Description

Technical Field

[0001] The invention belongs to the technical field of vehicle manufacturing equipment, and in particular relates to an air suspension fixing assembly tool. Background Art

[0002] The air suspension system uses an air compressor to form compressed air. By controlling the air compressor and the exhaust valve, the air pressure in the air spring is adjusted to automatically compress or extend the spring, thereby achieving a shock-absorbing effect and adjusting the vehicle body height and suspension hardness. Air suspension fixtures are suitable for installing and fixing devices of the air suspension system.

[0003] In the existing air suspension fixing assembly tooling, for example, the patent with publication number CN206048002U discloses an air suspension fixing assembly tooling, including a base, a positioning module, a moving module and a loading module, wherein the positioning module is symmetrically installed on the left side of the upper end of the base, the moving module is installed in the middle of the upper end of the base, and the loading module is installed on the upper right end of the moving module, which can realize the function of accurately installing the fixing on the square shaft. The positioning module accurately fixes the square shaft in the middle of the moving module, realizes the function of accurately positioning the square shaft, which is conducive to the accurate installation of the fixing, the pushing unit realizes the function of accurately positioning the fixing, and is conducive to the accurate installation of the fixing, and the loading module realizes the function of taking the fixings one by one, thereby improving production efficiency and reducing the labor intensity of workers.

[0004] The prior art still has the following deficiencies:

[0005] 1. In the existing device, when taking materials, the slider moves back and forth along the electric slide rail to transport the air suspension fixture from the loading module to the bottom of the square shaft. This method of transporting the air suspension fixture has low transportation efficiency and directly affects the assembly efficiency of the air suspension fixture.

[0006] 2. When feeding, the existing device drives the extrusion unit to extrude the airbag through the fixed frame, and pushes the gas in the airbag into the lifting unit, so that the lifting unit drives the pushing unit to eject upward. After ejection, the pushing unit drives the fixing part to be close to the square shaft. When the airbag stretches or contracts in the empty slot, there is friction between the outer surface of the airbag and the side wall of the empty slot. The airbag is easily damaged after reciprocating friction. The damage of the airbag will directly affect the normal use of the device. Therefore, it is necessary to check the wear of the airbag frequently, and the maintenance cost is high.

[0007] 3. The existing device cannot adjust the position of the fixing part after taking the material. Since the fixing part is placed on the positioning pad manually, there is an error in the placement, and when the fixing part is transmitted downward from the conveyor belt, the vibration of the conveyor belt will also cause the position of the fixing part to deviate, so that when the fixing part is adsorbed on the translation plate, the position of the fixing part on the translation plate deviates from the expected position, resulting in inaccurate installation position of the fixing part.

[0008] 4. The mobile module, extrusion unit and electromagnet of the existing device are driven by different driving sources respectively, the structure is complex and the manufacturing cost of the equipment is high. In addition, the working state of the mobile module, extrusion unit and electromagnet needs to be controlled by a strict control program, which further increases the manufacturing cost of the equipment.

A rack 132 meshing with the driven column gear 27 is fixed on the side wall of one side of the rectangular groove 13.

[0042] The movable seat 2 is provided with a lifting assembly, which includes a second slide groove 28 opened on the upper surface of the movable seat 2, a bidirectional screw rod 31 is rotatably connected in the second slide groove 28, two symmetrical movable blocks 32 are threadedly connected on the bidirectional screw rod 31, and a connecting rod 33 is rotatably connected on the movable block 32. An annular slide groove is opened on the lower surface of the annular plate 24, and two rotating seats are slidably connected in the annular slide groove. One end of the connecting rod 33 away from the movable block 32 is rotatably connected to the rotating seat. When the bidirectional screw rod 31 rotates, it drives the two movable blocks 32 to move closer or farther from each other, thereby driving the annular plate 24 to descend or ascend under the action of the connecting rod 33. The lifting assembly also includes a driving component, which includes a motor 34 fixed to the right side wall of the movable seat 2. The right end of the movable seat 2 is opened There is a speed change chamber 29, in which a drive shaft 35 is rotatably connected, one end of the drive shaft 35 is connected to the output shaft of the motor 34 through a coupling, an incomplete column gear 36 is fixed on the drive shaft 35, a speed change gear set 37 is provided in the speed change chamber 29, and the incomplete gear 36 drives the bidirectional screw 31 to rotate through the speed change gear set 37, a transmission chamber 20 is opened in the middle of the movable seat 2, one end of the drive shaft 35 away from the motor 34 extends into the transmission chamber 20, an incomplete bevel gear 201 is fixed to one end of the drive shaft 35 located in the transmission chamber 20, and a driven bevel gear 202 meshing with the incomplete bevel gear 201 is fixed on the part of the sleeve 21 located in the transmission chamber 20, and the number of teeth of the incomplete bevel gear 201 is half of the number of teeth of the driven bevel gear 202;

[0043] During specific operation, the loading box 12 places the air suspension fixture on the bearing platform 26, controls the motor 34 to rotate forward, and the rotation of the motor 34 drives the drive shaft 35, the incomplete column gear 36 and the incomplete bevel gear 201 to rotate. At this time, the incomplete column gear 36 and the speed gear set 37 are in a separated state, and the incomplete bevel gear 201 and the driven bevel gear 202 are in a meshing state. The incomplete bevel gear 201 drives the driven bevel gear 202 and the sleeve 21 to rotate, thereby driving the lifting rod 22 and the annular plate 24 to rotate 180°, and the bearing platform 26 drives the air suspension fixture to rotate 180° around the central axis of the lifting rod 22 to achieve rapid transportation. In addition, when the sleeve 21 rotates, it drives the driven column gear 27 to rotate. Under the action of the rack 132, the driven column gear 27 rolls in the direction close to the square axis, further improving the transportation efficiency of the air suspension fixture;

[0044] The annular plate 24 is provided with a fixing assembly, which includes two central shafts 41 fixed on the annular plate 24, and two extrusion rods 42 are rotatably connected to the central shaft 41 through a torsion spring, and the two extrusion rods 42 are crossed in a scissor shape, and adjustment ropes 43 are fixed to the ends of the two extrusion rods 42. The fixing assembly also includes an adjustment groove 240 opened on the upper surface of the annular plate 24, and a plurality of rotating rollers 241 arranged in parallel are provided at the bottom of the adjustment groove 240, and a counterweight block 44 is provided above the rotating roller 241, and an adjustment rod 45 is fixed to the upper surface of the counterweight block 44. The adjustment rope 43 of the extrusion rod 42 is straightened in a natural state, and the adjustment rope 43 squeezes the counterweight block 44 to one end of the adjustment groove 240 close to the center of the annular plate 24 through the adjustment rod 45;

[0045] During operation, the annular plate 24 rotates to drive the counterweight 44 to rotate around the central axis of the annular plate 24, so that the counterweight 44 generates centrifugal force. The centrifugal force along the direction of the adjustment slot 240 drives the counterweight 44 to move toward the direction close to the bearing platform 26, so that the adjustment rod 45 squeezes the adjustment rope 43, thereby driving the squeezing rod 42 to rotate and squeeze the air suspension fixing to the center of the bearing platform 26 and fix it. When the air suspension fixing moves to the bottom of the square shaft, the incomplete bevel gear 201 is separated from the driven bevel gear 202, and the incomplete column gear 3 6 meshes with the speed gear set 37, the driven bevel gear 202 and the annular plate 24 stop rotating, the counterweight block 44 loses the centrifugal force, and the extrusion rod 42 returns to the initial position under the action of the torsion spring to release the fixation of the air suspension fixing part. The incomplete column gear 36 drives the two-way screw 31 to rotate at a high speed through the speed gear set 37, thereby driving the two movable blocks 32 away from each other under the action of the threaded fit, thereby pushing the annular plate 24 upward, and the annular plate 24 drives the bearing platform 26 to move upward to press the air suspension fixing part against the square shaft for easy installation.

[0046] The working principle of the present invention is as follows:

[0047] When working, the square shaft is pushed into the arc groove on the support plate 11 and is restricted and fixed by the limit assembly, and the loading box 12 is opened to place the air suspension fixture on the bearing platform 26;

[0048] The motor 34 is controlled to rotate forward, and the motor 34 rotates to drive the drive shaft 35, the incomplete column gear 36 and the incomplete bevel gear 201 to rotate. At this time, the incomplete column gear 36 and the speed gear set 37 are in a separated state, and the incomplete bevel gear 201 and the driven bevel gear 202 are in a meshing state. The incomplete bevel gear 201 drives the driven bevel gear 202 and the sleeve 21 to rotate, thereby driving the lifting rod 22 and the annular plate 24 to rotate 180°, and the bearing platform 26 drives the air suspension fixture to rotate 180° around the central axis of the lifting rod 22 to achieve rapid transportation. In addition, when the sleeve 21 rotates, it drives the driven column gear 27 to rotate. Under the action of the rack 132, the driven column gear 27 rolls in the direction close to the square axis. Compared with the prior art, when the present invention transports the air suspension fixture, the air suspension fixture moves horizontally in the direction close to the square axis and rotates in the direction close to the square axis with the central axis of the annular plate 24 as the center, which greatly improves the transportation efficiency of the air suspension fixture, thereby improving the assembly efficiency of the air suspension fixture;

[0049] The rotation of the annular plate 24 drives the counterweight 44 to rotate around the central axis of the annular plate 24, so that the counterweight 44 generates a centrifugal force F1. The component force F2 of the centrifugal force F1 along the length direction of the adjusting groove 240 drives the counterweight 44 to move in the direction close to the bearing platform 26. The rotating roller 241 at the bottom of the adjusting groove 240 can convert the sliding friction between the counterweight 44 and the bottom of the adjusting groove 240 into rolling friction, thereby reducing the resistance encountered by the counterweight 44 when moving. The movement of the counterweight 44 causes the adjusting rod 45 to squeeze the adjusting rope 43, thereby driving the squeezing rod 42 to rotate and squeeze the air suspension fixing to the center of the bearing platform 26 and fix it. When the air suspension fixing moves to the bottom of the square shaft, the incomplete The bevel gear 201 is separated from the driven bevel gear 202, the incomplete column gear 36 is meshed with the speed gear set 37, the driven bevel gear 202 and the annular plate 24 stop rotating, the counterweight 44 loses the centrifugal force F1, and the extrusion rod 42 recovers to the initial position under the action of the torsion spring to release the fixation of the air suspension fixing. Compared with the prior art, the present invention ingeniously uses the centrifugal force to make the extrusion rod 42 adjust and fix the position of the air suspension fixing when conveying the air suspension fixing, so that the installation position of the air suspension fixing is more accurate, and after the air suspension fixing moves to the bottom of the square shaft, the extrusion rod 42 automatically releases the fixation of the air suspension fixing, without manual operation;

[0050] After the incomplete column gear 36 is meshed with the speed gear set 37, the incomplete column gear 36 drives the bidirectional screw 31 to rotate at a high speed through the speed gear set 37, thereby driving the two movable blocks 32 to move away from each other under the action of the threaded fit, thereby pushing the annular plate 24 upward, and the annular plate 24 drives the bearing platform 26 to move up to press the air suspension fixing part against the square shaft for easy installation. Compared with the prior art, the present invention abandons the method of using an air bag to push the air suspension fixing part up, and adopts a mechanical structure to push the air suspension fixing part up, thereby avoiding the situation where the air bag wear affects the use of the device, and the device operation is more stable. At the same time, it can also reduce the maintenance times of the device and reduce the maintenance cost.

[0051] After the air suspension fixture is installed, the motor 34 is controlled to reverse and drive the bidirectional screw 31 to rotate at high speed, so that the two movable blocks 32 are close to each other to move the annular plate 24 downward, and when the incomplete column gear 36 is separated from the speed gear set 37, the incomplete bevel gear 201 and the driven bevel gear 202 are engaged, driving the support platform 26 to move in the direction close to the loading box 12 and rotate in the direction close to the loading box 12;

[0052] The conveying assembly, lifting assembly and fixing assembly of the present invention are driven by only a single motor 34, and the structure is simple and the manufacturing cost of the equipment is low. In addition, the components have clear division of labor and cooperate with each other, which is conducive to improving work efficiency. In addition, compared with the prior art, the present invention saves the cost of high-precision control programs, further reducing the manufacturing cost of the equipment.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
