Description

Technical Field

[0001] This utility model relates to the field of four-axis machining technology for reinforcing steel sheets, specifically to an auxiliary device for four-axis machining of reinforcing steel sheets. Background Technology

[0002] The main purpose of reinforcing steel sheets is to increase the thickness and hardness of specific areas of the FPC (Flexible Printed Circuit). By attaching reinforcing steel sheets to a certain position or area of ​​the FPC, the mechanical strength of the FPC can be effectively enhanced, reducing the probability of bending or deformation during use. After the reinforcing steel sheets are initially shaped by cutting, they need to be milled by a machine tool. To improve milling efficiency, a four-axis machine tool is often used to further mill the two ends of the reinforcing steel sheets.

[0003] The aforementioned device lacks a structure for quickly aligning and fixing multiple steel plates to the fixed base, which means that the existing four-axis machine tool's reinforcing steel plate fixing base can only be milled one piece at a time. When processing multiple reinforcing steel plates, frequent disassembly and assembly of the steel plates is required, which is quite cumbersome. Based on the shortcomings of the existing technology, this utility model designs an auxiliary device for four-axis processing of reinforcing steel plates. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a four-axis machining auxiliary device for reinforcing steel sheets, which has the advantage of quickly aligning and fixing multiple steel sheets with a fixed base.

[0005] This utility model provides the following technical solution: a four-axis machining auxiliary device for reinforcing steel sheets, including a positioning plate, wherein the positioning plate is provided with a clamping mechanism for clamping the reinforcing steel sheets, and a centering mechanism is provided below the positioning plate for centering and fixing reinforcing steel sheets of different sizes with the positioning plate and the clamping mechanism. The centering mechanism includes a base frame, a support rod, a base plate, a fixed foot, a sliding sleeve, a base support plate, and a limiting bolt. The base frame is fixedly connected to the lower surface of the positioning plate. The support rod is inserted into the base frame. The base plate is fixedly connected to the bottom end of the support rod. The fixed foot is fixedly connected to the lower surface of the base plate. Four sets of sliding sleeves are sleeved on the support rod. The base support plate is fixedly connected to the four sets of sliding sleeves. The limiting bolt is threaded through and connected to a single extended sliding sleeve.

[0006] As a preferred technical solution of this utility model, the clamping mechanism includes a rotating shaft, threaded teeth, a screw head, a through hole, a chuck, a connecting plate, a threaded block, and a connecting frame. The rotating shaft is rotatably connected inside the positioning plate. The threaded teeth are fixedly connected to the rotating shaft. The screw head is fixedly connected to the outer end of the rotating shaft. The through hole is opened on the inner side of the positioning plate. The chuck is slidably inserted into the through hole. The connecting plate is fixedly connected to the inner end of the chuck. The threaded block is fixedly connected between the left and right sets of connecting plates. The connecting frame is fixedly connected between the left and right sets of connecting plates.

[0007] As a preferred technical solution of this utility model, a limiting groove is formed through the positioning plate, and a fixing head is fixedly connected to one side of the positioning plate.

[0008] As a preferred embodiment of this utility model, a scale line is provided on the side wall of a single support rod, and the inner end of the limiting bolt is in contact with the side wall of the support rod.

[0009] As a preferred technical solution of this utility model, the upper surface of the bottom support plate is provided with a limiting groove, and the size and position of the limiting groove are aligned with the limiting slot.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This four-axis machining auxiliary device for reinforcing steel sheets involves fixing the support rod and base plate to the table using fixed feet and loosening the limiting bolts. Then, the length of the batch of reinforcing steel sheets is measured. Based on half the length of the steel sheet, the base plate is moved up and down under the limit of the support rod and the sliding sleeve, as well as the indication of the scale on the support rod surface, until the position of the base plate corresponds to the value displayed on the support rod scale and half the length of the reinforcing steel sheet. Then, the limiting bolts are tightened to lock the base plate. The positioning plate is placed on the top of the support rod using the base frame. Then, the steel sheets are inserted one by one into the limiting groove and the limiting groove on the upper surface of the base plate. This device facilitates the centering and alignment of reinforcing steel sheets of different sizes with the positioning plate.

[0014] 2. This four-axis machining auxiliary device for reinforcing steel sheets involves inserting and centering the steel sheets, then using a hex wrench to turn the rotating shaft clockwise. The rotating shaft drives the threaded teeth to rotate, pushing the threaded block inward. The moving threaded block, through the connecting plate, drives the chuck to move within the through hole, clamping and fixing the steel sheet in the limiting groove. Finally, the positioning plate containing the fixed steel sheet is connected to the milling machine's clamping seat using a fixing head. This device facilitates the clamping and machining of reinforcing steel sheets of different sizes. Attached Figure Description

By setting a bottom support plate 306, bottom support is provided for the steel sheet inserted into the limiting groove 101. By setting a scale on support rod 302, sliding sleeve 305 and limiting bolt 307, the position of bottom support plate 306 can be adjusted according to the length data of steel sheet, so that after the steel sheet is inserted into the limiting groove 101, it can fall directly into the groove on the upper surface of bottom support plate 306, so that the steel sheet is aligned with the center of positioning plate 1 and clamped and fixed by clamping mechanism 2.

[0021] Please see Figure 3 The clamping mechanism 2 includes a rotating shaft 201, threaded teeth 202, a screw head 203, a through hole 204, a chuck 205, a connecting plate 206, a threaded block 207, and a connecting frame 208.

[0023] Working principle: When a four-axis machining auxiliary device for reinforcing steel sheets is used, in the initial state, the limiting groove 101 is first opened through the positioning plate 1. A fixing head 102 is set on one side of the positioning plate 1, and a clamping mechanism 2 is set in the positioning plate 1 and the limiting groove 101 to clamp and fix the cut reinforcing steel sheets and perform milling and turning. A support rod 302, a base plate 303 and a fixing foot 304 are inserted into the bottom frame 301 fixedly connected to the bottom of the positioning plate 1.

Then, tighten limit bolts 307 to lock bottom support plate 306. At this time, use bottom frame 301 to place positioning plate 1 on top of support rod 302. Then, insert the steel plates one by one into the limiting groove 101 and the limiting groove on the upper surface of the bottom support plate 306. After the steel plates are inserted and aligned in the center, use a hex wrench to insert the screw head 203 and turn the rotating shaft 201 clockwise. The rotating shaft 201 drives the threaded teeth 202 to rotate and push the threaded block 207 to move inward.
