Description

Technical Field

[0001] This utility model relates to the field of slide cylinder technology, specifically a guide rail-embedded slide cylinder. Background Technology

[0002] A slide cylinder is a pneumatic actuator that combines the linear drive capability of a cylinder with the high-precision guiding function of a slide. Its core structure directly drives the slide to make stable, low-friction linear displacement along a precision guide rail through the reciprocating motion of the cylinder piston. It combines the fast response characteristics of a pneumatic system with the high positioning accuracy of a mechanical guide rail. It is widely used in automated assembly, electronic manufacturing, precision testing and other scenarios that require high rigidity and high repeatability of linear motion. It is a key modular component connecting pneumatic control and mechanical action.

[0003] In the fields of automated production and precision machining, the performance stability of the slide cylinder, as a core linear motion actuator, directly affects the overall efficiency of the equipment and the quality of the product. However, during the high-speed reciprocating motion of the traditional slide cylinder, the key contact parts will generate a lot of heat due to continuous friction, which will cause the local temperature to rise sharply. This can easily lead to problems such as grease carbonization failure and thermal expansion deformation of metal parts, resulting in motion jamming, decreased positioning accuracy, or even equipment shutdown. To address this, we propose a guide rail-embedded slide cylinder. Utility Model Content

[0004] One of the technical problems to be solved in this application is: to solve the problem of motion jamming and decreased accuracy caused by a sharp increase in temperature when the slide cylinder is in long-term high-speed reciprocating motion.

The two rows of spherical grooves are respectively provided on the upper and lower sides of the triangular protrusion, and sliding balls are movably connected inside the spherical grooves.

[0008] Preferably, one side surface of the slider is provided with an arc-shaped notch, and two arc-shaped notches are provided and symmetrically distributed. The inner side of the arc-shaped notch is adapted to the sliding ball, and the outer side of the sliding ball is in contact with the inner wall of the arc-shaped notch.

[0022] 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.

[0023] Example

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7This utility model provides a technical solution: a guide rail inlaid slide cylinder, including a cylinder 1, a cylinder rod 2 fixedly connected to the output end of the cylinder 1, a connecting plate 3 fixedly connected to one end of the cylinder rod 2, a slide 4 fixedly connected to one side surface of the connecting plate 3, the slide 4 being disposed on one side surface of the cylinder 1, a guide rail 5 fixedly connected to one side surface of the cylinder 1, a certain space gap existing between one side surface of the guide rail 5 and one side surface of the slide 4, the two not contacting each other, effectively reducing frictional resistance during movement, a slider 6 fixedly connected to one side surface of the slide 4, two sliders 6 being provided and symmetrically and evenly distributed, the two sliders 6 being respectively disposed on the left and right sides of the guide rail 5, triangular protrusions 7 fixedly connected to both sides of the guide rail 5, and an inner groove 8 being formed on one side surface of the slider 6.

[0025] The inner groove 8 has sliding inclined surfaces 9 on both sides. The side ends of the triangular protrusion 7 are respectively attached to the two sliding inclined surfaces 9. The protruding end of the triangular protrusion 7 is located inside the inner groove 8. The inner groove 8 has a cavity with a certain space. By moving as a whole, and with a small gap in the space, the airflow velocity inside is high during the movement, which achieves the heat dissipation and cooling effect on the side ends of the triangular protrusion 7 and the sliding inclined surfaces 9.

[0026] Both sides of the guide rail 5 are provided with spherical grooves 10, and two rows of spherical grooves 10 are provided on one side of the guide rail 5. The two rows of spherical grooves 10 are respectively located on the upper and lower sides of the triangular protrusion 7. Sliding balls 11 are movably connected inside the spherical grooves 10. The sliding balls 11 are snapped into the inside of the spherical grooves 10 and can move inside the spherical grooves 10.

[0027] One side surface of the slider 6 is provided with an arc-shaped notch 12. There are two arc-shaped notches 12, which are symmetrically distributed. The inner side of the arc-shaped notch 12 is adapted to the sliding ball 11, and the outer side of the sliding ball 11 is in contact with the inner wall of the arc-shaped notch 12. When the sliding ball 11 contacts the arc-shaped notch 12, the cylinder 1 drives the slide table 4 and related components to move. The sliding ball 11 uses its own rolling inside the spherical groove 10 to facilitate the guiding movement of the slider 6.

[0028] Two air ducts 13 are provided on the inner side of the slider 6, and the two air ducts 13 pass through one end of the slider 6. A first arc panel 14 is provided on the inner side of the air duct 13, and a second arc panel 15 is provided on one side of the first arc panel 14. Both ends of the first arc panel 14 and the second arc panel 15 are fixedly connected to the inner wall of the air duct 13. One end of the first arc panel 14 and the second arc panel 15 is fixedly connected to the position opposite to the sliding inclined surface 9 and the arc-shaped recess 12 to facilitate the heat conduction effect at this position. One side of the inner side of the air duct 13 is arc-shaped, and the first arc panel 14 and the second arc panel 15 are arc-shaped as a whole. The thickness of the center of the first arc panel 14 and the second arc panel 15 is greater than that of the two arc panels 15. The air duct 13 is thinner at both ends, and the openings at both ends are larger than the opening at the center. The curvature of the first arc panel 14 and the second arc panel 15 is adapted to one side of the air duct 13, presenting a gradual change overall. The first arc panel 14 and the second arc panel 15 are used to separate the interior of the air duct 13. The internal conduction space is designed in an arc shape, and the space at both ends is larger than that at the center. When the cylinder 1 drives the slide table 4 and the two sliders 6 to move back and forth, the airflow is circulated back and forth inside the air duct 13. Since the heat dissipation efficiency at the center is lower than that at both ends, the overall arc-shaped guiding design makes the airflow at the center more rapid than that at both ends, which can achieve a more effective air cooling effect at the center.

[0029] Through-hole slots 16 are provided on both sides of the guide rail 5, and a vent 17 is provided on one side of the connecting plate 3. The opening direction of the two through-hole slots 16 is directly opposite the vent 17. The connection between the two through-hole slots 16 and the vent 17 facilitates the air circulation inside the through-hole slots 16, thereby achieving the cooling effect of the triangular protrusion 7 and the sliding ball 11 on the side of the guide rail 5. When the two sides of the triangular protrusion 7 are in contact with the sliding inclined surface 9 and when the sliding ball 11 is in contact with the arc-shaped recess 12, the heat generated is guided backward to one side of the through-hole slot 16, and the cooling effect is achieved through the air circulation. One end of the cylinder rod 2 is fixedly connected to an I-shaped clamp 18. A connecting groove 19 is provided on one side surface of the connecting plate 3. The I-shaped clamp 18 is fixedly snapped into the inside of the connecting groove 19. When the cylinder 1 drives the cylinder rod 2 to reciprocate, the connection between the I-shaped clamp 18 and the connecting groove 19 facilitates the synchronous movement of the connecting plate 3 and the slide table 4.

[0030] One side surface of cylinder 1 has an air inlet / outlet port 20. There are two air inlets / outlets 20, which are respectively located at both ends of one side of cylinder 1. The two air inlets / outlets 20 are connected to air pipes. The air inlet and outlet are controlled by a solenoid valve to drive the piston. Cylinder 1 uses compressed air as power to drive cylinder rod 2 to perform linear reciprocating motion. One end of cylinder 1 is fixedly connected to a buffer pile 21. The buffer pile 21 is used to buffer the cylinder 1 when it runs to a designated position during use. One side of cylinder 1 has an auxiliary guide groove 22. There are two auxiliary guide grooves 22. The two auxiliary guide grooves 22 are symmetrically distributed vertically and are used to engage with external guiding devices, thereby facilitating a more stable auxiliary guiding function for the overall use.

[0031] When the entire device is in use, its cylinder 1 is powered by compressed air and connected to an air pipe through two air inlets and outlets 20. A solenoid valve controls the airflow to drive the piston, which in turn causes the cylinder rod 2 to reciprocate linearly. Simultaneously, the I-shaped clamp 18 and the connecting groove 19 work together to move the connecting plate 3 and the slide 4 synchronously. As the slide 4 moves, the slider 6, fixed at one end, engages with the triangular protrusions 7 on both sides of the guide rail 5 via the sliding inclined surfaces 9 on both sides of the inner groove 8. At the same time, the sliding ball 11 in the spherical groove 10 on the side of the guide rail 5 engages with the arc-shaped recess 12 of the slider 6. The sliding ball 11 rolls within the spherical groove 10, facilitating the guiding movement of the slider 6. During the overall movement, the air duct 13 adopts a gradually changing arc structure, in conjunction with the first arc panel 14 and the second arc surface... The guiding effect of plate 15 increases the airflow velocity in the middle of the inner side of the air passage 13 compared to the two ends, forming a targeted air-cooling channel and enhancing the heat dissipation effect on high-load areas. At the same time, the small cavity formed by the inner groove 8 of slider 6 and the triangular protrusion 7 of guide rail 5 accelerates the internal airflow circulation during high-speed movement, effectively removing the heat generated by the friction of sliding inclined surface 9. Overall, it ensures the continuous cooling of triangular protrusion 7 and sliding ball 11, significantly slows down the aging rate of grease, effectively extends the service life of key components such as guide rail 5 and slider 6, and provides a reliable guarantee for long-term stable operation. In addition, the buffer pile 21 at one end of cylinder 1 plays a buffering role when it runs to the designated position, and the auxiliary guide groove 22 on one side can be engaged with the external guide device to achieve auxiliary guidance, making the overall operation more stable and improving the overall practicality.
