[0038] Refer toFigure 2 and Figure 3 In an embodiment of the present application, the angle grinder automatic mounting device comprises a workbench 1, a gear pushing device 2 and a nut pushing device 3 mounted on the workbench 1, a first storage device 4 for storing gears, a second storage device 5 for storing nuts, a screwing clamping device 6, and an assembly table 7 for carrying a gear box (see Figure 4 ). The above structures can be mounted in a frame.

[0039] Referring to Figure 4 and Figure 5 , the assembly table 7 can be controlled to switch between a first assembly position and a second assembly position. In this embodiment, the assembly table 7 can be controlled to move along a preset straight line direction to the first assembly position or the second assembly position. The assembly table 7 can be switched between the first assembly position and the second assembly position by cooperating with a mounting cylinder on the workbench 1. In this embodiment, the preset straight line direction is the straight line direction corresponding to the X arrow in Figure 5 .

[0040] When the assembly table 7 is located at the first assembly position (as shown in Figure 4 ), the gear pushing device 2 is used to cooperate with the first storage device 4 to push the gears to the first predetermined position of the gear box on the assembly table 7.

[0041] When the assembly table 7 is located at the second assembly position (as shown in Figure 5 ), the nut pushing device 3 is used to carry the nuts in the second storage device 5 and can cooperate to move the nuts to the second predetermined position of the gear box on the assembly table 7; the screwing clamping device 6 is used to drive the rotor to rotate to assemble the gear box, the gears located at the first predetermined position, and the nuts located at the second predetermined position.

In this embodiment, the shape of the barrel 43 can be specifically arranged according to different design requirements.

[0044] It can be understood that, in other embodiments, the first storage device 4 and the second storage device 5 can also be arranged as a vibrating disc to arrange the gears and nuts in order. By arranging the discharging end of the vibrating disc to cooperate with the gear pushing device 2 or the nut pushing device 3, the gears and nuts can be pushed one by one.

In this embodiment, when the gear pushing member 22 drives the gear positioning plate 21 to return, the first storage device 4 can correspondingly convey a gear into the positioning hole 211, so as to facilitate the assembly of the next angle grinder. In this embodiment, the gear pushing member 22 can be selected from a gas cylinder, a hydraulic cylinder and the like.

[0046] Referring to Figure 5 , in this embodiment, the nut pushing device 3 comprises a nut pushing assembly 31 and a nut clamping assembly 32, when the assembly table 7 is located at the first assembly position, the nut pushing assembly 31 can push the nut to the clamping end of the nut clamping assembly 32; when the assembly table 7 is located at the second assembly position, the nut clamping assembly 32 can drive the nut to move to the second predetermined position of the gear box.

[0047] Referring to Figure 7 , the nut clamping assembly 32 comprises a pushing driving member 321 and a clamping plate 322, the clamping plate 322 is provided with a clamping opening 323, and a suction member for fixing the nut is arranged on the peripheral wall of the clamping opening 323.

[0048] When the assembling table 7 is located at the first assembling position, the nut pushing assembly 31 can be driven to move to the clamping opening 323 (as shown in Figure 7 When the assembling table 7 is located at the second assembling position, the pushing driving member 321 can drive the clamping opening 323 to move to the second predetermined position of the gear box.

[0049] Referring to Figure 7 and Figure 8 , the nut pushing assembly 31 comprises a base plate 311 which can be driven to move close to or away from the clamping plate 322, a nut positioning plate 312 mounted on the base plate 311 and a nut pushing member 314. Wherein, the workbench 1 can be equipped with a mounting cylinder to drive the base plate 311 to move.

[0050] The nut positioning plate 312 is provided with a channel 313 capable of accommodating the nut, and the distal end of the barrel 43 away from the rod 42 corresponds to the channel 313; as shown in Figure 7 When the base plate 311 is driven to move to abut against the clamping plate 322, the nut pushing member 314 can push the nut in the channel 313 to move to the clamping opening 323. At this time, the clamping opening 323 can adsorb and fix the nut through the adsorption member. When the assembling table 7 moves to the second assembling position, the pushing driving member 321 drives the clamping plate 322 to move, so that the nut is matched to the second predetermined position of the gear box.

[0051] Referring to Figure 5 , the gear pushing device 2 and the nut clamping assembly 32 are located on the same side of the preset straight line direction, and the nut pushing assembly 31 and the nut clamping assembly 32 are located on both sides of the preset straight line direction. The above layout can effectively cooperate with the first assembling position and the second assembling position of the assembling table 7 to efficiently complete the assembly of the parts of the angle grinder.

[0052] Referring to Figure 3 and Figure 4 , in this embodiment, the angle grinder automatic mounting equipment further comprises a gear box pushing device 8 mounted on the assembling table 7, the gear box pushing device 8 comprises a pressing driving member 81 mounted on the assembling table 7 and an abutting plate 82 mounted on the output end of the pressing driving member 81, and the assembling table 7 and the abutting plate 82 cooperatively form a mounting space of the gear box, and the pressing driving member 81 can drive the abutting plate 82 to press the gear box. The pressing driving member 81 can be selected from a cylinder, a hydraulic cylinder and the like. By pressing and fixing the gear box, the shaking of the gear box when switching between the first assembling position and the second assembling position can be avoided, and the subsequent assembly with the rotor is facilitated, so that the assembly precision and the assembly efficiency can be effectively improved.

[0053] Referring to Figure 6 , the workbench 1 is provided with an avoiding hole 11. Combined with Figure 3The screw clamping device 6 is installed on one side of the workbench 1 and is arranged in cooperation with the avoiding hole 11.

The screw clamping device 6 can further be provided with an optical axis 63 to limit the movement direction of the rotating driving part 61 and ensure assembly accuracy. In the embodiment, the rotating driving part 61 can be a rotating servo motor.

[0055] The operation process of the angle grinder automatic mounting equipment of the present application is as follows:

[0056] First, the gear box is pre-installed on the assembly table 7, and the rotor is installed in the clamping jaw 62. When the equipment is operated, the assembly table 7 is first driven to the first assembly position. At this time, the gear pushing device 2 cooperates with the first storage device 4 to push the gear to the first predetermined position of the gear box. At the same time, the nut pushing assembly 31 moves to a position cooperating with the nut clamping assembly 32, and pushes the nut to the clamping end of the nut clamping assembly 32.

[0057] Subsequently, the nut pushing assembly 31 is reset synchronously during the process that the assembly table 7 is driven to the second assembly position. When the assembly table 7 reaches the second assembly position, the nut clamping assembly 32 drives the nut to move to the second predetermined position of the gear box. Finally, the screw clamping device 6 drives the rotor to rotate, realizing the assembly of the rotor, the gear located at the first predetermined position, and the nut located at the second predetermined position.

[0058] Since the equipment can realize automatic feeding of the gear and the nut, without the need for additional manual operation, the assembly efficiency of the angle grinder is effectively improved.
