Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of quick-change lock cylinder assembly, in particular to an automatic precise assembly device for quick-change lock cylinder. BACKGROUND

[0002] In the automatic assembly process of the quick-change lock cylinder, as a core component, whether the sleeve can be precisely clamped and positioned plays a decisive role in the precision and reliability of subsequent assembly processes. Specifically, these subsequent processes include spring installation, torque testing, etc., all of which require the sleeve to achieve extremely high positional accuracy before assembly.

[0003] In the prior art, the clamping of the sleeve usually relies on the cooperation of rigid clamping jaws with rectangular blocks to grab the outer wall of the sleeve. This clamping method requires the sleeve to have a high degree of perpendicularity in the initial position, and the clamping jaws need to be strictly centered to ensure the stability of clamping. However, in actual production scenarios, the sleeve is often affected by factors such as mechanical vibration and material channel friction when it is fed through the conveying line, resulting in a certain degree of slight inclination of the sleeve when it enters the clamping station.

[0004] When the traditional clamping jaws encounter an inclined sleeve during the closing process, the sleeve will be forced to rotate slightly to make the outer wall of the sleeve fit the inner wall of the clamping jaws through the friction torque. Although this rotating action can achieve contact between the clamping surfaces, it will cause the center of the sleeve to deviate from the center of the clamping jaws during the clamping process. The deviation of the center of the sleeve will cause the lock cylinder assembly to be misaligned due to error accumulation in subsequent processes such as oiling, code scanning, and retainer installation. Although the existing technology can limit the rotation of the sleeve through a baffle, the orientation of the sleeve needs to be precisely controlled during the assembly process of the quick-change lock cylinder, so the baffle needs to be closely fitted with the rectangular edge of the sleeve. However, close fitting will affect the movement of the sleeve. In addition, close fitting will also increase the wear on the outer wall of the sleeve. When using a baffle to achieve positioning, if a sleeve that does not meet the standard size is encountered, the size of the sleeve cannot be screened, so incorrect sizes will also enter the next process. The incorrect size of the sleeve will adversely affect the subsequent assembly process. When a sleeve with a larger size is encountered, it is easy to get stuck between the two baffles, making it impossible for the sleeve to continue moving.

[0005] Therefore, an automatic precise assembly device for quick-change lock cylinder is proposed. SUMMARY

[0006] The present application aims to provide an automatic precise assembly device for quick-change lock cylinder, to solve the problem that when the clamping jaws clamp the sleeve, the center of the sleeve deviates from the center of the clamping jaws, thereby reducing the precision of subsequent assembly. The sleeve is fixed from the top by the clamping assembly, and during the movement of the clamping assembly, the edge of the sleeve is pushed by the adjusting assembly to adjust the position of the sleeve.

[0007] To achieve the above object, the present application provides the following technical solutions:

[0008] The quick-change lock cylinder automatic precision assembly device is used in cooperation with the sleeve and comprises a transfer assembly, a sliding plate, a fixed cylinder, a clamping assembly and an adjusting assembly, wherein the sliding plate is connected to the front side of the transfer assembly, the fixed cylinder is connected to the bottom of the sliding plate, the adjusting assembly is connected to the lower side of the fixed cylinder, the clamping assembly is connected to the inside of the fixed cylinder, the sleeve comprises a cylindrical body and a rectangular block, the clamping assembly is connected to the upper side of the rectangular block, the sleeve as a whole is moved upward in the adjusting assembly by the clamping assembly clamping the rectangular block, and when the sleeve moves upward, the edge of the rectangular block is pushed by the inner wall of the adjusting assembly to change the deflection angle of the sleeve.

[0009] In the prior art, when the sleeve is fixed by the clamping jaw, the short side of the rectangular block is mainly forward, in the above scheme, the edge of the sleeve is pushed by the adjusting assembly during the upward movement of the sleeve to adjust the deflection angle of the sleeve, so that the short side of the sleeve faces the front side, at the same time, the adjusting assembly can also align the center position of the sleeve with the center position of the clamping assembly, further improving the precision during clamping, and the adjusting assembly cooperates with the clamping assembly, which can also realize the screening of the size of the sleeve during the adjustment, so that only the sleeve meeting the standard size enters the subsequent assembly step.

[0010] Preferably, the clamping assembly comprises a suction cup, an extension rod, a bearing plate, a hollow column, a connecting plate, a mounting plate and a hose, the extension rod is connected above the sliding plate, the bearing plate is connected to the lower end of the extension rod, a plurality of hollow columns are connected to the lower side of the bearing plate, the mounting plate is connected to the lower side of the hollow column, a plurality of hoses are connected to the lower side of the mounting plate and communicate with the hollow column, the connecting plate is connected to the lower end of the hose, a plurality of suction cups are connected to the lower side of the connecting plate and communicate with the hose, the clamping assembly further comprises a negative pressure cavity, an air inlet and a conical plug, the negative pressure cavity is arranged in the connecting plate and communicates with the hose, a plurality of air inlets are arranged on the lower side of the connecting plate and communicate with the negative pressure cavity, the suction cup communicates with the negative pressure cavity, the conical plug is connected to the bottom of the connecting plate and is located at the center position, and the conical plug is made of rubber.

[0011] In the above scheme, the gas in the hollow column is extracted by the pump in the prior art, at this time the gas in the negative pressure cavity enters the hollow column, so that the negative pressure is formed in the negative pressure cavity, because the bottom of the suction cup is communicated with the negative pressure cavity, the downside of the suction cup will also form a negative pressure, so as to fix the object, the object is fixed by the suction cup, avoiding the original hard contact, causing damage to the sleeve during clamping, and the object is fixed by the suction cup, which can adapt to any deflection angle of the sleeve, and avoids damage to the sleeve caused by hard extrusion and rotation of the sleeve due to deflection angle during clamping, the through hole for mounting parts exists in the top of the sleeve in the prior art, during the process of moving the connecting plate downward to clamp the sleeve, the conical plug at the bottom of the connecting plate will first enter the through hole in the top of the sleeve before the suction cup contacts the sleeve, and push the connecting plate to move, so that the center position of the sleeve is aligned with the center position of the connecting plate, thereby realizing the preliminary positioning of the sleeve.

[0012] Preferably, the adjusting assembly comprises an adjusting sleeve, an adjusting groove, a rotating shaft and a reset spring, the adjusting sleeve is connected to the lower side of the fixed cylinder, the adjusting groove is opened on the lower side of the adjusting sleeve, the width and length of the adjusting groove gradually decrease from bottom to top, the smallest width and length of the adjusting groove are the same as those of the rectangular block, the rotating shaft is connected between the connecting plate and the mounting plate, and the reset spring is connected to the outer wall of the rotating shaft.

[0013] In the above scheme, when the clamping assembly drives the sleeve to move upward, the short side edge of the rectangular block is pushed by the inner wall of the adjusting sleeve, so that the sleeve rotates below the connecting plate, thereby adjusting the orientation of the sleeve, because the sleeve only deflects slightly when moving on the transportation line, when the edge of the rectangular block contacts the inner wall of the adjusting sleeve, the short side still contacts the short side, when the short side contacts the short side, a vertical pushing force is generated on the short side of the rectangular block, as the distance of upward movement increases, the length of the adjusting groove becomes smaller and smaller, so that the pushing range of the short side of the adjusting groove on the short side of the rectangular block increases, thereby the sleeve moves upward and deflects at the same time, until the inner wall of the adjusting groove is in close contact with the edge of the rectangular block, so that the sleeve is rotated to the correct direction.

[0014] Preferably, the inner wall of the adjusting sleeve is arc-shaped, and the arc decreases gradually from bottom to top.

[0015] In the above scheme, the arc-shaped design of the inner wall of the adjusting sleeve makes the edge of the deflected sleeve just contact the inner wall of the adjusting groove, so that point contact becomes line contact, thereby reducing the pressure between the rectangular block and the adjusting groove, and reducing the damage to the sleeve.

[0016] Preferably, the adjusting assembly further comprises a fixing groove, a sliding groove and a sliding block, the fixing groove is arranged in the middle of the upper side of the adjusting sleeve and communicates with the adjusting groove, the length and width of the fixing groove are the same as those of the rectangular block, and the two sides of the long side of the fixing groove are the left and right sides, the sliding grooves are arranged on the top of the mounting plate and the bearing plate and are perpendicular to each other, the sliding block is slidingly connected to the inside of the sliding groove, and the two sides of the sliding block are connected with compression springs, and the two sliding blocks are connected with the rotating shaft and the telescopic rod respectively.

[0017] In the above scheme, because the bearing plate is connected with the telescopic rod through the sliding groove and the sliding block, the bearing plate can move in the front-back direction at the lower end of the telescopic rod, the mounting plate is connected with the upper end of the rotating shaft through the sliding groove and the sliding block, and the rotating shaft can move left and right below the mounting plate, because the suction cup is connected to the lower side of the mounting plate and the mounting plate is connected to the lower side of the bearing plate through the hollow column, when the suction cup drives the sleeve to move upward, the sleeve can move forward, backward, left and right, when the suction cup drives the sleeve to move upward as a whole through the fixed rectangular block, the inner wall of the adjusting sleeve also pushes the sleeve to move to the center of the adjusting sleeve, so that the center of the sleeve is aligned with the center of the adjusting sleeve when the sleeve moves to the top, so that the sleeve is fixed on the moving assembly and moves with the position of the adjusting sleeve, thereby making the subsequent processing steps more accurate, because the adjusting groove and the fixing groove are in communication, after the sleeve is adjusted through the adjusting groove, the sleeve continues to move upward to make the rectangular block enter the fixing groove, because the width and length of the fixing groove are the same as those of the rectangular block, the inner wall of the fixing groove is in close contact with the inner wall of the rectangular block, thereby avoiding deviation during the movement of the moving assembly driving the sleeve, and also avoiding that the product with large size enters the inside of the adjusting groove, when the suction cup continues to move upward, the fixing groove prevents the sleeve from moving upward, so that the product with large size is separated from the suction cup and falls into the recycling frame, thereby playing a screening role, because in the assembly process of the lock cylinder, the sleeve with large or small size cannot complete the assembly of the lock cylinder, therefore, before the assembly of the lock cylinder, it is not only necessary to adjust the position of the sleeve for subsequent accurate assembly, but also necessary to accurately screen the size of the sleeve, and in the prior art, the sleeve is screened by shooting the clamped sleeve, compared with the prior art, the present application limits the upward movement of the rectangular block with large size through the adjusting groove to screen automatically, and no longer screens by confirming the size of the sleeve, thereby simplifying the structure of the equipment and reducing the cost of the equipment.

[0018] Preferably, the connecting plate is connected with a sealing assembly above, the sealing assembly comprises a movable rod, a sealing plug, a sealing ring and a vertical spring, the movable rod is connected to the inside of the negative pressure cavity and extends to the outside of the upper negative pressure cavity at the upper end, the sealing plug is connected to the lower end of the movable rod and cooperates with the air inlet, the vertical spring is connected to the lower side of the sealing plug, and the sealing ring is connected to the upper side of the connecting plate.

[0019] In the scheme, the sealing plug initially blocks the air inlet, so that the negative pressure cavity has only one outlet of the hose, when the connecting plate moves upward, the upper side of the inner wall of the fixed groove pushes the movable rod, so that the movable rod drives the sealing plug to move downward, thereby opening the air inlet on the lower side of the negative pressure cavity, so that the inner wall of the negative pressure cavity no longer generates negative pressure, at the same time, the sealing ring is tightly attached to the top of the fixed groove, so that the upper part of the fixed groove is sealed, and because the side size of the fixed groove is the same as the size of the rectangular block, when the rectangular block enters the inside of the fixed groove, the outer wall of the rectangular block is tightly attached to the inner wall of the fixed groove, and the through hole of the sleeve is blocked by the conical plug in the preliminary positioning, so that the inside of the fixed groove becomes a sealed space, at this time, the gas in the inside of the fixed groove is sucked away by the hollow column, so that the inside of the fixed groove forms negative pressure, and the rectangular block is fixed, when the size of the rectangular block is too small, the inside of the fixed groove cannot be tightly attached, so that the inside of the fixed groove cannot become a sealed space, and negative pressure cannot be formed, but at this time, the bottom of the suction cup no longer generates negative pressure, so that the sleeve of the rectangular block with a size too small falls off from the bottom of the suction cup, thereby playing a role in screening the rectangular block with a size too small, and further improving the accuracy of screening.

[0020] Preferably, a plurality of balls are connected to the inner wall of the adjusting sleeve, and the balls cooperate with the outer wall of the sleeve.

[0021] In the scheme, the balls are connected to the inner wall of the adjusting sleeve, so that when the sleeve moves upward, the edge of the rectangular block is attached to the balls, and the rolling friction of the balls is used instead of sliding friction, so as to reduce the friction force during the upward movement of the sleeve.

[0022] Compared with the prior art, the beneficial effects of the present application are:

[0023] 1. By arranging the adjusting assembly, when the inner wall of the adjusting groove at the bottom of the adjusting sleeve contacts the rectangular block above the sleeve, a vertical pushing force is generated on the short side of the rectangular block, so that the sleeve moves upward and deflects, until the inner wall of the adjusting groove is attached to the edge of the rectangular block, so that the sleeve is rotated to the correct direction, and through the cooperation of the sliding groove and the sliding block, the sleeve can move in four directions of front, back, left and right during the upward movement, and then the adjusting groove pushes the sleeve to move, so that the center position of the sleeve is aligned with the center position of the adjusting sleeve, so that the sleeve moves with the adjusting sleeve during the movement of the transplanting assembly, so that the subsequent processing steps are more accurate, and in the adjusting process, the size of the sleeve can also be screened in cooperation with the clamping assembly, so that only the sleeve with the standard size enters the subsequent assembly step, further improving the accuracy of assembly.

[0024] 2、By setting the adjusting groove and the fixed groove, when the sleeve is adjusted through the adjusting groove, the sleeve will continue to move upwards, so that the rectangular block above the sleeve is attached to the inner wall of the fixed groove, and the sleeve is limited from deflecting during movement through the fixed groove, improving the precision during assembly. At the same time, because the size of the fixed groove is the same as that of the rectangular block, when the sleeve moves upwards, the suction cup will be limited by the adjusting groove if the size of the sleeve is too large when the adjusting sleeve continues to move upwards. Because the top of the rectangular block is fixed by the suction cup, compared with the clamping jaw method, the suction cup fixing method can make the four edges of the rectangular block contact the adjusting groove at the same time, so that the size of the rectangular block can be accurately limited, so that the rectangular block with a size that is too large cannot enter the fixed sleeve, causing the sleeve to be unable to move upwards, and the product with a size that is too large is separated from the suction cup under the resistance of the adjusting groove, thereby playing a screening role.

[0025] 3、By setting the sealing assembly and the clamping assembly, the original hard contact is changed to flexible contact by using the suction cup method, thereby avoiding damage to the sleeve during clamping. And by using the suction cup to fix, any deflection angle of the sleeve can be adapted, avoiding damage to the sleeve caused by hard extrusion and rotation due to the deflection angle of the sleeve. When the connecting plate in the clamping assembly moves to the top of the fixed groove, the top of the fixed groove is tightly attached to the sealing ring and the outer wall of the rectangular block, so that the inside of the fixed groove becomes a sealed space. When the gas inside the fixed groove is sucked away by the hollow column, a negative pressure is formed inside the fixed groove, and the rectangular block is fixed. When the size of the rectangular block is too small, it cannot be tightly attached to the inside of the fixed groove, so that a sealed space cannot be formed inside the fixed groove, and a negative pressure cannot be formed, so that the sleeve of the rectangular block with a size that is too small falls off from below the suction cup, thereby playing a role in screening the rectangular block with a size that is too small.

[0039] The clamping assembly 5 further comprises a negative pressure cavity 508, air inlets 509 and a conical plug 5010. The negative pressure cavity 508 is formed in the inside of the connecting plate 505 and communicates with the hose 507. The air inlets 509 are formed in the lower side of the connecting plate 505 and communicate with the negative pressure cavity 508. The suction cup 501 communicates with the negative pressure cavity 508. When the pump extracts the gas in the hollow column 504, the gas in the negative pressure cavity 508 enters the hollow column 504 through the hose 507, so that a negative pressure is formed in the negative pressure cavity 508.

The width and length of the adjusting groove 602 gradually decrease from bottom to top. The smallest width and length of the adjusting groove 602 are the same as those of the rectangular block 102. The rotating shaft 603 is connected between the connecting plate 505 and the mounting plate 506. The reset spring 604 is connected to the outer wall of the rotating shaft 603. When the sleeve 1 is moved upward by the clamping assembly 5 and contacts the inner wall of the adjusting sleeve 601, the short side of the rectangular block 102 contacts the short side of the adjusting groove 602. When the short side contacts the short side, a vertical pushing force is generated on the short side of the rectangular block 102. As the distance of upward movement increases, the length of the adjusting groove 602 becomes smaller, so that the pushing range of the short side of the adjusting groove 602 on the short side of the rectangular block 102 increases, thereby making the sleeve 1 move upward and deflect at the same time. Until the inner wall of the adjusting groove 602 fits the edge of the rectangular block 102, the sleeve 1 is rotated to the correct direction, thereby achieving the adjustment of the orientation of the sleeve 1.

[0041] As an embodiment of the present application, referring to Figure 7 , the inner wall of the adjusting sleeve 601 is arc-shaped and the curvature gradually decreases from bottom to top, so that the point contact becomes line contact, thereby reducing the pressure between the rectangular block 102 and the adjusting groove 602 and reducing the damage to the sleeve 1.

[0045] Working principle: in use, first through the control telescopic rod 502 down, and drive the connecting plate 505 down, the existing sleeve 1 top exists installation parts through hole, in the connecting plate 505 down in the process of moving make the conical plug 5010 into the sleeve 1 top through hole, and push the connecting plate 505 moves, make the center position of sleeve 1 with the center position of connecting plate 505 alignment, so as to realize the preliminary positioning of sleeve 1, after the suction cup 501 with the top of sleeve 1 contact, again through the pump of prior art extracts the gas inside hollow column 504, make the bottom of suction cup 501 appear negative pressure, so as to through the suction cup 501 will be fixed on the top of sleeve 1, then control telescopic rod 502 shorten, through the suction cup 501 drive sleeve 1 up, in order to solve the jaw in clamping sleeve 1 when encounter inclined sleeve 1, the center of sleeve 1 with the center of jaw offset, through the suction cup 501 from the top of sleeve 1 fixed, and in the process of moving on sleeve 1 through the adjustment groove 602 in the sleeve 601 push the edge of the rectangular block 102 to adjust the position of sleeve 1, at the same time in the process of adjusting, also can filter out the sleeve 1 that does not meet the standard size;

[0046] Suction cup 501 adsorption process: when the gas inside hollow column 504 is extracted, at this time the gas inside negative pressure cavity 508 through the hose 507 into hollow column 504, so that the negative pressure cavity 508 inside form negative pressure, because the bottom of suction cup 501 with negative pressure cavity 508 communication, the downside of suction cup 501 will also form negative pressure, so as to fix the object;

[0047] Adjustment process: in the process of moving up, the short side of rectangular block 102 with the short side of adjustment groove 602 contact, so as to produce thrust on the short side of rectangular block 102, in turn make sleeve 1 drive connecting plate 505 at the lower end of rotating shaft 603 deflection, so as to make sleeve 1 rotate to the correct position, in the process of moving up sleeve 1, through the long side of adjustment groove 602 push sleeve 1 left and right movement, and make rotating shaft 603 through the slider 607 below mounting plate 506 left and right movement, through the short side of adjustment groove 602 push rectangular block 102 forward and backward movement, at this time sleeve 1 through the mounting plate 506 drive hollow column 504 forward and backward movement, because the bearing plate 503 through the sliding groove 606 and slider 607 with telescopic rod 502 connection, make the bearing plate 503 can move forward and backward below telescopic rod 502, so the hollow column 504 can drive the bearing plate 503 forward and backward movement, finally rectangular block 102 into the fixed groove 605, so as to make the center of sleeve 1 with the center of adjustment sleeve 601 alignment, when transport to the next assembly position, close the pump make the bottom of suction cup 501 no longer have negative pressure, so as to put down the sleeve 1;

[0048] When the rectangular block 102 enters the fixed slot 605, the upper side of the inner wall of the fixed slot 605 pushes the downward movement of the movable rod 701, and the movable rod 701 drives the sealing plug 702 to move downward, and opens the air inlet 509 at the lower side of the negative pressure cavity 508, so that the inner wall of the negative pressure cavity 508 no longer generates negative pressure, thereby the suction cup 501 no longer adsorbs the rectangular block 102, at the same time, the sealing ring 703 is tightly attached to the top of the fixed slot 605, and because the through hole at the top of the sleeve 1 is blocked by the conical plug 5010, the upper part of the fixed slot 605 is sealed, because the size of the fixed slot 605 is the same as the size of the rectangular block 102, when the rectangular block 102 enters the fixed slot 605, the outer wall of the rectangular block 102 will be tightly attached to the inner wall of the fixed slot 605, thereby sealing the lower side of the fixed slot 605, thereby making the inside of the fixed slot 605 a sealed space, at this time, the gas in the fixed slot 605 is sucked away by the hollow column 504, thereby forming negative pressure in the fixed slot 605, and fixing the rectangular block 102;

[0049] When encountering a rectangular block 102 with a large size, because the smallest length and width of the adjusting slot 602 are the same as the size of the standard rectangular block 102, the rectangular block 102 with a large size cannot pass through the adjusting slot 602 to enter the fixed slot 605, thereby being blocked below the fixed slot 605, unable to be driven upward by the suction cup 501, and falling off from the suction cup 501 under the extrusion of the adjusting slot 602, thereby screening the rectangular block 102 with a large size;

[0050] When encountering a rectangular block 102 with a small size, after the rectangular block 102 enters the fixed slot 605, the outer wall of the rectangular block 102 with a small size cannot be tightly attached to the inner wall of the fixed slot 605, thereby the inside of the fixed slot 605 cannot form a sealed space, and further cannot form negative pressure, but at this time, because the air inlet 509 is opened, the inside of the negative pressure cavity 508 no longer has negative pressure, thereby the bottom of the suction cup 501 no longer generates negative pressure, thereby the sleeve 1 of the rectangular block 102 with a small size falls off from below the suction cup 501, thereby playing a role in screening the rectangular block 102 with a small size.
