Description

Technical Field

[0001] This utility model relates to the field of burr grinding technology for stamped parts, specifically, it demonstrates a device for grinding the edges of stamped parts. Background Technology

[0002] Automotive stamping parts are an indispensable part of automobile manufacturing, belonging to one of the four major processes in automobile manufacturing. Stamping is a highly efficient, low-material-consumption processing method with relatively low operational technical requirements. Specifically, stamping uses a press and dies to apply external force to materials such as sheet metal, strip, tube, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces with specific shapes and sizes. These workpieces are what we call stamping parts. After automotive stamping parts have obtained the required shape and size through the stamping process, they usually need to undergo grinding.

[0003] Currently, after the stamped parts are produced, there will be burrs on the side edges of the stamped parts, which requires the edges to be polished. The current method is to manually control the polishing with a handheld polishing machine, which is not convenient and has low polishing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for the edges of stamped parts, which has a high degree of automation and high grinding efficiency.

[0005] The technical solution is as follows:

[0006] A device for grinding the edges of stamped parts includes a worktable, on which the following are provided:

[0007] A rotating platform with a top-mounted turntable for placing stamped parts, which is rotated 90° by the rotating platform.

[0008] Two grinding groups are arranged diagonally symmetrically on both sides of the rotating platform with the rotation center as the center. Each grinding group includes a grinding machine, a swing seat, a mounting base, and a drive cylinder. The grinding machine is located at one end of the swing seat, the middle part of the swing seat is rotatably located on the mounting base, the tail end of the drive cylinder is rotatably located on the mounting base, and the output head of the drive cylinder is rotatably connected to the other end of the swing seat.

[0009] A lifting platform is located between the grinding assembly and the worktable, and the lifting platform drives the grinding assembly to move vertically upward or downward.

[0010] The rotating platform achieves precise 90° positioning, enabling automatic reversal of the workpiece's four sides, avoiding manual flipping and improving processing efficiency; the symmetrically distributed grinding groups can process two diagonal edges simultaneously, completing 50% of the workload in a single pass; the swing seat and drive cylinder work together to form flexible pressure control, ensuring that the grinding surface of the grinder can stably contact the side edge of the workpiece; the lifting platform enables adaptive adjustment of the grinding height, accommodating workpieces of different heights.

[0011] In addition, the above embodiments of this utility model may also have the following additional technical features:

[0012] According to one embodiment of this utility model, an electric magnetic table is provided on the bearing turntable. Electromagnetic attraction is used to fix the stamping part, effectively securing it and ensuring the normal progress of grinding work, as well as preventing the stamping part from being thrown off when the rotating platform rotates.

[0013] According to one embodiment of this utility model, the grinding working surface of the grinding machine faces inward, and the plane containing the grinding working surface of the grinding machine is perpendicular to the top surface of the bearing turntable. Controlling the grinding angle avoids grinding collapse of the stamped parts' edges, thus preventing damage to the edge perpendicularity. Furthermore, the vertical layout also reduces the direction of grinding debris splashing.

[0014] According to one embodiment of this utility model, the rotating platform is mounted on the worktable via a lateral moving mechanism located between the two grinding groups. The lateral moving mechanism drives the rotating platform to move horizontally. The stamped part is transported to the grinding station via the lateral moving mechanism, and the processing distance is adjusted.

[0015] The worktable surface is equipped with a slotted photoelectric sensor, and the transverse moving end of the transverse moving mechanism is equipped with a trigger end that can be used to trigger the slotted photoelectric sensor. The interaction between the trigger end and the slotted photoelectric sensor causes the stamped part on the rotating platform to move into position.

[0016] According to one embodiment of this utility model, the lifting platform is a Z-axis lead screw motor assembly. The Z-axis lead screw motor assembly has high transmission accuracy, ensuring consistent grinding depth.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: through the composite design of a rotating platform, two grinding groups and a lifting platform, the problems of low efficiency and poor precision of traditional manual grinding are systematically solved, and the four-sided grinding of stamped parts only requires two positioning operations, resulting in high work efficiency.

Detailed Implementation

[0022] 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.

[0023] Reference Figure 1 , Figure 2 , Figure 3 As shown in the figure, this utility model embodiment proposes a stamping edge grinding device, which is mainly for grinding and processing of rectangular stamping parts. The device mainly includes a worktable 1, which is horizontal, and a rotating platform 2, two grinding groups 4 and a lifting platform 5 are installed on the worktable 1.

[0024] The rotating platform 2 is a standard part, such as an existing electric rotary table. A bearing turntable 3 is set on the top of the rotating platform 2. The bearing turntable 3 is usually designed to be circular. The bearing turntable 3 is also horizontal and is used to place the stamping parts to be ground. The rotating platform 2 drives the bearing turntable 3 to rotate 90°, thereby realizing the 90° rotation control of the stamping parts on it.

[0025] In order to further ensure the stability of the stamped parts on the bearing turntable, the stamped parts need to be fixed. One possible implementation is to set an electric magnetic table 6 in the center of the bearing turntable 3. When the electric magnetic table 6 is energized, it can magnetically attract and fix the metal stamped parts. This effectively fixes the stamped parts, ensuring the normal progress of subsequent grinding work. At the same time, it can also prevent the stamped parts from being thrown off the bearing turntable during the rotation of the rotating platform.

[0026] Two grinding groups 4 are arranged diagonally symmetrically on both sides of the rotating platform 2 with the rotation center 2 as the center. That is to say, the two grinding groups 4 can correspond to the two diagonal edges of the stamped parts placed on the bearing turntable 3. After a single processing is completed, the rotating platform 2 controls the stamped parts on the bearing turntable 3 to rotate 90°, and then the two grinding groups 4 grind the other two diagonal edges of the stamped parts. Specifically, the grinding assembly 4 includes a grinding machine 41, a swing seat 42, a mounting base 43, and a drive cylinder 44. The grinding machine 41 is located at one end of the swing seat 42, the middle part of the swing seat 42 is rotatably located on the mounting base 43, the tail end of the drive cylinder 44 is rotatably located on the mounting base 43, and the output head of the drive cylinder 44 is rotatably connected to the other end of the swing seat 42. The drive cylinder 44 controls the rotational swinging motion of the swing seat 42 relative to the mounting base 43, thus realizing the contact grinding operation between the grinding machine and the side edge of the stamped part.

[0027] The lifting platform 5 is located between the grinding assembly 4 and the worktable 1. The lifting platform 5 drives the grinding assembly 4 to move vertically up or down. The lifting platform 5 adopts a Z-axis lead screw motor assembly, which is vertically installed and fixed on the worktable. The Z-axis lead screw motor assembly controls the vertical displacement of the entire grinding assembly relative to the worktable. The Z-axis lead screw motor assembly has high transmission accuracy and accurate movement position, which can ensure the consistency of grinding depth, and the cost is also low.

[0028] It is worth noting that the grinding working surface of the grinding machine 41 should be set to face inward. That is to say, the plane on which the grinding working surface of the grinding machine 41 is located is perpendicular to the top surface of the bearing turntable 3. This ensures that the grinding working surface of the grinding machine can make vertical contact with the part to be ground, which is conducive to controlling the grinding angle and avoiding grinding collapse of the edge of the stamped part, thus preventing damage to the perpendicularity of the edge. Moreover, the vertical layout can also reduce the direction of grinding debris splashing.

[0029] In other embodiments, the rotary platform 2 can be mounted on the worktable 1 via a transverse moving mechanism 7. The transverse moving mechanism 7 is located between the two grinding groups 4, meaning that the straight line extending from the transverse moving mechanism 7 is located on the center line between the two grinding groups 4. The transverse moving mechanism 7 drives the rotary platform 2 to move horizontally. The transverse moving mechanism adopts a standard linear module. The stamped part is transported to the preset grinding station between the two grinding groups through the transverse moving mechanism, which facilitates the adjustment of the processing distance.

[0030] Furthermore, a slotted photoelectric sensor 71 can be provided on the worktable surface 1, and a trigger end 72 for triggering the slotted photoelectric sensor 71 can be provided on the transverse moving end of the transverse moving mechanism 7. The cooperation between the trigger end and the slotted photoelectric sensor enables the stamping part on the rotating platform to move to a preset position.

[0031] The corresponding workflow is as follows:

[0032] The operator places the stamped part roughly in the middle of the surface of the electric magnetic table 6 on the carrier turntable 3, and starts the electric magnetic table 6 to keep the stamped part in a fixed position. The lateral moving mechanism 7 drives the rotating platform 2 to move between the two grinding groups 4, thus transporting the stamped part between the two grinding groups 4. The lifting platform 5 lowers the grinding group 4 to the reference zero point, and the driving cylinder 44 drives the swing seat 42 to rotate and swing, so that the grinding working surface of the grinding machine 41 on the swing seat 42 gradually contacts the side edge of the stamped part and performs the corresponding grinding operation. That is, the two grinding machines 41 simultaneously grind the two diagonal edges of the stamped part. After the processing is completed, the rotating platform 2 rotates 90° clockwise, driving the stamped part to rotate 90°, and the two grinding machines 41 simultaneously grind the other two diagonal edges of the stamped part. After the grinding operation is completed, the stamped part is removed. The above process is repeated.

[0033] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
