Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing gears or racks, in particular to a large gear ring gear manufacturing tool. Background Art

[0002] With the rapid development of the wind power industry, wind power gearboxes are constantly moving towards large megawatt levels. The original equipment is selected for small megawatt gearboxes, and the processing range can no longer meet product requirements, or has reached the equipment limit. Wind power gear rings are mostly processed by milling + grinding. The workbench configured by the equipment manufacturer is small and cannot cover its maximum processing range. Many gear rings cannot be made by themselves and are outsourced, which requires high outsourcing fees, resulting in high production costs. The quotation of wind power gearboxes is greatly affected by this, and it is difficult to obtain orders through low-price bidding, which reduces market competitiveness.

[0003] In order to adapt to the processing of different types of gear rings, the prior art adopts an improved base so that the base can move radially to adjust the clamping radius of the tooling as a whole. For example, publication number: CN105290527B discloses a clamping tooling for milling gears of internal gear rings of wind power generation equipment, including a workbench, the upper end surface of which is provided with a plurality of T-slots extending radially, the T-slots are correspondingly provided with a plurality of bases, and a clamping device is provided on the top of the base. The prior art can satisfy the processing of different types of gear rings by adjusting the base to slide in the T-slot and changing the radial position of the clamping device.

[0004] However, the prior art still has the following technical problems:

[0005] 1. The T-slots of the prior art tend to accumulate a lot of processing waste after processing, which is difficult to clean, hindering radial sliding and reducing work efficiency;

[0006] 2. In order to meet the processing requirements of gear rings of different models, the base is frequently moved for a long time in the prior art, which leads to increased wear of the base, reduced accuracy of the base end face, and reduced production quality of the gear ring;

[0007] 3. The clamping radius of the prior art is still limited by the radius of the workbench, and the clamping radius cannot be effectively extended to the outside of the workbench, resulting in poor versatility of the equipment;

[0008] 4. In order to ensure the structural strength, the prior art sets the locking bolt between the two ribs of the base, which makes it inconvenient to remove the locking bolt and reduces the work efficiency. Utility Model Content

[0009] The utility model provides a large-scale gear ring gear manufacturing tool, which can solve the technical problem of poor universality in the prior art.

[0010] The present application provides the following technical solutions: a large-scale gear ring gear making tool, including a workbench and a supporting structure, the supporting structure is arranged on the workbench, the supporting structure includes a bottom plate and a base, the bottom plate is fixed on the workbench, and the base is fixed on the bottom plate; the bottom plate is a rectangular block, and a plurality of mounting holes are opened in the middle of the bottom plate; the base is I-shaped, and a plurality of locking mounting holes are opened at the bottom of the I-shaped base, and a clamping device and a limiting device are arranged on the base.

[0011] Beneficial effects:

[0012] 1. The base plate and the pedestal are arranged separately. By moving the position of the pedestal on the base plate or further replacing a longer base plate, the radius of the gear ring that can be clamped on the workbench can be effectively expanded or reduced without replacing the workbench, thereby improving the versatility of the equipment. At the same time, because the base plate protrudes from the surface of the processing table, it is easier to clean the waste material processed on the base plate, which can effectively improve the efficiency of the operating equipment in clamping gear rings of different radii. And because the base plate does not need to be moved frequently, the clamping accuracy of the entire tooling can be effectively guaranteed, and the cost of replacing the base plate or the pedestal after wear is also lower.

[0013] 2. The clamping device on the base is used to realize the clamping positioning during the gear ring processing, and the limit device is used to realize the auxiliary positioning before and after the gear ring processing, which can effectively ensure the alignment effect of the gear ring and prevent the gear ring from colliding due to lack of positioning during lifting, resulting in damage to the gear ring or equipment.

[0014] Furthermore, T-shaped grooves are provided in the radial direction of the workbench surface, the upper surface of the bottom plate and the top of the base, and a U-shaped groove is provided on the end of one of the T-shaped grooves on the base.

[0015] Beneficial effects: The T-slot can be used to connect the workbench, the bottom plate and the base, and the U-slot can be used to place the limit support rod.

[0016] Furthermore, T-shaped blocks are arranged on the surface of the workbench, on the bottom plate and in the T-shaped slots on the top of the base.

[0017] Beneficial effect: The T-block is placed in the T-slot, which can be easily fixed with the screw as the bottom plate or the base moves, thereby effectively ensuring that the overall clamping radius of the tooling has good stability after being reduced or expanded.

[0018] Furthermore, the T-block is two rectangular blocks or cylinders stacked up and down, and a threaded hole is opened in the middle of the upper surface of the T-block.

[0019] Beneficial effect: The T-block is set as a rectangular block or a cylinder stacked up and down. The rectangular block can fit the inner wall of the T-slot more closely, and the cylinder can make it easier to align the T-block and install it into the T-slot. The design of two types of T-blocks can meet the needs of different situations and further improve the installation and clamping efficiency of the equipment; the threaded hole in the middle of the upper surface of the T-block can be used to connect the screw.

[0020] Furthermore, the clamping device includes a pressing plate, a locking screw and a limiting support rod, and the limiting support rod is detachably supported between the pressing plate and the base; a strip groove is opened on the pressing plate, and the locking screw is passed through the strip groove, and the bottom of the locking screw is fixedly connected to the T-block in the T-slot at the top of the base.

[0021] Beneficial effects: The limit support rod can be used to limit the pressing height of the pressure plate to prevent the pressure plate from over-pressing and damaging the surface of the gear ring, and limit support rods of different heights can be equipped according to the needs of different gear rings. When replacing parts, the limit support rod can be placed in the U-shaped groove for easy picking; a strip groove is provided on the pressure plate, and the locking screw is passed through the strip groove, which can facilitate the adjustment of the position of the pressure plate and prevent the pressure plate and the gear ring from colliding when replacing the gear ring. When tightening the gear ring, it is easier to adjust to a better clamping position to ensure a better clamping effect; the locking screw is fixedly connected to the T-block in the T-slot on the top of the base, so that the position of the base on the bottom plate can be adjusted as needed, thereby effectively expanding or reducing the clamping radius of the tooling.

[0022] Furthermore, the limiting device includes a limiting screw, which is fixedly connected to a T-block in a T-slot on the top of the base.

[0023] Beneficial effects: The limit screw can be used to roughly position the gear ring, and at the same time prevent the gear ring from shaking violently during lifting and knocking down the clamping device to damage the guide rail accuracy. It can further ensure that the position of the gear ring is fixed when placed on the base, which is convenient for the clamping device to clamp. The limit screw is fixedly connected to the T-block in the T-slot on the top of the base so that the position of the limit screw in the T-slot can be adjusted as needed, so as to roughly position gear rings of different radii.

[0024] Furthermore, the limiting screw includes a top, a middle and a bottom. The top of the limiting screw is set as a hexagonal stud, the middle of the limiting screw is set as a cylinder, and the bottom of the limiting screw is set as a threaded column. The diameter of the threaded column is smaller than the diameter of the cylinder.

[0025] Beneficial effects: The top of the limit screw is set as a hexagonal stud, which can facilitate the loosening or tightening of the limit screw to adjust its position. The middle part of the limit screw is set as a cylinder and the diameter of the cylinder is larger than the diameter of the bottom threaded column. It can ensure that the cylindrical surface contacts the gear ring when the limit screw performs rough positioning on the gear ring, and it can ensure that the limit screw is easy to disassemble after the gear ring is installed.

[0026] Furthermore, there is one T-slot on the top of the base, and the T-slot is arranged obliquely, and two T-blocks are arranged in the T-slot; and a placement hole is opened on the top of the base.

[0027] Beneficial effects: a T-slot is provided on the top of the base and is tilted, so that the positions of the limiting device and the clamping device are not on the same horizontal line, that is, the limiting device can always be located in front of the clamping device, thereby ensuring that the gear ring is roughly positioned by the limiting device and then clamped by the clamping device; the two T-blocks in the T-slot can be used to install the limiting device and the clamping device; the placement hole on the top of the base is used to replace the U-slot to place the limiting support rod.

[0028] Furthermore, there is one T-slot on the top of the base, and the edge of the T-slot is parallel to the side of the base; the limiting device also includes an L-shaped positioning block, and the L-shaped positioning block is arranged between the limiting screw and the T-block.

[0029] Beneficial effect: A T-shaped slot is arranged on the top of the base, and the side of the T-shaped slot is parallel to the side of the base, and the limiting device also includes an L-shaped positioning block. This arrangement can make the L-shaped positioning block and the pressing plate of the clamping device on the same horizontal line, making it easier to adjust the relative position of the clamping device and the limiting device, and improving the efficiency of limiting and clamping.

[0042] The marks in the drawings in the specification include: workbench 1, gear ring 2, bottom plate 3, base 4, locking mounting hole 41, U-shaped slot 42, placement hole 43, T-shaped slot 5, T-block 6, clamping device 7, pressure plate 71, strip slot 711, locking screw 72, limiting support rod 73, limiting device 8, limiting screw 81, hexagonal stud 811, cylinder 812, threaded column 813, L-shaped positioning block 82.

[0043] Embodiment 1

[0045] The supporting structure includes a bottom plate 3 and a base 4. The bottom plate 3 is fixed on the workbench 1, and the base 4 is fixed on the bottom plate 3. Specifically, the bottom plate 3 is a rectangular block, and a plurality of mounting holes and a lifting hole are opened in the middle of the bottom plate 3. A plurality of T-slots 5 are opened on the upper surface of the bottom plate 3. Specifically, in this embodiment, four mounting holes are opened in the middle of the bottom plate 3 (for inserting screws into the T-slots 5 of the workbench, and the screws cooperate with the T-blocks 6 set in the T-slots 5 to fix the bottom plate 3 on the workbench 1), and a lifting hole is opened between the mounting holes (for lifting The bottom plate 3 has a T-slot 5 (for connecting the base 4) on both sides of the mounting hole, and further, the bottom plate 3 can be designed according to different gear ring diameters. For example, when the diameter of the gear ring to be clamped is larger, the length of the bottom plate is set longer according to the diameter of the gear ring, so that after the bottom plate 3 is installed on the workbench 1, the stroke of the base 4 on the bottom plate becomes longer, thereby effectively expanding the clamping radius of the tooling as a whole; conversely, when the diameter of the gear ring to be clamped is smaller, the length of the bottom plate 3 can be shortened, thereby reducing the clamping radius of the tooling.

[0046] The base 4 is I-shaped, with a plurality of locking mounting holes 41 at the bottom of the I-shaped base 4, a plurality of T-slots 5 at the top of the base 4, and a clamping device 7 and a limiting device 8 installed on the T-slots 5. Specifically, in this embodiment, a locking mounting hole 41 is respectively provided on both sides of the bottom of the I-shaped base 4, and the position of the locking mounting hole 41 corresponds to the position of the T-slot 5 on the bottom plate 3, so that the screw passing through the locking mounting hole 41 can extend into the T-slot 5 on the upper surface of the bottom plate 3, and cooperate with the T-block 6 provided in the T-slot 5 to achieve locking and fixing the base 4 on the bottom plate 3. Further, in this embodiment, two T-slots 5 are provided in parallel on the base 4, and a U-slot 42 is provided at the end of one T-slot 5.

[0047] The clamping device 7 includes a clamping plate 71, a locking screw 72 and a limiting support rod 73. The limiting support rod 73 is detachably supported between the clamping plate 71 and the base 4. A strip groove 711 is provided on the clamping plate 71. The locking screw 72 is inserted into the strip groove 711. The bottom of the locking screw 72 is fixedly connected to the T-block 6 in the T-slot 5 at the top of the base 4. In this embodiment, the limiting support rod 73 is a cylinder 812, and the size of the cylinder 812 matches the U-slot 42, so that the limiting support rod 73 can be placed in the U-slot 42 when replacing parts, which is convenient for storage and taking; the clamping plate 71 is a strip block, which is used to cooperate with the locking screw 72 for clamping.

[0048] The limiting device 8 includes a limiting screw 81, and the limiting screw 81 is fixedly connected to the T-block 6 in the T-slot 5 at the top of the base 4. Specifically, in this embodiment, Fig.11As shown, the limiting screw 81 includes a top, a middle and a bottom. The top of the limiting screw 81 is set as a hexagonal stud 811, the middle of the limiting screw 81 is set as a cylinder 812, and the bottom of the limiting screw 81 is set as a threaded column 813. The diameter of the threaded column 813 is smaller than the diameter of the cylinder 812.

[0049] like Figure 8-10 As shown, the T-block 6 is two rectangular blocks or cylinders 812 stacked up and down, and a threaded hole is opened in the middle of the upper surface of the T-block 6. Specifically, the T-block 6 can be two rectangular blocks and cylinders 812 stacked together, or two rectangular blocks stacked together, or two cylinders stacked together 812. In this example, the T-block 6 can be two rectangular blocks stacked together, and a threaded hole is opened on the top of the T-block 6 for locking with a screw.

[0050] Here’s how to use it:

[0051] 1) Adjust the clamping radius. Select an appropriate base plate 3 and install it on the processing table as needed, such as Figure 1 As shown, when the radius of the gear ring 2 to be clamped is smaller than the radius of the processing table, a shorter bottom plate 3 can be selected, and the base 4 can be adjusted to a suitable position and fixed on the bottom plate 3.

[0052] 2) Rough positioning: The limiting screw 81 is pre-arranged in the T-slot 5 to roughly position the gear ring 2 hoisted and placed on the base 4 .

[0053] 3) Pressing and positioning. After the gear ring 2 is placed on the base 4, it is adjusted so that the gear ring 2 is in a suitable position and can be processed. The locking nut, the pressing plate 71 and the limiting support rod 73 cooperate to press the gear ring 2 into position.

[0054] 4) After processing, hoist and roughly position.

[0055] Embodiment 2

[0056] like Figure 4 , Figure 5 As shown, the difference between this embodiment and the first embodiment is that there is only one T-slot 5 on the top of the base 4, and the T-slot 5 is set at an angle, and two T-blocks 6 are arranged in the T-slot 5; a placement hole 43 is opened on the top of the base 4, the U-slot 42 is cancelled, and an annular protrusion is arranged around the limiting support rod 73.

[0057] In this embodiment, the inclined T-slot 5 is used to facilitate the quick positioning of the limiting screw 81 in front of the clamping device 7, thereby facilitating the improvement of the efficiency of rough positioning. In this embodiment, an additional placement hole 43 is provided and the U-slot 42 is eliminated, so that the limiting support rod 73 with the annular protrusion is easier to store and can effectively prevent the limiting support rod 73 from falling.

[0058] Embodiment 3

[0059] like Figure 6 , Figure 7 As shown, the difference between this embodiment and the second embodiment is that there is only one T-slot 5 on the top of the base 4, and the side of the T-slot 5 is parallel to the side of the base 4; the limiting device 8 also includes an L-shaped positioning block 82, and the L-shaped positioning block 82 is arranged between the limiting screw 81 and the T-block 6, and the limiting screw 81 is arranged as an ordinary screw, which is only used to fix the L-shaped positioning block 82.

[0060] In this embodiment, the side of the T-slot 5 is parallel to the side of the base 4, and an L-shaped positioning block 82 is additionally provided.
