Description

Technical Field

[0001] The invention relates to the technical field of tailless wire thread insert processing, in particular to an automatic assembly device and an assembly method for a tailless wire thread insert. Background Art

[0002] On some substrates with relatively soft or low strength materials (such as aluminum alloys, magnesium alloys, etc.), directly processed threads are easily damaged when subjected to large axial forces or torques. The elasticity and high strength of the tailless wire screw can effectively disperse these forces and enhance the load-bearing capacity of the threaded connection. For example, in the field of aerospace, some aluminum alloy parts on aircraft use tailless wire screw sleeves to install various equipment, which can significantly improve the connection strength and ensure the safety and reliability of the equipment during flight.

[0003] Compared with manual assembly, the automatic assembly device can quickly install the tailless wire thread insert into the corresponding threaded hole. It can complete a large number of assembly tasks in a short time, greatly improving the production speed. For example, in the automobile manufacturing production line, a large number of thread inserts need to be installed on many parts such as engine cylinders and chassis. The automatic assembly device can complete the installation of multiple thread inserts per minute, which is incomparable to manual assembly. Although the automatic assembly device can be adjusted to a certain extent through programming and other methods, its flexibility is not as good as manual assembly when facing the production needs of small batches and multiple varieties.

[0004] In the patent document with the publication number CN221696753U, a semi-automatic assembly device for tailless wire screw inserts is disclosed. A linear guide is provided on one side of the base plate surface. A screwdriver holder that slides axially along the linear guide is slidably matched on the linear guide rail and is used to clamp an electric screwdriver. The tool head of the electric screwdriver is located outside the screwdriver holder and is coaxially arranged with the linear guide. A rotating tray that is coaxially arranged with the linear guide and is used to limit and clamp the workpiece is rotatably installed on the other side of the base plate surface. The rotating tray can ensure the accurate and stable movement of the assembly tool during the assembly process of the tailless wire screw insert, and can also realize the semi-automatic assembly of the tailless wire screw insert, which not only ensures the qualified rate of the assembly of the tailless wire screw insert, but also improves the assembly efficiency of the tailless wire screw insert.

[0005] When the above devices are in use, different specifications of tailless wire screw inserts and parts to be assembled may have differences in size, shape, etc. The automatic assembly device may not be able to adapt well to all types of screw inserts and parts, and some components need to be adjusted or replaced to match, resulting in poor working efficiency of the overall device and high cost for tailless wire screw inserts of different sizes.

[0006] Therefore, the present application proposes an automatic assembly device and an assembly method for a tailless wire thread insert. Summary of the invention

[0007] The purpose of the present invention is to solve the problem that there are different specifications of tailless wire screw inserts and parts to be assembled in the background technology, which may have differences in size, shape, etc. The automatic assembly device may not be able to adapt to all types of screw inserts and parts well, and some components need to be adjusted or replaced to match them.

[0014] Optionally, the assembly workpiece transmission component includes a workpiece placement slider slidably installed inside the X-axis transmission tube, the Y-axis rotation of the workpiece placement slider is equipped with a second bidirectional threaded rod, and the X-axis rotation of the workpiece placement slider is equipped with a first bidirectional threaded rod.

[0015] Optionally, two second supporting sliders are installed on the outer thread of the first bidirectional threaded rod, and two first supporting sliders are installed on the outer thread of the second bidirectional threaded rod. Four corner positioning blocks are installed in the internal sliding of the two first supporting sliders and the second supporting sliders.

[0016] Optionally, the clamping and positioning assembly includes an internal threaded block threadedly installed inside the Y-axis transmission tube, and a first electric telescopic rod is fixedly installed on one side of the internal threaded block.

[0019] On the other hand, the present application provides: a method for automatically assembling a tailless wire thread insert, comprising the following steps:

[0020] S1: The staff first places the installation workpiece on the extension plate, and uses the motor connected to the first bidirectional threaded rod and the second bidirectional threaded rod to drive the two to rotate along the X-axis and the Y-axis. The second support slider moves synchronously with the first support slider toward the installation workpiece position, and the four corners of the installation workpiece are positioned;

[0021] S2: The motor connected to the threaded positioning rod drives the threaded positioning rod to rotate, and the built-in thread block slides along the Y-axis according to the thread of the threaded positioning rod. The staff controls the built-in thread block to move to the same vertical line as the auxiliary positioning bracket according to the PLC program;

[0022] S3: The first electric telescopic rod extends to move the auxiliary support frame to the center of the tailless wire screw sleeve transmission chamber, and the second electric telescopic rod first telescopes the telescopic positioning frame along the connection of the auxiliary support frame, and the telescopic positioning frame locates the position of the tailless wire screw sleeve in the tailless wire screw sleeve transmission assembly through the visual system installed on the surface of the clamping positioning assembly, and moves with the threaded clamping block to the tailless wire screw sleeve located in the center of the protective positioning plate;

[0023] S4: The tailless wire screw insert pushing assembly pushes the tailless wire screw insert to move outward, and the motor drives the gear to rotate. The gear drives the gear built-in arc track block to rotate forward along the auxiliary positioning bracket through meshing with the gear built-in arc track block, and the gear built-in arc track block drives the hollow positioning rod to rotate synchronously through the connected limit plug block. Since the bottom of the hollow positioning rod is limited by another set of limit plug blocks and the transverse slide rail fixed by the transverse track plate, the hollow positioning rod moves along the transverse track plate toward the tailless wire screw insert, and the arc positioning block contacts and positions the tailless wire screw insert;

[0024] S5: The thread clamping block in a normal state first extends into the interior of the tailless wire screw sleeve, and the third electric telescopic rod then drives the limit plug-in block to move downward along the limit of the thread clamping block. As the limit plug-in block moves downward, the inclined rod inside the hollow positioning block deflects along the hollow positioning block and the thread clamping block, causing the thread clamping block to gradually expand outward along the limit positioning circular block. As the thread on the surface of the thread clamping block corresponds to the gap between the tailless wire screw sleeve, the limit positioning circular block can fully clamp the tailless wire screw sleeve;

[0025] S6: The built-in thread block and the first electric telescopic rod drive the tailless wire screw sleeve to slide along the X-axis and the Y-axis, and then move the tailless wire screw sleeve to the assembly workpiece. As the auxiliary motor drives the limit positioning round block, the thread clamping block and the limit plug-in block to rotate through the third electric telescopic rod, the tailless wire screw sleeve clamped by the thread clamping block is installed on the installation workpiece, and then the third electric telescopic rod returns to its original position upward, and the first electric telescopic rod and the built-in thread block drive the thread clamping block away from the installed tailless wire screw sleeve, and the S1-S5 operations are cyclically performed to install the tailless wire screw sleeve.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Through the arc-shaped positioning block and the tailless wire screw sleeve, the tailless wire screw sleeve of different diameters or shapes can be placed and transported, and the pressure sensing spring assembly can control the pressure of the arc-shaped positioning block through the rebound of the tailless wire screw sleeve. The pressure of the arc-shaped positioning block on the tailless wire screw sleeve makes the tailless wire screw sleeve always maintain the specified state during the process of being pushed outside, and will not tilt, which is convenient for the clamping assembly to clamp and transport it later;

[0028] 2. As the thread on the surface of the thread clamping block corresponds to the gap between the tailless wire screw sleeves, the limit positioning round block can fully clamp the tailless wire screw sleeves. Here, if the gap between the tailless wire screw sleeves is small, the external thread of the thread clamping block cannot be inserted. The limit plug-in block uses the surface to fully press the inside of the tailless wire screw sleeve, thereby clamping the tailless wire screw sleeve, especially for small tailless wire screw sleeves, which can be better positioned, so that tailless wire screw sleeves of different shapes can be better clamped, thereby improving work efficiency and reducing processing costs;

[0029] 3. The corresponding second supporting slider or the first supporting slider connected on both sides of the first bidirectional threaded rod or the second bidirectional threaded rod can move synchronously toward the installation workpiece position, and most of the installation workpieces are cubes or rectangular parallelepipeds. Therefore, after positioning the four corners of the installation workpiece, the stability of the installation workpiece is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0042] like Figure 1 - Figure 3As shown, an automatic assembly device for a tailless wire screw insert proposed by the present invention comprises a processing template component 1, a workpiece assembly transmission component 2 is slidably installed on one side of the processing template component 1, a clamping and positioning component 3 is slidably installed on the top of the processing template component 1, a tailless wire screw insert transmission component 4 is installed on one side of the processing template component 1, the processing template component 1 also comprises two X-axis transmission tubes 105 fixedly installed on the top of the support template 101, two positioning support frames 102 are fixedly installed on the top of the support template 101, a Y-axis transmission tube 103 is fixedly installed between the two positioning support frames 102, a threaded positioning rod 104 is rotatably installed inside the Y-axis transmission tube 103, the workpiece assembly transmission component 2 comprises a workpiece placement slider 201 slidably installed inside the X-axis transmission tube 105, a second bidirectional threaded rod 205 is rotatably installed on the Y-axis of the workpiece placement slider 201, a first bidirectional threaded rod 202 is rotatably installed on the X-axis of the workpiece placement slider 201, two second support sliders 206 are threadedly installed on the outer side of the first bidirectional threaded rod 202, and the second bidirectional threaded rod 20 5 is provided with two first supporting slide blocks 203 on the outer thread, and four corner positioning blocks 204 are slidably installed inside the two first supporting slide blocks 203 and the second supporting slide block 206. The first supporting slide block 203 is fixedly provided with an extension plate toward the center of the frame of the workpiece placement slide block 201, and the staff first places the installation workpiece on the extension plate, and uses the motor connected to the first bidirectional threaded rod 202 and the second bidirectional threaded rod 205 to drive the two to rotate along the X-axis and the Y-axis. In this process, according to the size of the installation workpiece, a plurality of corner positioning blocks 204 are fitted toward the corners of the installation workpiece. Since the threads on both sides of the first bidirectional threaded rod 202 and the second bidirectional threaded rod 205 are in positive and negative states, the corresponding second supporting slide blocks 206 or the first supporting slide block 203 connected to both sides of the first bidirectional threaded rod 202 or the second bidirectional threaded rod 205 can be synchronously moved toward the installation workpiece position, and most of the installation workpieces are cubes or cuboids. Therefore, after positioning the four corners of the installation workpiece, the stability of the installation workpiece is further improved.

[0043] If the installation workpiece is cylindrical, the corner positioning block 204 can be removed and replaced with a corner positioning block 204 with an arc-shaped built-in contact surface, so that installation workpieces of different shapes can be better positioned.

[0044] like Figure 1 - Fig.10As shown, the clamping and positioning assembly 3 includes an internal threaded block 301 threadedly installed inside the Y-axis transmission tube 103, a first electric telescopic rod 302 is fixedly installed on one side of the internal threaded block 301, an auxiliary support frame 303 is fixedly installed on the bottom of the first electric telescopic rod 302, a telescopic positioning frame 304 is fixedly installed on the bottom of the auxiliary support frame 303, a second electric telescopic rod 305 is fixedly installed on the bottom of the auxiliary support frame 303, the bottom of the second electric telescopic rod 305 is fixedly installed on one side of the telescopic positioning frame 304, a limited positioning circular block 306 is rotatably installed on the bottom of the telescopic positioning frame 304, a third electric telescopic rod 311 is installed on the bottom of the second electric telescopic rod 305 through an auxiliary motor, and the bottom of the third electric telescopic rod 311 A limited plug-in block 308 is fixedly installed on the outside of the limited plug-in block 308, and a plurality of hollow positioning blocks 310 are fixedly installed on the outside of the limited plug-in block 308. A plurality of tilting rods 309 are hinged on one side of the hollow positioning block 310. A threaded clamping block 307 is hinged on the side of the tilting rod 309 away from the limited plug-in block 308. The threaded clamping block 307 is slidably installed on the outside of the limited positioning round block 306. The limited positioning round block 306 is slidably installed on the outside of the third electric telescopic rod 311 through the card slot. When the motor connected to the threaded positioning rod 104 drives the threaded positioning rod 104 to rotate, the built-in threaded block 301 slides along the Y-axis according to the thread guide of the threaded positioning rod 104. First, the staff controls the built-in threaded block 301 to move to the auxiliary positioning rod according to the PLC program. The first electric telescopic rod 302 is then extended to move the auxiliary support frame 303 to the center of the tailless wire screw sleeve transmission chamber 405, and the second electric telescopic rod 305 first telescopically moves the telescopic positioning frame 304 along the connection of the auxiliary support frame 303, and the telescopic positioning frame 304 locates the position of the tailless wire screw sleeve in the tailless wire screw sleeve transmission assembly 4 through the visual system installed on the surface of the clamping positioning assembly 3, and moves with the threaded clamping block 307 to the tailless wire screw sleeve located in the center of the protective positioning plate 404, and the threaded clamping block 307 in a normal state first extends into the interior of the tailless wire screw sleeve, and the third electric telescopic rod 311 then drives the limiting plug-in block 308 to move along the threaded clamping block 307, the threaded clamping block 307 is limited by the limit positioning circular block 306, so that the limit positioning circular block 306 can only slide along the threaded clamping block 307. As the limit plug-in block 308 moves downward, the inclined rod 309 inside the hollow positioning block 310 deflects along the hollow positioning block 310 and the threaded clamping block 307, causing the threaded clamping block 307 to gradually expand outward along the limit positioning circular block 306. As the surface threads of the threaded clamping block 307 correspond to the gaps between the tailless wire screw sleeves, the limit positioning circular block 306 can fully clamp the tailless wire screw sleeves. It is explained here that if the gaps between the tailless wire screw sleeves are small, they cannot be inserted by the external threads of the threaded clamping block 307.The limiting plug block 308 uses the surface to exert sufficient pressure on the inside of the tailless wire screw sleeve, thereby clamping the tailless wire screw sleeve, especially for small tailless wire screw sleeves, which can better position the tailless wire screw sleeves, so that tailless wire screw sleeves of different shapes can be better clamped, thereby improving work efficiency and reducing processing costs;

[0045] The built-in threaded block 301 and the first electric telescopic rod 302 drive the tailless wire screw sleeve to slide along the X-axis and the Y-axis, and then move the tailless wire screw sleeve to the assembly workpiece. As the auxiliary motor drives the limit positioning round block 306, the thread clamping block 307 and the limit plug-in block 308 to rotate through the third electric telescopic rod 311, the tailless wire screw sleeve clamped by the thread clamping block 307 is installed on the installation workpiece, and then the third electric telescopic rod 311 is restored upward, and the first electric telescopic rod 302 and the built-in threaded block 301 drive the thread clamping block 307 to move away from the installed tailless wire screw sleeve, and the cyclic operation is performed to install the tailless wire screw sleeve.

[0046] like Figure 1 - Figure 8 As shown, the processing template component 1 includes a supporting template 101, and the tailless wire screw transmission component 4 includes a gear 402 fixedly installed at the bottom of the supporting template 101, an auxiliary positioning bracket 401 is fixedly installed on the side of the supporting template 101 away from the gear 402, and a gear built-in arc track block 403 is rotatably installed inside the auxiliary positioning bracket 401, and a transverse track plate 408 is fixedly installed inside the auxiliary positioning bracket 401, and a group of limiting plugs 409 are slidably installed on the outer side of the transverse track plate 408 through a transverse slide rail, and a hollow positioning rod 406 is fixedly installed on one side of the limiting plug 409, and the number of the limiting plugs 409 is two groups, and the other group of limiting plugs 409 is slidably installed in the arc slide rail of the gear built-in arc track block 403, and the two groups of limiting plugs 409 are arranged in a ring state with respect to the surface of the gear built-in arc track block 403 and the transverse track plate 408;

[0047] The outer side of the gear-tooth built-in arc track block 403 is meshedly connected with a gear 402, and the gear 402 is arranged on one side of the supporting template 101. A movable push rod 410 is slidably installed inside the hollow positioning rod 406, and a pressure sensing spring assembly 407 is fixedly installed between the movable push rod 410 and the hollow positioning rod 406. An arc positioning block 411 is fixedly installed on the side of the movable push rod 410 away from the pressure sensing spring assembly 407. When the staff needs to transmit the tailless wire screw sleeve, the tailless wire screw sleeve pushing assembly 412 pushes the tailless wire screw sleeve to move outward, and the motor drives the gear 402 to rotate. The gear 402 drives the gear-tooth built-in arc track block 403 to rotate forward along the auxiliary positioning bracket 401 through meshing with the gear-tooth built-in arc track block 403, and the gear-tooth built-in arc track block 40 The hollow positioning rod 406 is driven to rotate synchronously by the connected limiting plug 409. Since the bottom of the hollow positioning rod 406 is limited by another set of limiting plugs 409 and the transverse slide rail fixed by the transverse track plate 408, the hollow positioning rod 406 moves toward the tailless steel screw sleeve along the transverse track plate 408, and the arc positioning block 411 contacts the tailless steel screw sleeve, and can be placed and transported according to tailless steel screw sleeves of different diameters or shapes. The pressure sensing spring assembly 407 can control the pressure of the arc positioning block 411 on the tailless steel screw sleeve through the rebound of the tailless steel screw sleeve, so that the tailless steel screw sleeve always maintains a specified state during the process of being pushed outward, and will not tilt, which is convenient for the clamping assembly to clamp and transport it later.

[0048] In this embodiment, a tailless wire screw sleeve transmission chamber 405 is opened inside the transverse track plate 408 and the gear built-in arc track block 403, and a plurality of protective positioning plates 404 are arranged on the top of the gear built-in arc track block 403. The plurality of protective positioning plates 404 are in a closed state with the tailless wire screw sleeve transmission chamber 405 under normal conditions to prevent dust from interfering with the installation of the tailless wire screw sleeve. When the tailless wire screw sleeve needs to be installed or placed, the protective positioning plates 404 are opened by program operation, thereby facilitating the input or output of the tailless wire screw sleeve.

[0049] Furthermore, the degree of deflection of the protective positioning plate 404 along the gear tooth built-in arc track block 403 can be controlled, so that when the tailless wire screw sleeve is clamped by the threaded clamping block 307, the gear tooth built-in arc track block 403 rotates in the opposite direction, causing the friction pattern inside the protective positioning plate 404 and the tailless wire screw sleeve to generate rotational friction, thereby fully rubbing the burrs and other objects that may exist on the outside of the tailless wire screw sleeve, thereby improving the stability and accuracy of the installation between the tailless wire screw sleeve and the installation workpiece.

[0050] On the other hand, the present application provides: a method for automatically assembling a tailless wire thread insert, comprising the following steps:

[0051] S1: The staff first places the installation workpiece on the extension plate, and uses the motor connected to the first bidirectional threaded rod 202 and the second bidirectional threaded rod 205 to drive the two to rotate along the X-axis and the Y-axis. The second support slider 206 and the first support slider 203 move synchronously toward the installation workpiece position, and the four corners of the installation workpiece are positioned;

[0052] S2: The motor connected to the threaded positioning rod 104 drives the threaded positioning rod 104 to rotate, and the built-in thread block 301 slides along the Y axis according to the thread guide of the threaded positioning rod 104. The staff controls the built-in thread block 301 to move to the same vertical line as the auxiliary positioning bracket 401 according to the PLC program;

[0053] S3: The first electric telescopic rod 302 is extended to move the auxiliary support frame 303 to the center of the tailless wire screw sleeve transmission chamber 405, and the second electric telescopic rod 305 first telescopes the telescopic positioning frame 304 along the connection of the auxiliary support frame 303, and the telescopic positioning frame 304 locates the position of the tailless wire screw sleeve in the tailless wire screw sleeve transmission component 4 through the visual system installed on the surface of the clamping positioning component 3, and moves with the threaded clamping block 307 to the tailless wire screw sleeve located in the center of the protective positioning plate 404;

[0054] S4: The tailless wire screw insert pushing assembly 412 pushes the tailless wire screw insert to move outward, and the motor drives the gear 402 to rotate, and the gear 402 drives the gear built-in arc track block 403 to rotate forward along the auxiliary positioning bracket 401 through the engagement with the gear built-in arc track block 403, and the gear built-in arc track block 403 drives the hollow positioning rod 406 to rotate synchronously through the connected limiting plug block 409, because the bottom of the hollow positioning rod 406 is limited by another set of limiting plug blocks 409 and the transverse slide rail fixed by the transverse track plate 408, the hollow positioning rod 406 moves along the transverse track plate 408 toward the tailless wire screw insert, and the arc positioning block 411 contacts and positions the tailless wire screw insert;

[0055] S5: The threaded clamping block 307 in a normal state first extends into the interior of the tailless wire screw sleeve, and the third electric telescopic rod 311 then drives the limit plug-in block 308 to move downward along the limit of the threaded clamping block 307. As the limit plug-in block 308 moves downward, the inclined rod 309 inside the hollow positioning block 310 deflects along the hollow positioning block 310 and the threaded clamping block 307, causing the threaded clamping block 307 to gradually expand outward along the limit positioning circular block 306. As the surface threads of the threaded clamping block 307 correspond to the gap between the tailless wire screw sleeves, the limit positioning circular block 306 can fully clamp the tailless wire screw sleeves.

[0056] S6: The built-in threaded block 301 and the first electric telescopic rod 302 drive the tailless wire screw sleeve to slide along the X-axis and the Y-axis, and then move the tailless wire screw sleeve to the assembly workpiece. As the auxiliary motor drives the limit positioning round block 306, the thread clamping block 307 and the limit plug-in block 308 to rotate through the third electric telescopic rod 311, the tailless wire screw sleeve clamped by the thread clamping block 307 is installed on the installation workpiece, and then the third electric telescopic rod 311 returns to its original position upward, and the first electric telescopic rod 302 and the built-in threaded block 301 drive the thread clamping block 307 to move away from the installed tailless wire screw sleeve, and the S1-S5 operations are repeated to install the tailless wire screw sleeve.

8. An automatic assembly method for a tailless wire thread insert, applied to the automatic assembly device for a tailless wire thread insert according to claim 7, characterized in that: The following steps are involved: S1: The staff first places the installation workpiece on the extension plate, and uses the motor connected to the first bidirectional threaded rod (202) and the second bidirectional threaded rod (205) to drive the two to rotate along the X-axis and the Y-axis, and the second support slider (206) and the first support slider (203) move synchronously toward the installation workpiece position, and after positioning the four corners of the installation workpiece; S2: The motor connected to the threaded positioning rod (104) drives the threaded positioning rod (104) to rotate, and the built-in thread block (301) slides along the Y axis according to the thread of the threaded positioning rod (104). The staff controls the built-in thread block (301) to move to the same vertical line as the auxiliary positioning bracket (401) according to the PLC program; S3: The first electric telescopic rod (302) is extended to move the auxiliary support frame (303) to the center of the tailless wire screw sleeve transmission chamber (405), and the second electric telescopic rod (305) first moves the telescopic positioning frame (304) along the connection of the auxiliary support frame (303) to telescope, and the telescopic positioning frame (304) locates the position of the tailless wire screw sleeve in the tailless wire screw sleeve transmission component (4) through the visual system installed on the surface of the clamping positioning component (3), and moves with the threaded clamping block (307) to the tailless wire screw sleeve located in the center of the protective positioning plate (404); S4: the tailless wire screw insert pushing assembly (412) pushes the tailless wire screw insert to move outward, and the motor drives the gear (402) to rotate, and the gear (402) drives the gear built-in arc track block (403) to rotate forward along the auxiliary positioning bracket (401) through meshing with the gear built-in arc track block (403), and the gear built-in arc track block (403) drives the hollow positioning rod (406) to rotate synchronously through the connected limiting plug block (409), because the bottom of the hollow positioning rod (406) is limited by another set of limiting plug blocks (409) and the transverse slide rail fixed by the transverse track plate (408), the hollow positioning rod (406) moves along the transverse track plate (408) toward the tailless wire screw insert, and the arc positioning block (411) contacts and positions the tailless wire screw insert; S5: The threaded clamping block (307) in a normal state first extends into the interior of the tailless wire screw sleeve, and the third electric telescopic rod (311) then drives the limit plug-in block (308) to move downward along the limit of the threaded clamping block (307). As the limit plug-in block (308) moves downward, the inclined rod (309) inside the hollow positioning block (310) deflects along the hollow positioning block (310) and the threaded clamping block (307), causing the threaded clamping block (307) to gradually expand outward along the limit positioning circular block (306). As the thread on the surface of the threaded clamping block (307) corresponds to the gap between the tailless wire screw sleeve, the limit positioning circular block (306) can fully clamp the tailless wire screw sleeve; S6: The built-in thread block (301) and the first electric telescopic rod (302) drive the tailless wire screw sleeve to slide along the X-axis and the Y-axis, thereby moving the tailless wire screw sleeve to the assembly workpiece. As the auxiliary motor drives the limit positioning round block (306), the thread clamping block (307) and the limit plug-in block (308) to rotate through the third electric telescopic rod (311), the tailless wire screw sleeve clamped by the thread clamping block (307) is installed on the installation workpiece. Then, the third electric telescopic rod (311) returns to its original position upward, and the first electric telescopic rod (302) and the built-in thread block (301) drive the thread clamping block (307) to move away from the installed tailless wire screw sleeve. The operations of S1-S5 are cyclically performed to install the tailless wire screw sleeve.
