Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically to a guide rail fixing structure and a cutting machine. Background Technology

[0002] In existing cutting machines, the guide rails are fixed to the cutting platform using a clamp. The clamp consists of two pressure blocks, which are bolted to the platform. Each pressure block has a semi-circular hole; the two blocks work together to clamp the guide rail, thus fixing its end. This fixing method has some drawbacks. Because two pressure blocks are needed to hold the guide rail, it is difficult to accurately fix the guide rail's position when the pressure blocks wear or there are significant machining errors. This makes it difficult to adjust the two guide rails to a parallel state. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a guide rail fixing structure and a cutting machine, which can not only fix the guide rail, but also make precise adjustments to the position of the guide rail, thereby improving the accuracy of the equipment.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a guide rail fixing structure, comprising:

[0005] A positioning plate having stepped holes, the stepped holes including threaded holes and limiting holes with a diameter larger than that of the threaded holes, wherein the axis of the threaded holes and the axis of the limiting holes are collinear;

[0006] The guide rail body has a flat groove at its end, and a through hole is formed in the flat groove. The diameter of the through hole is larger than the diameter of the limiting hole.

[0007] A connecting assembly, comprising a bolt and an adjusting sleeve; the adjusting sleeve is inserted into a limiting hole for adjusting the position of the guide rail body on the positioning plate; one end of the bolt passes through the adjusting sleeve and the limiting hole and is threaded into a threaded hole.

[0008] Preferably, the adjusting sleeve includes a first sleeve and a second sleeve, the outer diameter of the second sleeve is larger than the outer diameter of the first sleeve, the second sleeve is eccentrically fixed to one end of the first sleeve, the first sleeve is inserted into the limiting hole, and the second sleeve is inserted into the through hole.

[0009] Preferably, the outer wall of the second sleeve away from the first sleeve has an outward protrusion.

[0010] Preferably, a first anti-slip pad is fitted onto the second sleeve between the protruding part and the flat groove.

[0011] Preferably, the edges of the protruding portion are polygonal.

[0012] Preferably, a second anti-slip washer is fitted on the stud between the bolt head and the protruding part.

[0013] A cutting machine includes the aforementioned guide rail fixing structure.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention designs a positioning plate and a connecting assembly, and creates a flat groove at the end of the guide rail body. The flat groove at the end of the guide rail body can be placed on the surface of the positioning plate, and then the connecting assembly is used to fix the guide rail body and the positioning plate together. The adjusting sleeve in the connecting assembly can fine-tune the position of the guide rail body on the positioning plate, thereby compensating for positional errors caused by welding or drilling processes, and accurately adjusting the two guide rail bodies to be parallel. The design of the polygonal protrusion facilitates quick fine-tuning of the position of the guide rail body using tools, improving work efficiency and also facilitating later maintenance and repair.

[0026] 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.

[0027] Example 1:

[0028] like Figures 1 to 7 As shown, Embodiment 1 of this utility model provides a guide rail fixing structure, mainly composed of a positioning plate 1, a guide rail body 5, and connecting components. In this embodiment, two positioning plates 1 are designed to fix two guide rail bodies 5, with each guide rail body 5 having its two ends connected to the two positioning plates 1 respectively. First, the positioning plate 1 serves as the mounting base and needs to be fixed to the equipment on which the guide rail is to be installed. Two stepped holes 2 are formed on the positioning plate 1. Figure 7 As shown, the stepped hole 2 includes two parts: a threaded hole 3 and a limiting hole 4. The two are collinear, and the diameter of the limiting hole 4 is larger than the diameter of the threaded hole 3.

[0029] The connecting assembly includes bolt 8 and adjusting sleeve 9. Bolt 8 is used for fastening the connection, while adjusting sleeve 9 allows for fine adjustment of the position of the end of the guide rail body 5 on the positioning plate 1. Figure 4 As shown, the adjusting sleeve 9 is divided into two parts: the first sleeve 10 and the second sleeve 11. The outer diameter of the second sleeve 11 is larger than that of the first sleeve 10, and the second sleeve 11 is eccentrically fixed to one end of the first sleeve 10. The interiors of the first sleeve 10 and the second sleeve 11 are connected, and the screw part of the bolt 8 can pass through the first sleeve 10 and the second sleeve 11.

[0030] Flat grooves 6 are machined on both sides of the guide rail body 5, and through holes 7 are drilled in the flat grooves 6. The diameter of the through holes 7 is specially designed to be larger than that of the limiting hole 4. This dimensional difference allows the second sleeve 11 of the adjusting sleeve 9 to be partially inserted into the through hole 7. Figure 7As shown, the first sleeve 10 can be inserted into the limiting hole 4. When the adjusting sleeve 9 is rotated, the adjusting sleeve 9 can rotate around the axis of the limiting hole 4. Since the axis of the second sleeve 11 is deviated from the axis of the limiting hole 4, the second sleeve 11 can move the end of the guide rail body 5 within a small range, thereby realizing the fine adjustment of the position of the guide rail body 5 on the positioning plate 1, thus compensating for the error caused by the welding or hole-opening process, and making the two guide rail bodies 5 parallel.

[0031] The screw part of the bolt 8 can pass through the first sleeve 10 and the limiting hole 4 and be threaded to the threaded hole 3, so that the screw head of the bolt 8 can fasten the adjusting sleeve 9 and the guide rail body 5 to the positioning plate 1.

[0032] With the above settings, when the adjusting sleeve 9 is rotated, the position of the guide rail body 5 on the positioning plate 1 can be finely adjusted, which facilitates the calibration of the position of the guide rail body 5 on the equipment and ensures that the two guide rail bodies 5 are parallel.

[0033] Example 2:

[0034] Based on Embodiment 1, to further enhance the stability of the connection and prevent loosening, an outward protrusion 12 is added to the outer wall of the end of the second sleeve 11 furthest from the first sleeve 10. The size of the outward protrusion 12 is larger than the diameter of the through hole 7. This design not only increases the contact area between the adjusting sleeve 9 and the guide rail body 5, improving friction, but also facilitates the use of tools to rotate the adjusting sleeve 9. A first anti-slip pad 13 is also fitted onto the second sleeve 11 between the outward protrusion 12 and the flat groove 6, further strengthening the stability of the connection and preventing the guide rail body 5 from shifting due to vibration.

[0035] The edge of the protruding part 12 is designed as a polygon. This shape design allows the adjusting sleeve 9 to be firmly clamped with tools such as wrenches, making it easy to rotate the adjusting sleeve 9 to make fine adjustments to the guide rail body 5.

[0036] In addition, a second anti-slip washer 14 is fitted onto the stud portion between the bolt head and the protruding part 12 of bolt 8. This additional anti-slip measure effectively reduces the risk of bolt 8 loosening, ensuring the long-term stability and safety of the entire fixing structure.

[0037] Example 3:

[0038] Based on the above embodiments, this utility model also proposes a cutting machine, wherein the guide rail of the cutting machine is installed on the frame of the cutting machine through the above-mentioned guide rail fixing structure, and the workpiece clamp or the cutting machine body can be slidably installed on the guide rail.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
