For example, at the output end of the transmission main housing, the parts requiring press-fitting include output shaft needle roller bearings, needle roller bearing retaining rings, rectangular sealing sleeves, rectangular sealing sleeve retaining rings, deep groove ball bearings, output shaft oil seals, locating pins, shift shaft oil seals, and many other parts. Each part requires a separate press station, leading to a large number of servo presses, a large number of operators, and correspondingly high investment costs. Utility Model Content

[0003] To address the above deficiencies, the purpose of this utility model is to provide an assembly equipment for the output end parts of a longitudinally mounted transmission main housing. This assembly equipment can assemble multiple parts, requires fewer servo presses, fewer operators, occupies less space, and has low investment costs.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: An assembly device for the output end parts of a longitudinally mounted transmission main housing includes a first servo press vertically mounted on the top of a frame, with a pressure head connecting rod connected to the power output end of the first servo press; a laterally slidable pressure head mounting backplate is mounted on the frame below the first servo press, with multiple pressure heads for pressing different parts mounted side-by-side laterally on the pressure head mounting backplate, each pressure head being vertically slidably mounted on the pressure head mounting backplate via a pressure head mounting bracket; a press connecting block is fixed to the upper part of the pressure head mounting bracket, and the press connecting block is provided with a connecting rod slot for connecting to the pressure head connecting rod; a laterally slidable transmission positioning fixture is mounted on the base of the frame.

[0005] The lower end of the pressure head connecting rod is an inverted T-shaped structure, and the connecting rod slot is an inverted T-shaped slot that matches the lower end of the pressure head connecting rod, and the connecting rod slot extends laterally through the press connecting block.

[0006] The base is horizontally mounted with a first electric lead screw, and the gearbox positioning fixture is fixedly connected to the lead screw nut of the first electric lead screw.

[0007] The base is also equipped with a positioning tooling guide rail that is parallel to the first electric lead screw, and the gearbox positioning tooling is fixedly connected to the slider of the positioning tooling guide rail.

[0008] The positioning fixture limit block is installed on the base located at the end of the positioning fixture guide rail.

[0009] The frame is equipped with a second electric lead screw, and the pressure head mounting back plate is fixedly connected to the lead screw nut of the second electric lead screw.

[0010] The frame is also equipped with two back plate guide rails that are parallel to the second electric lead screw, and the pressure head mounting back plate is fixedly connected to the slider of the back plate guide rail.

[0011] The pressure head mounting back plate is vertically mounted with pressure head guide rails corresponding to the positions of each pressure head, and the pressure head mounting bracket for mounting each pressure head is fixedly connected to the slider of the corresponding pressure head guide rail.

[0012] The pressure head mounting back plate has a total of seven pressure heads installed.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] All directions mentioned in this instruction manual are as per the appendix. Figure 1 The directions shown are for reference only and represent relative positional relationships, not absolute positional relationships.

[0019] like Figure 1 As shown, a longitudinally mounted transmission main housing output end parts assembly equipment includes a frame, which includes a base 10, a frame and a protective net surrounding the frame. Since the frame and protective net will obscure part of the equipment structure and affect the accurate representation of the equipment, the frame and protective net are omitted in the figure.

[0020] like Figure 1 and Figure 2 As shown, a first servo press 50 is mounted on the top of the frame. A press head connecting rod 52 is connected to the power output end of the first servo press 50. The lower end of the press head connecting rod 52 has an inverted T-shaped structure, meaning that a circumferentially protruding locking block (not shown in the figure) is provided at the lower end of the press head connecting rod 52. A laterally sliding press head mounting backplate 12 is mounted on the frame below the first servo press 50. Multiple press heads for pressing different parts are mounted side-by-side laterally on the front of the press head mounting backplate 12. Preferably, seven press heads are mounted on the press head mounting backplate 12 in this embodiment. From left to right, the seven press heads are: a positioning pin press head 60, an output shaft oil seal press head 62, a deep groove ball bearing press head 63, a rectangular sealing sleeve retaining ring press head 64, a rectangular sealing sleeve press head 65, a needle roller bearing retaining ring press head 66, and an output shaft needle roller bearing press head. 67 are used for pressing the positioning pin, output shaft oil seal, deep groove ball bearing, rectangular sealing sleeve circlip, rectangular sealing sleeve, needle roller bearing circlip, and output shaft needle roller bearing at the output end of the main housing of the transmission. The arrangement of these seven press heads is based on the assembly sequence of each part, and the number and type of press heads are not limited to the above. The innovation of this utility model lies in the implementation of a press with multiple press heads. The number and type of press heads can be changed according to the needs of the pressed product, and this embodiment does not limit this.

[0021] like Figure 1 and 2 As shown in the diagram, each pressure head is vertically slidably mounted on the pressure head mounting back plate 12 via the pressure head mounting bracket 70. Since the installation method of all seven pressure heads is the same, the following detailed explanation will only take the installation method of the positioning pin pressure head 60 as an example: The pressure head mounting back plate 12 is vertically mounted with a pressure head guide rail 72 corresponding to the position of the positioning pin pressure head 60. The pressure head mounting bracket 70 includes a vertical plate and a horizontal plate that are vertically connected as one piece. The vertical plate is fixedly connected to the slider of the pressure head guide rail 72. The positioning pin pressure head 60 is fixed on the lower side of the horizontal plate. A press connecting block 74 is fixed on the upper side of the horizontal plate. The press connecting block 74 is provided with a connecting rod slot 740 that connects to the pressure head connecting rod 52. In this embodiment, the connecting rod slot 740 is an inverted T-shaped slot that matches the lower end of the pressure head connecting rod 52. The connecting rod slot 740 passes through the press connecting block 74 in the horizontal direction. That is, the left and right sides of the press connecting block 74 are connected by the connecting rod slot 740. From the left and right sides, the connecting rod slot 740 is inverted T-shaped. When the pressure head mounting back plate 12 slides laterally, the lower end of the pressure head connecting rod 52 enters the connecting rod slot 740 from the side of the press connecting block 74. Due to the inverted T-shaped structure of the lower end of the pressure head connecting rod 52 and the connecting rod slot 740, the pressure head connecting rod 52 and the press connecting block 74 are tightly connected together vertically, thereby connecting the pressure head to the first servo press 50. The first servo press 50 drives the pressure head to press the parts onto the main housing of the gearbox. When the first servo press 50 presses down, the pressure head guide rail 72 guides the pressure head, ensuring the straightness of the pressure head sliding vertically, thereby ensuring that the parts can be accurately pressed into the correct position.

[0022] like Figure 1 and Figure 2 As shown, a second electric lead screw 40 is horizontally mounted on the frame. The back of the press head mounting back plate 12 is fixedly connected to the lead screw nut of the second electric lead screw 40. After the second electric lead screw 40 is started, the press head mounting back plate 12 slides horizontally under the drive of the second electric lead screw 40. A back plate guide rail 42 is mounted on the frame above and below the second electric lead screw 40. Both back plate guide rails 42 are parallel to the second electric lead screw 40. The back of the press head mounting back plate 12 is fixedly connected to the slider of the two back plate guide rails 42. The two back plate guide rails 42 can ensure the stability and straightness of the lateral sliding of the press head mounting back plate 12, and ensure that the press head connecting rod 52 and the press connecting block 74 can be smoothly engaged together.

[0023] like Figure 1As shown, a transversely sliding gearbox positioning fixture 30 is mounted on the base 10. A first electric lead screw 20 is also mounted transversely on the base 10. The bottom of the gearbox positioning fixture 30 is fixedly connected to the lead screw nut of the first electric lead screw 20. The gearbox positioning fixture 30 slides transversely under the drive of the first electric lead screw 20. A positioning fixture guide rail 24 is mounted on the front and rear sides of the base 10, respectively. Both positioning fixture guide rails 24 are parallel to the first electric lead screw 20. The bottom of the gearbox positioning fixture 30 is fixedly connected to the sliders of the two positioning fixture guide rails 24. The two positioning fixture guide rails 24 ensure the stability and straightness of the sliding of the gearbox positioning fixture 30. A positioning fixture limiting block 26 is mounted on the base 10 at the left end of the positioning fixture guide rail 24. The positioning fixture limiting block 26 limits the gearbox positioning fixture 30 to prevent it from sliding excessively to the left.

[0024] like Figure 1 As shown, a second servo press 54 is longitudinally mounted on the frame below the press head mounting back plate 12. The output end of the second servo press 54 is connected to a shift oil seal press head 68, which is used to press the shift oil seal located on the side of the main housing of the transmission.

[0025] In summary, the longitudinal gearbox main housing output end parts assembly equipment of this utility model can press eight parts on one machine, integrating the original eight workstations into one, greatly reducing the space occupied. At the same time, it reduces the original eight servo presses to two, reducing the number of servo presses and correspondingly reducing the number of operators, thus greatly reducing the investment cost.

[0026] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
