Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a clamping device for irregularly shaped parts. Background Technology

[0002] For irregularly shaped parts, machining generally requires auxiliary tooling. Currently, the design and manufacturing scheme is often implemented with one tooling per product, which has obvious advantages, achieving specialization of tooling fixtures. However, for one-off orders, trial orders, and scattered orders, the drawbacks of this dedicated design and manufacturing scheme become apparent, resulting in significant waste of tooling materials and manufacturing costs. To overcome this waste and improve efficiency, it is necessary to provide a new, universal tooling for machining irregularly shaped parts to enable the completion of machining processes for one-off orders, trial orders, and scattered orders in machining centers.

[0003] Existing irregular part clamping devices, such as those described in CN115781338A, include a fixed base plate, a machinable positioning block, a machinable positioning shaft, and a cam lateral clamping block. The fixed base plate has multiple rows of threaded holes arranged in an array at its upper end. Positioning grooves are provided around the upper periphery of each threaded hole. The upper end of the fixed base plate is engraved with coordinate numbers corresponding to the threaded holes in the X and Y directions using a coordinate system. The machinable positioning block includes a first machinable positioning block and a second machinable positioning block. The lower end of each is provided with two positioning bosses that can be inserted into the positioning groove. The upper end of the first and second cuttable positioning blocks is provided with two bolt fixing through holes. A positioning insertion hole is also provided between the two bolt fixing through holes of the second cuttable positioning block. The cuttable positioning shaft includes a first pin at the lower end that can be inserted into the threaded hole or positioning insertion hole and a cuttable frustum at the upper end. The cam side clamping block includes a second pin at the lower end that can be inserted into the threaded hole or positioning insertion hole and a polygonal clamping block at the upper end.

[0004] The aforementioned irregular part clamping device is only suitable for irregular parts with holes, which can be fixed by bolts. It is not suitable for flat platforms with sides.

[0005] Therefore, it is necessary to improve the existing irregular part clamping devices. Utility Model Content

[0011] According to one embodiment of the present invention, the top surface of the mounting base is abutted against the bottom surface of the irregularly shaped part.

[0012] According to one embodiment of the present invention, the positioning block is provided with an inclined surface that abuts against the irregularly shaped part.

[0013] According to one embodiment of the present invention, the limiting component further includes an adsorption unit, which is used to assist in fixing the position of the irregularly shaped part.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] like Figure 1-5 As shown, the irregular part clamping device of this utility model includes a fixedly installed tooling platform 1 and a limiting component that is detachably and fixedly connected to the tooling platform 1. The limiting component includes a positioning unit, and the positioning unit is provided with a positioning block 2 that abuts against the side of the irregular part. The positioning unit is provided with at least three sets.

[0021] This design allows for the adaptation of specific irregularly shaped parts with sides. Clamping is stable and reliable: based on mechanical principles, three or more points can form a stable positioning support. By having at least three sets of positioning units abut against different sides of the irregularly shaped part, displacement of the part can be restricted from multiple directions, ensuring a stable position after clamping and providing a reliable positioning foundation for subsequent processing.

[0022] According to one embodiment of the present invention, the positioning unit further includes a support rod 3 and a base 4 fixedly disposed at the bottom of the support rod 3. The base 4 is provided with a through hole 41, and the tooling platform 1 is provided with a plurality of threaded holes 11. Bolts are inserted into the through hole 41 and threadedly connected to the threaded holes 11.

[0023] With this design, the positioning unit is securely connected and easy to assemble and disassemble: the base and the tooling platform are fixed by bolts passing through the through holes of the base and being threaded into the threaded holes. The threaded engagement of the bolts and the threaded holes provides reliable locking force, ensuring that the positioning unit will not loosen during clamping and processing, thus guaranteeing the positioning stability of irregular parts.

[0024] This bolted connection is a detachable structure. When it is necessary to change the position of the positioning unit or adjust the layout, simply loosen the bolts to move the base. The operation is simple and it is easy to flexibly adjust the position of the limiting components according to the size and shape of different irregular parts, so as to adapt to more diverse clamping needs.

[0025] Highly adaptable and flexible: The tooling platform is equipped with several threaded holes, and the base can be fixed in different positions of the threaded holes, thereby adjusting the distribution position of the positioning unit on the tooling platform; by changing the connection position between the base and different threaded holes, at least three sets of positioning units can accurately match the side contour of the irregular part, further improving the clamping and adaptation capability for various irregular parts.

[0026] According to one embodiment of the present invention, the top of the support rod 3 is provided with a mounting base 5, the mounting base 5 is provided with a sliding groove 51, the positioning block 2 is provided with a sliding rod 21 that is slidably connected to the sliding groove 51, and the sliding rod 21 is damped and slidably connected to the sliding groove 51.

[0027] This design allows for the adaptation of irregularly shaped parts of different sizes, enhancing versatility: the sliding connection between the slide rod and the slide groove allows for direct adjustment of the position of the positioning block relative to the mounting base, enabling adaptation of irregularly shaped parts of different widths and contours without moving the base, making operation convenient and quick.

[0028] To ensure positioning stability and prevent loosening of the clamping mechanism: The damping sliding setting ensures appropriate friction between the slide bar and the slide groove, preventing the positioning block from sliding due to machining vibrations or slight stress on the irregularly shaped part after adjustment. This design retains the flexibility of position adjustment while maintaining the positioning block in contact after clamping, ensuring the stability of the irregularly shaped part during machining.

[0029] According to one embodiment of the present invention, the mounting base 5 and the support rod 3 are configured for damped rotation.

[0030] This design adapts to the irregular sides of irregularly shaped parts, improving positioning flexibility: the damped rotation design allows the mounting base to rotate flexibly relative to the support rod. Because the sides of irregularly shaped parts are irregular, rotating the mounting base adjusts the orientation of the positioning block, making its inclined surface or abutment surface more closely match the side contour of the irregularly shaped part, ensuring a tight fit and solving the problem of fixed angles being unable to adapt to complex sides.

[0031] According to one embodiment of the present invention, the top surface of the mounting base 5 is arranged to abut against the bottom surface of the irregularly shaped part.

[0032] This design provides bottom support and enhances clamping stability: the top surface of the mounting base directly abuts against the bottom surface of the irregular part, providing upward support and counteracting the downward pressure that may be generated during processing.

[0033] Assisted positioning height to adapt to irregular parts of different thicknesses: The support of the top surface of the mounting base can indirectly limit the height position of irregular parts, ensuring that they are in a relatively uniform height plane during processing.

[0034] According to one embodiment of the present invention, the positioning block 2 is provided with an inclined surface 22 that abuts against the irregularly shaped part.

[0035] Improve the fit with irregularly shaped parts and enhance positioning stability: The bevel can better adapt to the tilt, chamfer or irregular contour that may exist on the side of the irregularly shaped parts.

[0036] According to one embodiment of the present invention, the limiting component further includes an adsorption unit, which is used to assist in fixing the position of the irregularly shaped part.

[0037] This design enhances clamping stability and withstands external forces during processing: the adsorption unit applies additional fixing force to the irregularly shaped part through adsorption, forming a double constraint with the side abutment of the positioning unit. During processing, it effectively prevents slight displacement or wobbling of the irregularly shaped part, making it particularly suitable for thin and light irregularly shaped parts, avoiding the loosening that might occur with only side abutment. Furthermore, it can adapt to more types of irregularly shaped parts, improving the device's versatility.

[0038] According to one embodiment of the present invention, the adsorption unit includes a positioning suction cup 6, which is connected to the mounting base 5.

[0039] This design enhances the fixing effect and adapts to various irregularly shaped parts: the positioning suction cup can adhere tightly to the bottom surface of the irregularly shaped part through adsorption force, and works in synergy with the positioning unit through the fixing method of the positioning block abutting the side.

[0040] According to one embodiment of the present invention, the mounting base 5 is provided with a first slot 52, and the support rod 3 is rotatably disposed in the first slot 52.

[0041] This design ensures rotational stability and prevents wobbling: the first slot provides precise limiting space for the rotation of the support rod and the mounting base. When the support rod is embedded in the slot and rotates, there will be no lateral offset or wobbling, ensuring the coaxiality and stability of the mounting base during rotation.

[0042] According to one embodiment of the present invention, the top surface of the positioning suction cup 6 is flush with the top surface of the mounting base 5.

[0043] This design ensures that irregularly shaped parts are placed stably and avoids uneven stress: the top surface of the mounting base itself is used to abut against the bottom surface of the irregularly shaped part, providing support. It also ensures stable adsorption and improves the reliability of the fixation.

[0044] like Figure 6 As shown, in another specific embodiment, the irregularly shaped parts can also be fixed by clamping. The slide rod 21 is located below the positioning block 2. The positioning block 2 is provided with a clamping surface 23 and a supporting surface 24. The orientation of the clamping surface 23 is consistent with the extension direction of the slide rod 21.

[0045] The side of the irregular part is clamped and fixed by the clamping surface 23 of multiple positioning blocks 2, so as to achieve the purpose of fixing the position of the irregular part. After the exposed edge is deburred, the clamping edge can be changed to work on the part that has not been deburred.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
