Description

Technical Field

[0001] The invention relates to the technical field of laser cladding, and in particular to a composite laser high-speed cladding device for shaft parts. Background Art

[0002] The existing laser cladding devices use high-power lasers as heat sources to quickly heat and melt the surface of the part material and ceramic powder or external processing alloy. After solidification, a surface coating can be formed on the surface of the part to improve the wear resistance, corrosion resistance, heat resistance, and oxidation resistance of the part surface.

[0003] A common technical method is to clamp both ends of the part and use a rotating device to drive the part to rotate. At the same time, the laser cladding device moves laterally along the surface of the part to perform comprehensive and efficient cladding on the part. However, in this process, due to the different shapes and sizes of shaft parts, some parts are not cylindrical and will have uneven positions. These positions require frequent adjustment of the position of the laser head to maintain a close distance from the part, otherwise uneven cladding is likely to occur. However, frequent adjustment of the laser head will affect the overall processing efficiency. Summary of the invention

[0014] Furthermore, a second spring is fixed to the outer end of the plug plate, and the other end of the second spring is fixedly connected to the slider.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention drives the second screw to rotate through a motor, and the slider cooperates with the second screw thread to move along the slide frame, and drives the laser head to move horizontally through the plug plate and the mounting seat. In this process, the plug plate slides out along the bottom of the slider under the guidance of the soft strip, so as to keep the distance between the laser head and different positions of the shaft part body close.

[0017] 2. The present invention is located at the entrance end of the limit assembly through the rear plate, at this time, the soft strip is pressed near the side plate by the pressure plates on both sides of the rear plate, and the opening of the limit assembly is maximized. As the front plate clamps the shaft part body to move and dock with the rear plate, the front plate and the rear plate slide synchronously along the slide rail, and the shaft part body is sent into the limit assembly. After part of the soft strip is not restricted by the pressure plate, the insertion rod is inserted along the side plate through the elastic force of the third spring, and the soft strip is attached to the surface of the shaft part body, maintaining the same shape as its concave and convex, until the shaft part body completely enters the limit assembly, and the soft strip is also completely wrapped on both sides of the shaft part body. In this process, in order to ensure that the soft strip can be attached to the surface of the shaft part body, the winding seats at both ends can unwind the soft strip length according to the needs of the soft strip, and the winding seat can be fixed by bolts to prohibit further winding and unwinding, so as to keep the length of the soft strip fixed, thereby facilitating the movement of the laser head.

[0018] 3. The bottom of the laser head of the present invention is connected by a telescopic column, and its angle can be adjusted. When moving, the connecting block at the bottom of the laser head slides along the inside of the slide groove and is guided by the soft strip, so that the distance between the laser head and different positions of the shaft part body is close. When the shaft part body is sent out, the rear plate will be pulled to the entrance end of the limit assembly. In this process, the inclined plates on both sides of the rear plate first contact the soft strip, and the insertion rod is pushed outward by the action of the inclined surface, and then the soft strip is squeezed by the pressure plate to restore the initial state of the limit assembly, which is convenient for the next group of cladding processing.

[0019] 4. The present invention clamps one end of the shaft part body by the bidirectional electric push rod and the clamping block on the surface of the front plate, then turns on the motor to drive the first screw to rotate, and the slide seat at the bottom of the front plate cooperates with the first screw thread to slide along the slide rail until the other end of the shaft part body is connected to the rear plate, and then the shaft part body is clamped and fixed by the clamping block of the rear plate. This structure can be used to fix shaft parts of different lengths, and also saves time for adjusting the clamp. During the cladding and movement process, the shaft part body is driven by the driving motor and the turntable to rotate, so that the heat generated by the heating rod preheats the surface of the shaft part body, and also improves the efficiency of cladding. The movement of the rear plate relies on the advancement of the unidirectional electric push rod.

[0020] 5. Compared with the prior art, the present invention clamps and fixes the parts through a clamping assembly and sends them to the welding position. The soft strip of the limiting assembly is wrapped around the two sides of the parts to match the shape of the parts to form a slideway.

The base 1 is located on the top of the shaft part body 6 and is fixed with a top frame 2. When using the device, one end of the shaft part body 6 is clamped on the front plate 31, and then the shaft part body 6 is pushed into the limiting component 5 along the slide rail 34 to dock with the rear plate 33. The soft strip 55 of the limiting component 5 wraps the side of the shaft part body 6 to form a guide channel. The laser device moves along the surface of the soft strip 55 to clad the surface of the shaft part body 6.

This structure can be used for fixing shaft part bodies 6 of different lengths, and also saves time for adjusting the fixture. During the cladding and moving process, the shaft part body 6 is driven to rotate by the driving motor 32 and the turntable 39, so that the heat generated by the heating rod 21 preheats the surface of the shaft part body 6, and also improves the efficiency of cladding. The movement of the rear plate 33 relies on the advancement of the one-way electric push rod 37.

[0034] In this embodiment, the limit assembly 5 also includes a third spring 53, the plug rod 52 is located on the outer surface of the side plate 51 and is sleeved with the third spring 53, and the two ends of the third spring 53 are respectively fixedly connected to the side plate 51 and the plug rod 52, and the two ends of the side plate 51 are fixed with a winding seat 54, and the two ends of the soft strip 55 are wound inside the winding seat 54 through the winding shaft and the torsion spring, and a connecting groove 56 is opened on the top surface of the soft strip 55, and a connecting block 57 is slidably connected to the bottom of the laser head 49 inside the sliding groove 56, and a telescopic column 58 is fixed on the top of the connecting block 57. The top of the telescopic column 58 is rotatably connected to the bottom of the laser head 49 through a rotating shaft. In the initial stage, the rear plate 33 is located at the entrance end of the limiting assembly 5. At this time, the soft strip 55 is pressed near the side plate 51 by the pressure plates 313 on both sides of the rear plate 33, and the opening of the limiting assembly 5 is maximized. As the front plate 31 clamps the shaft part body 6 and moves to dock with the rear plate 33, the front plate 31 and the rear plate 33 slide synchronously along the slide rail 34, and the shaft part body 6 is sent into the interior of the limiting assembly 5. After part of the soft strip 55 is no longer restricted by the pressure plate 313, the insertion rod 52 passes through the side plate 51 through the elastic force of the third spring 53. The soft strip 55 is attached to the surface of the shaft part body 6, maintaining the same shape as its concave and convex, until the shaft part body 6 completely enters the interior of the limit assembly 5, and the soft strip 55 is also completely wrapped on both sides of the shaft part body 6. In this process, in order to ensure that the soft strip 55 can be attached to the surface of the shaft part body 6, the winding seats 54 at both ends can unwind the length of the soft strip 55 according to the needs of the soft strip 55. The winding seats 54 can be fixed by bolts to prohibit further winding and unwinding, so as to keep the length of the soft strip 55 fixed, thereby facilitating the movement of the laser head 49. The bottom of the laser head 49 is connected by a telescopic column 5 8 connection, its angle can be adjusted, when moving, the connecting block 57 at the bottom of the laser head 49 slides along the inside of the slide groove 56, and is guided by the soft strip 55, so that the distance between the laser head 49 and different positions of the shaft part body 6 is close, and when the shaft part body 6 is sent out, the rear plate 33 will be pulled to the entrance end of the limit assembly 5. In this process, the inclined plates 314 on both sides of the rear plate 33 first contact with the soft strip 55, and the insertion rod 52 is pushed outward by the action of the inclined surface, and then the soft strip 55 is squeezed by the pressing plate 313 to restore the initial state of the limit assembly 5, so as to facilitate the next group of cladding processing.

[0035] In this embodiment, the laser assembly 4 also includes a second screw 44, the second screw 44 is rotatably installed inside the slide frame 43 through a bearing, and the slider 45 is threadedly sleeved on the surface of the second screw 44, and a plug plate 46 is slidably inserted at the bottom of the slider 45, and a mounting seat 48 is fixed to one end of the plug plate 46 facing the laser head 49, and the tail end of the laser head 49 is rotatably connected to the mounting seat 48 through a rotating shaft, and a second spring 47 is fixed to the outer end of the plug plate 46, and the other end of the second spring 47 is fixedly connected to the slider 45. The laser assembly 4 is an existing synchronous laser cladding, and the powder or wire cladding material is synchronously sent into the molten pool through the nozzle during the cladding process through the cooperation of the output box 41 and the hose 42. In this process, in order to cooperate with the movement of the laser head 49, the hose 42 needs to reserve a certain length to meet the movement range of the laser head 49, and the hose 42 also needs to be made of high temperature resistant material. The laser head 49 of the present device refers to the technical method in CN112589275A, and is connected to the laser cleaning head, the laser texturing head and the laser cladding head through three different laser channels. By turning on and off the corresponding channels, laser cleaning, laser texturing and laser cladding are respectively realized. The action distance of the three parts of laser cleaning, laser texturing and laser cladding on shaft parts does not exceed 2mm. The purpose of this is to give full play to the effectiveness of each step, avoid the appearance of a short-term oxide layer, and further improve the surface bonding force. The second screw 44 is driven by a motor to rotate, and the slider 45 and the second screw 44 are threadedly matched to move along the slide frame 43. The laser head 49 is driven to move horizontally through the plug plate 46 and the mounting seat 48. In this process, the plug plate 46 slides out along the bottom of the slider 45 through the guidance of the soft strip 55, so as to keep the distance between the laser head 49 and different positions of the shaft part body 6 close.

[0036] When using the device, after one end of the shaft part body 6 is clamped by the two-way electric push rod 310 and the clamping block 36 on the surface of the front plate 31, the motor is turned on to drive the first screw 35 to rotate, and the slide seat 38 at the bottom of the front plate 31 and the first screw 35 threadedly cooperate to slide along the slide rail 34 until the other end of the shaft part body 6 is docked on the rear plate 33, and the shaft part body 6 is clamped and fixed by the clamping block 36 of the rear plate 33. This structure can be used for fixing shaft part bodies 6 of different lengths, and also saves time for adjusting the fixture. During the cladding and moving process, the shaft part body 6 is driven to rotate by the driving motor 32 and the turntable 39, so that the heat generated by the heating rod 21 preheats the surface of the shaft part body 6, and also improves the efficiency of cladding. The movement of the rear plate 33 relies on the advancement of the one-way electric push rod 37. When moving, the connecting block 5 at the bottom of the laser head 49 7 slides along the inside of the slide groove 56 and is guided by the soft strip 55, so that the distance between the laser head 49 and different positions of the shaft part body 6 is close. When the shaft part body 6 is sent out, the rear plate 33 will be pulled to the entrance end of the limit assembly 5. In this process, the inclined plates 314 on both sides of the rear plate 33 first contact with the soft strip 55, and the insertion rod 52 is pushed outward by the action of the inclined surface, and then the soft strip 55 is squeezed by the pressure plate 313 to restore the initial state of the limit assembly 5, so as to facilitate the next group of cladding processing. The second screw rod 44 is driven to rotate by the motor, and the slider 45 and the second screw rod 44 are threadedly matched to move along the slide frame 43, and the laser head 49 is driven to move horizontally by the insertion plate 46 and the mounting seat 48. In this process, the insertion plate 46 slides out along the bottom of the slider 45 through the guidance of the soft strip 55, so as to keep the distance between the laser head 49 and different positions of the shaft part body 6 close.
