Description

Technical Field

[0001] The invention relates to the technical field of automobile brake control, in particular to a double-caliper automobile brake, symmetrical assembly equipment and an assembly method. Background Art

[0002] Braking is the first element of safe driving. It is a powerful braking tool when emergency stopping is required, which can slow down, stop the car and ensure safety.

[0003] In recent years, with the development of new energy vehicles, the penetration rate of new energy vehicles has become higher and higher. And because new energy vehicles use power batteries as energy storage units, and the unit density of power batteries is larger, resulting in heavier mass, the mass of new energy vehicles of the same model is greater than that of fuel vehicles, which puts higher requirements on the braking system originally used in traditional vehicles.

[0004] Existing automobile brakes mostly use disc brakes. When braking, the friction between the brake pads and the brake discs slows down and brakes the wheels. However, heavier new energy vehicles often require greater braking force, and during long-term and long-distance braking, brake thermal decay is more likely to occur, seriously affecting driving safety.

[0032] The abutment assembly also includes an elastic kit arranged between the workbench and the first supporting member.

[0033] A method for assembling a dual-caliper automobile brake using the symmetrical assembly device comprises the following steps:

[0034] Step 1: Place the two symmetrical housings of the hydraulic caliper on the No. 1 support and the No. 2 support respectively, and place the parts adapted to the housings into the housings, and assemble them using an electric wrench;

[0035] Step 2: When the components on the two housings are assembled, the lateral lifting assembly is controlled to move, thereby driving the second supporting member to move toward the first supporting member and driving the second supporting member to move away from the workbench;

[0036] Step 3: As the No. 2 support moves, the No. 2 support will deflect under the action of the rotating assembly, and the trigger assembly will be triggered to energize the electromagnetic attraction device, and the assembled shell on the No. 2 support will be adsorbed until the No. 2 support rotates 180°;

[0037] Step 4: The No. 2 supporting member continues to move, and when it moves to the top of the No. 1 supporting member, the abutment component is actuated, driving the No. 1 supporting member and the No. 2 supporting member to move laterally synchronously, and the No. 2 supporting member will move toward the No. 1 supporting member, so that the shells on the two supporting members completely overlap and fit together, and then the trigger component will control the electromagnetic attraction device to cut off the power;

[0038] Step 5: The No. 2 supporting part moves in the opposite direction until the No. 1 supporting part and the No. 2 supporting part return to their initial state. At this time, the two completely overlapping shells on the No. 1 supporting part are assembled.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] In the case of full braking due to brake thermal decay, the deflector plate can deflect and act on the two sets of oil pump structures, so that the two sets of hydraulic calipers can perform braking actions alternately, ensuring that one set of brake pads connected to the two sets of hydraulic calipers can be in a cooling state, avoiding high temperatures of the two sets of brake pads at the same time, and improving the operating stability of the brake system during driving;

[0041] After the No. 2 supporting member flips 180°, when it continues to move, the transverse plate abuts against the stopper, and can drive the No. 1 supporting member and the No. 2 supporting member to move synchronously. At this time, the projections of the No. 1 supporting member and the No. 2 supporting member on the workbench overlap, and the two shells can be positioned to ensure that they can be aligned when they fit together, which is convenient for subsequent assembly. At the same time, when the No. 2 pulley moves in the No. 3 inclined groove, the No. 2 supporting member can drive the shell connected to it to move toward the No. 1 supporting member, so that the two sets of shells can fit together, thereby improving the accuracy and speed of assembly;

[0042] When the No. 2 supporting member is flipped, the electromagnetic attraction device can be energized to adsorb the outer shell and internal components on the No. 2 supporting member, so as to avoid the separation of the No. 2 supporting member from the outer shell and the components inside the outer shell when the No. 2 supporting member is flipped 180°, thereby improving the stability of the outer shell and internal components on the No. 2 supporting member during the flipping process, and after the No. 2 supporting member drives the outer shell to fit with the outer shell on the No. 1 supporting member, the electromagnetic attraction device can automatically power off, and when the No. 2 supporting member is reset, the electromagnetic attraction device can always remain in the power-off state, which can save electricity resources on the one hand, and on the other hand, when the No. 2 supporting member moves away from the No. 1 supporting member, it will not adsorb the upper outer shell again and lift it up.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0056] See also Figure 1~Figure 4 In an embodiment of the present invention, a dual-caliper automobile brake comprises: a brake disc 1, on which two groups of hydraulic calipers 2 are arranged, and each group of the hydraulic calipers 2 is connected to a group of oil pump structures;

[0057] It also includes: a control box 3, a deflection plate 14, a drive component and a switching component, so that when the brake thermal decay occurs and full braking is applied, the deflection plate 14 can be deflected and act on the two sets of oil pump structures, so that the two sets of hydraulic calipers 2 can perform braking actions alternately, ensuring that one of the sets of brake pads connected to the two sets of hydraulic calipers 2 can be in a cooling state, avoiding high temperatures in the two sets of brake pads at the same time, and improving the operating stability of the brake system during driving.

[0058] Specifically, the control box 3 is connected to the oil pump structure, and the oil pump structure includes two hydraulic cylinder bodies 4 fixedly connected to the control box 3, and a compression column 5 is sealed and slidably installed in the hydraulic cylinder body 4, and a first pulley 15 is rotatably installed at one end of the compression column 5;

[0059] The deflection plate 14 is disposed in the control box 3, and the deflection plate 14 can cooperate with the oil pump structure to drive the hydraulic caliper 2 to move;

[0060] The driving assembly is installed in the control box 3 and connected to the deflection plate 14. When the brake pedal is stepped on, the driving assembly can drive the deflection plate 14 to move toward the oil pump structure. A follower frame 9 and a side plate 10 are provided in the control box 3. The follower frame 9 is rotatably connected to the deflection plate 14. A guide groove 902 is provided on the follower frame 9. The guide groove 902 is slidably connected to a guide member 11 installed in the control box 3.

[0061] The driving assembly includes a double-headed hydraulic cylinder 6 fixedly connected to the follower frame 9, a No. 1 slider 7 is connected to the action end of the double-headed hydraulic cylinder 6, and the No. 1 slider 7 is slidably connected to a No. 1 slide groove 901 formed on the follower frame 9, wherein the double-headed hydraulic cylinder 6 is connected to the brake pedal through another hydraulic cylinder, and when the driver steps on the brake pedal, the hydraulic cylinder connected thereto can pump hydraulic oil into the double-headed hydraulic cylinder 6, so that the action ends on both sides of the double-headed hydraulic cylinder can extend outward;

[0062] The driving assembly further includes two No. 1 inclined grooves 1001 symmetrically arranged on the side plate 10 , and the No. 1 convex shaft 8 connected to the No. 1 sliding block 7 can slide in the No. 1 inclined grooves 1001 .

[0063] When the driver steps on the brake pedal, the two action ends of the double-headed hydraulic cylinder 6 will extend outward and make the No. 1 slider 7 move away from the double-headed hydraulic cylinder 6 along the length direction of the No. 1 slide groove 901. At this time, the No. 1 cam 8 connected to the No. 1 slider 7 will also follow the movement, and the No. 1 cam 8 is slidably set in the No. 1 inclined groove 1001, so that when the two No. 1 cams 8 move away from each other, the follower frame 9 can move toward the No. 1 pulley 15 along the length direction of the guide groove 902, and when the deflection plate 14 abuts against the No. 1 pulley 15, it drives one group of compression columns 5 to move toward the inside of the hydraulic cylinder body 4, so as to squeeze the hydraulic oil in the hydraulic cylinder body 4 into the hydraulic caliper 2, so that the brake pad connected to the hydraulic caliper 2 moves toward the brake disc 1, thereby slowing down the brake disc 1 and the wheel to a stop through friction.

[0064] Among them, when the brake pedal is pressed and the deflection plate 14 moves toward the No. 1 pulley 15, when the brake pedal is pressed to the maximum depth, the deflection plate 14 just pushes one group of compression cylinders 5 to the limit state. At the same time, the deflection plate 14 is in contact with the No. 1 pulley 15 on the other group of compression cylinders 5, and there is no interaction force between the two. That is, when the brake pedal is pressed, one and only one group of hydraulic calipers 2 is in the state of performing braking action. This ensures that when the switching component drives the two groups of hydraulic calipers 2 to act alternately, one group of hydraulic calipers 2 can be kept in a non-working state, and the brake pads connected to the group of hydraulic calipers 2 can be cooled, thereby avoiding the brake pads on the two groups of hydraulic calipers 2 being in a high temperature state under long-term and long-distance braking conditions, thereby improving the braking stability under long-term and long-distance braking conditions.

[0065] See also Figure 3~Figure 4 , the switching component is connected to the driving component and the deflection plate 14, and the switching component can drive the deflection plate 14 to deflect when one group of the hydraulic calipers 2 maintains the braking action for a predetermined time, so that the two groups of the hydraulic calipers 2 perform the braking action alternately;

[0066] The switching assembly includes two driving motors 12 diagonally arranged on the follower frame 9, the output shaft of the driving motor 12 passes through the follower frame 9 and is connected to a turntable 13, a second cam shaft 1301 is fixedly installed at an eccentric position of the turntable 13, and the second cam shaft 1301 is slidably connected to a fitting groove 1401 arranged on the side of the deflection plate 14.

[0067] In the initial state, the line connecting the second cam 1301 and the central axis of the rotating disk 13 is perpendicular to the engaging groove 1401 (see the attached Figure 4), and an arc groove (not shown in the figure) is formed on the side of the middle of the engaging groove 1401 away from the rotating shaft of the turntable 13, and the arc groove is adapted to the second cam 1301, so that when the deflection plate 14 abuts against one of the first pulleys 15, the second cam 1301 cooperates with the arc groove to support the deflection plate 14, thereby avoiding the deflection plate 14 giving way and failing to brake during the pressure application process.

[0068] When the brake pedal is stepped on and the deflection plate 14 acts on one of the oil pumping structures to activate one of the hydraulic calipers 2, if brake thermal decay occurs, the driver will inevitably step on the brake pedal with all his strength. At this time, the vehicle's on-board computer will control the drive motor 12 to work according to the force with which the brake pedal is stepped on and the deceleration of the vehicle, and thereby drive the turntable 13 to rotate, thereby causing the second cam 1301 to make a circular motion. During this process, the second cam 1301 cooperates with the engaging groove 1401 to drive the deflection plate 14 to deflect, and during the deflection of the deflection plate 14, one end of the deflection plate 14 will release one of the oil pumping structures, and the other end will apply pressure to the other oil pumping structure, so that the two groups of hydraulic calipers 2 connected thereto can switch the braking action, so that the brake pads that were originally heated up due to friction can be cooled, thereby avoiding brake failure caused by brake thermal decay.

[0069] Among them, under the condition of full braking, one side of the deflection plate 14 can act on one group of No. 1 pulleys 15, so that the matched hydraulic caliper 2 performs the maximum braking force, and the other side will be attached to the other group of No. 1 pulleys 15. In this state, if the deflection plate 14 is deflected, the two groups of No. 1 pulleys 15 will perform completely opposite actions, so that the brake pads connected to the two groups of hydraulic calipers 2 can perform completely opposite actions, thereby ensuring that when the two hydraulic calipers 2 perform the switching action, the total force of the two groups of brake pads on the brake disc 1 is constant, and considering the thermal attenuation, the braking force is increased, thereby improving the braking stability during the switching process.

[0070] Through the above-mentioned arrangement, when full braking occurs due to brake thermal decay, the deflector plate 14 can be deflected and act on the two sets of oil pump structures, so that the two sets of hydraulic calipers 2 can perform braking actions alternately, ensuring that one of the sets of brake pads connected to the two sets of hydraulic calipers 2 can be in a cooling state, avoiding high temperatures in the two sets of brake pads at the same time, and improving the operating stability of the brake system during driving.

[0071] It should be noted that when the drive motor 12 is working, it can drive the turntable 13 to rotate half a circle at a time, and during long-term use, the on-board computer can control the action of the drive motor 12, so that when the brake pedal is used normally, the two sets of hydraulic calipers 2 can operate alternately to avoid the situation where the brake pads on the two sets of hydraulic calipers 2 have excessively different wear.

[0072] See also Figure 5~Figure 10 As an embodiment of the present invention, a symmetrical assembly device is also proposed for assembling the dual-caliper automobile brake, comprising: a workbench 16, a deflection mechanism, an abutment assembly and a trigger assembly.

[0073] The workbench 16 is provided with a first supporting member 17 and a second supporting member 18, and an electromagnetic attraction device 19 is installed at the bottom of the second supporting member 18;

[0074] The deflection mechanism is disposed on the workbench 16 and connected to the second support member 18. The deflection mechanism includes a transverse lifting assembly and a rotation assembly. The transverse lifting assembly cooperates with the rotation assembly to enable the second support member 18 to rotate 180° when the second support member 18 is driven to move toward the first support member 17.

[0075] The workbench 16 is provided with a third slide 1602;

[0076] The transverse lifting assembly includes a transverse plate 20 rotatably connected to the second supporting member 18, a second slider 21 is slidably mounted on the transverse plate 20, specifically, the second slider 21 is slidably connected to a fourth slide groove 2001 arranged along the length direction of the transverse plate 20, and an engaging wheel 2101 is rotatably mounted on the second slider 21, and the engaging wheel 2101 is rollingly connected to an inner embedded groove arranged on the inner side of the third slide groove 1602;

[0077] The second slide block 21 is connected to the trigger assembly via a connecting frame 30, and the connecting frame 30 is connected to a linear drive module 37 disposed on the workbench 16;

[0078] The transverse lifting assembly also includes a sheave structure arranged between the workbench 16 and the transverse plate 20, the sheave structure includes a No. 1 guide plate 29 arranged on the workbench 16, a No. 1 horizontal groove 2902 is arranged on the No. 1 guide plate 29, the end of the No. 1 horizontal groove 2902 is connected to a No. 2 inclined groove 2901 and a No. 3 inclined groove 2903, and the No. 2 pulley 28 rotatably mounted on the transverse plate 20 can roll in the No. 2 inclined groove 2901, the No. 1 horizontal groove 2902 and the No. 3 inclined groove 2903;

[0079] The rotating assembly includes a gear 23 rotatably mounted on the transverse plate 20, the gear 23 is connected to the rotating shaft of the second supporting member 18 through a transmission belt 22, and the gear 23 is adapted to a rack plate 24 provided on the first guide plate 29;

[0080] The rotating assembly further includes a stopper 25 coaxially fixedly connected to the rotating shaft of the second supporting member 18, and the stopper 25 is provided with two symmetrical stopper grooves 2501, and the elastic abutment structure connected to the transverse plate 20 is adapted to the stopper 25, and the elastic abutment structure includes an elastic telescopic rod 27 and an abutment wheel 26 provided on the transverse plate 20;

[0081] When in use, the two shells of the hydraulic caliper 2 are placed on the No. 1 supporting member 17 and the No. 2 supporting member 18 respectively, and the parts that need to be assembled on the two shells are assembled. After the assembly is completed, the linear drive module 37 is controlled to move. At this time, the linear drive module 37 will drive the connecting frame 30 and the No. 2 slider 21 to move along the length direction of the No. 3 slide groove 1602 toward the No. 1 supporting member 17, and drive the transverse plate 20 to move. In the initial state, the No. 2 pulley 28 on the transverse plate 20 is in the No. 2 inclined groove 2 901 is away from one end of the first horizontal groove 2902, so that when the transverse plate 20 moves, the second pulley 28 can move along the length direction of the second inclined groove 2901, so as to drive the second supporting member 18 to move upwardly through the transverse plate 20, and when the second pulley 28 moves into the first horizontal groove 2902, as the transverse plate 20 moves horizontally, the gear 23 will mesh with the rack plate 24, so that the gear 23 rotates, and at this time, the gear 23 can drive the rotating shaft of the second supporting member 18 to rotate through the transmission belt 22;

[0082] And in the initial state, the abutment wheel 26 abuts against one of the limit grooves 2501. When the limit member 25 rotates, the abutment wheel 26 can be separated from the limit groove 2501, and when the gear 23 is meshed with the rack plate 24 and drives the gear 23 to rotate until the gear 23 and the rack plate 24 are separated, the elastic telescopic rod 27 can drive the abutment wheel 26 to abut against another limit groove 2501 on the limit member 25 by releasing elastic potential energy, so that during the flipping process of the No. 2 supporting member 18, its flipping angle can be positioned and limited, ensuring that during the process of the gear 23 and the rack plate 24 cooperating once, the No. 2 supporting member 18 can be flipped just 180° (due to the adsorption of the electromagnetic attraction device 19, the shell on the No. 2 supporting member 18 will not fall off), so that the shell on the No. 2 supporting member 18 can open downward.

[0083] Through the above arrangement, during the movement of the No. 2 supporting member 18 toward the No. 1 supporting member 17, it can first move away from the workbench 16 and then perform the flipping action, thereby avoiding interference between the No. 2 supporting member 18 and the workbench 16 during the rotation process, and with the cooperation of the abutment wheel 26 and the limiting groove 2501, it can be ensured that the No. 2 supporting member 18 can be flipped 180° during the process of the gear 23 and the rack plate 24 cooperating once, so that the shell on the No. 2 supporting member 18 can open downward.

[0084] See also Figure 5 , Fig.10 The abutment assembly connects the transverse movement lifting assembly and the No. 1 support member 17. When the No. 2 support member 18 moves toward the No. 1 support member 17 to the end of the stroke, the abutment assembly can drive the No. 1 support member 17 and the No. 2 support member 18 to move transversely synchronously;

[0085] The abutment assembly includes a stopper 1701 formed on the side of the first support member 17, and the stopper 1701 is adapted to the transverse plate 20;

[0086] The abutment assembly also includes an elastic kit arranged between the workbench 16 and the No. 1 supporting member 17, and the elastic kit includes a No. 2 slide groove 1601 arranged on the workbench 16, and a No. 3 slider 34 fixedly connected to the No. 1 supporting member 17 is slidably installed in the No. 2 slide groove 1601, and the No. 3 slider 34 is slidably connected to the horizontal axis 35 arranged in the No. 2 slide groove 1601, and a spring 36 is sleeved on the horizontal axis 35, one end of the spring 36 is connected to the No. 3 slider 34, and the other end is connected to the side of the No. 2 slide groove 1601.

[0087] After the No. 2 supporting member 18 flips 180°, the No. 2 pulley 28 will continue to move horizontally in the No. 1 horizontal groove 2902, and when the No. 2 pulley 28 moves to the end of the stroke of the No. 1 horizontal groove 2902, the transverse plate 20 will abut against the stopper 1701 on the side of the No. 1 supporting member 17. At this time, the projections of the No. 1 supporting member 17 and the No. 2 supporting member 18 on the workbench 16 coincide, and during the subsequent transverse movement of the transverse plate 20, it can drive the No. 1 supporting member 17 and the No. 2 supporting member 18 to move horizontally synchronously, and during the transverse movement of the No. 1 supporting member 17, the spring 36 will be compressed.

[0088] Specifically, during the synchronous horizontal transverse movement of the No. 1 supporting member 17 and the No. 2 supporting member 18, the No. 2 pulley 28 will move along the No. 3 inclined groove 2903, so that during the synchronous horizontal transverse movement of the No. 1 supporting member 17 and the No. 2 supporting member 18, the two maintain relative stillness of the lateral displacement, and at the same time, the No. 2 supporting member 18 will move toward the No. 1 supporting member 17, so that the outer shell on the No. 2 supporting member 18 can overlap with the outer shell on the No. 1 supporting member 17, and then the outer shell on the No. 2 supporting member 18 can move toward the No. 1 supporting member 17, until the two outer shells on the hydraulic caliper 2 can fit together, thereby avoiding friction and wear between the fitting surfaces of the two sets of outer shells.

[0089] Through the above arrangement, after the No. 2 supporting member 18 flips 180°, when it continues to move, the transverse plate 20 abuts against the stopper 1701, and can drive the No. 1 supporting member 17 and the No. 2 supporting member 18 to move synchronously. At this time, the projections of the No. 1 supporting member 17 and the No. 2 supporting member 18 on the workbench 16 overlap, and the two shells can be positioned to ensure that they can be aligned when they are fitted, which is convenient for subsequent assembly. At the same time, when the No. 2 pulley 28 moves in the No. 3 inclined groove 2903, the No. 2 supporting member 18 can drive the shell connected to it to move toward the No. 1 supporting member 17, so that the two groups of shells can fit together, thereby improving the accuracy and speed of assembly.

[0090] See also Figure 6 , Figure 7 , Fig. 9 The trigger assembly is connected to the transverse lifting assembly and is electrically connected to the electromagnetic attraction device 19. The trigger assembly can energize the electromagnetic attraction device 19 when the second supporting member 18 rotates, and de-energize the electromagnetic attraction device 19 when the first supporting member 17 and the second supporting member 18 move to the end of the stroke;

[0091] The trigger assembly includes a trigger switch 31 fixedly connected to the connecting frame 30, the trigger switch 31 is electrically connected to the electromagnetic attraction device 19, and a third pulley 32 is rotatably mounted on the trigger end of the trigger switch 31;

[0092] The trigger assembly further includes a second guide plate 33 disposed on the workbench 16, a switching groove is formed on the second guide plate 33, and the third pulley 32 can roll in the switching groove, and the switching groove includes a second horizontal groove 3302 and a third horizontal groove 3304 disposed on the second guide plate 33 and parallel to each other, one end of the two is connected through the vertical groove 3303, and the other end is connected through the fourth inclined groove 3305;

[0093] An extension slot 3301 is provided at one end of the second horizontal slot 3302 away from the vertical slot 3303 , and a switching plate 3306 is rotatably mounted at one end of the fourth inclined slot 3305 away from the third horizontal slot 3304 .

[0094] When the linear drive module 37 drives the connecting frame 30 to move horizontally, the connecting frame 30 can drive the trigger switch 31 to move synchronously with the transverse plate 20. In the initial state, the third pulley 32 on the trigger switch 31 is at the end of the extension slot 3301 away from the switching plate 3306. At this time, the trigger switch 31 is in an unactivated state. As the connecting frame 30 moves, when the second pulley 28 moves into the first horizontal slot 2902 and the gear 23 is meshed with the rack plate 24, the third pulley 32 is moved to the horizontal slot 2902. The switching plate 3306 is guided into the No. 4 inclined groove 3305 and moves to the end of the No. 4 inclined groove 3305, so that the No. 3 pulley 32 can move toward the connecting frame 30 and the trigger switch 31 is turned on. At this time, the electromagnetic attraction device 19 is energized, and the outer shell and internal components of the No. 2 supporting member 18 can be adsorbed, thereby ensuring that when the No. 2 supporting member 18 is flipped 180°, the outer shell and internal components of the No. 2 supporting member 18 will not be separated from the No. 2 supporting member 18.

[0095] It should be noted that the trigger switch 31 needs to be triggered before the gear 23 engages with the rack plate 24 and the No. 2 support member 18 flips 45°, so as to avoid the No. 2 support member 18 flipping at too large an angle, causing the outer shell and internal components of the No. 2 support member 18 to overturn before the electromagnetic attraction device 19 works.

[0096] After the trigger switch 31 is energized, the third pulley 32 will move along the third horizontal groove 3304, and at the same time, the second support member 18 continues to perform the actions of flipping, lateral movement, and synchronous movement with the first support member 17, and when the second support member 18 drives the shell and its internal components to fit with the shell and its internal components on the second support member 18, the third pulley 32 just moves to the end of the third horizontal groove 3304, and at this time, the built-in spring of the trigger switch 31 can drive the third pulley 32 to move along the vertical groove 3303. The trigger switch 31 is powered off, and then the linear drive module 37 drives the connecting frame 30 to move in the reverse direction, and the above process is reversed. However, when the above action is reversed, the third pulley 32 will move along the second horizontal groove 3302 to the extension groove 3301. During this process, the electromagnetic attraction device 19 is always in a power-off state. On the one hand, it can save electricity resources, and on the other hand, when the second supporting member 18 moves away from the first supporting member 17, it will not absorb the upper shell again and lift it up.

[0097] When the third pulley 32 abuts against the switching plate 3306, the switching plate 3306 can be driven to deflect, and when the third pulley 32 moves into the extension slot 3301 and separates from the switching plate 3306, the switching plate 3306 will automatically reset under the action of gravity.

[0098] When the No. 1 supporting member 17 and the No. 2 supporting member 18 are reset, the two shells that have been positioned and fitted together are located on the No. 1 supporting member 17. At this time, the two sets of shells can be connected by assembly.

[0099] Through the above arrangement, when the No. 2 supporting member 18 is flipped, the electromagnetic attraction device 19 can be energized to adsorb the outer shell and internal components on the No. 2 supporting member 18, so as to avoid the separation of the No. 2 supporting member 18 from the outer shell and the components inside the outer shell when the No. 2 supporting member 18 is flipped 180°, thereby improving the stability of the outer shell and internal components on the No. 2 supporting member 18 during the flipping process, and after the No. 2 supporting member 18 drives the outer shell to fit with the outer shell on the No. 1 supporting member 17, the electromagnetic attraction device 19 can automatically power off, and when the No. 2 supporting member 18 is reset, the electromagnetic attraction device 19 can always remain in the power-off state, which can save electricity resources on the one hand, and on the other hand, when the No. 2 supporting member 18 moves away from the No. 1 supporting member 17, it will not adsorb the upper outer shell again and lift it up.

[0100] Furthermore, the action of the electromagnetic attraction device 19 and the lateral movement and flipping of the second support member 18 have a mechanical interlocking effect, which makes the device more integrated and easier to operate. Compared with the prior art method of using sensors to work together, the mechanical structure has better stability and lower latency.

[0101] A method for assembling a dual-caliper automobile brake using the symmetrical assembly device as described, comprising the following steps:

[0102] Step 1: Place the two symmetrical shells of the hydraulic caliper 2 on the No. 1 supporting member 17 and the No. 2 supporting member 18 respectively, and place the parts adapted to the shells into the shells, and assemble them using an electric wrench;

[0103] Step 2: After the components on the two housings are assembled, the lateral lifting assembly is controlled to move, thereby driving the second supporting member 18 to move toward the first supporting member 17 and driving the second supporting member 18 to move away from the workbench 16;

[0104] Step 3: As the second supporting member 18 moves, the second supporting member 18 will deflect under the action of the rotating assembly, and the trigger assembly will trigger the electromagnetic attraction device 19 to energize, and the assembled shell on the second supporting member 18 will be adsorbed until the second supporting member 18 rotates 180°;

[0105] Step 4: The second supporting member 18 continues to move, and when it moves to the top of the first supporting member 17, the abutment assembly is actuated, driving the first supporting member 17 and the second supporting member 18 to move laterally synchronously, and the second supporting member 18 will move toward the first supporting member 17, so that the shells on the two are completely overlapped and attached, and then the trigger assembly will control the electromagnetic attraction device 19 to cut off the power;

[0106] Step 5: The No. 2 supporting member 18 moves in the opposite direction until the No. 1 supporting member 17 and the No. 2 supporting member 18 return to their initial state. At this time, the two completely overlapping shells on the No. 1 supporting member 17 are assembled.
