Description

Technical Field

[0001] This utility model relates to an engine balance box assembly device, belonging to the field of automotive parts assembly technology. Background Technology

[0002] An engine balance box can neutralize the vibrations generated when the engine is running, thereby enhancing the engine's stability and durability. It can effectively reduce the vibration of the entire vehicle, making the engine run more smoothly, thereby reducing noise during driving and improving passenger comfort. It is an important component of automobiles.

[0003] An engine balance box typically consists of two upper and lower housings and two balance shafts housed within them. The upper and lower housings are fastened together by multiple bolts. Currently, engine balance boxes are usually assembled manually. Workers engage the two balance shafts and place them into the lower housing, then assemble the upper and lower housings and tighten the bolts. However, manual placement and removal are inefficient, and the tightening and assembly operations are time-consuming and labor-intensive, resulting in low overall production efficiency for engine balance boxes.

[0004] Therefore, how to provide an engine balance box assembly equipment with high production efficiency is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1 and Figure 2An engine balance box assembly device includes a frame 1 and a chain conveyor 2. The chain conveyor 2 is mounted on the frame 1. A working fixture 3 is slidably mounted on the frame 1 via the chain conveyor 2. The working fixture 3 is used for assembling various components of the engine balance box and serves as an assembly platform. A balance shaft gripping mechanism 4, a phase detection mechanism 5, a marking mechanism 14, a bolt feeding mechanism 6, and a tightening assembly mechanism 7 are sequentially installed on the frame 1 along the conveying direction of the chain conveyor 2, realizing the entire assembly process of placing the balance shaft of the engine balance box into the box body. A balance shaft placement fixture 8 is installed on the side of the frame 1 opposite to the phase detection mechanism 5, so that the operator can position and place the balance shaft required for assembly. Then, the automatic assembly operation is realized through the various mechanisms in the equipment. The entire operation process only requires the operator to place the balance shaft and the engine balance box, as well as assemble the upper and lower boxes of the engine balance box, reducing manual labor and thus improving production efficiency.

[0027] Furthermore, the balance shaft placement fixture 8 includes a lifting bracket 81, a placement plate 82, and a placement seat 83. The lifting bracket 81 is fixedly installed on the frame 1 by bolts and at least one is installed thereon. The placement plate 82 is inserted and installed on the lifting bracket 81, so that it can be supported by the lifting bracket 81 and its height can be adjusted. The placement plate 82 is evenly distributed with a number of positioning holes 821. The placement seat 83 is provided with a number of corresponding balance shafts in the engine balance box and is positioned and installed by screws that are compatible with the positioning holes 821, so that the balance shaft can be positioned and placed, which is convenient for the balance shaft gripping mechanism 4 to grip.

[0028] The working fixture 3 includes a working slide 31, positioning columns 32, and mounting base 33. The working slide 31 is mounted on a chain conveyor 2 and moves via the chain conveyor 2. Multiple positioning columns 32 are provided and are detachably mounted on the working slide 31 with bolts to provide stable support for the lower housing of the engine balance box. The height of the multiple positioning columns 32 is adapted to the height of the corresponding position of the lower housing of the engine balance box. The mounting base 33 is detachably mounted on the working slide 31 with bolts. The mounting base 33 has a groove that fits into the upper housing of the engine balance box to position and place the upper housing of the engine balance box. In actual application, the positioning columns 32 and mounting base 33 can be installed or replaced according to the actual size of the engine balance box.

[0029] Reference Figure 1The balance shaft gripping mechanism 4, the phase detection mechanism 5, and the bolt feeding mechanism 6 all have a three-axis linkage mechanism 9. The three-axis linkage mechanism 9 includes a vertical moving mechanism, a horizontal moving mechanism, and a longitudinal moving mechanism, capable of moving vertically, horizontally, and longitudinally. The longitudinal moving mechanism is mounted on the frame 1, and its guide slider, driven by a linear motor, cooperates with the guide rail to achieve the forward and backward movement of the functional components on each mechanism. The linear motor of the longitudinal moving mechanism is mounted above the chain conveyor 2 via the frame 1. The horizontal moving mechanism is mounted on the guide slider of the vertical moving mechanism, and its guide slider, driven by a linear motor, cooperates with the guide rail. The system enables the left and right movement of functional components on each mechanism. The linear motor of the lateral movement mechanism is mounted on the guide slider of the longitudinal movement mechanism; the vertical movement mechanism is mounted on the guide slider of the lateral movement mechanism. The top drive cylinder drives the functional components on each mechanism to achieve lifting operations through the connecting block and the lifting slider. The drive cylinder is mounted on the guide slider of the lateral movement mechanism. In this embodiment, the use of linear motors and drive cylinders are existing technologies and will not be described in detail. At the same time, any assembly order of the vertical movement mechanism, lateral movement mechanism and longitudinal movement mechanism is also within the protection scope of this application. It is only necessary to achieve three-axis linkage.

[0030] Furthermore, the functional components of the balance shaft gripping mechanism 4 include multiple pneumatic grippers 41 fixedly mounted on the lifting slider of the vertical moving mechanism by bolts. The number of pneumatic grippers 41 corresponds to the number of balance shafts and is used to grip the balance shaft to be assembled and place it into the engine balance box. The functional components of the bolt feeding mechanism 6 include at least one pneumatic gripper 61 mounted on the lifting slider of the vertical moving mechanism and is used to grip the bolts for assembling the engine balance box and place them into the bolt assembly points on the engine balance box. In this embodiment, the installation and control of the pneumatic grippers are existing technologies and will not be described in detail.

[0031] Furthermore, the phase detection mechanism 5 also includes a shaft runout test bar 51 and a phase detection sensor 52. The shaft runout test bar 51 is driven by the three-axis linkage mechanism 9 of the phase detection mechanism 5 to move in three axes to verify the radial runout, axial movement, coaxiality, parallelism, etc. of the balance shaft assembled in the engine balance box on the working fixture 3. The phase detection sensor 52 is set on both sides of the chain conveyor 2 perpendicular to the conveying direction of the chain conveyor 2 to perform phase detection on the balance shaft assembled in the engine balance box on the working fixture 3. In this embodiment, the detection of the shaft runout test bar 51 and the phase detection sensor 52 is the prior art and will not be described in detail.

[0032] Reference Figure 1In a further embodiment, the bolt feeding mechanism 6 also includes a bolt vibrating screen feeder 62. The bolt vibrating screen feeder 62 is installed on one side of the three-axis linkage mechanism 9 at the bolt feeding mechanism 6 so that the pneumatic gripper 61 can continuously grip the assembly bolts. The bolt vibrating screen feeder 62 can ensure the continuous automatic supply of bolts for assembling the engine balance box, which further reduces labor while ensuring processing efficiency. In this embodiment, the use of the bolt vibrating screen feeder 62 is prior art and will not be described in detail.

[0033] During assembly, after the balance shaft undergoes phase detection, the work fixture 3 is conveyed to the bolt feeding mechanism 6 via the chain conveyor 2. The operator removes the upper housing of the engine balance box from the mounting base 33 and assembles it with the lower housing of the engine balance box. Then, the chain conveyor 2 conveys the work fixture 3 again, and the engine balance box with the upper housing installed is sent to the marking mechanism 14 for marking. The specifications, model, and production date of the engine balance box can be clearly marked. Finally, it is sent to the bolt feeding mechanism 6 for the placement of bolts for engine balance box assembly. In this embodiment, the marking mechanism 14 of the chassis is existing technology and will not be described in detail.

[0034] Reference Figures 1-3 The tightening assembly mechanism 7 includes a lifting frame 71, a lifting seat 72, a power component 1 73, an assembly kit 74, a working shaft 75, and a power component 2 76. The lifting frame 71 is located on one side of the chain conveyor 2. The lifting seat 72 is driven to lift and lower on the lifting frame 71 by the power component 1 73. In feasible embodiments, the power component 1 73 includes, but is not limited to, a threaded rod driven by a cylinder or a motor. The assembly kit 74, the working shaft 75, and the power component 2 76 are set together and multiple sets are installed corresponding to the bolt assembly holes on the engine balance box. The working shaft 75 is driven to rotate on the lifting seat 72 by the power component 2 76. The power component 2 76 is a servo motor. The assembly kit 74 slides and is sleeved on the working shaft 75 along the axial direction of the working shaft 75 and can rotate coaxially with the working shaft 75. The assembly kit 74 has an assembly hole that is adapted to the bolt head of the bolt for assembling the engine balance box. In this embodiment, the power component 1 73 is preferably a threaded rod driven by a motor.

[0035] Furthermore, multiple limiting blocks 751 are circumferentially distributed on the outer wall of the working shaft 75. The limiting blocks 751 are integrally formed with the working shaft 75. The inner wall of the assembly 74 is provided with a limiting groove 741 that slides and cooperates with the limiting blocks 751, which can guide the sliding of the assembly 74. At the same time, when the working shaft 75 is rotating, the limiting blocks 751 can drive the assembly 74 to rotate synchronously.

[0036] Once all the bolts for assembling the engine balance box are in place, the chain conveyor 2 starts to transport the workpiece 3 to the tightening assembly mechanism 7. The lifting frame 71 descends, causing the assembly piece 74 and the working shaft 75 to descend until the assembly piece 74 is inserted into the bolt. The sliding cooperation between the assembly piece 74 and the working shaft 75 ensures that the insertion of the assembly piece 74 into the bolt has a certain self-adjusting capability. Subsequently, the lifting frame 71 continues to drive the assembly piece 74 and the working shaft 75 to descend, so that the assembly piece 74 is stably inserted into the bolt. Then, the power component 2 76 drives the synchronous rotation of the working shaft 75 and the assembly piece 74 to complete the assembly and tightening operation of the bolts on the engine balance box.

[0037] Reference Figure 1 An engine balance box assembly device further includes a limiting component 10 and a support component 11. The limiting component 10 and the support component 11 are both installed on the frame 1 and are arranged in multiple sets corresponding to the balance shaft gripping mechanism 4, the phase detection mechanism 5, the marking mechanism 14, the bolt feeding mechanism 6 and the tightening assembly mechanism 7. The limiting component 10 is used to limit and stop the working tool 3 when it reaches the position of the corresponding assembly mechanism. The support component 11 is used to fix the working tool 3 during the assembly operation so that the working tool 3 can be separated from the chain conveyor 2.

[0038] The limiting component 10 includes a positioning block 101, a limiting stop 102, and a driving component 103. The positioning block 101 is mounted on the chain conveyor 2. The limiting stop 102 is driven to rise and fall on the positioning block 101 by the driving component 103, so as to limit the sliding of the working tool 3 on the chain conveyor 2 and ensure that the working tool 3 accurately reaches the working position of each mechanism of the engine balance box assembly equipment. In this embodiment, the driving component 103 is preferably a miniature electric cylinder, which is existing technology and will not be described in detail.

[0039] The support assembly 11 includes a fixed block 111, a top support block 112, and a lifting power component 113. The fixed block 111 is installed on the chain conveyor 2 on the side of the positioning block 101 facing the starting end of the working fixture 3. The top support block 112 is driven to lift and be positioned on the fixed block 111 by the lifting power component 113. The lifting power component 113 is a drive electric cylinder. When the working fixture 3 is intercepted into place by the limit assembly 10, the top support block 112 lifts the working fixture 3 and removes it from the chain conveyor 2. This reduces the possibility of the working fixture 3 and the engine balance box components shaking as they are conveyed by the chain conveyor 2, thereby improving assembly efficiency and assembly quality.

[0040] Reference Figure 1The frame 1 is equipped with a barcode scanner 12 on the side wall at the starting end of the chain conveyor 2. Each engine balance box and balance shaft has an independent product code, which facilitates the traceability of the assembly process and quality of each engine balance box by the operators. The use of barcode scanner 12 is existing technology and will not be described in detail.

[0041] Reference Figure 1 An engine balance box assembly device also includes a control unit 13, including but not limited to a PC and a PLC controller. In this embodiment, the control unit 13 is preferably a PC and is pre-configured with a control system for a balance shaft gripping mechanism 4, a phase detection mechanism 5, a marking mechanism 14, a bolt feeding mechanism 6, and a tightening assembly mechanism 7, thereby ensuring the sequential operation of each mechanism. This is existing technology and will not be described in detail.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model in any form or substance. It should be noted that those skilled in the art can make various improvements and additions without departing from this utility model, and these improvements and additions should also be considered within the protection scope of this utility model.
