Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of waste material removal technology, and more specifically to a waste material removal device for die-cast gears. Background Technology
[0002] Die casting produces gears with high precision, capable of producing gears with good dimensional and shape accuracy. The gear's tooth profile, module, and other parameters can be well controlled, ensuring the gear's transmission accuracy and enabling it to withstand large loads. It is suitable for various power transmission systems. Die casting can also manufacture gears with complex shapes, such as gears with irregular tooth profiles or internal tooth structures.
[0003] However, after the gears are die-cast, there is residual material at the edges of the gears. This makes it impossible for the gears to achieve a neat finish. During meshing, this causes accelerated wear between the two gears, which cannot effectively guarantee the service life and efficiency of the gears. Therefore, it is necessary to remove the residual material from the gear surface. Traditional removal devices can only grind the surface of the gear when they use a grinding belt. The residual material between adjacent teeth cannot be effectively ground off, requiring secondary processing. This process is inefficient, time-consuming, and labor-intensive.
[0004] A search revealed that Chinese Patent Publication No. CN202122814394.2 discloses a gear grinding device, comprising a housing and an internal assembly. The inner wall of the housing is fixedly connected to the internal assembly. The internal assembly includes a first motor, with a rotating rod fixedly connected to the top of the first motor via an output shaft. A lower limiting ring is fixedly connected to the outer wall of the rotating rod, and a turntable is fixedly connected to the top of the rotating rod. A fixing buckle is threadedly connected to the top of the turntable. A lower support plate is fixedly connected to the inner wall of the housing, and an upper support plate is fixedly connected to the inner wall of the housing.
[0005] The grinding device in the aforementioned patent places the gear on a turntable when removing residual material, and uses a grinding block to grind one side of the gear. While this method can grind the side of the gear, it cannot effectively grind the residual material between adjacent teeth. Furthermore, it requires stopping the machine when performing flipping grinding, resulting in low work efficiency and an inability to effectively guarantee the quality of residual material removal. Summary of the Invention
[0006] The purpose of this invention is to provide a device for removing excess material from die-cast gears. In this structure, the die-cast gear is placed in a placement cylinder on a turntable. An electric push cylinder drives an L-shaped plate to move downwards, enabling the cover on the output shaft of the first drive motor to engage with the turntable. Simultaneously, the through hole on the cover engages with the gear shaft. The first drive motor enables the turntable to revolve. At the same time, a third drive motor drives a lead screw to rotate, causing a slide plate to move up and down along a guide rod. This allows the third drive motor to drive a grinding wheel to move up and down, effectively removing excess material between the gear teeth. Through the contact between the grinding wheel and the gear, the gear rotates on the placement cylinder, effectively ensuring the removal of excess material from the gear and solving the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A device for removing excess material from die-cast gears includes a worktable; a rotating assembly is fitted on the top of the worktable; the rotating assembly includes a turntable; multiple support sliders are integrally formed on the bottom of the turntable, and the support sliders are L-shaped; the support sliders are slidably connected to an annular slide rail; the annular slide rail is fixedly installed on the top surface of the worktable; and multiple placement cylinders are provided on the side of the turntable away from the support sliders.
[0009] The top surface of the workbench is coaxially provided with a hole to facilitate the passage of the output shaft of the third drive motor.
[0010] As a further technical solution of this utility model, a grinding wheel is provided at the center of the inner layer of the plurality of placement cylinders; the grinding wheel is fixedly connected to the output shaft of the third drive motor by bolts;
[0011] As a further technical solution of this utility model, a lower drive assembly is installed inside the workbench; the lower drive assembly includes a fixed plate; two symmetrically arranged guide rods are fixedly installed between the fixed plate and the bottom of the top surface of the workbench; the guide rods are slidably connected to both sides of the slide plate; one end of the slide plate is threadedly connected to a lead screw; by the slide plate moving up and down along the guide rods, the grinding wheel on the output shaft of the third drive motor repeatedly contacts and rubs along the edge of the gear, thereby effectively removing residual material from the gear;
[0012] As a further technical solution of this utility model, a third drive motor is fixedly installed on the skateboard;
[0013] As a further technical solution of this utility model, one end of the lead screw is fixedly installed with the second drive motor; the second drive motor is fixedly installed at the bottom of the fixed plate;
[0014] As a further technical solution of this utility model, an upper drive assembly is provided on the top of the rotating assembly; the upper drive assembly includes two symmetrical supports; the supports are fixedly installed on the worktable; a top plate is fixedly installed on the end of the supports away from the worktable; an electric push cylinder is fixedly installed on the top plate; the electric push cylinder effectively ensures the cooperation between the cover and the turntable, and ensures the rotation of the turntable driven by the cover, thereby ensuring the quality of removing the gear residue.
[0015] As a further technical solution of this utility model, two symmetrical vertical slide rails are fixedly installed at the bottom of the top plate; one side of the vertical slide rail is slidably connected to the side wall of the L-shaped plate; a first drive motor is also fixedly installed on the L-shaped plate; a cover is fixedly installed on the output shaft of the first drive motor; the cross-section of the cover is L-shaped; a U-shaped opening is provided on the edge of the cover; and the top surface of the cover has the same number of through holes as the placement cylinder; the cover effectively avoids the situation where residual material splashes during the removal of residual material, thus preventing the impact on the surrounding environment.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] In use, the gear is placed on the placement cylinder, and the L-shaped plate is driven to move downward along the vertical slide rail by the electric push cylinder. This causes the first drive motor mounted on the L-shaped plate and the cover on the output shaft to move downward, thus achieving the cooperation between the cover and the turntable. The through hole on the cover cooperates with the shaft at the other end of the gear. The rotation of the first drive motor enables the turntable to revolve.
[0018] In this invention, during the removal of residual material, a second drive motor drives a lead screw to rotate. The lead screw is threadedly connected to the middle of the slide plate, enabling the slide plate to be adjusted up and down. During the adjustment of the slide plate, two guide rods effectively ensure that the third drive motor does not deviate during its movement. Simultaneously, the slide plate drives the third drive motor to move up and down, causing the grinding wheel on the output shaft of the third drive motor to move up and down along the edge of the gear. The rotation of the grinding wheel driven by the third drive motor allows the edge of the grinding wheel to rub against the edge of the gear, thus removing residual material from both sides of the gear. It also enables the gear to rotate within the placement cylinder, thereby effectively improving the quality and efficiency of residual material removal from the gear.
[0019] In this invention, during the removal of residual material, the removal of residual material from the gear is observed through the U-shaped opening on the cover. After the removal is completed, the L-shaped plate is moved upward by the electric push cylinder, so that the cover on the output shaft of the first drive motor is separated from the turntable, and the operator replaces the gear on the placement cylinder.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-7In this embodiment of the present invention, a die-cast gear scrap removal device includes a worktable 1; a rotating assembly 3 is fitted on the top of the worktable 1; the rotating assembly 3 includes a turntable 30; a plurality of support sliders 31 are integrally arranged at the bottom of the turntable 30, and the support sliders 31 are arranged in an L-shape; the support sliders 31 are slidably connected to an annular slide rail 32; the annular slide rail 32 is fixedly installed on the top surface of the worktable 1; a plurality of placement cylinders 33 are arranged on the side of the turntable 30 away from the support sliders 31;
[0030] The top surface of the workbench 1 is coaxially provided with a hole that allows the output shaft of the third drive motor 65 to pass through.
[0031] A grinding wheel 5 is provided at the center of the inner layer of the multiple placement cylinders 33; the grinding wheel 5 is fixedly connected to the output shaft of the third drive motor 65 by bolts.
[0032] By adopting the above technical solution, when in use, the gear 4 is placed on the placement cylinder 33, and the electric push cylinder 22 drives the L-shaped plate 24 to move downward along the vertical slide rail 27, so that the first drive motor 23 installed on the L-shaped plate 24 and the cover 25 on the output shaft move downward, so that the cover 25 cooperates with the turntable 30. The through hole 28 opened on the cover 25 cooperates with the shaft at the other end of the gear 4, and the rotation of the first drive motor 23 realizes the revolution of the turntable 30.
[0033] The workbench 1 is equipped with a lower drive assembly 6; the lower drive assembly 6 includes a fixed plate 61; two symmetrically arranged guide rods 63 are fixedly installed between the fixed plate 61 and the bottom of the top surface of the workbench 1; the guide rods 63 are slidably connected to both sides of the slide plate 64; one end of the slide plate 64 is threadedly connected to the lead screw 62.
[0034] In this embodiment, a third drive motor 65 is fixedly installed on the skateboard 64;
[0035] One end of the lead screw 62 is fixedly installed to the second drive motor 60; the second drive motor 60 is fixedly installed at the bottom of the fixing plate 61;
[0036] By adopting the above technical solution, when removing residual material, the second drive motor 60 drives the lead screw 62 to rotate. The lead screw 62 is threadedly connected to the slide plate 64, realizing the up and down adjustment of the slide plate 64. When the slide plate 64 is adjusted up and down, the two guide rods 63 effectively ensure that the third drive motor 65 will not deviate during the movement. At the same time, the slide plate 64 drives the third drive motor 65 to move up and down, realizing that the grinding wheel 5 on the output shaft of the third drive motor 65 moves up and down along the edge of the gear 4. The third drive motor 65 drives the grinding wheel 5 to rotate, and the edge of the grinding wheel 5 rubs against the edge of the gear 4, which can also realize the removal of residual material on both sides of the gear 4. It can also realize the rotation of the gear 4 in the placement cylinder 33, thereby effectively improving the quality and efficiency of removing residual material from the gear.
[0037] In this embodiment, the top of the rotating component 3 is provided with an upper drive component 2; the upper drive component 2 includes two symmetrical supports 20; the supports 20 are fixedly installed on the worktable 1; a top plate 21 is fixedly installed at the end of the supports 20 away from the worktable 1; an electric push cylinder 22 is fixedly installed on the top plate 21.
[0038] Two symmetrical vertical slide rails 27 are fixedly installed at the bottom of the top plate 21; one side of the vertical slide rail 27 is slidably connected to the side wall of the L-shaped plate 24; a first drive motor 23 is also fixedly installed on the L-shaped plate 24; a cover 25 is fixedly installed on the output shaft of the first drive motor 23; the cross-section of the cover 25 is L-shaped; a U-shaped opening 26 is provided on the edge of the cover 25; and the top surface of the cover 25 has the same number of through holes 28 as the placement cylinder 33.
[0039] By adopting the above technical solution, during the process of removing residual material, the U-shaped opening 26 on the cover 25 is used to observe the removal of residual material from the gear 4. After the removal is completed, the electric push cylinder 22 drives the L-shaped plate 24 to move upward, thereby separating the cover 25 on the output shaft of the first drive motor 23 from the turntable 30. The operator then replaces the gear 4 on the placement cylinder 33.
[0040] The working principle of this utility model is as follows: When in use, the gear 4 is placed on the placement cylinder 33, and the L-shaped plate 24 is driven to move downward along the vertical slide rail 27 by the electric push cylinder 22. This enables the first drive motor 23 installed on the L-shaped plate 24 and the cover 25 on the output shaft to move downward, thereby enabling the cover 25 to cooperate with the turntable 30. The through hole 28 opened on the cover 25 cooperates with the shaft at the other end of the gear 4. The rotation of the first drive motor 23 enables the turntable 30 to revolve.
[0041] During the removal of residual material, the second drive motor 60 drives the lead screw 62 to rotate. The lead screw 62 is threadedly connected to the slide plate 64, which allows the slide plate 64 to be adjusted up and down. During the adjustment of the slide plate 64, the two guide rods 63 effectively ensure that the third drive motor 65 does not deviate during the movement. At the same time, the slide plate 64 drives the third drive motor 65 to move up and down, which allows the grinding wheel 5 on the output shaft of the third drive motor 65 to move up and down along the edge of the gear 4. The third drive motor 65 drives the grinding wheel 5 to rotate, and the edge of the grinding wheel 5 rubs against the edge of the gear 4, which can also remove the residual material on both sides of the gear 4. It can also make the gear 4 rotate in the placement cylinder 33, thereby effectively improving the quality and efficiency of removing residual material from the gear.
[0042] During the process of removing residual material, the removal of residual material from gear 4 is observed through the U-shaped opening 26 on the cover 25. After the removal is completed, the L-shaped plate 24 is moved upward by the electric push cylinder 22, so that the cover 25 on the output shaft of the first drive motor 23 is separated from the turntable 30. The operator then replaces gear 4 on the placement cylinder 33.
