Description

Technical Field

[0001] The present application relates to the field of brake processing equipment, and in particular to a brake assembly machine and an assembly process thereof. Background Art

[0002] A brake is a device that has the function of slowing down, stopping or keeping a moving part (or moving machinery) in a stopped state; it is a mechanical part that stops or slows down the moving parts in the machinery.

[0003] When assembling the brake, the bearing needs to be installed in the housing with wires, and then the semi-assembly parts of the flange and spline shaft need to be installed on the housing and assembled with the bearing in the housing. Therefore, assembling the brake requires going back and forth between several assembly equipment and testing equipment, which has low assembly efficiency and needs to be improved. Summary of the Invention

[0004] In order to improve the assembly efficiency of the brake, the present application provides a brake assembly machine and an assembly process thereof.

[0005] In the first aspect, the brake assembly machine provided by this application adopts the following technical solutions:

[0006] A brake assembly machine comprises a machine body, a workbench is provided on the machine body, a work disk is rotatably provided on the workbench, a number of assembly stations are evenly arranged on the work disk along its circumference, a bearing loading area, a shell loading area, a semi-assembly loading area and a unloading area are provided on the workbench, a bearing loading mechanism is provided on the workbench where it is located in the bearing loading area, and a unloading mechanism is provided on the workbench where it is located in the unloading area; the bearing loading area, shell loading area, semi-assembly loading area and unloading area are arranged in sequence along the circumference of the work disk to correspond to the assembly stations; a pressing mechanism is provided between the shell loading area and the semi-assembly loading area, and between the semi-assembly loading area and the unloading area, and detection parts are provided between each of the bearing loading area, shell loading area, semi-assembly loading area and unloading area.

[0007] By adopting the above technical solution, when the brake assembly machine begins operation, the bearing loading mechanism places the bearing on an assembly station in the bearing loading area. For convenience, the assembly station where the bearing is placed is referred to as a processing station. The work disk rotates circumferentially. When a processing station moves to the next station, it is inspected by a test piece to determine whether the bearing is properly positioned within the processing station. If the inspection passes, the machine moves to the next station, the housing loading area. There, the housing with the electrical wiring is placed in the processing station and fitted over the bearing. The work disk continues to move, and when the processing station moves to the next station, the pressing mechanism presses the housing and bearing together and inspects the assembly for compliance using a test piece. If the inspection passes, the processing station moves to the next station, the semi-assembly loading area. A semi-assembly consisting of a flange and a splined shaft is placed on top of the housing, and the splined shaft is then inserted into the bearing. The work disk continues to move, and when the processing station moves to the next station, the pressing mechanism assembles the semi-assembly, housing, and bearing, and inspects the assembly for compliance using a test piece. If the inspection passes, the processing station moves to the next station, the unloading area, where the unloading mechanism unloads the qualified brake. The worktable continues to move, and when the processing station moves to the next station, the inspection component verifies whether the brake assembled in the processing station has been unloaded cleanly. If the inspection passes, it means that the unloading is clean, and the processing station can move again to the bearing loading area to complete the above cycle process.

[0008] The various parts required for the brake are assembled in sequence on the assembly machine. At the same time, the assembly gaps of each part are used to achieve pressing or testing when assembling other brakes, so that multiple brakes can be assembled at the same time, thereby improving the assembly efficiency of the brake.

[0009] Optionally, an assembly plate is provided on each assembly station, and the assembly plate is raised and lowered on the work disk along the height direction. An assembly cavity is provided on the top wall of the assembly plate, and a storage piece for storing wires is also provided on the top wall of the assembly plate.

[0010] Optionally, the storage component includes a connecting plate, a fixed vertical plate and a clamping vertical plate, the connecting plate is connected to the assembly plate, the fixed vertical plate is arranged on the connecting plate, the clamping vertical plate is rotatably connected to the connecting plate through a torsion spring, and an area for placing the power supply line is formed between the clamping vertical plate and the fixed vertical plate.

[0011] By adopting the above technical solution, when the shell with wires is placed in the assembly cavity, the wires have been wound and tied in advance in the previous process, so the wires only need to be placed between the clamping vertical plate and the fixed vertical plate to be fixed, which can reduce the impact of the wires on the rotation of the working disk.

[0012] Optionally, the workbench is located in the shell loading area and is provided with a shell loading mechanism, the shell loading mechanism includes a shell loading robot, a lower pressure plate, a straightening rod and a shell storage assembly, the shell storage assembly is installed on the workbench, the outlet end of the shell storage assembly is close to the working disk, the shell loading robot moves back and forth between the outlet end of the shell storage assembly and the shell loading area, the straightening rod is slidably installed on the shell loading robot, the straightening rod moves in the horizontal direction, the lower pressure plate is fixedly installed on the shell loading robot, and the lower pressure plate is located above the straightening rod.

[0013] Optionally, the shell storage assembly includes a shell storage cavity and a guide cavity, the shell storage cavity is installed at an angle on the workbench, the shell storage cavity is tilted downward toward the direction of the shell loading robot, and the guide cavity is installed on one side of the shell storage cavity and has the same tilt direction; the side wall of the shell storage cavity in contact with the guide cavity is provided with a guide long hole along the tilt direction, and notches are provided at both ends of the shell storage cavity and the guide cavity, and the shell loading robot picks up the shell from the notch of the shell storage cavity.

[0014] By adopting the above technical solution, the shell loading robot picks up the shell from the gap of the shell storage cavity. At this time, the wires of the shell sag under the action of gravity and stick to the side wall of the lower pressure plate.

[0015] During the movement of the shell loading robot toward the assembly cavity, the straightening rod moves along the width direction of the shell storage cavity. At this time, the shell wires change from a drooping state to an approximately parallel state of the wound part of the wires under the movement of the straightening rod. At this time, the shell wires are attached to the bottom wall of the lower pressure plate. At the same time, the shell robot has moved the shell to the top of the assembly cavity at the shell loading area.

[0016] The shell loading robot moves downward to place the shell in the transfer cavity, and the lower pressure plate presses the wires between the fixed vertical plate and the clamping vertical plate. At this time, one end of the lower pressure plate is inserted between the holding vertical plate and the fixed vertical plate; at the same time, the straightening rod has moved from one side of the fixed vertical plate to the other side, that is, when the shell loading robot descends, the straightening rod and the fixed vertical plate cannot collide.

[0017] The shell is also loaded automatically, and the position of the wires during the shell assembly process is fixed during the loading process, which further improves the assembly efficiency of the brake and reduces labor.

[0018] Optionally, the bearing loading mechanism includes a bearing loading robot and a bearing storage assembly, the bearing storage assembly is arranged on the workbench, and the outlet end of the bearing storage assembly is close to the bearing loading area; the bearing loading robot is installed on the workbench, and the bearing loading robot reciprocates between the outlet end of the bearing storage assembly and the bearing loading area to place the bearing on the assembly station at the bearing loading area.

[0019] Optionally, the bearing storage assembly includes a storage base plate, several storage cavities, a push plate and a push block, the storage base plate is installed on a workbench, a plurality of storage slots are provided on the top wall of the storage base plate, one end of several storage cavities is inserted into the storage slot, a limit strip is provided on the storage base plate, and a limit hole for the storage cavity to pass through is provided on the limit strip; a push hole is provided on the side wall of the storage cavity at one end of the storage slot, and the push hole is communicated with the storage slot; a plurality of push slots are provided on the side wall of the storage base plate, each of the push slots is communicated with a storage slot, and the push plate is close to one side of the storage base plate A plurality of notches are provided to form a plurality of pushing strips, which are inserted into the pushing trough. The pushing strips move back and forth in the storage trough to push the bearing in the direction away from the pushing strips; a pushing chute is provided on the side of the storage substrate away from the pushing trough, and several of the pushing chutes are connected. The pushing block moves back and forth in the plurality of pushing chutes to push the bearing in the direction of the bearing loading robot, and the pushing block is connected to a reciprocating moving part; an extension plate is provided on the side of the storage substrate close to the bearing loading robot, and an extension groove is provided on the top wall of the extension plate, which is consistent with the axis direction of the pushing chute and is connected to the pushing chute to form an outlet end.

[0020] By adopting the above technical solution, the bearings stored in the storage cavity fall to the storage hole under the action of gravity, and the pushing bar moves in the pushing groove toward one end of the working disk under the action of the cylinder. The pushing bar pushes the bearing located in the pushing hole in the storage cavity out of the storage cavity and finally pushes it into the pushing chute.

[0021] At this time, several pushed-out bearings are scattered in each pushing chute. The pushing block pushes the bearings pushed by the pushing bar into the pushing chute into the extension groove. The bearing loading robot takes the bearings at the outlet end of the extension groove and places them in the assembly cavity.

[0022] Each time the bearing loading robot removes a bearing, the pusher pushes the remaining bearings forward one bearing position, ensuring that there is always a bearing at the outlet of the extension plate for the bearing loading robot to remove. The bearing loading robot places the bearing at the outlet of the extension plate into the assembly cavity of the bearing loading area.

[0023] Optionally, the material storage substrate is provided with a pressure plate at the pushing chute, and a pressure waist hole is opened on the pressure plate along the moving direction of the bearing. The pushing block passes through the pressure hole and moves back and forth in the pressure waist hole. The width of the pressure waist hole is smaller than the diameter of the bearing.

[0024] By adopting the above technical solution, when the push block pushes the bearing toward the extension plate, the pressure plate limits the bearing in the height direction, making it difficult for the bearing to deviate during the pushing process, so that the bearing can be smoothly pushed to the outlet end.

[0025] Optionally, the unloading mechanism includes a unloading robot and a unloading transport component, the inlet end of the unloading transport component is close to the unloading area, and the outlet end is located outside the machine body; the unloading robot is installed on the workbench and moves back and forth between the unloading area and the inlet section of the unloading transport component.

[0026] In a second aspect, the brake assembly process using the brake assembly machine provided in this application adopts the following technical solutions:

[0027] A brake assembly process using a brake assembly machine comprises the following steps:

[0028] The bearing loading mechanism places the bearing on the assembly station located in the bearing loading area. The work plate rotates to move the assembly station with the bearing to the inspection part for inspection to determine whether the bearing is in place.

[0029] After the bearing position is tested and qualified, the work disk continues to rotate. When the assembly station with the bearing moves to the shell loading area, the shell with the wires is placed on the assembly station and sleeved on the outside of the bearing.

[0030] The work disc continues to rotate to the next station, and the bearing with the housing is pressed together by the pressing mechanism, so that the housing and the bearing are assembled. The assembled housing and bearing are then inspected using a detection component to determine whether the housing and the bearing are installed in place.

[0031] After the housing and bearings are inspected and installed, the worktable continues to rotate. When the assembly station with the housing and bearings moves to the semi-assembly loading area, the semi-assembly with the flange and spline shaft is placed on the housing, and one end of the spline shaft is inserted into the bearing.

[0032] The work disc continues to rotate to the next station, where the semi-assembled parts with flanges and spline shafts are pressed onto the housing and bearings to complete the assembly of the brake. The inspection component tests the assembled brake to determine whether the assembly is stable. The qualified brakes are moved to the unloading area by the rotating work disc, and the unloading mechanism removes and collects the qualified brakes.

[0033] The assembly station for removing the brake continues to move to the next station under the rotation of the work disc, and is inspected by the inspection part at this station to determine whether the brake in the assembly station is completely removed. The assembly station that passes the inspection moves again to the initial bearing loading area under the rotation of the work disc to complete the cycle assembly work.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. The various parts required for the brake are assembled in sequence on the assembly machine. At the same time, the assembly gaps of each part are used to achieve press-fitting or testing during the assembly of other brakes, enabling multiple brakes to be assembled simultaneously, thereby improving the assembly efficiency of the brake;

DETAILED DESCRIPTION

[0047] The following is combined with Figure 1-9 This application is described in further detail.

[0048] The embodiment of the present application discloses a brake assembly machine. Figure 1 The brake assembly machine includes a body 1, on which a workbench 11 is fixedly installed, on which a work disk 12 is rotatably arranged, and on which a plurality of assembly stations are arranged. In this embodiment, there are eight assembly stations; the eight assembly stations are evenly installed on the top wall of the work disk 12 along the circumference of the work disk 12.

[0049] Reference Figure 1 and Figure 2 The workbench 11 is equipped with a bearing loading area 2, a housing loading area 3, a semi-assembly loading area 4, and a blanking area 5. These areas are arranged sequentially along the circumference of the work disk 12. A bearing loading mechanism 6 is located in the bearing loading area 2 of the workbench 11, and a blanking mechanism 7 is located in the blanking area 5 of the workbench 11. Pressing mechanisms are installed between the housing loading area 3 and the semi-assembly loading area 4, and between the semi-assembly loading area 4 and the blanking area 5. Inspection components are installed between each of the bearing loading area 2, the housing loading area 3, the semi-assembly loading area 4, and the blanking area 5.

[0050] For differentiation, the inspection component between the bearing loading area 2 and the housing loading area 3 is designated as inspection component one 16. The pressing mechanism between the housing loading area 3 and the semi-assembly loading area 4 is designated as pressing mechanism one 17, and the inspection component located between the housing loading area 3 and the semi-assembly loading area 4 is mounted on pressing mechanism one 17. The pressing mechanism between the semi-assembly loading area 4 and the unloading area 5 is designated as pressing mechanism two 18, and the inspection component located between the semi-assembly loading area 4 and the unloading area 5 is mounted on pressing mechanism two 18. The inspection component between the unloading area 5 and the bearing loading area 2 is designated as inspection component two 19.

[0051] In this embodiment, the detection parts are composed of a detection probe and a cylinder; the pressing mechanisms are composed of a cylinder and a pressing rod.

[0052] When the brake assembly machine begins operation, the bearing loading mechanism 6 places the bearing on the assembly station in the bearing loading area 2. For convenience, the assembly station where the bearing is placed is referred to as the processing station. The work disk 12 rotates circumferentially. When the processing station moves to the next station, it is inspected by the inspection component 16 to determine whether the bearing is properly placed in the processing station. If the inspection passes, it moves to the next station, the housing loading area 3. The housing with the wires is placed in the processing station in the housing loading area 3 and sleeved onto the outside of the bearing. The work disk 12 continues to move. When the processing station is moved to the next station, the pressing mechanism 17 presses the housing and bearing together and assembles them, and the inspection component is used to check whether the assembly is qualified. If the inspection passes, the processing station moves to the next station, the semi-assembly loading area 4. The semi-assembly consisting of the flange and spline shaft is placed on the top of the housing. At this time, the spline shaft is inserted into the bearing. As the worktable 12 continues to move, moving the processing station to the next station, the second pressing mechanism 18 assembles the semi-assembly, housing, and bearing, and uses a test piece to verify that the assembly is qualified. If qualified, the processing station moves to the next station, the unloading area 5, where the unloading mechanism 7 unloads the qualified brake. As the worktable 12 continues to move, moving the processing station to the next station, the second test piece 19 verifies that the assembled brake in the processing station has been unloaded cleanly. If qualified, the processing station can move again to the bearing loading area 2, completing the above cycle.

[0053] The brake assembly machine goes through eight processes: loading, testing, re-loading, press-fit testing, re-loading, re-press-fit testing, unloading, and testing.

[0054] Reference Figure 2The workbench 11 includes a base 111 and a top 112. The base 111 is fixed to the machine body 1 by bolts. A pin is fixedly connected to the middle of the base 111. The pin is a positioning pin. The end of the pin away from the workbench 11 is fixedly connected to the top 112 by bolts, and the working disk 12 is rotatably connected to the positioning pin.

[0055] Reference Figure 2 and Figure 3 Each assembly station is equipped with an assembly plate 13. The worktable 12 is located on the assembly plate 13 and has four guide rails. These rails form a rectangular area, and the assembly plate 13 passes through the rails and moves up and down along them. Each guide rail is fitted with a spring, one end of which contacts the assembly plate 13 and the other end contacts the worktable 12. The spring is always compressed under the action of gravity.

[0056] An assembly cavity 14 is fixed to the top wall of the assembly plate 13 by bolts. The top of the assembly cavity 14 is open, and a first clearance gap 141 is opened on the side of the assembly cavity 14 away from the center of the working disk 12. The first clearance gap 141 is communicated with the top wall of the assembly cavity 14.

[0057] The top wall of the assembly plate 13 is also provided with a receiving member 15, which is located on the side of the assembly cavity 14 near the first clearance notch 141. The receiving member 15 includes a connecting plate 151, which is fixedly connected to the assembly plate 13 via bolts. A fixed vertical plate 152 is vertically provided on the top wall of the connecting plate 151 near the assembly cavity 14. The fixed vertical plate 152 and the connecting plate 151 are integrally formed. A second clearance notch 1521 is defined on the top wall of the fixed vertical plate 152, and the axes of the first clearance notch 141 and the second clearance notch 1521 are collinear.

[0058] A clamping riser 153 is vertically mounted on the top wall of the connecting plate 151 on the side away from the assembly cavity 14. A notch is defined in the sidewall of the connecting plate 151 on the side away from the assembly cavity 14. One end of the clamping riser 153 is inserted into the notch and is rotationally connected to the connecting plate 151 via a pin and a torsion spring. An area for placing power lines is formed between the clamping riser 153 and the fixed riser 152. The sidewalls of the clamping riser 153 and the fixed riser 152 adjacent to each other are symmetrically recessed inward to form wavy sidewalls. The top walls of both the clamping riser 153 and the fixed riser 152 are chamfered to form guide arcs.

[0059] When the shell with wires is placed in the assembly cavity 14, the wires have been wound and tied in advance in the previous process, so the wires only need to be placed between the clamping vertical plate 153 and the fixed vertical plate 152 to be fixed, which can reduce the impact of the wires on the rotation of the working disk 12.

[0060] Reference Figure 2 and Figure 4 The bearing loading mechanism 6 includes a bearing loading robot 61, which is installed on the top platform 112. In this embodiment, the bearing loading robot 61 is composed of multiple cylinders and pneumatic clamps. In other embodiments, the bearing loading robot 61 can also be implemented by other structures known to people in this field.

[0061] A bearing storage assembly 62 is provided on the base 111. A bearing loading robot 61 takes the bearings stored in the bearing storage assembly 62 to the assembly station at the bearing loading area 2. The bearing storage assembly 62 includes a storage base plate 621, which is fixed to the base 111 via straight rods. The height of the storage base plate 621 corresponds to the assembly station, and the direction of the storage base plate 621 toward the bearing loading robot 61 is the length direction of the storage base plate 621.

[0062] Reference Figure 5 and Figure 6 The top wall of the storage base plate 621 is provided with a plurality of storage slots 6211 along the length direction, and the plurality of storage slots 6211 are evenly arranged on the storage base plate 621. Each storage slot 6211 is provided with a storage cavity 622, and the length direction of the storage cavity 622 is the vertical direction. A limiting bar 625 is sleeved on the plurality of storage cavities 622. In this embodiment, there is only one limiting bar 625, and the limiting bar 625 is provided with a plurality of limiting holes 6251 along the length direction. One end of each storage cavity 622 is inserted into the storage slot 6211 through the corresponding limiting hole 6251. At this time, the side wall of the limiting bar 625 located at the limiting hole 6251 is in contact with the side wall of the storage cavity 622, thereby limiting the storage cavity 622.

[0063] In this embodiment, a gap is opened along the length direction on the side of the storage cavity 622 away from the working disk 12 so that the operator can check the number of bearings in the storage cavity 622 at any time, and the width of the gap is smaller than the diameter of the bearing to prevent the bearing from falling out of the gap.

[0064] The storage cavity 622 is inserted into the side wall of one end of the storage trough 6211 and is penetrated by a pushing hole 6221. The pushing hole 6221 is communicated with the storage trough 6211, and the opening direction of the pushing hole 6221 is consistent with the width direction of the storage substrate 621; the opening width of the pushing hole 6221 is greater than or equal to the diameter of the bearing, and the bearing can be removed from the storage cavity 622 through the pushing hole 6221.

[0065] Reference Figure 5 and Figure 6The storage base plate 621 has a plurality of pusher slots 6212 on the side facing away from the work plate 12. The pusher slots 6212 are evenly spaced along the length of the storage base plate 621, and each pusher slot 6212 communicates with a storage slot 6211. A pusher plate 623 is provided on the side of the storage base plate 621 facing away from the work plate 12. The pusher plate 623 has a plurality of notches on the side near the storage base plate 621 to form a plurality of pusher strips 6231. Each pusher strip 6231 is inserted into a pusher slot 6212.

[0066] A cylinder is fixed to the bottom wall of the storage base plate 621 by bolts, and the piston rod of the cylinder is connected to one end of the push plate 623 protruding from the push groove 6212. The cylinder drives the push plate 623 to move closer to or away from the working disk 12, thereby making the push bar 6231 move closer to or away from the working disk 12.

[0067] A push chute 6213 is formed on the side of the storage base plate 621 away from the pusher trough 6212. Several pusher chutes 6213 are connected to form a long slot for the bearing to move. The length of this slot aligns with the length of the pusher base plate. When the piston rod of the cylinder retracts into the cylinder body, the end of the pusher bar 6231 closest to the work plate 12 moves within the pusher trough 6212 toward the storage trough 6211, pushing the bearing located in the pusher hole 6221 of the storage chamber 622 out of the storage chamber 622 and ultimately into the pusher chute 6213.

[0068] An extension plate 626 is integrally formed on the side of the storage base plate 621 close to the bearing loading robot 61. The extension plate 626 is provided with an extension groove 6261 which is consistent with the axial direction of the pushing chute 6213 and communicates with the pushing chute 6213. At this time, the end of the extension groove 6261 away from the pushing chute 6213 is the outlet end of the bearing storage assembly 62.

[0069] Reference Figure 4 and Figure 5 A pusher block 624 is slidably disposed within the pusher chute 6213 and the extension slot 6261. This pusher block 624 is connected to a drive structure that drives the pusher block 624 to slide back and forth along the pusher chute 6213 and the extension slot 6261. In this embodiment, the drive structure comprises a motor screw. The pusher block 624 pushes the bearing pushed by the pusher strip 6231 into the pusher chute 6213 into the extension slot 6261. The bearing loading robot 61 removes the bearing from the outlet of the extension slot 6261 and places it in the assembly cavity 14. Each time the bearing loading robot 61 removes a bearing, the pusher block 624 pushes the remaining bearings forward one bearing position, ensuring that there is always a bearing at the outlet of the extension plate 626 for the bearing loading robot 61 to remove.

[0070] A pressure plate 627 is installed on the top wall of the storage base plate 621 by bolts. The pressure plate 627 is located directly above a number of pushing chutes 6213. The length direction of the pressure plate 627 is consistent with the length direction of the storage base plate 621. The pressure plate 627 is provided with a pressure waist hole 6271 along the length direction. The pressure waist hole 6271 passes through the pressure plate 627 in the vertical direction. The pushing block 624 passes through the pressure hole and moves back and forth in the pressure waist hole 6271; the width direction of the pressure waist hole 6271 is smaller than the diameter of the bearing.

[0071] The bearing loading robot 61 places the bearing at the outlet of the extension plate 626 into the assembly cavity 14 of the bearing loading area 2. As the assembly cavity 14 with the bearing rotates under the work plate 12 and passes inspection by the inspection element 16, it moves to the housing loading area 3. The operator then places the housing in the assembly cavity 14 and clamps the wires connected to the housing between the fixed vertical plate 152 and the clamping vertical plate 153 through the first clearance notch 141 and the second clearance notch 1521.

[0072] After the housing is placed in the housing loading area 3, the work plate 12 rotates to the first pressing mechanism 17 for a press fit test. After passing the press fit test, it is moved to the semi-assembly loading area 4. In the semi-assembly loading area 4, the semi-assembly undergoes torque testing and is manually placed on the housing. The work plate 12 rotates to the second pressing mechanism 18 for a press fit test. After passing the press fit test, it is moved to the unloading area 5.

[0073] Reference Figure 2 and Figure 7 Qualified brakes tested in the unloading area 5 are unloaded from the assembly machine by the unloading mechanism 7. The unloading mechanism 7 includes an unloading robot 71 and an unloading transport assembly 72. The unloading robot 71 is mounted on the top platform 112. In this embodiment, the unloading robot 71 is composed of multiple cylinders and pneumatic grippers. In other embodiments, the unloading robot 71 can also be implemented by other structures known to those skilled in the art.

[0074] The unloading and transporting assembly 72 is installed on the base 111 , with its inlet end close to the unloading area 5 and its outlet end outside the machine body 1 ; the unloading robot 71 reciprocates between the unloading area 5 and the inlet section of the unloading and transporting assembly 72 .

[0075] Reference Figure 7 The unloading transport component 72 includes a unloading conveyor belt 721 and several transport blocks 722. The unloading conveyor belt 721 is driven to rotate by a motor and a belt. The inlet end of the unloading conveyor belt 721 is close to the unloading area 5, and the outlet end is located outside the machine body 1; several transport blocks 722 are clamped on the belt, and several transport blocks 722 are evenly arranged along the length direction of the belt.

[0076] A notch for extending the power supply line is preset on the side wall of the transport block 722 facing away from the working disk 12, and a lead plate 723 is extended on the side of the unloading conveyor belt 721 facing away from the working disk 12. A limiting plate 724 is vertically integrated with the lead plate 723 on the side away from the unloading conveyor belt 721, and the length direction of the lead plate 723 and the length direction of the limiting plate 724 are both consistent with the transport direction of the conveyor belt.

[0077] The unloading robot 71 removes the brake at the unloading area 5 from the assembly cavity 14 and places it on the corresponding transport block 722. The lead wire comes out from the notch of the transport block 722 and is placed on the lead plate 723. During the movement of the unloading conveyor belt 721, the lead wire moves along the lead plate 723.

[0078] After the brake in the assembly cavity 14 in the unloading area 5 is removed, the work disc 12 rotates to the detection position 19 for detection to determine whether there are any brake parts left in the assembly cavity 14. If there are no brake parts left, it means that the unloading is clean, and the work disc 12 drives the assembly cavity 14 to move to the bearing loading area 2 for bearing loading to carry out a new round of assembly operations.

[0079] The operating principle of a brake assembly machine according to an embodiment of the present application is as follows: When the brake assembly machine begins operation, the bearing loading mechanism 6 places the bearing on the assembly station in the bearing loading area 2. For convenience, the assembly station where the bearing is placed is referred to as the processing station. The work disk 12 rotates circumferentially. When the processing station moves to the next station, it is inspected by a detection component 16 to determine whether the bearing is properly placed within the processing station. If the inspection passes, it moves to the next station, the housing loading area 3. The housing with the electrical wiring is placed in the processing station in the housing loading area 3 and fitted onto the outside of the bearing. The work disk 12 continues to move, and when the processing station moves to the next station, the pressing mechanism 17 presses the housing and bearing together, and the inspection component is used to check whether the assembly passes. If the inspection passes, the processing station moves to the next station, the semi-assembly loading area 4. The semi-assembly, consisting of a flange and a spline shaft, is placed on top of the housing. The spline shaft is then inserted into the bearing. As the worktable 12 continues to move, moving the processing station to the next station, the second pressing mechanism 18 assembles the semi-assembly, housing, and bearing, and uses a test piece to verify that the assembly is qualified. If qualified, the processing station moves to the next station, the unloading area 5, where the unloading mechanism 7 unloads the qualified brake. As the worktable 12 continues to move, moving the processing station to the next station, the second test piece 19 verifies that the assembled brake in the processing station has been unloaded cleanly. If qualified, the processing station can move again to the bearing loading area 2, completing the above cycle.

[0080] The various parts required for the brake are assembled in sequence on the assembly machine. At the same time, the assembly gaps of each part are used to achieve pressing or testing when assembling other brakes, so that multiple brakes can be assembled at the same time, thereby improving the assembly efficiency of the brake.

[0081] The present application also discloses a brake assembly process using a brake assembly machine, comprising the following steps:

[0082] S1. Under the action of gravity, the bearings stored in the storage cavity 622 fall to the storage hole. Under the action of the cylinder, the pushing bar 6231 moves in the pushing groove 6212 toward one end of the working disk 12. The pushing bar 6231 pushes the bearing located in the pushing hole 6221 in the storage cavity 622 out of the storage cavity 622 and finally pushes it into the pushing chute 6213.

[0083] At this time, several pushed-out bearings are scattered in each pushing chute 6213, and the pushing block 624 pushes the bearings pushed to the pushing chute 6213 by the pushing strip 6231 into the extension groove 6261. The bearing loading robot 61 takes the bearings at the outlet end of the extension groove 6261 and places them in the assembly cavity 14.

[0084] Each time the bearing loading robot 61 removes a bearing, the pusher block 624 pushes the remaining bearings forward one bearing position, ensuring that there is always a bearing at the outlet end of the extension plate 626 for the bearing loading robot 61 to remove. The bearing loading robot 61 places the bearing at the outlet end of the extension plate 626 into the assembly cavity 14 of the bearing loading area 2.

[0085] S2, the work plate 12 rotates and rotates the assembly station with the bearing to the detection part 16 for detection to determine whether the bearing is placed in place. After the bearing position detection is qualified, the work plate 12 continues to rotate.

[0086] S3. When the assembly station with the bearing moves to the housing loading area 3, the housing with the wires is placed on the assembly station and sleeved on the outside of the bearing.

[0087] S4, the working disk 12 continues to rotate to the next station, the bearing with the housing is pressed by the pressing mechanism 17, so that the housing and the bearing are assembled, and the assembled housing and bearing are inspected by the detection part to determine whether the housing and the bearing are installed in place. After the housing and the bearing are inspected and installed, the working disk 12 continues to rotate.

[0088] S5. When the assembly station with the housing and bearing moves to the semi-assembly loading area 4, the semi-assembly with the flange and spline shaft is placed on the housing, one end of the spline shaft is inserted into the bearing, and the working disk 12 continues to rotate.

[0089] S6. The working disc 12 continues to rotate to the next station. The semi-assembled parts with flanges and spline shafts are pressed onto the housing and bearings by the pressing mechanism 2 18 to complete the assembly of the brake. The inspection part inspects the assembled brake to determine whether the assembly is stable. The qualified brake is moved to the unloading area 5 by the rotating working disc 12.

[0090] S7. The unloading robot 71 removes the brake at the unloading area 5 from the assembly cavity 14 and places it on the corresponding transport block 722. The lead wire comes out from the notch of the transport block 722 and is placed on the lead plate 723. During the movement of the unloading conveyor belt 721, the lead wire moves along the lead plate 723.

[0091] S8. After the brake in the assembly cavity 14 in the unloading area 5 is removed, the work disk 12 rotates to the detection point 19 for detection to determine whether there are any brake parts left in the assembly cavity 14. If there are no brake parts left, it means that the unloading is clean, and the work disk 12 drives the assembly cavity 14 to move to the bearing loading area 2 for bearing loading to carry out a new round of assembly operations.

[0092] Another implementation:

[0093] This application also provides another embodiment, which is different from the above embodiment in that, referring to Figure 8 and Figure 9 The workbench 11 is located in the shell loading area 3 and is provided with a shell loading mechanism 8. The shell loading mechanism 8 includes a shell storage component 84. The shell storage component 84 is installed on the base 111. The outlet end of the shell storage component 84 is close to the working disk 12.

[0094] The shell material storage assembly 84 includes a shell material storage cavity 841, which is fixed and tilted on the base 111 by bolts. The shell material storage cavity 841 is tilted downward toward the working disk 12, and the height of the shell material storage cavity 841 close to one end of the working disk 12 is consistent with the height of the assembly cavity 14.

[0095] A guide cavity 842 is integrally formed on one side of the width direction of the shell storage cavity 841, and the inclination direction of the guide cavity 842 is consistent with the inclination direction of the shell storage cavity 841. Both ends of the shell storage cavity 841 and the guide cavity 842 are provided with a gap.

[0096] A guide long hole 8411 is provided on the side wall where the shell storage cavity 841 contacts the guide cavity 842 in an inclined direction; the guide long hole 8411 connects the interior of the shell storage cavity 841 and the interior of the guide cavity 842. When the shell is placed in the shell storage cavity 841, the wires of the shell are removed through the guide long hole 8411 and placed in the guide cavity 842.

[0097] A shell loading robot 81 is also installed on the top platform 112. In this embodiment, the shell loading robot 81 is composed of multiple cylinders and pneumatic clamps. In other embodiments, the shell loading robot 81 can also be implemented by other structures known to people in this field.

[0098] A straightening rod 83 is slidably installed on the cylinder body of the pneumatic clamp of the shell loading robot 81, and the straightening rod 83 moves back and forth along the width direction of the shell storage cavity 841. A lower pressure plate 82 is fixedly installed on the cylinder body of the pneumatic clamp of the shell loading robot 81, and the lower pressure plate 82 is located above the straightening rod 83. The end of the lower pressure plate 82 away from the pneumatic clamp is located directly above the area formed between the clamping vertical plate 153 and the fixed vertical plate 152.

[0099] The shell loading robot 81 takes the shell from the notch of the shell storage cavity 841 . At this time, the wires of the shell sag under the action of gravity and stick to the side wall of the lower pressing plate 82 .

[0100] During the movement of the shell loading robot 81 toward the assembly cavity 14, the straightening rod 83 moves along the width direction of the shell storage cavity 841. At this time, the shell wires change from a drooping state to an approximately parallel state of the wound part of the wires under the movement of the straightening rod 83. At this time, the shell wires are in contact with the bottom wall of the lower pressure plate 82. At the same time, the shell robot has moved the shell to directly above the assembly cavity 14 in the shell loading area 3.

[0101] The shell loading robot 81 moves downward to place the shell in the assembly cavity 14, and the lower pressure plate 82 presses the wires between the fixed vertical plate 152 and the clamping vertical plate 153. At this time, one end of the lower pressure plate 82 is inserted between the holding vertical plate and the fixed vertical plate 152; at the same time, the straightening rod 83 has moved from one side of the fixed vertical plate 152 to the other side, that is, when the shell loading robot 81 descends, the straightening rod 83 and the fixed vertical plate 152 cannot collide.

[0102] The difference between this embodiment and other embodiments is that the shell is also loaded automatically, and the position fixation of the wires during the shell assembly process is solved during the loading process, which further improves the assembly efficiency of the brake and reduces labor.

[0103] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
