Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a high-efficiency and stable downward pressing structure of a polishing machine grinding head. Background Art

[0002] A polishing machine is a machine that uses a grinding head to perform surface treatment on the surface of a material so that the surface of the workpiece reaches an appropriate roughness.

[0003] The workpiece is placed on a workbench 5 which is slidably connected to a guide rail 6, and then the workbench 5 is driven to move by a power device, and the rotating grinding head causes the moving workpiece to be polished. In the existing plate polishing process, the thickness of various plates is different, so it is necessary to adjust the distance between the grinding head and the workbench. In the existing grinding head lifting equipment, it is generally controlled by a hand-cranked screw. After stopping, the grinding head is lifted and lowered by rotating the screw so that the height of the grinding head reaches the set position. This grinding head height adjustment method has a slow lifting speed and low adjustment efficiency. Utility Model Content

[0004] The utility model aims to provide a polishing machine grinding head high-efficiency and stable pressing structure in view of the defects and shortcomings of the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The utility model discloses a polishing machine grinding head high-efficiency stable downward pressing structure, which comprises a gantry and a turntable rotatably connected to the gantry; the turntable is rotatably connected to the grinding head; the turntable is fixed with a motor for driving the grinding head to rotate;

[0007] A cylinder is connected between the turntable and the gantry; two ends of the cylinder are hinged on the turntable and the gantry respectively.

[0008] Furthermore, rotating frames are fixed on both sides of the gantry; rotating shafts are fixed on both sides of the turntable; the two rotating shafts are rotatably connected to the two rotating frames respectively; two connecting seats are arranged on both sides of the gantry; the two connecting seats are respectively arranged on both sides of the grinding head; the number of the cylinders is two; one end of the cylinder is rotatably connected to the connecting seat; the other end of the cylinder is rotatably connected to the turntable.

[0009] Furthermore, an air intake channel is provided on the turntable; a dust hood is fixed on the top of the turntable; the top of the air intake channel is connected to the dust hood; and the bottom end of the air intake channel is inclined toward one side of the grinding head.

[0010] After adopting the above structure, the utility model has the following beneficial effects: after the workpiece is clamped on the workbench, the linear module connected to the workbench drives the workbench to slide along the length direction of the guide rail, so that the workpiece slides to the bottom of the grinding head; the motor drives the grinding head to rotate, and the surface of the workpiece on the workbench is treated; the cylinder is directly extended and retracted to drive the turntable to rotate, and the height of the grinding head can be adjusted without stopping the machine, and this swing adjustment can be completed by the extension and retraction of the cylinder, and the adjustment efficiency is high. The cylinder, turntable and gantry form a triangular stable support system, which makes the grinding head more stable during the grinding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figures 1 to 4 As shown, the utility model discloses a polishing machine grinding head efficient and stable downward pressing structure, which comprises a gantry 8 and a turntable 1 rotatably connected to the gantry 8; a grinding head 4 is rotatably connected to the turntable 1; a motor for driving the grinding head 4 to rotate is fixed to the turntable 1;

[0019] A cylinder 2 is connected between the turntable 1 and the gantry 8; both ends of the cylinder 2 are hinged to the turntable 1 and the gantry 8 respectively;

[0020] After the workpiece is clamped on the workbench 5, the linear module connected to the workbench 5 drives the workbench 5 to slide along the length direction of the guide rail 6, so that the workpiece slides to the bottom of the grinding head 4;

[0021] The motor drives the grinding head 4 to rotate, and the workpiece on the workbench 5 is surface treated; the cylinder 2 is directly extended and retracted to drive the turntable 1 to rotate, and the height of the grinding head 4 is adjusted without stopping the machine. Moreover, the adjustment of this swinging mode can be completed by the extension and retraction of the cylinder 2, and the adjustment efficiency is high. The cylinder 2, the turntable 1 and the gantry 8 form a triangular stable support system, which makes the grinding head 4 more stable during the grinding process.
