Technical Field

[0001] This utility model relates to the field of tool mounting technology, and in particular to an auxiliary mounting mechanism for reamers. Background Technology

[0002] Tool floating refers to the installation and adjustment of a tool on a machine tool to give it a certain "floating" ability during machining. This floating ability allows the tool to flexibly adjust its position to adapt to the irregularities of the workpiece surface, thereby improving machining accuracy and efficiency.

[0003] A search revealed Chinese patent publication number CN219336944U, which discloses a mini floating tool. This patent uses a floating part between the tool holder and the clamping part, allowing the tool holder and the clamping part to move relative to each other to achieve a floating effect, thereby improving the machining accuracy of the hole. However, this device has certain problems: it cannot adjust the floating amount of the tool according to different types of machining needs, which will increase the friction between the tool and the workpiece, resulting in tool wear. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary installation mechanism for reamers in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

An adjusting cylinder is coaxially fixed to the bottom of the connecting tube, a floating plate is slidably connected inside the adjusting cylinder, and an adjusting spring is fixedly connected to the top of the floating plate. The adjusting spring is fixedly connected to the top wall of the adjusting cylinder. A clamping mechanism is provided at the bottom of the floating plate, and an adjusting mechanism is provided inside the adjusting cylinder. The adjusting mechanism is used to change the sliding distance of the floating plate within the adjusting cylinder. The adjusting mechanism includes two auxiliary blocks, which are fixedly connected to the inner wall of the adjusting cylinder. The two auxiliary blocks are radially symmetrical along the adjusting cylinder and slidably connected to the floating plate.

[0007] Preferably, the threaded connection assembly includes a retaining ring, which is fixedly connected to the bottom of the tapered shank, and the inner wall of the retaining ring is threadedly connected to the connecting pipe.

[0008] Preferably, the clamping mechanism includes a connecting cylinder, which is fixedly connected to the bottom of the floating plate and slidably connected to the lower end of the adjusting cylinder.

Therefore, they should not be construed as limitations on this utility model.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-5As shown, an auxiliary mounting mechanism for a reamer includes a tapered shank 101, a connecting pipe 201 below the tapered shank 101, and a threaded connection between the connecting pipe 201 and the tapered shank 101. An adjusting cylinder 202 is coaxially fixed to the bottom of the connecting pipe 201, a floating plate 401 is slidably connected inside the adjusting cylinder 202, and an adjusting spring 402 is fixedly connected to the top of the floating plate 401. The adjusting spring 402 is fixedly connected to the top wall of the adjusting cylinder 202. A clamping mechanism is provided at the bottom of the floating plate 401, and an adjusting mechanism is provided inside the adjusting cylinder 202. The adjusting mechanism is used to change the sliding distance of the floating plate 401 within the adjusting cylinder 202. The adjusting mechanism includes two auxiliary blocks 301, which are fixedly connected to the inner wall of the adjusting cylinder 202. The two auxiliary blocks 301 are radially symmetrical along the adjusting cylinder 202 and slidably connected to the floating plate 401. Each of the auxiliary blocks 301 has a sliding groove 302 extending through it. A sliding plate 303 is provided in the sliding groove 302. The sliding plate 303 is slidably connected to the top of the adjusting cylinder 202. Each sliding plate 303 has a limit block 304 fixedly connected to its bottom. The limit block 304 is slidably connected to the sliding groove 302. The sliding plate 303 has multiple limit holes. Bolts 305 are threaded into the limit holes. The bolts 305 are threaded onto the outer wall of the connecting pipe 201. Rotating the bolts 305 causes them to disengage from the limit holes, and then the sliding plate 303 slides against the adjusting cylinder 202. Adjusting the position of the limit holes causes the limit block 304 to slide within the sliding groove 302, changing the distance between the limit block 304 and the bottom wall of the adjusting cylinder 202. This allows the floating plate 401 to abut against the limit block 304 at a suitable position when it floats upward, thereby limiting the floating amount of the floating plate 401.

[0025] The threaded connection assembly includes a retaining ring 102, which is fixedly connected to the bottom of the tapered shank 101. The inner wall of the retaining ring 102 is threadedly connected to the connecting pipe 201. The connecting pipe 201 is fixed to the bottom of the tapered shank 101 by the threaded engagement between the retaining ring 102 and the connecting pipe 201.

[0026] The clamping mechanism includes a connecting cylinder 403, which is fixedly connected to the bottom of the floating plate 401. The connecting cylinder 403 is slidably connected to the lower end of the adjusting cylinder 202. The connecting cylinder 403 slides with the bottom of the adjusting cylinder 202, causing the floating plate 401 to move inside the adjusting cylinder 202, which in turn causes the adjusting spring 402 to compress and deform.

[0027] The bottom inner wall of the connecting cylinder 403 is provided with a conical wall 501, and a collet 502 is provided inside the conical wall 501, which abuts against the conical wall 501.

[0028] A sleeve 601 is provided below the collet 502. The inner wall of the sleeve 601 is provided with a threaded groove 602. The bottom of the connecting cylinder 403 is provided with a threaded joint 603. The threaded groove 602 and the threaded joint 603 are threadedly engaged, so that the collet 502 abuts against the conical wall 501. The collet 502 uses elastic deformation to clamp and fix the reamer.

[0029] A tapered cylinder 7 with its small end facing downwards is fixedly connected to the inner bottom wall of the sleeve 601. The end of the sleeve 601 away from the collet 502 has an inlet hole. The tapered cylinder 7 abuts against the end of the collet 502 away from the tapered wall 501.

[0030] Working principle: During use, the collet 502 is placed on the tool holder, then the tool holder is inserted into the feed hole, and the tool holder abuts against the floating plate 401. At this time, the collet 502 abuts against the tapered wall 501. Then, the threaded groove 602 and the threaded connector 603 engage, causing the tapered cylinder 7 to abut against the end of the collet 502 away from the tapered wall 501. The collet 502 uses elastic deformation to clamp and fix the reamer. Then, the connecting pipe 201 is fixed to the bottom of the tapered shank 101 by the threaded engagement of the retaining ring 102. Afterwards, the tool holder hole of the machine tool is cleaned and inspected, and then the tapered shank 101 is fixed in the tool holder hole by the nut. Adjustments can be made according to different types of tools. When adjusting the floating amount of the cutting tool, rotate bolt 305 to disengage it from the limiting hole. Then, slide the sliding plate 303 against the adjusting cylinder 202, adjust the position of the limiting hole, and let the limiting block 304 slide within the sliding groove 302. Change the distance between the limiting block 304 and the bottom wall of the adjusting cylinder 202 so that when the floating plate 401 floats upward, it abuts against the limiting block 304 at a suitable position, thereby limiting the floating amount of the floating plate 401 and making the machining process more stable. When the reamer is working, drive the connecting cylinder 403 to slide against the bottom of the adjusting cylinder 202, causing the floating plate 401 to move axially along the adjusting cylinder 202, and compressing the adjusting spring 402.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that 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.
