[0002] A filter is an accessory that filters impurities or gases through filter paper. Its outer shell is generally cylindrical.

[0003] At present, the filter housing is generally polished by hand, that is, the staff holds the filter housing in one hand and the grinder in the other hand to polish the filter housing. However, in order to prevent the filter housing from shaking when it contacts the high-speed rotating grinding wheel, the staff needs to hold the grinder and the filter housing tightly. Therefore, this polishing method is more laborious and is not conducive to speeding up the polishing efficiency. Utility Model Content

[0006] The utility model is further configured as follows: the control mechanism includes a movable plate, the movable plate is slidably arranged below the working panel, the movable plate is linked with the fixed arm, and the movable plate changes the rotation angle of the fixed arm by sliding up and down.

[0007] The utility model is further configured as follows: a channel is opened on the working panel, the middle part of the fixed arm is rotatably connected to the side wall of the channel, the lower end of the fixed arm extends downward to the bottom of the working panel, and a rocking rod is rotatably provided at the lower end of the fixed arm, and the lower end of the rocking rod is rotatably connected to the upper end of the movable plate.

[0008] The utility model is further configured as follows: a cylinder is fixedly arranged below the working panel, and the cylinder is used for driving the movable plate to move up and down.

[0009] The utility model is further configured as follows: a pulling mechanism is arranged on the working panel, and the pulling mechanism is used to bring the upper ends of all the rocking rods closer together.

[0010] The utility model is further configured as follows: the pulling mechanism includes a tension spring and a connecting block, the number of the tension springs is consistent with the number of the rocking rods and is arranged around the outside of the connecting block, one end of the tension spring is connected to the connecting block and the other end is connected to the upper end of the rocking rod.

[0011] The utility model is further configured as follows: the connecting block is fixedly arranged below the workbench, and the distances between the connecting block and each of the rocking arms are the same.

[0012] In summary, the beneficial effects of the present invention are:

[0013] 1. This structure can achieve the effect of fixing the filter housing by rotating the fixing arm so that the fixing arm is clamped on the side wall of the filter housing.

[0014] 2. When the cylinder pushes the moving plate upward, the tension spring can pull the rocking arm to swing, so that the lower ends of the fixed arms are close to each other, and the upper ends of the fixed arms can be moved away from each other. This method can make the fixed arms smoothly loosen the filter housing.

[0015] 3. The connection blocks are fixedly arranged and have the same spacing as the respective rocking arms, which can ensure that the swing amplitude of the rocking arms is consistent. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the attached embodiment of the utility model Figure 1-2, clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on 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] Example:

[0022] like Figure 1 to Figure 2 As shown, the utility model discloses a fixed table for grinding a filter housing, comprising a working panel 11 and a support column 12 fixedly arranged at the lower end of the working panel 11, a plurality of channels 13 are circumferentially arranged on the working panel 11, the channels 13 penetrate the upper and lower end surfaces of the working panel 11, and a fixed arm 31 is rotatably arranged in each channel 13, the fixed arm 31 is an inverted "L" shape, the middle part of the fixed arm 31 is rotatably connected to the inner side wall of the channel 13, and the lower end of each fixed arm 31 is rotatably connected to a rocking rod 32, a movable plate 33 is slidably arranged up and down below the working panel 11, and the lower end of each rocking rod 32 is rotatably connected to the upper end of the movable plate 33, and a cylinder 34 is fixedly arranged below the working panel 11, and the cylinder 34 is used to drive the movable plate 33 to move up and down.

[0023] A tension spring 35 and a connecting block 36 are also provided under the working panel 11, wherein there is only one connecting block 36, and the number of tension springs 35 is consistent with the number of rocking arms 32 and is circumferentially arranged around the outside of the connecting block 36. In this structure, the two ends of the tension spring 35 are respectively connected to the connecting block 36 and the upper end of the rocking arm 32. At the same time, the connecting block 36 is fixedly arranged under the workbench and has the same spacing as that between each rocking arm 32.

[0024] The working principle of this structure is as follows: when the cylinder 34 moves the moving rod downward, the moving rod will pull the moving rocking arm 32 downward until the rocking arm 32 pulls the fixed arm 31 downward until the side of the fixed arm 31 connected to the rocking arm 32 is in a vertical state. At this time, the upper ends of the fixed arms 31 can be close to each other and thereby clamp the filter housing 2. When the cylinder 34 moves the moving rod upward, the rocking arm 32 performs a directional swing under the action of the tension spring 35. At this time, the upper end of the tension spring 35 will be close to the upper ends of other tension springs 35, that is, the fixed arm 31 and other fixed arms 31 will be in a rocking state with the lower ends close to each other and the upper ends away from each other. At this time, since the upper end of the fixed arm 31 leaves the filter housing 2, the filter housing 2 can be removed from the working panel 11.

[0025] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
