Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a machining tooling, tooling table and system. Background Technology

[0002] In mold machining, many workpieces require high flatness and are typically processed using magnetic disk adsorption or clamping plates. However, due to clamping forces, the workpieces are prone to twisting and deformation after demagnetization or loosening of the clamping plates. To ensure workpiece flatness, it is usually necessary to reduce the machining cutting amount or perform repeated milling, which inevitably prolongs processing time and increases production costs.

[0003] In the prior art, in order to achieve a more reliable tooling effect, the tooling structure and the workpiece are usually in hard contact, and all tooling structures are kept consistent in order to reduce the workpiece deformation caused by tooling errors between tooling structures. This design structure causes the tooling structure to be unable to adapt to the uneven shape of the workpiece blank surface, resulting in poor flatness of the processed workpiece.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a machining tooling, tooling table and system to solve the technical problem that the tooling structure cannot adapt to the uneven shape of the workpiece blank surface, resulting in poor flatness of the machined workpiece.

[0006] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution:

[0007] In a first aspect, the present invention provides a machining tooling component, including a disk and a magnetic guide block, wherein the magnetic guide block includes a first magnetic guide block and a second magnetic guide block; the first magnetic guide block is disposed on the disk; the second magnetic guide block is connected to the first magnetic guide block through an elastic member, and the second magnetic guide block is at least able to slide away from the workpiece under the pressure of the workpiece, and the elastic member is used to push the second magnetic guide block to reset after the workpiece is removed.

[0008] In conjunction with the first aspect, the first magnetic block is provided with a first inclined surface, and the second magnetic block is provided with a second inclined surface adapted to the first inclined surface. The second magnetic block can compress the elastic element under the pressure of the workpiece, so that the second inclined surface contacts the first inclined surface and slides along the first inclined surface.

[0009] In conjunction with the first aspect, further, the magnetic conductive blocks are provided in multiples, and the multiple magnetic conductive blocks are distributed in an array on the disk.

[0010] In conjunction with the first aspect, the disk is further provided with an adjustable support column, the minimum adjustable height of which is not lower than the height of the first magnetic block, and the maximum adjustable height of which is not higher than the height of the second magnetic block in its naturally popped-up state.

[0011] In conjunction with the first aspect, the adjusting support column further includes an adjusting section and a threaded section connected to the adjusting section, and the disk is provided with a threaded hole adapted to the threaded section.

[0012] In conjunction with the first aspect, the adjustment support columns are further distributed near the edge of the disk.

[0013] Secondly, this utility model also provides a machining fixture table, including a fixture plate and the aforementioned machining fixtures; at least three machining fixtures are provided, and at least three machining fixtures are not on the same straight line; the disk of the machining fixture is fixed to the fixture plate.

[0014] In conjunction with the second aspect, the machining tooling parts are further distributed along the edge of the tooling plate, and the adjustment support columns of each machining tooling part are all arranged close to the edge of the tooling plate.

[0015] In conjunction with the second aspect, the tooling plate is further provided with machining tooling parts as described in the first aspect.

[0016] Thirdly, this utility model also provides a machining system, including the machining tooling described in any one of the first aspects.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0018] 1. The machining fixture provided in this embodiment of the utility model, when in use, the workpiece is placed on the second magnetic block, and the disk generates a magnetic field after being powered on. The magnetic field acts on the workpiece through the magnetic block, thereby generating an adsorption force on the workpiece in the direction of the disk. Since the second magnetic block is connected to the first magnetic block through an elastic element, the second magnetic block can adapt to the uneven shape of the workpiece blank surface, avoid the deformation of the workpiece caused by the machining fixture, and help improve the flatness of the workpiece.

[0019] 2. The machining fixture provided in this embodiment of the utility model has at least three machining fixtures on the fixture plate, and at least three of the machining fixtures that are not on the same straight line are equipped with adjustable support columns. The three adjustable support columns can determine three support points, thereby determining a plane. Before the workpiece is processed, the support height of the three adjustable support columns is changed to make the upper surface of the workpiece as horizontal as possible, correct the flatness of the workpiece in advance, reduce the subsequent machining allowance, save machining time, improve production efficiency, and save processing costs.

[0027] The technical solutions of the present invention 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 invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Example 1

[0028] This embodiment provides a machining tooling, such as Figure 1 As shown, the system includes a disk 1 and magnetic blocks. The magnetic blocks include a first magnetic block 2 and a second magnetic block 3. The first magnetic block 2 is connected to the disk 1, and the second magnetic block 3 is connected to the first magnetic block 2 via an elastic element (not shown in the figure). Under normal conditions, the elastic element supports the second magnetic block 3 in a naturally spring-up state. Before processing, the workpiece is placed on the second magnetic block 3 with the surface to be processed facing upwards. During processing, the magnetic field generated by the disk 1 being powered on acts on the workpiece through the magnetic block, thereby generating an attractive force on the workpiece towards the disk. From the moment the workpiece is placed on the second magnetic block 3, the uneven shape of the lower surface of the workpiece will compress the second magnetic block 3 to varying degrees, and the elastic element will be compressed to varying degrees, thus adapting the second magnetic block 3 to the shape of the lower surface of the workpiece, avoiding deformation of the workpiece caused by the processing fixture, and helping to improve the flatness of the workpiece. After the workpiece is processed, it is removed from the second magnetic block 3. At this time, the elastic element will push the second magnetic block 3 back to its naturally spring-up state.

[0029] In summary, the machining fixture provided in this embodiment of the present invention uses a disk 1 to adsorb the workpiece and sets a magnetic block between the disk 1 and the workpiece to avoid blocking the magnetic field formed after the disk 1 is powered on. The magnetic block has a split structure, and the second magnetic block 3, which is in direct contact with the workpiece, is connected to the first magnetic block 2 through an elastic element, so that the second magnetic block 3 is in a floating state and can adapt to the concave and convex shape of the lower surface of the workpiece, reducing the deformation of the workpiece during the machining process and helping to improve the workpiece yield.

[0030] In this embodiment, the connection between the first magnetic block 2 and the disk 1 can be a fixed connection or a detachable connection, and there is no limitation on this. The elastic element can be a spring, but the material of the elastic element is not limited to springs and can also be other elastic materials; in addition, the specific position of the elastic element is not limited in this embodiment, as long as it does not affect the relative sliding between the first magnetic block 2 and the second magnetic block 3.

[0031] When the second magnetic block 3 is compressed to fit against the first magnetic block 2, and further compression of the elastic element prevents the second magnetic block 3 from adapting to the lower surface of the workpiece, the second magnetic block 3 can be made to slide relative to the first magnetic block 2, thereby causing the second magnetic block 3 to slide further away from the workpiece. Therefore, as an optional implementation, the opposing surfaces of both the first magnetic block 2 and the second magnetic block 3 can be set as inclined planes, and further vertical movement can be achieved through the relative sliding of the two inclined planes. Specifically, as shown... Figures 1 to 3As shown, the first magnetic block 2 has a first inclined surface 6 facing the second magnetic block 3, and correspondingly, the second magnetic block 3 has a second inclined surface 7 facing the first magnetic block 2. The first inclined surface 6 and the second inclined surface 7 are adapted to each other, and when the two inclined surfaces are in contact, the second magnetic block 3 can continue to slide down along the first inclined surface 6 under the pressure of the workpiece, so as to avoid the second magnetic block 3 from making hard contact with the workpiece and thus prevent the workpiece from deforming.

[0032] As an optional implementation, a plurality of magnetically conductive blocks are arranged in an array on disk 1. Depending on the shape of the disk, a 3×5 rectangular array can be used, or other shapes such as circles can be used. The size of the magnetically conductive blocks can be selected according to the size of the workpiece and the surface texture. Generally speaking, the smaller and denser the magnetically conductive blocks, the better they can fit against the workpiece surface, thereby better preventing workpiece deformation. To avoid mutual interference, a certain distance is maintained between adjacent magnetically conductive blocks. Example 2

[0033] This embodiment provides a machining fixture, which differs from Embodiment 1 in that an adjusting support column 4 is also provided at the edge of the disk 1. When the workpiece is placed on the machining fixture, the adjusting support column 4 can support a certain point on the workpiece. When two machining fixtures are configured, the adjusting support columns 4 of the two machining fixtures can support two points on the workpiece, realizing leveling of the workpiece in the front-back or left-right directions. When three or more machining fixtures that are not on the same straight line are configured, the adjusting support columns 4 of at least three of the machining fixtures that are not on the same straight line can support three points on the workpiece. The three points form a plane, thereby realizing flatness adjustment of the workpiece before machining, reducing the subsequent machining allowance of the workpiece, improving machining efficiency, and reducing machining costs.

[0034] like Figure 2 As shown, in an optional embodiment, the adjusting support column 4 can be screwed into the threaded hole 10 on the disk 1 via the threaded section 9. To achieve better adjustment accuracy, the threaded section 9 can be made of fine thread with a small pitch. An adjusting section 8 is connected to one end of the threaded section 9 for easy operation to achieve the adjustment function. By rotating the adjusting section 8, the screwing length between the threaded section 9 and the threaded hole 10 is adjusted, thereby changing the support height of the adjusting support column 4.

[0035] It should be noted that the lowest adjustable height of the support column 4 should not be lower than the height of the first magnetic block 2 to prevent the second magnetic block 3 from sliding to its bottom limit position, causing the first magnetic block 2 to make hard contact with the lower surface of the workpiece, resulting in large-area deformation of the workpiece. However, the highest adjustable height of the support column 4 should not be higher than the height of the second magnetic block 3 in its naturally spring-up state, to prevent the workpiece from failing to contact the second magnetic block 3 and thus failing to utilize the floating support function of the second magnetic block 3. Specifically, as shown... Figure 3 As shown, with the upper surface of disk 1 (i.e. the mounting surface of the adjustment support column 4) as the 0 position surface, the height h1 of the adjustment support column 4 when it is installed on the 0 position surface must be greater than or equal to the height H1 of the first magnetic block 2. When rotated to the highest position, the height h2 of the adjustment support column 4 must be less than or equal to the height H2 of the second magnetic block 3 in its natural pop-up state. That is, the adjustable amount of the adjustment support column 4 is t = h2 - h1.

[0036] In this embodiment, the adjusting section 8 is a structure fixed to the upper end of the threaded section 9, and can be a nut or other planar component. Alternatively, as a variation, the adjusting section 8 can also be a cylindrical structure with internal threads and a flat top, or other planar component with adjustable height.

[0037] This embodiment of the utility model adds an adjustable support column 4, which adjusts the height of the workpiece plane to correct the flatness of the workpiece in advance and reduces the machining allowance; the three-point surface construction method ensures the flatness of the workpiece while saving machining time, improving production efficiency and saving costs; at the same time, the tooling is easy to clamp, has strong versatility, and can process a wide range of types. Example 3

[0038] This embodiment provides a machining fixture table, including a fixture plate 5. At least three machining fixtures as described in Embodiment 2 are arranged on the fixture plate 5. The adjusting support columns 4 of the three machining fixtures are not on the same straight line, thus forming a support surface. Before machining, the workpiece is supported on the aforementioned support surface, which pre-corrects the flatness of the workpiece and reduces the machining allowance.

[0039] like Figure 4 and Figure 5 As shown, as one embodiment, multiple machining fixtures as described in Embodiment 1 can also be arranged on the tooling plate 5. For ease of description, the machining fixture provided in Embodiment 1 is now described as machining fixture one, and the machining fixture provided in Embodiment 2 is described as machining fixture two. Figure 5 As shown, machining fixture one can be placed in the middle of fixture plate 5 to provide floating support according to the shape of the lower surface of the workpiece, and machining fixture two can be placed at the edge of fixture plate 5, such as... Figure 5 As shown in positions A, B, C, D, F, G, H, and J, the adjustment support columns 4 of each machining tooling part are also set close to the edge of the tooling plate 5, which is convenient for workers to adjust manually.

[0040] The following is combined with Figure 5 The following is a description of how to use the machining fixture provided in this embodiment:

[0041] S1: Select any three machining tooling parts that are not on the same straight line (such as positions A, D and G), and adjust the adjusting support column 4 at the corresponding positions to a certain height;

[0042] S2: Place the workpiece blank to be processed in the above three positions. At this time, the second magnetic block 3 in all machining tooling parts 2 is subjected to different degrees of compression depending on the condition of the lower surface of the workpiece blank.

[0043] S3: After the workpiece is stabilized, confirm the levelness of the upper surface of the workpiece blank;

[0044] S4: Based on the confirmation results, adjust the adjustment support column 4 in the above three positions to make the upper surface of the workpiece as horizontal as possible;

[0045] S5: Adjust the adjustment support column 4 of the remaining machining tooling parts 2 so that it is in contact with the workpiece but not under force;

[0046] S6: Magnetization. At this time, the disk 1 of the machining tooling is attracted to the surface of the workpiece blank through the magnetic block, fixing the workpiece so that the workpiece is not subjected to compressive or tensile stress.

[0047] S7: Machining the upper surface of the workpiece blank. After machining is completed, the disk is demagnetized and the workpiece is removed.

[0048] S8: Adjust the adjusting support column 4 in all machining tooling parts 2 to restore it to the height h1 when it is installed at position 0;

[0049] S9: Flip the workpiece and repeat the operations from S1 to S8 above to process the lower surface of the workpiece blank.

[0050] The machining fixture method provided in this embodiment can be used for rough machining of workpieces, or for fine machining of workpieces after stress treatment, depending on the flatness requirements of the drawing.

[0051] This utility model embodiment uses a plane formed by at least three adjustable support columns that are not on the same straight line to support the workpiece while adjusting the workpiece surface to be horizontal and free from stress. This allows the workpiece surface to be relatively flat after processing, reducing workpiece deformation, saving machining time, improving production efficiency, and saving costs. Example 4

[0052] Based on the machining tooling provided in Embodiment 1 and / or Embodiment 2, this embodiment provides a machining system that applies the machining tooling provided in Embodiment 1 and / or Embodiment 2 to a machining machine tool for use.

[0053] When machining fixtures as provided in Embodiment 1 and Embodiment 2 are configured simultaneously, the machining fixture table provided in Embodiment 3 can be applied as a whole to the machining machine tool. Alternatively, the machining fixtures can be directly set on the worktable of the machining machine tool. The number and position of the machining fixtures can be set according to actual machining needs and considering ease of operation.
