Technical Field

[0001] This utility model relates to an auxiliary fixture for tapping end caps, specifically to a tapping machine for tapping end caps. Background Technology

[0002] In the attached Figure 6 During the tapping process of the five holes on the end face of the end cap shown, because the end cap is irregularly shaped, it is difficult to achieve fast and accurate positioning using traditional fixtures, resulting in low processing efficiency.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] To address the aforementioned technical problem of low processing efficiency caused by the difficulty in quickly and accurately positioning end caps using traditional fixtures in the prior art, this utility model solves the problem by providing an auxiliary fixture for tapping end caps. The auxiliary fixture includes a base, a sliding seat, and a positioning seat. The sliding seat is slidably connected to the base, and the positioning seat is connected to the sliding seat. The positioning seat has an arc-shaped positioning edge that can engage the inner wall of the end cap, and a support edge that contacts the lower end face of the end cap. The positioning seat also includes a first positioning post that engages the first through hole of the end cap and a second positioning post that engages the second through hole of the end cap. A moving handle is provided on the sliding seat for moving the sliding seat.

[0005] As described above, an auxiliary fixture for tapping end caps has a positioning base with multiple grooves that simultaneously intersect with an arc-shaped positioning edge and a support edge. The arc-shaped positioning edge is located between two adjacent grooves, and the support edge is located between two adjacent grooves.

[0006] As described above, an auxiliary fixture for tapping end caps has a first guide arc surface at the upper end of the first positioning post to facilitate the first positioning post entering the first through hole, and a second guide arc surface at the upper end of the second positioning post to facilitate the second positioning post entering the second through hole.

[0007] As described above, an auxiliary fixture for tapping end caps includes a sliding assembly between the base and the sliding seat. The sliding assembly comprises a guide rail and a slider. The guide rail is connected to the base, and the slider is connected to the bottom of the sliding seat. The slider is slidably connected to the guide rail.

[0008] As described above, an auxiliary fixture for tapping end caps includes a pad between the guide rail and the base. The pad has a first positioning surface that contacts the bottom surface of the guide rail, and a second positioning surface that contacts the side surface of the guide rail.

[0009] As described above, an auxiliary clamp for tapping end caps includes a movable handle comprising two screw sections with a grip section between them. The front ends of the screw sections pass through a sliding seat, and two nuts for locking the screw sections onto the sliding seat are threaded onto the screw sections.

[0010] This embodiment of a tapping machine for end caps includes: a machine base, a worktable, and a tapping mechanism. The worktable is provided with an auxiliary fixture as described above. The worktable is mounted on the machine base, and the tapping mechanism is mounted on the machine base to tap the end cap held by the auxiliary fixture.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses the arc-shaped positioning edge on the positioning seat to position the end cap horizontally, and the support edge on the positioning seat to position the end cap vertically. The first and second positioning pins on the positioning seat provide auxiliary positioning to ensure positioning accuracy, while preventing the end cap from rotating horizontally. This enables the end cap to be positioned quickly and accurately, reduces the clamping time during tapping, and improves tapping efficiency.

[0013] 2. The positioning seat can be moved from directly below the tapping mechanism to the outside by moving the handle, which facilitates the loading and unloading of the upper cover. Attached Figure Description

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 6 As shown, this utility model has two embodiments, which will now be described separately.

[0022] Example 1:

[0023] like Figures 1 to 3 As shown in this embodiment, an auxiliary fixture for tapping end caps includes a base 11, a sliding seat 12, and a positioning seat 13. The sliding seat 12 is slidably connected to the base 11, and the positioning seat 13 is connected to the sliding seat 12. The positioning seat 13 has an arc-shaped positioning edge 1301 that can engage with the inner wall of the end cap 800, and a support edge 1302 that contacts the lower end face of the end cap 800. The positioning seat 13 has a first positioning post 131 that can engage with the first through hole 801 of the end cap 800, and a second positioning post 132 that can engage with the second through hole 802 of the end cap 800. The sliding seat 12 has a moving handle 14 for moving the sliding seat 12. This invention uses the arc-shaped positioning edge on the positioning seat to position the end cap horizontally, and the support edge on the positioning seat to position the end cap vertically. The first and second positioning pins on the positioning seat provide auxiliary positioning to ensure positioning accuracy, while preventing the end cap from rotating horizontally. This enables the end cap to be positioned quickly and accurately, reducing the clamping time during tapping and improving tapping efficiency. By moving the handle, the positioning seat can be moved from directly below the tapping mechanism to the outside, facilitating the loading and unloading of the upper end cap.

[0024] In this embodiment, in order to enable the first positioning post to be quickly and accurately inserted into the first through hole, a first guide arc surface 1311 is provided at the upper end of the first positioning post 131 to facilitate the first positioning post 131 entering the first through hole 801; in order to enable the first positioning post to be quickly and accurately inserted into the first through hole, a second guide arc surface 1321 is provided at the upper end of the second positioning post 132 to facilitate the second positioning post 132 entering the second through hole 802.

[0025] In this embodiment, a sliding assembly 15 is provided between the base 11 and the sliding seat 12. The sliding assembly 15 includes a guide rail 151 and a slider 152. The guide rail 151 is connected to the base 11, and the slider 152 is connected to the bottom of the sliding seat 12. The slider 152 is slidably connected to the guide rail 151.

[0026] To facilitate accurate installation of the guide rail, a pad 153 is provided between the guide rail 151 and the base 11. The pad 153 has a first positioning surface 1531 that contacts the bottom surface of the guide rail 151, and a second positioning surface 1532 that contacts the side surface of the guide rail 151. During installation, the side surface of the guide rail can be in contact with the second positioning surface 1532 as the installation reference.

[0027] In this embodiment, the movable handle 14 includes two screw sections 141, with a grip section 142 located between the two screw sections 141. The front ends of the screw sections 141 pass through the sliding seat 12, and two nuts 143 are threaded onto the screw sections 141 to lock them onto the sliding seat 12. The position of the screw sections 141 relative to the sliding seat can be adjusted by the engagement of the two nuts 143, thereby adjusting the position of the grip section 142 relative to the sliding seat.

[0028] like Figure 4 As shown, this embodiment of a tapping machine for end caps includes: a base 2, a worktable 3, and a tapping mechanism 4. The worktable 3 is equipped with an auxiliary clamp 1 as described above. The worktable 3 is mounted on the base 2, and the tapping mechanism 4 is mounted on the base 2 to tap the end cap 800 held by the auxiliary clamp 1. This tapping machine, by mounting the auxiliary clamp on the worktable and tapping the end cap using the tapping mechanism, achieves rapid positioning of the end cap and has the advantage of high working efficiency.

[0029] Example 2:

[0030] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the positioning base 13 is provided with multiple grooves 1303 that intersect with both the arc-shaped positioning edge 1301 and the support edge 1302. The arc-shaped positioning edge 1301 is located between two adjacent grooves 1303, and the support edge 1302 is located between two adjacent grooves 1303. With the above design, when the inner wall of the end cap is stuck on the arc-shaped positioning edge, reducing the contact area between the inner wall of the end cap and the arc-shaped positioning edge can reduce friction. At the same time, an auxiliary part (such as a plastic rod) can be inserted into the groove to remove the end cap from the positioning base.

[0031] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
