Description

Technical Field

[0001] This invention relates to the field of gear ring milling technology, and in particular to a gear ring machining structure and device for construction machinery. Background Technology

[0002] Construction projects often require various specialized mechanical equipment. Among construction machinery, the gear ring is one of the core transmission components, and its performance directly determines the power transmission efficiency, operational stability, and service life of the equipment.

[0003] After the gear ring is produced, its end face and outer circle often have a lot of burrs, which need to be removed by milling. Since each batch of gear rings to be milled is not completely different (size, type), and the traditional milling structure often adapts the milling operation by stopping work to change the milling cutter, this method will leave a long downtime. Therefore, in order to optimize this step, an improved gear ring processing structure and device are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a structure and device for processing gear rings in construction machinery, which can flexibly adapt to different gear rings to be processed and shorten downtime.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a gear ring processing structure for construction machinery, including a clamping assembly, wherein the gear ring to be processed is fixed and moved by the clamping assembly, and a milling assembly for processing the gear ring is provided above the clamping assembly;

[0006] The milling assembly includes a milling cutter mounting assembly and an output assembly disposed on the milling cutter mounting assembly. The output assembly is used to connect to an external kinetic energy output device to drive the milling cutter mounting assembly to mill the gear ring.

[0007] The milling cutter mounting assembly includes a mounting bracket with symmetrically distributed grooves. Milling frames are slidably mounted in the grooves. Mounting blocks for mounting milling cutters are fixedly installed on the outer sides of both milling frames. Different types of milling cutters can be mounted on the two mounting blocks to mill different types of gear rings.

[0008] The output components include a drive assembly fixedly mounted on the mounting bracket, an adjustment assembly fixedly connected to the two milling heads, and a guide assembly that guides the linear displacement of the milling heads and maintains the circular milling trajectory.

[0009] A further embodiment of the present invention is that the drive assembly includes a drive cylinder whose outer side is fixedly connected to the mounting bracket, and a gear ring is fixedly mounted on the outer side of the drive cylinder. The gear ring meshes with a drive gear for connecting to an external kinetic energy output device.

[0010] By adopting the above technical solution, the drive gear drives the drive cylinder to rotate synchronously through the gear ring.

[0011] A further configuration of the present invention is that the adjusting assembly includes a connecting frame fixedly connected to one of the milling frames on the outside and a pull block fixedly connected to the end of the connecting frame away from the milling frame.

[0012] By adopting the above technical solution, the connecting frame drives the milling frame to move synchronously, thereby enabling the milling cutters on the milling frame to maintain synchronous movement.

[0013] A further feature of the present invention is that the pull block is provided with a pull groove, the front and rear sides of the pull groove are open structures, and a mating block is slidably installed inside the pull groove, with the bottom ends of the two mating blocks respectively fixedly connected to the two piston rods of the first cylinder.

[0014] By adopting the above technical solution, the piston rod pulls the mating block to achieve left and right movement.

[0015] A further feature of the present invention is that the groove is an arc structure coaxial with the milling trajectory of the milling frame, and the outer contour of the mating block matches the groove.

[0016] By adopting the above technical solution, when the pull block needs to rotate after reaching the milling station, it will not be blocked by the mating block during rotation.

[0017] A further embodiment of the present invention is that the guiding assembly includes a guiding disk disposed within the drive cylinder and a limiting assembly mounted on the guiding disk.

[0018] By adopting the above technical solution, the pull block is prevented from shifting outward due to centrifugal force when it rotates with the mounting frame.

[0019] A further feature of the present invention is that a positioning rod is fixedly installed on the outside of the pull block, and the guide plate includes a disc body coaxially disposed inside the drive cylinder and not in contact with the drive cylinder. A first annular groove and a second annular groove are provided on the bottom side of the disc body to maintain coaxiality. The first annular groove and the second annular groove are connected by a connecting groove. The top end of the positioning rod is slidably connected to the first annular groove, the second annular groove and the connecting groove.

[0020] By adopting the above technical solution, the stability of the positioning rod during sliding is improved.

[0021] A further feature of the present invention is that a limiting groove penetrating both the upper and lower surfaces is provided on the connecting groove. The limiting component includes a limiting block that is slidably connected to the limiting groove on the outside and a synchronization plate that is fixedly connected to the outside of the limiting block. The synchronization plate is fixedly connected to the piston rod of the second cylinder through a stand. When not milled, the bottom surface of the limiting block is coplanar with the upper surface of the connecting groove, and there are two limiting grooves and two limiting blocks.

[0022] By adopting the above technical solution, the limiting block moves downward through the movement of the synchronous plate to cut off the connecting groove.

[0023] A further provision of the present invention is that the outer side of the disc is fixedly connected to a first support frame for connecting to an external support structure, and the bottom end of the first support frame is fixedly connected to a first cylinder via a second support frame.

[0024] By adopting the above technical solution, the two first cylinders can be connected to the external support structure through the second support frame.

[0025] The beneficial effects of this invention are:

[0026] The device allows for pre-installation of the milling cutters to be used. After the gear ring is clamped, the appropriate milling cutter can be moved to the appropriate milling station under the adjustment of the adjustment component and then positioned. Later, the drive component drives the milling cutter to rotate and complete the appropriate burr milling. When it is necessary to change the milling cutter, the two milling cutters can be quickly switched to reduce the downtime in between. This automation improves processing efficiency. At the same time, this structure is compatible with the working environment of various existing gear ring processing modes. The installation method is simple and quick, without the need for additional customized installation and matching structures, thus saving installation and usage costs and making it highly applicable.

Detailed Implementation

[0036] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] This invention specifically provides a machining structure for gear rings in construction machinery. Please refer to [the relevant documentation]. Figures 1-6 The device includes a clamping assembly 1, through which the gear ring to be processed is fixed and moved. A milling assembly 2 for processing the gear ring is provided above the clamping assembly 1. A clamping frame 11 is provided on the clamping assembly 1. The clamping assembly 1 can move the two clamping frames 11 closer or further apart to clamp the inner wall of the gear ring outward. At the same time, the clamping frame 11 can move up and down to drive the gear ring to move up and down synchronously, thereby moving the gear ring during milling. In practice, the type of clamping assembly 1 can be an existing gear ring processing clamping device to meet the above functional requirements. The relevant equipment technology is relatively mature, so it will not be described in detail here.

[0038] The milling assembly 2 includes a milling cutter mounting assembly 3 and an output assembly 4 disposed on the milling cutter mounting assembly 3. The output assembly 4 is used to connect to an external kinetic energy output device to drive the milling cutter mounting assembly 3 to mill the gear ring.

[0039] Specifically, the milling cutter mounting assembly 3 includes a mounting bracket 31. The mounting bracket 31 has symmetrically distributed grooves 32. The grooves 32 are distributed symmetrically on the mounting bracket 31 and extend through the upper and lower sides of the mounting bracket 31. A milling frame 33 is slidably mounted in the groove 32. The top of the milling frame 33 slides linearly along the groove 32. Mounting blocks 34 for mounting milling cutters are fixedly provided on the outer sides of both milling frames 33. The two mounting blocks 34 can be used to mill different types of gear rings by mounting different types of milling cutters. The type of mounting block 34 can be a mounting structure adapted to the mounting of different external milling cutters. The mounting block 34 is provided with mounting screw holes to facilitate the bolt connection between the milling cutter and the mounting block 34.

[0040] Furthermore, the output component 4 includes a drive component 5 fixedly mounted on the mounting frame 31, an adjustment component 6 fixedly connected to the two milling frames 33, and a guide component 7 that guides the linear displacement of the milling frames 33 and maintains the circular milling trajectory. The adjustment component 6 drives one of the milling frames 33 to move in the direction of the gear ring, so that when the drive component 5 drives the mounting frame 31 to rotate, the milling cutter can rotate outside the gear ring for pre-processing the burrs on the surface of the gear ring.

[0041] The drive assembly 5 includes a drive cylinder 51 that is fixedly connected to the mounting bracket 31 on the outside. A gear ring 52 is fixedly mounted on the outside of the drive cylinder 51. The gear ring 52 meshes with a drive gear 53 for connecting to an external kinetic energy output device. In practice, after the external kinetic energy output device drives the drive gear 53 to rotate, the drive gear 53 can drive the drive cylinder 51 to rotate synchronously through the gear ring 52.

[0042] The mounting bracket 31 has an assembly slot 35, and the outer side of the drive cylinder 51 is inserted into the assembly slot 35 to facilitate the installation of the drive cylinder 51 on the mounting bracket 31. At the same time, the bottom end of the drive cylinder 51 is bolted to the mounting bracket 31 so that the drive cylinder 51 can drive the mounting bracket 31 to rotate synchronously after rotation, so that the milling cutter installed on the mounting bracket 31 can rotate synchronously around the outer side of the gear ring.

[0043] Specifically, in order to enable one of the matching milling cutters to perform close milling with the matching gear ring, the adjusting component 6 includes a connecting frame 61 fixedly connected to one of the milling frames 33 on the outside and a pull block 62 fixedly connected to the end of the connecting frame 61 away from the milling frame 33. When the pull block 62 is subjected to force to move closer or further away from the gear ring, the connecting frame 61 can drive the milling frame 33 to move synchronously, so that the milling cutter on the milling frame 33 can keep moving synchronously to perform milling on the gear ring.

[0044] In practice, the pull block 62 is provided with a pull groove 63. The front and rear sides of the pull groove 63 are open structures, and a mating block 64 is slidably installed inside the pull groove 63. The bottom ends of the two mating blocks 64 are respectively fixedly connected to the two piston rods of the first cylinder 65. It is worth noting that the mating blocks 64 at both ends are respectively connected to an independent first cylinder 65. The two first cylinders 65 are symmetrically arranged to facilitate left and right movement by pulling the mating blocks 64 through the piston rod.

[0045] By adopting the above technical solution, when it is necessary to use one end of the milling cutter for milling operations, the piston rod of the first cylinder 65 at the corresponding end can be retracted, so that the mating block 64 can move towards the gear ring, thereby driving the pull block 62 to move, and finally the milling cutter completes synchronous movement, contacts the gear ring and reaches the milling station.

[0046] The groove 63 has an arc structure that is coaxial with the milling trajectory of the milling frame 33. The outer contour of the mating block 64 matches the groove 63, so that when the pull block 62 needs to rotate after reaching the milling station, it will not be blocked by the mating block 64 during rotation, so that when the mounting frame 31 rotates, the pull block 62 can meet the corresponding circular trajectory movement.

[0047] Furthermore, to ensure the stability of the circular trajectory movement of the pull block 62 during milling, the guide assembly 7 includes a guide disk 8 disposed in the drive cylinder 51 and a limiting assembly 9 mounted on the guide disk 8. The guide disk 8 and the limiting assembly 9 cooperate to limit the circular movement of the pull block 62, preventing the pull block 62 from being displaced outward due to centrifugal force when it rotates with the mounting frame 31, thus preventing the milling cutter from moving outward.

[0048] It is worth noting that when one of the end mills approaches the gear ring, it avoids displacement due to centrifugal force through the guide plate 8 and the limiting component 9, while the other end mill, which is in normal condition, can be located at the end of the slide groove 32 furthest from the gear ring under the action of centrifugal force, and the two end mills will not interfere with each other.

[0049] To improve the stability of the milling cutter when it is normally placed and to prevent unnecessary movement of the unused milling cutter when the mounting bracket 31 rotates, an electromagnetic component 36 is fixedly installed on the mounting bracket 31. The milling bracket 33 is made of magnetic metal. Therefore, when the milling cutter is normally placed, the magnetic force generated by the electromagnetic component 36 can attract and position the milling bracket 33. When the milling bracket 33 needs to be moved, the power can be turned off. The electromagnetic component 36 is an existing component that can generate magnetic force. Its type can be an electromagnetic chuck. It is only necessary to achieve the positioning of the milling bracket 33, which will not be described in detail here.

[0050] Specifically, a positioning rod 66 is fixedly installed on the outside of the pull block 62. The positioning rod 66 is vertically fixed to the pull block 62. The guide plate 8 includes a plate body 81 coaxially disposed inside the drive cylinder 51 and not in contact with the drive cylinder 51, so that the plate body 81 can remain stationary without being affected when the drive cylinder 51 rotates.

[0051] The bottom side of the disc body 81 is provided with a first annular groove 82 and a second annular groove 83 to maintain coaxiality. The first annular groove 82 and the second annular groove 83 are connected by a connecting groove 84. The first annular groove 82 corresponds to the normal position of the pull block 62 when it is not milling, while the second annular groove 82 corresponds to the position of the pull block 62 during milling. Since the mounting bracket 31 will rotate as a whole during milling, it will drive the two pull blocks 62 that are milling and maintaining normal position to rotate synchronously. The first annular groove 82 and the second annular groove 83 can enable the two pull blocks 62 to maintain a stable annular rotation trajectory, thereby improving the stability during milling.

[0052] By adopting the above technical solution, when the mounting bracket 31 rotates, the tops of the two pull blocks 62 can move in a ring along the first annular groove 82 and the second annular groove 83 via the positioning rod 66. In normal operation, the top of the positioning rod 66 is aligned with the length direction of the connecting groove 84 and located at the outer end of the connecting groove 84. After milling, the position of the positioning rod 66 can be aligned with the length direction of the connecting groove 84 and located at the inner end of the connecting groove 84 by controlling the number of rotations of the mounting bracket 31 through the existing milling program. This facilitates the positioning rod 66 to move in or out of the first annular groove 82 and the second annular groove 83 along the connecting groove 84 when the pull block 62 is milled in normal operation or when it is retracted after milling, thus providing stable support for the movement trajectory of the pull block 62.

[0053] The top of the positioning rod 66 is slidably connected to the first annular groove 82, the second annular groove 83 and the connecting groove 84. The outer side of the positioning rod 66 slides in contact with the inner wall of the first annular groove 82, the second annular groove 83 and the connecting groove 84 to improve the stability of the positioning rod 66 when sliding.

[0054] Furthermore, when the positioning rod 66 slides into the second annular groove 83 through the connecting groove 84, the centrifugal force on the positioning rod 66 is high when the mounting bracket 31 rotates, and it may slide outward when passing through the connecting groove 84. Therefore, a limiting groove 811 penetrating both the upper and lower surfaces is provided on the connecting groove 84. The limiting component 9 includes a limiting block 91 that is slidably connected to the limiting groove 811 on the outside and a synchronization plate 92 that is fixedly connected to the outside of the limiting block 91. The synchronization plate 92 is fixedly connected to the piston rod of the second cylinder 94 through the upright 93. The bottom end of the second cylinder 94 is fixedly connected to the disc body 81. The upper and lower ends of the upright 93 are fixed to the second cylinder 94 and the synchronization plate 94, respectively. The second cylinder 94 can drive the synchronization plate 92 to move upward or downward to block the connecting groove 84 or keep its interior unobstructed.

[0055] When not milled, the bottom surface of the limiting block 91 is coplanar with the upper surface of the connecting groove 84, and there are two limiting grooves 811 and two limiting blocks 91. In normal condition, the top of the positioning rod 66 can move smoothly along the connecting groove 84. After the positioning rod 66 moves into the second annular groove 82, the limiting block 91 can move downward through the movement of the synchronous plate 92 to cut off the connecting groove 84. The side of the limiting block 91 near the gear ring is an arc surface coaxial with the inner wall of the second annular groove 83, so that the positioning rod 66 can slide smoothly along its surface to keep the positioning rod 66 rotating stably. After milling is completed, the limiting block 91 is reset.

[0056] The outer side of the disc body 81 is fixedly connected to the first support frame 85 for connection with the external support structure. The bottom end of the first support frame 85 is fixedly connected to the first cylinder 65 through the second support frame 86, so that the two first cylinders 65 can be connected to the external support structure through the second support frame 86. At the same time, the rotation of the drive cylinder 51 will not affect the normal use of the first cylinder 65.

[0057] As one possible implementation method, please refer to Figure 7This technical solution also includes a gear ring processing device for construction machinery. The processing device includes the processing structure described above, and also includes a gear ring A to be processed, an external support mounting structure B, a milling worktable C, an external kinetic energy output structure D, a first type milling cutter E, and a second type milling cutter F. The drive cylinder 51 is rotatably mounted on the external mounting structure B, enabling stable rotation. The clamping assembly 1 is mounted on the milling worktable C, which has an opening for the clamping frame 11 to move. The gear ring A to be processed is placed above the opening and clamped by the clamping frame 11. The external kinetic energy output structure D is a motor, and its output shaft is fixedly connected to the drive gear 53. The external kinetic energy output structure D is fixedly mounted on the external support mounting structure B, which can be a wall or a grounded equipment housing. The first type milling cutter E and the second type milling cutter F can be milling cutters required for gear rings of different thicknesses, or for different types of gear rings (such as normal gear rings or drum-shaped gear rings), or milling cutters required for different milling processes. They can be flexibly combined, and will not be described in detail here.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
