[0037] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0038] The ABS valve block five-axis machining fixture of the utility model is a fixture suitable for the ABS valve block. When clamping the ABS valve block, the machine tool can perform five-axis machining on the ABS valve block. Of course, the utility model is not limited to clamping the ABS valve block, and can also be used to clamp other workpieces.

[0039] like Figures 1 to 3As shown, in this example, the five-axis machining fixture of the ABS valve block of the utility model includes a chassis 10, a dividing plate 20, a clamping member 30, a positioning plate 40 and a positioning assembly 50. Among them, the chassis 10 is fixed on the workbench of the machine tool and can rotate with the workbench to facilitate the machining of the ABS valve block. The dividing plate 20 is detachably mounted on the chassis 10, and different dividing plates 20 can be disassembled and replaced for different ABS valve blocks. The upper part of the dividing plate 20 has at least two mounting surfaces 221 with a certain angle, and the mounting surfaces 221 are used to mount the ABS valve block to be processed. Specifically, a clamping member 30 that can clamp the ABS valve block is embedded in the groove of each mounting surface 221. Of course, the mounting surfaces 221 can also be three or more, but too many mounting surfaces will affect the five-axis machining process space of the ABS valve block, which is inconvenient for machining. Therefore, the more appropriate number of mounting surfaces is 2. The subsequent examples are explained by taking two ABS valve blocks, that is, two mounting surfaces 221 as examples. A clamping member 30 is installed on each of the two mounting surfaces 221, so as to clamp two ABS valve blocks to be processed at the same time, and then carry out the subsequent processing process. In a further example, the angle between the two mounting surfaces 221 is 100° to 140°; in another preferred example, the angle between the two mounting surfaces 221 is 110° to 130°; in a more preferred example, the angle between the two mounting surfaces 221 is 120°. In this way, the best processing space is reserved for subsequent ABS five-axis processing. The positioning plate 40 is detachably arranged on the side of the clamping member 30 to locate the position of the ABS valve block, thereby ensuring the accuracy of the processing, and different positioning plates 40 can be disassembled and replaced for different ABS valve blocks. The positioning assembly 50 is fixed on the chassis 10, and the positioning assembly 50 forms a positioning cavity 53 that matches the outer shape of the dividing plate 20. The dividing plate 20 is embedded in the positioning cavity 53 of the positioning assembly 50. The dividing plate 20 can be replaced for different valve block processing requirements. By providing the positioning assembly 50 , the replaced indexing plate 20 only needs to be directly inserted into the positioning cavity 53 and then fixed to be positioned, thereby saving time when installing the indexing plate 20 and achieving rapid positioning of the indexing plate 20 .

[0040] like Figure 1 and Figure 3 As shown, in this example, the indexing plate 20 has an indexing bottom plate 21 and an indexing top plate 22. The indexing bottom plate 21 is detachably mounted on the bottom plate 10, and can be disassembled and replaced for different ABS valve blocks. The indexing top plate 22 is integrally formed with the indexing bottom plate 21, and two mounting surfaces 221 with a certain angle are formed on the upper part of the indexing top plate 22. As mentioned above, a clamping member 30 is embedded on the mounting surface 221, and a positioning plate 40 is provided on the side of the clamping member 30.

[0041] like Figure 2As shown, in this example, the clamping member 30 has a clamping cylinder 31, a clamping sleeve 32 and a clamping nut 33. The clamping cylinder 31 is fixed on the top of the indexing plate 20, specifically, for example, fixed on the mounting surface 221 of the indexing top plate 22 of the indexing plate 20 by bolts, and the positioning plate 40 passes through the piston rod of the clamping cylinder 31 and is connected to the cylinder barrel of the clamping cylinder 31. The clamping sleeve 32 is sleeved outside the piston rod of the clamping cylinder 31. The clamping nut 33 is fixedly connected to the piston rod of the clamping cylinder 31 and is pressed on the upper end of the clamping sleeve 32. When the piston rod of the clamping cylinder 31 moves toward the direction of the clamping cylinder 31, the clamping nut 33 squeezes the clamping sleeve 32 and applies axial force to the clamping sleeve 32, so that the clamping sleeve 32 expands, that is, the diameter of the clamping sleeve 32 becomes larger, thereby firmly fixing the ABS valve block sleeved on the clamping sleeve 32.

[0042] Continue as Figure 2 As shown, in a further example, the five-axis machining fixture of the ABS valve block of the utility model further includes an oil circuit 60 (controlling release (piston rod retraction)) or an oil circuit 70 (controlling clamping (piston rod extension)). The oil circuit 60 is connected to the oil supply port of the workbench, and then passes through the chassis 10 and the dividing plate 20 in sequence and communicates with the clamping cylinder 31 to supply oil to the clamping cylinder 31.

[0043] like Figure 1 and Figure 3As shown, in this example, the positioning plate 40 has a positioning chassis 41 and a positioning pin 42. The positioning chassis 41 is detachably mounted on the top of the clamping member 30, specifically, the positioning chassis 41 passes through the piston rod of the clamping cylinder 31 and is arranged on the side of the clamping cylinder 31. There are several positioning pins 42 and they can have various shapes, such as diamond positioning pins, cylindrical positioning pins, etc. Several positioning pins 42 are fixed on the positioning chassis 41 at intervals. When the ABS valve block is sleeved on the clamping expansion sleeve 32, different positioning pins 42 are used to correspond to different holes on the ABS valve block for positioning, thereby ensuring the processing accuracy. In another example, the positioning chassis 41 also has an airtight hole 411, an air duct (not shown) and an adapter groove 413. There are several airtight holes 411 for airtight detection. Several airtight holes 411 are located inside the positioning chassis 41 to detect whether each position of the ABS valve block is tightly attached to the positioning chassis 41. The airtight holes 411 are not connected to each other, so as to identify which position on the ABS valve block is not tightly attached. There are also several air passages, each of which corresponds to an airtight hole 411. One end of the air passage passes through the chassis 10 and the dividing plate 20 in sequence and is connected to the corresponding airtight hole 411 on the positioning chassis 41, and the other end of the air passage is connected to the airtight detection device of the workbench. When the ABS valve block is clamped on the clamping member 30, the air ejected from each airtight hole 411 enters the airtight detection device through the air passage 412. Since the airtight holes 411 are not connected to each other, the amount of air ejected from the airtight holes 411 at the clamped position or the air flow rate is different from that at the unclamped position, so it is possible to detect whether the ABS valve block is clamped and the position of the unclamped position. The adapting groove 413 is located on the top surface of the positioning chassis 41 so as to reserve space for components on the ABS valve block.

[0044] like Figure 1As shown, in this example, the positioning assembly 50 has a first positioning block 51, a second positioning block 52 and a positioning cavity. The first positioning block 51 and the second positioning block 52 can be multiple. Taking two first positioning blocks 51 and two second positioning blocks 52 as an example, the two first positioning blocks 51 are detachably mounted on the chassis 10 close to the two opposite first sides of the dividing plate 20, and are used to position the dividing plate 20 in a first direction, and the first direction is also the axial direction of the first positioning block 51; the two second positioning blocks 52 are also detachably mounted on the chassis 10 close to the two opposite second sides of the dividing plate 20, and are used to position the dividing plate 20 in a second direction, and the second direction is also the axial direction of the second positioning block 52. In a preferred example, the first positioning block 51 and the second positioning block 52 cooperate with each other to form a positioning cavity, and the positioning cavity is consistent with the outer shape of the dividing plate 20. When replacing the dividing plate 20, the dividing plate 20 can be directly embedded in the positioning cavity to quickly achieve positioning. The angle between the first direction and the second direction is greater than 0° and less than 180°, that is, the first direction and the second direction are not parallel, thereby ensuring that the positioning cavity can accurately realize the positioning function of the dividing plate 20. In a preferred example, the angle between the first direction and the second direction is 30°~150°, and in a more preferred example, the angle between the first direction and the second direction is 90°.

[0045] In summary, the utility model provides a dividing plate 20 and a clamping member 30, and has at least two mounting surfaces 221 with a certain angle on the upper part of the dividing plate 20, and at least two clamping members 30 are provided on the corresponding mounting surfaces 221 of the dividing plate 20, so that at least two ABS valve blocks can be installed on the fixture at the same time, and any ABS valve block can be processed by five axes. When one ABS valve block is processed, the machine tool can directly process the next ABS valve block without waiting for the replacement of the ABS valve block, thereby improving production efficiency and speeding up production.
