Description

Technical Field

[0001] The invention relates to the field of furniture production, and in particular to a fixture for furniture production. Background Art

[0002] During furniture production, wood needs to be cut, sanded, and polished. The existing fixtures used in furniture production are complicated to disassemble and disassemble, and a lot of time is wasted during the production and processing. In addition, the existing fixtures often cause damage to the boards used in furniture production due to excessive clamping. In addition, during the processing, the wood chips at the bottom of the board cannot be collected in a centralized manner, which brings inconvenience to the cleaning of the factory.

[0003] For this purpose, there is a fixture for furniture production with patent number CN217802199U. While this device solves the above problems, it has the following defects. For example, after the plate is fixed by the L-shaped fixture, the bottom of the plate is in a suspended state. Although it is convenient for chip removal, it is easy to affect its stability, thereby affecting its subsequent processing. When processing each group of plates in the same batch, it is necessary to repeat the operation of four groups of L-shaped fixtures multiple times, which increases labor intensity and affects efficiency.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] A fixture for furniture production, comprising a machine table 1, wherein a groove 2 is arranged on the top of the machine table 1, wherein a collecting hopper 3 extending to the bottom of the machine table 1 is arranged at the bottom of the groove 2, and a dust collecting mechanism 4 is arranged in the collecting hopper 3, a circle of expansion grooves 5 are arranged around the top edge of the groove 2, wherein a grille 6 is arranged in the expansion groove 5, and the top of the grille 6 is flush with the top surface of the machine table 1, a limiting mechanism 7 is arranged on one side of the top of the grille 6, wherein a locking mechanism 8 is arranged on the other side of the top of the grille 6;

[0023] The limiting mechanism 7 includes two groups of limiting plates 71 arranged longitudinally, wherein one end of the limiting plate 71 is provided with a U-shaped notch 72, and the back of the limiting plate 71 on both sides of the U-shaped notch 72 is provided with mounting ears 73, and a clamping plate 74 is also provided in the U-shaped notch 72, wherein one end of the clamping plate 74 extends between the two groups of mounting ears 73, and the two groups of mounting ears 73 are provided with a rotating shaft 75 passing through the clamping plate 74, and one end of the back of the limiting plate 71 is provided with a mounting plate 76 opposite to the clamping plate 74, wherein a convex seat 77 is provided on the top of the machine platform 71 outside the mounting plate 76, and positive and negative screw rods 78 passing through the screw holes on the two groups of mounting plates 76 are provided between the two groups of convex seats 77;

[0024] The locking mechanism 8 includes a locking plate 82 driven by an electric push rod 81 . The locking plate 82 is located between the electric push rod 81 and the limiting plate 1 , wherein the locking plate 82 is arranged parallel to the limiting plate 71 .

[0025] like Figure 1 As shown, the dust collection mechanism 4 includes a motor 41 arranged at the bottom of the collecting hopper 3, wherein the output shaft 42 of the motor 41 extends into the collecting hopper 3, and the output shaft 42 is provided with fan blades 43, and the top of the output shaft 42 is provided with a cross bar 44, wherein the top of the cross bar 44 is provided with bristles 45 that abut against the bottom end surface of the grille 6.

[0026] like Figure 1 As shown, a discharge pipe 9 is provided at the bottom of the collecting hopper 3, wherein a dust removal bag 10 is jacketed on the discharge pipe 9.

[0027] In this embodiment, a slide rod 12 penetrating the mounting plate 76 is arranged between the two groups of bosses 77, wherein the mounting plate 76 is provided with a through hole for the slide rod 12 to pass through, and the forward and reverse screw rods 78 are screwed with the screw holes, wherein a driving block is arranged in the middle of the forward and reverse screw rods 78.

[0028] like Figure 4As shown, a rectangular notch 11 buckled on the U-shaped notch 72 is provided at the top corner of one end of the bottom of the clamping plate 74 , wherein a magnetic connection layer magnetically connected to the limiting plate 71 is provided on the side wall of the rectangular notch 11 .

[0029] When in use, the spacing between the two groups of clamping plates 74 is adjusted according to the length of the plate. The specific steps are to rotate the positive and negative screw rods 78 in the screw holes on the mounting plate 76 and on the bearings on the convex seat 77 to drive the two groups of mounting plates 76 to move, thereby expanding or reducing the spacing between the two groups of mounting plates 76, thereby adjusting the spacing between the two groups of limit plates 71 and the clamping plates 74, so that the spacing between the two groups of clamping plates 74 meets the production requirements;

[0030] Then, the plate is placed on the grille 6 between the two groups of clamping plates 74, with one end of the plate abutting against the limit plate 71, and then the electric push rod 81 drives the locking plate 82 to drive the plate to abut against the limit plate 71, so that the plate is locked and fixed on the limit plate 71 through the locking plate 82, and the front and rear groups of clamping plates 74 can fix the plate to prevent it from moving back and forth for easy processing, wherein the processed debris will fall into the collecting hopper 3 through the holes of the grille 6, or the motor 41 drives the output shaft 42 to drive the fan blades 43 to rotate so that negative pressure is generated in the collecting hopper 3, thereby extracting the debris above the grille 6 and making it enter the collecting hopper 3, and at the same time, the output shaft 42 drives the cross bar 44 and the brush 45 to scrape off the debris that may be adhered to the bottom of the grille 6, and finally the debris and dust in the collecting hopper 3 are forced to be introduced into the dust removal bag 10 for filtration and collection, and the filtered gas is discharged;

[0031] When the plate is removed after processing, the locking mechanism 8 is reset, and the clamping plate 74 is rotated to rotate clockwise with the rotating shaft 75 as the center in the U-shaped notch 72, so that the clamping plate 74 is moved to the back of the limiting plate 71. At this time, the clamping plate 74 does not contact the front and rear ends of the plate, and the plate can be easily removed from the grille 6 without the clamping fixation of the clamping plate 74, and then the clamping plate 74 is reset for the next processing work.

[0032] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
