Description

Technical Field

[0001] This utility model belongs to the field of gear processing technology, specifically relating to a gear rolling machine and adjustment mechanism for processing shaft-shaped gears. Background Technology

[0002] A gear rolling machine is a specialized piece of equipment for processing spur gears, helical gears, helical spline gears, oil grooves, tooth grooves, threads, worm gears, and straight grooves on various workpieces. A gear rolling machine that processes tooth grooves on a workpiece includes a bed, a workpiece clamping device mounted on the bed, a gear rolling device, and a drive mechanism that drives the gear rolling mechanism to move.

[0003] Before performing tooth rolling on the outer wall of a shaft-shaped workpiece, it needs to be fixed on a workpiece clamping device. However, the existing workpiece clamping device only serves to hold the outer wall of the workpiece. If the diameter of the workpiece changes, a clamping device of different height needs to be replaced. Otherwise, after the workpiece is pushed into the tooth rolling machine, the axis of the workpiece cannot be collinear with the set machining position axis, which makes it impossible to perform tooth rolling on the outer wall of the workpiece.

[0004] Therefore, a gear rolling machine and adjustment mechanism for machining shaft-shaped gears are designed to solve the technical problem that the single clamping device in the prior art cannot adapt to workpieces of different diameters.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0021] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present.

[0025] Research has revealed that before performing tooth rolling operations on the outer wall of a shaft-shaped workpiece, it needs to be fixed on a workpiece clamping device. However, the existing workpiece clamping device only serves to hold the outer wall of the workpiece. If the diameter of the workpiece changes, it is necessary to replace the clamping device with one of different heights. Otherwise, after the workpiece is pushed into the tooth rolling machine, the axis of the workpiece cannot be collinear with the axis of the set machining position, which makes it impossible to perform tooth rolling operations on the outer wall of the workpiece.

[0026] Based on the above research, this disclosure provides a gear rolling machine and adjustment mechanism for machining shaft-shaped gears. By providing a positioning mechanism and an adjustment mechanism, after the diameter of the shaft-shaped workpiece to be processed is changed, the height of the driving component is adjusted to drive the shaft-shaped workpiece to be processed to move vertically, so that the axis of the shaft-shaped workpiece to be processed is collinear with the axis of the processing position set inside the gear rolling machine. Then, the positioning mechanism is used to push the shaft-shaped workpiece to be processed into the processing position set inside the gear rolling machine for processing, without the need to frequently change clamping devices of different heights to adapt to shaft-shaped workpieces of different diameters.

[0027] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] In some embodiments, such as Figure 1 and Figure 2 As shown, the operator places the shaft-shaped workpiece 3 to be processed on the frame 1, and uses a pair of grippers 45 in the adjustment mechanism 4 to adjust the shaft portion 30 of the shaft-shaped workpiece 3. After adjustment, the processing push cylinder 20 is activated, which controls the push cabinet 21 to slide along the guide direction of the slide rail 24, pushing the shaft-shaped workpiece 3 into the interior of the frame 1. When the shaft-shaped workpiece 3 is in the processing position, the positioning cylinder 22 is activated, and its output end pushes the positioning member 23 to slide along the guide direction of the slide rail 46 until the end of the positioning member 23 abuts against one end of the shaft portion 30 of the shaft-shaped workpiece 3. Figure 1 It can be seen that the positioning mechanism 2 consists of at least two sets, with two positioning parts 23 respectively abutting against the two ends of the shaft portion 30 of the shaft-shaped machining part 3, thereby preventing the shaft-shaped machining part 3 from moving laterally during the subsequent gear rolling operation; In some embodiments, such as Figure 2 and Figure 3 As shown, when the operator inserts the shaft-shaped workpiece 3 between the two grippers 45, the lifting cylinder 400 is activated. Its output end drives the drive shaft 401 to slide within the adjusting base 41, moving synchronously with the drive component 402 fixed at the top of the drive shaft 401. The grippers 45 on both sides of the drive component 402 are preferably made of polyurethane-coated steel core to balance elasticity and rigidity. Initially, the drive component 402 is in a lifted state. The operator inserts the shaft portion 30 of the shaft-shaped workpiece 3 between the two grippers 45. The outer wall of the shaft portion 30 is in contact with the drive component 402. When the diameter of the shaft-shaped workpiece 3 increases, the center of the shaft 30 theoretically moves up by Δh. The lifting cylinder 400 controls the drive component 402 to move down by Δh, so that the center of the shaft 30 returns to the machining axis. The flexible gripper 45 only assists in preventing swaying and does not participate in height positioning. At this time, the two grippers 45 are relatively deflected towards the axis of the shaft 30. The grippers 45 are tightly attached to the outer wall of the shaft 30 to avoid the shaft 30 from shaking due to the inertia generated by the gear part 31 of the shaft-shaped workpiece 3 during rotation during the subsequent gear rolling operation. A support plate 46 is fixed to the lower end face of the lifting cylinder 400, and one end of the support plate 46 is connected to the push cabinet 21 so that when the processing push cylinder 20 is started, the push cabinet 21 can drive the lifting cylinder 400 and the shaft-shaped processing workpiece 3 adjusted by the gripper 45 to move synchronously into the machine frame 1.

[0031] It should be noted that the drive control of the aforementioned processing push cylinder 20, positioning cylinder 22 and lifting cylinder 400 are all existing technologies, and will not be elaborated on here.

[0032] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0034] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0035] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
