In order not to damage the front gearbox and the rear gearbox, the assembly of the front gearbox and the rear gearbox is done manually, which requires a lot of manpower and wastes a lot of time.

[0003] Therefore, a new device is urgently needed to solve the above problems. Utility Model Content

[0004] In view of this, the present invention provides a front and rear box assembly device, wherein the first driving structure in the front and rear box assembly device can drive the second workpiece to rotate, ensuring that the bushing in the second workpiece and the spline shaft of the first workpiece are aligned and connected, so as to improve the assembly efficiency of the first workpiece and the second workpiece.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] The front and rear box assembly device provided in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0039] Figure 1 This is a structural schematic diagram of the front and rear box assembly device provided in an embodiment of the present utility model. Figure 2 This is a schematic diagram of a machine component in the front and rear box assembly device provided in an embodiment of the present utility model. Figure 3 This is a schematic diagram of the structure of the first slide assembly in the front and rear box assembly device provided in an embodiment of the present utility model. Figure 1 The X direction is the first direction, and the Y direction is the second direction. (Refer to...) Figure 1 , Figure 2 and Figure 3 The front and rear box assembly device provided in this embodiment of the utility model includes a machine base assembly 10, a first slide assembly 20, a second slide assembly 30, a positioning assembly 40, and a transmission assembly 50. The machine base assembly 10 may include a first machine base 11 and a second machine base 12, with the second machine base 12 and the first slide assembly 20 sequentially disposed on the first machine base 11. The first slide assembly 20 is reciprocating relative to the first machine base 11 along a first direction and is used to mount a first workpiece, which may be the rear box of a gearbox or other components to be assembled.

[0040] The positioning assembly 40 and the second slide assembly 30 are both disposed on the side of the second machine base 12 opposite to the first machine base 11, with the positioning assembly 40 located between the second slide assembly 30 and the first slide assembly 20. The positioning assembly 40 is used to mount a second workpiece, which may be the front housing of a gearbox or other components to be assembled. The first workpiece has at least one splined shaft on the side facing the second machine base 12, and the second workpiece has at least one bushing on the side facing the first slide assembly 20. The bushing has an internal spline for engaging with the splined shaft.

[0041] The second slide assembly 30 includes a sliding housing 31 and a first drive structure 32. The first drive structure 32 is disposed on the sliding housing 31, which is disposed on the second machine tool 12. The sliding housing 31 can reciprocate relative to the second machine tool 12 in a first direction. The output end of the first drive structure 32 is connected to one end of the transmission assembly 50, and the other end of the transmission assembly 50 is connected to the end of the second workpiece away from the first sliding assembly. The first drive structure 32 drives the second workpiece to rotate through the transmission assembly 50, so that at least one bushing on the second workpiece is aligned and connected with at least one spline shaft.

[0042] In this embodiment, when the first workpiece and the second workpiece need to be assembled, the first workpiece can be placed on the first slide assembly 20, and the second workpiece can be placed on the positioning assembly 40. The first workpiece can move towards the positioning assembly 40 along with the first slide assembly 20. During the movement of the first workpiece, the first drive structure 32 drives the second workpiece placed on the positioning assembly 40 to rotate through the transmission assembly 50, so that the internal spline of the bushing on the second workpiece engages with the spline shaft on the first workpiece, completing the assembly of the first and second workpieces. During this process, the second workpiece can be driven by the first drive structure 32, so that the bushing in the second workpiece is in a rotating state, which facilitates the insertion of the spline shaft into the internal spline of the bushing, thereby reducing the use of manual labor, improving the assembly efficiency of the first and second workpieces, and the rotation of the second workpiece can also reduce the damage to the first and / or second workpieces during assembly.

[0043] Furthermore, the first slide assembly 20 can reciprocate relative to the first machine base 11 along a first direction, so that when the first workpiece is mounted on the first slide assembly 20, the first slide assembly 20 is moved away from the positioning assembly 40, preventing interference between the first workpiece and the positioning assembly 40, as well as the second workpiece on the positioning assembly 40. Similarly, the sliding housing 31 can reciprocate relative to the second machine base 12 along a first direction. When the first workpiece and the second workpiece are assembled, the sliding housing 31 moves towards the side closer to the positioning assembly 40. When the first workpiece and the second workpiece are assembled, the sliding housing 31 moves away from the side away from the positioning assembly 40, so that the transmission assembly 50 is disengaged from the second workpiece.

[0044] The machine tool assembly 10 also includes a second drive structure 13, a mounting base 16, a first connecting plate 131, a first guide structure 14, a second guide structure 15, and a first baffle 17. The first guide structure 14 is disposed on the first machine tool 11, and the second guide structure 15 and the first baffle 17 are disposed on the second machine tool 12. The first guide structure 14 includes two first guide rails 140 extending along a first direction, which are arranged in parallel. Each first guide rail 140 is provided with at least one first slider 141, which is used to be fixedly connected to the first slide assembly 20. The second drive structure 13 is fixed to the first machine tool 11, and the output end of the second drive structure 13 can be connected to the first slide assembly 20. The second drive structure 13 drives the first slide assembly 20 to reciprocate along the first direction on the first guide rails 140, so that the first workpiece on the first slide assembly 20 moves towards or away from the positioning component 40 to complete the assembly of the first workpiece and the second workpiece. The second drive structure 13 may include a first drive cylinder 130 and a first connecting plate 131. The first drive cylinder 130 is fixed on the first machine base 11 by a mounting base 16. The output end of the first drive cylinder 130 is connected to a first baffle 17. The first baffle 17 is connected to a first slide assembly 20. The first drive cylinder 130 drives the first slide assembly 20 to reciprocate along a first direction through the first baffle 17.

[0045] The second guide structure 15 includes two second guide rails 150, which extend along a first direction and are arranged in parallel. Each second guide rail 150 is provided with at least one second slider 151, which is used to be fixedly connected to the second slide assembly 30. The output end of the third drive structure 60 can be connected to the second slide assembly 30. The third drive structure 60 can drive the second slide assembly 30 to reciprocate along the first direction on the second guide rails 150, so as to connect or separate the transmission assembly 50 from the second workpiece.

[0046] Continue to refer to Figure 1 , Figure 2 and Figure 3The first slide assembly 20 includes a first slide plate 21, a first lifting structure 22, a first mounting plate 23, two first brackets 24, a guide structure 27, a first photoelectric switch 25, and a first proximity switch 26. The first lifting structure 22 is disposed on the first slide plate 21, and multiple guide structures 27 are provided between the first surface of the first slide plate 21 and the first mounting plate 23. The guide structures 27 can improve the stability of the first mounting plate 23 mounted on the first slide plate 21. The first lifting structure 22 is disposed on the first slide plate 21, and the number of first lifting structures 22 can be one or two. The first slide plate 21 is also used to connect with the first slider 141 so that the first slide plate 21 can move along the extension direction of the first guide rail 140. The two first brackets 24 are disposed on the side of the first mounting plate 23 away from the first slide plate 21, and the two first brackets 24 are spaced apart, forming a space for mounting the first workpiece between the two first brackets 24 and the first mounting plate 23. On the side of the first bracket 24 away from the first mounting plate 23, a plurality of first fixtures 28 may be provided. Each first fixture 28 may be provided with a plurality of U-shaped mounting grooves, and the depth of each U-shaped mounting groove may be different, so that the first bracket 24 can be used for different first lifting tools. Different first lifting tools can lift different first workpieces, thereby improving the applicability of the front and rear box assembly device.

[0047] It is worth mentioning that the first support 24 may have an opening, and a first photoelectric switch 25 may be installed at the opening of the first support 24. The first photoelectric switch 25 can be used to detect whether a first workpiece is installed in the first slide assembly 20. A first proximity switch 26 may also be installed on one side of each first tooling 28. The first proximity switch 26 can be used to detect whether the installation position of the first lifting device is correct, thereby improving the efficiency of assembling the first workpiece and the second workpiece.

The third guide structure 34 includes two third guide rails 340, which are fixedly mounted on the first plate 310 of the sliding box 31. The third guide rails 340 extend along a second direction, which is perpendicular to the first direction. Each third guide rail 340 is provided with at least one third slider 341. The second slide plate 38 is connected to the third slider 341. The second lifting structure 33 is connected to the second slide plate 38 to drive the second slide plate 38 to reciprocate along the second direction. The second lifting structure 33 includes a lifting bracket 332, a lifting block 330, and a worm gear screw jack. The lifting bracket 332 is fixed on the first plate 310. One end of the worm gear screw jack 331 is fixed on the lifting bracket 332, and the other end of the worm gear screw jack is connected to the lifting block 330. The lifting block 330 is connected to the second slide plate 38. The worm gear screw jack 331 drives the lifting block 330 to reciprocate along the second direction. The lifting block 330 drives the second slide plate 38 to reciprocate along the second direction on the third guide rail 340, thereby driving the first driving structure 32 to reciprocate along the second direction, so that the transmission component 50 can be aligned and connected with the second workpiece after being connected to the connecting sleeve 36.

[0049] A second proximity switch 39 is also provided on the side of the first plate 310 facing the positioning component 40.

[0050] The second plate 311 is connected to the second slider 151. The second plate 311 is also provided with a second connecting plate 37, which is used to connect the cable chain. The third connecting plate 67 in the third drive structure 60 is connected to the second plate 311 to drive the second slide assembly 30 to reciprocate along the first direction on the second guide rail 150, so that the second slide assembly 30 moves closer to or further away from the positioning assembly 40, thereby realizing that the first drive structure 32 drives the second workpiece to rotate and can disengage the second slide assembly 30 from the second workpiece.
