Description

Technical Field

[0001] This invention relates to the field of grinding technology for die-cast aluminum parts, specifically to a device for grinding and deburring the surface of die-cast aluminum parts. Background Technology

[0002] Die-cast aluminum parts are a type of pressure-casting component. They are produced using a pressure casting machine equipped with a casting mold. Molten aluminum or aluminum alloy is poured into the feed inlet of the die-casting machine, and then the machine casts aluminum or aluminum alloy parts into shapes and sizes defined by the mold. After the die-cast aluminum parts are formed, their surfaces are relatively rough and have burrs. Therefore, it is necessary to grind the surface of the parts on a grinding lathe to remove the burrs and smooth the rough areas.

[0003] Currently, die-cast aluminum parts deburred by grinding are generally cylindrical. Grinding lathes typically consist of clamping components, moving components, and a grinding machine. When grinding the surface of a cylindrical die-cast aluminum part, the process involves two steps. First, the worker uses the three-jaw clamping mechanism on the lathe to locate the center axis of the part. The worker needs to hold the part with one hand and operate the clamping component with the other. The cumbersome clamping process affects subsequent operations, resulting in low grinding efficiency. Furthermore, most current grinding lathes are horizontally placed, occupying a large area and resulting in low space utilization. Additionally, the dust generated during grinding can easily splash onto the worker and the worktable, so it is necessary to intercept and collect the dust generated during grinding.

[0004] On the other hand, a patent with publication number CN114434226B discloses an external cylindrical grinding machine. This device, by setting an adjusting column and a connecting column, allows the height of the support column to be adjusted, facilitating the grinding of workpieces of different diameters for arc or curved surface machining. However, current grinding lathes use a three-jaw clamping component to fix the cylindrical die-cast aluminum part. This results in the area on the surface of the die-cast aluminum part covered by the three-jaw clamping component not being able to be ground. This requires the operator to disassemble the clamped die-cast aluminum part, change the clamping end, and perform a second lathe loading. This leads to discontinuous grinding operations on the die-cast aluminum part, reducing grinding efficiency.

[0005] To address these issues, we provide a device for grinding and deburring the surface of die-cast aluminum parts. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for grinding and deburring the surface of die-cast aluminum parts, including a support plate, a protective cylinder, and two symmetrical clamping mechanisms. The protective cylinder is located between the two clamping mechanisms and is fixed to the outer surface of the support plate. Both clamping mechanisms are provided with electric rails for lifting and lowering the clamping mechanisms, and both electric rails are fixed to the outer surface of the support plate.

[0007] The clamping mechanism includes a movable seat fixed on an electric track support. A sleeve is fixed to one end of the movable seat away from the electric track. A rotating block is rotatably connected to the inner wall of the sleeve. A drag shaft is fixed to the bottom surface of the rotating block. A fixed disk is fixed to the bottom end of the drag shaft. The outer surface of the fixed disk has four circumferentially arranged square slots. Each of the four square slots is provided with a clamping claw. A linkage component is provided between the four clamping claws and the movable seat to enable the four clamping claws to move simultaneously.

[0008] Each of the four square slots has a set of limiting rods fixed to its inner wall. Each set of limiting rods consists of two rods. Each of the four gripping claws has a sliding block fixed to its upper end. The four sets of limiting rods are slidably connected to the four sliding blocks. The limiting rods increase the stability of the gripping claws during movement and prevent them from moving. One side of the gripping claws is provided with anti-slip texture to increase the friction when the four gripping claws hold the die-cast aluminum parts.

[0009] The aforementioned linkage component includes a sliding tube, which is slidably connected to the outer surface of the drag shaft. Four hinge rods are hinged to the bottom of the sliding tube, and the ends of the four hinge rods away from the sliding tube are respectively hinged to four sliding blocks. When the sliding tube moves up and down, the sliding tube will drive the four clamping claws to move closer or further away at the same time through the four hinge rods.

[0010] The aforementioned linkage assembly also includes an electric telescopic rod, which is fixed to the movable seat. A toggle plate is fixed to the telescopic end of the electric telescopic rod. A groove adapted to the toggle plate is formed on the outer surface of the sliding tube, and the groove is rotatably connected to the toggle plate. The clamping mechanism also includes a motor, which is fixed to the movable seat. A sprocket is fixed to the output end of the motor. A sprocket is fixed to the outer surface of the drive shaft. Sprockets 1 and 2 are connected via chain drive. Two limiting slide bars are fixedly connected to the outer surface of the drive shaft. Both limiting slide bars are slidably connected to the sliding tube. The motor drives sprocket 2 to rotate, and the rotation of sprocket 2 drives the drive shaft to rotate via sprocket 1 and the chain. The rotation of the drive shaft will cause the die-cast aluminum part, held by four clamping claws, to rotate, facilitating grinding of the die-cast aluminum part.

[0011] An auxiliary feeding mechanism is provided above the protective cylinder cavity. The auxiliary feeding mechanism includes four return plates. Each of the four return plates has a limit block two fixed at its bottom and an auxiliary arc plate fixed above each of the four return plates. The protective cylinder includes a sloping inlet fixed above the protective cylinder. The four auxiliary arc plates are adapted to the sloping inlet of the protective cylinder. The interior of the protective cylinder is provided with a spring assembly that clamps the die-cast aluminum part with the four return plates. When the operator feeds the die-cast aluminum part, the die-cast aluminum part is placed between the four return plates and then pressed down. The four limit blocks two will prevent the die-cast aluminum part from moving further down. At the same time, the four return plates are clamped by the spring pressure of the four telescopic springs, so that the columnar die-cast aluminum part becomes vertical after being squeezed. This makes it convenient for the upper clamping mechanism to clamp and fix the upper end of the die-cast aluminum part, and the clamping work can be carried out without the operator holding the die-cast aluminum part.

[0012] Each of the four positioning plates has a long rod fixed to its outer surface. Each of the four long rods has a fixed tube slidably connected to its outer surface. Each of the four fixed tubes is fixedly connected to the inner wall of the protective cylinder. Each of the four long rods has a limit block fixed to its outer surface. Each of the four fixed tubes has four slots on its outer surface. Each of the four slots is slidably connected to the four limit blocks. The fixed tubes increase the stability of the long rods when they move. The limit blocks slide in the slots to prevent the long rods from rotating in the fixed tubes.

[0013] The aforementioned spring assembly includes an annular plate 1, with four hinge rods 2 hinged to the bottom surface of the annular plate 1. The ends of the four hinge rods 2 away from the annular plate 1 are respectively hinged to four limiting blocks 1. The inner wall of the protective cylinder is fixedly connected to four fixing rods, and the four fixing rods are slidably connected to the annular plate 1. Through the hinge between the annular plate 1 and the four hinge rods 2, when the annular plate 1 moves up and down, the four hinge rods 2 will drive the four return plates to move closer to each other or further away from each other.

[0014] The aforementioned spring assembly also includes four telescopic springs, which are respectively sleeved on the outside of four fixed rods. The upper ends of the four fixed rods are fixed with fixed plates, the lower ends of the four telescopic springs are fixed with annular plate one, and the upper ends of the four telescopic springs are fixed with the four fixed plates respectively. When the worker inserts the cylindrical die-cast aluminum part between the four return plates from above the protective cylinder, the four limit blocks two will prevent the die-cast aluminum part from moving further down. At this time, the annular plate one is subjected to the spring pressure of the four telescopic springs and exerts downward force, causing the annular plate one to press the long rod through the hinge rod two and move out of the fixed tube, causing the four return plates to move towards each other. The four return plates will clamp the bottom end of the die-cast aluminum part.

[0015] The auxiliary feeding mechanism also includes an annular plate II. Two electric telescopic rods II are fixed to the inner wall of the protective cylinder. The telescopic ends of the two electric telescopic rods II are fixed to the annular plate II. Four U-shaped top plates arranged in a circular array are fixed to the upper surface of the annular plate II. Four pressure blocks corresponding to the U-shaped top plates are fixed to the outer surface of the annular plate I. After the four clamping claws clamp and fix the die-cast aluminum part, the two electric telescopic rods II are first controlled to drive the annular plate II to move upward, so that the four return plates move away from each other, so that the limiting block II no longer blocks the die-cast aluminum part.

[0016] A collection mechanism is provided below the protective cylinder cavity. The collection mechanism includes a vacuum cleaner, which is fixed to the outer surface of the support plate. The suction end of the vacuum cleaner is fixedly connected to a first suction port. The bottom end of the first suction port is fixedly connected to an annular ventilation pipe, which is fixed to the inner wall of the protective cylinder. The top of the annular ventilation pipe is fixedly connected to a second suction port. Two symmetrical retractable grinding machines are arranged between the first and second suction ports. Both retractable grinding machines are fixed to the inner wall of the protective cylinder. During grinding, the grinding force on the die-cast aluminum parts can be controlled by controlling the depth of the two retractable grinding machines. When the vacuum cleaner is turned on, the dust generated during grinding will be sucked in by the second suction port and the retractable grinding machines. The splashing dust will be blocked by the protective cylinder, effectively intercepting and collecting the generated dust.

[0017] Compared with existing technologies, this die-cast aluminum part surface grinding and deburring device has the following advantages:

[0018] I. This invention, by setting up two clamping mechanisms and an electric track, controls the upper clamping mechanism during the grinding of die-cast aluminum parts. The upper mechanism causes the actuating plate to press against the sliding tube, bringing the four clamping claws closer together. The four claws clamp and fix the upper end of the die-cast aluminum part, and the electric track moves the clamped part downwards. After the bottom end of the die-cast aluminum part is ground by two retractable grinding machines, the bottom end is clamped by the four lower clamping claws. Then, the upper four clamping claws are released, allowing the lower clamping mechanism to continue moving the part downwards to complete the subsequent grinding work. This device, through this staggered clamping method, effectively avoids the problem of the end face of die-cast aluminum parts being difficult to grind. Furthermore, the staggered clamping of the upper and lower ends of the die-cast aluminum part does not affect the grinding process, thus improving the efficiency of the grinding work.

[0019] Second, this invention features an auxiliary feeding mechanism. When feeding die-cast aluminum parts, the worker places the die-cast aluminum parts between four positioning plates and then presses them down. The four limiting blocks prevent the die-cast aluminum parts from moving further down. At the same time, the four positioning plates are clamped by the spring pressure of four telescopic springs, causing the columnar die-cast aluminum parts to become vertical after being squeezed. This facilitates the upper clamping mechanism to clamp and fix the upper end of the die-cast aluminum parts, eliminating the need for the worker to manually hold the die-cast aluminum parts. This improves the feeding efficiency of die-cast aluminum parts during grinding operations, thereby increasing the overall work efficiency.

[0020] Third, this invention, by setting up a protective cylinder and a collection mechanism, can control the grinding force on the die-cast aluminum parts by controlling the depth of the two retractable grinding machines. The dust generated during grinding will be sucked in by the dust inlet and the retractable grinding machines, and the splashing dust will be blocked by the protective cylinder, effectively intercepting and collecting the generated dust. Moreover, the grinding method of vertical movement of the parts will greatly reduce the floor space occupied by the device, thereby improving the space utilization rate of the device in the factory.

[0021] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0039] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1-10The present invention provides a technical solution: a device for grinding and deburring the surface of die-cast aluminum parts, including a support plate 1, a protective cylinder 4, and two symmetrical clamping mechanisms 3. The protective cylinder 4 is located between the two clamping mechanisms 3 and is fixed to the outer surface of the support plate 1. Both clamping mechanisms 3 are provided with electric rails 2 for lifting and lowering. Both electric rails 2 are fixed to the outer surface of the support plate 1. By controlling the electric rails 2, the clamping mechanisms 3 can be moved up and down.

[0041] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 The clamping mechanism 3 includes a movable seat 301 fixed on the support of the electric track 2. A sleeve 302 is fixed to one end of the movable seat 301 away from the electric track 2. A rotating block 303 is rotatably connected to the inner wall of the sleeve 302. A driving shaft 304 is fixed to the bottom surface of the rotating block 303. A fixed plate 305 is fixed to the bottom end of the driving shaft 304. The outer surface of the fixed plate 305 has four circumferentially arranged square slots 306. Each of the four square slots 306 is provided with a clamping claw 309. A linkage is provided between the four clamping claws 309 and the movable seat 301 to allow the four clamping claws 309 to move simultaneously. The moving assembly has four upper clamping jaws 309 that hold and fix the upper end of the die-cast aluminum part. The electric track 2 drives the clamped die-cast aluminum part to move downward. After the bottom end of the die-cast aluminum part is ground by two retractable grinding machines 605, the bottom end of the die-cast aluminum part will be clamped by the four lower clamping jaws 309. Then, the four upper clamping jaws 309 are controlled to release the upper end of the die-cast aluminum part, so that the lower clamping mechanism 3 clamps and drives the die-cast aluminum part to continue to move downward to complete the subsequent grinding work. This device effectively avoids the problem of the end face of the die-cast aluminum part being difficult to grind by using this staggered clamping method.

[0042] Each of the four square slots 306 has a set of limiting rods 307 fixed to its inner wall. Each set of limiting rods 307 consists of two rods. Each of the four gripping claws 309 has a sliding block 308 fixed to its upper end. The four sets of limiting rods 307 are slidably connected to the four sliding blocks 308 respectively. The setting of the limiting rods 307 increases the stability of the gripping claws 309 when they move and prevents them from moving. One side of the gripping claws 309 is provided with anti-slip texture to increase the friction when the four gripping claws 309 grip the die-cast aluminum parts.

[0043] The linkage component includes a sliding tube 311, which is slidably connected to the outer surface of the drag shaft 304. Four hinge rods 310 are hinged to the bottom of the sliding tube 311. The ends of the four hinge rods 310 away from the sliding tube 311 are respectively hinged to four sliding blocks 308. When the sliding tube 311 moves up and down, the sliding tube 311 will drive the four clamping claws 309 to move closer or further away at the same time through the four hinge rods 310.

[0044] The linkage assembly also includes an electric telescopic rod 313, which is fixed to the movable seat 301. A lever plate 312 is fixed to the telescopic end of the electric telescopic rod 313. A groove 318 adapted to the lever plate 312 is formed on the outer surface of the sliding tube 311. The groove 318 is rotatably connected to the lever plate 312. The clamping mechanism 3 also includes a motor 316, which is fixed to the movable seat 301. A sprocket 317 is fixed to the output end of the motor 316. The outer surface of the drive shaft 304 is fixed... There is a sprocket 315, which is connected to a sprocket 317 via a chain drive. Two limiting slide bars 314 are fixedly connected to the outer surface of the drive shaft 304. Both limiting slide bars 314 are slidably connected to the sliding tube 311. The motor 316 drives the sprocket 317 to rotate. The rotation of the sprocket 317 drives the drive shaft 304 to rotate through the sprocket 315 and the chain. The rotation of the drive shaft 304 will drive the die-cast aluminum part held by the four clamping claws 309 to rotate. The rotation of the die-cast aluminum part facilitates grinding.

[0045] Please refer to this carefully. Figure 7 , Figure 8 , Figure 9 and Figure 10 An auxiliary feeding mechanism 5 is provided above the cavity of the protective cylinder 4. The auxiliary feeding mechanism 5 includes four return plates 507. Limit blocks 509 are fixed to the bottom of each of the four return plates 507. An auxiliary arc plate 508 is fixed above each of the four return plates 507. The protective cylinder 4 includes a sloping inlet fixed above the protective cylinder 4. The four auxiliary arc plates 508 are adapted to the sloping inlet of the protective cylinder 4. Springs are provided inside the protective cylinder 4 to clamp the die-cast aluminum parts with the four return plates 507. When the worker loads the die-cast aluminum part, the part is placed between four return plates 507. Then, the worker presses the part down. The four limit blocks 509 prevent the part from moving further down. At the same time, the four return plates 507 are clamped by the spring pressure of four telescopic springs 512, so that the columnar die-cast aluminum part becomes vertical after being squeezed. This makes it easy for the upper clamping mechanism 3 to clamp and fix the upper end of the part. The worker can perform the clamping work without holding the part by hand.

[0046] Each of the four positioning plates 507 has a long rod 504 fixed to its outer surface. Each of the four long rods 504 has a fixed tube 505 slidably connected to its outer surface. Each of the four fixed tubes 505 is fixedly connected to the inner wall of the protective cylinder 4. Each of the four long rods 504 has a limit block 503 fixed to its outer surface. Each of the four fixed tubes 505 has four slots 506 on its outer surface. Each of the four slots 506 is slidably connected to the four limit blocks 503. The fixed tubes 505 increase the stability of the long rods 504 when they move. The limit blocks 503 slide in the slots 506 to prevent the long rods 504 from rotating in the fixed tubes 505.

[0047] The spring assembly includes an annular plate 501, with four hinge rods 502 hinged to the bottom surface of the annular plate 501. The ends of the four hinge rods 502 away from the annular plate 501 are respectively hinged to four limiting blocks 503. Four fixing rods 510 are fixedly connected to the inner wall of the protective cylinder 4. All four fixing rods 510 are slidably connected to the annular plate 501. Through the hinge between the annular plate 501 and the four hinge rods 502, when the annular plate 501 moves up and down, the four returning plates 507 will be driven to move closer or further apart through the four hinge rods 502.

[0048] The spring assembly also includes four telescopic springs 512, which are respectively sleeved on the outside of four fixed rods 510. The upper ends of the four fixed rods 510 are all fixed with fixed plates 511. The lower ends of the four telescopic springs 512 are all fixed with annular plate 501, and the upper ends of the four telescopic springs 512 are respectively fixed with the four fixed plates 511. The operator inserts the cylindrical die-cast aluminum part from above the protective cylinder 4 between the four return plates 507. The four limit blocks 509 prevent the die-cast aluminum part from moving further down. At this time, the annular plate 501 is subjected to the spring pressure of the four telescopic springs 512 and exerts downward force, causing the annular plate 501 to press the long rod 504 through the hinge rod 502 and move out of the fixed tube 505, causing the four return plates 507 to move towards each other. The four return plates 507 will clamp the bottom end of the die-cast aluminum part.

[0049] The auxiliary feeding mechanism 5 also includes an annular plate 514. Two electric telescopic rods 513 are fixed to the inner wall of the protective cylinder 4. The telescopic ends of the two electric telescopic rods 513 are fixed to the annular plate 514. Four U-shaped top plates 515 arranged in a circular array are fixed to the upper surface of the annular plate 514. Four pressure blocks 516 corresponding to the U-shaped top plates 515 are fixed to the outer surface of the annular plate 501. After the four clamping claws 309 clamp and fix the die-cast aluminum parts, the two electric telescopic rods 513 are first controlled to drive the annular plate 514 to move upward, so that the four return plates 507 move away from each other, so that the limiting block 509 no longer blocks the die-cast aluminum parts.

[0050] Please refer to this carefully. Figure 5 and Figure 6A collection mechanism 6 is provided below the cavity of the protective cylinder 4. The collection mechanism 6 includes a vacuum cleaner 601, which is fixed to the outer surface of the support plate 1. The suction end of the vacuum cleaner 601 is fixedly connected to a first suction port 602. The bottom end of the first suction port 602 is fixedly connected to an annular ventilation pipe 603, which is fixed to the inner wall of the protective cylinder 4. The top of the annular ventilation pipe 603 is fixedly connected to a second suction port 604. The first suction port 602 and the second suction port 604 are connected to each other. Two symmetrical retractable grinding machines 605 are installed between the protective cylinder 4. Both retractable grinding machines 605 are fixed to the inner wall of the protective cylinder 4. During grinding, the grinding force on the die-cast aluminum parts can be controlled by controlling the depth of the two retractable grinding machines 605. Then, the vacuum cleaner 601 is turned on. The dust generated during grinding will be sucked in by the suction port 604 and the retractable grinding machines 605. The splashing dust will be blocked by the protective cylinder 4, effectively intercepting and collecting the generated dust.

[0051] Working principle: During use, the operator inserts the cylindrical die-cast aluminum part between the four return plates 507 from above the protective cylinder 4. The four limit blocks 509 prevent the die-cast aluminum part from moving further down. At this time, the annular plate 501 is subjected to the spring pressure of the four telescopic springs 512, which causes the annular plate 501 to press the long rod 504 through the hinge rod 502 and move out of the fixed tube 505. This causes the four return plates 507 to move towards each other. The four return plates 507 will clamp the bottom end of the die-cast aluminum part, so that the cylindrical die-cast aluminum part is squeezed and becomes vertical, thus completing the feeding work.

[0052] During grinding, firstly, control the two electric telescopic rods 513 to move the annular plate 514 upwards, causing the four return plates 507 to move away from each other, so that the limiting block 509 no longer obstructs the die-cast aluminum part. Then, control the upper clamping mechanism 3 to move the movable seat 301 to drive the actuating plate 312 to press the sliding tube 311 downwards. The downward movement of the sliding tube 311 will cause the four clamping claws 309 to move away from each other through the four hinge rods 310. Control the upper electric track 2 to move the movable seat 301 to move the upper clamping mechanism 3 downwards, so that the four clamping claws 309 can move to the top of the die-cast aluminum part and stop the movement of the movable seat 301. Then, control the electric telescopic rod 313 to drive the actuating plate 312 to pull the sliding tube 311 upwards. 1. The four clamping jaws 309 are brought closer together to clamp the die-cast aluminum part. The motor 316 drives the second sprocket 317 to rotate. The rotation of the second sprocket 317 drives the drive shaft 304 to rotate through the chain and the first sprocket 315. The rotation of the drive shaft 304 drives the die-cast aluminum part clamped by the four clamping jaws 309 to rotate through the fixed plate 305. Then, the clamped die-cast aluminum part is moved downward through the upper electric track 2. The two retractable grinding machines 605 are controlled to fit against the die-cast aluminum part and grind its bottom end. During grinding, the vacuum cleaner 601 is turned on. The generated dust will be sucked in by the second suction port 604 and the retractable grinding machine 605. The splashed dust will be blocked by the protective cylinder 4, effectively intercepting and collecting the generated dust.

[0053] After the bottom end of the die-cast aluminum part is ground by two retractable grinding machines 605, the bottom end of the die-cast aluminum part will be clamped by four clamping jaws 309 below. Then, the four clamping jaws 309 above are controlled to release the upper end of the die-cast aluminum part, so that the clamping mechanism 3 below clamps and drives the die-cast aluminum part to continue to move downward to complete the subsequent grinding work. This device effectively avoids the problem of the end face of the die-cast aluminum part being difficult to grind by using this staggered clamping method. At the same time, the staggered clamping of the upper and lower ends of the die-cast aluminum part does not affect the grinding work, thus improving the efficiency of the grinding work of the die-cast aluminum part.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
