Description

Technical Field

[0001] The invention relates to the technical field of drilling, in particular to a drilling device for producing magnesium alloy telescopes with a cut grinding function. Background Art

[0002] As an optical instrument, a telescope observes distant objects through lenses and reflectors. With the continuous development of manufacturing technology, various alloy materials have been used to greatly improve the service life of telescopes. Among them, the basic materials of telescopes include aluminum alloy, magnesium alloy and aluminum-magnesium alloy.

[0003] In addition to strict requirements on the metal body of the telescope, the quality requirements on the lens body are even more stringent. Some large telescopes require a primary mirror during use, and the primary mirror needs to be punched during the production process. Different from the holes drilled on the metal body, the holes drilled on the metal body are mainly installation holes, which do not require high molding technology. As a high-precision optical instrument, the primary mirror has high molding quality requirements. After the conventional punching device completes the drilling, the primary mirror needs to be transferred to other stations for polishing, and it is impossible to perform drilling and polishing at the same time.

[0004] In addition, when drilling holes in lenses of different specifications, the tool disc can be used to automatically change the tool, but the grinding diameter cannot be automatically adjusted according to different apertures. Summary of the invention

[0005] The object of the present invention is to provide a punching device for magnesium alloy telescope production with a cut grinding function to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A punching device for producing magnesium alloy telescopes with a cut grinding function, the punching device is used to cut holes in a workpiece, the punching device comprises a bed, a power device, a grinding device and a clamping device, the power device is connected to the bed, the clamping device is tightly connected to the bed, the clamping device and the power device are arranged facing each other, the grinding device is connected to the power device, and the grinding device is used to automatically grind the cut of the workpiece.

[0008] The bed serves as the main supporting base for installing other devices. An open or closed space can be used. The power device serves as the main hole cutting device. The workpiece is clamped by the clamping device and driven to rotate. During the rotation of the workpiece, the power device automatically cuts holes. After the hole cutting is completed, the incision is automatically polished by the grinding device to improve the forming efficiency. The clamping device and the power device are arranged opposite to each other to perform horizontal hole cutting, which is convenient for setting up a cooling device and flushing away the cutting.

[0009] Furthermore, the power device includes a linear module, a slide and a hollow drill bit, the fixed end of the linear module is tightly connected to the bed, the movable end of the linear module is tightly connected to the slide, a transmission shaft is provided on the side of the slide facing the clamping device, a hollow drill bit is provided on the end of the transmission shaft away from the slide, and the transmission shaft is connected to the grinding device;

[0010] The clamping device comprises a driving motor and a chuck. The driving motor is firmly connected to the bed, the output end of the driving motor is transmission-connected to the chuck, and the chuck is used to clamp the workpiece.

[0011] By setting a linear module to provide linear displacement, the linear module can adopt an existing screw-nut substructure to improve the stability of displacement output. The linear module outputs displacement, which can be used to drive the hollow drill bit to move. At the same time, a driving motor fixed on the bed outputs torque to drive the chuck to rotate. The chuck is used to clamp the workpiece, thereby driving the workpiece to rotate through the chuck, so that the cutting edge of the hollow drill bit cuts a hole in the middle of the workpiece. The transmission shaft is used to drive the grinding device to move. When the hole cutting is completed, the drill bit passes through the through hole on the workpiece through the linear module, so that the grinding device enters the through hole and automatically grinds the wall of the through hole.

[0012] Furthermore, the grinding device includes an induction component, which is movably connected to the transmission shaft. The induction component includes a mounting seat, a pre-stress spring, a guide rod and a grinding head. The transmission shaft is circumferentially provided with a plurality of expansion grooves. One end of the mounting seat is in contact with the expansion groove. The mounting seat is provided with an induction groove. A coil is provided in the induction groove. A pre-stress spring is sleeved on the outer ring of the guide rod. The side of the pre-stress spring away from the contact end of the guide rod is tightly connected to the induction groove. The guide rod is inserted into the inner ring of the coil. A grinding head is provided on the outer side of the guide rod. The grinding head is used to grind the hole wall of the workpiece. The guide rod is made of a magnet.

[0013] The grinding device grinds the through hole on the workpiece by setting an induction component, and automatically adjusts the grinding time to ensure the uniformity of grinding. The mounting seat is installed through the expansion slot on the transmission shaft. The guide rod is abutted against the induction slot through a pre-compression spring, one end of which is inserted into the coil and the other end is connected to the grinding head. Under the action of the pre-compression spring, the grinding head is pressed against the through hole wall of the workpiece. When the workpiece is driven to rotate by the chuck, the grinding head automatically grinds the through hole wall of the workpiece. During the grinding process, the through hole wall of the workpiece applies friction resistance to the grinding head. The guide rod is driven to slide along the induction slot by the grinding head. The axes of the induction slot and the transmission shaft coincide. The guide rod is arranged in an arc shape and the axes are kept collinear. When the guide rod slides along the induction slot, it rotates along the axis of the transmission shaft, and an induced current is generated on the coil. The rotation angle of the guide rod is positively correlated with the roughness of the through hole wall of the workpiece, that is, the greater the roughness, the greater the rotation angle of the guide rod, and the greater the induced current passing through the coil, thereby performing real-time detection of the through hole wall roughness of the workpiece.

[0014] Furthermore, the expansion groove is arranged in an arc shape, the curvature of the expansion groove changes gradually, the end of the expansion groove close to the grinding head faces the hole wall of the workpiece, the curvature of the expansion groove gradually decreases from the end far from the grinding head to the end close to the grinding head, and the mounting seat and the expansion groove are slidably connected.

[0015] By setting the expansion groove with a gradually changing arc shape, the mounting seat is in two-point contact in the expansion groove, with the point with the smallest curvature as the starting point and the point with the largest curvature as the end point. The outer side of the starting point and the inner side of the end point are in contact with the wall surface of the expansion groove respectively. The contact end of the mounting seat is set in an arc shape to improve sliding smoothness.

[0016] Furthermore, the grinding device also includes a flaring assembly, which includes an expansion motor and a lever, a drive cavity is provided on the transmission shaft, the expansion motor is placed in the drive cavity, a plurality of levers are provided at the output end of the expansion motor, the drive cavity is connected to a plurality of expansion slots, a transmission slot is provided on the mounting seat, and the lever is inserted into the transmission slot at one end away from the expansion motor;

[0017] When expanding: the lever and the transmission groove are slidably connected.

[0018] The expansion motor is installed through the driving cavity. The expansion motor is used to output torque to drive the lever to rotate. When grinding the through-hole wall surfaces of workpieces of different specifications, the lever is inserted into the transmission groove of the mounting seat. Through the gradual curvature setting of the expansion groove, when the lever drives the mounting seat to rotate outward, the mounting seat is pushed to slide along the expansion groove. At the same time, the mounting seat moves outward along the lever, thereby driving the grinding radius of the grinding head to increase; conversely, the expansion motor reverses to reduce the grinding radius.

[0019] Furthermore, there are two mounting seats, two driving cavities are provided, and an expansion motor is respectively arranged in the two driving cavities.

[0020] By setting up two mounting seats, each mounting seat is driven to expand by an expansion motor, and the two mounting seats can be arranged in a staggered manner. The grinding range of one grinding head is one unit grinding surface. Through the staggered arrangement, two unit grinding surfaces can be polished at the same time, thereby improving the grinding efficiency.

[0021] Furthermore, the guide rod and the coil constitute an adjustment circuit, and the expansion motor is electrically connected to the adjacent adjustment circuit.

[0022] By setting the adjustment circuit, the force of the guide rod crimping preload spring is mainly the friction resistance exerted by the wall of the workpiece through hole. As the grinding progresses, the friction resistance decreases, and the preload spring pushes the guide rod outward, generating a reverse current on the coil. When the reverse current is stable, the grinding is completed, and the incision grinding is automatically completed. The linear module drives the transmission shaft to move linearly to perform the next level of grinding. When two unit grinding surfaces are being ground at the same time, due to the different roughness of the incisions and different grinding times, the expansion motor is driven to drive the mounting seat to retract according to the current change of the adjustment circuit. That is, when a unit grinding surface is finished, the reverse current of the adjustment circuit here is stable, and the mounting seat is retracted by the adjacent expansion motor of the adjustment circuit here, so that the grinding radius of the grinding head is reduced, and it no longer contacts the wall of the workpiece through hole until the next level of grinding is performed and then extended, reducing energy consumption.

[0023] As an optimization, the power device also includes a traverse motor, which is firmly connected to the bed, and the output end of the traverse motor is connected to the linear module. The traverse motor is the main driving force of the linear module, which is used to drive the linear module to output linear displacement, so as to facilitate cutting and grinding.

[0024] As an optimization, the clamping device also includes a support platform, the support platform is tightly connected to the bed, a support groove is provided on the upper end of the support platform, and the chuck is rotatably connected to the support groove. By setting the support platform and installing it on the bed, the chuck is supported by the support groove, thereby improving the rotation stability of the chuck.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: in the process of driving the workpiece to rotate by the chuck, the grinding head automatically grinds the through-hole wall surface of the workpiece; in the grinding process, the through-hole wall surface of the workpiece applies friction resistance to the grinding head, and the grinding head drives the guide rod to slide along the induction groove; the axes of the induction groove and the transmission shaft coincide; the guide rod is arranged in an arc shape, and the axes are also kept collinear, so that when the guide rod slides along the induction groove, it rotates along the axis of the transmission shaft, and an induced current is generated on the coil; the rotation angle of the guide rod is positively correlated with the roughness of the through-hole wall surface of the workpiece, that is, the greater the roughness, the greater the rotation angle of the guide rod, and the greater the induced current passing through the coil, thereby performing real-time detection of the roughness of the through-hole wall surface of the workpiece; when grinding the through-hole wall surfaces of workpieces of different specifications, the lever is inserted into the transmission groove of the mounting seat, and the curvature of the expansion groove is gradually changed. When the lever drives the mounting seat to rotate outward When the expansion motor is turned on, the mounting seat is pushed to slide along the expansion slot, and the mounting seat moves outward along the lever, thereby increasing the grinding radius of the grinding head; conversely, the expansion motor is reversed to reduce the grinding radius; the two mounting seats can be arranged in a staggered manner, and the grinding range of one grinding head is one unit grinding surface. Through the staggered arrangement, two unit grinding surfaces can be polished at the same time, thereby improving the grinding efficiency; when two unit grinding surfaces are being polished at the same time, due to different incision roughness and different grinding times, the expansion motor is driven to drive the mounting seat to retract according to the current change of the adjustment circuit, that is, when a unit grinding surface is polished, the reverse current of the adjustment circuit here is stable, and the mounting seat is retracted through the adjacent expansion motor of the adjustment circuit here, thereby reducing the grinding radius of the grinding head and no longer contacting the wall of the through hole of the workpiece until the next level of polishing is performed and then extended, thereby reducing energy consumption.

[0035] Example: Figure 1-Figure 7 As shown, the present invention provides a technical solution for a punching device for producing magnesium alloy telescopes with a cut grinding function.

[0037] The bed serves as the main supporting base for installing other devices, and an open or closed space can be used. The power device 2 serves as the main hole cutting device, and the workpiece 5 is clamped by the clamping device 4, and the workpiece 5 is driven to rotate. During the rotation of the workpiece 5, the power device 2 automatically cuts holes. After the hole cutting is completed, the incision is automatically polished by the grinding device 3 to improve the forming efficiency. The clamping device 4 and the power device 2 are arranged opposite to each other, and horizontal hole cutting is performed, which is convenient for setting up a cooling device and flushing away the cutting.

[0038] Furthermore, the power device 2 includes a linear module 22, a slide 23 and a hollow drill bit 25. The fixed end of the linear module 22 is tightly connected to the bed 1, and the movable end of the linear module 22 is tightly connected to the slide 23. The slide 23 is provided with a transmission shaft 24 on the side facing the clamping device 4. The transmission shaft 24 is provided with a hollow drill bit 25 at one end away from the slide 23. The transmission shaft 24 is connected to the grinding device 3.

[0039] The clamping device 4 includes a driving motor 41 and a chuck 42 . The driving motor 41 is firmly connected to the bed 1 . The output end of the driving motor 41 is drivingly connected to the chuck 42 . The chuck 42 is used to clamp the workpiece 5 .

[0040] By setting up a linear module 22 to provide linear displacement, the linear module 22 can adopt an existing screw-nut substructure to improve the stability of displacement output. The linear module 22 outputs displacement, which can be used to drive the hollow drill bit 25 to move. At the same time, a torque is output through a drive motor 41 fixed on the bed 1 to drive the chuck 42 to rotate. The chuck 42 is used to clamp the workpiece 5, thereby driving the workpiece 5 to rotate through the chuck 42, so that the cutting edge of the hollow drill bit 25 cuts a hole in the middle of the workpiece 5. The transmission shaft 24 is used to drive the grinding device 3 to move. When the hole cutting is completed, the drill bit passes through the through hole on the workpiece 5 through the linear module 22, so that the grinding device 3 enters the through hole and automatically grinds the wall of the through hole.

[0041] Furthermore, the grinding device 3 includes an induction component 31, which is movably connected to the transmission shaft 24. The induction component 31 includes a mounting seat 311, a pre-stress spring 313, a guide rod 314 and a grinding head 315. The transmission shaft 24 is circumferentially provided with a plurality of expansion grooves 242. One end of the mounting seat 311 is in contact with the expansion groove 242. The mounting seat 311 is provided with an induction groove 3111, and a coil 312 is provided in the induction groove 3111. The outer ring of the guide rod 314 is sleeved with a pre-stress spring 313, and the side of the pre-stress spring 313 away from the contact end of the guide rod 314 is tightly connected to the induction groove 3111. The guide rod 314 is inserted into the inner ring of the coil 312. A grinding head 315 is provided on the outer side of the guide rod 314. The grinding head 315 is used to grind the hole wall of the workpiece 5. The guide rod 314 is made of magnet material.

[0042] The grinding device 3 grinds the through hole on the workpiece 5 by setting the induction component 31, and automatically adjusts the grinding time to ensure the uniformity of grinding. The mounting seat 311 is installed through the expansion slot 242 on the transmission shaft 24. The guide rod 314 is abutted against the induction slot 3111 through the pre-compression spring 313, one end of which is inserted into the coil 312, and the other end is connected to the grinding head 315. Under the action of the pre-compression spring 313, the grinding head 315 is pressed against the through hole wall of the workpiece 5. During the process of driving the workpiece to rotate by the chuck 42, the grinding head 315 automatically grinds the through hole wall of the workpiece 5. During the grinding process, the through hole wall of the workpiece 5 When friction resistance is applied to the grinding head 315, the grinding head 315 drives the guide rod 314 to slide along the sensing groove 3111. The axis of the sensing groove 3111 and the transmission shaft 24 coincide with each other. The guide rod 314 is arranged in an arc shape and the axis is also kept collinear. When the guide rod 314 slides along the sensing groove 3111, it rotates along the axis of the transmission shaft 24, and an induced current is generated on the coil 312. The rotation angle of the guide rod 314 is positively correlated with the roughness of the wall surface of the through hole of the workpiece 5. That is, the greater the roughness, the greater the rotation angle of the guide rod 314, and the greater the induced current passing through the coil 312, thereby performing real-time detection of the roughness of the wall surface of the through hole of the workpiece 5.

[0043] Furthermore, the expansion groove 242 is arranged in an arc shape, and the curvature of the expansion groove 242 changes gradually. The end of the expansion groove 242 close to the grinding head 315 faces the hole wall of the workpiece 5, and the curvature of the expansion groove 242 gradually decreases from the end far from the grinding head 315 to the end close to the grinding head 315, and the mounting seat 311 and the expansion groove 242 are slidably connected.

[0044] Through the arc setting with gradual curvature of the expansion groove 242, the mounting seat 311 is in two-point contact in the expansion groove 242, with the minimum curvature as the starting point and the maximum curvature as the end point. The outer side of the starting point and the inner side of the end are in contact with the wall surface of the expansion groove 242 respectively. The contact end of the mounting seat 311 adopts an arc setting to improve sliding smoothness.

[0045] Furthermore, the grinding device 3 also includes a flaring assembly 32, which includes an expansion motor 321 and a lever 322. A driving cavity 241 is provided on the transmission shaft 24, and the expansion motor 321 is placed in the driving cavity 241. A plurality of levers 322 are provided at the output end of the expansion motor 321. The driving cavity 241 is connected to a plurality of expansion slots 242. A transmission slot 3112 is provided on the mounting seat 311, and an end of the lever 322 away from the expansion motor 321 is inserted into the transmission slot 3112.

[0046] During expansion: the lever 322 and the transmission groove 3112 are slidably connected.

[0047] The expansion motor 321 is installed through the driving chamber 241. The expansion motor 321 is used to output torque to drive the lever 322 to rotate. When grinding the through-hole wall of the workpiece 5 of different specifications, the lever 322 is inserted into the transmission groove 3112 of the mounting seat 311. Through the gradual curvature setting of the expansion groove 242, when the lever 322 drives the mounting seat 311 to rotate outward, the mounting seat 311 is pushed to slide along the expansion groove 242. At the same time, the mounting seat 311 moves outward along the lever 322, thereby driving the grinding radius of the grinding head 315 to increase; conversely, the expansion motor 321 reverses to reduce the grinding radius.

[0048] Furthermore, there are two mounting seats 311 , two driving cavities 241 are provided, and an expansion motor 321 is respectively disposed in the two driving cavities 241 .

[0049] By setting up two mounting seats 311, each mounting seat 311 is driven to expand by an expansion motor 321, and the two mounting seats 311 can be arranged in a staggered manner. The grinding range of a grinding head 315 is a unit grinding surface. Through the staggered arrangement, two unit grinding surfaces can be polished at the same time, thereby improving the grinding efficiency.

[0050] Furthermore, the guide rod 314 and the coil 312 form an adjustment circuit, and the expansion motor 321 is electrically connected to the adjacent adjustment circuit.

[0051] By setting the adjustment circuit, the force of the guide rod 314 pressing the preload spring 313 is mainly the friction resistance applied by the wall of the through hole of the workpiece 5. As the grinding progresses, the friction resistance decreases, and the preload spring 313 pushes the guide rod 314 to move outward, generating a reverse current on the coil 312. When the reverse current is stable, the grinding is completed, and the incision grinding is automatically completed. The linear module 22 drives the transmission shaft 24 to move linearly to perform the next level of grinding. When two unit grinding surfaces are being ground at the same time, due to the different roughness of the incisions and different grinding times, according to the current change of the adjustment circuit, the expansion motor 321 is driven to drive the mounting seat 311 to retract, that is, when a unit grinding surface is finished, the reverse current of the adjustment circuit here is stable, and the mounting seat 311 is driven to retract by the adjacent expansion motor 321 of the adjustment circuit here, so that the grinding radius of the grinding head 315 is reduced, and it no longer contacts the wall of the through hole of the workpiece 5 until the next level of grinding is performed and then extended, reducing energy consumption.

[0052] As an optimization, the power device 2 also includes a traverse motor 21, which is firmly connected to the bed 1, and the output end of the traverse motor 21 is transmission-connected to the linear module 22. The traverse motor 21 is the main driving force of the linear module 22, and is used to drive the linear module 22 to output linear displacement, which is convenient for cutting and grinding.

[0053] As an optimization, the clamping device 4 also includes a support platform 43, which is tightly connected to the bed 1, and a support groove is provided at the upper end of the support platform 43, and the chuck 42 is rotatably connected to the support groove. By providing the support platform 43, which is installed on the bed 1, the chuck 42 is supported by the support groove, thereby improving the rotation stability of the chuck 42.

[0054] The working principle of the present invention is as follows: when the chuck 42 drives the workpiece to rotate, the grinding head 315 automatically grinds the through-hole wall surface of the workpiece 5. During the grinding process, the through-hole wall surface of the workpiece 5 applies friction resistance to the grinding head 315, and the grinding head 315 drives the guide rod 314 to slide along the induction groove 3111. The induction groove 3111 and the axis of the transmission shaft 24 coincide with each other. The guide rod 314 is arranged in an arc shape, and the axis is also kept in a colinear manner, so that when the guide rod 314 slides along the induction groove 3111, it rotates along the axis of the transmission shaft 24, and an induced current is generated on the coil 312. The rotation angle of the guide rod 314 is positively correlated with the roughness of the through-hole wall surface of the workpiece 5, that is, the greater the roughness, the greater the rotation angle of the guide rod 314, and the greater the induced current passing through the coil 312, thereby performing real-time detection of the through-hole wall surface roughness of the workpiece 5; when grinding the through-hole wall surfaces of workpieces 5 of different specifications, the lever 322 Inserted into the transmission groove 3112 of the mounting seat 311, through the curvature gradient setting of the expansion groove 242, when the lever 322 drives the mounting seat 311 to rotate outward, the mounting seat 311 is pushed to slide along the expansion groove 242, and the mounting seat 311 moves outward along the lever 322, thereby driving the grinding radius of the grinding head 315 to increase; conversely, the expansion motor 321 is reversed to reduce the grinding radius; the two mounting seats 311 can be arranged in a staggered manner, and the grinding range of one grinding head 315 is one unit grinding surface. Through the staggered arrangement, two single grinding surfaces can be ground at the same time. The grinding surface is positioned to improve the grinding efficiency; when two unit grinding surfaces are being ground at the same time, due to the different roughness of the cuts and the different grinding times, the expansion motor 321 is driven to drive the mounting seat 311 to retract according to the current change of the adjustment circuit, that is, when a unit grinding surface is ground, the reverse current of the adjustment circuit here is stable, and the mounting seat 311 is driven to retract through the adjacent expansion motor 321 of the adjustment circuit here, thereby reducing the grinding radius of the grinding head 315 and no longer contacting the wall of the through hole of the workpiece 5 until the next level of grinding is carried out, thereby reducing energy consumption.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
