Description

Technical Field

[0001] The invention belongs to the technical field of burr removal, and in particular relates to a burr removal device. Background Art

[0002] In the field of die-casting production, the traditional operation method of grinding burrs on the surface of die-casting parts with handheld pneumatic files is facing many difficult problems. On the one hand, from the perspective of employee health and working environment, the noise generated during the operation is extremely high. If exposed to it for a long time, the hearing system of employees is easily damaged, causing tinnitus, hearing loss and other problems. In addition, the dust generated by grinding is diffused in the air. These dusts contain metal particles and residual chemicals in the die-casting process. Once inhaled into the lungs of employees, they will induce serious lung diseases such as pneumoconiosis and respiratory infections over time, which will bring a heavy burden to the employees' bodies. At the same time, because manual grinding depends on personal operating experience and skills, the techniques, strengths, and rhythms of different employees vary greatly, which directly leads to extremely poor product consistency and it is difficult to meet the current market demand for high-quality, standardized die-casting products.

[0003] In order to overcome the defects of the above-mentioned grinding methods, a robot grinding method was proposed. The robot grinding method demonstrates the advantages of high automation and precision. Relying on advanced programming technology, it can enable the robot arm to accurately replicate the preset grinding path. Whether it is the grinding angle, strength or speed, it can achieve precise control to ensure the high consistency of product quality. However, this grinding method requires a huge amount of money to be invested in the purchase of the robot body, supporting programming software and a professional maintenance team in the early stage. The cost recovery cycle is long, which is undoubtedly an unbearable burden for most small and medium-sized die-casting companies. Summary of the invention

[0004] The present invention provides a burr removal device, which is used to solve the problem in the prior art that it is impossible to overcome the low efficiency and high safety hazards caused by manual burr removal while taking low cost into account.

[0013] Optionally, the burr removal device further includes a slide cylinder, a cylinder body of the slide cylinder is fixed on the first movable shaft, and the second grinding unit is arranged on the slide of the slide cylinder.

[0014] Optionally, the burr removal device also includes a linear slide rail, the first movable axis is slidably connected to the linear slide rail, the linear slide rail is parallel to the second movable axis, and the linear slide rail spans between the fourth movable axis and the fifth movable axis along the axial direction of the second movable axis.

[0015] Optionally, the burr removal device further includes a vacuum suction cup, which is disposed in the workpiece fixing unit to adsorb the workpiece on the workpiece fixing unit.

[0016] Optionally, the burr removal device further includes a shell having an inner cavity, the first grinding unit, the second grinding unit and the moving unit are all located in the inner cavity, and the moving stroke of the first moving axis can extend to outside the inner cavity.

[0017] Optionally, a surface area of ​​a side of the grinding head of the second grinding unit close to the workpiece fixing unit is larger than a surface area of ​​a side of the grinding head of the first grinding unit close to the workpiece fixing unit.

[0018] Optionally, the grinding heads of the first grinding unit and the second grinding unit are both cylindrical, and in the axial direction of the first movable axis, the length of the grinding head of the first grinding unit is greater than the length of the grinding head of the second grinding unit.

Since the grinding sides of the first grinding unit and the second grinding unit can be arranged opposite to the workpiece fixing unit after movement so that the grinding sides can grind the workpiece, it can be ensured that the first grinding unit and the second grinding unit can grind the burrs of the workpiece fixed on the workpiece fixing unit.

[0021] Therefore, in summary, the present invention can ultimately realize the automatic grinding of burrs on the workpiece, and because the present invention utilizes three movable axes and two grinding units to grind the burrs, the surroundings and top of the burrs can also be polished, ensuring a certain grinding accuracy and avoiding the high cost problem of using robots for grinding in the prior art. Therefore, the present invention can ultimately solve the problem in the prior art that it is impossible to overcome the low efficiency and high safety hazards brought about by manual burr removal while taking into account low cost.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] In order to make the description of the disclosed content more detailed and complete, the following is an illustrative description of the implementation methods and specific examples of the present invention; however, this is not the only form of implementing or using the specific embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0032] In addition, in the description of the embodiments of the present invention, "multiple" means two or more than two, and other quantifiers are similar and should be understood. The preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In addition, the embodiments of the present invention and the features therein may be combined with each other without conflict.

[0033] like Figure 1 and Figure 2 The figure shows a three-dimensional structure diagram of a burr removal device provided by an embodiment of the present invention in different directions. Figure 3-Figure 5 The burr removal device provided by the embodiment of the present invention is an internal structure diagram in different directions. The burr removal device includes a workpiece fixing unit 100 , a first grinding unit 210 , a second grinding unit 220 and a moving unit 300 .

[0034] The workpiece fixing unit 100 is used to fix the workpiece 400 and can be any unit structure that can fix the workpiece 400. For example, it can be a clamping structure that matches the shape of the workpiece 400, so that the workpiece 400 can be clamped and fixed. Since the embodiment of the present invention is to remove burrs from the workpiece 400, the workpiece 400 mentioned in the embodiment of the present invention is a workpiece 400 with burrs.

[0035] The first grinding unit 210 is used to grind the burrs around the workpiece 400, and the second grinding unit 220 is used to grind the burrs on the top of the workpiece 400. The first grinding unit 210 and the second grinding unit 220 can be any unit structure that can grind the burrs of the workpiece 400, and are not limited in detail here.

[0036] The moving unit 300 includes a first moving axis 310, a second moving axis 320 and a third moving axis 330, and the first moving axis 310, the second moving axis 320 and the third moving axis 330 are perpendicular to each other. It can be understood that since the first moving axis 310, the second moving axis 320 and the third moving axis 330 are perpendicular to each other, the first moving axis 310, the second moving axis 320 and the third moving axis 330 can constitute a three-dimensional space, and here only requires the first moving axis 310, the second moving axis 320 and the third moving axis 330 to be perpendicular to each other, and does not specifically require the directions of the first moving axis 310, the second moving axis 320 and the third moving axis 330. For example, the first moving axis 310 can be in the Z-axis direction, the second moving axis 320 can be in the Y-axis direction, and the third moving axis 330 can be in the X-axis direction. The first movable shaft 310, the second movable shaft 320 and the third movable shaft 330 can move in their respective axial directions. The first movable shaft 310, the second movable shaft 320 and the third movable shaft 330 can move in their respective axial directions in any manner that can be realized. For example, the first movable shaft 310, the second movable shaft 320 and the third movable shaft 330 can all be provided with servo modules to output power through the servo modules so that the first movable shaft 310, the second movable shaft 320 and the third movable shaft 330 can move in their respective axial directions. Since the burr removal equipment involves related electrical circuits, a dust-free drag chain 340 can be provided on the side of the first movable shaft 310, the second movable shaft 320 and the third movable shaft 330 to protect and guide cables, air pipes and other pipelines.

[0037] The first grinding unit 210 and the second grinding unit 220 are arranged on the first movable shaft 310, so that the first grinding unit 210 and the second grinding unit 220 can move along the axial direction of the second movable shaft 320 and the third movable shaft 330 respectively. It can be understood that when the first grinding unit 210 and the second grinding unit 220 are both arranged on the first movable shaft 310, the method of enabling both to move along the axial direction of the second movable shaft 320 and the third movable shaft 330 can be any achievable method, for example, the first movable shaft 310 can be arranged on the second movable shaft 320, and the second movable shaft 320 can be arranged on the third movable shaft 330. Since the second movable shaft 320 and the third movable shaft 330 can move in their respective axial directions, the first movable shaft 310 can finally be When the second movable shaft 320 and the third movable shaft 330 move in the axial direction, the first grinding unit 210 and the second grinding unit 220 on the first movable shaft 310 can naturally also move in the axial direction of the second movable shaft 320 and the third movable shaft 330. Similarly, the first movable shaft 310 can be set on the third movable shaft 330, and the third movable shaft 330 can be set on the second movable shaft 320, so that the first grinding unit 210 and the second grinding unit 220 can also move in the axial direction of the second movable shaft 320 and the third movable shaft 330.

[0038] The grinding sides of the first grinding unit 210 and the second grinding unit 220 can be disposed opposite to the workpiece fixing unit 100 after being moved, so that the grinding sides can grind the workpiece 400 . Specifically, it has been mentioned above that the first grinding unit 210 and the second grinding unit 220 are both arranged on the first movable axis 310, so that the first grinding unit 210 and the second grinding unit 220 can both move in the axial direction of the second movable axis 320 and the third movable axis 330, and it is also mentioned above that the first movable axis 310 can move in its own axial direction, so finally the first grinding unit 210 and the second grinding unit 220 can move in three axial directions of the first movable axis 310, the second movable axis 320 and the third movable axis 330, and since the first movable axis 310, the second movable axis 320 and the third movable axis 330 are perpendicular to each other, the first grinding unit 210 and the second grinding unit 220 can move in the three-dimensional stroke formed by the above three movable axes, so as long as the workpiece fixing unit 100 can appear in the three-dimensional stroke of the three movable axes, it can be ensured that the first grinding unit 210 and the second grinding unit 220 can grind the burrs of the workpiece 400 fixed on the workpiece fixing unit 100. Furthermore, in order to ensure that the first grinding unit 210 and the second grinding unit 220 can grind the burrs of the workpiece 400 , it is necessary to arrange the grinding sides of the first grinding unit 210 and the second grinding unit 220 opposite to the workpiece 400 .

[0039] In an optional implementation, Figure 3-Figure 5 As shown, the first movable shaft 310 is arranged on the second movable shaft 320, and the first movable shaft 310 can move along the axial direction of the second movable shaft 320. It can be understood that, since it has been mentioned above that the second movable shaft 320 can move along its own axial direction, when the first movable shaft 310 is arranged on the second movable shaft 320, the first movable shaft 310 can naturally move along the axial direction of the second movable shaft 320 with the second movable shaft 320.

[0040] Further, the workpiece fixing unit 100 is disposed on the third movable shaft 330, and the workpiece fixing unit 100 can move in the axial direction of the third movable shaft 330. It can be understood that, as mentioned above, the first grinding unit 210 and the second grinding unit 220 are disposed opposite to the workpiece fixing unit 100, when the workpiece fixing unit 100 moves in the axial direction of the third movable shaft 330, the first grinding unit 210 and the second grinding unit 220 also move in the axial direction of the third movable shaft 330 relative to the third movable shaft 330. Therefore, in this implementation, the first grinding unit 210 and the second grinding unit 220 can realize axial movement of the first movable shaft 310, the second movable shaft 320 and the third movable shaft 330. Furthermore, since the workpiece fixing unit 100 can move in the axial direction of the third movable axis 330, when the workpiece 400 needs to be placed on the workpiece fixing unit 100 so that the first grinding unit 210 and the second grinding unit 220 can grind the workpiece 400, the initial position of the workpiece fixing unit 100 does not necessarily have to be at a position directly opposite to the first grinding unit 210 and the second grinding unit 220. Instead, the workpiece fixing unit 100 can be set at a position on the third movable axis 330 that is farther away from the first grinding unit 210 and the second grinding unit 220, thereby avoiding the problem that the operator or the robot arm is damaged when placing the workpiece 400 due to being close to the first grinding unit 210 and the second grinding unit 220.

[0041] To sum up, in the present implementation, while ensuring that the first grinding unit 210 and the second grinding unit 220 can move in the axial direction of the three movable axes, thereby ensuring that the workpiece 400 in any three-dimensional travel space can be ground, and ensuring that the workpiece 400 is ground in all directions, it can also avoid the problem of the operator or the robot arm being damaged when placing the workpiece 400 due to the close distance to the first grinding unit 210 and the second grinding unit 220.

[0042] In an optional implementation, Figure 6Another internal structure diagram of the burr removal device provided by an embodiment of the present invention is shown. The burr removal device may also include a shavings collection hopper 510. The inlet of the shavings collection hopper 510 is arranged within the moving stroke of the workpiece fixing unit 100 to collect the waste after grinding the workpiece 400. In order to better collect the waste, the outlet area of ​​the shavings collection hopper 510 may be larger than the inlet area, and a waste collection box 520 may be arranged near the outlet side of the shavings collection hopper 510, so that the waste in the waste collection box 520 can be poured out after the waste is full. Furthermore, since there are electrical devices in the burr removal device, in order to prevent the raised waste from damaging the electrical devices, a baffle 530 may be arranged on one side near the outer side of the waste collection box 520 to block the raised waste from the waste collection box 520.

[0043] In an optional implementation, Figure 1 and Figure 2 As shown, the burr removal device may also include a control key 610 and a touch screen 620 for controlling the device. The circuit and structure of controlling the operating state of the device using the control key 610 and the touch screen 620 are relatively mature technologies in the relevant field and are not limited in detail here.

[0044] In an optional implementation, Figure 3-Figure 5 As shown, the third movable axis 330 includes a fourth movable axis 331 and a fifth movable axis 332, and a workpiece fixing unit 100 is provided on the fourth movable axis 331 and the fifth movable axis 332. The fourth movable axis 331 and the fifth movable axis 332 are respectively perpendicular to the first movable axis 310 and the second movable axis 320, and the second movable axis 320 spans between the fourth movable axis 331 and the fifth movable axis 332 along its own axial direction.

[0045] It can be understood that, since the second movable shaft 320 spans between the fourth movable shaft 331 and the fifth movable shaft 332 along its own axial direction, and the first grinding unit 210 and the second grinding unit 220 are arranged on the second movable shaft 320 along with the first movable shaft 310, the first grinding unit 210 and the second grinding unit 220 can move between the fourth movable shaft 331 and the fifth movable shaft 332 along with the first movable shaft 310. Since the workpiece fixing unit 100 is arranged on both the fourth movable shaft 331 and the fifth movable shaft 332, the first grinding unit 210 and the second grinding unit 220 can move between the fourth movable shaft 331 and the fifth movable shaft 332 along with the first movable shaft 310. When the second grinding unit 220 is grinding the workpiece 400 on the fourth movable axis 331 or the fifth movable axis 332, the workpiece fixing unit 100 of the other movable axis of the fourth movable axis 331 and the fifth movable axis 332 can be loaded (i.e., the workpiece 400 is placed). In this way, after the first grinding unit 210 and the second grinding unit 220 finish grinding one workpiece 400, the workpiece 400 on the other movable axis can be polished immediately without waiting for the loading of the movable axis to be completed before grinding, thereby effectively improving the grinding efficiency of the workpiece 400.

[0046] In an optional implementation, Figure 3-Figure 5 As shown, the first grinding unit 210 is fixed on the first moving shaft 310 , and the second grinding unit 220 is movably disposed on the first moving shaft 310 , so that the second grinding unit 220 can move on the first moving shaft 310 along the axial direction of the first moving shaft 310 .

[0047] Specifically, the second grinding unit 220 can be movably arranged on the first movable shaft 310, so that the second grinding unit 220 can move on the first movable shaft 310 along the axial direction of the first movable shaft 310 in any feasible manner. For example, a linear guide rail can be arranged on the first movable shaft 310 along the axial direction of the first movable shaft 310, and a guide block adapted to the linear guide rail can be arranged on the second grinding unit 220, and a traction device can be arranged for pulling the guide block, and the traction device can be a rope pulley, etc.

[0048] It can be understood that the first grinding unit 210 is fixed on the first movable shaft 310, and it has been stated above that the first movable shaft 310 can move in the axial direction of the second movable shaft 320 and the third movable shaft 330, and can move along the axial direction of the first movable shaft 310. Therefore, the first grinding unit 210 can move in the axial direction of the first movable shaft 310, the second movable shaft 320 and the third movable shaft 330, and naturally it can grind any position of the workpiece 400, including the surrounding position of the workpiece 400, and the second grinding unit 220 is a grinding unit for the workpiece 400. 0 is ground, since the surrounding positions and the top position of the workpiece 400 are at different positions in the axial direction of the first movable axis 310, it is necessary to make the second grinding unit 220 and the first grinding unit 210 at different positions in the axial direction of the first movable axis 310. To this end, by enabling the second grinding unit 220 to move axially along the first movable axis 310 on the first movable axis 310, it can be achieved that the first grinding unit 210 is grinding the surroundings of the workpiece 400 while the second grinding unit 220 is grinding the top of the workpiece 400.

[0049] It should be noted that the top of the workpiece 400 in the embodiment of the present invention refers to the position of the workpiece 400 excluding the surroundings of the workpiece 400 , and does not specify a certain surface.

[0050] In an optional implementation, Figure 4 As shown, the burr removal device further includes a slide cylinder 700, a cylinder body 710 of the slide cylinder 700 is fixed on the first moving shaft 310, and the second grinding unit 220 is arranged on the slide 720 of the slide cylinder 700. It can be understood that the movement of the second grinding unit 200 on the first moving shaft 310 can be realized by using the slide cylinder 700.

[0051] In an optional implementation, Figure 4 As shown, the burr removal device also includes a linear slide rail 800, the first movable axis 310 is slidably connected to the linear slide rail 800, the linear slide rail 800 is parallel to the second movable axis 320, and the linear slide rail 800 spans between the fourth movable axis 331 and the fifth movable axis 332 along the axial direction of the second movable axis 320.

[0052] Specifically, the way in which the first movable shaft 310 is slidably connected to the linear slide rail 800 can be any feasible way. For example, a movable block can be set on the first movable shaft 310, and the movable block can be provided with a slideway matching the linear slide rail 800. The linear slide rail 800 can be further set in the slideway, so that when the first movable shaft 310 moves along the axial direction of the first movable shaft 310, the first movable shaft 310 can move synchronously on the linear slide rail 800.

[0053] It can be understood that since the first movable shaft 310 needs to drive the first grinding unit 210 and the second grinding unit 220 when moving in the axial direction of the second movable shaft 320, the first movable shaft 310 has a large deadweight. In this implementation, the first movable shaft 310 is slidably connected to the linear slide rail 800, and the linear slide rail 800 can be used to bear the deadweight of the first movable shaft 310, thereby making the movement of the first movable shaft 310 more stable.

[0054] In an optional implementation, Figure 7 The figure shows an exploded view of the workpiece fixing unit provided in an embodiment of the present invention. The burr removal device further includes a vacuum suction cup 110 . The vacuum suction cup 110 is arranged in the workpiece fixing unit 100 to adsorb the workpiece 400 on the workpiece fixing unit 100 .

[0055] It can be understood that using the vacuum suction cup 110 to suck the workpiece 400 makes it easier to disassemble the workpiece.

[0056] In an optional implementation, Figure 1 and Figure 2 As shown, the burr removal device further includes a housing 900 having an inner cavity, wherein the first grinding unit 210, the second grinding unit 220 and the moving unit 300 are all located in the inner cavity, and the moving stroke of the third moving axis 330 can extend to outside the inner cavity.

[0057] It is understandable that the first grinding unit 210, the second grinding unit 220 and the moving unit 300 are all arranged in the inner cavity formed by the housing 900, so that the waste materials formed by the grinding of the first grinding unit 210 and the second grinding unit 220 when grinding the burrs of the workpiece 400 can be prevented from scattering everywhere, causing adverse effects on the operator and the machine. Furthermore, the moving stroke of the third moving axis 330 can extend outside the inner cavity, which means that the workpiece fixing unit 100 of the third moving axis 330 can extend outside the inner cavity. Therefore, when the workpiece 400 is fixed to the workpiece fixing unit 100 by an operator or a robot arm, the operator can be prevented from inhaling waste materials that affect health, and the operator or the robot arm can be prevented from being injured by the grinding equipment.

[0058] In an optional implementation, Figure 8The figure shows a three-dimensional structural diagram of another burr removal device provided by an embodiment of the present invention. A dust outlet 910 can be provided on the housing 900, and the dust outlet 910 can be connected to a dust suction pipe to absorb waste materials during the grinding process. An alarm light 920 can also be provided on the outer wall of the housing 900 for alarm. Casters 930 can also be provided at the bottom of the burr removal device to facilitate the movement of the device, and a foot cup 940 can also be provided at the bottom of the burr removal device so that the device can stand firmly on the ground.

[0059] In an optional implementation, Figure 3 and Figure 4 As shown, the surface area of ​​the second grinding head 221 of the second grinding unit 220 close to the workpiece fixing unit 100 is greater than the surface area of ​​the first grinding head 211 of the first grinding unit 210 close to the workpiece fixing unit 100 .

[0060] It can be understood that since the second grinding unit 220 is used to grind the top of the workpiece 400 and the first grinding unit 210 is used to grind the four sides of the workpiece 400, the first grinding unit 210 uses the side wall of the grinding head for grinding, while the second grinding unit 220 uses the grinding head to grind on the side close to the workpiece fixing unit 100. Therefore, the grinding head of the second unit is set to be larger. On the one hand, it can ensure that more top positions can be polished. On the other hand, since the grinding head uses the side close to the workpiece fixing unit 100 to directly contact the part that needs to be polished, the larger area can ensure that the side of the grinding head close to the workpiece fixing unit 100 will not be damaged.

[0061] In an optional implementation, Figure 3 and Figure 4 As shown, the grinding heads of the first grinding unit 210 and the second grinding unit 220 are both cylindrical, and in the axial direction of the first moving axis 310 , the length of the first grinding head 211 of the first grinding unit 210 is greater than the length of the second grinding head 221 of the second grinding unit 220 .

[0062] It can be understood that since the first grinding unit 210 is used to grind the four sides of the workpiece 400, the length of the grinding head of the first grinding unit 210 in the axial direction of the first movable axis 310 is set to be larger, so that the side area of ​​the first grinding unit 210 can be larger, thereby ensuring that more positions around the workpiece 400 can be grinded on the one hand, and on the other hand, since the grinding head uses the side close to the workpiece fixing unit 100 to directly contact the part to be polished, the larger area can ensure that the side of the grinding head close to the workpiece fixing unit 100 will not be damaged.

[0063] Optionally, the burr removal device provided in the embodiment of the present invention may further include a bracket 1000 for supporting other structures in the burr removal device.
