Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection of automobile transmission parts, in particular to a hidden semi-automatic sealing mechanism. Background Art

[0002] Before the air tightness test of the transfer case / final reducer assembly, the oil seals at both ends of the transfer case input shaft or final reducer output shaft need to be effectively sealed. Traditional sealing methods can be roughly divided into two categories: one is manual clamping and sealing, and the other is automatic clamping and sealing by equipment.

[0003] Among them, the advantage of manual clamping and sealing is that the manual clamping tooling is simple in design, with low initial investment and good economy, but the disadvantages are also obvious. For example, the consistency of manual sealing state is poor, and the clamping tooling is prone to bumping and falling during the picking process, which affects the sealing effect and has the risk of damaging the parts and seals. As for automatic clamping and sealing by equipment, it not only requires the configuration of standard safety doors and safety gratings, but also requires a large site space, with high investment costs, and inconvenient maintenance and cleaning of sealing components. It is usually only used in automatic inspection stations, and its usage scenarios are limited. Utility Model Content

[0030] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0031] See also Figure 1 and Figure 2 The present embodiment provides a hidden semi-automatic sealing mechanism, including a mounting frame 1, a conveyor roller 2, a pallet lifting assembly 3 and a deflection assembly 4. The mounting frame 1 is erected on a horizontal ground, and two synchronously moving conveyor rollers 2 are kept horizontal and parallel and spaced apart on the top of the mounting frame 1. The pallet lifting assembly 3 is arranged in a strip space between the two conveyor rollers 2 and can be lifted and lowered in a vertical direction. The swing arm 41 of the deflection assembly 4 can swing 1 / 4 of a circle from horizontal to vertical. A transverse sealing assembly 5 is vertically installed at the end of the swing arm 41. A sealing shaft 51 capable of sealing with a part is installed on the moving end of the transverse sealing assembly 5. The two deflection assemblies 4 are arranged in the strip space opposite to each other at a distance, and the pallet lifting assembly 3 is located between the two deflection assemblies 4.

[0032] When the hidden semi-automatic sealing mechanism of the present embodiment is in use, the tray 6 containing the parts is placed on the two conveyor rollers 2, and then the two conveyor rollers 2 are started to move synchronously until the tray 6 moves to the top of the tray lifting assembly 3; the tray lifting assembly 3 is then controlled to lift in the vertical direction to lift the tray 6 off the conveyor rollers 2 to achieve the positioning of the tray 6; then the deflection assemblies 4 on both sides are respectively controlled to swing, so that the transverse sealing assembly 5 moves until the sealing shaft 51 is coaxial with the sealing hole on the part; then the transverse sealing assembly 5 is controlled to drive the sealing shaft 51 to move transversely until the sealing shaft 51 is sealed with the sealing hole on the part, thereby semi-automatically completing the clamping and sealing of the part; thereafter, the part can be tested for air tightness, and after the air tightness test is completed, the transverse sealing assembly 5, the deflection assembly 4 and the tray lifting assembly 3 are controlled to reset in turn, and the part can be sent away from the mechanism through the conveyor rollers 2.

[0033] The hidden semi-automatic sealing mechanism of this embodiment solves the problems of poor sealing consistency of manual clamping tooling and easy bumping and damage to the sealing surface of the clamp through semi-automatic control; at the same time, a common conveyor roller is used to convey parts, and the pallet lifting assembly 3 and the deflection assembly 4 thereon are designed to be hidden in the strip space when not in operation, thereby overcoming the problems of high cost, large space occupied and inconvenient maintenance and cleaning of the automatic clamping sealing mechanism.

[0034] It should be noted that the original positions (ie, non-working positions) of the deflection assembly 4 and the tray lifting assembly 3 are both lower than the conveyor roller 2 , thereby not affecting the normal passage of the tray 6 containing parts on the conveyor roller 2 .

[0035] Preferably, the conveyor roller 2 is a manually driven roller, that is, the conveyor roller 2 is an unpowered roller, and the movement of the tray 6 on the conveyor roller 2 needs to be achieved by manual pushing or pulling.

[0036] Preferably, see Figure 2 The tray lifting assembly 3 is provided with a forward stopper 7 and a backward elastic stopper 8 on both sides of the strip space. The forward stopper 7 is arranged near the end of the conveying roller 2 and is higher than the strip space, and the backward elastic stopper 8 is arranged near the beginning of the conveying roller 2 and is higher than the strip space. When the tray 6 containing parts moves to the test station area, the front end will be close to the forward stopper 7 for forward direction limit, and the rear end will be close to the backward elastic stopper 8 for backward direction limit. The forward stopper 7 and the backward elastic stopper 8 are used in combination to realize the initial positioning of the tray 6 to ensure the clamping and sealing of the parts.

[0037] Preferably, in this embodiment, the forward stopper 7 is pneumatically raised and lowered. In the initial state, the forward stopper 7 is higher than the strip space setting. After the test is completed, the forward stopper 7 can be controlled to pneumatically descend, thereby releasing the forward direction limit of the tray 6 containing parts; and the backward elastic stopper 8 includes a fixed block and a hinged block, one end of the hinged block is hinged on the fixed block, and the other end of the hinged block is abutted against the spring on the fixed block, thereby realizing the limitation of the backward direction of the tray 6 containing parts only.

[0038] Preferably, the hidden semi-automatic sealing mechanism of this embodiment also includes a controller, a left-hand control box (not shown in the figure) and a right-hand control box (not shown in the figure), the tray lifting assembly 3, the deflection assembly 4, the lateral sealing assembly 5, the left-hand control box and the right-hand control box are all connected to the controller signal, the left-hand control box and the right-hand control box are arranged at intervals on the mounting frame 1, and the left-hand control box is located on the left side of the right-hand control box.

[0039] It should be noted that a control program is pre-stored in the controller. When the tray lifting assembly 3, the deflection assembly 4 and the transverse sealing assembly 5 need to be controlled, the control switches on the left-hand control box and the right-hand control box need to be pressed simultaneously to trigger the movement.

[0040] Specifically, when it is necessary to seal the parts, press the control switches on the left-hand control box and the right-hand control box at the same time, the tray lifting assembly 3 is lifted, and then the deflection assemblies 4 on both sides are flipped upward synchronously, and finally the transverse sealing assembly 5 is extended; when it is necessary to release the seal of the parts, press the control switches on the left-hand control box and the right-hand control box at the same time, and the transverse sealing assembly 5, the deflection assembly 4 and the tray lifting assembly 3 are reset in turn.

[0041] Preferably, see Figure 2 The pallet lifting assembly 3 includes a lifting drive member 31 and a pallet positioning plate 32 . The lifting drive member 31 is vertically fixed to the bottom of the mounting frame 1 with the driving end upward, and the driving end of the lifting drive member 31 is vertically connected to the pallet positioning plate 32 .

[0042] The specific process of the pallet lifting assembly 3 positioning the pallet 6 is as follows: the lifting drive component 31 is controlled to start, and the driving end of the lifting drive component 31 rises to drive the pallet positioning plate 32 to rise, and the pallet positioning plate 32 is raised above the conveying roller 2 to lift and position the pallet 6 containing the parts.

[0043] Preferably, in this embodiment, the lifting drive member 31 can be a lifting cylinder or a push rod motor.

[0044] Preferably, see Figure 2 The deflection assembly 4 includes a lateral movement driving member 42 and a swing arm 41. The lateral movement driving member 42 is horizontally arranged at the bottom of the mounting frame 1. The middle position of the swing arm 41 is hinged to the mounting frame 1. One end of the swing arm 41 is hinged to the driving end of the lateral movement driving member 42, and the other end is installed with a lateral sealing assembly 5.

[0045] The specific deflection process of the deflection assembly 4 is: control the lateral movement driving member 42 to start, and the driving end of the lateral movement driving member 42 moves laterally to drive the swing arm 41 to deflect synchronously, so that the lateral sealing assembly 5 moves until the sealing shaft 51 is coaxial with the sealing hole on the part.

[0046] Preferably, the lateral movement driving member 42 adopts a movement cylinder equipped with a speed regulating valve. After the movement cylinder is equipped with the speed regulating valve, the swing speed of the swing arm 41 can be adjusted as needed to ensure the safety of the operator during the clamping and sealing process.

[0047] Preferably, see Figure 2The transverse sealing assembly 5 includes a transverse sealing driving member 52 and a sealing shaft 51. The transverse sealing driving member 52 is vertically arranged at the end of the swing arm 41, and the sealing shaft 51 is axially fixed on the driving end of the transverse sealing driving member 52. When the transverse sealing assembly 5 moves with the swing arm 41 until the sealing shaft 51 is coaxial with the sealing hole on the part, the transverse sealing driving member 52 drives the sealing shaft 51 to move into the sealing hole of the part until the sealing shaft 51 is sealed and matched with the sealing hole. At this time, the clamping and sealing of the part is completed.

[0048] Preferably, in this embodiment, the transverse sealing drive member 52 can be a transverse cylinder or a push rod motor.

[0049] It should be noted that the movements of the lifting drive member 31, the lateral movement drive member 42 and the lateral sealing drive member 52 are all triggered and maintained by simultaneously and long pressing the control switches on the left-hand control box and the right-hand control box.

[0050] At present, this hidden semi-automatic sealing mechanism is used in the air tightness detection station of the new Jaguar Land Rover rear main reducer assembly. From mass production to the present (a total of 4 years, with a cumulative production of about 200,000 units), no sealing problems have occurred, the sealing shaft 51 has not been damaged or replaced due to collision, and no maintenance has been performed.

[0051] Compared with the problems of poor sealing consistency and easy scratches on the sealing surface which may damage the seals due to manual clamping and the disadvantages of automatic clamping and sealing devices which require the configuration of standard safety doors and safety gratings (high investment cost) and require a large site space, the practical effect of this hidden semi-automatic sealing mechanism is remarkable.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
