Technical Field

[0001] The utility model relates to the technical field of numerical control lathes, in particular to a vertical turning and grinding compound numerical control lathe for valve processing. Background Technique

[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters (temperature, pressure, and flow rate) of the transported medium. According to its functions, it can be divided into shut-off valves, check valves, regulating valves, etc. A valve is a control component in a fluid transportation system and has functions such as cutoff, regulation, diversion, preventing backflow, pressure stabilization, shunt, or overflow pressure relief. Valves used in fluid control systems range from the simplest stop valves to various valves used in extremely complex automatic control systems, and their varieties and specifications are quite numerous.

[0003] A numerical control lathe is usually used to process shaft and disc-shaped rotating parts, and has advantages such as a wide processing range, convenient programming, and quick and convenient tool change.

In the middle of one side of the connecting seat 15, there is a turning main body 16. In the middle of the side of the connecting seat 15 away from the turning main body 16, there is a grinding main body 17. At the bottom ends on both sides of the connecting seat 15, there are positioning grooves 18. On both sides of the top of the mounting plate 11, there are cavities 19. On the inner walls of the two cavities 19, there are lead screws 20 arranged through bearings. Outside the two lead screws 20, there are L-shaped inserts 21. On one side of the two L-shaped inserts 21, there are springs 22.

[0023] In this embodiment, as Figure 1 shown, the housing assembly 1 includes a base 101. At the top of the base 101, there is a CNC lathe main body 102. On one side of the CNC lathe main body 102, there is a fixture 103.

[0024] In this embodiment, as Figure 4 shown, the central axis of the servo motor 7 is consistent with the central axis of the connecting shaft 10; it realizes the transformation of the positions of the turning main body 16 and the grinding main body 17 according to the needs of the user, greatly improving the convenience of the CNC lathe main body 102 during valve processing, thus meeting the requirements of the vertical turning and grinding compound CNC lathe for valve processing.

[0025] In this embodiment, as Figure 4 shown, a clamping structure is set between the card slot 8 and the control rod 13; it realizes the fixation of the mounting plate 11, avoiding the situation that the workpiece processing is unqualified due to the rotation of the mounting plate 11 during use, thus improving the stability of the mounting plate 11 during fixation.

[0026] In this embodiment, as Figure 2 shown, a sliding connection is set between the guide rod 6 and the fixed seat 5; it improves the uncertainty of the fixed seat 5 during movement, thus avoiding the situation that the fixed seat 5 deviates during movement.

[0027] In this embodiment, as Figure 3As shown, the internal dimensions of the cavity 19 are consistent with the external dimensions of the L-shaped insert block 21; the moving direction of the L-shaped insert block 21 is made single to avoid the situation of offset during the movement of the L-shaped insert block 21, thereby greatly increasing the stability of the L-shaped insert block 21 during the movement.

[0028] In this embodiment, as Figure 2 shown, the lead screw 20, the L-shaped insert block 21, and the spring 22 are all symmetric with respect to the vertical center line of the mounting plate 11; the rapid installation of the connecting seat 15 is realized, and the problem that the connecting seat 15 needs to use a variety of auxiliary tools during installation, resulting in cumbersome operation, is solved, thereby greatly improving the working efficiency of the connecting seat 15 during installation.

[0029] The usage method and advantages of the present utility model: When the vertical turning and grinding compound CNC lathe for valve processing is in use, the working process is as follows:

[0030] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, first, place the CNC machine tool main body 102 on the designated position through the base 101, then fix the valve to be processed inside the fixture 103, then place the connecting seat 15 in the mounting groove 14 at the top of the mounting plate 11, and then drive the two lead screws 20 to rotate by rotating the two knobs. The lead screw 20 drives the L-shaped insert block 21 to move under the limit of the cavity 19. At this time, while the L-shaped insert block 21 moves, the spring 22 is compressed until a clamping structure is formed between the L-shaped insert block 21 and the positioning groove 18. By using the cooperation of the L-shaped insert block 21 and the positioning groove 18, the fixing of the connecting seat 15 is realized, thereby realizing the rapid installation of the connecting seat 15, solving the problem that the connecting seat 15 needs to use a variety of auxiliary tools during installation, resulting in cumbersome operation, and further greatly improving the working efficiency of the connecting seat 15 during installation. When the valve needs to be polished, start the servo motor 7 to drive the connecting shaft 10 to rotate. The connecting shaft 10 drives the mounting plate 11 to rotate. The mounting plate 11 drives the grinding main body 17 to rotate through the connecting seat 15, realizing the transformation of the positions of the turning main body 16 and the grinding main body 17 according to the needs of the user, greatly improving the convenience of the CNC machine tool main body 102 during valve processing, thereby meeting the requirements of the vertical turning and grinding compound CNC lathe for valve processing. When the position conversion of the grinding main body 17 is completed, rotate the control rod 13 so that the control rod 13 is clamped inside the clamping groove 8 and forms a clamping structure to realize the fixing of the mounting plate 11, avoiding the situation that the workpiece is unqualified due to the self-rotation of the mounting plate 11 during use, thereby improving the stability of the mounting plate 11 during fixing. By using the cooperation of the threaded rod 4, the guide rod 6, and the rotating motor, the front and rear positions of the connecting seat 15 are adjusted, so that the vertical turning and grinding compound CNC machine tool for valve processing is more convenient to operate during operation.
