Description

Technical Field

[0001] The utility model belongs to the field of belt-type linear slide modules, in particular to a heavy-load slide module suitable for high-temperature radiation environments. Background Art

[0002] The slide module is an indispensable device in linear motion. With the continuous development of mechanical technology, the types of slide modules have also become diverse. The belt slide module is one of the most frequently used slide modules. Among them, the slide module requires a position sensor to sense and determine the position of the slider. In a closed belt slide disclosed in Chinese patent CN210461573U, the position sensors are respectively arranged on the sides of the overall shell. These position sensors are exposed to the outside, resulting in too many protrusions on the overall outer surface of the slide. Not only can it not avoid damage from bumps during installation and use, but also in some use environments with a temperature of ≥95°C, and may even need to withstand high-temperature baking radiation above 650°C. In application scenarios, the position sensor is also completely and directly exposed to high-temperature radiation, which has a greater impact on its service life. Therefore, whether the slide module can be used in a high-temperature environment, in addition to using high-temperature resistant materials, it is also necessary to consider how the position sensor is set to minimize the impact of high temperature on it.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0040] As shown in the figure, the top cover 2 of the utility model is fixed on the top of the base profile 1. The specific fixing method is: at both ends of the base profile 1 in the length direction, end covers 5 are respectively provided. The lower end of the end cover 5 is fixed to the base profile 1 by bolts, and the upper end of the end cover 5 is fixed to the top cover 2 by bolts. The support is located in the middle part of the length direction, combined with Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the base profile 1 and the top cover 2 are supported and fixed by a support member 8. Specifically, the support member 8 is I-shaped, and its lower crossbeam 82 is fixed to the base profile 1 by bolts, and the upper crossbeam 81 supports the top cover 2 and is fixed by bolts.

[0041] See also Figure 5 As shown, the two ends of the upper surface of the main bottom plate 10 of the base profile 1 are respectively provided with a side baffle body 13, a second step body 12 and a first step body 11 which are protruding upward and decreasing in height from the outside to the center, and the second step body 12 and the first step body 11 are respectively provided with a side baffle body 13, a second step body 12 and a first step body 11 which are protruding upward and decreasing in height from the outside to the center, and the side baffle body 13, a second step body 12 and a ... Figure 7 As shown, a guide rail 6 is installed on each of the first step bodies 11 on both sides, and the guide rail 6 is fixed to the base profile 1 by bolts; the step formed between the second step body 12 and the first step body 11 provides a side limit for the guide rail 6, which is helpful for the installation and stability of the guide rail 6. In addition, the gap between the guide rail 6 and the side baffle body 13 constructed above the second step body 12 also provides an installation and movement gap for the corresponding side portion of the guide rail slider 61 slidably connected to the guide rail 6; the integrally formed side baffle body 13 serves as the side of the overall shell.

[0042] For further information, see Figure 5 As shown, the base profile 1 is also provided with two weight-reducing holes 14 penetrating along its length direction. Each weight-reducing hole 14 is located adjacent to the side baffle body 13 on the corresponding side and between the second step body 12 and the bottom surface of the main body bottom plate 10. A small part of the weight-reducing hole 14 may also intrude directly below the first step body 11, but it should be avoided to affect the bolt installation of the guide rail 6 and the supporting strength of the guide rail 6.

[0043] For further information, see Figure 5 As shown, the outer side surface of the side baffle body 13 is also formed with T-slots, such as the first T-slot 15 and the second T-slot 16 in the figure, which not only play a weight reduction function, but also provide a basis for adding external accessories or installing and fixing the module as a whole.

[0044] For further information, see Figure 5 As shown, a group of anti-deformation force release grooves 17 are also formed on the outer side surface of the side baffle body 13, and its function is self-explanatory and will not be further described.

[0045] The space between the upper surface of the main base plate 10 between the first step bodies 11 on both sides and the lower surface of the top cover 2 is used to accommodate the core part of the belt transmission mechanism for installation. Specifically, the driving pulley 40 and the driven pulley 44 are respectively rotatably connected to the two ends of the base profile 1, and a belt connecting component 42 is fixed to the transmission belt 41 that transmits the driving pulley 40 and the driven pulley 44 by clamping. The belt connecting component 42 is fixed to the slide block 3 by bolts, and guide rail sliders 61 slidably connected to the corresponding guide rails 6 are respectively fixed on both sides of the slide block 3; the driving motor 4 is fixedly installed outside the lower surface of the base profile 1, and the motor shaft of the driving motor 4 is coaxially driven and connected to the driving pulley 40 through a connecting piece passing through the base profile 1.

[0046] See also Figure 7 As shown, the axles of the driving pulley 40 and the driven pulley 41 are perpendicular to the base profile 1 and the top cover 2, and the belt surfaces of the transmission belts 41 on both sides between the driving pulley 40 and the driven pulley 41 are also perpendicular to the base profile 1 and the top cover 2, respectively. Therefore, the upper and lower channel openings of the inter-belt channel between the transmission belts 41 on both sides between the driving pulley 40 and the driven pulley 41 are also respectively oriented towards the base profile 1 and the top cover 2, and a heat-shielding tube 7 is respectively arranged at the position where the position sensor 9 needs to be arranged, each heat-shielding tube 7 passes through the inter-belt channel, and the top end of the heat-shielding tube 7 is embedded in the corresponding top cover opened on the top cover 2. Through hole 21, preferably, the top end surface of the heat-shielding tube 7 is flush with the upper surface of the top cover 2; the bottom end of the heat-shielding tube 7 is embedded in the plate body through hole 101 correspondingly opened on the main bottom plate 10 of the base profile 1, and each position sensor 9 is integrally installed in the bottom of the corresponding matching heat-shielding tube 7 tube hole 70. Specifically, the side wall of the position sensor 9 is connected and fixed to the vertical plate of the L-shaped connecting plate 91, and the vertical plate of the L-shaped connecting plate 91 extends into the bottom of the tube hole 70 of the heat-shielding tube 7, so that the position sensor 9 is located as a whole in the bottom of the tube hole 70 of the heat-shielding tube 7, and the horizontal plate of the L-shaped connecting plate 91 is then connected and fixed to the lower surface of the base profile 1 by bolts.

[0047] The above structure is not only convenient for the installation and disassembly of the position sensor 9, but also the position sensor 9 is entirely accommodated in the barrel hole 70 of the heat-shielding barrel 7, which at least ensures that the position sensor 9 is effectively isolated and protected in the front, rear, left and right directions, avoiding direct radiation of high temperature, which helps to improve its service life, and the sensing direction of the position sensor 9 is surrounded by the heat-shielding barrel 7, and only the barrel mouth directly reaching the top cover can pass through the slide block 3, which avoids the transmission belt 41, belt connection assembly 42 or guide rail slider 61 between the top cover 2 and the base profile 1. When the position sensor 9 is disturbed by the movement, it causes false induction. Therefore, this structure can make the position sensor 9 as far away from the top cover 2 as possible, and thus as far away from the heat source in the direction of the top cover 2 as possible. Furthermore, the barrel hole 70 of the heat-shielding barrel 7 also forms a ventilation channel, which is also helpful to use air cooling to dissipate heat and cool the position sensor.

[0048] Correspondingly, the main longitudinal beam of the I-shaped support member 8 for supporting and connecting the base profile 1 and the top cover also passes through the channel between the belts, making full use of the space of the channel between the belts and contributing to the overall volume control of the slide module.

[0049] Accordingly, combined Fig. 9 and Figure 3 As shown, in order to avoid the passage between belts, the heat-shielding cylinder 7 and the supporting member 8 during the movement of the slide block 3, the slide block 3 is formed with a T-slot 31 composed of a top cover through a slot hole 311 and a avoidance opening 312. The top cover through the slot hole 311 is used to pass through the top cover 2. There is a gap between the top cover through the slot hole 311 and the top cover 2 and they are not in direct contact. Therefore, when the slide block 3 moves, no friction noise will be generated with the top cover 2; the slot wall of the top cover through the slot hole 311 above the top cover 2 serves as an installation platform for the entire slide block 3 to connect the corresponding equipment. The avoidance opening 312, as the slot of the T-slot 31, is located below the top cover through the slot hole 311 and faces the space inside the shell. The avoidance opening 312 enables the slide block 3 to avoid the passage between belts, the heat-shielding cylinder 7 and the supporting member 8 during the movement to avoid interference.

[0050] Further, if Fig. 9 As shown, the guide rail slider 61 and the belt connecting assembly 42 are respectively connected to the top covers of the slide block 3 located on both sides of the avoidance opening 312 through the groove walls of the groove hole 311. This structural design makes full use of the space and has a more compact structure.

[0051] Further, if Figure 7 As shown, the top cover 2 is provided with a plurality of weight-reducing holes 22 extending along the length direction.

[0052] Furthermore, a buffer washer 51 is fixedly disposed on the end cover 5 for buffering the slide block 3 , and noise caused by collision can also be avoided.

[0053] Further, if Figure 4As shown, the belt passage also passes through a tensioning roller 43 for tensioning the drive belt.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
