Technical Field
[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for lead-free solder bars that is easy to maintain. Background Technology
[0002] The design of lead-free solder bar cutting equipment is similar to that of traditional solder bar cutting equipment, but special consideration must be given to the physical properties of lead-free solder, such as its lower melting point and greater brittleness. Lead-free solder is commonly used in the soldering of electronic products because its environmental friendliness meets modern manufacturing standards.
[0003] In existing lead-free solder bar cutting devices, the blades are mostly fixed to the blade holder with bolts. However, this fixing method makes the disassembly process cumbersome when replacing and maintaining the blades, which is inconvenient for workers to replace and maintain the cutting blades.

[0006] The quick-release assembly includes a limiting slide groove, a guide limiting plate slidably connected to the inner wall of the limiting slide groove, an operation button slidably connected to the surface of the guide limiting plate, a spring limiting rod slidably connected to the inner wall of the guide limiting plate, one end of the spring limiting rod away from the operation button being fixedly connected to the inner wall of the tool housing, a return spring being fixedly connected to the one end of the guide limiting plate away from the operation button, a connecting rod being fixedly connected to the one end of the guide limiting plate away from the operation button, a limiting slider being fixedly connected to the one end of the connecting rod away from the guide limiting plate, the outer wall of the limiting slider being slidably connected to the inner wall of the tool housing, and a cutting tool being slidably connected to the outer wall of the limiting slider.
[0007] As a further improvement to the above solution, the outer wall of the operation button is slidably connected to the inner wall of the tool housing, and the cutting tool is slidably connected to the outer wall of the tool housing.
[0008] As a further improvement to the above solution, two guide limiting plates are provided, which are symmetrically arranged around the center of the tool housing, and two spring limiting rods are provided, which are symmetrically arranged around the center of the tool housing.
[0009] With the above technical solution, by pressing the operation button inside the tool housing, the operation button will slide the symmetrically arranged guide limit plates to both sides along the limit groove. At the same time, the spring limit rod will slide towards the inner wall of the guide limit plate, so that the guide limit plate will press the symmetrically arranged reset springs to both sides.
[0010] As a further improvement to the above solution, the drive assembly includes a motor mounting base, a drive motor is fixedly connected to the top of the motor mounting base, a motor rotating rod is fixedly connected to the output end of the drive motor, and a rotating disk is fixedly connected to the end of the motor rotating rod away from the drive motor.
[0011] As a further improvement to the above solution, a rotating rod is fixedly connected to the surface of the rotating disk, a driving connecting rod is rotatably connected to the outer wall of the rotating rod, and a second rotating rod is rotatably connected to the inner wall of the end of the driving connecting rod away from the rotating rod. The second rotating rod is fixedly connected to the outer wall of the tool housing.
[0012] As a further improvement to the above solution, a cutting shell is fixedly connected to the bottom of the motor mounting base, a T-shaped groove is provided on the inner wall of the cutting shell, a T-shaped slider is slidably connected to the inner wall of the T-shaped groove, an clearance groove is provided on the top of the cutting shell, and the drive connecting rod is slidably connected to the inner wall of the clearance groove.
[0013] As a further improvement to the above solution, the T-shaped slider is fixedly connected to the outer wall of the tool housing, and two T-shaped sliders are provided, which are symmetrically arranged with the motor rotating rod as the center.
[0014] With the above technical solution, the drive motor is operated, the output end of the drive motor rotates the motor rotating rod, the motor rotating rod rotates the rotating disk, the rotating disk rotates the rotating rod, the rotating rod rotates the drive connecting rod, and the drive connecting rod reciprocates to push the second rotating rod during the rotation of the rotating rod, while the drive connecting rod slides along the clearance groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention simplifies the cutting tool installation process and improves maintenance efficiency when the cutting tool needs to be disassembled and replaced. By pressing an operation button inside the tool housing, the button slides symmetrically arranged guide plates along the limiting grooves to both sides. Simultaneously, a spring limiting rod slides against the inner wall of the guide limiting plate, causing the guide limiting plate to press against the symmetrically arranged reset springs. The guide limiting plate then drives a connecting rod, which in turn drives a limiting slider, disengaging the limiting slider from the cutting tool surface.
[0017] This invention utilizes a drive motor to rotate a motor rod at its output end. The motor rod rotates a rotating disk, which in turn rotates the motor rod. The rotating disk then rotates the motor rod, which in turn rotates a drive connecting rod. During the rotation of the rotating rod, the drive connecting rod reciprocates and pushes the second rotating rod. Simultaneously, the drive connecting rod slides along the clearance groove. The second rotating rod pushes the tool housing, causing the tool housing to drive the T-shaped slider to slide up and down along the T-shaped groove. This allows the tool housing to drive the cutting tool to perform cutting operations. Attached Figure Description

[0031] The quick-release assembly 2 includes a limiting slide groove 201, a guide limiting plate 202 slidably connected to the inner wall of the limiting slide groove 201, an operation button 203 slidably connected to the surface of the guide limiting plate 202, a spring limiting rod 204 slidably connected to the inner wall of the guide limiting plate 202, one end of the spring limiting rod 204 away from the operation button 203 being fixedly connected to the inner wall of the tool housing 1, a return spring 205 being fixedly connected to the one end of the guide limiting plate 202 away from the operation button 203, a connecting rod 206 being fixedly connected to the one end of the guide limiting plate 202 away from the operation button 203, a limiting slider 207 being fixedly connected to the one end of the connecting rod 206 away from the guide limiting plate 202, the outer wall of the limiting slider 207 being slidably connected to the inner wall of the tool housing 1, and a cutting tool 208 being slidably connected to the outer wall of the limiting slider 207.
[0032] The operation button 203 is slidably connected to the inner wall of the tool housing 1, and the cutting tool 208 is slidably connected to the outer wall of the tool housing 1.
[0033] There are two guide limit plates 202, which are symmetrically arranged around the center of the tool housing 1. There are also two spring limit rods 204, which are symmetrically arranged around the center of the tool housing 1.
[0034] The drive assembly 3 includes a motor mounting base 301, a drive motor 302 is fixedly connected to the top of the motor mounting base 301, a motor rotating rod 303 is fixedly connected to the output end of the drive motor 302, and a rotating disk 304 is fixedly connected to the end of the motor rotating rod 303 away from the drive motor 302.
[0035] A rotating rod 305 is fixedly connected to the surface of the rotating disk 304. A driving connecting rod 306 is rotatably connected to the outer wall of the rotating rod 305. A second rotating rod 307 is rotatably connected to the inner wall of the end of the driving connecting rod 306 away from the rotating rod 305. The second rotating rod 307 is fixedly connected to the outer wall of the tool housing 1.
[0036] The bottom of the motor mounting base 301 is fixedly connected to the cutting housing 311. The inner wall of the cutting housing 311 is provided with a T-shaped slide groove 308.
