Description

Technical Field

[0001] The utility model relates to the technical field of column movable surface grinders, in particular to an automatic leveling device for column movable surface grinders. Background Art

[0002] A surface grinder is a type of grinder, which mainly uses a grinding wheel to rotate and grind the workpiece to achieve the required flatness. According to the shape of the worktable, it can be divided into two types: a rectangular worktable and a circular worktable. The main parameters of a rectangular worktable surface grinder are the width and length of the worktable, and the main parameter of a circular worktable is the diameter of the worktable surface. According to the type of shaft, it can be divided into horizontal shaft and vertical shaft grinders. There are many types of surface grinders, and a column longitudinal moving surface grinder is one of them.

[0003] During the grinding process, the accuracy of the workpiece depends to a large extent on the horizontal state of the grinder worktable. When the worktable is uneven, it will cause grinding errors, affecting the dimensional accuracy and surface finish of the workpiece. It may cause uneven force on the workpiece during the grinding process, thereby causing deformation and affecting the processing quality. For example, Chinese patent CN 219113600 U discloses a column longitudinally movable surface grinder, including a grinder body, a movable platform and a support frame. A column body is arranged at one end of the grinder body, a grinding head is arranged at one end of the column body, a movable platform is arranged at the top of the grinder body, and a support frame is arranged at the top of the movable platform.

[0004] The above-mentioned column longitudinally movable surface grinder still has certain shortcomings. It filters the dust in the grinding fluid through the filter screen inside the liquid collection box to reduce the internal dust affecting the lubrication and cooling effects when the grinding fluid is pumped out for use again. By spraying the grinding fluid, the grinding fluid can not only play a role in cooling and lubrication, but also play a role in dust removal. In addition, the recycling of the grinding fluid saves resources and has higher applicability. However, when grinding a workpiece, it is necessary to grind multiple different surfaces of the workpiece. After grinding one side of the workpiece, when it needs to grind other sides, the workpiece can only be manually adjusted, resulting in uneven grinding accuracy of the workpiece, affecting the grinding efficiency of the workpiece. Therefore, the present application proposes an automatic leveling device for a column movable surface grinder to solve the above problems. Utility Model Content

[0027] In this example, there are two leveling mechanisms 2, which are symmetrically distributed on the left and right sides with the central axis of the vertical plate 3 as the symmetry line. The workpiece is placed between the two electric clamping devices 207, and then the workpiece is clamped and fixed by the two electric clamping devices 207. The leveling mechanism 2 also includes a receiver fixed on the upper surface of the column movable surface grinder body 1. When the workpiece is fixed, the jacking device 9 is started to drive the support plate 10 to support the workpiece, thereby improving the stability of the workpiece grinding and reducing the force applied to the electric clamping devices 207 on the left and right sides, thereby improving the stability of the device. The service life of the movable seat 202 is extended. An infrared ranging sensor is fixed on the lower surface of the movable seat 202 and located vertically above the receiver.

[0035] (1) When the automatic leveling device of the column movable surface grinder is needed, the workpiece is placed between the two electric clamping devices 207, and then the workpiece is clamped and fixed by the two electric clamping devices 207. After the fixation is completed, the lifting device 9 is started to drive the support plate 10 to support the workpiece, thereby improving the stability of the workpiece grinding and reducing the stress on the left and right electric clamping devices 207. The service life of the device is increased. When the infrared ranging devices on the left and right sides detect different heights, leveling work is required, and leveling can be performed by starting the electric push rods 208 on the left and right sides.

[0036] (2) When the workpiece needs to be polished on the other side after polishing, the left and right motors 201 are started, so that the electric clamping devices 207 on the left and right sides can drive the workpiece to rotate, thereby improving the polishing efficiency. A large amount of debris will be generated during polishing. By starting the fan 403, negative pressure is generated inside the cavity 401, so that the debris is sucked into the cavity 401 by multiple suction heads and isolated by the filter plate 402, so as to facilitate the collection of debris. The debris can be cleaned by opening the maintenance door.
