Cabin door structure of surface grinder
Technical Field
The invention belongs to the technical field of machinery, and particularly relates to a cabin door structure of a surface grinder.
Background
The grinding machine is a machine tool for grinding a surface of a workpiece using a grinding tool. Most grinding machines are grinding machines using grinding wheels that rotate at high speeds, and a few are grinding machines using other grinding tools such as whetstones, sanding belts, and free abrasive materials, such as honing machines, superfinishing machines, sanding belt grinding machines, and polishing machines. In order to prevent fragments generated during grinding work from splashing, the grinding machine is mostly provided with a cabin door, and the cabin door on the existing grinding machine is mostly hinged with the machine tool, so that the space occupied during opening and closing is large, and the stability of the cabin door is poor.
For example, chinese patent literature discloses a machine tool protection system for precision grinding machines [ application number: 200910111636.2, a protective cover, a left baffle, a right baffle, a soft cushion, a scraping brush, a lathe bed guide rail protective cover, a screw rod sheath, a wire rail protective cover and a screw rod protective cover are arranged; the protective cover is arranged on the periphery of the grinding machine, the left baffle plate and the right baffle plate are respectively arranged on the left side and the right side of the workbench, the soft cushion is arranged on the left baffle plate, and the scraping brushes are arranged on the side surfaces of the left baffle plate and the right baffle plate; the machine tool body guide rail protective cover is arranged on the machine tool body guide rail of the workbench; the screw rod sheath is arranged at the top end of the upright post screw rod; the wire rail protective cover is arranged on the guide rail of the upright post base, and the screw rod protective cover is arranged on the screw rod of the upright post base.
The above solution improves to some extent some of the problems of the prior art, but it also has at least the following drawbacks: the cabin door occupies large space and has poor stability.
Disclosure of Invention
The invention aims to solve the problems and provide the cabin door structure of the surface grinder, which is small in cabin door occupation space and good in stability.
In order to achieve the above purpose, the present invention adopts the following technical scheme: this plane grinder's hatch door structure, including the cabin that the front end has the opening, the cabin on be equipped with the hatch door, the cabin front end be equipped with two slide rails of vertical setting, hatch door sliding connection in the slide rail, the cabin top side be equipped with the cylinder, the one end fixed connection of the piston rod of cylinder in the hatch door, the other end of cylinder articulate on the positioning seat of hatch door top side, the hatch door outside still be equipped with the shrouding, the shrouding relative cabin fixed connection, shrouding bottom side be located the top of opening bottom side, and both are separated from and form the operation mouth, just the height of operation mouth be not more than the height of hatch door. The cabin door vertically ascends and descends along the opening part through the sliding rail, the operation opening is the position where the cabin door is located when descending, and the cabin door ascends and descends through the air cylinder arranged on the top side of the cabin, so that the working efficiency and stability are improved, the cabin door does not occupy the movable space in the horizontal direction, and the space required by the lowered cabin door when being opened is reduced.
In the cabin door structure of the surface grinder, the cabin door, the sliding rail, the air cylinder and the sealing plate are respectively arranged obliquely relative to the opening part. The operation is convenient, and the head can be prevented from colliding with the sealing plate when the material is taken out of the cabin, so that the safety is improved.
In the cabin door structure of the surface grinder, the top side of the cabin is provided with the erection opening, the rear side of the air cylinder is at least partially positioned in the erection opening, the inner side of the top of the cabin door is provided with the positioning opening, and the front side of the air cylinder is at least partially positioned in the positioning opening. The positioning of the cylinder is realized through the erection opening and the positioning opening, so that the stability of the position of the cylinder is improved, and the lifting unsmooth caused by the deviation of the piston rod is effectively prevented.
In the cabin door structure of the surface grinder, the front end of the positioning seat is provided with a U-shaped opening, and the air cylinder is hinged in the U-shaped opening.
In the cabin door structure of the surface grinder, a plurality of viewing windows communicated with the inner side of the cabin are formed in the cabin door. The grinding condition in the cabin can be observed through the window.
In the cabin door structure of the surface grinder, one side of the sliding rail facing the cabin door is provided with the positioning slide rail with an arc-shaped section, and the inner side of the cabin door is provided with the sliding groove which is arranged corresponding to the positioning slide rail. So that sliding of the hatch can be smoother.
In the cabin door structure of the surface grinder, the number of the air cylinders is one, and one end with a piston rod is fixedly connected to the bottom side of the middle part of the cabin door.
Compared with the prior art, the cabin door structure of the surface grinding machine has the advantages that: the cabin door is simple in structure, the cabin door can be lifted vertically through the air cylinder, stable in lifting and free of occupying space in the horizontal direction when being opened and closed, and in addition, the cabin door is inclined, so that a low-head space can be provided for workers during material taking.
