Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to a gear locking mechanism. Background Art

[0002] A gear is a mechanical component with teeth on the wheel rim that can continuously mesh to transmit motion and power. The application of gears in transmission has been around for a long time. At the end of the 19th century, the principle of gear cutting was developed and special machine tools and tools for gear cutting based on this principle appeared one after another. With the development of production, the smooth operation of gears has been valued and gears are widely used. During automobile manufacturing or maintenance, the gears on the engine clutch or flexible plate need to be precisely fixed in place to ensure the normal operation of the engine and transmission system. Before tightening the bolts or screws, it is necessary to ensure that the gears are correctly placed in the predetermined position, so the gears need to be locked.

[0003] After searching, we discovered that there are problems with the prior art process for locking gears. During the machining of engine clutches or flexible plates, the gears need to be positioned. However, in the prior art, the gear rotation angle must be determined in advance. Otherwise, the locking mechanism will have difficulty engaging with the gear shape, resulting in poor locking effect and hindering the operator's ability to lock the gear before machining. Therefore, based on the above search and in combination with the prior art, we proposed a gear locking mechanism to address this problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In a typical implementation of this application, please refer to Figures 1 to 5 The gear locking mechanism includes a guide base 1. A gear body 5 is provided on the bottom surface of the guide base 1. The gear body 5 is a gear on the flexible plate of the engine clutch, which needs to be locked during the processing. A plurality of fixing holes 4 for fixing the guide base 1 are opened on one side of the guide base 1. The guide base 1 can be fixed by inserting bolts into the fixing holes 4 on the guide base 1. The cylinder body 2 is fixedly installed on the inner top surface of the guide base 1. The locking assembly 3 is provided on the bottom surface of the guide base 1 for locking the gear body 5.

[0022] The locking assembly 3 includes a connecting plate 9, which is arranged on the bottom surface of the guide seat 1. A transition plate 10 is fixedly installed on the bottom surface of the connecting plate 9. A cylinder joint 8 is fixedly installed on the top surface of the connecting plate 9. One end of the telescopic shaft of the cylinder body 2 is connected to the cylinder joint 8. The cylinder body 2 and the connecting plate 9 are connected through the cylinder joint 8 so that the connecting plate 9 can be driven to move by the cylinder body 2.

[0023] The bottom surface of the transition plate 10 is fixed with a locking seat 11 by bolts. The locking seat 11 is a T-shaped hollow structure with an open top surface. The bottom surface of the locking seat 11 is provided with two threaded holes, and the bottom surface of the transition plate 10 is provided with two corresponding threaded grooves. The locking seat 11 can be installed on the bottom surface of the transition plate 10 by inserting a bolt into the threaded hole and rotating the bolt so that one end of the bolt enters the interior of the threaded groove.

[0024] The transition plate 10 is provided with a plurality of positioning pins 16. The bottom surface of the locking seat 11 is slidably connected with a locking block 14 for engaging the gear body 5. The locking block 14 is elastically connected to the positioning pin 16 by a spring 18. By allowing the locking block 14 to move on the positioning pin 16, it can adapt to different types of gear bodies 5. The locking block 14 can move according to the length of the teeth on different gear bodies 5. The locking block 14 is movably engaged with the gear body 5. The spacing between the three groups of locking blocks 14 is different from the spacing between the teeth of the gear body 5.

[0025] Among them, the cylinder body 2 drives the connecting plate 9 and the transition plate 10 to move forward, and the transition plate 10 moves forward, driving the locking seat 11 and the locking block 14 to move forward. The three groups of locking blocks 14 move forward and abut against the outer wall of the gear body 5. The abutment between the locking blocks 14 and the outer wall of the gear body 5 causes the locking blocks 14 to move along the positioning pin 16 through the spring 18. Since the intervals between the three groups of locking blocks 14 are different from the intervals between the teeth on the gear body 5, one group of locking blocks 14 must be clamped between the teeth on the gear body 5, thereby locking the gear body 5;

[0026] Two guide rods 12 are fixedly mounted on the top surface of the connecting plate 9. The guide rods 12 are slidably connected to the guide seat 1. When the connecting plate 9 drives the locking seat 11 and the locking block 14 to move, the guide rods 12 move inside the guide seat 1. The guide rods 12 cooperate with the guide seat 1 to limit the movement of the guide seat 1.

[0027] With the above technical features, through the provided gear body 5, the gear body 5 needs to be clamped in the process of tightening the screws on the gear body 5. The staff starts the cylinder body 2, and the telescopic shaft of the cylinder body 2 moves forward to drive the connecting plate 9 to move forward. The connecting plate 9 moves forward to drive the transition plate 10 to move forward. The transition plate 10 moves forward to drive the locking seat 11 and the three sets of locking blocks 14 therein to move forward until they abut against the teeth of the gear body 5. The movement of the connecting plate 9 will also drive the guide rod 12 to move inside the guide seat 1. The guide rod 12 can limit the movement of the connecting plate 9, thereby improving the stability of the connecting plate 9 when moving.

[0028] The locking block 14 abuts against the teeth of the gear body 5, causing the locking block 14 to move backward on the positioning pin 16 and compressing the spring 18. Since the spacing between the three groups of locking blocks 14 is different from the spacing between the teeth on the gear body 5, one group of locking blocks 14 will inevitably be engaged between the teeth on the gear body 5, while the other two groups will also abut against the gear body 5, thereby locking the gear body 5;

[0029] Furthermore, since the locking block 14 can be moved on the positioning pin 16 by the spring 18, the locking assembly 3 can adapt to different types of gear bodies 5. That is, the locking block 14 can be moved according to the length of the teeth on different gear bodies 5 until it abuts against the outer wall of the gear body 5, thereby locking different types of gear bodies 5, which has strong applicability.

[0030] In summary, compared with the existing technology, this technical solution does not need to position the rotation angle of the gear body 5 in advance. It is driven by the cylinder body 2, and the guide seat 1 and the cylinder body 2 cooperate to guide. It is simple and reliable, and the cylinder stroke can meet the locking of various gear bodies 5. Secondly, three sets of locking blocks 14 are used, and the arrangement spacing is inconsistent with the gear spacing. When the cylinder body 2 drives the downward pressure, no matter what angle the gear body 5 is, there is a set of locking blocks 14 inserted into the tooth profile, and the other two sets of springs 18 are compressed to lock the gear body 5. At the same time, it can adapt to different tooth profile spacings to achieve the locking function, which is convenient for subsequent tightening of the screws on the gear body 5.

[0031] The bottom surface of the transition plate 10 is provided with a mounting groove 17, and the locking block 14 is slidably connected to the mounting groove 17. The top surface of the mounting groove 17 is provided with a positioning groove 15. The outer circular wall surface of the positioning pin 16 is fixedly sleeved with the inner circular wall surface of the positioning groove 15. The positioning groove 15 can support the positioning pin 16. The spring 18 is movably sleeved on the outer circular wall surface of the positioning pin 16. One end of the spring 18 is fixedly connected to the top surface of the locking block 14, and the other end of the spring 18 is fixedly connected to the inner top surface of the mounting groove 17. The spring 18 can provide the locking block 14 with the force required for resetting.

[0032] Among them, the locking block 14 is provided, and the locking block 14 moves backward when it abuts against the gear body 5. The locking block 14 moves backward inside the mounting groove 17 and the spring 18 is compressed. The positioning groove 15 can support the spring 18. The positioning groove 15 and the mounting groove 17 cooperate to support the movement of the locking block 14.

[0033] The bottom surface of the locking block 14 is provided with a connecting groove 19, the outer circumferential wall surface of the positioning pin 16 is movably sleeved with the inner circumferential wall surface of the connecting groove 19, and the positioning pin 16 extends into the interior of the connecting groove 19;

[0034] Specifically, the locking block 14 is provided so that the locking block 14 moves along the positioning pin 16 during the downward movement, so that the positioning pin 16 moves inside the connecting groove 19 on the locking block 14. The positioning pin 16 and the connecting groove 19 cooperate to guide the movement of the locking block 14, thereby achieving a guiding effect on the locking block 14 and preventing the locking block 14 from tilting.

[0035] Two shaft sleeves 13 are fixedly installed inside the guide seat 1. The outer wall surface of the guide rod 12 is movably connected to the inner wall surface of the shaft sleeve 13. The shaft sleeve 13 reduces the friction between the guide rod 12 and the guide seat 1.

[0036] Specifically, the connecting plate 9 is provided, and during the movement of the connecting plate 9, the guide rod 12 is driven to move in the internal sleeve 13 of the guide seat 1. The sleeve 13 can reduce the friction between the guide rod 12 and the guide seat 1, thereby improving the smoothness of the movement of the connecting plate 9 and the locking block 14.

[0037] Two mounting plates 6 are fixedly installed on the top surface of the guide seat 1. A connecting hole 7 is opened on one side of the mounting plate 6. Through the set mounting plate 6, the staff puts the bolts into the connecting hole 7 on the mounting plate 6 to fix the guide seat 1 in the appropriate position.

[0038] Working principle: Through the provided cylinder body 2, the cylinder body 2 drives the connecting plate 9 and the transition plate 10 to move forward, and the transition plate 10 moves forward, driving the locking seat 11 and the locking block 14 to move forward. The three groups of locking blocks 14 move forward and abut against the outer wall of the gear body 5. The abutment between the locking blocks 14 and the outer wall of the gear body 5 causes the locking blocks 14 to move along the positioning pin 16 through the spring 18. Since the intervals between the three groups of locking blocks 14 are different from the intervals between the teeth on the gear body 5, one group of locking blocks 14 must be clamped between the teeth on the gear body 5, thereby locking the gear body 5.

[0039] When the connecting plate 9 drives the locking seat 11 and the locking block 14 to move, the guide rod 12 moves inside the guide seat 1 . The guide rod 12 cooperates with the guide seat 1 to limit the movement of the guide seat 1 .

[0040] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
