Description

Technical Field

[0001] The utility model relates to the field of grinding device protection, in particular to a protection mechanism for a grinding device. Background Art

[0002] The grinding device is a kind of technology that uses a device to modify the surface of a workpiece. It generally refers to a processing method that uses rough objects (sandpaper or grinding wheels containing higher hardness particles, etc.) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness.

[0003] In the prior art, the grinding device is usually composed of: a frame, a workbench, a driving device, a power supply, a grinding wheel, and a clamping fixture. When the workpiece needs to be processed, the workpiece can be placed on the workbench and fixed using the clamping fixture. Then the driving device will start the grinding wheel to rotate and grind the workpiece. However, when the workpiece is in the process of grinding, the grinding debris will fly everywhere, which can easily injure the surrounding workers. In addition, the grinding wheel is usually in a fixed longitudinal or transverse state. The longitudinal grinding wheel can grind the end face of the workpiece, and the transverse grinding wheel can grind both sides of the workpiece. At present, two grinding devices are usually set to grind the end face of the workpiece. During the grinding of the end face or side of the workpiece, manual operation is required to pick up the workpiece and adjust the clamping fixture, which is time-consuming and labor-intensive.

[0004] Therefore, it is necessary to invent a protective mechanism for a grinding device. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protective mechanism for a grinding device, comprising a grinding mechanism and a protective mechanism, wherein the protective mechanism is located outside the grinding mechanism, the protective mechanism comprises a protective shell and a sealing top cover installed on the top of the protective shell, a sealing door is movably hinged on the front of the protective shell, an electric guide rail is installed at the lower end of the inner cavity of the protective shell, the grinding mechanism comprises a workbench and a support plate fixedly installed on one side of the upper end of the workbench, a cross guide rail is installed on the front of the support plate, a first grinding assembly is installed on the cross guide rail, and second grinding assemblies are symmetrically installed on both sides of one end of the workbench close to the support plate.

[0007] Based on the above features: when the sealed door is opened, the electric guide rail can drive the workbench, the support plate, the cross guide rail, the first grinding assembly and the second grinding assembly to move forward and out of the protective shell. At this time, the operator can place the workpiece on the workbench. If the end face of the workpiece needs to be polished, the second grinding assembly can be used to clamp and fix both sides of the workpiece, and then the first grinding assembly can be started to descend to polish the end face of the workpiece. If both sides of the workpiece need to be polished, the first grinding assembly can be used to press the end face of the workpiece, and then the two second grinding assemblies can be started to polish both sides of the workpiece. When the first grinding assembly or the second grinding assembly is polishing the workpiece, the electric guide rail will drive the workbench, the support plate, the cross guide rail, the first grinding assembly and the second grinding assembly to move backward back to the inside of the protective shell to avoid the debris generated during the grinding operation from splashing outward and accidentally injuring the surrounding operators.

[0008] Preferably, an observation glass is provided on the surface of the sealed door.

[0009] Based on the above features: When the workpiece is being ground, the operator can observe through the viewing glass.

[0010] Preferably, a guide slide block is fixedly installed at the bottom of the workbench, and the guide slide block is slidably connected to the electric guide rail.

[0011] Based on the above characteristics: when the electric guide rail is started, the guide slider can drive the workbench, the support plate, the cross guide rail, the first grinding assembly and the second grinding assembly to move forward and backward for adjustment.

[0012] Preferably, the first grinding assembly includes a fixed frame and a grinding motor installed inside the fixed frame, the output end of the grinding motor is connected to a rotating shaft, and a grinding wheel A is installed outside the rotating shaft.

[0013] Based on the above characteristics: the grinding wheel A is in a longitudinal state. When the grinding motor is started, the grinding wheel A can be driven to rotate through the rotating shaft, so that the grinding wheel A can grind the surface of the workpiece conveniently.

[0014] Preferably, the second grinding assembly includes a portal frame and a telescopic cylinder installed inside the portal frame, limit sliders are symmetrically installed at both ends of the telescopic cylinder, a positioning frame is installed at the output end of the telescopic cylinder, and a grinding wheel B is rotatably connected in the middle of the positioning frame.

[0015] Based on the above characteristics: the grinding wheel B is in a horizontal state, and the telescopic cylinder is fixed inside the portal frame. When it is necessary to clamp or grind both sides of the workpiece, the telescopic cylinder will push the positioning frame and the grinding wheel B to move, so that they can fit on both sides of the workpiece according to the size of the workpiece.

[0016] Preferably, a lifting cylinder is installed on the portal frame, a pushing cylinder is installed on one side of the outer end of the portal frame, and limiting sliding grooves are symmetrically provided on the inner walls on both sides of the portal frame, and the limiting sliding grooves are slidably connected to the limiting sliding blocks.

[0017] Based on the above characteristics: the lifting cylinder can drive the telescopic cylinder, the positioning frame and the grinding wheel B to lift and adjust. When the telescopic cylinder is lifted and adjusted, the limit slider will slide and connect to the inner side of the limit slide groove, so that the telescopic cylinder maintains vertical movement, which is convenient for the grinding wheel B to grind the sides of workpieces of different heights, and the pushing cylinder can drive the portal frame to move, which is convenient for the grinding wheel B to grind the sides of workpieces of different lengths.

[0018] Preferably, a groove is provided in the middle of the positioning frame, and a driving motor is installed on the positioning frame.

[0020] The beneficial effects of the utility model are:

[0021] 1. Improve the overall protection. The protective shell and the sealed top cover form a protective box with a door-shaped structure. The rear end of the protective shell is sealed, and the front end of the protective shell is movably sealed by a sealed door. When the sealed door is opened, the electric guide rail can drive the grinding mechanism to move forward and out of the protective shell. At this time, the operator can put the workpiece on the workbench. When the first grinding component or the second grinding component is grinding the workpiece, the electric guide rail will drive the grinding mechanism to move backward back to the protective shell to avoid the debris generated during the grinding operation from splashing outward and accidentally injuring the surrounding operators.

[0022] 2. There is no need to use a clamp to fix the workpiece. The end face or side of the workpiece can be clamped or polished as needed. If the end face of the workpiece needs to be polished, the telescopic cylinder will push the positioning frame and the grinding wheel B to move and fit on both sides of the workpiece. At this time, the drive motor does not need to drive the grinding wheel B to rotate. It only needs to use the grinding wheel B to clamp and fix the two sides of the workpiece. Then start the grinding motor to use the grinding wheel A to polish the end face of the workpiece. If it is necessary to polish both sides of the workpiece, the grinding wheel A can be used to press the end face of the workpiece first, and there is no need to start the grinding motor to drive the grinding wheel A to rotate. The drive motor can drive the grinding wheel B to rotate, which is convenient for the grinding wheel B to polish both sides of the workpiece.
