Description

Technical Field

[0001] This invention relates to the field of workpiece processing equipment technology, and in particular to a precision positioning mechanism for CNC rotary cutting equipment. Background Technology

[0002] The forming process of workpieces generally involves multiple processes such as cutting and grinding. For ordinary workpieces, they need to be clamped and fixed in advance to prevent them from moving during the cutting process and affecting the cutting effect. However, after clamping and fixing, it is impossible to accurately position the cutting position, resulting in low cutting quality.

[0003] Therefore, the positioning mechanism of the cutting equipment proposed in the prior art, by setting two symmetrical translation mechanisms in the middle of the frame, is used to adjust the position of the workpiece to be cut, improve the positioning accuracy, reduce the deviation of the workpiece to be cut, reduce the parallelism deviation of the workpiece cutting surface, and improve the cutting quality of the workpiece. The fixed clamping part and the movable clamping part are used to fix the workpiece. At the same time, by setting a clamping device in the fixed clamping part, the workpiece can be better fixed, preventing the workpiece from shifting during the cutting process, improving the cutting accuracy and the cutting quality.

[0004] However, in actual use, this device adjusts the cutting position of the workpiece through two translation mechanisms and detects whether the workpiece has shifted through an infrared measuring instrument. However, after measuring the workpiece, it is not possible to quickly determine the exact location of the cutting blade on the workpiece, which often leads to deviations in the cutting position when cutting the workpiece, resulting in unsatisfactory cutting accuracy. Summary of the Invention

Support platforms are fixed to the left and right sides of the rear end of the upper surface of the base. A support rod is horizontally fixed between the two support platforms. The main frame is nested outside the support rod. A rotary cutting blade is rotatably connected to the front end of the main frame. An outer frame is fixed to the front end of the main frame.

Fixing frames are fixed to the left and right ends of the upper surface of the worktable. A positioning component is fixed to the front end of the upper surface of the worktable.

[0007] As a further embodiment of the present invention: the positioning component consists of a fixed plate, a slider, a front indicator, an inner cylinder, a push switch, and a sliding plate;

[0008] Specifically, a fixing plate is fixed to the front end of the upper surface of the fixing frame, a slider is embedded inside the front end of the fixing plate, a front indicator is fixed to the top of the slider, an inner cylinder is embedded inside the rear end of the slider, a push switch is fixed to the front end of the inner cylinder, and a slider is embedded inside the rear end of the push switch.

[0009] As a further aspect of the present invention: the limiting hole at the front end of the slider is nested on the outside of the limiting rod at the front end of the fixed plate, the slider slides horizontally left and right on the outside of the limiting rod, and a screw with its bottom end tightly attached to the upper surface of the limiting rod is embedded in the front end of the slider.

[0010] As a further embodiment of the present invention: a scale strip is fixed in the middle of the upper surface of the fixing plate, the front indicator is set at the front end of the scale strip, and a rear indicator plate is fixed on the front surface of the bottom post, the rear indicator plate is set at the rear end of the scale strip.

[0011] As a further aspect of the present invention: the slide plate slides horizontally back and forth inside the inner cylinder, the front end of the slide plate abuts against the button on the back of the push switch, and a return spring is connected to the outer side of the front end of the slide plate.

[0012] As a further aspect of the present invention: an inner plate is fixed to the front end of the bottom column, and the middle part of the sliding piece and the middle part of the inner plate are both on the same longitudinal horizontal plane. Both the inner plate and the sliding piece are made of a material with a magnetic negative pole.

[0013] As a further aspect of the present invention: the fixed plate is provided with a sliding groove inside, and the bottom column under the outer frame is embedded in the sliding groove, and the bottom column slides horizontally left and right inside the sliding groove.

[0014] As a further aspect of the present invention: the limiting post above the bottom post is precisely embedded in the sliding groove below the connecting post, the limiting post is rectangular and closely attached to the inner wall of the sliding groove, and the connecting post moves up and down on the outside of the limiting post.

[0015] As a further embodiment of the present invention: an LED high-intensity light and a beam splitter are fixed in the middle of the back side of the base column, the beam splitter is nested on the outside of the LED high-intensity light, and 8-20 small holes are equidistantly arranged from top to bottom in the middle of the back side of the beam splitter.

[0017] This invention provides a precision positioning mechanism for CNC rotary cutting equipment, which has the following advantages:

[0018] 1. When the main frame of the present invention moves left and right to adjust the cutting position of the workpiece, the main frame will drive the bottom column to slide left and right in the fixed plate through the outer frame, connecting column and limiting column. When the bottom column reaches the cutting position indicated by the front indicator on the slider, the inner plate at the front end of the bottom column is exactly located on the back of the sliding plate in the inner cylinder. The inner plate and the sliding plate generate a repulsive force between them, pushing the sliding plate to move in the inner cylinder and press the push switch, so that the push switch closes the drive mechanism of the main frame in time, thereby realizing precise positioning and cutting of the workpiece.

[0019] 2. When the workpiece cut by this invention is fixed between two fixed frames on the worktable, the precise cutting position of the workpiece can be adjusted by pushing the slider to move left and right at the left and right ends of the fixed plate. Before cutting, the LED high-intensity light will emit light through the beam splitter plate to illuminate the outside of the workpiece, indicating the cutting position of the workpiece more intuitively. At the same time, the length of the workpiece and the cutting position can be determined by observing the value of the scale bar on the fixed plate indicated by the rear indicator plate. It has high flexibility and is more convenient to use. Attached Figure Description

Detailed Implementation

[0029] Example 1, please refer to Figure 1-7 A precision positioning mechanism for a CNC rotary cutting machine includes a base 1, a support platform 2, a support rod 201, a main frame 202, a rotary cutting blade 203, and a worktable 4. Support platforms 2 are fixed to the left and right sides of the rear end of the upper surface of the base 1. A support rod 201 is horizontally fixed between the two support platforms 2. The main frame 202 is nested outside the support rod 201. The rotary cutting blade 203 is rotatably connected to the front end of the main frame 202. An outer frame 3 is fixed to the front end of the main frame 202. The worktable 4 is fixed to the front end of the upper surface of the base 1. A connecting column 301 is vertically fixed below the front end of the outer frame 3. A limiting column 302 is nested below the outer side of the connecting column 301. A bottom column 303 is fixed to the bottom end of the limiting column 302. Fixing frames 401 are fixed to the left and right ends of the upper surface of the worktable 4. A positioning component is fixed to the front end of the upper surface of the worktable 4.

[0030] The positioning assembly consists of a fixed plate 402, a slider 403, a front indicator 404, an inner cylinder 5, a push switch 501, and a sliding plate 502.

[0031] A fixing plate 402 is fixed to the front end of the upper surface of the fixing bracket 401. A slider 403 is embedded inside the front end of the fixing plate 402. A front indicator 404 is fixed to the top of the slider 403. An inner cylinder 5 is embedded inside the rear end of the slider 403. A push switch 501 is fixed to the front end of the inner cylinder 5. A slider 502 is embedded inside the rear end of the push switch 501.

[0032] The limiting hole at the front end of the slider 403 is nested on the outside of the limiting rod at the front end of the fixed plate 402. The slider 403 slides horizontally left and right on the outside of the limiting rod. A screw with its bottom end tightly attached to the upper surface of the limiting rod is embedded in the front end of the slider 403.

[0033] By pushing the slider 403 to move left and right at the front end of the fixed plate 402, the precise cutting position indicated by the slider 403 can be adjusted. By turning the screw on the slider 403 to fit tightly against the outside of the limiting rod of the fixed plate 402, the slider 403 can be limited and fixed.

[0034] A scale strip is fixed in the middle of the upper surface of the fixing plate 402, and the front indicator 404 is set at the front end of the scale strip. A rear indicator plate 305 is fixed on the front surface of the bottom column 303, and the rear indicator plate 305 is set at the rear end of the scale strip.

[0035] As the main frame 202 moves left and right outside the support rod 201, the specific position of the rotary cutter 203 between the two fixed plates 402 can be determined by reading the value of the scale bar on the fixed plate 402 indicated by the rear indicator plate 305.

[0036] As the slider 403 moves left and right at the front end of the fixed plate 402, the cutting position for positioning the workpiece can be determined by reading the value of the scale bar on the fixed plate 402 indicated by the indicator 404.

[0037] Example 2, please refer to Figure 1-7 The difference between Embodiment 2 and Embodiment 1 is that the slider 502 slides horizontally back and forth inside the inner cylinder 5, the front end of the slider 502 abuts against the button on the back of the push switch 501, and a return spring is connected to the outer side of the front end of the slider 502.

[0038] The front end of the bottom post 303 is fixed with an inner plate 304. The middle part of the slider 502 and the middle part of the inner plate 304 are on the same longitudinal horizontal plane. Both the inner plate 304 and the slider 502 are made of materials with magnetic negative poles.

[0039] Among them, the push switch 501 is wirelessly connected to the drive structure that drives the main frame 202 to move left and right.

[0040] When the bottom column 303 reaches the cutting position indicated by the front indicator 404 on the slider 403, the inner plate 304 at the front end of the bottom column 303 is exactly located on the back of the slider 502 in the inner cylinder 5. The inner plate 304 and the slider 502 generate a repulsive force to push each other, and the slider 502 moves in the inner cylinder 5 to compress the press switch 501 and the return spring, so that the press switch 501 closes the drive mechanism of the main frame 202 in time, thereby achieving precise positioning and cutting of the workpiece.

[0041] When the slider 502 and the inner plate 304 are not on the same longitudinal horizontal plane, the return spring returns to its original position and pushes the slider 502 to stop pressing the button of the switch 501. The drive structure can drive the main frame 202 to move left and right normally.

[0042] The fixed plate 402 has a sliding groove inside, and the bottom column 303 under the outer frame 3 is embedded in the sliding groove. The bottom column 303 slides horizontally left and right inside the sliding groove.

[0043] As the main frame 202 moves left and right on the outside of the support rod 201, the bottom column 303 moves left and right in the groove of the fixed plate 402, and the rear indicator plate 305 on the bottom column 303 moves left and right on the scale bar on the fixed plate 402 in real time. By reading the value indicated by the rear indicator plate 305, the specific position of the rotary cutter 203 between the two fixed plates 402 can be known.

[0044] The limiting post 302 above the bottom post 303 is precisely embedded in the sliding groove inside the connecting post 301. The limiting post 302 is rectangular and closely attached to the inner wall of the sliding groove. The connecting post 301 moves up and down on the outside of the limiting post 302.

[0045] When the main frame 202 is driven by the drive structure to move the main frame 202 downward to cut the workpiece, the outer frame 3 will move downward along with the main frame 202. The connecting column 301 of the outer frame 3 will descend normally outside the limiting column 302. After the main frame 202 rises, the connecting column 301 will rise outside the limiting column 302. Subsequently, the bottom column 303 can also be moved left and right normally through the limiting column 302.

[0046] Example 3, please refer to Figure 1-7 The difference between Embodiment 3 and Embodiment 2 is that an LED high-intensity lamp 306 and a beam splitter 307 are fixed in the middle of the back of the bottom column 303. The beam splitter 307 is nested on the outside of the LED high-intensity lamp 306. 8-20 small holes are equidistantly arranged from top to bottom in the middle of the back of the beam splitter 307.

[0047] As the main frame 202 moves left and right outside the support rod 201, the LED high-intensity light 306 will emit light through the small holes of the beam splitter 307 covering its outer side. This light will illuminate the outer side of the workpiece, more intuitively indicating the cutting position where the rotary cutter 203 will cut the workpiece.

[0048] The middle parts of the connecting post 301, the limiting post 302, the bottom post 303, the rear indicator plate 305, and the splitting plate 307 are all on the same longitudinal horizontal plane as the middle part of the rotary cutter 203.

[0049] As the main frame 202 moves left and right outside the support rod 201, the specific position of the rotary cutter 203 between the two fixed plates 402 can be determined by reading the value of the scale bar on the fixed plate 402 indicated by the rear indicator plate 305.

[0050] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
