Description

Technical Field

[0001] The utility model relates to the field of clamping mechanisms, in particular to a quick clamping mechanism for mechanical manufacturing. Background Art

[0002] In the mechanical manufacturing process, during the process of assembling mechanical products, the clamping mechanism refers to a mechanism that applies pressure to the edge of the workpiece's foot to fix the workpiece on the workbench, making it easier for workers to assemble the workpiece.

[0003] The existing quick clamping structure for mechanical manufacturing is generally connected to the pressure strip structure on the workbench, and the clamping bolt that can slide along the length direction of the pressure strip is slidably adjusted. After it is close to the foot of the workpiece and tightened, quick clamping of one side of the workpiece can be achieved. For the other side of the workpiece, a clamping plate that can be slidably adjusted in position needs to be provided. After the clamping plate is slid and adjusted to a position close to the workpiece, the other side of the workpiece is clamped.

[0004] With respect to the above-mentioned related technologies, in the process of clamping the workpiece, the existing quick clamping structure for mechanical manufacturing generally requires the clamping block to be tightened twice. One tightening is to limit the horizontal sliding of the clamping plate to position it close to the workpiece foot, and the other tightening is to press the clamping plate toward the edge of the workpiece foot and tighten it in the vertical direction. In summary, when the existing quick clamping mechanism is performing the workpiece clamping work, it is necessary to tighten both sides of the workpiece multiple times. Similarly, to loosen the workpiece, it is also necessary to loosen multiple bolts, which increases the workload and easily affects the clamping speed of the clamping mechanism. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a rapid clamping mechanism for mechanical manufacturing, so as to solve the technical problem that the existing rapid clamping mechanism has a complicated working process, resulting in a slow clamping speed.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick clamping mechanism for mechanical manufacturing, comprising a workbench, one end of the top surface of the workbench is fixedly connected to a fixed table, and a sliding table parallel to the fixed table is slidably connected to the top surface, and slider grooves are arranged in the fixed table and the sliding table along the length direction, and at least one slider is slidably connected in the slider groove, and a fastening bolt passes through the slider in the vertical direction, and a friction plate is sleeved on the bottom end of the fastening bolt, and the friction plate is located below the slider but not in contact with the slider, and the upper ends of the fastening bolts are all passed through a pressing plate structure.

[0007] By adopting the above technical solution, the friction plate contacts the inner wall of the slider groove of the pressing table structure while the pressing plate on the sliding block is pressed down, thereby realizing the pressing down of the pressing plate and the positioning of the sliding block simultaneously, which greatly reduces the time for tightening and loosening the bolts of the clamping structure and effectively improves the clamping speed of the clamping mechanism.

[0008] The utility model is further configured as follows: a sliding groove is provided on the surface of the workbench, a driving screw is rotatably provided in the sliding groove, one end of the driving screw away from the fixed table extends out of the workbench and is connected to a handwheel, the bottom end of the middle part of the sliding table extends into the sliding groove and is connected to the driving screw, and the projection of the sliding groove toward the top surface of the workbench is orthogonal to the sliding table.

[0009] By adopting the above technical solution, the movement of the sliding platform is controlled by rotating the driving screw after the hand wheel is turned.

[0010] The utility model is further configured that the top surface of the workbench is provided with guide grooves on both sides of the sliding groove, and the sliding platform has a protrusion extending toward the inside of the guide groove.

[0011] By adopting the above technical solution, the guide groove is used to guide the sliding of the sliding table.

[0012] The utility model is further configured that the top surface of the workbench is fixedly connected to the limiting platform at a position at one end of the sliding groove away from the fixing platform.

[0013] By adopting the above technical solution, the limiting platform is used to prevent the sliding platform from sliding beyond the top surface range of the workbench.

[0014] The utility model is further configured that two sliding blocks are respectively arranged in the fixed platform and the sliding platform.

[0015] By adopting the above technical solution, a total of four sliding blocks in the fixed table and the sliding table are used to respectively fix the edges of the four legs of the workpiece.

[0016] The utility model is further configured that a first pressing piece facing the direction of the sliding platform is connected inside the sliding block in the fixed platform, and a second pressing piece facing the direction of the fixed platform is connected inside the sliding block in the sliding platform.

[0017] By adopting the above technical solution, the first pressing plate in the fixing table presses down and fixes the foot edge on one side of the workpiece, while the second pressing plate presses down and fixes the foot edge on the other side of the workpiece.

[0018] The utility model is further configured such that the edges of the first pressing sheet and the second pressing sheet are both provided with downward bends, and the length of the second pressing sheet is greater than that of the first pressing sheet.

[0019] By adopting the above technical solution, the downwardly bent portions of the edges of the first pressing plate and the second pressing plate can better press and fix the workpiece.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. The utility model slides a press table structure parallel to each other on a workbench, slides a sliding block and a friction plate that slides synchronously with the sliding block in the press table along the length direction, and when the press table on the sliding block is pressed down, the friction plate contacts the inner wall of the slider groove of the press table structure, and the pressing of the press table and the positioning of the sliding block are realized synchronously, which greatly reduces the time for tightening and loosening the bolts of the clamping structure and effectively improves the clamping speed of the clamping mechanism;

[0022] 2. The utility model arranges an extended pressing sheet structure in the sliding block on the sliding table, and moves the sliding table in the opposite direction after the pressing sheet is pressed down, so as to conveniently realize the positioning of the sliding table, so that the extended pressing sheet structure can not only realize the downward pressing in the vertical direction, but also play a certain positioning role for the workpiece in the horizontal direction.

[0029] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1

[0032] A quick clamping mechanism for mechanical manufacturing, such as Figure 1-5 As shown, it includes a workbench 1. Specifically, the top surface of the workbench 1 is a plane, which can better carry the workpiece and is conducive to the pressing of the workpiece by the pressing structure. One end of the top surface of the workbench 1 is fixedly connected to a fixed table 2, and a sliding table 3 parallel to the fixed table 2 is slidably connected to the top surface. Slider grooves 9 are arranged in the fixed table 2 and the sliding table 3 along the length direction. Specifically, the slider groove 9 is divided into an upper and lower layers, wherein a slider 10 is slidably connected in the upper layer, and a friction plate 11 is slidably connected in the lower layer. The upper layer and the lower layer do not interfere with each other, but the fastening bolts 12 can pass through the upper and lower layers of the slider groove 9. At least one slider 10 is slidably connected in the slider groove 9, and the slider 10 is penetrated by a fastening bolt 12 in the vertical direction. The bottom end of the fastening bolt 12 is sleeved with a friction plate 11, and the friction plate 11 is located below the slider 10 but does not contact the slider 10. The upper ends of the fastening bolts 12 are penetrated by the pressing structure.

[0033] See also Figure 3-5 Two sliders 10 are respectively provided in the fixed table 2 and the sliding table 3. A total of four sliders in the fixed table 2 and the sliding table 3 are used to fix the edges of the four legs of the workpiece respectively, so as to effectively and stably fix the workpiece. The slider 10 in the fixed table 2 is connected with a first pressing piece 13 facing the sliding table 3, and the slider 10 in the sliding table 3 is connected with a second pressing piece 14 facing the fixed table 2. The first pressing piece 13 in the fixed table 2 presses down and fixes the leg edge on one side of the workpiece, and the second pressing piece 14 presses down and fixes the leg edge on the other side of the workpiece. The edges of the first pressing piece 13 and the second pressing piece 14 are both provided with downward bends.

[0034] See also Figure 3-5 The length of the second pressing sheet 14 is greater than that of the first pressing sheet 13. Specifically, after the second pressing sheet 14 is pressed down, the sliding table 3 slides a short distance away from the fixed table 2, and the edge of the bottom end of the second pressing sheet 14 can contact the edge of the bottom end of the workpiece, further improving the degree of compression of the workpiece by the second pressing sheet 14. The downwardly bent portions of the edges of the first pressing sheet 13 and the second pressing sheet 14 can better compress and fix the workpiece.

[0035] Embodiment 2

[0036] A quick clamping mechanism for mechanical manufacturing, such as Figure 1-5As shown, on the basis of Example 1, the difference from Example 1 lies in that a sliding groove 5 is provided on the surface of the workbench 1, a driving screw 6 is rotatably provided in the sliding groove 5, the driving screw 6 extends out of the workbench 1 at one end away from the fixed table 2 and is connected with a handwheel 7, the bottom end of the middle part of the sliding table 3 extends into the sliding groove 5 and is connected with the driving screw 6, the projection of the sliding groove 5 toward the top surface of the workbench 1 is orthogonal to the sliding table 3, and after rotating the handwheel 7, the movement of the sliding table 3 is controlled by the rotation of the driving screw 6.

[0037] See also Figure 1-3 The top surface of the workbench 1 is provided with guide grooves 8 on both sides of the sliding groove 5. The sliding table 3 has a protrusion extending toward the guide groove 8, and the guide groove 8 is used to guide the sliding of the sliding table 3. The top surface of the workbench 1 is fixedly connected to the limit table 4 at one end of the sliding groove 5 away from the fixed table 2. Specifically, the limit table 4 is parallel to the fixed table 2 and the sliding table 3. The limit table 4 is used to prevent the sliding table 3 from sliding beyond the top surface range of the workbench 1.

[0038] The working principle of the utility model is as follows: after placing the workpiece to be clamped and fixed on the workbench 1, the workpiece is pushed so that one side is close to the fixed table 2, and the position of the slider 10 in the fixed table 2 is slidably adjusted so that the first pressing piece 13 on the slider 10 is aligned with the foot edge of the workpiece, and then the hand wheel is turned to make the sliding table 3 close to the workpiece, and the position of the slider 10 in the sliding table 3 is adjusted so that the second pressing piece 14 faces the foot edge on the other side of the workpiece, and all the fastening bolts 12 are tightened synchronously. When the fastening bolts 12 are tightened, the friction plate 11 is subjected to pressure and contacts the inner wall of the slider groove 9, which has the effect of limiting the movement of the slider 10. The first pressing piece 13 and the second pressing piece 14 simultaneously clamp the edge of the workpiece foot, and then the hand wheel 7 is slightly turned in the opposite direction to make the sliding table 3 slide away from the fixed table 2 until the edge of the bottom end of the second pressing piece 14 contacts the foot edge of the workpiece and then the hand wheel 7 is stopped, and the edge of the second pressing piece 14 is used to further clamp and fix the workpiece, so that the clamping and fixing of the workpiece can be conveniently achieved.
