Description

Technical Field

[0001] This invention relates to the field of valve processing technology, and in particular to a composite machining tool. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, and overflow pressure relief. In the valve manufacturing industry, valve processing typically involves multiple steps including turning, drilling, and milling. Traditional valve processing machine tools mostly employ a single-station design, meaning only one valve can be processed at a time. However, this design has the following problems:

[0003] Firstly, on single-station machine tools, operators need to frequently perform operations such as loading, fixing, and unloading, resulting in long idle times and low processing efficiency. For mass production, the pace of manual operation is difficult to match with the processing speed of the machine tool, making it impossible to alternate between operations while clamping and fixing the valve, thus affecting the processing efficiency of the valve. Moreover, after turning the two ends of the valve, the inner cavity of the valve will be left with turning debris, which is inconvenient to blow away while unloading, thus increasing the trouble of secondary cleaning for the staff. In order to solve the above problems, this invention proposes a composite machining tool. Summary of the Invention

[0004] In view of the fact that in the above-mentioned or existing technologies, on single-station machine tools, operators need to frequently perform operations such as loading, fixing, and unloading, resulting in long idle time of the machine tool and low processing efficiency, for mass production, the rhythm of manual operation is difficult to match with the processing speed of the machine tool, and it is impossible to clamp and fix the valve while alternating, thus affecting the processing efficiency of the valve.

[0010] In a preferred embodiment of the composite machining tool of the present invention, the adjusting component includes a fixed frame disposed at the lower end of the support block, the fixed frame being movably connected to the upper end of the push plate, a lead screw sleeve being fixedly installed at the lower middle part of the fixed frame, a lead screw being rotatably installed at the upper end of the push plate via a bearing, wedge blocks being welded on both sides of the fixed frame, receiving grooves being provided on both sides of the support block, an arc block being provided in the inner cavity of the receiving groove, a smooth straight rod being welded on the side of the arc block near the wedge block, and the end of the smooth straight rod away from the arc block passing through the receiving groove and fitting against the wedge block.

[0015] Furthermore, during the rotation of the switching frame, the support block on the push plate, in conjunction with the positioning frame, presses and positions the valve to be processed, thereby ensuring the cutting effect of the valve. At the same time, due to the rotation of the switching frame, the corresponding push plate of another processed valve will move from the plane of the trapezoidal plate to the inclined surface of the trapezoidal plate. As the pressure of the push plate is removed, the processed valve on the support block is unlocked, making it convenient for the operator to remove the processed valve. This achieves the effect of pressing and limiting the valve during the alternating switching of valves, thereby improving the processing efficiency of the valve.

[0016] It can also make the wedge block on the fixed frame push the smooth straight rods on both sides of the support block simultaneously. The smooth straight rods further drive the arc block to move out of the receiving groove. By controlling the displacement of the arc block, the storage space of the arc groove of the support block can be controlled, thus making it suitable for valves of different sizes. This further improves the limiting effect on valves of different sizes and further improves the diversity of valve machine tool processing.

[0017] The valve to be processed can be rotated to align with the turret on the machine tool body, and the processed valve can be rotated to align with the corresponding jet pipe at the same time. The high-pressure airflow can blow out the remaining processing debris in the valve chamber, thus saving the workers the trouble of secondary cleaning and making it easier for the workers to remove the processed valve.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, referring to Figures 1 to 5 This is the first embodiment of the present invention. This embodiment provides a composite machining tool that can realize alternating switching processing of valves, while clamping and fixing the valves during the alternating switching process, thereby improving the processing efficiency of the valves. It includes an alternating positioning mechanism 100, which includes a machine tool body 101 and a collection groove 106 disposed in the middle of the machine tool body 101. A switching frame 108 is disposed in the inner cavity of the collection groove 106. A support block 109 is disposed inside the switching frame 108. A deflection component for driving the switching frame 108 to rotate and switch is disposed below the inner cavity of the collection groove 106, and a clamping component disposed inside the switching frame 108 for pressing the support block 109. An adjustment component for adapting to valves of different sizes is disposed inside the support block 109. A cleaning mechanism is disposed on one side of the switching frame 108. The cleaning mechanism includes a chip blowing component disposed on one side of the switching frame 108 for blowing away debris remaining in the inner cavity of the valve.

[0034] In this embodiment, the valve to be processed is placed in the support block 109 on the switching frame 108, with both ends of the valve to be turned parallel to the cutting seat 102, and the middle part of the valve placed in the arc-shaped groove of the support block 109. Then, the deflection assembly is controlled to rotate, causing the switching frame 108 to rotate as well, until the valve to be processed is aligned with the turret 103 on the machine tool body. At this time, another valve that has been processed will also rotate out from the aligned position of the turret 103 on the machine tool body, following the rotation of the switching frame 108. Simultaneously, during the rotation of the switching frame 108, the clamping assembly designed inside the switching frame 108, as the valve to be processed is in place, presses... The clamping assembly clamps and positions the valve to be processed, thus ensuring the cutting effect of the valve. At the same time, the clamping assembly is unlocked by the rotation of the switching frame 108 when another valve is processed, making it easy for the operator to remove the processed valve. This allows for alternating processing of valves, thereby improving the processing efficiency of the machine tool. During the alternation of valves, the valve is clamped and fixed, which improves the processing efficiency. When the switching frame 108 deflects into place, the processed valve also deflects to the chip blowing assembly, which then blows the chips out of the valve's inner cavity with compressed air, thus eliminating the need for secondary cleaning.

[0035] Specifically, the deflection assembly includes a servo motor 112 positioned below the collection tank 106. A transmission rod 113 is mounted on the output end of the servo motor 112. A traction frame 105 is located on the right side of the machine tool body 101. The middle portion of the transmission rod 113 passes through the lower end of the switching frame 108, and the transmission rod 113 is detachably connected to the switching frame 108. Slide rods 114 are welded to both the left and right sides of the switching frame 108. An annular groove 115 is formed on the inner wall of the collection tank 106 near the slide rod 114. The annular groove 115 is designed with... There are two slide rods 114, the size of which is matched with the size of the annular slide groove 115, and the slide rods 114 and the annular slide groove 115 are slidably connected. The side of the switching frame 108 is V-shaped. Cutting seats 102 are provided on both sides of the upper part of the machine tool body 101. A turret 103 is provided on the inner side of the cutting seat 102. A control panel 104 is provided at the front end of the side of the machine tool body 101 near the traction frame 105. A chip removal door 107 is provided in the middle of the front end of the machine tool body 101. The chip removal door 107 is located in front of the collection tank 106.

[0036] In this embodiment, the servo motor 112 is fixedly connected to the collection groove 106 by bolts. During deflection, the valve to be processed is first placed in the support block 109 on the switching frame 108, and the two ends of the valve to be turned are parallel to the cutting seat 102. At the same time, the middle part of the valve is placed in the arc-shaped groove of the support block 109. Then, the servo motor 112 is turned on, and the servo motor 112 drives the transmission rod 113 to rotate forward. The transmission rod 113 drives the switching frame 108 to rotate accordingly until the valve to be processed is aligned with the tool turret 103 on the machine tool body. At this time, another valve that has been processed will also follow the switching frame 108. The turret 103 on the machine tool body rotates out of its aligned position, thereby realizing the alternating switching of valve processing, which improves the processing efficiency of the machine tool body for valves. Compared with traditional valve processing, it greatly shortens the machine tool downtime. At the same time, through the cooperation of the slide bar 114 and the annular slide groove 115, the rotation of the switching frame 108 can be guaranteed to be smooth, and the burden on the transmission rod 113 caused by the weight of the switching frame 108 and the valve can be reduced, thereby improving the service life of the transmission rod 113. In addition, with the chip removal door 107 design on the machine tool body 101, the cutting chips collected in the collection groove 106 can be centrally cleaned and discharged.

[0037] Furthermore, the clamping assembly includes a positioning frame 111 disposed above the support block 109. The lower end of the positioning frame 111 is fixedly connected to the upper end of the switching frame 108. A first sliding groove 110 is provided on the inner side of the upper end of the switching frame 108, and two first sliding grooves 110 are provided. A first slider 120 is fixedly installed on the side of the support block 109 near the first sliding groove 110. The first slider 120 is slidably connected to the first sliding groove 110. A trapezoidal plate 116 is fixedly installed in the middle of the inner cavity of the collecting groove 106, and the trapezoidal plate... 116 is located in the middle of the switching frame 108. The front and rear sides of the upper end of the trapezoidal plate 116 are provided with a first smooth surface 117. The lower end of the support block 109 is welded with a push plate 118. The lower end of the push plate 118 is set as an arc surface. The lower end of the push plate 118 is in contact with the surface of the trapezoidal plate 116. The side of the support block 109 away from the turret 103 is welded with a limit plate 119. The support blocks 109 are symmetrically arranged on the front and rear sides of the switching frame 108. An arc-shaped placement groove is opened in the middle of the inner side of the support block 109.

[0038] In this embodiment, during the rotation of the switching frame 108, the switching frame 108 will drive the support block 109 to rotate accordingly. At the same time, the push plate 118 below the support block 109 will move along the inclined surface of the trapezoidal plate 116. The reaction force of the inclined surface of the trapezoidal plate 116 pushes the push plate 118, causing the push plate 118 to move upward, while simultaneously driving the support block 109 to slide upward. When the positioning frame 111 rotates to a position flush with the turret 103, the push plate 118 moves from the inclined surface of the trapezoidal plate 116 to the trapezoidal plate 109. On the plane of plate 116, the push plate 118 stops moving, and the support block 109 on the push plate 118, together with the positioning frame 111, clamps and positions the valve to be processed, thereby ensuring the cutting effect of the valve. At the same time, due to the rotation of the switching frame 108, the corresponding push plate 118 of another valve that has been processed will move from the plane of trapezoidal plate 116 to the inclined surface of trapezoidal plate 116. Due to the loss of the pressure from the push plate 118, the valve that has been processed on the support block 109 will be clamped and positioned. The valve is unlocked, making it easier for workers to remove the finished valve. This achieves the goal of clamping and limiting the valve during valve switching, thereby improving the processing efficiency. Simultaneously, the first smooth surface 117 on the trapezoidal plate 116 ensures that the push plate 118 can smoothly transition from the inclined surface to the flat surface of the trapezoidal plate 116, further enhancing valve control. During the rotation of the two push plates 118 on the switching frame 108, the push plates 118 also push away valve processing debris remaining on the trapezoidal plate 116. Combined with the vertically designed switching frame 108, this ensures that residual debris is rotated and discharged during the switching frame 108's movement, reducing the hassle of cleaning debris for workers. The limiting plate 119 on the support block 109 ensures that the valve placed in the arc-shaped groove of the support block 109 is limited during the rotation of the switching frame 108, preventing the valve from falling off during rotation.

[0039] The adjustment assembly includes a fixed frame 121 located at the lower end of the support block 109. The fixed frame 121 is movably connected to the upper end of the push plate 118. A lead screw sleeve 123 is fixedly installed in the middle of the lower end of the fixed frame 121. A lead screw 122 is rotatably installed on the upper end of the push plate 118 via a bearing. Wedge blocks 124 are welded to both sides of the fixed frame 121. Receiving grooves 125 are provided on both sides of the support block 109. An arc-shaped block 126 is provided in the inner cavity of the receiving groove 125. The side of the arc-shaped block 126 near the wedge block 124... A smooth straight rod 127 is welded on. The end of the smooth straight rod 127 away from the arc-shaped block 126 passes through the receiving groove 125 and fits against the wedge block 124. The size of the lead screw 122 is adapted to the size of the lead screw sleeve 123, and the lead screw 122 and the lead screw sleeve 123 are threadedly connected. The arc-shaped block 126 is movably connected to the receiving groove 125, and the arc-shaped blocks 126 are symmetrically arranged. A first spring 128 is fixedly installed on the side of the arc-shaped block 126 near the wedge block 124, and the other end of the first spring 128 is fixedly connected to the inner wall of the receiving groove 125.

[0040] In this embodiment, during adjustment, rotating the lead screw 122 causes the lead screw 122, in conjunction with the lead screw sleeve 123, to move the fixed frame 121 upward. This causes the wedge-shaped block 124 on the fixed frame 121 to simultaneously push the smooth straight rods 127 on both sides of the support block 109. The smooth straight rods 127 further drive the arc-shaped block 126 out of the receiving groove 125, while simultaneously stretching the first spring 128. By controlling the displacement of the arc-shaped block 126, the storage space of the arc-shaped groove of the support block 109 is controlled, thus making it suitable for valves of different sizes. This further improves the limiting effect on valves of different sizes and enhances the versatility of valve machining. The receiving groove 125 allows the arc-shaped block 126 to be stored, facilitating its adjustment. The first spring 128 allows the arc-shaped block 126 to be reset and returned to the receiving groove 125.

[0041] In operation, during deflection, the valve to be machined is first placed in the support block 109 on the switching frame 108. Simultaneously, the two ends of the valve to be machined are aligned parallel to the cutting seat 102, with the middle of the valve placed in the arc-shaped groove of the support block 109. Then, the servo motor 112 is activated, driving the transmission rod 113 to rotate clockwise. The transmission rod 113 then drives the switching frame 108 to rotate accordingly until the valve to be machined is aligned with the turret 103 on the machine tool body. At this point, another valve that has been machined will also rotate out from its aligned position on the turret 103, following the rotation of the switching frame 108. This achieves alternating switching of valves. This process improves the machining efficiency of the machine tool body for valve processing, significantly reducing machine downtime compared to traditional valve machining. Simultaneously, during the rotation of the switching frame 108, the support block 109 rotates accordingly. At the same time, the push plate 118 below the support block 109 moves along the inclined surface of the trapezoidal plate 116. The reaction force of the inclined surface of the trapezoidal plate 116 pushes the push plate 118 upwards, simultaneously causing the support block 109 to slide upwards. When the positioning frame 111 rotates to a position flush with the turret 103, the push plate 118 moves from the inclined surface of the trapezoidal plate 116 to the plane of the trapezoidal plate 116. At this point, the push plate 118 stops moving, and the support block 109 on the push plate 118, in conjunction with the positioning frame 111, clamps and positions the valve to be processed, thus ensuring the cutting effect of the valve. Simultaneously, due to the rotation of the switching frame 108, the corresponding push plate 118 of the other completed valve moves from the plane of the trapezoidal plate 116 to the inclined surface of the trapezoidal plate 116. Because the pressure from the push plate 118 is removed, the valve on the support block 109 is unlocked, allowing the operator to easily remove the completed valve. This achieves valve clamping and limiting during valve switching, thereby improving efficiency. Regarding the valve processing efficiency, during adjustment, rotating the lead screw 122, in conjunction with the lead screw sleeve 123, causes the fixed frame 121 to move upward. This causes the wedge block 124 on the fixed frame 121 to simultaneously push the smooth straight rods 127 on both sides of the support block 109. The smooth straight rods 127 further drive the arc block 126 out of the receiving groove 125, while simultaneously stretching the first spring 128. By controlling the displacement of the arc block 126, the storage space of the arc groove in the support block 109 can be controlled, thus making it suitable for valves of different sizes. This further improves the limiting effect on valves of different sizes and enhances the versatility of valve machine tool processing.

[0042] Example 2, refer to Figures 1 to 10This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a composite machining tool, solving the problem of inconvenience in blowing away residual debris from the valve cavity during unloading, thus increasing the hassle of secondary cleaning for workers. The debris blowing assembly includes a pressing rod 201 disposed on a trapezoidal plate 116, located near the servo motor 112. Cylindrical grooves 203 are formed at both ends of the trapezoidal plate 116 near the servo motor 112. A second sliding groove 204 is formed at the upper end of the inner cavity of the cylindrical groove 203. A second slider 210 is fixedly installed at one end of the pressing rod 201 near the second sliding groove 204. A pressure sensor 206 is detachably installed in the inner cavity of the cylindrical groove 203. A small air pump 207 is provided at the rear of the machine tool body 101. The air outlet is connected to a first air jet pipe 208, and the middle of the first air jet pipe 208 is connected to a second air jet pipe 209. The second air jet pipe 209 is located on the front side of the machine tool body 101, and the first air jet pipe 208 is located on the rear side of the machine tool body 101. A second smooth surface 202 is provided on the side of the switching frame 108 near the extrusion rod 201. The size of the second slider 210 is adapted to the size of the second slide groove 204, and the second slider 210 is slidably connected to the second slide groove 204. A second spring 205 is fixedly installed in the inner cavity of the second slide groove 204, and the other end of the second spring 205 is fixedly connected to the second slider 210. The signal output end of the pressure sensor 206 is connected to the signal input end of the control panel 104, and the signal output end of the control panel 104 is connected to the signal input end of the small air pump 207.

[0043] In this embodiment, the extrusion rod 201 is disposed in the cylindrical groove 203. Before the valve to be processed rotates to be aligned with the turret 103 on the machine tool body, the second smooth surface 202 on the switching frame 108 will contact the smooth straight rod 127. As the switching frame 108 continues to rotate, the second smooth surface 202 will push the smooth straight rod 127, causing the smooth straight rod 127 to insert into the receiving groove 125. At the same time, the second spring 205 is stretched, causing the smooth straight rod 127 to extrude pressure on the pressure sensor 206. After the pressure sensor 206 reaches the pressure threshold, the pressure sensor 206 transmits a signal to the control panel 104. The control panel 104 controls the small air pump 207 to turn on, thereby ejecting high-pressure airflow through the first jet pipe 208 and the second jet pipe 209. At this time, the valve to be processed... As the valve rotates to align with the turret 103 on the machine tool body, the finished valve rotates to align with the corresponding air jet pipe. High-pressure airflow blows out the remaining machining debris in the valve chamber, eliminating the need for secondary cleaning and facilitating the removal of the finished valve. The second smooth surface 202 ensures smooth contact between the switching frame 108 and the extrusion rod 201, achieving a smooth pushing effect on the extrusion rod 201. The cylindrical groove 203 accommodates the smooth straight rod 127, facilitating the extrusion triggering of the pressure sensor 206. The first air jet pipe 208 and the second air jet pipe 209 work together to blow away the debris from the rotated valve.

[0044] The rest of the structure is the same as in Example 1.

[0045] During use, before the valve to be processed rotates to align with the turret 103 on the machine tool body, the second smooth surface 202 on the switching frame 108 contacts the smooth rod 127. As the switching frame 108 continues to rotate, the second smooth surface 202 pushes the smooth rod 127, causing it to insert into the receiving groove 125. Simultaneously, the second spring 205 is stretched, causing the smooth rod 127 to press against the pressure sensor 206. After the pressure sensor 206 reaches the pressure threshold, it transmits a signal to the control panel 104. The control panel 104 controls the small air pump 207 to turn on, which then sprays high-pressure airflow through the first jet pipe 208 and the second jet pipe 209. At the same time as the valve to be processed rotates to align with the turret 103 on the machine tool body, the processed valve rotates to align with the corresponding jet pipe. The high-pressure airflow blows out the remaining processing debris in the valve chamber, thus eliminating the need for secondary cleaning by the operator and making it easier for the operator to remove the processed valve.
