[0038] (An explanation of the origin of the invention, the thinking process, etc. can be given)

[0039] In the automotive industry, the transmission is one of the core components of the vehicle, and its assembly quality is directly related to the reliability, smoothness and durability of the vehicle. The transmission front housing, as the bearing of key parts such as bearings, its assembly precision is particularly important.

[0040] The traditional assembly method highly depends on manual operation: the operator needs to manually take and place the front shell and the bearing, align and press-fit by personal experience and hand feeling, and realize assembly in place through repeated adjustment. In this process, the assembly precision is completely dependent on the instantaneous state of the operator.

[0041] Therefore, the inventor found through research and improvement exploration that the traditional manual assembly relying on manual perception leads to the following problems: first, the installation precision is low, the product quality cannot be guaranteed, and it is easily affected by subjective factors. If the assembly position is not accurate, it will increase the difficulty of subsequent assembly, and even cause secondary rework, resulting in long operation cycle and low efficiency, which cannot meet the high rhythm requirements of modern production lines. Second, it relies on the cooperative operation of multiple skilled engineers, which is high in labor cost and is not conducive to the standardization and digitization management of the production process.

[0042] Therefore, the embodiment of the present specification proposes a hybrid dual-motor front shell assembly device: the overall idea is to set up an integrated assembly device, use a jacking and rotating mechanism to realize automatic circulation and precise positioning of the workpiece, and use a bearing feeding assembly with three-dimensional motion capability to control at least two pressure head assemblies equipped with detachable pressure heads, accurately move and perform press-fitting operation in three-dimensional space, so as to replace manual operation with automatic equipment and realize flexible assembly with high efficiency, high precision and multi-station cooperation.

[0043] The technical solutions provided by the embodiments of the present application will be described below with reference to the drawings.

[0044] As shown in Figure 2 The embodiment of the present specification provides a hybrid dual-motor front shell assembly device, which comprises a base, a bearing feeding assembly and a jacking and rotating mechanism.

[0045] The base is used to install the jacking and rotating mechanism and the bearing feeding assembly.

[0046] The jacking and rotating mechanism is installed on the base and is used to carry and transport workpieces.

[0047] The bearing feeding assembly is installed on the base and is arranged on the side of the press-fitting station of the jacking and rotating mechanism, and is used to perform press-fitting operation of parts.

[0048] The bearing feeding assembly is arranged above the press-fitting station and comprises a support frame, a multi-dimensional driving assembly and a pressure head assembly.

[0049] The support frame is used to provide installation and support for the multi-dimensional driving assembly and the pressure head assembly.

[0050] The multi-dimensional driving assembly comprises a Y-direction driving part for driving the pressure head assembly to move along the Y axis, an X-direction driving part for driving the pressure head assembly to move along the X axis, and a Z-direction driving part for driving the pressure head assembly to be pressed along the Z axis; the multi-dimensional driving assembly drives the pressure head assembly to move in the three-dimensional space;

[0051] The pressure head assembly is at least two, connected to the output end of the Z-direction driving part, and a detachable pressure head is arranged on the pressure head assembly, and the pressure head assembly is used to move to a target position under the driving of the multi-dimensional driving unit and perform a pressing work on the corresponding part.

[0052] As shown in Figures 1-2 The installation basis of the entire hybrid double-motor front shell assembly device is the base 36, which is the base of the entire mechanism. The bearing feeding mechanism 1 is assembled on one side of the jacking and rotating mechanism 2. The specific working process is as follows: the workpiece (such as a gearbox front shell) is placed on the jacking and rotating mechanism 2 feeding position, the jacking and rotating mechanism 2 rotates the workpiece to the bearing feeding assembly 1 position, then the bearing feeding assembly drives multiple replaceable pressure heads through its multi-dimensional motion system to move precisely in the three-dimensional space, and automatically assemble the bearing. After completion, it can be rotated to the position of the next process, replacing manual operation, improving assembly precision, efficiency and consistency.

[0053] In some embodiments, the support frame comprises at least two columns, a middle mounting plate connected between the columns, at least two support columns, and a top cover plate mounted above the top of the columns and the support columns.

[0054] In implementation, as shown in Figure 2 Two columns 4 are connected by a middle mounting plate 6 to form a main support structure. Two connecting frames 7 are mounted on the middle mounting plate 6. A top cover plate 8 is mounted on the top of the connecting frames 7 and the support columns 5, which are jointly supported.

[0055] In some embodiments, the support column 5 can be arranged on the center line of the middle mounting plate 6 and extend upward to form an outside center support point of the top cover plate 8, which jointly constitutes the support of the top cover plate 8 with the connecting frame 7.

[0056] In some embodiments, the Y-direction driving part is mounted on the top cover plate and comprises a Y-direction motor and a Y-direction guide rail pair; the X-direction driving part comprises an X-direction motor and an X-direction guide rail pair mounted on the sliding part of the Y-direction guide rail pair, so that the X-direction driving part translates synchronously with the Y-direction driving part;

Only a single Z-direction electric cylinder is used to control the precise movement of multiple pressure head assemblies 16 to different working positions through the coordinated movement in the X and Y directions. Compared with the traditional scheme in which an electric cylinder is separately configured for each pressure head to control the movement, the integrated design of the present application eliminates the need for multiple electric cylinders, significantly saves costs, and simplifies the installation steps.

[0064] The bearing pressure head assembly 20 is used to perform the pressure assembly operation and includes a pressure head seat 31, a quick-change assembly 33, and a bearing pressure head 32. The quick-change assembly 33 can adopt the form of a quick-change pin, a buckle, or a modular interface.

[0065] The moving plate 21 is the base and moving carrier of the right side pressing head. Through the moving plate 21, the moving guide rail pair 22 (such as a moving guide rail slider) and the moving driving device 24 (such as a moving cylinder), the right side pressing head can be accurately moved in a small range in the horizontal plane, so as to accurately adjust the relative horizontal distance between the two pressing heads, so that a set of pressing head assembly can flexibly adapt to the changing center distance of the bearing mounting hole on the workpiece of different specifications, and the flexibility and universality of the equipment are significantly enhanced.

[0066] The pressing head base plate 17 is the base and moving carrier of the left side pressing head.
