Description

Technical Field

[0001] This utility model relates to the field of boring bar holder technology, specifically an angle-adjustable boring bar holder. Background Technology

[0002] Double-head boring is a boring machining method that uses a boring machine or boring device with two boring heads to machine a workpiece. These two boring heads can simultaneously perform boring operations from both ends of the workpiece hole. When machining the inner hole of a large-diameter sleeve-type part, double-head boring can effectively reduce vibration and machining errors caused by an excessively large length-to-diameter ratio of the boring bar.

[0003] During boring, different machining requirements can be met by changing the angle of the boring bar, such as machining internal holes with different tapers or fine-tuning the cylindricity of the hole. Currently, with double-head boring machines, adjusting the boring bar angle requires adjusting each of the two boring bars individually, which is quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide an angle-adjustable boring bar holder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle-adjustable boring bar holder, comprising: a mounting base, and further comprising: a mounting opening on one side of the outer wall of the mounting base, a driving component mounted on one side of the inner wall of the mounting opening, and transmission components mounted at both ends of the bottom inner wall of the mounting opening, mounting brackets mounted on both sides of the outer walls of the mounting base, and adjustment components rotatably mounted on the outer walls of both mounting brackets, boring bars mounted at the bottom of both adjustment components, and a limit component mounted on the top inner wall of the mounting base.

[0006] The drive assembly includes a connecting plate, a drive shaft rotatably mounted on the top outer wall of the connecting plate, and a drive bevel gear mounted on the bottom of the drive shaft.

[0007] The transmission assembly includes a support plate, a worm gear rotatably mounted on one side of the outer wall of the support plate, and a driven bevel gear mounted on one end of the worm gear.

[0008] The adjustment assembly includes a rotating rod, a worm gear mounted on the outer wall of the rotating rod, a base mounted on the bottom outer wall of the rotating rod, and a chuck mounted on the bottom outer wall of the base.

[0009] A pointer is installed at one end of the outer wall of the rotating rod, and an angle gauge may be installed on the outer wall of the mounting bracket.

[0010] The limiting component includes a threaded rod, an internally threaded tube screwed onto the threaded rod, and multiple convex plates evenly distributed on the outer wall of the internally threaded tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model features an angle-adjustable boring bar holder. With two boring bars, it can perform double-head boring. When machining internal holes with different tapers, the drive assembly can be rotated, which in turn drives the two transmission assemblies to rotate in opposite directions, thereby driving the two adjustment assemblies to rotate in opposite directions. This allows for convenient adjustment of the angles of the two boring bars. After adjustment, the drive assembly can be fixed by a limiting assembly to prevent rotation of the drive assembly during boring. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5The adjustable boring bar holder provided by this utility model includes: a mounting base 1, and a mounting opening 2 on one side of the outer wall of the mounting base 1. A drive assembly 3 is installed on the inner wall of one side of the mounting opening 2, and transmission assemblies 4 are installed at both ends of the bottom inner wall of the mounting opening 2. Mounting brackets 5 are installed on both sides of the outer wall of the mounting base 1, and adjustment assemblies 6 are rotatably installed on the outer walls of the two mounting brackets 5. A boring bar 9 is installed at the bottom of the two adjustment assemblies 6, and a limit assembly 7 is installed on the top inner wall of the mounting base 1.

[0021] It should be noted that the two boring tools 9 can perform double-head boring. When machining internal holes with different tapers, the drive component 3 can be rotated, which in turn drives the two transmission components 4 to rotate in opposite directions, thereby driving the two adjustment components 6 to rotate in opposite directions. This allows for convenient adjustment of the angles of the two boring tools 9. After adjustment, the drive component 3 can be fixed by the limiting component 7 to prevent the drive component 3 from rotating during boring.

[0022] In a preferred embodiment, the drive assembly 3 includes a connecting plate 301, a drive shaft 302 rotatably mounted on the top outer wall of the connecting plate 301, and a drive bevel gear 303 mounted on the bottom of the drive shaft 302.

[0023] It should be noted here that the drive shaft 302 is rotatable, which in turn drives the active bevel gear 303 to rotate.

[0024] In a preferred embodiment, the transmission assembly 4 includes a support plate 401, a worm gear 402 rotatably mounted on one side of the outer wall of the support plate 401, and a driven bevel gear 403 mounted on one end of the worm gear 402.

[0025] It should be noted that the rotation of the active bevel gear 303 can drive the two driven bevel gears 403 to rotate in the opposite direction, which in turn drives the two worm gears 402 to rotate in the opposite direction.

[0026] In a preferred embodiment, the adjustment assembly 6 includes a rotating rod 601, a worm gear 602 mounted on the outer wall of the rotating rod 601, a base 603 mounted on the bottom outer wall of the rotating rod 601, and a chuck 604 mounted on the bottom outer wall of the base 603.

[0027] It should be noted here that: the two worm gears 402 rotate in opposite directions, which can drive the two worm wheels 602 to rotate in opposite directions, which in turn drive the two rotating rods 601 to rotate in opposite directions, which in turn drive the two boring tools 9 to rotate in opposite directions, while adjusting the angle of the two boring tools 9.

[0028] In a preferred embodiment, a pointer 605 is installed at one end of the outer wall of the rotating rod 601, and an angle gauge 8 may be installed on the outer wall of the mounting bracket 5.

[0029] It should be noted that rotating the lever 601 can drive the pointer 605 to rotate. By observing the position of the pointer 605 on the angle table 8, the adjustment angle of the boring tool 9 can be determined.

[0030] In a preferred embodiment, the limiting component 7 includes a threaded rod 701, an internally threaded tube 702 screwed onto the threaded rod 701, and a plurality of equidistantly distributed protrusions 703 fixed to the outer wall of the internally threaded tube 702.

[0031] It should be noted that the protruding plate 703 can be squeezed by hand, and the internal threaded tube 702 can be rotated to drive the internal threaded tube 702 to descend and press against the top of the drive shaft 302, thereby limiting the drive shaft 302.

[0032] Working principle: Two chucks 604 can respectively fix two boring tools 9. Double boring can be performed by the two boring tools 9. When it is necessary to machine internal holes with different tapers, the drive shaft 302 can be rotated to drive the active bevel gear 303 to rotate, which in turn drives the two driven bevel gears 403 to rotate in the opposite direction, which in turn drives the two worm gears 402 to rotate in the opposite direction, which in turn drives the two worm wheels 602 to rotate in the opposite direction, which in turn drives the two rotating rods 601 to rotate in the opposite direction, which in turn drives the two boring tools 9 to rotate in the opposite direction. The angle of the two boring tools 9 can be adjusted at the same time, which is more convenient. After adjustment, the convex plate 703 can be squeezed by hand to rotate the internal thread tube 702, which causes the internal thread tube 702 to descend and press against the top of the drive shaft 302, limiting the drive shaft 302 and preventing the drive shaft 302 from rotating during boring.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
