Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically a five-axis laser tooling and fixture. Background Technology

[0002] With the advancement of technology, the automotive industry has developed rapidly in recent years. In automotive production, some metal parts have very strict requirements for dimensional accuracy during processing. They are usually cut using expensive laser cutting technology. Laser cutting uses a high-power-density laser beam to irradiate the material being cut, which quickly heats the material to its vaporization temperature and evaporates to form a hole. As the beam moves across the material, the hole continuously forms a very narrow kerf, completing the cutting of the material.

[0003] Chinese Patent Publication No. CN214921368U discloses a fixture for a laser cutting machine, including a base. Two No. 1 electric cylinders are fixedly connected to the left and right sides of the interior of the base. The two No. 1 electric cylinders are distributed in a front-to-back manner, and the top of the No. 1 electric cylinders extends through to the outside of the base. A fixing plate is fixedly connected above each pair of front-to-back electric cylinders. The fixing plate has a slot inside.

[0004] However, the inventor of the above device believes that there are certain defects. During the use of the above device, due to the diverse and complex shapes of the workpieces and the requirement for high precision, there is a problem of difficulty in positioning. Therefore, this utility model provides a five-axis laser tooling fixture. Utility Model Content

[0005] The purpose of this invention is to provide a five-axis laser tooling fixture to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a five-axis laser tooling fixture, comprising a base plate and two clamping mechanisms. The top of the base plate has a sliding groove, and a sliding seat is slidably connected inside the sliding groove. The sliding seat is provided with a limiting mechanism to restrict the sliding of the sliding seat. A fixed sleeve is fixedly connected to the top of the sliding seat, and a sliding rod is slidably connected inside the fixed sleeve. The clamping mechanism includes a fixed seat fixed to the top of the sliding rod. Two sliding blocks are slidably connected inside the fixed seat. A clamping rod is fixedly connected to the top of each sliding block. A limiting gear is fixedly connected to the sliding rod. The top of the fixed sleeve has a gear groove adapted to the limiting gear, and the gear groove is inserted into the inside of the limiting gear.

[0007] Preferably, the fixed base is internally rotatably connected to a bidirectional screw, and both fixed bases are threaded onto the bidirectional screw. The two fixed bases can be moved closer to each other or further apart by rotating the bidirectional screw.

[0008] Preferably, the clamping rod is cylindrical, and a clamping plate is fitted on the outer surface of the clamping rod. By fitting the clamping plate onto the clamping rod, the two clamping plates can clamp the workpiece whose clamping surface is a plane.

[0009] Preferably, the limiting mechanism includes a movable insert rod that slides on the outer side of the sliding seat, and a fixed insertion hole is provided on the inner wall of the sliding groove. One end of the movable insert rod is inserted into the inside of the fixed insertion hole. By inserting one end of the movable insert rod into the inside of the fixed insertion hole, the sliding seat is limited to slide inside the sliding groove.

[0010] Preferably, a baffle is fixedly connected to one end of the movable plug rod, and a spring is sleeved on the movable plug rod. Under the action of the spring force, the movable plug rod can slide quickly out of the fixed plug hole when it is not under force.

[0011] Preferably, one end of the sliding rod extends into the interior of the sliding seat, and a connecting rod is rotatably connected to the bottom of the sliding rod. A pressing rod is hinged to the outer surface of the connecting rod via a pin, and the other end of the pressing rod is hinged to one side of the baffle via a pin. Under the pressing action of the pressing rod, the two movable insert rods are pushed outward to insert into the interior of the fixed insertion hole.

[0012] Preferably, a base cylinder is fixedly connected inside the sliding seat, and one end of the connecting rod slides inside the base cylinder, which improves the stability of the sliding rod during sliding and rotation under the action of the base cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application clamps the workpiece by controlling two sets of clamping rods on two clamping mechanisms to move closer to each other. By controlling the sliding seat to slide inside the sliding groove, and by pulling the sliding rod upward, the limiting gear is pulled out from inside the gear groove. The tilt angle of the clamping mechanism is adjusted by rotating the sliding rod. It can quickly clamp and fix workpieces of different shapes, and has good adaptability.

[0015] 2. This application uses a bidirectional screw to drive two fixed seats to move closer to each other, thereby quickly clamping and fixing the workpiece. By covering the outer surface of the clamping rod with a clamping plate, it is convenient to clamp and fix workpieces with a flat clamping surface.

[0016] 3. This application uses the sliding rod to slide upwards, thereby releasing the clamping effect of the squeezing rod on one end of the baffle. Then, the spring rebound quickly drives the movable insert rod to be pulled out from the inside of the fixed insert hole, allowing the sliding seat to slide freely inside the sliding groove.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a five-axis laser tooling fixture, including a base plate 1 and two clamping mechanisms 3. The top of the base plate 1 is provided with a sliding groove 11, and a sliding seat 2 is slidably connected inside the sliding groove 11. The sliding seat 2 is provided with a limiting mechanism to restrict the sliding of the sliding seat 2. The limiting mechanism includes a movable insert rod 21 that slides on the outer side of the sliding seat 2. A fixed insertion hole 12 is provided on the inner wall of the sliding groove 11. One end of the movable insert rod 21 is inserted into the inside of the fixed insertion hole 12. By pulling the movable insert rod 21 out from the inside of the fixed insertion hole 12, the sliding seat 2 can slide inside the sliding groove 11 to adjust the distance between the two sliding seats 2.

[0026] Please refer to it again. Figure 1 , Figure 2 and Figure 3 A fixed sleeve 6 is fixedly connected to the top of the sliding seat 2. A sliding rod 7 is slidably connected inside the fixed sleeve 6. The clamping mechanism 3 includes a fixed seat 31 fixed to the top of the sliding rod 7. Two sliding blocks 32 are slidably connected inside the fixed seat 31. A clamping rod 4 is fixedly connected to the top of each sliding block 32. The two sliding blocks 32 are brought closer to each other, so that the two clamping rods 4 clamp and fix the workpiece. A bidirectional screw 33 is rotatably connected inside the fixed seat 31. Both fixed seats 31 are threadedly connected to the bidirectional screw 33. The bidirectional screw 33 is a screw with two external threads. The two external threads are in opposite directions. The two sliding blocks 32 are brought closer to each other or moved away from each other by rotating the bidirectional screw 33.

[0027] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The clamping rod 4 is cylindrical, and the outer surface of the clamping rod 4 is fitted with a clamping plate 5. By fitting the clamping plate 5 onto the clamping rod 4, the two clamping plates 5 can clamp the workpiece whose clamping surface is a plane.

[0028] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A limiting gear 71 is fixedly connected to the sliding rod 7. The top of the fixed sleeve 6 is provided with a gear groove 61 that matches the limiting gear 71. The gear groove 61 is inserted into the inside of the limiting gear 71. The gear groove 61 and the limiting gear 71 restrict the rotation of the sliding rod 7. By pulling the sliding rod 7 up and sliding, the gear groove 61 is pulled out from the inside of the limiting gear 71, and the sliding rod 7 is rotated to adjust the tilt angle value of the clamping mechanism 3.

[0029] Please refer to it again. Figure 1 , Figure 2 and Figure 5One end of the movable insertion rod 21 is fixedly connected to a baffle 22, and a spring 23 is sleeved on the movable insertion rod 21. Under the action of the spring 23, the movable insertion rod 21 is quickly pulled out from the inside of the fixed insertion hole 12 without force. One end of the sliding rod 7 extends into the inside of the sliding seat 2. The bottom of the sliding rod 7 is rotatably connected to a connecting rod 10. The outer surface of the connecting rod 10 is hinged to a pressing rod 9 by a pin. The other end of the pressing rod 9 is hinged to one side of the baffle 22 by a pin. When the sliding rod 7 slides up, the spring 23 rebounds and quickly drives one end of the movable insertion rod 21 to be pulled out from the inside of the fixed insertion hole 12. By pushing the sliding rod 7 down, the pressing action of the pressing rod 9 pushes the movable insertion rod 21 to be reinserted into the inside of the fixed insertion hole 12. The inside of the sliding seat 2 is fixedly connected to a bottom cylinder 8. One end of the connecting rod 10 slides inside the bottom cylinder 8. Under the action of the bottom cylinder 8, the stability of the sliding rod 7 during the lifting or rotation process is improved.

[0030] Working principle: By pulling the fixed base 31 upwards, the limiting gear 71 is pulled out from the inside of the gear groove 61. The tilt angle of the clamping mechanism 3 is adjusted by rotating the sliding rod 7. Under the connection of the connecting rod 10, one end of the pressing rod 9 is driven to rise. The return of the spring 23 causes one end of the movable insert rod 21 to be pulled out from the inside of the fixed insertion hole 12, allowing the sliding base 2 to slide inside the sliding groove 11. The distance between the two clamping mechanisms 3 is adjusted according to the size of the workpiece. After adjustment, the sliding rod 7 is pushed downwards to insert the limiting gear 71 into the inside of the gear groove 61. The connecting rod 10 pushes one end of the pressing rod 9 downwards, and the pressing of the other end of the pressing rod 9 pushes the movable insert rod 21 back into the fixed insert hole 12 to restrict the sliding seat 2 from sliding inside the sliding groove 11, thus completing the adjustment of the tooling. Then, the workpiece to be clamped is placed on top of the two fixed seats 31, and the two clamping rods 4 are driven to move closer to each other by rotating the bidirectional screw 33. Under the action of the two sets of clamping rods 4, the workpiece is quickly clamped and fixed. By putting the clamping plate 5 on the clamping rod 4, the two clamping plates 5 can clamp the workpiece with the clamping surface being flat.
