug slot 25, and the counterweight 23 can be quickly locked, completing the entire balancing and fixing process, and ensuring that various butterfly plates can remain in a stable state in the fixed clamp 9.

[0055] The implementation principle of the embodiment of the application is that the fixed clamp 9 is used to fix the butterfly plate in the heat treatment process of the butterfly plate. First, the butterfly plate is placed between the two arc plates 93, and the main plate 27 of the butterfly plate falls on the supporting wheel 91. With the gravity of the butterfly plate, the supporting wheel 91 immediately sinks, and the two arc plates 93 are driven to move downward. Under the linkage action of the connecting plate 8, the two arc plates 93 on both sides are simultaneously moved towards the middle, and the arc plate 93 drives the clamping wheel 92 to accurately fit the outer side wall of the main plate 27, forming stable clamping. At the same time, the two first stop wheels 94 and the four second stop wheels 95 on both sides of the main plate 27 cooperate to complete the all-around limiting of the butterfly plate, realizing quick hoisting and fixing. The connecting plate 8 drives the sliding block 6 to move in the sliding groove 5, and the two sliding blocks 6 move towards each other and press the two elastic members 7, and the two elastic members 7 shrink and store elastic potential energy.

[0056] When the heat treatment process starts, the lifting mechanism 3 drives the furnace cover 2 to slowly descend, and the butterfly plate is stably brought into the furnace body 1. During the heat treatment process, the driving part 11 drives the rotating disc 10 to rotate through the driving gear 12, the rotating disc 10 drives the cross rod 4 to rotate, the cross rod 4 drives the fixed clamp 9 to rotate through the sliding block 6 and the connecting plate 8, and the fixed clamp 9 drives the butterfly plate to slowly rotate, so that the butterfly plate is heated more uniformly. After the heat treatment process is completed, the butterfly plate is lifted upward through the clamping tool, at this time, the two elastic parts 7 release the elastic potential energy and push the two sliding blocks 6 to slide reversely, which is conducted through the connecting plate 8, so as to promote the two arc-shaped plates 93 to rotate reversely, the arc-shaped plates 93 drive the clamping wheels 92 to be separated from the main plate 27, and the butterfly plate is automatically released.
