Description

Technical Field

[0001] This utility model relates to the field of guide rail drilling fixture technology, and more specifically, it relates to a guide rail drilling fixture. Background Technology

[0002] In the existing technical field, guide rail drilling fixtures are important auxiliary tooling equipment in machining. Their design quality and functionality directly affect the accuracy and production efficiency of guide rail drilling. However, existing guide rail drilling fixtures have many technical problems that urgently need to be solved: In practical applications, these fixtures are usually not convenient for completely clamping and fixing the guide rail. Most designs only fix one side of the guide rail, failing to achieve all-round clamping. This one-sided fixing method makes the guide rail prone to slight displacement or vibration during drilling, seriously affecting the drilling accuracy and positional accuracy. More importantly, when the drill bit applies pressure, the one-sided fixed guide rail may tilt or shift, resulting in drilling angle deviation, irregular hole diameter, and even workpiece damage or safety accidents due to insecure fixing. In addition, the pressure distribution on the guide rail surface is uneven due to the one-sided fixing method. Long-term use may lead to guide rail deformation or surface damage, reducing the service life of the guide rail and product quality, ultimately having a significant adverse impact on the overall machining quality and production efficiency.

[0003] Secondly, while some improved devices in the existing technology attempt to press the guide rail onto the base by using cylinders equipped with movable blocks and pressure blocks, which improves the fixing effect to a certain extent, this design still has obvious limitations. In practical applications, depending on the processing requirements of different working conditions and guide rail specifications, it is often necessary to change or adjust the length or thickness of the movable block to adapt to different workpiece sizes and processing requirements. However, the installation and disassembly of the movable block in such devices is usually complex and requires the assistance of various tools such as special wrenches and Allen wrenches. The disassembly and assembly process is cumbersome and time-consuming, and the whole process may consume a lot of time and physical strength. Especially in the production environment of batch and multi-variety processing, the cumbersome movable block replacement operation seriously reduces production efficiency and increases the labor intensity and fatigue of workers. This design, which makes it difficult to easily replace the movable block, has become an important factor restricting the flexible application and efficiency improvement of guide rail drilling fixtures, and has a significant adverse impact on the production line's capacity and cost control. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a guide rail drilling fixture to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a guide rail drilling fixture, comprising a base, on which a fixing device is mounted, the fixing device comprising a first cylinder, a first piston rod, a mounting bracket, a movable plate, a movable block, and a pressure block, the first cylinder being detachably mounted on one side of the base, the bottom end of the first piston rod being connected to the output end of the first cylinder, one end of the movable block being rotatably connected to the top end of the first piston rod, the mounting bracket being detachably mounted on one side of the base, both ends of the movable plate being rotatably connected to the movable block and the mounting bracket respectively, the pressure block being detachably mounted on the underside of the movable block, and a snap-fit ​​device being mounted on the outer side of both the movable plate and the movable block, the snap-fit ​​device comprising a snap-fit ​​sleeve. The system comprises a snap-fit ​​rod, an adapter block, an elastic plate, an adapter sleeve, a snap-fit ​​plate, a release sleeve, a release groove, a release block, a snap-fit ​​block, and a snap-fit ​​groove. The snap-fit ​​sleeve is detachably fitted onto the outside of the snap-fit ​​rod. The adapter block is fixedly installed on one side of the top of the elastic plate. The elastic plate slides through the snap-fit ​​plate on one side of the snap-fit ​​sleeve and connects with the adapter sleeve. The adapter sleeve is slidably positioned on one side of the snap-fit ​​sleeve. The snap-fit ​​plate is fixedly connected to one end of the snap-fit ​​sleeve and the snap-fit ​​rod, respectively. The release sleeve is slidably fitted onto the outside of the snap-fit ​​sleeve. The release groove is formed in the release sleeve. The release block slides in the release groove. The snap-fit ​​block is fixedly connected to one side of the release block. One end of the snap-fit ​​block is snapped into the snap-fit ​​groove, which is formed on the outside of the snap-fit ​​rod.

[0008] The present invention is further configured such that a limiting rod is detachably provided on the base, a limiting groove is provided at the top of the base, and a limiting block is slidably provided in the limiting groove. This design provides precise positioning and fixing functions in the length direction of the guide rail, effectively preventing axial movement of the guide rail during the processing and significantly improving the accuracy of the drilling position.

[0009] The present invention is further configured such that a second cylinder is detachably provided on the inner side of the base, and a second piston rod is connected to the output end of the second cylinder. One end of the second piston rod is detachably connected to the bottom end of the limiting block. This pneumatic drive structure realizes the automated and precise control of the limiting block. Compared with manual operation, the pneumatic control method provides a more stable and continuous clamping force, while eliminating human operation errors, ensuring the consistency and controllability of clamping pressure, and improving the repeatability of drilling and the consistency of batch processing.

[0010] The present invention is further configured such that a limiting rod is detachably provided on the base, a limiting groove is provided at the top of the base, and a limiting block is slidably provided in the limiting groove. This structure forms an effective fixing mechanism in the width direction of the guide rail. The sliding cooperation between the limiting groove and the limiting block realizes the precise control of the lateral position of the guide rail. This lateral fixing mechanism effectively prevents the lateral displacement of the guide rail during the drilling process. Together with the length direction fixing, it forms a two-dimensional positioning system that cooperates with each other, ensuring the absolute stability of the guide rail in the plane and providing the necessary prerequisite for high-precision drilling.

[0011] The present invention is further configured such that a third cylinder is detachably provided on the inner side of the base, and a third piston rod is connected to the output end of the third cylinder. One end of the third piston rod is detachably connected to the bottom end of the limiting block. This pneumatic control system makes the movement of the limiting block precise and controllable. The pneumatic drive mode realizes a uniform and continuous clamping force in the width direction of the guide rail. The synchronous control of multiple third cylinders ensures the balanced distribution of clamping force, effectively preventing any form of lateral displacement of the guide rail during the processing, and further improving the lateral control function of the three-dimensional fixing system.

[0012] The present invention is further configured such that a top plate is connected to the top of the snap-fit ​​sleeve, and an adapter spring is movably fitted on the outside of the snap-fit ​​sleeve. The two ends of the adapter spring are respectively connected to the top plate and the release sleeve. This elastic connection structure design ensures the automatic reset function of the release sleeve. This self-reset design reduces the operation steps and improves the disassembly and assembly efficiency.

[0013] The present invention is further configured such that the adapter block is a cylindrical structure and the two sides of the release sleeve are rounded. This carefully designed geometry greatly enhances the smoothness of operation of the snap-fit ​​device. The cylindrical adapter block provides a stable sliding guide, and the rounded release sleeve reduces the jamming and wear that may be caused by sharp edges. At the same time, the rounded structure allows the release sleeve to smoothly push the adapter block and guide the elastic plate to tilt. The overall structure forms a mechanism with minimized resistance.

[0014] The present invention is further configured such that the locking groove is a ring structure design, and the release groove and the release block are both inclined structure designs. This geometric configuration forms an efficient and stable locking and unlocking mechanism. The ring-shaped locking groove enables the locking block to maintain a stable locked state at any angle.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a guide rail drilling fixture, which has the following advantages:

[0017] 1. The fixing device, through the ingenious cooperation of the base, first cylinder, first piston rod, mounting bracket, movable plate, movable block, and pressure block, completely solves the technical problem of existing guide rail drilling jigs being inconvenient to thoroughly clamp and fix the guide rail. This device design achieves three-dimensional omnidirectional clamping of the guide rail. The limiting rod and limiting block cooperate to clamp and fix the guide rail in the length direction; the limiting rod and limiting block cooperate to clamp and fix the guide rail in the width direction; and the movable block drives the pressure block to press and fix the guide rail in the thickness direction, forming a complete three-dimensional clamping system. This triple clamping mechanism effectively prevents slight displacement or vibration of the guide rail during drilling, significantly improving… This device ensures drilling precision and positional accuracy. Especially when the drill bit applies pressure, the omnidirectional clamping guide rail prevents tilting or shifting, avoiding quality issues such as drilling angle deviation and irregular hole diameter. It also prevents workpiece damage or safety accidents caused by insecure fixing. Furthermore, the three-way clamping results in a more uniform pressure distribution on the guide rail surface, preventing deformation or surface damage even with long-term use. This effectively extends the guide rail's lifespan and product quality, providing a reliable guarantee for overall processing quality and production efficiency. The fixing device can also clamp and fix two guide rails simultaneously, greatly improving production efficiency and meeting the needs of mass production.

[0018] 2. The snap-fit ​​device is precisely assembled from multiple components, including a snap-fit ​​sleeve, snap-fit ​​rod, adapter block, elastic plate, adapter sleeve, snap-fit ​​plate, release sleeve, release groove, release block, snap-fit ​​block, and snap-fit ​​groove. It cleverly solves the technical deficiency of existing technologies where the installation and removal of movable blocks requires tools. This snap-fit ​​device adopts a unique quick-release design. The user only needs to pull the release sleeve to one side, which will cause the inner inclined release groove to slide. The release block then pulls the snap-fit ​​block out of the snap-fit ​​groove. Simultaneously, the release sleeve, through its outer rounded corner design, pushes the adapter block, causing the elastic plate to tilt outwards. This achieves rapid removal of the snap-fit ​​sleeve and snap-fit ​​rod. The entire disassembly process requires no tools, is simple and intuitive, and greatly reduces disassembly and assembly time and labor intensity. Similarly, during installation, simply pass the snap-fit ​​rod through the mounting hole from one side. Then, the snap-fit ​​sleeve is fitted onto the outside of the snap-fit ​​rod from the other side. The fitting, elastic plate, release sleeve, and other components automatically complete positioning and locking, realizing convenient installation of the movable block. This tool-less, automated, and rapid disassembly and assembly design makes it extremely convenient to replace the movable block according to the processing requirements of different working conditions and different specifications of guide rails, greatly saving production time. Especially in the production environment of batch and multi-variety processing, it significantly improves production efficiency, reduces the labor intensity and fatigue of workers, and completely solves the problem of tedious and time-consuming replacement of movable blocks. In addition, the various components of the snap-fit ​​device, such as the top plate at the top of the snap-fit ​​sleeve, the snap-fit ​​groove with an annular structure design, and the release groove and release block with an inclined structure design, are precisely matched to ensure the stability of the connection and the convenience of disassembly and assembly, providing strong technical support for the flexible application and efficiency improvement of guide rail drilling fixtures.

One end of the movable block 6 is rotatably connected to the top end of the first piston rod 3. The mounting bracket 4 is detachably mounted on one side of the base 1. Both ends of the movable plate 5 are rotatably connected to the movable block 6 and the mounting bracket 4, respectively. The pressure block 7 is detachably mounted on the lower side of the movable block 6. A snap-fit ​​device is mounted on the outer side of both the movable plate 5 and the movable block 6. The snap-fit ​​device includes a snap-fit ​​sleeve 8, a snap-fit ​​rod 9, an adapter block 10, an elastic plate 11, an adapter sleeve 12, and a snap-fit ​​plate 1. 3. Release sleeve 14, release groove 15, release block 16, snap-fit ​​block 17 and snap-fit ​​groove 18. The snap-fit ​​sleeve 8 is detachably sleeved on the outside of the snap-fit ​​rod 9. The adapter block 10 is fixedly installed on one side of the top of the elastic plate 11. The elastic plate 11 slides through the snap-fit ​​plate 13 provided on one side of the snap-fit ​​sleeve 8 and connects with the adapter 12. The adapter 12 is slidably set on one side of the snap-fit ​​sleeve 8. The snap-fit ​​plate 13 is fixedly connected to one end of the snap-fit ​​sleeve 8 and the snap-fit ​​rod 9 respectively. The release sleeve 14 is slidably sleeved on the outside of the snap-fit ​​sleeve 8. The release groove 15 is opened in the release sleeve 14. The release block 16 is slidably located in the release groove 15. The snap-fit ​​block 17 is fixedly connected to one side of the release block 16. One end of the snap-fit ​​block 17 is snapped into the snap-fit ​​groove 18. The snap-fit ​​groove 18 is opened on the outside of the snap-fit ​​rod 9.

[0029] A limiting rod 19 is detachably provided on the base 1, and a limiting groove 20 is provided at the top of the base 1, in which a limiting block 21 is slidably provided.

[0030] A second cylinder 22 is detachably provided on the inner side of the base 1. A second piston rod 23 is connected to the output end of the second cylinder 22. One end of the second piston rod 23 is detachably connected to the bottom end of the limiting block 21.

[0031] A limiting rod 24 is detachably provided on the base 1, and a limiting groove 25 is opened at the top of the base 1, in which a limiting block 26 is slidably provided.

[0032] A third cylinder 27 is detachably provided on the inner side of the base 1. A third piston rod 28 is connected to the output end of the third cylinder 27. One end of the third piston rod 28 is detachably connected to the bottom end of the limiting block 26.

[0033] In this embodiment, when the device is needed, the guide rail to be drilled is first placed on the top of the base 1. Then, multiple third cylinders 27 are opened simultaneously. The third cylinders 27 are retracted through the third piston rod 28 connected to the output end, causing the third piston rod 28 to move towards the third cylinder 27. Then, the third piston rod 28 drives the limiting block 26 at one end to slide along the limiting groove 25, so that the limiting block 26 cooperates with the limiting rod 24 to clamp the guide rail in the width direction. At the same time, the second cylinder 22 is opened, so that the second cylinder 22 drives the second piston rod 23 connected to the output end to push outward, so that the second piston rod 23 drives the limiting block 21 connected to one end to move along the limiting groove 25. The groove 20 slides, allowing the limiting block 21 to clamp the guide rail along its length direction in conjunction with the limiting rod 19. Finally, the first cylinder 2 is opened, causing the first piston rod 3 connected to the output end of the first cylinder 2 to extend upward. Then, the first piston rod 3 drives the movable block 6 connected to one end to move. Since the movable block 6 is rotatably connected to the mounting frame 4 through the movable plate 5, forming a lever fulcrum, the other end of the movable block 6 drives the pressure block 7 to descend, causing the pressure block 7 to press the guide rail onto the base 1, thus achieving pressure on the guide rail in the thickness direction. Through triple clamping, comprehensive clamping and fixing in three directions are achieved, ensuring the stability and processing accuracy of drilling. This equipment can clamp and fix two guide rails simultaneously.

[0034] Please see Figures 3-5 As a further implementation of the overall equipment: the top of the snap-fit ​​sleeve 8 is connected to a top plate 29, and the outer side of the snap-fit ​​sleeve 8 is movably fitted with an adapter spring 30, the two ends of the adapter spring 30 being connected to the top plate 29 and the release sleeve 14 respectively.

[0035] The adapter block 10 has a cylindrical structure design, and the release sleeve 14 has a rounded corner design on both sides.

[0036] The snap-fit ​​groove 18 is a ring structure design, and the release groove 15 and the release block 16 are both inclined structure designs.

[0037] More specifically, when the movable block 6 needs to be replaced, first pull the release sleeve 14 to one side, causing the release sleeve 14 to slide along the inner inclined release groove 15. Then, the release block 16 moves in the release groove 15 and causes the one-sided locking block 17 to slide outward, so that the locking block 17 is gradually pulled out of the locking groove 18. At the same time, the release sleeve 14 will cooperate with the top plate 29 to press the adapter spring 30. During this process, due to the rounded corner design of the outermost edge of the release sleeve 14, the release sleeve 14 pushes the adapter block 10 outward, causing the adapter block 10 to tilt the elastic plate 11 outward. Then, the release sleeve 14 will move completely to the other end of the adapter block 10, and then the elastic plate 11 will drive the adapter block 10 to reset and return to the correct position. Simultaneously, the release sleeve 14, in conjunction with the top plate 29, thoroughly presses the adapter spring 30. Then, the locking sleeve 8 is pulled outwards together, causing it to disengage from the outside. The locking rod 9 is then pulled to the other side, completely removing the locking sleeve 8 and the locking rod 9. The release sleeve 14 is then released, and the adapter spring 30 pushes the release sleeve 14 to slide back to its original position, causing the release groove 15 to reset. This causes the release block 16 to move and reset the locking block 17. Then, the other end of the adapter sleeve 12 pushes the elastic plate 11 to slide through the adapter block 10, causing the elastic plate 11 to slide along one side of the adapter sleeve 12. Following the same steps, the other locking sleeves 8 and locking rods 9 are removed, thus removing the movable block 6. Replace block 6. After replacement, align the corresponding mounting holes on movable block 6 with the mounting holes on movable plate 5 and one end of the first piston rod 3. Then, pass the locking rod 9 through the mounting hole from one side, and then fit the locking sleeve 8 onto the outside of the locking rod 9 from the other side. Then, one side of the adapter 12 will first contact the mounting surface, and then the adapter 12 will stop moving. Then, the locking sleeve 8 will drive the other parts to continue moving. Then, the elastic plate 11 will slide along the locking plate 13 on one side of the locking sleeve 8, and the elastic plate 11 will push the release sleeve 14 to slide through the adapter block 10 on one side. Then, the release sleeve 14 will once again cooperate with the top plate 29 to press the adapter spring 30, and the release sleeve 14 will once again drive the inner release groove 15 to slide, and then release... The release block 16 will again drive the locking block 17 to slide outward. When the locking sleeve 8 is fully engaged with the outer side of the locking rod 9, the adapter spring 30 is compressed to its limit. At this time, the pressure applied by the adapter spring 30 to the release sleeve 14 is greater than the deformation force applied by the elastic plate 11. Due to the rounded corner design at the outermost corner of the release sleeve 14, the release sleeve 14 will push the adapter block 10 outward again, causing the adapter block 10 to drive the elastic plate 11 to tilt outward again. Then the release sleeve 14 will slide into the inner side of the elastic plate 11 and perform a complete sliding reset, so that the release sleeve 14 is on the side of the adapter block 10. Then the elastic plate 11 will drive the adapter block 10 to reset and return to the correct position, thereby realizing the convenient disassembly and assembly of the movable block 6, and thus realizing the convenient replacement of the movable block 6.

[0038] In summary, when using or operating the overall equipment: First, place the guide rail to be drilled on top of the base 1. Then, simultaneously open multiple third cylinders 27. The third cylinders 27 retract via the third piston rod 28 connected to their output ends, causing the piston rod 28 to move towards the third cylinder 27. The piston rod 28 then drives a limiting block 26 at one end to slide along the limiting groove 25, allowing the limiting block 26 to clamp the guide rail in the width direction in conjunction with the limiting rod 24. Simultaneously, open the second cylinder 22, causing it to drive the second piston rod 23 connected to its output end to push outwards, causing the second piston rod 23 to move the limiting block 24 connected to its end. 1. Slide along the limiting groove 20, so that the limiting block 21 cooperates with the limiting rod 19 to clamp the guide rail in the length direction. Finally, open the first cylinder 2, so that the first piston rod 3 connected to the output end of the first cylinder 2 extends upward. Then the first piston rod 3 drives the movable block 6 connected to one end to move. Since the movable block 6 is rotatably connected to the mounting frame 4 through the movable plate 5 to form a lever fulcrum, the other end of the movable block 6 drives the pressure block 7 to descend, so that the pressure block 7 presses the guide rail onto the base 1, realizing the pressing of the guide rail in the thickness direction. Through triple clamping, comprehensive clamping and fixing in three directions is achieved, ensuring the stability and processing accuracy of drilling. This equipment can clamp and fix two guide rails at the same time.

[0039] When the movable block 6 needs to be replaced, first pull the release sleeve 14 to one side, causing the release sleeve 14 to slide along the inner inclined release groove 15. Then, the release block 16 moves in the release groove 15 and causes the locking block 17 on one side to slide outward, so that the locking block 17 is gradually pulled out of the locking groove 18. At the same time, the release sleeve 14 will cooperate with the top plate 29 to press the adapter spring 30. During this process, due to the rounded corner design of the outermost corner of the release sleeve 14, the release sleeve 14 pushes the adapter block 10 outward, causing the adapter block 10 to tilt the elastic plate 11 outward. Then, the release sleeve 14 will move completely to the other end of the adapter block 10, and then the elastic plate 11 will drive the adapter block 10 to reset and return to its original position. Release sleeve 14, in conjunction with top plate 29, thoroughly presses the adapter spring 30. Then, the locking sleeve 8 is pulled outward together, causing it to disengage from the outside. The locking rod 9 is then pulled to the other side, completely removing the locking sleeve 8 and locking rod 9. Release sleeve 14 is then released, and adapter spring 30 pushes release sleeve 14 to slide back to its original position, causing release groove 15 to reset. This causes release block 16 to move locking block 17 back to its original position. The other end of adapter sleeve 12 then pushes elastic plate 11 to slide via adapter block 10, causing elastic plate 11 to move one side of adapter sleeve 12. Following the same steps, the other locking sleeves 8 and locking rods 9 are removed, allowing removal of movable block 6. After replacement, align the corresponding mounting holes on the movable block 6 with the mounting holes on the movable plate 5 and one end of the first piston rod 3. Then, pass the locking rod 9 through the mounting hole from one side, and then fit the locking sleeve 8 onto the outside of the locking rod 9 from the other side. The adapter 12 will first contact the mounting surface, and then the adapter 12 will stop moving. The locking sleeve 8 will then drive the other parts to continue moving. The elastic plate 11 will slide along the locking plate 13 on one side of the locking sleeve 8, and the elastic plate 11 will push the release sleeve 14 to slide through the adapter block 10 on one side. Then the release sleeve 14 will again cooperate with the top plate 29 to press the adapter spring 30, and the release sleeve 14 will again drive the inner release groove 15 to slide, and then release. Block 16 will again drive the snap-fit ​​block 17 to slide outward. When the snap-fit ​​sleeve 8 is fully engaged with the outside of the snap-fit ​​rod 9, the adapter spring 30 is compressed to its limit. At this time, the pressure applied by the adapter spring 30 to the release sleeve 14 is greater than the deformation force applied by the elastic plate 11. Due to the rounded corner design at the outermost corner of the release sleeve 14, the release sleeve 14 will push the adapter block 10 outward again, causing the adapter block 10 to drive the elastic plate 11 to tilt outward again. Then the release sleeve 14 will slide into the inner side of the elastic plate 11 and perform a complete sliding reset, so that the release sleeve 14 is on one side of the adapter block 10. Then the elastic plate 11 will drive the adapter block 10 to reset and return to the correct position, thereby realizing the convenient disassembly and assembly of the movable block 6, and thus realizing the convenient replacement of the movable block 6.
