Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a die-casting corner deburring structure. Background Art

[0002] The die-casting corner deburring structure is a process equipment used to improve the surface quality of die-casting products. It is mainly used to remove burrs generated during the die-casting production process. The development prospects and application fields of this structure are closely related to the development of the manufacturing industry. The development prospects of the die-casting corner deburring structure are very broad. With the continuous advancement of industrial automation and precision manufacturing technology, the quality requirements for die-casting parts are getting higher and higher, which has prompted the continuous development of deburring technology to meet higher market demands. Therefore, with the increasing demand for high-quality die-casting parts in the manufacturing industry, the development of deburring technology will be given more attention.

[0003] In the prior art, the deburring structure for the corners of die-castings usually uses files or other grinding components to remove excess burrs. When the edge of the die-casting is designed as an irregular curved surface, the positions of these files or grinding components are often fixed. It is difficult for them to completely cover and contact all burr areas when facing the irregular curved surface. Workers must manually clean these hard-to-reach areas, which not only increases the labor intensity, but also significantly prolongs the time of the entire grinding process. Since the grinding component cannot be accurately positioned to the area that needs to be polished, the edges that do not need to be polished will be over-polished, resulting in inaccurate product dimensions. Excessive polishing will damage the surface of the die-casting, causing the generation of micro cracks, and reducing the overall strength and durability of the product. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a die casting corner deburring structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a deburring structure for the corners of a die-casting part, comprising a bottom plate, a fixing column is fixed with a linear array on the top of the bottom plate, a connecting rail is fixed on one side of the fixing column, a mounting column is fixed with a linear array on the top of the bottom plate, a fan groove is provided on the circumference of the mounting column, a limiting slide groove is provided on the top of the fan groove, a circular groove is provided on one side of the inner wall of the fan groove, a clamping spring is fixed on the inner wall of the circular groove, a fan-shaped part is fixed on one end of the clamping spring, the surface of the fan-shaped part is slidably connected to the inner wall of the fan groove, a limiting column is fixed on the top of the fan part, and the side surface of the limiting column is connected to the limiting slide groove. The inner wall of the control slide is slidably connected, the top of the limiting column is rotatably connected with a rotating column, the circumferential surface of the rotating column is provided with a rubbing brush, the rotating column is driven by a motor, the top of the rotating column is rotatably connected with a top column, the motor is arranged on the inner wall of the top column, a fan-shaped piece is fixed on the top of the top column, a connecting column is fixed on the fan-shaped piece, a sliding top column is rotatably connected to the top of the connecting column, and the circumferential surface of the sliding top column is slidably connected with the inner wall of the connecting rail. In the prior art, the die-casting edge deburring structure usually uses a file or other grinding components to remove excess burrs. When the edge of the die-casting is designed as an irregular curved surface, the positions of these files or grinding components are often fixed. When facing irregular surfaces, it is difficult for them to completely cover and contact all burr areas. Workers must manually clean these hard-to-reach areas, which not only increases labor intensity, but also significantly prolongs the time of the entire grinding process. Since the grinding components cannot be accurately positioned to the areas that need to be polished, the edges that do not need to be polished will be over-polished, resulting in inaccurate product dimensions. Excessive polishing will damage the surface of the die-casting, causing micro cracks and reducing the overall strength and durability of the product. In response to such problems, the utility model adopts the method of installing a roughening brush to solve the problem, which realizes that when the robot arm moves the die-casting When it is fed between the roughening brushes, the convex part of the edge of the die-casting squeezes the roughening brush, causing the roughening brush to move to one side of the fixed column, pulling the top column and the limiting column to make both move along the limiting slide groove, the fan-shaped part leaves the fan groove, and the fan-shaped part relies on its own structural characteristics to prevent the component from moving skew, stretching the compression spring, and the elastic potential energy makes the roughening brush fit tightly against the surface of the die-casting, so that multiple roughening brushes are tightly covered on the surface of the die-casting, thereby improving the deburring effect of the corners of the die-casting. At the same time, the rotating connection between the sliding top column and the connecting column greatly reduces the friction between the sliding top column and the inner wall of the connecting rail, preventing the component from skewing, thereby improving work efficiency and increasing product service life.

[0006] Preferably, limiting side grooves are provided on both sides of the inner wall of the connecting rail member, and the inner wall of the limiting side groove is slidably connected with a wing member, a baffle is fixed at one end of the wing member, a buffer spring is fixed to one side of the baffle, and one end of the buffer spring is fixed to one end of the inner wall of the connecting rail member. In the prior art, when the die-casting enters at a faster speed and has a larger volume, its raised edge will cause the component to move quickly, causing the sliding top column to collide with the inner wall of the connecting rail member, and the rubbing brush to scratch the fixed column, causing damage to the equipment. To solve this problem, the utility model solves it by installing a buffer spring, so that when the die-casting enters the processing area, the sliding top column moves toward the side of the fixed column, the sliding top column contacts the baffle, compresses the buffer spring to generate resistance, and causes the sliding top column to be subject to resistance, thereby preventing the component from moving too fast, thereby achieving the effect of increasing the service life of the equipment.

[0007] Preferably, a trapezoidal groove is provided in a circumferential array on the circumferential surface of the rotating cylinder, and a trapezoidal piece is slidably connected to the inner wall of the trapezoidal groove, and one side of the trapezoidal piece is fixed to the inner wall of the roughening brush. In the prior art, the roughening brush is always subjected to resistance from the surface of the die-casting when in use, which causes the fixing points of the roughening brush fixed by gluing or welding to easily fall off, making the equipment unable to operate and reducing the service life of the equipment. To solve this problem, the utility model adopts the method of installing trapezoidal pieces to achieve a solution, and realizes that through the coordination of the trapezoidal piece and the trapezoidal groove, the connection and fixing stability of the roughening brush is greatly increased, and the roughening brush is prevented from falling off, thereby achieving the effect of increasing the service life of the equipment.

[0008] Preferably, a chip removal air duct is opened on the inner wall of the bottom plate, and an air exhauster is provided on the inner wall of the chip removal air duct. The chip removal air duct removes the fallen burrs from the top of the bottom plate to prevent the subsequent production from being affected and improve the yield rate.

[0009] Preferably, a two-way anti-skid groove is provided at the bottom of the base plate to increase the friction between the base plate and the ground, prevent the equipment from slipping, and improve production safety.

[0010] Preferably, the bottom plate is configured as a quadrangular pyramid, which increases the contact area between the bottom plate and the ground without increasing the material consumption, thereby increasing the friction and improving production safety.

[0011] Preferably, the diameter of the mounting column is larger than the diameter of the rotating column, so as to prevent the roughening brush from sliding down due to gravity and improve the stability of the equipment.

[0012] Beneficial Effects

[0013] 1. In the prior art, the deburring structure of die-casting corners usually uses files or other grinding components to remove excess burrs. When the edge of the die-casting is designed as an irregular curved surface, the position of these files or grinding components is often fixed. It is difficult for them to completely cover and contact all burr areas when facing the irregular curved surface. Workers must manually clean these hard-to-reach areas, which not only increases the labor intensity, but also significantly prolongs the time of the entire grinding process. Since the grinding component cannot be accurately positioned to the area that needs to be polished, it will cause over-grinding of the edges that do not need to be polished, resulting in inaccurate product dimensions. Excessive grinding will damage the surface of the die-casting, causing the generation of micro cracks, and reducing the overall strength and durability of the product. The cam is pressed against the top of the die casting and the cam is pressed against the top of the die casting to release the cam which in turn moves the die casting to the bottom of the die casting.

[0014] 2. In the prior art, when the die-casting enters at a fast speed and has a large volume, its raised edge will cause the assembly to move quickly, causing the sliding top column to collide with the inner wall of the connecting rail, and the rubbing brush to scratch the fixed column, causing equipment damage. To address this problem, the utility model solves it by installing a buffer spring, so that when the die-casting enters the processing area, the sliding top column moves toward the fixed column, the sliding top column contacts the baffle, and the buffer spring is compressed to generate resistance, so that the sliding top column is subject to resistance, preventing the assembly from moving too fast, thereby achieving the effect of increasing the service life of the equipment.

[0015] 3. In the prior art, the roughening brush is always subject to resistance from the surface of the die-casting when in use, which causes the fixing points of the roughening brush fixed by gluing or welding to easily fall off, making the equipment unable to operate and reducing the service life of the equipment. To solve this problem, the utility model adopts the method of installing trapezoidal parts, which realizes the combination of trapezoidal parts and trapezoidal grooves, greatly increases the connection and fixing stability of the roughening brush, prevents it from falling off, and achieves the effect of increasing the service life of the equipment.

The rotating column 206 is driven by a motor, and a top column 208 is rotatably connected to the top of the rotating column 206. The motor is arranged on the inner wall of the top column 208, and a fan-shaped piece 202 is fixed on the top of the top column 208. A connecting column 209 is fixed on the fan-shaped piece 202, and a sliding top column 2010 is rotatably connected to the top of the connecting column 209. The circumference of the sliding top column 2010 is slidably connected to the inner wall of the connecting rail 2011. The deburring structure of the corners of the die casting usually adopts a file or other grinding components to remove excess burrs. When the edge of the die casting is designed as an irregular curved surface, the positions of these files or grinding components are often fixed. They When facing irregular surfaces, it is difficult to completely cover and contact all burr areas. Workers must manually clean these hard-to-reach areas, which not only increases labor intensity, but also significantly prolongs the time of the entire grinding process. Since the grinding component cannot be accurately positioned to the area that needs to be polished, the edges that do not need to be polished will be over-polished, resulting in inaccurate product dimensions. Over-polishing will damage the surface of the die-casting, causing micro cracks and reducing the overall strength and durability of the product. The problem is solved by installing a roughening brush 207, which is implemented so that when the robot arm feeds the die-casting between the roughening brushes 207, the convex part of the edge of the die-casting squeezes the roughening brush 207, so that the roughening brush 207 is 07 moves toward the side of the fixed column 2012, pulling the top column 208 and the limiting column 205 to make the two move along the limiting slide groove 204, and the fan-shaped part 202 leaves the fan groove 201, and the fan-shaped part 202 relies on its own structural characteristics to prevent the component from moving crookedly, stretching and clamping the spring 203, and the elastic potential energy makes the roughening brush 207 fit tightly with the surface of the die-casting, so that multiple roughening brushes 207 are tightly coated on the surface of the die-casting, thereby improving the deburring effect of the corners of the die-casting. At the same time, the rotational connection between the sliding top column 2010 and the connecting column 209 greatly reduces the friction between the sliding top column 2010 and the inner wall of the connecting rail 2011, thereby preventing the component from being skewed, thereby improving work efficiency and increasing the service life of the product.The circumferential array of the rotating column 206 is provided with a trapezoidal groove 4, and the inner wall of the trapezoidal groove 4 is slidably connected with a trapezoidal member 401, and one side of the trapezoidal member 401 is fixed to the inner wall of the roughening brush 207. The roughening brush 207 is always subject to resistance from the surface of the die casting when in use, which causes the fixing point of the roughening brush 207 fixed by gluing or welding to fall off easily, making the equipment unable to operate, reducing the service life of the equipment. The installation of the trapezoidal member 401 is used to solve this problem, and the combination of the trapezoidal member 401 and the trapezoidal groove 4 greatly increases the connection and fixing stability of the roughening brush 207, prevents it from falling off, and achieves the effect of increasing the service life of the equipment. The diameter of the mounting column 2 is larger than the diameter of the rotating column 206, which prevents the roughening brush 207 from sliding down due to gravity and improves the stability of the equipment.

[0028] Limiting side grooves 3 are provided on both sides of the inner wall of the connecting rail 2011, and the inner wall of the limiting side groove 3 is slidably connected with a wing piece 301, a baffle 302 is fixed at one end of the wing piece 301, and a buffer spring 303 is fixed to one side of the baffle 302, and one end of the buffer spring 303 is fixed to one end of the inner wall of the connecting rail 2011. When the die-casting enters at a fast speed and has a large volume, its raised edge will cause the component to move quickly, causing the sliding top column 2010 to collide with the inner wall of the connecting rail 2011, and the rubbing brush 207 to scratch the fixed column 2012, causing equipment damage. The problem is solved by installing a buffer spring 303, so that when the die-casting enters the processing area, the sliding top column 2010 moves toward the side of the fixed column 2012, the sliding top column 2010 contacts the baffle 302, and the buffer spring 303 is compressed to generate resistance, so that the sliding top column 2010 is subjected to resistance, preventing the component from moving too fast, thereby achieving the effect of increasing the service life of the equipment. The inner wall of the bottom plate 1 is provided with a chip removal duct 102, and the inner wall of the chip removal duct 102 is provided with an air extractor. The chip removal duct 102 removes the fallen burrs from the top of the bottom plate 1 to prevent the subsequent production from being affected and improve the yield rate. A two-way anti-skid groove 101 is provided at the bottom of the bottom plate 1 to increase the friction between the bottom plate 1 and the ground, prevent the equipment from slipping, and improve production safety. The bottom plate 1 is set as a quadrangular platform to increase the contact area between the bottom plate 1 and the ground without increasing the material, thereby increasing the friction and improving production safety.

[0029] The working principle of the utility model is as follows: when the robot arm delivers the die casting into the space between the roughening brushes 207, the convex part of the edge of the die casting squeezes the roughening brush 207, so that the roughening brush 207 moves toward the side of the fixed column 2012, and pulls the top column 208 and the limiting column 205 to make both move along the limiting slide groove 204, the fan-shaped member 202 leaves the fan groove 201, and the fan-shaped member 202 relies on its own structural characteristics to prevent the movement of the component from being skewed, and the compression spring 203 is stretched, and the elastic potential energy makes the roughening brush 207 fit closely with the surface of the die casting, so that multiple The roughening brush 207 is tightly wrapped around the surface of the die-casting to improve the deburring effect of the edges and corners of the die-casting. At the same time, the rotational connection between the sliding top column 2010 and the connecting column 209 greatly reduces the friction between the sliding top column 2010 and the inner wall of the connecting rail 2011 to prevent the component from tilting. When the die-casting enters the processing area, the sliding top column 2010 moves toward the side of the fixed column 2012, the sliding top column 2010 contacts the baffle 302, and the compression buffer spring 303 generates resistance, so that the sliding top column 2010 is subjected to resistance to prevent the component from moving too fast.
