Description

一种弹簧成型机的驱动结构技术领域 Driving structure of spring forming machine

本实用新型涉及一种弹簧成型机的驱动结构，该驱动结构采用同步传动机构，实现了只需四组伺服电机便可驱动八组加工滑板。 The utility model relates to a driving structure of a spring forming machine. The driving structure adopts a synchronous transmission mechanism, and realizes that only four sets of servo motors can drive eight sets of processing slides.

背景技术 Background technique

弹簧是最基本的机械零件之一，它在各领域中都有着广泛的应用。弹簧成型机是一种生产弹簧的设备，其上的八组加工滑板驱动方式一般有两种： Spring is one of the most basic mechanical parts, and it has a wide range of applications in various fields. The spring forming machine is a device for producing springs, and there are generally two types of processing methods for the eight sets of processing slides:

第一种方式为，只使用一组伺服电机，通过串连的齿轮和凸轮轴同时驱动八组加工滑板。因为电脑控制***不能自由地控制每一组凸轮轴的位置，所以每一组凸轮轴必须使用不同形状或不同位置的凸轮片来驱动加工滑板，达成所需的加工动作。因此不同形状的弹簧成型是需要不同形状的凸轮片来配合的，结果调校不同的弹簧需要花很长时间来调整凸轮片，增加了整体生产过程时间。由于只使用了一组伺服电机，其优点是设备成本较低。 The first way is to use only one set of servo motors to drive eight sets of machining slides simultaneously through the series of gears and camshafts. Because the computer control system is not free to control the position of each set of camshafts, each set of camshafts must use different shapes or different positions of cam plates to drive the machining slides to achieve the desired machining action. Therefore, the spring forming of different shapes requires the cam pieces of different shapes to be matched. As a result, adjusting the different springs takes a long time to adjust the cam pieces, which increases the overall production process time. Since only one set of servo motors is used, the advantage is that the equipment costs are low.

第二种方式为，使用一组伺服电机独立驱动一组加工滑板，总共使用八组伺服电机驱动八组滑板。采用该方式的优点是，所有加工动作完全由电脑控制而不需要调整凸轮片，大幅减少了调校弹簧的时间，提高了生产效率。但因使用了八组伺服电机，还需配置高级的电脑控制***来同一时间控制八组伺服电机，所以设备成本很高。 The second way is to use a set of servo motors to independently drive a set of machining slides, using a total of eight sets of servo motors to drive eight sets of slides. The advantage of this method is that all machining operations are completely controlled by the computer without the need to adjust the cam piece, which greatly reduces the time for adjusting the spring and improves the production efficiency. However, due to the use of eight sets of servo motors, an advanced computer control system is required to control eight sets of servo motors at the same time, so the equipment cost is high.

对于第二种方式，经过统计，需要同一时间驱动八组加工滑板的情况是不可能出现的，而一般情况下，最多同一时间使用三组加工滑板来对弹簧成型的。 For the second method, after counting, it is impossible to drive eight sets of processing slides at the same time. In general, at most the same time, three sets of processing slides are used to form the springs.

实用新型内容 Utility model content

本实用新型的目的就是针对现有技术存在的不足之处，提供一种可以降低设备成本，提高生产效率的弹簧成型机的驱动结构。 The purpose of the utility model is to provide a driving structure of a spring forming machine which can reduce equipment cost and improve production efficiency in view of the deficiencies of the prior art.

为了实现上述目的，本实用新型所采用的技术方案是：该弹簧成型机的驱动结构包括伺服电机，减速箱，传动机构，凸轮轴组件，凸轮片及加工滑板，实现四组伺服电机驱动八组加工滑板进行加工动作，并且每组伺服电机驱动相邻的两组加工滑板进行加工动作。每组伺服电机连接一减速箱，再连接传动机构，该传动机构为同步传动机构，由伺服电机经减速箱带动同步齿轮，该同步齿轮通过同步带再带动另一同步齿轮，从而驱动两组相邻的加工滑板。这样每组伺服电机驱动两组相邻的加工滑板进行加工动作，共需四组伺服电机即可驱动八组加工滑板进行加工动作。以上弹簧成型机的驱动结构中，每两组通过同步传动机构联动的凸轮片，其相对位置为相互错开一定角度，经过对凸轮片的此种特定安排，可同一时间容许最多四组加工滑板进行加工动作。该驱动结构的凸轮片为无需调整其形状或位置的凸轮片，可应对不同弹簧的调校，电脑控制***亦可自由地控制加工滑板的动作和位置。 In order to achieve the above object, the technical solution adopted by the utility model is: the drive structure package of the spring forming machine Including servo motor, reducer, transmission mechanism, camshaft assembly, cam plate and machining slide, four sets of servo motors drive eight sets of processing slides for machining, and each set of servo motors drives adjacent two sets of processing slides for machining . Each set of servo motor is connected to a speed reducer, and then the transmission mechanism is connected. The transmission mechanism is a synchronous transmission mechanism. The servo motor drives the synchronous gear through the reduction gear box. The synchronous gear drives another synchronous gear through the synchronous belt to drive the two sets of phases. The adjacent processing skateboard. In this way, each group of servo motors drives two sets of adjacent processing slides to perform machining operations, and four sets of servo motors are required to drive eight sets of processing slides for processing. In the driving structure of the above spring forming machine, each of the two sets of cam pieces that are linked by the synchronous transmission mechanism are in a relative position offset from each other by a certain angle. After such specific arrangement of the cam pieces, up to four sets of processing slide plates can be allowed at the same time. Processing action. The cam piece of the driving structure is a cam piece that does not need to adjust its shape or position, and can cope with the adjustment of different springs, and the computer control system can also freely control the action and position of the processing slide plate.

弹簧成型机采用该种驱动结构，由四组伺服电机驱动八组加工滑板进行加工动作，且无需调整凸轮片的形状或位置，既降低了设备成本，又提高了生产效率。 The spring forming machine adopts the driving structure, and the four sets of servo motors drive eight sets of processing slides for processing, and the shape or position of the cam pieces need not be adjusted, thereby reducing the equipment cost and improving the production efficiency.

具体实施方式 detailed description

参照图 1和图 2，弹簧成型机的驱动结构主要由伺服电机 1，减速箱 2，同步齿轮 3 , 同步带 4, 同步齿轮 5，凸轮片 6，凸轮轴组件 7，加工滑板 8组成。伺服电机 1连接减速箱 2，再连接传动机构，该传动机构由同步齿轮 3和 5及同步带 4组成，同步齿轮.3 和 5各连接一个凸轮轴组件 7和一个凸轮片 6。弹簧成型机工作时，通过伺服电机 1的旋转，经减速箱 2带动同步齿轮 3旋转，同步齿轮 3通过同步带 4再带动同步齿轮 5同步旋转，同步齿轮 3和 5分别经凸轮轴组件 7来转动凸轮片 6, 转动的凸轮片 6便可驱动加工滑板 8作加工动作。参照图 1和图 2，每组伺服电机 1驱动相邻的两组加工滑板 8进行加工动作，共需四组伺服电机即可驱动八组加工滑板进行加工动作。 Referring to Figures 1 and 2, the driving structure of the spring forming machine is mainly composed of a servo motor 1, a reduction gear box 2, a synchronizing gear 3, a timing belt 4, a synchronizing gear 5, a cam plate 6, a cam shaft assembly 7, and a machining slide 8. The servo motor 1 is connected to the reduction gear box 2, and is connected to a transmission mechanism composed of the synchronizing gears 3 and 5 and the timing belt 4, and the synchronizing gears 3 and 5 are each connected to a camshaft assembly 7 and a cam plate 6. When the spring forming machine is in operation, the synchronous gear 3 is rotated by the reduction gear box 2 through the rotation of the servo motor 1, and the synchronous gear 3 drives the synchronous gear 5 to rotate synchronously through the timing belt 4, and the synchronous gears 3 and 5 respectively pass through the camshaft assembly 7. By rotating the cam piece 6, the rotating cam piece 6 can drive the processing slide 8 to perform a machining operation. Referring to Figures 1 and 2, each set of servo motors 1 drives adjacent two sets of processing slides. 8 For the machining operation, a total of four sets of servo motors are required to drive eight sets of processing slides for machining operations.

图 3至图 5给出了两组关联的凸轮片 6的相对位置及加工滑板 7的相应加工位置的关系图。在伺服电机 1处于原点时，两组关联的凸轮片 6的位置参照图 3，其相对位置为相互错开一定角度，此时两组加工滑板 8退到最后位置。当伺服电机 1旋转到 + 180 度时，两组凸轮片 6的位置参照图 4, 此时一组加工滑板 8被推动到加工位置。当伺服电机 1旋转到一 180度时，两组凸轮片 6的位置参照图 5，此时另一组加工滑板 8被推动到加工位置。在这样的编排下两组加工滑板是不会同时间被推动的，再配合其他六组加工滑板，同一时间可容许最多四组加工滑板进行加工动作。当然，还可以对每两组关联的凸轮片 6采用其他的相对位置，这样的变化均落在本实用新型的保护范围之内。 Figures 3 to 5 show the relationship between the relative positions of the two sets of associated cam segments 6 and the corresponding machining positions of the machining slide 7. When the servo motor 1 is at the origin, the positions of the two sets of associated cam pieces 6 are as shown in Fig. 3, and their relative positions are shifted from each other by a certain angle, at which time the two sets of processing slides 8 are retracted to the final position. When the servo motor 1 is rotated to +180 degrees, the positions of the two sets of cam sheets 6 are as shown in Fig. 4, at which time a group of processing slides 8 are pushed to the machining position. When the servo motor 1 is rotated to a 180 degree, the positions of the two sets of cam plates 6 are as shown in Fig. 5, at which time the other set of the machining slides 8 are pushed to the machining position. Under such arrangement, the two sets of processing slides will not be pushed at the same time. Together with the other six sets of processing slides, up to four sets of processing slides can be allowed to perform the processing at the same time. Of course, it is also possible to use other relative positions for each of the two sets of associated cam segments 6, and such variations are within the scope of the present invention.
