[0003] When using existing automatic screw fastening machines, their function is to improve production efficiency, ensure product quality, reduce labor costs, and enhance safety. However, existing automatic screw fastening machines cannot easily disassemble and assemble the placement plate. When screwing workpieces of different sizes, the placement plate cannot provide stable support, which affects processing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic screw fastening machine that is easy to assemble, so as to solve the problem mentioned in the background art that the existing automatic screw fastening machines cannot easily disassemble and assemble the placement plate, and the placement plate cannot stably support the workpieces of different sizes when screwing them, which affects the processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic screw fastening machine that is easy to assemble, comprising:

[0006] The device body includes a device body, with support frames connected to both sides of the surface of the device body, and a placement plate provided at the top of the support frames;

[0007] An assembly structure is connected to one side of the inner surface of the support frame. The assembly structure includes a hydraulic rod, one end of which is connected to a slider. A first bearing is connected inside the top of the slider, and a fixing screw is connected to the top of the first bearing. An installation sleeve is fitted onto the outer wall of the top of the slider, and sliding rods are inserted inside both sides of the installation sleeve.

[0008] Preferably, the slider is inserted into the support frame and slidably connected to the support frame. A groove is formed on the top surface of the slider. The bottom end of the first bearing is connected to one side of the inner wall of the groove formed on the slider. The slider and the fixing screw are movably connected by the first bearing.

[0009] Preferably, the mounting sleeve is connected to the bottom surface of the placement plate, the bottom surface of the mounting sleeve has a through hole, the bottom surface of the placement plate has a threaded groove, and the top end of the fixing screw passes through the through hole of the mounting sleeve and is rotatably connected to the inside of the threaded groove of the placement plate.

[0010] Preferably, the slide rods are configured as two sets and respectively connected to the two sides of the slider. The mounting sleeve has positioning grooves on both sides, and one end of the slide rod is inserted into the positioning groove of the mounting sleeve.

[0011] Preferably, the top of the placement plate is rotatably connected to a limiting structure, the limiting structure including a limiting screw, the bottom end of the limiting screw being connected to a second bearing, the bottom end of the second bearing being connected to a positioning rod, and limiting blocks being connected to both sides of the positioning rod.

[0012] Preferably, the limiting screw and the positioning rod are movably connected by a second bearing, and a threaded hole is provided on one side of the inner wall of the threaded groove of the placement plate, and the limiting screw is rotatably connected to the inside of the threaded hole of the placement plate.

[0013] Preferably, a limiting groove is formed on the top surface of the fixing screw, and the positioning rod and the limiting block are inserted into the limiting groove formed on the fixing screw. The positioning rod and the limiting block can be inserted into the limiting groove formed on the fixing screw through the threaded hole formed on the placement plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By moving the placement plate towards the top of the slider, the fixing screw is inserted into the through hole of the mounting sleeve, allowing the fixing screw to rotate and connect to the threaded groove of the placement plate. The first bearing ensures that the rotation of the fixing screw does not affect the angle of the slider, and the mounting sleeve is fitted onto the outer wall of the top of the slider. The sliding rods connected to both sides of the slider are inserted into the positioning groove of the mounting sleeve, limiting the angle between the placement plate and the slider. This achieves a quick assembly effect between the support frame and the placement plate. The slider can be moved within the support frame using a hydraulic rod. When disassembling the placement plate, it can be directly pulled upwards for quick disassembly, avoiding the problem of not being able to stably support workpieces of different sizes due to the inability to replace the placement plate, which would affect processing efficiency.

[0016] 2. By moving the positioning rod and the limiting block through the threaded hole at the top of the placement plate into the limiting groove of the fixing screw, the limiting screw can move vertically downwards. Then, the angle of the limiting screw is rotated so that the limiting screw is rotatably connected to the threaded hole in the placement plate. The second bearing is used to ensure that the rotation of the limiting screw does not affect the angle of the positioning rod, and the limiting screw limits the positioning rod, thereby restricting the fixing screw and preventing the placement plate from detaching from the fixing screw.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] An easy-to-assemble automatic screw fastening machine includes:

[0026] The device body 1 includes a device body 11. Support frames 12 are connected to both sides of the surface of the device body 11. A placement plate 13 is provided at the top of the support frame 12. The internal material of the placement plate 13 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application. Therefore, no further details are made.

[0027] An assembly structure 2 is connected to one side of the inner surface of the support frame 12. The assembly structure 2 includes a hydraulic rod 21. One end of the hydraulic rod 21 is connected to a slider 22. The top of the slider 22 is connected to a first bearing 23. The top of the first bearing 23 is connected to a fixing screw 24. An installation sleeve 25 is sleeved on the outer wall of the top of the slider 22. Slide rods 26 are inserted inside both sides of the installation sleeve 25.

[0028] Furthermore, the slider 22 is inserted into the support frame 12 and slidably connected to the support frame 12. A groove is opened on the top surface of the slider 22. The bottom end of the first bearing 23 is connected to one side of the inner wall of the groove opened in the slider 22. The slider 22 and the fixing screw 24 are movably connected by the first bearing 23, so that the angle of the slider 22 is not affected when the fixing screw 24 is rotated by the first bearing 23.

[0029] Furthermore, the mounting sleeve 25 is connected to the bottom surface of the placement plate 13. The bottom surface of the mounting sleeve 25 has a through hole, and the bottom surface of the placement plate 13 has a threaded groove. The top end of the fixing screw 24 passes through the through hole of the mounting sleeve 25 and is rotatably connected to the inside of the threaded groove of the placement plate 13. This allows the fixing screw 24 to connect and fix the slider 22 and the placement plate 13, thereby enabling quick assembly of the support frame 12 and the placement plate 13.

[0030] Furthermore, the slide rods 26 are configured as two sets and are respectively connected to the two sides of the slide block 22. The mounting sleeve 25 has positioning grooves on both sides, and one end of the slide rod 26 is inserted into the positioning groove of the mounting sleeve 25.

[0031] Furthermore, a limiting structure 3 is rotatably connected inside the top of the placement plate 13. The limiting structure 3 includes a limiting screw 31, a second bearing 32 connected to the bottom end of the limiting screw 31, a positioning rod 33 connected to the bottom end of the second bearing 32, and limiting blocks 34 connected to both sides of the positioning rod 33. This allows the limiting screw 31 to restrict the fixing screw 24, preventing the placement plate 13 from detaching from the fixing screw 24.

[0032] Furthermore, the limiting screw 31 and the positioning rod 33 are movably connected by the second bearing 32. A threaded hole is provided on one side of the inner wall of the threaded groove of the placement plate 13. The limiting screw 31 is rotatably connected to the inside of the threaded hole of the placement plate 13, so that the limiting screw 31 is limited by the threaded hole of the placement plate 13, and the positioning rod 33 and the limiting block 34 are limited by the limiting screw 31.

[0033] Furthermore, a limiting groove is formed on the top surface of the fixing screw 24. The positioning rod 33 and the limiting block 34 are inserted into the limiting groove formed on the fixing screw 24. The positioning rod 33 and the limiting block 34 can be inserted into the limiting groove formed on the fixing screw 24 through the threaded hole formed on the placement plate 13, so as to position the positioning rod 33 and the limiting block 34 through the limiting groove formed on the fixing screw 24, and use the two to make the limiting screw 31 move vertically downward.

[0034] Working principle: When assembling the automatic screw fastening machine, the placement plate 13 is moved towards the top of the slider 22, causing the fixing screw 24 to be inserted into the through hole of the mounting sleeve 25. This allows the fixing screw 24 to be rotatably connected to the threaded groove of the placement plate 13. The first bearing 23 ensures that the rotation of the fixing screw 24 does not affect the angle of the slider 22. The mounting sleeve 25 is fitted onto the outer wall of the top of the slider 22, and the sliding rods 26 connected to both sides of the slider 22 are inserted into the positioning grooves of the mounting sleeve 25, thus limiting the angle between the placement plate 13 and the slider 22. This achieves a quick assembly effect between the support frame 12 and the placement plate 13. The hydraulic rod 21 can be used to control the movement of the slider 22 inside the support frame 12. When disassembling the placement plate 13, it can be directly pulled upwards for quick disassembly.

[0035] When limiting the automatic screw fastening machine that is easy to assemble, the positioning rod 33 and the limiting block 34 are moved through the threaded hole at the top of the placement plate 13 into the limiting groove of the fixing screw 24, so that the limiting screw 31 can move vertically downward. Then, the angle of the limiting screw 31 is rotated so that the limiting screw 31 is rotatably connected to the threaded hole of the placement plate 13. The second bearing 32 is used to ensure that the rotation of the limiting screw 31 does not affect the angle of the positioning rod 33, and the limiting screw 31 limits the positioning rod 33, thereby restricting the fixing screw 24 by the limiting screw 31, so that the placement plate 13 cannot be separated from the fixing screw 24.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
