DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0022] This embodiment mainly describes the structure of the clamping device for fine machining of the aluminum shell of the gas meter, as follows:

[0023] A clamping device for finishing the aluminum shell of a gas meter, such as Figure 1-Figure 4 As shown, it includes a base 1, a protective shell 201, a guide rail 202, a cylinder 203, a clamping assembly 2 and a gear 209. A square groove is provided on the top of the base 1, and the protective shell 201 is fixedly connected in the square groove of the base 1. The guide rail 202 is fixedly connected to the protective shell 201, and the cylinder 203 is fixedly connected to the protective shell 201. The bottom of the protective shell 201 is rotatably connected to the gear 209, and the guide rail 202 is connected to the clamping assembly 2. The clamping assembly 2 is provided with two groups, which are respectively located at the front and rear ends of the guide rail 202; the clamping assembly 2 includes: a slider 204, a pushing block 205, a clamping block 206, a sliding block 207 and a rack 208. The guide rail 202 is slidably connected to the slider 204, and the slider 204 is fixedly connected to the pushing block 20 5. The telescopic rod on the cylinder 203 is fixedly connected to the pushing block 205 of one group of the clamping assemblies 2. The pushing block 205 is slidably connected with a clamping block 206. The clamping block 206 is in the shape of a semi-cylinder. The clamping block 206 is used to contact with the aluminum shell and adjust the position following the surface of the aluminum shell. Two clamping blocks 206 form a group. Each clamping block 206 is provided with a group of clamping blocks 206 to form a hierarchical progression. In this way, there are four levels. A sliding block 207 is fixedly connected to the slider 204. A sliding groove is provided on the protective shell 201. The sliding block 207 is slidably connected in the sliding groove. A rack 208 is fixedly connected to the bottom of the sliding block 207. The rack 208 is located in the protected shell 201. The racks 208 of the two groups of clamping assemblies 2 are meshed with the gear 209.

[0024] When the operator uses the clamping device, first, the aluminum shell to be clamped is placed on the guide rail 202, and then the cylinder 203 is started. The telescopic rod of the cylinder 203 will push the rear clamping assembly 2 to slide forward, so the pushing block 205 will drive the slider 204 and the sliding block 207 to move forward synchronously, and the sliding block 207 will also drive the rack 208 to move forward synchronously. During the movement of the rack 208, the meshing action of the rack 208 and the gear 209 controls the rotation of the gear 209 and drives the other rack 208 to move in the opposite direction, that is, drives the clamping assembly 2 on the front side to move in the opposite direction, that is, to move backward, so the clamping assemblies 2 on both sides move closer to the center to clamp the aluminum shell. During the clamping process, the clamping block 206 will be adjusted according to the surface shape of the aluminum shell, so that the clamping block 206 is more in line with the surface of the aluminum shell, thereby improving the stability of the clamping device in clamping and fixing the aluminum shell.

[0025] like Figure 1 As shown, it also includes an air blower 3, a fixed frame 4 and a collection box 5. A slide groove is provided on the right side of the base 1, and the air blower 3 for blowing away debris is slidably connected to the slide groove of the base 1. The fixed frame 4 is fixedly connected to the left side of the base 1, and the collection box 5 for collecting debris is fixedly connected to the bottom of the fixed frame 4.

[0026] After the aluminum shell is fixed, a large amount of debris will be generated on the desktop during the milling process of the aluminum shell. The staff uses the blower 3 to slide the blower 3 on the front side of the base 1 to blow the debris on the desktop into the fixing frame 4. The debris will fall into the collection box 5, so that the debris can be collected and cleaned up conveniently.

[0027] like Figure 1 As shown, it also includes a hook 6, and the front side of the base 1 is fixedly connected with a hook 6 for hanging operating gloves.

[0028] When the staff does not need to use gloves, the hook 6 can be used and can be freely taken, thus saving time.

[0029] It also includes a placement block 7, and the base 1 is fixedly connected with the placement block 7 for placing the aluminum shell.

[0030] The aluminum shell is placed upside down on the placement block 7 to make the position of the aluminum shell more stable, prevent the aluminum shell from falling off the base 1 and causing bumps, and improve the safety of the aluminum shell.

[0031] like Figure 1 As shown, it also includes a shielding plate 8. The front and rear sides of the sliding block 207 are fixedly connected with the shielding plate 8. The protective shell 201 is slidably connected to the shielding plate 8. The shielding plate 8 is used to close the sliding groove on the protective shell 201.

[0032] When the clamping assembly 2 moves, it will drive the shielding plate 8 to slide synchronously to prevent debris from passing through the slide groove and falling into the protective shell 201, avoiding affecting the operation of the internal rack 208 and gear 209, thereby improving the safety when using the clamping device.

[0033] like Figure 1 As shown, a friction plate 9 is also included. The guide rail 202 is fixedly connected with the friction plate 9 for increasing the friction force when the aluminum shell is placed.

[0034] When placing the aluminum shell on the guide rail 202, the aluminum shell should be placed on the friction plate 9. The friction plate 9 plays a positioning role to prevent the aluminum shell from being displaced during the clamping process, so that the aluminum shell can be clamped more stably.

[0035] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use.

This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the utility model and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
