Description

Technical Field

[0001] This invention relates to the field of burr removal devices, and more particularly to a cutting burr removal device. Background Technology

[0002] Fan dynamic balancing is an essential production process in the fan industry. When a fan is running at high speed, it will rotate with an "uneven weight" and cause unbalanced vibration, which will greatly affect the service life of the product. In the process of dynamic balancing the rotor, it is necessary to use a milling cutter to cut away the weight to achieve the purpose of dynamic balance.

[0003] A fan blade balancing cutting machine, disclosed in CN105345113B, includes a machine body, a cutting tool, a central positioning mechanism, a balancing detection machine, and a clamping cylinder. The cutting tool is mounted at the center of the top of the machine body. The central positioning mechanism and the balancing detection machine are both located on the front side of the top of the machine body. An X-axis moving module symmetrical to the central positioning mechanism is fixedly mounted on the rear side of the top of the machine body. A Y-axis moving module is slidably mounted between the two X-axis moving modules. A Z-axis moving module is movably mounted on the Y-axis moving module. Clamping cylinders and second position sensors are movably mounted on the X-axis, Y-axis, and Z-axis moving modules. This invention uses multi-axis motion and a cutting tool to precisely cut the unbalanced points of the fan, reducing the weight of the magnetic ring on the inner wall of the fan blade. The cut magnetic ring surface is smooth, the cutting is accurate, and the cutting speed is fast, solving the problems of vibration and short service life caused by fan rotation imbalance.

[0004] However, during the cutting process, burrs are easily generated at the cutting marks due to tool wear or rotor material. Especially when the cutting material is plastic, the heat generated during the cutting process will melt the cut plastic shavings and stick them to the rotor cutting marks, affecting the subsequent processes of the rotor. Therefore, it is necessary to remove them. In actual production, someone needs to manually scrape off the burrs of each product, which is time-consuming and labor-intensive. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a cutting burr removal device, comprising: a supporting main frame, on which the rotor workpiece is placed with its two ends supported;

[0006] A deburring structure is installed inside the support frame. The deburring structure removes burrs from the rotor workpiece by driving an end grinding wheel.

[0007] A drive structure is installed on the supporting main frame. The drive structure drives the deburring structure to move by extending and retracting a telescopic rod.

[0008] A sliding structure is provided between the supporting main frame and the deburring structure to facilitate the movement of the deburring structure inside the supporting main frame;

[0009] A limiting structure is installed on the deburring structure, which allows the deburring structure to adapt to rotor workpieces with different cutting amounts.

[0010] As a further description of the above technical solution: the deburring structure includes a connecting frame, a grinding head and a louvered grinding wheel. The connecting frame is connected to a sliding structure at its lower part. The grinding head is disposed inside the connecting frame. One end of the grinding head is connected to the louvered grinding wheel, and the other end of the grinding head is connected to a rotating bearing.

[0011] As a further description of the above technical solution: the driving structure includes a driving cylinder, a fixed plate and a connecting plate. The driving cylinder is connected to one end of the connecting plate, the other end of the connecting plate is connected to the connecting frame, and the fixed plate is connected between the driving cylinder and the connecting frame.

[0012] As a further description of the above technical solution: the sliding structure includes a sliding plate and a slider, the sliding plate is fixed on the supporting main frame, and the slider is slidably connected to the sliding plate through an internal groove.

[0013] As a further description of the above technical solution: the limiting structure includes a mounting frame, a spring, a limiting block and a fixing bolt. The mounting frame is fixed to the connecting frame by the fixing bolt. One end of the spring is connected and fixed inside the mounting frame, and the other end of the spring is connected to the limiting block. The limiting block passes through the connecting frame and is connected to the grinding head.

[0014] As a further description of the above technical solution: two sliding structures are provided, and the sliding structures are connected between the connecting frame and the supporting main frame.

[0015] As a further description of the above technical solution: the grinding head is a right-angle grinding head.

[0016] As a further description of the above technical solution: the surface of the connecting frame is provided with bolt holes, the bolt holes are adapted to the fixing bolts, and multiple bolt holes are provided.

[0017] As a further description of the above technical solution: a limiting groove is formed on the surface of the connecting frame, and the grinding head is connected to the limiting block through the limiting groove.

[0018] As a further description of the above technical solution: the upper part of the slider is connected to the connecting frame, and the sliding plate is adapted to the slider.

[0019] The above technical solution has the following advantages or beneficial effects:

[0020] 1. This invention installs a louvered grinding wheel on a right-angle grinding head, which is mounted on a rotating bearing. When deburring is required, the grinding head is pushed into the rotor workpiece by the drive cylinder. The rotating bearing drives the louvered grinding wheel to quickly grind the product surface, thus automating deburring and saving time and effort.

[0021] 2. This invention features a driving structure and a limiting structure. The driving cylinder can move the connecting frame back and forth, which in turn moves the louvered grinding wheel to the rotor workpiece to remove burrs. When the louvered grinding wheel just contacts the rotor workpiece, the rotor workpiece will squeeze the louvered grinding wheel, causing the louvered grinding wheel and the grinding head to rotate and finely adjust in the limiting groove under the action of spring contraction. Then, the louvered grinding wheel enters the side of the rotor workpiece. At this time, the louvered grinding wheel is lightly pressed onto the product by the spring rebound. Therefore, within the normal range, it can automatically adapt regardless of the cutting amount.

[0022] 3. By providing multiple bolt holes, the mounting frame can be fixed in the bolt holes at different positions by fixing bolts, so that the spring force and rotation angle can be adjusted within a certain range. Attached Figure Description

[0034] Example 1:

[0035] like Figure 1 As shown, the present invention provides a burr removal device, comprising a support frame 1 on which a rotor workpiece 6 is supported at both ends; a deburring structure 2 installed inside the support frame 1, which removes burrs from the rotor workpiece 6 via a driven end grinding wheel; a drive structure 3 installed on the support frame 1, which moves the deburring structure 2 via a telescopic rod; and a sliding structure 4 disposed between the support frame 1 and the deburring structure 2 to facilitate the movement of the deburring structure 2 within the support frame. The frame 1 moves inside; the limiting structure 5 is installed on the deburring structure 2, and the limiting structure 5 allows the deburring structure 2 to adapt to rotor workpieces 6 with different cutting amounts; a high-speed rotating micro louvered grinding wheel 203 is used to grind the burr parts of the product. The louvered grinding wheel 203 is installed on the right-angle grinding head 202. When the product is being cut, the louvered grinding wheel 203 will be pushed out of the working area by the drive structure 3. After the cutting is completed, the milling cutter moves to one side, and the louvered grinding wheel 203 quickly enters the grinding and exits. The whole working process takes less than 1 second.

[0036] like Figure 1As shown, the drive structure 3 includes a drive cylinder 31, a fixed plate 32, and a connecting plate 33. The drive cylinder 31 is connected to one end of the connecting plate 33, and the other end of the connecting plate 33 is connected to the connecting frame 201. The fixed plate 32 is connected between the drive cylinder 31 and the connecting frame 201. The sliding structure 4 includes a slide plate 41 and a slider 42. The slide plate 41 is fixed on the supporting main frame 1, and the slider 42 is slidably connected to the slide plate 41 through an internal groove. The top of the slider 42 is connected to the connecting frame 201, and the slide plate 41 and the slider 42 are adapted to each other. The deburring structure 2 can be moved back and forth by the connecting plate 33 of the drive cylinder 31, and the slider 42 slides on the slide plate 41, which facilitates the entry and exit of the deburring structure 2.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the deburring structure 2 includes a connecting frame 201, a grinding head 202, and a louvered grinding wheel 203. The connecting frame 201 is connected to the sliding structure 4 below. The grinding head 202 is disposed inside the connecting frame 201. One end of the grinding head 202 is connected to the louvered grinding wheel 203, and the other end of the grinding head 202 is connected to the rotating bearing 204. By mounting the louvered grinding wheel 203 on the right-angle grinding head 202 and the grinding head 202 on the rotating bearing 204, when deburring is required, the grinding head 202 will be pushed into the rotor workpiece 6 by the drive cylinder 31. The rotating bearing 204 drives the louvered grinding wheel 203 to quickly grind the product surface, thus automating deburring and saving time and effort.

[0038] Example 2:

[0039] like Figure 2 As shown, based on Embodiment 1, the present invention provides a technical solution: two sliding structures 4 are provided, the sliding structures 4 are connected between the connecting frame 201 and the supporting main frame 1, the grinding head 202 is a right-angle grinding head, the connecting frame 201 has bolt holes 205 on its surface, the bolt holes 205 are adapted to the fixing bolts 54, and multiple bolt holes 205 are provided. The connecting frame 201 has a limiting groove 206 on its surface, and the grinding head 202 is connected to the limiting block 53 through the limiting groove 206. By providing multiple bolt holes 205, the mounting frame 51 can be fixed in the bolt holes 205 at different positions by the fixing bolts 54, so that the spring force and rotation angle can be adjusted within a certain range.

[0040] like Figure 1 and Figure 2As shown, in this embodiment, the limiting structure 5 includes a mounting frame 51, a spring 52, a limiting block 53, and a fixing bolt 54. The mounting frame 51 is fixed to the connecting frame 201 by the fixing bolt 54. One end of the spring 52 is connected and fixed inside the mounting frame 51, and the other end of the spring 52 is connected to the limiting block 53. The limiting block 53 passes through the connecting frame 201 and is connected to the grinding head 202. The connecting frame 201 can be moved back and forth by the driving cylinder 31, and the connecting frame 201 will drive the louvered grinding wheel 203 to move to the rotor. The position of part 6 is used to remove burrs from rotor workpiece 6. When the louvered grinding wheel 203 just contacts the rotor workpiece 6, the rotor workpiece 6 will squeeze the louvered grinding wheel 203, so that the louvered grinding wheel 203 and the grinding head 202 rotate and finely adjust in the limiting groove 206 under the action of the spring 52. Then the louvered grinding wheel 203 enters the side of the rotor workpiece 6. At this time, the louvered grinding wheel 203 is lightly pressed on the product by the action of the spring rebound. Therefore, within the normal range, it can automatically adapt regardless of the cutting amount.

[0041] Working principle: The operator first places the product on the rotor workpiece 6 for cutting. After cutting, the grinding head 202 is pushed into the rotor workpiece 6 by the drive cylinder 31. The rotating bearing 204 drives the louvered grinding wheel 203 to quickly grind the product surface, automatically deburring and saving time and effort. The drive cylinder 31 can drive the connecting frame 201 to move back and forth. The connecting frame 201 will drive the louvered grinding wheel 203 to the position of the rotor workpiece 6 to remove burrs. When the louvered grinding wheel 203 just contacts the rotor workpiece 6, the rotor workpiece 6 will squeeze the louvered grinding wheel 203. Under the action of the spring 52, the louvered grinding wheel 203 and the grinding head 202 rotate and finely adjust in the limiting groove 206. Then the louvered grinding wheel 203 enters the side of the rotor workpiece 6. At this time, under the action of the spring rebound, the louvered grinding wheel 203 is lightly pressed on the product. Therefore, within the normal range, it can automatically adapt to the size of the cutting.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
