Description

Technical Field

[0001] This utility model relates to the field of machine tool guideway technology, specifically a roller-type machine tool sliding guideway structure with close contact. Background Technology

[0002] Machine tools are machines used to manufacture machines, also known as machine tools or machine tools, and are commonly referred to simply as machine tools. They are generally divided into metal cutting machine tools, forging and pressing machine tools, and woodworking machine tools, etc. Machine tools mainly use turning tools to perform turning operations on rotating workpieces. Drills, reamers, taps, dies, and knurling tools can also be used on machine tools for corresponding machining operations.

[0003] Machine tool guideways are key components in machine tools used to guide and support moving parts. They ensure that moving parts of the machine tool (such as the worktable and tool post) can move precisely along a predetermined straight or curved trajectory, thereby guaranteeing machining accuracy and stability.

[0004] A guide rail, also known as a slide rail, linear guide rail, or linear slide rail, is an upgraded version of a linear bearing bracket used in linear reciprocating motion applications. It has a higher rated load than traditional linear bearings and can withstand a certain amount of torque, enabling high-precision linear motion under high load conditions.

[0005] Traditional guide rail structures typically employ internal ball bearings to achieve rolling friction, replacing sliding friction and reducing running resistance. However, due to long-term operation, this causes rolling wear on the balls, a natural wear process. Over extended periods, the outer wall of the balls thins, potentially creating gaps between them and the guide rail, preventing rolling contact. In practical use, this affects the overall operational stability of the guide rail structure, leading to decreased accuracy and insufficient stability. To address this, this invention proposes a roller-type machine tool sliding guide rail structure that maintains long-term stable and tight contact using springs. Utility Model Content

[0006] The purpose of this invention is to provide a roller-type sliding guide structure for machine tools with close contact, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a closely contacting roller-type machine tool sliding guide structure, comprising a guide body, with limiting guide grooves provided on both sides of the guide body's waistline portion, a sliding seat slidably connected to the upper limit of the guide body, and several inner grooves provided on both sides of the inner wall of the sliding seat, a total of four inner grooves, which are distributed mirror-symmetrically among each other, with a spring fixedly installed at the bottom of each inner groove, and a wheel seat fixedly installed at the top of the spring, the wheel seat adopting a side "concave" structure design, with two rollers rotatably installed in each wheel seat via a rotating shaft, the outer wall of the rollers rollingly contacting the side wall of the limiting guide groove, and guide plates fixedly installed on both ends of the outer wall of the sliding seat.

[0008] Preferably, the guide plate adopts a triangular structure design.

[0009] Preferably, threaded holes are provided at the center positions of both sides of the sliding seat.

[0010] Preferably, the two threaded holes are internally threaded with locking pins.

[0011] Preferably, a knob is fixedly installed on the external end of the locking screw, and the knob is provided with anti-slip serrations.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model features a roller that allows for rolling contact with the guide rail body. In actual use, the rolling contact of the roller effectively reduces the overall resistance when the sliding seat moves. Compared with traditional sliding friction, the rolling friction of this utility model has the practical characteristics of low resistance and high smoothness, making it more practical.

[0014] After assembly, the internal spring of the sliding seat of this invention is in a compressed state. After long-term operation, the roller will experience some natural wear, and the roller body will become thinner. Then, through the action of the internal compression spring, the roller will be pushed forward by the spring's compression and rebound after the roller wears out. This ensures that the roller is always in contact with the inner wall of the guide rail body, maintaining a tight rolling contact. In actual use, it is not affected by wear, thus effectively avoiding wear gaps between the roller and the guide rail. This effectively improves the overall running stability of the guide rail and avoids the technical problems of decreased accuracy and insufficient stability caused by wear in traditional ball bearing guide rails. This invention, through the structural cooperation between the spring and the roller, effectively solves the technical problems of insufficient accuracy and stability caused by ball wear. The structure is relatively simple, with low manufacturing cost and difficulty, good practicality, and good economy, making it suitable for implementation. Attached Figure Description

[0023] Please see Figure 1-4The present invention provides an embodiment of a roller-type machine tool sliding guide structure with close contact, including a guide body 1, with limit guide grooves 2 provided on both sides of the waistline portion of the guide body 1, and a sliding seat 3 slidably connected to the upper limit of the guide body 1.

[0024] Please refer to the instruction manual for details. Figure 2 , Figure 3 as well as Figure 4 As shown, several inner grooves 5 are provided on both sides of the inner wall of the sliding seat 3. There are a total of four inner grooves 5, which are distributed in a mirror symmetrical manner. A spring 6 is fixedly installed at the bottom of the inner wall of each inner groove 5, and a wheel seat 7 is fixedly installed at the top of the spring 6. The wheel seat 7 adopts a side "concave" structure design. Two rollers 8 are rotatably installed in each wheel seat 7 through a rotating shaft. The outer wall of the rollers 8 rolls in contact with the side wall of the limiting guide groove 2.

[0025] This structural design allows the rollers 8 to make rolling contact with the guide rail body 1. In actual use, the rolling contact effect of the rollers 8 can effectively reduce the overall resistance when the sliding seat 3 is displaced and sliding. Compared with traditional sliding friction, the rolling friction of this utility model has the practical characteristics of low resistance and high smoothness, making it more practical.

[0026] After assembly, the sliding seat 3 of this invention has a compressed spring 6 inside. After long-term operation, the roller 8 will experience some natural wear, and the wheel body of the roller 8 will become thinner. Then, through the action of the internal compression spring 6, the roller 8 will be pushed forward by the compression and rebound of the spring 6 after wear, so that the roller 8 is always in close contact with the inner wall of the guide rail body 1, and is always in a close rolling contact state. It is not affected by wear during actual use, so it can effectively avoid wear gaps between the roller 8 and the guide rail, thereby effectively improving the overall running stability of the guide rail and avoiding the technical problems of decreased accuracy and insufficient stability caused by wear in traditional ball guide rails. This invention can effectively solve the technical problems of insufficient accuracy and stability caused by ball wear by the above-mentioned structure of spring 6 and roller 8. The structure is relatively simple, the manufacturing cost and difficulty are low, the practicality is good, the economy is good, and it is suitable for implementation.

[0027] In this embodiment, in order to guide the filamentous waste generated during the processing of the guide rail body 1 and prevent the filamentous waste from entering between the guide rail body 1 and the upper surface of the sliding seat 3, guide plates 4 are fixedly installed on the outer walls of both ends of the sliding seat 3. The guide plates 4 adopt a triangular structure design.

[0028] In this structural design, when filamentous waste appears on the front guide rail body 1 in the forward direction of the sliding seat 3, the guide plate 4 can abut against the filamentous waste during the forward movement of the sliding seat 3. The guide plate 4, with its triangular structure, has guide ramps on both sides according to its structural characteristics. These ramps abut against and guide the contacting filamentous waste from both sides, causing it to slide and be guided to both sides as the sliding seat 3 moves forward. This effectively prevents the filamentous waste from entering between the guide rail body 1 and the sliding seat 3, avoiding entanglement and obstruction, preventing guide rail malfunctions, improving the operational stability and service life of the guide rail structure. Furthermore, the guide plate 4 has a simple structure, is easy to install, and is more convenient to use.

[0029] In this embodiment, in order to facilitate locking when the guide rail structure is stationary, threaded holes 9 are provided at the center of both sides of the sliding seat 3, and locking pins 10 are internally threaded into the two threaded holes 9.

[0030] A knob 11 is fixedly installed on the external end of the locking screw 10, and the knob 11 is provided with anti-slip serrations.

[0031] This structural design allows the locking pin 10 to be manually rotated via the knob 11. When the locking pin 10 rotates, it extends and retracts in the threaded hole 9, thereby making tight contact with the guide rail body 1 through rotation. This locks the sliding seat 3 when the sliding guide rail is stationary, improving the static effect of the structure and preventing the sliding seat 3 from sliding due to external forces. This effectively improves the initial positioning accuracy of the sliding seat 3 and has a better performance.

[0032] Working principle: In use, the sliding seat 3 can be assembled onto the guide rail body 1, as shown in the attached instruction manual. Figure 1 As shown, after assembly, the guide rail body 1 and the roller 8 of the sliding seat 3 are in rolling contact, and the spring 6 inside the roller 8 is in a compressed state, which can ensure the normal use effect of the sliding guide rail structure of this utility model.

[0033] This utility model features a roller 8 that can make rolling contact with the guide rail body 1. In actual use, the rolling contact effect of the roller 8 can effectively reduce the overall resistance when the sliding seat 3 is displaced and sliding. Compared with traditional sliding friction, the rolling friction of this utility model has the practical characteristics of low resistance and high smoothness, making it more practical.

[0034] After assembly, the sliding seat 3 of this invention has a compressed spring 6 inside. After long-term operation, the roller 8 will experience some natural wear, and the wheel body of the roller 8 will become thinner. Then, through the action of the internal compression spring 6, the roller 8 will be pushed forward by the compression and rebound of the spring 6 after wear, so that the roller 8 is always in close contact with the inner wall of the guide rail body 1, and is always in a close rolling contact state. It is not affected by wear during actual use, so it can effectively avoid wear gaps between the roller 8 and the guide rail, thereby effectively improving the overall running stability of the guide rail and avoiding the technical problems of decreased accuracy and insufficient stability caused by wear in traditional ball guide rails. This invention can effectively solve the technical problems of insufficient accuracy and stability caused by ball wear by the above-mentioned structure of spring 6 and roller 8. The structure is relatively simple, the manufacturing cost and difficulty are low, the practicality is good, the economy is good, and it is suitable for implementation.

[0035] Meanwhile, in actual use, when filamentous waste material from machine tool processing appears on the front guide rail body 1 in the forward direction of the sliding seat 3, the guide plate 4 can abut against the filamentous waste material during the forward movement of the sliding seat 3. The guide plate 4, with its triangular structure design, has guide ramps on both sides according to its structural characteristics. The guide ramps can abut against and guide the contacting filamentous waste material from both sides, allowing the filamentous waste material to slide and be guided to both sides during the forward movement of the sliding seat 3. This effectively prevents the filamentous waste material from entering between the guide rail body 1 and the sliding seat 3, avoiding entanglement and obstruction of the filamentous waste material, preventing guide rail operation failure, improving the operational stability and service life of the guide rail structure, and the guide plate 4 has a simple structure, is easy to install, and is more convenient to use.

[0036] Furthermore, the sliding guide rail structure of this utility model is equipped with a static locking structure. The locking screw 10 can be manually driven to rotate by the knob 11. When the locking screw 10 rotates, it will extend or retract in the threaded hole 9. In this way, the locking screw 10 can make tight contact with the guide rail body 1 through rotation. Thus, the locking screw 10 can lock the sliding seat 3 when the sliding guide rail is stationary, improve the static effect of the structure, and prevent the sliding seat 3 from sliding displacement due to external force. This can effectively improve the positional accuracy of the sliding seat 3 during initial operation and has a better performance.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
