Description

End seal and linear guide system
Technical Field
The invention relates to an end seal and a linear guide system comprising the end seal.
Background
The linear guide system capable of bearing forces and moments in multiple directions can be widely applied to the fields of machine tools, industrial automation and the like. Generally, a linear guide system includes a guide rail and a slider. The slider is established on the guide rail and can follow the guide rail slip. The linear guide system further comprises an end seal. The end seal is provided at an end of the slider and seals a gap between the guide rail and the slider by a seal lip. In most applications, the linear guide system requires a contact seal to prevent contamination of the linear guide system with cutting chips and cutting fluid. In the linear guide system, a guide rail having a countersunk mounting hole at an upper portion is one of the most applied types. In order to avoid the cutting chips from being hidden in the counter bore and the upper sealing lip from being damaged by the edge of the counter bore, a filling piece which is in interference fit with the guide rail is designed. After the guide rail is fixed with the screws, the caulking pieces are fitted into the countersunk holes in the guide rail, so that the upper surface of the guide rail is completely filled with a surface having no gap.
However, in the packaging of the assembled product without adhesive tape on the rails and in customer acceptance tests, failure of the upper sealing lip in the sealing device was found. By analyzing the failure mode of the upper sealing lip, the sharp edge of the countersunk mounting hole on the guide rail is the main reason. Although such a risk of failure has been taken into account at the time of design and it is clearly warned in the product catalogue that the assembly of the rail and the slider would damage the sealing device without loading the plug blades, in practical applications customers complain that the adhesive tape on the complaint rail is difficult to remove and that the adhesive tape on the upper surface of the rail must be removed in acceptance tests. In both cases described above, no shim is fitted. This is because the installation of the shim is disposable and therefore the shim is not assembled to the guide rail before the linear guide system is installed as it is.
The reason for not chamfering the sharp edge of the guide rail counterbore is that there will be a gap between the chamfered shim and the chamfered edge. The gap may damage the upper seal lip, and cutting chips hidden in the gap may contaminate the slider, thereby causing the entire slider to fail.
There are two technical solutions to solve the failure of the upper sealing lip in the prior art. One solution is to develop a new type of adhesive tape for use on the guide rails. However, this approach only addresses the problem of failure of the sealing lip during packaging. Another solution is to mount the protective metal sheet between the counter-sunk hole of the guide rail and the upper sealing lip during the acceptance test. However, the protective metal sheet of a steel material risks scratching the surface of the guide rail and scratching the fingers of workers, while the protective metal sheet of a copper or aluminum material is expensive because it is discarded after formal installation of the caulking pieces.
Accordingly, it is desirable to provide an end seal that prevents seal failure for a linear guide system.

Detailed Description
Hereinafter, exemplary embodiments of the present invention are described with reference to the accompanying drawings. It should be understood that the detailed description is only intended to teach one skilled in the art how to practice the invention, and is not intended to limit the scope of the invention.
The terms "upper", "lower", "left", "right", "front", "rear" are used herein. These terms are each defined with reference to the orientation shown in the drawings and are intended to facilitate describing the relative position of a particular part or assembly with respect to other parts or assemblies, rather than the absolute position with respect to a geodetic coordinate system. It will be understood that when a component or assembly is shown in a drawing rotated by a predetermined angle relative to its position, other components or assemblies will correspondingly rotate by the predetermined angle and deviate from the position shown.
Fig. 1 is a side view of a linear guide system in which a lower surface of an upper seal member is spaced a predetermined distance from an upper surface of a guide rail according to an embodiment of the present invention, and fig. 2 is a side view of a linear guide system in which a lower surface of an upper seal member conforms to an upper surface of a guide rail according to an embodiment of the present invention. As shown in fig. 1 and 2, the linear guide system 1 includes a guide rail 11 and a slider 12. The slide block 12 is sleeved on the guide rail 11 and can slide along the guide rail 11. The upper surface 110 of the guide rail 11 has a counterbore (not shown), and a screw (not shown) can pass through the counterbore to mount the guide rail 11 at a fixed position. The linear guide system 1 further comprises an end seal 13.
Fig. 3 is an exploded perspective view of an end seal according to an embodiment of the present invention, fig. 4 is an assembled perspective view of an end seal according to an embodiment of the present invention, fig. 5 is a side view of a portion of an end seal according to an embodiment of the present invention, and fig. 6 is a side view of a portion of an end seal according to an embodiment of the present invention. As shown in fig. 3 to 6, the end sealing device 13 is installed at an end of the slider 12 and includes a base member 130 and a sealing assembly 131. The base member 130 is longitudinally formed with a channel 1301. Fig. 4 to 6 show an XYZ coordinate system, and the longitudinal direction refers to the Z-axis direction. The seal assembly 131 includes an upper seal 1311, a left side seal 1312, and a right side seal 1313. The upper seal 1311 and the pair of side seals 1312, 1313 are mounted to the base member 130 at the end surface in the longitudinal direction and enclose an opening 1314. The opening 1314 communicates with the passage 1301 of the base member 130, and the guide 11 can pass through the passage 1301 and the opening 1314. Sealing lips surrounding the opening 1314 are formed at the lower end edge 1311a of the upper seal 1311, the right end edge 1312a of the left side seal 1312, and the left end edge 1313a of the right side seal 1313, respectively.
As shown in fig. 1, the sealing lips of the left and right side seals 1312, 1313 respectively abut the left and right side surfaces 112 of the rail 11, while the sealing lip of the upper seal 1311 is spaced apart from the upper surface 110 of the rail 11 by a predetermined distance L. The predetermined distance L may be sized such that the sharp edge of the counterbore does not damage the sealing lip of the upper seal 1311. In the state shown in fig. 1, the end seal 13 fails to seal the linear guide system 1. For convenience of description, the position where the upper seal 1311 in fig. 1 is located is referred to herein as the non-sealing position.
As shown in fig. 2, the upper seal 1311 and the left and right side seals 1312, 1313 are respectively fitted to the upper surface 110, the left side surface 111, and the right side surface 112 of the rail 11. In the state shown in fig. 2, the end seal 13 can seal the linear guide system 1. Herein, for convenience of description, the position where the upper seal member is located in fig. 2 is referred to as a sealing position.
During a packaging process or acceptance test of the linear guide system, the upper seal 1311 is in the non-sealing position shown in fig. 1. In the non-sealing position, the sealing lip of the upper seal 1311 is spaced a predetermined distance from the upper surface 110 of the rail 11. Thereby, the sealing lip is not damaged by the sharp edge of the counter bore on the guide rail 11. After the linear guide system 1 is fully installed (at this time, the shim is installed into the counterbore), the upper seal 1311 is pushed down so that the upper seal 1311 moves down to the sealing position shown in fig. 2. In the sealing position, the sealing lip of the upper seal 1311 abuts the upper surface 110 of the rail 11. Thereby, the linear guide system is sealed, so that leakage of lubricant is reliably avoided and contamination of the linear guide system by contaminants such as dust, cutting chips, cutting fluid and the like is prevented.
It can be seen that the end seal according to embodiments of the present invention can prevent the seal lip from being damaged by the sharp edge of the counterbore, thereby preventing the end seal from failing in sealing the linear guide system. Second, the end seals do not require adhesive tape to be applied during packaging and do not require tape to be torn off during normal installation, thereby reducing cost and improving production efficiency. Furthermore, there is no need to install a disposable metal protection sheet in the countersink, thereby avoiding the risk of scratching the surface of the guide rail and scratching the fingers of the worker and reducing costs.
According to an embodiment of the invention, the end seal is configured such that the upper seal cannot move upwards at the sealing position. This prevents the upper seal 1311 from failing to conform to the upper surface 110 of the rail 11, thereby preventing the inability to seal the linear guide system 1.
As shown in fig. 3 and 4, the end seal 13 further includes a scraping piece 132. The scraping piece 132 is provided at an end face of the seal assembly 131 in the longitudinal direction, and the seal assembly 131 is sandwiched between the scraping piece 132 and the base member 130. The scraping blade 132 may be secured to the base member 130 by a screw 133. The scraping piece 132 is opened with a passage 1321 in the longitudinal direction, and the guide rail 11 can pass through the passage 1321. The inner surface of the channel 1321 generally conforms to the corresponding outer surface of the rail 11 for rough cleaning of the rail 11 of contaminants. The scraping blade 132 may be made of a metallic material.
Fig. 5 and 6 together with fig. 1 and 2 clearly show the internal structure of the end seal 13. As shown, the upper seal 1311 is provided with a first engagement unit 1315, and the first engagement unit 1315 includes an upper catch 1315a and a lower catch 1315 b. The base member 130 is provided with a second engagement unit 1316, and the second engagement unit 1316 includes an upper card slot 1316a and a lower card slot 1316 b. When the upper seal 1311 is in the unsealed position, the upper catch 1315a engages the upper catch 1316 a. When the upper seal 1311 is pushed downward, the upper catch 1315a disengages from the upper catch 1316a and the upper seal 1311 moves downward into a sealing position. In the sealed position, lower catch 1315b engages lower catch 1316 b.
The above describes a specific embodiment in which the first coupling unit 1315 is configured in a snap form and the second coupling unit 1316 is configured in a card slot form. It should be understood that the first engaging unit and the second engaging unit may be other engaging forms than the snap connection known in the art as long as the engaging relationship between the first engaging unit and the second engaging unit ensures that the upper seal member can be in the non-sealing position and the sealing position and can be moved downward from the non-sealing position to the sealing position. For example, the first engaging unit and the second engaging unit may be engaged by bonding, magnetic connection, or the like.
The above describes a specific embodiment in which the first engagement unit 1315 includes two first engagement portions (i.e., an upper snap and a lower snap) and the second engagement unit 1316 includes two second engagement portions (i.e., an upper card slot and a lower card slot). It should be understood that the number of the first engaging portions and the second engaging portions is not limited thereto. For example, the number of the first engaging portions and the second engaging portions may be one or more. In the non-sealing position, the at least one first engagement portion engages with the at least one second engagement portion, and in the sealing position, the one or more first engagement portions engage with the one or more second engagement portions. In one example, the one or more first engaging parts engaged at the sealing position may be the remaining first engaging parts of all the first engaging parts except for the at least one first engaging part engaged at the non-sealing position. In one example, the at least one first engagement portion engaged at the non-sealing position may coincide with the one or more first engagement portions engaged at the sealing position. In another example, in the case where the number of the first engaging portions is one, the first engaging portions engaged at the sealing position are the same as the first engaging portions engaged at the non-sealing position. Similarly, the distribution pattern of the second engaging portions engaged at the sealing position and the non-sealing position is similar to that of the first engaging portion, and therefore, the description thereof is omitted.
It should be understood that the form of the first engaging unit and the second engaging unit may be interchanged. For example, the first engagement unit may be in the form of a snap groove, and the second engagement unit may be in the form of a snap.
Upper catch 1315a includes hooked upper catch 1315a1, and lower catch 1315b includes hooked lower catch 1315b 1. The upper and lower hooks 1315a, 1315b are engaged with the upper and lower card slots 1316a, 1316b by the hook-shaped upper and lower engaging portions 1315a1, 1315b 1. It should be understood that the upper and lower engaging portions may have other shapes known in the art.
Upper and lower catches 1315a, 1315b are integrally formed and communicate with corresponding upper and lower catch slots 1316a, 1316 b. As shown in fig. 5, upper catch 1315a and lower catch 1315b (i.e., first engagement unit 1315) are integrally formed in a substantially T-shape, and both ends of a lateral portion of the T-shape are hook-shaped. It should be understood that upper catch 1315a and lower catch 1315b may also be formed separately.
The first coupling unit 1315 and the upper seal 1311 are integrally formed. The first coupling unit 1315 and the upper seal 1311 are, for example, rubber or plastic material. The first coupling unit 1315 and the upper seal 1311 have flexibility, and thus the shape of the first coupling unit 1315 is changed as the upper seal 1311 moves downward from the non-sealing position to the sealing position. As shown in fig. 1 and 2, the first coupling unit 1315 is inclined from left to right.
The above describes a specific embodiment in which upper catch 1315a and lower catch 1315b include a hook-like structure and are integrally formed in a T-shape. However, upper and lower snaps 1315a, 1315b may be designed in other shapes known in the art, so long as the configuration of upper and lower snaps 1315a, 1315b ensures that upper seal 1311 can be in both the unsealed and sealed positions and can be moved downward from the unsealed position to the sealed position.
According to an embodiment of the present invention, upper catch 1315a disengages from upper catch 1316a when upper seal 1311 is pushed downward in the unsealed position, and upper seal 1311 cannot move upward when in the sealed position. This can be achieved by designing the shape of upper and lower catches 1315a, 1315 b. Fig. 7 shows the upper engaging portion 1315a1 and the lower engaging portion 1315b1 in an enlarged view. For example, as shown in fig. 7, the hook angle α of the upper engaging portion 1315a1 is relatively large, and the hook angle β of the lower engaging portion 1315b1 is relatively small. In addition, this objective may also be accomplished by shaping upper card slot 1316a and lower card slot 1316 b.
According to an embodiment of the present invention, the upper seal 1311 is provided with two first coupling units 1315, and the two first coupling units 1315 are provided at both left and right sides of the upper seal 1311. The base member 130 is provided with two second engagement units 1316, and the two first engagement units 1315 are provided to correspond to the two second engagement units 1316, respectively.
It should be understood that the number and positions of the first and second coupling units 1315 and 1316 are not limited thereto. For example, the number of the first and second bonding units 1315 and 1316 may be three or more, respectively. For example, in the view shown in fig. 5, the first bonding unit 1315 may also be disposed on the back side of the upper seal 1311.
The base member 130 is opened at an end portion in the longitudinal direction with a groove 1302, and the upper seal 1311 and the left and right side seals are accommodated in the groove 1302. The thickness of the upper seal 1311 in the longitudinal direction is smaller than the depth of the portion of the groove 1302a of the groove 1302 that accommodates the upper seal 1311. Thereby, when the upper seal 1311 is pushed down, the upper seal 1311 can smoothly move down.
The base member 130 is provided with a guide portion, and the upper seal 1311 is movable downward from the non-sealing position to the sealing position under the guide of the guide portion. The guide portion is a projection extending from the bottom surface of the partial groove 1302 a. The upper seal 1311 is provided with a corresponding channel and the boss can slide down the channel. Thus, when pushed downward, the upper seal 1311 does not tilt to prevent being caught and unable to move downward, thereby affecting the sealing effect.
Embodiments have been described above in which the guide is in the form of a projection. However, it should be understood that the guide portion may have other configurations known in the art as long as the upper seal 1311 is smoothly moved downward. For example, the guide portion is a recess recessed from the bottom surface of the partial groove 1302a, the upper seal 1311 is provided with a protrusion, and the protrusion can slide downward along the recess.
The base member 130 is further provided with an oil reservoir and an oil hole to provide lubrication for the linear guide system according to an embodiment of the present invention.
According to an embodiment of the present invention, the pair of side seals 1312, 1313 may be formed by an injection molding process and may be a rubber or plastic material.
Some exemplary embodiments of the present invention are described above with reference to the drawings, however, these embodiments are merely illustrative. Those skilled in the art can appropriately combine and/or modify the respective embodiments without departing from the spirit and scope of the present invention. The scope of the present invention should be determined with reference to the appended claims.
