[0002] Boring machines are key equipment in the field of machining, mainly used for machining high-precision hole systems, planes and complex shapes. They are widely used in aerospace, automobile manufacturing, precision molds, heavy machinery and other industries. As the core component of boring machines, the installation accuracy, stability and reliability of the boring spindle directly affect the machining accuracy and equipment life.

[0003] The boring bar is mounted on the base, and the milling cutter is mounted on the other end of the boring bar to process the workpiece.

[0004] Existing boring spindle mounting structures require the use of external tools to align the boring spindle onto the mounting base during installation, which is labor-intensive and cumbersome. Furthermore, the mounting base lacks the function of centering the boring spindle. Therefore, a new boring spindle mounting structure is proposed. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This utility model provides a boring bar mounting structure. It has the following advantages:

[0018] 1. The positioning mechanism first centers and fixes the boring bar, then installs it with bolts. The boring bar is placed against one side of the mounting base, with the mounting hole of the boring bar aligned with the mounting hole of the mounting base. The rotating ring is manually rotated, which drives the two connecting blocks to rotate. With the assistance of the corresponding arc-shaped connecting rod, the connecting blocks move the two sliders towards each other. Under the action of the two sliders, the boring bar is centered and stabilized on one side of the mounting base. After the boring bar is stabilized, it is fixed to one side of the mounting base with bolts. This mechanism centers and fixes the boring bar, making it easy to install on one side of the mounting base and preventing the center of the boring bar and the mounting base from not being in the same horizontal position.

[0019] 2. The limiting mechanism can fix the rotating ring when it stops rotating. Manually pull the limiting rod to pull out one end of the limiting rod that is inserted into the groove. At this time, the limiting rod drives the limiting ring to move inside the second fixed block and compresses the spring. After the rotating ring has rotated to a suitable number of turns, the tension applied to the limiting rod is released. Under the action of the spring, the limiting ring is pushed in the opposite direction. The limiting ring inserts one end of the limiting rod into the groove, which has the function of fixing the rotating ring and preventing the rotating ring from rotating in the opposite direction when there is no force.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a boring bar mounting structure, including a gearbox 1, a positioning mechanism 2 on one side of the gearbox 1, and a limit mechanism 3 at the bottom of the positioning mechanism 2.

[0030] Positioning mechanism 2 includes a rack 201 disposed inside the gearbox 1, a mounting base 208 mounted on one side of the rack 201, a boring bar 202 disposed on one side of the mounting base 208, sliders 205 symmetrically disposed on the outer surface of the mounting base 208, and a rotating ring 203 disposed on the outer surface of the rack 201.

[0031] Specifically, the rack 201 is connected to the inside of the gearbox 1 through the teeth at the top. The teeth can move the rack 201 laterally, thereby driving the boring bar 202 to move. Under the action of the two sliders 205, the boring bar 202 is fixed in the center on one side of the mounting base 208 so that the boring bar 202 can be installed on one side of the mounting base 208 by bolts.

[0032] The outer surface of the mounting base 208 is symmetrically equipped with a first fixing block 204, and a sliding groove 206 is provided on one side of the first fixing block 204.

[0033] Specifically, the two first fixing blocks 204 are slidably connected in the corresponding slide grooves 206. When the two sliders 205 move towards each other, they fix the boring spindle 202 in the center on one side of the mounting base 208, thus fixing the boring spindle 202 in the center.

[0034] Connecting blocks 209 are symmetrically installed on the outer surface of the rotating ring 203, and arc-shaped connecting rods 207 are provided inside the connecting blocks 209.

[0035] Specifically, the rotating ring 203 is rotatably connected to the outside of the toothed rod 201, and one end of the arc-shaped connecting rod 207 is rotatably connected to the inside of the connecting block 209. When the rotating ring 203 rotates, it can drive the connecting block 209 to rotate. Under the action of the arc-shaped connecting rod 207, the slider 205 is pushed outward inside the groove 206, and both sliders 205 are pushed outward at the same time.

[0036] The slider 205 is slidably connected inside the groove 206, and the other end of the arc-shaped connecting rod 207 is rotatably connected to one side of the slider 205.

[0037] Specifically, the slider 205 slides inside the groove 206 under the force of the arc-shaped connecting rod 207, fixing the fixed ends of the boring spindles 202 of different sizes in the center, and the mounting holes of the fixed ends of the boring spindles 202 need to match the mounting holes of the mounting base 208.

[0038] Furthermore, the boring bar 202 is first placed on one side of the mounting base 208. The rotating ring 203 is manually rotated, and the rotating ring 203 drives the two connecting blocks 209 to rotate simultaneously. The connecting blocks 209, with the assistance of the arc-shaped connecting rod 207, cause the other end of the arc-shaped connecting rod 207 to drive the slider 205 to move in the slide groove 206. At this time, the two sliders 205 move towards each other at the same time, fixing the boring bar 202 in the center on one side of the mounting base 208. Finally, the boring bar 202 is fixed to one side of the mounting base 208 with bolts.

[0039] Example 2

[0040] Reference Figure 4 and Figure 5This is the second embodiment of the present invention, which is based on the previous embodiment and includes a limiting mechanism 3 for restricting the rotation of the rotating ring 203.

[0041] The limiting mechanism 3 includes a second fixing block 301 fixedly installed at the bottom of the toothed bar 201. A limiting rod 302 is provided inside the second fixing block 301. Several grooves 303 are evenly distributed on one side of the rotating ring 203.

[0042] Specifically, the limiting rod 302 is slidably connected inside the second fixed block 301, and one end of the limiting rod 302 is movably inserted into the inside of the groove 303. After the rotating ring 203 stops rotating, the limiting rod 302 is inserted into the groove 303 to restrict the rotation of the rotating ring 203.

[0043] A limit ring 304 is installed on the outer surface of the limit rod 302, and a spring 305 is provided on one side of the limit ring 304.

[0044] Specifically, the limiting ring 304 is fixedly sleeved on the outside of the limiting rod 302, and one side of the limiting ring 304 is pushed to contact the second fixing block 301 by the force of the spring 305. The limiting ring 304 pushes the limiting rod 302 into the groove 303 to prevent the limiting rod 302 from moving in the opposite direction without force.

[0045] Spring 305 is located outside the limiting rod 302, and limiting ring 304 is slidably connected inside the second fixing block 301.

[0046] Specifically, the other end of the spring 305 is fixedly connected to the second fixing block 301. Under the action of the second fixing block 301 and the limiting ring 304, the spring 305 can be compressed. At the same time, under the action of the second fixing block 301, the limiting ring 304 can be pushed towards the groove 303.

[0047] Furthermore, manually pull the limiting rod 302 outward. The limiting rod 302 drives the limiting ring 304 to compress and deform the spring 305. At this time, one end of the limiting rod 302 inserted into the groove 303 moves out. Manually rotate the rotating ring 203. After the rotating ring 203 stops rotating, remove the pulling force applied to the limiting rod 302. At this time, under the action of the spring 305, the limiting ring 304 is pushed in the opposite direction. The limiting ring 304 drives one end of the limiting rod 302 to insert into the groove 303, thus restricting the rotation of the rotating ring 203.

[0048] Working principle: The gearbox 1 is equipped with a mechanism that enables the rack 201 to extend and retract, which is the same as that disclosed in the prior art. Manually pulling the limiting rod 302 outward causes the limiting ring 304 to compress the spring 305. Pulling out one end of the limiting rod 302 from the groove 303 allows manual rotation of the rotating ring 203, which in turn causes the two connecting blocks 209 to rotate simultaneously. Under the action of the corresponding arc-shaped connecting rod 207, the connecting blocks 209 push the slider 205 to its maximum position in the slide groove 206. At this point, the boring bar 202 is placed against one side of the mounting base 208. Reversing the rotating ring 203, the same principle applies, and the sliders 205 are engaged on both sides of the boring bar 202. The two sliders 205 then engage the boring bar... 202 is fixed in place. At this time, the rotating ring 203 stops rotating, and the tension applied to the limiting rod 302 is released. Under the action of the spring 305, the spring 305 pushes the limiting ring 304 in the opposite direction. The limiting ring 304 inserts one end of the limiting rod 302 back into the groove 303, restricting the rotation of the rotating ring 203, thereby restricting the movement of the two sliders 205 in the slide groove 206. After the boring spindle 202 is centered and stabilized on one side of the mounting base 208, the boring spindle 202 and the mounting base 208 are fixed with bolts. After it is completely fixed, the milling cutter to be used for machining is installed at the end of the boring spindle 202. By controlling the movement of the rack 201, the rack 201 drives the boring spindle 202 to extend and retract, and the workpiece can be machined.
