Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, and in particular to a cutting device for producing metal drill bits. Background Art

[0002] Metal drills are tools used to drill holes in metal workpieces. They are usually made of high-speed steel or carbide and have specific geometric shapes and sharp cutting edges. They are widely used in industrial manufacturing and processing fields and can effectively cut various metal materials such as steel, aluminum, copper, stainless steel, etc. to meet various processing requirements, such as machinery manufacturing, automobile manufacturing, and aerospace industries.

[0003] During the process of cutting raw materials, the metal drill needs to measure the curvature of the raw materials. The curvature of the raw materials will directly affect the geometric shape and size of the processed product. If the raw materials are curved, the processing may cause the product to have an irregular or asymmetrical shape, thereby affecting the accuracy and quality of the product. During the processing of the existing device, some curved raw materials of the drill raw materials cannot be manually identified during the production process, so the raw materials are inspected before processing. After the drill part is inspected, the next process is moved to cut the workpiece. Because the curvature of the raw materials cannot be manually identified, each raw material needs to be measured before processing. This is time-consuming in the entire processing process and is not conducive to mass production of drills. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention will be further described below in conjunction with the embodiments.

[0033] Example: Refer to Figures 1 to 10 , a cutting device for producing metal drill bits, comprising:

[0034] A base plate 1, on the upper end surface of which a rotary chuck 6 is fixedly mounted, the rotary chuck 6 is used for clamping and driving the workpiece;

[0035] The measuring assembly 2 is driven to move in the length direction of the bottom plate 1 and measure the curvature of the workpiece. The measuring assembly 2 includes a moving plate 201. A through hole is provided at the center of the moving plate 201. A liquid storage cavity 202 is provided on the inner wall of the moving plate 201. The liquid storage cavity 202 is filled with hydraulic oil. A plurality of push rods 203 are elastically slidably arranged in a circular array between the liquid storage cavity 202 and the through hole. A first roller 204 is rotatably mounted on one end of the push rod 203 near the axis of the through hole. A trigger cross bar 208 is provided at the upper end of the moving plate 201 for lifting and lowering according to the hydraulic pressure of the hydraulic oil.

[0036] The lifting component 3 is driven to rise and fall according to the diameter of the workpiece. The lifting component 3 includes a lifting rod 308. A variable resistance button 309 is embedded in the central position of the lifting rod 308. The variable resistance button 309 is arranged above the trigger cross bar 208, and the variable resistance button 309 can contact the trigger cross bar 208.

[0037] During the measurement of the workpiece, the measuring component 2 can contact the workpiece through a plurality of first rollers 204 during movement. When the curvature of the workpiece reaches a certain degree, the hydraulic pressure of the internal hydraulic oil is used to trigger the switch to stop the detection.

[0038] Reference Figures 1 to 3 A first spring 205 is fixedly installed at one end of the push rod 203 away from the axis of the insertion hole, and the other end of the first spring 205 is fixed to the inner wall of the liquid storage chamber 202. Two fixed sleeves 206 are symmetrically installed on the upper end surface of the movable plate 201. The fixed sleeve 206 is connected to the liquid storage chamber 202. A linkage rod 207 is arranged on the inner wall of the fixed sleeve 206. The linkage rod 207 is composed of a piston slide and a short rod fixed up and down. The piston slide is airtightly slidably connected to the inner wall of the fixed sleeve 206. The upper end of the short rod passes through the fixed sleeve 206 and is fixed to the trigger cross bar 208.

[0039] By setting the first spring 205, the first roller 204 and the push rod 203 can maintain connection with the inner wall of the liquid storage chamber 202 when the hydraulic oil is compressed and squeezed. When the first roller 204 and the push rod 203 are not compressed, the elastic force of the first spring 205 can make the first roller 204 and the push rod 203 rebound to their original positions.

[0040] Reference Figures 4 to 5A U-shaped plate 301 is fixedly installed at an upper position on one side of the movable plate 201 close to the rotary chuck 6, and a hydraulic barrel 302 is embedded at the lower end of the U-shaped plate 301. A piston plate 306 is airtightly and slidably installed on the inner wall of the hydraulic barrel 302. A connecting rod 303 is fixedly installed on the lower end surface of the piston plate 306. The lower end of the connecting rod 303 penetrates the piston plate 306 and is rotatably installed with a second roller 304. The axis line of the second roller 304 is vertically staggered with the axis line of the insertion hole in three dimensions. A third spring 305 is fixedly installed between the upper end surface of the piston plate 306 and the inner wall of the hydraulic barrel 302. Two hydraulic boxes 307 are symmetrically installed on the upper end surface of the movable plate 201. The hydraulic box 307 is connected to the hydraulic barrel 302 through a pipeline. The lifting rod 308 consists of a long rod and two short rods. The two short rods are airtightly and slidably connected to the inner wall of the hydraulic box 307.

[0041] By three-dimensionally interlacing the axis of the second roller 304 and the axis of the through hole, the second roller 304 can contact the outer surface of the workpiece when the movable plate 201 moves, and the distance that the second roller 304 drives the connecting rod 303 to rise is the distance from the axis of the workpiece to the outer surface.

[0042] Reference Figures 3 to 8 A baffle plate 7 is fixedly mounted on the upper end surface of the bottom plate 1 and at a position away from the rotary chuck 6. The cutting device also includes a cutting assembly 4, which includes a cutting machine 414. The cutting machine 414 is driven to move up and down by the movement of the moving plate 201;

[0043] The cutting assembly 4 also includes a straight rod 403 fixed to the upper end surface of the piston plate 306, the upper end of the straight rod 403 passes through the hydraulic barrel 302 and extends to the top of the hydraulic barrel 302, the upper end surface of the U-shaped plate 301 is fixedly installed with an external box 401, the lower end surface of the external box 401 is connected and installed with an air bag 402, the inside of the air bag 402 is filled with gas, and the air bag 402 can contact the straight rod 403, and the bottom end of the external box 401 is fixedly installed with a closed valve 404, the middle of the closed valve 404 is provided with an air inlet 405, and the inner wall of the closed valve 404 is slidably installed with a valve 406, and the side of the valve 406 close to the movable plate 201 passes through the external box 401, and the valve 406 is connected to the external box 401. At least one fourth spring 415 is fixedly installed on the opposite side of the connecting box 401, and an air vent 407 is opened in the middle of the valve 406. When the fourth spring 415 is in a normal state, the air vent 407 is misaligned with the air inlet 405. A lifting plate 408 is airtightly slidably installed on the inner wall of the external connecting box 401, and a connecting switch 409 is fixedly installed on the inner top end of the external connecting box 401. A self-resetting slider is slidably installed on the lower end surface of the connecting switch 409, and the self-resetting slider is fixed to the lifting plate 408. An external frame 416 is fixedly installed on the side of the rotary chuck 6 close to the movable plate 201 and in an upper position, and a top block 417 is fixedly installed on the side of the external frame 416 close to the movable plate 201.

[0044] By setting the baffle 7, when the workpiece is fixed, one end of the workpiece can contact the baffle 7, and the distance between the baffle 7 and the rotary chuck 6 is fixed. Therefore, when cutting, it is only necessary to adjust the moving distance of the cutting component 4 according to the required length of the workpiece to cut the required length of the workpiece.

[0045] Reference Figure 8 A fixed box 410 is fixedly installed at an upper position on a side of the movable plate 201 away from the rotary chuck 6, and a lifting connecting plate 413 driven to lift is slidably installed inside the fixed box 410. The lifting connecting plate 413 consists of a sliding part and a mounting part, and the mounting part is fixed to the cutting machine 414 at a lower position on a side away from the movable plate 201.

[0046] By disposing the fixing box 410 , the cutting machine 414 can be raised and lowered inside the fixing box 410 through the sliding part, so as to cut the workpiece.

[0047] Reference Figure 8 A driving source 411 is fixedly installed on the upper end surface of the fixed box 410, and the output end of the driving source 411 passes through the fixed box 410 and is fixedly connected to a threaded rod 412. The threaded rod 412 is rotatably connected to the upper and lower inner walls of the fixed box 410, and the threaded rod 412 is threadedly connected to the sliding part.

[0048] By turning on the driving source 411, the sliding part and the mounting part can be driven to drive the cutting machine 414 to move up and down, so as to cut the workpiece.

[0049] Reference Figures 9 and 10 , also includes a correction component 5, which is driven to move in a two-dimensional plane on the upper end surface of the base plate 1 and is used to correct the workpiece. The correction component 5 includes two driving support rods 501, and the lower end surfaces of the two driving support rods 501 are jointly fixedly installed with two docking boxes 502. The two docking boxes 502 have V-shaped grooves on opposite sides. The V-shaped groove is composed of two horizontally symmetrical inclined grooves. A plurality of correction rollers 503 are rotatably installed inside the inclined groove. The rotary chuck 6 is set as the starting point and the baffle 7 is set as the end point. A line a is formed along the length of the base plate 1, and the protrusion degree of the plurality of correction rollers 503 relative to the inclined groove along the direction of the line a decreases successively.

[0050] By setting the correction component 5, when a workpiece with a certain curvature is detected, the workpiece can be straightened by the correction component 5 to reduce the consumption of raw materials.

[0051] The working principle of the present invention is as follows:

[0052] By passing the workpiece through the rotary chuck 6, one end of the workpiece is brought into contact with and tightened against the baffle 7, and the workpiece is fixed by starting the rotary chuck 6, and the part of the workpiece passing through the rotary chuck 6 will be fixed between the rotary chuck 6 and the baffle 7. It should be noted that the rotary chuck 6 includes an annular plate with claws inside, which can clamp the workpiece in a self-centering manner and drive the workpiece to rotate. It can be equipped with an automated control system that can automatically adjust the telescopic length of the claws according to the diameter and length of the workpiece to ensure that the clamping force is appropriate and the workpiece can rotate freely.

[0053] When the workpiece passes through the rotary chuck 6 and contacts and is pressed against the baffle 7, part of the outer surface of the workpiece will pass through the interlaced hole and roll in contact with the second roller 304 during the process. When the second roller 304 contacts the outer surface of the workpiece, it will drive the connecting rod 303 and the piston plate 306 to rise (the rise of the piston plate 306 will drive the straight rod 403 to rise, and the straight rod 403 rises and contacts the internal gas of the airbag 402). When the piston plate 306 rises, it will be in airtight sliding connection with the inner wall of the hydraulic barrel 302 and compress the third spring 305. During this process, the piston plate 306 will continuously compress the hydraulic barrel 30 2, so that the hydraulic oil enters the hydraulic box 307 through the pipeline. The hydraulic oil entering the hydraulic box 307 drives the lifting rod 308 to rise through the hydraulic pressure, so that the lifting rod 308 drives the variable resistance button 309 to rise. It should be noted that in the process of the second roller 304 rolling contact with the workpiece, because the second roller 304 and the through hole and the axis of the rotary chuck 6 coincide, and the axis of the workpiece after being clamped by the rotary chuck 6 coincides with the axis of the rotary chuck 6, so in the process of the second roller 304 contacting the outer surface of the workpiece and rising, the rising distance is the distance from the axis of the workpiece to the outer surface.

[0054] When the workpiece passes through the through hole, the multiple distributed push rods 203 drive the first roller 204 to contact the outer surface of the workpiece to be processed, and the workpiece is driven to rotate by starting the rotary chuck 6, and the outer surface of the workpiece is in sliding contact with the first roller 204. The driving mechanism drives the moving plate 201 to move from the position of the baffle 7 to the position of the rotary chuck 6 (the baffle 7 is set on the upper end surface of the driving mechanism), and the first roller 204 continuously rolls and contacts with the outer surface of the workpiece. If the curvature of a certain part of the workpiece is too large, the outer diameter of the workpiece will expand with the rotation, and the expanded outer diameter will increase. The circumferential diameter will drive the first roller 204 and the push rod 203 to slide inside the movable plate 201 to compress the first spring 205 and squeeze the hydraulic oil set in the liquid storage chamber 202. The squeezed hydraulic oil will be transported to the inside of the fixed sleeve 206. The hydraulic pressure of the hydraulic oil in the fixed sleeve 206 will drive the piston slide plate and the short rod to rise, trigger the cross bar 208 to rise, and contact with the variable resistance button 309 to be triggered. The variable resistance button 309 is connected to the input end of the controller (not shown in the drawings) through a signal line. The controller is connected to the drive mechanism and the rotary chuck 6 respectively through the signal line to control 6 to stop running;

[0055] It should be noted that the curvature of the workpiece will drive the trigger cross bar 208 to rise to different distances, and the pressures for contacting and triggering the variable resistance button 309 at different rising distances are different (the working principle of the variable resistance button is to adjust the parameters by changing the resistance when the button is pressed. Specifically, the resistance of the button changes with the pressing force). The variable resistance button 309 can detect different trigger pressures to measure the different curvatures of the workpiece. When the curvature of the workpiece is too large, the pressure to drive the trigger cross bar 208 to contact the variable resistance button 309 will increase. When the curvature of the workpiece is small, the pressure to drive the trigger cross bar 208 to contact the variable resistance button 309 will be small. The controller determines the curvature of the workpiece by the contact pressure. When the curvature is too large, the drive mechanism and the rotary chuck 6 will be connected through a signal line to stop running and remove the workpiece for abandonment. When the curvature is small, the controller will connect the drive mechanism through a signal line to drive the correction component 5.

[0056] In the process of driving the correction component 5, the driving mechanism will drive the correction component 5 to move from the position of the rotary chuck 6 to the position of the baffle 7. Before this, the driving mechanism will drive the correction component 5 to clamp the workpiece, so that the multiple correction rollers 503 are respectively in contact with the workpiece, and the correction rollers 503 with different protrusion degrees are arranged inside the inclined groove (such as Fig.10) will come into contact with the workpiece and apply different clamping forces to the workpiece during the movement to straighten the workpiece with a smaller curvature. When moving toward the position of the baffle 7, the correction roller 503 with the smallest protrusion first contacts the part of the workpiece with a larger curvature, and then the correction roller 503 in the middle position contacts, and finally the correction roller 503 with a larger protrusion contacts, to gradually straighten the bent workpiece. When moving toward the position of the rotary chuck 6, the bent workpiece has been gradually straightened, and the correction roller 503 can further straighten the workpiece to enhance the straightening effect.

[0057] It should be noted that when the driving mechanism drives the correction component 5 to move to the position of the baffle 7, the driving mechanism will drive the support rod 501 to move in the opposite direction away from the outer surface of the workpiece, and the driving mechanism will drive the movable plate 201 to move to the position of the rotary chuck 6, and then drive the support rod 501 to contact the outer surface of the workpiece by centering and clamping, and drive the docking box 502 to move from the position of the baffle 7 to the position of the rotary chuck 6 to straighten the workpiece again to ensure that the workpiece can be fully straightened. When the docking box 502 is straightened back to the position of the rotary chuck 6, the two driving support rods 501 are driven to move in the opposite direction, and the movable plate 201 will be driven to move from the position of the rotary chuck 6 back to the position of the baffle 7.

[0058] When the movable plate 201 returns to the position of the baffle plate 7, the rotary chuck 6 will drive the workpiece to rotate again. During the rotation, the workpiece will contact the first roller 204 again, and the curvature of the workpiece will be tested again to detect the straightening effect. After it is determined that the curvature of the workpiece meets the standard, the driving structure will drive the movable plate 201 to move in the direction close to the baffle plate 7, driving the valve 406 to contact the top block 417 supported by the external frame 416, driving the valve 406 to slide and compress inside the closed valve 404. The fourth spring 415 makes the vent 407 coincide with the air inlet 405, so that the gas inside the squeezed airbag 402 is transported from the vent 407 and the air inlet 405 to the inside of the external box 401, so that the air pressure inside the external box 401 increases, driving the lifting plate 408 to rise and contact the self-resetting slide to trigger the connection switch 409, which is connected to the driving source 411 through the signal line. The driving source 411 drives the threaded rod 412 to rotate, driving the lifting connecting plate 413 and the cutting machine 414 to descend to cut the workpiece;

[0059] It should be noted that the airbag 402 has a certain elastic strength. When it is not squeezed by external pressure, the airbag 402 will return to its original state and absorb the gas from the inside of the external box 401 back into it. After the gas inside the external box 401 is sucked back, the internal air pressure will decrease, and the lifting plate 408 will drop back to its original position and stop contacting the self-resetting spring piece, so that the connection switch 409 stops connecting to the signal of the drive source 411.

[0060] During the process of inspecting and straightening the outer surface of the workpiece, the driving structure is used to drive the movable plate 201 to move from the position of the baffle 7 to the position of the rotary chuck 6, so that the first roller 204 contacts the outer surface of the workpiece. If the workpiece has a certain curvature, the outer diameter of the workpiece driven to rotate will increase with the rotation and continuously contact the first roller 204, so that the push rod 203 slides inside the movable plate 201, squeezing the hydraulic oil set in the liquid storage chamber 202, and driving the linkage rod 207 and the trigger cross bar 208 to rise through the hydraulic pressure, and contact with the variable resistance button 309, and the controller is used to judge the size of the curvature to determine whether the workpiece can be straightened or abandoned. Through the setting of the correction component 5, the workpiece with a smaller curvature can be straightened. During the straightening process, the support rod 501 is driven to drive the docking box 502 to align and clamp the workpiece and contact it, and move from the position of the rotary chuck 6 to the baffle 7. The workpiece is straightened by applying different clamping forces at different protrusions of the correction roller 503. When the correction roller 503 moves to the position of the baffle 7 and encounters an obstacle from the movable plate 201, the docking box 502 is driven to move in the opposite direction by driving the movable plate 201 to move to the position of the rotary chuck 6, and then the docking box 502 is driven to clamp and contact the workpiece, and move from the position of the baffle 7 to the position of the rotary chuck 6, so as to fully straighten the workpiece. After straightening, the movable plate 201 can be driven to drive the internal gas of the airbag 402 to be driven to be transported to the inside of the external box 401, driving the lifting plate 408 to trigger the connection switch 409, and allowing the driving source 411 and the cutting machine 414 to start descending to cut the workpiece, thereby completing the entire process of straightening and cutting the workpiece, ensuring that the curvature of the workpiece meets the standard and meets the next processing standard after entering the next process.
