[0002] Internal chamfering equipment for stainless steel parts is a mechanical device specifically designed to chamfer the inner edges of stainless steel parts. It utilizes various processing principles, such as cutting with rotary tools, grinding with abrasives, or special processing methods, to machine the sharp inner edges of stainless steel parts into bevels or arcs with specific angles and dimensions. This satisfies the requirements of stainless steel parts in terms of assembly accuracy, strength, corrosion resistance, and hydrodynamics. Furthermore, depending on different production scales, part specifications, and processing accuracy requirements, various types and structures of equipment are available to achieve efficient and high-precision internal chamfering.

[0003] The most common internal chamfering equipment uses a rotary drive device to drive a tapered milling cutter to rotate at high speed for internal chamfering. It is suitable for tubular stainless steel parts. However, the equipment has defects in chamfering: when the equipment is in production line processing, the milling cutter is in contact with the part for a long time, which causes friction and heat generation, affecting its service life. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an internal chamfering processing equipment for stainless steel parts, so as to solve the problem that the chamfering milling cutter generates heat due to friction during long-term operation, which affects the service life of traditional chamfering equipment in the background art.

[0005] This utility model provides the following technical solution: an internal chamfering processing device for stainless steel parts, including a guide rail, a slide block slidably sleeved on the guide rail, a telescopic rotating column assembly rotatably sleeved inside the slide block, a chamfering tool fixedly installed at one end of the telescopic rotating column assembly, a motor fixedly installed on the outer wall of the slide block, and the output end of the motor fixedly installed at the other end of the telescopic rotating column assembly.

[0006] Furthermore, the telescopic rotating column assembly has a transverse groove on its side wall, the slide block has an oil reservoir on its inner wall, and the slide block has an oil inlet that communicates with the oil reservoir on its side wall.

[0007] Furthermore, the telescopic rotating column assembly includes an outer cylinder with a through-hole at one end, into which an inner cylinder is slidably fitted. A piston is fixedly connected to one end of the inner cylinder inserted into the inner cavity of the outer cylinder. A central partition ring is fixedly connected to the inner cavity of the outer cylinder. The central partition ring is connected to the piston via a spring. A flow hole is provided in the middle of the central partition ring and the piston. Several liquid holes are provided on the side wall of the outer cylinder. A slip ring is rotatably fitted on the side wall of the outer cylinder. A liquid inlet pipe is connected to the side wall of the slip ring. The liquid inlet pipe extends out of the slide block. The slip ring is fixedly connected to the inner wall of the slide block. A second one-way valve is installed inside the liquid inlet pipe. A first one-way valve is installed inside the inner cylinder.

[0008] Furthermore, the outer cylinder sidewall is provided with a convex ring, which is embedded in the slip ring. Both sides of the inner wall of the slip ring are fixedly connected with rubber sealing rings, and the two rubber sealing rings are in contact with the two sides of the rubber sealing ring respectively.

[0009] Furthermore, the inner cylinder sidewall is provided with several positioning protrusions, and the inner wall of the column hole of the outer cylinder is provided with several transverse grooves, and the several positioning protrusions of the inner cylinder are respectively slidably sleeved in the several transverse grooves.

[0020] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Reference Figure 1 and Figure 2 This utility model provides an internal chamfering processing device for stainless steel parts, including a guide rail 1, a slide block 2 slidably sleeved on the guide rail 1, a telescopic rotating column assembly 3 rotatably sleeved inside the slide block 2, a chamfering cutter 5 fixedly installed at one end of the telescopic rotating column assembly 3, a motor 4 fixedly installed on the outer wall of the slide block 2, and the output end of the motor 4 fixedly installed at the other end of the telescopic rotating column assembly 3. The telescopic rotating column assembly 3 is telescopic to pump liquid into the chamfering cutter 5.

[0022] In use, the inlet of the telescopic rotating column assembly 3 and the container for storing coolant can be connected through a hose. The motor 4 provides power to drive the telescopic rotating column assembly 3 to rotate at high speed in the slide 2. The telescopic rotating column assembly 3 drives the chamfering cutter 5 to rotate at high speed. As the slide 2 slides on the guide rail 1, the chamfering cutter 5 enters and exits the cavity of the tubular grinding part to perform internal chamfering. During this process, the chamfering cutter 5 will be subjected to the reverse thrust of the grinding part. In this way, the chamfering cutter 5 can press the telescopic rotating column assembly 3, thereby making the telescopic rotating column assembly 3 telescopic and pumping coolant. The coolant enters the chamfering cutter 5 for automatic cooling.

[0023] Reference Figure 2The telescopic rotating column assembly 3 has a transverse groove 7 on its side wall, the inner wall of the slide 2 is provided with an oil tank 6, and the side wall of the slide 2 is provided with an oil inlet 8 that communicates with the oil tank 6.

[0024] Lubricating oil can be introduced into the oil tank 6 through the oil inlet 8. When the telescopic rotating column assembly 3 rotates, its side wall comes into contact with the lubricating oil in the oil tank 6, which can achieve the lubrication effect. In addition, when the transverse groove 7 is aligned with the oil tank 6, the lubricating oil can enter the transverse groove 7. After the telescopic rotating column assembly 3 rotates, the lubricating oil in the transverse groove 7 can lubricate the inner wall of the slide block 2. By setting the transverse groove 7, it can be ensured that the lubricating oil is evenly distributed in the inner cavity of the slide block 2.

[0025] Reference Figure 3 The telescopic rotating column assembly 3 includes an outer cylinder 31, one end of which has a through-hole that extends into the inner cavity. An inner cylinder 32 is slidably fitted inside the through-hole. A piston 34 is fixedly connected to one end of the inner cylinder 32 that is inserted into the inner cavity of the outer cylinder 31. A partition ring plate 33 is fixedly connected to the inner cavity of the outer cylinder 31. The partition ring plate 33 is connected to the piston 34 via a spring 35. A flow hole is provided in the middle of the partition ring plate 33 and the piston 34. Several liquid holes 310 are provided on the side wall of the outer cylinder 31. A slip ring 36 is rotatably fitted on the side wall of the outer cylinder 31. An inlet pipe 37 is connected to the side wall of the slip ring 36. The inlet pipe 37 extends out of the outside of the slide seat 2. The slip ring 36 is fixedly connected to the inner wall of the slide seat 2. A second check valve 39 is installed inside the inlet pipe 37. A first check valve 38 is installed inside the inner cylinder 32.

[0026] When the inner cylinder 32 is under pressure, it retracts into the outer cylinder 31 and drives the piston 34 to slide. When there is coolant inside the outer cylinder 31, the coolant is squeezed and can flow into the inner cylinder 32 through the middle partition ring plate 33 and the flow hole of the piston 34. The coolant can be injected into the chamfering tool 5 after passing through the inner cylinder 32. When the inner cylinder 32 is not pushed, the piston 34 is reset under the elastic force of the spring 35, so that the inner cavity of the outer cylinder 31 forms a negative pressure. The coolant can be injected into the outer cylinder 31 through the hose connected by the liquid inlet pipe 37.

[0027] Reference Figure 3 The outer cylinder 31 has a protruding ring 311 on its side wall. The protruding ring 311 is embedded in the slip ring 36. Rubber sealing rings 312 are fixedly connected to both sides of the inner wall of the slip ring 36. The two rubber sealing rings 312 are in contact with the two sides of the rubber sealing ring 312 respectively.

[0028] This design ensures a tight seal between the slip ring 36 and the outer cylinder 31, preventing liquid from entering the slip ring 36 and leaking out of the outer cylinder 31.

[0029] Reference Figure 4 The inner cylinder 32 has several positioning protrusions on its side wall, and the outer cylinder 31 has several transverse grooves on its inner wall of the column hole. The positioning protrusions of the inner cylinder 32 are slidably sleeved in the several transverse grooves.

[0030] This setting ensures that the outer cylinder 31 and the inner cylinder 32 rotate synchronously, and ensures that the telescopic rotating column assembly 3 can transmit the rotational force of the motor 4.

[0031] Reference Figure 4 The piston 34 includes a main body plug 341, which is connected to a flange at one end of the inner cylinder 32. The side wall of the main body plug 341 has an annular groove, and a sealing ring 342 is fixedly connected in the annular groove. The sealing ring 342 fits against the inner wall of the outer cylinder 31.

[0032] By setting a sealing ring 342, the sealing performance of the piston 34 in the guide rail 1 is improved, and the coolant is prevented from leaking through the gap between the outer cylinder 31 and the inner cylinder 32.

[0033] Reference Figure 5 The chamfering tool 5 has a chip discharge hole 51 on its side wall, and a beveled hole 52 is provided at one end of the chamfering tool 5 facing the telescopic rotating column assembly 3. The other end of the beveled hole 52 is connected to the chip discharge hole 51.

[0034] When the chamfering tool 5 rotates at high speed to perform internal chamfering on the part, the chips can pass through the chip discharge hole 51 for chip removal, while the coolant output by the telescopic rotating column assembly 3 can flow out through the inclined hole 52. The liquid flows out through the chip discharge hole 51 and comes into contact with the part, thereby achieving a direct cooling effect.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. This utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
