Description

Technical Field

[0001] This utility model relates to the field of grinding production equipment technology, specifically a sheet metal grinding device. Background Technology

[0002] After stamping, bending, and other forming processes, sheet metal parts often have burrs, oxide layers, or uneven areas on their edges or surfaces, requiring grinding to meet assembly accuracy and appearance quality requirements. Currently, the industry relies heavily on manual operation of handheld grinders or angle grinders for grinding small batches of sheet metal parts. This method is not only labor-intensive and inefficient, but the grinding quality also heavily depends on the operator's experience, resulting in poor product consistency and difficulty in guaranteeing precision.

The lower ends of the two pairs of suction pipes are connected to the high-pressure vacuum pump. The mounting bracket is located in the second support platform and can be raised and lowered relative to the second support platform.

[0004] Preferably, the lifting and adjusting assembly includes: a support frame, a pair of second hydraulic cylinders, and a lifting plate; The support frame is installed in the middle of the rear of the grinding mounting platform wall.

Detailed Implementation

[0013] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] Example: Please refer to Figure 1-2 The main components of this technical solution are: a grinding mounting table 1, on which a pneumatic fixed and rotating grinding structure is installed; The pneumatic fixed-rotary grinding structure includes: a fixed component, a lifting and adjusting component, and a rotary grinding component; The fixed component is installed on the upper wall of the grinding mounting table 1, the lifting and adjusting component is installed behind the fixed component, and the rotary grinding component is installed on the lifting and adjusting component; The fixed components include: a first support platform 2, a pair of second support platforms 3, four pairs of first hydraulic cylinders 4, two pairs of mounting brackets 5, two pairs of suction heads 6, two pairs of suction pipes 7, and a high-pressure vacuum pump 8. The first support platform 2 is installed in the middle of the upper wall of the grinding mounting platform 1. A pair of second support platforms 3 are installed on both sides of the first support platform 2. Four pairs of first hydraulic cylinders 4 are installed in front of and behind the pair of second support platforms 3. Two pairs of mounting brackets 5 are installed on the upper ends of the four pairs of first hydraulic cylinders 4. Two pairs of suction heads 6 are embedded in the two pairs of mounting brackets 5. The upper ends of two pairs of suction pipes 7 are installed on the two pairs of suction heads 6. The high-pressure vacuum pump 8 is fixedly installed in the middle of the lower wall of the grinding mounting platform 1. The lower ends of the two pairs of suction pipes 7 are connected to the high-pressure vacuum pump 8. The mounting brackets 5 are located in the second support platform and can be raised and lowered relative to the second support platform 3.

[0015] It should be noted that when using the fixing components, the sheet metal parts are placed on the first support platform 2 and the second support platform 3. The equipment is powered on and started by operating the controller that matches the equipment. The high-pressure air pump 8 installed on the lower wall of the grinding mounting platform 1 is started to extract air. Air is extracted from the suction head 6 through the suction pipe 7. The output end of the first hydraulic cylinder 4 extends upward and drives the suction head 6 to suck up the workpiece to fix the workpiece and prevent it from moving.

[0016] In the specific implementation process, the lifting and adjusting assembly further includes: a support frame 9, a pair of second hydraulic cylinders 10, and a lifting plate 11; The support frame 9 is installed at the rear center of the upper wall of the grinding mounting table 1. A pair of second hydraulic cylinders 10 are installed on both sides of the lower inner wall of the support frame 9. The lifting plate 11 is installed on the output end of the pair of second hydraulic cylinders 10.

[0017] It should be noted that when using the lifting and adjusting assembly, the first hydraulic cylinder 4 installed on the support frame 9 extends downward from its output end, and the first hydraulic cylinder 4 drives the lifting plate 11 to move downward to adjust the grinding and processing height.

[0018] In the specific implementation process, the rotary grinding assembly further includes: a rotary drive motor 12, a rotary shaft 13, a grinding disc 14, an annular fixed slide rail 15, and a pair of fixed support rods 16; The rotary drive motor 12 is installed in the middle of the upper wall of the lifting plate 11. The upper end of the rotating shaft 13 passes through the lifting plate 11 and is installed on the output end of the rotary drive motor 12. The grinding disc 14 is installed at the lower end of the rotating shaft 13. The annular fixed slide rail 15 is installed on the lower wall of the lifting plate 11. The lower ends of a pair of fixed support rods 16 are installed on the upper wall of the grinding disc 14, and the upper ends of the pair of fixed support rods 16 are embedded in the annular fixed slide rail 15.

[0019] Preferably, when the cylinder rod of the first hydraulic cylinder 4 is pushed up to its maximum stroke, the top surface of the suction head is higher than the top surface of the second support platform. The first hydraulic cylinder is a multi-position cylinder with three stroke positions: retracted, neutral, and extended. When the cylinder rod of the first hydraulic cylinder retracts to the retracted position, the top surface of the suction head is lower than the top surface of the second support platform, thus allowing the suction head to avoid the sheet metal parts being loaded. After the sheet metal parts are placed on the second support platform 3, the cylinder rod of the first hydraulic cylinder 4 is pushed up to the neutral position. The top of the suction head 6 first presses against the bottom surface of the sheet metal parts, and then rises slightly as the suction head 6 continues to rise. Because the top of the suction head 6 is made of flexible material, it is slightly compressed under the pressure of the sheet metal parts, which helps the suction head 6 to adhere tightly to the sheet metal parts. After grinding, when the cylinder rod of the first hydraulic cylinder is pushed up to the extended position (i.e., pushed up to its maximum stroke), the suction head lifts the sheet metal parts, causing the sheet metal parts to be separated from the second support platform 3 and the first support platform 2 by a certain distance. This distance allows the forks of forklifts and other handling tools to extend, thus facilitating the unloading of the processed sheet metal parts.

[0020] It should be noted that when using the grinding assembly, the rotary drive motor 12 installed on the lifting plate 11 starts to rotate. The rotation of the rotary drive motor 12 drives the rotary shaft 13 connected to its output end through the coupling 19 to rotate. The rotation of the rotary shaft 13 drives the grinding disc 14 installed at its lower end to rotate for grinding. At the same time as grinding, a pair of fixed support rods 16 installed on the grinding disc 14 and whose other ends are embedded in the annular fixed slide rail 15 start to support and fix the grinding disc 14.

[0021] In the specific implementation process, furthermore, the grinding and mounting table 1 is equipped with support legs 17 that have a supporting function.

[0022] In the specific implementation process, a motor frame 18 with a fixing function is further installed on the rotary drive motor 12, and the motor frame 18 is fixedly connected to the lifting plate 11.

[0023] In the specific implementation process, the rotating shaft 13 is further mounted on the rotary drive motor 12 via the coupling 19.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
