Description

Technical Field

[0001] This utility model relates to the field of trimming machine technology, and in particular to a workpiece burr removal device. Background Technology

[0002] Burrs refer to the residual chips and extremely fine microscopic particles on the surface of a workpiece generated during machining. The more burrs there are, the lower the quality standard of the workpiece. In modern manufacturing, burrs are mainly removed by grinding and rinsing. Grinding generally requires a lot of manual labor, which is costly and the quality is difficult to guarantee. Rinsing requires the preparation of special rinsing solutions, and drying is necessary after rinsing to prevent corrosion, which is time-consuming and costly.

[0003] Dry ice machines utilize extremely low-temperature dry ice particles, propelled by compressed air, towards the object being processed. This causes the surface dirt to freeze rapidly, becoming brittle and bursting. When the dry ice particles penetrate the cracks in the dirt, they vaporize instantly, expanding nearly 600 times in volume, thus removing the dirt from the object's surface. Using dry ice machines to remove burrs from workpieces offers advantages such as high processing speed and low cost. However, dry ice machines cause a rapid drop in temperature near the workpiece, requiring workers to wear protective gloves. Additionally, the large airflow generated by dry ice machines can cause burrs to fly out, potentially causing injury to the eyes and respiratory system of workers.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a workpiece burr removal device to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention aims to provide a workpiece burr removal device.

[0007] To achieve the above and other related objectives, the technical solution provided by this utility model is as follows: a workpiece burr removal device, including a mounting frame, a dry ice machine mounted on the mounting frame, and a trimming worktable on the top of the mounting frame. The trimming worktable includes a horizontal plate and an arc-shaped plate connected in sequence. A burr collection compartment is provided below the horizontal plate and the arc-shaped plate. The arc-shaped plate has several through holes communicating with the burr collection compartment. Baffles are provided on both sides of the horizontal plate and the arc-shaped plate, with the top of the baffles flush with the top of the arc-shaped plate. The tops of the baffles and the arc-shaped plate are connected by a shield. The arc-shaped plate buffers the airflow emitted by the trimming gun. The through holes on the horizontal plate and the arc-shaped plate collect the removed burrs and guide the vaporized dry ice into the burr collection compartment to prevent burrs from flying out. A turntable that can rotate horizontally is provided on the horizontal plate. A workpiece clamp is provided on the top of the turntable. The turntable is used to fix the workpiece and adjust its angle to avoid frostbite to the operator. An ice outlet pipe is connected to the dry ice machine, and a trimming gun is connected to the ice outlet pipe.

[0008] The preferred technical solution is as follows: a lever is provided on the side of the workpiece fixture away from the arc plate. The lever is used to rotate the turntable to adjust the orientation of the workpiece fixture, which facilitates the cleaning of burrs and avoids the operator from directly contacting the workpiece and causing low-temperature frostbite.

[0009] The preferred technical solution is: the workpiece fixture includes a contour positioning groove, and positioning clamps are provided on both sides of the contour positioning groove to facilitate the picking and placing of the workpiece.

[0010] The preferred technical solution is: the horizontal plate is also provided with through holes that connect to the burr collection compartment, which facilitates the collection of the removed burrs.

[0011] The preferred technical solution is as follows: a burr collection box is also provided inside the burr collection compartment. The burr collection box is detachably installed below the horizontal plate and the curved plate to facilitate the cleaning of the collected burrs.

[0012] The preferred technical solution is: a carbon dioxide exhaust port is provided on one side of the burr collection box to discharge the carbon dioxide deposited in the burr collection box and avoid excessive carbon dioxide concentration in the processing area.

[0013] The preferred technical solution is that the mask is made of transparent material, providing a view of the processing area and facilitating deburring operations.

[0014] The preferred technical solution is: the baffle is provided with a clamp for placing the trimming gun, which facilitates the taking and putting away of the trimming gun.

[0015] Due to the application of the above technical solution, the workpiece burr removal device provided by this utility model has the following advantages compared with the prior art:

[0016] (1) The angle of the workpiece is adjusted by using a turntable and workpiece fixture, which avoids direct contact between the operator and the workpiece and reduces the possibility of frostbite.

[0017] (2) Set up an arc-shaped plate with through holes on the trimming workbench to collect the burrs that fall off, so as to avoid the burrs from accumulating and flying and causing injury to the workers.

[0018] (3) The processing area is shielded and protected by a transparent material shield, while providing a good operating view. Attached Figure Description

[0029] like Figure 1 and Figure 3 As shown, the dry ice machine 1 is located at the lower end of the mounting bracket 100, and an ice outlet pipe 11 is connected to it. A trimming gun 12 is connected to the ice outlet pipe 11.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the trimming workbench 2 is located on the top of the mounting frame 100. The trimming workbench 2 includes a horizontal plate 21 and an arc-shaped plate 22 connected in sequence. Both the horizontal plate 21 and the arc-shaped plate 22 are provided with several through holes that connect to the burr collection compartment 3. Baffles 23 are provided on both sides of the horizontal plate 21 and the arc-shaped plate 22. The top of the baffles 23 is flush with the top of the arc-shaped plate 22. The tops of the baffles 23 and the arc-shaped plate 22 are connected by a transparent material cover plate 24. The baffles 23 are provided with a clamp 23a for placing the trimming gun 12.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, the burr collection compartment 3 is located below the trimming workbench 2. The burr collection compartment 3 is also equipped with a burr collection box 31. The burr collection box 31 is detachably located below the horizontal plate 21 and the arc plate 22. A carbon dioxide exhaust port 31a is provided on one side of the burr collection box 31.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the turntable 4 is rotatably mounted on the horizontal plate 21. The top of the turntable 4 is provided with a workpiece clamp 41, which includes a contour positioning groove 41b and positioning clamping posts 41c on both sides of the contour positioning groove 41b. A lever 41a is provided on the side of the workpiece clamp 41 away from the arc plate 22.

[0033] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the principle and usage of this utility model are as follows: In use, the workpiece is placed in the contour positioning groove 41b and fixed by the positioning clamp 41c; the trimming gun 12 is aligned with the workpiece, and then the dry ice machine 1 is turned on to perform deburring operation. During operation, the angle of the workpiece clamp 41 is adjusted by moving the lever 41a to facilitate comprehensive cleaning of the workpiece; during this process, the dry ice airflow impacts the workpiece, removing the burrs and then impacting the arc plate 22 with the airflow. The airflow and burrs are changed in the conveying direction by the arc plate 22, thereby reducing the flow rate, and the burrs fall into the burr collection box 31 through the through hole. At the same time, the carbon dioxide vaporized by the dry ice also gradually accumulates in the burr collection partition 3. When the burrs are collected to a certain extent, the carbon dioxide in the box is discharged through the carbon dioxide exhaust hole 31a, and then the burr collection box 31 is cleaned.
