Description

Technical Field

[0001] The present invention relates to the technical field of gear profile modification, and particularly relates to an adjustable support mechanism for gear tooth surface modification. Background Art

[0002] Gear tooth surface modification refers to the process of micro-adjusting the gear tooth surface, aiming to optimize the performance of the gear, improve its transmission accuracy, strength and service life, and at the same time reduce noise and temperature rise.

[0003] Currently, a support and clamping structure is generally used for gear tooth surface modification. However, the current support and clamping mechanism generally uses a fixture, which is generally composed of two clamping plates. Such a clamping method is relatively troublesome. Generally, a screw needs to be rotated to drive the clamping plates to approach and open. Its adaptability is poor, and it is easy to block one side of the gear, and the gear needs to be rotated and positioned subsequently, thus affecting the modification efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an adjustable support mechanism for gear tooth surface modification, which can be directly sleeved on a cylinder, and the cylinder that descends can quickly complete the positioning of the gear to be modified, and can adapt to gears to be modified with different inner holes, so as to solve the problems raised in the above background art.

[0005] The present invention is realized through the following technical solutions: An adjustable support mechanism for gear tooth surface modification, including a gear to be modified, a placement seat and a cylinder. The gear to be modified is placed on the placement seat. A cylinder is installed in the placement seat. The cylinder passes through the central hole of the gear to be modified and is fixedly connected to the piston rod of the cylinder. A vertical channel is axially provided inside the cylinder. One end of the cylinder is provided with a plurality of installation grooves communicated with the vertical channel. Extrusion blocks are movably installed in the installation grooves. The inner circles of the extrusion blocks are all inclined to form a flow guiding part, and the flow guiding parts all protrude and extend into the vertical channel. An extrusion column for pushing the extrusion blocks outwards is arranged inside the vertical channel.

[0006] As a preferred technical solution, one end of the placement seat is provided with a fixed groove, and the other end is provided with a through hole communicated with the fixed groove. The outer shell of the cylinder is arranged in the fixed groove. The piston rod of the cylinder passes through the through hole and is fixedly connected to the cylinder.

[0007] A guiding channel is provided on the bottom surface of any one of the installation grooves. A connecting block is installed on the outer circumferential surface of the extrusion column opposite to the guiding channel. One end of the connecting block passes through the guiding channel and is installed on the inner wall surface of the through hole.

[0008] As a preferred technical solution, an internal thread is provided on the inner circumferential surface of the fixing groove opening. A fixing ring is installed outside the housing of the air cylinder. An external thread is provided on the outer circumferential surface of the fixing ring. The fixing ring is engaged and connected with the internal thread on the fixing groove through the external thread. A plurality of slots are provided at one end of the fixing ring away from the through hole.

[0009] As a preferred technical solution, a fixing plate is installed on one side of the placing seat, and a plurality of fixing holes are provided on the fixing plate.

[0010] As a preferred technical solution, shaft holes are provided on both sides of the installation groove. Shaft rods are installed at one end of each extrusion block.

The other ends of the torsion springs are installed on the inner wall surface of the installation holes.

[0011] As a preferred technical solution, the outer side surfaces of the extrusion blocks are flush with the outer circumferential surface of the column body.

[0012] As a preferred technical solution, the diameter of the placing seat is smaller than the diameter of the gear to be shaped.

[0013] As a preferred technical solution, one end of each extrusion block facing the placing seat is inwardly tapered, and a space for the extrusion block to rotate outward is formed between the lower part of the extrusion block and the installation groove.

[0014] As a preferred technical solution, both the column body and the extrusion blocks are made of metal materials.

[0015] The beneficial effects of the present invention are as follows: The structure of the present invention is simple. The gear to be shaped can be sleeved outside the column body and placed on the placing seat. The column body can automatically descend through the air cylinder. During the descending process, the extrusion blocks can be automatically opened, so that multiple extrusion blocks are distributed in a conical structure. Through the opened extrusion blocks, the gear to be shaped can be centered and sleeved on the column body, and the gear to be shaped with different apertures can be pressed downward.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0025] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0027] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, an adjustable support mechanism for gear tooth surface modification according to the present invention includes a gear 1 to be modified, a placement seat 2, and a cylinder 4. The gear 1 to be modified is placed on the placement seat 2. A cylinder 8 is installed in the placement seat 2. The cylinder 4 passes through the central hole of the gear 1 to be modified and is fixedly connected to the piston rod of the cylinder 8. A vertical channel is axially provided inside the cylinder 4. One end of the cylinder 4 is provided with a plurality of installation grooves 5 communicating with the vertical channel. Extrusion blocks 6 are movably installed in the installation grooves 5. The inner circles of the extrusion blocks 6 are inclined to form a diversion part, and the diversion parts all protrude and extend into the vertical channel. An extrusion column 11 for pushing the extrusion blocks 6 outwards is arranged inside the vertical channel.

[0028] In this embodiment, one end of the placement seat 2 is provided with a fixing groove 14, and the other end is provided with a through hole 15 communicating with the fixing groove 14. The outer shell of the cylinder 8 is arranged in the fixing groove 14. The piston rod of the cylinder 8 passes through the through hole 15 and is fixedly connected to the cylinder 4.

[0029] A guiding channel 7 is provided on the bottom surface of any one of the installation grooves 5. A connecting block 12 is installed on the outer circumferential surface of the extrusion column 11 facing the guiding channel 7. One end of the connecting block 12 passes through the guiding channel 7 and is installed on the inner wall surface of the through hole 15.

[0030] In this embodiment, an internal thread is provided on the inner circumferential surface of the opening of the fixing groove 14. A fixing ring 9 is installed outside the outer shell of the cylinder 8. An external thread is provided on the outer circumferential surface of the fixing ring 9. The fixing ring 9 is meshed and connected to the internal thread on the fixing groove 14 through the external thread. A plurality of slots 10 are provided at one end of the fixing ring 9 away from the through hole 15.

[0031] In this embodiment, a fixing plate 3 is installed on one side of the placement seat 2. A plurality of fixing holes are provided on the fixing plate 3. Among them, bolts can pass through the fixing holes to fix the fixing plate at the edge of any platform. The opening of the installation groove is arranged outside the platform, so that the lower part of the opening of the installation groove is not blocked. After inserting any rod into the slot, the fixing ring can be rotated so that the fixing ring can be disengaged from the fixing groove. At this time, the cylinder and the cylinder can be directly taken out downward along the fixing groove, which greatly facilitates subsequent cleaning, maintenance, and replacement.

[0032] In this embodiment, shaft holes are provided on both sides of the installation groove 5. One end of each extrusion block 6 is installed with a shaft rod 13. Both ends of the shaft rod 13 are inserted into the shaft holes and are both installed with torsion springs. The other ends of the torsion springs are both installed on the inner wall surface of the installation hole.

[0033] In this embodiment, the outer side surfaces of the extrusion blocks 6 are flush with the outer circumferential surface of the cylinder 4, so that the outer circumferential surfaces of the extrusion blocks and the cylinder are flush. When the gear to be modified is sleeved, it can pass through the extrusion blocks more efficiently.

[0034] In this embodiment, the diameter of the placement seat 2 is smaller than that of the gear to be shaped 1, so that the outer ring of the gear to be shaped is not blocked, enabling the gear shaping operation to be carried out without obstruction at 360°.

[0035] In this embodiment, one ends of the extrusion blocks 6 facing the placement seat 2 are all arranged to shrink inwards. Spaces for the extrusion blocks 6 to rotate outwards are formed between the lower sides of the extrusion blocks 6 and the installation grooves 5, enabling the extrusion blocks to open outwards with the shaft rod as the center, avoiding being blocked by the installation grooves and affecting the opening degree.

[0036] In this embodiment, both the column body 4 and the extrusion blocks 6 are made of metal materials, increasing firmness, being able to better press the gear to be shaped, and also ensuring the service life.

[0037] During use, the gear to be shaped can be directly sleeved on the main body and placed on the placement seat. After the sleeving is completed, the air cylinder can be started to retract the piston rod of the air cylinder. The retraction of the piston rod drives the column body. As the column body descends, the extrusion column can squeeze with the diversion part, causing the extrusion blocks to open outwards with the shaft rod as the center, making multiple extrusion blocks distributed in a conical structure. After opening, when the column body continues to move downwards, the outer side surfaces of the extrusion blocks will squeeze with the end face of the central hole on the gear to be shaped. Through the opened extrusion blocks, the gear to be shaped can be centered and sleeved on the column body, and different-diameter gears to be shaped can be pressed downwards to ensure the stability of the gear during the shaping process.

[0038] After the shaping is completed, the air cylinder can be started again to extend the piston rod of the air cylinder. The movement of the piston rod pushes the column body. As the column body ascends, the positioning column will move out from between the extrusion blocks. After losing the blockage of the positioning column, the shaft rod and the extrusion blocks can be automatically rotated through the torsion of the torsion spring, causing the extrusion blocks to return to their positions again and be flush with the outer circumferential surface of the column body. At this time, the gear to be shaped can be directly taken off upwards from the column body, greatly increasing the overall operation efficiency.

[0039] As described above, the above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
