[0002] A milling fixture is a fixing device used to fix a workpiece or tool during milling, ensuring that the workpiece remains stable and does not shift or deform during processing. It is a common fixture used for fixing stainless steel parts during milling and is quite common in the existing technology.

[0003] Existing technologies, such as the utility model patent with publication number CN210451867U, disclose a fixture for milling ship parts. This patent employs a fixed base, a transmission assembly, a clamping block, and a bracket. The fixture is mounted on a machine tool spindle or machining platform. The transmission assembly connects the fixed base and the clamping block, driving the clamping block to perform linear motion relative to the fixed base.

This fixture is easy to operate and clamp, shortens clamping time, has low manufacturing costs, effectively improves the efficiency of milling operations, and ensures machining accuracy.

[0004] The inventors discovered in the prior art that when personnel are clamping and fixing various complex stainless steel parts, traditional milling fixtures can only clamp the surface of the stainless steel parts. When the surface of the stainless steel parts is not suitable for clamping, personnel have to replace the original milling fixture. Moreover, the replacement process is very time-consuming, which leads to low work efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the traditional milling fixture in the prior art can only clamp the surface of the stainless steel part body. When the surface of the stainless steel part is not suitable for clamping, the personnel can only replace the original milling fixture. Moreover, the replacement process is very time-consuming, which leads to low work efficiency. Therefore, a new type of milling fixture for stainless steel parts is proposed.

Three guide grooves are formed on the inner wall of the turntable. A movable column is movably connected to the inner wall of each guide groove. A top plate is fixedly connected to the upper end of the fixing column. Three connecting grooves are formed on the inner wall of the top plate. A connecting rod is fixedly connected to the inner wall of each connecting groove. A connecting plate is slidably connected to the arc surface of each connecting rod. The connecting plate is rotatably connected to the movable column. A rotating block is rotatably connected to the surface of the turntable. The lower surface of the top plate...

The positioning block is slidably connected to the auxiliary groove. Two springs are provided between the upper surface of the moving plate and the limit groove. The two ends of the springs are fixedly connected to the limit groove and the moving plate, respectively. A pressing plate is fixedly connected to the side of each of the three auxiliary plates that are close to each other. The top plate is fixedly connected to the fixing frame.

[0007] The aforementioned components achieve the following effects: When milling stainless steel parts, the operator first places the stainless steel part on the top plate, then activates the cylinder to move the three pressing plates closer to the stainless steel part until they abut against it. When the operator needs to fix the stainless steel part from the inside using the pressing plates, the operator first moves the moving plate to slide the positioning block out of the auxiliary groove, then rotates the auxiliary plate until the positioning block slides into the inner wall of another auxiliary groove. The operator then positions the three pressing plates inside the stainless steel part, and activates the cylinder to make the three pressing plates abut against the inner wall of the stainless steel part. This allows the milling fixture to clamp and fix various complex stainless steel parts, improving the applicability of the milling fixture and the operator's work efficiency.

[0010] Preferably, the inner wall of the turntable is provided with three positioning grooves, and positioning rods are slidably connected to the inner wall of the positioning grooves. The three positioning rods are fixedly connected to the top plate.

[0011] The effect achieved by the above components is that the positioning groove and positioning rod can limit the turntable and improve the stability of the turntable during rotation.

[0012] Preferably, an auxiliary block is fixedly connected to the side of the movable plate away from the extrusion plate, and the cross-section of the auxiliary block is rectangular.

[0013] The effect achieved by the above components is that the auxiliary block makes it easier for personnel to move the movable plate, thereby improving the ease of operation for personnel.

[0014] Preferably, the inner wall of the auxiliary block is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly provided on the auxiliary block.

[0015] The effect achieved by the above components is that the anti-slip groove can increase the friction between the personnel's hands and the auxiliary block, and can prevent the personnel from slipping when moving the auxiliary block.

[0016] Preferably, the movable column is a stainless steel column, and the cross-section of the movable column is circular.

The upper surface of the connecting plate 313 is rotatably connected to the positioning post 316. The inner wall of the connecting plate 313 has two auxiliary grooves 322. The arc surface of the positioning post 316 is fixedly connected to the auxiliary plate 314. The inner wall of the auxiliary plate 314 has a limit groove 317. The inner wall of the limit groove 317 is slidably connected to the moving plate 324. The lower surface of the moving plate 324 is fixedly connected to the positioning block 323. The positioning block 323 is slidably connected to the auxiliary groove 322. The upper surface of the moving plate 324 and the limit groove 317 are provided with two springs 319. The two ends of the springs 319 are fixedly connected to the limit groove 317 and the moving plate 324 respectively. The three auxiliary plates 314 are fixedly connected to the side of each other. The top plate 310 is fixedly connected to the fixed frame 1. When milling the stainless steel part body 2, the operator can first place the stainless steel part body 2 on the top plate 310, and then activate the cylinder 308 to move the three pressing plates 315 towards the stainless steel part body 2 until the pressing plates 315 abut against the stainless steel part body 2. When the operator needs to fix the stainless steel part body 2 from the inside of the pressing plates 315, the operator can first move the moving plate 324 to make the positioning block 323 slide out of the auxiliary groove 322, and then rotate the auxiliary plate 314 until the positioning block 323 slides out of the auxiliary groove 322. 23 slides into the inner wall of another auxiliary groove 322, and then the personnel place the three extrusion plates 315 inside the stainless steel part body 2. At this time, the personnel use the start cylinder 308 to make the three extrusion plates 315 abut against the inner wall of the stainless steel part body 2, so that the milling fixture can clamp and fix various complex stainless steel part bodies 2, improving the applicability of the milling fixture and the work efficiency of the personnel. The inner wall of the limiting groove 317 is fixedly connected to two limiting rods 318, and the spring 319 is sleeved on the arc surface of the limiting rods 318. The two limiting rods 318 are slidably connected to the moving plate 324.The limiting rod 318 can limit the spring 319, preventing deformation of the spring 319 during short-term use. The inner wall of the turntable 302 has three positioning grooves 305, and positioning rods 306 are slidably connected to the inner wall of each positioning groove 305. The three positioning rods 306 are fixedly connected to the top plate 310. The positioning grooves 305 and positioning rods 306 can limit the turntable 302, improving its stability during rotation. An auxiliary block 320 is fixedly connected to the side of the moving plate 324 away from the pressing plate 315. The auxiliary block 320 has a rectangular cross-section. The auxiliary block 320 facilitates the movement of the moving plate 324, improving operational convenience. The inner wall of the auxiliary block 320 has several anti-slip grooves 321, evenly distributed on the auxiliary block 320. The anti-slip groove 321 increases the friction between the operator's hand and the auxiliary block 320, preventing slippage during movement. The moving column 304 is made of stainless steel with a circular cross-section. The stainless steel column has high strength and good wear resistance, preventing deformation during short-term use.

[0029] The working principle of the stainless steel parts milling fixture provided by this utility model is as follows: When the stainless steel parts body 2 needs to be milled, the stainless steel parts body 2 is placed on the upper surface of the top plate 310, so that the stainless steel parts body 2 is located on the side where the three extrusion plates 315 are close to each other. Then, the operator starts the cylinder 308. The output end of the cylinder 308 drives the rotating block 307 to move away from the cylinder 308. During the process of the rotating block 307 moving away from the cylinder 308, both the cylinder 308 and the rotating block 307 will rotate. Then, the rotating block 307 drives the turntable 302 to rotate. The guide groove 303 inside the turntable 302 drives the moving column 304 to move. At this time, the positioning rod 306 is in the positioning groove. The inner wall of 305 slides, where the positioning rod 306 and positioning groove 305 can limit the turntable 302, which can improve the stability of the turntable 302 during rotation. Then, the moving column 304 drives the connecting plate 313 to move closer to the stainless steel part body 2. The connecting plate 313 drives the positioning column 316 and positioning block 323 to move closer to the stainless steel part body 2. The positioning column 316 drives the auxiliary plate 314 to move closer to the stainless steel part body 2. The auxiliary plate 314 drives the extrusion plate 315, the two limiting rods 318, the two springs 319 and the moving plate 324 to move closer to the stainless steel part body 2, until the three extrusion plates 315 are in contact with the stainless steel part. The surfaces of the stainless steel part body 2 abut against each other. If personnel find that the surface of the stainless steel part body 2 is inconvenient to fix, they can first use the auxiliary block 320 to move the moving plate 324 upwards. The auxiliary block 320 facilitates the movement of the moving plate 324, improving operational convenience. Then, the moving plate 324 moves the positioning block 323 away from the auxiliary groove 322. The moving plate 324 also causes two springs 319 to retract. The limiting rod 318 on the inner wall of the limiting groove 317 limits the springs 319, preventing deformation during short-term use, until the positioning block 323 slides out of the inner wall of the auxiliary groove 322. Then, personnel can then... Plate 314 rotates, causing the auxiliary plate 314 to drive the pressing plate 315 and the moving plate 324 to rotate until the positioning block 323 corresponds to another auxiliary groove 322. Then, the operator releases the auxiliary block 320, at which point the two springs 319 rebound, causing the positioning block 323 to move closer to the auxiliary groove 322 until the positioning block 323 slides into the inner wall of the auxiliary groove 322. Then, the operator moves the stainless steel part body 2 so that it covers the three pressing plates 315 and the three auxiliary plates 314. Then, the operator starts the cylinder 308 again, causing the rotating block 307 to move in the opposite direction closer to the cylinder 308 until the three pressing plates 315 abut against the inner wall of the stainless steel part body 2.The anti-slip groove 321 on the inner wall of the auxiliary block 320 increases the friction between the user's hand and the auxiliary block 320, preventing slippage during movement. The moving column 304 is made of stainless steel, which has high strength and good wear resistance, preventing deformation during short-term use.
