Description

Technical Field

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

[0002] In the field of machining, the valve body is a key component of fluid control, and its machining accuracy directly affects the operating performance of the equipment.

[0003] refer to Figure 1 As shown, there is a conventional valve body 01. The valve body 01 is provided with valve ports that extend through its left and right sides. The upper side of the valve body 01 is provided with a mounting plane 02, and the center of the mounting plane 02 is provided with a connecting hole 03 for connecting the valve stem.

[0004] When machining the connection hole 03, it is necessary to ensure that the connection hole 03 is perpendicular to the mounting plane 02. This is an important prerequisite for ensuring the assembly accuracy and functionality of the valve body.

[0005] In existing technology, when machining the connecting hole 03, the valve body 01 must first be fixed, and then the mounting plane 02 must be kept horizontal through measurement and calibration before the connecting hole 03 can be machined. However, this machining method has obvious shortcomings. On the one hand, fixing the valve body 01 is a cumbersome process, requiring multiple adjustments to the fixing device, which consumes a lot of time and manpower. On the other hand, measuring and calibrating the horizontal position of the mounting plane 02 relies on manual operation and measuring tools, which is not only inefficient but also easily affected by human and environmental factors, leading to errors in the measurement and calibration results. It is difficult to quickly and accurately keep the mounting plane 02 in a horizontal position, which in turn affects the perpendicularity of the connecting hole 03 to the mounting plane 02, reducing the machining accuracy and production efficiency of the valve body.

[0006] Therefore, how to quickly and accurately fix the valve body 01 and ensure that the mounting plane 02 remains horizontal has become a technical problem that needs to be solved. Utility Model Content

[0007] In view of the problems pointed out in the background art, this utility model proposes a valve body mounting platform machining fixture to solve the above-mentioned technical problems.

[0008] The technical solution of this utility model is implemented as follows:

[0009] A valve body mounting platform processing fixture includes a fixed plate, the upper side of which is provided with a horizontal calibration surface, and also includes a calibration groove penetrating the front and rear sides and the upper side of the fixed plate. The calibration groove has a square cross-section, and the lower side of the calibration groove is parallel to the horizontal calibration surface. The front side of the fixed plate is provided with a fixing mechanism for fixing the valve body, and also includes a calibration strip with a square cross-section that is adapted to the calibration groove.

[0010] The present invention is further configured such that the fixing plate is circular, and the calibration groove is located in the middle of the fixing plate.

[0011] The present invention is further provided that a fixing part is provided on the rear side of the fixing plate.

[0012] The present invention is further configured such that a positioning plate is provided on the front side of the fixed plate, and the positioning plate is coaxially arranged with the fixed plate.

[0013] The present invention is further configured such that the fixing mechanism includes a plurality of screws arranged circumferentially along the fixing disc, and a pressure plate and a nut are connected to the screws.

[0014] The present invention is further configured such that the fixing part is coaxially arranged with the fixing disk.

[0015] The present invention is further configured such that the positioning disk is circular.

[0016] The present invention is further configured such that the fixed plate is provided with a threaded hole for connection with the screw.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0018] The valve body mounting platform and machining fixture provided by this utility model first fixes the fixing plate, ensuring that its horizontal alignment surface is level. Then, the valve body is fixedly mounted on the fixing plate. During valve body installation, the alignment strip is placed in the alignment groove, with its lower side level. As long as the mounting plane of the valve body mates with the lower side of the alignment strip, the valve body can be fixed, and its mounting plane will be level. This allows for quick clamping and fixing of the valve body, improving machining efficiency and achieving high machining accuracy. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] For reference as follows Figures 1-5 The present invention will be described as follows:

[0028] Example: A valve body mounting platform machining fixture includes a fixed plate 1, which is circular. The fixed plate 1 serves as the basic load-bearing component of the fixture, and its circular structure helps maintain overall balance during installation.

[0029] The upper side of the fixed plate 1 is provided with a horizontal alignment surface 2, which serves as a horizontal reference surface during tooling installation. The setting of the horizontal alignment surface 2 provides a clear horizontal reference standard for the entire tooling. By calibrating the surface of the fixed plate 1 during installation, it can be ensured that the fixed plate 1 is in a horizontal state.

[0030] It also includes a calibration groove 3 that runs through the front, back, sides and top of the fixed plate 1. The calibration groove 3 is located on the top of the fixed plate 1. The cross-section of the calibration groove 3 is square (the calibration groove 3 is a U-shaped structure with an upward opening). The calibration groove 3 is located in the middle of the fixed plate 1. The lower side of the calibration groove 3 is parallel to the horizontal calibration surface 2.

[0031] The calibration slot 3 is positioned in the middle of the fixed plate 1, ensuring that its lower side is also horizontal when the fixed plate 1 is horizontal. Furthermore, its parallelism with the horizontal calibration plate 2 further guarantees the accuracy of the lower side's horizontal alignment. The upward-facing U-shaped opening of the calibration slot 3 facilitates the insertion and removal of the calibration strip 4.

[0032] The front side of the fixed plate 1 is provided with a fixing mechanism for fixing the valve body 01, which secures the valve body 01 to the fixed plate 1. The main function of the fixing mechanism is to firmly fix the valve body 01 to the fixed plate 1. In actual operation, fixing the valve body 01 by the fixing mechanism can prevent the valve body 01 from shifting during processing, ensuring the stability and accuracy of processing.

[0033] It also includes a calibration strip 4 with a square cross-section that fits the calibration groove 3. This means that the calibration strip 4 can be tightly inserted into the calibration groove 3. When the calibration strip 4 is inserted into the calibration groove 3, since the lower side of the calibration groove 3 is horizontal, the lower side of the calibration strip 4 is also horizontal, and this lower side can be used as a reference surface for the horizontal mounting plane 02 of the calibration valve body 01.

[0034] When using this fixture, first, fix the mounting plate 1 in place. During installation, use measuring tools (such as a level) to check and adjust the leveling surface 2 to ensure it is level. Since the lower side of the calibration groove 3 is parallel to the leveling surface 2, the lower side of the calibration groove 3 will also be level. Next, place the calibration strip 4 into the calibration groove 3. Because the two fit together, the lower side of the calibration strip 4 will be in contact with or parallel to the lower side of the calibration groove 3, thus keeping the lower side of the calibration strip 4 level as well.

[0035] Then, the valve body 01 is installed and fixed. The valve body 01 is placed on the front side of the fixing plate 1, so that the mounting surface 02 of the valve body 01 is in contact with the lower side of the calibration strip 4. Since the lower side of the calibration strip 4 is horizontal, when the mounting surface 02 is in contact with this surface, it can be determined that the mounting surface 02 is in a horizontal position. At this time, the valve body 01 is fixed to the fixing plate 1 by the fixing mechanism, completing the clamping of the valve body 01.

[0036] Beneficial Effects: This fixture, through the coordinated action of the fixed plate 1, the horizontal alignment surface 2, the alignment groove 3, the alignment strip 4, and the fixing mechanism, achieves rapid fixation of the valve body 01 and accurate correction of the horizontal position of the mounting plane 02. Compared with existing technologies, it eliminates the need for repeated measurement and correction of the valve body 01, reducing manual operation steps and mitigating the impact of human and environmental factors on the correction results. Through the structural design of the fixture, utilizing the parallel relationship between the horizontal alignment surface 2 and the alignment groove 3, and the fitting relationship between the alignment strip 4 and the alignment groove 3, the horizontal accuracy of the lower side of the alignment strip 4 is ensured. This allows for the rapid and accurate leveling of the mounting plane 02 of the valve body 01, improving the efficiency and accuracy of valve body 01 clamping and fixing. Furthermore, it ensures the perpendicularity of the connecting hole 03 to the mounting plane 02, enhancing the machining accuracy and production efficiency of the valve body 01.

[0037] A fixing part 5 is provided on the rear side of the fixed plate 1, and the fixing part 5 is coaxially arranged with the fixed plate 1. The shape and size of the fixing part 5 are adapted to the chuck or other fixing devices on the machine tool. The main function of the fixing part 5 is to connect and fix the tooling to the machine tool or other fixing devices. By fixing the fixing part 5 to the chuck on the machine tool, the entire tooling can be stably installed on the machine tool, ensuring that the tooling remains stable during machining. This coaxial arrangement ensures that the central axis of the fixing part 5 is aligned with that of the fixed plate 1, thereby ensuring that the fixed plate 1 remains horizontal after installation, providing a stable foundation for subsequent machining operations.

[0038] A positioning disc 6 is provided on the front side of the fixed disc 1. The positioning disc 6 is circular and coaxially arranged with the fixed disc 1. The diameter of the positioning disc 6 is equal to the diameter of the valve port of the valve body 01. The valve body 01 is sleeved on the positioning disc 6 on the fixed disc 1, and the positioning disc 6 radially fixes the valve body 01. The fixing mechanism axially fixes the valve body 01.

[0039] When the valve body 01 is fitted onto the positioning plate 6, the outer circular surface of the positioning plate 6 mates with the inner circular surface of the valve port of the valve body 01, thereby radially fixing the valve body 01. This radial fixing method can accurately limit the radial movement of the valve body 01, ensuring the accurate radial position of the valve body 01 on the fixing plate 1. Since the positioning plate 6 and the fixing plate 1 are coaxial, after the valve body 01 is fitted, its central axis coincides with the central axis of the fixing plate 1, providing a good basis for the subsequent machining of the perpendicularity of the connecting hole 03 and the mounting plane 02.

[0040] The fixing mechanism consists of multiple screws 7 arranged circumferentially along the fixing plate 1, pressure plates 8 connected to the screws 7, and nuts 9. The fixing plate 1 has threaded holes 10 for connecting to the screws 7, and the screws 7 are connected to the fixing plate 1 through the threaded holes 10. When it is necessary to fix the valve body 01, the valve body 01 is sleeved on the positioning plate 6, so that the mounting plane 02 of the valve body 01 is in contact with the lower side of the calibration strip 4 (at this time, the mounting plane 02 is in a horizontal state). Then, the pressure plate 8 is placed on the valve body 01 at the position corresponding to the screw 7, and the nut 9 is rotated to move on the screw 7. As the nut 9 is tightened, the pressure plate 8 gradually presses the valve body 01 downward, thereby achieving axial fixation of the valve body 01. This axial fixing method can effectively prevent the valve body 01 from moving in the vertical direction (i.e., axial direction), ensuring that the valve body 01 remains stable during processing.

[0041] The design of multiple screws 7 arranged circumferentially along the fixed plate 1 ensures that the pressure plate 8 can evenly press the valve body 01, preventing deformation or insecure fixing of the valve body 01 due to excessive or insufficient local pressure. By adjusting the tightness of each nut 9, the pressure plate 8 can apply uniform pressure to the valve body 01, ensuring that the valve body 01 is accurately and stably positioned on the fixed plate 1.

[0042] The fixing part 5, the positioning plate 6, and the fixing mechanism work together to fix and position the valve body 01. The fixing part 5 securely mounts the fixture on the machine tool, ensuring the stability of the entire fixture; the positioning plate 6 radially fixes the valve body 01, determining its radial position; the fixing mechanism axially fixes the valve body 01 through the cooperation of the pressure plate 8 and the nut 9, preventing the valve body 01 from moving axially.

[0043] In actual operation, the tooling is first installed on the machine tool using the fixing part 5, ensuring that the horizontal alignment surface 2 of the fixing plate 1 is horizontal. Then, the valve body 01 is fitted onto the positioning plate 6, which radially positions the valve body 01. Next, the valve body 01 is axially fixed using the screw 7, pressure plate 8, and nut 9 of the fixing mechanism, firmly mounting the valve body 01 onto the fixing plate 1. This fixing and positioning method allows for quick and accurate fixation of the valve body 01 onto the fixing plate 1, ensuring that the mounting plane 02 of the valve body 01 is horizontal. This provides an accurate reference for the subsequent machining of the connecting hole 03, ensuring that the connecting hole 03 is perpendicular to the mounting plane 02, thus improving the machining accuracy and production efficiency of the valve body 01.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
