[0026] Furthermore, the present utility model is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present utility model, for the sake of convenience in explanation, the cross-sectional views showing the device structure are locally enlarged not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.
[0027] Referring to Figures 1-4 , the present utility model provides a numerically controlled lathe with turning and milling compound functions, including:
[0028] A main body unit 100, including a lathe main body 101. A milling cutter holder 102 is provided in the middle of the top of the lathe main body 101. A surface turning tool is provided on the right side of the top of the lathe main body 101. A lathe protection cover 103 is provided outside the surface turning tool. The lathe protection cover 103 is rotatably connected to the lathe main body 101 through a hinge;
[0029] A protection cover locking unit 200, including an active lock block 201 with a hollow structure. The active lock block 201 is fixedly connected to the lathe protection cover 103. Two passive lock blocks 202 are fixedly connected to the front surface of the lathe main body 101. The active lock block 201 is connected to the passive lock blocks 202 when the lathe protection cover 103 is in the closed state.
[0030] Among them, a cavity is provided inside the inner side of the passive lock block 202. A spring 202a is fixedly connected inside the cavity. The other end of the spring 202a is fixedly connected to a lock rod 202b. The lock rod 202b is movably connected to the passive lock block 202 and penetrates to the outside. A card slot 202c is provided on the outer wall of the lock rod 202b. The outer end of the lock rod 202b is hemispherical. The lock rod 202b is ejected outward by the spring 202a to prevent the lock rod 202b from resetting autonomously, thereby improving the fixing effect.
[0031] Furthermore, connection holes are provided on both sides of the active lock block 201. The connection holes are connected to the lock rod 202b. A fixed semi-ring 201c is arranged inside the connection holes. The fixed semi-ring 201c is fixedly connected to the inner wall of the active lock block 201. The fixed semi-ring 201c has the same diameter and center position as the connection holes. By inserting the lock rod 202b into the connection holes, the passive lock block 202 is connected to the active lock block 201.
[0032] Furthermore, a push rod 201a is movably connected to the outer wall of the active lock block 201. The inner side of the push rod 201a is movably connected inside the active lock block 201 and fixedly connected to a connection slider 201d. An active semi-ring 201b is fixedly connected above the connection slider 201d. The active semi-ring 201b has the same size as the fixed semi-ring 201c but in the opposite direction. By driving the connection slider 201d to move through the push rod 201a, the active semi-ring 201b is driven to move.
[0033] Furthermore, positioning rings are fixedly connected to the inner walls of the fixed semi-ring 201c and the active semi-ring 201b. The positioning rings are fitted with the card slots 202c, thereby fixing the lock rod 202b.
[0034] Furthermore, a through hole is provided in the middle of the connection slider 201d. A limiting slide rod 201e is movably connected inside the through hole. The limiting slide rod 201e is fixedly connected to the inside of the active lock block 201, so that the active semi-ring 201b moves in a straight line.
[0035] During use, when the lathe protection cover 103 is closed, the lock rod 202b is pushed back into the passive lock block 202 by the extrusion of the active lock block 201 and the spring 202a is compressed. Subsequently, the spring 202a drives the lock rod 202b to rebound and insert into the connection holes. By driving the connection slider 201d to move through the push rod 201a, the connection slider 201d drives the active semi-ring 201b to move and cooperate with the fixed semi-ring 201c to clamp the card slot 202c, thereby completing the locking work of the lathe protection cover 103. After resetting the push rod 201a, the lathe protection cover 103 is opened upward. By the extrusion between the spherical outer end of the lock rod 202b and the active lock block 201, the lock rod 202b is pushed back into the passive lock block 202, thereby opening the lathe protection cover 103. By pushing the push rod 201a, the opening and closing of the lathe protection cover 103 can be completed. Therefore, it is convenient to quickly operate the opening and closing states of the lathe protection cover 103, thereby improving the processing efficiency.
[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
