Description

  The present invention provides a linear module system, and more particularly, an oil tank that can be directly replaced on the outside of the linear module system, and between the upper surface of the guideway and the top surface of the slider. Provided is a linear guideway that can directly perform the work of replacing the space between them.

  In fact, while improving the research and development of various precision feeding systems, each precision linear mechanism product is already widely used in human life, processing factory or high technology equipment. As such, linear guideway technology demands that consumer products need to further improve the technical effectiveness of their products, despite the fact that they develop fairly quickly. Thus, there are a number of problems for the advanced development of linear products (eg, linear guideways). In response to this, such a technological industry has already been actively engaged in research and development to effectively improve each new idea or new invention related to the linear guideway technology. In particular, a lot of industrial equipment that is manufactured more stably or statically with high precision is required (for example, wafer processing equipment, CNC equipment, etc.), but the existing linear mechanism technology still has some blind spots. Therefore, improvement is expected by the research and development of each supplier.

  Actually, the linear guideway structure used in the market consists of a guideway, a ball cage, a slider, an end cover, an oil tank, and the like (other scrapers are also disposed. The description here is omitted). Most of the sliders include a combination of an end cover and an oil tank at both ends of the slider, and each of the combined members is slidable to the outside of the guideway. (Each member is blended in sliding contact with the guideway). A general description of the members will give a better understanding of the conventional product structure.

  After the conventional product as described above has been put into practical use, it has certainly become mainstream in the market, but the oil tank member therein always keeps the user in trouble with the following problems.

  One is that oil must always be added to the oil tank. The user bends the body, puts his hand in the space between the upper surface of the guideway and the top surface of the slider, and further supplies oil using a tool. Not only that, but also the oil supply work is quite troublesome and time consuming.

  The second is that oil tanks must always be replaced and maintained. However, the oil tank body is arranged so that it slides outward from the guideway, and its lower edge is in sliding contact with the guideway. Only after removing the oil tank can the oil tank be removed. For this reason, all operations for all mechanisms must be stopped, and the operation takes time or man-hours, and the cost required for the linear guideway system is increasing.

  Third, the existing disposable parts are already mainstream in the market. However, the conventional oil tank is limited to the structure in which the lower edge and the guideway are blended in sliding contact with each other, so the design concept of the disposable oil tank could not be adopted. It is also a weak point.

  Although the problems in the oil tanks of the linear mechanism used in the past cannot be said to be small due to the problems of the products mentioned above, today we are really striving for ideal, practical or progressive products for the above defects. I think it is a goal that should be pursued and improved.

  In view of the above, the present inventor has developed a linear guideway having a replaceable oil tank by taking advantage of accumulated technical experience of each linear guideway product or linear guideway over many years as a result of detailed research. The space between the top surface of the guideway and the top surface of the slider is used to directly replace this replaceable oil tank, and the number of oil tanks that can be replaced according to the assembly design without screws In addition to simplifying the work process, the cost of assembly or maintenance can be greatly reduced.

  An object of the present invention is to provide a linear guideway including a replaceable oil tank that can mainly perform a replacement operation directly. The replaceable oil tank of the present invention has a square shape including both extended legs, and the inner edge of the replaceable oil tank is not aligned with the guideway, and this replaceable oil tank is located above the guideway. The distance between the surface and the top surface of the slider can be advanced. Therefore, according to the present invention, the replacement work of the replaceable oil tank can be performed directly using the space between the upper surface of the guideway and the top surface of the slider. In addition to shortening the number of man-hours for oil tanks that can be replaced, the work process can be simplified, and costs such as assembly and maintenance can be greatly reduced.

  Another object of the present invention is to provide a linear guideway having a replaceable oil tank having the design concept of a disposable oil tank. The present invention can directly replace the replaceable oil tank by utilizing the space between the upper surface of the guideway and the top surface of the slider, and further replace the oil tank according to the assembly design without screws. In order to reduce the number of possible oil tanks, the present invention meets the demands of ergonomics and cost reductions, and further meets the design concept of disposable oil tanks, effectively increasing the competitiveness of products in the market. Can be improved.

  In the structural design of the present invention, a replaceable oil tank is installed on the outside of the end cover, the replaceable oil tank is formed in a square shape having legs that are both extended, and the replaceable oil tank The inner edge is not aligned with the guideway, the width of both extended legs is larger than the maximum width of the guideway, and the maximum width of the replaceable oil tank main body is the top surface of the guideway and the top of the slider. It is formed smaller than the distance to the surface. The replaceable oil tank can be replaced directly in the space between the upper surface of the guideway and the top surface of the slider, and the replaceable oil tank of the replaceable oil tank can be adapted to the assembly design without screws. The number of work steps can be shortened, the work process can be simplified, and the cost required for assembly and maintenance can be greatly reduced.

  In order to achieve the above-mentioned object, the present invention will be described in detail with respect to advanced technical ideas and means employed as preferred embodiments with reference to the drawings.

  The objects, features and other advantages of the present invention are believed to be deeper and more concretely understood and will be further described with reference to FIGS.

  The linear guideway having a replaceable oil tank according to the present invention includes a guideway 10, a slider 20, both connectors 30, and both oil tanks 40, the structure of which will be described in detail below.

  The guideway 10 is provided with uneven rail structures 11 on both sides. An end cover 21 is attached to both ends of the slider 20, and both the slider 20 and the end cover 21 are disposed on the rail structure 11 of the guideway 10, and a connecting base having an internal thread on the end surface of the end cover 21. 211 is established. The connection base 211 is connected to the slider 20 and the lubricating oil passage in the end cover 21.

  The connection tool 30 is provided with a connection part 31 provided with a screw at both ends thereof, and the connection tool 30 is screwed onto the connection base 211 of the end cover 21 of the slider 20 by the connection part 31. A fitting portion 33 is installed at the other end corresponding to the connection portion 31, and an engagement groove 331 is provided in a step portion where the fitting portion 33 is previously installed, and a protrusion is provided between the connection portion 31 and the fitting portion 33. An oil guide hole 34 is formed through the ring 32 in the axial direction with the ring 32 interposed therebetween.

  The oil tank 40 (see FIGS. 7 and 8) is formed in a square shape using the main body 401 and both extended legs 402, and the width a of both extended legs 402 is a rail structure of the guideway 10. 11 and the maximum width b of the U-shaped body 401 of the oil tank 40 is smaller than the distance c between the upper surface of the guideway 10 and the top surface of the slider 20. The oil tank 40 shown in FIGS. 4, 5 and 6 is composed of a housing 41 and a cover 42 (the joining method can be ultrasonic, friction welding, thermal welding, glue, etc.), and an oil storage tank in the housing 41. 411 and the oil supply hole 412 are opened. Further, an elastically deformable rubber plug 413 is provided so as to seal the oil supply hole 412. Further, the oil discharge hole 414 is opened so that the oil discharge hole 414 is fitted to the fitting portion 33 of the connector 30. An engagement protrusion 415 is installed in the engagement groove 331 corresponding to the attachment portion 33. The integral oil tanks in FIGS. 1, 2 and 3 are integrally molded by blow molding technology, so in FIGS. 1, 2 and 3 there is a distinction between structures such as housing 41 and cover 42 (characteristics of the present invention and The description of the design of both oil tanks is omitted), and the structural features of the above embodiments and the ingenious positions of each other are omitted. According to the general arrangement, the above-mentioned basic object of the present invention can be achieved by further combining the operation principles between the members.

  Next, in order for the examiner to better understand and recognize the structure, features and other advantages of the present invention, the operation principle of the present invention will be described in detail with reference to the drawings as follows.

  Further, in order to explain that the present invention has more advanced and practical advantages than the known structure, and to make it more clear, further refer to the operation diagram of the embodiment in the present invention shown in FIG.

  In the present invention, when the oil tank 40 has to be replaced, the main body 401 and the both extended legs 402 of the oil tank 40 are formed in a square shape, and the width a of the both extended legs 402 is a guide. Since the maximum width a of the rail structure 11 of the way 10 is larger than the maximum width a, the inner edge of the oil tank 40 of the present invention is not aligned with the rail structure 11 of the guide way 10 and the width a of the both extended legs 402 is equal to the rail structure 11. In the design larger than the maximum width d, both extended legs 402 of the oil tank 40 are allowed to escape directly from the vicinity of the rail structure 11 (see FIG. 7). Further, according to the present invention, the U-shaped main body portion 401 is adapted to a design in which the maximum width b of the U-shaped body portion 401 of the oil tank 40 is smaller than the distance c between the upper surface of the guideway 10 and the top surface of the slider 20. Since the present invention can rotate within the distance c, the user can easily rotate the oil tank 40 out of the rail structure 11 of the guideway 10 to escape. Further, as shown by an arrow in FIG. 9, the oil tank 40 can be directly taken out from the distance c between the upper surface of the guideway 10 and the top surface of the slider 20. Therefore, according to the present invention, the replacement work of the replaceable oil tank can be performed directly, and at the same time, the costs of assembly and maintenance are greatly reduced.

  In the present invention, the connection portion 31 of the connection tool 30 is screwed onto the connection base 211 of the end cover 21 of the slider 20, and the fitting portion 33 at the other end of the connection portion 31 is connected to the oil discharge hole 414 of the oil tank 40. The fitting groove 331 of the fitting portion 33 of the connector 30 can be sealed in accordance with the engagement protrusion 415 of the oil tank 40. Therefore, the oil tank 40 of the present invention has an assembly design without a screw, further reduces the man-hours for replacing an oil tank that can be replaced in accordance with the assembly design without a screw, and requires human engineering and cost reduction. Therefore, it is a linear guideway equipped with a replacement oil tank that can surely realize the design concept of a disposable oil tank and can effectively improve the competitiveness of products in the market.
