Technical Field

[0001] The utility model relates to the technical field of machining tools, in particular to a bridge-type adjusting boring tool. Background Technique

[0002] When the bridge-type boring tool is in use, the position of the tool can be adjusted. However, when the operator moves the tool, simply pushing or pulling it by hand makes it difficult to accurately control the moving distance of the tool. Therefore, in order to solve the above technical problems, we propose a bridge-type adjusting boring tool. Content of the Utility Model

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a bridge-type adjusting boring tool.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A bridge-type adjusting boring tool, including a tool bridge main body and a plurality of tool heads. Installation cavities are provided inside both ends of the tool bridge main body. A threaded rod is rotatably installed inside the installation cavity. A sliding seat is installed inside the installation cavity through the threaded rod. The upper end of the sliding seat extends to the upper surface of the tool bridge main body. One end of the upper surface of the sliding seat away from the tool bridge main body is connected to the tool head by a screw. Corresponding to the sliding seat, matching stroke grooves are provided at both ends of the lower surface of the tool bridge main body, and a plurality of bolts are provided in the stroke grooves. The upper end of the bolt is connected to the sliding seat by a thread.

[0006] Preferably, an internal hexagonal block is provided at one end of the threaded rod close to the tool head, and the internal hexagonal block is located inside the end of the tool bridge main body.

[0007] Preferably, a pair of guide rods are provided inside the installation cavity, and the rod bodies of the guide rods are slidably connected with the sliding seat.

[0008] Preferably, a receiving groove is provided on the lower surface of the sliding seat, and a pair of limiting strips corresponding to the receiving groove are provided on the bottom surface of the installation cavity, and the limiting strips are located on both sides of the bolt.

[0009] Preferably, a slide rail is provided on the upper surface of the tool bridge main body, and matching slide grooves are provided on both sides of the lower surface of the sliding seat corresponding to the slide rail.

[0010] Preferably, scale lines are provided in the middle of the lower surface of the sliding seat, and a color coating for prompting is provided inside the scale lines.

[0011] Preferably, a lock washer is provided on the rod body at the lower end of the bolt, and an anti-slip pattern is provided on the lower surface of the stroke groove of the tool bridge main body.

[0012] The bridge-type adjusting boring tool proposed by the utility model has the following beneficial effects:

[0013] 1: In the present utility model, through the cooperation of the threaded rod and the sliding seat, when adjusting the distance between the cutting heads, the operator can complete the adjustment by rotating the threaded rod. The threaded rod drives the sliding seat to move horizontally through its own rotation. Therefore, compared with the traditional solution, the operator can more precisely control the moving distance of the cutting head, thus improving the accuracy of controlling the distance between the cutting heads. The setting of the scale lines enables the operator to conveniently judge the distance between the cutting heads. At the same time, the threaded rod can also initially fix the sliding seat to avoid the defect that the sliding seat is prone to self-movement when the operator fixes the sliding seat with bolts subsequently. That is, through the setting of the threaded rod and the sliding seat, the present solution solves the defect of low accuracy in adjusting the distance between the cutting heads caused by the operator simply pushing or pulling the cutting heads by hand in the traditional solution.

[0014] 2: The setting of the hexagon socket block in the present utility model facilitates the operator to rotate the threaded rod with an external wrench, making it more convenient and smooth for the operator to drive the threaded rod. The setting of the guide rod provides a certain guiding and limiting effect on the sliding seat, enabling the threaded rod to drive the sliding seat to move more conveniently and stably when rotating. The setting of the limiting strip further improves the stability of the threaded rod driving the sliding seat to move. The setting of the slide rail further improves the stability of the sliding seat when moving and maintains the stability of the sliding seat when processing external workpieces to prevent the cutting head from being unstable during use. The setting of the scale lines enables the operator to more easily, conveniently and accurately determine the distance between the cutting heads when adjusting the distance between the cutting heads. The setting of the color coating further improves the accuracy of the operator observing the scale lines. The setting of the lock washer makes the bolt not easy to loosen during use, that is, makes the sliding seat more likely to maintain stability during the use of the boring tool.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Embodiment 1

[0024] Refer to Figures 1-6 , a bridge-type adjustable boring tool, including a tool bridge body 1 and a plurality of tool heads 2. Installation cavities 3 are provided inside both ends of the tool bridge body 1. A threaded rod 4 is rotatably installed inside the installation cavity 3. A sliding seat 5 is installed inside the installation cavity 3 through the threaded rod 4. The upper end of the sliding seat 5 extends to the upper surface of the tool bridge body 1. One end of the upper surface of the sliding seat 5 away from the tool bridge body 1 is connected to the tool head 2 by a screw. Corresponding to the sliding seat 5 at both ends of the lower surface of the tool bridge body 1, there are matching travel grooves and a plurality of bolts 6 are provided in the travel grooves. The upper end of the bolt 6 is threadedly connected to the sliding seat 5.

[0025] Embodiment 2

[0026] Refer to Figures 1-6 , in the case where other parts are the same as those in Embodiment 1, the difference between this embodiment and Embodiment 1 is that:

[0027] An internal hexagonal block 7 is provided at one end of the threaded rod 4 close to the tool head 2. The internal hexagonal block 7 is located inside the end of the tool bridge body 1. The setting of the internal hexagonal block 7 facilitates personnel to rotate the threaded rod 4 with an external wrench, so that it is more convenient and smooth for personnel to drive the threaded rod 4; a pair of guide rods 8 are provided inside the installation cavity 3. The rod body of the guide rod 8 is slidably connected to the sliding seat 5. The setting of the guide rod 8 has a guiding and limiting effect on the sliding seat 5 to a certain extent, so that the sliding seat 5 can be driven to move more conveniently and stably when the threaded rod 4 rotates; a receiving groove is provided on the lower surface of the sliding seat 5. A pair of limit strips 9 are provided on the inner bottom surface of the installation cavity 3 corresponding to the receiving groove. The limit strips 9 are located on both sides of the bolt 6. The setting of the limit strips 9 further improves the stability of the threaded rod 4 driving the sliding seat 5 to move.

[0028] The upper surface of the tool bridge body 1 is provided with a slide rail 10. On both sides of the lower surface of the slide seat 5, chutes are correspondingly provided for mating with the slide rail 10. The setting of the slide rail 10 further improves the stability of the slide seat 5 during movement, and when machining external workpieces, the stability of the slide seat 5 is maintained to prevent the tool tip 2 from being unstable during use. In the middle of the lower surface of the slide seat 5, there is a scale pattern 12, and a color coating for prompting is provided inside the scale pattern 12. The setting of the scale pattern 12 facilitates personnel to more easily, conveniently and accurately determine the distance between the tool tips 2 when adjusting the distance between the tool tips 2, and the setting of the color coating further improves the accuracy of personnel observing the scale pattern. On the rod body at the lower end of the bolt 6, there is a lock washer 11. The lower surface of the travel groove of the tool bridge body 1 is provided with anti-slip lines. The setting of the lock washer 11 makes the bolt 6 not easy to loosen during use, that is, the slide seat 5 is more likely to maintain stability during the use of the boring tool.

[0029] Principle of use and advantages: During the use of the present utility model, the tool bridge body 1 is used to connect with an external machine tool. Then, when machining a workpiece is required, personnel install the tool tip 2 at the end of the slide seat 5 through screws, and then the tool bridge body 1 can drive the tool tip 2 to machine the external workpiece. Then, when it is necessary to adjust the distance between the tool tips 2 according to specific machining requirements, personnel rotate the threaded rod 4 according to the requirements. When the threaded rod 4 rotates, it drives the slide seat 5 to move. Thus, by the movement of the slide seat 5, the tool tip 2 can be driven to move, that is, the effect of adjusting the distance between the tool tips 2 is achieved.

[0030] At the same time, during the above process, since the lower side of the slide seat 5 is connected with a bolt 6, that is, after the position of the tool tip 2 is determined, the bolt 6 can be rotated, so that the end of the bolt 6 gradually contacts the lower surface of the travel groove through the lock washer 11 until the lower end of the bolt 6 is locked with the lower surface of the travel groove. At this time, the slide seat 5 realizes the final fixation, that is, it avoids the phenomenon that the slide seat 5 moves slowly due to vibration during the machining of the workpiece by the boring tool, resulting in inaccurate machining accuracy. To sum up, during the use of this solution, through the cooperation of the threaded rod 4 and the slide seat 5, when personnel adjust the distance between the tool tips 2, they can complete the adjustment by rotating the threaded rod 4. The threaded rod 4 pushes the slide seat 5 to move horizontally through its own rotation. Therefore, compared with the traditional solution, personnel can more finely control the moving distance of the tool tip 2, thereby improving the accuracy of controlling the distance between the tool tips 2. The setting of the scale pattern 12 enables personnel to conveniently judge the distance between the tool tips 2. At the same time, the threaded rod 4 can also play a preliminary fixing effect on the slide seat 5 to avoid the defect that the slide seat 5 is prone to move by itself when personnel fix the slide seat 5 with the bolt 6 subsequently. That is, through the setting of the threaded rod 4 and the slide seat 5 in this solution, the defect of low accuracy in adjusting the distance between the tool tips 2 caused by personnel simply pushing or pulling the tool tip 2 by hand in the traditional solution is solved.

[0031] It should be further noted that the setting of the hexagon socket block 7 facilitates the rotation of the threaded rod 4 by an external wrench, making it more convenient and smooth for personnel to drive the threaded rod 4; the setting of the guide rod 8 provides a certain guiding and limiting effect on the sliding seat 5, enabling the threaded rod 4 to drive the sliding seat 5 to move more conveniently and stably when rotating; the setting of the limiting strip 9 further improves the stability of the threaded rod 4 driving the sliding seat 5 to move; the setting of the slide rail 10 further improves the stability of the sliding seat 5 when moving, and maintains the stability of the sliding seat 5 when processing external workpieces to prevent the tool tip 2 from being unstable during use; the setting of the scale marks 12 facilitates personnel to more easily, conveniently and accurately determine the distance between the tool tips 2 when adjusting the distance between the tool tips 2, and the setting of the color coating further improves the accuracy of personnel observing the scale marks; the setting of the lock washer 11 makes the bolt 6 not easy to loosen during use, that is, makes the sliding seat 5 more likely to maintain stability during the use of the boring tool.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
