Description

TECHNICAL FIELD

[0001] The utility model belongs to mechanical device technical field relates to chain saw device especially is a kind of ball mounting assembly of chain saw guide wheel installation machine. BACKGROUND

[0002] The ball mounting assembly of chain saw guide wheel installation machine is a mechanism for producing chain saw guide wheels, which is one of the components of chain saws. The ball is one of the components of chain saw guide wheels. The chain saw guide wheel is usually located at the outer end of the chain saw guide plate and is usually circular. It has a groove on the outside to fit the chain link, and a ball is arranged inside to rotate smoothly. It supports and guides the smooth operation of the chain, ensuring cutting efficiency and safety.

[0003] In the prior art, manual feeding of the ball and pre-positioning before assembly are usually used. The overall production efficiency is low, and faults are prone to occur, resulting in low yield. On the other hand, in the production process, multiple processes rely on manual operation, resulting in high production cost and the risk of accidents. SUMMARY

[0004] The utility model aims at the above problem, provide a kind of automatic ball mounting assembly of chain saw guide wheel installation machine.

[0005] To achieve the above object, the utility model adopts the following technical scheme: the ball mounting assembly of chain saw guide wheel installation machine, including rack, the rack is equipped with through-hole, and the through-hole is equipped with the fixed setting and does not contact the through-hole round piece support column, is equipped with ball jacking sleeve between round piece support column and through-hole, and the bottom of ball jacking sleeve is equipped with ball jacking drive mechanism.

[0006] By setting ball jacking drive mechanism to drive ball jacking sleeve, the automatic assembly of ball in the corresponding position of ball jacking sleeve in through-hole can be realized.

[0007] In the ball mounting assembly of chain saw guide wheel installation machine described above, the ball jacking drive mechanism includes a jacking lifting seat connected to the bottom of the ball jacking sleeve, and the round piece support column passes through the jacking lifting seat. A lifting guide assembly and a lifting drive assembly are arranged between the jacking lifting seat and the rack. The setting of the guide assembly can ensure that the jacking lifting seat moves strictly in the vertical direction, avoiding assembly errors caused by deviation.

[0008] In the ball mounting assembly of the chain saw guide wheel mounting machine, the lifting guide assembly comprises a support, a through hole is formed in the gear support plate of the frame, a lifting hole is formed in the bottom plate of the frame at the bottom of the through hole, the support is arranged at the bottom of the lifting hole, and at least two circumferentially distributed guide rods are arranged between the support and the jacking lifting seat. The at least two circumferentially distributed guide rods rigidly constrain the vertical movement of the jacking lifting seat from multiple directions. The jacking lifting seat is prevented from tilting or being stuck, and the axis of the ball jacking sleeve is always strictly aligned with the disc support column.

[0009] In the ball mounting assembly of the chain saw guide wheel mounting machine, the lifting drive assembly comprises a cam connected to the support in sliding mode, an inclined surface is arranged on the upper surface of the cam and inclined to the bottom surface of the support, at least one roller connected to the inclined surface in sliding mode is arranged on the inclined surface, the roller is connected to the jacking lifting seat through a roller seat, and the cam is connected to a linear driver capable of driving the cam to move laterally and thereby drive the roller to lift. The lateral linear movement of the lifting linear driver is directly converted into the vertical lifting movement of the jacking lifting seat through the rolling contact between the inclined surface of the cam and the roller. Rolling friction replaces traditional sliding friction, which can prolong the service life of the mechanism.

[0010] In the ball mounting assembly of the chain saw guide wheel mounting machine, a sliding block sliding rail unit is arranged between the support and the cam. The sliding block sliding rail unit accurately guides the lateral movement of the cam, eliminates the influence of lateral deviation on the lifting trajectory, and can ensure the stability of the lifting action.

[0011] In the ball mounting assembly of the chain saw guide wheel mounting machine, a rotating drive mechanism capable of driving the ball jacking sleeve to rotate is arranged between the ball jacking sleeve and the jacking lifting seat. Arranging the rotating drive mechanism between the ball jacking sleeve and the jacking lifting seat allows the ball jacking sleeve to rotate independently during lifting, ensuring the coordinated execution of lifting and rotating actions.

[0012] In the ball mounting assembly of the chain saw guide wheel mounting machine, the rotating drive mechanism comprises a driven gear fixed to the outer wall of the lower end of the ball jacking sleeve, a thrust bearing is arranged between the ball jacking sleeve and the jacking lifting seat, the driven gear is connected to a driving gear, and the driving gear is connected to a rotating driver. The design of the meshing transmission between the driven gear and the driving gear provides high-precision and high-rigidity power transmission, which can accurately control the rotation angle of the ball jacking sleeve and meet the demand for angle positioning in precise assembly. Moreover, through the arrangement of the thrust bearing, the thrust bearing bears the axial load and isolates the rotation freedom, avoiding mutual interference between the two movements, and ensuring independent control of the lifting and rotating actions.

[0013] In the ball mounting assembly of the chain saw guide wheel mounting machine, the driven gear is connected with the ball jacking sleeve through the bearing guide sleeve, the lower end of the driven gear abuts against the convex ring of the bearing guide sleeve and is fixed through a plurality of bolts, the lower end of the ball jacking sleeve is sleeved on the bearing guide sleeve and is fixed through a plurality of radial bolts, the linear bearing is arranged between the bearing guide sleeve and the round piece supporting column, and the thrust bearing is arranged between the bearing guide sleeve and the bearing step of the jacking lifting seat. The ball jacking sleeve and the bearing guide sleeve are fixed through radial bolts, bidirectional constraint is formed, and circumferential sliding can be prevented. In addition, the thrust bearing is arranged between the bearing guide sleeve and the bearing step of the jacking lifting seat, and the service life of the mechanism is prolonged.

[0014] In the ball mounting assembly of the chain saw guide wheel mounting machine, the side wall of the through hole is provided with a ball feeding groove capable of being connected with a ball feeding mechanism. The ball feeding groove connected with the ball feeding mechanism can avoid the deviation of the ball during feeding, thereby avoiding the poor assembly effect caused by the position deviation.

[0015] In the ball mounting assembly of the chain saw guide wheel mounting machine, the round piece supporting column comprises an upper top head and a supporting rod, and the lower end of the supporting rod is detachably fixed with the support. The upper top head with a larger area arranged at the top of the supporting rod can ensure the stability of support, the thin supporting rod can save installation space, and the structure is more compact.

[0016] Compared with the prior art, the ball mounting assembly of the chain saw guide wheel mounting machine has the advantages that: 1. a plurality of driving structures are cooperatively controlled to realize automatic assembly; 2. the ball feeding mechanism and the driving mechanism are linked and controlled to cooperatively work, and the assembly efficiency is high; and 3. the demand for manual operation is low, the risk of manual contact is reduced, and the probability of accidents is low.
