The two toothed blocks 130 are symmetrically arranged about the central axis of the central hole of the bushing baffle 13. A toothed block 130 is located at the midpoint between every two notches 131. The bushing 14 is cylindrical in shape. The bushing 14 has grooves 140 for the toothed blocks 130 of the bushing baffle 13 to be inserted. There are two grooves 140, each corresponding to a toothed block 130. The bushing baffle pressure head is used to fix the bushing baffle 13 and press the bushing baffle 13 onto the bushing 14. The diameter of the central hole of the bushing baffle 13 is the same as the diameter of the central hole of the bushing 14.

[0059] like Figure 1 As shown, optionally, the seat 10 includes a body 100 and a plug 101. A spring 12 is embedded in the body 100. The plug 101 is embedded in the body 100, and the plug 101 and the body 100 are detachably connected, with one end of the spring 12 abutting against the plug 101.

[0060] like Figure 1 As shown, the plug 101 and the body 100 are detachably connected, and one end of the spring 12 abuts against the plug 101, facilitating the installation of the spring 12 into the body 100. The body 100 is generally cylindrical and has a cylindrical receiving hole, in which the spring 12 is located. The plug 101 is a cylindrical thin plate. A circular hole is provided at the bottom end of the body 100, and the plug 101 is embedded in the circular hole and fixed with a cylindrical pin 102. The bottom end of the spring 12 abuts against the plug 101. The plug 101 is made of steel, such as alloy tool steel.

[0061] like Figure 4 As shown, optionally, the body 100 includes a first half 1000 and a second half 1001, which are detachably connected. A guide post 11 passes through and is limited by the first half 1000, and is embedded in the second half 1001. This arrangement facilitates the disassembly and cleaning of the body 100 and the guide post 11. The first half 1000 includes a first receiving hole 10000 for the guide post 11 to pass through.

[0062] like Figure 4 As shown, the bottom of the guide post 11 is provided with a flange 110, the diameter of which is larger than the diameter of the first receiving hole 10000 so that the first half 1000 can limit the flange 110 of the guide post 11. The second half 1001 is a column, and its height is greater than that of the first half 1000. The second half 1001 is detachably connected to the first half 1000 by bolts. The second half 1001 includes a second receiving hole 10010, in which a spring 12 is disposed. The flange 110 of the guide post 11 is embedded in the second receiving hole 10010. The diameter of the flange 110 is equal to the diameter of the second receiving hole 10010.

[0063] like Figure 5 As shown, optionally, the bushing baffle pressure head also includes an insert 15, which passes through the guide post 11 and is used to hold the toothed block 130 of the bushing baffle 13. With this configuration, the bushing baffle 13 can be further fixed by holding the toothed block 130 of the bushing baffle 13 with the insert 15, making the bushing baffle 13 more secure.

[0064] like Figure 4As shown, the insert 15 is made of steel. The insert 15 is a rectangular thin plate. The guide post 11 has a lateral elongated through-hole, and the insert 15 is embedded in and exposed within the elongated through-hole. The first receiving hole 10000 of the first half 1000 also has a groove for the insert 15 to pass through. The width of the insert 15 is equal to the distance between the teeth 130 of the bushing baffle 13. The insert 15 can be embedded in the groove 140 of the bushing 14 to guide the guide post 11. The thickness of the insert 15 is equal to the width of the groove 140.

[0065] like Figure 1 As shown, optionally, the bushing baffle pressure head also includes a clamping screw 16, which passes through the guide post 11 and abuts against the insert 15. This arrangement facilitates the disassembly and cleaning of the insert 15.

[0066] like Figure 1 As shown, a lateral threaded hole is provided on the guide post 11, and the central axis of the threaded hole is perpendicular to the central axis of the elongated through hole. For example, the central axis of the threaded hole is parallel to the X-axis. A fastening screw 16 is threaded into the threaded hole. There are two fastening screws 16 and two threaded holes. When the fastening screw 16 is screwed in, it abuts against the side of the insert 15. When the fastening screw 16 abuts against the insert 15, the entire fastening screw 16 is embedded in the threaded hole to prevent the fastening screw 16 from obstructing the vertical movement of the guide post 11.

[0067] like Figure 6 As shown, optionally, the bushing baffle press head also includes an adjusting block 17, which is detachably connected to the body 100 and is used for detachable connection with the pressing device. This configuration facilitates the removal, replacement, and cleaning of the bushing baffle press head from the pressing device.

[0068] Please also refer to Figure 1 and Figure 6 The adjusting block 17 and the body 100 are detachably connected by bolts. For example, the adjusting block 17 has a vertical (i.e., parallel to the Z-axis) countersunk hole, and one end of the bolt passes through the countersunk hole to connect the adjusting block 17 and the body 100. The adjusting block 17 is made of steel. The bottom of the adjusting block 17 and the body 100 are connected. The adjusting block 17 is a column with a through hole axially parallel to the axis of the guide post 11 (i.e., parallel to the Z-axis). The bolt passes through the through hole of the adjusting block 17 and is screwed into the bottom of the pressing device to detachably connect the adjusting block 17 and the pressing device.

[0069] Please also refer to Figure 7 and Figure 8Optionally, the body 100 includes a protrusion 10011, a plug 101 embedded in the protrusion 10011, and the protrusion 10011 embedded in the adjusting block 17. The protrusion 10011 is used to position the adjusting block 17. This arrangement allows the protrusion 10011 to both accommodate the plug 101 and position the adjusting block 17, achieving a dual function for the protrusion 10011 and making the structure of the bushing baffle pressure head more compact.

[0070] Please also refer to Figure 7 and Figure 8 The protrusion 10011 is fixed to the left side of the second half 1001 by welding or integral molding. The protrusion 10011 is cuboid in shape and includes a circular hole. The plug 101 is fitted into the circular hole of the protrusion 10011. The adjusting block 17 is provided with a square hole 170, and the protrusion 10011 is fitted into the square hole 170 of the adjusting block 17. The adjusting block 17 is positioned by the corresponding abutment of each side plane of the protrusion 10011 and each side plane of the square hole 170. The protrusion 10011 is provided with a vertical (i.e., parallel to the Z-axis) screw hole for detachable connection with the adjusting block 17 by bolts.

[0071] like Figure 9 As shown, optionally, the bushing baffle press head also includes a magnet 18, which is fixed to the base 10 and used to attract the bushing baffle 13. The magnet 18 allows the bushing baffle 13 to be quickly installed onto the press-fitting device. The magnet 18 is located on the bottom surface of the first half 1000. For example, a recess is provided on the bottom surface of the first half 1000, and the magnet 18 is placed in the recess so that the bottom surface of the magnet 18 is coplanar with or lower than the bottom surface of the first half 1000. The magnet 18 is fixed to the base 10 by adhesive bonding. There are four magnets 18, which are evenly arranged around the first receiving hole 10000.

[0072] like Figure 9 As shown, optionally, the bushing baffle pressure head also includes a positioning block 19, which is fixed to the base 10 and used to position the bushing baffle 13. This configuration prevents the bushing baffle 13 from rotating. The positioning block 19 is cuboid in shape. The width of the positioning block 19 is the same as the width of the notch 131 in the bushing baffle 13. The height of the positioning block 19 is the same as the depth of the notch 131 in the bushing baffle 13. The positioning block 19 completes the positioning of the bushing baffle 13 when it is embedded in the notch 131. The positioning block 19 is made of steel. The positioning block 19 is fixed to the base 10 by welding or integral molding.

[0073] like Figure 9As shown, optionally, there are two positioning blocks 19, which are symmetrically arranged about the central axis of the guide post 11. This arrangement improves the reliability of the positioning blocks 19 in preventing the bushing baffle 13 from rotating. The two positioning blocks 19 are evenly distributed around the first receiving hole 10000.

[0074] Working principle of bushing baffle pressure head:

[0075] Please also refer to Figure 1 , Figure 2 and Figure 9 During the pressing of the bushing baffle 13, the bushing 14 is placed below the bushing baffle 13, and the two are separated at this time. The bushing baffle press head is fixed to the pressing device (e.g., a servo press). The bushing baffle 13 is fixed to the base 10 using the magnet 18 at the bottom of the base 10, and the guide post 11 passes through the center hole of the bushing baffle 13. The insert 15 is used to hold the two toothed blocks 130 on the bushing baffle 13, and the two positioning blocks 19 are respectively embedded into the two notches 131 on the bushing baffle 13.

[0076] Please also refer to Figure 1 , Figure 2 and Figure 9 Then, the pressing device drives the bushing baffle press head and the bushing baffle 13 to move downwards. When the bushing baffle 13 moves downwards, the guide post 11 passes through the center hole of the bushing 14, and the insert 15 is embedded in the groove 140 of the bushing 14. When the bushing baffle 13 and the bushing 14 come into contact, the two toothed blocks 130 are pressed into the two grooves 140 of the bushing 14, thereby completing the pressing of the bushing baffle 13. After the pressing is completed, the bushing baffle press head can be pushed upwards to remove the bushing baffle 13 and the bushing 14.

[0077] The bushing baffle pressure head provided in the embodiments of this application has been described in detail above. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope.
