Description

Technical Field

[0001] This application relates to the field of nut installation technology, and more particularly to a nut positioning and installation device. Background Technology

[0002] Bolted connections are commonly used to join two separate parts together. For example, after a bolt passes through holes in two parts, a nut is tightened onto the bolt, thus connecting the two parts together.

[0003] In the prior art, when making bolted connections, it is generally necessary to position the nut, for example, by placing the nut flat in the positioning groove, then placing two parts on top of the nut and aligning the holes on the parts with the nut, then the bolt passes through the holes of the two parts and extends into the nut, and the bolt is tightened to connect the bolt to the nut.

[0004] However, if the bolt torque is too high during the tightening process, the nut may get stuck in the positioning groove, making it difficult to separate the nut from the positioning groove. Summary of the Invention

[0005] This application provides a nut positioning and mounting device to facilitate the positioning of the nut before connecting the bolts and the separation of the nut after connecting the bolts.

[0006] The nut positioning and mounting device provided in this application includes:

[0007] A part support plate, the upper surface of which is a part support surface, a first nut positioning groove is provided on the first edge of the part support surface, and a first opening is provided on the side of the first nut positioning groove away from the first edge;

[0008] A movable plate, disposed to the side of the part support plate, the movable plate having a second edge facing the first edge, a second nut positioning groove formed on the upper surface of the second edge, and a second opening provided on the side of the second nut positioning groove facing the first edge; and

[0009] A first drive assembly, connected to the movable plate, drives the movable plate to move between a relaxed position and a clamped position.

[0010] When the movable plate is in the clamping position, the distance between the first opening and the second opening is a first distance, so that the first nut positioning groove and the second nut positioning groove together clamp the nut.

[0011] When the movable plate is in the relaxed position, the distance between the first opening and the second opening is a second distance greater than the first distance, so that the second nut positioning groove is separated from the nut.

[0012] Compared with the prior art, this application includes at least the following beneficial effects:

[0013] The nut positioning and mounting device of this application achieves nut clamping and loosening by setting a first nut positioning groove and a second nut positioning groove that can move closer to or further away from each other. When the nut needs to be positioned, the first and second nut positioning grooves clamp the nut; when the nut needs to be removed, the first and second nut positioning grooves loosen the nut. This solves the problem of nuts easily getting stuck in the positioning grooves. Attached Figure Description

[0033] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not all of them.

[0034] This application defines certain directional terms. Unless otherwise stated, the directional terms used, such as "up," "down," "left," "right," "inner," and "outer," are used for ease of understanding and therefore do not constitute a limitation on the scope of protection of this application.

[0035] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] like Figure 1 As shown, the pump 100 includes a pump body 110 and a motor 120. The pump body 110 and the motor 120 are connected by bolts 130 and nuts 140. Specifically, the thread 131 of the bolt 130 passes through the motor 120 and the pump body 110 successively and is connected to the nut 140, so that the pump body 110 and the motor 120 are clamped between the nut 140 and the bolt cap 132. In this embodiment, the nut 140 is a hexagonal nut 140.

[0038] It should be noted that although this application only uses pump 100 as an example to illustrate that pump body 110 and motor 120 can be fixed by bolt 130, those skilled in the art will understand that bolt 130 connection can also be applied to other scenarios, as long as two independent parts can be connected by bolt 130.

[0039] like Figure 1 As shown, in the process of connecting the pump body 110 and the motor 120, the nut 140 is usually placed flat in the positioning groove first, then the pump body 110 is placed on top of the nut 140 and the hole on the pump body 110 is aligned with the nut 140. Next, the motor 120 is placed on top of the pump body 110 and the hole on the motor 120 is aligned with the hole on the pump body 110. Finally, the bolt 130 is passed through the motor 120 and the pump body 110 from top to bottom and screwed into the nut 140.

[0040] However, after the connection between the pump body 110 and the motor 120 is completed, the nut 140 will be stuck in the positioning groove due to the torque of the bolt 130, and thus the entire pump 100 cannot be removed from the positioning groove.

[0041] To address the aforementioned issues, this application provides a nut positioning and installation device. For each nut 140, a first nut positioning groove and a second nut positioning groove, which can move closer to or further away from each other, are used to clamp and loosen the nut 140. When the nut 140 needs to be positioned, the first nut positioning groove and the second nut positioning groove clamp the nut 140. When the nut 140 needs to be removed, the first nut positioning groove and the second nut positioning groove loosen the nut 140. This solves the problem that the nut 140 is easily stuck in the positioning groove.

[0042] The structure of the nut positioning and mounting device is described in detail below.

[0043] like Figure 2 As shown, the nut positioning and mounting device includes a first base plate 200 and a positioning component 300 mounted on the upper surface of the first base plate 200. The positioning component 300 is used to position the nut 140, and in particular, can clamp and loosen the nut 140.

[0044] like Figure 3 As shown, the positioning component 300 includes a part support plate 310, a movable plate 320, and a first drive component 330. The number of movable plates 320 can be one or more, and the number of first drive components 330 matches the number of movable plates 320. In this embodiment, two movable plates 320 are used as an example. Specifically, two movable plates 320 are respectively disposed on opposite sides of the part support plate 310. Each movable plate 320 is connected to a first drive component 330.

[0045] like Figure 3 As shown, the component support plate 310 is fixedly disposed relative to the first substrate 200. The upper surface of the component support plate 310 is the component support surface 311. Specifically, in the embodiment of this application, the component support surface 311 is used to support the lower end of the pump body 110. That is, when connecting the pump body 110 and the motor 120, the lower end of the pump body 110 is placed on the component support surface 311.

[0046] like Figure 3 As shown, a first nut positioning groove 3121 is formed on the first edge 312 of the support surface 311 of the part. Specifically, in Figure 3 In this embodiment, the left and right sides of the component support surface 311 are both first edges 312, meaning there are two first edges 312. However, in other embodiments, the number of first edges 312 may be one or more. Furthermore, the first edges 312 may also be located on the upper and / or lower side of the component support surface 311.

[0047] like Figure 3 As shown, for each first edge 312, the number of first nut positioning grooves 3121 can be one or more. For example, in... Figure 3 In the design, each first edge 312 has two first nut positioning grooves 3121. Furthermore, the number of first nut positioning grooves 3121 on different first edges 312 can be the same or different. For example, the left first edge 312 has two first nut positioning grooves 3121, and the right first edge 312 has one first nut positioning groove 3121.

[0048] like Figure 3 As shown in the embodiment of this application, a first opening 3122 is provided on the side of the first nut positioning groove 3121 away from the first edge 312. For example, for the right side of the first edge 312, the first opening 3122 of the first nut positioning groove 3121 is located on the right side of the first nut positioning groove 3121.

[0049] It should be noted that the shape of the first nut positioning groove 3121 can be half the shape of the nut 140, so that when the nut 140 is placed in the first nut positioning groove 3121, the nut 140 can be positioned by the first nut positioning groove 3121. That is, the shape of the first nut positioning groove 3121 can be half a regular hexagon. In addition, the shape of the first nut positioning groove 3121 can also be smaller than half the shape of the nut 140. That is, the shape of the first nut positioning groove 3121 can be smaller than half a regular hexagon.

[0050] like Figure 3 As shown in this embodiment, the component support plate 310 includes a left side plate 313, a middle plate 314, and a right side plate 315 connected sequentially from left to right. The left edge of the left side plate 313 is the first edge 312, and the right edge of the right side plate 315 is the first edge 312. A first nut positioning groove 3121 is provided on the left edge of the left side plate 313 and the right edge of the right side plate 315.

[0051] In addition, grooves are provided on the middle plate 314 and the right side plate 315. The grooves are used to accommodate the protrusion at the lower end of the pump body 110, so that when the pump body 110 is placed on the upper surface of the part support plate 310, it can be placed stably on the part support surface 311 without tilting.

[0052] like Figure 3 As shown, the movable plate 320 is disposed on the side of the part support plate 310. Specifically, in Figure 3 In the middle, the left movable plate 320 is located to the left of the part support plate 310, and the right movable plate 320 is located to the right of the part support plate 310.

[0053] like Figure 3As shown, the movable plate 320 has a second edge 321 facing the first edge 312. Specifically, for the left movable plate 320, the second edge 321 is located on the right side of the movable plate 320. For the right movable plate 320, the second edge 321 is located on the left side of the movable plate 320.

[0054] like Figure 3 As shown, a second nut positioning groove 3211 is formed on the upper surface of the second edge 321. The number of second nut positioning grooves 3211 can be one or more, and in particular, the number of second nut positioning grooves 3211 on the second edge 321 can match the number of first nut positioning grooves 3121 on the corresponding first edge 312. For example, when there are two first nut positioning grooves 3121 on the first edge 312, there are also two second nut positioning grooves 3211 on the second edge 321.

[0055] like Figure 3 As shown, the second nut positioning groove 3211 has a second opening 3212 on the side facing the first edge 312. Specifically, for the left movable plate 320, the second opening 3212 of the second nut positioning groove 3211 is located on the right side. For the right movable plate 320, the second opening 3212 of the second nut positioning groove 3211 is located on the left side. Thus, for the left movable plate 320 and the left first edge 312 of the part support plate 310, the first opening 3122 and the second opening 3212 are arranged opposite to each other.

[0056] like Figure 3 As shown, the first drive assembly 330 is connected to the movable plate 320 to drive the movable plate 320 to move between the relaxed position and the clamped position.

[0057] like Figure 3 and Figure 5 As shown, when the movable plate 320 is in the clamping position, the distance between the first opening 3122 and the second opening 3212 is the first distance, so that the first nut positioning groove 3121 and the second nut positioning groove 3211 together clamp the nut 140.

[0058] Specifically, in this embodiment, the first nut positioning groove 3121 and the second nut positioning groove 3211 are both half a regular hexagon. Therefore, when the moving plate 320 is in the clamping position, the first distance is zero, and the first nut positioning groove 3121 and the second nut positioning groove 3211 together form a complete regular hexagon. However, when one of the first nut positioning groove 3121 and the second nut positioning groove 3211 is smaller than half a regular hexagon, the first distance can be greater than zero.

[0059] like Figure 4 and Figure 6As shown, when the movable plate 320 is in the relaxed position, the distance between the first opening 3122 and the second opening 3212 is a second distance greater than the first distance, so that the second nut positioning groove 3211 is separated from the nut 140.

[0060] As an example of the first drive assembly 330, the first drive assembly 330 can be a cylinder, with the piston rod of the cylinder connected to the movable plate 320, thereby driving the movable plate 320 to reciprocate linearly. However, the first drive assembly 330 can also be other structures, as long as it can drive the movable plate 320 to move between the relaxed position and the clamped position.

[0061] In summary, the nut positioning and installation device of this application realizes the clamping and loosening of the nut 140 by setting a first nut positioning groove 3121 and a second nut positioning groove 3211 that can move closer or further apart from each other. When the nut 140 needs to be positioned, the first nut positioning groove 3121 and the second nut positioning groove 3211 clamp the nut 140. When the nut 140 needs to be removed, the first nut positioning groove 3121 and the second nut positioning groove 3211 loosen the nut 140, thereby solving the problem that the nut 140 is easily stuck in the positioning groove.

[0062] like Figure 3 As shown, the positioning assembly 300 may further include a mounting plate 340, which is fixedly disposed on the upper surface of the first substrate 200. The part support plate 310 and the movable plate 320 are located on the upper surface of the mounting plate 340. The first drive assembly 330 is fixedly disposed on the first substrate 200, and the piston rod of the first drive assembly 330 is located above the mounting plate 340. Thus, the first drive assembly 330 drives the movable plate 320 to move on the mounting plate 340.

[0063] like Figure 3 As shown, the nut positioning and mounting device may further include a first guide rod 350, which is fixedly disposed relative to the part support plate 310. Specifically, one end of the first guide rod 350 can be fixedly disposed on the mounting plate 340 via a fixing seat 360, and the other end of the first guide rod 350 is located on the part support plate 310. A movable plate 320 passes through the first guide rod 350, thereby being able to move on the first guide rod 350. The first guide rod 350 guides the movement of the movable plate 320. Furthermore, as an example, each movable plate 320 is provided with two first guide rods 350.

[0064] like Figure 3As shown, a part limiting part 322 is provided on the upper surface of the movable plate 320. When the movable plate 320 is in the clamping position, the part limiting part 322 and the part support surface 311 together form a part limiting groove. Specifically, in this embodiment, the shape of the part limiting part 322 can be adapted to the shape of the lower end of the pump body 110, so that when the movable plate 320 is in the clamping position, the part limiting plate can limit and clamp the lower end of the pump body 110.

[0065] like Figure 2 As shown, the nut positioning and mounting device also includes a second base plate 400, and the first base plate 200 and the second base plate 400 are slidably connected by a horizontal slide rail. Thus, the position of the positioning component 300 can be adjusted in the horizontal direction to facilitate the placement of the pump body 110 and the motor 120 onto the positioning component 300. In particular, when the lifting platform 500 (described later) is present, by moving the first base plate 200, the positioning component 300 can be misaligned with the lifting platform 500 to facilitate the placement of the pump body 110 and the motor 120 onto the positioning component 300.

[0066] In addition, a positioning block (not shown) may be provided on the second substrate 400. The positioning block is used to position the first substrate 200. For example, when the first substrate 200 abuts against the positioning block, the positioning component 300 is located below the lifting platform 500 and aligned with the lifting platform 500.

[0067] like Figure 2 As shown, the nut positioning and mounting device also includes a lifting platform 500, a part clamping plate 600, and a second drive assembly 700. The lifting platform 500 is located above the part support surface 311 and is height-adjustable relative to the part support surface 311. The part clamping plate 600 is disposed on the lower surface of the lifting platform 500. The second drive assembly 700 is connected to the lifting platform 500, allowing the lifting platform 500 to have a downward pressing position and an upward lifting position. When the lifting platform 500 is in the downward pressing position, the part clamping plate 600 presses the part downward against the part support surface 311. When the lifting platform 500 is in the upward lifting position, the part clamping plate 600 separates from the part. Therefore, by providing a height-adjustable lifting platform 500, the part clamping plate 600 can be used to press or loosen the part, facilitating the tightening of the bolt 130.

[0068] like Figure 2 As shown, the lifting platform 500 has a through hole 510 extending vertically. The part clamping plate 600 is disposed around the through hole 510. When the lifting platform 500 is in the pressed-down position, the hole on the part is located inside the through hole 510, so that the bolt 130 can be inserted into the part through the through hole 510 and tightened in the through hole 510. For example, a screwdriver can be connected to the nut 132 of the bolt 130 through the through hole 510, and then the bolt 130 can be tightened using the screwdriver.

[0069] like Figure 2 As shown, a second guide rod 800 extending longitudinally is provided on the lifting platform 500, the lower end of the second guide rod 800 passes through the second base plate 400, and the second drive assembly 700 is fixedly disposed on the second base plate 400.

[0070] like Figure 7 and Figure 8 As shown, the part clamping plate 600 is provided with a bolt positioning groove 610. For example... Figure 9 As shown, the bolt positioning groove 610 is aligned with the first nut positioning groove 3121, so that when the lifting platform 500 is in the pressed position, the bolt positioning groove 610 is aligned with the hole on the part.

[0071] like Figure 7 and Figure 8 As shown, the part clamping plate 600 includes a bolt limiting ring 620 and a part clamping part 630. The bolt limiting ring 620 is disposed on the lower surface of the lifting platform 500, and the bolt positioning groove 610 is located on the bolt limiting ring 620. The part clamping part 630 is disposed on the lower surface of the bolt limiting ring 620.

[0072] like Figure 10 As shown, when the moving plate 320 is in the clamping position and the lifting platform 500 is in the pressing position, the part limiting part 322 is clamped to the side of the lower end of the pump body 110, and the part pressing part 630 presses downward against the upper surface of the motor 120, thereby fixing the pump body 110 and the motor 120 to each other. Furthermore, as... Figure 10 As shown, bolt 130 can pass through the bolt positioning groove 610, through the motor 120 and the pump body 110, and then be connected to nut 140, thereby connecting bolt 130 and nut 140.

[0073] After the bolts 130 and nuts 140 are connected, the lifting platform 500 can be moved upward to the raised position, and the moving plate 320 can be moved outward to the relaxed position, so that the assembled pump 100 can be removed from the parts support plate 310.

[0074] Although this application has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this application fall within the scope of protection claimed in this application.
