Description

Technical Field

[0001] This utility model relates to processing machines; in particular, it relates to a detachable clamping device. Background Technology

[0002] As machined parts become increasingly complex, the demands on machining equipment go beyond just machining precision; people are also placing greater emphasis on machining efficiency, product quality, and adaptability to various materials. This trend has led to the development of various machining types, including three-axis, four-axis, and five-axis machining centers.

[0003] Taking a five-axis machining center as an example, in the existing technology, a five-axis machining center must be repositioned when machining workpieces with different structures. The positioning steps include fixture installation, jig installation, alignment and correction, etc., and each step requires precise and accurate operation to ensure the accuracy of workpiece machining.

[0004] However, the repositioning process involves multiple steps, each requiring precise and accurate operation. This results in significant time consumption for each change of machining parts with different structures, increasing overall processing time and reducing production efficiency. Furthermore, inaccurate positioning can also reduce the precision of subsequent machining, thereby affecting the quality of the machined parts. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a detachable clamping device that can increase the efficiency of changing workpieces.

[0006] To achieve the above objectives, this utility model provides a detachable clamping device, disposed on a base of a processing machine. The base includes a turntable and a distributor. The distributor is disposed on the top surface of the turntable and has multiple fluid outlets. The detachable clamping device includes a transfer plate and a clamping base module. The transfer plate has a groove and multiple first flow channels. The groove is located on the bottom surface of the transfer plate and fits onto the distributor. The multiple first flow channels are located inside the transfer plate, and each first flow channel has a first flow channel inlet and a first flow channel outlet. The multiple first flow channel inlets are formed in the groove and correspond to the positions of the multiple fluid outlets, and the multiple first flow channel inlets communicate with the multiple fluid outlets. The multiple first flow channel outlets are formed on the top surface of the transfer plate. The clamping base module includes a chassis and multiple clamps. The chassis is detachably disposed on the turntable. The top surface of the adapter plate has multiple second flow channels formed inside the chassis. Each second flow channel has a second flow channel inlet and a second flow channel outlet. The multiple second flow channel inlets are formed on the bottom surface of the chassis and correspond to the positions of the multiple first flow channel outlets. The multiple second flow channel inlets are connected to the multiple first flow channel outlets. The multiple second flow channel outlets are formed on the top surface of the chassis. Multiple clamps are disposed on the top surface of the chassis. Each clamp has a fluid injection port, and the fluid injection port of each clamp is connected to each of the second flow channel outlets.

[0007] The advantage of this invention is that, through the design that the chassis of the adapter plate and the clamping module can be detached, when it is necessary to replace the clamping module, the clamping module can be quickly detached and replaced with another clamping module and attached to the adapter plate, thereby improving the overall processing efficiency.

In this embodiment, the workpiece clamped by the first clamping base module 20 is a first workpiece W1, and the workpiece clamped by the second clamping base module 60 is a second workpiece W2.

[0074] like Figures 2 to 5As shown, the adapter plate 10 is attached to the base 1. More specifically, the turntable 2 has multiple engagement grooves 2a, each engagement groove 2a having a nut 4, and the nut 4 having a threaded hole 4a. The adapter plate 10 has multiple engagement holes 11 corresponding to the multiple engagement grooves 2a. When the adapter plate 10 is attached to the turntable 2, the adapter plate 10 and the turntable 2 are connected together by multiple connecting members 5 passing through the multiple engagement holes 11 and locking into the multiple threaded holes 4a, and then connecting with the multiple engagement grooves 2a. In this embodiment, each connecting member 5 is a bolt. The bottom surface of the adapter plate 10 is further provided with a pair of alignment members 12, which are positioned corresponding to one of the engagement grooves 2a. When the adapter plate 10 is attached to the turntable 2, the alignment member 12 is first inserted into the corresponding engagement groove 2a and engages with the groove wall of the engagement groove 2a, and then the adapter plate 10 and the turntable 2 are connected by the multiple connecting members 5. Therefore, the misalignment of the adapter plate 10 when assembled to the turntable 2 is avoided, thereby improving the accuracy and stability during processing.

[0075] Please cooperate. Figure 4 , Figures 6 to 7 As shown, the adapter plate 10 has a groove 13 and a plurality of first flow channels 14. The groove 13 is located on the bottom surface of the adapter plate 10 and is fitted with the distributor 3. The plurality of first flow channels 14 are located inside the adapter plate 10. Each first flow channel 14 has a first flow channel inlet 141 and a first flow channel outlet 142. The plurality of first flow channel inlets 141 are formed in the groove 13 and correspond to the positions of the plurality of fluid outlets 3a. The plurality of first flow channel inlets 141 are connected to the plurality of fluid outlets 3a. The plurality of first flow channel outlets 142 are formed on the top surface of the adapter plate 10.

[0076] like Figure 8As shown, the first clamping module 20 includes a first chassis 21, which is detachably disposed on the top surface of the adapter plate 10. More specifically, the top surface of the adapter plate 10 has at least one upper positioning hole, and the first chassis 21 has at least one lower positioning hole corresponding to the position of the at least one upper positioning hole. The adapter plate 10 and the first chassis 21 are connected together by at least one positioning member between the at least one upper positioning hole and the at least one lower positioning hole, thus positioning the relative position of the adapter plate 10 and the first chassis 21.

Through the design of the first positioning element 30 and the second positioning element 40, when the first chassis 21 is assembled onto the adapter plate 10, it can be accurately aligned to prevent the first chassis 21 from rotating or shifting relative to the adapter plate 10, thereby improving the accuracy and stability during processing.

[0078] In this embodiment, the first upper positioning hole 15 and the second upper positioning hole 16 are formed in the following manner. When the adapter plate 10 without the first upper positioning hole 15 and the second upper positioning hole 16 is disposed on the turntable 2, the adapter plate 10 without the first upper positioning hole 15 can first be machined by the cutting tool of the processing machine to form the first upper positioning hole 15. Then, taking the center of the first upper positioning hole 15 as a processing origin, the second upper positioning hole 16 is then machined around the first upper positioning hole 15. Thus, the adapter plate 10 with the first upper positioning hole 15 and the second upper positioning hole 16 is formed.

[0079] like Figure 8 and Figure 9As shown, the top surface of the adapter plate 10 is provided with a plurality of screw holes 17, which are arranged radially outward from the center of the top surface of the adapter plate 10; the first base plate 21 has a plurality of through holes 213, which correspond to a portion of the screw holes 17; the first base plate 21 and the adapter plate 10 are respectively connected by a plurality of couplings 50 passing through the plurality of through holes 213 and locking into the corresponding screw holes 17, wherein each coupling 50 is a bolt, thereby fixing the first base plate 21 to the adapter plate 10. In this embodiment, the first chassis 21 has a plurality of second flow channels 214 formed inside the first chassis 21. Each second flow channel 214 has a second flow channel inlet 214a and a second flow channel outlet 214b.

The plurality of second flow channel outlets 214b are formed on the top surface of the first chassis 21. Unused first flow channel outlets 142 can be blocked by a blocking member B to prevent fluid from flowing out.

Figures 1 to 2 As shown, the first clamping module 20 further includes a plurality of first clamps 22 and a first fixture 23, wherein the plurality of first clamps 22 are disposed on the top surface of the first chassis 21; the first fixture 23 is disposed on the first chassis 21 and located between the plurality of first clamps 22; the first workpiece W1 is clamped on the first fixture 23. In this embodiment, the first clamp 22 clamps and releases the first workpiece W1 by hydraulic pressure; in other embodiments, the first clamp 22 may also clamp and release the first workpiece W1 by pneumatic pressure.

[0081] More specifically, each of the first clamps 22 has a fluid inlet 221, and the fluid inlet 221 of each of the first clamps 22 is connected to the outlet 214b of each of the second flow channels; when hydraulic oil enters each of the second flow channels 214 through each of the first flow channels 14 via a portion of the fluid outlet 3a, and is finally delivered to the first clamp 22 through each of the fluid inlet 221, the first clamp 22 is pressurized and placed in a locked position P1. Figure 1 (Solid line portion) to fix the first workpiece W1; when the first workpiece W1 does not need to be processed, the injection of hydraulic oil into each of the fluid injection ports 221 is stopped, so that a reset element (not shown in the figure) in each of the first clamps 22 pushes the first clamp 22 back to a release position P2. Figure 1 (dashed line portion) to release the first workpiece W1.

[0082] Please refer to Figures 10 to 13 As shown, when the machining machine needs to replace the clamping module, it is only necessary to detach the first clamping module 20 from the adapter plate 10 and then attach the second clamping module 60 to the adapter plate 10 to complete the clamping module replacement operation.

[0085] like Figure 11 and Figure 12 As shown, the top surface of the adapter plate 10 is provided with a plurality of screw holes 17, which are arranged radially outward from the center of the top surface of the adapter plate 10; the second base plate 61 has a plurality of through holes 613, which correspond to a portion of the screw holes 17; the second base plate 61 and the adapter plate 10 are fixed to the adapter plate 10 by a plurality of couplings 50 passing through the plurality of through holes 613 and locking into the corresponding screw holes 17. Figure 13As shown, in this embodiment, the second chassis 61 has a plurality of second flow channels 614, which are formed inside the second chassis 61. Each second flow channel 614 has a second flow channel inlet 614a and a second flow channel outlet 614b. The plurality of second flow channel inlets 614a are formed on the bottom surface of the second chassis 61 and correspond to the positions of the plurality of first flow channel outlets 142, and the plurality of second flow channel inlets 614a and the plurality of first flow channel outlets 142 are in communication. The plurality of second flow channel outlets 614b are formed on the top surface of the second chassis 61. Unused first flow channel outlets 142 can be blocked by a blocking member B to prevent fluid from flowing out.

[0086] Please continue to cooperate. Figure 10 and Figure 11 As shown, the second clamping module 60 further includes a plurality of second clamps 62 and a second fixture 63, wherein the plurality of second clamps 62 are disposed on the top surface of the second chassis 61; the second fixture 63 is disposed on the second chassis 61 and located between the plurality of second clamps 62; the second workpiece W2 is clamped on the second fixture 63. In this embodiment, the second clamp 62 clamps and releases the second workpiece W2 by hydraulic pressure; in other embodiments, the second clamp 62 may also clamp and release the second workpiece W2 by pneumatic pressure.

[0087] More specifically, each of the second clamps 62 has a fluid inlet 621, which is connected to the outlet 614b of each of the second flow channels; when hydraulic oil enters each of the second flow channels 614 through each of the first flow channels 14 via a portion of the fluid outlet 3a, and is finally delivered to the second clamp 62 through each of the fluid inlets 621, the second clamp 62 is pressurized and placed in a locked position P1'.
