Description

Technical Field

[0001] This invention relates to the field of irregular thin-walled shell processing technology, specifically a deburring device for processing irregular thin-walled shells. Background Technology

[0002] Irregularly shaped shells are shells that differ from existing products in appearance and have a certain irregular shape. They can be used on the outer shell of some products or the outer shell of mechanical structures. Irregularly shaped shells have a unique appearance to meet production needs.

[0003] After rough machining, irregularly shaped thin-walled shells inevitably have some burrs on their outer surface and inner wall. Failure to treat these burrs may affect the quality of the shell and subsequent production. Due to the shape of the irregular shell, the existing deburring methods mostly involve manual hand-held grinding heads to remove burrs. This method is inefficient and requires a lot of manpower and resources. Summary of the Invention

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] I. This invention uses a grinding component to simultaneously grind the outer and inner sides of irregularly shaped thin-walled shells, and can adapt to shells of different thicknesses. The operating mechanism is characterized by the fact that during the deburring process of irregularly shaped thin-walled shells, the shell wall will inevitably not maintain a uniform thickness. If adaptive treatment is not carried out in time, there may be situations where local areas are ground too much or too little. This method, through elasticity, can always elastically clamp the inner wall of the shell, so that when the thickness of the shell wall changes, the elastic structure can automatically make fine adjustments to maintain the uniformity of the overall grinding.

[0032] II. This invention, through the operation of the driving mechanism and under the action of the adapting mechanism, drives the grinding component to move and grind along the shell wall of the irregularly shaped thin-walled shell, and adapts to various shapes of irregularly shaped thin-walled shells. This operating mechanism has the following features:

[0033] Technical point 1: This method can, to a certain extent, meet the automatic grinding needs of some irregularly shaped shells, thereby improving the efficiency of deburring;

[0034] Technical point 2: This method can polish both the inner and outer walls of the shell at the same time, eliminating the need for multiple polishing operations. A single polishing operation can achieve the effect of simultaneous polishing of both the inner and outer walls, thus improving work efficiency and greatly saving production time.

[0035] Technical point 3: This method can achieve a certain degree of all-round polishing effect. The polishing component can slide along the shell wall, so it can perform efficient deburring operations on dead corners or areas that are not easy to polish, resulting in higher work efficiency.

[0036] III. This invention, through the operation of the drive mechanism, drives the grinding component to rotate and grind under the action of the transmission mechanism. Furthermore, the operation of the grinding component and the adaptation mechanism does not affect the power transmission of the transmission mechanism. This operating mechanism possesses the following characteristics:

[0037] Technical point 1: This method does not require the use of multiple motors. Power transmission can be achieved through belt power transmission, and power transmission can still be achieved when the movement of the mechanism changes, thus reducing production and installation costs.

[0038] Technical point two: This method uses a triangular belt drive to adapt to different distance changes. The elastic structure of pulley one and pulley two can always keep the belt tensioned, avoiding the situation of low transmission efficiency when the belt is loose. Therefore, it can still maintain stable transmission after the distance is adjusted, and has better practicality and intelligence. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Please see Figures 1 to 10This embodiment provides a deburring device for processing irregular thin-walled shells, including: a base 1, an adsorption platform 2 installed on the upper surface of the base 1, and a fixing component 3 installed on the upper surface of the base 1.

[0052] More specifically, in this embodiment: the adsorption platform 2 can perform negative pressure adsorption of irregular thin-walled shells, playing an excellent role in positioning and fixing, and with the cooperation of the fixing component 3, it achieves a stable effect of multi-point fixing.

[0053] Furthermore, in this embodiment: the outer shell of the lifting device 4 is fixedly connected to the upper surface of the base 1, and the telescopic end of the lifting device 4 is fixedly connected to the top plate 5.

[0054] More specifically, in this embodiment: the deburring device on the top plate 5 can be moved vertically by the lifting device 4, which makes it easier for the user to install the irregularly shaped shell at the beginning and plays a role in avoiding obstacles.

[0055] Furthermore, in this embodiment: the grinding component is used to simultaneously grind the outer and inner sides of the irregular thin wall, and can adapt to shells of different thicknesses.

[0056] More specifically, in this embodiment: the grinding component can automatically adjust when the shell wall thickness is uneven, preventing the grinding degree from being too high or too low. Therefore, it has excellent intelligent and automated effects, significantly improving the deburring effect. This method has the following advantages:

[0057] During the deburring process of irregularly shaped thin-walled shells, the shell wall will inevitably not maintain a uniform thickness. If adaptive treatment is not carried out in time, there may be cases where the local area is ground too much or too little. This method uses elasticity to keep the inner wall of the shell elastically clamped at all times. When the thickness of the shell wall changes, the elastic structure can automatically make fine adjustments to maintain the uniformity of the overall grinding.

[0058] Furthermore, in this embodiment: through the operation of the drive mechanism, under the action of the adaptation mechanism, the grinding component is driven to move and grind along the shell wall of the irregular thin-walled shell, and adapts to various shapes of irregular thin-walled shells.

[0059] More specifically, in this embodiment: to adapt to the grinding of irregularly shaped shells, a drive mechanism is used to operate, and under the action of the adaptation mechanism, the grinding component is moved and ground along the shell wall of the irregularly shaped thin-walled shell. This method has the following features:

[0060] Firstly, this method can, to a certain extent, satisfy the automatic grinding of some irregularly shaped shells, thus improving the efficiency of deburring.

[0061] Secondly, this method can simultaneously polish both the inner and outer walls of the shell, eliminating the need for multiple polishing operations. A single polishing operation can achieve the effect of simultaneous polishing of both the inner and outer walls, thus improving work efficiency and significantly saving production time.

[0062] Furthermore, this method can achieve a certain degree of all-around polishing effect. The polishing components can slide along the shell wall, so it can efficiently deburr dead corners or areas that are difficult to polish, resulting in higher work efficiency.

[0063] Furthermore, in this embodiment: through the operation of the drive mechanism, the grinding component is driven to rotate and grind under the action of the transmission mechanism, and the power transmission of the transmission mechanism is not affected when the grinding component and the adaptation mechanism are operating.

[0064] More specifically, in this embodiment: the transmission mechanism of this strip can always maintain a stable power transmission, and has the following features:

[0065] Firstly, this method eliminates the need for multiple motors, as power transmission can be achieved through belt drive. Furthermore, power transmission can continue even when the mechanism undergoes changes in movement, thus reducing production and installation costs.

[0066] Secondly, this method uses a triangular belt drive to adapt to different distance changes. The elastic structure of pulley 23 and pulley 24 ensures that the belt is always taut, preventing low transmission efficiency when the belt is loose. Therefore, it can maintain stable transmission even after distance adjustment, making it more practical and intelligent.

[0067] Furthermore, in this embodiment: the outer casing of the motor 6 is fixedly connected to the lower surface of the top plate 5, and an opening is provided on the upper surface of the top plate 5 for the tube 7 to pass through and to be rotatably connected to it on a fixed axis. The outer surface of the tube 7 is connected to the rotating part of the motor 6 through a gear transmission mechanism 8.

[0068] More specifically, in this embodiment: the operation of the rotating part of the motor 6, and the action of the gear transmission mechanism 8, drives the tube body 7 to rotate, providing power for the subsequent mechanisms of this device.

[0069] Furthermore, in this embodiment: one end of the connector 9 is fixedly connected to the outer surface of the tube body 7, the other end of the connector 9 is slidably sleeved with a moving block 10, the moving block 10 and the opposite side of the connector 9 are both fixedly connected with a spring, and the end of the moving block 10 is fixedly connected with a transmission shell 11.

[0070] More specifically, in this embodiment: through the sliding fit between the connector 9 and the moving block 10, and under the elastic force of the spring, the moving block 10 and the transmission housing 11 always have a certain elastic force. Therefore, through this elastic force and the sliding relationship, it can adapt to various irregularly shaped housings, allowing the grinding assembly to slide on the housing wall, thus having good applicability.

[0071] Furthermore, in this embodiment: a spring is fixedly connected inside the telescopic rod 12, one end of the telescopic rod 12 is fixedly connected to the inner wall of the transmission housing 11, a connecting block 13 is fixedly connected to the telescopic end of the telescopic rod 12, an opening 2 is opened on the surface of the connecting block 13, a rotating rod 14 is rotatably connected to the opening wall of the opening 2, and a sliding groove is opened on the outer surface of the transmission housing 11 through which the rotating rod 14 passes and is slidably connected.

[0072] More specifically, in this embodiment: under the action of the two telescopic rods 12 and their internal springs, the telescopic ends of the telescopic rods 12 have a certain elastic force, so that the two connecting blocks 13 are subjected to relative forces.

[0073] Furthermore, in this embodiment: a pressure cylinder 15 is rotatably connected to the outer surface of the rotating rod 14, and a grinding rod 16 is fixedly connected to the outer surface of the rotating rod 14.

[0074] More specifically, in this embodiment: the two connecting blocks 13 can drive the pressing cylinder 15 and the grinding rod 16 to move relative to each other, so as to clamp the shell wall of the irregular shell and adjust adaptively as the shell wall thickness changes.

[0075] Furthermore, in this embodiment: one end of the fixing rod 17 is fixedly connected to the lower surface of the top plate 5, and the other end of the fixing rod 17 is fixedly connected to a toothed ring 18; the surface of the connecting member 9 is rotatably connected to a connecting shaft 19; a sliding opening is provided on the upper surface of the transmission housing 11 for the rotating rod 14 to pass through; the rotating rod 14 and the connecting shaft 19 are connected by a belt pulley transmission mechanism 21; an annular groove is provided on the lower surface of the top plate 5 for the connecting shaft 19 to pass through and slide with it; and a gear 40 is fixedly connected to the outer surface of the rotating rod 14.

[0076] More specifically, in this embodiment: the gear ring 18 is in a fixed state. Through the revolution of the connecting member 9, it can drive the connecting shaft 19 to revolve. Under the meshing transmission, it drives the connecting shaft 19 and the gear 40 to rotate. Thus, when the connecting member 9 rotates, it can drive the grinding component to slide along the shell wall. At the same time, it can drive the grinding component to rotate, so that it can move and grind at the same time, improving the deburring efficiency.

[0077] Furthermore, in this embodiment: a rotating ring 25 is rotatably connected to the outer side of the toothed ring 18, and a telescopic member 26 is fixedly connected to the end of the rotating ring 25. The end of the telescopic member 26 is fixedly connected to the outer surface of the transmission housing 11, and a connecting plate 27 is fixedly connected to the outer surface of the rotating ring 25. A groove is provided on the upper surface of the connecting plate 27 for the slider 28 to be inserted and slidably connected thereto. The upper surface of the slider 28 is rotatably connected to the lower end of the shaft of the pulley 23. A telescopic member 29 is fixedly connected to the side of the slider 28, and the outer shell of the telescopic member 29 is fixedly connected to the groove wall of the groove.

[0078] More specifically, in this embodiment: the pulley 23 is used to make the belt side length on the pulley transmission mechanism 21 longer, and through the telescopic member 29 and the spring structure inside it, the belt of the pulley transmission mechanism 21 can always be kept taut, and the belt side length can also adapt to the change of the displacement distance of the transmission housing 11, and has the effect of still being able to rotate and transmit after the displacement changes.

[0079] Furthermore, in this embodiment: a fixing plate 30 is fixedly connected to the side of the transmission housing 11, and a groove 2 is provided on the upper surface of the fixing plate 30 for the slider 2 31 to be inserted and slidably connected thereto. The upper surface of the slider 2 31 is fixedly rotatably connected to the lower end of the shaft of the pulley 2 24. A telescopic member 32 is fixedly connected to the side of the slider 2 31, and the outer shell of the telescopic member 32 is fixedly connected to the groove wall of the groove 2.

[0080] More specifically, in this embodiment: the second pulley 24 is used to always maintain the belt tension of the second pulley transmission mechanism 22, so that when the distance between the two pressure cylinders 15 is adjusted, the second pulley 24 can be moved by the telescopic member 32 and the spring structure inside the telescopic member 32 to adapt to the change of distance, and at the same time, the belt can always be tightened to maintain transmission.

[0081] Furthermore, in this embodiment: connecting rods 33 are rotatably connected to the outer surfaces of the two connecting blocks 13 at a fixed axis; a groove 3 is provided on the outer surface of the transmission housing 11 for the connecting rods 33 to pass through and slide with them; the ends of the two connecting rods 33 are hinged to hinge plates 34; the ends of the two hinge plates 34 are hinged to a rotating plate 35; a handle 36 is fixedly connected to the center of the rotating plate 35; and the end of the handle 36 is rotatably connected to the outer surface of the transmission housing 11 at a fixed axis.

[0082] More specifically, in this embodiment: when it is necessary to clamp the pressure cylinder 15 and the grinding rod 16 onto the inner wall of the thin-walled housing, since the housing wall may have a certain thickness, the user needs to pry the grinding rod 16 to separate them for clamping. However, this method is inconvenient and may require the assistance of professional tools. In this method, the user twists the handle 36 to rotate the rotating plate 35. Through the hinge relationship and the lateral limitation of the connecting block 13, the two connecting blocks 13 move in opposite directions. Therefore, the distance between the two pressure cylinders 15 is opened to allow the housing wall to be inserted, which improves the ease of installation, work efficiency and safety.

[0083] Furthermore, in this embodiment: a purification device 37 is fixedly installed on the upper surface of the top plate 5, and an air inlet pipe 38 is fixedly connected to the side of the purification device 37. The end of the air inlet pipe 38 is rotatably connected to the upper end of the pipe body 7 and communicates with the pipe body 7. An air pump is installed inside the air inlet pipe 38. An air intake shell 39 is fixedly connected to the end of the pipe body 7, and an air inlet is opened at the bottom of the air intake shell 39.

[0084] More specifically, in this embodiment: when deburring is performed, the air pump draws air in, and the suction shell 39 is positioned inside or above the opening of the irregular thin-walled shell without affecting the normal operation of deburring. During deburring, a large amount of debris is inevitably generated. If the debris floats in the air, it may affect the health of the user. Therefore, this method uses suction to draw the debris from the air inlet below the suction shell 39 into the pipe 7, and finally into the purification device 37 for dust reduction and purification. This ensures that the emitted gas will not harm the health of the user and helps to ensure the air quality of the working environment. It can be used with sensors to check the amount of debris or suspended matter in real time, and to increase the operation of the air pump in a timely manner to reduce the amount of floating debris and increase the processing efficiency.

[0085] It is worth noting that when the suction shell 39 is inside or above the shell opening, it has a certain function of blocking debris from splashing, thus preventing debris from falling and jumping around and affecting the working environment.

[0086] Working Principle: This deburring equipment for processing irregularly shaped thin-walled shells is used when the shell has an irregular shape that distinguishes it from existing products. It can be applied to the shells of some products or mechanical structures with unique features. Regular shells generally have a standard cross-section, such as a circle or rectangle, while irregularly shaped shells may have a cross-section with certain undulations or depressions, forming an irregular shape with a unique appearance to meet production needs. This invention focuses on improving the deburring process for shells with the same cross-section at different heights but irregular cross-sectional shapes. The shell walls of irregularly shaped thin-walled shells are inevitably thinner, and after the initial processing, some burrs are unavoidable on the outer surface and inner wall. To avoid these burrs affecting the subsequent shell forming quality, they need to be removed. However, due to the irregular shape of the shell, existing methods are not suitable for rapid mechanical processing and are mostly done manually, resulting in low processing efficiency.

[0087] In this method, the bottom of the housing is first placed on the adsorption platform 2, with the upper opening of the housing aligned with the center of the top plate 5. The adsorption platform 2 has a certain adsorption and positioning effect, specifically using negative pressure adsorption to securely lock the housing. Then, the fixing component 3 is activated. The fixing component 3 can be a screw-driven mechanism or a cylinder-driven mechanism to apply multi-point pressure to the side of the housing. This not only positions the housing in the center of the top plate 5 but also provides multi-point locking to prevent the housing from shaking during deburring. After the preparation process is completed, the lifting device 4 moves the two opposing grinding rods 16 downwards together, causing the two grinding rods 16 to simultaneously clamp the inner and outer sides of the housing's inner wall, and are positioned by the pressure cylinder 15. The lifting device 4 can be implemented using existing electric push rods, cylinders, or screw-driven mechanisms, which play a role in avoiding obstacles during housing installation and improve installation efficiency. At this point, work can begin.

[0088] When adapting to irregularly shaped shells, the operation of the rotating part of the motor 6, through the gear transmission mechanism 8, drives the tube body 7 to rotate. As the tube body 7 rotates, it drives the connecting piece 9 to rotate. Since the connecting piece 9 and the moving block 10 are in a sliding fit relationship, and there is an elastic structure between the moving block 10 and the connecting piece 9, an elastic force is applied to the moving block 10, allowing the two grinding rods 16 to move synchronously along the inner and outer sides of the shell. Furthermore, since the movement trend of the connecting piece 9 is rotational,... Furthermore, due to the sliding fit and the elastic application of force, the two pressure cylinders 15 can slide along the inner and outer walls of the shell with different shapes. This adapts to shells of different shapes. The pressure cylinders 15 and the grinding rods 16 are synchronized, with the pressure cylinders 15 serving as a positioning aid for the grinding rods 16. Therefore, the two adjacent grinding rods 16 can slide along the inner and outer walls of the shell, and in conjunction with the rotation of the grinding rods 16, they can ultimately grind the inner and outer walls of the shell to remove burrs. This method possesses the following advantages:

[0089] First: Unlike existing methods, when deburring irregularly shaped shells, manual grinding is usually the only option due to the irregular shape. This method is suitable for irregularly shaped shells with the same cross-section, focusing on deburring shells with irregular cross-sections. For conical or other objects with different cross-sectional sizes, this method can also use the method of changing the grinding rod 16 to grind layer by layer. This method can meet the automatic grinding needs of some irregularly shaped shells to a certain extent, thus improving the efficiency of deburring.

[0090] Second: This method can polish both the inner and outer walls of the shell at the same time, eliminating the need for multiple polishing operations. A single polishing operation can achieve the effect of polishing both the inner and outer walls simultaneously, thus improving work efficiency and greatly saving production time.

[0091] Third: This method can achieve a certain degree of all-round polishing effect. Because it can slide along the shell wall, it can efficiently deburr dead corners or areas that are difficult to polish, resulting in higher production efficiency.

[0092] When adapting to different wall thicknesses at various locations on an irregularly shaped shell, the telescopic rod 12 and its internal spring structure consistently provide relative elastic force to the two connecting blocks 13. This simultaneously applies relative force to the lower pressure cylinder 15 and the grinding rod 16, ensuring the two pressure cylinders 15 remain in constant contact with the shell wall. Consequently, the contact distance between the grinding rod 16 and the inner and outer walls of the shell is maintained at a certain level due to elasticity. Therefore, when the inner wall of the shell thickens or thins, this elasticity allows the grinding rod 16 to automatically adapt, ensuring consistent overall shell grinding to a certain extent. This method provides:

[0093] During the deburring process of irregularly shaped thin-walled shells, the shell walls will inevitably not maintain a uniform thickness. If adaptive treatment is not carried out in time, local areas may end up being over- or under-ground. The degree of grinding depends on the distance between the grinding structure and the object to be ground. This method can use this elastic relationship to keep the inner wall of the shell elastically clamped at all times. When the thickness of the shell wall changes, the elastic structure can automatically make fine adjustments to maintain the uniformity of the overall grinding.

[0094] During grinding, the grinding rod 16 must be driven to rotate. The rotation of the connecting part 9 drives the connecting shaft 19 and the gear 40 to revolve around the tube body 7. During the revolution, the gear 40 meshes with the fixed gear ring 18, which causes the gear 40 to rotate. The rotation is transmitted to the rotating rod 14 through the belt pulley transmission mechanism 21, so that the two rotating rods 14 rotate synchronously after being transmitted by the belt pulley transmission mechanism 22, which in turn drives the grinding rod 16 to rotate, thus achieving the prerequisite for grinding and deburring.

[0095] However, it is worth noting that because this device has a wide range of adaptability, the extension distance between its mechanisms will change during operation. Existing power transmission methods cannot effectively adapt to this change in distance. Directly setting multiple motors to drive multiple grinding rods 16 would only increase production and usage costs significantly. This method can use a simpler belt drive and adaptable structure to balance and meet the displacement changes in this part. When the connecting piece 9 and the moving block 10 extend, the distance between the rotating rod 14 and the connecting shaft 19 will inevitably increase, while the connecting shaft 19 will not extend. Therefore, during this movement, the belt can be pulled. Wheel 23 moves in a direction close to the belt drive mechanism 21, tightening the belt to lengthen it and enabling continuous transmission. The outermost pulley 24 balances the expansion and contraction of the belt drive mechanism 22. Pulleys 23 and 24 apply elastic force through the elastic structures inside the telescopic components 29 and 32, respectively, ensuring a constant force on both belt segments and maintaining belt tension for stable transmission. Furthermore, the device revolves synchronously with the grinding rod 16, guaranteeing its functionality. This method possesses the following advantages:

[0096] First, unlike the method of using multiple motors to achieve the rotation of the grinding rod 16 for grinding operations, this method does not require multiple motors. Power transmission can be achieved through belt power transmission, and power transmission can still be achieved when there are changes in the movement of the mechanism. Therefore, the production and installation costs are reduced. In other embodiments, multiple sets of adjacent grinding rods 16 can be applied to rotate through the connecting member 9, which can drive multiple grinding rods 16 to rotate and revolve to achieve grinding and improve grinding efficiency.

[0097] Second: In order to achieve the change in movement, this method uses a triangular belt drive to adapt to the change in distance. The elastic structure of pulley 23 and pulley 24 can keep the belt taut at all times, avoiding the low transmission efficiency that would occur when the belt is loose. Therefore, it can still maintain stable transmission after the distance is adjusted, and has better practicality and intelligence.

[0098] like Figures 8-10 The various irregularly shaped shells listed in this invention can be used in production and applications in different fields, for example... Figure 8 The two grinding rods 16 can slide and grind along the shell wall of the irregularly shaped thin-walled shell. When in recessed or protruding areas, they can adapt to different shapes through an adaptation and transmission mechanism. Existing thin-walled shells generally do not have sharp edges to avoid jamming of the device. Figure 9 This is also the case, for example Figure 10 This device can also be adapted to existing products. This product is a cross-sectional view of a speaker enclosure. This method can also be adapted to similar enclosures, such as chassis enclosures, heat dissipation instrument enclosures, etc. Therefore, this method has a wide range of application prospects and is also applicable to applications with regular shapes but different wall thicknesses.

[0099] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
