Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a high-precision positioning drill jig for a needle chuck bench drill. Background Technology

[0002] The sewing machine needle chuck is an important component of a sewing machine, used to fix the needle and control its movement. It is usually made of metal and has the function of clamping the needle and moving it in a specific direction to ensure that the needle can pass through the fabric for sewing. During the manufacturing process, holes need to be drilled on its surface to facilitate connection and fixation with the sewing machine base and accessories. It usually has needle mounting holes and needle fixing holes, and the needle mounting holes and needle fixing holes are perpendicular to each other.

[0003] However, existing sewing machine needle chuck punching equipment requires the needle chuck material to be fixed with a clamp before drilling holes in it. Since the needle chuck requires a large number of holes at different horizontal positions, workers need to disassemble the clamp and flip the needle chuck material, making the process very cumbersome. Furthermore, after drilling, internal threads often need to be tapped, requiring a dedicated tapping machine for subsequent processing. This is not only time-consuming and labor-intensive but also inconvenient for continuous processing, significantly reducing processing efficiency and warranting improvement.

[0004] Therefore, this application proposes a high-precision positioning drill jig for a needle chuck bench drill to solve the problems in the background art. Utility Model Content

[0008] The drilling mechanism includes a cylinder, a moving plate, a motor, and a drilling bit. Two cylinders are fixedly mounted on the bracket, and the output ends of the two cylinders are fixedly connected to the same moving plate. Through the coordinated design of the control panel, the drilling mechanism, the tapping mechanism, and the drill jig, the needle chuck only needs to be installed into the mold groove on the drill jig. Under the control and drive of the tapping and drilling mechanisms by the control panel, the needle chuck can be continuously drilled and tapped, greatly improving convenience and processing efficiency.

[0009] A further feature of this invention is that three electric motors are fixedly mounted on the movable plate, and each of the three electric motors has a drilling bit installed at its output end. One end of each of the three drilling bits corresponds to the needle chuck. Driven by the three electric motors, the three drilling bits rotate and act on the needle chuck, thereby achieving the effect of drilling a hole in the needle chuck.

[0012] A further feature of this invention is that the tapping mechanism includes a second cylinder, a second moving plate, a second electric motor, and a tapping drill bit. The second cylinder is fixedly mounted on the bracket, and the output end of the second cylinder corresponds to the drill jig, which is used to drive the two tapping drill bits to move horizontally.

[0013] A further feature of this invention is that a movable plate is fixedly connected to the output end of the cylinder two, and two electric motors are fixedly installed on the movable plate two. Each of the output ends of the two electric motors is equipped with a tapping drill bit, and one end of each of the two tapping drill bits corresponds to the needle chuck. The two tapping drill bits are driven by the two electric motors two to perform tapping processing on the needle chuck.

[0014] A further feature of this invention is that: one end of the drill jig has two tapping holes, and the two tapping holes correspond to the two tapping drill bits respectively, so as to facilitate the two tapping drill bits to accurately tap the needle chuck.

[0015] A further feature of this invention is that both electric motors and cylinders are connected to the control panel, and the two electric motors and cylinders are controlled and driven by a preset program in the control panel.

[0016] A further feature of this invention is that the bottom of the drill jig is provided with a discharge groove, which is connected to the two tapping holes to facilitate the discharge of waste material.

[0017] A further feature of this invention is that a discharge port is provided on the drilling platform, and the discharge port corresponds to the bottom of the drilling jig, which further facilitates the discharge of waste materials.

[0018] The beneficial effects of this utility model are: through the cooperative design between the control panel, the drilling mechanism, the tapping mechanism and the drill jig, the needle chuck only needs to be installed into the mold groove on the drill jig, and under the control and drive of the tapping mechanism and the drilling mechanism by the control panel, the needle chuck can be continuously drilled and tapped, which greatly improves convenience and processing efficiency.

Two cylinders 51 are fixedly installed on the bracket 4, and the output ends of the two cylinders 51 are fixedly connected to the same moving plate 52. Through the cooperative design between the control panel 7, the drilling mechanism 5, the tapping mechanism 6, and the drill jig 2, the needle chuck 3 can be installed into the mold groove on the drill jig 2. Under the control and drive of the tapping mechanism 6 and the drilling mechanism 5 on the control panel 7, the needle chuck 3 can be continuously drilled and tapped, which greatly improves convenience and processing efficiency.

[0030] In this embodiment, three motors 53 are fixedly installed on the movable plate 52. Each of the three motors 53 has a drilling bit 54 installed at its output end. One end of each of the three drilling bits 54 corresponds to the needle chuck 3. Driven by the three motors 53, the three drilling bits 54 rotate and act on the needle chuck 3, thereby achieving the effect of drilling holes in the needle chuck 3.

[0031] In this embodiment, the drill jig 2 has three through holes 9, which correspond to three drilling bits 54 respectively, so that the three drilling bits 54 can pass through the needle chuck 3 and facilitate the discharge of waste materials.

[0032] In this embodiment, the three electric motors 53 and the two cylinders 51 are all connected to the control panel 7, and the three electric motors 53 and the two cylinders 51 are driven and controlled by the preset program in the control panel 7.

[0033] In this embodiment, the tapping mechanism 6 includes a second cylinder 61, a second moving plate 62, a second electric motor 63, and a tapping drill bit 64. The second cylinder 61 is fixedly installed on the bracket 4.

[0034] In this embodiment, a movable plate 62 is fixedly connected to the output end of cylinder 61. Two electric motors 63 are fixedly installed on the movable plate 62. A tapping drill bit 64 is installed at the output end of each of the two electric motors 63. One end of each tapping drill bit 64 corresponds to the needle chuck 3. The two tapping drill bits 64 are driven by the two electric motors 63 to tap the needle chuck 3.

[0035] In this embodiment, two tapping holes 10 are provided at one end of the drill jig 2. The two tapping holes 10 correspond to two tapping drill bits 64 respectively, so that the two tapping drill bits 64 can accurately tap the needle chuck 3.

[0040] First, the needle chuck 3 is placed in the mold groove on the drill jig 2. Then, the moving plate 52 is driven by the two cylinders 51 to move the three drilling bits 54 downward a certain distance through the three electric motors 53. At the same time, the three drilling bits 54 are rotated and act on the needle chuck 3 through the drive of the three electric motors 53, thereby achieving the effect of drilling the needle chuck 3.

[0041] Driven by cylinder 2 61, moving plate 2 62 moves two tapping drill bits 64 a certain distance toward needle chuck 3 via two electric motors 2 63, causing the two tapping drill bits 64 to pass through the two tapping holes 10 and interact with needle chuck 3. At the same time, driven by the two electric motors 2 63, the two tapping drill bits 64 perform tapping processing on needle chuck 3.

[0042] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, the needle chuck 3 can be quickly drilled and tapped, improving convenience and processing efficiency.
