Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to a shearing machine that can be adjusted longitudinally. Background Technology

[0002] A circuit board shearing machine is a specialized piece of equipment used in the electronics manufacturing industry. Its main function is to precisely cut entire or continuous circuit boards into individual units according to design dimensions. Its working principle typically involves using high-precision mechanical cutters, hydraulic or pneumatic systems to shear or punch the circuit boards. It can handle circuit boards made of various materials such as FR-4 and aluminum substrates. The equipment features a high degree of automation, high cutting accuracy, and stable efficiency, effectively avoiding problems such as rough edges and dimensional deviations caused by manual cutting. It is widely used in PCB (printed circuit board) production and electronic assembly, and is one of the key pieces of equipment for improving circuit board processing quality and production efficiency.

[0003] Chinese utility model patent with announcement number CN221436619U discloses a cutting device for power supply processing, which includes "a worktable, two adjusting devices and two fixing components, the worktable having two mounting cavities for movably connecting the two adjusting devices, and the two fixing components being fixedly connected to both sides of the worktable"; however, the cutting device in this device can only perform horizontal cutting on the circuit board and cannot change the cutting direction, thus failing to meet the cutting needs of various circuit boards. Utility Model Content

[0004] The purpose of this invention is to provide a longitudinally adjustable shearing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a longitudinally adjustable shearing machine, including a shearing machine frame, wherein a clamping assembly is provided inside the shearing machine frame, and a clamping assembly is provided on the upper part of the shearing machine frame;

[0006] The shearing machine frame includes a shearing machine housing, and the upper surface of the shearing machine housing has two cutting grooves, which are arranged in a cross shape.

[0007] The clamping assembly includes a dual-head motor, which is slidably mounted inside the shearing machine housing via a base. Threaded rotating rods are rotatably mounted on both sides of the dual-head motor. A connecting rod is mounted on the outer surface of each threaded rotating rod via a sliding block. A clamping block is fixedly mounted on the upper end of each connecting rod.

[0008] The cutting assembly includes a connecting block, an insert cylinder is fixedly installed at the upper end of the connecting block, two symmetrically distributed limiting blocks are fixedly installed on the outer surface of the insert cylinder, a sliding block is slidably installed at the upper end of the connecting block, a connecting hole is opened at the bottom of the sliding block, two sliding grooves are opened on the surface of the connecting hole, four sliding grooves are opened inside the sliding block, and the four positioning slots are symmetrically distributed in a cross shape.

[0009] The beneficial effects of this utility model are as follows: by pressing the connecting block upward, the limiting blocks on both sides of the insertion cylinder are disengaged from the interior of two of the transmission rods. Then, the connecting block is rotated so that the limiting blocks rotate 90 degrees and thus overlap with the interior of the other two positioning slots. Then, the connecting block is lowered and the spring holds it in place. This allows the device to change the shearing direction according to actual needs during use, thereby improving the efficiency and practicality of the device.

[0010] To achieve mobile clamping:

[0011] The design further includes: bearings rotatably mounted on both sides of the shearing machine housing, and two sliding rails parallel to each other at the upper end of the shearing machine housing.

[0012] By adopting the above technical solution, bearings are installed on both sides of the inner wall of the shearing machine housing, and one side of each threaded rod is installed inside the bearing. When the threaded rod rotates, it drives the entire device to move, which facilitates the movement of the subsequent clamping blocks.

[0013] To achieve parallel movement of the cutting tool:

[0014] The further configuration is as follows: a blade holder is slidably mounted on the upper end of the shearing machine housing, a slide rod is fixedly mounted on the middle of the blade holder, and limit sliders are fixedly mounted on both sides of the lower end of the blade holder, with the limit sliders sliding inside two sliding tracks respectively.

[0015] By adopting the above technical solution, the two sliding rails are set in parallel, and the two limiting sliders at the bottom of the tool holder slide inside the sliding rails on both sides. This allows the tool holder to move smoothly above the device, reducing the cutting error of the cutting tool when the subsequent device is working.

[0016] To achieve the cutting of the circuit board:

[0017] The configuration is further defined as follows: a transmission rod is rotatably mounted inside the connecting block, one side of the transmission rod is rotatably connected to a servo motor, and the other side of the servo motor is rotatably mounted with a cutting tool.

[0018] By adopting the above technical solution, the servo motor is started, which drives the transmission rod to rotate, and then drives the cutting tool to rotate, so as to cut the circuit board.

[0019] To achieve the fixation of the connecting block:

[0020] The sliding block is further configured such that a square limiting hole is provided inside the sliding block, the square limiting hole is sleeved on the outer surface of the sliding rod, and a spring is fixedly installed inside the sliding block.

[0021] By adopting the above technical solution, when the connecting block is adjusted to the correct direction, the limiting blocks on both sides of the upper part of the connecting block will fall into the positioning slot by releasing the connecting block. At this time, the spring rebounds and holds the upper opening of the insertion tube, preventing the connecting block from shaking or shifting, which would affect the cutting accuracy.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0030] Please see Figures 1 to 5A longitudinally adjustable shearing machine includes a shearing machine frame 1, a clamping assembly 2 inside the shearing machine frame 1, and a clamping assembly 2 on the upper part of the shearing machine frame 1.

[0031] The shearing machine frame 1 includes a shearing machine housing 101, and two cutting grooves 104 are provided on the upper surface of the shearing machine housing 101. The two cutting grooves 104 are distributed in a cross shape.

[0032] The clamping assembly 2 includes a dual-head motor 201, which is slidably mounted inside the shearing machine housing 101 via a base. Threaded rotating rods 202 are rotatably mounted on both sides of the dual-head motor 201. A connecting rod 203 is mounted on the outer surface of each threaded rotating rod 202 via a sliding block 307. A clamping block 204 is fixedly mounted on the upper end of each connecting rod 203.

[0033] The cutting assembly 3 includes a connecting block 301. A plug-in tube 305 is fixedly installed on the upper end of the connecting block 301. Two symmetrically distributed limiting blocks 306 are fixedly installed on the outer surface of the plug-in tube 305. A sliding block 307 is slidably installed on the upper end of the connecting block 301. A connecting hole 309 is opened at the bottom of the sliding block 307. Two sliding grooves 310 are opened on the surface of the connecting hole 309. Four sliding grooves 310 are opened inside the sliding block 307. The four positioning slots 312 are symmetrically distributed in a cross shape.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, bearings 102 are rotatably mounted on both sides of the shearing machine housing 101, and two sliding rails 103 are provided at the upper end of the shearing machine housing 101, with the two sliding rails 103 being parallel to each other.

[0035] In this embodiment, as Figure 1 and Figure 2 As shown, a blade holder 105 is slidably mounted on the upper end of the shearing machine housing 101, a slide rod 106 is fixedly mounted on the middle of the blade holder 105, and limit sliders 107 are fixedly mounted on both sides of the lower end of the blade holder 105. The limit sliders 107 slide inside the two sliding tracks 103 respectively.

[0036] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, a transmission rod 302 is rotatably mounted inside the connecting block 301. One side of the transmission rod 302 is rotatably connected to a servo motor 303, and a cutting tool 304 is rotatably mounted on the other side of the servo motor 303.

[0037] In this embodiment, as Figure 1 , Figure 4 and Figure 5As shown, a square limiting hole 308 is provided inside the sliding block 307. The square limiting hole 308 is sleeved on the outer surface of the slide rod 106. A spring 311 is fixedly installed inside the sliding block 307.

[0038] The longitudinally adjustable shearing machine operates as follows:

[0039] First, the user aligns the limiting blocks 306 on both sides of the connector 305 with the two sliding grooves 310 inside the sliding block 307. Then, the user pushes the connector 305 into the sliding block 307. At this time, the spring 311 inside the sliding block 307 is compressed and contracts. When the limiting blocks 306 reach the appropriate position, the user rotates the connecting block 301, causing the limiting blocks 306 to displace the sliding grooves 310 and align with two of the positioning slots 312. Then, the user releases the connecting block 301, and the limiting blocks 306 fall into the positioning slots 312. When the spring 311 returns, it presses against the upper end of the connector cylinder 305, preventing the connecting block 301 from shaking during use. Then, the circuit board to be cut is placed on the table of the shearing machine housing 101. Next, the dual-head motor 201 (model: 120X103SRD18Z6) is started, driving the connecting rods 203 on both sides to rotate, which in turn drives the clamping blocks 204 on both sides to clamp towards the center. After clamping is complete, the sliding blade holder 105 is moved to the appropriate position, and then the servo motor 303 (model: GYB201) is started. D5-RC2) drives the transmission rod 302 to rotate. Since the connecting block 301 has a rotating shaft inside, the rotation of the transmission rod 302 will directly drive the cutting tool 304 to rotate. The sliding block 307 is slidable to cut the circuit board. When the circuit board needs to be cut longitudinally, simply press the connecting block 301 upward to make the limiting blocks 306 on both sides of the plug tube 305 disengage from the inside of two of the transmission rods 302. Then rotate the connecting block 301 to make the limiting blocks 306 rotate 90 degrees, so that they overlap inside the other two positioning slots 312. Then put the connecting block 301 down and let the spring 311 hold it in place. This changes the cutting angle of the device. Then, the cutting work can be carried out according to the above operation.
