Description

Technical Field

[0001] The present application relates to the technical field of clamps, and in particular to a flexible clamp. Background Art

[0002] At present, a special fixture is usually used to clamp and fix the workpiece during the workpiece processing. Since the special fixture has a small application range, when there are many types of workpieces to be processed, it is necessary to design a variety of matching fixtures. In addition, since the fixture will be subjected to a large axial impact force during the processing, the fixture is easily damaged. Therefore, it is urgent to design a fixture that is highly versatile and can withstand a large axial impact force. Utility Model Content

[0003] In view of the above, it is necessary to propose a flexible clamp that is not only highly versatile but also capable of withstanding greater axial impact forces during use.

[0004] The embodiment of the present application provides a flexible clamp, the flexible clamp includes a base, a plurality of spaced accommodating holes are provided on the base, a plurality of spaced through holes are provided on the hole wall of each of the accommodating holes, and two adjacent accommodating holes are connected through one of the through holes; a hydraulic component includes a plurality of annular elastic members and a plurality of hydraulic pipelines, the plurality of annular elastic members correspond to the plurality of accommodating holes one by one and are arranged in the corresponding accommodating holes, the annular elastic member includes an inner ring portion and an outer ring portion, a cavity for accommodating hydraulic fluid is formed between the inner ring portion and the outer ring portion, and the outer ring portion A through hole connecting the cavity and the accommodating hole is opened on it, and a plurality of hydraulic pipelines are arranged at intervals through the side of the base and are respectively connected with the plurality of accommodating holes; a support assembly includes a plurality of support members, and the plurality of support members correspond to the plurality of annular elastic members one by one, and the support members are slidably arranged through the inner ring part of the corresponding annular elastic member and protrude from the base, and the support members are used to support the workpiece, wherein the hydraulic fluid enters the cavity through the hydraulic pipeline, the through hole and the through hole, so that the annular elastic member expands to squeeze and lock the support member.

[0005] In the process of using the above-mentioned flexible clamp, the workpiece is placed on multiple support members.

When the support member needs to be released, it is only necessary to stop pressurizing and pouring hydraulic fluid into the cavity. The locking and unlocking states of the support member are both controlled by hydraulic pressure. Since the hydraulic system can apply a large pressure, the annular elastic member can tightly lock the support member, thereby enabling the support member to withstand a large axial impact force.

[0054] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0055] See also Figure 1 The embodiment of the present application provides a flexible clamp 100. The flexible clamp 100 can perform contour positioning on a workpiece.

[0056] For ease of understanding, Figure 1 A three-dimensional coordinate system is established for auxiliary explanation. The directions of the X-axis, Y-axis and Z-axis are shown in the figure, and the X-axis, Y-axis and Z-axis are perpendicular to each other.

[0057] See also Figures 1 to 3 The flexible clamp 100 includes a base 10, a hydraulic assembly 20 and a support assembly 30. The base 10 is provided with a plurality of spaced accommodation holes 11. In this embodiment, the accommodation holes 11 extend along the Z-axis direction, and the plurality of accommodation holes 11 are arranged in a rectangular array in the X-axis and Y-axis directions. A plurality of spaced through holes 121 are provided on the hole wall of each accommodation hole 11, and two adjacent accommodation holes 11 are connected through a through hole 121.

[0058] See also Figure 2 , Figure 4 and Figure 5 The hydraulic assembly 20 includes a plurality of annular elastic members 21 and a plurality of hydraulic pipelines 22. The plurality of annular elastic members 21 correspond to the plurality of receiving holes 11 one by one, and the plurality of annular elastic members 21 are arranged in the corresponding receiving holes 11. The annular elastic member 21 includes an inner ring portion 211 and an outer ring portion 212, and a cavity 213 for receiving hydraulic fluid is formed between the inner ring portion 211 and the outer ring portion 212. A through hole 214 is provided on the outer ring portion 212, and the cavity 213 is connected to the receiving hole 11 through the through hole 214. In this embodiment, the annular elastic member 21 is made of flexible metal, and when hydraulic fluid is poured into the cavity 213, the annular elastic member 21 will expand. A plurality of hydraulic pipelines 22 are arranged at intervals on the side of the base 10 and are respectively connected to the plurality of receiving holes 11. In the present embodiment, the plurality of hydraulic pipelines 22 are arranged around the circumference of the base 10, and the plurality of hydraulic pipelines 22 correspond one-to-one to the plurality of receiving holes 11 in the outermost layer, and the plurality of hydraulic pipelines 22 are respectively connected to the corresponding receiving holes 11 through the through holes 121.

[0059] The support assembly 30 includes a plurality of support members 31. The plurality of support members 31 correspond to the plurality of annular elastic members 21 one by one, and the plurality of support members 31 are slidably disposed in the inner ring portion 211 of the corresponding annular elastic member 21, and the plurality of support members 31 protrude from the base 10 to support the workpiece.

[0060] When the flexible clamp 100 is used to perform contour positioning on a workpiece, the workpiece is placed on a plurality of support members 31. Since the plurality of support members 31 can slide relative to the annular elastic member 21, the positions of the plurality of support members 31 change according to the surface shape of the workpiece, thereby contour positioning the workpiece. Since the plurality of support members 31 can perform contour positioning on the workpiece, the flexible clamp 100 can position different workpieces, thereby enhancing the versatility of the flexible clamp 100 and making the flexible clamp 100 more widely used. Then, hydraulic fluid is pressurized and poured into the receiving hole 11 through the hydraulic pipeline 22, and the hydraulic fluid flows from the receiving hole 11 into the cavity 213. The annular elastic member 21 expands, and the inner ring portion 211 applies pressure to the peripheral side of the support member 31. When the inner ring portion 211 applies a sufficiently large pressure to the peripheral side of the support member 31, the support member 31 is locked. When the support member 31 needs to be released, it is only necessary to stop pressurizing and pouring hydraulic fluid into the cavity 213. The locking and unlocking states of the support member 31 are both controlled by hydraulic pressure. Since the hydraulic system can apply a relatively large pressure, the annular elastic member 21 can tightly lock the support member 31, thereby enabling the support member 31 to withstand a relatively large axial impact force.

[0061] See also Figures 1 to 3The base 10 includes a first holding block 12 and a second holding block 13. The first holding block 12 and the second holding block 13 abut against each other, and the first holding block 12 is provided with a plurality of first mounting holes 122 arranged at intervals. For example, the first mounting holes 122 are arranged through the first holding block 12 along the Z-axis direction, and the plurality of first mounting holes 122 are arranged in a rectangular array in the X-axis and Y-axis directions. An annular elastic member 21 is arranged in each first mounting hole 122, and the through hole 121 is arranged on the hole wall of the first mounting hole 122, and two adjacent first mounting holes 122 are connected through the through hole 121.

[0062] The second retaining block 13 is provided with a plurality of second mounting holes 131 arranged at intervals, and the plurality of second mounting holes 131 correspond to and are connected with the plurality of first mounting holes 122 one by one, and a receiving hole 11 is formed between the plurality of second mounting holes 131 and the corresponding first mounting holes 122, for example, the second mounting holes 131 are in the form of blind holes. Thus, by setting the base 10 as a split structure, it is convenient for operators to assemble the annular elastic member 21 on the base 10.

[0063] See also Figure 1 The side of the base 10 is provided with a plurality of spaced accommodating grooves 14. In this embodiment, the plurality of accommodating grooves 14 are arranged around the circumference of the base 10. The accommodating grooves 14 penetrate the first holding block 12 and the second holding block 13 along the Z-axis direction. Each accommodating groove 14 accommodates a hydraulic pipeline 22. In this way, since the hydraulic pipeline 22 is accommodated in the accommodating groove 14, the accommodating groove 14 protects the hydraulic pipeline 22.

[0064] See also Figure 1 , Figure 2 and Figure 4 The hydraulic assembly 20 further includes a plurality of annular blocks 23, a plurality of sealing members 24 and a pressure detection member 25. An annular block 23 is respectively disposed at both ends of each receiving hole 11 and the two annular blocks 23 are sleeved on the support member 31 in the corresponding receiving hole 11. The two annular blocks 23 in each receiving hole 11 are respectively located at both ends of the corresponding annular elastic member 21 in the receiving hole 11. In this way, since the annular block 23 is sleeved on the support member 31, the annular block 23 constrains the circumferential movement of the support member 31, so that the support member 31 moves along the Z axis.

[0065] The seal 24 is annular and made of rubber. A seal 24 is sleeved on both ends of each annular elastic member 21. The seal 24 on each annular elastic member 21 is located in the corresponding receiving hole 11, and the two seals 24 on each annular elastic member 21 are located between the two annular blocks 23 in the corresponding receiving hole 11. The seal 24 abuts against the hole wall of the receiving hole 11 to seal the gap between the annular elastic member 21 and the hole wall of the receiving hole 11. In this way, when the hydraulic fluid flows from the hydraulic pipeline 22 into the receiving hole 11, the seal 24 can prevent the hydraulic fluid from leaking out of the receiving hole 11.

[0066] The pressure detecting component 25 can be a pressure gauge. The pressure detecting component 25 is inserted into the first retaining block 12 of the base 10. The detecting end of the pressure detecting component 25 is located in the accommodating hole 11. The pressure detecting component 25 is used to detect the pressure of the hydraulic fluid in the accommodating hole 11. When the pressure detected by the pressure detecting component 25 reaches a predetermined value, the pressure-injecting hydraulic fluid into the annular elastic component 21 is stopped.

[0067] See also Figure 2 and Figure 6 The support member 31 includes a pin 311 and a flexible contact head 312. The pin 311 is slidably disposed in the corresponding annular elastic member 21 and protrudes from the base 10. Specifically, the pin 311 is in the shape of a stepped shaft. The end of the pin 311 with a smaller diameter is slidably disposed in the two annular blocks 23 and the annular elastic member 21, and the pin 311 protrudes from the first retaining block 12 to support the workpiece. The end of the pin 311 with a larger diameter is located in the second mounting hole 131 of the second retaining block 13. When the pin 311 slides, the end of the pin 311 with a larger diameter can abut against the first retaining block 12 to limit the pin 311 and prevent the pin 311 from detaching from the first retaining block 12.

[0068] The flexible contact head 312 can be made of materials such as rubber, plastic steel or silicone. The flexible contact head 312 is connected to the end of the pin 311 away from the base 10. Since the flexible contact head 312 is made of a soft material, it can avoid scratching the workpiece when the flexible contact head 312 contacts the workpiece, so as to protect the workpiece. The surface of the flexible contact head 312 is an arc surface. When the flexible contact head 312 abuts against the workpiece, the flexible contact head 312 is in point contact with the workpiece. In this way, when the workpiece is placed on multiple support members 31, since the multiple support members 31 are in point contact with the workpiece, the multiple support members 31 can position the workpiece more accurately.

[0069] In this embodiment, the flexible contact head 312 and the pin shaft 311 are plug-in connected. The flexible contact head 312 is provided with a plug-in portion 313, and the pin shaft 311 is provided with a plug hole 314 at one end away from the base 10. The plug-in portion 313 is plugged into the plug hole 314. It can be understood that the plug-in portion 313 and the plug hole 314 are interference fit. When the flexible contact head 312 is worn or damaged during use, it is only necessary to pull out the old flexible contact head 312 from the pin shaft 311 and plug in a new flexible contact head 312.

[0070] See also Figure 2 The support assembly 30 further includes a plurality of reset members 32, which may be springs. The plurality of reset members 32 correspond to the plurality of receiving holes 11 one by one, and are disposed in the corresponding receiving holes 11, that is, the plurality of reset members 32 are disposed in the corresponding second mounting holes 131, and the two ends of the reset members 32 abut against the larger diameter end of the support member 31 and the second retaining block 13 of the base 10, respectively. The support member 31 elastically abuts against the workpiece under the elastic action of the reset member 32, thereby preventing the support member 31 from hard contact with the workpiece, and further preventing the support member 31 from causing damage to the workpiece; in addition, when the locking state of the support member 31 is released, the support member 31 is reset under the elastic action of the corresponding reset member 32.

[0071] See also Figure 7 The flexible clamp 100 further includes a connector 40 and a fixing member 50. The connector 40 is a plate-like structure, and the two ends of the connector 40 are used to respectively abut against the bases 10 of two adjacent flexible clamps 100. The fixing member 50 can be a bolt, and a plurality of fixing members 50 are respectively penetrated at each end of the connector 40, and the connector 40 is connected to the base 10 through the plurality of fixing members 50. By connecting the connector 40 and the fixing member 50, a plurality of flexible clamps 100 can be spliced ​​together, thereby forming a larger flexible clamp 100, so as to position a larger workpiece.

[0072] The working process of the flexible clamp 100 provided in the embodiment of the present application is roughly as follows:

[0073] The workpiece is placed on a plurality of support members 31, and the flexible contact heads 312 on the plurality of support members 31 abut against the workpiece to position the workpiece. Since the support members 31 can slide relative to the base 10, the positions of the plurality of support members 31 will change according to the surface shape of the workpiece, so as to better fit the surface of the workpiece. Then, hydraulic fluid is pressurized and poured into the cavity 213 of the annular elastic member 21. When the cavity 213 is filled with hydraulic fluid, the annular elastic member 21 will expand, and the inner ring portion 211 will apply pressure to the support member 31. When the inner ring portion 211 applies a sufficiently large pressure to the support member 31, the inner ring portion 211 locks the support member 31, and the support member 31 maintains the current state. When the hydraulic fluid is stopped being pressurized and poured into the cavity 213 of the annular elastic member 21, the support member 31 is reset under the elastic action of the corresponding reset member 32.

[0074] Since the flexible device 100 uses a plurality of floating support members 31 to support the workpiece, when the workpiece abuts against the plurality of support members 31, the plurality of support members 31 can move according to the shape of the workpiece to perform contour positioning on the workpiece. Since the flexible device 100 can perform contour positioning on the workpiece, the flexible device 100 can position different workpieces, and the plurality of floating support members 31 enhances the versatility of the flexible device 100. In addition, the present embodiment uses hydraulic control to lock and unlock the support member 31. Since the hydraulic system can apply a large pressure, the annular elastic member 21 can tightly lock the support member 31, thereby enabling the support member 31 to withstand a large axial impact force.

[0075] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
