Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, specifically to a surface treatment device for processing castings. Background Technology

[0002] Gear reducers are one of the most commonly used reducers in elevators. The gears inside the reducer are a type of casting, and their upper and lower surfaces need to be ground during the manufacturing process.

[0003] Publication No. CN213765185U discloses a casting grinding device, including a worktable, a base connected above the worktable, a first rotary motor connected inside the base, and a turntable connected above the first rotary motor. This invention uses the first rotary motor, output shaft, turntable, and fixing mechanism to place the casting on top of the turntable. Simultaneously rotating the handwheels on both sides causes the clamping plates on both sides to move towards each other under the connection of the screw holes and screws, thus fixing the casting. Under the action of the first rotary motor, the output shaft and the casting above the turntable rotate at multiple angles. The multi-angle rotation of the casting is facilitated by the connection of the clamping plates and bearings, making the grinding process more flexible and convenient. This solves the problem of high labor intensity and low efficiency when using manual hand-held grinding devices to grind parts or blanks.

[0004] The applicant found some shortcomings in its use: the device clamps and fixes the casting by rotating the screw, but it produces debris during grinding. The debris adheres to the surface of the screw, and rotating the screw can easily cause the screw and the support column to jam. At the same time, since there are no protective measures around the workbench, the grinding debris splashes onto the surrounding ground, increasing the difficulty for workers to clean up.

[0005] Therefore, this utility model designs a surface treatment device for casting processing to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a surface treatment device for processing castings, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for processing castings, comprising: a workbench, a placement tray installed at the top center of the workbench, an L-shaped plate installed at one top end of the workbench, a grinding mechanism provided on the side wall of the L-shaped plate, a clamping mechanism to prevent jamming provided on the top inner wall of the L-shaped plate, support legs installed at the four corners of the bottom of the workbench, and a protective mechanism to reduce debris splashing onto the ground on the workbench.

[0008] Preferably, the clamping mechanism includes a bidirectional lead screw, which is rotatably mounted on the top inner wall of the L-shaped plate. Connecting plates are slidably mounted on both outer walls of the bidirectional lead screw via threads. An electric push rod is mounted at the bottom of the connecting plate, and a mounting block is mounted at the output end of the electric push rod. A rotating shaft is rotatably mounted on the mounting block, and clamping teeth are mounted on the side of the rotating shaft near the placement plate. Rotating the bidirectional lead screw brings the two connecting plates closer together, thereby causing the two clamping teeth to move closer together and clamp the casting. The electric push rod and rotating shaft facilitate the flipping of the casting. The bidirectional lead screw is located above the grinding mechanism, preventing grinding debris from adhering to the bidirectional lead screw and thus avoiding jamming between the bidirectional lead screw and the connecting plate, improving the stability of the clamping mechanism.

[0009] Preferably, a handwheel is installed on one side of the bidirectional lead screw, which facilitates the operator to rotate the two-hand lead screw.

[0010] Preferably, a protective frame is provided at the top perimeter of the workbench, and a square groove is provided on the workbench. The protective frame is slidably installed in the square groove. During grinding, the protective frame is located around the workbench, which can reduce the amount of debris flying off the workbench and falling to the ground, thereby reducing the difficulty for workers to clean up the debris.

[0011] Preferably, a horizontal plate is installed below the two support legs on both sides, and an electric cylinder is installed on the top of the horizontal plate. An installation plate is installed on the output end of the electric cylinder. The installation plate is connected to the bottom middle of the protective frame. The electric cylinder drives the installation plate to descend, causing the protective frame to descend. After the height is reduced, it is easier for workers to clean the workbench.

[0012] Preferably, the L-shaped board is equipped with a PLC controller. The controller is convenient for operators to control.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting up a clamping mechanism, the bidirectional lead screw is positioned above the grinding mechanism, which avoids the situation where debris falls and adheres to the bidirectional lead screw during grinding, thereby preventing the bidirectional lead screw and connecting plate from getting stuck due to debris, and improving the stability of clamping.

[0015] 2. This utility model, through the setting of the protective mechanism, allows the electric cylinder to drive the mounting plate to rise during grinding, thereby raising the protective frame and protecting the top and all sides of the workbench. This reduces the chance of debris flying off the workbench and falling to the ground, and the debris is concentrated and accumulated on the workbench, making it easier for workers to clean and reducing the difficulty of cleaning. When it is necessary to clean the workbench, the protective frame lowers its height to facilitate cleaning by workers. Attached Figure Description

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.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a surface treatment device for casting processing, comprising: a workbench 1, a placement tray 2 installed at the top center of the workbench 1, an L-shaped plate 3 installed at one top end of the workbench 1, a grinding mechanism 4 provided on the side wall of the L-shaped plate 3, a clamping mechanism 5 provided on the top inner wall of the L-shaped plate 3 to prevent jamming, support legs 6 installed at the four corners of the bottom of the workbench 1, a protective mechanism 7 provided on the workbench 1 to reduce debris from falling to the ground, and a guide post installed at the top center of the placement tray. When placing a gear, the round hole in the middle of the gear is aligned with the guide post to guide the gear.

[0023] Please see Figure 1-3 In this embodiment: the grinding mechanism 4 includes a long plate, which is fixed to the side wall of the L-shaped plate. An electric cylinder is installed on the top of the long plate. The output end of the electric cylinder is connected to a grinding motor. The output end of the grinding motor is connected to a grinding disc, which is located directly above the placement disc.

[0024] Please see Figure 3-4In this embodiment: the clamping mechanism 5 includes a bidirectional lead screw 501, which is rotatably mounted on the top inner wall of the L-shaped plate 3. Connecting plates 502 are slidably mounted on both outer walls of the bidirectional lead screw 501 via threads. An electric push rod 503 is mounted on the bottom of the connecting plate 502. An installation block 504 is mounted on the output end of the electric push rod 503. A rotating shaft 505 is rotatably mounted on the mounting block 504. Clamping teeth 506 are mounted on the side of the rotating shaft 505 near the placement plate 2. Two brackets are mounted on the top inner wall of the L-shaped plate. The bidirectional lead screw is rotatably mounted between the two brackets. A guide rod is mounted above the two brackets. The guide rod and the connecting plate are slidably mounted to limit the position of the connecting plate. The side of the rotating shaft away from the clamping teeth is connected to the output end of the servo motor.

[0025] Please see Figure 1 In this embodiment: a handwheel is installed on one side of the bidirectional lead screw 501, and the surface of the handwheel is covered with a cotton layer to improve the comfort of rotation.

[0026] Please see Figure 1-2 In this embodiment: a protective frame 701 is provided at the top four edges of the workbench 1, and a square groove 702 is provided on the workbench 1, with the protective frame 701 slidably installed in the square groove 702.

[0027] Please see Figure 1-2 In this embodiment: a horizontal plate 703 is installed below the two support legs 6 on both sides, an electric cylinder 704 is installed on the top of the horizontal plate 703, an mounting plate 705 is installed at the output end of the electric cylinder 704, and the mounting plate 705 is connected to the bottom middle of the protective frame 701.

[0028] Please see Figure 1 In this implementation: The L-shaped plate 3 is equipped with a PLC controller. The PLC controller and the electrical components used in this equipment are all linearly connected, which facilitates operation by the staff.

[0029] Working principle: The gear is placed on top of the placement plate 2. The electric push rod 503 drives the mounting block 504 to descend, causing the clamping teeth 506 to descend to the middle position of the upper and lower ends of the gear. Then, the double-acting screw 501 is rotated, causing the two connecting plates 502 to move closer together, thus bringing the two clamping teeth 506 closer together to clamp both sides of the gear. Then, the grinding mechanism 4 descends to grind one side of the gear. Subsequently, the electric push rod 503 drives the clamping teeth 506 to rise, causing the gear to rise to a certain distance. The grinding mechanism 4 then rises to its highest position. Then, the rotating shaft 505 drives the gear to rotate 180 degrees. Then, the electric push rod 503 descends again, causing the gear to descend and contact the placement plate 2. The grinding mechanism 4 descends again. The gear can be ground on the other side by lowering it. Because the double-acting lead screw 501 is set at a high position, the grinding debris is less likely to stick to the double-acting lead screw 501, thus avoiding jamming between the double-acting lead screw 501 and the connecting plate 502. During grinding, the electric cylinder 704 drives the mounting plate 705 to rise, which raises the protective frame 701 to protect the top and sides of the worktable 1, reducing the possibility of grinding debris flying out of the worktable 1 and falling to the ground, and reducing the difficulty of cleaning up the debris later. When it is necessary to clean the worktable 1, the electric cylinder 704 drives the protective frame 701 to fall down again, making it easier for the staff to clean. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
