Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to an oiling and lubricating mechanism with a screw gear. Background Art

[0002] The combination of screw and gear is a common transmission mechanism in machinery and is widely used in the automotive field. When processing incoming materials, the gear and screw are usually meshed and assembled as a whole component (hereinafter referred to as "gear with screw") for circulation assembly at different stations. Lubricating oil needs to be added to the meshing surface of the gear with screw before leaving the factory to enhance its transmission effect. Since part of the gear meshing surface of the gear with screw is blocked by the screw, and the existing refueling mechanism lacks an effective separation structure, it is difficult to refuel the blocked gear meshing surface. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a lubrication mechanism with a screw gear, which can separate the gear and the screw through mechanical cooperation to perform lubrication operation on the gear meshing surface.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a refueling and lubricating mechanism with a screw gear is arranged on the refueling station of the assembly conveyor line, and the assembly conveyor line is provided with at least one tray that can be moved to the refueling station along its conveying direction, and the tray is placed with a screw gear; the refueling and lubricating mechanism includes

[0005] A refueling assembly, arranged on one side of the refueling station, for spraying lubricating oil;

[0006] A material moving assembly is located above the assembly conveyor line and comprises a material moving base, on which a sliding base plate capable of reciprocating between a tray and a refueling assembly is provided;

[0007] A material taking component is arranged on the sliding base plate, and includes a gear clamping part and a screw clamping part which can be synchronously lifted and lowered under the action of the lifting driving part, and the gear clamping part and the screw clamping part can respectively clamp the gear with the screw gear and the screw;

[0008] The separation component is arranged on the material taking component and is used to drive the screw clamping part to move horizontally relative to the gear clamping part so as to separate the screw clamped on the screw clamping part from the gear clamped on the gear clamping part.

[0009] The beneficial effects of the oiling and lubricating mechanism of the utility model are:

[0010] The gear clamping part and the screw clamping part in the material picking component can clamp the gear and the screw with the screw gear respectively; then the meshing gear and the screw can be separated by the separation component arranged on the material picking component. At this time, the gear clamping part and the screw clamping part still clamp the gear and the screw respectively; then the material picking component is moved to the working area of ​​the refueling component through the material moving component. Due to the separation of the gear and the screw, the meshing surface of the gear can be completely exposed, so as to facilitate the refueling operation of the refueling component on the meshing surface of the gear.

[0011] Furthermore, the material picking assembly includes a material picking base plate that can be lifted and moved under the action of the lifting drive unit, and the separation assembly includes a separation plate that is slidably arranged on the material picking base plate in a direction perpendicular to the assembly conveyor line, and the screw clamping portion is provided at one end of the separation plate facing the gear clamping portion.

[0012] In actual application, the gear with screw is placed on the tray through a fixture, and its screw and gear are roughly arranged in the horizontal direction; when the gear clamping part and the screw clamping part clamp the gear and screw in the fixture, the lifting drive part can drive the gear clamping part and the screw clamping part to rise, and the gear and screw rise immediately. At this time, the gear and screw are still arranged in the horizontal direction; then the screw clamping part is moved horizontally away from the gear clamping part through the horizontal movement of the separation plate to separate the screw from the gear. Since the gear meshing surface is usually helical teeth, vertical separation is prone to cause helical teeth wear. Therefore, this application limits the separation action to be performed in the horizontal direction.

[0013] Furthermore, the screw clamping part includes a screw pneumatic clamping claw that can move toward or away from the screw under the action of the in-position drive. When the gear clamping part and the screw clamping part are synchronously lowered under the action of the lifting drive, the gear clamping part can first clamp the gear with the screw gear; then the lifting drive stops driving, and the screw pneumatic clamping claw moves to the position with the screw gear under the action of the in-position drive and clamps the screw with the screw gear.

[0014] Furthermore, the positioning drive member includes a positioning cylinder arranged on the separation plate along an inclined direction, and the positioning cylinder can drive the screw pneumatic clamp to move along the inclined direction. The positioning cylinder is limited to being arranged along the inclined direction, which can avoid the lifting movement of the lifting drive part and make the structure of the material taking component more compact.

[0015] Specifically, the gear clamping part includes a clamping base plate, a rotating driving member, and a gear pneumatic clamping jaw. The clamping base plate is fixedly connected to the material taking base plate. The rotating driving member is installed on the clamping base plate to drive the gear pneumatic clamping jaw to rotate. The gear pneumatic clamping jaw is used to clamp the gear with the screw gear. The setting of the rotating driving member can drive the gear located on the gear pneumatic clamping jaw to rotate, so that the meshing surface of the gear can be fully sprayed by the oiling assembly during the rotation process.

[0016] Furthermore, the material transfer base is provided with a linear module and a guide rail arranged in parallel, and the linear module and the guide rail are arranged in a horizontal direction; the sliding base plate is connected to the linear module and is slidably arranged on the guide rail through a connecting seat. The setting of the guide rail makes the movement of the sliding base plate more stable.

[0017] Furthermore, the refueling station is provided with a lifting assembly for lifting the pallet, and the lifting assembly includes a lifting plate that can be lifted and lowered under the action of a lifting drive; when the lifting plate rises, the lifting plate can support the pallet at the refueling station and make the pallet separate from the assembly conveyor line. The setting of the lifting assembly allows the pallet to stay at the refueling station, so as to facilitate the refueling operation of the screw gear on the pallet.

[0018] Furthermore, a stop assembly is also provided at the refueling station, and the stop assembly includes stop plates symmetrically arranged on both sides of the assembly conveyor line, and the stop plates can abut against the upper end surface of the pallet to limit the staying height of the pallet at the refueling station.

[0019] Furthermore, the refueling assembly includes a refueling rack mounted on the assembly conveyor line, and the refueling rack is provided with a refueling gun arranged toward the pallet. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0038] Example

[0039] See attached Figure 1-3 As shown, a refueling and lubricating mechanism with a screw gear of the utility model is arranged at a refueling station of an assembly conveyor line 1. The assembly conveyor line 1 is provided with at least one tray 2 that can be moved to the refueling station along its conveying direction, and a screw gear 3 is placed on the tray 2. The refueling and lubricating mechanism includes a refueling assembly 4, a material moving assembly 5, a material taking assembly 6, and a separation assembly 7, wherein the refueling assembly 4 is arranged at one side of the refueling station to spray lubricating oil on the meshing surface of the gear. The material moving assembly 5 is located above the assembly conveyor line 1, and includes a material moving base 51, on which a sliding base plate 52 that can reciprocate between the tray 2 and the refueling assembly 4 is provided.

[0040] The material taking component 6 is arranged on the sliding base plate 52, and includes a gear clamping part 62 and a screw clamping part 63 which can be synchronously lifted and lowered under the action of the lifting driving part 61, and the gear clamping part 62 and the screw clamping part 63 can respectively clamp the gear 31 and the screw 32 with the screw gear 3. The separation component 7 is arranged on the material taking component 6, and is used to drive the screw clamping part 63 to move horizontally relative to the gear clamping part 62, so that the screw 32 clamped on the screw clamping part 63 is separated from the gear 31 clamped on the gear clamping part 62.

[0041] When the tray 2 with the screw gear 3 is placed moves to the refueling station, the sliding base plate 52 moves close to the tray 2, and the lifting drive unit 61 immediately drives the gear clamping unit 62 and the screw clamping unit 63 to descend, and the gear clamping unit 62 and the screw clamping unit 63 immediately clamp the gear 31 and the screw 32 with the screw gear 3; then the lifting drive unit 61 drives the gear clamping unit 62 and the screw clamping unit 63 to rise, and the screw gear 3 immediately rises under the action of the gear clamping unit 62 and the screw clamping unit 63; the separation component 7 drives the screw clamping unit 63 to move horizontally relative to the gear clamping unit 62, so that the screw 32 with the screw gear 3 , gear 31 is separated; then the sliding base plate 52 moves to the vicinity of the refueling assembly 4, and the material taking assembly 6 immediately drives the separated gear 31 and screw 32 to move synchronously to the refueling assembly 4. At this time, the meshing surface of the gear 31 is completely exposed, and the refueling assembly 4 immediately performs a refueling operation on the gear 31; when the refueling operation is completed, the separation assembly 7 is started to make the screw clamping part 63 move horizontally in the opposite direction relative to the gear clamping part 62, and the screw 32 meshes with the gear 31 again to form a gear 3 with a screw; then the material taking assembly 6 and the sliding base plate 52 cooperate to place the gear 3 with a screw after refueling on the tray 2.

[0042] The gear clamping part 62 and the screw clamping part 63 in the material picking component 6 can respectively clamp the gear 31 and the screw 32 with the screw gear 3; then the separation component 7 arranged on the material picking component 6 can separate the meshing gear 31 and the screw 32. At this time, the gear clamping part 62 and the screw clamping part 63 still clamp the gear 31 and the screw 32 respectively; then the material picking component 6 is moved to the working area of ​​the refueling component 4 through the material moving component 5. Due to the separation of the gear 31 and the screw 32, the meshing surface of the gear 31 can be completely exposed, so as to facilitate the refueling operation of the refueling component 4 on the gear meshing surface.

[0043] In actual application, the gear 3 with screw is placed on the tray 2 through a fixture, and its screw 32 and gear 31 are roughly arranged in the horizontal direction; when the gear clamping part 62 and the screw clamping part 63 clamp the gear 31 and the screw 32 in the fixture, the lifting drive part 61 can drive the gear clamping part 62 and the screw clamping part 63 to rise, and the gear 31 and the screw 32 will rise immediately. At this time, the gear 31 and the screw 32 are still arranged in the horizontal direction; then the screw clamping part 63 is moved horizontally away from the gear clamping part 62 through the horizontal movement of the separation component 7, so as to separate the screw 32 from the gear 31. Since the gear meshing surface is usually helical teeth, vertical separation is prone to cause wear of the helical teeth. Therefore, the present application limits the separation action to be performed in the horizontal direction. Specifically, in some embodiments, see the attached Figure 4 As shown, the material picking component 6 includes a material picking substrate 64 that can be lifted and moved under the action of a lifting drive unit 61, and the separation component 7 includes a separation plate 71 slidably arranged on the material picking substrate 64 in a direction perpendicular to the assembly conveyor line 1, and a screw clamping portion 63 is provided at one end of the separation plate 71 facing the gear clamping portion 62.

[0044] The screw rod clamping part 63 includes a screw rod pneumatic clamping jaw 632 that can move toward or away from the screw rod 32 under the action of the in-position driving member 631. When the gear clamping part 62 and the screw rod clamping part 63 are synchronously lowered under the action of the lifting driving part 61, the gear clamping part 62 can first clamp the gear 31 with the screw rod gear 3; then the lifting driving part 61 stops driving, and the screw rod pneumatic clamping jaw 632 moves to the position with the screw rod gear 3 under the action of the in-position driving member 631 and clamps the screw rod 32 with the screw rod gear 3.

[0045] The reason why the screw clamping part 63 is driven to move by the in-position drive 631 alone is that after the screw 32 and the gear 31 are meshed and assembled, there is a certain height difference between the two. When the lifting drive 61 drives the screw clamping part 63 and the gear clamping part 62 to descend synchronously, it is possible that the screw clamping part 63 and the gear clamping part 62 cannot move to the screw 32 and the gear 31 respectively at the same time, resulting in the risk that the screw clamping part 63 (or the gear clamping part 62) cannot clamp the screw 32 (or the gear 31). Therefore, in the present application, the lifting drive 61 only needs to move the gear clamping part 62 to the gear 31, and the screw clamping part 63 can be driven to move to the screw 32 by the in-position drive 631, thereby ensuring that the gear clamping part 62 and the screw clamping part 63 can accurately move to the set clamping position.

[0046] Furthermore, the positioning drive member 631 includes a positioning cylinder arranged on the separation plate 71 along an inclined direction, and the positioning cylinder can drive the screw pneumatic clamp 632 to move along the inclined direction. The positioning cylinder is limited to being arranged along the inclined direction, which can avoid the lifting movement of the lifting drive unit 61 and make the structure of the material taking component 6 more compact.

[0047] In some embodiments, see Appendix Figure 5 As shown, the gear clamping part 62 includes a clamping base plate 621, a rotating driving member 622 (such as a motor), and a gear pneumatic clamping jaw 623. The clamping base plate 621 is fixedly connected to the material taking base plate 64. The rotating driving member 622 is installed on the clamping base plate 621 to drive the gear pneumatic clamping jaw 623 to rotate. The gear pneumatic clamping jaw 623 is used to clamp the gear 31 with the screw gear 3. The setting of the rotating driving member 622 can drive the gear 31 located on the gear pneumatic clamping jaw 623 to rotate, so that the meshing surface of the gear 31 can be fully sprayed by the refueling assembly 4 during the rotation process.

[0048] It should be noted that the gear pneumatic clamp 623 can adopt an internal support type clamping method, while the screw pneumatic clamp 632 can adopt an external clamping method.

[0049] In some embodiments, see Appendix Figure 6 As shown, the material transfer base 51 is provided with a linear module 53 and a guide rail 54 arranged in parallel, and the linear module 53 and the guide rail 54 are arranged in the horizontal direction; the sliding base plate 52 is connected to the linear module 53 and is slidably arranged on the guide rail 54 through a connecting seat. The setting of the guide rail 54 makes the movement of the sliding base plate 52 more stable.

[0050] In some embodiments, see Appendix Figure 7 As shown, a lifting assembly 8 for lifting the pallet 2 is provided at the refueling station, and the lifting assembly 8 includes a lifting plate that can be lifted and lowered under the action of a lifting drive; when the lifting plate rises, the lifting plate can support the pallet 2 located at the refueling station and make the pallet 2 separate from the assembly conveyor line 1. The setting of the lifting assembly 8 allows the pallet 2 to stay at the refueling station, so as to facilitate the refueling operation of the screw gear 3 on the pallet 2. Furthermore, a stop assembly is also provided at the refueling station, and the stop assembly includes stop plates 9 symmetrically arranged on both sides of the assembly conveyor line 1, and the stop plates 9 can abut against the upper end surface of the pallet 2 to limit the staying height of the pallet 2 at the refueling station.

[0051] In some embodiments, the refueling assembly 4 includes a refueling rack 41 mounted on the assembly conveyor line 1 , and a refueling gun 42 arranged toward the tray 2 is disposed on the refueling rack 41 .

[0052] In some embodiments, the tray 2 is provided with a first position and a second position for placing the screw gear 3, wherein the first position is used to place the screw gear 3 that has not been refueled, and the second position is used to place the refueled screw gear 3. When the material taking component 6 takes the material from the tray 2, the material taking component 6 takes the screw gear 3 from the first position, and when the screw gear 3 is refueled, the material taking component 6 places the screw gear 3 at the second position.

[0053] In some embodiments, the lifting drive unit 61 may be driven by a dual cylinder.

[0054] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model.
