[0001] The invention relates to a machining adjustment tool, in particular to an external rotation adjustment tool. Background Art

[0002] As shown in the Chinese invention patent CN203044929U direct pressure single-edge fine-tuning boring tool, the existing boring tools usually use the following method to fine-tune the blade: loosen the locking screw, drive the fine-tuning screw to rotate through the dial, the fine-tuning screw then drives the blade to slide to achieve fine-tuning, and finally tighten the locking screw.

[0003] The defects are: 1. The adjustment accuracy of this adjustment method is limited and cannot meet the user's requirements for extremely small fine-tuning; 2. The operation process of this adjustment method is relatively cumbersome and requires repeated rotation of the locking screw, so further improvement is needed. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the above-mentioned background technology and to provide an externally rotating adjustable tool, which should be easy to adjust and capable of achieving extremely small fine-tuning.

[0005] The technical solution of the present invention is:

[0006] An external rotation adjustment tool comprises a tool body, a blade and a tool holder adjustment mechanism; the feature is that it also comprises an external rotation adjustment mechanism for performing extremely fine adjustments on the tool holder adjustment mechanism;

[0007] The external rotation adjustment mechanism includes an outer ring and a transmission member rotatably positioned on the knife body, and a tooth block and a slider slidably positioned on the knife body; the outer ring, the transmission member, the tooth block and the slider are meshed in sequence; the blade is installed on the slider through the knife seat adjustment mechanism.

[0008] The rotation axis of the outer ring is coaxial with the axis of the cutter body; the rotation axis of the outer ring, the rotation axis of the transmission member, and the sliding axis of the slider are perpendicular to each other.

[0009] In the external rotation adjustment mechanism, the outer ring is rotatably positioned outside the cutter body, and the outer ring is provided with end face teeth; the transmission member comprises a coaxially connected gear and a lead screw, and the gear is meshed with the end face teeth.

[0010] The tooth block is provided with screw holes and tooth block bevel teeth, and the screw rod is meshed with the screw holes; the slider is provided with slider bevel teeth, and the slider bevel teeth are meshed with the tooth block bevel teeth.

[0011] The tooth pitch of the end face teeth gradually increases from the middle to both sides.

[0012] The outer circumferential surface of the outer ring is provided with anti-slip grooves.

[0013] In the knife seat adjustment mechanism, the knife seat and the stop block can be slidably positioned in the sliding hole of the sliding block and are engaged with the adjustment screw at the same time.

[0014] The tool holder adjustment mechanism also includes a first positioning pin and a positioning groove for limiting the axial movement of the adjustment screw and a second positioning pin and a limiting groove for controlling the axial movement of the stop block.

[0015] The knife seat adjustment mechanism also includes a locking screw for locking the knife seat.

[0016] The beneficial effects of the present invention are:

[0017] The present invention adds an external rotation adjustment mechanism to the knife body, and the blade can be finely adjusted by directly rotating the outer ring of the external rotation adjustment mechanism.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] like Figure 1 As shown, an external rotation adjustment tool comprises a tool body 1, a blade 2, an external rotation adjustment mechanism, and a blade holder adjustment mechanism. The blade holder adjustment mechanism is used for large-range adjustment of the blade, and the external rotation adjustment mechanism is used for extremely fine adjustment of the blade.

[0035] The external rotation adjustment mechanism includes an outer ring 3, a transmission member 4, a tooth block 5 and a slider 6. When the position of the blade needs to be adjusted very finely, the outer ring is rotated first, and the outer ring then drives the transmission member, the tooth block and the slider to move in sequence, thereby driving the blade holder adjustment mechanism with the blade to move, so as to achieve very fine adjustment.

[0036] The outer ring and the transmission member are rotatably positioned on the cutter body, and the tooth block and the slider are slidably positioned on the cutter body. The rotation axis of the outer ring, the rotation axis of the transmission member, and the sliding axis of the slider are perpendicular to each other. The rotation axis of the transmission member is parallel to the sliding axis of the tooth block.

[0037] The outer ring is rotatably positioned outside the cutter body, the rotation axis of the outer ring is coaxial with the cutter body axis, the side of the outer ring facing the blade is provided with end teeth 3-1, and the outer circumferential surface of the outer ring is provided with anti-slip grooves 3-2.

[0038] The transmission member is rotatably positioned inside the cutter body, and the rotation axis of the transmission member is perpendicular to the rotation axis of the outer ring. The transmission member includes a coaxially connected gear 4-1 and a screw rod 4-2, and the gear is meshed with the end face teeth. Figure 7As shown, the pitch of the face teeth gradually increases from the middle to both sides, so each spur tooth of the gear can mesh with the face teeth on both sides at the same time.

[0039] The tooth block and the slider can be slidably positioned inside the cutter body. The sliding axis of the tooth block is parallel to the rotation axis of the transmission member. The tooth block is provided with a screw hole 5-1 and a tooth block bevel tooth 5-2. The external thread of the screw rod is meshed with the internal thread of the screw hole. Since the screw rod has a self-locking property, the screw rod can drive the tooth block to move, but the tooth block cannot drive the screw rod to move in the reverse direction. The bevel tooth of the tooth block is arranged on the side of the tooth block facing the blade.

[0040] The sliding axis of the slider is perpendicular to the rotation axis of the transmission member. The side of the slider facing the gear block is provided with slider bevel teeth 6-1, and the slider bevel teeth are meshed with the gear block bevel teeth.

[0041] The blade is mounted on the slide block through a knife seat adjustment mechanism. In the knife seat adjustment mechanism, the slide block is provided with an axially penetrating sliding hole, which includes a front sliding hole 6-2 and a rear sliding hole 6-3. The cross section of the front sliding hole is rectangular, and the knife seat 7 can be slidably positioned in the front sliding hole. The cross section of the knife seat is also rectangular. The stop block 8 can be slidably positioned in the rear sliding hole. The sliding hole is also provided with an adjustment screw 9, which passes through the stop block and then extends into the knife seat. The knife seat, the stop block, and the adjustment screw are coaxially arranged.

[0042] like Fig.12 As shown, the right end face of the adjusting screw is provided with a hexagonal hole 9-1, the middle part of the adjusting screw is provided with an annular positioning groove 9-2, both sides of the adjusting screw are provided with adjusting threads, the tool holder is provided with a tool holder screw hole matching with the left adjusting thread, and the backstop block is provided with a backstop block screw hole matching with the right adjusting thread.

[0043] like Fig.12 As shown, two first positioning pins 11 perpendicular to the adjusting screw extend into the slide hole and pass through the upper and lower sides of the adjusting screw respectively. The first positioning pins 11 are also embedded in the positioning groove to prevent the adjusting screw from moving axially ( Fig.12 horizontal direction). Fig.13 As shown, a limit groove 8-1 is provided on the side of the stop block, and a second positioning pin 12 extends into the slide hole and the limit groove to control the axial movement distance of the stop block ( Fig.13 horizontal direction).

[0044] The slide block is also provided with a locking screw 10 for locking the knife seat.

[0045] The working principle of the present invention is that the tool holder adjustment mechanism is used for large-range adjustment in order to quickly approach the processing size, and the outward rotation adjustment mechanism is used for extremely small fine adjustment in order to accurately adjust the processing size.

[0046] The working steps of the present invention are as follows:

[0047] 1. Use the knife seat adjustment mechanism for wide range adjustment

[0048] The total stroke of the blade for the ultra-fine adjustment of the external rotation adjustment mechanism is only 0.08mm (two turns of the outer ring), so first quickly approach the pre-processing size through the tool holder adjustment mechanism, and then use the external rotation adjustment mechanism for ultra-fine adjustment;

[0049] The adjustment method of the tool holder adjustment mechanism is: loosen the locking screw, use a tool to insert the hexagonal hole to turn the adjusting screw, the adjusting screw drives the tool holder and the stop block to move at the same time, quickly adjust the blade position (quickly approach the pre-processing size), and then tighten the locking screw; the blade moves 0.8mm when the adjusting screw is rotated one circle;

[0050] 2. Use the external rotation adjustment mechanism for very small adjustments

[0051] Rotate the outer ring, the outer ring drives the gear of the transmission part to rotate, the lead screw of the transmission part drives the tooth block to move, and the tooth block drives the slider to move, so as to achieve extremely small fine-tuning of the blade; when the outer ring rotates one grid (a circle has 40 grids), the blade moves 0.001mm (processing diameter 0.002mm), when the outer ring rotates one circle, the blade moves 0.04mm (processing diameter 0.08mm), when the outer ring rotates at most two circles, the blade moves 0.08m (processing diameter 0.16mm), which can achieve extremely small fine-tuning;

[0052] The traditional dial rotates one grid (a circle has 50 grids) and the blade moves 0.005mm (processing diameter 0.01mm).

[0053] The preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
