Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile accessory processing, in particular to a clamp and clamping method. BACKGROUND

[0002] In the automobile manufacturing industry, especially in the field of new energy vehicles, aluminum profiles have become the preferred material for manufacturing key components such as crash beams due to their lightweight and high-strength characteristics. In traditional mechanical processing, clamps are one of the important tools to ensure processing accuracy and efficiency. However, existing clamp technology relies heavily on manual or semi-automatic adjustment, which not only complicates the operation, but also requires multiple changes and repositioning of the clamp when facing complex-shaped parts that need multi-surface processing. For example, for the processing of curved crash beams of automobiles, the traditional clamp solution requires manual disassembly and re-clamping of the workpiece after completing the processing of one side in order to process the other side. This process not only consumes time, but also easily introduces cumulative errors, affecting the quality and performance of the final product.

[0003] In the current field of mechanical processing, especially for automobile parts that require multi-surface processing, such as new energy vehicle crash beams, existing clamp technology has significant limitations in terms of efficiency and accuracy. The main problems are: first, the extension of processing time, as traditional clamps require manual repositioning and clamping of the workpiece after completing the processing of one side to process the other side, which not only consumes a lot of time, but also significantly reduces the overall efficiency of the production line. Second, cumulative errors affect the final processing quality, and repeated manual clamping cannot guarantee the accurate consistency of each positioning, especially for complex-shaped parts, which can easily lead to slight positional deviations, affecting the dimensional accuracy and geometric tolerance of the parts. Third, frequent manual operations increase labor intensity and pose a high safety risk when quickly changing clamps, such as collisions and pinches. Finally, the customized design of traditional clamps makes them less adaptable and flexible, and when faced with product updates or changes in processing tasks, they often need to be redesigned and manufactured, increasing additional costs and cycle time.

DETAILED DESCRIPTION

[0026] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0027] ​In the automobile manufacturing industry, especially in the field of new energy vehicles, aluminum profiles have become the preferred material for manufacturing key components such as crash beams due to their lightweight and high-strength characteristics. In traditional mechanical processing, fixtures are one of the important tools to ensure processing accuracy and efficiency. However, existing fixture technology relies heavily on manual or semi-automatic adjustment, which is not only complex to operate, but also requires multiple changes and repositioning of the fixture when facing complex-shaped parts that need multi-surface processing. For example, in the processing of curved crash beams for automobiles, the traditional fixture solution requires manual disassembly and re-clamping of the workpiece after completing the processing of one side in order to process the other side. This process not only consumes time, but also introduces cumulative errors, affecting the quality and performance of the final product.

[0028] In the current field of mechanical processing, especially for automobile parts that require multi-surface processing, such as the crash beams of new energy vehicles, existing fixture technology has significant limitations in terms of efficiency and accuracy. The main problems are: first, the extension of processing time, as traditional fixtures require manual repositioning and clamping of the workpiece after completing the processing of one side in order to process the other side. This process not only consumes a lot of time, but also significantly reduces the overall efficiency of the production line. Second, cumulative errors affect the final processing quality, and repeated manual clamping cannot guarantee the accurate consistency of each positioning, especially for complex-shaped parts, which can easily lead to slight positional deviations, affecting the dimensional accuracy and geometric tolerance of the parts. Third, frequent manual operations increase labor intensity and pose a high safety risk when quickly changing fixtures, such as collisions and pinching injuries. Finally, the customized design of traditional fixtures makes them less adaptable and flexible, and when faced with product updates or changes in processing tasks, they often need to be redesigned and manufactured, increasing additional costs and cycle time.

[0029] The main purpose of the present application is to provide a fixture and clamping method to solve the problem of low processing efficiency and accuracy loss caused by multiple clamping of multi-surface processed parts in traditional fixtures.

[0030] Embodiment 1

[0031] As shown in Figures 1 to 3 The present application provides a fixture, which includes a fixture plate body 10, a guide structure 20 arranged on the fixture plate body 10, the guide structure 20 including a plurality of guide components 201 arranged in a predetermined direction, each guide component 201 being rotatably arranged relative to the fixture plate body 10, and each guide component 201 forming a guide track for accommodating a target workpiece 30, and a pushing structure arranged on the fixture plate body 10, the pushing structure being movably arranged in multiple directions to push the target workpiece 30 on the fixture plate body 10 from a current position to a target position to complete positioning of the fixture plate body 10.

[0032] The jig provided by the embodiment of the present application can automatically adjust to adapt to target workpieces 30 of different sizes and shapes by setting a rotatable guide structure 20 and a pushing structure movable in multiple directions on the jig plate body 10, and can realize rapid and accurate workpiece positioning and multi-surface machining. Compared with the prior art, the jig significantly improves the machining efficiency, reduces human errors caused by multiple clamping, enhances the machining precision, and reduces the labor intensity and safety risk of the operator through automatic operation, and improves the flexibility and adaptability of the production line. The technical scheme is suitable for machining of complex parts such as the bumper beam of a new energy vehicle, and can meet the modern manufacturing requirements of high precision and high efficiency.

[0033] In the embodiment, the connecting line of the center lines of the guide components 201 is arc-shaped.

[0034] By designing the connecting line of the center lines of the guide components 201 as arc-shaped, the geometry of the target workpiece 30 can be better adapted, especially in the case of a target workpiece 30 having a curved surface or a complex contour, to provide more accurate and stable guidance. This design not only significantly improves the efficiency and precision of the positioning of the target workpiece 30, reduces the preparation time before machining, but also reduces the machining errors caused by inaccurate positioning, and improves the machining quality and product consistency. At the same time, the multi-directional movement capability of the pushing structure ensures that the target workpiece 30 can complete multi-surface machining in a single clamping, avoiding the cumulative errors and additional time loss that may be caused by multiple clamping, greatly improving the machining efficiency and reducing the production cost. In addition, automatic operation also reduces manual intervention, reduces labor intensity, and improves work safety, providing strong technical support for high-precision and high-efficiency machining of complex parts such as the bumper beam of a new energy vehicle in modern automobile manufacturing.

[0035] In the embodiment, each guide component 201 comprises: a support component arranged on the jig plate body 10, the extension direction of the support component being perpendicular to the upper surface of the jig plate body 10; and a rotating component rotatably arranged on the support component along a first axis, so that when the pushing structure pushes the target workpiece 30, the rotating component rotates relative to the support component about the first axis; wherein the extension direction of the first axis is parallel to the extension direction of the support component.

[0036] The embodiment of the present application introduces the combination of the support component and the rotating component in the design of the guide component 201. The support component extends perpendicular to the upper surface of the jig plate body 10, not only providing stable basic support, but also serving as the rotation axis of the rotating component, so that the rotating component can flexibly rotate about the first axis under the action of the pushing structure. This design allows the guide component 201 to adapt to different shapes and sizes of the target workpiece 30, thereby forming an arc-shaped guide track that better fits the contour of the workpiece, reduces friction and damage during positioning, and improves the stability and precision of positioning.

[0037] In addition, the movable characteristics of the pushing structure in multiple directions enable it to independently or cooperatively push the target workpiece 30 in the X, Y, Z three coordinate axes directions until it is accurately moved to the required target position. Such multi-directional pushing capability not only reduces the time required for positioning the target workpiece 30, but also avoids the necessity of multiple clamping of the target workpiece 30, greatly reduces the error of human operation, and improves the automation level and production efficiency of the entire machining process.

[0038] In the embodiment, the pushing structure comprises: a first pushing component 40, at least a part of the first pushing component 40 is arranged on the clamp plate body 10, and the first pushing component 40 is located on one side of the guide structure 20; and a first positioning component 50 arranged on the side of the clamp plate body 10 away from the first pushing component 40, so as to push the target workpiece 30 in the first direction by the first pushing component 40, and make the end of the target workpiece 30 away from the first pushing component 40 abut against the first positioning component 50, so as to position the target workpiece 30 in the first direction.

[0039] The multi-directional movement capability of the pushing structure, especially the positioning system composed of the first pushing component 40 and the first positioning component 50, can effectively accurately push the target workpiece 30 from the current position to the target position, and complete the positioning of the target workpiece 30 in the first direction. The mutual cooperation between the first pushing component 40 and the first positioning component 50 ensures that the target workpiece 30 will not be offset or deformed during being pushed to the positioning position, and improves the reliability of positioning, wherein the first pushing component 40 is a pushing cylinder.

[0040] By using the clamp, not only the clamping frequency of the target workpiece 30 can be reduced, and the cumulative error caused by multiple clamping can be avoided, but also the machining precision can be greatly improved, the feeding and discharging time can be significantly shortened, the machining efficiency can be improved, and the production cost can be reduced. In addition, due to the improvement of automation degree, the labor intensity of the operator is reduced, and the work safety is enhanced.

[0041] In the embodiment, the first positioning component 50 comprises: a first positioning part 501 detachably arranged on the clamp plate body 10, the first positioning part 501 having a first positioning edge; and a second positioning part 502 detachably arranged on the first positioning part 501, the second positioning part 502 having a second positioning edge.

[0042] The first positioning edge and the second positioning edge jointly form a first positioning surface, the first positioning surface is arranged obliquely relative to the clamp plate body 10, the included angle between the first positioning surface and the clamp plate body 10 is a first acute angle, and the first acute angle is arranged towards the target workpiece 30, so as to position the target workpiece 30 by the first positioning surface when the target workpiece 30 contacts the first positioning surface.

[0043] The detachable design of the first positioning part 501 and the second positioning part 502 enables the operator to quickly replace or adjust the positioning parts according to the size and shape requirements of the target workpiece 30, realizes efficient positioning of different workpieces, and improves the versatility of the clamp and the flexibility of the production line. The inclination of the first positioning surface and the design of the first acute angle enable the target workpiece 30 to be more stably fitted on the positioning surface when in contact with the first positioning surface, using its own gravity and contact friction, reducing the shaking and displacement of the target workpiece 30 during positioning, and ensuring the stability of positioning and the precision of processing.

[0044] The first positioning surface formed by the first positioning edge and the second positioning edge has a more accurate contact area and contact point with the target workpiece 30, can exert a more uniform positioning force on the target workpiece 30, and avoids the deformation of the workpiece caused by excessive local pressure in traditional positioning methods, thereby improving the processing precision and product quality.

[0045] In this embodiment, the pushing structure further includes: a second pushing part 60 arranged on the clamp plate body 10, the second pushing part 60 being a plurality of; a second positioning part 70 arranged on one side of the guide structure 20 of the clamp plate body 10, the second positioning part 70 being a plurality of, each second positioning part 70 being arranged in one-to-one correspondence with each second pushing part 60, so as to push the target workpiece 30 in the second direction by the second pushing part 60, so that at least part of the side of the target workpiece 30 abuts against the second positioning part 70, so as to position the target workpiece 30 in the second direction.

[0046] Optionally, the second pushing part 60 is a pushing air cylinder.

[0047] The arrangement of the second pushing part 60 and the second positioning part 70 cooperates with the first pushing part 40 and the first positioning part 50 to realize all-around positioning of the target workpiece in X, Y and Z directions, ensure the stability of the target workpiece 30 in multi-surface machining, and avoid machining errors caused by unstable clamping.

[0048] The corresponding arrangement of the second pushing part 60 and the second positioning part 70 makes the positioning of the target workpiece 30 in the second direction more accurate. Each second pushing part 60 is specially used to push the target workpiece 30 to contact the corresponding second positioning part 70. This precise point-to-point positioning reduces the shaking of the workpiece during positioning and improves the positioning accuracy.

[0049] The cooperation of the guide structure 20 and the pushing structure enables the target workpiece 30 to move smoothly along the arc-shaped guide track when being pushed to the positioning position, reduces the friction and impact of the target workpiece 30 during positioning, and reduces the risk of workpiece damage.

[0050] In the embodiment, the pushing structure further comprises: a third pushing component 80 arranged on the clamp plate body 10, the third pushing component 80 being a plurality of; a third positioning component 90 arranged on the third pushing component 80, so that when the target workpiece 30 is in the target position, the third positioning component 90 is driven by the third pushing component 80 to move along the third direction, so that the third positioning component 90 is in contact with at least part of the target workpiece 30, and the pressing force is applied to the target workpiece 30.

[0051] The addition of the third pushing component 80 and the third positioning component 90 enables the clamp to simultaneously position and clamp the target workpiece 30 in three dimensions X, Y and Z, realizes three-dimensional positioning and clamping, and greatly improves the positioning accuracy and the stability of the target workpiece 30 during processing.

[0052] After the third positioning component 90 contacts the target workpiece 30, the pressing force can be directly applied to the target workpiece 30. Compared with the traditional single-direction pressing, the multi-directional pressing force is more uniform, which reduces the workpiece deformation caused by uneven pressing force distribution during processing, and improves the processing precision and product quality.

[0053] Through the cooperative work of the third pushing component 80 and the guide structure 20, the target workpiece 30 can be fine-tuned and finally positioned from multiple angles after entering the positioning area. This multi-angle adjustment capability enables the clamp to better adapt to various special-shaped workpieces, improving the versatility of the clamp and the adaptability of the production line.

[0054] Through the cooperative action of the first pushing component 40, the second pushing component 60 and the third pushing component 80, the target workpiece 30 can complete multi-surface positioning in a single clamping, without repeated clamping, greatly reducing the time and potential cumulative error of repeated positioning of the workpiece, and significantly improving the processing efficiency and precision.

[0055] In the embodiment, the pushing structure further comprises: an auxiliary pressing member 100 movably arranged on the clamp plate body 10 along the third direction, so that when the third pushing component 80 contacts the target workpiece 30, an auxiliary pressing force is applied to the target workpiece 30.

[0056] Embodiment 2

[0057] The application also provides a clamping method for clamping the target workpiece 30, which is suitable for the clamp described above, and the clamping method comprises: when the target workpiece 30 is on the clamp plate body 10 of the clamp, controlling the first pushing component 40 to push the target workpiece 30 along the first direction, so that the end of the target workpiece 30 abuts against the first positioning component 50;

[0058] When the end of the target workpiece 30 abuts against the first positioning component 50, the second pushing component 60 is controlled to push the target workpiece 30 in the second direction, so that at least part of the side wall surface of the target workpiece 30 abuts against the second positioning component 70, to position the target workpiece 30 in the second direction;

[0059] When at least part of the side of the target workpiece 30 abuts against the second positioning component 70, the third pushing component 80 is controlled to move in the third direction, so that the third positioning component 90 abuts against the target workpiece 30, to position the target workpiece 30 in the third direction; wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0060] In the embodiment, when the third positioning component 90 abuts against the target workpiece 30, the auxiliary pressing member 100 is controlled to move in the third direction, so that the auxiliary pressing member 100 abuts against the target workpiece 30, to apply an auxiliary pressing force to the target workpiece 30.

[0061] In the embodiment, the step of controlling the first pushing component 40 to push the target workpiece 30 in the first direction, so that the end of the target workpiece 30 abuts against the first positioning component 50, is repeatedly performed, to complete the positioning of the target workpiece 30.

[0062] The clamping method fully utilizes the positioning and clamping functions in the first, second and third directions, realizes accurate positioning and stable clamping of the target workpiece 30 in the three-dimensional space, and effectively avoids workpiece deformation or positioning error caused by single surface positioning. By accurately controlling the action sequence of each pushing component, the target workpiece 30 can be positioned in multiple directions in a single clamping, without the need for secondary or multiple clamping, greatly reducing the target workpiece 30 loading and unloading time, and improving the processing efficiency.

[0063] The multi-directional positioning and clamping ensure that the position of the target workpiece 30 does not change during the entire machining process, thereby significantly improving the machining precision and avoiding quality problems caused by the position change of the target workpiece 30, such as tool vibration and uneven machining edges.

[0064] The automatic control of the pushing components and the operation of the auxiliary pressing member 100 reduces the need for manual intervention, reduces the operation risk, and improves the safety during the machining process.

[0065] The arc-shaped design and smooth guidance of the guide component 201, and the soft pushing force of the pushing component, reduce the friction and collision of the target workpiece 30 during positioning and clamping, effectively prevent the damage of the workpiece surface, and ensure the appearance quality of the finished product.

[0066] When the target workpiece 30 is placed on the fixture plate body 10, the control system activates the first pushing component 40 to push the target workpiece 30 in the first direction until the end of the target workpiece 30 is in full abutment with the first positioning component 50, completing the preliminary positioning of the target workpiece 30 in the first direction.

[0067] Subsequently, the second pushing component 60 is activated to push the target workpiece 30 in the second direction until the side wall of the target workpiece 30 is in abutment with the second positioning component 70, completing the positioning of the target workpiece 30 in the second direction.

[0068] The third pushing component 80 is then activated to move the third positioning component 90 in the third direction to contact the target workpiece 30 and apply a positioning force, completing the positioning of the target workpiece 30 in the third direction.

[0069] After the positioning in the third direction, the auxiliary pressing component 100 is controlled to move in the third direction to contact the target workpiece 30 and apply an additional pressing force, ensuring the stability of the target workpiece 30 during the machining process, especially for the overhanging or weak parts of the target workpiece 30, further enhancing the positioning stability.

[0070] To ensure the positioning accuracy, the system repeatedly performs the positioning step in the first direction, i.e., the first pushing component 40 is controlled to push the target workpiece 30 again to check whether the initial positioning is accurate, and if necessary, fine-tune the positioning to ensure the accuracy of the positioning of the target workpiece 30.
