Description

Technical Field

[0001] The present invention relates to the technical field of bearing housing processing, and particularly relates to a quick locking device for a roll bearing housing. Background Art

[0002] A roll bearing housing is a large and extra-large bearing housing that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, convenient installation and maintenance, etc. 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 housing. The bearing housing plays an important role in the entire shafting 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 components have a certain positional relationship. According to the different requirements of the bearing and the bearing housing, the classification of the bearing housing is not completely the same. When in use, it should be carefully checked and selected according to the design.

[0003] When processing the existing roll bearing housing, inner ring processing, outer ring processing and bottom end face processing need to be carried out in sequence. When processing the outer ring of the roll bearing housing, a special inner ring fixture is required to clamp and fix the bearing housing. When processing the inner ring of the bearing housing, a special outer ring fixture is required to clamp and fix the bearing housing. When processing the bottom end face of the roll bearing housing, a special end face fixture is required for clamping. Therefore, according to different processing requirements, the corresponding bearing housing fixtures need to be frequently replaced, and the roll bearing housing needs to be disassembled and assembled multiple times. Therefore, the clamping efficiency is low. Summary of the Invention

[0004] In order to solve the problem that the existing roll bearing housing needs to frequently replace the corresponding bearing housing fixtures during processing, resulting in low clamping efficiency, the present invention provides a quick locking device for a roll bearing housing.

[0005] The quick locking device for a roll bearing housing provided by the present invention adopts the following technical solutions: A quick locking device for a roll bearing housing includes a mounting frame, and 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 upper right side of the vertical support frame; An attitude adjustment mechanism includes a horizontal plate and a vertical plate. The horizontal plate is arranged above the horizontal support frame, and the vertical plate is fixed to the upper left end of the horizontal plate. An opening groove is provided in the middle of the vertical plate, and a third avoidance groove extending in the left-right direction is provided in the middle of the horizontal plate and the horizontal support frame; A sliding assembly includes two groups of connecting rods symmetrically fixed to the lower left side of the horizontal plate. The lower ends of the connecting rods are fixedly provided with a smooth rod arranged horizontally left and right. A sliding bushing with a second locking bolt is sleeved outside the smooth rod; The outer ring locking mechanism includes an outer ring base, which is connected to the corresponding sliding bushing by a connecting block. Four groups of outer ring claws that synchronously close or expand radially are evenly distributed on the outer ring base to clamp or release the outer ring of the workpiece. The outer ring claws on the right side are located in the third avoidance groove; 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 insertion rods that synchronously close or expand radially are evenly distributed at the upper end of the inner ring base. The upper end of the second insertion rod is detachably connected with an inner ring clamping block to clamp or release the inner ring of the workpiece.

[0006] By adopting the above technical solutions, when inner ring machining is required, the roll bearing seat workpiece is placed on the cross plate, its outer ring is placed between the opening grooves, and at the same time its bottom is placed between the vertical plate and the outer ring claws on the right side, and its bottom is placed close to the vertical plate with the bottom facing the vertical plate side; then slide the bushing 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 claws on the right side touch the workpiece and initially press the workpiece, and then synchronously close the outer ring claws. Since the outer ring claws on the right side are blocked by the vertical plate and the workpiece from moving to the left, the reaction force can drive the bushing to slide to the right, thereby causing the outer ring base to gradually move to the right, and the other three groups of outer ring claws on it also gradually approach the workpiece until they touch the workpiece and clamp the workpiece. After that, lock the bushing with the second locking bolt, and the outer ring locking mechanism and the inner ring locking mechanism can be coaxially arranged with the outer ring of the workpiece when clamping the workpiece, so that its clamping axis is consistent with the workpiece, realizing axial positioning; during this period, when the workpiece deviates in the front-back direction, such as moving backward, the outer ring claws at the rear can first contact the rear side of the workpiece and push it forward when closing, and then until the outer ring claws at the front touch the front side of the workpiece. Since the outer ring claws are evenly distributed and act synchronously, automatic centering of the workpiece can be realized during the clamping process.

[0007] Then, since the inner ring locking mechanism has been coaxially arranged with the outer ring of the workpiece during inner ring machining, at this time, only the inner ring clamping block needs to be installed on the second insertion rod on the inner side of the workpiece, and the workpiece can be clamped from the inner side by adjusting the expansion of the second insertion rod. Then loosen the outer ring claws to machine the outer ring of the workpiece, and the subsequent machining of the bottom end face of the workpiece will not be interfered with after the outer ring claws are expanded.

[0008] Therefore, compared with the existing machining method that requires frequent replacement of the corresponding bearing seat fixtures and multiple disassembly and assembly of the roll bearing seat, the present invention can quickly realize the conversion of the inner and outer clamping methods of the workpiece, meet the machining requirements of the outer ring, inner ring and bottom end face of the workpiece, greatly improve the clamping efficiency, and at the same time, because it can realize automatic centering and axial positioning, the subsequent machining tool only needs to move on the traveling route of the third avoidance groove, which provides convenient conditions for the positioning of the machining tool, and further improves the machining efficiency.

[0009] Optionally, the outer ring locking mechanism includes an outer ring base, a claw adjustment assembly for controlling the retraction or expansion of the outer ring claw is arranged in the outer ring base, the claw adjustment assembly includes an inner cylinder coaxially arranged with the outer ring base, a first rotating shaft for rotational cooperation is arranged in the inner cylinder, a winding disk is fixed on the upper part of the first rotating shaft, and the lower end of the first rotating shaft extends to the outside of the inner cylinder and is connected with the first rotating disk; a plurality of groups of first pin holes are correspondingly arranged on the inner cylinder and the first rotating disk, and a matching first plug is arranged in the first pin hole; four groups of first sliding grooves extending radially are evenly distributed on the outer ring base, a first plug rod matching therewith is arranged in the first sliding groove, and a first plug hole detachably connected to the first plug rod is arranged at the lower end of the outer ring claw; a first slider connected thereto is arranged in the inner cavity of the outer ring base below the first plug rod, one end of the first slider is connected to the inner wall of the outer ring base through a first spring, and the other end of the first slider is connected to the winding disk through a traction rope, and a wire outlet groove matching the traction rope is correspondingly arranged on the inner cylinder.

[0010] By adopting the above technical scheme, the first rotating shaft can be driven to rotate by rotating the first rotating disk, thereby causing the winding disk to rotate and synchronously winding up the four groups of traction ropes, so that the four groups of first sliding blocks overcome the elastic force of the first spring and move synchronously inward. Due to the setting of the first sliding groove and the first plug 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 rotating disk is fixed by the first pin and the first plug hole to prevent it from reversing and loosening, thereby realizing rapid locking of the workpiece; conversely, the first pin is pulled out, and the first sliding block is quickly reset under the elastic force of the first spring, thereby realizing rapid disassembly of the outer ring of the workpiece after clamping, thereby further improving the overall work efficiency.

[0011] 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 inclined toward one side of the workpiece.

[0012] Through the setting of the rubber pad, on the one hand, the buffer during the clamping process of the rubber pad is utilized to avoid scratching the outer ring of the workpiece. On the other hand, the friction coefficient between the rubber pad and the workpiece is increased, making the locking effect of the workpiece more reliable. Through the setting of the auxiliary plate and the torsion spring, since the auxiliary plate is inclined towards the workpiece side initially, during the clamping process, the outer ring claws on the front and rear sides can contact the workpiece earlier than the outer ring claws on the left side. Thus, by using the reaction force of the torsion spring, the centering operation can be carried out in advance before the workpiece is locked, avoiding the problem that the workpiece cannot move and the centering and positioning cannot be completed due to the synchronous clamping of the outer ring claws. At the same time, the clamping positions of the outer ring claws on the front and rear sides are generally between the upper arc section and the lower plane section of the outer ring of the workpiece, resulting in a relatively small contact area during clamping and making it difficult to lock. Therefore, through the auxiliary plate, surface extrusion can be carried out on the lower plane section and linear extrusion can be carried out on the upper arc section during clamping, greatly increasing the contact area and improving the locking effect.

[0013] Optionally, at least two groups of positioning holes are provided on the outer ring base.

[0014] By adopting the above technical solution, by using the positioning holes, after the outer ring claws clamp the workpiece to complete the positioning of the outer ring locking mechanism, the processing tool can be quickly positioned through the external positioning guide rod and the positioning holes, thereby improving the overall processing efficiency.

[0015] Optionally, the inner ring locking mechanism includes an inner ring base, on which four groups of second chutes extending radially are evenly distributed; a second rotating shaft is coaxially arranged in the inner cavity of the inner ring base, a second turntable is fixedly arranged outside the second rotating shaft, four groups of arc-shaped grooves are symmetrically arranged at the center of the second turntable, and the distance between each point on the arc-shaped groove along its rotation direction and the center of the second turntable gradually increases; a second slider slidably matched with the arc-shaped groove is arranged in the arc-shaped groove, a movable block fixedly connected with the second slider is arranged in the inner cavity of the inner ring base, at least two groups of second insertion rods arranged radially are arranged at the upper end of the movable block, the second insertion rods pass through the second chutes and are detachably connected with the inner ring clamping blocks through second insertion holes; an adjusting handle extending outwards is fixedly arranged on one side of the second turntable, a notch matched with the adjusting handle is correspondingly arranged on the side surface of the inner ring base; a second pin hole is arranged at the outer end of the adjusting handle, and multiple groups of second pin holes are correspondingly arranged at the upper end of the outer ring base, and second pins are correspondingly arranged in the second pin holes.

[0016] By adopting the above technical solution, the second turntable is driven to rotate by toggling the adjustment handle. Due to the arrangement of the arc groove and the second chute, the second slider slides outwards under the guidance of the arc groove, and then drives the second insertion rod and the inner ring clamping block to expand outwards along the second chute through the movable block until the inner ring of the workpiece is clamped. Then, the adjustment handle and the outer ring base are connected through the second pin and the second pin hole to achieve the quick locking of the inner ring clamping block; in addition, by using the arrangement of the arc groove and the second turntable, the adjustment mechanism of the inner ring clamping block has a compact structure, and the adjustment handle can be adjusted within a small arc range to achieve a large radial displacement of the inner ring clamping block, avoiding the problem of difficult adjustment of the inner ring clamping block due to interference with the outer ring claws on the outside; at least two groups of second insertion rods arranged radially are provided at the upper end of the movable block. With this arrangement, the orientation of the inner ring clamping block can be fixed, and it can always clamp along the radial direction, thus ensuring the clamping effect.

[0017] Optionally, a sink is provided on the outer side of the inner ring clamping block far from the vertical plate. A plurality of groups of second springs are arranged at intervals in the sink. The outer ends of the second springs extend outside the sink and are all connected to the preloading block. The preloading block can be received into the sink against the elastic force of the second spring when being pressed.

[0018] By adopting the above technical solution, by using the arrangement of the sink, the second spring and the preloading block, the inner ring clamping block on the left side can contact the inner ring of the workpiece in advance through the preloading block when expanding, and then the preloading block retracts into the sink by overcoming the second spring as it gradually expands. Thus, the reaction force of the second spring is used to always apply a leftward force to the workpiece after the inner ring clamping block clamps the inner ring of the workpiece, and then cooperate with the vertical plate to assist in clamping the workpiece and making the bottom end face of the workpiece flush with the vertical plate, thereby avoiding the problem that the bottom end face twists slightly and tilts, which affects the processing quality.

[0019] Optionally, the middle of the cross plate is hinged to the left side of the horizontal support frame through a hinge shaft. First locking holes with first locking bolts are provided at the four corners of the cross plate, and the mounting frame is correspondingly provided with matching first locking holes; a first avoidance groove for avoiding the sliding assembly, the outer ring locking mechanism and the inner ring locking mechanism is provided on the vertical support frame.

[0020] By adopting the above technical solution, by using the arrangement 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 through the first locking bolt, so that the bottom of the workpiece can be flipped upwards, facilitating the processing of the bottom end face tool from above.

[0021] Optionally, two groups of second avoidance grooves are symmetrically arranged on the cross plate on both sides before and after the third avoidance groove, and the vertical support frame is correspondingly provided with blocks matching the second avoidance grooves.

[0022] Since the width of the bottom of the workpiece is actually greater than the thickness of its outer ring during actual processing, it is likely to cause the workpiece to tilt from the bottom to the outer ring side when placed on the cross plate. As a result, the workpiece remains tilted after the outer ring jaws clamp the workpiece, which can easily lead to large machining deviations in the inner ring of the workpiece or 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 fits against the cross plate, keeping the workpiece always in a horizontal state, and thus ensuring the machining quality. Through the setting of the stopper, when the workpiece is flipped to the bottom side up, the bottom of the workpiece can be extruded by the stopper, and then clamped by the inner ring clamp block, avoiding the problem that the bottom part of the workpiece is located in the second avoidance groove and cannot be machined.

[0023] In summary, the present invention includes at least one of the following beneficial technical effects: 1. Compared with the existing processing method that requires frequent replacement of corresponding bearing seat fixtures and multiple disassembly and assembly of the roll bearing seat, the present invention can quickly realize the conversion of the clamping methods for the inner and outer sides of the workpiece, meet the processing requirements of the outer ring, inner ring and bottom end face of the workpiece, greatly improve the clamping efficiency. At the same time, because it can achieve automatic centering and axial positioning, the subsequent machining tool only needs to move along the travel route of the third avoidance groove, providing convenient conditions for the positioning of the machining tool, and further improving the machining efficiency.

[0024] 2. Through the setting of the auxiliary plate and the torsion spring, since the auxiliary plate is initially inclined towards the workpiece side, the outer ring jaws on the front and rear sides can contact the workpiece earlier than the outer ring jaw on the left side during the clamping process. Thus, using the reaction force of the torsion spring, centering operation is carried out in advance before the workpiece is locked, avoiding the problem that the outer ring jaws clamp synchronously, resulting in the workpiece being unable to move and thus unable to complete centering and positioning. At the same time, the clamping positions of the outer ring jaws on the front and rear sides are generally between the upper arc section and the lower plane section of the outer ring of the workpiece, resulting in a small contact area when clamping, making it difficult to lock. Therefore, through the auxiliary plate, surface extrusion can be carried out on the lower plane section and linear extrusion can be carried out on the upper arc section during clamping, greatly increasing the contact area and improving the locking effect.

[0025] 3. By using the setting of the sunk groove, the second spring and the preloading block, the left inner ring clamp block can contact the inner ring of the workpiece in advance through the preloading block when unfolding. Then, as it gradually unfolds, the preloading block retracts into the sunk groove by overcoming the second spring. Thus, using the reaction force of the second spring, a leftward force is always applied to the workpiece after the inner ring clamp block clamps the inner ring of the workpiece. In cooperation with the vertical plate, while assisting in clamping the workpiece, the bottom end face of the workpiece is made flush with the vertical plate, thus avoiding the problem that the bottom end face twists slightly and tilts, affecting the machining quality.

[0028] The following will further elaborate on the present invention in conjunction with the attached Figures 1-9 drawings.

[0029] An embodiment of the present invention discloses a quick locking device for a roll bearing seat.

[0030] It should be noted that in the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0031] Referring to Figures 1-9 , a quick locking device for a roll bearing housing, comprising a mounting frame 1, the mounting frame 1 including 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 upper right side of the vertical support frame 12; An attitude adjustment mechanism 2, including a cross plate 21 and a vertical plate 22, the cross plate 21 being disposed above the horizontal support frame 13, and the vertical plate 22 being fixed to the upper left end of the cross plate 21; an opening groove 23 is provided in the middle of the vertical plate 22, and a third avoidance groove 26 extending in the left-right direction is provided in the middle of the cross plate 21 and the horizontal support frame 13; A sliding assembly 3, including two groups of connecting rods 31 symmetrically fixed to the lower left side of the cross plate 21, a smooth rod 32 horizontally arranged left and right is fixed to the lower end of the connecting rod 31, and a sliding bushing 33 with a second locking bolt 34 is sleeved outside the smooth rod 32; An outer ring locking mechanism 4, including an outer ring base 41, the outer ring base 41 is connected to the corresponding sliding bushing 33 through a connecting block 35, and four groups of outer ring claws 43 that radially synchronously close or expand are evenly distributed on the outer ring base 41 to clamp or release the outer ring of the workpiece 6, and the outer ring claws 43 on the right side are located in the third avoidance groove 26; An inner ring locking mechanism 5, including 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 radially synchronously close or expand are evenly distributed on the upper end of the inner ring base 51, and the upper end of the second insertion rod 57 is detachably connected to an inner ring clamping block 55 to clamp or release the inner ring of the workpiece 6.

[0032] By adopting the above technical solution, when inner ring machining is required, the roller bearing seat workpiece 6 is placed on the cross plate 21, its outer ring is placed between the open slots 23, and at the same time its bottom is placed between the vertical plate 22 and the outer ring jaw 43 on the right side, and its bottom is placed against the vertical plate 22 with the side facing the vertical plate 22 closely attached to the vertical plate 22; then the bushing 33 is slid to the left to drive the outer ring locking mechanism 4 and the inner ring locking mechanism 5 to move to the left until the outer ring jaw 43 on the right side touches the workpiece 6 and initially presses the workpiece 6, and then the outer ring jaws 43 are synchronously closed. Since the outer ring jaw 43 on the right side 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. At the same time, the other three groups of outer ring jaws 43 on it also gradually approach the workpiece 6 until they touch the workpiece 6 and clamp the workpiece 6. After that, the sliding bushing 33 is locked by the second locking bolt 34, and the outer ring locking mechanism 4 and the inner ring locking mechanism 5 can be coaxially arranged with the outer ring of the workpiece 6 when clamping the workpiece 6, so that its clamping axis is consistent with the workpiece 6, realizing axial positioning; during this period, when the workpiece 6 is offset in the front-back direction, such as moving backward, the outer ring jaw 43 at the rear can first contact the rear side of the workpiece 6 and push it forward when closing, and then until the outer ring jaw 43 at the front touches the front side of the workpiece 6. Since the outer ring jaws 43 are evenly distributed and act synchronously, automatic centering of the workpiece 6 can be realized during the clamping process.

[0033] After that, since the inner ring locking mechanism 5 has been coaxially arranged with the outer ring of the workpiece 6 during inner ring machining, at this time, only the inner ring clamping block 55 needs to be installed on the second insertion rod 57 inside the workpiece 6, and the workpiece 6 can be clamped from the inside by adjusting the expansion of the second insertion rod 57. Then, the outer ring jaws 43 are loosened, and the outer ring of the workpiece 6 can be machined. At the same time, after the outer ring jaws 43 are expanded, they will not interfere with the subsequent machining of the bottom end face of the workpiece 6.

[0034] Therefore, compared with the existing machining method that requires frequent replacement of corresponding bearing seat fixtures 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 machining requirements of the outer ring, inner ring and bottom end face of the workpiece 6, greatly improve the clamping efficiency, and at the same time, because it can realize automatic centering and axial positioning, the subsequent machining tool only needs to move on the travel route of the third avoidance groove 26, which provides convenient conditions for the positioning of the machining tool, and further improves the machining efficiency.

[0035] Specifically, the outer ring locking mechanism 4 includes an outer ring base 41. A claw adjusting assembly 47 for controlling the closing or unfolding of the outer ring claws 43 is arranged inside the outer ring base 41. The claw adjusting assembly 47 includes an inner cylinder 475 coaxially arranged with the outer ring base 41. A first rotating shaft 476 in rotational fit is arranged inside the inner cylinder 475. A winding disc 477 is fixedly arranged on the upper part of the first rotating shaft 476. The lower end of the first rotating shaft 476 extends outside the inner cylinder 475 and is connected to a first turntable 479. A plurality of groups of first pin holes (not labeled) are correspondingly arranged on the inner cylinder 475 and the first turntable 479. Matching first pins (not shown) are arranged inside the first pin holes. Four groups of first sliding grooves 42 extending radially are evenly distributed on the outer ring base 41. First inserting rods 474 matching with the first sliding grooves 42 are arranged inside the first sliding grooves 42. A first inserting hole detachably connected to the first inserting rod 474 is arranged at the lower end of the outer ring claw 43. A first sliding block 472 connected to the first inserting rod 474 is arranged inside the inner cavity of the outer ring base 41 below the first inserting rod 474. One end of the first sliding block 472 is connected to the inner wall of the outer ring base 41 through a first spring 471. The other end of the first sliding block 472 is connected to the winding disc 477 through a traction rope 473. A wire outlet groove 478 matching with the traction rope 473 is correspondingly arranged on the inner cylinder 475.

[0036] By adopting the above technical solution, the first rotating shaft 476 can be driven to rotate by rotating the first turntable 479, so that the winding disc 477 rotates, synchronously winding the four groups of traction ropes 473. As a result, the four groups of first sliding blocks 472 move synchronously towards the inside against the elastic force of the first spring 471. Due to the arrangement of the first sliding grooves 42 and the first inserting rods 474, the outer ring claws 43 can be radially closed and moved closer to the workpiece 6 until the workpiece 6 is clamped. After clamping, the first turntable 479 is fixed by the first pin and the first inserting hole to prevent it from reversing and loosening, thereby realizing the rapid locking of the workpiece 6. On the contrary, by pulling out the first pin, the first sliding block 472 quickly resets under the elastic force of the first spring 471, realizing the rapid disassembly after the outer ring of the workpiece 6 is clamped, and further improving the overall working efficiency.

[0037] Specifically, rubber pads 44 are arranged on the inner sides of the upper ends of the outer ring claws 43. Auxiliary plates 45 are symmetrically hinged to the left and right sides of the upper ends of the front and rear outer ring claws 43. A torsion spring is arranged at the hinged position of the auxiliary plate 45 and the outer ring claw 43. The auxiliary plate 45 is initially inclined towards the workpiece 6.

[0038] Through the setting of the rubber pad 44, on the one hand, by using the buffering of the rubber pad 44 during the clamping process, scratching the outer ring of the workpiece 6 is avoided. On the other hand, the friction coefficient between the rubber pad 44 and the workpiece 6 is increased, so that the locking effect of the workpiece 6 is more reliable. Through the setting of the auxiliary plate 45 and the torsion spring, since the auxiliary plate 45 is inclined towards the workpiece 6 at the initial stage, during the clamping process, the outer ring claws 43 on the front and rear sides can contact the workpiece 6 earlier than the outer ring claws 43 on the left side. Thus, by using the reaction force of the torsion spring, the centering operation is carried out in advance before the workpiece 6 is locked, avoiding the problem that the workpiece 6 cannot move and cannot complete centering and positioning due to the synchronous clamping of the outer ring claws 43. At the same time, the clamping positions of the outer ring claws 43 on the front and rear sides are generally between the upper arc section and the lower plane section of the outer ring of the workpiece 6, resulting in a small contact area during clamping and making it difficult to lock. Therefore, through the auxiliary plate 45, surface extrusion can be carried out on the lower plane section and linear extrusion can be carried out on the upper arc section during clamping, greatly increasing the contact area and improving the locking effect.

[0039] Specifically, at least two groups of positioning holes 46 are provided on the outer ring base 41.

[0040] By adopting the above technical solution, by using the positioning holes 46, after the outer ring claws 43 clamp 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 holes 46, thereby improving the overall machining efficiency.

[0041] Specifically, the inner ring locking mechanism 5 includes an inner ring base 51. Four groups of second chutes 56 extending radially are evenly distributed on the inner ring base 51. A second rotating shaft 58 is coaxially arranged in the inner cavity of the inner ring base 51. A second turntable 59 is fixedly arranged outside the second rotating shaft 58. Four groups of arc-shaped grooves 591 are symmetrically arranged at the center of the second turntable 59. The distance between each point on the arc-shaped groove 591 in its rotating direction and the center of the second turntable 59 gradually increases. A second slider 592 that is slidably matched with the arc-shaped groove 591 is arranged in the arc-shaped groove 591. An active block 593 fixedly connected with the second slider 592 is arranged in the inner cavity of the inner ring base 51. At least two groups of second inserting rods 57 arranged radially are arranged at the upper end of the active block 593. The second inserting rods 57 pass through the second chutes 56 and are detachably connected with the inner ring clamping blocks 55 through second inserting holes 551. An adjusting handle 53 extending outwards is fixedly arranged on one side of the second turntable 59. A notch 52 matched with the adjusting handle 53 is correspondingly arranged on the side surface of the inner ring base 51. A second pin hole 54 is arranged at the outer end of the adjusting handle 53. Multiple groups of second pin holes 54 are correspondingly arranged at the upper end of the outer ring base 41. Second pins are correspondingly arranged in the second pin holes 54.

[0042] 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 slide groove 56, the second sliding block 592 slides outwardly along 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 slide groove 56 through the movable block 593 until the inner ring of the workpiece 6 is clamped, and then the adjusting handle 53 and the outer ring base 41 are connected through the second latch and the second pin hole 54 to realize the quick 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 the problem of difficulty in adjusting the inner ring clamp 55 due to interference with the outer ring claw 43, and also improves 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.

[0043] 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.

[0044] By adopting the above technical scheme, by utilizing the settings of the recessed groove 552, the second spring 554 and the pre-pressure block 553, the inner ring clamp 55 on the left side can contact the inner ring of the workpiece 6 in advance through the pre-pressure block 553 when it is unfolded, and then as it is gradually unfolded, the pre-pressure block 553 overcomes the second spring 554 and retracts into the recessed groove 552, so that the reaction force of the second spring 554 is utilized 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 a slight twisting of the bottom end face causing tilt and affecting the processing quality.

[0045] Specifically, the middle part of the transverse 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 transverse 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.

[0046] By adopting the above technical solution, with the provision of the hinge shaft 25, the first avoidance groove 14 and the first locking bolt 28, the transverse plate 21 can be flipped to be in a horizontal or vertical state and locked and fixed to the mounting bracket 1 by the first locking bolt 28, so that the bottom of the workpiece 6 can be flipped upwards, facilitating the machining of the bottom end face of the workpiece by the tool from above.

[0047] Specifically, two groups of second avoidance grooves 24 are symmetrically arranged on the transverse plate 21 on both sides before and after the third avoidance groove 26, and the vertical support frame 12 is correspondingly provided with stoppers 15 that match the second avoidance grooves 24.

[0048] Since the width of the bottom of the workpiece 6 is actually greater than the thickness of its outer ring during actual machining, it is easy to cause the workpiece 6 to tilt from the bottom to the outer ring side when it is placed on the transverse plate 21. As a result, the workpiece 6 remains tilted after the outer ring clamping jaw 43 clamps the workpiece 6, which is likely to lead to a large machining deviation in the inner ring of the workpiece 6 or even the problem of 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 fits the transverse plate 21, ensuring that the workpiece 6 is always in a horizontal state and further ensuring the machining quality; through the provision of the stoppers 15, when the workpiece 6 is flipped to the bottom facing upwards, the bottom of the workpiece 6 can be extruded by the stoppers 15, and then clamped by the inner ring clamping block 55, avoiding the problem that the bottom part of the workpiece 6 is located in the second avoidance groove 24 and cannot be machined.

[0049] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
