Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of valve body machining, and more specifically, to a rotary tooling for valve body machining. Background Technology
[0002] In the field of valve body machining, rotary tooling is a key piece of equipment for achieving precise positioning and efficient machining of valve bodies. Its adaptability to different valve body shapes directly affects machining efficiency and production costs. However, traditional rotary tooling for valve body machining generally suffers from the problem of not being able to adjust the support and fixing position according to different valve body shapes. This leads to the need for frequent tooling changes when machining valve bodies of different specifications, which not only increases the workload of operators but also seriously affects the continuity of production.
[0003] Existing rotary tooling mostly uses fixed support structures, with pre-designed support positions and fixing methods, making it difficult to adapt to the diverse shapes of valve bodies. When dealing with valve bodies of different diameters and structures, fixed support structures cannot accurately match the support requirements of the valve body, easily causing unstable fixing or uneven stress in certain areas, affecting machining accuracy. For example, when machining valve bodies with significant differences in shape, such as ball valves and gate valves, traditional tooling requires complete disassembly and replacement of suitable support components. The entire process is time-consuming and labor-intensive, and frequent tooling changes lead to a decrease in equipment accuracy and increased maintenance costs.
[0004] Meanwhile, traditional rotary tooling lacks a flexible adjustment mechanism, preventing operators from adjusting the support and fixing positions in real time according to the valve body's shape. For irregularly shaped valve bodies or non-standard parts, the applicability of traditional tooling is even worse, often requiring customized tooling, further increasing production costs and time. Furthermore, frequent tooling changes lead to extended production line downtime, reduced production efficiency, and difficulty in meeting the demands of modern mass production.
[0005] With the increasing variety of valve bodies and growing demand for personalization in industrial production, traditional rotary tooling is no longer able to meet the diverse valve body processing needs due to problems such as "inconvenient adjustment, poor adaptability, and frequent replacement". Utility Model Content
[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a rotary tooling for valve body machining, which solves the technical problem that existing rotary tooling for valve body machining generally cannot adjust the support and fixing position according to different valve body shapes.
[0007] According to one aspect, at least one embodiment of this disclosure provides a rotary tooling for machining valve bodies, comprising:
[0008] A support platform and a rotating frame, wherein the rotating frame is slidably connected to the support platform;
[0009] The system includes several bases and an adjustment assembly, wherein the bases are all fixed on the rotating frame, and the adjustment assembly is disposed between the bases and the rotating frame.
[0010] The drive motor and the fixing clamping assembly are provided. The drive motor is located at the bottom of the support platform and its output end is connected to the rotating frame. The fixing clamping assembly is located on the base.
[0011] The fixing clamping assembly includes a slide rail, which is disposed on the base. A movable seat is slidably connected to the slide rail, and a telescopic cylinder is installed on the movable seat. A pressure block is provided at the output end of the telescopic cylinder.
[0012] As a further technical solution, a rack is provided on the outer side of the slide rail, a connecting frame is telescopically connected to the side end face of the movable seat, a stud is rotatably connected inside the connecting frame, and one end of the stud is connected to the movable seat by a threaded engagement.
[0013] As a further technical solution, the bottom of the movable seat is provided with a locking block, which is embedded in the rack. The bottom of the connecting frame is provided with an outer pulley, and the bottom of the movable seat is provided with an inner pulley. The inner pulley and the outer pulley are respectively attached to the inner and outer sides of the slide rail.
[0014] As a further technical solution, the adjustment component includes several rectangular slots, all of which are formed on the surface of the rotating frame. An adjustment screw is rotatably connected in the rectangular slot, and the movable seat is slidably connected in the rectangular slot. The movable seat and the adjustment screw are connected by a threaded engagement.
[0015] As a further technical solution, the surface of the pressure block is provided with an anti-slip raised layer.
[0016] As a further technical solution, the side end face of the card block has a toothed structure, and the card block matches the rack structure.
[0017] As a further technical solution, several of the telescopic cylinders are distributed in a cross-shaped pattern.
[0018] As a further technical solution, a screw block is provided at one end of the stud, and the screw block has a polygonal structure.
[0019] The beneficial effects of the embodiments disclosed herein are as follows:
[0020] 1. In this disclosure, the fixed clamping assembly achieves smooth sliding of the moving seat through the slide rail and inner and outer pulleys. The toothed structure of the locking block and the rack meshes to achieve precise positioning and rigid locking. The stud adjusts the engagement and disengagement of the locking block and the rack. The telescopic cylinder drives the pressure block to clamp the valve body from different directions. The anti-slip protrusion increases the friction. The cross-shaped telescopic cylinder is suitable for fixing different parts, solving the problem that traditional tooling cannot flexibly adjust the support and fixing position, realizing reliable fixing of valve bodies with different shapes, and reducing the frequency of tooling replacement.
[0021] 2. In this disclosure, the adjusting component slides between the rectangular groove and the movable seat through the sliding engagement of the adjusting screw. The screw drive drives the movable seat to slide laterally within the rectangular groove, precisely adjusting the position of the base on the rotating frame. This adapts to the clamping requirements of valve bodies of different sizes. For large valve bodies, the base spacing can be increased to support multiple points, while for small valve bodies, the spacing can be reduced to enhance support rigidity. This expands the applicability of the tooling, avoids frequent tooling changes when processing valve bodies of different specifications, and improves production continuity and efficiency.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0034] like Figures 1-4 As shown, a rotary tooling for valve body machining is illustrated in one embodiment of this disclosure, comprising:
[0035] A support platform 1 and a rotating frame 2, wherein the rotating frame 2 is slidably connected to the support platform 1;
[0036] A plurality of bases 3 and an adjustment component 6, wherein the bases 3 are all fixed on the rotating frame 2, and the adjustment component 6 is disposed between the bases 3 and the rotating frame 2;
[0037] The drive motor 4 and the fixing clamping assembly 5 are provided. The drive motor 4 is located at the bottom of the support platform 1, and the output end of the drive motor 4 is connected to the rotating frame 2. The fixing clamping assembly 5 is located on the base 3.
[0038] The fixing clamping assembly 5 includes a slide rail 5-1, which is mounted on the base 3. A movable seat 5-2 is slidably connected to the slide rail 5-1. A telescopic cylinder 5-3 is mounted on the movable seat 5-2. A pressure block 5-4 is provided at the output end of the telescopic cylinder 5-3. A rack 5-5 is provided on the outer side of the slide rail 5-1. A connecting frame 5-6 is telescopically fitted to the side end face of the movable seat 5-2. A stud 5-7 is rotatably fitted inside the connecting frame 5-6. One end of the stud 5-7 is threadedly connected to the movable seat 5-2. A locking block 5-8 is provided at the bottom of the movable seat 5-2 and is embedded in the rack 5-5. An outer pulley 5-9 is provided at the bottom of the connecting frame 5-6. An inner pulley 5-10 is provided at the bottom of the movable seat 5-2. The inner pulley 5-10 and the outer pulley 5-9 are respectively attached to the inner and outer sides of the slide rail 5-1.
[0039] In some examples, a fixing clamping assembly 5 is designed to achieve flexible fixation of the valve body in multiple positions. This assembly is guided by the slide rail 5-1 on the base 3. The moving seat 5-2 slides smoothly by the inner pulley 5-10 and the outer pulley 5-9 adhering to the inner and outer sides of the slide rail 5-1. The engagement of the bottom locking block 5-8 with the rack 5-5 can accurately position the moving seat 5-2. When the rotating polygonal screw block drives the stud 5-7 to rotate, the locking block 5-8 can be separated from the rack 5-5. After separation, the moving seat 5-2 can move freely along the slide rail 5-1 with the help of the telescopic guide of the connecting frame 5-6. After adjusting to the target position, the stud is screwed in the opposite direction so that the locking block 5-8 is embedded in the tooth groove of the rack 5-5 to achieve rigid locking. The pressure block 5-4 at the output end of the telescopic cylinder 5-3 can be controlled by the coordinated action of multiple sets of cylinders distributed in a cross shape when the cylinder piston rod extends. The pressure block 5-4 can be controlled to press against the valve body from different directions such as horizontal and vertical, adapting to the fixing requirements of different parts such as flanges and valve stems. Its surface anti-slip convex layer can effectively enhance the friction during clamping.
[0040] Through the guide support of slide rail 5-1 and pulley, the positioning and locking of rack 5-5 and locking block 5-8, the displacement adjustment of stud 5-7 and the pressure application of cylinder, the fixing clamping assembly 5 can reliably fix the valve body in multiple positions by adjusting the position of moving seat 5-2 and the extension and retraction of cylinder.
[0041] like Figures 1-4 As shown in the figure, the adjustment component 6 in this embodiment includes a plurality of rectangular slots 6-1, all of which are formed on the surface of the rotating frame 2. An adjustment screw 6-2 is rotatably connected in the rectangular slot 6-1, and a movable seat 5-2 is slidably connected in the rectangular slot 6-1. The movable seat 5-2 and the adjustment screw 6-2 are connected by a threaded engagement.
[0042] In some examples, an adjustment assembly 6 is designed to accommodate the clamping requirements of valve bodies of different sizes. This assembly uses a rectangular groove 6-1 on the surface of the rotating frame 2 as its mounting base. The adjusting screw 6-2 passes through the movable seat 5-2 and is threaded into it. Rotating the screw drives the movable seat 5-2 to slide laterally within the rectangular groove 6-1, thereby adjusting the position of the base 3 on the rotating frame 2. The slider at the bottom of the movable seat 5-2 engages with the guide rail on the inner wall of the rectangular groove 6-1 to ensure smooth and wobbly movement. The spacing of the base 3 can be increased to support multiple points; for small valve bodies, reducing the spacing can enhance the support rigidity.
[0043] By adjusting the threaded drive of the screw 6-2, the guiding fit between the rectangular groove 6-1 and the slider, and the precise positioning of the scale line, the adjustment component 6 can flexibly adjust the position of the base 3 according to the overall size of the valve body, thus expanding the applicability of the tooling.
[0044] For example, such as Figure 1 As shown, the surface of the pressure block 5-4 is provided with an anti-slip raised layer 7.
[0045] In some examples, the anti-slip raised layer 7 is provided to increase the friction with the cylinder surface, further enhancing the clamping firmness.
[0046] For example, such as Figure 4 As shown, the side end face of the locking block 5-8 has a toothed structure, and the locking block 5-8 matches the structure of the rack 5-5.
[0047] In some examples, the toothed structure allows for a firm and stable fixation after the locking block 5-8 engages with the rack 5-5, preventing any loosening.
[0048] For example, such as Figure 1 As shown, several of the telescopic cylinders 5-3 are distributed in a cross shape.
[0049] In some examples, the distribution of cross-shaped points ensures that the multiple telescopic cylinders 5-3 are more evenly distributed, preventing situations where they cannot be supported and fixed.
[0050] For example, such as Figure 2 As shown, a screw block 8 is provided at one end of the stud 5-7, and the screw block 8 has a polygonal structure.
[0051] In some examples, control is achieved by manually turning the studs 5-7 using a polygonal screw block 8.
[0052] In practical use: the support platform 1 is fixed to the processing platform with anchor bolts. The rotating frame 2 is slidably connected to the support platform 1 via the bottom guide rail. The base 3 is evenly fixed around the circumference of the rotating frame 2. The rectangular groove 6-1 of the adjusting component 6 is opened on the surface of the rotating frame 2 and extends radially. The adjusting screw 6-2 is rotatably connected to the rectangular groove 6-1 via a bearing seat. The knob at its outer end can be manually turned. The adjusting screw 6-2 is threadedly engaged with the nut seat at the bottom of the movable seat 5-2. The drive motor 4 is installed at the bottom of the support platform 1 via a shock-absorbing base. The output shaft is connected to the central rotating shaft of the rotating frame 2 via a coupling. The slide rail 5-1 of the fixing clamping component 5 is welded to the top surface of the base 3. The inner pulley 5-10 and outer pulley 5-9 at the bottom of the movable seat 5-2 respectively fit against the inner and outer groove walls of the slide rail 5-1. The locking block 5-8 is hinged to the bottom of the movable seat 5-2 via a spring pin. The toothed end face meshes with the rack 5-5. The stud 5-7 passes through the guide hole of the connecting frame 5-6 and mates with the threaded hole on the side wall of the moving seat 5-2. The telescopic cylinder 5-3 is vertically installed on the top surface of the moving seat 5-2. The pressure block 5-4 is connected to the cylinder piston rod through the threaded post and has anti-slip texture pressed on its surface. When in use, first rotate the adjusting screw 6-2 to move the base 3 laterally in the rectangular groove 6-1 and adjust it to the support spacing that matches the valve body diameter. Then rotate the stud 5-7 to drive the locking block 5-8 to disengage from the rack 5-5. Push the moving seat 5-2 along the slide rail 5-1 to the top of the valve body to be clamped. Twist the stud in the opposite direction to make the locking block 5-8 embed into the tooth groove of the rack 5-5 and lock it in place. Start the telescopic cylinder 5-3 to make the pressure block 5-4 press against the valve body from all four sides. Finally, drive the motor 4 to drive the rotating frame 2 to rotate at the set speed, and complete the multi-face processing of the valve body with the help of the processing equipment.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
