Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a fixing fixture for processing an automobile flywheel housing. Background Art

[0002] The gearbox flywheel housing is an important component of the automobile transmission system. It is located between the engine and the gearbox and can provide the required interfaces for other transmission components such as the flywheel and clutch. When the flywheel is working, the flywheel housing provides a mounting base for it and indirectly participates in the transmission process of the engine torque to the gearbox. Therefore, the flywheel housing has high requirements for its own strength. The flywheel housing is mostly made of cast iron. During processing, the operator usually lifts the flywheel housing and places it horizontally on the fixture, which is fixed by the fixture to facilitate subsequent processing.

[0003] During the operation of a common flywheel housing fixing fixture, due to its heavy weight, multiple operators are often required to cooperate with the lifting equipment. In the process of lowering the flywheel housing onto the fixture, the placement position of the flywheel housing is manually adjusted so that the flywheel housing can be accurately aligned with the positioning points and clamping points on the fixture. However, since manual operation often has certain errors, when the flywheel housing is placed on the fixture but the positioning column on the fixture is not aligned with the opening on the flywheel housing, the operators are required to push the flywheel housing together to enable the positioning column to smoothly align with the opening on the flywheel housing. At this time, the positioning column is likely to cause certain scratches on the surface of the flywheel housing, which is harmful to the gearbox. Utility Model Content

[0004] In order to solve the above problems, the utility model provides the following technical solutions:

[0012] Furthermore, the positioning contact portion includes a fixing seat arranged at the movable end of the lifting device, and a movable ball arranged inside the fixing seat, and the surface of the movable ball away from the lifting device can contact the middle shell of the car.

[0013] Furthermore, the material guiding protrusion is an overall conical structure with a smooth surface, a guide ball is provided between the interior of the fixing seat and the movable ball, and a soft rubber pad is provided on the surface of the movable ball.

[0014] Furthermore, a mounting seat is provided at the movable end of the lifting device, and the fixed seat is provided on the surface of the mounting seat.

[0015] Furthermore, the surface of the mounting seat is provided with a limiting protrusion that can extend into the interior of the fixing seat, and the surface of the fixing seat is provided with an opening that can allow the limiting protrusion to extend into.

[0019] Furthermore, a plurality of vertical stoppers are provided on the surface of the placement table, and when the flywheel housing is placed on the fixing fixture, the vertical stoppers are in contact with the side edges of the flywheel housing.

[0020] Beneficial Effects

[0021] Compared with the prior art, the utility model can cooperate with the adaptive positioning component through the lifting and adjusting component. When the gearbox flywheel housing needs to be processed, after the lifted flywheel housing is placed on the fixture, the lifting control part first contacts the flywheel housing, and the lift control part lowers the flywheel housing. At this time, the positioning piece and the material guide protrusion can gradually contact the flywheel housing, allowing the material guide protrusion to guide the flywheel housing, prompting the positioning piece to smoothly enter the corresponding hole on the flywheel housing, reducing the manual work of transporting or guiding the flywheel housing. At the same time, the movable ball can allow the operator to directly move the flywheel housing and adjust its position after the flywheel housing contacts it, prompting the positioning piece to be roughly aligned with the corresponding hole on the flywheel housing, effectively reducing the scratches caused to the outside of the flywheel housing during the subsequent clamping process of the flywheel housing.

[0036] See also Figure 1-6 A fixing fixture for processing an automobile flywheel housing comprises a clamping base capable of clamping the flywheel housing, a lifting and adjusting component 2 arranged on the clamping base, and an adaptive positioning component 3.

[0037] Among them, the clamp base 1 is a common flywheel shell clamping and positioning structure, specifically including a support base 11, a placement table 12 arranged on the support base 11, and a clamp structure 13 arranged on the placement table 12. The clamp structure 13 can be a common clamping structure, which can cooperate with the placement table 12 to achieve clamping and fixing of the flywheel shell.

[0038] The lifting and adjusting component 2 includes a lifting control part 21 arranged on the placement table 12, and a positioning contact part 22 arranged at the movable end of the lifting control part 21 and capable of contacting the car middle shell. The adaptive positioning component 3 includes a positioning piece 31 arranged on the placement table 12, and a material guiding protrusion 32 arranged at one end of the positioning piece 31 away from the placement table 12. To ensure that the flywheel shell can contact the lifting and controlling part 21 first, the maximum height to which the lifting and controlling part 21 can be extended is higher than the maximum height of the adaptive positioning component 3. The lifting and controlling part 21 can drive the car middle shell in contact with the positioning contact part 22 to lift and lower, and when the car middle shell descends, the adaptive positioning component 3 can be inserted into the positioning hole corresponding to the surface of the car middle shell.

[0039] Specifically, the lifting control part 21 includes a lifting device 211 arranged on the placement platform 12, and a control module 212 capable of controlling the lifting device 211. The lifting device 211 can drive the car body to make vertical linear motion. The lifting device 211 can be a common hydraulic cylinder or a pneumatic cylinder, and the positioning contact part 22 includes a fixed seat 221 arranged at the movable end of the lifting device 211, and a movable ball 222 arranged inside the fixed seat 221. The surface of the movable ball 222 away from the lifting device 211 can contact the car body. After the flywheel housing is placed on the positioning contact part 22, the movable ball 222 can be used to enable the flywheel housing to freely adjust its position on the lifting device 211 according to the operator's usage requirements, thereby ensuring that the subsequent flywheel housing and the positioning member 31 can be smoothly aligned.

[0040] In order to prevent the material guide protrusion 32 from causing too obvious scratches on the surface of the flywheel housing, the material guide protrusion 32 is generally a conical structure with a smooth surface. At the same time, in order to increase the activity of the movable ball 222, a guide ball 223 is provided between the inside of the fixed seat 221 and the movable ball 222, and a soft rubber pad is provided on the surface of the movable ball 222.

[0041] In some embodiments, in order to facilitate the disassembly of the fixing seat 221 and facilitate the subsequent use process to adapt to the operator who does not need to adjust the position of the flywheel housing to adjust the height of the flywheel housing, a mounting seat 224 is provided at the movable end of the lifting device 211, and the fixing seat 221 is arranged on the surface of the mounting seat 224. The surface of the mounting seat 224 is provided with a limiting protrusion 225 that can extend into the interior of the fixing seat 221. The surface of the fixing seat 221 is provided with an opening that can allow the limiting protrusion 225 to extend into. After the limiting protrusion 225 extends into the interior of the fixing seat 221, it can contact the movable ball 222, thereby achieving the limitation of the position of the movable ball 222.

[0042] In other embodiments, in order to prevent the movable ball 222 from being unable to move when the operator needs to adjust the position of the flywheel housing, a lifting member 226 is provided on the surface of the mounting seat 224. The lifting member 226 is provided at a position between the fixed seat 221 and the mounting seat 224. When the lifting member 226 is installed on the surface of the mounting seat 224, the limiting protrusion 225 provided on the surface of the mounting seat 224 does not contact the movable ball 222. The lifting member 226 is composed of a plurality of semi-rings that can form a circular ring structure, and adjacent semi-rings are connected by connecting members 227. The lifting member 226 can be removed from the surface of the mounting seat 224 when the fixed seat 221 is installed on the surface of the mounting seat 224. The fixed seat 221 and the mounting seat 224 are connected by threads, and the lifting member 226 and the mounting seat 224 are connected by threads.

[0043] For further information, see Figure 1 In order to further adjust the height position of the flywheel housing, a plurality of vertical limit members 4 are provided on the surface of the placement table 12. When the flywheel housing is placed on the fixing fixture, the vertical limit members 4 are in contact with the side of the flywheel housing.
