Description

Technical Field

[0001] The utility model belongs to the technical field of wood processing, and particularly relates to a fixture with a chuck that is easy to disassemble. Background Art

[0002] A patent with publication number CN217434281U discloses a square fixture for wood processing, which relates to the technical field of wood processing and includes a chassis. A positioning bent plate is fixedly installed on the upper surface of the chassis. For this square fixture for wood processing, when the telescopic end of the first electric push rod retracts, the sliding frame is pulled to move leftward under the guidance of the guide rail, driving the moving bent plate to be adjusted leftward, which is more suitable for using wood blocks of different lengths. Through the telescopic movement of the telescopic end of the second electric push rod, the moving bent plate can be driven to adjust its front-back position under the guidance of the guide posts and guide sleeves, which is more suitable for using wood blocks of different widths. When the moving bent plate is adjusted to be close to the right front corner of the wood block body, the positioning and pressing of the wood block body are completed. And during the positioning and pressing, the inner sides of the moving bent plate and the positioning bent plate are in contact interference with the four sides of the wood block body, thus avoiding the problem of the wood block body moving during processing.

[0003] The structure of this utility model is relatively precise, with high cost and not easy to use for a long time, and there is a lack of clamping in the vertical direction, and the workpiece will still shift. Summary of the Utility Model

[0027] In one embodiment of the present utility model, as Figures 1-2 shown, a fixture with a chuck that is easy to disassemble is provided, including a base 100, a bracket 200, a chuck assembly 300, a chuck cantilever 400, and a handle 500. Pad feet 120 are provided at the four bottom corners of the lower surface of the base 100, so that the fixture has a certain height from the workbench, facilitating more space for processing the workpiece 700. A support wall 110 is fixedly provided at one end of the upper surface of the base 100, and a chute 120 is provided through the base 100 itself. A slider assembly 140 is slidably installed in the chute 120, and the slider assembly 140 clamps and fixes the workpiece 700 between it and the support wall 110. A bracket 200 is fixedly installed at one end of the upper surface of the base 100, and two brackets 200 are symmetrically and spaced apart. One end of the chuck cantilever 400 is rotatably installed inside one end of the two brackets 200, and the other end is fixedly installed with a chuck assembly 300. The chuck assembly 300 can be detachably separated from the chuck cantilever 400. The front end of the handle 500 is rotatably connected to the chuck cantilever 400 above the bracket 200, and a connecting portion 510 is further provided on the handle 500. The connecting portion 510 is rotatably connected to the inside of the two brackets 200 at the other end away from the chuck cantilever 400 through a connecting rod 600.

[0028] Specifically, the upper end of the bracket 200 is provided with a first mounting hole 220 and a second mounting hole 230, and a groove 210 is provided between the first mounting hole 220 and the second mounting hole 230. The first mounting hole 220 is rotatably connected to the chuck cantilever 400, and the second mounting hole 230 is rotatably connected. By rotatably mounting one end of the chuck cantilever 400 between the first mounting holes 220 of the two brackets 200, a connection hole is provided at the position where the chuck cantilever 400 is located above the bracket 200 for the front end of the handle 500 to be rotatably connected. A connection hole is also provided in the connection portion 510 on the handle 500 to rotatably connect one end of the connecting rod 600, and the other end of the connecting rod 600 is rotatably connected between the second mounting holes 230 of the two brackets 200. When the handle 500 pulls the chuck cantilever 400 to rotate and press down the workpiece 700, the connection portion 510 takes the inner wall of the groove 210 as a fulcrum to achieve a self-locking state.

[0029] Preferably, the chuck assembly 300 includes a chuck, a clamping member 320 and a first nut 330. The chuck includes a head 311 and a column body 312. The head 311 of the chuck is conical, and the bottom end of the head 311 of the chuck is a plane, which is convenient for abutting against the workpiece 700. The column body 312 at both ends of the chuck penetrates through the chuck cantilever 400. The clamping members 320 are symmetrically sleeved at both ends of the column body 312 and abut against the chuck cantilever 400. The two first nuts 330 respectively fix the clamping members 320 on the chuck cantilever 400 through thread fitting, and at the same time, the chuck assembly 300 is fixed on the chuck cantilever 400.

[0030] Preferably, a through groove 401 is provided at one end of the chuck cantilever 400 away from the bracket 200 for the column body 312 of the chuck to penetrate through the chuck cantilever 400, which is convenient for installing the chuck in the chuck cantilever 400 and also convenient for disassembly. That is, by unscrewing the first nut 330 of the chuck assembly 300, the entire chuck assembly 300 can be disassembled and decomposed, and the chuck assembly 300 is taken out of the through groove 401 of the chuck cantilever 400. On the contrary, by tightening the first nut 330, the clamping member 320 abuts tightly against the chuck, and the entire chuck assembly 300 is fixed on the chuck cantilever 400.

[0031] Preferably, the slider assembly 140 includes a bolt 141, a second nut 142 and a slider. The bolt 141 is perpendicular to the base 100 and penetrates through the chute 120. The slider is sleeved on the bolt 141 and abuts against the base 100. The second nut 142 fixes the slider through thread fitting with the bolt 141, and cooperates with the support wall 110 to clamp the workpiece 700. When the second nut 142 is loosened, the slider can move in the chute 120, which is convenient for placing workpieces 700 of different sizes here.

[0032] Preferably, two chutes 120 are provided in this embodiment, and correspondingly, two sets of slider assemblies 140 are provided, increasing the number of sliders, so that the workpiece 700 is clamped more stably in the horizontal direction.

[0033] Preferably, the upper surface of the handle 500 is provided with anti-slip stripes 520, so that the operator is not easily slipped off when grasping the handle 500.

[0034] Working principle: When the workpiece 700 is placed, the operator first manipulates the handle 500 to pull backward horizontally. Under the traction of the chuck cantilever 400, the chuck is lifted upward. Then, the slider is adjusted to a suitable position according to the size of the workpiece 700. After tightening the second nut 142, the slider is fixed, so that the support wall 110 and the slider jointly fix the workpiece 700 in the horizontal direction. Then, while manipulating the handle 500 to press backward and downward and rotate at the same time, the connecting arm 400 is driven to pull the chuck to press the workpiece 700 downward, pressing the workpiece 700 tightly in the vertical direction to avoid deviation and jitter. And when the requirements of the workpiece 700 or the chuck needs to be replaced, the first nut 330 of the chuck assembly 300 is directly loosened, the chuck assembly 300 is disassembled and taken out from the through groove 401 of the chuck cantilever 400, and the required chuck is switched, and the disassembly is convenient.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
