Description

Technical Field

[0001] The invention belongs to the technical field of automobile column assembly, and in particular relates to a long bolt press-fitting device for an automobile electric column. Background Art

[0002] As a key component connecting the steering wheel and steering gear of a car, the electric column plays a vital role in the car. It is not only responsible for regulating the direction of the vehicle, but also undertakes the tasks of transmitting torque and absorbing the energy generated during collision.

[0003] The automobile electric column includes an upper bracket, a lower bracket, an upper protective tube, a lower protective tube and a connecting plate. One end of the upper protective tube is connected to the lower protective tube, and the other end of the lower protective tube is connected to the lower bracket. A connecting plate is provided at each end of the upper bracket, and the connecting plate is rotatably connected to one end of the upper bracket. When the automobile electric column is assembled, the upper bracket connected with the connecting plate is installed together with the lower protective tube by a long bolt, that is, the long bolt needs to be passed through the mounting hole of the connecting plate at one end of the upper bracket and then pressed into the mounting hole on the lower protective tube and passed out from the mounting hole of the connecting plate at the other end of the upper bracket. In the prior art, during the assembly process of the automobile electric column, the long bolt cannot be inserted into the mounting hole of the connecting plate because the upper bracket blocks a part of the mounting hole of the connecting plate when it is delivered, thereby making it impossible to press-fit the long bolt.

By using the clamping driver to drive the first extension plate to extend so as to gradually approach the upper bracket, the upper bracket can gradually enter the gap between the top surface of the second plate body and the bottom surface of the first extension plate, so that the upper bracket is stuck in this gap to fix the upper bracket, and prevent the upper bracket from loosening or falling during the long bolt press-fitting process.

[0010] According to some preferred embodiments of the present invention, at least one first fixed block is fixedly provided on the bottom surface of the support frame, at least one second fixed block is fixedly provided on the top surface of the bottom plate, the first fixed block and the second fixed block are provided in one-to-one correspondence, a fixed rod is fixedly provided on the first fixed block, the fixed rod penetrates the thickness direction of the second fixed block and is slidably connected with the second fixed block, a first elastic member is sleeved on the outer wall of the fixed rod, one end of the first elastic member contacts the side of the first fixed block close to the second fixed block, and the other end of the first elastic member contacts the side of the second fixed block close to the first fixed block. The provision of the first elastic member can ensure that the thrust generated on the electric column of the automobile when the electronic press pushes the long bolt to be pressed in is borne by the first load-bearing component and the second load-bearing component, and will not be completely borne on the bottom plate of the positioning mechanism, thereby avoiding excessive load on the bottom plate.

[0011] According to some preferred implementation aspects of the present invention, the first angle adjustment drive assembly includes a first mounting plate and two first angle adjustment drivers relatively arranged on the top surface of the first mounting plate; each of the insertion components also includes a base, a third fixed block, a fourth fixed block and a second elastic member, the bottom surface of the base is connected to the top surface of the first angle adjustment driver, the third fixed block is fixedly arranged on one side of the insertion block, the end of the base away from the upper bracket is fixedly arranged with the fourth fixed block, the insertion block is slidably connected to one side of the base, one end of the second elastic member is connected to the third fixed block, and the other end of the second elastic member is connected to the fourth fixed block. The boss at one end of the insertion block is inserted into the mounting hole of the corresponding connecting plate. When the second angle adjustment drive assembly drives the insertion assembly to rise as a whole, since the boss is inserted into the mounting hole of the connecting plate, the insertion block will drive the connecting plate to rotate upward and forward (close to the direction of the lower bracket) until it reaches a position that satisfies the long bolt press-fitting, and the mounting hole of the connecting plate is not blocked by the upper bracket.

[0012] According to some preferred embodiments of the present invention, the connecting plate angle adjustment mechanism also includes a third angle adjustment drive assembly, the top surface of the third angle adjustment drive assembly is fixedly connected to the bottom surface of the first mounting plate, the bottom surface of the third angle adjustment drive assembly is connected to the second angle adjustment drive assembly, and the third angle adjustment drive assembly is used to drive the two insertion assemblies to move simultaneously in a direction closer to and / or away from the upper bracket.

[0013] According to some preferred embodiments of the present invention, the pressing mechanism includes a support seat, a pressure head fixing seat, an electronic press, a first pressing drive assembly, a second pressing drive assembly and a long bolt positioning assembly; the pressure head fixing seat is slidably connected to the top surface of the support seat; the pressure head is fixedly arranged at one end of the pressure head fixing seat away from the electronic press; the electronic press is used to push the pressure head fixing seat to move toward the positioning mechanism; the pressure head fixing seat is also slidably connected to the second pressing drive assembly; the second pressing drive assembly is connected to the long bolt positioning assembly; the first pressing drive assembly is used to drive the long bolt positioning assembly to move toward and / or away from the positioning mechanism; the second pressing drive assembly is used to drive the long bolt positioning assembly to rise and fall in the vertical direction. Long bolts need to be positioned using a long bolt positioning assembly before press-fitting. However, as the pressure head pushes the long bolt forward and continues to extend, the long bolt positioning assembly of the present invention will occupy the press-fitting path and block the pressure head from continuing to extend. At this time, it is necessary to cooperate with the first press-fitting drive assembly and the second press-fitting drive assembly to drive the long bolt positioning assembly to move upward and move away from the electric column of the automobile to make way for the press-fitting path and ensure that the pressure head can continue to push the long bolt for press-fitting under the action of the electronic press. In addition, when the long bolt positioning assembly needs to make way for the pressure head, most of the long bolt has been press-fitted into the mounting hole of the connecting plate and the mounting hole of the lower protective tube. At this time, it is no longer necessary to use the long bolt positioning assembly to place and position the long bolt, so it can be driven to make way by the first press-fitting drive assembly and the second press-fitting drive assembly.

[0014] According to some preferred implementation aspects of the present invention, the long bolt positioning assembly includes two symmetrically arranged clamping jaws and a clamping jaw driver connected to the two clamping jaws, the clamping jaw driver is used to drive the two clamping jaws to move closer to and / or farther from each other, the clamping jaw includes a connecting claw portion and an extending claw portion, one end of the connecting claw portion is connected to the clamping jaw driver, and the other end of the connecting claw portion is connected to the extending claw portion; a side of one extending claw portion close to the other extending claw portion is set as an inclined surface, the inclined surface is inclined downward from the top surface of the extending claw portion to the side close to the other extending claw portion, the two inclined surfaces of the two extending claw portions are used together to form a receiving groove for placing the long bolt, and the length of the extending claw portion is less than the length of the long bolt. In some embodiments of the present invention, the two inclined surfaces of the two extending claw portions cooperate with each other to form a receiving groove for stably placing the long bolt. When preparing to place the long bolt on the two jaws and start press-fitting, it is necessary to drive the two jaws closer to each other under the action of the jaw driver until the distance between the bottom edges of the two inclined surfaces of the two extending claws is smaller than the outer diameter of the long bolt; and use the first press-fitting drive assembly and the second press-fitting drive assembly to adjust the position of the long bolt positioning assembly to ensure that when the long bolt is placed on the two jaws, the axis line of the pressure head, the axis line of the long bolt, the centers of the mounting holes of the two connecting plates and the center of the mounting hole of the lower protective tube are all located on the same horizontal line parallel to the length direction of the long bolt.

[0015] According to some preferred embodiments of the present invention, the load-bearing mechanism includes a load-bearing seat, a load-bearing frame, a first load-bearing component and a second load-bearing component, the bottom surface of the load-bearing frame is fixedly connected to the top surface of the load-bearing seat, and the first load-bearing component and the second load-bearing component are both arranged on the load-bearing frame; the first load-bearing component includes a load-bearing rod, a push rod, a connecting rod and a load-bearing rod driver, one end of the load-bearing rod is fixedly connected to one end of the push rod, the other end of the push rod is fixedly connected to the connecting rod, the other end of the connecting rod is connected to the load-bearing rod driver, the push rod is slidably connected to the load-bearing seat, and the load-bearing rod driver is used to drive the load-bearing rod to move back and forth along its length direction.

[0017] According to some preferred embodiments of the present invention, the push rod includes a connecting block fixedly connected to one end of the load-bearing rod and a rod body fixedly connected to one end of the connecting block away from the load-bearing rod, the bottom surface of the connecting block is flush with the bottom surface of the rod body, and the top surface of the connecting block is higher than the top surface of the rod body, when the connecting plate is in the second state, the load-bearing plate is located above the rod body, the end of the load-bearing rod away from the push rod is close to the automobile electric column, and a side surface of the connecting block close to the rod body and a side surface of the load-bearing plate close to the connecting block are located on the same vertical plane.

In addition, the automotive electric column placed on the positioning mechanism and the fixing assembly are in a quick-change form, and workpieces of different models can be replaced to increase the compatibility of the equipment.

The first elastic member 17 of this embodiment is preferably a spring, and when the first connecting plate 102 and the second connecting plate 103 are both in the first state, the first elastic member 17 is in a natural state. The provision of the first elastic member 17 enables the support frame 12 and the fixing assembly 13, as well as the automotive electric column 100 placed on the fixing assembly 13, to float when subjected to the thrust of the press-fitting mechanism 3.

[0044] Specifically, the fixing assembly 13 includes a fixing plate 131, a first fixing seat 132 fixedly arranged on the top surface of the fixing plate 131, a second fixing seat 133, a third fixing seat 134 and a clamping driver 135.

The clamping driver 135 is used to drive the first extension plate 136 to move toward or away from the upper bracket 101. When the clamping driver 135 drives the first extension plate 136 to extend to gradually approach the upper bracket 101, the upper bracket 101 can gradually enter the gap between the top surface of the second plate body 138 and the bottom surface of the first extension plate 136, thereby clamping the upper bracket 101 in this gap to fix the upper bracket 101 and prevent the upper bracket 101 from loosening or falling during the press-fitting process of the long bolt 107.

[0058] In this embodiment, when the first connecting plate 102 and the second connecting plate 103 are both in the second state and the long bolts 107 have not yet been pressed, the end of the load-bearing rod 431 away from the push rod is close to the automobile electric column 100 and has a small distance. When the electronic press 34 pushes the pressure head 32 to press the long bolts 107, the side of the automobile electric column 100 close to the load-bearing mechanism 4 contacts and presses against the load-bearing rod 431.

[0059] The second load-bearing component 44 includes a load-bearing plate 441 and a load-bearing plate driver 442.

[0060] In order to ensure the load-bearing effect of the second load-bearing component 44, when the first connecting plate 102 and the second connecting plate 103 are in the second state, the load-bearing plate 441 is located above the rod body 4322, and the end of the load-bearing rod 431 away from the push rod is close to the automobile electric column 100, and the side of the connecting block 4321 close to the rod body 4322 and the side of the load-bearing plate 441 close to the connecting block 4321 are located on the same vertical plane, and then, under the action of the load-bearing plate driver 442, the load-bearing plate 441 can be driven to move downward to gradually approach the top surface of the rod body 4322 until the bottom surface of the load-bearing plate 441 is in contact with the top surface of the rod body 4322 and the side of the load-bearing plate 441 close to the connecting block 4321 is in contact with the side of the connecting block 4321 close to the rod body 4322.

[0061] The following briefly describes the working process of the long bolt press-fitting device for the automotive electric column 100 in this embodiment for press-fitting the long bolt 107:

[0062] Take an automobile electric column 100 and place it on the fixing assembly 13 of the positioning mechanism 1, start the clamping jaw driver 392 to adjust the distance between the two clamping jaws and place a long bolt 107 on the two clamping jaws; the clamping driver 135 is actuated to drive the first extension plate 136 and the second extension plate to gradually approach the upper bracket 101 and fix the upper bracket 101; the pressing driver 141 is actuated to drive the pressing block 143 to press the automobile electric column 100 downward. The first angle adjustment driver 222 and the third angle adjustment driver 242 are actuated to drive the two plug blocks 211 to move and adjust their positions, so that the first boss 2121 and the second boss 2122 are respectively inserted into the first mounting hole 1021 of the first connecting plate 102 and the second mounting hole 1031 of the second connecting plate 103. The second angle adjustment driver 232 is actuated to drive the two plug blocks 211 to rotate, thereby driving the first connecting plate 102 and the second connecting plate 103 to rotate to the corresponding angles to the required position for the long bolt 107 to be pressed. Subsequently, the first angle adjustment driver 222 , the third angle adjustment driver 242 , and the second angle adjustment driver 232 are retracted to their original positions in sequence.

[0063] The bearing rod driver 434 moves to drive the bearing rod 431 to extend to the side close to the automobile electric column 100 but not in contact, and the bearing plate driver 442 moves to drive the bearing plate 441 to move downward until the bottom surface of the bearing plate 441 fits with the top surface of the rod body 4322, and the side surface of the bearing plate 441 close to the connecting block 4321 fits with the side surface of the connecting block 4321 close to the rod body 4322.

[0064] As the pressing head 32 pushes the long bolt 107 to continue to extend forward, when the pressing head 32 is extended to the point of about touching the clamping jaws, the clamping jaw driver 392 is actuated to drive the two clamping jaws away from each other, so that the two clamping jaws are separated from the long bolt 107; the second pressing driver 361 is actuated to drive the long bolt positioning assembly 39 to move upward, and the first pressing driver 351 is actuated to drive the long bolt positioning assembly 39 to move backward (away from the upper bracket 101), so that the long bolt positioning assembly 39 gives way to the pressing path of the pressing head 32.

[0065] The electronic press 34 continues to push the pressure head 32 to press the long bolt 107 into place, so that the end of the long bolt 107 away from the pressure head 32 extends from the second mounting hole 1031 of the second connecting plate 103. Subsequently, the electronic press 34 returns to its original position, the bearing plate driver 442 drives the bearing plate 441 to move upward to its original position, the bearing rod driver 434 drives the bearing rod 431 back to its original position, the first press driver 351 acts, and the second press driver 361 acts to drive the long bolt positioning assembly 39 back to its original position; the clamping driver 135 acts to drive the first extension plate 136 and the second extension plate to retract, and the upper bracket 101 is released; the clamping driver 141 acts to drive the clamping block 143 to move upward, and the electric column 100 of the automobile is released, and the electric column 100 of the automobile with the long bolt 107 installed is manually unloaded.
