[0035] like Figure 1-2 As shown, an embodiment of the present invention provides a reverse gear housing processing flip fixture, including a clamping assembly and an adjustment assembly; the clamping assembly includes a panel 10 and a plurality of clamping members 30 for fixing the reverse gear housing 50 and a plurality of support members 40 for supporting the reverse gear housing 50 to ensure its stability during processing, the panel 10 has a plurality of clamping positions, and the plurality of clamping members 30 and the plurality of support members 40 are arranged in a one-to-one correspondence at the plurality of clamping positions, so that each of the clamping members 30 and its corresponding support member 40 fixes the reverse gear housing 50 at the corresponding clamping position; the adjustment assembly includes a base plate 20 located below the panel 10 and rotatably connected to one side end of the panel 10 and a first driving member 21, the first driving member 21 is rotatably arranged on the base plate 20 and its telescopic end is rotatably connected to the panel 10 to drive the panel 10 to rotate relative to the base plate 20, thereby changing the angle of the reverse gear housing 50.

[0036] In an embodiment of the present invention, the reverse gear housing 50 is placed on the clamping position on the panel 10, and then the reverse gear housing 50 is fixed on the clamping position by the clamping member 30 and the support member 40. The clamping member 30 provides clamping force and the support member 40 provides supporting force to ensure the stability of the reverse gear housing 50 during the processing and prevent displacement or vibration during the processing. The combination design of multiple clamping members 30 and multiple support members 40 can simultaneously process multiple reverse gear housings 50, thereby improving production efficiency, and the telescopic end of the first driving member 21 is rotatably connected to the panel 10. The panel 10 can be driven to rotate relative to the base plate 20 by controlling the first driving member 21, thereby adjusting the processing angle of the reverse gear housing 50 to meet the processing requirements of different holes without the need for secondary disassembly and positioning.

[0037] Specifically, such as Figure 2 As shown, in the embodiment of the present utility model, the support member 40 includes a positioning column 41 provided on the panel 10 and two positioning blocks 42 provided on both sides of the positioning column 41. The positioning column 41 is used to support the lower opening of the reverse gear housing 50, and the two positioning blocks 42 are used to support the two mounting seats 53 at the bottom of the reverse gear housing 50. The positioning column 41 and the positioning blocks 42 can ensure that the reverse gear housing 50 is stably fixed on the support member 40, so as to improve the stability and accuracy when machining the hole.

[0038] Based on the above scheme, if Figure 2 As shown, in the embodiment of the present utility model, a positioning pin 43 is provided on the positioning block 42, which is used to locate the mounting hole 54 on the bottom mounting seat 53 of the reverse gear housing 50. The positioning pin 43 is inserted into the mounting hole 54 of the bottom mounting seat 53 of the reverse gear housing 50 to ensure that the reverse gear housing 50 will not shift in a fixed position, thereby improving the processing accuracy. At the same time, each time the reverse gear housing 50 is installed, the positioning pin 43 can ensure that the housing is always in the same position, thereby improving the repeatability of the processing and reducing human errors. The positioning pin 43 can be set accordingly to correspond to the number of mounting holes 54 to achieve rapid positioning of the reverse gear housing 50 parts.

[0039] Specifically, such as Figure 3As shown, in an embodiment of the present invention, the clamping member 30 includes a second driving member 31 provided at the bottom of the panel 10, a fixed rod 32 and a pull rod 33 provided on the panel 10, and a clamping arm 34 that is rotatably provided on the fixed rod 32 in the middle. The telescopic end of the second driving member 31 is connected to the pull rod 33, one end of the clamping arm 34 is rotatably connected to the pull rod 33, and the other end is used to press the reverse gear housing 50 on the positioning block 42. When the telescopic end of the second driving member 31 is extended and retracted, the pull rod 33 is driven to move, and the movement of the pull rod 33 is transmitted to the clamping arm 34 through the rotating connection point, so that the clamping arm 34 rotates around the fixed rod 32, and the other end of the clamping arm 34 presses the reverse gear housing 50 on the positioning block 42 to ensure that the reverse gear housing 50 is firmly fixed in the clamping position to prevent displacement or vibration during processing.

[0040] In an embodiment of the utility model, the first driving member 21 and the second driving member 31 both adopt linear mechanisms such as mature air cylinders, oil cylinders or electric cylinders in the prior art that can realize telescopic functions. No restrictions are made in the description of this embodiment, and the first driving member 21 and the second driving member 31 can both be electrically connected to a conventional PLC controller or single-chip microcomputer to realize automatic control.

[0041] Specifically, such as Figure 4 As shown, in an embodiment of the present invention, a bearing seat 22 is provided on the top of the base plate 20, and the bearing seat 22 is rotatably connected to the connecting shaft 11. The connecting shaft 11 is fixed with a connecting seat 12, and the connecting seat 12 is provided at the bottom of the panel 10. The design of the bearing seat 22 and the connecting shaft 11 ensures that the panel 10 can rotate smoothly relative to the base plate 20, thereby improving stability during processing.

[0042] Based on the above scheme, if Figure 4 As shown, in an embodiment of the present utility model, a first limit block 23 is fixedly provided on the connecting shaft 11, and a first buffer rod 25 is provided on the base plate 20 through a first fixing seat 24, so that the first buffer rod 25 can be installed and disassembled through the first fixing seat 24, and the first limit block 23 can abut against the telescopic end of the first buffer rod 25. The first limit block 23 on the connecting shaft 11 moves with the rotation of the panel 10. When the first limit block 23 abuts against the telescopic end of the first buffer rod 25, the first limit block 23 limits the rotation angle of the panel 10 to prevent damage caused by excessive rotation. At the same time, the telescopic end of the first buffer rod 25 provides a buffering effect, reduces impact and vibration, and protects the tooling and the reverse gear housing 50.

[0043] Specifically, such as Figure 4As shown, the side where the first limit block 23 contacts the first buffer rod 25 is an arc-shaped structure. The arc-shaped structure makes the contact between the first limit block 23 and the first buffer rod 25 smoother and more uniform, further reducing impact and vibration.

[0044] Based on the above scheme, if Figure 3 As shown, in an embodiment of the present utility model, a limit seat 26 is provided on the side of the base plate 20 away from the rotating end, and a second buffer rod 14 is provided on the panel 10 through the second fixed seat 13, so that the second buffer rod 14 can be installed and disassembled through the second fixed seat 13, and the telescopic end of the second buffer rod 14 can abut against the limit seat 26. The second buffer rod 14 on the panel 10 moves as the panel 10 rotates. When the telescopic end of the second buffer rod 14 abuts against the limit seat 26, the maximum rotation angle of the panel 10 is further limited, and additional buffering effect is provided.

[0045] In the embodiment of the present invention, the first buffer rod 25 and the second buffer rod 14 are located at the outermost rod body, and the rod body located at the innermost layer is the inner rod. The outer rod is slidably connected to the inner rod, and a spring can be installed on the inner rod to give it a buffering effect.

[0046] Based on the above scheme, if Figure 3 As shown, in an embodiment of the present invention, a support seat 27 is provided on the top of the base plate 20 away from the rotating end of the panel 10, and a support pin 28 is provided on the support seat 27. The bottom of the panel 10 is provided with a pad 15 corresponding to the support pin 28 and can abut against the support pin 28. When the panel 10 is rotated to a certain angle, the pad 15 at the bottom of the panel 10 will abut against the support pin 28 on the support seat 27, providing additional support to ensure the stability of the panel 10.

[0047] Based on the above scheme, if Figure 4 As shown, in an embodiment of the present utility model, a limit plate 16 is provided on one side of the panel 10 near its rotating end, a rubber pad 17 is provided at the bottom of the limit plate 16, and a second limit block 29 is provided on the bottom plate 20. The rubber pad 17 can abut against the second limit block 29. When the panel 10 rotates to the minimum angle, the rubber pad 17 at the bottom of the limit plate 16 will abut against the second limit block 29 on the bottom plate 20 to limit the rotation angle of the panel 10 and provide buffering and protection. The limit plate 16 can be set to 45, 60 or 75 degrees depending on the product.

[0048] It should be noted that in the embodiments of the present invention, the specific connection methods of each component are connected by conventional means such as bolts, rivets, welding, etc. that are mature in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connections all adopt conventional connection methods in the existing technology, which will not be described in detail here.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not a barrier. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
