Technical Field

[0001] This utility model relates to the field of linear transmission, and in particular to a linear slide table. Background Technology

[0002] Currently, linear drive technology is being used more and more widely, especially linear slides, which are widely used in various industrial equipment or industrial production due to their economy and durability.

[0003] In some linear slides on the market, the slide and base slide using ball bearings. This effectively reduces friction during sliding. However, during rolling, the balls are prone to colliding with each other or with the guide rail, which can affect the lifespan of the slide and generate significant noise, resulting in a poor user experience.

[0004] In addition, in existing slides, the ball chain often requires a large space, resulting in a smaller width of the slide block, which in turn affects the effective load of the slide and makes it unsuitable for some high-load application scenarios.

[0005] In view of this, it is indeed necessary to provide a smooth and quiet linear slide to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a silent and smoothly operating linear slide.

The slide block has a main body and an upper end located above the main body. The main body includes an outer surface facing the outer guide rail, the outer surface forming an outer channel with the outer guide rail. Along the length direction of the slide block, the slide block has two parallel inner channels, one of which, along with the circulation device and the outer channel, forms a circulation path on one side. The sliding chain slides along the circulation path. The sliding chain includes a chain belt and balls embedded in the chain belt. The chain belt includes several equally spaced mounting holes, and the balls are mounted on the mounting holes.

[0008] As a further improvement of this utility model, the outer guide rail is provided with an outer groove on the side facing the outer side, and an inner guide rail corresponding to the outer guide rail is also provided on the outer side. The inner guide rail is provided with an inner groove on the side facing the outer guide rail, and the outer groove and the inner groove form the outer channel through which the slip chain passes.

[0009] As a further improvement of this utility model, the circulation device includes an outer circulation device and an inner circulation device. The inner circulation device is located between the outer circulation device and the slide block. The outer circulation device and the inner circulation device cooperate to form a bend. The sliding chain changes its sliding direction after passing through the circulation device.

[0010] As a further improvement of this utility model, a sleeve is embedded in the inner channel, and a guide groove is provided in the sleeve. The guide groove is symmetrically arranged on both sides of the axis of the inner channel, and guide bars are symmetrically provided on the slip chain. The guide bars are inserted into the guide groove.

[0011] As a further improvement of this utility model, the slide block is provided with a mounting groove on the side facing the bottom surface. The sliding module also includes a moving part and a stator. The moving part is installed in the mounting groove, and the stator is installed on the bottom surface. The moving part drives the sliding module to move along the path of the stator.

[0012] As a further improvement of this utility model, the linear slide also includes a distance measuring device, which includes a reading head and a scale. The scale is disposed on one side of the sidewall facing away from the rolling assembly. The reading head is fixedly connected to the side of the slide near the scale. The reading head is configured to read the scale on the scale.

[0013] As a further improvement of this utility model, the sliding module also includes a dustproof plate, which is located on the side of the slide away from the bottom surface. Anti-collision blocks are also provided at both ends of the slide, and dustproof filter screens are provided at both ends of the base along its length.

[0014] As a further improvement of this utility model, the upper end includes a support platform and connecting portions located on both sides of the support platform. The support platform protrudes in a direction away from the main body. The slide also includes a dustproof plate that covers the support platform. The linear slide also includes a steel strip that passes between the dustproof plate and the support platform.

[0017] This invention provides a linear slide table where the slide block slides relative to a base via a sliding chain. The chain separates the ball bearings, ensuring they do not collide during operation, effectively reducing noise and improving the smoothness of the slide block's movement. Simultaneously, due to the chain's limiting effect, ball bearing misalignment is minimized, preventing collisions with the base and slide block, thus extending the service life of the linear slide table. Furthermore, the internal channel within the slide block allows for the embedding of the sliding chain, enabling the installation of wider and thicker chains. The thicker spacers in the chain provide stronger structural support, making the chain less prone to deformation under tensile and compressive loads, thereby improving the overall strength and rigidity of the chain and resulting in better noise reduction. This meets the requirements for long-distance sliding of the slide block, ensuring the chain maintains a stable and reliable operating state during long-term use. Attached Figure Description

Detailed Implementation

[0027] The following detailed description of the features and advantages of this utility model is sufficient to enable those skilled in the art to understand the technical content of this utility model and implement it accordingly. Furthermore, based on this specification, claims, and drawings, those skilled in the art can easily understand the related objectives and advantages of this utility model.

[0028] Please see Figures 1-6As shown, a linear slide table 100 of this utility model includes a base 110 and a sliding module. The sliding module is slidably connected to the base 110, allowing the base 110 to slide. Specifically, the sliding module includes a slide 120 and rolling components 180 symmetrically arranged on both sides of the centerline along the length of the slide 120. The rolling components 180 include a circulation device 181 and a sliding chain 182. Circulation devices 181 are installed at both ends of the slide 120 along its length. The base 110 includes a bottom surface 111 and side walls 112 located on both sides of the bottom surface 111 and perpendicular to the bottom surface 111. An outer guide rail 171 is provided on the side wall 112. The main body of the slide 120... 21 and the upper end portion 122 located above the main body 121. The main body 121 includes an outer side facing the outer guide rail 171. The outer side and the outer guide rail 171 form an outer channel 123. Along the length direction of the slide 120, the slide 120 is provided with two parallel inner channels 124. One inner channel 124, the circulation device 181 and the outer channel 123 form a circulation path on one side. The circulation path is a closed ring. When the slide 120 slides relative to the base 110, the slide chain 182 slides along the circulation path. The slide chain 182 includes a chain belt 1821 and balls embedded in the chain belt 1821. The chain belt 1821 includes a plurality of equally spaced mounting holes 1823. The balls are mounted on the mounting holes 1823.

[0029] In the linear slide 100, the rolling components 180 are symmetrically arranged on both sides of the centerline of the slide 120 along its length, making the force on the slide 120 more uniform during sliding. This effectively reduces skewness and errors caused by uneven force, thereby improving the straightness and positioning accuracy of the slide 120. The inner channel 124, the circulation device 181, and the outer channel 123 form a closed annular circulation path, in which the balls can smoothly circulate and roll, avoiding jamming or irregular movement of the balls during movement, thus improving the smoothness and repeatability of the linear slide 100. The rolling of the balls in the rolling components 180 replaces the traditional sliding friction with rolling friction, greatly reducing the frictional resistance between the slide 120 and the base 110, allowing the slide 120 to slide more easily and move more smoothly. This effectively avoids low-speed crawling and improves the stability of the movement. At the same time, because rolling friction is used instead of sliding friction, the friction between the balls and the guide rail is significantly reduced, thereby reducing noise generated by friction. The rolling friction characteristic results in low noise levels during the operation of the linear slide, typically within a low decibel range. The chain 1821 fixes the balls at equal intervals, and the spacers 1822 within the chain 1821 ensure that the balls do not collide or misalign during movement, guaranteeing the orderly movement of the balls and further improving the stability and reliability of the linear slide. The chain 1821 prevents direct collisions between the balls, resulting in excellent quiet operation when the slide 120 slides relative to the base 110. Simultaneously, the limiting effect of the chain 1821 minimizes ball misalignment, preventing collisions between the base 110 and the slide 120, effectively extending the service life of the linear slide 100. Furthermore, the rationally designed circulation path of the chain 1822 and the equidistant distribution of the mounting holes 1823 in the chain 1821 ensure uniform force distribution on the balls, making the slide 120 run more smoothly and meeting the requirements of high-precision equipment.

[0030] Meanwhile, the internal channel 124 in the slide block 120 enables partial embedding of the slip chain 182, allowing a wider and thicker slip chain 1821 to be installed in the slide block 120. The wider and thicker slip chain 1821 provides stronger structural support, making it less prone to deformation when subjected to tensile, compressive, and other loads, thereby improving the overall strength and rigidity of the slip chain 1821 and also resulting in better noise reduction. This meets the requirements of long-distance sliding of the slide block 120 and ensures that the slip chain 1821 maintains a stable and reliable operating state during long-term use.

[0031] Furthermore, an outer groove is provided on the outer side of the outer guide rail 171 facing outwards, and an inner guide rail 172 corresponding to the outer guide rail 171 is also provided on the outer side of the outer guide rail 172. An inner groove is provided on the side of the inner guide rail 172 facing the outer guide rail 171. The outer groove and the inner groove form an outer channel 123 for the slip chain 182 to pass through. The inner guide rail 172 and the outer guide rail 171 together form the outer channel 123. In this way, the slip chain 182 passes through the outer channel 123, avoiding direct contact between the slip chain 182 and the slide block 120 and the base 110. In some applications, such as video processing lines, the slip chain 182 is wrapped in the outer channel 123, which makes it less likely to accumulate oil and impurities, and facilitates cleaning and maintenance. In some embodiments, both the inner guide rail 172 and the outer guide rail 171 are made of damping or rubber and other sound-silencing materials.

[0032] In this embodiment, the circulation device 181 includes an outer circulator 1811 and an inner circulator 1812. The inner circulator 1812 is located between the outer circulator 1811 and the slide block 120. The assembly of the inner circulator 1812 and the outer circulator 1811 forms a bend 1813 for the slip chain 182 to turn, thereby changing the sliding direction of the slip chain 182. This allows the slip chain 182 to circulate and slide within the inner channel 124, the circulation device 181, and the outer channel 123, achieving smooth sliding of the slide block 120 relative to the base 110. Through a reasonable circulation design, the balls are subjected to uniform force during circulation, reducing the possibility of excessive local wear, thereby extending the service life of the slip chain 182, the slide block 120, and the base 110, and reducing equipment maintenance costs.

[0033] In this embodiment, the inner channel 124 is provided with a guide groove 1251, which is symmetrically arranged on both sides of the axis of the inner channel 124. The slide chain 182 is provided with a guide bar, which is inserted into the guide groove 1251. In this way, the slide chain 182 will not deviate or shake when sliding in the loop path, and the sliding process is more stable.

[0034] In this embodiment, the chain belt 1821 includes a plurality of spacer strips 1822, and two adjacent spacer strips 1822 form the mounting hole 1823. Along the length direction of the chain belt 1821, the thickness of the spacer strip 1822 is a first length, and the width of the mounting hole 1823 is a second length. The ratio of the first length to the second length is greater than or equal to 0.65. When the ratio of the thickness of the spacer strip 1822 to the width of the mounting hole 1823 reaches 0.65, the thickness of the spacer strip 1822 is relatively large, which can provide stronger structural support for the chain belt 1821, making it less prone to deformation when subjected to tensile, compressive, and other loads. This improves the overall strength and rigidity of the chain belt 1821, and also brings better noise reduction, ensuring that the chain belt 1821 maintains a stable and reliable operating state during long-term use. Meanwhile, the appropriate ratio of the thickness of the spacer band 1822 to the width of the mounting hole 1823 helps to disperse the stress generated by the chain belt 1821 under load, preventing excessive stress concentration around the mounting hole 1823. This reduces the risk of fatigue cracks in the chain belt 1821 due to stress concentration and extends its service life. By optimizing the structural design of the chain belt 1821, its strength, stability, and wear resistance are improved, thereby enhancing the overall performance and reliability of the slide table. This allows it to meet the requirements of higher precision, longer lifespan, and more stable operation, ensuring efficient operation of the equipment.

[0035] Furthermore, a sleeve 125 is provided in the inner channel 124. In this embodiment, the sleeve 125 is made of damping material such as nylon or rubber, which can avoid direct rigid contact between the slip chain 182 and the inner channel 124, and also has better sound absorption and vibration absorption effect, and can achieve better quiet operation.

[0036] In this embodiment, the slide 120 has a mounting groove on the side facing the bottom surface 111. The sliding module also includes a mover device 161 and a stator device 162. The mover device 161 is installed in the mounting groove, and the stator device 162 is installed on the bottom surface 111. The mover device 161 drives the sliding module to move along the path of the stator device 162. The cooperation of the mover device 161 and the stator device 162 enables precise control of the movement of the slide 120, ensuring that the slide 120 moves along a predetermined path and speed, thereby improving the automation and precision level of the equipment. Installing the mover device 161 in the mounting groove of the slide 120 and installing the stator device 162 on the bottom surface 111 of the base 110 makes the entire linear slide 100 more compact, saves space, and facilitates installation and use in limited spaces.

[0037] The sliding module also includes a dustproof plate 126, which is located on the side of the slide block 120 away from the bottom surface 111. The dustproof plate 126 can prevent dust and debris from entering the interior of the slide block 120, avoid frequent maintenance of the slide block 120, and extend the service life of the slide block 120.

[0038] Along the length of the slide 120, anti-collision blocks are provided at both ends of the slide 120. This ensures that the slide 120 will not rigidly collide with the two ends of the base 110 along its length when the slide 120 is running. The anti-collision blocks can effectively absorb the impact force of the slide 120, further improving the safety of the linear slide 100 during operation.

[0039] In this embodiment, the linear slide 100 further includes a ranging device 150, which includes a reading head 151 and a scale 152. The scale 152 is disposed on the side wall 112 of one side facing away from the rolling assembly 180. The reading head 151 is fixedly connected to the slide 120 and is configured to read the scale on the scale 152. When the slide 120 slides, the reading head 151 slides with the slide 120. The reading head 151 reads the scale on the scale 152 in real time to record and feed back the real-time position of the slide 120 to the control system of the linear slide 100, so as to achieve precise control of the specific sliding position of the slide 120 and improve the accuracy of the linear slide 100.

[0040] Furthermore, the upper end 122 includes a support platform 1221 and connecting portions 1222 located on both sides of the support platform 1221. The support platform 1221 protrudes in a direction away from the main body 121. The slide also includes a dustproof plate 126, which covers the support platform 1221. The linear slide 100 also includes a steel belt 102, which is fixedly connected to both ends of the slide 120. The steel belt 102 passes through the dustproof plate 126 and the support platform 1221. The steel belt 102 and the dustproof plate 126 can effectively prevent external dust or dirt from entering the interior of the base 110 and can effectively protect the various components inside the base 110 from contamination or impact.

[0041] The linear slide 100 also includes a limiting module 140, which includes a limiting photoelectric sensor 142 and a photoelectric sensor 141. The photoelectric sensor 141 is fixedly connected to the side of the upper end 122 away from the reading head 151. The limiting photoelectric sensor 142 is mounted on the side wall 112 of the slide 120 without the grid ruler 152. Along the length of the base 110, the limiting photoelectric sensor 142 is located at both ends of the base 110. When the photoelectric sensor 141 slides into the limiting photoelectric sensor 142...

[0042] The slide 120 will stop sliding, which can ensure the safety of the linear slide 100 during operation and prevent the slide 120 from overshooting.

[0043] Furthermore, dust filter covers 101 are provided at both ends of the base 110 along its length. The dust filter covers 101 can ensure that the linear slide 100 has good heat dissipation and prevent external debris and dust from entering the base 110, thus preventing contamination of the internal structural components and reducing the frequency of cleaning.

[0044] In summary, the linear slide table 100 of this utility model has a slide block 120 that slides relative to the base 110 via a sliding chain 182. The chain 1821 in the sliding chain 182 separates the balls, ensuring that the balls do not collide with each other during operation, effectively reducing noise and improving the smoothness of the slide block 120's movement. Simultaneously, due to the limiting effect of the chain 1821, the ball offset is also small, preventing collisions between the base 110 and the slide block 120, effectively extending the service life of the linear slide table 100. Furthermore, the slide block 120 is equipped with... The inner channel 124 is designed to embed the sliding chain 182, allowing the sliding block 120 to install a wider and thicker sliding chain 1821. The thicker spacer 1822 in the middle of the sliding chain 1821 provides stronger structural support for the sliding chain 1821, making it less prone to deformation when subjected to tensile, compressive, and other loads. This improves the overall strength and rigidity of the sliding chain 1821, and also brings better noise reduction. It can meet the requirements of long-distance sliding of the sliding block 120 and ensure that the sliding chain 1821 maintains a stable and reliable operating state during long-term use.
