Description

Technical Field

[0001] The utility model belongs to the technical field of PCB milling cutter production, and relates to a welding detection device for PCB milling cutter production. Background Technique

[0002] The Chinese name of PCB is printed circuit board, also known as printed wiring board. It is an important electronic component, a support for electronic components, and at the same time a carrier for electrical connection of electronic components. Since it is made by electronic printing technology, it is called printed circuit board. In the processing of PCB, a PCB milling cutter is needed to cut grooves on the board to facilitate circuit design, so the PCB milling cutter has been widely used.

[0003] When producing PCB milling cutters, in order to reduce production costs, different materials are used for the shank and the cutting edge. After welding, a PCB milling cutter blank is formed. After welding, it is necessary to detect whether the shank and the cutting edge of the PCB milling cutter blank are inclined to ensure the product quality. The existing detection is generally carried out by precision electronic instruments such as industrial cameras or electronic theodolites, and the cost is relatively high.

[0004] Based on this, we have designed a welding detection device for PCB milling cutter production. Summary of the Utility Model

[0005] The purpose of the utility model is to address the above problems existing in the prior art and propose a welding detection device for PCB milling cutter production. The technical problem to be solved by this device is: how to reduce the cost of detecting the coaxiality of the shank and the cutting edge of the PCB milling cutter blank.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A welding detection device for PCB milling cutter production includes a base. A vertical slide rail is fixed on the base. A lifting seat is slidably arranged on the vertical slide rail, and a tension spring is arranged between the lifting seat and the top of the vertical slide rail. A lifting frame is fixed to the side end of the lifting seat, and a dial indicator is fixed on the lifting frame, and the probe of the dial indicator is vertically downward. A rotating shaft is rotatably arranged on the lifting frame, and a handwheel and a rotating wheel are respectively fixed at both ends of the rotating shaft. The rotating wheel is perpendicularly distributed with the dial indicator. A support plate is fixed on the base, and a V-shaped channel steel is fixed on the support plate.

[0008] A soft rubber ring is fixed on the outer side of the rotating wheel.

[0009] With the above structure, during use, the operator places the handle of the PCB milling cutter bar stock after welding in the V-shaped channel steel, and makes the cutting edge fully exposed from the V-shaped channel steel. Then, the operator pulls down the lifting frame through the hand ball. At this time, the lifting frame drives the dial indicator to descend synchronously. When the soft rubber ring contacts the PCB bar stock, the probe of the dial indicator abuts against the cutting edge. Then, the operator can drive the rotating wheel to rotate through the hand ball, and then drive the PCB milling cutter bar stock to rotate through the frictional force between the soft rubber ring and the handle, so that the cutting edge rotates along the axis of the handle. Whether the cutting edge and the handle are inclined can be judged according to the numerical jump of the dial indicator.

[0010] A fixed piece is fixed on the vertical slide rail. A support bolt is threadedly connected to the fixed piece, and a first fastening nut is threadedly connected to the support bolt, and the first fastening nut abuts against the fixed piece.

[0011] With the above structure, during use, when the operator pulls down the lifting frame, the lifting seat will abut against the upper end of the support bolt. When rotating the rotating wheel, the operator can continuously pull down the hand ball to keep the lifting seat abutting against the end of the support bolt, preventing the deformation of the soft rubber ring from affecting the height of the lifting frame and improving the accuracy of the detection result. Moreover, when the diameters of the PCB milling cutter bar stocks are different, the operator can adjust the height of the support bolt by rotating the support bolt and the first fastening nut to adapt to PCB milling cutter bar stocks with different diameters.

[0012] A magnetic block is fixed on the side end of the lifting seat, and the support bolt is made of iron material.

[0013] With the above structure, after the lifting seat contacts the support bolt, the magnetic block will generate a suction force with the support bolt, eliminating the need for the operator to apply a downward pressure through the hand ball, making the operation more convenient.

[0014] A notch is opened on the V-shaped channel steel, and the notch is aligned with the rotating wheel.

[0015] With the above structure, during use, when the PCB milling cutter bar stock is relatively thin, the rotating wheel can still descend into the notch to contact the PCB milling cutter bar stock, expanding the application range of the device.

[0016] An end cover is fixed at one end of the V-shaped channel steel away from the dial indicator. A positioning bolt is threadedly connected to the end cover, and a second fastening nut is threadedly connected to the positioning bolt, and the second fastening nut abuts against the end cover.

[0017] With the above structure, during use, when the operator places the PCB milling cutter bar stock, the end of the handle can be abutted against the end of the positioning bolt, directly positioning the position of the handle without the need for the operator to adjust, making the use more convenient. Moreover, according to the different lengths of the handle, the operator can rotate the second fastening nut and the positioning bolt to adjust the position of the positioning bolt to adapt to PCB milling cutter bar stocks of different models, expanding the application range of the device.

[0018] Compared with the prior art, the welding detection device for PCB milling cutter production has the following advantages:

[0019] 1. Through the V-shaped channel steel, rotating wheel, lifting frame and micrometer, the cutting edge of the PCB milling cutter blank can be driven to rotate along the axis of the shank. According to the change of the micrometer reading, it can be judged whether the cutting edge and the shank are inclined. No precision electronic instruments are required, the detection cost is low, and it is convenient to use.

[0020] 2. Through the support bolt and magnetic block, the position of the lifting seat can be fixed after it descends, preventing the deformation caused by the extrusion of the soft rubber ring from affecting the height of the lifting frame, thereby improving the accuracy of the detection result.

[0021] 3. Through the positioning bolt, the position of the shank of the PCB milling cutter blank can be limited, so that the operator can position it when placing the PCB milling cutter blank, without the need for further adjustment, improving the accuracy of the detection result and facilitating the operation of the operator.

At this time, the cutting edge is completely exposed from the V-shaped channel steel 11. Then, the operator pulls the lifting frame 5 downward by the hand knob 8 to stretch the tension spring 4. At this time, the lifting frame 5 drives the dial indicator 6 to descend synchronously. When the soft rubber ring 12 contacts the PCB bar, the probe of the dial indicator 6 abuts against the cutting edge. At this time, the lifting seat 3 abuts against the upper end of the support bolt 14, and the magnet 16 will adsorb to the upper end of the support bolt 14.
