Description

Technical Field

[0001] This utility model relates to the field of assembly fixtures, and in particular to a trachea assembly fixture. Background Technology

[0002] In the manufacturing processes of machinery, automobiles, and home appliances, it is often necessary to quickly and accurately assemble flexible air tubes or cables with rigid pipe fittings. Traditional air tube assembly methods rely heavily on manual operation, which presents significant efficiency bottlenecks and potential quality issues. During manual operation, operators need to hold the pipe fitting with one hand and insert the air tube with the other, which is not only laborious but also makes it difficult to ensure uniform insertion depth, easily leading to incomplete assembly or poor sealing. For situations requiring the simultaneous assembly of multiple air tubes or cables, the efficiency and consistency of manual assembly are even more difficult to guarantee, and the curvature is hard to control when bending wire harnesses, which is detrimental to product uniformity. To address these problems, some auxiliary assembly jigs have emerged in existing technologies. These jigs typically use fixed positioning blocks to install pipe fittings and have corresponding grooves for pre-positioning air tubes. However, these jigs often suffer from poor versatility and cannot flexibly adapt to the assembly requirements of pipe fittings with different spacing.

[0003] During assembly, the trachea is prone to accidentally detaching from its placement slot, requiring repeated adjustments by the operator, disrupting the workflow and affecting assembly efficiency. Furthermore, the method of securing the tube connector to the fixture is relatively simple, typically involving only a plug-in connection, which may lead to loosening under significant axial force, thus requiring improved stability. Therefore, this paper provides a trachea assembly fixture. Utility Model Content

[0004] The main purpose of this utility model is to provide a device for harvesting algae from the surface of freshwater in coal mining subsidence areas, so as to solve the problem in related technologies that it is difficult to harvest algae from the surface of freshwater.

[0005] To achieve the above objectives, according to one aspect of the present invention, a trachea assembly fixture is provided, including a base, an installation slot on one side of the upper surface of the base, and two sets of slide rail grooves on the other side of the upper surface of the base, with two slide rail grooves symmetrically arranged in each set. The fixture also includes: an installation part disposed at the installation slot; and a placement part, with several placement parts slidably disposed at the slide rail grooves, and the trachea and its matching wires placed between the installation part and the placement part.

[0006] Furthermore, a baffle is fixedly installed on one edge of the upper surface of the base, and a connecting groove is provided inside the base.

[0007] Furthermore, a lead screw is rotatably installed in the slide rail groove. One end of the lead screw passes through the slide rail groove and is located in the connecting groove. A sprocket is fixedly installed at one end of the lead screw. A chain is connected between the sprockets, and the sprockets mesh with the chain. The other end of one of the lead screws passes through the base and is exposed to the outside. A handwheel is fixedly installed at the other end of the lead screw.

[0008] Furthermore, two limiting grooves are symmetrically formed on the side wall of the mounting slot, and the limiting grooves are inclined upward.

[0009] Furthermore, the mounting part includes a positioning plug, which is inserted into the mounting slot. Two fixing blocks are symmetrically fixed on both sides of the upper surface of the positioning plug. One side of the fixing block is an arc-shaped structure. A second fixing block is fixedly installed in the middle of the upper surface of the positioning plug. The second fixing block is a semi-cylindrical structure.

[0010] Furthermore, the positioning plug has two symmetrically formed telescopic grooves on its sidewall. A through groove is formed on the upper surface of the telescopic groove. A limiting plug is slidably installed in the telescopic groove. A push spring is fixedly installed on one side of the limiting plug. The other end of the push spring is fixedly installed on the inner sidewall of the telescopic groove. One end of the limiting plug has an upwardly inclined angle. One end of the limiting plug is inserted into the limiting groove. A push block is fixedly installed on the upper surface of the limiting plug. The push block passes through the through groove and is exposed to the outside.

[0011] Furthermore, the placement part includes a placement block, the upper surface of which has a placement groove, and a lead screw nut is fixedly installed on the lower surface of the placement block. The lead screw nut is slidably installed in the slide rail groove. The lead screw nut is a T-shaped structure adapted to the slide rail groove, and the lead screw nut is threadedly engaged with the lead screw.

[0012] Furthermore, the placement groove has a downward-sloping angle at the opening, a shrinkage groove is provided on the side wall of the placement groove, a stop block is slidably installed in the shrinkage groove, a return spring is fixedly installed on one side of the stop block, the other end of the return spring is fixedly installed on the inner side wall of the shrinkage groove, a pull shaft is fixedly installed on one side of the stop block, one end of the pull shaft passes through the placement block and is exposed to the outside, and one end of the stop block has a downward-sloping angle.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a screw-rail mechanism driven synchronously by a sprocket and chain, and uniformly adjusted via a handwheel, allows for simultaneous control of the movement of multiple placement blocks. This enables the fixture to flexibly adapt to the assembly of air tubes of different specifications, greatly improving its versatility and adjustment efficiency, and solving the problems of poor versatility and cumbersome adjustment of existing fixtures. By setting a mounting part with an inclined limiting groove within the mounting slot, and cooperating with a limiting insert and its pushing spring, the positioning insert can be quickly locked and released. This structure automatically locks when the positioning insert is inserted, providing a stable holding force to prevent the tube connector from loosening during assembly, ensuring operational stability and reliability. An anti-dislodgement mechanism consisting of a return spring and a stop block is installed within the placement slot. In its natural state, the stop block partially protrudes from the placement slot, effectively preventing the air tube pre-placed in the slot from sliding out. When it is necessary to insert or remove the air tube, the stop block can be easily retracted by pulling the pull shaft, making operation very convenient. This design solves the problem of the trachea easily coming out accidentally during pre-placement and assembly, ensuring the continuity of the assembly process and further improving assembly efficiency.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] This embodiment provides a tracheal assembly fixture, including a base 1, such as... Figure 1 , Figure 2 As shown, a vertical baffle 13 is fixedly installed on one edge of the upper surface of the base 1. A mounting slot 12 is provided on the upper surface of the base 1 near the baffle 13. The mounting slot 12 is used to install the mounting part 2 of the fixed pipe connector. An upwardly inclined limiting groove 121 is provided on each of the two symmetrical side walls of the mounting slot 12. like Figure 3 As shown, on the opposite side of the mounting slot 12 on the upper surface of the base 1, two sets of slide rail grooves 11 are provided in parallel. Each set of slide rail grooves 11 consists of two symmetrically arranged grooves, preferably with a T-shaped cross-section. A connecting groove 14 is also provided inside the base 1, which is connected to one end of the two sets of slide rail grooves 11. A lead screw 111 is rotatably installed in each set of slide rail grooves 11. One end of the lead screw 111 extends through the slide rail groove 11 into the connecting groove 14, and a sprocket 113 is fixedly installed at this end. The two sprockets 113 are connected to each other by a chain 114 and achieve meshing transmission. The other end of one of the lead screws 111 passes through the side wall of the base 1 and is exposed to the outside, and a handwheel 112 is fixedly installed at this exposed end. By rotating the handwheel 112, one lead screw 111 can be driven to rotate, and then through the transmission of the sprocket 113 and the chain 114, the other lead screw 111 is driven to rotate synchronously. Also includes: Installation part 2, such as Figure 4 , Figure 5As shown, the mounting part 2 mainly includes a positioning block 21, the shape of which is adapted to the mounting slot 12 on the base 1 and can be inserted into it. Two first fixing blocks 22 are symmetrically fixed on both sides of the upper surface of the positioning block 21. One side of each of these first fixing blocks 22 is machined into an arc shape for fixing a pipe connector from both sides. A second fixing block 221 is also fixedly installed in the middle of the upper surface of the positioning block 21. This second fixing block 221 has a semi-cylindrical structure and cooperates with the two first fixing blocks 22 to form a stable pipe connector mounting position. To achieve quick locking and unlocking of the positioning block 21 in the mounting slot 12, a telescopic groove 211 is provided on each of the two symmetrical side walls of the positioning block 21. A through groove 212 is provided above each telescopic groove 211. A limiting block 23 is slidably installed in each telescopic groove 211. One end of the limiting insert 23 is machined with an upwardly inclined bevel. A push spring 232 is fixedly connected to its inner side (i.e., the side near the bottom wall of the telescopic groove 211), and the other end of the push spring 232 is fixed to the inner side wall of the telescopic groove 211. In its natural state, the elastic force of the push spring 232 pushes the limiting insert 23 outward, so that the beveled end can be inserted into the limiting groove 121 on the side wall of the mounting slot 12 of the base 1, thereby firmly locking the entire positioning insert 21 onto the base 1. A push block 231 is also fixedly installed on the upper surface of the limiting insert 23. The push block 231 passes upward through the through groove 212 and is exposed. When it is necessary to remove the mounting part 2, the operator only needs to press the two push blocks 231 inward at the same time to overcome the elastic force of the push spring 232 and make the limiting insert 23 exit from the limiting groove 121, so that the positioning insert 21 can be pulled out from the mounting slot 12. It also includes: a placement section 3, which mainly includes a placement block 31. For example... Figure 6 , Figure 7As shown, a lead screw nut 313 is fixedly installed on the lower surface of the placement block 31. The shape of the lead screw nut 313 is adapted to the slide rail groove 11, and it is also a T-shaped structure, so that it can slide along the slide rail groove 11 without coming out of the groove. The lead screw nut 313 and the lead screw 111 installed in the slide rail groove 11 form a threaded pair engagement. Therefore, when the handwheel 112 is turned to drive the two lead screws 111 to rotate synchronously, all the placement blocks 31 that are engaged with the lead screws 111 can move synchronously along the slide rail groove 11, thereby adjusting the distance between the two placement parts 3 to accommodate different air tube assemblies. A placement groove 311 is provided on the upper surface of the placement block 31. The placement groove 311 is used to pre-place the air tube or wire to be assembled. In order to facilitate the insertion of the air tube, a downward inclined angle is machined at the opening of the placement groove 311 as a guide. To prevent the trachea from accidentally dislodging from the placement slot 311 during pre-placement or adjustment, a contraction groove 312 is provided on the side wall of the placement slot 311. A stop block 32 is slidably installed inside the contraction groove 312, and one end of the stop block 32 is also machined with a downward inclined angle. A return spring 322 is fixedly connected to the inner side of the stop block 32, and the other end of the return spring 322 is fixed to the inner side wall of the contraction groove 312. Under the elastic force of the return spring 322, a part of the stop block 32 naturally protrudes into the contraction groove 312, forming a blockage. A pull shaft 321 is also fixedly connected to the stop block 32, and one end of the pull shaft 321 passes through the side wall of the placement block 31 and is exposed to the outside. When the assembled air tube needs to be removed from the placement slot 311, the operator pulls the pull shaft 321 outward, which will cause the stop block 32 to compress the reset spring 322 and retract into the shrinkage slot 312, making room. After the operation is completed, the pull shaft 321 is released, and the stop block 32 will reset under the action of the spring. When the air tube is placed into the placement slot 311, the air tube presses against the angle of the stop block 32, causing the stop block 32 to retract into the shrinkage slot 312. After the air tube is placed, the reset spring 322 pushes the stop block 32 to reset. The stop block 32 acts as a barrier to prevent the air tube from falling off during assembly.

[0018] In use, first, select the appropriate mounting part 2 according to the model of the pipe connector and insert it into the mounting slot 12 of the base 1 until it automatically locks. Place the air hose and matching cable together according to the curvature of fixing block 22 and fixing block 221, and then insert them into the slots. Next, turn the handwheel 112 to adjust the position of all the placement blocks 31 according to the different air hoses. Then, pull the pull shaft 321 on each placement block 31 outwards to place multiple air hoses into their corresponding placement slots 311, and release the pull shaft 321 so that the stop block 32 locks the air hose. After placement, use the auxiliary materials to fix the air hose and cable. After fixing, remove the product to complete the assembly.
