Description

Technical Field

[0001] This utility model relates to the field of vehicle parts manufacturing equipment, specifically to a pressing device for the housing and bracket of a body controller host. Background Technology

[0002] The body control unit (ECU) is an important component of a car, used to control the vehicle's electrical systems. (See also...) Figure 1 The body controller host is mounted on the vehicle frame via bracket 200. The outer shell 100 of the body controller host has multiple clips 300 on its surface. During assembly, the bracket is pressed onto the outer shell, and the outer shell holds the bracket in place by the clips. The bracket has two mounting holes 400, which are used to fix the bracket to the vehicle frame. The position of these two mounting holes affects the installation accuracy of the bracket, so the position of these two mounting holes needs to be checked.

[0003] The existing pressing equipment does not have the function of detecting the position of the two mounting holes on the bracket. The assembly personnel first press the bracket and the shell together, and then place the product on the bracket hole gauge to detect the hole position. The operation is cumbersome and wastes time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressing device for the housing and bracket of a vehicle body controller host, integrating bracket hole detection and pressing functions into one unit to improve production efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: This utility model provides a pressing device for the housing and bracket of a vehicle body controller host, including a frame assembly, a drive component mounted on the frame assembly, and a pressing module. The pressing module includes a fixed plate and a movable plate, with the movable plate located above the fixed plate. A wedge block and a pressing component are mounted on the bottom surface of the movable plate. A slider assembly, a positioning fixture, and two hole detection components are mounted on the fixed plate. The slider assembly is located between the two hole detection components, and the positioning fixture is located at one end of the slider assembly. The drive component drives the movable plate to move the wedge block and the pressing component up and down. The wedge block and the slider assembly cooperate to push the bracket from the hole detection components to above the positioning fixture. The pressing component is used to press the bracket against the housing placed in the positioning fixture.

[0006] Preferably, the hole detection assembly includes a support block, a movable column, a cylindrical head screw, and a first spring. The support block has a vertical receiving hole, in which the movable column for hole detection is located. The hole detection portion at the top of the movable column protrudes from the top surface of the support block. The bottom surface of the movable column and the fixing plate have corresponding spring mounting holes for accommodating the first spring. The cylindrical head screw is fixed to the movable column.

[0007] Preferably, the slider assembly includes a slider, a slide rail, a second spring, and a follower block. The slide rail is located between the two hole detection assemblies. The slider is slidably mounted on the slide rail. The follower block is mounted on the slider. The positioning fixture is located at one end of the slide rail along its length. The follower block is located below the wedge block. The wedge block is used to drive the follower block to move toward the positioning fixture. The second spring abuts against the side of the follower block near the positioning fixture to drive the follower block to reset.

[0008] Preferably, the slider assembly further includes a fixed shaft, and the fixed plate is provided with two mounting seats. The two ends of the fixed shaft are respectively fixed on the two mounting seats. The second spring is sleeved on the fixed shaft and is parallel to the slide rail. The two ends of the second spring abut against the follower block and the mounting seat near the positioning fixture, respectively. A cylindrical head screw is installed on the follower block, and the wedge block drives the follower block by pushing the cylindrical head screw.

[0009] Preferably, each side of the follower block protrudes to form a boss. The boss has a first inclined surface and a second inclined surface along the sliding rail moving direction. When the follower block moves along the sliding rail to approach the positioning fixture, the first inclined surface presses down on the cylindrical head screw on the movable column so that the hole detection part at the top of the movable column retracts into the bearing block. When the follower block is reset, the second inclined surface presses down on the cylindrical head screw on the movable column to avoid the cylindrical head screw from obstructing the movement of the follower block.

[0010] Preferably, the pressing assembly includes a base, a third spring, a pressure rod, a rolling element, and a screw. The base is fixedly connected to a movable plate. The base has several vertical through holes. Each vertical through hole contains a fixed rod, a third spring, and a pressure rod. The upper end of the fixed rod is fixed to the movable plate. The third spring is sleeved on the fixed rod. The upper end of the pressure rod is inserted into the vertical through hole. The lower end of the pressure rod is equipped with a rolling element. One end of the third spring abuts against the movable plate, and the other end abuts against the pressure rod. The side of the pressure rod has a vertical limiting groove. The screw is fixed to the base and inserted into the limiting groove on the pressure rod.

[0011] Preferably, the frame assembly includes a base plate, a top plate, and two columns. The two columns connect the base plate and the top plate, and the top plate and the base plate are parallel. The drive component includes a cylinder and a push rod that is telescopic relative to the cylinder. The cylinder is mounted on the top plate, and the push rod is connected to a movable plate. A first sleeve is installed at each end of the movable plate, and the two first sleeves are slidably fitted onto the two columns respectively.

[0012] This utility model has the following beneficial effects: The pressing device provided by this utility model uses a wedge block and a slider assembly to move the bracket from the hole detection position to the pressing position. Only one driving component is used to realize the two actions of moving and pressing the bracket. The structure is compact and integrates the two processes of hole detection and pressing, which improves efficiency and reduces working time. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] like Figures 1 to 8 As shown, this embodiment discloses a pressing device for the housing 100 and bracket 200 of a vehicle body controller host, including a frame assembly 1, a drive component 2 mounted on the frame assembly 1, and a pressing module 3.

[0016] The frame assembly 1 includes a base plate 11, a top plate 12, and two uprights 13. The two uprights 13 connect the base plate 11 and the top plate 12, and the top plate 12 and the base plate 11 are parallel. The drive component 2 includes a cylinder and a push rod that is retractable relative to the cylinder. The cylinder is mounted on the top plate 12, and the push rod is connected to a movable plate 14. Specifically, the drive component 2 is a pneumatic cylinder or a hydraulic cylinder. A first sleeve 15 is installed at each end of the movable plate 14, and the two first sleeves 15 are slidably fitted onto the two uprights 13 respectively (the number of uprights 13 and sleeves can be increased). The pneumatic cylinder drives the movable plate 14 to move up and down between the top plate 12 and the base plate 11. In other embodiments, the number of first sleeves 15 and uprights 13 is not limited to that described in this embodiment and can be selected according to the size of the movable plate 14.

[0017] The pressing module 3 includes a fixed plate 31 and a movable plate 32. The movable plate 32 is located above the fixed plate 31 and is fixed to the bottom surface of the movable plate 14. A second sleeve 33 is installed on the movable plate 32, and a guide post 33 is installed on the fixed plate 31. The second sleeve 33 is fitted onto the guide post 33. A limit post 34 is installed on the fixed plate 31. There is a certain distance between the top surface of the limit post 34 and the movable plate 32 to prevent the movable plate 32 from moving too far downward during misoperation, which could cause interference and damage to the parts between the movable plate 32 and the fixed plate 31.

[0018] like Figure 4 The bottom surface of the movable plate 32 is equipped with a wedge block 35 and a pressing component 36. The fixed plate 31 is equipped with a slider assembly 311, a positioning fixture 312 and two hole detection components 313. The slider assembly 311 is located between the two hole detection components 313, and the positioning fixture 312 is located at one end of the slider assembly 311.

[0019] like Figure 8 The slider assembly 311 includes a slider 3111, a slide rail 3112, a fixed shaft 3113, a second spring 3114, and a follower block 3115. The slide rail 3112 is located between two hole detection assemblies 313. The slider 3111 is slidably mounted on the slide rail 3112. The follower block 3115 is mounted on the slider 3111. The fixed plate 31 is provided with two mounting seats 3116. The two ends of the fixed shaft 3113 are respectively fixed on the two mounting seats 3116. The second spring 3114 is sleeved on the fixed shaft 3113. The axial direction of the second spring 3114 is consistent with the length direction of the slide rail 3112 (the second spring 3114 is parallel to the slide rail 3112). The follower block 3115 is sleeved on the fixed shaft 3113. The positioning fixture 312 is located at one end of the length direction of the slide rail 3112. The two ends of the second spring 3114 abut against the follower block 3115 and the mounting seat 3116 near the positioning fixture 312, respectively.

[0020] Preferably, a cylindrical head screw 4 (preferably a cylindrical head hexagonal screw) is installed on the follower block 3115. The cylindrical head screw 4 is located below the wedge block 35, and the wedge block 35 cooperates with the cylindrical head screw 4. The driving component 2 drives the wedge block 35 to move downward. The wedge block 35 pushes the cylindrical head screw 4 to realize the horizontal movement of the follower block 3115 along the slide rail 3112. The cylindrical head screw 4 on the follower block 3115 is not necessary. The cylindrical part of the cylindrical head screw 4 has low friction with the wedge block 35, and the wedge block 35 does not directly contact the follower block 3115, avoiding wear of the follower block 3115 and frequent maintenance.

[0021] Each hole detection assembly 313 includes a support block 3131, a movable column 3132, a cylindrical head screw 4, and a first spring 3133. The support block 3131 has a vertical receiving hole, in which the movable column 3132 for hole detection is located. The hole detection portion at the top of the movable column 3132 protrudes from the top surface of the support block 3131. The first spring 3133 is located below the movable column 3132 (the bottom surface of the movable column 3132 and the fixing plate 31 have corresponding spring mounting holes for accommodating the first spring 3133). The cylindrical head screw 4 is fixed to the movable column 3132. The support block 3131 has a clearance groove to allow for the vertical movement of the cylindrical head screw 4.

[0022] The bracket 200 of the body controller is placed on the support block 3131 of the two hole detection components 313. It is observed whether the hole detection parts at the top of the two movable columns 3132 can be accurately inserted into the two holes to be tested on the bracket 200, thereby determining whether the two holes to be tested meet the requirements. After being tested by the two hole detection components 313, the bracket 200 with qualified hole positions is pushed by the slider assembly 311 onto the positioning fixture 312, and pressed against the housing 100 of the body controller that is pre-placed in the positioning fixture 312. The pressing action is performed by the pressing component 36.

[0023] Under normal conditions, after the bracket 200 is placed on the support block 3131, the hole detection part protrudes from the top of the support block 3131 and inserts into the detection hole on the bracket 200. At this time, the bracket 200 cannot be pushed by the follower block 3115. The follower block 3115 has a boss 31151 protruding from each side. Figure 8 The boss 31151 is provided with a first inclined surface 31152 and a second inclined surface 31153 along the moving direction of the slide rail 3112. When the wedge block 35 moves down to drive the follower block 3115 to move along the slide rail 3112 to approach the positioning fixture 312, the first inclined surface 31152 presses down on the cylindrical head screw 4 on the movable column 3132 (at this time the first spring 3133 is compressed) so that the hole detection part at the top of the movable column 3132 retracts into the bearing block 3131. After that, when the follower block 3115 moves, it can push the bracket 200.

[0024] When the wedge block 35 moves upward, the second spring 3114 rebounds and drives the follower block 3115 to move away from the positioning fixture 312. During this process, the second inclined surface 31153 presses down on the cylindrical head screw 4 on the movable column 3132, thereby preventing the cylindrical head screw 4 from obstructing the follower block 3115 from resetting.

[0025] like Figure 6The pressing assembly 36 includes a base 361, a third spring 362, a pressure rod 363, a rolling element 364, and a screw 365. The base 361 is fixedly connected to the movable plate 32. The base 361 has several vertical through holes. Each vertical through hole contains a fixed rod 366, a third spring 362, and a pressure rod 363. The upper end of the fixed rod 366 is fixed to the movable plate 32. The third spring 362 is sleeved on the fixed rod 366. The upper end of the pressure rod 363 is inserted into the vertical through hole. The rolling element 364 is installed at the lower end of the pressure rod 363. One end of the third spring 362 abuts against the movable plate 32, and the other end abuts against the pressure rod 363. The rolling element 364 is preferably a bearing, but a roller can also be used instead.

[0026] The base 361 has screw mounting holes, and the pressure rod 363 has a vertical limiting groove 367 on its side. The screw 365 is fixed in the screw mounting holes of the base 361 and inserted into the limiting groove 367 on the pressure rod 363. The screw 365 and the limiting groove 367 cooperate to prevent the pressure rod 363 from detaching downward from the base 361, and the pressure rod 363 can extend and retract relative to the base 361. When the follower block 3115 moves toward the positioning fixture 312, it pushes the bracket 200 directly below the pressing component 36. The pressing component 36 moves down, and the rolling element 364 presses onto the bracket 200. The seat 361 continues to move down. When the screw 365 reaches the lowest point of the limiting groove 367, the seat 361 continues to move down. The screw 365 will press down the pressure rod 363, thereby pressing down the bracket 200 with the rolling element 364. The housing 100 has a buckle at the position for mounting the bracket 200. The bracket 200 is locked by the buckle, thus completing the pressing of the bracket 200 and the housing 100.
