This method is not only time-consuming and laborious, but also difficult to ensure the precise fit between the guide rail and the machine frame. Especially in different models, the distance between the side guide rails may vary, making the traditional fixation method difficult to adapt to various situations, which not only increases the difficulty of manual installation, but also affects the overall work efficiency.

[0022] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model. However, the present utility model is not limited to these embodiments.

[0023] As Figures 1 to 3 shown, a tooling structure assembly for a side guide rail to closely fit with a machine frame 1 according to the present utility model includes: a hollow steel pipe 2 placed between a first side guide rail 10 and a second side guide rail 11 on the machine frame 1, and the axial direction of the hollow steel pipe 2 is perpendicular to both the first side guide rail 10 and the second side guide rail 11; a first ejector rod 30 and a second ejector rod 31, which are respectively movably arranged at both ends of the hollow steel pipe 2. The first ejector rod 30, the second ejector rod 31, and the hollow steel pipe 2 are coaxially arranged, and both the first ejector rod 30 and the second ejector rod 31 can move relative to the hollow steel pipe 2 along the axial direction and respectively movably abut against the first side guide rail 10 and the second side guide rail 11; an adjusting member 4, which is movably connected to the first ejector rod 30 and the second ejector rod 31, and the adjusting member 4 is used to drive the first ejector rod 30 or the second ejector rod 31 to contract or extend out of the hollow steel pipe 2 along the axial direction; the first ejector rod 30 or the second ejector rod 31 can extend out of the hollow steel pipe 2 along the axial direction when the adjusting member 4 rotates, so that both the first side guide rail 10 and the second side guide rail 11 in a symmetric or asymmetric position can be tightly attached to the machine frame 1.

[0024] This solution is mainly to achieve the cooperation between the side guide rail and the machine frame 1. Specifically, as Figures 1 to 2 shown, in this embodiment, a first side guide rail 10 and a second side guide rail 11 are provided on the machine frame 1. When a worker places the hollow steel pipe 2 between the two side guide rails, at this time, the rotation of the adjusting member 4 can drive the first ejector rod 30 and the second ejector rod 31 to respectively extend out of the hollow steel pipe 2. It should be noted that during the installation process, the worker can pre-abut any one of the first ejector rod 30 and the second ejector rod 31 against one of the side guide rails through the adjusting member 4. After maintaining a certain stability, then use the adjusting member 4 to abut the other ejector rod against the side guide rail when it moves and extends. Relying on the combined action of the adjusting members 4 on the two ejector rods, the first ejector rod 30 and the second ejector rod 31 can simultaneously tightly attach the first side guide rail 10 and the second side guide rail 11 on both sides to the machine frame 1 to ensure subsequent normal assembly. As high-strength screws fix the side guide rail on the machine frame 1, a tight fit between the side guide rail and the machine frame 1 is achieved. The overall tooling structure is relatively simple, with low manufacturing cost, and at the same time brings great convenience to the worker during operation, improving the overall work efficiency.

[0025] External threads 320 are formed on both the first ejector rod 30 and the second ejector rod 31, and the adjusting member 4 is an adjusting nut, and the adjusting nut is threadedly connected to the external threads 320.

[0026] As Figure 2As shown, this solution mainly relies on the threaded fit between the adjusting nut and the external thread 320, so that the adjusting nut can drive the first ejector rod 30 and the second ejector rod 31 to extend out of the hollow steel pipe 2 along the axial direction during rotation. It should be noted that the external thread 320 in this solution is arranged along the length direction of the ejector rod, and the length of the external thread 320 can be designed according to actual usage requirements. Because of the allowable length of the external thread 320, even when the distances between the first side guide rail 10 and the second side guide rail 11 on both sides of different models are different, it is still possible to rely on the advantage of the thread length, and drive the first ejector rod 30 or the second ejector rod 31 to extend different distances relative to the hollow steel pipe 2 to abut against the side guide rail through the adjusting nut, effectively improving the flexibility of the use of this tooling structure.

[0027] Preferably, the sum of the lengths of the first ejector rod 30 and the second ejector rod 31 in this solution is less than the length of the hollow steel pipe 2. Before using this tooling structure, the first ejector rod 30 and the second ejector rod 31 can be pre-placed into the hollow steel pipe 2. Therefore, the overall length of the hollow steel pipe 2 should be sufficient to accommodate the two ejector rods. With the adjusting members 4 respectively installed on the first ejector rod 30 and the second ejector rod 31, the first ejector rod 30 and the second ejector rod 31 can be freely extended along the directions of the two side guide rails under the rotation of the adjusting members 4. Since the consumable part of this tooling is the adjusting nut, the cost is relatively low and the utilization rate is high. Without damaging the side guide rail, the side guide rail can be reasonably pressed.

[0028] At the ends of the first ejector rod 30 and the second ejector rod 31 away from the hollow steel pipe 2, abutting blocks 321 are provided, and the abutting blocks 321 are movably abutted against the first side guide rail 10 or the second side guide rail 11 to press the first side guide rail 10 or the second side guide rail 11 against the machine frame 1.

[0029] As Figures 2 to 3 shown, abutting blocks 321 are provided at the ends of the first ejector rod 30 and the second ejector rod 31. The diameter of the abutting blocks 321 is larger than the diameter of the ejector rod to increase the contact area when abutting against the side guide rail, ensuring stable and close fit with the machine frame 1. Preferably, in this embodiment, the abutting blocks 321 and the ejector rod can be installed in a detachable connection manner (such as threaded fit) to ensure that the abutting blocks 321 can be replaced in time when worn or damaged, thereby improving the stability of the close fit between the side guide rail and the machine frame 1.

[0030] At one end of the first ejector rod 30 and the second ejector rod 31 close to the abutting block 321, pre-tightening grooves 322 are provided. The bottom wall of the pre-tightening groove 322 is composed of a plurality of inclined planes 322a distributed in a ring and connected to each other for a ring spanner to be movably clamped to tighten or disassemble the first ejector rod 30 or the second ejector rod 31.

[0031] As Figures 2 to 3As shown, in this embodiment, the pre-tightening groove 322 is close to the end of the ejector rod away from the hollow steel pipe 2. When the adjusting member 4 drives the first ejector rod 30 or the second ejector rod 31 to be pre-tightened against the side guide rail on any side in advance, at this time, the adjustable wrench can be movably clamped on the inclined plane 322a. Under the rotation of the adjustable wrench, the ejector rod can further apply a tightening force to the side guide rail, which ensures the smoothness and stability during the tightening process of the other ejector rod. After the inclined planes 322a on both ejector rods are further tightened by the adjustable wrench, the stability of the tight fit between the side guide rail and the frame 1 is effectively ensured. At the same time, after the side guide rail and the frame 1 are firmly fixed by the high-strength screws, the worker can use the adjustable wrench to loosen the first ejector rod 30 and the second ejector rod 31 again, so as to more smoothly retract the first ejector rod 30 and the second ejector rod 31 into the hollow steel pipe 2 along the axial direction under the drive of the adjusting member 4, which brings convenience for both use and disassembly.

[0032] Preferably, an arc transition surface 323 is further formed at the end of the tightening block 321 in this solution, as Figure 3 shown. This arc transition surface 323 can avoid stress concentration on the contact surface between the tightening block 321 and the side guide rail. While improving the aesthetics, it also helps to extend the service life of the tightening block 321. Of course, from an economic perspective, this arc transition surface 323 can also be replaced by a chamfer to facilitate better processing and manufacturing of the tightening block 321 by workers.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, then the directional indication also changes accordingly.

[0034] In addition, in the present invention, descriptions such as "first", "second", "one" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of these features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0035] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model may be understood according to specific circumstances.

[0036] In addition, the technical solutions between various embodiments of the present utility model may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
