[0001] This utility model belongs to the field of laser cladding technology, and in particular relates to a workpiece positioning device for laser cladding of inner holes. Background Technology

[0002] Laser cladding is a novel surface modification technology that uses a laser beam to heat the surface of the cladding material and substrate, thereby fusing the desired special material onto the workpiece surface. As an advanced surface modification technology, laser cladding has broad application prospects and enormous development potential.

[0003] In order to support and position the workpiece during laser cladding of the inner hole of the workpiece, a workpiece positioning device for laser cladding of inner hole is designed. During the laser cladding of inner hole of the workpiece by the support plate, the device uses two arc-shaped clamping plates to clamp the workpiece relative to each other, so that the workpiece can be supported and positioned, thus supporting and positioning the workpiece during processing and keeping the workpiece stable and avoiding shaking. Utility Model Content

[0006] Preferably, a motor is fixedly connected to the bottom of the hollow support groove cavity by bolts, and the output shaft of the motor is fixedly connected to the bottom end of the threaded rod by a flange.

[0007] Preferably, the left and right sides of the inner cavity of the bracket are fixedly connected to supporting round rods, and the front and rear ends of the supporting round rods are rotatably connected to reinforcing supporting plates.

[0008] Preferably, the top of each of the reinforcing support plates is rotatably connected to the bottom of the arc-shaped clamping plate, and the inner cavity of each of the two arc-shaped clamping plates is provided with a circular groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses a starting motor to drive the threaded rod to rotate, which in turn causes the hollow movable block to pull the L-shaped support plate to deflect through the connecting plate. This causes the two arc-shaped clamping plates to slide relative to each other and support and position the workpiece. This achieves the purpose of supporting and positioning the workpiece in the processing state, so as to keep the workpiece stable during processing and avoid shaking.

[0013] 2. By setting the rolling round rod, this utility model can enable the workpiece to rotate while the two arc-shaped clamping plates are clamping and positioning the workpiece, thus avoiding the situation where the workpiece cannot rotate normally due to excessive clamping force of the two arc-shaped clamping plates.

[0014] 3. By raising the support base, this utility model can increase the contact area between the bottom of the tooling lathe and the ground during operation of the support plate and the cladding device, making the tooling lathe more stable when supporting the support plate and the cladding device.

[0022] In the following description, embodiments of the workpiece positioning device for laser cladding of inner holes according to the present invention will be described with reference to the accompanying drawings.

[0023] Example 1:

[0024] Figure 1-4 This invention illustrates a workpiece positioning device for laser cladding of inner holes according to an embodiment of the present invention. The device includes: a hollow support groove 2 fixedly connected to the inner cavity of a tooling lathe 1 by bolts; a bracket 3 fixedly connected to the inner cavity of the hollow support groove 2 by bolts; a threaded rod 4 rotatably connected to the inner cavity of the bracket 3; a hollow movable block 5 threadedly connected to the surface of the threaded rod 4; hollow connecting supports 6 welded to both sides of the hollow movable block 5; L-shaped support plates 7 rotatably connected to both sides of the inner cavity of the bracket 3; a connecting plate 8 rotatably connected between the L-shaped support plate 7 and the hollow movable block 5; and an arc-shaped clamping plate 9 rotatably connected to the inner cavity of the top of the L-shaped support plate 7. The bottom of the bracket 3 is fixedly connected to a motor 10 by bolts. The output shaft of the motor 10 is fixedly connected to the bottom end of the threaded rod 4 through a flange. Supporting round rods 11 are fixedly connected to the left and right sides of the inner cavity of the bracket 3. Reinforcing support plates 12 are rotatably connected to the front and rear ends of the supporting round rods 11. The inner cavities of the two arc-shaped clamping plates 9 are each provided with circular grooves 13. Rolling round rods 14 are rotatably connected to the inner cavities of the circular grooves 13. By setting the rolling round rods 14, the workpiece can still rotate during the clamping and positioning process of the two arc-shaped clamping plates 9. This can avoid the situation where the workpiece cannot rotate normally due to excessive clamping force of the two arc-shaped clamping plates 9.

[0025] Example 2:

[0026] Figure 1-4This invention illustrates a workpiece positioning device for laser cladding of inner holes according to an embodiment of the present invention. The device includes: a hollow support groove 2 bolted to the inner cavity of a tooling lathe 1; a bracket 3 bolted to the inner cavity of the hollow support groove 2; a threaded rod 4 rotatably connected to the inner cavity of the bracket 3; a hollow movable block 5 threaded to the surface of the threaded rod 4; hollow connecting supports 6 welded to both sides of the hollow movable block 5; L-shaped support plates 7 rotatably connected to both sides of the inner cavity of the bracket 3; a connecting plate 8 rotatably connected between the L-shaped support plate 7 and the hollow movable block 5; and a top of the L-shaped support plate 7... The inner cavity is rotatably connected to an arc-shaped clamping plate 9. The top ends of the two reinforcing support plates 12 are rotatably connected to the bottom of the arc-shaped clamping plate 9. A support plate 15 is installed on the front side of the tooling lathe 1, and a cladding device 16 is installed on the rear side of the tooling lathe 1. The bottom of the tooling lathe 1 is fixedly connected to a raised support seat 17 by bolts. By setting up the raised support seat 17, the contact area between the bottom of the tooling lathe 1 and the ground can be increased during the operation of the support plate 15 and the cladding device 16, so that the tooling lathe 1 can be more stable when supporting the support plate 15 and the cladding device 16.

[0027] Working principle: When using this utility model, the user fixes the workpiece that needs to be reinforced by the support plate 15, then starts the motor 10 to drive the threaded rod 4 to rotate. Then, under the action of the thread, the hollow movable block 5 slides downward, and drives the connecting plate 8 to slide downward. Then, the connecting plate 8 pulls the L-shaped support plate 7 to deflect. At this time, the supporting force of the reinforcement support plate 12 makes the L-shaped support plate 7 push the arc-shaped clamping plate 9 to slide when it deflects. Then, the two arc-shaped clamping plates 9 slide relative to each other, thereby supporting and positioning the workpiece fixedly supported by the support plate 15. This supports and positions the workpiece in the processing state, so that the workpiece remains stable during processing and avoids shaking.

[0028] In summary, this laser cladding inner hole workpiece positioning device uses a starting motor 10 to drive the threaded rod 4 to rotate, which in turn causes the hollow movable block 5 to pull the L-shaped support plate 7 through the connecting plate 8 to deflect, thereby causing the two arc-shaped clamping plates 9 to slide relative to each other and support and position the workpiece. This achieves the purpose of supporting and positioning the workpiece in the processing state, so as to keep the workpiece stable during processing and avoid shaking.
