[0019] As attached Figure 1 To be continued Figure 4 The present invention discloses a bridge package expansion core clamping device, including a guide component 1 and a positioning component 2, wherein the positioning component 2 is assembled on the top of the guide component 1. Example
[0020] Specifically, in the guide assembly 1, a support plate 12 is symmetrically arranged at the bottom of the support base 11, and a base 13 is arranged at the bottom of the support plate 12. The function of this connection structure is to firmly connect the support base 11 and the base 13 through the support plate 12, forming the basic support structure of the guide assembly 1, providing a stable installation benchmark for the entire device, and ensuring that the device is not prone to shaking during operation.
[0021] Two sets of fixing plates 14 are symmetrically installed on the top of the support base 11. Hinges 15 are respectively set on the top of the fixing plates 14. The function of this connection is to use the fixing plates 14 to provide a stable mounting carrier for the hinges 15, and at the same time, the symmetrical arrangement ensures that the hinges 15 are subjected to balanced forces, providing reliable support for the subsequent installation of the adjustment structure and positioning component 2.
[0022] In addition, an adjusting bolt 18 is provided through the middle of the hinge seat 15. One end of the adjusting bolt 18 is threaded to an adjusting nut 19. The function of this connection is to adjust the installation angle and position of the hinge seat 15 by adjusting the thread engagement between the adjusting bolt 18 and the adjusting nut 19, thereby achieving fine adjustment of the overall posture of the guide assembly 1 and ensuring that the positioning assembly 2 can be accurately aligned with the bridge package to be clamped.
[0023] Furthermore, a fixed seat 16 is installed at the top of the hinge seat 15, and rollers 17 are symmetrically and movably mounted at the top of the fixed seat 16. The function of this connection is that the fixed seat 16 provides installation support for the rollers 17. The rollers 17 adopt a movable connection method, which can roll with the slight displacement of the bridge package during the clamping process, effectively reducing frictional loss between the bridge package and the rollers 17, and avoiding damage to the surface of the bridge package due to friction. Example
[0024] Based on Example 1, in order to further avoid positioning offset and ensure the positioning accuracy of the bridge package, a positioning component is set at the top of the guide component.
[0025] Specifically, in the positioning component 2, the bottom end of the positioning cylinder 21 is provided with a mounting seat, which is located at the top of the hinge seat 15. The function of this connection is to securely install the positioning cylinder 21 at the top of the hinge seat 15 through the mounting seat, so that the positioning component 2 and the guide component 1 form a unified whole, ensuring that the positioning component 2 and the guide component 1 are subjected to force synchronously during the operation, thereby improving the overall stability of the device.
[0026] The positioning cylinder 21 has three sets of connecting plates 22 symmetrically arranged inside. One end of the connecting plate 22 has a groove. The function of the connecting plate 22 is to serve as the internal support structure of the positioning component 2. The symmetrical arrangement of the three sets of designs can ensure that the positioning force is uniform. The groove provides a stable sliding trajectory for the movable block 24, ensuring that the movable block 24 will not deviate during the movement.
[0027] In addition, one end of the electric push rod 23 is movably connected to the bottom end of the connecting plate 22, and the other end of the electric push rod 23 is equipped with a movable block 24. The function of this connection is that the connecting plate 22 provides a fixed support point for the electric push rod 23. As a power actuator, the electric push rod 23 can directly drive the movable block 24 to move linearly through telescopic movement, providing a power source for the position adjustment of the positioning plate 28.
[0028] Furthermore, the movable block 24 is adapted to the slide groove, and the two ends of the movable block 24 are symmetrically connected to the connecting rod 27. The other end of the connecting rod 27 is movably connected to one end of the positioning plate 28. The function of this connection is that the slide groove guides and limits the movable block 24, ensuring that the movable block 24 slides stably along the preset trajectory. The connecting rod 27, as a power transmission component, converts the linear motion of the movable block 24 into the opening and closing motion of the positioning plate 28, thereby realizing the clamping or releasing action of the bridge package.
[0029] Furthermore, one end of the positioning plate 28 is movably connected to connecting rod 25, and the other end of connecting rod 25 is movably connected to one end of the connecting plate 22. A second connecting rod 26 is provided on one side of connecting rod 25. One end of the second connecting rod 26 is movably connected to one end of the connecting plate 22, and the other end of the second connecting rod 26 is movably connected to the positioning plate 28. The function of this connection is to form a linkage structure with connecting rod 25 and connecting rod 26, which enhances the structural stability of the positioning plate 28 during the adjustment process, prevents the positioning plate 28 from tilting due to unilateral force, and ensures the positioning accuracy of the positioning plate 28 for the bridge package.
[0030] Furthermore, anti-slip pads are symmetrically arranged at the bottom of the base 13. The function of these anti-slip pads is that they are made of nitrile rubber and have diamond-shaped anti-slip patterns on the surface, which can increase the friction between the base 13 and the mounting surface, effectively preventing the device from shifting due to vibration during operation, and further improving the overall installation stability of the device.
[0031] Furthermore, a buffer pad is provided on the side of the positioning plate 28 away from the first link 25, the second link 26, and the third link 27. The function of this connection is that the buffer pad is made of polyurethane foam, which plays a buffering role when the positioning plate 28 contacts the bridge axle, avoiding excessive clamping force from causing squeezing damage to the surface of the bridge axle, while enhancing the fit between the positioning plate 28 and the bridge axle and improving clamping stability.
[0032] It should also be noted that the bridge package expansion core in this application can be a small lightweight bridge package, a medium-sized general-purpose bridge package, or a large heavy-duty bridge package, etc. Figure 1 In this embodiment, a small and lightweight bridge package expansion core is used as an example for description. Of course, other types of bridge package expansion cores can also adopt similar structures, which will not be described in detail below.
[0033] Understandable Figure 1The clamping device is shown only schematically, and the actual shape, size, position, and construction of these components are not subject to change. Figure 1 Due to limitations, the clamping device may also include, compared to Figure 1 More or fewer parts.
[0034] In practical use, the device is first placed firmly on the workbench by the anti-slip pad at the bottom of the base 13. The diamond-shaped anti-slip pattern of the anti-slip pad increases the friction and prevents the device from shifting, providing a stable foundation for the subsequent automatic position adjustment of the workpiece. According to the specifications of the bridge bag and the position to be processed, the installation angle and position of the hinge seat 15 are finely adjusted by adjusting the threaded engagement of the adjusting bolt 18 and the adjusting nut 19, so that the positioning component 2 is initially aligned with the clamping area of the bridge bag. At this time, the fixing plate 14 provides stable support for the hinge seat 15, ensuring that the adjusted position remains fixed, and reserving adaptation space for the automatic adjustment of the workpiece.
[0035] When the bridge package workpiece is placed on the roller 17 at the top of the fixed base 16, the roller 17 adopts a movable connection method and can roll as the bridge package workpiece is placed. If there is a deviation in the initial placement position of the workpiece, the rolling characteristics of the roller 17 will assist the workpiece to make a small displacement under its own weight and slight external force, and initially achieve position calibration. At the same time, the three sets of symmetrically arranged connecting plates 22 and the slide groove structure in the positioning component 2 provide a guiding basis for the subsequent precise adjustment of the workpiece, so that the workpiece can gradually approach the optimal clamping area along the rolling direction of the roller 17 and complete the initial automatic positioning.
[0036] After the electric push rod 23 is activated, it begins to extend and retract under the support of the connecting plate 22, driving the movable block 24 to slide stably along the groove on the connecting plate 22. The groove guides and limits the movable block 24, ensuring that the movable block 24 drives the subsequent components to move along the preset trajectory. When the movable block 24 moves, the connecting rods 27 at both ends are synchronously driven, driving the positioning plate 28 to move closer to the workpiece. During this process, if there is still a slight positional deviation in the workpiece, the side of the positioning plate 28 that first contacts the workpiece will generate a slight guiding thrust on the workpiece through the elastic contact of the buffer pad. Combined with the rolling characteristics of the roller 17, the workpiece is automatically adjusted to the center symmetrical position of the three sets of positioning plates 28, which is the optimal clamping position. At the same time, the connecting rod 25 and the connecting rod 26 work together to form a linkage support, ensuring that the positioning plate 28 remains stable when pushing the workpiece for adjustment, avoiding workpiece displacement due to unilateral force, and further ensuring the automatic positioning accuracy.
[0037] When the buffer pad on the positioning plate 28 is fully in contact with the surface of the bridge package workpiece, the workpiece is precisely in the optimal clamping position. The buffer pad absorbs excess clamping force through its own elasticity to avoid damaging the workpiece, while enhancing the fit between the positioning plate 28 and the workpiece. The displacement of the movable block 24 is adjusted by the electric push rod 23 until the positioning plate 28 forms a stable expansion clamping state on the bridge package workpiece. The three sets of positioning plates 28 are evenly stressed to ensure that the workpiece remains stable in the optimal clamping position. At this time, the entire device remains stable and subsequent cutting, drilling and other processing steps can be performed. It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
