Description

Technical Field

[0001] The utility model relates to the technical field of parts clamping mechanisms, in particular to a clamping mechanism for processing plate-like parts. Background Art

[0002] In the process of clamping plate-like parts, the prior art device generally places the plate-like parts on a specific processing table, and constrains the position of the plate-like parts through a clamping plate with a tenon structure.

[0003] However, in the design process of conventional processing tables, only the comfort of the user is considered, that is, the design height is generally flush with the waist height of an adult male, which makes it easier for operators to place plate-like parts on it. However, this design idea causes the operator's eyes to be far away from the processing table. When the operator initially positions the parts, he must lean over to observe closely, which is very inconvenient for some operators.

[0004] Therefore, we believe that there is a need for a clamping mechanism for processing plate-like parts that can synchronously adjust the height during the clamping process so that the loading and unloading process and the observation process are both ergonomic. Summary of the invention

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] Please refer to Figure 1-6 A clamping mechanism for processing plate-like parts includes a mounting plate 6. In practice, the mounting plate 6 should be fixedly connected to the workbench, that is, in practice, the mounting plate 6 is set as the basic fixing point of the device, and its position cannot be changed.

[0027] Therefore, the device is provided with an up-and-down axial telescopic rod 7 on the mounting plate 6, and the up-and-down movement of the telescopic rod 7 is controlled by a cylinder, which can drive a follower plate 8 located above the telescopic rod 7 and fixedly connected to the telescopic rod 7 to move up and down linearly.

[0028] At the same time, in order to realize the clamping process, the device is respectively provided with clamping plates 1 on the left and right sides of the upper end of the mounting plate 6. By changing the distance between the two clamping plates 1, the plate-like parts can be clamped. By changing the upper and lower positions of the two clamping plates 1, the height of the plate-like parts can be changed, thereby realizing the adaptation of the clamping position and the processing position.

[0029] Furthermore, as shown in the figure, the two clamping plates 1 are respectively fixedly connected with rubber cushions at their proximal ends, so as to prevent the clamping plates 1 from being damaged by a rigid collision with the clamping parts through the cushions.

[0030] In addition, the device constrains the two clamping plates 1 to have tenon-shaped end faces near their ends, and the width of the middle section of each clamping plate 1 is smaller than the width of the upper and lower end faces. This can utilize the inclined structure of the tenon-shaped end faces to apply reverse thrusts in the upper and lower directions to the clamped parts, thereby applying upper and lower constraints to the clamped parts.

[0031] Specifically, the device is provided with four follower rods 4 in a rectangular array on the mounting plate 6, and a limiting ring 5 is sleeved on the outer side of each follower rod 4. The movement trajectory of the follower rod 4 is constrained by fixedly connecting the limiting ring 5 to the mounting plate 6. At this time, by limiting the angle between the lower end surface of the inner cavity of the limiting ring 5 and the horizontal plane and the vertical plane to be not equal to zero, the inclined movement of the follower rod 4 can be achieved, so that the two clamping plates 1 can synchronously achieve upward and approaching movement, or achieve synchronous downward and away movement of the two clamping plates 1.

[0032] Furthermore, the device constrains each follower rod 4 to be a rectangular structure, and the angle between the lower end surface of each follower rod 4 and the horizontal plane is greater than thirty degrees and less than sixty degrees. This, combined with the adaptability between the inner cavity of the limit ring 5 and the follower rod 4, can fully ensure that when the follower rod 4 is subjected to a force in the vertical direction, the movement trajectory of the follower rod 4 meets the requirements, and the follower rod 4 will not be unable to operate as expected due to excessive friction resistance.

[0033] Furthermore, in order to reduce the frictional resistance between the driven rod 4 and the limiting ring 5, the device has an installation groove running through each driven rod 4, and a plurality of rolling rings 17 are embedded in the installation groove and arranged equidistantly along the length of the driven rod 4 and in the front-to-back axial direction. At this time, the inner cavity height of the limiting ring 5 is greater than the diameter of the rolling ring 17, and the thickness of the driven rod 4 is less than the diameter of the rolling ring 17, so that the driven rod 4 does not directly contact the limiting ring 5, and the rolling ring 17 is rotationally connected to the driven rod 4 to achieve a rolling connection with the limiting ring 5, which can effectively reduce the frictional resistance during the relative movement between the driven rod 4 and the limiting ring 5.

[0034] At the same time, due to the structural characteristics of the rolling ring 17 itself, it reduces the friction resistance between the rolling ring 17 and the limit ring 5 by reducing the contact area. Therefore, in order to always ensure that the rolling ring 17 is in contact with the limit ring 5, rather than rotating the driven rod 4 to make the driven rod 4 contact with the limit ring 5, this device constrains the width of the limit ring 5 to be greater than 1.5 times the outer diameter of the rolling ring 17, so that the inner wall of the limit ring 5 is in contact with multiple rolling rings 17. This can use multiple support points to fully constrain the driven rod 4 from changing the inclination angle relative to the limit ring 5.

[0035] Specifically, in order to realize the connection process between the driven rod 4 and the clamping plate 1, the device is fixedly connected with the mounting rod 2 at the upper end of the driven rod 4 through the connecting rod 3, and the mounting rod 2 is movably connected to the clamping plate 1, thereby realizing the linkage effect of the driven rod 4 and the clamping plate 1, that is, when the driven rod 4 moves up and down and horizontally, it can drive the clamping plate 1 to move synchronously.

[0036] Furthermore, in order to avoid travel conflicts and allow the driven rod 4 to have a larger range of motion to comply with the application operation process, the device has a through slot 10 running through the mounting rod 2, and each through slot 10 is embedded with a movable rod 11 having an L-shaped structure in vertical plane projection.

[0037] Therefore, by constraining the inflection point position on the movable rod 11 to be rotatably connected to the mounting rod 2 through the pin shaft 9, that is, the horizontal section of the movable rod 11 passes through the through slot 10, and the vertical section of the movable rod 11 is fixedly connected to the clamping plate 1, the clamping plate 1 can undergo a slight relative movement relative to the driven rod 4.

[0038] Furthermore, in the device, a hook spring 13 is movably connected to the upper end of the part of the horizontal section of the movable rod 11 that protrudes from the through groove 10, and the other axial end of the constraint hook spring 13 is movably connected to the mounting rod 2, so that the hook spring 13 provides an initial pulling force for the movable rod 11, ensuring that in the initial state, the angle of the two clamping plates 1 can meet expectations.

[0039] Furthermore, the device is also fixedly connected with a front-to-rear axial limit shaft 12 in each through groove 10, and the two limit shafts 12 are constrained to be located at the far ends of the two movable rods 11 respectively. This can further constrain the movement range of the movable rod 11 and ensure that the tenon end face of the clamping plate 1 can contact the workpiece to be processed.

[0040] Specifically, in order to realize the up and down and horizontal movement of the driven rod 4, the device is respectively provided with front and rear axial fixed shafts 16 on the front and rear sides of the upper end of the mounting plate 6, so that the two driving rods 14 in the same vertical plane are constrained to be rotatably connected through the fixed shafts 16, and a pull rod 15 is sleeved on the outer side of each fixed shaft 16, and the two pull rods 15 are fixedly connected to the follower plate 8. Therefore, the pull rod 15 can be driven by the telescopic rod 7 and then the limit ring 5 can be used to realize the up and down and horizontal movement of the driven rod 4.

[0041] In actual use, the utility model:

[0042] First, the operator turns on the corresponding driving device to reduce the vertical length of the telescopic rod 7. At this time, the follower plate 8 moves downward synchronously, that is, the two clamping plates 1 move away from each other.

[0043] Then, the operator holds the workpiece to be processed and places it between the two clamping plates 1. At this time, the corresponding driving device is turned on in the reverse direction, and the two clamping plates 1 move upward towards each other and synchronously;

[0044] Finally, when the workpiece to be processed moves to a suitable position, the corresponding driving device is turned off. At this time, the buffer pad is in a compressed state and the hook spring 13 is in a stretched state.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
