Abstract
Description
Technical Field
[0001] This utility model relates to the field of machinery, specifically a boring machine, and more specifically a tool setting device for a boring machine. Background Technology
[0002] When boring a hole, the boring machine needs to rough bore the inner hole and finish bore the inner hole. After rough boring the inner hole, the tool needs to be moved radially by an accurate distance for finish boring. In the past, the tool was hammered by hand and then test cut was performed. Sometimes too much hammering and sometimes too little hammering was very inaccurate, which affected work efficiency and increased production costs. Utility Model Content
[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a tool setting device for a boring machine, including a boring bar, a boring bar installed in the boring hole of the boring bar, and a boring bar fixing bolt installed above the boring bar; including a magnetic base, one side of the magnetic base is provided with an arc surface similar to that of the boring bar, and the other side is fixedly connected to a lower adjusting base, the lower adjusting base is provided with a strip-shaped slot, and the lower adjusting base is fixed to the lower adjusting base by bolts and the strip-shaped slot; a micrometer is fixed on the upper adjusting base; both the upper and lower adjusting bases are "T" shaped structures.
[0004] The magnetic base is fixed to the base via a support rod, and the base is fixed to the working surface of the boring machine.
[0005] The lower adjustment seat is provided with a through hole with a groove, and the fixing screw passes through the through hole to fix the lower adjustment seat to the side of the magnetic seat.
[0006] The support rod is a two-section sleeve structure, and the sleeve part is threaded.
[0007] The advantages of this utility model are: accurate positioning, which can reduce the number of trial cuts; improved work efficiency; improved product quality and reduced product defect rate; shortened product production cycle and reduced cost. Attached Figure Description

[0010] Figure 3 This is a schematic diagram showing the positional relationship between the magnetic base and the boring bar axis. Detailed Implementation
[0011] The present invention will now be described in detail with reference to the accompanying drawings. As shown in the drawings, the present invention includes a boring bar shaft 5, a boring bar 4 disposed in the boring bar hole 501 of the boring bar shaft, and a boring bar fixing bolt 7 disposed above the boring bar 4; one side of the magnetic base 6 is provided with an arc surface 601 similar to that of the boring bar shaft, and the other side is fixedly connected to the lower adjusting base 2. The lower adjusting base 2 is provided with a strip-shaped slot hole 201, and the upper adjusting base 3 is fixed to the lower adjusting base 2 below by bolts 8 and the strip-shaped slot hole 201; the relative positions of the upper adjusting base 3 and the lower adjusting base 2 can be set according to different products.
[0012] The micrometer 1 is fixed to the upper adjustment seat 3 by a micrometer fixing screw 11; both the upper adjustment seat 3 and the lower adjustment seat 2 are "T" shaped structures.
[0013] To ensure that the vertical position of the magnetic base remains unchanged, the magnetic base 6 is fixed to the base by a support rod 10, and the base is fixed to the working surface of the boring machine.
[0014] To prevent scratching the operator, the lower adjustment seat is provided with a through hole with a groove, and the fixing screw 9 passes through the through hole to fix the lower adjustment seat to the side of the magnetic base.
[0015] To accommodate different height requirements, the support rod is a two-section sleeve structure, with the sleeve section having threads.
[0016] The method of using this utility model is as follows: After rough boring is completed, the magnetic base is pressed tightly against the boring bar shaft. After the micrometer is adjusted to the predetermined size, the boring bar fixing bolt is loosened, and the boring bar is pushed from the back of the boring bar so that the boring bar abuts against the front end of the micrometer. Then the boring bar fixing bolt is tightened. In this way, the extension distance of the boring bar can be accurately positioned, and then fine boring can be performed.
