Description

Technical Field

[0001] The present application relates to the technical field of refrigerator handle processing, and in particular to a deburring device for processing the end surface of a refrigerator handle. Background Art

[0002] At present, refrigerators are widely used in homes and businesses. In foreign countries, they are generally used as Figure 1 The external refrigerator handle 6 shown is in an arc shape, and ports are cut on the two end faces. After the ports are processed, they need to be deburred.

[0003] In the prior art, the refrigerator handle is generally clamped on a tooling, and then a grinding head is driven by a robotic arm to grind along the port. However, since the refrigerator handle is arc-shaped, the existing tooling structure is relatively complex, which makes it inconvenient for workers to place the refrigerator handle, resulting in low production efficiency.

[0004] Therefore, in order to improve production efficiency, it is urgent to improve the existing clamping tooling and use it in conjunction with a robotic arm to improve production efficiency. Utility Model Content

[0005] The purpose of the present application is to provide a deburring device for processing the end surface of a refrigerator handle to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present application provides a deburring device for refrigerator handle end surface processing, which adopts the following technical solution:

[0007] A deburring device for processing the end surface of a refrigerator handle comprises a workbench and a mechanical arm arranged beside the workbench, a grinding motor is installed on the mechanical arm, a grinding head is installed at the output end of the grinding motor, a clamping mechanism for clamping the refrigerator handle is installed on the workbench, the clamping mechanism comprises an electric push rod, a slide seat, a bottom clamping block, a pre-pressing block, a top clamping block and a first cylinder, the electric push rod is fixed on the workbench and used to drive the slide seat to move toward one side of the mechanical arm, the bottom clamping block is fixed on the slide seat, a guide rod is vertically arranged beside the slide seat, and the guide rod is fixed on the slide seat A guide hole is provided on the pre-compression block, and the pre-compression block is movably arranged on the guide rod through the guide hole. An arc groove matched with the outer arc surface of the refrigerator handle is provided on the surface of the bottom clamping block. Pressure rollers are symmetrically connected to the bottom of the pre-compression block on both sides, and the surface of the pressure rollers can abut against the refrigerator handle. A clearance groove and a through hole connected to the clearance groove are provided in the middle of the pre-compression block. A top clamping block is matched in the clearance groove, and a pressure rod connected to the top clamping block is movably arranged in the through hole. The first cylinder is vertically fixed on the slide seat and is used to drive the pressure rod to move up and down.

[0008] Preferably, in order to improve production efficiency, the number of the clamping mechanisms is provided with two, and the two clamping mechanisms are arranged side by side on the workbench, and a screw electric slide module is also provided at the end of the workbench corresponding to the position of the robotic arm, and the robotic arm is fixedly mounted on the slide of the screw electric slide module.

[0009] Preferably, a leveling assembly for leveling the refrigerator handle is also provided on the workbench, and the leveling assembly includes a bracket, a second cylinder and a leveling plate. The bracket is fixed on the workbench, the second cylinder is vertically fixed on the bracket, and the leveling plate is fixed to the end of the piston rod of the second cylinder. The leveling plate can abut against the two side end surfaces of the refrigerator handle.

[0010] By adopting the above technical solution and providing a leveling assembly, when the refrigerator handle is placed on the bottom clamping block, the staff does not need to manually adjust the position of the refrigerator handle. The second cylinder only needs to drive the leveling plate to move downward, and the two ends of the leveling plate are pressed on the refrigerator handle, so that the refrigerator handle can be automatically leveled.

[0013] In summary, the present application includes at least one of the following beneficial technical effects:

[0014] 1. The deburring device for refrigerator handle end surface processing is provided with two clamping mechanisms. When one clamping mechanism is performing deburring, the other clamping mechanism can be loaded and unloaded, so that uninterrupted deburring work can be achieved, thereby greatly improving production efficiency;

[0015] 2. By improving the clamping mechanism, the refrigerator handle is initially fixed by using a pre-pressing block. Pressing rollers are installed on both sides of the bottom of the pre-pressing block, so that the refrigerator handle can be adjusted to ensure that the refrigerator handle is in a horizontal state in the end, and the deburring effect is good;

[0016] 3. By providing a leveling assembly, when the refrigerator handle is placed on the bottom clamping block, the staff does not need to manually adjust the position of the refrigerator handle. The second cylinder only needs to drive the leveling plate to move downward, and the two ends of the leveling plate are pressed on the refrigerator handle, so that the refrigerator handle can be automatically leveled, which not only greatly reduces the labor intensity of the staff, but also improves the positioning accuracy of the refrigerator handle.

[0024] Reference Figure 3-4The clamping mechanism 3 includes an electric push rod 31, a slide 32, a bottom clamping block 33, a pre-pressing block 34, a top clamping block 35 and a first cylinder 36. The electric push rod 31 is fixed on the workbench 1 and is used to drive the slide 32 to move toward the side of the robotic arm 2. The bottom clamping block 33 is fixed on the slide 32. A guide rod 37 is vertically arranged beside the slide 32. The guide rod 37 is fixed on the slide 32. A guide hole is opened on the pre-pressing block 34. The pre-pressing block 34 is movably arranged on the guide rod 37 through the guide hole. The surface of the bottom clamping block 33 is opened with an arc groove that matches the outer arc surface of the refrigerator handle. The surface of the arc groove in the lower clamping block 33 is a smooth surface, and pressure rollers 341 are symmetrically connected to the bottom two sides of the pre-pressing block 34, and the surface of the pressure roller 341 can abut against the refrigerator handle. A clearance groove and a through hole connected to the clearance groove are provided in the middle of the pre-pressing block 34, and a top clamping block 35 is matched in the clearance groove. The bottom end surface of the top clamping block 35 is provided with an arc surface adapted to the refrigerator handle, and the surface of the arc surface is wrapped with a rubber pad, and a pressure rod 38 connected to the top clamping block 35 is movably provided in the through hole, and the first cylinder 36 is vertically fixed on the slide seat 32, and is used to drive the pressure rod 38 to move up and down.

[0025] Reference Figure 2 The workbench 1 is also provided with a leveling assembly 5 for leveling the refrigerator handle.
