Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding feeding, in particular to a feeding guide rail used for laser cladding. Background Art

[0002] Laser cladding, also known as laser melting or laser cladding, is a new surface modification technology. It forms a metallurgically bonded cladding layer on the surface of the base by adding cladding material to the surface of the substrate and using a high-energy-density laser beam to melt it together with a thin layer on the surface of the substrate. Laser cladding will generate high heat and high-intensity light during the working process, and will spray powder at the same time. In order to increase the safety of the operator, a feeding guide is usually used to feed the workpiece to be laser clad into the laser cladding equipment.

[0003] The utility model with the existing authorization announcement number CN215393268U discloses a laser cladding tooling, including a floor, a fixing clamping structure is installed on the top of the floor; wherein the fixing clamping structure includes: a plurality of anchor bolts, a fixing block A, a top plate A2 block, a fixing block B, a slider, a seat block, a cylinder and a workpiece; the floor is fixed to the ground by a plurality of the anchor bolts, and the fixing block A is connected to one side of the top of the floor by screws.

[0004] The above technical solution is adopted to solve the problem in the prior art that, during the laser cladding process, due to the small laser spot, the position to be welded is required to have high precision, and the workpiece needs to be continuously adjusted and moved so that the weld on the workpiece coincides with the moving trajectory of the laser spot. However, in the above technical solution, the feeding guide for laser cladding has great limitations when used. Usually, the workpiece is only fed into the laser cladding equipment or simply moved back and forth. The trajectory movement during the laser cladding process is completely achieved by the laser cladding nozzle, resulting in some workpieces that require comprehensive laser cladding cannot complete the laser cladding work of the top surface, front and back surfaces and bottom surfaces in a single feeding process. The feeding guide needs to move back and forth and then manually adjust the workpiece position to achieve a more comprehensive laser cladding work, which greatly affects the laser cladding efficiency of the workpiece.

[0027] Two movable plates 3 are arranged above the feed rack 2, and the internal rotation of the feed rack 2 is connected with a bidirectional screw 4, and the internal thread of the guide rail frame 1 is connected with four mounting bolts 15, and the bottom end of each mounting bolt 15 passes through the guide rail frame 1 and extends to the bottom of the guide rail frame 1. The mounting bolts 15 can fix the position of the guide rail frame 1, so that the guide rail frame 1 can be conveniently installed on the laser cladding equipment, ensuring the installation firmness of the guide rail frame 1.

[0028] The outer surface of the bidirectional screw 4 is threadedly connected to two moving blocks 5, each of which is slidably connected to the inside of the feeding rack 2, and the upper surface of each moving block 5 is fixedly connected to the bottom surface of the moving plate 3. The upper surface of the feeding rack 2 is provided with two auxiliary grooves 16, and the inside of each auxiliary groove 16 is slidably connected to two auxiliary blocks 17, and the upper surface of each auxiliary block 17 is fixedly connected to the bottom surface of the moving plate 3. The auxiliary blocks 17 slide inside the auxiliary grooves 16, which can increase the stability of the forward and backward movement of the moving plate 3, make the moving plate 3 less likely to shake during the movement, and improve the use accuracy of the moving plate 3.

[0029] A first servo motor 6 is fixedly connected to the front of the feeding rack 2, and the output end of the power of the first servo motor 6 is fixedly connected to one end of the bidirectional screw 4 close to the first servo motor 6. A bearing frame 18 is sleeved on the outer surface of the bidirectional screw 4, and the bearing frame 18 is fixedly embedded in the inside of the feeding rack 2. The bearing frame 18 can assist the rotation of the bidirectional screw 4 and increase the rotation stability of the bidirectional screw 4. At the same time, it can limit the sliding position of the moving block 5 to prevent the moving block 5 from sliding to a position where there is no thread on the bidirectional screw 4.

[0030] The upper surface of each movable plate 3 is fixedly connected to a second servo motor 7, the output end of each second servo motor 7 power is fixedly connected to a rotating screw 8, the outer surface of each rotating screw 8 is threadedly connected to a fixed plate 9, the side of the two movable plates 3 away from each other are fixedly connected to a bearing frame 19, the side of the two fixed plates 9 away from each other are fixedly connected to two stabilizing blocks 20, each stabilizing block 20 is slidably connected to the inside of the bearing frame 19, and the stabilizing block 20 moves up and down inside the bearing frame 19, which can increase the horizontal bearing capacity of the fixed plate 9 without affecting the up and down movement of the fixed plate 9, so that the fixed plate 9 is not prone to displacement and deformation when the horizontal bearing capacity is applied.

The side surfaces of the two groups of positioning frames 22 that are away from each other are respectively fixedly connected to the side surfaces of the two fixed plates 9 that are close to each other.

[0032] The side surfaces of the two clamping columns 11 that are close to each other are fixedly connected with anti-skid pads 23, and the side surfaces of the two anti-skid pads 23 that are close to each other are provided with anti-skid grooves 24 arranged at equal distances. The anti-skid pads 23 and the anti-skid grooves 24 can increase the stability of the clamping columns 11 when clamping the workpiece, making it difficult for the workpiece to loosen from the clamping columns 11, thereby ensuring the stability of the workpiece during laser cladding operation.

After the workpiece is clamped and fixed, the power provided by the fourth servo motor 14 cooperates with the guide rail frame 1 to drive the feeding screw 12 to rotate, and the threaded connection relationship between the feeding screw 12 and the connecting block 13, as well as the sliding limit of the connecting block 13 inside the guide rail frame 1, can drive the feeding frame 2 to move back and forth, so that the clamped and fixed workpiece can be smoothly sent into the processing position inside the laser cladding equipment. When the laser cladding processing of the top surface of the workpiece is completed, the workpiece can be turned over by using the power provided by the third servo motor 10 in conjunction with the fixed plate 9 to drive the clamping column 11 to rotate one hundred and eighty degrees or ninety degrees under the pressure assistance of the auxiliary bearing 21 and the positioning frame 22, so that the laser cladding feeding guide can complete multi-sided processing of the workpiece with one feeding, and there is no need for the feeding guide to repeatedly discharge and feed materials to adjust the position of the workpiece, which greatly increases the laser cladding efficiency of the workpiece. In addition, the power provided by the second servo motor 7 in conjunction with the moving plate 3 can drive the rotating screw 8 to rotate.
