Description

Technical Field

[0001] The utility model relates to a linear motor device, which comprises a linear motion component. The linear motion component comprises a linear moving part and a guide part, wherein the linear moving part is arranged on the guide part and can move along the longitudinal direction of the guide part. Background Art

[0002] Linear motor devices have been widely used as a component for realizing linear reciprocating motion. Traditional linear motor devices usually include a motor, a lead screw, a linear motion component, that is, generally a linear moving part and a guide part. The motor drives the lead screw to rotate, and the linear moving part engaged with the thread of the lead screw can thus reciprocate linearly along the guide part. The movement of the linear moving part is generally limited by a limit switch.

[0003] In the existing linear motor device, the guide member is integrally formed by using a profile. The disadvantage of this design is that, due to the use of an extrusion molding process, the guide member has the same cross section in the longitudinal direction of the guide member, which leads to a complex structure of the guide member and waste of materials. Finally, the manufacturing cost through integral molding, especially extrusion molding, is also relatively high. Utility Model Content

[0004] The technical problem to be solved by the utility model is to realize a linear motor device, through which the above-mentioned disadvantages existing in the prior art are overcome.

[0005] The above technical problem is solved by a linear motor device according to the utility model, that is, a linear motor device, which includes a linear motion component, the linear motion component includes a linear moving member and a guide member, wherein the linear moving member is arranged on the guide member and can move along the longitudinal direction of the guide member, wherein the guide member is composed of at least two side surfaces and a bottom surface, wherein the two side surfaces are arranged relative to each other, and the bottom surface connects the two side surfaces to each other, wherein at least one side surface includes at least one protruding protrusion protruding inward, and the protrusion only partially extends in the longitudinal direction of the guide member. In other words, the protrusion has a first extension along the longitudinal direction of the guide member, and the side surface has a second extension along the longitudinal direction of the guide member, wherein the first extension is less than the second extension. In the utility model, the longitudinal direction of the guide member refers to the direction along which the linear moving member moves in a linear reciprocating motion on the guide member.

[0006] According to the utility model, at least one side surface includes at least one protruding protrusion protruding inward, and the protrusion only partially extends in the longitudinal direction of the guide member. In the design according to the utility model, the guide member is not the same everywhere in the cross section perpendicular to the longitudinal direction of the guide member (but the protrusion is only partially constructed on the side surface), so that a cross section that can achieve a specific function can be set at a specific position of the guide member without having to keep the same cross section always set in the longitudinal direction of the entire guide member, thereby achieving a simpler structure than the guide member manufactured by the extrusion molding process and saving materials used to manufacture the guide member.

[0007] According to a design scheme, the linear motor device also includes a limit switch device, the longitudinal movement of the linear moving member along the guide member is limited when the linear moving member manipulates the limit switch device, the limit switch device is fixed to the bottom surface at least by the protrusion, and the limit switch device may include a substrate member and at least one limit switch arranged on the substrate member, the substrate member is configured as an elongated strip and fixed between the protrusion and the bottom surface. In the prior art, when the limit switch is fixed inside the guide member, it is difficult to replace or repair the failed limit switch. The limit switch device is fixed to the bottom surface at least by the protrusion, which facilitates the installation of the limit switch device. That is, since the protrusion protrudes from the side in the longitudinal direction of the guide member at a part of the side, the installation position of the limit switch device can be more easily approached. Preferably, two limit switches can be set, thereby realizing that the linear moving member can manipulate the limit switch at the starting point and the end point of the movement respectively during its longitudinal movement along the guide member. By arranging the limit switch on the long strip-shaped substrate member, the limit switch device can be more conveniently positioned between the protrusion and the bottom surface so as to be fixed.

[0008] The limit switch device can also be designed to be composed of only limit switches, that is, the limit switch is not arranged on the substrate member. In this case, a single limit switch can also be positioned and fixed between the protrusion and the bottom surface. This can save the component cost caused by the substrate member and the installation cost of arranging the limit switch with the substrate member on the substrate member. In addition, the single limit switch can also be flexibly changed in its installation position, thereby adjusting the stroke of the linear moving member along the longitudinal linear movement of the guide member. In addition, when there are multiple limit switches, when the limit switch fails, only the limit switch that fails can be replaced, without replacing the entire substrate member with the failed limit switch.

[0009] According to one design, a plurality of protrusions may be provided. Preferably, two, three or more protrusions may be provided. By providing a plurality of protrusions, the limit switch device may be more reliably fixed. The plurality of protrusions may be distributed at uniform intervals on the side surface, or may be distributed at uneven intervals. In addition, the extension amounts of the plurality of protrusions along the longitudinal direction of the guide member may be the same or different.

[0010] According to one design, the protrusion can be constructed as a separate fixing member, which is connected to the side surface. By designing the protrusion and the side surface separately, the two components can be designed and manufactured independently of each other, which is beneficial to the mutual adaptation between protrusions and side surfaces of different specifications, and can also avoid the entire guide being regarded as waste due to unqualified products in the protrusion or side surface or guide during the manufacturing process. According to this design, the fixing member can be connected to the side surface by riveting, bonding or welding.

[0011] According to one design, the protrusion is integrally constructed with the side surface. The integral construction of the protrusion and the side surface ensures the connection strength between the protrusion and the side surface and thus improves the stability of the protrusion on the side surface. In addition, compared with a split design, the integral construction of the protrusion and the side surface avoids the use of additional fixing devices and processes for achieving fixing, thereby reducing the complexity and cost of installation.

[0012] According to a design solution, the protrusion can be formed by bending the free end of the side surface toward the inside of the guide member. This design of the protrusion has a simple structure and is easy to manufacture, thereby reducing the manufacturing cost.

[0013] According to one design, the protrusion may have a first groove for fixing the limit switch device on the side thereof facing the bottom surface. The limit switch device is fixed in the groove on the side of the protrusion, which can make the fixation of the limit switch device more stable and therefore more reliable. According to this design, the first groove may extend in the longitudinal direction of the guide. In addition, the first groove may also extend in a direction perpendicular to the longitudinal direction of the guide. The different extension directions of the first groove are also conducive to the installation of the limit switch device in the corresponding direction. In this case, it is relatively simple and convenient that the first groove is formed by bending the protrusion, for example, by a stamping method.

[0014] According to a design, the bottom surface may have a second groove for clamping the limit switch device on the side facing the protrusion. The second groove may exist alone or as a supplement to the first groove. The second groove is used to clamp the limit switch device alone or in cooperation with the first groove. According to this design, the second groove may extend in the longitudinal direction of the guide. In addition, the second groove may also extend in a direction perpendicular to the longitudinal direction of the guide. The different extension directions of the second groove may also facilitate the installation of the limit switch device in the corresponding direction. In addition, if the second groove extends along the longitudinal direction of the guide, the entire guide can be additionally strengthened. In this case, it is relatively simple and convenient that the second groove is formed by bending the protrusion, for example, by a stamping method. In addition, the second groove may also be constructed on a separate groove member, and the groove member is connected to the bottom surface. By designing a separate groove member, it is possible to omit the manufacturing of a groove in the bottom surface of the guide and achieve, for example, that a bottom surface of a guide can be adapted to a variety of different groove members.

[0015] According to one design, the linear motor device may further include end caps arranged at the two longitudinal ends of the guide. The end caps may prevent foreign matter from entering the interior of the guide and may also be used to support the screw or the motor of the linear motor device. Here, the limit switch device may extend over the entire longitudinal extension of the guide so as to rest in a fixed position between the two end caps. In this way, the limit switch device may be additionally fixed over the longitudinal extension of the guide without the need for other auxiliary fixing devices.

[0016] According to one design, the limit switch device is bonded or welded or fixed to the side surface by other means. Thus, the limit switch device is further fixed by bonding or welding to the side surface in addition to being fixed to the bottom surface by the protrusion, thereby improving the position stability of the limit switch device.

[0017] According to one design, the guide member is provided with a receiving portion for receiving a screw at two longitudinal ends by means of the curling portions of the side surfaces. By forming the curling portions on the side surfaces of the longitudinal ends of the guide member, it can be used to form a screw connection with the screws in order to fix other components, such as an end cap of the guide member.

[0018] According to one design, a hole can be provided in the side surface for the auxiliary fixing member to pass through, and the limit switch device can be fixed to the side surface by means of the auxiliary fixing member, thereby achieving better fixation of the limit switch device by clamping the limit switch device.

[0019] According to one design solution, the auxiliary fixing element is a screw or a pin.

[0020] According to one design, the surface of the guide member may be treated with an anti-corrosion treatment. This can expand the scope of use of the linear motor device according to the utility model. The surface of the guide member may also not be treated with an anti-corrosion treatment, but may be made of a material that has an anti-corrosion property, thereby reducing manufacturing costs and / or saving steps.

[0021] According to one design, the guide part can be constructed in one piece. According to one design, the guide part can be made by casting and / or stamping. This is less expensive than an extrusion molding process.

[0022] According to a design solution, the side surface and the bottom surface can be connected to each other by welding, thereby being able to adapt to different specifications of the side surface of the bottom surface.

[0023] According to one embodiment, the guide element may include steel, zinc, magnesium or aluminum. The guide element may also include a steel alloy. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 4 A three-dimensional view showing a guide member of a linear motor device according to one embodiment of the present utility model is shown.

[0029] Figure 5 It is shown that according to one embodiment of the present invention, a limit switch device with a limit switch and a substrate member is installed in the guide member. DETAILED DESCRIPTION

[0030] Figure 1The linear motor device shown in the figure comprises a motor 1, a screw rod 3, an end cap 4, a linear motion assembly and a limit switch device not shown here. The linear motion assembly at least comprises a linear moving member 2 and a guide member 5, the linear moving member 2 is supported on the guide member 5, the motor 1 drives the screw rod to rotate so that the screw rod 3 engages with the linear moving member to make the linear moving member reciprocate linearly on the guide member 5 along the longitudinal direction A of the guide member 5. The movement of the linear moving member is limited when it operates the limit switch device, so that it stops at the current position or returns to the starting position.

[0031] The guide member 5 has two mutually opposite side surfaces 6 and a bottom surface 8 connecting the two side surfaces 6 , thereby forming a substantially U-shaped cross section of the guide member 5 . The limit switch device is arranged on at least one side surface 6 of the guide member 5 .

[0032] As mentioned above, the limit switch device can limit the linear movement of the linear moving member 2 together with the mechanical parts connected thereto, and therefore, the limit switch device should be installed in a fixed position relative to the longitudinal direction A of the guide member 5. To this end, the side 6 includes a protruding portion 7 protruding inwardly, and the protruding portion only partially extends in the longitudinal direction of the guide member, that is, the extension amount of the protruding portion along the longitudinal direction A of the guide member 5 is less than the extension amount of the side along the longitudinal direction A of the guide member 5. As a result, the guide member 5 does not have a continuous, constant cross-section along the longitudinal direction A, but has a variable cross-section.

[0033] The bottom side of the raised portion 7 and the top side of the bottom surface 8 are generally opposite to each other. Through the mutual cooperation between the raised portion 7 and the bottom surface 8, the limit switch device can be fixedly installed inside the guide member 5 relative to the longitudinal position A of the guide member 5, so that the limit switch device can be operated when the linear moving part slides on the guide member 5 along the longitudinal direction A of the guide member 5.

[0034] The limit switch device can be designed to realize the limit function. For example, (see Figure 5) The limit switch device may include a substrate member 15 and a limit switch 14 arranged on the substrate member 15, wherein the substrate member 15 is configured as an elongated strip and fixed between the protrusion 7 and the bottom surface 8. Generally, two limit switches 14 may be arranged on the substrate member 15 to correspond to the starting point and the end point of the linear motion of the linear moving member along the guide member. Preferably, more limit switches 14 may be arranged on one substrate member 15. Or each limit switch 14 may be arranged separately on one substrate member. In addition, in an embodiment not shown in the figure, the limit switch device may also be composed only of the limit switch 14, that is, the limit switch 14 is not arranged on the substrate member 15. Therefore, in the design according to the present utility model, at least the limit switch 14 itself may be fixed by the protrusion 7 on the bottom surface 8 of the guide member 5 and the side surface 6 of the guide member 5, or the substrate member 15 on which the limit switch 14 is arranged, which further depends on the specific design of the limit switch device.

[0035] In such Figure 2 In the illustrated embodiment, three protrusions 7 are provided on the side surface 6 of the guide member 5. However, in other feasible embodiments not shown, one, two or other number of protrusions may be provided as required.

[0036] The projection 7 is formed by bending or folding the free end of the side surface 6 toward the inside of the guide member 5. In other words, the projection 7 is formed integrally with the side surface 6. By designing the projection 7 and the side surface 6 as an integral structure, the projection 7 can be realized in the side surface 6 in a simple manner. This reduces the manufacturing cost of the projection.

[0037] However, in other possible embodiments not shown, the projection 7 may also be configured as a separate fixing element and connected to the side surface, for example, by riveting, bonding or welding.

[0038] In order to further enhance the positioning reliability of the limit switch device, such as Figure 3 As shown in the enlarged view of one end of the guide member 5, the protrusion 7 has a first groove 9 for clamping the switch limit device on the side facing the bottom surface 8. The first groove 9 is formed by bending the protrusion 7, such as stamping. The first groove 9 is close to the side 6 from which the protrusion 7 originates, and extends substantially along the longitudinal direction A of the guide member 5. The three protrusions 7 arranged at the side 6 all have the first groove 9, and the three first grooves 9 extend substantially along the same straight line, so that the limit switch device can be reliably clamped from the upper edge thereof in cooperation with each other.

[0039] In an embodiment not shown, of course, the first groove 9 may also be provided on only one or two protrusions 7 .

[0040] In addition, in an embodiment not shown in the figure, the first groove 9 may also extend in a direction perpendicular to the longitudinal direction A of the guide member 5. The extension direction of the first groove 9 depends on the orientation of the component on the limit switch device that should cooperate with the first groove, such as the limit switch 14 or the substrate member 15, thereby facilitating the installation of the limit switch device. For example, when the longitudinally extended limit switch device is not arranged along the longitudinal direction A of the guide member 5 with its longitudinally extended substrate member 15, but a plurality of limit switches 14 need to be directly fixedly installed in the guide member 5, a matching component extending perpendicular to the longitudinal direction A, such as a fixing pin, may be provided on the limit switch 14, and the fixing pin can be embedded in the first groove 9, thereby positioning the limit switch device at the corresponding position of the guide member 5.

[0041] In addition, in an embodiment not shown in the figure, the substrate member 15 can also be arranged on different sides of the limit switch 14, so that, for example, the substrate member extending along the longitudinal direction A of the guide member 5 can be clamped in the first groove 9 that also extends along the longitudinal direction A of the guide member 5, or the substrate member extending in a direction perpendicular to the longitudinal direction A of the guide member 5 can be clamped in the first groove 9 that also extends in the longitudinal direction A of the guide member 5.

[0042] like Figure 3 As shown, the bottom surface 8 is provided with a second groove 10 on its top side facing the protrusion 7. The second groove 10 can be formed by bending the bottom surface, for example, by stamping. In addition, in an embodiment not shown, the second groove 10 can be constructed on a separate groove member, which is connected to the bottom surface of the guide member. The second groove 10 is close to the protrusion 7 in a direction perpendicular to the longitudinal direction A, and extends in the longitudinal direction A of the guide member 5. The second groove 10 can reliably clamp the limit switch device from its lower edge.

[0043] Similar to the first groove 9, the second groove 10 and the first groove 9 can extend along the longitudinal direction A of the guide member 5. However, in another embodiment not shown, the second groove 10 can also extend in a direction perpendicular to the longitudinal direction A of the guide member 5. The extension direction of the second groove 10 depends specifically on the component that cooperates with the groove on the limit switch device to be fixed thereto, such as the orientation of the limit switch 14 or the substrate member, thereby facilitating the installation of the limit switch device.

[0044] The second groove 10 can extend over the entire extension of the bottom surface in the longitudinal direction A, which can additionally achieve the effect of structurally reinforcing the guide 5. As an alternative, the second groove 10 can extend only in a part of the bottom surface 8 opposite to the protrusion 7 or the first groove 9 in the protrusion 7.

[0045] In such Figure 3In the illustrated embodiment, the first groove 9 and the second groove 10 cooperate with each other to simultaneously clamp the limit switch device from the upper and lower sides. However, in an embodiment not shown, only the first groove 9 or only the second groove 10 may be provided. In addition, in other feasible embodiments not shown, as an alternative or supplement to the first groove and / or the second groove, a through hole for the clamping piece to pass through may be provided on the protrusion 7, so as to, for example, thread the limit switch device on the protrusion 7.

[0046] like Figure 1 As shown, the linear motor device further comprises a first end cap 4 arranged at the longitudinal end of the guide member 5, the first end cap 4 closes the guide member 5 at the end and supports the end of the lead screw. A second end cap is also arranged opposite to the first end cap 4 along the longitudinal direction A of the guide member 5.

[0047] like Figure 5 As shown, the limit switch device can extend over the entire longitudinal extension of the guide 5, and therefore has the same extension as the longitudinal extension of the guide 5. As a result, when the limit switch device is fixed between the protrusion and the bottom surface, it can rest between the two end caps in a fixed position, and this design can additionally fix the limit switch device in the longitudinal direction A of the guide 5.

[0048] exist Figure 5 It can also be seen from the figure that according to one embodiment, a total of three protrusions are arranged on the side 6 of the guide member 5, which are distributed at uneven intervals, so that certain parts of the limit switch device can be fixed to different degrees than other parts. In other words, the limit switch device can be better fixed at the position where the protrusions 7 are arranged at smaller intervals. In addition, it can be seen from the figure that the protrusions 7 arranged on the side 6 have different extensions along the longitudinal direction A of the guide member.

[0049] In one embodiment, if Figure 2 and Figure 3 As shown, the guide 5 forms a receiving portion for receiving a screw at both ends by means of a flanged portion of the side 6. Figure 3 The first curling part 11 and the second curling part 12 at one end are shown in FIG. In this way, the end cover can be fixed by screws in a simple manner. For example, the end cover can be provided with a matching receiving hole aligned with the first curling part 11 and the second curling part 12, and the screw can be screwed into the first curling part 11 and the second curling part 12 through the matching receiving hole in the end cover, so as to fix the end cover on the guide member 5.

[0050] In one embodiment, the limit switch device can be fixed on the side by bonding or welding, so that the limit switch device is not only fixed by the protrusion 7 and the bottom surface of the guide member 5, but also additionally fixed more stably by bonding or welding with the side.

[0051] like Figure 4 As shown, a hole 13 through which an auxiliary fixing member can pass can be additionally provided in the side surface 6, by means of which the limit switch device can be fixed on the side surface 6. In this way, the limit switch device can be additionally fixed on the side surface relative to the protrusion 7 and the bottom surface 8, so that the position of the limit switch device is more stable. The auxiliary fixing member can be, for example, a screw or a pin.

[0052] In one embodiment, the surface of the guide member 5 is treated with an anti-corrosion treatment, thereby making the application range of the guide member and the linear motor device with the guide member wider. Alternatively, the surface of the guide member 5 may also not be treated with an anti-corrosion treatment.

[0053] In one embodiment, the guide member 5 can be constructed in one piece, which can be achieved by casting or simply punching, bending or curling the plate, which saves the cost of the mold compared to the extrusion integral molding.

[0054] In one embodiment, the side surface 6 and the bottom surface 8 of the guide member 5 can also be connected to each other by welding. The advantage is that different specifications of different components of the guide member, such as the bottom surface and the side surface, can be adapted.

[0055] In one embodiment, the guide member 5 comprises steel, magnesium, zinc or aluminum. Compared with aluminum, steel has the advantages of low cost and easy stamping. In addition, the guide member can also comprise a steel alloy.

[0056] Finally, according to the utility model, the guide part of the linear motor device is particularly simple in structure compared with the guide part manufactured by the extrusion molding process in the prior art, and because the structure (such as the protrusion, the curling part) for realizing such function is only designed at the position where a certain function needs to be realized (such as the position of the fixed limit switch device, the position of the fixed end cover), a large amount of material is also saved, because the parts manufactured by the extrusion molding process always have a continuous identical cross-section.

[0057] Although the present invention has been described in detail through the preferred embodiments, the present invention is not limited to the disclosed embodiments, and a technician may make other changes without departing from the protection scope of the present invention.
