Description

Technical Field

[0001] This utility model relates to the technical field of pin assembly machines, specifically a high-precision free-assembly pin assembly machine. Background Technology

[0002] A bolt is a security component used to prevent doors and windows from being opened from the outside. Modern door and window bolts are generally made of metal, while ancient door and window bolts were made of wood. A bolt usually consists of two parts: one part has a movable rod, and the other part is a bolt hole, also called the bolt "nose".

[0003] A search revealed Chinese patent publication number CN209440053U, which discloses an inverted platform short pin assembly fixture. The fixture includes a base and, along the axial direction of the base, a clamping assembly for holding the pin, a positioning assembly for positioning the nut, and a limiting assembly for limiting the pressure block. The clamping assembly is driven by a driving assembly, allowing the pin to pass through the nut and extend into the bolt hole of the pressure block. The base also includes a rotating assembly for driving the limiting assembly to rotate, thereby locking the pressure block and the pin together. The advantages of this invention are mainly reflected in its simple structure, reasonable design, fully automated processing, elimination of manual operation, reduced workload, and avoidance of yield rate variations due to varying operator forces.

[0004] However, when assembling the pins, the assembly machine requires placing the nuts and pins one by one before the assembly can proceed. This shortens the assembly speed and reduces the production efficiency of the device when placing subsequent parts after assembling one. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-precision free-assembly pin assembly machine, which solves the problem that when assembling pins, the nuts and pins need to be placed one by one before assembly can be carried out. As a result, after assembling one part, the subsequent parts are placed, which shortens the assembly speed and reduces the production efficiency of the device.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-precision free-assembly pin assembly machine, comprising a base and wedge blocks. The upper end of the base is fixedly connected to a support seat via a support column. The upper end of the support seat is rotatably connected to a rotating plate. An L-shaped plate is fixedly installed on the upper end of the support seat. A cylinder is fixedly installed on the upper end of the L-shaped plate. A connecting plate is provided below the L-shaped plate, and the output shaft of the cylinder is fixedly connected to the upper end of the connecting plate through the interior of the L-shaped plate. A placement tube is fixedly connected to the lower end of the connecting plate via a connecting rod. A pressure plate is slidably connected inside the placement tube, and multiple second tension springs are fixedly installed at equal intervals between the pressure plate and the connecting plate. The wedge blocks are symmetrically slidably connected to the interior of the side wall of the placement tube.

[0007] Preferably, U-shaped blocks are fixedly installed on both ends of the placement tube, and wedge blocks are located inside the U-shaped blocks. A first tensioning spring is fixedly installed between the wedge blocks and the side walls inside the U-shaped blocks, and the side walls inside the placement tube of the wedge blocks have rounded corners, so as to facilitate the pin after the nut is installed to move the nut downward.

[0008] Preferably, a reciprocating motor is fixedly installed at the bottom of the support base, and the output shaft of the reciprocating motor is fixedly connected to the bottom of the rotating plate through the interior of the support base. Multiple clamps are rotatably connected at equal intervals at the upper end of the rotating plate, and pins are clamped between the clamping blocks of the clamps. A rotary motor is fixedly installed at equal intervals inside the top surface of the rotating plate, and the output shaft of the rotary motor is fixedly connected to the bottom of the clamps through the interior of the rotating plate, thereby facilitating the rotation of the rotating plate and the clamps.

[0009] Preferably, a limiting rod is fixedly connected to the upper end of the connecting plate, and the upper end of the limiting rod extends through the interior of the L-shaped plate to the upper end of the L-shaped plate and is slidably connected to the interior of the L-shaped plate, thereby facilitating the placement of the nut.

[0010] Preferably, a fixed ring is fixedly sleeved on the lower end of the pin, and a movable ring is slidably sleeved on the upper end. A third tension spring is fixedly sleeved between the movable ring and the fixed ring, which facilitates the stability of the position of the installed third tension spring and prevents the third tension spring from getting stuck in the threaded groove in the side wall of the pin when using the pin.

[0011] This utility model provides a high-precision free-assembly pin assembly machine. It has the following beneficial effects:

[0012] 1. This high-precision free-splicing pin assembly machine, when using the high-precision free-splicing pin assembly machine, through the setting of a placement tube that can only move up and down, allows the nuts to be stacked and placed inside the placement tube. When installing the nuts, the nuts can be moved down one by one, eliminating the need to place the nuts one by one.

[0013] 2. This high-precision free-assembly pin assembly machine, through the cooperation between the set rotating plate and the clamp, can conveniently clamp multiple pins, so that after assembling one pin, the next pin can be assembled immediately, thus improving the efficiency of pin assembly.

[0020] 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.

[0021] Example 1

[0022] Please see Figure 1-5This utility model embodiment provides a high-precision free-assembly pin assembly machine. A fixed ring 19 is fixedly sleeved on the lower end of the pin 9, and a movable ring 14 is slidably sleeved on its upper end. A third tension spring 20 is fixedly sleeved between the movable ring 14 and the fixed ring 19. A reciprocating motor 6 is fixedly installed at the bottom of the support base 2, and the output shaft of the reciprocating motor 6 is fixedly connected to the bottom of the rotating plate 7 through the interior of the support base 2. Multiple clamps 8 are rotatably connected at equal intervals at the upper end of the rotating plate 7, and the clamping blocks of the clamps 8 respectively clamp the pin 9. A rotary motor 10 is fixedly installed at equal intervals inside the top surface of the rotating plate 7, and the output shaft of the rotary motor 10 is fixedly connected to the bottom of the clamps 8 through the interior of the rotating plate 7. A fixed ring is fixedly sleeved on the lower end of the pin 9. 19, and a moving ring 14 is slidably sleeved on the upper external end. A third tension spring 20 is fixedly sleeved between the moving ring 14 and the fixed ring 19. When assembling the pin 9, the pin 9 is first clamped by the clamp 8. Then the nuts are stacked and placed inside the placement tube 4. The nuts are clamped by the pressure plate 18 and the wedge block 11, which makes the position of the nuts stable. When a pin 9 moves to the bottom of the placement tube 4, the cylinder 5 is opened to make the placement tube 4 move downward. The upper end of the pin 9 can easily enter the interior of the placement tube 4 by squeezing the wedge blocks 11 on both sides, and then enter the interior of the nut. At the same time, the rotary motor 10 is turned on to make the clamp 8 at this position rotate, which can easily make the nut threaded onto the outside of the pin 9.

[0023] Example 2

[0024] To facilitate the limiting of the wedge block 11, in this embodiment, as follows: Figure 1-5 As shown, U-shaped blocks 12 are fixedly installed on both sides of the placement tube 4, and wedge blocks 11 are located inside the U-shaped blocks 12. A first tension spring 13 is fixedly installed between the wedge blocks 11 and the side walls inside the U-shaped blocks 12. The side walls of the wedge blocks 11 inside the placement tube 4 are rounded. After the pin 9 is connected to the nut, the cylinder 5 moves upward. Since the side walls of the wedge blocks 11 are rounded, the wedge blocks 11 can move to both sides under the downward pulling force of the pin 9, making it easy to remove the installed nut.

[0025] Example 3

[0026] To facilitate the placement of the nut inside the placement tube 4, in this embodiment, as follows: Figure 1-5As shown, the upper end of the connecting plate 16 is fixedly connected to the limiting rod 17, and the upper end of the limiting rod 17 extends through the interior of the L-shaped plate 3 to the upper end of the L-shaped plate 3 and is slidably connected to the interior of the L-shaped plate 3. When the nut is placed inside the placement tube 4, the limiting rod 17 is pulled upward, which allows the pressure plate 18 inside the placement tube 4 to move upward until the pressure plate 18 moves to the outside of the upper end of the placement tube 4, so that the nut can be easily put into the interior of the placement tube 4.

[0027] It should be noted that in this embodiment, when assembling the pins 9, the pins 9 are first clamped by the clamps 8, and then the nuts are stacked and placed inside the placement tube 4. The nuts are held securely by the clamping between the pressure plate 18 and the wedge blocks 11. When one pin 9 moves to the bottom of the placement tube 4, the cylinder 5 is opened, causing the placement tube 4 to move downwards. This allows the upper end of the pin 9 to easily enter the interior of the placement tube 4 by pressing against the wedge blocks 11 on both sides, and then into the interior of the nut. Simultaneously, the rotary motor 10 is turned on, causing the clamps at that position to... Rotating the device 8 allows the nut to be easily threaded onto the outside of the pin 9. After the pin 9 is connected to the nut, the cylinder 5 moves upward. Since the side walls of the wedge block 11 are all rounded, the wedge block 11 can be moved to both sides under the downward pulling force of the pin 9, making it easy to remove the installed nut. When the nut is placed inside the placement tube 4, pulling the limit rod 17 upward allows the pressure plate 18 inside the placement tube 4 to move upward until the pressure plate 18 moves to the outside of the upper end of the placement tube 4, making it easy to put the nut into the inside of the placement tube 4.
