Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying technology, and more specifically, to a precision chain plate module with high planar accuracy. Background Technology
[0002] Chain conveyor lines are a common type of industrial automated conveying equipment. They use a motor to drive a chain, which in turn moves chain plates fixed to the chain, thus conveying workpieces. Traditional chain conveyor lines are widely used in the food, beverage, pharmaceutical, and daily chemical industries.
[0003] However, in applications such as precision electronics, semiconductors, automotive precision component assembly, laser welding, laser cleaning, or high-precision visual inspection, extremely high requirements are placed on the flatness, rigidity, and operational stability of the conveyor platform. Existing conventional chain conveyor lines have the following drawbacks: 1. Poor planar accuracy: Chain plates are usually supported only by chains. The deflection of the chain itself and the clearance of the pins will cause the chain plates to sink and shake when under load, forming a "wavy" uneven surface, which cannot provide a stable reference plane for precision workpieces.
[0004] 2. Insufficient rigidity: Under heavy load or uneven force, the chain plate is prone to deformation, which further deteriorates the flatness accuracy.
[0005] 3. Unstable operation: The meshing of the chain and the drive sprocket, as well as the friction of the guide rail, can easily cause vibration and noise during the conveying process, which is not suitable for the process requirements of high-precision workstations. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, this utility model provides a precision chain plate module with high planar accuracy, which solves the defects pointed out in the background art above.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-precision chain plate module with high planar accuracy, including a frame, a drive motor fixedly installed at the front end of the frame, sprockets rotatably connected to both the left and right ends of the frame, a chain drivingly connected to the surface of the sprockets, and a plate chain provided on the chain; It also includes a high-precision planarity assurance system, which includes a support base, a slider, and a guide rail; The support base is mounted on the frame, the slider is mounted on the support base, and the guide rail is fixedly mounted on one end of the plate chain near the center of the frame.
[0008] As a preferred embodiment of this utility model, multiple sliders are provided, and the multiple sliders are connected to the support base, with the guide rail slidably connected inside the slider.
[0009] In a preferred embodiment of this invention, the slider is fixed to the support base by screws, and the support base is fixed to the frame by screws.
[0010] As a preferred embodiment of this utility model, the frame is provided with a slide rail, and the chain is placed inside the slide rail.
[0011] As a preferred embodiment of this utility model, mounting seats are provided on both the front and rear sides of the plate chain near the center of the frame. The mounting seats are hinged to the chain, and the plate chain and the mounting seats are connected by adjustable fasteners.
[0012] As a preferred embodiment of this utility model, the area on the plate chain located between the mounting bases is a leveled area.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model directly supports and guides each plate chain through high-precision sliders and guide rails, completely eliminating the influence of chain deflection, gaps and deformation on the chain plane, ensuring that the entire leveling area always maintains extremely high flatness (reaching ±0.05mm or even higher).
[0014] 2. The slider in this utility model has extremely high rigidity, which can effectively resist bending and torsional deformation caused by load, providing a solid and stable platform for precision operations (such as tightening, pressing, measuring, welding, cleaning).
[0015] 3. The slider and guide rail of this utility model have a low coefficient of friction, resulting in smooth movement and significantly reducing vibration and noise during equipment operation, making it suitable for environments with high cleanliness and quiet requirements.
[0016] 4. The slider in this utility model is a standardized and mature component with good wear resistance and long service life, which greatly reduces the maintenance cost and downtime of the equipment. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1 to 3 As shown, this utility model provides a high-precision chain plate module with high planar accuracy, including a frame 1, a drive motor 2 fixedly installed at the front end of the frame 1, sprockets 3 rotatably connected to both the left and right ends of the frame 1, a chain 4 being driven to the surface of the sprockets 3, and a plate chain 5 being provided on the chain 4. It also includes a high-precision planarity assurance system, which includes a support base 6, a slider 7, and a guide rail 8; The support base 6 is mounted on the frame 1, the slider 7 is mounted on the support base 6, and the guide rail 8 is fixedly mounted on one end of the plate chain 5 near the center of the frame 1.
[0021] The slider 7 is configured according to the required conveying length. Multiple sliders are used in combination to support and guide the chain 5. High-precision sliders 7 and guide rails 8 directly support and guide each piece of the chain 5, completely eliminating the influence of chain 4 deflection, gaps, and deformation on the chain 4's plane. This ensures that the entire leveling area 9 maintains extremely high flatness (achieving ±0.05mm or even higher). The slider 7 has extremely high rigidity, effectively resisting bending and torsional deformation under load, providing a solid and stable platform for precision operations (such as tightening, pressing, measurement, welding, and cleaning). The slider 7 and guide rails 8 have a low coefficient of friction, resulting in smooth movement and significantly reducing vibration and noise during equipment operation, making it suitable for environments requiring high cleanliness and quietness. The slider 7 is a standardized and mature component with good wear resistance and a long service life, greatly reducing equipment maintenance costs and downtime.
[0022] Multiple sliders 7 are provided, and multiple sliders 7 are connected to the support base 6. The guide rail 8 is slidably connected inside the slider 7.
[0023] Chain 4 is located on both sides of slider 7. Plate chain 5 is constrained on slider 7 by mounting base 10 and guide rail 8 to make linear motion. Slider 7 provides continuous and stable support for plate chain 5 throughout the entire process, thereby ensuring that all plate chains 5 together form a high-precision conveying plane.
[0024] The slider 7 is fixed to the support base 6 by screws, and the support base 6 is fixed to the frame 1 by screws.
[0025] The slider 7 is one of the following: linear guide, precision-ground hard chrome rectangular guide, or dovetail groove. The screws used for installation and connection between the frame 1, support base 6 and slider 7 must be parallel and level during installation to ensure installation stability.
[0026] The frame 1 is equipped with a slide rail, and the chain 4 is placed inside the slide rail.
[0027] The slide rail is used to support and guide the movement of chain 4. The slide rail is a strip structure such as a dovetail groove that can provide guidance and support.
[0028] Among them, the plate chain 5 is provided with mounting seats 10 on both the front and rear sides near the center of the frame 1. The mounting seats 10 are hinged to the chain 4, and the plate chain 5 and the mounting seats 10 are connected by adjustable fasteners.
[0029] Mounting base 10 is hinged to chain 4 via connector, allowing chain 4 to drive the entire plate chain 5 to move, so that the guide rail 8 under plate chain 5 enters the slider group composed of multiple sliders 7 on support base 6 for precise sliding.
[0030] Among them, the area on the plate chain 5 located between the mounting bases 10 is the leveling area 9.
[0031] Adjustable connection via fasteners facilitates fine-tuning of the height of the single-plate chain 5, enabling smooth engagement between the adjustment guide rail 8 and the slider 7, resulting in a high overall flatness of the entire leveling area 9.
[0032] Working principle and usage process of this utility model: The drive motor 2 provides power to drive the sprocket 3 to rotate the chain 4, which in turn drives the plate chain 5 to rotate and transport. When the plate chain 5 rotates and transports, the plate chain 5 and the guide rail 8 are completely supported and guided by the high-rigidity slider 7, maintaining the high-precision flatness and stability of the leveling area 9. The chain 4 and the sprocket 3 are only responsible for driving and traction, and do not undertake the support and guidance functions. Therefore, the high-precision flatness and stability of the leveling area 9 are completely determined by the accuracy and installation accuracy of the guide rail 8 and the slider 7, and are independent of the state of the chain 4, thus achieving a stable and reliable high-precision conveying plane.
