Description

Technical Field

[0001] The present invention relates to the technical field of additive repair, and in particular to a blade workpiece clamping structure for additive repair. Background Art

[0002] Steam turbines are mainly used as prime movers for power generation, and can also directly drive various pumps, fans, compressors and ship propellers. Steam turbine blades are the "heart" of steam turbines and are extremely important parts of steam turbines. Blades are generally in harsh environments such as high temperature, high pressure, high speed or wet steam zone, and are subjected to centrifugal force, steam force, steam excitation force, corrosion and vibration. The manufacturing cost of blades is high. If they can be repaired and remanufactured after failure, a lot of social resources can be saved. At present, the main repair methods include carbide surfacing, carbide inlay, surface chrome plating, electric spark strengthening treatment, surface oxidation, surface heat treatment and laser cladding. Laser cladding has the advantages of high precision and good performance, and is widely used in blade repair. However, traditional laser cladding technology is prone to problems such as cracks and pores. The use of magnetic field and electric field to assist the laser cladding process at the same time can effectively regulate the movement of molten pool fluid, internal particle distribution and cladding defects during laser remanufacturing, play a significant shape control effect, effectively reduce defects such as pores, impurities, cracks, and obtain excellent performance.

[0003] For example, the blade clamping device for electromagnetic field composite laser additive repair with publication number CN110791756B ensures the safety and stability of the workbench by using an insulating flange to contact the four-jaw chuck. The device fits tightly with the fork-shaped root of the blade, which can increase the contact area, thereby reducing the contact resistance and reducing heat. The adjustability of the device can clamp turbine blades with fork-shaped roots of different sizes, but in actual use, it can only clamp the root on the blade, and cannot clamp and fix the blade body. It is not suitable for fixing blades without roots. If only the root can be fixed, the root cannot be repaired by additive. If the surface of the root is damaged, it cannot be repaired, and it is fixed by pressing down with a wedge-shaped movable block. If the blade is fixed directly, a certain downward pressure will be generated on the blade, and the blade will generate a certain amount of heat during the repair process. If the blade is thin as a whole, it is easy to produce a certain deformation under pressure during the repair process, which will affect the normal use of the blade. There are certain usage defects.

[0004] Therefore, we propose a blade workpiece clamping structure for additive repair in order to solve the above problems. Summary of the invention

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) The blade workpiece clamping structure for additive repair has a clamping assembly disposed between the movable frame and the base, so that when fixing the blade body, the blade body can be fixed, or the blade root on the blade body can be fixed. The blade body can support the blade body during the repair process to avoid deformation of the blade body, and blade bodies of different shapes can be fixed, thereby improving the scope of application and practicality.

[0029] (2) A clamping assembly is provided between the movable frame and the base. The vertical plate can be mounted on the four-jaw chuck through the connecting seat. When fixing the blade body, the blade body can be placed between the movable frame and the base. The position of the blade body can be adjusted through the supporting assembly. Then, the electric cylinder can be started to drive the movable frame to descend, so that the two sets of rubber rollers at the top and bottom contact the blade body. Then, as the movable frame descends, the rubber rollers can be rotated on the blade body, so that the rotating frame and the rotating rod can rotate. When the rotating rod rotates on the mounting frame, the torsion spring can be deformed, and then the blade body is pressed and fixed by the two sets of rubber rollers. The rotation amplitude of the rotating frame is controlled according to the size of the blade body, so that the two sets of rubber rollers clamp the two sides of the blade body, so that the blade body is only subjected to the clamping force and is not affected by the Excessive pressure can avoid deformation of the blade body. When the upper rotating rod rotates, the steel wire rope can be stretched through the fixed rod to move, and then the movable plate can be pulled to move. After the movable plate moves, it drives the movable rod to slide on the movable frame and compress the reset spring, so that the two rubber plates can fix the two sides of the blade body. When pressure is applied to the two sides of the blade body, the rubber roller can support one side of the rubber plate, and at the same time, the blade body can be prevented from being deformed by the lateral clamping force. When the blade body is fixed, the blade body can be fixed through the clamping assembly, and the blade root on the blade body can also be fixed. The blade body can support the blade body during the repair process to avoid deformation of the blade body, and blade bodies of different shapes can be fixed, which improves the scope of application and practicality.

[0030] (3) When the blade body is clamped, the rubber roller contacts the blade body, and then the rubber roller rotates with the rotation of the rotating frame, thereby driving the first pulley to rotate, and then the second pulley is driven to rotate through the belt, so that the cleaning roller can rotate to wipe the surface of the blade body, and when the cleaning roller rotates along the curved surface of the blade body, the arc rod can slide on the fixed frame, and the telescopic spring can be stretched to make the cleaning roller and the rubber roller rotate as the axis, so that the cleaning roller can always fit the curved surface on the blade body, and then the residual oil or stains on the surface of the blade body can be wiped by the rotation of the cleaning roller, so as to avoid the oil or stains reducing the friction of the rubber roller, and the blade body can be cleaned, which is convenient for subsequent additive repair and improves practicality;

[0031] (4) When fixing the blade body, place the blade body on the two second rollers. The blade body can move on the second rollers to drive the second rollers to rotate, and the left and right positions of the blade body can be adjusted. Then, the U-shaped rod can be pulled to drive the connecting frame and the second rollers to move downward. The movement of the U-shaped rod compresses the compression spring, and then the first roller comes into contact with the blade body, so that the blade body can be moved forward and backward. During the downward movement of the blade body, the sliding rod slides on the base, and the supporting spring can be stretched, so that the front and rear positions of the blade body can be adjusted, so that one side of the blade body is aligned with the clamping assembly, which is convenient for subsequent clamping and fixing to avoid damage to the blade body.

Embodiment 3

[0059] like Figure 1-Figure 2 and Fig. 9As shown, when the blade body 101 is fixed, the blade body 101 is placed on two second rollers 309, and the blade body 101 can move on the second rollers 309 to drive the second rollers 309 to rotate, so as to adjust the left and right position of the blade body 101, and then the U-shaped rod 307 can be pulled to drive the connecting frame 308 and the second rollers 309 to move downward, and the movement of the U-shaped rod 307 causes the compression spring 310 to be compressed, and then the first roller 303 comes into contact with the blade body 101, so that the blade body 101 can be moved forward and backward, and the blade body 101 makes the sliding rod 301 slide on the base 1 during the downward movement, and the support spring 304 can be stretched, so that the front and rear position of the blade body 101 can be adjusted, so that one side of the blade body 101 is aligned with the clamping assembly 2, which is convenient for subsequent clamping and fixing to avoid damage to the blade body 101.

[0060] Working principle: When using the blade workpiece clamping structure for additive repair, first, according to Figure 1-Figure 9 As shown, the vertical plate 102 can be installed on the four-claw chuck through the connecting seat 103. When the blade body 101 is fixed, the blade body 101 can be placed between the movable frame 107 and the base 1. The position of the blade body 101 is adjusted by the support assembly 3, and then the electric cylinder 106 can be started to drive the movable frame 107 to descend, so that the two sets of rubber rollers 204 at the top and bottom contact the blade body 101. Then, as the movable frame 107 descends, the rubber rollers 204 can be rotated on the blade body 101, so that the rotating frame 203 and the rotating rod 202 rotate. When the rotating rod 202 rotates on the mounting frame 201, it can drive the torsion spring 205 to deform, and then the blade body 101 is pressed and fixed by the two sets of rubber rollers 204. The size of the body 101 controls the rotation amplitude of the rotating frame 203, so that the two sets of rubber rollers 204 clamp the two sides of the blade body 101, so that the blade body 101 will only be subjected to the clamping force and will not be subjected to excessive pressure, thereby avoiding deformation of the blade body 101. While the upper rotating rod 202 rotates, the steel wire rope 209 can be stretched by the fixed rod 207 to move, thereby pulling the movable plate 211 to move. After the movable plate 211 moves, it drives the movable rod 210 to slide on the movable frame 107 and compresses the reset spring 213, thereby allowing the two rubber plates 212 to fix the two sides of the blade body 101. When pressure is applied to the two sides of the blade body 101, the rubber roller 204 can support one side of the rubber plate 212, while preventing the blade body 101 from being deformed by the lateral clamping force.

[0061] When the blade body 101 is clamped, the rubber roller 204 contacts the blade body 101, and then as the rotating frame 203 rotates, the rubber roller 204 can be rotated, thereby driving the first pulley 221 to rotate, and then the second pulley 222 is driven by the belt to rotate, so that the cleaning roller 220 can rotate to wipe the surface of the blade body 101, and when the cleaning roller 220 rotates along the curved surface on the blade body 101, the arc rod 216 can slide on the fixed frame 215, and the telescopic spring 217 can be stretched to make the cleaning roller 220 rotate with the rubber roller 204 as the axis, so that the cleaning roller 220 can always fit the curved surface on the blade body 101, and then the residual oil or stains on the surface of the blade body 101 can be wiped by the rotation of the cleaning roller 220, so as to avoid the oil or stains from reducing the friction of the rubber roller 204, and the blade body 1 01 is cleaned to facilitate subsequent additive repair and improve practicality. When fixing the blade body 101, the blade body 101 is placed on the two second rollers 309. The blade body 101 can move on the second rollers 309 to drive the second rollers 309 to rotate, and the left and right positions of the blade body 101 can be adjusted. Then, the U-shaped rod 307 can be pulled to drive the connecting frame 308 and the second roller 309 to move downward. The movement of the U-shaped rod 307 compresses the compression spring 310, and then the first roller 303 contacts the blade body 101, so that the blade body 101 can be moved forward and backward. During the downward movement of the blade body 101, the sliding rod 301 slides on the base 1, and the support spring 304 can be stretched, so that the front and rear positions of the blade body 101 can be adjusted, so that one side of the blade body 101 is aligned with the clamping assembly 2, which is convenient for subsequent clamping and fixing to avoid damage to the blade body 101.
