Description

Technical Field

[0001] The invention relates to the technical field of positioning, in particular to an adjustable positioning device for machining a bearing gear ring. Background Art

[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. When other components in the device produce relative motion on the shaft, bearings are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. They are widely seen in mechanical equipment.

[0003] The patent with patent announcement number CN215238334U discloses an adjustable positioning device for bearing gear ring processing, including a processing disk and a toothed wheel disk. A movable bearing is connected through the center of the inner cavity of the processing disk, and a toothed wheel disk is sleeved in the middle of the movable bearing. A limiting block is slidably connected inside the limiting groove, and a fixed block is fixedly installed on the top of the limiting block by screws. A fixed groove is opened in the middle of the outer side of the processing disk, and a hydraulic device is movably connected inside the fixed groove; this patent controls the hydraulic device to push the limiting block to slide in the limiting groove, thereby realizing that two L-shaped rods push and pull two second positioning blocks and two second sliding blocks to slide in the second slot, and the two second positioning blocks and the first positioning block form a circular positioning device, which solves the problem that the positioning device does not have good adjustability during the processing of the bearing gear ring, resulting in no good positioning device when processing bearing gear rings of different diameters.

[0004] However, the device still has some shortcomings: the device can position and adjust the bearing, but in the process of carving the bearing teeth, some parts of the positioning device need to be disassembled for orientation adjustment, which is easy to increase the energy consumption of the staff and reduce the processing efficiency for the long-term bearing processing process. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an adjustable positioning device for machining a bearing gear ring, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an adjustable positioning device for bearing gear ring processing, comprising a base, support columns are arranged at the four corners of the bottom of the base, a motor is arranged at the center of the bottom of the base, a transmission rod is arranged at the center of the top of the base, the bottom of the transmission rod passes through and is fixedly installed on the top of the motor output end, a toothed disk is fixedly installed on the outer wall of the transmission rod, the bottom of the toothed disk is in contact with the top surface of the base, a plurality of elastic arc strips are fixedly installed between the top of the toothed disk and the outer wall of the transmission rod, the plurality of elastic arc strips are equidistantly distributed on the outer wall of the transmission rod, and the angle between the elastic arc strip and the outer wall of the transmission rod gradually increases from top to bottom, and the base A processing ring is fixedly installed on the top, and two fixed plates are fixedly installed on the top edge of the base, and the two fixed plates are symmetrically distributed with respect to the axis of the base. An electric push rod is fixedly installed on one side of the fixed plate close to the center of the base, and the electric push rod is composed of a fixed end and a telescopic end. The outer wall of the telescopic end of the electric push rod movably penetrates the interior of the processing ring, and an arc-shaped splint is fixedly installed on the telescopic end of the electric push rod close to the center of the base. The outer wall of the arc-shaped splint fits with the inner groove of the processing ring, and a protective plate is fixedly installed on the outer wall of the telescopic end of the electric push rod, and a mirror panel is slidably installed inside the protective plate. The mirror panel is hinged with an inclined rod on one side close to the center of the base, so that the central circular hole of the workpiece is moved from above the transmission rod and with the transmission rod. The rod is placed downward with the center as the center, and the workpiece is placed downward to the periphery of the outer wall of the transmission rod from the center circular hole of the workpiece, the inner wall of the workpiece contacts the inner wall of the elastic arc strip and generates a resistance force. The elastic arc strip is deformed by the resistance force, and the workpiece continues to descend. At this time, the extrusion pressure borne by the arc surface of the outer wall of the elastic arc strip continues to increase until the workpiece falls to the top of the toothed disk, and the outside of the workpiece is located in the internal range of the machining ring. At the same time, during the cutting and grinding rotation of the workpiece gear ring, the motor is started, and the output end of the motor drives the transmission rod to rotate, and the transmission rod rotates to drive the toothed disk to rotate, and the toothed disk rotates to drive the workpiece to rotate for azimuth adjustment; when the workpiece is placed, the electric push rod is started, the fixed plate limits the electric push rod, and the telescopic end of the electric push rod drives the arc The arc-shaped splint moves toward the center of the toothed disk, and the inner wall of the arc-shaped splint fits the outer wall of the workpiece for stable position limiting. When the workpiece rotates, the arc-shaped splint is twisted, and the arc-shaped splint prompts the built-in intelligent module of the electric push rod to receive the external force twisting signal. At this time, the telescopic end of the electric push rod drives the arc-shaped splint to reset and no longer limit the workpiece. When the workpiece is adjusted, the arc-shaped splint is again fitted with its outer wall through the telescopic end of the electric push rod. At the same time, the telescopic end of the electric push rod drives the protective plate to slide synchronously along the top of the base, and the protective plate drives the mirror panel to move synchronously. When the mirror panel slides, it hits the top of the inclined rod. At this time, the hinge shaft of the inclined rod starts to rotate, prompting the inclined rod to start rotating with the hinge shaft as the axis, and the top of the inclined rod pushes the mirror panel to the inside of the protective plate and moves upward.

[0007] According to the above technical solution, the processing ring is located on the periphery of the toothed disk, and a circular groove is opened inside the processing ring. The bottom of the protective plate is slidably connected to the top of the base, the bottom of the inclined rod is hinged at the top edge of the processing ring, and the fixed plate is provided with an anti-crack device on the side close to the center of the base to avoid cracks caused by structural stress changes during the cutting and grinding of the workpiece gear ring.

[0008] According to the above technical solution, the anti-crack device includes an L-shaped push plate, a heating component, a connecting rod, a sliding plate and a plurality of activated carbon plates. The L-shaped push plate is fixedly installed on the outer wall of the protective plate near the center of the base, the bottom of the heating component is slidably installed on the top of the base, the outer wall of the heating component is fixedly connected to the inner wall of the L-shaped push plate, the connecting rod is rotatably installed at the edge of the inner wall of the fixed plate at one end away from the center of the base, a spiral groove is opened on the outer wall of the connecting rod, the sliding plate is fixedly installed on the outer wall of the L-shaped push plate near the outer wall of the protective plate, and the plurality of activated carbon plates are fixedly installed On the outer wall surface of the connecting rod, the telescopic end of the electric push rod drives the L-shaped push plate to move synchronously when it is extended and retracted, and the L-shaped push plate drives the heating component to slide synchronously along the top of the base. The heating component expands its own heat radiation range during the sliding process. At the same time, the heating component drives the sliding plate to slide synchronously along the outer wall of the spiral groove of the connecting rod. The connecting rod is in continuous contact with the inner wall of the non-self-locking spiral groove on its outer wall and the built-in block of the sliding plate, causing the connecting rod to generate a rotational force and start to rotate. When the connecting rod rotates, it drives the activated carbon plate to rotate. When the activated carbon plate rotates, it comes into contact with the smoke and pungent smell generated during the cutting and grinding of the workpiece gear ring.

[0009] According to the above technical solution, the bottom of the sliding plate is slidably connected to the top edge of the base, and the outer wall of the connecting rod spiral groove is in contact with the inner wall of the sliding plate. Several activated carbon plates are equidistantly distributed on the outer wall of the connecting rod, and an anti-detachment device is provided on the periphery of the L-shaped push plate to increase the friction between the workpiece and the arc-shaped clamping plate during processing.

[0010] According to the above technical scheme, the anti-crack device also includes a plurality of magnetic blocks and through plates, and the ends of the plurality of magnetic blocks away from the outer wall of the connecting rod are hinged inside the activated carbon plate, the outer wall of the through plate is horizontally penetrated by a spring and slidably installed inside the activated carbon plate, and a semicircular groove is opened on the outer wall of the through plate, and the arc surface of the magnetic block is located on the movement trajectory of the semicircular groove of the through plate, and the end of the through plate away from the center of the base is located on the movement trajectory of the sliding plate. When the activated carbon plate rotates, it drives the magnetic block to rotate, and the activated carbon plate drives the through plate to move synchronously, and when the sliding plate slides toward the center of the base, it resists the through plate and slides synchronously along the inside of the activated carbon plate, and the through plate contacts and resists the arc surface of the magnetic block through the semicircular groove to generate thrust, which prompts the hinge axis of the magnetic block to start rotating and the magnetic block to swing and deflect in an arc shape. When the sliding plate is reset, the through plate is reset by the spring force and pulls the magnetic block to reset.

[0011] According to the above technical solution, the anti-separation device includes a transmission belt, a reciprocating screw, a resistance plate and a moisture-proof plate. The transmission belt is installed on the outer wall of the connecting rod near the inner wall of the edge of the base. The reciprocating screw is rotatably installed on the inner wall of the fixed plate away from the center of the base. The resistance plate penetrates through and is slidably installed on the outer wall of the reciprocating screw. The moisture-proof plate is hinged on the inner wall of the fixed plate away from the outer wall of the protective plate. When the connecting rod rotates, the reciprocating screw is driven to rotate by the transmission belt. When the reciprocating screw rotates, it rotates through the reciprocating spiral groove on its outer wall The restriction of the block inside the contact plate and the continuous contact of the block with the inner wall of the reciprocating spiral groove make it possible for the contact plate to slide back and forth along the outer wall of the reciprocating screw toward the center of the base and reset when the reciprocating screw rotates. When the contact plate slides, it hits the inclined surface of the outer wall of the moisture-proof plate. After the moisture-proof plate is hit, its own hinge axis starts to rotate. At the same time, the moisture-proof plate starts to rotate in an arc shape with its own hinge axis as the center. When the moisture-proof plates on both sides rotate synchronously, the reset plate is squeezed and deformed. When the contact plate is reset, the moisture-proof plate is pushed to reset by the elastic force of the reset plate, and this process repeats reciprocatingly.

[0012] According to the above technical solution, the outer wall of the reciprocating screw is transmission connected to the inner wall of the transmission belt away from the edge of the base, the bottom of the resistance plate is slidably installed on the top of the base, the inclined surface of the outer wall of the moisture-proof plate is located on the movement trajectory of the resistance plate, and the moisture-proof plate has a built-in desiccant.

[0013] The bottom of the L-shaped plate is located on the moving track of the top of the L-shaped plate. When the reset plate is deformed and reset, it drives the L-shaped plate to move away from the center of the base and reset. When the L-shaped plate moves away from the center of the base, it contacts the curved surface of the bottom of the resonant plate. At this time, the cross plate limits the resonant plate to force the resonant plate to remain stationary. During the movement, the L-shaped plate causes the bottom of the resonant plate to deform and bend. When the L-shaped plate passes over the resonant plate, the resonant plate will swing back and forth and produce a slight vibration when it is reset by its own toughness, and the arc clamping plate will vibrate synchronously through the transmission of force.

[0014] The present invention provides an adjustable positioning device for machining a bearing gear ring. It has the following beneficial effects: (1) The present invention achieves the determination of the center position of the workpiece drop by cooperating with a transmission rod, a toothed disk, an elastic arc strip, a processing ring, a fixing plate, an electric push rod, an arc clamping plate, a protective plate, a mirror plate and an inclined rod. The elastic arc strip is deformed synchronously to ensure that the workpiece drop position is always at the center of the toothed disk to avoid irregularities during the processing of the gear ring. At the same time, the workpiece position adjustment process is simplified, which is different from the inconvenience caused by the need to disassemble the positioning components in the traditional adjustment, thereby reducing the labor intensity of the staff and improving the processing efficiency. Under the premise of not affecting the position adjustment of the workpiece, the workpiece is ensured to have good stability to prevent shaking during the processing process and cause processing accidents. At the same time, the mirror plate is used to facilitate the staff to observe the processing scene and processing progress of the workpiece in real time, thereby ensuring the processing accuracy and preventing the need to interrupt the processing flow to observe the workpiece.

[0015] (2) The present invention ensures that the processing area always has an adaptive temperature through the arrangement of an anti-crack device, through the coordination of an electric push rod, an L-shaped push plate, a heating assembly, a connecting rod, a sliding plate, an activated carbon plate, a magnetic block and a through plate, thereby preventing the increase of internal stress during the cold cutting of the workpiece gear ring, which may cause cracks to form at the cutting part of the workpiece, and preventing the overall quality of the workpiece from being reduced; at the same time, the activity range of the magnetic block during the revolution is expanded, and the magnetic block that orbits and swings back and forth absorbs the debris splashed during the processing of the workpiece gear ring onto its own surface, i.e., the inside of the activated carbon plate, thereby realizing the centralized collection of the splashed debris to avoid the debris splashing and injuring the vulnerable parts such as the eyes of the staff.

[0016] (3) The present invention adopts the setting of the anti-separation device, and cooperates with the connecting rod, the transmission belt, the reciprocating screw, the contact plate, the moisture-proof plate, the reset plate, the L-shaped plate, the horizontal plate and the resonance plate. The moisture-proof plate swings back and forth to absorb the mist generated by the cooling water source during the processing of the workpiece gear ring. The moisture-proof plate accelerates the mixing and drying speed of the desiccant and the mist inside the moisture-proof plate during the swinging process, thereby preventing the mirror plate from being blurred due to the attachment of water vapor, thereby affecting the observation clarity of the staff. At the same time, the arc clamping plate is prompted to rely on the vibration force to fill the fitting gap during the process of fitting itself and the outer wall of the workpiece, so that the arc clamping plate and the workpiece are more closely fitted, thereby preventing the workpiece from being separated during the orientation adjustment process and reducing the stability.

The mirror plate 14 is hinged with an inclined rod 15 on one side close to the center of the base 1. Through the above cooperation, the center orientation of the workpiece falling is determined, and the synchronous deformation of the elastic arc bar 8 ensures that the falling orientation of the workpiece is always in the center of the toothed disk 7 to avoid irregularities during the processing of the gear ring. At the same time, the workpiece orientation adjustment process is simplified, which is different from the inconvenience caused by the disassembly of the positioning components required for traditional adjustment, reduces the labor intensity of the staff and improves the processing efficiency; through the above cooperation, without affecting the orientation adjustment of the workpiece, it is ensured that the workpiece has good stability to prevent shaking during the processing and cause processing accidents. At the same time, relying on the mirror plate 14, it is convenient for the staff to observe the processing scene and processing progress of the workpiece in real time, ensuring the processing accuracy while also preventing the need to interrupt the processing flow to observe the workpiece.

[0021] The machining ring 9 is located on the periphery of the toothed disk 7, and a circular groove is provided inside the machining ring 9. The bottom of the protective plate 13 is slidably connected to the top of the base 1, and the bottom of the inclined rod 15 is hinged at the top edge of the machining ring 9. The fixing plate 10 is provided with an anti-crack device 4 on one side close to the center of the base 1 for preventing cracks from being generated due to structural stress changes during the cutting and grinding of the workpiece gear ring.

[0022] When in use, the center circular hole of the workpiece is placed downward from the top of the transmission rod 6 and with the transmission rod 6 as the center. When the center circular hole of the workpiece is placed downward to the periphery of the outer wall of the transmission rod 6, the inner wall of the workpiece contacts the inner wall of the elastic arc strip 8 and generates a resistance force. The elastic arc strip 8 is deformed by the resistance force, and the workpiece continues to descend. At this time, the extrusion pressure on the arc surface of the outer wall of the elastic arc strip 8 continues to increase until the workpiece falls to the top of the toothed disk 7, and the outside of the workpiece is located in the internal range of the machining ring 9.

When the workpiece rotates, the arc splint 12 is twisted, and the arc splint 12 prompts the built-in intelligent module of the electric push rod 11 to receive the external force twisting signal. At this time, the telescopic end of the electric push rod 11 drives the arc splint 12 to reset and no longer limit the workpiece. When the workpiece is adjusted, the arc splint 12 fits its outer wall again through the telescopic end of the electric push rod 11. At the same time, the telescopic end of the electric push rod 11 drives the protective plate 13 to slide synchronously along the top of the base 1, and the protective plate 13 drives the mirror plate 14 to move synchronously. When the mirror plate 14 slides, it contacts the top of the inclined rod 15. At this time, the hinge shaft of the inclined rod 15 starts to rotate, prompting the inclined rod 15 to start rotating with the hinge shaft as the axis.

A number of activated carbon plates 45 are equidistantly distributed on the outer wall of the connecting rod 43. An anti-detachment device 5 is provided on the periphery of the L-shaped push plate 41 to increase the friction between the workpiece and the arc-shaped clamping plate 12 during processing.

[0025] The anti-crack device 4 also includes a plurality of magnetic blocks 46 and a through plate 47. The ends of the plurality of magnetic blocks 46 away from the outer wall of the connecting rod 43 are hinged inside the activated carbon plate 45.

The heating component 42 expands its own heat radiation range during the sliding process, and at the same time, the heating component 42 drives the sliding plate 44 to slide synchronously along the outer wall of the spiral groove of the connecting rod 43. The connecting rod 43 is in continuous contact with the built-in block of the sliding plate 44 through the inner wall of the non-self-locking spiral groove on its outer wall, causing the connecting rod 43 to generate a rotating force and start to rotate. When the connecting rod 43 rotates, it drives the activated carbon plate 45 to rotate. When the activated carbon plate 45 rotates, it comes into contact with the smoke and pungent smell generated during the cutting and grinding of the workpiece gear ring.

When the sliding plate 44 slides toward the center of the base 1, it resists the through plate 47 and slides synchronously along the inside of the activated carbon plate 45. The through plate 47 contacts and resists the arc surface of the magnetic block 46 through the semicircular groove to generate thrust, which prompts the hinge axis of the magnetic block 46 to start rotating and the magnetic block 46 to swing and deviate in an arc shape. When the sliding plate 44 is reset, the through plate 47 is reset by the spring force and pulls the magnetic block 46 to reset. The above cooperation expands the range of movement of the magnetic block 46 during the revolution, and the magnetic block 46 that revolves and swings back and forth adsorbs the debris splashed during the processing of the workpiece gear ring on its own surface, that is, the inside of the activated carbon plate 45, so as to achieve centralized collection of the splashed debris and avoid the debris splashing the eyes and other vulnerable parts of the workers.

The outer wall of the L-shaped plate 56 movably passes through the interior of the fixed plate 10, and the transverse plate 57 is fixedly mounted on the outer wall of the fixed plate 10 on the side close to the moisture-proof plate 54. The tops of the plurality of resonance plates 58 are fixedly mounted on the bottom of the transverse plate 57, and the bottom of the resonance plate 58 is located on the movement trajectory of the top of the L-shaped plate 56. Through the above cooperation, the arc-shaped clamping plate 12 relies on the vibration force to make up for the fitting gap during the fitting process between itself and the outer wall of the workpiece, so that the arc-shaped clamping plate 12 and the workpiece fit more closely, preventing the workpiece from separating during the orientation adjustment process and reducing stability.

[0030] When in use, when the connecting rod 43 rotates, the transmission belt 51 drives the reciprocating screw rod 52 to rotate. When the reciprocating screw rod 52 rotates, the reciprocating spiral groove on its outer wall restricts the internal block of the contact plate 53, and the block constantly contacts the inner wall of the reciprocating spiral groove, so that when the reciprocating screw rod 52 rotates, the contact plate 53 can slide back and forth along the outer wall of the reciprocating screw rod 52 toward the center direction of the base 1 and reset. When the contact plate 53 slides, it contacts the inclined surface of the outer wall of the moisture-proof plate 54. After the moisture-proof plate 54 is contacted, its own hinge axis begins to rotate. At the same time, the moisture-proof plate 54 starts to rotate in an arc with its own hinge axis as the center. When the moisture-proof plates 54 on both sides rotate synchronously, the reset plate 55 is squeezed and deformed. When the contact plate 53 is reset, the moisture-proof plate 54 is pushed to reset by the elastic force of the reset plate 55, and this is repeated. Through the above cooperation, the moisture-proof plate 54 that relies on the reciprocating swinging swing absorbs the mist generated by the cooling water source during the processing of the workpiece gear ring, and accelerates the moisture-proof plate 54 during the swinging process. The mixed drying speed of the desiccant and the mist inside the mirror plate 14 is prevented from being blurred due to the attachment of water vapor, thereby affecting the staff's observation clarity; when the reset sheet 55 is deformed and reset, it drives the L-shaped plate 56 to move away from the center of the base 1 and reset. When the L-shaped plate 56 moves away from the center of the base 1, it contacts the bottom arc surface of the resonance plate 58. At this time, the cross plate 57 limits the resonance plate 58 to keep the resonance plate 58 still. During the movement, the L-shaped plate 56 causes the bottom of the resonance plate 58 to deform and bend. When the L-shaped plate 56 passes over the resonance plate 58, the resonance plate 58 will swing back and forth and produce a slight vibration when it is reset by its own toughness. The transmission of force causes the arc clamping plate 12 to vibrate synchronously. Through the above cooperation, the arc clamping plate 12 relies on the vibration force to make up the fitting gap during the process of fitting itself and the outer wall of the workpiece, so that the arc clamping plate 12 and the workpiece fit more closely, preventing the workpiece from detaching during the orientation adjustment process, thereby reducing stability.
