Description

Technical Field

[0001] This invention relates to the field of feeding mechanisms, and particularly to a feeding mechanism for a five-axis grinding machine and its method of use. Background Technology

[0002] A grinding machine is a machine tool that uses grinding wheels to grind the surface of a workpiece. It is one of the main equipment for precision machining of machine parts. At present, grinding machines are widely used in the production or regrinding of milling, drilling, and forming tools.

[0003] Chinese patent CN223071142U discloses a feeding mechanism for a five-axis grinding machine, belonging to the field of feeding mechanisms. It includes a first conveyor belt and a second conveyor belt. A dropping table is fixedly connected to the right side of the first conveyor belt. A feeding device is provided between the top surfaces of the first and second conveyor belts. The feeding device includes a support plate, a top plate, a lead screw, a drive motor, a slide, a first cylinder, a second cylinder, a first concave seat, a first pneumatic gripper, a second concave seat, and a second pneumatic gripper. A set of symmetrical support plates is fixedly connected to the top surfaces of the first and second conveyor belts, and a top plate is fixedly connected to the top surface of the symmetrical support plates.

[0004] In the above technical solution, the length and width of the workpieces to be processed are different. Therefore, when the length and width are large, if only one clamping unit is used to clamp the workpiece, the clamping range is small and the mass of the workpiece will increase. As a result, the workpiece is prone to deflection or fall off during the feeding process. Secondly, since the surface of the unprocessed workpiece is prone to have burrs or foreign matter or impurities adhering to it during batch transportation, if there are a lot of foreign matter or burrs on the surface of the workpiece, it will seriously affect the stability of the clamping unit in clamping the workpiece, and easily cause the workpiece to fall off or tilt and deflect.

[0005] Therefore, it is necessary to solve the above problems by providing a feeding mechanism for a five-axis grinding machine and its usage method. Summary of the Invention

[0006] The purpose of this invention is to provide a loading mechanism for a five-axis grinding machine and its usage method, so as to solve the problems mentioned in the background art.

[0010] Preferably, the top of the support block is provided with a sliding block, which is used to limit the position of the support block.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] This invention provides, for example Figures 1 to 7 The loading mechanism of a five-axis grinding machine shown includes a support mechanism 1, a clamping unit 3, and an adjustment unit 2. The upper part of the support mechanism 1 is connected to the clamping unit 3 and the adjustment unit 2, respectively. The adjustment unit 2 is connected to the clamping unit 3. The adjustment unit 2 can drive the clamping unit 3 to move and be positioned in a designated loading area. In this way, the clamping unit 3 can be used to clamp the workpiece to be ground, and the adjustment unit 2 can be used to move the workpiece under clamping to the processing area, thereby realizing the workpiece transportation and loading operation.

[0023] The support mechanism 1 includes mounting plates 111, and there are at least two mounting plates 111. The two mounting plates 111 are symmetrically arranged, and a support frame 103 is provided between the two mounting plates 111. The support frame 103 is U-shaped, and its left and right sides are respectively connected to one side of the two mounting plates 111. The support frame 103 can be fixed and limited by the two symmetrically arranged mounting plates 111 and installed in the processing area of ​​the grinding machine.

[0024] Two mounting plates 111 are provided with a limiting plate 102 on the side away from the support frame 103. The two limiting plates 102 have threaded holes in the middle. The two mounting plates 111 can be positioned and installed by the limiting plates 102. Furthermore, two mounting plates 111 are provided with snap-fit ​​plates 101 on both sides away from the limiting plates 102. The snap-fit ​​plates 101 are used to cooperate with the mounting plates 111 and the limiting plates 102 to fix the support frame 103.

[0025] A feeding mechanism is provided at the center of one side of the support frame 103. The feeding mechanism includes a load-bearing base, and a connecting plate 105 is provided on the top of the load-bearing base. A drive roller 109 is passed through the center of the connecting plate 105. The outer side of the drive roller 109 is rotatably connected to the center of the connecting plate 105. A drive motor 107 is provided at either end of the drive roller 109. The drive motor 107 can drive the drive roller 109. The outer side of the drive roller 109 is connected to the outer side of the driven roller 106 via a conveyor belt. The number of connecting plates 105 is set to multiple, and each connecting plate 105 is located at the left and right ends of the driving roller 109 and the driven roller 106 respectively. The multiple connecting plates 105 can respectively limit the position of the driving roller 109 and the driven roller 106, and drive the driving roller 109 to rotate under the action of the drive shaft of the drive motor 107. At this time, as the driving roller 109 rotates, it works with the conveyor belt to rotate the driven roller 106, thereby achieving the purpose of transporting the workpiece to be processed.

[0026] The driving roller 109 and driven roller 106 are provided with protective rings 110 on the side near the connecting plate 105. The protective rings 110 are used to protect and intercept the workpiece during the conveying process, preventing the workpiece from falling off. Furthermore, there are two protective rings 110, symmetrically arranged at the left and right ends of the driving roller 109 and driven roller 106. A baffle 108 is provided between the two protective rings 110 on the side near the clamping unit 3. The baffle 108 is L-shaped. When the workpiece to be processed is placed on the surface of the conveyor belt towards the clamping unit 3... During conveying, the workpiece moves with the conveyor belt to the area of ​​the drive roller 109, and then enters the area above the baffle 108 for temporary storage. This not only maintains a stable feeding efficiency, but also effectively prevents the workpiece from piling up or overflowing. Since the baffle 108 is L-shaped, when the conveyor belt transports the workpiece to the surface of the baffle 108, it will be abutted by the side of the baffle 108 near the clamping unit 3. The subsequent workpieces will be arranged behind the workpieces abutting the side of the baffle 108, and with the cooperation of the baffle 108 and the two protective rings 110, they will form a linear arrangement on the baffle 108 and the conveyor belt.

[0027] On the other side of the support frame 103, in the middle area corresponding to the feeding mechanism, there is a discharge mechanism. The discharge mechanism includes a drive roller 109, a driven roller 106, a conveyor belt, a protective ring 110, a connecting plate 105, and a load-bearing plate 104. The assembly method of the drive roller 109, driven roller 106, conveyor belt, protective ring 110, connecting plate 105, and load-bearing plate 104 is the same as that of the feeding mechanism. The discharge mechanism is used to cooperate with the clamping unit 3 to transport the processed workpiece to the next process.

[0028] The adjustment unit 2 includes a transmission screw 202, which is located inside the support frame 103 on the side near the top. The transmission screw 202 passes through the support frame 103, and a circumferential drive device 201 is provided at either end of the transmission screw 202. The circumferential drive device 201 can drive the transmission screw 202 to rotate inside the support frame 103. The circumferential drive device 201 can be a rotary motor or an electric motor. A support block 203 is threaded on the outer surface of the transmission screw 202. A sliding block 206 is provided on the top of the support block 203. The support block 203 is slidably disposed on the top of the inner side of the support frame 103 through the sliding block 206. The sliding block 206 can slide horizontally along the top of the inner wall of the support frame 103.

[0029] The clamping unit 3 includes a fixing frame 204 located below the telescopic rod. An adjusting block is provided at the bottom of the fixing frame 204, and the adjusting block is slidably disposed at the bottom of the fixing frame 204. A hydraulic cylinder 205 is provided at the bottom of the adjusting block. The output end of the hydraulic cylinder 205 is fixedly connected to a loading housing 304. A linear drive device 302 is provided at the top of the loading housing 304. A stabilizing plate 303 is provided on the outer surface of the linear drive device 302. The linear drive device 302 is fixedly connected to the outer top of the loading housing 304 via the stabilizing plate 303. The output end of the linear drive device 302 penetrates through the loading housing 304. Inside the linear drive device 302, the output end of the linear drive device 302 is provided with a clamping plate 301. The clamping plate 301 can move horizontally at the bottom of the fixed frame 204 in cooperation with the linear drive device 302. The clamping plate 301, the linear drive device 302 and the stabilizing plate 303 are symmetrically arranged on the left and right sides of the loading housing 304. The two clamping plates 301 can move horizontally inside the fixed frame 204 in cooperation with the two linear drive devices 302. When the two linear drive devices 302 are in a synchronous extension state, the distance between the two clamping plates 301 is close to each other. When the two clamping plates 301 contact the two sides of the workpiece, the workpiece can be clamped and fixed.

[0030] Secondly, the number of clamping units 3 is set to two, and the two clamping units 3 are symmetrically arranged inside the support frame 103. An electric push rod 306 is provided between the two clamping units 3. The output end of the electric push rod 306 is connected to the loading housing 304 in any one of the clamping units 3. When the electric push rod 306 is in the extended state, the distance between the two clamping units 3 gradually increases. When the electric push rod 306 is in the retracted state, the distance between the two clamping units 3 gradually decreases.

[0031] The loading housing 304 has a negative pressure structure on the side near the adjusting block. The negative pressure structure includes a negative pressure hole 307 and an air extraction pipe 305. The air extraction pipe 305 is located on one side of the loading housing 304 and is connected to an external air pump (not shown in the figure). The external air pump generates suction on the surface of the workpiece through the negative pressure hole 307. When the workpiece is clamped and fixed by the two clamping plates 301 in the loading housing 304, the top of the workpiece can be made to fit against the bottom of the loading housing 304. In this way, the loading housing 304, together with the negative pressure structure, can generate negative pressure between itself and the workpiece. In turn, the clamping plates 301 can stably clamp and transport the workpiece. The external air pump is a common electric pump, and the electric pump has two working modes: one is the suction state, and the other is the blowing state. Since the electric pump is a common existing device, it will not be described in detail here.

[0032] In use, firstly, multiple mounting plates 111 and limiting plates 102 are used in conjunction with threaded holes to fix the support frame 103, so that the support frame 103 is located in the working area. Then, the workpiece to be processed is placed on the surface of the conveyor belt in the feeding mechanism. In this way, the workpiece to be processed is conveyed towards the clamping unit 3 through the mutual cooperation of the driving roller 109 and the driven roller 106. When the workpiece to be processed moves to the surface of the baffle 108 with the help of the conveyor belt, the risk of the workpiece falling off during transportation can be avoided by the protective ring 110. Then, the circumferential drive device 201 drives the support block 203 to move horizontally along the surface of the transmission screw 202 under the limiting action of the sliding block 206. In this way, the circumferential drive device 201 moves the support plate to the area above the baffle 108. Then, the hydraulic push rod is activated and is in the extended state.

[0033] As the hydraulic push rod extends, it drives the loading housing 304 to gradually approach the lower baffle 108. Two linear drive devices 302 simultaneously drive the clamping plates 301 to move horizontally along the interior of the loading housing 304, causing them to gradually approach and contact the outer surface of the workpiece, thus forming a clamp. During this clamping process, the bottom of the outer surface of the loading housing 304 contacts the top of the outer surface of the workpiece. Then, an external air pump creates a negative pressure between the bottom of the loading housing 304 and the workpiece. With the clamping action of the two clamping plates 301, the workpiece is stably positioned between them. Simultaneously, the circumferential drive device 201, in conjunction with the transmission screw 202, transports the workpiece to the central processing area.

[0034] Furthermore, since there are two clamping units 3, in the initial state, the clamping operation described above allows both clamping units 3 to simultaneously clamp and transport two workpieces. The electric push rod 306 between the two clamping units 3, in conjunction with the adjusting block, moves horizontally within the fixed frame 204, thereby adjusting the distance between the two clamping units 3. When the workpiece in one clamping unit 3 is finished, the clamping unit 3 is used again to clamp the finished workpiece. Then, the circumferential drive device 201, in conjunction with the transmission screw 202, drives the support block 203 and the sliding block 206 to move the two clamping units 3 towards the discharge mechanism while maintaining a certain distance, thus positioning the other clamping unit 3... In the processing area, the completed workpiece and clamping unit 3 are located above the discharge mechanism. The completed workpiece is then placed on the conveyor belt in the discharge mechanism, and another clamping unit 3 is controlled to place the unfinished workpiece in the processing area, so that the discharge and feeding processes are kept at a synchronous speed. Then, the circumferential drive device 201 drives the support plate and sliding block 206 to move to the initial feeding position, so that one clamping unit 3 is located in the processing area and the other clamping unit 3 is located above the feeding mechanism. After processing is completed, it is only necessary to clamp synchronously and always keep the two clamping units 3 at the same feeding and discharging speed, so as to achieve uninterrupted feeding and discharging, thereby improving the feeding and discharging efficiency.

[0035] Although the negative pressure structure at the bottom of the loading housing 304, in conjunction with two linear drive devices 302 and two clamping plates 301, can achieve fixed clamping and loading of the outer surface of the workpiece, the length and width specifications of the unprocessed workpieces vary. Therefore, when the length and width specifications are large, relying solely on one clamping unit 3 to clamp the workpiece results in a small clamping range and an increased workpiece mass. Consequently, during the loading process, the workpiece is prone to deflection or falling off while being clamped by the clamping unit 3. Based on this, the adjustment scheme is as follows: A displacement sensor is installed at the end of the electric push rod 306, and a pressure sensor is installed at the end of the air extraction pipe 305 in the negative pressure mechanism. By using the cooperation of the displacement sensor and the pressure sensor, the size of the workpiece can be determined. This allows for the corresponding adjustment of the feeding strategy of the clamping unit 3 based on the detected data, ensuring that workpieces of different sizes can be clamped and fed.

[0036] When clamping and feeding workpieces with large length and width specifications, the circumferential drive device 201 drives the support block 203 and sliding block 206 to move above the workpiece. Then, the hydraulic push rods in the two clamping units 3 control the two feeding housings 304 and multiple clamping plates 301 to move towards the workpiece, so that the bottom of the multiple clamping plates 301 contacts one side surface of the workpiece. At this time, the bottom of the feeding housing 304 is always in contact with the top of the outer side of the workpiece. Then, the electric push rod 306 is gradually extended, so that the distance between the two clamping units 3 gradually increases. This allows the multiple clamping plates 301 to move along one side surface of the workpiece. At the same time, during the movement, the air pressure sensor in the negative pressure structure detects the negative pressure data in real time. Then, the displacement sensor in the electric push rod 306 can be used to determine the specification data of the workpiece. After the electric push rod 306 drives the two clamping units 3 to move along the outer surface of the workpiece to a suitable position, the multiple linear drive devices 302 are simultaneously controlled to cooperate with the multiple clamping plates 301 to achieve the effect of clamping and feeding workpieces of different specifications.

[0037] Secondly, since burrs are easily left on the surface of unprocessed workpieces, or foreign matter or impurities may adhere to them during batch transportation, the presence of a large amount of foreign matter or burrs on the surface of the workpiece will seriously affect the stability of the clamping unit 3 in clamping the workpiece, and may easily cause the workpiece to fall off or tilt. Therefore, a strain acquisition device (not shown in the figure, but the strain acquisition device is a common strain gauge structure) is provided on the surface of each clamping plate 301 in conjunction with a pressure sensor (not shown in the figure) to detect the contact pressure between the clamping plate 301 and the workpiece in real time, thereby determining the contact pressure between the clamping plate 301 and the workpiece. Whether the data is normal is ensured to guarantee that the clamping unit 3 can always maintain normal contact pressure data for loading the workpiece. Therefore, during the surface specification measurement of larger workpieces, since one side of the clamping plate 301 is always in contact with the surface of the workpiece, the stress data collected by the strain acquisition device will change when there are burrs or foreign objects on the outer surface of the workpiece. Thus, real-time detection of the workpiece surface flatness is achieved. If a large number of burrs or foreign impurities are detected on the workpiece surface, the electric push rod 306 is used to extend or retract, so that the clamping plate 301 in one of the clamping units 3 is positioned... In areas with foreign objects or burrs, the linear drive device 302 controls the clamping plate 301 to maintain close contact with the workpiece. Then, the linear drive device 302 in another clamping unit 3 drives the clamping plate 301 to fix and clamp the other side of the workpiece, ensuring that the clamping force generated is higher than that of the other clamping units 3 where foreign objects or burrs are present. At this point, the electric push rod 306 is controlled again to frequently retract and extend over short distances. This allows the clamping unit 3 with the higher clamping force to drive the workpiece in a horizontal reciprocating motion as the electric push rod 306 extends or retracts. Meanwhile, the other... The clamping plate 301 in the clamping unit 3 will frequently rub against the workpiece surface in the foreign matter burr area, thereby cleaning the foreign matter burrs on the workpiece surface. During this process, the distance of the electric push rod 306 frequently extending or retracting can be used to adjust the area of ​​the clamping plate 301 used to clean the impurities or burrs on the outer surface of the workpiece, and achieve the effect of cleaning foreign matter impurities or burrs in different ranges. Finally, the negative pressure structure at the bottom of the loading shell 304 is used to blow the burrs or impurities off towards the surface of the workpiece, so as to prevent the cleaned burrs or impurities from still adhering to the surface of the workpiece.

[0038] If the stress acquisition equipment detects a small number of burrs and foreign objects, the circumferential drive device 201 only needs to move the support block 203 and the sliding block 206 above the workpiece. Then, the hydraulic push rod only needs to move the clamping plate 301 in the clamping unit 3 above the area with burrs. Then, the extension and retraction of the hydraulic push rod only needs to be controlled to drive the clamping plate 301 to longitudinally cut the burr or foreign object area on the workpiece surface. During this process, another clamping unit 3, in conjunction with the linear drive device 302 and the clamping plate 301, clamps and fixes the other side of the workpiece. This avoids the burrs or foreign objects on the outside of the workpiece being cleaned. Finally, the negative pressure structure at the bottom of the loading shell 304 blows the burrs or foreign objects onto the surface of the workpiece, preventing the cleaned burr fragments or impurities from still adhering to the surface of the workpiece, which could cause the workpiece to shift or fall off.

[0039] In addition, after the workpiece is processed, its surface is usually covered with a lot of machining debris. Therefore, in order to avoid the workpiece being damaged or scratched due to the presence of debris on its surface during clamping (there is a lot of debris between the clamping plate 301 and the workpiece surface, and the force-bearing area will shrink when pressure is applied, thus causing damage or scratches), which would affect subsequent product processes, the circumferential drive device 201 is activated in conjunction with the hydraulic push rod to position the two clamping units 3 above the workpiece. Then, the negative pressure structure under the loading housing 304 in the two clamping units 3 is used to generate pressure on the workpiece. The working mode is directional blowing, and the negative pressure hole 307 is used to blow up and clean the machining debris on the surface of the workpiece. Secondly, during the process, two linear drive devices 302 control multiple clamping plates 301 to wipe along the outer surface of the workpiece. During this process, the linear drive devices 302 control the clamping plates 301 to be in slight contact with the surface of the workpiece. This, together with the wiping of the clamping plates 301 and the air blown out by the negative pressure structure, achieves the purpose of cleaning the outer machining debris, avoiding the occurrence of a large number of pressure marks and scratches during subsequent clamping and unloading.
