Then the external winding device works to wind the steel cable 21, and the steel cable 21 drives the horizontal plate 60 to move from left to right along the direction of the steel cable 21. The clamped bucket is moved to the working area 3 and heat treated. At the same time, the bucket that needs to be heat treated continues to be clamped and placed in the placement area 4. After the bucket that has completed the heat treatment is transferred to the unloading area 5 and taken out, the bucket that has not completed the heat treatment continues to move to the working area 3 for heat treatment. The above operation is repeated and the buckets are batch-heat treated.

[0035] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the clamping mechanism 7 includes a fixed plate 70, and a fixed plate 70 parallel to the side plate 1 is fixedly provided on the lower end surface of the middle position of the horizontal plate 60. Two left-right symmetrical rotating shafts 71 are rotatably provided on the fixed plate 70. The parts of the rotating shaft 71 located on the front and rear sides of the fixed plate 70 are each provided with two movable plates 72 distributed front and back. The opposite surfaces of the two movable plates 72 on the same rotating shaft 71 and located on the same side of the fixed plate 70 are both fixed with a through column 73. The horizontal plate 60 is provided with a driving group 74 for driving the four through columns 73 located on the same side of the fixed plate 70 to clamp and fix the bucket.

[0036] like Figure 3 、 Figure 6 and Figure 7As shown, the driving group 1 74 includes a thread groove 740, and two groups of front-to-back symmetrical groove groups are provided on the rotating shaft 71, and one group of groove groups corresponds to the two movable plates 72 located on the same side of the fixed plate 70. The groove group includes two front-to-back symmetrical thread grooves 740, and the thread grooves 740 and the movable plates 72 are threadedly matched. The movable plates 72 and the horizontal plate 60 are slidably connected. The lower end surface of the horizontal plate 60 is fixedly provided with two front-to-back symmetrical rectangular plates 741, and the rotating shaft 71 passes through the rectangular plate 741. The front end surface of the front rectangular plate 741 is rotatably provided with a driving shaft 742. The rotating shaft 71 and the driving shaft 74 located in front of the front rectangular plate 741 2 are all fixedly provided with sprockets 743, and the three sprockets 743 are connected and transmitted by chains. A driving gear 744 is fixedly provided on the driving shaft 742 and is located in front of the sprocket 743. Rectangular bars 745 are fixedly provided on both end surfaces of the front side plate 1, and the rectangular bar 745 on the left is shorter than the rectangular bar 745 on the right. A Z-shaped plate 746 is fixedly provided on the rear end surface of the rectangular bar 745. A rack plate 747 meshing with the driving gear 744 is fixedly provided on the rear end surface of the Z-shaped plate 746, and the rack plate 747 on the left is located above the corresponding driving gear 744, and the rack plate 747 on the right is located below the corresponding driving gear 744.

[0037] like Figure 4 、 Figure 5 and Figure 6 As shown, the front end face of the front rectangular plate 741 is provided with a locking group 75, and the locking group 75 includes a fixed column 750, and the front end face of the front rectangular plate 741 is fixedly provided with a fixed column 750 located below the drive shaft 742, and a sliding plate 751 is movably provided on the fixed column 750, and a spring 752 mounted on the fixed column 750 is fixedly provided between the sliding plate 751 and the rectangular plate 741, and a locking column 753 is fixedly provided on the rear end face of the sliding plate 751, and a plurality of circumferentially evenly distributed limiting holes 754 are opened on the front end face of the driving gear 744 and cooperate with the locking column 753, and a release group 76 is provided on the rectangular bar 745.

[0038] like Figure 4 and Figure 5 As shown, the release group 76 includes a connecting bar 760, and the rear end face of the rectangular bar 745 is fixedly provided with a connecting bar 760 located below the corresponding Z-shaped plate 746, and the rear end face of the connecting bar 760 is fixedly provided with a guide member 761, which is composed of an inclined section on the left and a horizontal section on the right, and the left end portion of the inclined section on the left is inclined toward the direction of the driving gear 744.

[0039] When working, in the initial state, the locking column 753 is located in the limit hole 754. When the external winding device works to wind the steel cable 21, the steel cable 21 drives the horizontal plate 60 to move to the placement area 4 through the connecting block 6. During the movement of the horizontal plate 60, the sliding plate 751 cooperates with the guide member 761 on the left. During the movement of the sliding plate 60 to the right, the inclined section of the guide member 761 contacts the sliding plate 751, and the sliding plate 751 continues to move forward. When the sliding plate 751 and the inclined section of the guide member 761 contact each other, the driving gear 744 is not The tooth structure on the rack plate 747 contacts and engages with each other. When the sliding plate 751 moves to contact the horizontal section of the guide member 761, the sliding plate 751 drives the locking column 753 to exit the corresponding limit hole 754, and the locking column 753 releases the lock on the drive gear 744, and the spring 1 752 is stretched. At this time, the two buckets are placed in a front and back distribution state under the horizontal plate 60, and the through holes on the two hinge plates on the buckets are respectively located between the two through columns 73. The two hinge plates set on the buckets are existing technology and are not marked.

[0040] As the sliding plate 751 contacts the horizontal section of the guide member 761 and continues to move to the right, the horizontal plate 60 drives the rectangular plate 741 and the driving gear 744 thereon to move synchronously, and the driving gear 744 is meshed with the rack plate 747 on the left side. Therefore, the driving gear 744 rotates forward during the right movement, and the driving gear 744 drives the driving shaft 742 to rotate synchronously, and the driving shaft 742 drives the sprocket 743 thereon to rotate. Through the connection transmission between the corresponding three sprockets 743 and the chain, the sprocket 743 drives the corresponding rotating shaft 71 to rotate synchronously, and the screw on the rotating shaft 71 is used to rotate. The cooperation between the groove 740 and the corresponding movable plate 72 enables the movable plate 72 to move along the axial direction of the rotating shaft 71, that is, the two movable plates 72 on the same side of the fixed plate 70 in the front-to-back direction and located on the same rotating shaft 71 approach each other, and the movable plate 72 drives the through-columns 73 thereon to move synchronously, and the through-columns 73 move through the through-holes at the corresponding positions on the hinge plate. The four through-columns 73 on the same side of the fixed plate 70 cooperate with each other to initially clamp the buckets, and then the steel cable 21 can drive the two buckets clamped thereunder to move to the heat treatment area for heat treatment operations through the horizontal plate 60. It should be noted that in order to improve the convenience of the through-columns 73 passing through the through-holes at the corresponding positions on the hinge plate, the existing conveying equipment can be used to drive the buckets to move synchronously and at a constant speed during the rightward movement of the horizontal plate 60 to ensure that the relative positions of the buckets and the through-columns 73 remain unchanged.

[0041] When the sliding plate 751 continues to move to the right and breaks away from the contact with the guide member 761, the sliding plate 751 moves backward through the spring 1 752, and the sliding plate 751 drives the locking column 753 thereon to be clamped into the limiting hole 754. The locking column 753 cooperates with the corresponding limiting hole 754, and the driving gear 744 and the driving shaft 742 are limited and fixed, that is, the two rotating shafts 71 are limited and fixed, so that in the process of the bucket moving from the placement area 4 through the working area 3 to the unloading area 5, the moving plate 72 and the through column 73 are always restricted, that is, the placed bucket is restricted on the through column 73, which is convenient for subsequent heat treatment operations.

[0042] When the bucket moves from the working area 3 to the unloading area 5, the steel cable 21 drives the sliding plate 751 to move synchronously through the horizontal plate 60. The above operation is repeated through the cooperation between the sliding plate 751 and the guide member 761 and the rack plate 747 on the right side. The driving gear 744 is reversed through the cooperation between the right rack plate 747 and the driving gear 744, so that the corresponding two moving plates 72 move away from each other, that is, the two moving plates 72 on the same side of the fixed plate 70 in the front and rear direction and located on the same rotating shaft 71 drive the corresponding through column 73 to exit the through hole of the hinge plate on the bucket, so as to remove the heat-treated bucket.

[0043] By setting up a steel cable 21 to drive the clamped bucket to move to the working area 3 for heat treatment operations, it is convenient to carry out batch heat treatment operations on the bucket, reduce manual participation, and facilitate operation, thereby reducing production costs. The bucket first rises in the working area 3, then moves to the right, and then descends, extending the moving path. In this way, the time for the bucket to perform heat treatment operations in a limited space is increased, thereby improving space utilization.

[0044] like Figure 8 and Figure 9 As shown, the through column 73 is a circular tubular structure, and a plurality of circumferentially evenly distributed slider grooves are provided on the circumferential surface of the through column 73. A sliding bar 77 is slidably provided in the sliding block groove, and an arc-shaped expansion plate 770 is fixedly provided on the end surface of the sliding bar 77 away from the through column 73. A driving group 78 for driving the expansion plate 770 to expand is provided on the through column 73.

[0045] like Figure 8 and Figure 9As shown, the driving group 2 78 includes a guide member 780, and a truncated cone-shaped guide member 780 is slidingly provided in the through column 73, and the diameter of the end of the guide member 780 facing the adjacent movable plate 72 is smaller than the diameter of the end away from the adjacent movable plate 72, and the end face of the sliding bar 77 close to the guide member 780 is fixedly provided with an arc-shaped matching plate 781 that cooperates with the guide member 780, and the end face of the guide member 780 facing the adjacent movable plate 72 is fixedly provided with a driving column 782, and the end face of the driving column 782 away from the corresponding guide member 780 is fixedly provided with a force plate 783, and the end face of the fixed plate 70 and the rectangular plate 741 facing the adjacent movable plate 72 are fixedly provided with L-shaped plates 784 corresponding to the adjacent movable plates 72, and the vertical section of the L-shaped plate 784 cooperates with the corresponding force plate 783.

[0046] like Figure 8 and Figure 10 As shown, a mounting plate 79 located between the corresponding L-shaped plate 784 and the guide member 780 is fixedly provided on the inner wall of the through column 73, and the corresponding driving column 782 passes through the mounting plate 79, and a movable plate 790 located between the mounting plate 79 and the corresponding force-bearing plate 783 is fixedly provided on the driving column 782, and a spring 2 791 mounted on the corresponding driving column 782 is fixedly provided between the movable plate 790 and the mounting plate 79.

[0047] When the movable plate 72 drives the through-column 73 thereon to pass through the through-hole on the corresponding hinge plate, the movable plate 72 drives the guide member 780, the driving column 782 and the force plate 783 therein to move synchronously through the through-column 73, and then the force plate 783 contacts the corresponding L-shaped plate 784. The vertical section of the L-shaped plate 784 has a restrictive effect on the force plate 783. The movable plate 72 drives the through-column 73 to continue to move, while the driving column 782, the guide member 780 and the force plate 783 stop moving. The spring 2 791 is stretched, and the through-column 73 drives all the matching plates 781, the sliding bar 77 It moves synchronously with the support plate 770, and the cooperation between the guide 780 and the matching plate 781 enables the matching plate 781 to drive the corresponding support plate 770 away from the through-column 73 through the sliding plate 751. Therefore, the multiple support plates 770 on the same through-column 73 cooperate with each other to provide internal support for the through holes on the corresponding hinge plates. By clamping and internally supporting the through holes on the two hinge plates on the same bucket, the bucket is clamped and fixed. The four-point fixation improves the stability of the bucket during movement, avoiding the problem of the bucket shaking and causing it to fall off or affecting the heat treatment operation.

[0048] When the bucket has been heat-treated and is in the process of unloading in the unloading area 5, the movable plate 72 drives the through column 73 to move and reset through the cooperation between the sliding plate 751 and the guide member 761 on the right side and the cooperation between the driving gear 744 and the rack plate 747 on the right side. The through column 73 exits the hinge plate, and the elastic force generated by the spring 2 791 through its own deformation makes the force plate 783 and the L-shaped plate 784 close to each other. When the through column 73 drives the mounting plate 79 to move synchronously, the distance between the mounting plate 79 and the movable plate 790 becomes smaller, that is, the deformation amplitude of the spring 2 791 becomes smaller, and the spring 2 791 is initially reset. As the movable plate 72 continues to move, the force plate 783 is separated from the L-shaped plate 784, and the through column 73 drives the guide member 780 and the force plate 783 to reset.
