Description

Technical Field

[0001] This utility model belongs to the field of laser cutting technology for wear-resistant rings, and specifically relates to a laser cutting device for processing wear-resistant rings. Background Technology

[0002] Wear rings are key components commonly used in mechanical equipment. They are mainly used to reduce friction, protect other components, and improve the service life of equipment. Wear rings need to be laser-cut during processing to form slits. The main purpose of the slit design in wear rings is to cope with the thermal expansion of materials, mechanical deformation, and installation requirements, while also taking into account sealing performance and operational stability.

[0003] Existing laser cutting equipment for processing wear-resistant rings uses clamps to hold and fix the wear-resistant ring in order to maintain its position during laser cutting. This creates a kerf during the cutting process. As the kerf length increases, the structural strength of the wear-resistant ring to maintain its ring shape decreases. Under the clamping force, the wear-resistant ring will squeeze the kerf, causing deformation and loosening, resulting in displacement of the cut and affecting the cutting accuracy.

[0004] Therefore, a laser cutting device for processing wear-resistant rings is proposed. Summary of the Invention

[0005] This invention provides a laser cutting device for processing wear-resistant rings, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a laser cutting device for processing wear-resistant rings, including a working platform; a feeding hole opened at the top of the working platform; a stepper motor disposed on one side of the outer wall of the working platform; a feeding tray fixed to the output end of the stepper motor; a wear-resistant ring placed above the feeding tray; a cutting assembly and a limiting assembly disposed on the working platform; wherein, the cutting assembly includes: a horizontal electric push rod disposed on the outer wall of the working platform adjacent to the stepper motor; a moving plate fixed to the output end of the horizontal electric push rod; guide blocks symmetrically disposed on the outer wall of the moving plate; a three-phase motor disposed at the top of the moving plate; a lead screw fixed to the output end of the three-phase motor; a moving stage disposed on the lead screw; a laser welding head and a kerf filling plate disposed on one side of the outer wall of the moving stage, the laser welding head being located above and to the side of the kerf filling plate; and a kerf groove opened on the outer wall of the feeding tray, the kerf groove and the kerf filling plate overlapping.

[0007] Furthermore, the limiting component includes a vertical electric push rod located at the top of the working platform. A lifting ring is fixedly connected to the output end of the vertical electric push rod. A limiting rod and a wedge block 1 are provided at the top of the lifting ring. The limiting rod is located on one circumferential side of the wedge block 1. A through groove is opened at the top of the working platform. A wedge block 2 is slidably connected inside the through groove. A spring is provided between the wedge block 2 and the through groove. A connecting rod is provided on one outer wall of the wedge block 2. A clamping block is provided at one end of the connecting rod.

[0008] Furthermore, the bottom of the working platform is provided with a base, the top of the base is provided with a feeding platform, and the top of the feeding platform is provided with an inclined slope.

[0009] By adopting the above technical solution, the inclined surface can be used to guide the falling wear-resistant ring downwards, thereby realizing the feeding of the wear-resistant ring.

[0010] Furthermore, the top of the work platform is provided with a groove for the movable plate to move, and the groove and the guide block are slidably connected;

[0011] By adopting the above technical solution, the stability of the moving plate can be ensured by sliding the moving plate on the working platform, thereby adjusting the distance between the moving plate and the feeding tray, so that the cutting and filling plate can be separated from the feeding tray.

[0012] Furthermore, the lead screw, the slit filler plate, and the slit groove all form a 45-degree angle with the horizontal plane;

[0013] By adopting the above technical solution, the wear-resistant ring can be cut at a 45-degree angle, ensuring that the cut is inclined and that the wear-resistant ring can expand and contract with temperature changes.

[0014] Furthermore, the top of the wedge one and the bottom of the wedge two are respectively provided with horizontally inclined walls;

[0015] By adopting the above technical solution, the squeezing force between wedge one and wedge two can be redirected by the inclined wall, thereby enabling the vertically moving wedge one to push wedge two to move horizontally.

[0016] Furthermore, the limiting rod passes through the top of the unloading platform;

[0017] By adopting the above technical solution, the limiting rod can pass through the unloading platform, allowing the limiting rod to play a guiding role, thereby enabling the lifting ring to rise and fall vertically.

[0018] Furthermore, an arc surface matching the outer wall of the wear-resistant ring is formed on one side of the outer wall of the clamping block;

[0019] By adopting the above technical solution, the clamping block can be in close contact with the wear-resistant ring, thereby increasing the friction and ensuring the stable and firm clamping of the wear-resistant ring.

[0020] The beneficial effects of this utility model are as follows:

[0021] This invention utilizes a slit filler plate that moves synchronously along the trajectory of the laser welding head. This allows the filler plate to gradually insert into the slit during the laser cutting process of the wear-resistant ring, filling the slit and preventing deformation caused by the gradual decrease in structural strength during laser cutting. This effectively ensures the stability of the wear-resistant ring's position during cutting, avoiding low cutting accuracy due to ring misalignment. Furthermore, the flip-type unloading tray allows for automatic unloading of the cut wear-resistant ring, eliminating the need for manual unloading and increasing efficiency.

The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Example 1

[0032] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 This utility model embodiment proposes a laser cutting device for processing wear-resistant rings, including a working platform 3, a base 1 at the bottom of the working platform 3, and a feeding platform 2 at the top of the base 1. The feeding platform 2 has an inclined surface at the top, which can guide the falling wear-resistant ring 7 downwards, thereby realizing the feeding of the wear-resistant ring 7.

[0033] The top of the working platform 3 has a circular feeding hole 4, and a stepper motor 5 is bolted to one side of the outer wall of the working platform 3. The stepper motor 5 is fixedly connected to a feeding tray 6 through its output end. A wear-resistant ring 7 is placed on the top of the feeding tray 6. A horizontal electric push rod 81 from the cutting assembly 8 is bolted to the center of the outer wall of the working platform 3 adjacent to the stepper motor 5. A moving plate 82 is fixedly connected to the horizontal electric push rod 81 through its output end. A three-phase motor 83 is bolted to the top of the moving plate 82. A lead screw 84 is fixedly connected to the three-phase motor 83 through its output end. A moving table 86 is fixedly connected to the nut seat on the lead screw 84 by screws. A laser welding head 8 is provided on one side of the outer wall of the moving table 86. 7 and the kerf filling plate 88, the laser welding head 87 is located on the side above the kerf filling plate 88, two guide blocks 85 are symmetrically arranged on the outer side wall of the moving plate 82, the top of the working platform 3 is provided with a groove for the moving plate 82 to move, the groove and the guide block 85 are slidably connected, by the sliding of the moving plate 82 on the working platform 3, the stability of the moving plate 82 can be ensured, thereby adjusting the distance between the moving plate 82 and the unloading plate 6, so that the kerf filling plate 88 can be separated from the unloading plate 6. A kerf groove 89 is provided on one side of the outer wall of the unloading plate 6. The lead screw 84, the kerf filling plate 88 and the kerf groove 89 are all at a 45-degree angle to the horizontal plane. Through the 45-degree tilt angle, the wear ring 7 can be cut, ensuring that the cutting kerf is in an inclined state, and ensuring that the wear ring 7 can expand and contract with cold and heat.

[0034] Specifically, when laser cutting the wear-resistant ring 7, the wear-resistant ring 7 is placed on the feeding tray 6 and positioned and clamped. The horizontal electric push rod 81 is controlled to drive the moving plate 82 to move toward the wear-resistant ring 7 through its output end on one side. As the moving plate 82 moves, the kerf filling plate 88 moves synchronously and inserts into the kerf groove 89 on the feeding tray 6. At this time, the kerf filling plate 88 is below the wear-resistant ring 7. At this time, the laser welding head 87 is controlled to laser cut the wear-resistant ring 7. The three-phase motor 83 is controlled to drive the lead screw 84 to rotate through its output end on one side. The guide block 85 on the lead screw 84 moves upward along the moving plate 82 at an angle of 45 degrees. The laser welding head 87 and the kerf filling plate 88 move synchronously. The laser welding head 87 cuts the wear-resistant ring 7 and forms an inclined kerf. After the cutting is completed, the moving plate 82 is controlled to reset, and the kerf filling plate 88 is removed from the wear-resistant ring 7. At this time, the kerf filling plate 88 is located outside the feeding tray 6.

[0035] Subsequently, the clamping of the feeding tray 6 is released, and the stepper motor 5 is controlled to drive the feeding tray 6 to rotate 90 degrees through its output end on one side. At this time, the feeding tray 6 is at a 90-degree angle to the horizontal plane, and the wear-resistant ring 7 on the feeding tray 6 falls onto the feeding platform 2 under its own gravity. Through the inclined surface on the feeding platform 2, the falling wear-resistant ring 7 can be tilted downwards and guided, thereby realizing the feeding of the wear-resistant ring 7 and achieving automatic feeding.

[0036] Example 2

[0037] Reference Figure 1-3 This utility model embodiment also proposes a laser cutting device for processing wear-resistant rings, including a working platform 3. A vertical electric push rod 91 from a limit assembly 9 is installed on the top of the working platform 3. A lifting ring 92 is fixedly connected to the output end of the vertical electric push rod 91. A limit rod 93 and a wedge block 94 are installed on the top of the lifting ring 92. The limit rod 93 passes through the top of the unloading platform 2, allowing it to guide the lifting ring 92 vertically. The limit rod 93 is located on one circumferential side of the wedge block 94. A through groove is provided on the top of the working platform 3, and a second wedge block 94 is slidably connected inside the through groove. 5. The top of wedge 1 94 and the bottom of wedge 2 95 are respectively provided with horizontally inclined walls. The inclined walls can redirect the squeezing force of wedge 1 94 and wedge 2 95, so that the vertically moving wedge 1 94 can push wedge 2 95 to move horizontally. A spring 96 is provided between wedge 2 95 and the through groove. A connecting rod 97 is provided on one side of the outer wall of wedge 2 95. A clamping block 98 is provided at one end of the connecting rod 97. An arc surface matching the outer wall of the wear-resistant ring 7 is provided on one side of the outer wall of the clamping block 98, so that the clamping block 98 can be in close contact with the wear-resistant ring 7, thereby increasing the friction and ensuring that the wear-resistant ring 7 is clamped stably and firmly.

[0038] Specifically, before laser cutting the wear-resistant ring 7, the wear-resistant ring 7 is placed on the feeding tray 6. The vertical electric push rod 91 is controlled to drive the lifting ring 92 upward through its output end on one side. Under the vertical guidance of the limit rod 93, the lifting ring 92 rises steadily and vertically. The four wedges 94 on the top of the lifting ring 92 move upward synchronously. The inclined walls on the wedges 94 and 95 can convert the vertical force into the horizontal force when they come into contact, thereby pushing the wedges 94 to move horizontally. At this time, the connecting rod 97 and the clamping block 98 on the wedges 94 move synchronously. The clamping block 98 extends above the feeding tray 6, and the four clamping blocks 98 clamp the wear-resistant ring 7 synchronously to ensure the stability of the wear-resistant ring 7 during cutting.
