Abstract
Description
[Technical Field]
[0001] This utility model mainly relates to a chip-proof sliding bolster structure for a spinning machine. [Background Technology]
[0002] CNC spinning machines generate chips during processing. If these chips enter the guide 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 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 anti-chip slide structure of this spinning machine adopts the following technical solution:
[0004] A chip-proof sliding ram structure for a spinning machine includes a bed, guide rails, a slide, and a telescopic guide rail cover. The bed is equipped with a motor, which is connected to the slide via a lead screw. Guide rails are installed on both sides of the bed, and the slide slides along the guide rails. The slide is driven by the motor to move along the guide rails.
[0005] Telescopic guide rail cover plates are installed on the guide rail to cover the guide rail. The telescopic guide rail cover plates include a first cover plate, a connecting cover plate, and a last cover plate. The first cover plate is locked to the slide plate, the last cover plate is locked to the guide rail, and the connecting cover plate is located between the first cover plate and the last cover plate. The first cover plate, the connecting cover plate, and the last cover plate are interconnected to generate linkage.
[0006] Preferably, a first locking block extends vertically from the top of the first end of the first cover plate, and a second connecting block extends horizontally from the bottom of the end of the last cover plate.
[0007] Preferably, a scraper extends downward at the end of the first cover plate, and the scraper of the first cover plate is attached to the end face of the connecting cover plate.
[0008] Preferably, one end of the connecting cover plate extends downward at an angle to form a scraper, and the other end extends upward at an angle to form a top plate.
[0009] Preferably, one end of the end cover plate extends upward at an angle to form a top piece, and the second connecting block is located at the other end.
[0010] Preferably, the end of the end cover plate with the second connecting block has an opening for the guide rail to enter.
[0011] Preferably, rubber sleeves are bonded to the ends of the scraper and the top plate.
[0012] The beneficial effects of this utility model compared with the prior art are:
[0013] To prevent cutting debris from entering the guide rail, this solution incorporates a telescopic guide rail cover. This cover includes a first cover plate, a connecting cover plate, and a final cover plate. Several connecting cover plates are used, and the dimensions of the first, connecting, and final cover plates are appropriately set to create a stepped connection for easy extension and retraction. The first cover plate is locked to the sliding plate, and the final cover plate is locked to the guide rail. The connecting cover plate is positioned between the first and final cover plates. When the sliding plate moves, it drives the first cover plate, which in turn drives the connecting cover plates to unfold, thus covering the guide rail and preventing debris from entering. Furthermore, to prevent debris from entering between the components of the telescopic guide rail cover, the connecting cover plate and the first cover plate are equipped with inclined scrapers. These scrapers remove debris from the surface of the telescopic guide rail cover during movement, ensuring smooth unfolding and retraction. This design 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 1-3 As shown, a chip-proof sliding bolster structure for a spinning machine includes a bed 1, a guide rail 2, a slide 3, and a telescopic guide rail cover 4. The bed 1 is equipped with a motor, which is connected to the slide via a lead screw. The guide rails 2 are installed on both sides of the bed 1. The slide 3 is slidably connected to the guide rails 2 via a slide block. The slide is driven by the motor to move along the guide rails 2.
[0021] Telescopic guide rail cover 4 is installed on guide rail 2 to cover guide rail 2. Telescopic guide rail cover 4 can be installed on both sides of slide plate 3 to completely cover guide rail 2. Telescopic guide rail cover 4 includes first cover plate 5, connecting cover plate 6, and last cover plate 7. First cover plate 5 is locked to slide plate 3, last cover plate 7 is locked to guide rail 2, connecting cover plate 6 is located between first cover plate 5 and last cover plate 7, and first cover plate 5, connecting cover plate 6, and last cover plate 7 are interconnected to generate linkage.
[0022] A first locking block 51 extends vertically from the top of the first end of the first cover plate 5, and a second connecting block 52 extends horizontally from the bottom of the end of the last cover plate 7. Both the first locking block 51 and the second connecting block 52 are provided with connecting holes. Screws are inserted into the connecting holes to connect to the corresponding components to fix the first cover plate 5 and the last cover plate 7 together. The end of the last cover plate 7 with the second connecting block 52 has an opening 53 for the guide rail 2 to enter.
[0023] A scraper 53 extends downward at the end of the first cover plate 5, and the scraper 53 is attached to the end face of the connecting cover plate 6. A scraper 53 extends downward at one end of the connecting cover plate 6, and a top plate 54 extends upward at the other end. A top plate 54 extends upward at one end of the last cover plate 7, and a second connecting block 52 is located at the other end. The top plate 54 abuts against the scraper 53, facilitating the movement of adjacent components. Rubber sleeves 55 are bonded to the ends of the scraper 53 and the top plate 54. Since the first cover plate 5, connecting cover plate 6, and last cover plate 7 are all made of metal, the addition of rubber sleeves 55 prevents collisions and scratches.
[0024] During the CNC spinning process, debris is generated. If this debris enters the space between the guide 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 of the spinning machine may prevent the lead screw from rotating, affecting the normal operation of the equipment.
[0025] To prevent cutting debris from entering the guide rail 2, this solution adds a telescopic guide rail cover plate 4 to the guide rail 2. The telescopic guide rail cover plate 4 includes a first cover plate 5, a connecting cover plate 6, and a last cover plate 7. There are several connecting cover plates 6. The dimensions of the first cover plate 5, the connecting cover plate 6, and the last cover plate 7 are set accordingly so that the first cover plate 5, the connecting cover plate 6, and the last cover plate 7 are connected in a stepped manner to facilitate telescopic movement. The first cover plate 5 is locked to the slide plate 3, the last cover plate 7 is locked to the guide rail 2, and the connecting cover plate 6 is located between the first cover plate 5 and the last cover plate 7. When the slide plate 3 moves, it will drive the first cover plate 5 and drive the connecting cover plate 6 to unfold in conjunction to keep the guide rail 2 covered and prevent debris from entering the guide rail 2. Meanwhile, to prevent debris from entering between the components of the telescopic guide rail cover plate 4, the connecting cover plate 6 and the first cover plate 5 are provided with inclined scrapers 53. The scrapers 53 remove debris from the surface of the telescopic guide rail cover plate 4 during the movement, so as to keep the telescopic guide rail cover plate 4 unfolding and retracting smoothly.
