[0002] Surface grinder is a commonly used metal processing equipment, which is used to perform high-precision grinding on planes and surfaces to improve their surface quality and dimensional accuracy. Since the dust and chips generated by the surface grinder during operation will not only cause harm to the operator, but also pollute the working environment and reduce work efficiency, corresponding dust covers will be installed on the surface grinder. The dust cover can control the diffusion of dust and chips, improve the working environment, and improve the comfort and work efficiency of the operator.

[0003] The opening sizes of the dust covers at both ends of the surface grinders currently on the market are fixed when in use, and the opening sizes cannot be reduced according to actual usage, resulting in dust and chips generated during the operation of the surface grinder to splash out from the larger opening of the dust cover. Therefore, we propose improvements to the existing dust covers for surface grinders. Utility Model Content

[0020] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: a dust cover for a surface grinder, comprising a dust cover body 1, a baffle plate 2 is arranged on the outer side of the opening of the dust cover body 1, and guide seats 3 are arranged on the edges of both ends of the baffle plate 2, and plug-in grooves 4 are opened on the outer side of the guide seat 3, connecting frames 5 are arranged on both sides of the dust cover body 1 close to the baffle plate 2, and a movable groove 6 is opened inside the connecting frame 5, the guide seat 3 is docked and plugged into the inside of the movable groove 6, a guide column 7 is penetrated in the middle of the guide seat 3, and a first spring 8 is sleeved on the outer side of the guide column 7.

[0023] One end of the first spring 8 is connected to the inner wall of the movable groove 6, and the other end of the first spring 8 is connected to the guide seat 3; a mounting groove 9 is opened on the inner side of the connecting frame 5 close to the movable groove 6, and a plug pin 10 runs through the inside of the mounting groove 9, and a second spring 11 is sleeved on the outer side of the plug pin 10; the two ends of the second spring 11 are respectively connected to the plug pin 10 and the mounting groove 9, and the outer end of the plug pin 10 is connected to a connecting strip 12, and the mounting grooves 9 are distributed at equal intervals. The plug pin 10 forms a telescopic structure with the mounting groove 9 through the second spring 11, and the guide seat 3 and the movable groove 6 are slidably connected.

[0024] During specific implementation, the shielding plate 2 in the initial state is overlapped with the open end of the dust cover body 1. According to actual use, the connecting strip 12 is pulled outward, and the pulled connecting strip 12 drives the connected plug pin 10 to move synchronously outward along the inside of the installation groove 9, and the second spring 11 sleeved on the outside is squeezed by the plug pin 10 moving outward until the connecting strip 12 is pulled outward to the limit position. At this time, the plug pin 10 and the plug slot 4 are separated, and the shielding plate 2 is immediately pushed upward, and the pushed shielding plate 2 moves stably along the guide column 7 inside the movable groove 6 through the guide seats 3 at both ends, and the first spring 8 sleeved on the outside of the guide column 7 is squeezed by the moving guide seat 3 until the shielding plate is 2 is pushed upward to the required position according to actual usage, and the guide seat 3 is made to correspond to the plug pin 10 at the same height, and then the pulled connecting strip 12 is loosened. The loosened connecting strip 12 drives the plug pin 10 to automatically reset inward through the elastic force of the second spring 11, so that the plug pin 10 at the same horizontal position as the guide seat 3 is docked with the plug slot 4, and the baffle plate 2 can be limited. By arranging a baffle plate 2 that can be moved up and down on the outside of the dust cover main body 1, the opening size of the dust cover main body 1 can be adjusted according to actual usage, and the gap between the dust cover main body 1 and the surface grinder can be reduced, so that the dust cover for the surface grinder can reduce the spread of dust and chips outward.

[0025] Embodiment 2

[0026] See also Figure 1 and Figure 2 On the basis of the first embodiment, a fixing seat 13 is arranged above one end of the dust cover body 1, and a limiting seat 14 is arranged above the other end of the dust cover body 1, and a connecting plate 15 is connected to the upper end of the fixing seat 13; a mounting frame 16 is arranged above the end of the connecting plate 15 away from the fixing seat 13, and a threaded pin 17 passes through the middle of the mounting frame 16; a limiting rod 18 is connected to the bottom of the threaded pin 17, and a limiting hole 19 is provided inside the limiting seat 14, the threaded pin 17 and the mounting frame 16 are threadedly connected, and the limiting rod 18 and the limiting hole 19 are plug-connected.

[0027] During the specific implementation, the threaded pin 17 is first screwed upward to the extreme position, so that the threaded pin 17 drives the limit rod 18 connected to the bottom to move upward, and then the two ends of the accordion-style dust cover main body 1 are pressed inward and contracted at the same time, until the limit hole 19 is pressed to correspond to the bottom of the limit rod 18, and then the threaded pin 17 is screwed downward, and the threaded pin 17 that is screwed downward drives the limit rod 18 to move downward synchronously until the limit rod 18 is inserted into the inside of the limit hole 19, so that the pressed and contracted dust cover main body 1 can be limited, and the contracted dust cover main body 1 can be limited by the mutual cooperation between the limit rod 18 and the limit hole 19 that move up and down, so that the dust cover main body 1 has an anti-scattering function.

[0028] In actual use, since the surface grinder generates dust and chips during operation, it is necessary to use a dust cover body 1 to control the diffusion of dust and chips. First, the dust cover body 1 is installed above the dust cover body 1 in use, and the shielding plate 2 on the outside of the dust cover body 1 is adjusted up and down to the required position according to the actual use situation to reduce the gap between the dust cover body 1 and the surface grinder, so that the dust cover for the surface grinder can reduce the diffusion of dust and chips outward.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
