Description

Technical Field

[0001] The utility model relates to the technical field of engine assembly, in particular to a pressing device for an automobile engine bearing cap. Background Technique

[0002] The installation of an automobile engine bearing cap usually consists of several steps. First, a pressing device is used to accurately press the bearing cap onto the corresponding position of the engine cylinder block to ensure the fitting accuracy and sealing performance between the bearing cap and the cylinder block. Then, a special bolt tightening tool is used to install bolts to firmly fix the bearing cap on the cylinder block. Different pressing devices may have different functional designs. Generally, the pressing device mainly focuses on the pressing operation.

[0003] Common devices for pressing automobile engine bearing caps in the prior art generally have the disadvantage of simple structure, which brings many inconveniences to actual production applications. Specifically, the pressing device lacks the functions of temporarily storing and guiding the connecting components (bolts). After the operator controls the pressing device to complete the pressing of the bearing cap body and the cylinder block, if the pressing device is not lifted and removed, it will hinder the placement of the connecting components (bolts). If the pressing device is lifted and removed and then the connecting components (bolts) are placed, there is a risk of touching the bearing cap body and causing it to move. In order to enrich the structure of the device and improve its functionality, a pressing device for an automobile engine bearing cap is proposed here. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Referring to Figures 1-5 , an automobile engine tile cover pressing device includes a lifting rod 1 and a tile cover body 2. The lifting rod 1 can be installed on the ceiling of the processing workshop by means of a lifting component such as a cylinder or a hydraulic cylinder.

[0027] An upper screw rod 4 is provided on the lifting rod 1 through an upper fixing frame 3, and a lower screw rod 13 is provided on the lifting rod 1 through a lower fixing frame 12. A positioning plate 5 is threadedly sleeved on the upper screw rod 4 through an upper limit mechanism, and a shielding frame 15 is provided on the lower fixing frame 12 through a lower limit mechanism. A fixing plate 9 is installed on the lifting rod 1, and a stabilizing cylinder 11 is provided on the fixing plate 9 through a placing opening 10. A transmission cavity 16 is provided inside the lifting rod 1. Both the upper screw rod 4 and the lower screw rod 13 extend into the transmission cavity 16. A driving motor 8 is provided on the lifting rod 1. Both the upper screw rod 4 and the lower screw rod 13 are connected to the driving motor 8 through a rotating mechanism.

[0028] The upper limit mechanism includes an upper limit rod 6 installed between the lifting rod 1 and the upper fixing frame 3, and the upper limit rod 6 slidably penetrates through the positioning plate 5. The lower limit mechanism includes a lower limit rod 14 installed between the lifting rod 1 and the lower fixing frame 12, and the lower limit rod 14 slidably penetrates through the shielding frame 15. The above-mentioned upper limit rod 6 and lower limit rod 14 respectively realize the limiting of the positioning plate 5 and the shielding frame 15, so as to prevent them from rotating together with the upper screw rod 4 and the lower screw rod 13 respectively.

[0029] The rotating mechanism includes a driving gear 17 disposed in the transmission cavity 16 and connected to the output shaft of the driving motor 8. A transmission gear 18 connected to the upper screw rod 4 and the lower screw rod 13 is also provided in the transmission cavity 16. The driving gear 17 meshes with a plurality of transmission gears 18. Both the driving gear 17 and the transmission gears 18 are bevel gears, and the meshing mode between the driving gear 17 and the transmission gears 18 is vertical meshing. Being set as bevel gears and vertical meshing can achieve the power transmission of the driving motor 8, save the space required for the transmission components, and reduce the overall size of the device.

[0030] Protective pads are provided on the surfaces of the lifting rod 1 and the positioning plate 5 that contact the tile cover body 2. The protective pads are adhesively connected to both the lifting rod 1 and the positioning plate 5. The protective pads are made of rubber, and anti-slip patterns are provided on the surfaces of the protective pads that contact the tile cover body 2. The above-mentioned rubber protective pads can prevent damage to the contact parts of each component with the tile cover body 2, and the anti-slip patterns have a good anti-slip effect. The adhesive connection can be directly torn off and replaced when the wear is relatively serious.

[0031] The shielding frame 15 is L-shaped, and the inner wall of the placing opening 10, the inner wall of the stabilizing cylinder 11, and the surface of the shielding frame 15 that contacts the stabilizing cylinder 11 are all polished. The above polishing treatment ensures the smoothness of the bolt assembly falling in the placing opening 10 and the stabilizing cylinder 11, and ensures the smoothness when the shielding frame 15 moves away from the stabilizing cylinder 11.

[0032] A placing channel 7 is provided on the lifting rod 1, and the driving motor 8 is disposed in the placing channel 7. Due to the provision of this placing channel 7, the heat generated when the driving motor 8 works can be dissipated in time, avoiding damage to the driving motor 8 caused by overheating.

[0033] When the utility model is in use, components such as the lifting rod 1 can achieve lifting operations with the help of components such as cylinders. The automobile engine cylinder block can be located below components such as the lifting rod 1 and positioned by the positioning and fixing components in the prior art. The tile cover body 2 to be installed is located below the lifting rod 1. At this time, the driving motor 8 is started. The driving motor 8 drives the upper screw rod 4 and the lower screw rod 13 to rotate through the driving gear 17 and the transmission gears 18. When the upper screw rod 4 rotates, the positioning plate 5 moves to realize the clamping and positioning operation of the tile cover body 2. When the lower screw rod 13 rotates, the shielding frame 15 moves and blocks the opening of the stabilizing cylinder 11. At this time, the bolt assembly for connecting the engine cylinder block and the tile cover body 2 is placed into the placing opening 10 and located in the stabilizing cylinder 11. Then, components such as cylinders are started, and finally the tile cover body 2 is driven to descend with the help of components such as the lifting rod 1 to complete the connection with the engine cylinder block, and wait for a while to complete the operation of being pressed in place.

[0034] Then the driving motor 8 is reversed. At this time, the positioning plate 5 moves away from the tile cover body 2 to release its positioning support. At the same time, the shielding frame 15 moves away from the stabilizing cylinder 11. At this time, the connecting components (bolts) in the stabilizing cylinder 11 fall into the connecting holes on the tile cover body 2. Then the lifting rod 1 and other components rise and detach, leaving enough space for the operator to install the connecting components.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
