Description

Technical Field

[0001] This utility model relates to the field of machining center turntable technology, specifically, it demonstrates a vertical and horizontal turntable. Background Technology

[0002] The vertical and horizontal CNC rotary table is a common component of CNC milling machines. It is often used as a servo axis of CNC milling machines, namely the C-axis of vertical CNC milling machines and the B-axis of horizontal CNC milling machines. The rotary table is generally equipped with end face fixing screw holes for horizontal machining and T-slots for vertical machining, which facilitates the installation of drilling and milling devices under different machining conditions.

[0003] The main purpose of a vertical / horizontal CNC rotary table is to switch orientations. The design of the rotary table needs to allow it to switch between vertical and horizontal modes according to actual needs, thereby adapting to different experimental and processing requirements. However, the current design of vertical / horizontal rotary tables is relatively complex. They mainly switch orientations by rotation, but because the rotary table itself is quite heavy, rotating and switching is inconvenient and affects its use. Utility Model Content

[0004] The purpose of this invention is to provide a turntable that can be used both vertically and horizontally, which has a simple and practical structure and high switching efficiency.

[0005] The technical solution is as follows:

[0006] A rotating platform that can be used both upright and horizontally includes:

[0007] outer shell;

[0008] A worktable is rotatably inserted into the upper surface of the outer casing;

[0009] The transmission assembly is rotatably inserted inside the outer shell. Both the transmission assembly and the turntable are horizontally arranged, and the transmission assembly and the turntable are connected by a transmission.

[0010] The driving component is located on the outer wall of the housing, and the driving output end of the driving component is connected to the transmission assembly, so that the working turntable is driven to rotate by the driving component.

[0011] It also includes several quick-release feet, which are vertically distributed in a mirror-symmetrical manner on opposite sides of the outer shell. The quick-release feet are fixedly connected to the outer side wall of the outer shell by a snap-fit ​​method.

[0012] In addition, the above embodiments of this utility model may also have the following additional technical features:

[0013] According to one embodiment of the present invention, the quick-release support leg includes:

[0014] The mounting body has an upper part on one side that extends outward to form a plug-in part, and a slot is recessed on the lower part of one side of the outer shell and opened along its length direction. The plug-in part can slide into the slot from one side of the slot, and the plug-in part and the slot are in clearance fit.

[0015] A support body is vertically mounted on the mounting body to raise the lower surface of the outer shell.

[0016] The gap fit design between the connector and the slot allows the connector to slide in and out of the slot easily, reducing frictional resistance and making operation smoother.

[0017] In one embodiment, the support body and the mounting body are connected by a threaded connection. The top end of the support body extends upward through the upper surface of the mounting body, and a limiting nut is threadedly connected to the upper part of the support body, abutting against the mounting body. The threaded connection allows for fine-tuning of the height of the support body by rotating it, thereby precisely adjusting the levelness or overall height of the turntable.

[0018] Furthermore, a pad is provided at the bottom end of the support. The pad increases the contact area between the support and the ground, preventing the legs from sliding or sinking on smooth or soft surfaces (such as workshop floors).

[0019] In one embodiment, the depth of the slot is not less than the thickness of the insertion portion. The slot depth is sufficient to accommodate the entire insertion portion, avoiding loose connections caused by partial exposure or incomplete insertion of the insertion portion, and ensuring full contact between the support leg and the housing.

[0020] Compared with the prior art, the advantages of this utility model are as follows: the quick-release legs are connected by a snap-fit ​​method, so that the installation and disassembly of the legs do not require tools or complicated operations, and can be completed with a simple push-in or pull-out action; when it is necessary to switch from vertical processing to horizontal processing (or vice versa), the user only needs to quickly disassemble or install the legs, and then flip the turntable, avoiding the cumbersome operation of rotating the entire turntable, saving time and labor, and improving work efficiency.

[0025] 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.

[0026] This utility model embodiment proposes a vertical / horizontal dual-purpose rotary table, mainly used in machining centers. It should be noted that this embodiment's vertical / horizontal dual-purpose rotary table is an improved design of a traditional rotary table, but it is still based on the design principles of a traditional rotary table. That is to say, this embodiment does not make any corresponding improvements to the working principle or operation mode of the rotary table. For example, the installation and transmission methods of components such as the working rotary table, transmission assembly, and drive components are all based on existing technology, such as the rotary table mechanism and machining center disclosed in Chinese Utility Model Patent No. 202322931372.3, paragraphs 0037-0050 of its specification and its accompanying drawings. Figures 1-3 The internal design of traditional turntables has been made public.

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, the vertical / horizontal dual-purpose turntable of this embodiment includes a housing 100. A working turntable 200 is rotatably inserted into the upper surface of the housing 100. A transmission assembly 300 is rotatably disposed inside the housing 100. Both the transmission assembly 300 and the working turntable 200 are horizontally arranged, and a transmission connection is established between them. A driving member 400 is disposed on the outer wall of the housing 100. The driving output end of the driving member 400 is connected to the transmission assembly 300, and the driving member 400 drives the working turntable 200 to rotate. The internal structure of the housing is not described in detail in this embodiment.

[0029] The key improvement of this utility model lies in the addition of several quick-release feet 500. Typically, multiple quick-release feet 500 are provided, vertically distributed in a mirror-symmetrical manner on opposite sides of the outer casing 100. In this embodiment, two quick-release feet 500 are provided on the lower part of each side of the outer casing 100, for a total of four, to provide optimal stability. The quick-release feet 500 are fastened to the outer side wall of the outer casing 100 using a snap-fit ​​mechanism for quick fixation and separation.

[0030] Specifically, the quick-release leg 500 includes a mounting body 510 and a support body 520.

[0031] The mounting body 510 is typically a single piece or plate-like structure, made of steel or high-strength aluminum alloy. A horizontally extending outward portion 511 is formed on the upper side of one side of the mounting body 510. The shape of this insertion portion 511 matches the slot 110 provided on the housing 100. The slot 110 is located along the length of the housing and at the lower side of one side of the housing; the slot may also be rectangular or dovetail-shaped. The thickness of the insertion portion 511 is almost equal to the width of the slot 110, allowing the insertion portion 511 to slide stably into the slot 110 from one side (open end), with a clearance fit. This clearance fit ensures smooth installation while preventing excessive wobbling. Preferably, the depth of the slot 110 is not less than the thickness of the insertion portion 511 to ensure that the insertion portion 511 can be fully embedded in the slot 110, obtaining sufficient contact support area and ensuring reliable connection.

[0032] The support body 520 is vertically mounted on the mounting body 510. When the quick-release support leg 500 is inserted into the slot 110 through the plug part 511 and fixed, the support body 520 is located below the outer shell 100, thereby lifting the lower surface of the outer shell 100 off the ground or the machine tool worktable. The support body 520 is usually a solid or hollow cylindrical rod, and its lower end is used for support and load bearing.

[0033] Working principle:

[0034] When the CNC machine tool needs to perform vertical machining, the worktable 200 is in a vertical rotation state (C-axis function). At this time, the quick-release support 500 does not need to be installed, and the outer shell 100 can be placed directly on the machine tool worktable through its lower surface or fixed with a standard fixture.

[0035] When it is necessary to switch to horizontal machining (B-axis function), the operator slides the four quick-release legs 500 into the slots 110 on both sides of the housing 100. Since it is a clearance fit snap-fit ​​method, the installation process is quick and easy, and no tools are required. After installation, the turntable is flipped over so that the working turntable 200 is in a horizontal rotation state, and the support body 520 steadily supports the entire turntable.

[0036] Conversely, when switching from horizontal to vertical, simply pull the quick-release leg 500 out of the slot 110 laterally, which is equally convenient.

[0037] This embodiment avoids the inconvenience of needing to rotate the entire heavy turntable in the prior art by using a simple snap-fit ​​quick-release support leg 500, greatly simplifying the vertical-to-horizontal switching operation, improving work efficiency, and reducing the labor intensity of operators; at the same time, the mirror-symmetrically distributed support legs ensure the stability of the support and guarantee the processing accuracy.

[0038] Example 2

[0039] Based on the basic structure of Example 1, this example further improves the design of the quick-release legs.

[0040] like Figure 3 As shown, the support body 520 and the mounting body 510 are connected by a threaded connection, and a pad 540 is provided at the bottom end of the support body 520. Specifically, a vertical threaded through hole is opened in the center of the mounting body 510. The support body 520 is a solid or hollow cylindrical rod with external threads machined on its body. The support body 520 is screwed into the threaded through hole of the mounting body 510 through its external threads, so that the top end of the support body 520 penetrates the upper surface of the mounting body 510.

[0041] By rotating the support body 520 clockwise or counterclockwise, the extension length of the support body 520 relative to the mounting body 510 can be precisely adjusted, thereby achieving fine adjustment of the support height of a single leg. This design helps to compensate for the unevenness of the machine tool table or the ground. It ensures that when the turntable is supported in a horizontal position, the end face of the worktable 200 is in a precise vertical position, thereby ensuring machining accuracy.

[0042] To reliably lock the adjusted height and prevent uncontrollable rotation and loosening of the support body 520 under machine tool vibration, a limiting nut 530 is tightened at the top of the support body 520 (i.e., the threaded part extending from the upper surface of the mounting body 510). After the support body 520 rotates to the required height, the limiting nut 530 is tightened downwards with a wrench or other tools, so that its lower end face generates strong friction and abutment force with the upper surface of the mounting body 510. This simple mechanical locking method constitutes an effective anti-loosening mechanism, ensuring the long-term stability of the support height.

[0043] At the bottom end of the support body 520, a pad 540 is fixedly installed. The pad 540 is preferably made of a material with a high coefficient of friction and a certain elasticity, such as rubber, polyurethane or engineering plastic. The pad 540 can be reliably installed at the bottom of the support body 520 by means of threaded connection, bonding or interference fit.

[0044] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
