Description

Technical Field

[0001] This utility model relates to the field of valve parts processing technology, specifically to a high-precision machine tool for processing valve parts. Background Technology

[0002] High-precision machining tools for valve parts are specifically designed for the precision manufacturing of valve components. Equipped with an advanced CNC system, they precisely control the tool's movement trajectory, enabling the machining of complex curved surfaces. High-precision spindles and transmission components ensure stability and reliability in the machining process, minimizing machining errors. Suitable for valve parts made of various materials, they allow for one-time forming from blank to finished product, significantly improving production efficiency. The machined parts are dimensionally accurate and have smooth surfaces, making them widely used in industries such as petroleum, chemical, and power, providing a solid guarantee for high-quality valve manufacturing. However, existing machining tools still have certain problems in use:

[0003] For example, a high-precision CNC machine tool for machining parts, as described in application number 202111484264.5, comprises: a machine tool body, a machining device located inside the machine tool body, a first cutting fluid storage tank located below the machining device, a filtration device located inside the first cutting fluid storage tank, and a control device; the filtration device includes a chip removal component, a cutting fluid filtration component, an air jet component, a filtration and cleaning component, and a first control component located at the top inside the first cutting fluid storage tank; the inclusion of the chip removal component and the cutting fluid filtration component allows for better filtration and removal of chips from the cutting fluid. In addition, a filter cleaning component is installed to clean the cutting fluid filter component, which can better ensure the filtering effect of chips; an air jet component is installed, but the existing parts processing machine tools have insufficient stable clamping ability for valve parts. Due to the different shapes of valve parts, the existing machine tool clamping device has poor versatility and uneven clamping force. During the processing, the parts are prone to slight displacement or vibration, making it difficult to guarantee the processing accuracy. After processing, there is no effective ejection and unloading mechanism. Workers need to manually remove the parts from the machine tool, which is cumbersome and time-consuming. Improper operation may also damage the surface of the parts, seriously affecting production efficiency.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, innovative designs were implemented based on existing machine tools for parts processing. Utility Model Content

[0006] The purpose of this utility model is to provide a high-precision machining tool for valve parts, so as to solve the problems mentioned in the background art of insufficient clamping stability and inability to eject and pick up materials after machining when performing high-precision machining of valve parts.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-precision machining tool for valve parts includes a machine base, a column located in the middle of the rear side of the machine base, a crossbeam connected to the front side of the column, and a machining device connected to the front side of the crossbeam that moves left and right. The surface of the machine base has a sliding groove and a slot. A valve workpiece is placed in the middle of the upper surface of the machine base. First clamping blocks are located on the left and right sides of the upper surface of the machine base, forming a clamping structure on the left and right outer sides of the valve workpiece. A second clamping block is located in the slot in the middle of the machine base, forming a clamping structure on the inner side of the valve workpiece. A top column extends through the inner side of the machine base.

[0009] Preferably, a rotating handle is provided on the lower right side of the machine tool base, and a transmission rod is connected to the left end of the rotating handle, and the left end of the transmission rod is rotatably connected to the left side of the inside of the machine tool base.

[0010] Using the above technical solution, the rotating handle on the lower right side of the machine tool base and the transmission rod connected to the left end can be rotated by rotating the rotating handle to drive the transmission rod to rotate, providing power for subsequent adjustment of the clamping structure. The operation is simple and the efficiency of adjusting the clamping device is improved.

[0011] Preferably, the transmission rod is provided with a first threaded rod on both the left and right sides, and the threads of the first threaded rods on the left and right sides of the transmission rod are opposite. The outer side of each first threaded rod is threadedly connected to a movable plate, and the bottom of the movable plate is slidably connected to the slide groove on the bottom surface of the machine tool base through a slider. The first clamping block is fixedly installed above the movable plate.

[0012] The above technical solution is adopted. The first threaded rod, the moving plate and the first clamping block on the transmission rod have opposite thread directions. When the transmission rod is rotated, the moving plate can move relative to or away from each other, thereby driving the first clamping block to adjust the spacing. This can adapt to the clamping requirements of valve workpieces of different sizes and improve the versatility of the clamping device.

[0013] Preferably, a worm gear is provided in the middle of the transmission rod, and a worm wheel is meshed with the rear side of the worm gear, and the bottom end of the worm wheel is rotatably connected to the bottom surface inside the machine tool base.

[0014] By adopting the above technical solution, the worm gear in the middle of the transmission rod and the worm wheel meshing on the rear side have a self-locking transmission structure. After the position of the second clamping block is adjusted, it can prevent it from changing on its own due to external forces and other factors, thus ensuring the stability of clamping the inner side of the valve workpiece.

[0015] Preferably, a second threaded rod is connected and installed above the worm gear, and a threaded sleeve is threadedly connected above the second threaded rod, and a lifting block is connected to the top of the threaded sleeve.

[0016] By adopting the above technical solution, the second threaded rod, threaded sleeve and lifting block connected by the worm gear can drive the second threaded rod to rotate through the worm gear, which can accurately control the lifting height of the lifting block, thereby accurately adjusting the position of the second clamping block, ensuring uniform clamping force on the inner side of the valve workpiece and improving clamping stability.

[0017] Preferably, a top column is fixedly installed on the top surface of the middle of the lifting block, and the lower part of the second clamping block is hinged to the left and right sides of the lifting block.

[0018] Using the above technical solution, after the top column on the lifting block and the hinged second clamping block are processed, the top column can lift the valve workpiece to facilitate material removal; at the same time, the hinged structure between the second clamping block and the lifting block allows the second clamping block to rotate flexibly when the top column rises.

[0019] Preferably, the second clamping block has a curved groove in the middle, and fixing blocks are fixedly installed on the left and right sides inside the machine tool base. A limit post is provided on the front side of the fixing block, and the limit post passes through the inside of the curved groove.

[0020] By adopting the above technical solution, the curved groove of the second clamping block, the fixed block of the machine tool base and the limiting post, the limiting post slides in the curved groove, which restricts the movement trajectory of the second clamping block, making it more stable in the process of clamping and releasing the valve workpiece, and further improving the clamping stability.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the valve parts are processed by high-precision machine tools.

[0022] 1. Stable clamping ensures accuracy: Through the coordinated action of components such as the first threaded rod, the moving plate, the first clamping block, the worm gear, the worm wheel, and the second threaded rod, stable clamping of the inner and outer sides of the valve workpiece is achieved, ensuring uniform clamping force. At the same time, in conjunction with the curved groove of the second clamping block, the fixed block of the machine tool base, and the limiting post, the limiting post slides in the curved groove to ensure uniform clamping force on the inner side of the valve workpiece, improve clamping stability, effectively avoid displacement and vibration of the parts during processing, and ensure processing accuracy.

[0023] 2. Convenient ejection improves efficiency: Utilizing the structural design of the top column and the second clamping block, the top column on the lifting block and the hinged second clamping block can lift the valve workpiece after processing, making it easy to pick up the material. After processing, the valve workpiece can be automatically ejected, simplifying the material picking operation, avoiding damage to the surface of the parts caused by manual material picking, and improving production efficiency.

[0030] 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.

[0031] Please see Figure 1-5 This utility model provides a technical solution:

[0032] A high-precision machining tool for valve parts includes a machine base 1, a column 2 disposed in the middle of the rear side of the machine base 1, a crossbeam 3 connected to the front side of the column 2, and a machining device 4 movably connected to the front side of the crossbeam 3. The surface of the machine base 1 is provided with a sliding groove and a slot. A valve workpiece 5 is placed in the middle of the upper part of the machine base 1. First clamping blocks 10 are disposed on the left and right sides of the upper surface of the machine base 1, and the first clamping blocks 10 form a clamping structure on the left and right sides of the outer side of the valve workpiece 5. A second clamping block 17 is disposed in the slot in the middle of the machine base 1, and the second clamping block 17 forms a clamping structure on the inner side of the valve workpiece 5. A top column 16 is provided through the inner side of the machine base 1.

[0033] A rotating handle 6 is provided on the lower right side of the machine tool base 1, and a transmission rod 7 is connected to the left end of the rotating handle 6. The left end of the transmission rod 7 is rotatably connected to the left side of the machine tool base 1. The rotating handle 6 on the lower right side of the machine tool base 1 and the transmission rod 7 connected to the left end can drive the transmission rod 7 to rotate by rotating the rotating handle 6, which provides power for subsequent adjustment of the clamping structure. The operation is simple and improves the efficiency of adjusting the clamping device.

[0034] The transmission rod 7 has a first threaded rod 8 on both the left and right sides, and the threads of the first threaded rod 8 on the left and right sides of the transmission rod 7 are opposite. The outer side of the first threaded rod 8 is threadedly connected to a moving plate 9, and the bottom of the moving plate 9 is slidably connected to the inner bottom groove of the machine tool base 1 through a slider. The first clamping block 10 is fixedly installed above the moving plate 9. The first threaded rod 8, the moving plate 9 and the first clamping block 10 on the transmission rod 7 have opposite threads. When the transmission rod 7 is rotated, the moving plate 9 can move relative to or away from each other, thereby driving the first clamping block 10 to adjust the spacing. This can adapt to the clamping requirements of valve workpieces 5 of different sizes and improve the versatility of the clamping device.

[0035] A worm gear 11 is installed in the middle of the transmission rod 7, and a worm wheel 12 is meshed with the rear side of the worm gear 11. The bottom end of the worm wheel 12 is rotatably connected to the inner bottom surface of the machine tool base 1. A second threaded rod 13 is connected and installed above the worm wheel 12, and a threaded sleeve 14 is threadedly connected to the top of the second threaded rod 13. A lifting block 15 is connected to the top of the threaded sleeve 14. The transmission structure of the worm gear 11 in the middle of the transmission rod 7 and the worm wheel 12 meshing with the rear side has self-locking property. After the position of the second clamping block 17 is adjusted, it can prevent it from changing on its own due to external forces and other factors, thus ensuring the stability of clamping the inner side of the valve workpiece 5. The second threaded rod 13, the threaded sleeve 14 and the lifting block 15 connected by the worm wheel 12 drive the second threaded rod 13 to rotate, which can accurately control the lifting height of the lifting block 15, thereby accurately adjusting the position of the second clamping block 17, ensuring uniform clamping force on the inner side of the valve workpiece 5 and improving clamping stability.

[0036] A top column 16 is fixedly installed on the top surface of the lifting block 15, and the second clamping block 17 is hinged to the left and right sides of the lifting block 15. A curved groove 18 is opened in the middle of the second clamping block 17, and a fixing block 20 is fixedly installed on the left and right sides inside the machine tool base 1. A limit post 19 is provided on the front side of the fixing block 20, and the limit post 19 passes through the inside of the curved groove 18. After the top column 16 on the lifting block 15 and the hinged second clamping block 17 are processed, the top column 16 rises to lift the valve workpiece 5, which is convenient for material removal. At the same time, the hinge structure between the second clamping block 17 and the lifting block 15 allows the second clamping block 17 to rotate flexibly when the top column 16 rises. The curved groove 18 of the second clamping block 17, the fixing block 20 of the machine tool base 1, and the limit post 19 slide in the curved groove 18, which restricts the movement trajectory of the second clamping block 17, making it more stable in the process of clamping and releasing the valve workpiece 5, and further improving the clamping stability.

[0037] Working principle:

[0038] In use, the valve workpiece 5 is first placed on the machine tool base 1. The handle 6 on the lower right side of the machine tool base 1 is rotated, which drives the transmission rod 7 to rotate. The first threaded rods 8 with opposite thread directions on the left and right sides of the transmission rod 7 rotate accordingly, causing the moving plate 9 threaded to the first threaded rod 8 to move relative to or away from each other. This, in turn, drives the first clamping block 10 above the moving plate 9 to adjust the spacing and clamp the outer side of the valve workpiece 5. The worm gear 11 in the middle of the transmission rod 7 rotates, and the worm wheel 12 meshing with the rear side of the worm gear 11 rotates accordingly. The worm wheel 12 drives the second threaded rod 13 connected above to rotate. The second threaded rod 13 passes through the threaded sleeve 1. 4. The lifting block 15 is raised or lowered to adjust the height of the second clamping block 17 and clamp the inner side of the valve workpiece 5. During this process, the curved groove 18 in the middle of the second clamping block 17 cooperates with the front limiting post 19 of the fixed block 20 to ensure the smooth movement of the second clamping block 17. After clamping is completed, the cross frame 3 and the processing device 4 perform high-precision processing on the valve workpiece 5. After processing is completed, the handle 6 is rotated in the opposite direction to make the worm gear 12 drive the second threaded rod 13 to rotate, the lifting block 15 rises, the top post 16 lifts the valve workpiece 5, and at the same time the second clamping block 17 rotates around the hinge point with the lifting block 15 to release the valve workpiece 5, making it convenient for the worker to pick up the material.
