Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and more specifically, to an adjustable fixing device for opening holes in plate-shaped workpieces. Background Technology

[0002] Plate-shaped workpieces are a common type of processing object in industrial production. They are typically planar in shape, with a relatively regular overall structure and thinness, while their length and width vary depending on the application and process requirements. Before being put into use or installed, these workpieces often require a series of pre-processing steps to ensure they meet the various requirements of subsequent use or installation. These pre-processing steps typically include grinding, polishing, and drilling. Through these meticulous processing steps, plate-shaped workpieces can better adapt to different usage environments and installation requirements.

[0003] A search revealed Chinese Patent Utility Model No. 202323208587.9, which discloses a clamping fixture for plate-shaped workpieces. The fixture includes a base plate with a recessed platform in the center to accommodate the plate-shaped workpiece. The platform has upward-protruding limiting strips at its front and rear ends, designated as a front and rear limiting strip, respectively. Bidirectional clamps are located at the center of both ends of the platform, and a pushing block is located at either the front or rear end. This utility model provides good clamping stability during workpiece processing. Limiting devices are located around the workpiece in the front-back and left-right directions. The workpiece is fixed to the base plate by bolts through tension bolt holes in the center, facilitating product processing and preventing deformation, thus significantly improving processing accuracy. However, this patent is only suitable for clamping plate-shaped workpieces with relatively straight and regular edges. It cannot stably clamp irregularly shaped workpieces. Furthermore, after clamping, the bottom of the workpiece tends to adhere to the base plate, making it easy for the drill bit to penetrate the base plate during drilling, causing wear or breakage. Therefore, this utility model proposes a new solution. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of the above-mentioned patent, which can only clamp some plate-shaped workpieces with relatively straight and regular edges, and cannot stably clamp irregularly shaped workpieces. Moreover, after the workpiece is clamped, its bottom will stick to the base plate, and the drill bit will easily drill into the base plate when drilling, causing the drill bit to wear or break. Therefore, an adjustable fixing device for opening holes in plate-shaped workpieces is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustable fixing device is used for opening holes in plate-shaped workpieces to improve the above-mentioned problems.

[0007] The present invention is as follows:

[0008] The device includes a base plate, on the top of which is a support frame. The inner side of the support frame is provided with a fixing assembly for clamping workpieces. The fixing assembly includes a support ring, multiple fixed rods, and multiple movable rods. The support ring is fixedly installed at the center of the inner side of the support frame by multiple fixed rods. The movable rods are rotatably connected to the support ring by connectors. Pneumatic limiting mechanisms are installed on both the fixed rods and the movable rods.

[0009] As a preferred technical solution of this utility model, the top of the base plate is provided with a sliding groove, and a tray located below the raised frame is slidably installed on the inner side of the sliding groove. A handle is fixedly installed on the front of the tray, and a plurality of workbench connection holes are provided on the base plate respectively located on both sides of the raised frame.

[0010] As a preferred technical solution of this utility model, both the fixed rod and the movable rod are provided with a plurality of evenly distributed adjustment screw holes.

[0011] As a preferred technical solution of this utility model, the bottom of the pneumatic limiting mechanism is connected to a first mounting plate, and the first mounting plate is threaded with an adjusting screw that cooperates with the adjusting screw hole.

[0012] As a preferred technical solution of this utility model, the pneumatic limiting mechanism includes a cylinder fixedly installed on the top of the first mounting plate, a second mounting plate fixedly connected to the moving end of the cylinder, and a wedge-shaped elastic pad fixedly connected to the second mounting plate.

[0013] As a preferred technical solution of this utility model, the connecting member includes a third mounting plate fixedly connected to the outer wall of the support ring, a threaded rod fixedly connected to the top of the third mounting plate, and a through hole that cooperates with the threaded rod through the movable rod.

[0014] As a preferred technical solution of this utility model, the outer side of the threaded rod is threaded with a nut located inside the through hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the solution of this utility model:

[0017] 1. By setting a fixed rod, a movable rod, a pneumatic limiting mechanism, and a connector, the connector allows the movable rod to rotate and adjust flexibly according to the edge shape of the workpiece during use. This facilitates precise and stable clamping of irregularly shaped workpieces at the edges through the pneumatic limiting mechanism at the top of both the fixed rod and the fixed rod. At the same time, the movable rod, which can be rotated and adjusted, can also adjust its position according to the holes on the workpiece, so that it can avoid the holes on the workpiece as much as possible. Moreover, during use, the fixed rod and the movable rod can also work with the support ring to support the bottom of the workpiece, ensuring that the workpiece remains stable during processing and does not shake or deform.

[0018] 2. By setting up a raised frame and its inner fixing components, the workpiece is suspended in mid-air when it is fixed to the inside of the raised frame. This avoids direct contact between the bottom surface of the workpiece and the base plate, effectively reducing wear and breakage caused by the drill bit hitting the base plate during drilling, and facilitating drilling operations. Simultaneously, the support ring provides support to the bottom of the workpiece while reducing contact with the workpiece surface, thus facilitating misalignment with holes on the workpiece.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] like Figures 1-5 As shown, this embodiment proposes an adjustable fixing device for drilling holes in plate-shaped workpieces, including a base plate 1, a lifting frame 2 mounted on the top of the base plate 1, and a fixing component for clamping the workpiece on the inner side of the lifting frame 2. By setting the lifting frame 2 and the fixing component on its inner side, when the workpiece is fixed to the inner side of the lifting frame 2 by the fixing component, the workpiece will be in a suspended state, avoiding direct contact between the bottom surface of the workpiece and the base plate 1. During drilling, this can effectively reduce the wear and breakage caused by the drill bit drilling into the base plate 1, making the drilling work more convenient. At the same time, the support ring 3 can also reduce the contact with the workpiece ground while providing support for the bottom of the workpiece, thereby facilitating the offset from the hole position on the workpiece. The fixing component includes a support ring 3, multiple fixing rods 8 and multiple movable rods 9. The support ring 3 is fixedly installed on the inner side of the lifting frame 2 by the multiple fixing rods 8. At the side center, the movable rod 9 is rotatably connected to the support ring 3 via the connector 11. Both the fixed rod 8 and the movable rod 9 are equipped with pneumatic limiting mechanisms 10. By setting up the fixed rod 8, the movable rod 9, the pneumatic limiting mechanisms 10, and the connector 11, the connector 11 allows the movable rod 9 to be flexibly rotated and adjusted according to the edge shape of the workpiece during use. This facilitates the precise and stable clamping of irregularly shaped workpieces at the edge by cooperating with the fixed rod 8 through the pneumatic limiting mechanisms 10 at the top of both. At the same time, the movable rod 9, which can be rotated and adjusted, can also adjust its position according to the hole position of the workpiece, so that it can avoid the hole position on the workpiece as much as possible. Moreover, during use, the fixed rod 8 and the movable rod 9 can also cooperate with the support ring 3 to support the bottom of the workpiece, ensuring that the workpiece remains stable during processing and will not shake or deform.

[0028] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a further step is to provide a groove 4 on the top of the base plate 1, and a tray 5 located below the raised frame 2 is slidably installed on the inner side of the groove 4. A handle 6 is fixedly installed on the front of the tray 5, and multiple workbench connection holes 7 are provided on the base plate 1, respectively located on both sides of the raised frame 2. It should be noted that the groove 4 facilitates the placement of the tray 5, and the tray 5 can catch falling debris and some coolant below the raised frame 2.

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in a preferred embodiment, based on the above method, both the fixed rod 8 and the movable rod 9 are further provided with multiple evenly distributed adjusting screw holes 12. The bottom of the pneumatic limiting mechanism 10 is connected to a first mounting plate 13, and the first mounting plate 13 is threaded with adjusting screws 14 that cooperate with the adjusting screw holes 12. It should be noted that during use, the position of the pneumatic limiting mechanism 10 on the fixed rod 8 and the movable rod 9 can be flexibly adjusted by adjusting the screw holes 12, the first mounting plate 13, and the adjusting screws 14, thereby facilitating the clamping of workpieces of different sizes.

[0030] like Figure 5 As shown, in a preferred embodiment, based on the above method, the pneumatic limiting mechanism 10 further includes a cylinder 101 fixedly mounted on the top of the first mounting plate 13. A second mounting plate 102 is fixedly connected to the moving end of the cylinder 101, and a wedge-shaped elastic pad 103 is fixedly connected to the second mounting plate 102. It should be noted that when in use, activating the cylinder 101 can move the second mounting plate 102 and the elastic pad 103, thereby abutting against the edge of the workpiece. The elastic pad 103 protects the edge of the workpiece.

[0031] like Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the connecting member 11 further includes a third mounting plate 111 fixedly connected to the outer wall of the support ring 3. A threaded rod 112 is fixedly connected to the top of the third mounting plate 111. A through hole 114 that mates with the threaded rod 112 is provided through the movable rod 9. A nut 113 located inside the through hole 114 is threadedly connected to the outer side of the threaded rod 112. It should be noted that in use, the movable rod 9 is installed on the outer side of the threaded rod 112 through the through hole 114, and then the nut 113 is screwed onto the threaded rod 112. When it is necessary to rotate the movable rod 9, the threaded rod 112 can be loosened. After the position of the movable rod 9 is adjusted, the nut 113 is tightened to press the movable rod 9, thereby completing the fixation of the position of the movable rod 9.

[0032] Specifically, the working principle of the adjustable fixing device for drilling plate-shaped workpieces is as follows: When in use, the base plate 1 is fixed to the worktable of the drilling equipment through the worktable connecting hole 7 and bolts. When fixing workpieces with straight and regular edges, the pneumatic limiting mechanisms 10 on multiple fixing rods 8 can cooperate with each other to complete the fixing. When drilling some irregularly shaped workpieces, the movable rod 9 is installed on the support ring 3 through the connecting piece 11, and then the position of the movable rod 9 is adjusted according to the workpiece so that the pneumatic limiting mechanism 10 on the movable rod 9 can accurately fix the edge of the workpiece, thereby making the workpiece more stable. During drilling, the tray 5 can collect the falling debris and coolant.

[0033] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
