Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a valve body fixture. Background Technology

[0002] The basic shape of a valve body is hexagonal. Depending on the application and function, the design features of each face of the valve body vary, resulting in variations in size and length. Consequently, there are many types of valve bodies, and most are produced primarily for prototyping and small-batch processing, leading to frequent production changes. Currently, valve body processing in the industry mainly involves fixing the valve body in a vise, then machining one face using a processing device. The vise is then released, the valve body is repositioned, and the vise is used again to fix it, repeating this process to machine all six faces. Ultimately, valve body processing requires six clamping operations, which consumes significant time and negatively impacts production efficiency and equipment uptime.

[0003] The prior art CN201711069067.0 discloses a valve body clamp for clamping and processing valve bodies, including a clamping body. The clamping body includes a base and a side frame. A support plate is fixed on the base. The side frame is provided with a positioning pin for fixing the valve body in the horizontal direction. A template is fixed to the top of the side frame by screws. A clamping screw is provided on the template. A smooth pressure block is provided between the clamping screw and the valve body. A drill sleeve is also provided on the template. A drill sleeve screw is provided inside the drill sleeve. A bushing is also provided between the drill sleeve and the drill sleeve screw.

[0004] The valve body fixtures disclosed in the existing technology can only fix the valve body, and cannot solve the problem of low valve body processing efficiency caused by frequent clamping during the valve body processing. Utility Model Content

[0005] The technical problem solved by this utility model is to overcome the problems existing in the prior art and provide a valve body fixture that improves the processing efficiency of valve bodies.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A valve body clamp is disclosed. The clamp includes a base, a four-axis turntable disposed on the base, a bridge plate connecting the two ends of the four-axis turntable, and a clamping block connected to the bridge plate. The clamping block includes a first fixing block and a second fixing block located on both sides of the valve body, and a sliding block that slides up and down relative to the side surface of the second fixing block. The sliding block is connected to the bridge plate by bolts. The first fixing block and the sliding block clamp the valve body.

[0008] Preferably, the four-axis turntable includes a first turntable with a rotating shaft under the action of a motor, and a second turntable disposed on the tailstock, with the first turntable and the second turntable respectively connected to both ends of the bridge plate.

[0009] Preferably, the bridge plate is further provided with a positioning plate for fixing the clamping block, and the positioning plate is connected to the bridge plate by bolts.

[0010] Preferably, the positioning plate is further provided with precision holes.

[0011] Preferably, a rack is also provided on the surface of the positioning plate that contacts the clamping block. This design improves the stability between the clamping block and the positioning plate and prevents the clamping block from sliding.

[0012] Preferably, a size strip is also engraved on the side surface of the positioning plate. This allows for the installation of corresponding clamping blocks to match the valve body dimensions, improving the assembly efficiency of the device.

[0013] Preferably, two positioning plates are provided on the same surface of the bridge plate.

[0014] Preferably, positioning plates are provided on both the upper and lower surfaces of the bridge plate.

[0015] Preferably, the positioning plate is provided with four sets of clamping blocks.

[0016] Preferably, an extension plate is also provided between the base and the four-axis rotary table. By designing the extension plate, the machining of valve bodies of different sizes can be further accommodated.

[0017] Compared with existing technologies, it has the following beneficial effects:

[0018] 1) The bridge plate is driven to rotate by a four-axis rotary table, which in turn drives the valve body fixed on the bridge plate to rotate. Through rotation, the three sides of the valve body can be machined, reducing the number of clamping operations and thus reducing the clamping time, thereby improving the machining efficiency of the valve body.

[0019] 2) Multiple sets of clamping blocks can be set on the bridge plate, which can clamp multiple valve bodies and further improve the processing efficiency of valve bodies. Attached Figure Description

[0028] Example 1

[0029] like Figures 1 to 3 As shown, a valve body clamp is disclosed. The clamp specifically includes a base 1, a four-axis turntable 2 disposed on the base 1, a bridge plate 3 connecting the two ends of the four-axis turntable 2, and a clamping block connected to the bridge plate 3. The clamping block includes a first fixing block 4 and a second fixing block 5 located on both sides of the valve body 7, and a sliding block 6 that slides up and down relative to the side surface of the second fixing block 5. The sliding block 6 is connected to the bridge plate 3 by bolts. The first fixing block 4 and the sliding block 6 clamp the valve body 7.

[0030] In this embodiment, the base 1 serves as a support platform, specifically the workbench of a processing equipment (drilling rig). The four-axis rotary table 2 is fixed to the base 1, specifically, the four-axis rotary table 2 and the base 1 can be fixedly connected by bolts or other means. The two ends of the four-axis rotary table 2 are connected by bridge plates 3. When the four-axis rotary table 2 moves, it will synchronously drive the bridge plates 3 to rotate. Clamping blocks are provided on the bridge plates 3. The clamping blocks specifically include a first fixing block 4 and a second fixing block 5 located on both sides of the valve body 7, and also include a sliding block 6 that can slide up and down relative to the side surface of the second fixing block 5 facing the valve body. Specifically, the second fixing block 5 and the sliding block 6 can be set in a trapezoidal shape, and the intersecting surface of the two is a trapezoidal inclined surface.

[0031] Before fixing the clamping blocks, first confirm the dimensions of the valve body 7 to ensure the correct installation of the first fixing block 4 and the second fixing block 5. During valve body 7 installation, the left side of the valve body 7 abuts against the side surface of the first fixing block 4 located on the left side of the valve body 7. Then, control the sliding block 6 to slide up and down along the inclined surface of the second fixing block 5. Finally, the left side of the sliding block 6 abuts only against the right side of the valve body 7. At this point, the sliding block 6 is fixed to the bridge plate 3 using bolts or other methods. Ultimately, both sides of the valve body 7 are completely abutted, thus achieving clamping and fixing of the valve body 7.

[0032] After one surface of the valve body 7 is machined, the four-axis rotary table 2 is started, which drives the bridge plate 3 to rotate, thereby switching the second surface of the valve body 7 to be machined to the processing area of ​​the processing equipment, waiting for processing.

[0033] The four-axis rotary table 2 drives the valve body 7 to rotate. Each time the valve body 7 is clamped, it is rotated to process the three sides of the valve body 7, which greatly reduces the number of clamping operations of the valve body 7 and thus improves the processing efficiency of the valve body 7.

[0034] Example 2

[0035] A valve body clamp is disclosed. The clamp specifically includes a base 1, a four-axis turntable 2 mounted on the base 1, a bridge plate 3 connecting the two ends of the four-axis turntable 2, and a clamping block connected to the bridge plate 3. The clamping block includes a first fixing block 4 and a second fixing block 5 located on both sides of the valve body 7, and a sliding block 6 that slides up and down relative to the side surface of the second fixing block 5. The sliding block 6 is connected to the bridge plate 3 by bolts. The first fixing block 4 and the sliding block 6 clamp the valve body 7.

[0036] The difference between this embodiment and Embodiment 1 is that the four-axis rotary table 2 can specifically adopt an industry-existing CNC-320R. Specifically, it includes a base, a motor mounted on the base, and the motor's output shaft connected to a first turntable 20. It also includes a tailstock and a second turntable 21 mounted on the tailstock. The first turntable 20 and the second turntable 21 face each other and are spaced apart. A bridge plate 3 connects the first turntable 20 and the second turntable 21; when the motor starts, it drives the bridge plate 3 to rotate.

[0037] Example 3

[0038] A valve body clamp is disclosed. The clamp specifically includes a base 1, a four-axis turntable 2 mounted on the base 1, a bridge plate 3 connecting the two ends of the four-axis turntable 2, and a clamping block connected to the bridge plate 3. The clamping block includes a first fixing block 4 and a second fixing block 5 located on both sides of the valve body 7, and a sliding block 6 that slides up and down relative to the side surface of the second fixing block 5. The sliding block 6 is connected to the bridge plate 3 by bolts. The first fixing block 4 and the sliding block 6 clamp the valve body 7.

[0039] The difference between this embodiment and Embodiment 1 is that, to facilitate the installation of the clamping block, a positioning plate 8 can be provided on the bridge plate 3, and the clamping block can be fixed on the positioning plate 8. Specifically, the clamping block and the positioning plate 8 can be connected by bolts.

[0040] Meanwhile, in order to ensure the machining accuracy of the valve body 7, corresponding precision holes are also provided on the positioning plate 8 and the bridge plate 3.

[0041] In this embodiment, the valve body 7 will vibrate during processing, causing the clamping block to slide. Therefore, a rack is provided on the upper surface of the positioning plate 8 that contacts the clamping block, and a rack is also provided on the lower surface of the clamping block that holds the positioning plate 8. By adding a meshing connection between the clamping block and the positioning plate 8, it is ensured that the valve body 7 will not slide relative to each other during processing, thus ensuring the processing accuracy and quality of the valve body 7.

[0042] Example 4

[0043] A valve body clamp is disclosed. The clamp specifically includes a base 1, a four-axis turntable 2 mounted on the base 1, a bridge plate 3 connecting the two ends of the four-axis turntable 2, and a clamping block connected to the bridge plate 3. The clamping block includes a first fixing block 4 and a second fixing block 5 located on both sides of the valve body 7, and a sliding block 6 that slides up and down relative to the side surface of the second fixing block 5. The sliding block 6 is connected to the bridge plate 3 by bolts. The first fixing block 4 and the sliding block 6 clamp the valve body 7.

[0044] The difference between this embodiment and embodiment 3 is that a size strip is provided on the side surface of the positioning plate 8. During installation, the clamp can be quickly installed according to the dimensions of the valve body 7, ensuring that the clamp effectively secures the valve body 7. This design greatly improves the installation efficiency of the clamp.

[0045] Example 5

[0046] A valve body clamp is disclosed. The clamp specifically includes a base 1, a four-axis turntable 2 mounted on the base 1, a bridge plate 3 connecting the two ends of the four-axis turntable 2, and a clamping block connected to the bridge plate 3. The clamping block includes a first fixing block 4 and a second fixing block 5 located on both sides of the valve body 7, and a sliding block 6 that slides up and down relative to the side surface of the second fixing block 5. The sliding block 6 is connected to the bridge plate 3 by bolts. The first fixing block 4 and the sliding block 6 clamp the valve body 7.

[0047] The difference between this embodiment and embodiment 3 is that, in order to further improve the processing efficiency of the valve body, two positioning plates 8 can be set on the same surface of the bridge plate 3, and each positioning plate 8 is provided with a clamping block.

[0048] Additionally, a positioning plate 8 can also be provided on the lower surface of the bridge plate 3. Specifically, two positioning plates 8 can also be provided.

[0049] Alternatively, four sets of clamping blocks can be installed on the positioning plate 8. When four sets of clamping blocks are designed, the second fixing block 5 in the first set of clamping blocks can be used as the first fixing block 4 in the second set of clamping blocks. This design reduces the manufacturing cost of this fixture.

[0050] The above design greatly improves the uptime of the processing equipment, thereby further improving the processing efficiency of the valve body.

[0051] Example 6

[0052] A valve body clamp is disclosed. The clamp specifically includes a base 1, a four-axis turntable 2 mounted on the base 1, a bridge plate 3 connecting the two ends of the four-axis turntable 2, and a clamping block connected to the bridge plate 3. The clamping block includes a first fixing block 4 and a second fixing block 5 located on both sides of the valve body 7, and a sliding block 6 that slides up and down relative to the side surface of the second fixing block 5. The sliding block 6 is connected to the bridge plate 3 by bolts. The first fixing block 4 and the sliding block 6 clamp the valve body 7.

[0053] The difference between this embodiment and the previous embodiment is that when the valve body 7 is too large, the distance between the first turntable 20 and the second turntable 21 needs to be increased to ensure that four valve bodies 7 can be clamped at once. However, the size of the processing table of the processing equipment is fixed, which means that the four-axis turntable 2 cannot be properly installed on the processing table. To avoid this problem, an extension plate 9 can be set on the processing table, and the four-axis turntable 2 is fixed on the extension plate 9. Through this design, the installation and fixation of the four-axis turntable 2 can be satisfied, thus making this fixture suitable for processing valve bodies of different sizes.

[0054] Obviously, the above embodiments are merely examples to clearly illustrate the technical solution of this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
