Description

Technical Field

[0001] The utility model relates to a horizontal oil seal pressing device, belonging to the technical field of oil seal crimping equipment. Background Art

[0002] Oil seals are mechanical components used to seal oil. Oil is the most common liquid substance in the transmission system, and it also refers to general liquid substances. It isolates the parts that need lubrication from the output parts in the transmission parts to prevent the lubricating oil from leaking. The seals used for static and dynamic seals are called seals. The representative form of oil seals is TC oil seals, which are double-lip oil seals with self-tightening springs that are completely covered with rubber. The oil seals generally refer to this TC skeleton oil seal.

[0003] Generally, there is only one oil seal on the installation housing, so the traditional oil seal equipment only needs to use a single-stroke push press to meet the press-fitting requirements of a single oil seal.

[0004] However, in the current prior art, there is a tubular shaft-shaped installation shell, and oil seals need to be pressed on both axial ends. The traditional method is to use a press machine to press the oil seals separately, but the pressing efficiency is low. At the same time, in the automation design process, two pressing stations need to be set up in sequence, which makes the construction cost of the automated production line high.

[0005] In addition, in traditional press-fitting equipment, there are also relatively set bidirectional synchronous presses, but traditional bidirectional synchronous presses generally use bidirectional crimping after clamping and fixing the shell. Clamping will damage the shell, and there is also a problem of relative force in the bidirectional crimping process. Too loose clamping will also cause relative scratches. On this basis, improvements are made by using a pressure head with one side active and one side driven, which can eliminate the problem of traditional requirements for excessive clamping force causing damage to the shell. However, the traditional fixed driven head has a relatively fixed position, and the relative crimping on both sides has no relative buffering, which will cause crimping damage or inadequate crimping. In addition, when installing the shell loading, it needs to be axially displaced for loading, which is not conducive to being set up in an automated production line, and has relatively high requirements for the automated loading stroke and axial position. Utility Model Content

[0006] The utility model aims to solve the above-mentioned deficiencies of the prior art and proposes a horizontal oil seal pressing device in view of the problem that the traditional bidirectional press may cause damage to the shell.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A horizontal oil seal press-fitting device comprises a fixed carrier plate and a press base provided at the bottom of the fixed carrier plate and having a horizontal linear adjustable displacement;

[0010] The active press mechanism includes an active crimping end and a crimping driving source transmission-connected to the active crimping end, and the passive press mechanism includes a passive crimping end. The active crimping end and the passive crimping end are respectively provided with a crimping end head and a floating crimping seat connected to the crimping end head.

[0011] Preferably, the active press mechanism and the driven press mechanism are respectively provided with a limiting mechanism for locking or loosening the crimping end.

[0012] Preferably, the limiting mechanism comprises at least two elastic locking pins with telescopic elastic displacement for radially interfering with the crimping terminal, and a linear driving source that is transmission-connected with the elastic pins to lock the linear driving source;

[0013] The crimping terminal is provided with an annular recess for cooperating with the elastic locking pin.

[0014] Preferably, the floating crimping seat comprises a base, a matching seat, and an elastic element arranged between the base and the matching seat, and the crimping end is detachably arranged on the matching seat.

[0015] Preferably, the crimping terminal includes a central positioning column and a crimping ring body arranged on the periphery of the central positioning column.

[0016] Preferably, the press mount is slidably coupled to the bottom of the fixed carrier plate, and the fixed carrier plate is provided with a displacement driving source that is transmission-connected to the press mount.

[0017] Preferably, at least two parallel slide rails are provided on the top of the press carrier, and a slider assembly corresponding to the slide rails is provided on the fixed carrier.

[0018] Preferably, the press carrier comprises a concave-shaped carrier body with two raised piles, wherein the active press mechanism is arranged on one of the raised piles, and the driven press mechanism is arranged on the other raised pile.

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] The utility model provides a horizontal oil seal pressing device, such as Figures 1 to 5As shown, it includes a fixed carrier plate 1 and a press base 2 provided at the bottom of the fixed carrier plate 1 and having horizontal linear adjustable displacement.

[0032] An active press mechanism 3 and a driven press mechanism 4 are arranged on the press carrier 2 and are arranged relatively along the horizontal linear adjustment displacement direction of the press carrier.

[0033] The active press mechanism 3 includes an active crimping end 31 and a crimping drive source 32 which is transmission-connected to the active crimping end. The passive press mechanism includes a passive crimping end 41. The active crimping end 31 and the passive crimping end 41 are respectively provided with a crimping end head 5 and a floating crimping seat 6 which is connected to the crimping end head 5.

[0034] Specific implementation process and principle description:

[0035] When loading the shell, the crimping drive source 32 drives the active crimping end 31 to separate from the driven crimping end 41, so that the gap between the active crimping end 31 and the driven crimping end 41 is sufficient for loading the shell. At this time, the press base 2 is displaced at the bottom of the fixed carrier plate 1 to meet the non-interference shell loading requirements.

[0036] After the shell is loaded, the press carrier 2 is driven to move so that the driven crimping end 41 is docked with one end of the shell, and then the crimping drive source 32 of the active press mechanism 3 is driven to crimp, and the relatively synchronous crimping operation of the active crimping end 31 and the driven crimping end 41 is achieved through a single drive.

[0037] In this way, the bidirectional synchronous crimping requirements of the automatic feeding mechanism are met. After the crimping operation is completed, the active end is disengaged, and then the driven end is disengaged by driving the press carrier 2, which facilitates unloading after picking up and runs smoothly and efficiently.

[0038] In a specific embodiment, the active press mechanism and the driven press mechanism are respectively provided with a limiting mechanism 7 for locking or loosening the crimping terminal.

[0039] Specifically, after the crimping is completed, the current floating compressed crimping end can be locked by the limiting mechanism 7. After locking, the active press mechanism is reset to meet the shell feeding interval requirements, and the linear displacement of the crimping drive source 32 is reduced.

[0040] In a specific embodiment, the limiting mechanism 7 includes at least two elastic locking pins 71 with telescopic elastic displacement for radially interfering with the crimping end, and a linear driving source 72 that is transmission-connected and locked with the elastic pin; the crimping end 5 is provided with an annular recess 50 for cooperating with the elastic locking pin.

[0041] This satisfies the radial locking interference fit and release requirements.

[0042] In a specific embodiment, the floating crimping seat 6 includes a base 61, a matching carrier 62, and an elastic element 63 disposed between the base and the matching carrier, and the crimping terminal is detachably disposed on the matching carrier.

[0043] This meets the needs of rapid changeover and the equipment utilization rate is relatively high.

[0044] In a specific embodiment, the crimping terminal 5 includes a central positioning column 51 and a crimping ring body 52 arranged on the periphery of the central positioning column.

[0045] This satisfies the space requirement for the oil seal. The central positioning column 51 is easy to realize positioning and guiding.

[0046] In a specific embodiment, the press carrier 2 is slidably matched to the bottom of the fixed carrier 1, and the fixed carrier is provided with a displacement driving source 10 which is transmission-connected to the press carrier.

[0047] The linear displacement adjustment control of the press carrier 2 can be conveniently realized through the displacement driving source 10, thereby meeting the coordination requirements of avoidance and loading.

[0048] In a specific embodiment, at least two parallel slide rails 21 are provided on the top of the press base 2, and a slider assembly 11 corresponding to the slide rails is provided on the fixed carrier plate.

[0049] This meets the needs of linear displacement guide matching.

[0050] In a specific embodiment, the press carrier 2 includes a concave-shaped carrier body 23 with two raised piles 22, wherein an active press mechanism is disposed on one of the raised piles and a passive press mechanism is disposed on the other raised pile.

[0051] The active press mechanism and the driven press mechanism are carried at intervals by means of the two raised piles 22 of the concave-shaped carrier body 23, thereby meeting the demand for providing a shell carrying space, and the overall structure of the press carrier 2 is simple and ingenious.

[0052] From the above description, it can be found that the utility model is a horizontal oil seal pressing device, which adopts a horizontal matching structure. Only one crimping power end is needed to meet the requirements of the synchronous crimping operation of two oil seals. At the same time, it is easy to achieve the avoidance and matching operation with the shell loading and unloading, and the operation is efficient and smooth. It can achieve two-way crimping end locking, that is, meet the locking requirements under the elastic compression state, thus reducing the crimping stroke requirements, controlling the equipment cost, and using the unlocked elastic reset to easily achieve pre-loading operations. It is particularly suitable for cooperation with the automatic feeding mechanism, and it is easy to realize the construction of an automated production line.
