Description

Technical Field

[0001] This disclosure belongs to the field of automotive assembly technology, and particularly relates to a modular automotive assembly equipment. Background Technology

[0002] Currently, when assembling the front sliding pillar module for automobiles, an integrated assembly platform is used. The front sliding pillar and front brake can be accurately positioned. From sample delivery, assembly, tightening, and unloading, everything is done in the same station. This is not conducive to the rapid assembly and handling of the module. When assembling the brake and sliding pillar piston rod for different car models, different assembly platforms are required to meet the needs of different car models, which requires a large investment. Summary of the Invention

[0003] The purpose of this disclosure is to provide a modular automotive assembly equipment to solve the above-mentioned problems, addressing efficiency issues and the problem of multiple product platforms co-producing during the assembly of modular automotive front sliding pillar modules. It separates the positioning and clamping mechanism from the module moving support mechanism on the assembly line. Each module moving support mechanism meets the assembly requirements of its corresponding workstation, completing the initial assembly. At the positioning and tightening workstation, the positioning and clamping mechanism moves to the position of the module moving support mechanism and automatically presses the front brake. The piston rod end positioning mechanism locks the piston rod position. After the clamping mechanism restricts the rotation of the sliding pillar, the fastening nut is tightened to the target parameters. After tightening, the positioning and clamping mechanism releases the module. After the module falls into the support mechanism, the positioning and clamping mechanism returns to its original position along the guide rail.

[0004] This positioning and clamping mechanism is placed on a slide rail and is designed for reciprocating movement. It is automatically controlled and allows for the setting of corresponding fastener limit positions, slide clamping mechanism height, piston rod end height and angle, and different slide lengths based on different vehicle models. During use, the positioning and clamping mechanism is positioned according to the information input from the module, with the telescopic slide rail of the positioning and clamping mechanism perpendicular to the track line of the support mechanism. If only one vehicle model is used, the adjustment part is fixed.

[0005] The support mechanism can be towed by the BEV vehicle or driven by an industrial chain. It supports the position of the brake bearing and has sufficient strength and stability. The connection between the slide column and the brake steering knuckle is fastened with threads. The slide column is supported on the bracket by a spring. The support mechanism carries the module components along a fixed track.

[0006] The positioning and clamping mechanism and the module moving support mechanism are fitted at the brake contact surface and the brake bearing axis is aligned. Positioning is primarily based on the flange surface, with the end of the sliding piston rod serving as auxiliary positioning. Through mechanism clamping, the angle between the brake rim mounting surface and the sliding piston axis is controlled within a specific range, preventing relative movement during tightening. This achieves the goal of improving clamping efficiency and positioning accuracy.

[0007] This disclosure separates the equipment for positioning, clamping, and tightening processes from the assembly line support equipment through tooling fixture design and automatic control strategy. The positioning, clamping, and tightening equipment, through an automatic adjustment device, realizes different positions of different brakes and sliding piston rod ends, thus achieving product assembly devices with different positioning angles.

[0008] This disclosure achieves the above objectives through the following technical solutions:

[0009] A modular automotive assembly equipment includes a module moving support mechanism, a positioning and clamping mechanism, and a tightening auxiliary mechanism; the module moving support mechanism is used to carry and drive a brake assembly and a slide column assembly to move, and the brake assembly and the slide column assembly are pre-tightened by fasteners;

[0010] The positioning and clamping mechanism is vertically slidably installed at the work station, and the tightening auxiliary mechanism is set on the positioning and clamping mechanism. When the module moving support mechanism drives the brake assembly and the slide column assembly to the work station of the positioning and clamping mechanism, the positioning and clamping mechanism slides to the position of the module moving support mechanism to position and clamp the brake assembly and the slide column assembly. The tightening auxiliary mechanism then tightens the fastener to the set target after restricting the fastener.

[0011] As a further optimization of this disclosure, the module moving support mechanism includes a steering wheel bracket, rollers, support frame, brake bracket, sliding column support frame, and support wheel frame;

[0012] The rollers are mounted on the steering wheel bracket and the support wheel frame, the steering wheel bracket pin is mounted on the support frame, and the brake bracket and the sliding column support frame are arranged on the support frame.

[0013] As a further optimization of this disclosure, the positioning and clamping mechanism includes a positioning mechanism, a brake pressing mechanism, a slide column clamping mechanism, and an auxiliary positioning mechanism; the brake pressing mechanism is slidably mounted on the track groove of the positioning mechanism, and the auxiliary positioning mechanism is slidably mounted on the positioning mechanism; the slide column clamping mechanism is disposed on the positioning mechanism and is used to fix the slide column assembly.

The positioning sleeve is driven by the sliding column limiting drive cylinder along the axis of the sliding column limiting sleeve; the sliding column limiting drive cylinder is mounted on the sliding column limiting moving seat and is driven by the sliding column limiting rotation drive device; the height adjustment device is mounted on the sliding column limiting mounting seat and the lead screw on the adjustment device drives the sliding column limiting moving seat to move up and down; the sliding column limiting mounting seat and the positioning mechanism seat can move relative to each other along the auxiliary limiting outer slide rail and the auxiliary limiting inner slide rail; the auxiliary limiting outer slide rail is mounted on the sliding column limiting mounting seat and the auxiliary limiting inner slide rail is mounted on the positioning mechanism seat.

[0015] As a further optimization of this disclosure, the sliding column clamping mechanism is used to clamp the sliding column assembly, including a clamping mechanism sliding drive device, a sliding column clamping base, a base positioning pin, a clamping upper seat, a clamping mechanism support, a clamping mechanism slider, a clamping upper seat drive device, and an upper seat drive rod;

[0016] The clamping mechanism sliding drive device is installed on the positioning mechanism seat. The base positioning pin, the clamping mechanism slider and the positioning mechanism seat cooperate. According to the corresponding position parameters of the slide column assembly when the brake assembly cooperates with the slide column assembly, the clamping mechanism sliding drive device drives the clamping mechanism support to the corresponding position. The slide column clamping mechanism can move up and down relative to the positioning mechanism seat.

[0017] The slide column assembly is placed on the slide column clamping base, and the clamping upper seat driving device drives the upper seat driving rod to move upward, so that the clamping upper seat presses the slide column assembly.

[0018] As a further optimization of this disclosure, the tightening auxiliary mechanism includes a fastener limiter, a limiter working cylinder, a limiter movement controller, a drive wheel, a vertical slide rail for the limiter working cylinder, a horizontal slide rail for the limiter working cylinder, and a limiter drive device.

[0019] The fastener limiter is driven by the limiter working cylinder and cooperates with the fastener to prevent the fastener from rotating during the tightening process;

[0020] The transverse slide rail of the limiter working cylinder is installed on the limiter working cylinder and cooperates with the vertical slide rail of the limiter working cylinder to achieve transverse movement. The vertical slide rail of the limiter working cylinder cooperates with the long hole rail in the positioning mechanism seat to realize the sliding of the vertical slide rail of the limiter working cylinder in the long hole. The vertical slide rail of the limiter working cylinder is restricted by the end stop block to prevent it from falling off the positioning mechanism seat.

[0021] The limiter movement controller controls the drive wheel to move toward the brake assembly side and engage with the transverse slide rail of the limiter working cylinder, or the limiter movement controller controls the drive wheel to move toward the other side of the brake assembly and engage with the vertical slide rail of the limiter working cylinder.

[0022] The beneficial effects of this disclosure are as follows:

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] like Figure 1 As shown, a modular automotive assembly equipment includes a module moving support mechanism 1, a positioning and clamping mechanism 2, and a tightening auxiliary mechanism 4. The module moving support mechanism 1 is used to support and drive the brake assembly 3 and the slide column assembly 6 to move. The brake assembly 3 and the slide column assembly 6 are pre-tightened by fasteners 5.

[0033] Before the assembly parts are positioned, clamped, and tightened, the brake assembly 3 and the slide column assembly 6 are placed on the module moving support mechanism 1, and the fasteners 5 pre-tighten the two parts. The module moving support mechanism 1 can be driven along the track by the BEV trolley or other power sources.

[0034] When the module moving support mechanism 1, carrying the brake assembly 3, the slide column assembly 6, and the fastener 5, moves to the position of the positioning and clamping mechanism 2, the positioning, clamping, and tightening auxiliary mechanism 4 on the positioning and clamping mechanism 2 is in its initial state. It slides along the track perpendicular to the module moving support mechanism 1 to the position of the module moving support mechanism 1. At this time, the brake support hole of the positioning and clamping mechanism 2 is coaxial with the bearing of the brake assembly 3. The base of the positioning and clamping mechanism 2 is lower than the mounting surface of the brake assembly 3. After being coaxial with the bearing of the brake assembly 3, it moves upward to fit against the mounting surface of the brake assembly 3. The positioning and clamping mechanism 2 positions the end of the slide column assembly 6, so that the piston axis of the slide column assembly 6 forms a fixed angle with the rim mounting surface of the brake assembly 3.

[0035] Press the outer cylinder of the sliding column, tighten the auxiliary mechanism 4 and the limiting fastener 5, and then tighten to the set target.

[0036] The clamping, positioning, and tightening mechanism 2 returns to its initial state and moves back to its original position along the sliding track.

[0037] The module moving support mechanism 1 carries the brake assembly 3 and the slide column assembly 6 together and moves to the next work station.

[0038] Based on the external shape and dimensions of the separately assembled slide column assembly 6 and brake assembly 3 series, the appropriate opening width and contact area of ​​the positioning and clamping mechanism 2 platform are designed to meet the requirements of different platform components. The positioning and clamping mechanism 2 provides an installation adjustment mechanism and a clamping mechanism mounting support. This platform is a rigid structure. After the slide column assembly 6 and brake assembly 3 are assembled, the sleeve of the auxiliary positioning device of the slide column assembly 6 cooperates with the piston rod at the end of the slide column assembly 6 and is assembled together with the adjustment mechanism in the positioning and clamping mechanism 2. The positioning adjustment mechanism can move vertically up and down relative to the positioning and clamping mechanism 2 platform, so that the piston rod axis of the slide column assembly 6 forms the required angle with the wheel mounting surface of the brake assembly 3. This angle varies for different vehicle models.

[0039] like Figure 2 As shown, the positioning and clamping mechanism 2 includes a positioning mechanism 7, a brake clamping mechanism 8, a sliding column clamping mechanism 9, and an auxiliary positioning mechanism 10. The brake clamping mechanism 8 is mounted and fixed on the positioning mechanism 7, and the pressure block on the brake clamping mechanism 8 is coaxial with the arc hole of the positioning mechanism mounting seat 7.

[0040] The brake clamping mechanism 8 is installed on the track groove of the positioning clamping mechanism 2 and can move up and down along the track.

[0041] The auxiliary positioning mechanism 10 is connected to the positioning mechanism 7 via a slide rail, and the position of the auxiliary positioning mechanism 10 is adjusted according to the length of different slide column assemblies 6.

[0042] Under the action of the drive motor, the positioning and clamping mechanism 2 slides along the track to the module moving support mechanism 1. The upper surface of the positioning mechanism 7 platform engages with the rim mounting surface of the brake assembly 3. The auxiliary positioning mechanism 10 sleeve automatically drives the sliding column end positioning mechanism to move to the corresponding position according to the corresponding position information of different vehicle models. The sleeve contacts the piston rod end of the sliding column assembly 6. The brake pressing mechanism presses the brake assembly 3, and the clamping mechanism clamps the sliding column assembly 6. The fastener 5 is tightened to the required parameters. After completion, the positioning and clamping mechanism 2 returns to the initial position, and the assembled brake assembly 3 and sliding column assembly 6 are transferred to the next workstation along with the module moving support mechanism 1.

[0043] like Figure 3 As shown, the module moving support mechanism 1 includes a steering wheel bracket 11, a roller 12, a support frame 13, a brake bracket 14, a sliding column support frame 15, and a support wheel frame 16.

[0044] Roller 12 is mounted on steering wheel bracket 11 and support wheel bracket 16. The pin of steering wheel bracket 11 is mounted on support frame 13, allowing free rotation during movement. Brake bracket 14 and sliding column support frame 15 are welded to support frame 13. The relative positional relationship between brake bracket 14 and sliding column support frame 15 conforms to the design of sliding column assembly 6 and brake assembly 3 as a single unit, meeting ergonomic requirements and facilitating easy access. Support frame 13 has a reserved connection port for BEV vehicle or drive power.

[0045] like Figure 4 As shown, the positioning mechanism 7 includes a positioning mechanism seat 17, a pneumatic pressure head 18, a cylinder rod 19, a seat cushion 20, a pneumatic cylinder 21, a height adjustment device 22, a sliding column limit sleeve 23, a sliding column limit moving seat 24, a sliding column limit mounting seat 25, a sliding column limit drive cylinder 26, an auxiliary limit drive device 27, a sliding column limit rotation drive device 28, an auxiliary limit outer slide rail 29, and an auxiliary limit inner slide rail 30.

[0046] The brake assembly 3 is placed on the seat 20 of the positioning mechanism seat 17. The pneumatic cylinder 21 starts to inflate and drive the cylinder rod 19. The pneumatic pressure head 18 installed on the cylinder rod 19 presses the brake assembly 3 onto the seat 20. When the pressure is released, the control valve reverses and the pneumatic pressure seat returns to the initial position. The pneumatic cylinder 21 is installed on the positioning mechanism seat 17.

[0047] The end of the slide column assembly 6 is positioned by the slide column limiting sleeve 23, which is driven along the axis of the slide column limiting sleeve 23 by the slide column limiting drive cylinder 26. The slide column limiting drive cylinder 26 is mounted on the slide column limiting moving seat 24 and can be driven by the slide column limiting rotation drive device 28 to rotate around the slide column limiting moving seat 24 by a certain angle, which is consistent with the angle between the end faces of the slide column assembly 6 and the brake assembly 3. The height adjustment device 22 is mounted on the slide column limiting mounting seat 25, and the lead screw on the height adjustment device 22 drives the slide column limiting moving seat 24 to move up and down. According to the position of the end of the slide column assembly 6, the corresponding parameters are set in the equipment controller. During use, according to the product information input, the angle of the slide column limiting sleeve 23 is adjusted by the slide column limiting rotation drive device 28, and the height of the slide column limiting sleeve 23 is adjusted by the height adjustment device 22.

[0048] The sliding column limit mounting base 25 and the positioning mechanism base 17 can move relative to each other along the auxiliary limit outer slide rail 29 and the auxiliary limit inner slide rail 30. The auxiliary limit outer slide rail 29 is mounted on the sliding column limit mounting base 25, and the auxiliary limit inner slide rail 30 is mounted on the positioning mechanism base 17. The corresponding parameters are set in the equipment controller. During use, according to the product information input, the auxiliary limit drive device 27 drives the auxiliary limit outer slide rail 29 through the lead screw to achieve the optimal distance between the brake assembly 3 and the end of the sliding column assembly 6.

[0049] like Figure 5 As shown, the sliding column clamping mechanism 9 includes a clamping mechanism sliding drive device 31, a sliding column clamping base 32, a base positioning pin 33, a clamping upper seat 34, a clamping mechanism support 35, a clamping mechanism slider 36, a clamping upper seat drive device 37, and an upper seat drive rod 38. Before tightening, the clamping mechanism clamps the sliding column assembly 6.

[0050] The clamping mechanism sliding drive device 31 is mounted on the positioning mechanism seat 17. The base positioning pin 33 and the clamping mechanism slider 36 cooperate with the positioning mechanism seat 17. According to the corresponding position parameters of the slide column assembly 6 when the brake assembly 3 and the slide column assembly 6 are engaged, the clamping mechanism sliding drive device drives the clamping mechanism support 35 to the corresponding position. The slide column clamping mechanism 9 can move up and down relative to the positioning mechanism seat 17 to achieve positioning of different vehicle models in the corresponding positions.

[0051] After the slide column assembly 6 is placed on the slide column clamping base 32, the clamping upper seat drive device 37 drives the upper seat drive rod 38 to move upward, so that the clamping upper seat 34 presses the slide column assembly 6.

[0052] like Figure 6 As shown, the tightening auxiliary mechanism 4 includes a fastener limiter 39, a limiter working cylinder 40, a limiter movement controller 41, a drive wheel 42, a vertical slide rail 43 for the limiter working cylinder, a horizontal slide rail 44 for the limiter working cylinder, and a limiter drive device 45.

[0053] The fastener limiter 39 is driven by gas in the limiter working cylinder 40 and cooperates with the fastener 5 to prevent the fastener 5 from rotating during the tightening process.

[0054] The transverse slide rail 44 of the limiter working cylinder is mounted on the limiter working cylinder 40 and cooperates with the vertical slide rail 43 of the limiter working cylinder to achieve free lateral movement. The vertical slide rail 43 of the limiter working cylinder cooperates with the long hole rail in the positioning mechanism seat 17 to achieve up and down sliding of the vertical slide rail of the limiter within the long hole. The vertical slide rail 43 of the limiter working cylinder is restricted by the end stop to prevent it from falling out of the positioning mechanism seat 17. According to the angle requirement of the slide column assembly 6 relative to the brake assembly 3, the limiter working cylinder 40 and the upper limiter working cylinder transverse slide rail 44 rotate accordingly, and the fastener limiter 39 can restrict the rotation of the fastener 5.

[0055] The limit switch movement controller 41 controls the drive wheel 42 to move towards the brake assembly 3 and engage with the transverse slide rail 44 of the limit switch working cylinder, or the limit switch movement controller 41 controls the drive wheel 42 to move towards the other side of the brake assembly 3 and engage with the vertical slide rail 43 of the limit switch working cylinder. The drive wheel 42 cooperates with the drive shaft on the limit switch drive device 45. According to the position information of the fastener 5 of the product, the limit switch drive device 45 drives the drive wheel 42, which is adjusted by the limit switch movement controller 41 to realize the up-down and left-right movement of the limit switch working cylinder to meet the assembly requirements of different products.

[0056] When assembling the front sliding pillar module of an automobile, an integrated sub-assembly table is used to assemble the front sliding pillar and the front brake. The entire process, from sample delivery, pre-assembly, tightening, and handling, is done at the same station, which is not conducive to rapid assembly and transportation. For different vehicle models, different integrated sub-assembly tables are required for the assembly of modules with different angles of the brake and the sliding pillar piston rod.

[0057] This patent uses a modular tooling fixture design to concentrate the positioning, clamping, and tightening processes into the positioning and clamping mechanism, while feeding, batching, and initial assembly are carried out on the support mechanism. The positioning and clamping mechanism is separate from the support mechanism, and multiple support mechanisms can realize assembly line operation.

[0058] Based on the fastener positions and slide column end positions of different products, the drive device on the positioning clamping mechanism adjusts the clamp to the corresponding position.

[0059] The movement trajectory of the positioning and clamping mechanism is perpendicular to the production line trajectory of the support mechanism, and the two are used in conjunction.

[0060] The embodiments described above are merely examples of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent disclosure. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
