Abstract
Description
[Technical Field]
[0001] This utility model mainly relates to a frame structure of a CNC spinning machine. [Background Technology]
[0002] CNC spinning machines generate chips during processing. If these chips enter the slide rails, they can alter the clearance between components, leading to unstable movement. A large accumulation of chips between sliding parts can cause jamming, preventing the machine from operating normally. For example, excessive chips between the lead screw and nut in the spinning machine may prevent the lead screw from rotating, affecting the machine's normal operation. To prevent chip ingress, we propose a frame structure design for the CNC spinning machine. [Utility Model Content]
[0003] To solve at least one of the above problems, this utility model proposes a new structural solution. The frame structure of this CNC spinning machine adopts the following technical solution:
[0004] A CNC spinning machine frame structure includes a machine base, a bed, a spindle box, a tailstock, and a support plate; the bed is fixed to the machine base, the spindle box and the tailstock are mounted on the bed, and the spindle box and the tailstock are respectively located at both ends of the bed;
[0005] The bed is provided with a first guide rail, and the tray slides on the first guide rail; the middle part of the bed has a groove, the first guide rail is respectively located on both sides of the groove, the groove is provided with a drive motor, and the drive motor is connected to the tray through a shaft to drive the tray to move along the first guide rail;
[0006] Sheet metal covers are installed at both ends of the pallet. The spindle box and the tail top are provided with clearance positions so that the sheet metal covers can pass into the clearance positions as the pallet moves, so that the sheet metal covers keep covering the first guide rail.
[0007] Preferably, the bed frame has several empty spaces, which are located at the bottom of the bed frame and below the grooves.
[0008] Preferably, the two ends of the bed extend outwards to form support portions, and the spindle box and tailstock are mounted on the support portions at corresponding positions to be fixed to the bed.
[0009] Preferably, the pallet is equipped with an adjustment motor and a working plate. The pallet is equipped with a second guide rail, and the working plate slides on the second guide rail. The second guide rail and the first guide rail are set in perpendicular directions. The adjustment motor is connected to the working plate through a shaft so as to adjust the position of the working plate.
[0010] Preferably, the work plate is equipped with a protective cover to prevent foreign objects from entering the tray.
[0011] The beneficial effects of this utility model compared with the prior art are:
[0012] In this structure, the bed is an independent component, facilitating individual machining and forming. Legs extend from the bed to both sides, increasing the contact area between the bed and the machine base and improving bed stability. To prevent cutting chips from entering the bed, sheet metal covers are installed on both sides of the support plate to conceal the bed and prevent chips from falling in. The sheet metal covers are fixed to the support plate to move with it, maintaining coverage of the bed. Clearances are provided in the spindle box and tailstock for the sheet metal covers to pass through and cooperate with their movement. Simultaneously, a protective cover is also installed on the work plate to prevent chips from entering the support plate. The cooperation between the protective cover and the sheet metal covers effectively limits the entry of chips into the slide rails and grooves, thus ensuring smooth transmission. It features a simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

[0017] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0019] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] The preferred embodiment provided by this utility model is as follows: Figures 1-4 As shown, a CNC spinning machine frame structure includes a machine base 1, a bed 2, a spindle box 3, a tailstock 4, and a support plate 5; the bed 2 is fixed to the machine base 1, the spindle box 3 and the tailstock 4 are installed on the bed 2, and the spindle box 3 and the tailstock 4 are respectively located at both ends of the bed 2.
[0021] The bed 2 is provided with a first guide rail 21, and the tray 5 is slidably connected to the first guide rail 21; the middle part of the bed 2 has a groove 22, the first guide rail 21 is respectively provided on both sides of the groove 22, the groove 22 is provided with a drive motor 23, the drive motor 23 is connected to the tray 5 through a shaft to drive the tray 5 to move along the first guide rail 21; the shaft is preferably a lead screw.
[0022] Sheet metal covers 51 are installed at both ends of the pallet 5. Both the spindle box 3 and the tail top 4 are provided with clearances 41 so that the sheet metal covers 51 can pass through the clearances 41 as the pallet 5 moves, keeping the sheet metal covers 51 covering the first guide rail 21 and preventing debris from falling into the groove 22 and the slide rail during the operation of the spinning machine, thus affecting the smooth movement of the pallet 5. The clearances 41 pass through the components to allow the sheet metal covers 51 to pass through.
[0023] The bed 2 has several recessed spaces 24 located at its bottom and below the grooves 22. The sides of the grooves 22 are the main load-bearing areas of the bed 2. To maintain support, these areas should be solid. Therefore, to reduce the weight of the bed 2, several recessed spaces 24 are arranged at its bottom, thereby reducing weight, lowering costs, and facilitating assembly. Support portions 25 extend outwards from both ends of the bed 2. The spindle box 3 and tailstock 4 are mounted on the support portions 25 at corresponding positions to secure them to the bed 2.
[0024] The pallet 5 is equipped with a positioning motor 52 and a working plate 53. The pallet 5 has a second guide rail 54, and the working plate 53 is slidably connected to the second guide rail 54 via a slide block. The second guide rail 54 and the first guide rail 21 are perpendicular in their orientation. The positioning motor 52 is connected to the working plate 53 via a shaft, so as to adjust the position of the working plate 53. The working plate 53 is equipped with a protective cover 55 to restrict foreign objects from entering the pallet 5, to prevent cutting debris from falling into the pallet 5, and to ensure that the positioning motor 52 can smoothly drive the working plate 53 to move.
[0025] CNC spinning machines generate debris during processing. If this debris enters the slide rails, it can alter the clearance between components, leading to unstable movement. A large accumulation of debris between sliding parts can cause them to jam, preventing the equipment from operating normally. For example, excessive debris between the lead screw and nut in a spinning machine may prevent the lead screw from rotating, affecting the machine's normal operation.
[0026] In this structure, the bed 2 is an independent component, facilitating individual machining and forming. Legs 56 extend from both sides of the bed 2, increasing the contact area between the bed 2 and the machine base 1 and improving the stability of the bed 2. To prevent cutting debris from entering the bed 2, sheet metal covers 51 are installed on both sides of the support plate 5 to cover the bed 2 and prevent debris from falling in. The sheet metal covers 51 are fixed to the support plate 5 to move with it, maintaining coverage of the bed 2. The spindle box 3 and tailstock 4 both have clearances 41 for the sheet metal covers 51 to pass through, facilitating their movement. Simultaneously, to prevent debris from entering the support plate 5, a protective cover 55 is also installed on the work plate 53. The cooperation between the protective cover 55 and the sheet metal covers 51 effectively restricts debris from entering the slide rails and grooves 22, thereby ensuring smooth transmission.
