Description

Technical Field

[0001] The utility model relates to the technical field of deburring, in particular to a deburring tool based on a rotating workpiece. Background Art

[0002] Most mainstream motors on the market are made of metal, but some motor shells are made of plastic, which are usually made directly from molds. During the manufacturing process, the finished product is not ready for use. There are more or less uneven spots or burrs on the plastic shell. If they are not processed when entering the next step of assembling the rotor and stator, errors are likely to occur during the assembly process, affecting the precision and quality of the finished product. The burrs will also damage the aesthetics of the product. If the burrs on the plastic are not completely processed without polishing or insufficient polishing, the circulation and sales level of the plastic will be greatly reduced.

[0003] Currently, the main method of deburring is manual scraping. The reason is that the automated deburring process is complicated, and the cost of programming and equipment design and manufacturing is high. In addition, there are not many devices that can fully automate deburring, and there are even fewer automated deburring devices that can be specifically adapted to small workpieces such as motor housings. In the process of manual scraping of burrs, there is almost no workpiece loss, and only some cheap deburring knives are consumed daily, which is relatively low in cost.

[0004] However, manual burr removal also increases the labor intensity of workers and is not efficient. For plastic workpieces, many workpieces have sprues and burrs that are difficult to remove manually, which has a greater impact on subsequent assembly. To this end, the present application proposes a deburring tool based on a rotating workpiece. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a deburring tool based on a rotating workpiece, which solves the problem that it is difficult to manually remove sprues and burrs inside the workpiece.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a deburring tool based on a rotating workpiece, comprising a blade body and a tool handle, wherein the blade body is fixedly connected to one end of the tool handle, the blade body has an inclined blade, and the blade and its two adjacent sides are provided with rounded corners, the tool handle comprises a handle rod and a pressure block, the handle rod is provided with a groove for accommodating the blade, and the pressure block is fixed to the handle rod by screws.

[0007] Preferably, the two sides adjacent to the blade are arranged in parallel, and the angle between the blade and one of the adjacent sides is 45-75°.

[0008] Preferably, the blade body is flat.

[0009] Preferably, the radius of the fillet is about 0.2-2 mm.

[0010] Preferably, one end of the handle rod away from the groove is also rotatably connected to the knife shaft.

[0011] Preferably, the rotation angle of the handle rod on the knife shaft is ±10°.

[0012] Compared with the prior art, the utility model provides a deburring tool based on a rotating workpiece, which has the following beneficial effects:

[0013] The deburring tool based on the rotating workpiece adopts an inclined blade to enable the blade body to have a longer processable width, which is more in line with the rapid processing requirements of deburring, and also enables the cutter shaft to contact the processing surface of the rotating workpiece in an inclined posture. Compared with a deburring tool in which the blade is perpendicular to the cutter shaft, it can better reach into the interior of the workpiece to process the inner wall of the rotating workpiece, and is very suitable for deburring processing of many injection molded workpieces.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] See also Figure 1-2 The utility model provides the following technical solution: a deburring knife comprises a blade body, wherein the blade body has an inclined blade, and the blade and its adjacent two sides are provided with rounded corners.

[0023] As an optional implementation scheme of the utility model, the use of an inclined blade allows the blade body to have a longer processable width, which is more in line with the rapid processing requirements of deburring, and also allows the cutter shaft to contact the processing surface of the rotating workpiece in an inclined posture. Compared with a deburring knife in which the blade is perpendicular to the cutter shaft, it can better reach into the interior of the workpiece to process the inner wall of the rotating workpiece, which is very suitable for deburring processing of many injection molded workpieces.

[0024] like Figure 1-3 As shown, the two sides adjacent to the blade are arranged in parallel, the angle between the blade and one of the adjacent sides is 45-75°, the angle between the blade and one of the adjacent sides is 60°, the blade body is flat, and the width of the two sides adjacent to the blade is The radius of the fillet is about 0.2-2 .

[0025] As an optional implementation scheme of the utility model, the above-mentioned blade body is used to form a deburring tool suitable for cylindrical plastic motor housings with relatively small specifications and volumes, and can process both the surface and the interior of such workpieces. The deburring tool can also be directly installed on a robot arm to scrape and smooth the surface of the workpiece.

[0026] Embodiment 2:

[0027] like Figure 4-5 As shown, the utility model also provides the following technical solutions:

[0028] The deburring tool based on the rotating workpiece also includes a tool handle, which includes a handle rod and a pressure block. The handle rod is provided with a groove for accommodating a blade, and the pressure block is fixed to the handle rod by screws.

[0029] As an optional implementation scheme of the utility model, it is possible to replace the blade body without completely removing the screws. When the screws are tightened, the pressure block can press the blade body into the groove, which is very convenient to operate.

[0030] like Figure 4-5 As shown, one end of the handle rod away from the groove is also rotatably connected to the knife shaft, and the rotation angle of the handle rod on the knife shaft is ±10°.

[0031] As an optional implementation scheme of the utility model, when the processing surface of the rotating workpiece contacts the blade, if the blade body is subject to greater resistance due to excessive surface undulations of the workpiece, the blade body can rotate on the blade shaft to form an avoidance. In this way, the feed of the blade is reduced. At the same time, the rounded corners on the blade body prevent the workpiece from being scratched, thereby achieving flexible processing, ensuring that the wear on the blade is reduced without affecting the deburring effect of the workpiece, and extending the service life of the deburring knife.

[0032] In the technical solution, the rotation angle of the handle rod on the tool shaft is ±3°, which is more suitable for floating processing of products such as motor housings.

[0033] The working principle and use process of the utility model are as follows: put the blade into the groove and tighten the screws to complete the installation of the blade body. When deburring, the mechanical claw on the robot arm grabs the workpiece and rotates the workpiece. The rotating workpiece is brought to the vicinity of the blade by the robot arm, and the processing surface of the workpiece is parallel to the blade. Then the workpiece is close to the blade to start the deburring process. When the blade is subject to greater resistance, the tool handle rotates on the tool shaft to reduce the feed and realize flexible processing.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
