Technical Field
[0001] The invention relates to the technical field of bearing seat processing, and in particular to a quick locking device for a roller bearing seat. Background Art
[0002] Roller bearing seat is a large and extra-large bearing seat with special structure that can accept comprehensive loads. It has the characteristics of compact structure, sensitive rotation, easy installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the so-called bearing seat. The bearing seat plays an important role in the entire shaft system. It is generally located at both ends of the shaft. Its main function is to support and fix the bearing so that the shaft and its connecting parts have a certain positional relationship. According to the different requirements of bearings and bearing seats, the classification of bearing seats is not exactly the same. When using them, you must carefully check and select according to the design.
[0003] When processing the existing roller bearing seat, the inner ring processing, outer ring processing and bottom end face processing must be carried out in sequence. When processing the outer ring of the roller bearing seat, a special inner ring clamp is required to clamp and fix the bearing seat. When processing the inner ring of the bearing seat, a special outer ring clamp is required to clamp and fix the bearing seat. When processing the bottom end face of the roller bearing seat, a special end face clamp is required to clamp it. Therefore, according to different processing requirements, the corresponding bearing seat clamp needs to be replaced frequently, and the roller bearing seat needs to be disassembled and assembled many times, so the clamping efficiency is low. Summary of the Invention
[0004] In order to solve the problem that the corresponding bearing seat clamps need to be frequently replaced during the processing of the existing roller bearing seat, resulting in low clamping efficiency, the present invention provides a roller bearing seat quick locking device.
[0005] The present invention provides a quick locking device for a roller bearing seat adopts the following technical solution:
[0006] A quick locking device for a roller bearing seat includes a mounting frame, wherein the mounting frame includes a base, a vertical support frame fixed to the upper end of the base, and a horizontal support frame fixed to the right side of the upper end of the vertical support frame;
[0007] The posture adjustment mechanism includes a horizontal plate and a vertical plate, wherein the horizontal plate is arranged above the horizontal support frame, and the vertical plate is fixed to the upper end of the left side of the horizontal plate; an open groove is provided in the middle of the vertical plate, and a third avoidance groove extending in the left and right directions is provided in the middle of the horizontal plate and the horizontal support frame;
[0008] The sliding assembly includes two sets of connecting rods symmetrically fixed to the lower left side of the cross plate, the lower ends of the connecting rods are fixed with left and right horizontally arranged polished rods, and the outer sleeves of the polished rods are equipped with sliding bushings with second locking bolts;
[0009] The outer ring locking mechanism includes an outer ring base, which is connected to the sliding bushing on the corresponding side via a connecting block. The outer ring base is evenly distributed with four sets of outer ring claws that can be synchronously retracted or expanded in the radial direction to clamp or release the outer ring of the workpiece. The outer ring claw on the right side is located in the third avoidance groove;
[0010] The inner ring locking mechanism includes an inner ring base fixed above the outer ring base and coaxial with the outer ring base. Four groups of second plug rods that are synchronously retracted or expanded in the radial direction are evenly distributed on the upper end of the inner ring base. The upper end of the second plug rod is detachably connected to an inner ring clamp to clamp or release the inner ring of the workpiece.
[0011] By adopting the above technical solution, when the inner ring needs to be processed, the roller bearing seat workpiece is placed on the horizontal plate, and its outer ring is placed between the open grooves, and its bottom is placed between the vertical plate and the outer ring claw on the right side, and its bottom is placed close to the vertical plate toward the vertical plate; then the sleeve is slid to the left to drive the outer ring locking mechanism and the inner ring locking mechanism to move to the left, until the outer ring claw on the right touches the workpiece and initially presses the workpiece, and then the outer ring claw is synchronously retracted. Since the outer ring claw on the right is blocked from moving to the left by the vertical plate and the workpiece, the sliding sleeve can be driven to slide to the right by its reaction force, thereby causing the outer ring base to gradually move to the right, and at the same time The remaining three sets of outer ring jaws on it also gradually move closer to the workpiece until they touch and clamp the workpiece. Thereafter, the sliding bushing is locked by the second locking bolt, so that the outer ring locking mechanism and the inner ring locking mechanism are coaxially arranged with the outer ring of the workpiece when clamping the workpiece, so that the clamping axis is consistent with the workpiece to achieve axial positioning; during this period, when the workpiece deviates in the front and rear directions, such as backward, the outer ring jaws on the rear side can first contact the rear side of the workpiece and push it to the front side when retracting, and then until the outer ring jaws on the front side touch the front side of the workpiece. Since the outer ring jaws are evenly distributed and act synchronously, the workpiece can be automatically centered during the clamping process.
[0012] Then, since the inner ring locking mechanism is coaxially arranged with the outer ring of the workpiece during inner ring processing, it is only necessary to install the inner ring clamp on the second insertion rod on the inner side of the workpiece. The workpiece can be clamped from the inside by adjusting the expansion of the second insertion rod, and then the outer ring claws can be loosened to process the outer ring of the workpiece. At the same time, expanding the outer ring claws will not interfere with the subsequent processing of the bottom end face of the workpiece.
[0013] Therefore, compared with the existing processing method that requires frequent replacement of the corresponding bearing seat fixture and multiple disassembly and assembly of the roller bearing seat, the present invention can quickly realize the conversion of the inner and outer clamping methods of the workpiece, meet the processing requirements of the outer ring, inner ring and bottom end face of the workpiece, and greatly improve the clamping efficiency. At the same time, because it can realize automatic centering and axial positioning, the subsequent processing tool only needs to move on the travel route of the third avoidance groove, which provides convenient conditions for the positioning of the processing tool, thereby further improving the processing efficiency.
[0014] Optionally, the outer ring locking mechanism includes an outer ring base, in which a claw adjustment assembly for controlling the retraction or extension of the outer ring claw is provided, the claw adjustment assembly including an inner cylinder arranged coaxially with the outer ring base, a first rotating shaft provided in the inner cylinder for rotational engagement, a winding disk being fixed to the outside of the upper portion of the first rotating shaft, and a lower end of the first rotating shaft extending outside the inner cylinder and connected to the first rotating disk; a plurality of groups of first pin holes are correspondingly provided on the inner cylinder and the first rotating disk, and matching first latches are provided in the first pin holes; four groups of first sliding grooves extending radially are uniformly distributed on the outer ring base, first insertion rods matching therewith are provided in the first sliding grooves, and a first insertion hole detachably connected to the first insertion rod is provided at the lower end of the outer ring claw; a first slider connected thereto is provided in the inner cavity of the outer ring base below the first insertion rod, one end of the first slider being connected to the inner wall of the outer ring base via a first spring, and the other end of the first slider being connected to the winding disk via a traction rope, and a wire outlet groove matching the traction rope is correspondingly provided on the inner cylinder.
[0015] By adopting the above technical solution, the first rotating shaft can be driven to rotate by rotating the first turntable, thereby causing the winding drum to rotate and synchronously winding the four groups of traction ropes, so that the four groups of first sliders overcome the elastic force of the first spring and move synchronously inward. Due to the setting of the first slide groove and the first insertion rod, the outer ring claws can be synchronously retracted in the radial direction to approach the workpiece until the workpiece is clamped. After clamping, the first turntable is fixed by the first pin and the first socket to prevent it from reversing and loosening, thereby realizing rapid locking of the workpiece; conversely, the first pin is pulled out, and the first slider quickly resets under the elastic force of the first spring, thereby realizing rapid disassembly of the workpiece outer ring after clamping, further improving overall work efficiency.
[0016] Optionally, a rubber pad is provided on the inner side of the upper end of the outer ring clamping jaw, and auxiliary plates are symmetrically hinged on the left and right sides of the upper end of the outer ring clamping jaw on the front and rear sides. A torsion spring is provided at the hinge between the auxiliary plate and the outer ring clamping jaw, and the auxiliary plate is initially tilted toward one side of the workpiece.
[0017] By setting the rubber pad, on the one hand, the rubber pad can be used to cushion the workpiece during the clamping process to avoid scratching the outer ring of the workpiece. On the other hand, the friction coefficient between the workpiece and the workpiece is increased, so that the locking effect of the workpiece is more reliable. By setting the auxiliary plate and the torsion spring, since the auxiliary plate is initially tilted toward one side of the workpiece, the outer ring claws on the front and rear sides can contact the workpiece earlier than the outer ring claws on the left side during the clamping process. The reaction force of the torsion spring is used to perform the centering operation in advance before the workpiece is locked, avoiding the problem that the workpiece cannot move due to synchronous clamping of the outer ring claws and cannot be centered and positioned. At the same time, the clamping points of the outer ring claws on the front and rear sides are generally located between the upper arc section and the lower flat section of the outer ring of the workpiece, resulting in a smaller contact area when clamping, which makes it difficult to lock. Therefore, the auxiliary plate can perform surface extrusion on the lower flat section and linear extrusion on the upper arc section when clamping, which greatly increases the contact area and improves the locking effect.
[0018] Optionally, at least two groups of positioning holes are provided on the outer ring base.
[0019] By adopting the above technical solution and utilizing the positioning holes, after the outer ring clamping claws clamp the workpiece to complete the positioning of the outer ring locking mechanism, the machining tool can be quickly positioned through the external positioning guide rod and the positioning hole, thereby improving the overall machining efficiency.
[0020] Optionally, the inner ring locking mechanism includes an inner ring base, four groups of second sliding grooves extending radially are evenly distributed on the inner ring base; a second rotating shaft is coaxially arranged in the inner cavity of the inner ring base, a second rotating disk is fixedly provided outside the second rotating shaft, and four groups of arc grooves are centrally symmetrically provided on the second rotating disk, and the distance between each point of the arc groove and the center of the second rotating disk along the rotation direction of the arc groove gradually increases; a second slider is provided in the arc groove to slide with it, a movable block fixedly connected to the second slider is provided in the inner cavity of the inner ring base, and at least two groups of second insertion rods arranged radially are provided on the upper end of the movable block, the second insertion rods pass through the second sliding grooves and are detachably connected to the inner ring clamping block through the second insertion hole; an outwardly extending adjustment handle is fixedly provided on one side of the second rotating disk, and a notch matching the adjustment handle is correspondingly provided on the side surface of the inner ring base; a second pin hole is provided on the outer end of the adjusting handle, and a plurality of second pin holes are correspondingly provided on the upper end of the outer ring base, and second pins are correspondingly provided in the second pin holes.
[0021] By adopting the above technical solution, the adjusting handle is turned to drive the second turntable to rotate. Due to the setting of the arc groove and the second sliding groove, the second sliding block slides outward in the arc groove guide, and then drives the second insertion rod and the inner ring clamp to expand outward along the second sliding groove through the movable block until the inner ring of the workpiece is clamped, and then the adjusting handle and the outer ring base are connected through the second pin and the second pin hole to achieve rapid locking of the inner ring clamp; in addition, the setting of the arc groove and the second turntable makes the adjustment mechanism of the inner ring clamp compact, and the adjustment handle can be adjusted within a smaller arc range to achieve a larger radial displacement of the inner ring clamp, avoiding interference with the outer ring claws and causing difficulty in adjusting the inner ring clamp; at least two groups of second insertion rods arranged radially are provided at the upper end of the movable block. Such a setting can fix the orientation of the inner ring clamp, and thus always clamp it radially, thereby ensuring the clamping effect.
[0022] Optionally, a recessed groove is provided on the outer side of the inner ring clamp away from the side of the vertical plate, and multiple groups of second springs are arranged at intervals in the recessed groove. The outer ends of the second springs extend outside the recessed groove and are connected to the pre-loaded blocks. The pre-loaded blocks can overcome the elastic force of the second springs and be received in the recessed groove when under pressure.
[0023] By adopting the above technical solution and utilizing the arrangement of the sink groove, the second spring and the pre-pressing block, the inner ring clamp on the left can contact the inner ring of the workpiece in advance through the pre-pressing block when it is expanded, and then as it gradually expands, the pre-pressing block overcomes the second spring and retracts into the sink groove, thereby utilizing the reaction force of the second spring to always apply a leftward force to the workpiece after the inner ring clamp clamps the inner ring of the workpiece, and then cooperate with the vertical plate to assist in clamping the workpiece while making the bottom end face of the workpiece flush with the vertical plate, thereby avoiding slight twisting of the bottom end face causing tilt and affecting the processing quality.
[0024] Optionally, the middle part of the horizontal plate is hinged to the left side of the horizontal support frame through a hinge shaft, and the four corners of the horizontal plate are provided with a first locking hole with a first locking bolt, and the mounting frame is correspondingly provided with a first locking hole matching it; the vertical support frame is provided with a first avoidance groove for avoiding the sliding component, the outer ring locking mechanism and the inner ring locking mechanism.
[0025] By adopting the above technical solution, using the setting of the hinge shaft, the first avoidance groove and the first locking bolt, the cross plate can be flipped to be in a horizontal or vertical state, and locked and fixed to the mounting frame by the first locking bolt, so that the bottom of the workpiece can be flipped to an upward arrangement, making it convenient for the bottom end face tool to be processed from above.
[0026] Optionally, two groups of second avoidance grooves are symmetrically arranged on the horizontal plate at the front and rear sides of the third avoidance groove, and the vertical support frame is correspondingly provided with a stopper matching the second avoidance groove.
[0027] Since the width of the bottom of the workpiece is actually greater than the thickness of its outer ring during actual processing, it is easy to cause it to tilt from the bottom to the outer ring side when placed on the horizontal plate, resulting in the workpiece still being in a tilted state after the outer ring claws clamp the workpiece, which can easily lead to large processing deviations in the inner ring of the workpiece and even defective products. Therefore, the second avoidance groove is used to accommodate the bottom of the workpiece, so that the lower end of the outer ring of the workpiece is fit with the horizontal plate, so that the workpiece is always in a horizontal state, thereby ensuring the processing quality; through the setting of the stop block, the bottom of the workpiece can be squeezed out by the stop block when the workpiece is flipped to the bottom side facing up, and then clamped by the inner ring clamp, avoiding the problem that the bottom surface of the workpiece is located in the second avoidance groove and cannot be processed.
[0028] In summary, the present invention includes at least one of the following beneficial technical effects:
[0029] 1. Compared with the existing processing method that requires frequent replacement of the corresponding bearing seat clamps and multiple disassembly and assembly of the roller bearing seat, the present invention can quickly realize the conversion of the inner and outer clamping methods of the workpiece, meet the processing requirements of the outer ring, inner ring and bottom end face of the workpiece, and greatly improve the clamping efficiency. At the same time, because it can realize automatic centering and axial positioning, the subsequent processing tool only needs to move on the travel route of the third avoidance groove, which provides convenient conditions for the positioning of the processing tool, thereby further improving the processing efficiency.
[0030] 2. Through the setting of the auxiliary plate and the torsion spring, since the auxiliary plate is initially inclined toward one side of the workpiece, the outer ring jaws on the front and rear sides can contact the workpiece earlier than the outer ring jaws on the left side during the clamping process, thereby utilizing the reaction force of the torsion spring to perform the centering operation in advance before the workpiece is locked, thereby avoiding the problem that the workpiece cannot move and cannot be centered and positioned due to the synchronous clamping of the outer ring jaws. At the same time, the clamping points of the outer ring jaws on the front and rear sides are generally located between the upper arc section and the lower flat section of the outer ring of the workpiece, resulting in a smaller contact area when clamping, making it difficult to lock. Therefore, the auxiliary plate can be used to perform surface extrusion on the lower flat section and linear extrusion on the upper arc section when clamping, which greatly increases the contact area and improves the locking effect.
[0031] 3. By utilizing the arrangement of the sink groove, the second spring and the pre-pressing block, the inner ring clamp on the left can contact the inner ring of the workpiece in advance through the pre-pressing block when it is expanded, and then as it gradually expands, the pre-pressing block overcomes the second spring and retracts into the sink groove, thereby utilizing the reaction force of the second spring to always apply a leftward force to the workpiece after the inner ring clamp clamps the inner ring of the workpiece, and then cooperate with the vertical plate to assist in clamping the workpiece while making the bottom end face of the workpiece flush with the vertical plate, thereby avoiding slight twisting of the bottom end face causing tilt and affecting the processing quality.

DETAILED DESCRIPTION
[0043] The following is combined with Figures 1-9 The present invention is described in further detail.
[0044] An embodiment of the present invention discloses a quick locking device for a roller bearing seat.
[0045] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0046] Reference Figures 1-9 A quick locking device for a roller bearing seat includes a mounting frame 1, wherein the mounting frame 1 includes a base 11, a vertical support frame 12 fixed to the upper end of the base 11, and a horizontal support frame 13 fixed to the right side of the upper end of the vertical support frame 12;
[0047] The posture adjustment mechanism 2 includes a horizontal plate 21 and a vertical plate 22. The horizontal plate 21 is arranged above the horizontal support frame 13, and the vertical plate 22 is fixed to the upper left end of the horizontal plate 21. An open slot 23 is provided in the middle of the vertical plate 22. A third avoidance slot 26 extending in the left-right direction is provided in the middle of the horizontal plate 21 and the horizontal support frame 13.
[0048] The sliding assembly 3 includes two sets of connecting rods 31 symmetrically fixed to the lower left side of the cross plate 21. The lower ends of the connecting rods 31 are fixed with left and right horizontally arranged polished rods 32. The polished rods 32 are sheathed with sliding bushings 33 with second locking bolts 34.
[0049] The outer ring locking mechanism 4 includes an outer ring base 41, which is connected to the sliding bushing 33 on the corresponding side via a connecting block 35. Four groups of outer ring claws 43 are evenly distributed on the outer ring base 41, which can be synchronously retracted or expanded in the radial direction to clamp or release the outer ring of the workpiece 6. The outer ring claw 43 on the right side is located in the third avoidance groove 26;
[0050] The inner ring locking mechanism 5 includes an inner ring base 51 fixed above the outer ring base 41 and coaxial with the outer ring base 41. Four groups of second insertion rods 57 that are synchronously retracted or expanded in the radial direction are evenly distributed on the upper end of the inner ring base 51. The upper end of the second insertion rod 57 is detachably connected to an inner ring clamp 55 to clamp or release the inner ring of the workpiece 6.
[0051] By adopting the above technical solution, when the inner ring needs to be processed, the roller bearing seat workpiece 6 is placed on the horizontal plate 21, and its outer ring is placed between the open grooves 23. At the same time, its bottom is placed between the vertical plate 22 and the outer ring claw 43 on the right side, and its bottom is placed close to the vertical plate 22 toward the side of the vertical plate 22; then the left sliding bushing 33 drives the outer ring locking mechanism 4 and the inner ring locking mechanism 5 to move to the left until the outer ring claw 43 on the right touches the workpiece 6 and initially presses the workpiece 6, and then the outer ring claw 43 is synchronously retracted. Since the outer ring claw 43 on the right is blocked from moving to the left by the vertical plate 22 and the workpiece 6, it can drive the sliding bushing 33 to slide to the right through its reaction force, thereby causing the outer ring base 41 to gradually move to the right. When the workpiece 6 is clamped, the outer ring locking mechanism 4 and the inner ring locking mechanism 5 are coaxially arranged with the outer ring of the workpiece 6, so that the clamping axis thereof is consistent with the workpiece 6 to achieve axial positioning; during this period, when the workpiece 6 deviates in the front and rear directions, such as deviating backward, the outer ring clamping mechanism 43 on the rear side can first contact the rear side of the workpiece 6 and push it forward when retracting, and then until the outer ring clamping mechanism 43 on the front side touches the front side of the workpiece 6. Since the outer ring clamping mechanism 43 is evenly distributed and moves synchronously, the workpiece 6 can be automatically centered during the clamping process.
[0052] Then, since the inner ring locking mechanism 5 is already coaxially arranged with the outer ring of the workpiece 6 during the inner ring processing, it is only necessary to install the inner ring clamp 55 on the second insertion rod 57 on the inner side of the workpiece 6. The workpiece 6 can be clamped from the inside by adjusting the expansion of the second insertion rod 57, and then the outer ring claw 43 can be loosened to process the outer ring of the workpiece 6. At the same time, expanding the outer ring claw 43 will not interfere with the subsequent processing of the bottom end face of the workpiece 6.
[0053] Therefore, compared with the existing processing method that requires frequent replacement of the corresponding bearing seat fixture and multiple disassembly and assembly of the roller bearing seat, the present invention can quickly realize the conversion of the inner and outer clamping methods of the workpiece 6, meet the processing requirements of the outer ring, inner ring and bottom end face of the workpiece 6, and greatly improve the clamping efficiency. At the same time, because it can realize automatic centering and axial positioning, the subsequent processing tool only needs to move on the travel route of the third avoidance groove 26, which provides convenient conditions for the positioning of the processing tool, thereby further improving the processing efficiency.
[0054] Specifically, the outer ring locking mechanism 4 includes an outer ring base 41, and a claw adjustment component 47 for controlling the retraction or expansion of the outer ring claw 43 is provided in the outer ring base 41. The claw adjustment component 47 includes an inner cylinder 475 arranged coaxially with the outer ring base 41, and a first rotating shaft 476 for rotation is provided in the inner cylinder 475. A winding disk 477 is fixed to the outer part of the upper part of the first rotating shaft 476, and the lower end of the first rotating shaft 476 extends to the outside of the inner cylinder 475 and is connected to the first rotating disk 479; a plurality of groups of first pin holes (not marked) are correspondingly provided on the inner cylinder 475 and the first rotating disk 479, and a matching first latch is provided in the first pin hole (not shown). 47 is provided on the outer ring base 41, and a first plug rod 474 is provided in the first slide groove 42 to match it. The lower end of the outer ring claw 43 is provided with a first jack which is detachably connected to the first plug rod 474. A first slider 472 is provided in the inner cavity of the outer ring base 41 below the first plug rod 474, and one end of the first slider 472 is connected to the inner wall of the outer ring base 41 through a first spring 471, and the other end of the first slider 472 is connected to the winding drum 477 through a traction rope 473. The inner cylinder 475 is provided with a corresponding outlet groove 478 which matches the traction rope 473.
[0055] By adopting the above technical solution, the first rotating shaft 476 can be driven to rotate by rotating the first turntable 479, thereby causing the winding disk 477 to rotate and synchronously winding the four groups of traction ropes 473, so that the four groups of first sliders 472 overcome the elastic force of the first spring 471 and move synchronously inward. Due to the setting of the first slide groove 42 and the first insertion rod 474, the outer ring clamping claw 43 can be synchronously retracted in the radial direction to approach the workpiece 6 until the workpiece 6 is clamped. After clamping, the first turntable 479 is fixed by the first pin and the first socket to prevent it from reversing and loosening, thereby realizing rapid locking of the workpiece 6; conversely, when the first pin is pulled out, the first slider 472 is quickly reset under the elastic force of the first spring 471, thereby realizing rapid disassembly after the outer ring of the workpiece 6 is clamped, further improving the overall work efficiency.
[0056] Specifically, rubber pads 44 are provided on the inner sides of the upper ends of the outer ring claws 43, and auxiliary plates 45 are symmetrically hinged on the left and right sides of the upper ends of the outer ring claws 43 on the front and rear sides. A torsion spring is provided at the hinge between the auxiliary plate 45 and the outer ring claws 43, and the auxiliary plate 45 is initially tilted toward the side of the workpiece 6.
[0057] The provision of the rubber pad 44, on the one hand, prevents scratches on the outer ring of the workpiece 6 by utilizing its cushioning effect during the clamping process, and on the other hand, increases the friction coefficient between the workpiece 6 and the workpiece 6, thereby making the locking effect of the workpiece 6 more reliable. The provision of the auxiliary plate 45 and the torsion spring, because the auxiliary plate 45 is initially tilted toward the side of the workpiece 6, allows the front and rear outer ring jaws 43 to contact the workpiece 6 earlier than the left outer ring jaw 43 during the clamping process. The reaction force of the torsion spring is then utilized to perform a centering operation before the workpiece 6 is locked, thereby avoiding the problem of the outer ring jaws 43 being clamped synchronously, resulting in the workpiece 6 being unable to move and unable to complete centering and positioning. At the same time, the clamping points of the front and rear outer ring jaws 43 are generally located between the upper arc segment and the lower flat segment of the outer ring of the workpiece 6, resulting in a small contact area during clamping, making it difficult to lock. Therefore, the auxiliary plate 45 can perform surface compression on the lower flat segment and linear compression on the upper arc segment during clamping, greatly increasing the contact area and improving the locking effect.
[0058] Specifically, at least two groups of positioning holes 46 are provided on the outer ring base 41 .
[0059] By adopting the above technical solution and utilizing the positioning hole 46 , after the outer ring clamping claw 43 clamps the workpiece 6 to complete the positioning of the outer ring locking mechanism 4 , the machining tool can be quickly positioned through the external positioning guide rod and the positioning hole 46 , thereby improving the overall machining efficiency.
[0060] Specifically, the inner ring locking mechanism 5 includes an inner ring base 51, on which four groups of second sliding grooves 56 extending in the radial direction are evenly distributed; a second rotating shaft 58 is coaxially arranged in the inner cavity of the inner ring base 51, and a second rotating disk 59 is fixedly provided on the outside of the second rotating shaft 58, and four groups of arc grooves 591 are centrally symmetrically provided on the second rotating disk 59, and the distance between each point of the arc groove 591 and the center of the second rotating disk 59 along the rotation direction gradually increases; a second sliding block 592 is provided in the arc groove 591 to slide with it, and a second sliding block 592 is provided in the inner cavity of the inner ring base 51 to slide with the second sliding block The movable block 593 is fixedly connected to the block 592, and at least two groups of radially arranged second plug rods 57 are provided at the upper end of the movable block 593. The second plug rods 57 pass through the second slide groove 56 and are detachably connected to the inner ring clamping block 55 through the second plug hole 551; an outwardly extending adjusting handle 53 is fixedly provided on one side of the second turntable 59, and a notch 52 matching the adjusting handle 53 is correspondingly provided on the side surface of the inner ring base 51; a second pin hole 54 is provided at the outer end of the adjusting handle 53, and a plurality of groups of second pin holes 54 are correspondingly provided at the upper end of the outer ring base 41, and a second pin is correspondingly provided in the second pin hole 54.
[0061] By adopting the above technical solution, the adjusting handle 53 is turned to drive the second rotating disk 59 to rotate. Due to the arrangement of the arc groove 591 and the second sliding groove 56, the second sliding block 592 slides outward in the arc groove 591, and then drives the second insertion rod 57 and the inner ring clamping block 55 to expand outward along the second sliding groove 56 through the movable block 593 until the inner ring of the workpiece 6 is clamped. Then, the adjusting handle 53 and the outer ring base 41 are connected through the second latch and the second pin hole 54 to achieve rapid locking of the inner ring clamping block 55. In addition, the arc groove 591 and the second The setting of the turntable 59 makes the adjustment mechanism of the inner ring clamp 55 compact, and can adjust the adjustment handle 53 within a smaller arc range to achieve a larger radial displacement of the inner ring clamp 55, avoiding interference with the outer outer ring claw 43 and causing difficulty in adjusting the inner ring clamp 55, while also improving the speed of clamping the inner ring of the workpiece 6; at least two groups of radially arranged second insertion rods 57 are provided at the upper end of the movable block 593. Such a setting can fix the orientation of the inner ring clamp 55, and thus always clamp it radially, thereby ensuring the clamping effect.
[0062] Specifically, a recessed groove 552 is provided on the outer side of the inner ring clamp 55 away from the side of the vertical plate 22, and multiple groups of second springs 554 are arranged at intervals in the recessed groove 552. The outer ends of the second springs 554 extend to the outside of the recessed groove 552 and are connected to the pre-loaded blocks 553. The pre-loaded blocks 553 can overcome the elastic force of the second springs 554 and be received in the recessed groove 552 when under pressure.
[0063] By adopting the above technical solution, utilizing the arrangement of the recessed groove 552, the second spring 554 and the pre-pressing block 553, the inner ring clamp 55 on the left can contact the inner ring of the workpiece 6 in advance through the pre-pressing block 553 when it is unfolded, and then as it gradually unfolds, the pre-pressing block 553 overcomes the second spring 554 and retracts into the recessed groove 552, thereby utilizing the reaction force of the second spring 554 to always apply a leftward force to the workpiece 6 after the inner ring clamp 55 clamps the inner ring of the workpiece 6, and then cooperates with the vertical plate 22 to assist in clamping the workpiece 6 while making the bottom end face of the workpiece 6 flush with the vertical plate 22, thereby avoiding slight twisting of the bottom end face causing tilt and affecting the processing quality.
[0064] Specifically, the middle part of the horizontal plate 21 is hinged to the left side of the horizontal support frame 13 through a hinge shaft 25, and the four corners of the horizontal plate 21 are provided with a first locking hole 27 with a first locking bolt 28, and the mounting frame 1 is correspondingly provided with a first locking hole 27 matching it; the vertical support frame 12 is provided with a first avoidance groove 14 for avoiding the sliding component 3, the outer ring locking mechanism 4 and the inner ring locking mechanism 5.
[0065] By adopting the above technical solution, using the arrangement of the hinge shaft 25, the first avoidance groove 14 and the first locking bolt 28, the cross plate 21 can be flipped to be in a horizontal or vertical state, and locked and fixed to the mounting frame 1 by the first locking bolt 28, so that the bottom of the workpiece 6 can be flipped to an upward arrangement, making it convenient for the bottom end face tool to be processed from above.
[0066] Specifically, two groups of second avoidance grooves 24 are symmetrically provided on the horizontal plate 21 at the front and rear sides of the third avoidance groove 26 , and the vertical support frame 12 is correspondingly provided with a stopper 15 matching the second avoidance grooves 24 .
[0067] Since the width of the bottom of the workpiece 6 is actually greater than the thickness of its outer ring during actual processing, it is easy to cause it to tilt from the bottom to the outer ring side when placed on the cross plate 21, resulting in the workpiece 6 still being in a tilted state after the outer ring claw 43 clamps the workpiece 6, which can easily lead to large processing deviations in the inner ring of the workpiece 6 and even defective products. Therefore, the second avoidance groove 24 is used to accommodate the bottom of the workpiece 6, so that the lower end of the outer ring of the workpiece 6 is in contact with the cross plate 21, so that the workpiece 6 is always in a horizontal state, thereby ensuring the processing quality; through the setting of the stop block 15, the bottom of the workpiece 6 can be squeezed out by the stop block 15 when the workpiece 6 is flipped to the bottom side facing up, and then clamped by the inner ring clamp 55, avoiding the problem that the bottom surface of the workpiece 6 is located in the second avoidance groove 24 and cannot be processed.
[0068] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
