[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0027] Please see Figures 1-6 The present invention provides the following technical solution: Example 1, see Figure 1A dual-station adjustable adaptive side-top fixture suitable for machining thin-walled castings includes a base plate assembly 1. The top of the base plate assembly 1 is sequentially provided with a first machining station 2 and a second machining station 3. The first machining station 2 has a product to be processed 4 at the middle position, and the second machining station 3 has a product to be processed 5 at the middle position.
[0028] Among them, the base plate assembly 1 is made of high-strength metal material, which ensures the overall structural strength and rigidity of the fixture, making it less prone to deformation during processing and providing a foundation for the stable clamping of thin-walled castings. The first processing station 2 is used to limit and clamp the product to be processed 4, reducing the possibility of the product to be processed 4 shaking during processing. The first processing station 2 is adapted to the product to be processed 4, so that the product to be processed 4 can be kept stable. The second processing station 3 is used to limit and clamp the product to be processed 5, so that the product to be processed 5 can be kept stable during processing.
[0029] By setting up two sets of limiting clamping devices, namely the first processing station 2 and the second processing station 3, the first processing station 2 and the second processing station 3 can position and clamp the products to be processed 1 4 and 2 5, so that the clamping force on the products to be processed 1 4 and 2 5 is balanced, which can reduce the possibility of deformation of the products to be processed 1 4 and 2 5 during the clamping process and improve the processing accuracy of the products.
[0030] The base plate assembly 1 includes a base plate body 11, and a plurality of first limiting posts 12 and second limiting posts 13 are provided on the top of the base plate body 11.
[0031] The base plate body 11 provides installation space for the first limiting post 12 and the second limiting post 13. The first limiting post 12 is located in the middle of the first processing station 2, and the second limiting post 13 is located in the middle of the second processing station 3. The first limiting post 12 and the second limiting post 13 can respectively perform preliminary positioning of the product to be processed 4 and the product to be processed 5, thereby improving the accuracy of subsequent clamping of the product to be processed 4 and the product to be processed 5.
[0032] Both product 1 (4) and product 2 (5) are thin-walled castings.
[0033] See Figure 2 The first processing station 2 includes three sets of first fixed support seats 21 for limiting the product to be processed 4, three sets of first side top clamping blocks 22 for clamping and fixing the side of the product to be processed 4, a first floating support seat 23, and a first auxiliary support seat 24 for auxiliary support of the product to be processed 4.
[0034] See Figure 3The second processing station 3 includes three sets of second fixed support seats 31 for limiting the position of the product to be processed 5, three sets of second side top clamping blocks 32 for clamping and fixing the side of the product to be processed 5, a second floating support seat 33, and a second auxiliary support block 34 for auxiliary support of the product to be processed 5.
[0035] See Figure 2 The three sets of first fixed support seats 21 and first side top clamping blocks 22 are all set on the top of the base plate body 11, the first floating support seat 23 is set on one side of the product to be processed 4, and the first auxiliary support seat 24 is set at the corner position of the product to be processed 4.
[0036] See Figure 2 Two sets of first fixed support seats 21 are arranged on the same side, two sets of first side top clamping blocks 22 are arranged on opposite sides of the two sets of first fixed support seats 21, and the remaining set of first fixed support seats 21 is arranged opposite to the first side top clamping blocks 22.
[0037] See Figure 3 The three sets of second fixed support seats 31 and second side top clamping blocks 32 are all set on the top of the base plate body 11, the second floating support seat 33 is set on one side of the product to be processed 5, and the second auxiliary support block 34 is set at the corner position of the product to be processed 5.
[0038] See Figure 3 Two sets of second fixed support seats 31 are arranged on the same side, two sets of second side top clamping blocks 32 are arranged on opposite sides of the two sets of second fixed support seats 31, and the remaining set of second fixed support seats 31 is arranged opposite to the second side top clamping blocks 32.
[0039] Among them, the structure of the three sets of first fixed support seats 21 is consistent with the structure and function of the three sets of second fixed support seats 31. The first fixed support seat 21 includes a base and a positioning column. The base is fixedly installed on the top of the base plate body 11, and the positioning column is installed on the base. The positioning column includes a mounting groove and a positioning element. The positioning element is installed inside the mounting groove and is hinged to the mounting groove. The positioning element can move in the mounting groove. That is, when the positioning element contacts the side of the workpiece, the second processing station 3 can adjust its angle according to the workpiece position to adapt to the workpiece. The end face of the positioning element is provided with a contact surface. By setting the contact surface, the first fixed support seat 21 can better contact the workpiece, increasing the positioning accuracy and clamping stability.
[0040] The structures of the three sets of first side top clamping blocks 22 are the same as those of the three sets of second side top clamping blocks 32, the structures of the first floating support seat 23 and the second floating support seat 33 are the same, and the structures of the first auxiliary support seat 24 and the second auxiliary support block 34 are the same. In the specific clamping process, their usage and function are the same.
[0041] In this embodiment, the first processing station 2 is a roughing station and the second processing station 3 is a finishing station. In actual use, the order of roughing and finishing can be changed.
[0042] Specifically, firstly, the thin-walled casting is placed at the first processing station 2. When the casting is placed at the first processing station 2, the three sets of first fixed support seats 21 and the first limiting column 12 can initially position the casting. Then, the first floating support seat 23 is adjusted to fit against the side wall of the casting, and then the three sets of first side top clamping blocks 22 are adjusted to fix and clamp it. At the same time, the first auxiliary support seat 24 provides auxiliary support for the corner of the casting. After the casting is clamped, the processing device is started to perform preliminary rough processing.
[0043] After the initial rough machining is completed, the casting is moved to the second machining station 3 and clamped there. Once the casting is clamped again, the finishing machining can continue.
[0044] See Figure 4 The first side top clamping block 22 includes a first fixed base 221, and a first adjusting block 222 is provided on one side of the first fixed base 221. The first fixed base 221 and the first adjusting block 222 are slidably connected.
[0045] See Figure 5 A first sliding block 223 is provided on the side of the first adjusting block 222 away from the first fixed seat 221, and a first support column 224 is provided on the side of the first sliding block 223 away from the first adjusting block 222. The first support column 224 is used to limit and fix the product to be processed.
[0046] The first fixed seat 221 has a guide groove on its side wall. The first adjusting block 222 is connected to the guide groove via a slider. The slider can slide along the guide groove, that is, the first adjusting block 222 is slidably connected to the first fixed seat 221. The first fixed seat 221 is also provided with a threaded hole. The first adjusting block 222 is provided with a bolt. The bolt engages with the threaded hole. When the bolt on the first adjusting block 222 is turned, the axial rotational force of the bolt is converted into the linear movement of the first adjusting block 222 along the guide groove on the first fixed seat 221.
[0047] The first adjusting block 222 and the first sliding block 223 are engaged by inclined surfaces. When the first adjusting block 222 moves along the first fixed seat 221, its inclined surface pushes the inclined surface of the first sliding block 223, decomposing the axial movement of the first adjusting block 222 into the horizontal lateral movement of the first sliding block 223, so that the first sliding block 223 moves closer to the workpiece, and finally achieves lateral clamping.
[0048] The end face of the first support column 224 is provided with a mounting groove, and a positioning element is provided inside the mounting groove. The positioning element is hinged to the mounting groove and can move within the mounting groove. That is, when the positioning element contacts the side of the workpiece, its angle can be adjusted according to the workpiece position to adapt to the workpiece. The end face of the positioning element is provided with a contact surface. By providing a contact surface, the first side top clamping block 22 can better contact the workpiece, thereby increasing the accuracy of positioning and the stability of clamping.
[0049] The first floating support 23 includes a first mounting base 231, a first floating adjustment column 232 is provided through the first mounting base 231, a first fixing nut 233 is sleeved on the outside of the first floating adjustment column 232, and the first floating adjustment column 232 can move laterally along the first mounting base 231.
[0050] The first mounting base 231 can be fixedly installed on the top of the base plate body 11. The first floating adjustment column 232 can move laterally along the first mounting base 231. By setting the first floating adjustment column 232 to move laterally along the first mounting base 231, it can adapt to castings of different sizes, making it easier to limit and clamp the castings more stably. After the position of the first floating adjustment column 232 is adjusted, the first floating adjustment column 232 can be fixed by the first fixing nut 233 to further strengthen the clamping. The end face of the first floating adjustment column 232 is provided with a mounting groove. The mounting groove is provided with a positioning element, and the positioning element is hinged to the mounting groove. The positioning element can move in the mounting groove. That is, when the positioning element contacts the side of the workpiece, its angle can be adjusted according to the workpiece position to adapt to the workpiece. The end face of the positioning element is provided with a contact surface. By setting the contact surface, the first floating support 23 can better contact the workpiece, increasing the positioning accuracy and clamping stability.
[0051] See Figure 6 The first auxiliary support base 24 includes a first fixing block 241, and a first auxiliary support block 242 is provided on one side of the first fixing block 241. The first auxiliary support block 242 and the first fixing block 241 are integrally formed. A V-shaped adapter groove is provided on the first auxiliary support block 242, and a chamfer is provided inside the V-shaped adapter groove.
[0052] The first auxiliary support block 242 is configured with a V-shaped structure and has a chamfer inside. The V-shaped structure and chamfer can be adapted to castings of various sizes, and can provide more stable auxiliary support for the castings to meet the requirements for clamping the castings.
[0053] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
