Unless defined otherwise, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. As used herein, the term "and/or" includes one or more related combinations.
First embodiment
The product of the embodiment aims to realize the synchronous movement of different devices. Referring to fig. 1, fig. 1 is a schematic diagram of a basic embodiment of the present invention.
The utility model discloses the product is including fixed subassembly, removal subassembly, wherein:
the fixed component is fixedly connected with a workbench (omitted in the figure), and the function of the fixed component is to provide support for the rest components. In actual work, the fixed component can be fixedly arranged on a workbench through welding, and the workbench can be a rack, a moving platform, a shell, firm ground and even any place needing to move synchronously, which belongs to the common technical means in the technical field. In this embodiment, the fixing component comprises the rails in fig. 1, and includes a first rail 12 and a second rail 15, and the moving component of the product of this embodiment operates under the support of the first rail 12 and the second rail 15.
To the utility model discloses, the effect of track 1,15 in the fixed subassembly is the motion trail of guide restriction removal subassembly, makes slide 2,6,10 move through first slider 16 limitedly. Therefore, the rails do not necessarily have to be symmetrically arranged in pairs in the manner of the present embodiment. For example, the second rail 15 may be omitted, and a combined rolling frame may be provided at a position corresponding to each of the slideways 2,6,10, so that the first rail 12 alone provides the restriction and guidance of the movement locus.
The moving assembly is mounted on the fixed assembly. The moving assembly should include at least three slides, shown as a first slide 2, a second slide 6, and a third slide 10. The slideways 2,6,10 slide on the rails 12,15 by means of first sliding means 16 at both ends. In the present embodiment, a combination roller frame is selected as the sliding device 16.
In order to limit the stroke of the moving assembly and improve the stability of the overall device, limit blocks may be disposed on the rail, so that the moving assembly is only allowed to run between the limit blocks, such as the first limit block 1, the second limit block 13, the third limit block 14, and the fourth limit block 17 in the drawing.
Two moving rods are arranged between the adjacent slideways (if two long moving rods A4 are arranged between the first slideway 2 and the second slideway 6 and two long moving rods B8 are arranged between the second slideway 6 and the third slideway 10), and the two moving rods are connected in a cross way to form a revolute pair, so that the two connected moving rods can rotate relatively around a common shaft. Meanwhile, second sliding means 3,7,11 are provided at both ends of the moving rods 4,8, respectively. Two crossed connecting moving rods are respectively installed on two adjacent slideways through four second sliding devices (for example, a long moving rod A4 is installed on a first slideway 2 through a first slide block 3, a long moving rod B8 is installed on a third slideway 10 through a third slide block 11, and a second slide block 7 shared by the long moving rod A4 and the long moving rod B8 is installed on a second slideway 6), so that the second sliding devices can slide along the slideways. The common axes of the intersecting travel bars (first and second alignment pins 5,9 in the figures) will remain stationary as the adjacent runners move toward or away from each other. In other words, the common axis of each pair of the crossed moving rods is a positioning point for ensuring the mechanism to move synchronously, and the user can increase the number of the crossed moving rods and the number of the slideways according to the requirement, that is, the number of the positioning points can be correspondingly increased (in the figure, the first positioning pin 5 is the first positioning point, and the second positioning pin 9 is the second positioning point).
Further, in order to limit the moving direction of the common axis of the moving levers, the moving locus of the common axis (positioning pins 5, 9) may be limited. For example, the positioning pins 5,9 can move in a limited linear motion by using a linear guide as a fixing component, the guide rail is parallel to the rails 12,15, the positioning pins 5,9 are extended, and the extended parts of the positioning pins are connected with the sliding blocks of the linear guide.
In the simplest simultaneous movement mechanism, the spacing between the slides is increased or decreased simultaneously and equidistantly. At this time, it is only necessary to make a force act on the first positioning pin 5 to provide a reaction force (or friction force) at the second positioning pin 9, and the pitches of the first slider 3, the second slider 7, and the third slider 11 are relatively close to or far from each other by the deformation of the moving rod. The first positioning pin 5 and the second positioning pin 9 can move on the same straight line. Of course, the acting force and the counterforce for the operation of the driving mechanism can be applied to other components, and the utility model is not repeated.
Second embodiment
The purpose of the second embodiment is to expand the application of the first embodiment.
Referring to fig. 1 and 5, in the foregoing embodiment, the positioning pins are supported by two adjacent runners and are disposed at intermittent positions of the two runners, for example, the first positioning pin 5 is disposed between the first runner 2 and the second runner 6. In order to further utilize the synchronous moving device, reasonably add the synchronous moving point, the end slide, that is, the slide (the first slide 2 and the third slide 10 in the figure) with the adjacent slide on only one side, can be provided with a moving rod at the other end, and the moving rod can adopt a shorter short rod in structure, unlike the moving rod between the adjacent slides, and for the difference from the previous embodiment, the moving rod between the adjacent slides is called as a long moving rod 4,8, and the moving rod outside the end slide is called as a moving short rod 19.
The short travel bar 19 is connected in a slightly different manner to the long travel bars 4,8, since it is connected to the slide on one side only. As shown in the figure, one end of the two short moving rods 19 is hinged to form a revolute pair, and the other end of the short moving rod 19 is connected to the second sliding device (the first sliding block 3) through a hinge. If a positioning pin 18 is provided at the hinge of the two short moving rods 19, the positioning pin 18 can also move with the other positioning pins 5, 9.
Third embodiment
One of the purposes of the design of the utility model is to provide a scheme for the movement of the cover sheet of the machine tool protection. Therefore, after the connection relation between the fixed component and the movable component in the synchronous moving mechanism is solved, the utility model discloses the connection mode of the machine tool protective cover piece is briefly explained.
The foregoing embodiment has described in detail how to implement the simultaneous movement of the positioning pins, and in practical applications, the simultaneous movement of the components can be implemented by simply mounting the components requiring the simultaneous movement on the positioning pins.

Correspondingly, the initial mask sheet 20, the middle mask sheet 21 and the end mask sheet 22 are all provided with positioning holes 23. After the cover sheets are mounted on the positioning pins 5,9 and 18 through the positioning holes 23, the cover sheets are fixedly connected with the positioning pins through welding and other modes, so that the cover sheets are driven to move synchronously when the positioning pins move synchronously.
The utility model discloses an each cover piece welding can guarantee the steady operation of each cover piece on the location site.
