Description

Technical Field

[0001] This utility model relates to the technical field of terminal block processing equipment, and more specifically, to a deburring device for terminal block stamping. Background Technology

[0002] Terminal blocks, as core components of electrical connections, are widely used in home appliances, automobiles, industrial equipment, and other fields. The stamping precision of their terminals directly affects the stability and safety of electrical connections. During the stamping process of terminal blocks, irregular burrs are easily generated on the sides of the terminals at the ends of the copper pillars after stamping. If these burrs are not completely removed, they can cause terminal assembly jamming, poor electrical contact, and even localized heating when current flows, posing a risk of short circuit. Deburring equipment is a key post-processing equipment in the stamping production of terminals. Existing deburring equipment mostly uses simple clamps to fix copper pillars and terminals, lacking a dual positioning structure for the center hole and copper pillars. This causes the terminals to easily deflect radially or tilt axially during processing. This positioning deviation will cause inconsistent contact depth between the deburring tool and the side of the terminal, resulting in defects such as burrs not being cut off in some areas and the terminal body being scratched in some areas. Some deburring devices use a motor-driven grinding wheel to remove burrs from terminals. However, because the sides of terminals are curved, it is difficult for the grinding wheel to fit against the curved surface and perform the grinding operation, affecting the deburring effect. Therefore, we propose a deburring device for terminal stamping. Utility Model Content

[0003] The purpose of this invention is to provide a deburring device for stamping terminals, so as to solve the defects mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A deburring device for stamping terminals includes a copper pillar and a terminal block located at the end of the copper pillar. The terminal block has a central hole. An upper pad is located below the copper pillar. A copper pillar positioning seat is fixedly installed on the upper surface of the upper pad. The copper pillar positioning seat has an annular groove for the copper pillar to be inserted. A positioning protrusion is fixedly installed on the upper surface of the upper pad, and the positioning protrusion is inserted into the central hole. Two symmetrical hydraulic cylinders mounted on an external frame are located above the upper pad. A blade holder plate is detachably installed at the end of the telescopic shaft of the two hydraulic cylinders. A deburring cutting blade is detachably installed on the bottom surface of the blade holder plate. The deburring cutting blade acts downward on the terminal block for cutting off side burrs.

[0005] Preferably, a processing platform is provided below the upper pad, and the processing platform is installed on the external frame.

[0006] Preferably, a fixing seat is fixedly installed on the bottom surface of the upper pad, and the fixing seat is detachably installed on the processing platform.

[0007] Preferably, the copper pillar positioning base has inclined surfaces on both its left and right sides, and the inclined surfaces are inclined downward at 30 to 40 degrees. This design makes it less likely for the sides of the copper pillar positioning base to become hard-to-clean areas, making subsequent debris removal easier.

[0008] Preferably, a crossbeam is provided above the upper pad, the hydraulic cylinder is fixedly installed on the crossbeam, and the crossbeam is fixedly installed on the external frame.

[0009] Preferably, a bolt plate is fixedly installed at the end of the telescopic shaft of the hydraulic cylinder, and the tool holder plate is detachably installed on the bottom surface of the two bolt plates; This feature facilitates the loading and unloading of the tool holder plate.

[0010] Preferably, a fixed support is fixedly installed on the deburring and cutting blade, and the fixed support is detachably installed on the bottom surface of the blade holder plate by a plurality of fastening bolts; This setting facilitates the loading and unloading of deburring and cutting blades.

[0011] Preferably, a copper pillar is provided at the end of the deburring and cutting blade, and the copper pillar extends through the copper pillar through the reserved gap. This feature ensures that the deburring and cutting blade does not damage the copper pillar as it moves downwards. Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model adopts a dual positioning structure of copper column positioning seat and positioning protrusion. The annular groove of the copper column positioning seat allows the copper column to be inserted, and the positioning protrusion is inserted into the center hole of the terminal block. This can restrict the position of the terminal block from both radial and axial directions, avoiding radial offset or axial tilt during processing. It ensures that the deburring cutting blade has a uniform contact depth with the side of the terminal block, which can thoroughly cut off the burrs without damaging the terminal block body, thus solving the processing defects caused by positioning deviation of traditional devices.

[0012] 2. This utility model adopts a structure in which a hydraulic cylinder drives the deburring and cutting blade. The hydraulic cylinder drives the blade holder plate and the deburring and cutting blade to act downward on the side of the terminal to complete the removal of side burrs. Compared with traditional grinding wheels, the cutting blade can better adapt to the arc-shaped side of the terminal, closely fit and accurately cut the burrs, avoiding the problem of poor deburring effect caused by the grinding wheel's difficulty in fitting the arc surface, and greatly improving the thoroughness and efficiency of burr removal.

[0013] 3. This utility model optimizes the detachable design of each component and the cleaning auxiliary structure. The blade holder plate can be detached and installed via bolt plates. The deburring and cutting blades can be easily installed and removed with the help of fixed supports and fastening bolts, facilitating quick blade replacement. The beveled design on both sides of the copper column positioning seat reduces cleaning dead angles and facilitates subsequent cleaning of debris. At the same time, the reserved gap between the copper column of the deburring and cutting blade can avoid damage to the copper column, taking into account both operational convenience and structural protection, and improving the overall practicality and maintenance efficiency of the device.

Please see Figures 1-4This utility model provides a technical solution: a deburring device for stamping terminals, including a copper pillar 1 and a terminal 10 disposed at the end of the copper pillar 1. The terminal 10 is provided with a central hole 11. An upper pad 21 is provided below the copper pillar 1. A copper pillar positioning seat 22 is fixedly installed on the upper surface of the upper pad 21. An annular groove 221 for the copper pillar 1 to be inserted is provided in the copper pillar positioning seat 22. A positioning protrusion 23 is fixedly installed on the upper surface of the upper pad 21. The positioning protrusion 23 and the central hole 11 are inserted into each other to achieve a double fixation of the copper pillar 1 and the terminal 10 from the radial and axial directions, so that the two will not be radially offset or axially tilted during the deburring process, and ensure that the processing position of the deburring cutting blade 33 on the side of the terminal 10 is accurate.

[0017] In this embodiment, two symmetrical hydraulic cylinders 30 are provided above the upper pad plate 21 and mounted on the external frame. A blade holder plate 32 is detachably installed at the end of the telescopic shaft of the two hydraulic cylinders 30. A deburring cutting blade 33 is detachably installed on the bottom surface of the blade holder plate 32. The deburring cutting blade 33 acts downward on the terminal 10 for cutting off the side burrs. The hydraulic cylinders 30 drive the blade holder plate 32 to drive the deburring cutting blade 33 downward, which can quickly cut off the side burrs of the terminal 10. The size of the deburring cutting blade 33 is adapted to the size of the terminal 10, so that the cutting blade is more suitable for the arc-shaped side of the terminal than the traditional grinding wheel, avoiding burr residue and improving the efficiency and thoroughness of deburring.

[0018] like Figure 1 and Figure 3 As shown, a processing platform 2 is provided below the upper pad 21, and the processing platform 2 is installed on the external frame. A fixing seat 20 is fixedly installed on the bottom surface of the upper pad 21. The fixing seat 20 is detachably installed on the processing platform 2.

[0019] like Figure 3 As shown, inclined surfaces 222 are provided on both the left and right sides of the copper column positioning seat 22. The inclined surfaces 222 are set at a downward inclination of 30 degrees to 40 degrees to reduce the cleaning dead angles on the sides of the copper column positioning seat 22, making it easier to clean the debris generated during deburring, avoiding the accumulation of debris from affecting the processing quality of subsequent wiring terminals, and ensuring the continuous and stable operation of the device.

[0020] Specifically, a crossbeam 3 is provided above the upper pad 21, and the hydraulic cylinder 30 is fixedly installed on the crossbeam 3. The crossbeam 3 is fixedly installed on the external frame. The crossbeam 3 provides a stable mounting base for the hydraulic cylinder 30, ensuring that the hydraulic cylinder 30 drives the deburring cutting blade 33 to move with stable force and will not cause processing deviation due to shaking, thus further ensuring the deburring accuracy.

[0021] Furthermore, a bolt plate 31 is fixedly installed at the end of the telescopic shaft of the hydraulic cylinder 30, and the tool holder plate 32 can be detachably installed on the bottom surface of the two bolt plates 31. The tool holder plate 32 can be installed and removed without complicated disassembly steps, reducing the difficulty of subsequent maintenance or replacement of the tool holder plate 32.

[0022] In addition, a fixed support 332 is fixedly installed on the deburring cutting blade 33. The fixed support 332 is detachably installed on the bottom surface of the blade holder plate 32 by multiple fastening bolts, making it easier to install and remove the deburring cutting blade 33. When the blade is worn, it can be quickly replaced, reducing the downtime for equipment maintenance.

[0023] It is worth noting that a copper post reserved gap 331 is provided at the end of the deburring and cutting blade 33. The copper post 1 passes through the copper post reserved gap 331 to avoid collision with the copper post 1 when the deburring and cutting blade 33 moves downward, thus protecting the copper post 1 from damage and ensuring the integrity of the overall structure of the terminal block.

[0024] Finally, it should be noted that the hydraulic cylinder 30, the corresponding hydraulic source, the corresponding control system, and the external power supply of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0025] When using the deburring device for punching terminals of this utility model, the processing platform 2 and the crossbeam 3 are fixed on the external frame. The upper pad 21 is installed on the processing platform 2 through the fixing seat 20. The copper column 1 is inserted into the annular groove 221 of the copper column positioning seat 22. At the same time, the center hole 11 of the terminal 10 is inserted into the positioning protrusion 23 to complete the dual positioning of the copper column 1 and the terminal 10. Start the hydraulic cylinder 30, drive the tool holder plate 32 to move the deburring cutting blade 33 downward, the deburring cutting blade 33 is sleeved on the terminal 10 and moves downward to cut the burrs on the side of the terminal 10.
