Description

Technical Field

[0002] Cutting edge opening, also known as sharpening, is the process of grinding away the material that affects the sharpness of the cutting edge, exposing the steel part and making the tool sharper. A cutting edge opening device is a device used to perform this operation. Precision tools are tools used for high-precision machining and are widely used in the industrial manufacturing field. After machining, precision tools need to be sharpened to ensure that the tool can achieve the ideal cutting effect and machining accuracy in subsequent use.

[0003] According to Chinese patent application number 202322174757.X, a precision cutting tool edge opening device is disclosed, relating to the field of cutting tool edge opening.

The V-shaped groove 120 is equipped with a diversion pipe 213 and a spray pipe 214 at both ends. The spray pipe 214 is connected to one end of the diversion pipe 213. The collection assembly 220 includes a guide groove 221 and a through groove 223 for guiding the coolant flow, and a collection groove 222 and a drain pipe 224 for collecting the coolant. The guide groove 221 is opened on the top of the operating table 110, the through groove 223 is opened in the inner cavity of the guide groove 221, the collection groove 222 is fixed in the inner cavity of the operating table 110 and is connected to the inner cavity of the through groove 223, one end of the drain pipe 224 is connected to the collection groove 222, and the other end of the drain pipe 224 extends to the outside of the operating table 110.

[0027] like Figures 1-4 As shown, the spray assembly 210 in the lubrication mechanism 200 can lubricate and cool the tool during the opening process.

[0028] Example 2

[0029] Reference Figures 1-2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] In this embodiment, the inner cavity of the protective cover 130 is also equipped with a transverse component 300 and a clamping component 400.

The sprayed coolant falls onto the operating table, is collected through the guide channel 221, flows into the collection tank 222 through the through channel 223, and is then discharged through the drain pipe 224, realizing the recycling of coolant.

[0033] Example 3

[0034] Reference Figures 2-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0035] In this embodiment, the transverse component 300 includes a support frame 310 for installation, a servo motor 320 for transverse movement, a reducer 330, a lead screw 340 and a nut 350, a support plate 360 ​​and a connecting plate 370 for support, and a limiting groove 380 for limiting the support plate 360.

[0036] The clamping assembly 400 includes a cylinder 420 for pushing, a fixing plate 410 for supporting the cylinder 420, a pneumatic gripper 440 for clamping the tool, a mounting plate 430 for supporting the pneumatic gripper 440, and a slide block 450 and a slide rail 460 for limiting the mounting plate 430.

[0037] The support frame 310 is fixedly connected to the inner wall of the protective cover 130. The servo motor 320 and the reducer 330 are both fixed to one end of the support frame 310. The lead screw 340, nut 350 and support plate 360 ​​are all located in the inner cavity of the support frame 310. The connecting plate 370 is located on the surface of the support frame 310. The top and bottom of the support frame 310 are provided with limit grooves 380. Both ends of the support plate 360 ​​pass through the limit grooves 380 and extend to the outside of the support frame 310, and are fixedly connected to the connecting plate 370.

[0038] One end of the lead screw 340 is movably connected to the inner wall of the support frame 310 via a bearing. The nut 350 is sleeved on the surface of the lead screw 340 and threadedly connected to the lead screw 340. One end of the nut 350 is fixedly connected to the support plate 360. The output shaft of the servo motor 320 is drivenly connected to the input shaft of the reducer 330. The output shaft of the reducer 330 passes through the inner cavity of the support frame 310 and is drivenly connected to the lead screw 340.

[0039] The fixing plate 410 is fixed to the surface of the connecting plate 370, the cylinder 420 is fixed to the top of the fixing plate 410, and the slide rails 460 are fixedly connected to both sides of the surface of the fixing plate 410. The slide block 450 is located on the surface of the slide rail 460 and is slidably connected to the slide rail 460. The mounting plate 430 is fixed to the surface of the slide block 450, the pneumatic gripper 440 is fixed to the surface of the mounting plate 430, and the output end of the cylinder 420 is fixedly connected to the mounting plate 430.

[0040] like Figures 2-4 As shown, the servo motor 320, reducer 330, lead screw 340, and nut 350 in the transverse assembly 300 work together to achieve precise transverse movement of the tool. The limiting groove 380 limits the support plate 360, ensuring the stability and accuracy of the transverse movement process. It can be precisely adjusted according to the opening requirements of different tools, improving the accuracy and efficiency of the opening operation. The clamping assembly 400 pushes the mounting plate 430 through the cylinder 420, so that the pneumatic gripper 440 can stably clamp the tool. The slide 450 and slide rail 460 limit the mounting plate 430 to ensure the smoothness of the clamping process. Stable clamping can ensure the positional accuracy of the tool during the opening process and avoid tool shaking affecting the opening quality.

[0041] In use, first turn on the device and inject coolant into the storage tank 211. The internal components of the device can be inspected and maintained through the inspection door 140 on the control panel 110. The cylinder 420 operates, its output end pushing the mounting plate 430. The mounting plate 430 slides smoothly on the slide rail 460 via the slide block 450. The pneumatic gripper 440 is fixed to the mounting plate 430 and moves with it. Simultaneously, the pneumatic gripper 440 clamps the tool, placing it in a suitable opening position. The servo motor 320 starts, and power is transmitted to the wire via the reducer 330. The rotation of rod 340 and lead screw 340 causes nut 350 to move linearly along lead screw 340. Support plate 360, which is fixed to nut 350, moves accordingly. Both ends of support plate 360 ​​pass through limit groove 380 and are connected to connecting plate 370, ensuring the stability and accuracy of movement. This drives connecting plate 370 to move laterally, adjusting the position of the cutter in the horizontal direction. The cutter is moved above V groove 120 and lowered, so that the cutting edge of the cutter contacts the whetstone in V groove 120. The transverse moving component 300 drives the cutter to move laterally, realizing the opening and closing operation of the cutting edge.

[0042] The delivery pump 212 starts, drawing coolant from the storage tank 211 through the connecting pipe 215, and then delivering it through the delivery pipe 216 to the distribution pipe 213. The distribution pipe 213 distributes the coolant to the spray pipes 214 at both ends, and finally sprays it onto the contact area between the cutting tool and the whetstone through the nozzles, which plays a role in lubrication and cooling, reducing tool wear and heat generation. The sprayed coolant falls onto the operating table, is collected through the guide channel 221, flows into the collection tank 222 through the through channel 223, and is then discharged through the drain pipe 224, realizing the recycling of coolant.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
