Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for parts processing, and specifically relates to a milling clamp side pressure clamping tool. Background Technology

[0002] When machining the first side of a rectangular aerospace part blank on a CNC machine tool, the conventional method is to first mill the blank flat in the thickness direction, then raise the blank, and then use a conventional pressure plate to press and fix the blank. After fixing, the screw holes and locating pin holes required for CNC machining are machined on the blank, and then the first side of the part is formally machined by the CNC machine tool. The whole machining process has many steps, and using a pressure plate to press the workpiece is not only slow, but also prone to loosening of the parts, which cannot meet the needs of faster and more efficient work. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a milling clamp side-pressure clamping fixture. By using side-pressure clamping to replace the conventional pressure plate fixation, the parts can be quickly clamped and the parts are not easy to loosen, thus improving work efficiency.

[0004] The objective of this utility model is achieved through the following technical solution: A milling clamp side-pressing fixture includes a fixture table. Multiple side positioning blocks are sequentially arranged along one edge of the fixture table's top surface. Multiple end positioning blocks are sequentially arranged along one end of the fixture table's top surface. Multiple side-pressing components are arranged along the other edge of the fixture table's top surface. Each side-pressing component includes a fixed block, a movable block, and an adjusting screw. The fixed block is located on the worktable. The movable blocks are located on both sides of the fixed block at the end opposite to the side positioning blocks. The adjusting screw is located on the fixed block and is used to drive the two movable blocks to slide relative to or away from each other on the top surface of the worktable. When the two movable blocks slide relative to each other, they can slide synchronously toward the side positioning blocks. When the two movable blocks move away from each other, they can slide synchronously away from the side positioning blocks.

[0005] Furthermore, the top surface of the fixing block is provided with a groove, the bottom of the groove is provided with a through hole that penetrates the fixing block, and both ends of the groove are provided with locking screws. The shank of the locking screw passes through the through hole and is threadedly connected to the workbench, and the head of the locking screw abuts against the bottom of the groove.

[0006] Furthermore, a guide block is provided at the middle of one end of the fixed block opposite to the side positioning block, two movable blocks are respectively provided on both sides of the guide block, and an adjusting screw is provided on the guide block.

[0007] Furthermore, the guide block has a strip-shaped sliding hole that runs through both sides of the guide block at one end opposite to the side positioning block along the direction toward the side positioning block. The adjusting screw passes through the strip-shaped sliding hole and the middle part of the adjusting screw is slidably connected to the strip-shaped sliding hole. The two ends of the adjusting screw are threadedly connected to the two movable blocks respectively, and the threads at the two ends of the adjusting screw are in opposite directions. The guide block has guide slopes on both sides, and the two movable blocks are slidably connected to the two guide slopes respectively.

[0008] Furthermore, the guide block and the fixing block are integrally formed.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a combination of side positioning blocks, end positioning blocks, a fixed block, movable blocks, and adjusting screws. When clamping a part, the side and end positioning blocks position the part on the fixture table. The adjusting screws then drive two movable blocks to slide relative to each other on the top surface of the worktable, simultaneously moving them towards the side positioning blocks. This causes the two movable blocks to press against the side wall of the part, securing it firmly against the side positioning blocks. When disassembling the part, the adjusting screws drive the two movable blocks to slide away from each other on the top surface of the worktable, simultaneously moving them away from the side positioning blocks until they detach from the part, releasing it and allowing for removal. Ultimately, the side-pressure assembly, in conjunction with the side positioning blocks, replaces the conventional pressure plate method with a side-pressure clamping method to achieve clamping and fixing of the part. This makes operation simpler and more reliable, enabling rapid clamping of parts, preventing loosening, and improving work efficiency. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0013] like Figure 1 , Figure 2As shown, a milling clamping side-pressing fixture includes a fixture table 1. Multiple side positioning blocks 2 are sequentially fixed along one edge of the top surface of the fixture table 1. Multiple end positioning blocks 3 are sequentially fixed along one end of the top surface of the fixture table 1. Multiple side-pressing components 4 are provided along the other edge of the top surface of the fixture table 1. When clamping a part, the part is placed on the worktable, so that the side wall of the part simultaneously abuts against the side positioning blocks 2 and the end positioning blocks 3. The side positioning blocks 2 and the end positioning blocks 3 then position the part. The side-pressing components 4 then press against the side wall of the part, pressing the part firmly against the side positioning blocks 2, thereby fixing the part and completing the clamping process.

[0014] like Figure 2 As shown, the side-pressure assembly 4 includes a fixed block 41, a movable block 42, and an adjusting screw 43. The fixed block 41 is fixed on the worktable. The movable blocks 42 are located on both sides of the fixed block 41 opposite to the side positioning block 2. The adjusting screw 43 is located on the fixed block 41. Turning the adjusting screw 43 in the forward direction can simultaneously drive the two movable blocks 42 to push against the side wall of the part, thereby pressing the part against the side positioning block 2. Turning the screw in the reverse direction can simultaneously drive the two movable blocks 42 to disengage from the part, thereby releasing the part.

[0015] like Figure 2 As shown, the top surface of the fixing block 41 is provided with a groove 5, the bottom of the groove 5 is provided with a through hole that passes through the fixing block 41, and the two ends of the groove 5 are provided with locking screws 6. The rod of the locking screw 6 passes through the through hole and is threaded to the workbench. Tighten the locking screw 6 so that the head of the locking screw 6 abuts against the bottom of the groove 5, thereby fixing the fixing block 41 on the workbench.

[0016] like Figure 2 , Figure 3 As shown, a guide block 7 is provided at the middle of one end of the fixed block 41 opposite to the side positioning block 2. The guide block 7 is integrally formed with the fixed block 41. Two movable blocks 42 are respectively provided on both sides of the guide block 7, and an adjusting screw 43 is provided on the guide block 7. More specifically, a strip-shaped sliding hole 8 is provided at one end of the guide block 7 opposite to the side positioning block 2 along the direction towards the side positioning block 2, penetrating both sides of the guide block 7. The adjusting screw 43 passes through the strip-shaped sliding hole 8, and the middle part of the adjusting screw 43 is slidably connected to the strip-shaped sliding hole 8. The two ends of the adjusting screw 43 are respectively threadedly connected to the two movable blocks 42, and the threads at the two ends of the adjusting screw 43 are opposite in direction. Guide slopes 9 are provided on both sides of the guide block 7, and the two movable blocks 42 are slidably connected to the two guide slopes 9 respectively.

[0017] After positioning the part on the tooling table 1, turn the adjusting screw 43 forward. Under the guidance and constraint of the guide slope 9, the two movable blocks 42 will slide relative to each other on the top surface of the worktable. At the same time, the two movable blocks 42, together with the adjusting screw 43, will slide synchronously toward the side positioning block 2, thereby causing the two movable blocks 42 to push against the side wall of the part and press the part tightly against the side positioning block 2. Turn the adjusting screw 43 in the opposite direction. Under the guidance and constraint of the guide slope 9, the two movable blocks 42 will slide away from each other on the top surface of the worktable. At the same time, the two movable blocks 42, together with the adjusting screw 43, will slide synchronously away from the side positioning block 2 until the two movable blocks 42 disengage from the part and the part is released, and then the part can be removed.

[0018] Based on the above-mentioned milling clamp side-pressure clamping fixture, this utility model uses the side-pressure component 4 in conjunction with the side positioning block 2 to replace the conventional pressure plate fixing method with side-pressure clamping to achieve the clamping and fixing of the parts. The operation is simpler and more reliable, and the parts can be clamped quickly. The parts are not easy to loosen, which improves work efficiency. After the parts are clamped, the screw holes and positioning pin holes required for CNC machining of the parts, as well as the first surface of the parts, can be directly machined.

[0019] Finally, although embodiments of the present invention have been shown and described above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
