Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and more specifically, it relates to a deformation-resistant milling fixture for thin-walled sheet metal. Background Technology

[0002] Automotive sheet metal is a thin sheet of metal. When processing sheet metal, it is necessary to perform operations such as shearing, stamping, and grinding. When milling the thin walls of the sheet metal, a milling fixture is required. The sheet metal is mounted on the milling fixture, and then the milling fixture is mounted on a milling machine. The milling cutter on the milling machine mills the edges of the sheet metal to prevent deformation during the milling process.

[0003] According to CN202020332620.6, this utility model discloses a double-sided milling fixture for bar stock, including a spindle housing, a three-jaw chuck, a tool holder carrying an end-face milling cutter, a sliding table with an automatic rotary clamping assembly, and an electric sliding screw pair. The spindle housing contains a drive motor and a transmission component, which works in conjunction with the drive shaft of the three-jaw chuck. The front end of the three-jaw chuck positions and holds the side milling cutter. The sliding table is controlled to move by an electric sliding screw pair fixed within the frame. The lower part... It is also equipped with a dovetail-shaped slider rail assembly. One side of the sliding table is connected to the tool holder of the end face milling cutter via the slider rail assembly, and the other side is fixedly connected to an automatic rotary clamping assembly. The automatic rotary clamping assembly includes a self-locking motor, a clamping rod and a base. The self-locking motor of this bar stock double-sided milling fixture controls the bar stock to remain fixed when milling the side groove. Finally, the bar stock is manually unloaded. It is a multi-purpose machine that can complete end face and side groove milling in one machine, saving time on tool setting and changing machines. It is time-saving, labor-saving, cost-saving and practical.

[0004] Based on the above, existing milling fixtures generally fix sheet metal through a clamping structure. The clamps are generally installed on the upper side of the fixture. Since sheet metal parts are generally large, when the worker places the sheet metal on the upper side of the fixture, the clamps can easily block the sheet metal from being placed on the upper side of the fixture. The sheet metal needs to be aligned on the upper side of the fixture before it can be placed, which affects the efficiency of placing the sheet metal on the fixture. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a deformation-resistant thin-walled sheet metal milling fixture. This solves the problem that existing milling fixtures typically fix sheet metal using a clamping structure, with the clamp usually mounted on the upper side of the fixture. Since sheet metal parts are generally large, when workers place the sheet metal on the upper side of the fixture, the clamp can easily obstruct the placement of the sheet metal, requiring the sheet metal to be aligned on the upper side of the fixture before placement, thus affecting the efficiency of sheet metal placement on the fixture.

[0006] The purpose and effect of this utility model, a deformation-resistant thin-walled sheet metal milling fixture, are achieved by the following specific technical means:

[0007] A deformation-resistant thin-walled sheet metal milling fixture includes a milling body, milling bases, mounting connecting blocks, milling pressure blocks, lower pressure blocks, a sheet metal positioning mechanism, and a sheet metal stabilizing mechanism. Two sets of milling bases are provided, each fixedly connected to the lower sides of the left and right end faces of the milling body. Multiple sets of mounting connecting blocks are provided, each fixedly connected to the lower end faces of the milling body and the two sets of milling bases. Two sets of milling pressure blocks are provided, each with a rotating shaft rotatably connected inside the two sets of milling bases, and the two sets of milling pressure blocks rotate on the left and right sides of the milling body. Two sets of lower pressure blocks are provided, each sliding inside the lower end face of the two sets of milling pressure blocks. The sheet metal positioning mechanism is located inside the milling body. Two sets of sheet metal stabilizing mechanisms are provided, each located inside the two sets of milling pressure blocks.

[0008] Furthermore, the sheet metal positioning mechanism includes a positioning motor and a positioning shaft; the positioning motor is fixedly connected to the middle position inside the milling body; the positioning shaft is rotatably connected to the rear side inside the milling body, and the positioning motor shaft and the positioning shaft are coaxially fixedly connected.

[0009] Furthermore, the sheet metal positioning mechanism also includes: a positioning bevel gear, a power shaft, and a power bevel gear; the positioning bevel gear is coaxially fixedly connected to the rear side of the positioning shaft; there are two sets of power shafts, which are rotatably connected to the left and right sides inside the milling body respectively; there are two sets of power bevel gears, which are coaxially fixedly connected to the inner end faces of the two sets of power shafts respectively, and the two sets of power bevel gears mesh with the positioning bevel gear to form a bevel gear transmission mechanism.

[0010] Furthermore, the sheet metal positioning mechanism also includes: adjusting bevel gears and milling bevel gears; there are two sets of adjusting bevel gears, which are coaxially fixedly connected to the outside of two sets of power shafts, and the two sets of adjusting bevel gears rotate on the left and right sides inside the milling body; there are two sets of milling bevel gears, which are located on the rear side inside the two sets of milling bases, and the two sets of adjusting bevel gears mesh with the two sets of milling bevel gears to form a bevel gear transmission mechanism, and the two sets of milling bevel gears are coaxially fixedly connected to the two sets of milling pressure block shafts.

[0011] Furthermore, the sheet metal stabilizing mechanism includes: a downward pressure screw and a downward pressure lever; the downward pressure screw is threadedly connected to the middle position inside the milling edge pressure block; the downward pressure lever is fixedly connected to the upper end face of the downward pressure screw, and the downward pressure lever rotates to the middle position of the upper end face of the milling edge pressure block.

[0012] Furthermore, the sheet metal stabilizing mechanism also includes: a downward pressing connecting block; the downward pressing connecting block is slidably connected inside the milled edge pressing block, the downward pressing connecting block is fixedly connected to the upper end face of the downward pressing block, and the downward pressing connecting block is rotatably connected to the lower side of the downward pressing screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model employs a sheet metal positioning mechanism to ensure that when the sheet metal is not fixed, the milling edge pressing block is located at both ends of the milling edge main body, and is not located on the upper end of the milling edge main body. When the sheet metal is placed on the upper side of the milling edge main body, the sheet metal part is directly placed on the upper side of the milling edge main body, and the milling edge pressing block does not obstruct the placement of the sheet metal part on the upper side of the milling edge main body. This avoids the problem of workers adjusting the position of the sheet metal part on the milling edge main body, improves the work efficiency of placing the sheet metal part on the upper side of the milling edge main body, and thus improves the efficiency of sheet metal milling of the milling edge fixture. When the milling edge pressing block is fixed to the sheet metal, the positioning motor directly drives the milling edge pressing block to rotate, and the milling edge pressing block fixes the sheet metal.

[0015] This utility model employs a sheet metal stabilizing mechanism. When the sheet metal is not securely fixed after the milling edge block is in place, the operator can manually twist the lower pressure block to rotate and slide it down to press down on the sheet metal. This ensures the stability of the sheet metal during milling and prevents displacement and deformation during milling. Attached Figure Description
