Abstract
Description
Technical Field
[0001] This utility model relates to the field of engraving machine equipment technology, specifically to a pin beam moving and locking device for an engraving machine. Background Technology
[0002] In the field of engraving, workpieces are often heavy and vary in length. To ensure stability and safety during the processing, it is often necessary to use an ejector beam for auxiliary fixation. The ejector beam must be able to flexibly adjust its position according to the actual length of the workpiece to ensure effective support for workpieces of different specifications, preventing displacement or vibration during processing, which could affect processing accuracy or even damage the equipment.

[0007] A further improvement of this utility model is that the limiting block is fixedly mounted on the ejector pin beam.
[0008] A further improvement of this utility model is that the nut I is disposed between the C-shaped structures.
[0009] A further improvement of this utility model is that the locking hook includes a screw section and a C-shaped section, the C-shaped section being sleeved on the guide rail.
[0010] A further improvement of this utility model is that the locking hook is integrally formed.
[0011] A further improvement of this utility model is that the roller bracket includes a bracket body, which is elongated, and at least two roller assemblies are arranged along the length of the bracket body.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present invention.
[0020] This utility model provides a movable locking device for a center beam of an engraving machine. The center beam is used to move back and forth along a guide rail. This movable locking device has both movable and locking functions, enabling both movement and locking of the center beam. Furthermore, a preset number of movable locking devices can be set on the center beam according to actual needs. This utility model does not specifically limit this; for example, such as... Figure 1 As shown, two movable locking devices can be installed.
[0021] like Figures 1-4 As shown, the locking device for the movement of the ejector beam in a carving machine includes: Guide rail seat 2, which is located below the ejector pin beam 1, such as Figure 4 As shown, it includes: a base 201 fixedly connected to the ejector beam 1, and two support plates 202 oppositely disposed on the base 201. Each support plate 202 has a V-groove 203 at its bottom that matches the auxiliary surface of the guide rail 4. The guide rail 4 has the following structure: Figure 1As shown, it is H-shaped, and the upper plane includes a bearing surface in the middle and auxiliary surfaces on both sides of the auxiliary surface; by setting the V-groove 203, the contact part between the guide rail seat 2 and the guide rail 4 is set as a mother-child structure; Roller bracket 3, such as Figures 1-3 As shown, it is disposed between the two support plates 202, and at least two rollers 301 are provided on it. Each roller 301 is used to move back and forth along the upper bearing face of the guide rail 4. The contact portion of the roller 301 with the guide rail 4 has a mother-child structure with the guide rail 4; in addition, as Figure 2 As shown, the roller bracket 3 is provided with a nut II 8 that is fixedly connected to the locking hook; The locking hook 5 is fitted at the bottom onto the guide rail 4, and at the top it passes through the roller bracket 3, nut II 8, guide rail seat 2, and ejector pin beam 1 in sequence before being fixed by nut I 6. The nut I 6 is used to loosen the locking hook 5 when rotating in the first direction, so that the guide rail seat 2 moves upward and separates from the guide rail 4, and the roller 301 contacts the guide rail 4 to facilitate the movement of the ejector beam 1; and when rotating in the second direction, it tightens the locking hook 5, so that the guide rail seat 2 moves downward and the V-groove 203 fits against the guide rail 4 to fix the ejector beam 1.
[0022] In this utility model, the first direction and the second direction are not specifically limited. For example, the first direction is clockwise and the second direction is counterclockwise; or the first direction is counterclockwise and the second direction is clockwise. In the following description, this utility model will use the first direction as clockwise and the second direction as counterclockwise.
[0023] The ejector beam moving locking device for a carving machine provided in this embodiment of the utility model allows for easy movement of the ejector beam during operation. When the ejector beam needs to move, simply turn nut I clockwise to loosen the locking hook 5 and separate the guide rail seat 2 from the guide rail 4, allowing the roller 301 to contact the guide rail 4, thereby raising the ejector beam 1 and easily pushing it. When the ejector beam 1 needs to stabilize the workpiece, turn nut I 6 counterclockwise to tighten the locking hook 5, causing the guide rail seat 2 to fall down. The V-groove of the guide rail seat 2 fits tightly against the guide rail 4, and the device automatically positions itself using this mother-and-child structure.
[0024] The pin beam moving and locking device for a carving machine provided in this embodiment of the utility model consists of a guide rail seat 2 fixedly connected to the pin beam 1, a roller bracket 3 located inside the guide rail seat 2, a roller 301 and a nut Ⅱ 8 set on the roller bracket 3, and a locking hook 5 with its bottom sleeved on the guide rail 4, its top extending upward through the aforementioned structure and fixed by the nut Ⅰ 6. Only the rotation of the nut Ⅰ 6 is needed to achieve both moving and locking functions. It is not only simple in structure and convenient to operate, but also, by setting the V-groove 203 and the roller 301, there is no need to modify the guide rail 4 or perform subsequent maintenance on the guide rail 4, greatly saving on usage costs.
[0025] In order to achieve the aforementioned function when rotating nut I 6, as follows: Figure 1 and Figure 2 As shown, it also includes a limiting block 7, which forms a C-shaped structure with the ejector beam 1, and a nut I 6 is disposed between the C-shaped structures. Thus, when the nut I 6 rotates, it moves axially within the C-shaped structure, thereby causing the screw to move axially in the same direction as the nut I 6, which in turn moves the guide rail seat 2, thereby achieving the aforementioned movement and locking.
[0026] The structure of the roller bracket 3 and the locking hook 5 will be further explained below.
[0027] Regarding the structure of the roller bracket 3, in one possible implementation, such as Figure 5 As shown, the roller bracket 3 includes a bracket body 302, which is elongated, and at least two roller assemblies are arranged along the length of the bracket body 302; each roller assembly includes two opposing side plates 303, and a roller 301 is rotatably arranged between the two side plates 303.
[0028] The number of roller assemblies can be set as needed, for example, such as Figure 1 and Figure 5 As shown, two roller assemblies are provided, located at both ends of the bracket body 302 respectively; a screw hole is provided at the center of the bracket body 302, and the nut II 8 is fixedly provided above the screw hole.
[0029] Regarding the structure of locking hook 5, in one possible implementation, such as Figure 6 As shown, it includes a screw section 501 and a C-shaped section 502, with the C-shaped section 502 sleeved on the guide rail 4.
