Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In related technologies, positioning fixtures are equipped with positioning elements for positioning the workpiece. Fixtures are equipped with vacuum adsorption elements to adsorb and fix the workpiece using negative pressure, thereby preventing displacement and vibration of the workpiece during processing.

[0023] However, when the adsorption area on the workpiece is small, the vacuum adsorption component cannot provide sufficient adsorption force, resulting in uneven force on the workpiece. This can easily lead to warping or arching of the workpiece, which seriously affects the processing accuracy and product quality.

[0024] To address or improve the problem that vacuum adsorption components cannot provide sufficient adsorption force when the adsorption area on the workpiece is small, this utility model provides a positioning fixture and processing system.

[0025] The following is combined Figures 1 to 6 This describes the positioning fixture provided in the embodiments of the present invention.

[0026] Specifically, the positioning fixture has a first direction Z, a second direction X, and a third direction Y that intersect each other, for example, the first direction Z, the second direction X, and the third direction Y are perpendicular to each other.

[0027] The positioning fixture includes a material placement component 1, a mounting component 2, a suction cup 4, a positioning component 5, a drive assembly 6, and a clamping component 7.

[0028] The material placement component 1 and the mounting component 2 are spaced apart along the first direction Z and connected by a connector 3. Optionally, the connector 3 is located between the material placement component 1 and the mounting component 2, with one end of the connector 3 connected to the material placement component 1 and the other end connected to the mounting component 2. For example, the connector 3 is connected to the material placement component 1 or the mounting component 2 by means of threaded fasteners or welding.

[0029] The material placement component 1 has a bearing surface 101 for placing the workpiece 8 on the side opposite to the mounting component 2, and the bearing surface 101 has a receiving hole 102. Optionally, both the material placement component 1 and the mounting component 2 can be configured as plates, and their thickness directions are both set along the first direction Z. The mounting component 2 is used to connect to processing equipment, for example, the mounting component 2 is connected to the fixture mounting plate of the processing equipment. The processing equipment includes, but is not limited to, computer numerical control (CNC) machine tools, such as desktop CNC.

[0030] A suction cup 4 is disposed in the receiving hole 102 and is used to adsorb the workpiece 8. The suction cup 4 is a negative pressure suction cup and is used to connect to a negative pressure device to draw air out of the suction cup 4, allowing the suction cup 4 to adsorb the workpiece 8. Optionally, one end of the suction cup 4 is connected to the receiving hole 102, and the other end of the suction cup 4 protrudes from the bearing surface 101 to adsorb the workpiece 8. Optionally, the suction cup 4 is a rubber suction cup or a polyurethane suction cup.

[0031] The positioning element 5 is disposed on the material placement element 1 and is used to limit the workpiece 8 in the second direction X or the third direction Y. Optionally, the material placement element 1 is provided with corresponding positioning elements 5 in both the second direction X and the third direction Y, so as to limit the workpiece 8 in both the second direction X and the third direction Y.

[0032] The drive assembly 6 is connected to the clamping member 7. The clamping member 7 is positioned on the side of the workpiece 8 away from the placement member 1. The drive assembly 6 is mounted on the placement member 1 and is used to drive the clamping member 7 to move closer to or away from the workpiece 8 to clamp or release the workpiece 8.

[0033] In this embodiment, when using the positioning fixture, the mounting part 2 can be connected to the processing equipment so as to fix the positioning fixture to the processing equipment.

[0034] Then, the workpiece 8 is placed on the bearing surface 101 of the placement member 1. The bearing surface 101 can limit the workpiece 8 in the first direction Z. The positioning member 5 can limit the workpiece 8 in the second direction X or the third direction Y. That is, the spatial degree of freedom of the workpiece 8 can be restricted by the cooperation of the bearing surface 101 and the positioning member 5, so that the workpiece 8 has a unique and accurate position on the positioning fixture.

[0035] After the workpiece 8 is placed in place, the suction cup 4 set in the receiving hole 102 adsorbs the workpiece 8, and the driving component 6 on the material placement component 1 drives the clamping component 7 to approach the workpiece 8, which can clamp the workpiece 8. That is, the suction cup 4 and the clamping component 7 work together to fix the workpiece 8.

[0036] With this setup, the suction cup 4 and the driving component 6 drive the clamping component 7 to work together on the workpiece 8, so that the workpiece 8 fits better against the material placement component 1. The driving component 6 drives the clamping component 7 to press the workpiece 8, which can supplement the suction cup 4 to make the workpiece 8 be subjected to balanced force and avoid the problem of the workpiece 8 warping or arching due to insufficient suction force of the suction cup 4.

[0037] refer to Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the material placement member 1 is further provided with a flow channel hole 103. The flow channel hole 103 has a first orifice 1031 and a second orifice 1032. The first orifice 1031 is located at the bottom of the receiving hole 102 and is used to connect with the suction cup 4. The second orifice 1032 is located on the surface of the material placement member 1 facing the mounting member 2 and is used to connect with a negative pressure device. For example, the second orifice 1032 can be connected to the negative pressure device through a pipeline.

[0038] In this embodiment, when using the positioning fixture, the negative pressure device is connected to the second opening 1032 of the flow channel hole 103. Under the action of the negative pressure device, the air in the suction cup 4 is discharged to the negative pressure device through the flow channel hole 103, thereby causing the suction cup 4 to adsorb the workpiece 8.

[0039] By providing a flow channel hole 103 at the bottom of the receiving hole 102, it is convenient to install and fix the suction cup 4. On the other hand, it can reduce the use of external pipelines and make the layout of the positioning fixture simpler.

[0040] In addition, the second orifice 1032 of the flow channel hole 103 is arranged on the surface of the material placement component 1 facing the mounting component 2, so that the pipeline between the negative pressure device and the second orifice 1032 can be arranged between the mounting component 2 and the material placement component 1, thereby making full use of the space between the mounting component 2 and the material placement component 1, making the overall layout of the positioning fixture more compact and reducing its space occupation.

[0041] Optionally, the flow channel hole 103 and the receiving hole 102 are coaxially arranged.

[0042] Optionally, the suction cup 4 is threadedly connected to the first orifice 1031. That is, the suction cup 4 has external threads, and the inner wall of the first orifice 1031 has internal threads that mate with the external threads. This arrangement facilitates the disassembly and replacement of the suction cup 4. For example, a suction cup 4 of appropriate size can be replaced according to the area of ​​the adsorption area provided by the workpiece 8, avoiding the problem that the suction cup 4 is too small to provide sufficient adsorption force, or that the suction cup 4 is too large to seal and fit with the workpiece 8.

[0043] Of course, the suction cup 4 can also be connected to the first orifice 1031 by bonding or welding.

[0044] Alternatively, the negative pressure device can be a vacuum pump or a vacuum generator.

[0045] refer to Figure 2 and Figure 3 As shown, in some embodiments provided by this utility model, the positioning element 5 includes a first positioning block 501.

[0046] The first positioning block 501 is used to limit the workpiece 8 in the second direction X. The first positioning block 501 is provided with a first oblong hole 5011 extending in the second direction X. The first oblong hole 5011 passes through the first positioning block 501 in the first direction Z to allow threaded parts to pass through.

[0047] In this embodiment, the workpiece 8 can be positioned in the second direction X by means of the first positioning block 501. By providing a first oblong hole 5011 that runs through the first direction Z on the first positioning block 501, the threaded part can pass through the first oblong hole 5011 and be threadedly connected to the material placement part 1, so as to fix the first positioning block 501 on the material placement part 1 by means of the threaded part.

[0048] In addition, by extending the first waist-shaped hole 5011 along the second direction X, the position of the first positioning block 501 can be adjusted along the second direction X. For example, the first positioning member 5 can be adapted to workpieces 8 of different sizes or shapes, thereby increasing the flexibility and applicability of the positioning fixture.

[0049] refer to Figure 2 and Figure 3 As shown, in some embodiments provided by this utility model, the positioning member 5 includes a second positioning block 502.

[0050] The second positioning block 502 is used to limit the workpiece 8 in the third direction Y. The second positioning block 502 is provided with a second oblong hole 5021 extending in the third direction Y. The second oblong hole 5021 passes through the second positioning block 502 in the first direction Z to allow threaded parts to pass through.

[0051] In this embodiment, the workpiece 8 can be positioned in the third direction Y by the second positioning block 502. By providing a second oblong hole 5021 through the first direction Z on the second positioning block 502, the threaded part can pass through the second oblong hole 5021 and be threadedly connected to the material placement part 1, so as to fix the second positioning block 502 on the material placement part 1 by the threaded part.

[0052] In addition, by extending the second waist-shaped hole 5021 along the third direction Y, the position of the second positioning block 502 can be adjusted along the third direction Y. For example, the first positioning member 5 can be adapted to workpieces 8 of different sizes or shapes, thereby increasing the flexibility and applicability of the positioning fixture.

[0053] In some embodiments provided by this utility model, at least one of the first waist-shaped hole 5011 and the second waist-shaped hole 5021 is configured as a stepped waist-shaped hole. With this configuration, when screwing the threaded part, the head of the threaded part can be positioned inside the stepped waist-shaped hole without protruding from the first positioning block 501 or the second positioning block 502, making the overall structure of the positioning fixture compact and reducing the risk of interference between the head of the threaded part and the cutting tool of the processing equipment.

[0054] In some embodiments provided by this utility model, two sets of positioning members 5 are distributed in the second direction X, and the workpiece 8 is disposed between the two sets of positioning members 5 along the second direction X. For example, two sets of first positioning blocks 501 are distributed in the second direction X, each set of first positioning blocks 501 includes at least one first positioning block 501, and the workpiece 8 is used to be disposed between the two sets of first positioning blocks 501.

[0055] In this embodiment, the two sets of positioning members 5 constrain the workpiece 8 from both sides, which can more accurately control the position of the workpiece 8 in the second direction X and reduce deviation. Dual-sided positioning can also better resist external interference, ensuring that the workpiece 8 remains fixed during processing. The two sets of positioning members 5 can evenly distribute the force, preventing the workpiece 8 from tilting or deforming due to unilateral force, thus improving processing accuracy.

[0056] In some embodiments provided by this utility model, two sets of positioning members 5 are distributed along the third direction Y, and the workpiece 8 is used to be disposed between the two sets of positioning members 5 along the third direction Y. For example, two sets of second positioning blocks 502 are distributed along the third direction Y, each set of second positioning blocks 502 includes at least one second positioning block 502, and the workpiece 8 is used to be disposed between the two sets of second positioning blocks 502.

[0057] In this embodiment, the two sets of positioning elements 5 constrain the workpiece 8 from both sides, which can more accurately control the position of the workpiece 8 in the third direction Y and reduce deviation. Dual-sided positioning can also better resist external interference, ensuring that the workpiece 8 remains fixed during processing. The two sets of positioning elements 5 can evenly distribute the force, preventing the workpiece 8 from tilting or deforming due to unilateral force, thus improving processing accuracy.

[0058] refer to Figure 1 and Figure 2 As shown, in some embodiments provided by this utility model, the workpiece 8 is configured as an annular frame structure, and an inner positioning block 108 is provided on the bearing surface 101. The inner positioning block 108 is used to be located in the annular void portion of the annular frame structure and to abut against the inner side of the workpiece 8.

[0059] In this embodiment, the inner positioning block 108 and the outer positioning element 5 work together to position the workpiece 8, which can evenly distribute the force and prevent the workpiece 8 from tilting or deforming due to force on one side, thereby improving the machining accuracy. In addition, the inner positioning block 108 and the outer positioning element 5 work together to provide multi-point support, which can increase the stability of the workpiece 8 and reduce displacement caused by vibration or external force.

[0060] refer to Figure 1 and Figure 6 As shown, in some embodiments provided by this utility model, the drive assembly 6 includes a fixing part 601 and a drive part 602.

[0061] The fixing part 601 is connected to the surface of the material placement member 1 facing the mounting member 2. Optionally, the fixing part 601 can be connected to the material placement member 1 by a threaded part, for example, the threaded part passes through the fixing part 601 and is threadedly connected to the material placement member 1.

[0062] The drive unit 602 is telescopically disposed at one end of the fixed unit 601 near the material placement member 1 along the first direction Z. The material placement member 1 is provided with a through hole at the position opposite to the drive unit 602. The drive unit 602 passes through the through hole and is connected to the clamping member 7.

[0063] In this embodiment, by placing the fixing part 601 between the material placement part 1 and the mounting part 2, the space between the material placement part 1 and the mounting part 2 can be fully utilized, thereby improving the overall structural compactness of the positioning fixture and reducing the risk of interference between the drive assembly 6 and the processing equipment or other components.

[0064] Optionally, the drive assembly 6 is configured as a cylinder, the cylinder body of which is a fixed part 601 connected to the surface of the material placement member 1 facing the mounting member 2. The piston cylinder of the cylinder is a drive part 602, which is telescopically disposed at the end of the cylinder body near the material placement member 1 along the first direction Z.

[0065] Furthermore, the drive component 6 is configured as a corner cylinder, also known as a rotary pressing cylinder. The corner cylinder can rotate a preset angle during the pressing or opening process. With this configuration, during the process of the corner cylinder driving the clamping member 7 to release the workpiece 8, it can drive the clamping member 7 to rotate a preset angle, so that the clamping member 7 can avoid the workpiece 8, making it easier to pick up and put down the workpiece 8.

[0066] In some embodiments provided by this utility model, the positioning fixture further includes an elastic element 9. The elastic element 9 is disposed on the surface of the clamping member 7 for contacting the workpiece 8, so that the clamping member 7 abuts against the workpiece 8 through the elastic element 9.

[0067] In this embodiment, by providing an elastic element 9 on the clamping element 7, it is possible to prevent the clamping element 7 from damaging the workpiece 8.

[0068] Optionally, the elastic element 9 can be made of urethane, rubber, or silicone.

[0069] Optionally, the clamping member 7 is provided with a groove for mounting the elastic member 9, with one end of the elastic member 9 disposed in the groove and the other end used to abut against the workpiece 8. This arrangement can increase the contact area between the elastic member 9 and the clamping member 7, and increase the connection strength between the elastic member 9 and the clamping member 7.

[0070] Optionally, the elastic element 9 and the clamping element 7 are bonded together.

[0071] refer to Figures 1-2 As shown, in some embodiments provided by this utility model, the mounting part 2 is provided with a relief groove 201 at the position opposite to the fixing part 601, and the fixing part 601 extends into the relief groove 201.

[0072] Because desktop CNC and other machining equipment have a short travel distance, if the height of workpiece 8 is too large, it can easily exceed the travel distance of the machining equipment, making it impossible to process.

[0073] In this embodiment, by providing a clearance groove 201 in the mounting member 2 and extending the fixing part 601 into the clearance groove 201, the distance between the material placement member 1 and the mounting member 2 can be shortened under the premise that the dimension of the fixing part 601 along the first direction Z is constant. This reduces the position height of the workpiece 8 on the processing equipment, so that the processing equipment can process the workpiece 8 and avoid the problem that the position height of the workpiece 8 is too high and exceeds the stroke of the processing equipment.

[0074] In addition, the clearance groove 201 can reduce the weight of the mounting part 2, thereby making the positioning fixture lighter.

[0075] Optionally, the clearance groove 201 penetrates the mounting member 2 along the first direction Z to maximize clearance of the fixing part 601, thereby allowing the material placement member 1 to be as close as possible to the mounting member 2.

[0076] refer to Figures 1-2 As shown, in some embodiments of this utility model, the surface of the material placement member 1 facing the mounting member 2 is provided with a receiving groove 104, and the end of the fixing part 601 facing away from the mounting member 2 is provided in the receiving groove 104. Optionally, the fixing part 601 is connected to the bottom of the receiving groove 104 by a threaded member. For example, the bottom of the receiving groove 104 is provided with a threaded hole, and the threaded member passes through the fixing part 601 and is connected to the threaded hole at the bottom of the receiving groove 104.

[0077] In this embodiment, by providing a receiving groove 104 in the material placement member 1 and extending the fixing part 601 into the receiving groove 104, the distance between the material placement member 1 and the mounting member 2 can be shortened under the premise that the dimension of the fixing part 601 along the first direction Z is constant. This reduces the height of the workpiece 8 on the processing equipment, making it easier for the processing equipment to process the workpiece 8 and avoiding the problem that the position height of the workpiece 8 is too high and exceeds the stroke of the processing equipment.

[0078] In addition, by providing a receiving groove 104 on the material placement part 1, the weight of the material placement part 1 can be reduced, thereby making the positioning fixture lighter.

[0079] refer to Figure 3 and Figure 5 As shown, in some embodiments provided by this utility model, the mounting member 2 is provided with a connecting hole 202 for connecting processing equipment, and the connecting hole 202 penetrates the mounting member 2 along the first direction Z. The material placement member 1 is provided with an operating hole 105 at a position opposite to the connecting hole 202, and the operating hole 105 penetrates the material placement member 1 along the first direction Z.

[0080] In this embodiment, by providing a connecting hole 202 on the mounting member 2, threaded parts and the like can pass through the connecting hole 202, and the mounting member 2 is connected to the fixture mounting plate of the processing equipment, thereby fixing the positioning fixture to the processing equipment.

[0081] In addition, since the space between the material placement component 1 and the mounting component 2 is relatively narrow, it is difficult for the operator to tighten the threaded connection 3 between the material placement component 1 and the mounting component 2 from the side. In this embodiment, by providing an operation hole 105 on the material placement component 1, the operator can directly contact the threaded component through the operation hole 105 and tighten the threaded component, which simplifies the operation process.

[0082] Finally, by providing an operation hole 105 on the material placement part 1, the weight of the material placement part 1 can be reduced, thereby making the positioning fixture lighter.

[0083] refer to Figure 2 As shown, in some embodiments provided by this utility model, the material placement component 1 includes a base plate 106 and a material support plate 107.

[0084] The base plate 106 is connected to the mounting component 2 via the connector 3. The support plate 107 is disposed on the surface of the base plate 106 facing away from the mounting component 2. The area of ​​the support plate 107 is smaller than the area of ​​the base plate 106. The side of the support plate 107 facing away from the base plate 106 has a bearing surface 101. The positioning component 5 is disposed on the base plate 106. Optionally, the support plate 107 and the base plate 106 can be configured as an integrally formed structure, or the two can be connected by welding or fasteners.

[0085] In this embodiment, by providing a support plate 107 on the base plate 106, and since the area of ​​the support plate 107 is smaller than the area of ​​the base plate 106, only the support plate 107 needs to be processed with higher precision. Because the area of ​​the support plate 107 is relatively small, less time is required for high-precision processing, thereby reducing processing costs.

[0086] In addition, the smaller area of ​​the support plate 107 makes it easier to achieve high precision requirements during processing. The smaller area means less error accumulation and higher processing stability, thereby improving the processing accuracy of the material placement part 1.

[0087] This utility model also provides a processing system.

[0088] The machining system includes machining equipment and a positioning fixture as described above, with mounting component 2 connected to the machining equipment. For example, mounting component 2 is connected to the fixture mounting plate of the machining equipment.

[0089] In this embodiment, the machining system includes a positioning fixture, and thus includes all the advantages of the positioning fixture described above.

[0090] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
