Description

A support fixture for drilling and milling thin steel Technical Field

[0001] This utility model relates to the field of drilling and milling technology, specifically a support fixture for drilling and milling thin steel. Background Technology

[0002] In thin steel drilling and milling, due to the poor rigidity of the material, its easy deformation and vibration, the core function of the support fixture is to provide stable support, reduce deformation and suppress vibration.

[0003] In existing technology, milling machine worktables are equipped with support blocks for thin steel milling and the thin steel is clamped and fixed on the support blocks by a clamping device. However, most of the fixtures used on milling machine worktables today use screws to drive the movement of the clamping plate to clamp and fix the thin steel. Each time the workpiece is clamped and removed, the operator needs to manually rotate the screw to adjust the position of the clamping plate. After processing, the screws need to be rotated in the opposite direction to release the workpiece. This frequent turning operation significantly reduces production efficiency and increases the labor intensity of workers during batch processing. Summary of the Invention

[0004] The purpose of this utility model is to provide a support fixture for drilling and milling thin steel, in order to solve the problem mentioned in the background art. In the prior art, support blocks for drilling and milling thin steel are installed on the milling machine worktable, and the thin steel is clamped and fixed on the support blocks by a clamping device. However, most of the fixtures used on the milling machine worktable nowadays use screws to drive the movement of the clamping plate to clamp and fix the thin steel. Each time the workpiece is clamped and unclamped, the operator needs to manually rotate the screw to adjust the position of the clamping plate. After the processing is completed, it is necessary to rotate it in the opposite direction to release the workpiece. In batch processing, the frequent turning operations significantly reduce production efficiency and increase the labor intensity of workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support fixture for drilling and milling thin steel, comprising a base and a clamping part:

[0006] The base has a support frame on top for supporting the thin steel. The clamping part is slidably disposed on the top of the base for clamping and fixing the thin steel. The clamping part has a slider slidably disposed on the top of the base. A connecting block is rotatably disposed horizontally on the top of the slider. A rotating frame is rotatably disposed vertically on the top of the connecting block. A locking structure is disposed at the bottom of the rotating frame for limiting the rotation of the rotating frame. A screw is rotatably disposed inside the rotating frame. A pressure plate is rotatably disposed at the bottom of the screw. The pressure plate is slidably connected to the rotating frame. The rotation of the screw controls the pressure plate to descend and clamp and fix the thin steel. The rotation of the rotating frame allows the thin steel to be released quickly.

[0007] By adopting the above technical solution, it is possible to quickly clamp and release thin steel. The rotating motion of the rotating frame drives the pressure plate to quickly detach from the workpiece, avoiding the need for the traditional screw to rotate in the opposite direction for multiple turns, which significantly improves disassembly efficiency. At the same time, the threaded engagement between the screw and the threaded groove can still provide stable clamping force, ensuring the rigid fixation of the thin steel during processing and preventing vibration or deformation.

[0008] Preferably, the base has several T-slots on the top of the base, and the slider is embedded in the T-slots and slidably connected to the base.

[0009] By adopting the above technical solution, the clamping part can be flexibly positioned on the base. The cooperation between the T-slot and the slider not only ensures the linear sliding accuracy of the clamping part, but also locks and fixes the slider with bolts.

[0010] Preferably, the clamping part also has a rotating groove a formed on the top of the slider, and a rotating head is provided at the bottom of the connecting block. The rotating head is embedded in the rotating groove a and rotates to connect with the slider.

[0011] By adopting the above technical solution, the horizontal angle of the clamping part can be adjusted. The rotation of the rotating head in the rotating groove a enables the connecting block to rotate around the vertical axis, which facilitates the adjustment of the clamping direction of the pressure plate and meets the edge fixing requirements of irregular thin steel workpieces.

[0012] Preferably, the clamping part also has a limiting groove inside the connecting block, and a locking block is laterally slidably disposed inside the limiting groove. One end of the locking block is provided with a spring, which is located inside the limiting groove. A locking head is provided at the bottom of the rotating frame, and the locking block and the locking head are engaged and connected.

[0013] By adopting the above technical solution, the rotational freedom of the rotating frame can be quickly locked or released. The spring pushes the locking block to automatically engage with the chuck head, preventing the rotating frame from rotating accidentally during processing. When it is necessary to release the workpiece, simply manually move the locking block to disengage from the chuck head to unlock the rotating frame for rotation operation.

[0014] Preferably, the clamping part also has a rotating groove b provided on the top of the connecting block, and a rotating shaft is provided at the bottom of the rotating frame, which is embedded in the rotating groove b and rotatably connected to the connecting block.

[0015] By adopting the above technical solution, the longitudinal rotation of the rotating frame can be realized. Through the cooperation of the rotating shaft and the rotating groove b, the rotating frame can swing around the horizontal axis, thereby quickly lifting the pressure plate in the loosened state, avoiding interference between the pressure plate and the workpiece, and facilitating the quick handling of thin steel.

[0016] Preferably, the clamping part also has a threaded groove formed inside the rotating frame, through which the screw passes and is nested and threadedly connected to the rotating frame.

[0017] By adopting the above technical solution, the lifting and lowering of the pressure plate can be precisely controlled by rotating the screw. The rotational motion is converted into linear motion through the screw and the threaded groove, thereby controlling the movement of the pressure plate.

[0018] Preferably, the clamping part also has a groove formed inside the pressure plate, through which the rotating frame passes and is vertically slidably connected to the pressure plate.

[0019] By adopting the above technical solution, it can be ensured that the pressure plate moves only in the vertical direction. The sliding path of the rotating frame is constrained by the slide groove to prevent the pressure plate from tilting during the clamping process, ensuring that the clamping surface is parallel and in contact with the thin steel surface, and improving the clamping stability.

[0020] Preferably, the clamping part also has a rotating groove c formed on the top of the pressure plate, and the bottom of the screw is embedded in the rotating groove c and rotatably connected to the pressure plate.

[0021] By adopting the above technical solution, the torsional interference on the pressure plate when the screw rotates can be eliminated. The rotating groove c allows the bottom of the screw to rotate freely, so that the pressure plate only bears the vertical downward pressure, avoiding the pressure plate from shifting due to the rotation of the screw, and further ensuring the clamping accuracy.

[0022] Compared with the prior art, the beneficial effects of this utility model are: by setting up a clamping part, the rotating action of the rotating frame drives the pressure plate to quickly detach from the workpiece, avoiding the traditional operation of the screw needing to rotate in the opposite direction for many turns, significantly improving the disassembly efficiency. At the same time, the threaded engagement between the screw and the threaded groove can still provide a stable clamping force, ensuring the rigid fixation of the thin steel during the processing and preventing vibration or deformation.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please refer to Figures 1, 2, and 3. This embodiment provides a technical solution: a support fixture for drilling and milling thin steel, including a base 1 and a clamping part 2.

[0032] A support frame 101 is provided on the top of the base 1 to support the thin steel. A clamping part 2 is slidably disposed on the top of the base 1 to clamp and fix the thin steel. A slider 201 is slidably disposed on the top of the base 1. A connecting block 203 is rotatably disposed horizontally on the top of the slider 201. A rotating frame 209 is rotatably disposed vertically on the top of the connecting block 203. A locking structure is provided at the bottom of the rotating frame 209 to restrict the rotation of the rotating frame 209. A screw 213 is rotatably disposed inside the rotating frame 209. A pressure plate 214 is rotatably disposed at the bottom of the screw 213. 4. The screw 213 is slidably connected to the rotating frame 209. The rotation of the screw 213 controls the lowering of the pressure plate 214 to clamp and fix the thin steel. The rotation of the rotating frame 209 allows for quick clamping and loosening of the thin steel. The rotation of the rotating frame 209 drives the pressure plate 214 to quickly detach from the workpiece, avoiding the need for the screw 213 to rotate in the opposite direction multiple times in the traditional way, which significantly improves disassembly efficiency. At the same time, the threaded engagement between the screw 213 and the threaded groove 212 can still provide a stable clamping force, ensuring the rigid fixation of the thin steel during processing and preventing vibration or deformation.

[0033] Example 2

[0034] Please refer to Figures 3, 4, and 5. This embodiment provides a technical solution: a support fixture for drilling and milling thin steel, including a clamping part 2, a connecting block 203, and a rotating frame 209.

[0035] Several T-slots 102 are horizontally opened on the top of the base 1. The slider 201 is embedded in the T-slots 102 and slidably connected to the base 1, which can realize the flexible positioning of the clamping part 2 on the base 1. The cooperation between the T-slots 102 and the slider 201 not only ensures the linear sliding accuracy of the clamping part 2, but also locks and fixes the slider 201 by bolts.

[0036] A rotating groove a202 is provided on the top of the slider 201, and a rotating head 206 is provided on the bottom of the connecting block 203. The rotating head 206 is embedded in the rotating groove a202 and rotates to connect with the slider 201, which can realize the horizontal angle adjustment of the clamping part 2. By rotating the rotating head 206 in the rotating groove a202, the connecting block 203 can rotate around the vertical axis, which is convenient to adjust the clamping direction of the pressure plate 214 and adapt to the edge fixing requirements of irregular thin steel workpieces.

[0037] A limiting groove 204 is horizontally formed inside the connecting block 203. A locking block 207 is horizontally slidably arranged inside the limiting groove 204. A spring 208 is provided at one end of the locking block 207. The spring 208 is located inside the limiting groove 204. A locking head 211 is provided at the bottom of the rotating frame 209. The locking block 207 and the locking head 211 are engaged and connected, which can quickly lock or release the rotational freedom of the rotating frame 209. The spring 208 pushes the locking block 207 to automatically engage with the locking head 211 to prevent the rotating frame 209 from rotating accidentally during processing. When it is necessary to release the workpiece, the locking block 207 only needs to be manually moved to disengage from the locking head 211 to unlock the rotating frame 209 for rotation operation.

[0038] A rotating groove b205 is provided on the top of the connecting block 203, and a rotating shaft 210 is provided at the bottom of the rotating frame 209. The rotating shaft 210 is embedded in the rotating groove b205 and rotatably connected to the connecting block 203, which can realize the longitudinal rotation of the rotating frame 209. Through the cooperation of the rotating shaft 210 and the rotating groove b205, the rotating frame 209 can swing around the horizontal axis, thereby quickly lifting the pressure plate 214 in the loosened state, avoiding interference between the pressure plate 214 and the workpiece, and facilitating the quick handling of thin steel.

[0039] A threaded groove 212 is vertically provided inside the rotating frame 209. The screw 213 passes through the threaded groove 212 and is nested and threadedly connected to the rotating frame 209. The lifting and lowering of the pressure plate 214 can be precisely controlled by rotating the screw 213. The rotational motion is converted into linear motion through the threaded transmission between the screw 213 and the threaded groove 212, thereby controlling the movement of the pressure plate 214.

[0040] A vertical groove 215 is provided inside the pressure plate 214. The rotating frame 209 passes through the groove 215 and slides vertically with the pressure plate 214. This ensures that the pressure plate 214 moves only in the vertical direction. The groove 215 constrains the sliding path of the rotating frame 209, preventing the pressure plate 214 from tilting during clamping. This ensures that the clamping surface is parallel and in contact with the thin steel surface, improving clamping stability.

[0041] A rotating groove c216 is provided on the top of the pressure plate 214. The bottom of the screw 213 is embedded in the rotating groove c216 and rotatably connected to the pressure plate 214. This can eliminate the torsional interference of the screw 213 on the pressure plate 214 when it rotates. The rotating groove c216 allows the bottom of the screw 213 to rotate freely, so that the pressure plate 214 only bears the vertical downward pressure, avoiding the offset of the pressure plate 214 due to the rotation of the screw 213, and further ensuring the clamping accuracy.

[0042] Working principle: First, the thin steel workpiece is placed on the support frame 101 of the base 1. According to the size of the workpiece, the clamping part 2 is pushed to slide along the T-slot 102 on the base 1. After adjusting the slider 201 to a suitable position, it is locked and fixed by bolts. Then, the rotating head 206 at the bottom of the connecting block 203 is rotated so that it rotates horizontally in the rotating groove a202 of the slider 201, driving the pressure plate 214 to align with the edge of the workpiece. Then, the operator manually rotates the screw 213, which moves downward through the transmission of the thread groove 212, pushing the pressure plate 214 to descend vertically along the slide groove 215 of the rotating frame 209 until the pressure plate 214 is tightly attached to the surface of the thin steel, completing the clamping. At this time, the chuck 211 at the bottom of the rotating frame 209 and the chuck in the connecting block 203 are engaged. Under the action of spring 208, 207 automatically engages, locking the rotational freedom of the rotating frame 209. After clamping, the thin steel is stably fixed between the support frame 101 and the pressure plate 214. The thread self-locking characteristic of the screw 213 ensures that the clamping force is constant, avoiding workpiece displacement or deformation caused by processing vibration. After processing, the operator manually moves the clamping block 207 to compress the spring 208, causing the chuck 211 to disengage from the clamping block 207, unlocking the rotating frame 209, and lifting the rotating frame 209 upward. The rotating shaft 210 at its bottom rotates around the horizontal axis in the rotating groove b205 of the connecting block 203, driving the pressure plate 214 to quickly lift away from the workpiece surface. Loosen the bolts of the clamping part 2, and move the entire clamping part 2 out of the workpiece area along the T-slot 102, so that the thin steel can be quickly removed.
