Arbitrary angle positioning device of cutting machine

Abstract

The locator for arbitrary angle of cutter comprises a base with rotation shaft of a rotatable plant for arbitrary angle, which is characterized in that, arranging location unit on plant bottom, a servo unit with active sleeve on rotation shaft, and fixation unit screwed on shaft for locking and releasing; wherein, there is a location part to provide the location unit block and join on the servo unit; when the plant rotates to this place next time, it will generate location effect of automatic block.

Description

【Technical field】 [0001] The present invention relates to a cutting machine, in particular to an arbitrary angle positioning device of the cutting machine which can have an automatic locking positioning effect when the workbench is rotated to any angular position. 【Background technique】 [0002] see figure 1 As shown, the general cutting machine 10 mainly includes a base 11, a workbench 12 on the base 11 that can swing left and right, and a workbench 12 horizontally arranged behind the workbench 12 for a workpiece (not shown) to lean against. The baffle plate 13, and a sawing unit 14 that can swing up and down and is pivotally arranged at the rear end of the base 11, the sawing unit 14 has a body 141, a circular saw blade 142 with a shaft arranged inside the body 141, a fixed The handle 143 connected to the side of the main body 141, and a cover 144 that covers the circular saw blade 142 and can be flipped, press the handle 143 to open the eye protection cover 144 to expose...

Problems solved by technology

[0005] The cutting machine 10 mentioned above can indeed allow the workbench 12 to achieve two positioning functions at any angle and a special angle, but there is still room for improvement in use. The workbench 12 is fixed at any angle by using the locking button 121 for locking. When the operator wants to perform repeated and multiple cutting work at this angular position, first turn the worktable 12 to this angular position for the first cutting. Since this angular position does not have a fast positioning mechanism, the operator can only Remember the angle value of this position, and wait until the next time when the cutting work will be performed at the same position, the operator will rotate the worktable 12 to the same angular position as last time according to the memorized angle value, but the rotation amount of the worktable 12 It is not easy to control it to be exactly the same, and the angle position of each rotation will be slightly deviated. If you want to achieve the degree of accuracy, you need to make fine adjustments to the workbench 12 repeatedly with slight hand touches, which is quite time-consuming and expensive. It is laborious, and may not be able to achieve the best accuracy, and it is not convenient to use
