DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0033] like Figures 1 to 4 As shown, a thin plate processing fixture in one embodiment of the present invention includes a base 1, a plurality of blocking mechanisms 2 and at least one pair of clamping mechanisms 3.

[0034] A processing table 101 is connected to the base 1 , and the processing table 101 is used to fix the metal sheet so as to perform subsequent processing on the metal sheet.

[0035] In addition, a cavity 102 is provided within the processing table 101. A plurality of through-holes are provided on the top surface of the processing table 101, and the cavity 102 is connected to the outside world through the through-holes. An exhaust pipe 103 is connected to the processing table 101 and is connected to the cavity 102. The exhaust pipe 103 can be connected to an air suction device. When the air suction device is in operation, the gas in the cavity 102 can be extracted through the exhaust pipe 103, so that the cavity 102 forms a negative pressure state.

[0036] Optionally, the air suction device may be an air compressor.

[0037] Specifically, the bottom wall of the cavity 102 is provided with a plurality of positioning grooves 104, which correspond one to one with the plurality of through holes. The positioning grooves 104 are used to accommodate the bottom rod 201, thereby limiting the blocking mechanism 2 so that the blocking mechanism 2 can be stably installed in the cavity 102.

[0038] In addition, the top wall of the cavity 102 is provided with a plurality of receiving grooves 105, each corresponding to a plurality of through holes. The diameter of the receiving grooves 105 is larger than that of the through holes. The receiving grooves 105 are used to accommodate the sealing gaskets 205, thereby ensuring the sealing effect of the sealing mechanism 2 on the through holes.

[0039] like Figures 1 to 4 As shown, a plurality of blocking mechanisms 2 are respectively arranged in a plurality of through holes, and the blocking mechanisms 2 are used to block the through holes and support the metal sheet.

[0040] The blocking mechanism 2 includes a bottom rod 201, one end of which is disposed in the positioning slot 104. A limit plate 202 is connected to the bottom rod 201. The limit plate 202 has a diameter greater than that of the bottom rod 201 and the protruding rod 203. The limit plate 202 is used to limit the bottom rod 201 so that the bottom rod 201 does not easily slide out of the positioning slot 104.

[0041] In addition, a protruding rod 203 is connected to the limiting plate 202 , one end of the protruding rod 203 passes through the through hole, and the protruding rod 203 is used to contact the metal sheet and is also used to install the clamping mechanism 3 .

[0042] Specifically, a spring 204 is provided on the outside of the bottom rod 201, and the spring 204 is provided between the limit plate 202 and the bottom wall of the cavity 102. Under the action of the spring 204, the limit plate 202 contacts the top wall of the cavity 102, thereby blocking the through hole, so that a negative pressure can be formed in the cavity 102.

[0043] like Figures 1 to 4 As shown, a sealing gasket 205 is connected to the limiting plate 202, and the sealing gasket 205 is engaged in the receiving groove 105. The sealing gasket 205 is made of elastic material. When the limiting plate 202 contacts the top wall of the cavity 102, the sealing gasket 205 is engaged in the receiving groove 105, which is used to increase the sealing effect of the blocking mechanism 2 on the through hole.

[0044] An end of the protruding rod 203 away from the limiting plate 202 is provided with a mounting groove 206 , and the mounting groove 206 is used for mounting the clamping mechanism 3 .

[0045] like Figures 1 to 4 As shown, the clamping mechanism 3 is installed on one of the blocking mechanisms 2, and a pair of clamping mechanisms 3 is used to fix the metal sheet. At the same time, metal sheets of different sizes or shapes can also be fixed, and the scope of application is wide.

[0046] The clamping mechanism 3 includes a mounting rod 301, which is inserted into the mounting groove 206. A first bolt 302 is threadedly connected to the side wall of the protruding rod 203. The first bolt 302 corresponds to the mounting rod 301. The mounting rod 301 is fixed in the mounting groove 206 by the first bolt 302.

[0047] In addition, a clamping plate 303 is slidably provided on the mounting rod 301 , and a second bolt 304 is threadedly connected to the clamping plate 303 , and the second bolt 304 corresponds to the mounting rod 301 . The clamping plate 303 is fixed to the mounting rod 301 by the second bolt 304 .

[0048] Specifically, an elastic pad 305 is installed on the clamping plate 303 to increase the fixing effect of the clamping plate 303 on the metal sheet, so as to fix the metal sheet.

[0049] During specific use, the air suction pipe 103 is connected to an external air suction device, and the air suction device is operated. The air suction device can extract the gas in the cavity 102 through the air suction pipe 103, so that the cavity 102 forms a negative pressure state.

[0050] Place the metal sheet to be processed on several protruding rods 203, press the metal sheet evenly, so that the several protruding rods 203 in contact with the metal sheet move downward in the through hole, the limiting plate 202 will be out of contact with the top wall of the cavity 102, and the sealing gasket 205 will be out of engagement in the receiving groove 105. At this time, the cavity 102 will absorb the metal sheet through the through hole to achieve preliminary fixation of the metal sheet.

[0051] At least one pair of mounting rods 301 are respectively installed in the plurality of mounting slots 206, and the position of the clamping plate 303 on the mounting rods 301 is adjusted so that the elastic pad 305 can contact the metal sheet, thereby achieving the re-fixation of the metal sheet. Figure 1 and Figure 3 The status shown.

[0052] The present invention utilizes adsorption and clamping to achieve stable fixation of the metal sheet without damaging the metal sheet, thereby ensuring the quality of subsequent processing of the metal sheet. Furthermore, since the plurality of blocking mechanisms 2 are evenly distributed on the processing table 101, metal sheets of different sizes or shapes can be fixed, thus having a wide range of applications and reducing processing costs to a certain extent.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
