Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a clamping device for laser cladding. Background Art

[0002] Laser cladding is an advanced material surface modification technology that utilizes a high-energy-density laser beam to rapidly melt alloys with different compositions and properties onto the substrate surface, resulting in a rapid solidification process that forms an alloy layer with completely different composition and properties from the substrate. This technology adds cladding material to the substrate surface and uses the high energy of the laser beam to fuse it together with the thin layer on the substrate surface, thereby forming a metallurgically bonded cladding layer on the base surface. The clamping device used in laser cladding is an indispensable key component in laser cladding technology. It is responsible for stably and accurately clamping the workpiece during the laser cladding process to ensure smooth processing and stable processing quality.

The existing device includes a roller laser cladding repair body, a roller clamping mechanism moving adjustment unit, and a roller clamping fixing unit. The upper surface of the roller laser cladding repair body is provided with a clamping plate, and the upper surface of the clamping plate is provided with a roller clamping mechanism moving adjustment unit. The roller clamping mechanism moving adjustment unit includes a roller clamping fixing unit on the fixed vertical plate 1 and the fixed vertical plate 2. The unit includes a fixed vertical plate 1, a movable sliding column, a fixed vertical plate 2, a movable slider, a limiting circular hole, a clamping cylinder, a connecting plate and a limiting cylinder. When clamping the roller, it is convenient to rotate the roller, and laser cladding repair can be performed on different positions of the roller. It is more convenient to fix rollers of different lengths. However, the existing device does not take into account that the laser cladding body will be worn out after long-term use, and it is not easy to maintain. The cost of replacing a new device is high. In addition, the laser cladding body of the existing device is fixed and can only work on the same position, which has limitations.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-5The utility model provides a technical solution: a clamping device for laser cladding, comprising a base 1, a support frame 2 is mounted on the upper end of the base 1, and a handle 3 is mounted on the lower right end of the support frame 2, a bidirectional screw rod 4 is connected to the left end of the handle 3, and both left and right ends of the bidirectional screw rod 4 are symmetrically mounted with limit blocks 5, a first motor 6 is mounted on the right end of the right limit block 5, and a rotating shaft 7 is connected to the left end of the first motor 6, a shell 8 is mounted on the left end of the rotating shaft 7, and an electric telescopic rod is arranged inside the shell 8 9. Support rods 10 are symmetrically installed at the upper and lower ends of the shell 8, and the support rods 10 are connected to the clamping claws 11. The support frame 2 is rotatably connected to the bidirectional screw rod 4, and the bidirectional screw rod 4 is threadedly connected to the limit block 5. A slide groove is provided at the upper end of the base 1, and the limit block 5 is slidably connected to the slide groove. The proximal ends of the limit block 5 are rotatably connected to the rotating shaft 7, and the proximal end of the rotating shaft 7 is fixedly connected to the shell 8. The upper and lower ends of the shell 8 are fixedly connected to the support rods 10, and the support rods 10 are slidably connected to the clamping claws 11. When the handle 3 is rotated, the two groups of limit blocks 5 move toward both ends or the middle end at the same time, and the electric telescopic rod 9 drives the connecting rod 12 to move horizontally, and the connecting rod 12 is rotated and connected with the clamping jaw 11, so that the clamping jaw 11 slides inside the support rod 10, and the clamping jaw 11 expands or contracts to clamp the workpiece, and cooperates with the movement of the limit block 5 to clamp and fix the workpiece, thereby increasing the precision of the device and improving the quality of the workpiece. The first motor 6 drives the right rotating shaft 7 to rotate, which can drive the workpiece to rotate and work on different positions of the workpiece. The rotation of the workpiece causes the left clamping jaw 11 to drive the left rotating shaft 7 to rotate on the limit block 5, thereby meeting the rotation conditions of the workpiece.

[0032] A second motor 13 is installed at the upper right end of the support frame 2, and a reciprocating screw 14 is connected to the left end of the second motor 13. The support frame 2 is rotatably connected to the reciprocating screw 14, and the upper inner end of the support frame 2 is fixedly connected to the limit rod 15. A slider 16 is provided on the outer sleeve of the reciprocating screw 14, and the slider 16 is threadedly connected to the reciprocating screw 14, and the slider 16 is slidably connected to the limit rod 15. The reciprocating screw 14 is driven to rotate by the second motor 13, and the slider 16 is threadedly connected to the reciprocating screw 14. At the same time, the slider 16 is slidably connected to the limit rod 15.

It can work on different horizontal positions of the workpiece, thereby improving the practicality of the device.

[0033] The lower end of the slider 16 is fixedly connected to a fixing block 17, and the left and right ends of the fixing block 17 are both engaged with the clamping block 18.

[0034] Working principle: When using the clamping device for laser cladding, the handle 3 is rotated to drive the bidirectional screw 4 to rotate, so that the limit blocks 5 at both ends move at the same time. When the limit blocks 5 move to a position suitable for fixing the workpiece, the electric telescopic rod 9 is extended and retracted to drive the connecting rod 12 to move. The connecting rod 12 drives the clamping claw 11 to slide on the support rod 10 to expand and contract, which can fix the workpiece. The first motor 6 is used to drive the right rotating shaft 7 to rotate, so that the workpiece rotates, and work can be performed on different positions of the workpiece. The second motor 13 is used to drive the reciprocating screw 14 to rotate, and the slider 16 is threadedly connected to the reciprocating screw 14. The slider 16 is slidably connected to the limit rod 15, so the reciprocating screw 14 drives the slider 16 to move horizontally, and at the same time drives the laser cladding body 22 to move horizontally, so that work can be performed on different horizontal positions of the workpiece, increasing the practicality of the device. The bolt 20 can be removed by rotating the bolt 20. The bolt 20 passes through the block 18, and the block 18 can be taken out from both ends. The lower end of the block 18 is engaged with the laser cladding body 22, thereby releasing the fixation of the laser cladding body 22 and disassembling the laser cladding body 22, which is convenient for cleaning and maintenance of the laser cladding body 22, increasing the service life of the device and improving work efficiency.
