Description

Technical Field

[0001] The utility model relates to the technical field of surface grinders, in particular to an auxiliary loading and unloading mechanism for surface grinders. Background Art

[0002] A surface grinder is a type of grinder. It mainly uses a grinding wheel to rotate and grind the workpiece to achieve the required flatness. According to the shape of the workbench, it can be divided into two types: rectangular workbench and circular workbench. The main parameters of a rectangular workbench surface grinder are the width and length of the workbench, and the main parameter of a circular workbench is the diameter of the workbench surface. In the prior art, the unloading of a surface grinder is generally completed by a dedicated robotic arm. This method requires the installation of more external equipment and has a higher cost.

[0003] For example, Chinese patent announcement No. CN216265357U discloses a loading and unloading auxiliary mechanism for a surface grinder. When in use, the first driving motor drives the support table to rotate. It should be noted that the support table does not rotate around its geometric center, but around the eccentricity, so as to ensure that it can be transferred to other horizontal positions after rotation, otherwise it can only rotate in situ. The first swing arm and the second swing arm rotate around the hinge point in the long through hole respectively. When they rotate outward and unfold, the first swing arm and the second swing arm can support the workpiece on the surface of the support table; and when the first swing arm and the second swing arm are retracted inward, the workpiece can be put down. Before the first swing arm and the second swing arm are opened, the pallet rises to the bottom of the discharge port through the scissor-type lifting rod; when the first swing arm and the second swing arm are opened, the workpiece can fall from the discharge port to the pallet.

[0004] However, the loading and unloading auxiliary mechanism of the surface grinder in the above application requires workers to carry the workpiece onto the supporting table when facing heavier workpieces, which consumes the workers' physical strength, and no corresponding fixing mechanism is set during processing. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide an auxiliary loading and unloading mechanism for surface grinders. Utility Model Content

[0006] The purpose of the utility model is to provide an auxiliary loading and unloading mechanism for a surface grinder to solve the problem that the auxiliary loading and unloading mechanism for a surface grinder proposed in the above background technology requires workers to carry the workpiece onto a supporting table when facing a heavier workpiece, which consumes the workers' physical strength, and no corresponding fixing mechanism is set during processing.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary loading and unloading mechanism for a surface grinder, comprising a processing table and a loading box, the loading box being installed on the right side of the processing table, a loading device being arranged inside the loading box, and a feeding device being arranged on the upper surface of the processing table.

[0008] The feeding device comprises a feeding unit and a pushing unit.

[0009] The feeding unit includes a feeding motor, a transmission member, a connecting rod, and a feeding plate. The feeding motor is installed on the feeding box, the transmission member is connected to the output end of the feeding motor, the connecting rod is fixedly connected to the front end of the transmission member, and the feeding plate is fixedly connected to the front end of the connecting rod.

[0010] A further improvement is that a limiting slot is provided on the back of the feeding box, the transmission member is installed inside the limiting slot, the connecting rod is slidably connected to the inner wall of the limiting slot, the workpiece is placed on the feeding plate inside the feeding box, and then the feeding motor is started to drive the screw in the transmission member to rotate, thereby driving the threaded sleeve on the screw and the connecting rod at its front end to slide upward along the inner wall of the limiting slot, thereby driving the workpiece on the feeding plate to rise.

[0011] A further improvement is that the pushing unit includes a mounting table, a pushing cylinder, and a pushing plate. The mounting table is fixedly connected to the right side of the loading box, the pushing cylinder is installed on the mounting table, and the pushing plate is fixedly connected to the left end of the pushing cylinder. When the workpiece rises, the pushing cylinder is started to push the pushing plate to the left, thereby pushing the workpiece on the loading plate to the processing table for subsequent grinding and processing. No manual loading is required, saving time and effort.

[0012] A further improvement is that the feeding device comprises a feeding unit and a unloading unit.

[0013] The feeding unit includes an electric guide rail, a guide rail seat, a supporting platform, and a clamping assembly. The two electric guide rails are respectively installed on the front and rear sides of the upper surface of the processing table. The two groups of guide rail seats are respectively slidably connected to the electric guide rails. The supporting platform is fixedly connected to the top of the guide rail seat. The two groups of clamping assemblies are respectively installed on the front and rear sides of the upper surface of the processing table.

[0014] A further improvement is that the clamping assembly includes a clamping cylinder and a clamping plate, the clamping cylinder is installed at the front end of the upper surface of the processing table, and the clamping plate is fixedly connected to the outer end of the clamping cylinder, driving the guide rail seat to slide to the left on the electric guide rail, thereby driving the workpiece on the supporting platform on the top of the guide rail seat to move to the left for feeding processing. When the workpiece moves to the bottom of the grinding assembly, the two clamping cylinders are started synchronously to drive the clamping plates to move relative to each other, thereby clamping and fixing the workpiece to avoid displacement of the workpiece during grinding.

[0015] A further improvement is that the unloading unit includes a unloading cylinder, a unloading push plate, a unloading slide plate, and a material receiving box. The unloading cylinder is installed on the left side of the upper surface of the processing table, the unloading push plate is fixedly connected to the back of the unloading cylinder, the unloading slide plate is fixedly connected to the left side of the back of the upper surface of the processing table, and the material receiving box is placed on the left side of the back of the processing table. After the workpiece is polished, the guide rail seat continues to be driven to move left. After the workpiece moves to the left side of the processing table, the unloading cylinder is started to push the unloading push plate to move backward, thereby pushing the workpiece on the load table to the unloading slide plate to slide up and down to the inside of the material receiving box. No manpower is required for unloading, which is safer and faster.

[0016] A further improvement is that a grinding assembly is installed on the right side of the rear of the processing table, and the workpiece is ground by the grinding assembly.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1.

[0019] 2. The auxiliary loading and unloading mechanism for the surface grinder drives the guide rail seat to slide to the left on the electric guide rail, thereby driving the workpiece on the bearing platform on the top of the guide rail seat to move to the left for feeding and processing. When the workpiece moves to the bottom of the grinding assembly, the two clamping cylinders are started synchronously to drive the clamping plates to move relative to each other, thereby clamping and fixing the workpiece to avoid displacement of the workpiece during grinding.

[0020] 3. This auxiliary loading and unloading mechanism for surface grinders continues to drive the guide rail seat to move left after the workpiece is ground. When the workpiece moves to the left side of the processing table, the unloading cylinder is started to push the unloading push plate to move backward, thereby pushing the workpiece on the load-bearing table to the unloading slide plate to slide up and down to the inside of the material receiving box. No manpower is required for unloading, which is safer and faster. BRIEF DESCRIPTION OF THE DRAWINGS
