[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1 As shown in the figure, this application discloses an automotive subframe bushing pressing device, comprising: a frame 1; a mobile platform 2 movably mounted on the frame 1; a lifting platform 3 for mounting the subframe 10 and movably mounted on the mobile platform 2; an industrial robot 4 for gripping and placing the bushing; a pair of first mounting platforms 51, perpendicular to the moving direction of the mobile platform 2, respectively disposed on both sides of the mobile platform 2; a first telescopic component 61 and a second telescopic component 62, coaxially disposed on the first mounting platform 51, respectively located on the upper and lower sides of the subframe 10; wherein, the first telescopic component 61 and / or the piston rod of the second telescopic component 62 is used to receive the bushing; at least two pairs of second mounting platforms 52 are located on both sides of the first platform along the moving path of the moving platform 2; perpendicular to the moving direction of the moving platform 2, each pair of second mounting platforms 52 is located on both sides of the moving platform 2; the first support component 71 and the second support component 72 are both disposed on the second mounting platform 52, located on the upper and lower sides of the subframe 10 respectively, for supporting the subframe 10; the first linear drive module is used to drive the moving platform 2 to move; the second linear drive module is used to drive the lifting platform 3 to rise and fall.

[0023] Combination Figure 2 and Figure 3 As shown, in specific use, the subframe 10 to be pressed with the bushing is placed on the lifting platform 3, and the industrial robot 4 grabs the bushing and places it on the piston rod of the first telescopic component 61 and / or the second telescopic component 62; then the first linear drive module is started to transport the subframe 10 toward the first mounting platform 51. When the position of the subframe 10 where the bushing needs to be pressed is between the first telescopic component 61 and the second telescopic component 62, the first linear drive module stops.

[0024] When the bushing needs to be pressed down, the lower side of the subframe 10 is supported by the second support member 72, and the piston rod of the first telescopic member 61 receives the bushing. By making one telescopic stroke, the bushing on the piston rod of the first telescopic member 61 can be pressed down and installed into the subframe 10.

[0025] When the bushing needs to be pressed upward, the second linear drive module is activated, driving the lifting platform 3 to rise until the upper side of the subframe 10 abuts against the first support component 71. The upper side of the subframe 10 is supported by the first support component 71, and the piston rod of the second telescopic component 62 receives the bushing. By making one telescopic stroke, the bushing on the piston rod of the second telescopic component 62 can be pressed into the subframe 10.

[0026] When the bushings need to be pressed in from the top and bottom, the piston rods of the first telescopic component 61 and the second telescopic component 62 both receive the bushings. Referring to the working process of pressing the bushings downward and pressing the spring bushings upward as described above, the piston rods of the first telescopic component 61 and the second telescopic component 62 are activated alternately. The piston rods of the first telescopic component 61 and the second telescopic component 62 each make one extension stroke, so that the bushings on the piston rods of the first telescopic component 61 and the second telescopic component 62 can be pressed into the subframe 10 synchronously.

[0027] In this utility model, by setting a moving component, the subframe 10 can be automatically fed along the length direction, and different mounting hole positions can be placed between the first telescopic component 61 and the second telescopic component 62, so that the pressing work of the bushing on the subframe 10 can be completed step by step automatically.

[0028] In this utility model, by setting up an industrial robot 4, the bushing loading operation can be completed automatically, reducing the amount of manual loading work and effectively improving the bushing pressing efficiency on the subframe 10.

[0029] In this utility model, by setting a first support component 71 and a second support component 72, during the feeding of the subframe 10, the second support component 72 is located on the lower side of the subframe 10, which can support the subframe 10 and ensure stable feeding of the subframe 10; during the bushing pressing operation of the subframe 10, the second support component 72 can provide auxiliary support to the lower side of the subframe 10; during the bushing pressing operation of the subframe 10, the first support component 71 can provide auxiliary support to the upper side of the subframe 10.

[0030] It is worth mentioning that the industrial robot 4 can be a six-axis robot that is already available on the market; it is also worth mentioning that the loading and unloading work of the subframe 10 onto the lifting platform 3 can also be completed by another six-axis robot, further improving the automation level of this pressing equipment.

[0031] Preferably, the device further includes a positioning pin 6, which is disposed at the end of the piston rod of the first telescopic component 61 and the second telescopic component 62, for receiving the bushing; by setting the positioning pin 6, the inner hole of the bushing gripped by the industrial robot 4 passes through the positioning pin 6, thereby completing the feeding of the bushing on the first telescopic component 61 and / or the second telescopic component 62.

[0032] Reference Figure 4 As shown, the device also includes: a first load-bearing component 81 and a second load-bearing component 82, movably mounted on the first mounting platform 51, located on the upper and lower sides of the subframe 10 respectively; a third support component 73 and a fourth support component 74, respectively mounted on the first load-bearing component 81 and the second load-bearing component 82; a third linear drive module for driving the first load-bearing component 81 to move, enabling the third support component 73 to be positioned between the subframe 10 and the first telescopic component 61; and a fourth linear drive module for driving the second load-bearing component 82 to move, enabling the fourth support component 74 to be positioned between the subframe 10 and the second telescopic component 62.

[0033] In specific operation, when the bushing is pressed down by the subframe 10, the piston rod of the second telescopic component 62 needs to be in a retracted state, the second bearing component 82 needs to cover the second telescopic component 62, and the fourth support component 74 needs to be located between the subframe 10 and the second telescopic component 62. The fourth support component 74 supports the lower side of the subframe 10 so that the first telescopic component 61 can press the bushing down into the subframe 10.

[0034] When the bushing needs to be pressed on the subframe 10, the piston rod of the first telescopic component 61 is in a retracted state, the first bearing component 81 covers the first telescopic component 61, and the third support component 73 is located between the subframe 10 and the first telescopic component 61; the third support component 73 supports the upper side of the subframe 10, so that the second telescopic component 62 can press the bushing upward into the subframe 10.

[0035] By setting the first bearing component 81 and the second bearing component 82, the third support component 73 and the fourth support component 74 can alternately support the upper and lower sides of the subframe 10, thereby ensuring the stability of the upper and lower press-fit bushings of the subframe 10.

[0036] Reference Figure 4As shown, the third linear drive module is a linear gear transmission module, including: a slider 84 disposed on the first supporting component 81, and a slide rail 83 disposed on the first mounting platform 51, with the slider 84 slidably disposed on the slide rail 83; a servo motor 85 mounted on the first supporting component 81, and a rack disposed on the first mounting platform 51; a gear disposed on the output shaft of the servo motor 85, with the gear and rack meshing together; rotation of the output shaft of the servo motor 85 drives the first supporting component 81 to slide along the slide rail 83. Similarly, the installation of the fourth linear drive module can be obtained, which will not be described in detail here.

[0037] Preferably, both the first mounting platform 51 and the second mounting platform 52 are C-shaped, and the subframe 10 can pass through the C-shaped first mounting platform 51 and the second mounting platform 52 during the feeding process.

[0038] Reference Figure 5 and Figure 6 As shown, the first linear drive mold base includes: a belt 91; two tensioning wheels 92, which are rotatably mounted on the frame 1 and drive the belt 91 to drive one of the tensioning wheels 92 to rotate; and a clamping plate 94, which clamps the belt 91 at one end and is fixedly mounted on the moving platform 2 at the other end.

[0039] In this embodiment, the tension wheel 92 is rotated by the drive motor 93, which in turn drives the belt 91 to move, thereby driving the clamping plate 94 to move the moving platform 2, so that the sub-frame 10 moves along the feeding direction.

[0040] Specifically, the device also includes: several positioning plates 31, which are set on the lifting platform 3 for positioning the subframe 10; a connecting rod 32, which is hinged to the lifting platform 3; a pressure rod 33, which is hinged to the connecting rod 32, and one end of the pressure rod 33 is used to press against the subframe 10; and a third telescopic component 63, the main body of which is set on the lifting platform 3, and the piston rod of the third telescopic component 63 is connected to the end of the pressure rod 33 away from the subframe 10.

[0041] In actual operation, the subframe 10 is positioned and fixed on the lifting platform 3 by the positioning insert plate 31. Then, the third telescopic component 63 is activated. The piston rod of the third telescopic component 63 extends, which drives one end of the pressure rod 33 to press down the subframe 10 and fix the subframe 10 on the lifting platform 3 for subsequent bushing pressing work.

[0042] It is worth mentioning that the second linear drive module includes: a fourth telescopic component 64 mounted on the mobile platform 2. The piston rod of the fourth telescopic component 64 is connected to the lifting platform 3. The lifting platform 3 can be driven to move up and down in the vertical direction by the telescopic movement of the piston rod of the fourth telescopic component 64.

[0043] Of course, in order to improve the stability of the lifting platform 3 during lifting movements, a guide rod parallel to the fourth telescopic component 64 can be installed on the lifting platform 3. The guide rod can be slidably set inside the moving platform 2.

[0044] It is understandable that the first telescopic component 61 and the second telescopic component 62 can be electric push rods, which are powered by a rotary motor. Pressure-displacement sensors can also be installed on the electric push rods to monitor the entire pressing process, monitor the pressure and position of the bushing in real time, and ensure that all parameters are within the pre-set range to complete the pressing action.

[0045] It is worth mentioning that the third telescopic component 63 and the fourth telescopic component 64 can be made of pneumatic cylinders, hydraulic cylinders, or electric push rods.
