Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of semi-circular ring processing devices, specifically relating to a cutting device for processing semi-circular rings. Background Technology
[0002] Semi-circular ring parts are used in the cutting head assembly of high-pressure waterjet cutting machines (especially abrasive cutting) as a separate guide or abrasive collection cover surrounding the mixing chamber / nozzle assembly. Their core functions are safety protection (preventing injury from high-speed abrasive and debris splashes) and maintaining a submerged cutting environment (improving cutting performance and reducing noise). In machining semi-circular ring parts, a complete arc-shaped ring is usually produced first, then it is cut into six equal parts using cutting equipment, and the cut semi-circular ring parts are then ground.
[0003] In the segmentation cutting of semi-circular parts such as the guide shroud of a high-pressure water jet cutting machine, traditional processes suffer from clamping stability defects. The thin-walled curved surface structure of the semi-circular ring is prone to deformation due to local stress. Current vises or three-jaw chuck clamping methods are prone to causing workpiece ellipticity deviations due to concentrated clamping force, and the sanded surface can be scratched by the metal clamps. Furthermore, adjusting the cutting angle relies heavily on the operator's experience, and the cumulative error of the six equal angles is relatively large. The semi-circular ring displacement requires manual loosening and relocking of the clamps, resulting in low repeatability and positioning accuracy. This can easily reduce the machining accuracy of the semi-circular ring parts and affect the machining quality. Utility Model Content
[0004] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a cutting device for processing semicircular rings. This cutting device can firmly hold and fix the semicircular ring, effectively avoiding deformation or scratches caused by mechanical clamping tools. The rotating mechanism can drive the adsorption and fixing mechanism and the semicircular ring to rotate 60°, which can effectively improve the positioning accuracy and allow the water-cutting mechanism to cut the semicircular ring again, thereby accurately dividing the semicircular ring into six equal parts. During the cutting process, the semicircular ring parts are still held firmly by the adsorption and fixing mechanism, ensuring cutting accuracy and greatly improving the processing quality of the semicircular ring.
[0005] A cutting device for processing semicircular rings includes a base, a semicircular ring, and a sliding seat. The base has a rotating mechanism inside and a support seat at the top of the rotating mechanism. The sliding seat is slidably connected to the upper surface of the support seat, and its upper surface has an adsorption and fixing mechanism for adsorbing the semicircular ring. The semicircular ring is adsorbed on the top of the adsorption and fixing mechanism. A side support plate is fixedly connected to one side of the upper surface of the base, and an electric telescopic rod is fixedly installed at the top of the side support plate. A fixing frame is fixedly connected to the movable end of the electric telescopic rod. A water-cutting mechanism that can move laterally is provided inside the fixing frame.
[0006] Preferably, the rotating mechanism includes a geared motor, a rotating plate, and support rods. The geared motor is fixedly installed inside the base and its output end is connected to the center of the lower surface of the rotating plate via a spline. There are four support rods, which are vertically fixedly connected to the upper surface of the rotating plate in a circular array. All four support rods pass through the upper surface of the base and are fixedly connected to the lower surface of the support base.
[0007] Preferably, the adsorption fixing mechanism includes an adsorption plate, an annular adsorption tube, a telescopic tube, and a vacuum adsorption pump. The adsorption plate is fixedly connected to the upper surface of the sliding seat and has a hollow structure inside. The surface of the adsorption plate has an annular groove adapted to the semi-circular ring, and the inner bottom wall of the annular groove has an adsorption hole. The semi-circular ring is disposed in the annular groove. The annular adsorption tube is sleeved on the outside of the adsorption plate, and its suction end is connected to the hollow structure inside the adsorption plate. The telescopic tube is connected to the air outlet end of the annular adsorption tube and passes through the upper surface of the support seat and the base. The vacuum adsorption pump is fixedly installed on the upper surface of the rotating plate, and its suction end is connected to the end of the telescopic tube away from the annular adsorption tube.
[0008] Preferably, the water-cutting mechanism includes a guide rod, an electric push rod, a sliding block, and a water-cutting head. The guide rod is horizontally fixedly connected inside the fixed frame, and the electric push rod is positioned above the guide rod. The fixed end of the electric push rod is horizontally fixedly installed inside the fixed frame, and the sliding block is fixedly connected to the movable end of the electric push rod. The bottom of the sliding block is sleeved on the outside of the guide rod, and the water-cutting head is fixedly installed at its bottom end. The water inlet end of the water-cutting head is connected to an external pipeline through a high-pressure pipeline.
[0009] Preferably, the number of water-cutting mechanisms is three, and the three water-cutting mechanisms are arranged in a circular array within the fixed frame. The angle between the three water-cutting mechanisms is 120°. The sliding blocks in the three water-cutting mechanisms are all inserted through the lower surface of the fixed frame, and the water-cutting blades are all located below the fixed frame.
[0010] Preferably, slide rails are fixedly connected to both sides of the upper surface of the support base, and slide rods are slidably connected inside the slide rails. Two slide rods are fixedly connected to the lower surface of the slide base. A pad is fixedly connected to the middle of the upper surface of the support base, and a groove is opened in the middle of both the pad and the support base. The telescopic tube passes through the inside of the groove. A protective cover is fixedly installed on the top of the base, and the protective cover covers the outside of the adsorption fixing mechanism, the fixing frame and the water cutting mechanism.
[0011] The beneficial effects of the above technical solution are as follows: This semi-circular ring processing cutting device incorporates a rotating mechanism, an adsorption and fixing mechanism, an electric telescopic rod, and a water-cutting mechanism. The adsorption and fixing mechanism firmly holds the semi-circular ring in place, effectively preventing deformation or scratches caused by mechanical clamping tools. The electric telescopic rod adjusts the height of the water-cutting mechanism, allowing it to be positioned appropriately for cutting the semi-circular ring. The water-cutting mechanism uses ultra-high-pressure water jets to radially cut the semi-circular ring. The three water-cutting mechanisms can cut the semi-circular ring into three equal parts. The rotating mechanism can rotate the adsorption and fixing mechanism and the semi-circular ring by 60°, effectively improving positioning accuracy and allowing the water-cutting mechanism to cut the semi-circular ring again, thus precisely dividing the semi-circular ring into six equal parts. During the cutting process, the semi-circular ring parts remain firmly held by the adsorption and fixing mechanism, preventing the semi-circular ring from shaking and affecting the cutting effect, ensuring cutting accuracy, and greatly improving the processing quality of the semi-circular ring.

[0014] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 7 The embodiments are described in detail below.
[0015] This embodiment provides a cutting device for processing semi-circular rings, as shown in the attached figure. Figure 1-7As shown, the structure includes a base 1, a semi-circular ring 2, and a sliding seat 3. The base 1 has a rotating mechanism inside, with a support seat 4 at its top. The rotating mechanism includes a geared motor 8, a rotating plate 9, and support rods 10. The geared motor 8 is fixedly installed inside the base 1, and its output end is connected to the center of the lower surface of the rotating plate 9 via a spline. There are four support rods 10, which are vertically fixed to the upper surface of the rotating plate 9 in a circular array. All four support rods 10 pass through the upper surface of the base 1 and are fixedly connected to the lower surface of the support seat 4. The upper surface of the base 1 has four annular arc-shaped grooves, and the four support rods 10 are vertically inserted into these grooves. The arc-shaped grooves limit and guide the support rods 10. The geared motor 8 drives the rotating plate 9 to rotate, thereby rotating the entire top structure through the support rods 10, facilitating the adjustment of the semi-circular ring 2.
[0016] The sliding seat 3 is slidably connected to the upper surface of the support seat 4. Both sides of the upper surface of the support seat 4 are fixedly connected to the slide rails 19, and the slide rails 19 are slidably connected to the slide rods 20. The two slide rods 20 are fixedly connected to the lower surface of the sliding seat 3. The middle of the upper surface of the support seat 4 is fixedly connected to the pad 21, and the middle of the pad 21 and the support seat 4 are both provided with the slide grooves 22. The telescopic tube 13 passes through the inside of the slide groove 22 and can limit the sliding seat 3. The sliding seat 3 can be pulled outward along the slide rails 19 by the slide rods 20, which makes it convenient for the operator to place the semi-circular ring 2 on the suction plate 11 or to take out the cut semi-circular ring parts. The telescopic tube 13 slides in the slide groove 22, which can prevent the sliding seat 3 from falling off the support seat 4.
[0017] The upper surface of the sliding seat 3 is provided with an adsorption fixing mechanism that can adsorb the semi-circular ring 2. The semi-circular ring 2 is adsorbed on the top of the adsorption fixing mechanism. The adsorption fixing mechanism includes an adsorption disk 11, an annular adsorption tube 12, a telescopic tube 13, and a vacuum adsorption pump 14. The adsorption disk 11 is fixedly connected to the upper surface of the sliding seat 3 and has a hollow structure inside. The surface of the adsorption disk 11 has an annular groove that matches the semi-circular ring 2, and the inner bottom wall of the annular groove has an adsorption hole that communicates with the cavity. The semi-circular ring 2 is placed in the annular groove. The annular adsorption tube 12 is sleeved on the outside of the adsorption disk 11, and the suction end is connected to the adsorption pump 14. The cavity structure inside the auxiliary plate 11 is interconnected. The telescopic tube 13 is connected to the air outlet end of the annular adsorption tube 12 and passes through the upper surface of the support base 4 and the base 1. The vacuum adsorption pump 14 is fixedly installed on the upper surface of the rotating plate 9 and its suction end is connected to the end of the telescopic tube 13 away from the annular adsorption tube 12. The vacuum adsorption pump 14 generates negative pressure in the cavity inside the adsorption plate 11 through the telescopic tube 13 and the annular adsorption tube 12, so that the adsorption hole can firmly suck the semi-circular ring 2 placed in the annular groove. When the semi-circular ring 2 is cut into equal parts, it can still be sucked by the adsorption hole at the bottom, ensuring the stability of the semi-circular ring during cutting.
[0018] A side support plate 5 is fixedly connected to one side of the upper surface of the base 1, and an electric telescopic rod 6 is fixedly installed at the top of the side support plate 5. The movable end of the electric telescopic rod 6 is fixedly connected to a fixed frame 7. There are two electric telescopic rods 6, and the fixed ends of the two electric telescopic rods 6 are vertically fixedly installed on both sides of the upper surface of the side support plate 5. The electric telescopic rod 6 can drive the fixed frame 7 and the water cutting mechanism to move up and down, thereby facilitating the adjustment of the distance between the water cutting mechanism and the semi-circular ring 2, so that the water cutting mechanism can cut the semi-circular ring 2 with the best effect. The fixed frame 7 is equipped with a water cutting mechanism that can move laterally. The water cutting mechanism includes a guide rod 15, an electric push rod 16, a sliding block 17, and a water cutting head 18. The guide rod 15 is horizontally fixedly connected to the inside of the fixed frame 7, and the electric push rod 16 is located above the guide rod 15. The fixed end of the electric push rod 16 is horizontally fixedly installed inside the fixed frame 7, and the sliding block 17 is fixedly connected to the guide rod 15. Connected to the movable end of the electric push rod 16, the bottom of the sliding block 17 is sleeved on the outside of the guide rod 15, and a water-cutting head 18 is fixedly installed at its bottom end. The water inlet end of the water-cutting head 18 is connected to an external pipeline through a high-pressure pipeline. Through the external ultra-high pressure water-cutting equipment, the water-cutting head 18 can cut the semi-circular ring 2 below. The guide rod 15 plays a guiding and supporting role for the sliding block 17. The electric push rod 16 can drive the sliding block 17 and the water-cutting head 18 to move radially along the fixed frame 7, thereby cutting the semi-circular ring 2 radially. There are three water-cutting mechanisms, and the three water-cutting mechanisms are arranged in a ring array in the fixed frame 7. The angle between the three water-cutting mechanisms is 120°. The sliding blocks 17 in the three water-cutting mechanisms are all inserted through the lower surface of the fixed frame 7, and the water-cutting heads 18 are all located below the fixed frame 7. The three water-cutting mechanisms move simultaneously and can cut the semi-circular ring 2 into three equal parts.
[0019] A protective cover 23 is fixedly installed on the top of the base 1, and the protective cover 23 covers the outside of the adsorption fixing mechanism, the fixing frame 7 and the water cutting mechanism. A material discharge port is opened at the bottom of the front of the protective cover 23, and a baffle that can move up and down on the front of the protective cover 23 is provided above the material discharge port. A magnet is fixedly installed on the top of the front of the protective cover 23, and the top of the baffle can be magnetically attracted to the magnet. When the operator needs to place or remove the semi-circular ring 2, the baffle can be lifted up and attracted to the magnet, and then the sliding seat 3 can be pulled outward, so as to facilitate the removal or placement of the semi-circular ring 2. The protective cover 23 can play a protective role and prevent water from splashing out when the water cutting mechanism is running.
[0020] The electric telescopic rod 6, the geared motor 8, the vacuum adsorption pump 14, and the electric push rod 16 are all electrically connected to the external control unit and are all electrically connected to the external circuit through guides.
[0021] In summary, the operating steps of this cutting device for processing semi-circular rings are as follows: 1. Lift the baffle upwards and attach it to the magnet. Then pull the sliding seat 3 outwards and place the concave surface of the semicircular ring 2 into the annular groove on the adsorption plate 11. Then retract the sliding seat 3 so that it is on the same axis as the center of the support seat 4 and the fixing frame 7. 2. Run the vacuum adsorption pump 14 to firmly fix the semi-circular ring 2 onto the adsorption plate 11. Then, adjust the height of the water cutter head 18 by using the electric telescopic rod 6 so that the water outlet end is at a suitable distance from the semi-circular ring 2. 3. The three water cutting heads 18 are operated simultaneously by an external ultra-high pressure water cutting device, and the movable ends of the three electric push rods 16 are also moved synchronously and uniformly, so that the three water cutting heads 18 cut the semi-circular ring 2 radially and equally, thereby forming three identical arc-shaped semi-circular ring structures. 4. Then stop the water cutting mechanism and drive the rotating plate 9 to rotate 60° clockwise via the reduction motor 8, so that the top arc-shaped semi-circular ring structure can rotate 60°, so that the middle part of each arc-shaped semi-circular ring structure can be vertically aligned with the three water cutting heads 18 respectively. Then restart the water cutting head 18 and the electric push rod 16, so that the water cutting head 18 can cut the middle part of the arc-shaped semi-circular ring structure again, thereby cutting the three arc-shaped semi-circular ring structures into 6 equally divided arc-shaped semi-circular rings, thus completing the equal division of the semi-circular rings.
[0022] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
