DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention. Embodiment 1

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a flipping device of the present invention comprises: frame; The flip assembly 1 includes a support 11 and a flip frame 12. The support 11 is provided with two and symmetrically connected to the frame. The flip frame 12 includes a bottom plate 121 and two side plates 122 vertically connected to the bottom plate 121. The two side plates 122 are parallel to each other and a rotating shaft 123 is vertically connected to the side of the two side plates 122 that are away from each other. The two rotating shafts 123 are coaxial and rotatably connected to the two supports 11 respectively. The clamping assembly 2 includes a load-bearing sliding plate 21, a connecting sliding plate 22, a clamping plate 23 and a telescopic driving source 24. The load-bearing sliding plate 21 and the connecting sliding plate 22 are arranged in parallel in a direction perpendicular to the side plate 122 and are slidably connected to the bottom plate 121. The clamping plate 23 is vertically arranged on the connecting sliding plate 22 and parallel to the side plate 122. The telescopic driving source 24 is connected to the bottom plate 121 to drive the connecting sliding plate 22 to slide. The driving assembly 3 includes a rotation driving source 31, a driving gear 32 and a driven gear 33. The rotation driving source 31 is mounted on the frame. The output end of the rotation driving source 31 is connected to the driving gear 32. The driving gear 32 is meshed with the driven gear 33 connected to any rotating shaft 123. The angle sensing component 4 includes a sensing block 41 and a position sensor 42. The sensing block 41 is vertically connected to the side of any rotating shaft 123 and rotates therewith. A plurality of position sensors 42 are provided. The plurality of position sensors 42 are respectively connected to the support 11 close to the sensing block 41, and the position sensors 42 are all located on the rotation path of the sensing block 41.

[0021] Specifically, the telescopic driving source 24 can drive the connecting sliding plate 22 and the clamping plate 23 thereon to slide in a direction perpendicular to the side plate 122, so that the gearbox placed on the bearing sliding plate 21 is clamped between the clamping plate 23 and a side plate 122; then the driving component 3 can drive the flip frame 12 to flip at a predetermined angle on the frame, so that the input shaft of the gearbox can be docked with the motor spline hole at a predetermined angle; in the process of driving the gearbox to flip, the cooperation between the induction block 41 and the position sensor 42 is used to monitor and determine whether the gearbox is flipped in place, so as to ensure the accuracy of the flipping action. In this way, the automatic flipping of the gearbox at a predetermined angle can be realized through the flipping device, the difficulty of assembly is low, the assembly efficiency is high, and the safety of the assembly process is also improved.

[0022] Reference Figure 3 As shown, further, a through groove extending along the sliding direction of the bearing sliding plate 21 / connecting sliding plate 22 is provided on the bottom plate 121, and a mounting seat 25 is movably connected on one side of the bottom plate 121 away from the bearing sliding plate 21 / connecting sliding plate 22, and the tailstock of the telescopic driving source 24 is connected to the mounting seat 25, and a connecting plate 26 is provided at the output end of the telescopic driving source 24, and the connecting plate 26 passes through the through groove and is connected to the connecting sliding plate 22. Specifically, during the clamping process of the clamping assembly 2, the telescopic driving source 24 drives the connecting sliding plate 22 and the clamping plate 23 thereon to slide toward the bearing sliding plate 21, and when the clamping plate 23 contacts the gearbox placed on the bearing sliding plate 21, the gearbox and the bearing sliding plate 21 are pushed to move toward the side plate 122, and finally the gearbox is clamped between the clamping plate 23 and the side plate 122. It can be imagined that the clamping assembly 2 can be applied to the clamping of a variety of gearboxes with different widths, and has high versatility. Specifically, the telescopic driving source 24 can be an oil cylinder, and the rotating driving source 31 can be a motor.

[0023] Reference Figure 2 and Figure 3 As shown, further, a first protective plate 27 is parallelly connected to a surface of the bearing sliding plate 21 away from the bottom plate 121 , and one end of the first protective plate 27 is vertically connected to a limiting plate 28 .

[0024] Furthermore, a second protective plate 29 is provided on the opposite surface of the side plate 122 and the clamping plate 23 of the bearing sliding plate 21 away from the side connected to the sliding plate 22. It can be imagined that the first protective plate 27 and the second protective plate 29 are both made of relatively wear-resistant materials, which can prevent the product from directly contacting and rubbing with the bearing sliding plate 21, the clamping plate 23 and the side plate 122, thereby increasing the service life of the components and reducing the maintenance cost of the equipment.

[0025] Furthermore, a plurality of slide rails are provided on the bottom plate 121 and are parallel to each other and extend in a direction perpendicular to the side plates 122 . The supporting slide plate 21 and the connecting slide plate 22 are respectively slidably connected to the slide rails through sliders.

[0026] Furthermore, the two supports 11 are coaxially provided with shaft holes, and the two supports 11 are both provided with bearing seats 13 coaxial with the shaft holes, and the two rotating shafts 123 respectively pass through the two shaft holes and are rotatably connected to the two bearing seats 13 through bearings. Specifically, the two bearing seats 13 are respectively connected to the mutually opposite sides of the two supports 11 through fasteners, and the two rotating shafts 123 respectively pass through the two shaft holes and are rotatably connected to the bearing seats 13; and one of the two rotating shafts 123 extends a certain length out of the bearing seat 13 to facilitate the installation of the driven gear 33.

[0027] Reference Figure 4 As shown, further, a limiting sleeve 14 is coaxially arranged on any rotating shaft 123, a limiting protrusion 141 is vertically extended on the side of the limiting sleeve 14, a limiting block 15 is arranged on the support 11 and is located on the rotation path of the limiting protrusion 141, and a buffer 151 is arranged on the limiting block 15. Specifically, two limiting blocks 15 are arranged on the support 11, and the sensing block 41 rotates between the two limiting blocks 15 along with the rotating shaft 123. The two limiting blocks 15 correspond to the initial position (i.e., horizontal state) and the position of the maximum rotation angle (flipped 90 degrees) of the flip frame 12, respectively. The two limiting blocks 15 can play a role of limiting in the process of the flip frame 12 rotating, and reduce the shaking amplitude of the motor and the flip frame 12 when they stop rotating; at the same time, a buffer 151 is also arranged on the limiting block 15 to play a buffering role.

[0028] Reference Figure 1 and Figure 2 As shown, further, a first rib plate is connected between the two side plates 122, and a plurality of second rib plates are respectively connected between the two side plates 122 and the bottom plate 121, so as to increase the strength and stability of the entire structure.

[0029] Further, the position sensors 42 are respectively mounted on a mounting frame, and the mounting frame is connected to the support 11 through a fastener. Specifically, the position sensor 42 can be divided into an initial position sensor and a rotation angle sensor, wherein the initial position sensor is a sensor for detecting whether the flip frame 12 is in a horizontal position, and the rotation angle sensor is a sensor for detecting whether the flip frame 12 drives the gearbox to rotate to a predetermined angle, and multiple position sensors 42 at different positions can be set according to actual needs.

[0030] Furthermore, the outer diameter of the driving gear 32 is smaller than the outer diameter of the driven gear 33. It is conceivable that the small-diameter driving gear 32 and the large-diameter driven gear 33 meshing with each other can reduce speed and increase torque, so that the drive assembly 3 can output sufficient torque.

[0031] Working process: In the initial state, the turning frame 12 is in a horizontal state, and the output shaft of the telescopic driving source 24 is in an extended state.

[0032] During assembly, the operator first places the gearbox to be assembled on the load-bearing sliding plate 21, and then controls the output shaft of the telescopic driving source 24 to retract and drive the connecting sliding plate 22 and the clamping plate 23 thereon to move toward the load-bearing sliding plate 21, so that the gearbox is finally clamped between the clamping plate 23 and the side plate 122. After clamping in place, start the rotating driving source 31. The rotating driving source 31 drives the flipping frame 12, the clamping assembly 2 and the gearbox to flip through the mutually meshing driving gear 32 and the driven gear 33. During the flipping process, the predetermined position sensor 42 will monitor whether the sensing block 41 that rotates synchronously with the rotating shaft 123 is rotated into place. When it is rotated into place, the rotating driving source 31 stops so that the input shaft of the gearbox is at a predetermined installation angle, and then the motor and the gearbox are docked and installed together.

[0033] After the installation is completed, the rotary drive source 31 is started to drive the flip frame 12 and the gearbox thereon to return to a horizontal state, and then the telescopic drive source 24 drives the connected sliding plate 22 to return to a state, release the product and lift it out.

[0034] During the above working process, when the clamping assembly 2 clamps the gearbox, the action sensor of the telescopic driving source 24 detects whether the clamping is in place. Only after the clamping is in place can the flipping assembly 1 perform the flipping action, thereby ensuring the safe production. Embodiment 2

[0035] On the basis of the first embodiment, a plurality of first fastening holes can be provided on the clamping plate 23 and the side plate 122 for clamping the product, and a plurality of second fastening holes corresponding to the first fastening holes can be provided on the two second protective plates 29. When the telescopic drive source 24 drives the clamping plate 23 to clamp the gearbox between the clamping plate 23 and the side plate 122, the gearbox can be fixed for a second time through each group of coaxial first fastening holes and second fastening holes and fasteners, further improving the stability of the gearbox and ensuring the safety of the flipping process. Preferably, a wear-resistant plate can be provided on the clamping plate 23 and the side plate 122 respectively, so that when the bolts are installed, the bolts can be prevented from directly rubbing against the side plate 122 and the clamping plate 23, thereby improving the service life of the parts. Embodiment 3

[0036] The present invention also discloses a production line, comprising the turning device as described in the first embodiment.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
