Description

Technical Field

[0001] This utility model belongs to the field of blade quenching technology, specifically a positioning and clamping fixture for laser quenching of large blades. Background Technology

[0002] In fields such as machinery manufacturing, mining, and building materials processing, large blades are core cutting or crushing components. Their surface hardness and wear resistance directly determine the operating efficiency and service life of the equipment. Laser quenching technology, with its advantages of fast heating speed, uniform quenching layer, and small workpiece deformation, has become a key process for improving the surface performance of large blades.

[0003] However, when traditional blades undergo laser hardening, the clamping mechanism uses vertical clamping plates. This results in insufficient contact between the clamping plates and the blades when clamping irregularly shaped blades, affecting the clamping effect. Furthermore, the blades need to be manually placed under the laser hardener, which poses a safety hazard due to the hands being too close to the laser hardener. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a positioning and clamping fixture for laser quenching of large blades, which effectively solves the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a positioning and clamping fixture for laser quenching of large blades, comprising a base, a fixing frame fixedly installed at the top of the base, a transverse groove opened on the inner top of the fixing frame, an electric slide rail fixedly installed inside the transverse groove, an electric slide block slidably installed outside the electric slide rail, and a laser quencher body fixedly installed at the bottom of the electric slide block.

[0006] Preferably, a first motor is fixedly installed on the outside of the base, a threaded rod is fixedly connected to the drive end of the first motor, a longitudinal groove is opened on the top surface of the base, the threaded rod is rotatably connected inside the longitudinal groove, a displacement block is threaded on the outside of the longitudinal groove, a support plate is fixedly installed on the top of the displacement block, and a blade body is movably installed on the top of the support plate.

[0007] Preferably, rotating shafts are rotatably mounted on both sides of the top surface of the base, and cams are fixedly sleeved on the lower part of each of the two rotating shafts. Driven gears are fixedly connected to the top ends of the two rotating shafts, which extend through to the top of the fixed frame.

[0008] Preferably, a fixing plate is fixedly installed on both sides of the top surface of the fixing frame, and a horizontal shaft is rotatably installed on one end of the fixing plate. A drive gear is fixedly sleeved on both sides of the outer side of the horizontal shaft. The two drive gears are respectively meshed with two driven gears. A second motor is fixedly connected to the extended end of the horizontal shaft to the outside of the fixing plate.

[0009] Preferably, the top surface of the base has convex grooves on both sides, and convex blocks are slidably installed inside the two convex grooves. U-shaped plates are fixedly installed at the top of the two convex blocks. Connecting plates are fixedly installed at one end of the two U-shaped plates. Sliding rods distributed in an array are slidably installed inside the two connecting plates. Clamping pieces are fixedly installed at one end of the multiple sliding rods. Connecting pieces are fixedly installed at the other end of the multiple sliding rods. Clamping springs are fixedly installed at one end of the multiple connecting pieces. One end of the multiple clamping springs is fixedly connected to the corresponding connecting plates.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention utilizes a first motor to rotate a threaded rod, which in turn drives a displacement block to move. The displacement block then moves a support plate, which in turn moves the blade body to a position below the laser quencher body. A second motor rotates a horizontal shaft, which in turn drives a drive gear to rotate. The drive gear then drives a driven gear to rotate, which in turn drives a rotating shaft to rotate a cam. This, in turn, moves an adjusting U-shaped plate. The movement of the U-shaped plate moves a connecting plate, which in turn moves a clamping plate to contact and hold the blade body. By utilizing the sliding action of the sliding rods, combined with the effect of the clamping springs, multiple sliding rods and clamping plates can move independently, thus facilitating the quenching of blade bodies of different shapes. Moreover, this method is more convenient and safer than manual feeding. Attached Figure Description

A support plate 11 is fixedly installed on the top of the displacement block 10, and a blade body 12 is movably installed on the top of the support plate 11. By placing the blade body 12 on the support plate 11, the first motor 7 rotates the threaded rod 8. The rotation of the threaded rod 8 drives the displacement block 10 to move, the displacement block 10 drives the support plate 11 to move, and the support plate 11 then drives the blade body 12 to move below the laser hardener body 6. Subsequently, the electric slide 5 slides on the electric slide rail 4 to drive the laser hardener body 6 to perform laser hardening treatment on the blade body 12. This is more convenient and safer than manual feeding.

[0021] Rotating shafts 13 are rotatably mounted on both sides of the top surface of the base 1. Cams 14 are fixedly sleeved on the lower part of each of the two rotating shafts 13. Driven gears 15 are fixedly connected to the top of the two rotating shafts 13 and extend through them to the top of the fixed frame 2. Fixed plates 16 are fixedly mounted on both sides of the top surface of the fixed frame 2. A horizontal shaft 17 is rotatably mounted on the opposite end of the fixed plate 16. Driving gears 18 are fixedly sleeved on both sides of the outer side of the horizontal shaft 17. The two driving gears 18 are respectively meshed with the two driven gears 15. A second motor 19 is fixedly connected to the extended end of the horizontal shaft 17 and extends to the outside of the fixed plate 16. The second motor 19 rotates the horizontal shaft 17, which drives the driving gears 18 to rotate. The driving gears 18 then drive the driven gears 15 to rotate, thereby driving the rotating shaft 13 to rotate the cams 14, which in turn pushes the adjusting U-shaped plate 22 to move.

[0022] Both sides of the top surface of the base 1 are provided with convex grooves 20. Convex blocks 21 are slidably installed inside the two convex grooves 20. U-shaped plates 22 are fixedly installed at the top of the two convex blocks 21. Connecting plates 23 are fixedly installed at one end of the two U-shaped plates 22.

One end of the multiple clamping springs 27 is fixedly connected to the corresponding connecting plates 23. The movement of the U-shaped plates 22 drives the connecting plates 23 to move. The connecting plates 23 then drive the clamping pieces 25 to contact and clamp the blade body 12. By utilizing the sliding action of the sliding rods 24 and the effect of the clamping springs 27, the multiple sliding rods 24 and clamping pieces 25 can move independently, thereby facilitating the clamping of blade bodies 12 of different shapes for quenching processing.

[0023] Working principle: In use, firstly, the blade body 12 is placed on the support plate 11. Then, the first motor 7 rotates the threaded rod 8, which drives the displacement block 10 to move. The displacement block 10 drives the support plate 11 to move, and the support plate 11 then moves the blade body 12 to below the laser quencher body 6. The second motor 19 rotates the horizontal shaft 17, which drives the drive gear 18 to rotate. The drive gear 18 then drives the driven gear 15 to rotate, which drives the rotating shaft 13 to rotate the cam 14, thereby pushing the adjustment U. The U-shaped plate 22 moves, which drives the connecting plate 23 to move. The connecting plate 23 then drives the clamping piece 25 to contact and clamp the blade body 12. By utilizing the sliding action of the slide rod 24, combined with the effect of the clamping spring 27, multiple slide rods 24 and clamping pieces 25 can move independently, thereby facilitating the clamping of blade bodies 12 of different shapes for quenching. Subsequently, the electric slide block 5 slides on the electric slide rail 4 to drive the laser quencher body 6 to perform laser quenching on the blade body 12. This is more convenient and safer than manual feeding.
