[0052] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0053] Please refer to Figure 1-Figure 16 The present invention provides a thin-walled stationary blade ring machining auxiliary equipment and a method of use, and the specific scheme is as follows:

[0054] A thin-walled stationary blade ring machining auxiliary equipment comprises a main body mechanism 1, a connection adjustment mechanism 3, a force balancing mechanism 2, a lifting load adjustment mechanism 4 and other components.

[0055] The main body mechanism 1 includes a protective clamping device 11, a bottom plate 111 is provided at the lower end of the protective clamping device 11, the upper end surface of the bottom plate 111 is provided with a protective material, and a top plate 112 is provided at the upper end, the top plate 112 is connected with a clamping device 12 and a first lifting ear 13, the first lifting ear 13 is located in the middle position of the top plate 112 and is fixedly connected to the top plate 112, the first lifting ear 13 is connected to the force balancing mechanism 2 through a rope, the clamping device 12 is preferably two arranged on both sides of the first lifting ear 13, the lower end of the clamping device 12 is connected to a protective block 121, the two can rotate with each other, and no relative displacement occurs between the protective block 121 and the workpiece 5 during the downward pressing process of the clamping device 12 , effectively protecting the processing surface of the workpiece 5, the lower surface of the workpiece 5 contacts the bottom plate 111, and the upper surface contacts the protective block 121, which can effectively protect the processing surface of the workpiece 5 from being damaged. A telescopic handle 122 is arranged on the upper end of the clamping device 12, and the telescopic handle 122 drives the lifting and lowering of the clamping device 12, which is convenient for the operator to tighten and loosen, and can clamp the workpiece 5 with a thickness between 20mm-100mm, with a wide range of adaptability and strong versatility. A slider 141 is installed on the lower surface of the bottom plate 111, and the slider 141 is slidably arranged on the first slide rail 14, and the first slide rail 14 is installed on the base 16 of the main mechanism 1, and the base 16 is installed at one end of the profile support rod 17 Baffles 142 are provided at both ends of the first slide rail 14 to prevent the slider 141 from derailing. The upper surface of the baffle 142 is lower than the upper surface of the slider 141 to prevent the baffle 142 from interfering with the bottom plate 111. The protective clamping device 11 can be adjusted forward and backward within a range of 0-300 mm. An adjustment mechanism 15 is provided to control the movement of the first slide rail 14. The adjustment mechanism 15 includes an adjustment handle 151, a lead screw 152, an abutment plate 153, and a lead screw support seat 154; the lead screw support seat 154 is fixed on the profile support rod 17, and the lead screw support seat 154 supports the lead screw 152. A thread is provided at the position in contact with the lead screw 152, and the thread cooperates with the lead screw 152. The lead screw 152 is threadedly connected to the abutment plate 153, and the abutment plate 153 is welded to the rear end of the protective clamping device 11. The lead screw support seat 154 is movably connected to the profile support rod 17. The adjustment handle 151 adjusts the length of the lead screw 152. The lead screw 152 drives the protective clamping device 11 to slide back and forth. After sliding to a suitable position, the protective clamping device 11 clamps the workpiece 5. The lead screw 152 has a self-locking function, which prevents the slider 141 from sliding during lifting. The adjustment handle 151 can be replaced by a cylinder, a motor, etc. to control the movement of the slider 141 on the first slide rail 14. Each protective clamping device 11 can be moved individually, so it can meet the lifting requirements of the workpiece 5.

[0056] The protective clamping device 11 can also be removed from the main body 1 and used separately, expanding the scope of use. From the original function of only being able to lift inner holes, it can now be used to lift square plate products. The protective clamping device 11 can also be reversed to be able to lift outer circles. It has a wide range of applications, good versatility, and is more convenient to use.

[0057] The force balancing mechanism 2 includes a supporting device 21, which is the main body of the mechanism and is composed of welded alloy steel plates, with sufficient rigidity and heavy load-bearing capacity. The supporting device 21 is provided with an intermediate lifting ear 23, and preferably four supporting legs 211 are provided. The supporting legs 211 are provided with adjusting slots 22. The adjusting slots 22 to the lower end of the supporting legs 211 are hollow structures, and the adjusting slots 22 are inclined near the intermediate lifting ear 23. The adjusting slots 22 are provided with a plurality of semicircular slots 221, and there are spacings between the semicircular slots 221. A partition is provided in the middle of the spacings between two adjacent semicircular slots 221 to prevent the adjusting slots 22 from deforming and increase the load-bearing capacity of the adjusting slots 22. One end of the semicircular slot 221 near the intermediate lifting ear 23 is higher than the horizontal position of the center of the semicircular slot 221. The end away from the middle hanging ear 23 is lower than the horizontal position of the center of the semicircular groove 221. The force balancing mechanism 2 also includes a pin 25, which is installed on the semicircular groove 221. A rope is slidably arranged in the middle of the pin 25. The pin 25 is symmetrically installed with a rotating sleeve 24 at both ends of the rope. The rotating sleeve 24 is clamped on both sides of the semicircular groove 221. A protrusion is arranged at one end of the pin 25, and a cotter pin 26 is installed at the other end to prevent the pin 25 from falling off during use, which can ensure that the position of the rotating sleeve 24 and the pin 25 is more convenient to replace. The rotating sleeve 24 and the pin 25 move toward the middle hanging ear 23 under the action of gravity, and the groove edge of the semicircular groove 221 near one end of the middle hanging ear 23 is higher than the radius, which can just clamp the rotating sleeve 24 and make it more stable. There is a clearance fit between the rotating sleeve 24 and the pin 25. During the installation and use of the rope, the rotation of the pin 25 can be driven to effectively protect the rope from damage. The material of the rotating sleeve 24 is lower in hardness than the supporting leg 211 and the pin 25, and other parts can be effectively protected from damage during use. When the rotating sleeve 24 is damaged, only the rotating sleeve 24 needs to be replaced, thereby reducing the maintenance cost of the sling. The reason why the force balancing mechanism 2 can play the role of balancing force is that during the lifting process, the force of the hook can be effectively and evenly dispersed to the supporting leg 211, and the pin 25 is located directly above the first lifting ear 13, so as to ensure that when the workpiece 5 is lifted, all the forces at each lifting position of the workpiece 5 are vertically upward, and no force squeezing toward the center of the circle is generated, thereby ensuring the stability of the lifting and clamping of the workpiece 5 and preventing the workpiece 5 from being deformed; when lifting the workpiece 5, the position of the rotating sleeve 24 and the pin 25 can be moved to ensure that the pin 25 is located directly above the first lifting ear 13, thereby ensuring that the rope is in a vertical state, ensuring that the force acting on the workpiece 5 at each lifting point is balanced, and ensuring that no deformation occurs during the lifting process.

[0058] The other end of the profile support rod 17 is connected to a connection adjustment mechanism 3, which includes a telescopic positioning sleeve 31 and an internal support frame 32. The telescopic positioning sleeve 31 is fixedly connected to the internal support frame 32. Positioning pin holes 34 are provided on the profile support rod 17 and the telescopic positioning sleeve 31. The profile support rod 17 and the telescopic positioning sleeve 31 are clearance-matched to achieve telescopic adjustment. After adjusting to the appropriate position, the position is fixed by the position positioning pin 33. In order to ensure safety and reliability during the lifting process, the position positioning pin 33 is set in the form of a threaded and pin combination. The pin structure at the lower end can effectively ensure the accuracy of positioning, and the threaded structure at the upper end ensures the stability of the pin and prevents the pin from falling off. In order to better meet the needs of products with different diameters, the effective adjustment range of the diameter direction of this part is between 0-1000mm. Combined with the unilateral 0-300mm adjustment range of the main mechanism 1, the total adjustment range in the diameter direction can reach 0-1600mm.

[0059] The lifting load adjustment mechanism 4 includes a sliding nose device 41 and a position adjustment pin 43. The lower end of the sliding nose device 41 is processed with a sliding groove 411, which is slidably matched with the second slide rail 42. The position adjustment pin 43 is set as a step pin. The position adjustment pin 43 is provided with a spring 44, which is locked in the hole of the sliding nose device 41 through a nut 45. Every time the position of the lifting load adjustment mechanism 4 needs to be adjusted, the position adjustment pin 43 is pulled out from the limiting hole 421 to allow the entire mechanism to slide back and forth to adjust the position. After sliding to the appropriate position, the position adjustment pin 43 will automatically insert into the limiting hole 421 on the slide rail surface of the second slide rail 42 under the action of the spring 44. The limiting hole 421 is fastened with the position adjustment pin 43 to facilitate the operator to adjust the position of the sliding nose device 41. When the sliding nose device 41 is located directly above the pin 25, the lifting capacity of the sling reaches the maximum value. On the contrary, when the sliding nose device 41 of the lifting load adjustment mechanism 4 is farther away from the pin 25, the lifting force of the lifting is smaller. If the middle lifting lug 23 is used for lifting, the lifting capacity of the entire lifting device is the smallest; of course, lifting with the middle lifting lug 23 is also the most convenient lifting method. As long as the weight of the workpiece 5 does not exceed 40 tons, it is most convenient to use the middle lifting lug 23 for lifting. Example 1

[0060] The specific working steps of the inner diameter of the lifting workpiece 5 of the present invention are as follows:

[0061] Step 1, adjusting the connection adjustment mechanism 3 to a size that can accommodate the inner diameter of the workpiece 5;

[0062] Step 2, after inserting, adjust the connection adjustment mechanism 3 so that the protective clamping device 11 clamps the workpiece 5, fix the position of the first slide rail 14 where the main body mechanism 1 is located, and then use the telescopic handle 122 to tighten each clamping device 12 to clamp the workpiece 5;

[0063] Step 3, install the rope on the pin 25, the pin 25 is placed at the position of the semicircular groove 221, and the position of the rope and the first lifting ear 13 are vertically corresponding to each other to ensure that the lifting force at each location is consistent;

[0064] Step 4, install the rotating sleeve 24 on the pin 25, and then install the cotter pin 26 to prevent the pin 25 from slipping during use;

[0065] Step 5: If the weight of the workpiece 5 exceeds 40 tons, the lifting load adjustment mechanism 4 needs to be activated. When the lifting load adjustment mechanism 4 is activated, the position of the sliding nose device 41 needs to be adjusted to align with the pin 25. If the lifting load adjustment mechanism 4 is not used, the middle lifting lug 23 is directly lifted;

[0066] Step 6, use the crane to prepare for lifting;

[0067] Step 7, the workpiece 5 is placed at the processing location, the clamping device 12 is loosened using the telescopic handle 122, the connection adjustment mechanism 3 is adjusted so that the main mechanism 1 can withdraw the workpiece 5, and the workpiece 5 is placed at the auxiliary tool storage location to complete the overall process. Example 2

[0068] The specific working steps of the outer diameter of the hoisting workpiece 5 of the present invention are as follows:

[0069] Step 1, the protective clamping device 11 is reversed to clamp the workpiece 5, and then the telescopic handle 122 is used to tighten each clamping device 12 to clamp the upper and lower surfaces of the workpiece 5 to ensure that the workpiece 5 will not loosen and fall;

[0070] Step 2: Install the first slide rail 14 and connect the adjustment mechanism 3, and connect the adjustment mechanism 3 to support the workpiece 5.

[0071] Step 3, install the rope on the pin 25, the pin 25 is placed at the position of the semicircular groove 221, and the position of the rope and the first lifting ear 13 are vertically corresponding to each other to ensure that the lifting force at each location is consistent;

[0072] Step 4, install the rotating sleeve 24 on the pin 25, and then install the cotter pin 26 to prevent the pin 25 from slipping during use;

[0073] Step 5: If the weight of the workpiece 5 exceeds 40 tons, the lifting load adjustment mechanism 4 needs to be activated. The lifting load adjustment mechanism 4 is activated to adjust the position of the sliding nose device 41 to align with the pin 25. If the lifting load adjustment mechanism 4 does not need to be activated, the middle lifting lug 23 is directly lifted.

[0074] Step 6, use the crane to prepare for lifting;

[0075] Step 7, the workpiece 5 is placed at the processing location, the clamping device 12 is loosened using the telescopic handle 122, the connection adjustment mechanism 3 is disassembled, and the workpiece 5 is placed at the auxiliary tool storage location to complete the overall process.
