[0021] like Figure 1-Figure 3 As shown, the utility model provides a multi-station fixture for valve processing.

[0022] In an exemplary embodiment, a multi-station fixture for valve processing includes a fixed seat, which is provided with multiple positioning surfaces 3, each of which is provided with a locking member 4 for fixing the valve 14, a positioning mechanism is provided on the fixed seat, and the positioning mechanism can be used to perform preliminary positioning of the valve 14, and a support assembly is provided on the fixed seat.

[0023] In this embodiment, the utility model is capable of clamping multiple valves 14 at one time by setting a positioning surface 3, and setting a locking member 4 and a positioning mechanism for fixing the valve 14 on the positioning surface 3. Moreover, through the action of the locking member 4, the positioning mechanism and the supporting assembly, the valve 14 can be accurately positioned and stably fixed, thereby ensuring the quality of processing.

[0024] In an exemplary embodiment, the fixing seat includes a base plate 1 and a mounting block 2 . The mounting block 2 is detachably connected to the base plate 1 , and the positioning surface 3 is located on the mounting block 2 .

[0025] The fixing seat in this embodiment adopts the method of a base plate 1 and a mounting block 2, and the mounting block 2 is fixed on the base plate 1 by means of limiting bolts.

[0026] Exemplarily, a plurality of fixing grooves are provided on the base plate 1, and the fixing grooves are T-shaped grooves. The base of the limiting bolt is a T-shaped block, which can cooperate with the fixing groove and can move freely in the fixing groove along the extension direction of the fixing groove, wherein the limiting bolt is fixed in the fixing groove, and the mounting block 2 is locked by the limiting nut, wherein the mounting block 2 is provided with avoidance grooves for the limiting bolts to enter, and a total of six are provided. Accordingly, the number of limiting bolts is also six. After the limiting bolt enters the limiting groove, it is fixed by the limiting nut. A gasket is provided between the limiting nut and the mounting block 2 to prevent damage to the mounting block 2.

[0027] For example, in this embodiment, the mounting block 2 is an inverted T-shape as a whole, with a thin plate at the bottom connected to the base plate 1, and a rectangular block at the top with four side surfaces and a top surface, which together constitute a positioning surface 3, wherein the four side surfaces and the top surface can fix the valve 14. Therefore, in this solution, five valves 14 can be clamped in one processing.

[0028] It is worth noting that the mounting block 2 in this embodiment can also be of other shapes, and the number of positioning surfaces 3 can be set to be more or less to meet actual processing requirements.

[0029] In an exemplary embodiment, the positioning mechanism includes a positioning rod 7 and a positioning disk 8. The positioning rod 7 is arranged on the positioning surface 3, and the positioning disk 8 is snapped onto the valve 14. The positioning rod 7 passes through the valve 14 and the positioning disk 8 is connected with a fastener 9, and the fastener 9 fixes the positioning disk 8 on the valve 14.

[0030] In this embodiment, the valve 14 can be positioned by the provided positioning rod 7 and positioning plate 8, and after the positioning is completed, the valve 14 is clamped by the locking member 4, thereby effectively improving the accuracy and stability of the locking member 4 in clamping the valve 14. In this embodiment, the positioning plate 8 can cooperate with the valve 14, and its inner end surface can be attached to the valve 14 and supported by the positioning rod 7.

[0031] Illustratively, one end of the positioning rod 7 away from the locking member 4 is threadedly connected to the connecting rod 6, and the connecting rod 6 is detachably connected to the positioning surface 3 by a threaded connection. During installation, after the connecting rod 6 is installed, the positioning rod 7 is installed on the free end of the connecting rod 6. When placing the valve 14, the positioning rod 7 is passed through the valve 14 and then out of the positioning disk 8.

[0032] For example, the positioning plate 8 is provided with a positioning hole, which includes a coarse positioning portion and a fine positioning portion. The coarse positioning portion is a circular hole, and the fine positioning portion is a strip-shaped hole. The circular hole and the strip-shaped hole are connected, and the diameter of the coarse positioning portion is greater than the width of the fine positioning portion. The positioning hole provided in this embodiment allows the positioning plate 8 to be securely fastened to the valve 14 by the fastener 9 after the positioning rod 7 passes through the valve 14 and the positioning plate 8. This simultaneously applies a locking force to the valve 14, causing the valve 14 to fit against the locking member 4. The locking member 4 then locks the valve 14, thereby securing the valve 14. It is worth noting that in this embodiment, the coarse positioning portion is set as a circular hole, and the diameter of the circular hole is larger than the diameter of the positioning rod 7. During positioning, the positioning rod 7 can be passed through the coarse positioning portion first, and then the positioning plate 8 can be moved so that the positioning rod 7 is located at the fine positioning portion, that is, the leftmost end of the strip hole. The width of the strip hole is selected to be slightly larger than the diameter of the positioning rod 7, but smaller than the diameter of the circular hole. After the positioning rod 7 is located at the leftmost end of the strip hole, the fastener 9 is installed to lock the valve 14 on the locking member 4. This installation method allows the positioning rod 7 to pass through the positioning hole more conveniently, and is faster to install.

[0033] In an exemplary embodiment, the locking member 4 is a three-claw chuck, the movable claws of which can move from the inside to the outside to clamp the inner end surface of the valve 14 , and the locking member 4 is detachably connected to the mounting block 2 via a locking bolt 5 .

[0034] In this embodiment, a three-jaw chuck is provided on each positioning surface 3 and is used in conjunction with the positioning mechanism, so that multiple valves 14 can be fixed in one processing process.

[0035] It is worth noting that the three-jaw chuck used in this embodiment can conveniently fix the valve 14. When fixing, the movable clamp is mainly moved from the inside to the outside, and finally the movable clamp is abutted against the inner end face of the valve 14, thereby effectively and stably fixing the valve 14 and preventing the valve 14 from loosening during the processing.

[0036] It should also be noted that in this embodiment, other locking members 4 may be installed on the positioning surface 3 to achieve fixation of the valve 14 .

[0037] In an exemplary embodiment, the support assembly includes a fixing block 10 and a support rod, the support rod is fixedly connected to the fixing block 10, and the fixing block 10 is detachably connected to the base plate 1 via a fixing bolt 11, and the fixing block 10 can rotate around the fixing bolt 11.

[0038] In this embodiment, the support assembly provided can provide support in the vertical direction, thereby improving the fixing effect of the valve 14 .

[0039] For example, in this embodiment, the fixing method of the fixing bolt 11 and the base plate 1 is the same as the limiting bolt, and the support rod is set on the fixing block 10. By moving or rotating the fixing block 10, the support rod can be moved to the specified position so that it contacts the valve 14 and generates a supporting force.

[0040] Illustratively, the support rod includes a fixed rod 12 and a contact rod 13. The fixed rod 12 is fixedly connected to the fixed block 10. One end of the contact rod 13 is disposed on the fixed rod 12, and the free end of the contact rod 13 can abut against the valve 14. The contact rod 13 can support the valve 14. In this embodiment, the contact rod 13 is threaded, so the height of the contact rod 13 can be adjusted by rotating the contact rod 13 to support the valve 14.

[0041] It is worth noting that the support assembly in this embodiment corresponds to the four valves 14 at the bottom, and the valve 14 at the top does not need to be provided with a support assembly due to the support function of the mounting block 2.

[0042] In summary, the present invention can position and clamp multiple valves 14 in one processing process by providing multiple support surfaces, positioning mechanisms and support components, thereby improving the processing efficiency of the valves 14 while ensuring processing accuracy.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
