The utility model can be used for fixed side milling of regular or irregular workpieces with higher efficiency.

[0004] The inventor found in daily use that one type of five-axis impeller is an integral impeller processed by a five-axis machining center. When side milling the five-axis impeller, due to the special shape of the five-axis impeller, a special side milling fixture is required to clamp the five-axis impeller. However, when clamping the five-axis impeller with the special fixture, it was found that because the five-axis impeller is placed manually in the side milling fixture by workers, angle deviation is inevitable during placement. However, the angle deviation will cause the side milling fixture to loosen when clamping the five-axis impeller, resulting in unstable clamping, which will affect the side milling effect of the five-axis impeller, resulting in the need to adjust the clamping angle of the five-axis impeller twice or even multiple times to find a stable angle for clamping the five-axis impeller. Frequent searches for the clamping angle of the side milling fixture for the five-axis impeller will waste a lot of time, thus affecting the efficiency of side milling of the five-axis impeller. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that because the five-axis impeller is placed manually in the special fixture for side milling by workers, angle deviation is inevitable during placement, but the angle deviation will cause the special fixture for side milling to loosen when clamping the five-axis impeller, resulting in unstable clamping, which will affect the side milling effect of the five-axis impeller, resulting in the need to adjust the clamping angle of the five-axis impeller twice or even multiple times to find a stable angle for clamping the five-axis impeller, and frequently searching for the clamping angle of the five-axis impeller by the side milling fixture will waste much time, thereby affecting the efficiency of side milling of the five-axis impeller. A special fixture for five-axis side milling of an integral impeller is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises a bottom plate, a squeezing device is installed at one end of the upper surface of the bottom plate, a fixed clamp is installed on the side of the bottom plate close to the squeezing device, a movable clamp is installed on the side of the fixed clamp close to the squeezing device, an adjusting device is provided on the side where the fixed clamp and the movable clamp are close to each other, the adjusting device comprises a fixed frame, the fixed frame is fixedly connected to the fixed clamp, two first springs are fixedly connected to one side of the inner wall of the fixed frame, the two first springs are fixedly connected to the same adjusting plate on the side away from the fixed frame, an anti-skid pad is slidably connected to one side of the adjusting plate, a moving block is slidably connected to the inner wall of the anti-skid pad, a connecting rod is slidably penetrated through the inner wall of the moving block, one end of the connecting rod is fixedly connected to the fixed frame, a rotating ring is threadedly connected to the other end of the connecting rod, a slot is provided on the side of the anti-skid pad away from the adjusting plate, the inner wall of the slot is fixedly connected to the limiting frame, the inner wall of the limiting frame is slidably connected to a contact plate, and the contact plate is fixedly connected to the side wall of the fixed frame.

[0007] The effects achieved by the above components are: one type of five-axis impeller is an integral impeller processed by a five-axis machining center.

[0015] The effect achieved by the above-mentioned components is: when the base plate is placed on the workbench, the auxiliary device can be used to improve the connection stability between the base plate and the workbench, thereby avoiding the side milling fixture moving on the work plate when passing through the special fixture for side milling of the five-axis impeller, thereby affecting the stability of the side milling of the five-axis impeller.

[0016] Preferably, a plurality of contact blocks are fixedly connected to one side of the two power plates close to each other, and the plurality of contact blocks are evenly distributed on the power plates.

[0017] The effect achieved by the above components is that when the power plate contacts the workbench, the contact block installed on the power plate can increase the friction between the power plate and the workbench, thereby improving the contact stability between the power plate and the workbench through the contact block.

[0018] Preferably, an auxiliary groove is provided on one side of the support plate close to the power plate, and the elastic sheet is snap-connected with the auxiliary groove.

[0019] The effect achieved by the above components is that when the elastic sheet contacts the support plate, the auxiliary groove installed on the support plate can improve the stability of the connection between the support plate and the elastic sheet, and improve the clamping effect between the two.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0033] Reference Figure 1 - Figure 8As shown, the utility model provides a technical solution: a special fixture for five-axis side milling of an integral impeller, comprising a base plate 1, an extrusion device 4 is installed at one end of the upper surface of the base plate 1, a fixed clamp 6 is installed on the side of the base plate 1 close to the extrusion device 4, a movable clamp 5 is installed on the side of the fixed clamp 6 close to the extrusion device 4, an adjustment device 2 is provided on the side where the fixed clamp 6 and the movable clamp 5 are close to each other, and an auxiliary device 3 is provided on the side of the base plate 1.

[0034] The specific settings and functions of the adjustment device 2 and the auxiliary device 3 are described in detail below.

[0035] Reference Figure 2 - Figure 6As shown, in this embodiment: the adjustment device 2 includes a fixed frame 201, the fixed frame 201 is fixedly connected to the fixed clamp 6, one side of the inner wall of the fixed frame 201 is fixedly connected to two first springs 202, the two first springs 202 are fixedly connected to the same adjustment plate 203 on the side away from the fixed frame 201, one side of the adjustment plate 203 is slidably connected to an anti-skid pad 204, the inner wall of the anti-skid pad 204 is slidably connected to a moving block 206, the inner wall of the moving block 206 is slidably penetrated by a connecting rod 205, one end of the connecting rod 205 is fixedly connected to the fixed frame 201, the other end of the connecting rod 205 is threadedly connected to a rotating ring 207, a slot 208 is provided on the side of the anti-skid pad 204 away from the adjusting plate 203, the slot 208 The inner wall is fixedly connected to the limit frame 209, and the inner wall of the limit frame 209 is slidably connected with a contact plate 210. The contact plate 210 is fixedly connected to the side wall of the fixed frame 201. A five-axis impeller is an integral impeller processed by a five-axis machining center. When the five-axis impeller is side milled, because the shape of the five-axis impeller is relatively special, the ordinary side milling fixture for the five-axis impeller cannot be used. When the five-axis impeller needs to be side milled, a special side milling fixture for the five-axis impeller is required to clamp the five-axis impeller. Place the bottom plate 1 on the workbench, and then place the five-axis impeller between the moving clamp 5 and the fixed clamp 6, and then rotate the extrusion device 4 installed on the bottom plate 1. The rotation of the extrusion device 4 will drive the moving clamp 5 to move in the direction of the fixed clamp 6. Therefore, the five-axis impeller can be clamped and side milling can be performed on the five-axis impeller. However, when the five-axis impeller is clamped by the special fixture for side milling, when the five-axis impeller is placed in the special fixture for side milling and the angle is offset, it will cause the five-axis impeller to become loose when clamped by the special fixture for side milling. Unstable clamping will affect the side milling effect of the five-axis impeller, resulting in the need to clamp the five-axis impeller twice or even multiple times to find a stable angle for clamping the five-axis impeller. Frequent searches for the clamping angle of the five-axis impeller with the side milling fixture will waste much time and affect the efficiency of side milling of the five-axis impeller. At this time, the stability of the clamping of the five-axis impeller by the special fixture for side milling can be increased by adjusting device 2. Even if there is an error when clamping the five-axis impeller Deviation, the five-axis impeller can still be well clamped in the side milling special fixture, the inner wall of the first spring 202 is slidably connected with a telescopic rod 211, and the two ends of the telescopic rod 211 are respectively fixedly connected to the fixed frame 201 and the adjusting plate 203. When the first spring 202 drives the adjusting plate 203 to move, the telescopic rod 211 installed inside the first spring 202 can limit the movement of the first spring 202, so that the telescopic rod 211 can be used to prevent the first spring 202 from deforming when driving the adjusting plate 203 to move. The arc surface of the rotating ring 207 is provided with a plurality of connecting grooves 212, and the plurality of connecting grooves 212 are evenly distributed on the arc surface of the rotating ring 207. When the rotating ring 207 is rotated on the connecting rod 205,The connection groove 212 provided on the rotating ring 207 can increase the friction between the hand and the rotating ring 207, so that the speed of rotating the rotating ring 207 on the connecting rod 205 can be increased through the connection groove 212. A protrusion 213 is fixedly connected to the side of the contact plate 210 close to the limit frame 209. The cross section of the protrusion 213 is arc-shaped. When the contact plate 210 needs to be connected to the inner wall of the limit frame 209, the protrusion 213 installed on the contact plate 210 can increase the connection speed between the contact plate 210 and the limit frame 209, thereby improving the connection efficiency between the two.

[0036] Reference Figure 7 and Figure 8 As shown, in this embodiment: the auxiliary device 3 includes two support plates 31, and the two support plates 31 are fixedly connected to the two ends of the base plate 1 respectively, and an adjusting rod 32 is slidably penetrated through the inner wall of the base plate 1, one end of the adjusting rod 32 is fixedly connected to a power plate 33, and a clamping plate 34 is fixedly connected to the side of the power plate 33 away from the base plate 1, and an elastic sheet 36 is fixedly connected to the end of the adjusting rod 32 away from the power plate 33, and a second spring 35 is sleeved on the arc surface of the adjusting rod 32, and the two ends of the second spring 35 are fixedly connected to the adjusting rod 32 and the support plates 31 respectively. When the base plate 1 is placed on the workbench, the auxiliary device 3 can be used to improve the connection stability between the base plate 1 and the workbench, so as to avoid the side milling fixture of the five-axis impeller from being stuck on the work plate. The movement of the two power plates 33 affects the stability of the side milling of the five-axis impeller. The sides of the two power plates 33 close to each other are fixedly connected with a plurality of contact blocks 37, and the plurality of contact blocks 37 are evenly distributed on the power plate 33. When the power plate 33 contacts the workbench, the contact blocks 37 installed on the power plate 33 can increase the friction between the power plate 33 and the workbench, so that the contact stability between the power plate 33 and the workbench can be improved by the contact blocks 37. An auxiliary groove 38 is provided on the side of the support plate 31 close to the power plate 33, and the elastic sheet 36 is clamped with the auxiliary groove 38. When the elastic sheet 36 contacts the support plate 31, the auxiliary groove 38 installed on the support plate 31 can improve the stability of the connection between the support plate 31 and the elastic sheet 36, and improve the clamping effect between the two.

[0037] Detailed description of usage: When clamping the five-axis impeller with a special fixture for side milling, press the adjustment plate 203 in the direction close to the first spring 202. When pressing the adjustment plate 203, the adjustment plate 203 will drive the spring to reel up. At this time, the anti-skid pad 204 can be placed on one side of the adjustment plate 203, and the slot 208 opened on the anti-skid pad 204 and the limit frame 209 installed in the slot 208 are aligned with the contact plate 210 installed on the fixed frame 201. The adjustment plate 203 can be released. The adjustment plate 203 contacts the pressing force, and the reset of the first spring 202 will drive the adjustment plate 203 and the friction pad to approach. One side of the contact plate 210 moves, so that under the action of the first spring 202, the contact plate 210 can be driven to connect with the limit frame 209. At this time, the anti-slip pad 204 can be temporarily fixed in the fixed frame 201, and the moving block 206 is pressed in the opposite direction of the inner wall of the anti-slip pad 204 through the connecting rod 205 until the moving block 206 is pressed into the inside of the anti-slip pad 204, and then the rotating ring 207 is rotated on the connecting rod 205, so that the moving block 206 can be fixed in the anti-slip pad 204 through the connection between the rotating ring 207 and the connecting rod 205, so that the anti-slip pad 204 can be fixed in the fixed frame 201.

[0038] When the contact stability between the side milling fixture and the workbench needs to be increased, the elastic sheet 36 is stretched in the direction away from the power plate 33. When the elastic sheet 36 moves, it drives the adjustment rod 32 to slide in the support plate 31, thereby driving the second spring 35 to stretch. At this time, the side milling fixture is placed on the workbench together with the moving plate. At this time, the elastic sheet 36 can be released. The second spring 35 is rolled up to drive the adjustment rod 32 to slide in the support plate 31, so that the power plate 33 and the clamping plate 33 can be mobilized by sliding the adjustment rod 32 in the support plate 31. 4 is moved, so that the clamping plate 34 can be driven to move by the moving plate, so that the clamping plate 34 can come into contact with the side of the workbench, so that the clamping plate 34 can come into contact with the workbench, and the side milling special clamp can be temporarily restricted on the workbench. At this time, the elastic sheet 36 is pressed downward, and the pressing will inevitably cause the elastic sheet 36 to deform, and the deformed elastic sheet 36 is clamped with the support plate 31 in the direction close to the workbench, so that the elastic sheet 36 can come into contact with the support plate 31 to limit the position of the adjusting rod 32, thereby improving the contact stability between the clamping plate 34 and the workbench.
