[0051] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0052] The present invention discloses an automatic assembly machine for producing a steering gear briquette, wherein the steering gear briquette has a briquette body 1, a diaphragm 2 and a sealing ring 3. The automatic assembly machine comprises: a machine platform 4, on which a rotating disk 5 is arranged, and on which a plurality of positioning seats 6 are arranged, and the plurality of positioning seats 6 are arranged along the circumferential direction of the rotating disk 5; a body loading assembly 7, which is arranged on the machine platform 4 and is located on the side of the rotating disk 5, and the body loading assembly 7 is used to transport the briquette body 1 to be assembled to the positioning seat 6; a detection assembly 8, which is arranged on the machine platform 4 and is located on one side of the body loading assembly 7, and the detection assembly 8 is used to detect the briquette body 1; a diaphragm loading assembly 9, which is arranged on the machine platform 4 and is located on one side of the detection assembly 8, and the diaphragm loading assembly 9 is used to assemble the diaphragm 2 Installed on the block body 1; the sealing ring feeding component 10 is arranged on the machine table 4 and is on one side of the diaphragm feeding component 9, and the sealing ring feeding component 10 has: a sealing ring positioning platform 11, which is used to position the sealing ring 3 to be assembled; a stretching member 12, which is connected to the side of the sealing ring positioning platform 11 and is used to stretch the sealing ring 3; a sealing ring picking member 13, which is movably arranged above the machine table 4, and the sealing ring picking member 13 has a first picking state and a second picking state. The first picking state is used to adsorb the sealing ring 3 on the sealing ring positioning platform 11 and transport it to the stretching member 12, and the second picking state is used to make the sealing ring 3 after the stretching member 12 is stretched out be set on the outside of the sealing ring picking member 13, and assemble it on the block body 1.

[0053] Based on the above embodiments, an exemplary structure of this solution is as follows: Figures 2 to 7 As shown. Among them, the positioning seat 6 preferably adopts a three-jaw chuck. A conveyor belt for driving the movement of the tray is provided on the machine table 4; the block body 1 is placed on the conveyor belt through the tray and is located below the body feeding assembly 7. A motor for driving the rotating disk 5 to rotate is also provided on the machine table 4. When working, the body feeding assembly 7 first transports the block bodies 1 in the tray to the positioning seat 6 one by one. A sensor electrically connected to the motor is provided on the positioning seat 6. When the sensor detects that the block body 1 is placed on the positioning seat 6, it will transmit this information to the motor, so that the motor drives the rotating disk 5 to rotate. After the rotating disk 5 drives the block body 1 to rotate below the detection assembly 8, the detection assembly 8 detects the block body 1. Subsequently, the rotating disk 5 continues to drive the block body 1 to rotate and transport it to the bottom of the diaphragm feeding assembly 9, and the diaphragm feeding assembly 9 presses the diaphragm 2 into the block body 1. Then, the rotating disk 5 continues to drive the block body 1 equipped with the diaphragm 2 to rotate, so that it moves to the bottom of the sealing ring feeding assembly 10.

[0054] Before the diaphragm 2 is pressed into the block body 1, the sealing ring picking member 13 is in the first picking state, that is, it absorbs the sealing ring 3 on the sealing ring positioning platform 11 and transports it to the stretching member 12. Subsequently, the stretching member 12 stretches the sealing ring 3 and makes it sleeved on the outside of the sealing ring picking member 13. After the diaphragm 2 is pressed into the block body 1 and the rotating disk 5 moves the two to the bottom of the sealing ring feeding assembly, the sealing ring picking member 13 switches to the second picking state and installs the sealing ring 3 on the block body 1, thereby completing the automatic assembly process of the steering gear block.

[0055] In this solution, through the mutual cooperation between the rotating disk 5, the main body feeding assembly 7, the detection assembly 8, the diaphragm feeding assembly 9 and the sealing ring feeding assembly 10, the assembly of the steering gear pressure block can be automatically completed, the assembly efficiency of the steering gear pressure block can be improved, the production needs of large quantities of steering gear pressure blocks can be met, and the assembly accuracy can be improved.

[0056] The stretching member 12 includes: a first support frame 14, which is connected to the machine table 4; at least three first driving members 15, at least three first driving members 15 are distributed in an annular manner on the first support frame 14; a stretching rod 16, each first driving member 15 is connected to a stretching rod 16, and the stretching rod 16 is used to stretch the sealing ring 3 mounted thereon.

[0057] The first driving member 15 can be a cylinder, a motor or a linear guide. In this scheme, four first driving members 15 are preferably used. Before the sealing ring picking member 13 adsorbs the sealing ring 3 on the sealing ring positioning platform 11, the four first driving members 15 drive the four stretching rods 16 to approach each other. After the sealing ring picking member 13 absorbs the sealing ring 3 on the sealing ring positioning platform 11, the sealing ring 3 is moved to the outside of the four stretching rods 16, and then the first driving member 15 drives the four stretching rods 16 to move away from each other, so that the sealing ring 3 is separated from the sealing ring picking member 13 and the sealing ring 3 is stretched. Afterwards, the sealing ring picking member 13 moves downward relative to the stretching member 12, and then the first driving member 15 drives the four stretching rods 16 to approach each other, at which time, the sealing ring 3 shrinks and is fixed on the outer side wall of the sealing ring picking member 13.

[0058] The end of the sealing ring feeding member 13 is provided with a feeding groove 17 and a gas channel connected to the feeding groove 17 at one end. The feeding groove 17 is adapted to the shape of the sealing ring 3. After the gas is passed through the gas channel, the sealing ring 3 is adsorbed in the feeding groove 17.

[0059] The gas channel is used to connect the gas source. After the sealing ring picking member 13 moves to the top of the sealing ring positioning platform 11, the sealing ring picking member 13 descends relative to the sealing ring positioning platform 11, so that the sealing ring 3 abuts against the picking groove 17. At this time, under the action of the gas source, the sealing ring 3 is adsorbed in the picking groove 17 through the gas channel, so that the sealing ring picking member 13 has the ability to adsorb the sealing ring 3 on the sealing ring positioning platform 11.

[0060] The sealing ring material taking piece 13 is provided with an avoidance groove 18 for the pressing block body 1 to be inserted, and the outer side wall of the sealing ring material taking piece 13 is provided with a through groove 19 penetrating the side wall of the sealing ring material taking piece 13, and the through groove 19 corresponds to the stretching rod 16 one by one.

[0061] After the sealing ring 3 is sleeved on the outside of the sealing ring picking member 13, the sealing ring picking member 13 switches to the second picking state and moves to the top of the block body 1, and then the sealing ring picking member 13 descends relative to the block body 1, so that the upper end of the block body 1 enters the avoidance groove 18, and the lower end of the sealing ring picking member 13 is located at the installation groove of the block body 1 where the sealing ring 3 needs to be assembled. Then the sealing ring loading assembly 10 pushes the sealing ring 3 away from the sealing ring picking member 13, so that the sealing ring 3 is stuck in the installation groove, and the installation of the sealing ring 3 is completed. The through groove 19 on the sealing ring picking member 13 is used to pass through the sealing ring picking member 13 when the four stretching rods 16 move away from and approach each other, so that the stretching member 12 can pull open the sealing ring 3 adsorbed on the sealing ring picking member 13, and can sleeve the pulled sealing ring 3 on the outside of the sealing ring picking member 13.

[0062] The sealing ring feeding assembly 10 also includes: a second support frame 20; a second driving member 21, which is horizontally connected to the second support frame 20; a third driving member 22, which is vertically connected to the output end of the second driving member 21; a moving seat 23, which is connected to the output end of the third driving member 22, and the sealing ring picking member 13 is connected to the moving seat 23; a fourth driving member 24, which is vertically connected to the moving seat 23; a pushing block 25, which is connected to the output end of the fourth driving member 24 and is sleeved on the outside of the sealing ring picking member 13, and is used to push the sealing ring 3 on the outer side wall of the sealing ring picking member 13 away.

[0063] The second driving member 21 is preferably a linear guide rail, the third driving member 22 is preferably a motor, and the fourth driving member 24 is preferably a cylinder. When working, the second driving member 21 drives the third driving member 22 and the moving seat 23 to move left and right, thereby realizing the horizontal movement of the sealing ring picking member 13. The third driving member 22 is used to drive the sealing ring picking member 13 to move in the vertical direction. After the sealing ring picking member 13 moves to the preset position so that the pressing block body 1 is inserted into the avoidance groove 18, the fourth driving member 24 drives the pushing block 25 to move, pushes the sealing ring 3 on the sealing ring picking member 13 away, and sets the sealing ring 3 on the pressing block body 1.

[0064] In this scheme, it also includes a material picking component 26, which is arranged on the machine table 4 and is used to take away the assembled pressing blocks on the positioning seat 6. The material picking component 26 and the main body loading component 7 both include: a third support frame 27; a fifth driving member 28, which is horizontally arranged on the third support frame 27; a sixth driving member 29, which is vertically connected to the output end of the fifth driving member 28; a seventh driving member 30, which is connected to the output end of the sixth driving member 29, and the output end of the seventh driving member 30 is connected to a pneumatic clamp 31, and the seventh driving member 30 is used to drive the pneumatic clamp 31 to rotate.

[0065] The fifth driving member 28 is preferably a linear guide rail, and the sixth driving member 29 and the seventh driving member 30 are both motors. When working, the fifth driving member 28 drives the sixth driving member 29 and the seventh driving member 30 to move in the horizontal direction to achieve the displacement of the block body 1 in the horizontal direction. The block body 1 is placed horizontally on the pallet. On the body feeding assembly 7, after the fifth driving member 28 and the sixth driving member 29 jointly drive the pneumatic clamp 31 to clamp the block body 1, the seventh driving member 30 drives the pneumatic clamp 31 to rotate 90°, so that the block body 1 becomes an upright state. After the steering machine block is assembled, the fifth driving member 28 and the sixth driving member 29 on the picking assembly 26 jointly drive the pneumatic clamp 31 to move to the positioning seat 6, so that the pneumatic clamp 31 can grab the steering machine block on the positioning seat 6, and then move it to the preset position, and the seventh driving member 30 drives the pneumatic clamp 31 to rotate the steering machine block to a horizontal lying state, so that the assembled steering machine block can be arranged on the pallet.

[0066] The detection assembly 8 includes: a fourth support frame 32; an eighth driving member 33, which is horizontally arranged on the fourth support frame 32; a ninth driving member 34, which is vertically connected to the output end of the eighth driving member 33; a detection block 35, which is connected to the output end of the ninth driving member 34, and the end of the detection block 35 away from the ninth driving member 34 is provided with a contoured portion adapted to the end face of the pressing block body 1; a displacement sensor 36, which is connected to the fourth support frame 32, and the displacement sensor 36 is used to detect the distance that the ninth driving member 34 drives the detection block 35 to move.

[0067] The eighth driving member 33 is preferably a linear guide rail, and the ninth driving member 34 is preferably a cylinder. During the assembly process of the steering gear block, the machining accuracy of the end face of the diaphragm 2 pressed on the block body 1 directly affects the assembly accuracy of the steering gear. For this reason, the present scheme is provided with a detection block 35 for detecting the block body 1 on the detection assembly 8. The detection principle is as follows: when the block body 1 is fixed on the positioning seat 6, the lower end of the block body 1 is close to the end face of the positioning seat 6. The detection block 35 is pushed to move in the vertical direction by the ninth driving member 34, so that the contour surface on the detection block 35 can touch the end face of the block body 1. Then, the distance moved by the detection block 35 is detected by the displacement sensor 36, and the distance between the upper end face of the block body 1 where the diaphragm 2 is installed and the bottom of the block body 1 can be calculated. When designing the assembly size of the diaphragm 2 on the block body 1, a certain margin is left. By fine-tuning the assembly position of the diaphragm 2 on the block body 1, the size difference of the block body 1 is compensated, thereby ensuring the assembly accuracy of the steering gear block. For example, when the detection block 35 abuts against the pressing block body 1 and the distance detected by the displacement sensor 36 is 0.1 mm greater than the standard value, the subsequent diaphragm feeding assembly 9 reduces the depth of the diaphragm 2 pressed into the pressing block body 1 by 0.1 mm.

[0068] Specifically, after the rotating disk 5 moves the positioning seat 6 equipped with the pressing block body 1 to the side of the detection assembly 8, the eighth driving member 33 drives the ninth driving member 34 to move horizontally, thereby driving the detection block 35 to move above the pressing block body 1. Then the ninth driving member 34 drives the detection block 35 to move downward, so that the contour surface set at the lower end of the detection block 35 can abut against the end face of the pressing block body 1. At this time, the distance moved by the detection block 35 can be calculated by detecting the displacement sensor 36, and the distance from the end face of the pressing block body 1 where the diaphragm 2 is installed to the lower end of the pressing block body 1.

[0069] The diaphragm loading assembly 9 includes: a diaphragm positioning platform 37, which is used to position the diaphragm 2 to be assembled; a fifth support frame 38, which is located on the side of the diaphragm positioning platform 37; a tenth driving member 39, which is horizontally connected to the fifth support frame 38; an eleventh driving member 40, which is vertically connected to the output end of the tenth driving member 39; an adsorption member 41, which is connected to the output end of the eleventh driving member 40 and is used to adsorb the diaphragm 2 on the diaphragm positioning platform 37.

[0070] The tenth driving member 39 is preferably a linear guide rail, and the eleventh driving member 40 is preferably a motor. When working, the tenth driving member 39 drives the eleventh driving member 40 to move in the horizontal direction, thereby driving the adsorption member 41 to move in the horizontal direction. After the adsorption member 41 moves horizontally to the top of the diaphragm positioning platform 37, the eleventh driving member 40 drives the adsorption member 41 to move in the direction of the diaphragm positioning platform 37, so that the adsorption member 41 rests on the diaphragm 2. Afterwards, the adsorption member 41 adsorbs the diaphragm 2 on the diaphragm positioning platform 37. The tenth driving member 39 and the eleventh driving member 40 work together to drive the adsorption member 41 to move to the top of the positioning seat 6, and then the eleventh driving member 40 drives the adsorption member 41 to descend, so that the diaphragm 2 is assembled to the pressing block body 1.

[0071] This solution also includes two vibration plates 42 , which are arranged on the side of the machine platform 4 . The diaphragm feeding assembly 9 and the sealing ring feeding assembly 10 are both provided with feeding channels 43 , and the feeding channels 43 correspond to the vibration plates 42 one by one.

[0072] The vibration plate 42 is used to realize automatic feeding of the diaphragm 2 and the sealing ring 3 , and the feeding channel 43 is used to connect the vibration plate 42 and the diaphragm positioning platform 37 , and the vibration plate 42 and the sealing ring positioning platform 11 .
