Description

Technical Field

[0001] This invention relates to the field of vehicle suspension manufacturing, specifically to a dedicated assembly machine for special bar stock and two rings. Background Technology

[0002] In the production process of automotive stabilizer bars, two rings need to be moved to the center of the flattened bar material at both ends, and the flattened areas at both ends of the bar material are used as references to rotate to a specific angle.

[0003] Traditional production processes often require workers to manually thread two rings onto the bar stock, move the two rings to the center of the bar stock, and finally rotate them to the correct angle using specialized equipment. This traditional process not only requires manual labor but also lacks precision. Therefore, there is an urgent need for equipment that can not only replace manual labor but also improve assembly accuracy to enhance the efficiency and quality of automotive stabilizer bar production. To this end, we propose a specialized assembly machine designed for special bar stock and two rings. Summary of the Invention

[0004] The purpose of this invention is to provide a dedicated assembly machine for special bar stock and two rings.

[0005] The technical problem solved by this invention is: How to achieve automated assembly of rings and special bars and improve assembly accuracy.

[0006] This invention can be achieved through the following technical solution: a special assembly machine for special bar stock and two rings, including a conveyor belt transport module, a guide rail positioning module, a ring positioning module, a caliper positioning module, and a feeding conveyor belt transport module. The assembly component is transported to a predetermined position through the conveyor belt transport module. The guide rail positioning module is set on one side of the conveying end of the conveyor belt transport module and is used to perform multi-level positioning and transition of the assembly component. The ring positioning module is mounted above the guide rail positioning module and is used to assemble the ring fitted on the bar stock in the assembly component to the predetermined middle position of the bar stock. The feeding conveyor belt transport module is located at the transmission end of the guide rail positioning module, and the caliper positioning module is set on the side of the feeding conveyor belt transport module for clamping and rotating the end of the bar stock. The feeding conveyor belt transport module is used to receive the assembled parts and carry them out for subsequent transport.

[0007] A further technical improvement of the present invention is that the conveyor belt transport module includes two sets of parallel transmission components. Each set of transmission components includes a driving wheel and a driven wheel and a belt. The transmission components are driven by a motor. A stop block is provided above the belt near the driven wheel for limiting the assembly components. A positioning mechanism is symmetrically provided on the mounting bracket of the driven wheel. The positioning mechanism includes a retractable abutment block for adjusting the axial position of the bar on the belt.

[0008] A further technical improvement of the present invention is that: the guide rail positioning module includes a first-level guide rail, a second-level guide rail and a third-level guide rail arranged in sequence. Each level of guide rail includes two symmetrically arranged single guide rails. The first-level guide rail and the third-level guide rail are raised and lowered by a lifting seat. The second-level guide rail is fixed on the base. The guide rail surface of each level of guide rail is set as a downward slope, and the lower end of the guide rail is provided with an arc-shaped bayonet.

[0009] A further technical improvement of the present invention is that: the circular positioning module includes a bracket mounted on a base, two horizontal motion mechanisms are symmetrically arranged on the bracket, and each horizontal motion mechanism is provided with a vertical motion mechanism. A circular positioning device is fixed at the output end of the vertical motion mechanism, and the two circular positioning devices push the circular ring on the bar to the center position of the bar.

[0010] A further technical improvement of the present invention is that the circular positioning module also includes a vertical lifting mechanism fixed on the base, the vertical lifting mechanism including two symmetrically arranged positioning semi-rings that can be lifted and moved to support the bar stock.

[0011] A further technical improvement of the present invention is that: the caliper positioning module includes a caliper positioning module that can be driven to move horizontally, the caliper positioning mechanism includes a caliper that can be pneumatically tightened, and the line connecting the two calipers is set at a certain angle relative to the horizontal plane.

[0012] A further technical improvement of the present invention is that the feeding conveyor belt transportation module includes multiple sets of driving wheels and driven wheels. Each set of driving wheels is connected by a triangular conveyor belt to transport the assembled parts. The multiple sets of driving wheels are driven to rotate by a motor.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a guide rail positioning module to transport bar stock by the inclination of the guide rail, which greatly improves the transportation efficiency compared to the gripping of a robotic arm. At the same time, the positioning is achieved by opening a slot on the guide rail, eliminating the need for additional positioning elements and simplifying the structure of the equipment. This invention optimizes the ring positioning module, assembling the ring in the middle of the bar stock from both sides using ring positioners, thereby improving the efficiency and accuracy of ring positioning and assembly. This invention combines a guide rail positioning module and a caliper positioning module, simplifying the positioning of raw material angles. For bars with flat ends, it can rotate the bar to the same angle without changing the position of the assembly ring. Furthermore, compared to traditional manual production processes, this equipment adopts a fully automated production method: First, the automated equipment can operate 24 hours a day without being limited by human physiological conditions, greatly improving production efficiency. Second, by optimizing processing equipment and processes, assembly tasks can be performed with high precision and repeatability. Finally, the automated equipment can replace manual operation, reducing various accidents and greatly improving operator safety. Attached Figure Description

[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0018] Please see Figure 1As shown, the special assembly machine for special bar stock and two rings mainly consists of a conveyor belt transport module 1, a guide rail positioning module 2, a ring positioning module 3, a caliper positioning module 4, and a feeding conveyor belt transport module 5. The component to be assembled consists of a special bar stock with flat ends and two rings, and the rings need to be assembled into a predetermined position in the middle of the special bar stock during the assembly process.

[0019] First, place the pre-assembled components (circular rings pre-fitted onto the bar stock) onto the conveyor belt transport module 1; such as Figure 2 As shown, the transmission belt transport module 1 includes two sets of transmission components arranged in parallel. Each set of transmission components includes a drive wheel 102 rotatably mounted on a drive wheel mounting bracket and a driven wheel 104 rotatably mounted on a driven wheel mounting bracket. The drive wheel 102 and the driven wheel 104 are connected by a belt-like transmission belt 103. The drive wheel 102 is driven to rotate by a drive motor 101 fixedly mounted on the drive wheel mounting bracket. When the transmission components transport the special bar material and ring to be assembled to the side near the driven wheel 104, the stop block 106 fixed on the driven wheel mounting bracket limits its displacement and prevents it from continuing to move. At the same time, the positioning mechanism 105 fixed on the driven wheel mounting bracket in the two sets of transmission components abuts against the shaft end of the corresponding bar material through reciprocating feed motion to adjust its axial position on the belt-like transmission belt 103. Specifically, the positioning mechanism 105 includes an abutment block driven by a cylinder or an electric cylinder, and the output end of the power unit is fixedly connected to the abutment block.

[0020] like Figure 3 As shown, the guide rail positioning module 2 is a key component in the circular positioning assembly process, serving both transportation and positioning functions. The guide rail positioning module 2 is located near the transmission end of the belt conveyor 103 and includes three guide rail groups sequentially arranged on its base. Each guide rail group includes two symmetrically arranged single guide rails. The three guide rail groups are labeled as primary guide rail 201, secondary guide rail 202, and tertiary guide rail 203 from near to far from the belt conveyor module 1. The initial height of primary guide rail 201 is lower than that of secondary guide rail 202, and the initial height of secondary guide rail 202 is lower than that of tertiary guide rail 203. Specifically, the guide rail surface of each single guide rail is set as a downward sloping surface relative to the belt conveyor module 1 from near to far, and an arc-shaped locking end is provided at the lower position. Primary guide rail 201 and tertiary guide rail 203 are raised and lowered via lifting seats fixed on the base, while secondary guide rail 202 is directly fixed to the base.

[0021] The initial height of the primary guide rail 201 is lower than the height of the stop block 106. When the assembly component reaches the position of the stop block 106 along the belt drive 103, the lifting platform 106 drives the primary guide rail 201 to rise, lifting the assembly component so that it is separated from the belt drive 103, and rolls down the slope of the primary guide rail 201 to the slot opened on it for positioning. Then, the circular positioning module 3 set up above the primary guide rail 201 assembles the assembly component. After assembly is completed, the circular positioning module 3 releases the assembled component onto the secondary guide rail 202, and then rolls along the secondary guide rail 202 to its locking position. Subsequently, under the action of the lifting platform, the tertiary guide rail 203 is lifted, and the assembled component is supported on the tertiary guide rail 203 and rolls to the locking position of the tertiary guide rail 203. The feeding conveyor belt transport module 5 is located below the three-level guide rail 203. The caliper positioning module 4 is set on one side of the feeding conveyor belt transport module 5. When the assembly part enters the jaw of the three-level guide rail 203, the caliper positioning module 4 clamps and positions the end of the bar of the assembly part. Then the three-level guide rail 203 descends, and the assembled part falls onto the triangular conveyor belt 504 on the feeding conveyor belt transport module 5 and falls into the corresponding triangular groove for subsequent handling.

[0022] In the entire assembly and positioning process, the circular positioning module 3 is the core module, and it completes the main assembly tasks. For example... Figure 4 As shown, the circular positioning module 3 includes a vertical lifting mechanism 301 fixed on the base. The vertical lifting mechanism 301 includes two symmetrically arranged positioning half-rings that can be lifted and lowered by a cylinder or electric cylinder. When the assembly part enters the bayonet on the primary guide rail 201, the positioning half-rings rise to disengage the assembly part from the primary guide rail 201 and lift it to the assembly position. The primary guide rail 201 then descends to the initial height. The circular positioning module 3 also includes a bracket mounted on a base. Symmetrically arranged on the bracket are horizontally movable movement mechanisms 304, each with a vertical movement mechanism 305. A circular positioning device 306 is fixed to the output end of each vertical movement mechanism 305. The horizontal movement mechanisms 304 are driven by a transmission gear coaxially fixed to the end of a drive motor 302, which meshes with a rack horizontally fixed to the bracket. Thus, when the output end of the drive motor 302 rotates, the horizontal movement mechanism 304 moves through this meshing transmission. It should be noted that since the two circular rings need to be assembled in the middle of the bar stock, the two horizontal movement mechanisms 304 move away from or towards each other, and their movement speeds are synchronized. The vertical movement mechanism... The mechanism 305 uses a cylinder or electric cylinder to drive the ring positioner 306 to move vertically; an axial positioning mechanism 303 is also fixedly installed on the base outside the vertical lifting mechanism 301 to center and position the two ends of the assembly component mounted on the positioning half ring of the vertical lifting mechanism 301. Each axial positioning mechanism 303 has an extendable positioning block on the side near the end of the bar stock; thus, after the assembly component is lifted by the vertical lifting mechanism 301, the axial positioning mechanism 303 is activated to center and position it, and then the vertical movement mechanism 305 drives the ring positioner 306 to descend. After reaching the position, it drives the two horizontal movement mechanisms 304 to move closer to each other. During the movement of the two ring positioners 306, the rings slide relative to each other on the bar stock to the middle position of the bar stock to complete the assembly.

[0023] like Figure 5 As shown, the caliper positioning module 4 is the main body for completing the rotational positioning of the assembled parts. This module is installed on an independent base, and the assembled parts are re-supported on the three-stage guide rail 203. The caliper positioning module 4 has a horizontal moving mechanism 401 that can move along the axial direction of the bar stock. Specifically, the horizontal moving mechanism 401 is a support seat that can slide relative to the independent base. The top of the support seat is fixed with a caliper positioning mechanism 402, which includes a pneumatically tightenable caliper. It should be noted that the line connecting the two calipers is set at a certain angle relative to the horizontal plane. The horizontal moving mechanism 401 moves a certain distance towards the flat end of the bar stock and uses the caliper to clamp the flat end of the bar stock, thereby rotating the bar stock to the corresponding angular position.

[0024] like Figure 6 As shown, the feeding conveyor belt transport module 5 includes multiple sets of driving wheels 502 and driven wheels 503. Each set of driving wheels is connected to a triangular conveyor belt 504 to transport the assembled parts. The multiple sets of driving wheels 502 are driven to rotate by a drive motor 501.

[0025] It should be noted that during the actual assembly and positioning process, the accuracy of the guide rail positioning module 2 must be ensured, so that each guide rail in each stage maintains parallelism and angle, ensuring that the bar stock does not deviate from the predetermined trajectory when rolling through the guide rails. Simultaneously, the distance between the guide rails must be properly coordinated to ensure a smooth transition of the bar stock without significant impact; otherwise, vibration will occur, affecting not only the direction of the bar stock's rolling but also potentially causing the ring to deviate from its original position again after assembly.

[0026] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
