Description

Technical Field

[0001] The invention relates to the technical field of valve processing, in particular to a compound processing machine tool. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. In the valve manufacturing industry, valve processing usually involves multiple processes such as turning, drilling, and milling. Most traditional valve processing machines adopt a single-station design, that is, only one valve can be processed at a time, but this design has the following problems: Firstly, on a single-station machine tool, the operator needs to frequently perform operations such as loading, fixing, and unloading, which results in a long idle time of the machine tool and low processing efficiency. For mass production, the rhythm of manual operation is difficult to match the processing speed of the machine tool, and it is impossible to clamp and fix the valve while switching alternately, thereby affecting the processing efficiency of the valve. Moreover, after turning the two ports of the valve, debris splashed by turning will remain in the inner cavity of the valve, which makes it inconvenient to blow away the debris remaining in the inner cavity of the valve while unloading, thereby increasing the trouble of secondary cleaning for the staff. In order to solve the above problems, the present invention proposes a composite processing machine tool. Summary of the invention

[0003] In view of the fact that on the single-station machine tools mentioned above or in the prior art, operators need to frequently perform operations such as loading, fixing, and unloading, which leads to a long idle time of the machine tools and low processing efficiency.

Specific embodiments

[0029] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner 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 separate or alternative embodiment that excludes other embodiments.

[0032] Example 1, refer to Figures 1 to 5, is the first embodiment of the present invention, which provides a composite processing machine tool, which can realize the alternating switching processing of valves, and at the same time clamp and fix the valves during the alternating switching process of the valves, thereby improving the processing efficiency of the valves, including an alternating positioning mechanism 100, which includes a machine tool body 101, and a collecting tank 106 arranged in the middle of the machine tool body 101, the inner cavity of the collecting tank 106 is provided with a switching frame 108, and the interior of the switching frame 108 is provided with a support block 109, and a deflection component for driving the switching frame 108 to rotate and switch is provided below the inner cavity of the collecting tank 106, and a clamping component for clamping the support block 109 is provided inside the switching frame 108, and an adjusting component for adapting to valves of different sizes is provided inside the support block 109, and a cleaning mechanism is provided on one side of the switching frame 108, and the cleaning mechanism includes a chip blowing component arranged on one side of the switching frame 108 for blowing away the debris remaining in the inner cavity of the valve.

[0033] In this embodiment, the valve to be processed is placed in the support block 109 on the switching frame 108, and the two ports 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 groove of the support block 109, and then the deflection assembly is controlled to rotate, and the deflection assembly drives the switching frame 108 to rotate 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 follow the rotation of the switching frame 108 and rotate out from the alignment position of the turret 103 on the machine tool body. At the same time, during the rotation process of the switching frame 108, the clamping assembly designed in the switching frame 108 is cooperated to press the valve to be processed when it is in place. The tightening assembly presses and positions the valve to be processed, thereby ensuring the cutting processing effect of the valve. At the same time, the other processed valve will also unlock the tightening assembly due to the rotation of the switching frame 108, thereby facilitating the staff to remove the processed valve, thereby realizing the alternating switching processing of the valve, thereby improving the processing efficiency of the machine tool body for the valve, and at the same time, the valve is clamped and fixed during the alternating switching process of the valve, thereby improving the processing efficiency and effect of the valve. At the same time, when the switching frame 108 is deflected into place, the processed valve will also deflect to the chip blowing assembly, and then the compressed air chip blowing will be carried out on the inner cavity of the valve, thereby eliminating the trouble of secondary cleaning.

[0034] Specifically, the deflection assembly includes a servo motor 112 disposed below the collection trough 106. A transmission rod 113 is installed at the output end of the servo motor 112. A traction frame 105 is provided on the right side of the machine tool body 101. The middle part of the transmission rod 113 penetrates 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. Annular chutes 115 are formed on the inner wall of the collection trough 106 near the slide rods 114, and two annular chutes 115 are provided. The size of the slide rod 114 is adapted to the size of the annular chute 115, and the slide rod 114 is slidably connected to the annular chute 115. The side surface of the switching frame 108 is V-shaped. Cutting seats 102 are provided on both sides above the machine tool body 101. A turret 103 is provided inside the cutting seat 102. A control panel 104 is provided at the front end 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, and the chip removal door 107 is provided on the front side of the collection trough 106.

[0035] In this embodiment, the servo motor 112 is fixedly connected to the collection trough 106 by means of bolts. During deflection, first, the valve to be processed is placed in the support block 109 on the switching frame 108. At the same time, the two ports of the valve to be turned are parallel to the cutting seat 102, and 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. 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 turret 103 on the machine tool body. At this time, the other processed valve will also rotate out from the alignment position of the turret 103 on the machine tool body following the rotation of the switching frame 108, so as to realize the alternate switching processing of the valve, thereby improving the processing efficiency of the machine tool body for the valve, greatly shortening the downtime of the machine tool compared with the traditional valve machine tool processing. At the same time, through the cooperation of the slide rod 114 and the annular chute 115, the smooth rotation of the switching frame 108 can be ensured, 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. At the same time, in cooperation with the design of the chip removal door 107 on the machine tool body 101, the cutting debris collected in the collection trough 106 can be centrally cleaned and discharged.

[0036] Further, the pressing 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. The inner side of the upper end of the switching frame 108 is provided with a first chute 110, and two first chutes 110 are provided. A first slider 120 is fixedly installed on one side of the support block 109 close to the first chute 110. The first slider 120 is slidably connected to the first chute 110. A trapezoidal plate 116 is fixedly installed in the middle of the inner cavity of the collection tank 106, and the trapezoidal plate 116 is arranged in the middle of the switching frame 108. First smooth surfaces 117 are provided on both the front and rear sides of the upper end of the trapezoidal plate 116. A push plate 118 is welded to the lower end of the support block 109. The lower end of the push plate 118 is an arc surface. The lower end of the push plate 118 is in contact with the surface of the trapezoidal plate 116. A limiting plate 119 is welded to one side of the support block 109 away from the turret 103. The support blocks 109 are symmetrically arranged on the front and rear sides of the switching frame 108. An arc-shaped placement groove is provided in the middle of the inner side of the support block 109.

[0037] In this embodiment, during the rotation of the switching frame 108, the switching frame 108 drives the support block 109 to rotate accordingly. At the same time, the push plate 118 under 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, causing the push plate 118 to move upward and driving the support block 109 to slide upward. When the positioning frame 111 rotates to a position flush with the turret 103, at this time, the push plate 118 moves from the inclined surface of the trapezoidal plate 116 to the flat surface of the trapezoidal plate 116. At this time, the push plate 118 stops moving. At the same time, the support block 109 on the push plate 118 cooperates with the positioning frame 111 to press and position the valve to be processed placed thereon, thereby ensuring the cutting effect of the valve. At the same time, the other processed valve will also rotate with the switching frame 108, causing the corresponding push plate 118 to move from the flat surface of the trapezoidal plate 116 to the inclined surface of the trapezoidal plate 116. Due to the loss of the pressing force of the push plate 118, the processed valve on the support block 109 is unlocked, facilitating the staff to remove the processed valve. Thus, during the valve alternation process, the valve is pressed and limited, improving the processing efficiency of the valve. At the same time, through the cooperation of the first smooth surface 117 on the trapezoidal plate 116, it is ensured that the push plate 118 can smoothly transition from the inclined surface to the flat surface of the trapezoidal plate 116, further improving the limitation of the valve. And during the rotation of the two push plates 118 on the switching frame 108, the push plate 118 also pushes the valve processing debris remaining on the trapezoidal plate 116. Combined with the vertically designed switching frame 108, it is ensured that the residual debris can be rotated and discharged during the movement of the switching frame 108, reducing the trouble of debris cleaning for the staff. Through the setting of the limiting plate 119 on the support block 109, it is ensured that during the rotation of the switching frame 108, a certain limiting effect is exerted on the valve placed in the arc groove of the support block 109, avoiding the situation of the valve falling during the rotation process.

[0038] Among them, the adjusting component includes a fixed frame 121 arranged 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. The upper end of the push plate 118 is rotatably installed with a lead screw 122 through a bearing. Wedge-shaped blocks 124 are welded on both sides of the fixed frame 121. Accommodating grooves 125 are formed on both sides of the support block 109. An arc-shaped block 126 is arranged in the inner cavity of the accommodating groove 125. A smooth straight rod 127 is welded on the side of the arc-shaped block 126 close to the wedge-shaped block 124. One end of the smooth straight rod 127 away from the arc-shaped block 126 penetrates through the accommodating groove 125 and fits with the wedge-shaped 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 is threadedly connected to the lead screw sleeve 123. The arc-shaped block 126 is movably connected to the accommodating 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 close to the wedge-shaped block 124. The other end of the first spring 128 is fixedly connected to the inner wall of the accommodating groove 125.

[0039] In this embodiment, during adjustment, by rotating the lead screw 122, the lead screw 122 cooperates with the lead screw sleeve 123 to drive the fixed frame 121 to move upward, so that the wedge-shaped blocks 124 on the fixed frame 121 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 blocks 126 to move out of the accommodating grooves 125, and at the same time stretch the first spring 128. By controlling the displacement of the arc-shaped blocks 126, the arc-shaped groove storage space of the support block 109 is controlled, so as to be applicable to valves of different sizes, further improving the limiting effect on valves of different sizes and further improving the diversity of valve machine tool processing. Through the setting of the accommodating grooves 125, the arc-shaped blocks 126 can be accommodated, thus facilitating the adjustment of the arc-shaped blocks 126. Through the setting of the first spring 128, the arc-shaped blocks 126 can be driven to reset and retract into the accommodating grooves 125.

[0040] In use, during deflection, first place the valve to be processed in the support block 109 on the switching rack 108. At the same time, align the two ports of the valve to be turned with the cutting seat 102. Place the middle part of the valve in the arc-shaped groove of the support block 109. Then turn on the servo motor 112. The servo motor 112 drives the transmission rod 113 to rotate forward. The transmission rod 113 drives the switching rack 108 to rotate accordingly until the valve to be processed is aligned with the turret 103 on the machine body. At this time, the other processed valve will also rotate with the switching rack 108 and rotate out from the alignment position of the turret 103 on the machine body, thus realizing the alternate switching processing of the valve, improving the processing efficiency of the valve by the machine body, greatly shortening the downtime of the machine compared with the traditional valve machine tool processing. At the same time, during the rotation of the switching rack 108, the switching rack 108 will drive the support block 109 to rotate accordingly. At the same time, the push plate 118 under 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 and driving the support block 109 to slide upward. When the positioning frame 111 rotates to a position flush with the turret 103, at this time, the push plate 118 moves from the inclined surface of the trapezoidal plate 116 to the plane of the trapezoidal plate 116. At this time, the push plate 118 stops moving. At the same time, the support block 109 on the push plate 118 cooperates with the positioning frame 111 to press and position the valve to be processed, thus ensuring the cutting processing effect of the valve. At the same time, the other processed valve will also rotate with the switching rack 108, causing the corresponding push plate 118 to move from the plane of the trapezoidal plate 116 to the inclined surface of the trapezoidal plate 116. Due to the loss of the pressing force of the push plate 118, the processed valve on the support block 109 is unlocked, facilitating the staff to remove the processed valve, thus achieving the pressing and limiting of the valve during the alternate switching of the valve, and improving the processing efficiency of the valve. During adjustment, by rotating the screw rod 122, the screw rod 122 cooperates with the screw rod sleeve 123 to drive the fixed frame 121 to move upward, so that the wedge-shaped block 124 on the fixed frame 121 simultaneously pushes the smooth straight rods 127 on both sides of the support block 109. The smooth straight rods 127 further drive the arc-shaped blocks 126 to move out of the accommodation groove 125, stretching the first spring 128 at the same time. By controlling the displacement of the arc-shaped blocks 126, the storage space of the arc-shaped groove of the support block 109 is controlled, thus being applicable to valves of different sizes, further improving the limiting effect on valves of different sizes, and further improving the diversity of valve machine tool processing.

The size of the second slider 210 is adapted to the size of the second chute 204, and the second slider 210 is slidably connected with the second chute 204. A second spring 205 is fixedly installed in the inner cavity of the second chute 204. The other end of the second spring 205 is fixedly connected with the second slider 210. The signal output end of the pressure sensor 206 is connected with the signal input end of the control panel 104. The signal output end of the control panel 104 is connected with the signal input end of the small air pump 207.

[0042] In this embodiment, the extrusion rod 201 is arranged in the cylindrical groove 203. Before the valve to be processed rotates to align with the turret 103 on the machine tool main body, at this time, the second smooth surface 202 on the switching frame 108 will contact the smooth straight rod 127. During the continuous rotation of the switching frame 108, 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, and at the same time stretching the second spring 205, so that the smooth straight rod 127 squeezes 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, and the control panel 104 controls the small air pump 207 to start, and then high-pressure air flows are ejected through the first air spray pipe 208 and the second air spray pipe 209. At this time, while the valve to be processed rotates to align with the turret 103 on the machine tool main body, the processed valve just rotates to be flush with the corresponding air spray pipe, and the remaining processing debris in the valve chamber is blown out by the high-pressure air flow, thus saving the trouble of secondary cleaning by the staff, and thus facilitating the staff to remove the processed valve. Through the setting of the second smooth surface 202, the smooth contact between the switching frame 108 and the extrusion rod 201 can be ensured, so as to achieve the effect of smoothly pushing the extrusion rod 201. Through the setting of the cylindrical groove 203, the smooth straight rod 127 can be accommodated, and thus it is convenient to squeeze and trigger the pressure sensor 206. Through the cooperation of the first air spray pipe 208 and the second air spray pipe 209, the processed valve that has rotated into place can be subjected to chip blowing treatment.

[0043] The remaining structures are the same as those in Embodiment 1.

[0044] During use, before the valve to be processed rotates to align with the turret 103 on the machine tool main body, at this time, the second smooth surface 202 on the switching frame 108 will contact the smooth straight rod 127. During the continuous rotation of the switching frame 108, 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, and at the same time stretching the second spring 205, so that the smooth straight rod 127 squeezes 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, and the control panel 104 controls the small air pump 207 to start, and then high-pressure air flows are ejected through the first air spray pipe 208 and the second air spray pipe 209. At this time, while the valve to be processed rotates to align with the turret 103 on the machine tool main body, the processed valve just rotates to be flush with the corresponding air spray pipe, and the remaining processing debris in the valve chamber is blown out by the high-pressure air flow, thus saving the trouble of secondary cleaning by the staff, and thus facilitating the staff to remove the processed valve.
