Description

Technical Field

[0001] This utility model relates to the field of reamer technology, specifically a double-edged high-speed forming reamer. Background Technology

[0002] A reamer is a rotary cutting tool with one or more cutting teeth used to remove a thin layer of metal from the surface of a machined hole. Reamers are rotary finishing tools with straight or spiral cutting edges, used for enlarging or repairing holes. Because of the small cutting volume, the machining accuracy requirements of reamers are usually higher than those of drill bits. They can be operated manually or mounted on a drilling machine.

[0003] In the field of metal cutting, traditional forming reamers generally adopt an integrated structure design of the cutter head and the cutter body. After the cutter head wears out, the overall scrap rate is as high as 70% to 80%. The cutter head cannot be replaced separately after it is damaged, and the reuse rate of the cutter body is low. In addition, the manual installation and replacement of reamers in the current technology is slow and requires a lot of time, which reduces the working efficiency of the reamer. Utility Model Content

[0004] The purpose of this invention is to provide a double-edged high-speed forming reamer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-edged high-speed forming reamer, comprising a mounting base, a blade body, and a cutting head. The cutting head has four symmetrically distributed slots. An adjusting rod is slidably installed inside the blade body. Four symmetrically distributed locking rods are arranged around the blade body and adjusting rods. Each of the four locking rods corresponds to a slot. The cutting head is movably engaged with the four locking rods through the slots. Each of the four locking rods has a first oil groove. A piston is sleeved on each of the four locking rods. Each piston is slidably connected to its corresponding locking rod through the first oil groove. Three annularly distributed slots are provided on the blade body. The mounting base has three annularly distributed adjusting blocks. Clamping rods are fixedly installed on each of the three adjusting blocks. The clamping rods are movably engaged with the blade body. Inserting rods are fixedly installed on each of the three clamping rods. The inserting rods are movably engaged with the blade body through the three slots.

[0006] As a further preferred embodiment of this technical solution, a first support rod and a second support rod are provided between the four sets of clamping rods, adjusting rods, and blades, and the first support rod and the second support rod are distributed in a cross pattern.

[0007] As a further preferred embodiment of this technical solution, the two ends of the first support rod are rotatably connected to the adjusting rod and the locking rod respectively via a rotating shaft, the left end of the second support rod is slidably connected to the locking rod, and the right end of the second support rod is rotatably connected to the blade via a rotating shaft.

[0008] As a further preferred embodiment of this technical solution, a push plate is slidably installed inside the blade, and all four sets of pistons are slidably connected to the push plate.

[0009] As a further preferred embodiment of this technical solution, each of the three sets of adjustment blocks is provided with a slider, and the mounting base is provided with three sets of sliding grooves corresponding to the adjustment blocks. The adjustment blocks are slidably connected to the mounting base through the sliders and sliding grooves.

[0010] As a further preferred embodiment of this technical solution, a turntable is rotatably mounted inside the mounting base. The turntable is rotatably connected to the mounting base via a rotating frame. A ring tooth is fixedly mounted on the turntable. All three sets of adjusting blocks are meshed with the turntable via the ring tooth. A toothed ring is sleeved on each of the three sets of rotating frames. A rack is slidably mounted inside the mounting base, and the rack is meshed with the toothed ring.

[0011] As a further preferred embodiment of this technical solution, each of the three sets of insert rods is provided with a second oil groove, and each of the three sets of insert rods is fitted with a sliding sleeve, the sliding sleeve being slidably connected to the insert rod through the second oil groove.

[0012] This utility model provides a double-edged high-speed forming reamer, which has the following beneficial effects:

[0013] (1) This utility model achieves synchronous adjustment of the distance between the four sets of locking rods by adjusting the sliding rod installed inside the blade body in conjunction with the first and second rods distributed crosswise between the four sets of locking rods. In turn, it cooperates with the four sets of corresponding locking grooves in the cutting head to achieve quick installation or disassembly between the blade body and the cutting head. This allows the cutting head in the reamer to be flexibly replaced according to the wear condition, avoiding the problem of low blade reusability caused by the integrated blade head and blade body of traditional molded reamers. In addition, the sliding of the piston in the four sets of locking rods can cooperate with the hydraulic oil in the first oil groove to expand the locking rod and strengthen the connection between the blade body and the cutting head.

[0014] (2) This utility model enables the quick installation or removal of the tool body on the mounting base by means of three sets of adjustable spacing clamping rods in the mounting base and expandable insert rods on the clamping rods, so that different reamers can be quickly disassembled, replaced and installed during the processing of the reamer, thus avoiding the impact on the working efficiency of the reamer.

[0021] 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.

[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, a double-edged high-speed forming reamer includes a mounting base 3, a blade body 1, and a cutting head 2. The cutting head 2 has four symmetrically distributed slots 4. An adjusting rod 5 is slidably installed inside the blade body 1. Four symmetrically distributed locking rods 6 are arranged around the blade body 1 and the adjusting rod 5, with each locking rod 6 corresponding to a slot 4. The cutting head 2 is movably engaged with the four locking rods 6 through the slots 4. Each of the four locking rods 6 has a first oil groove 9. A piston 10 is sleeved on each of the four locking rods 6, and each piston 10 is slidably connected to its corresponding locking rod 6 through the first oil groove 9. The blade body 1 has three sets of rings. The mounting base 3 has three sets of annularly distributed adjustment blocks 12 within the slots 24 arranged in a circular pattern. Each of the three sets of adjustment blocks 12 is fixedly mounted with a clamping rod 20, which is movably engaged with the blade body 1. Each of the three sets of clamping rods 20 is fixedly mounted with an insertion rod 21, which is movably engaged with the blade body 1 via the three sets of slots 24. A first support rod 7 and a second support rod 8 are provided between the four sets of clamping rods 6, the adjustment rod 5, and the blade body 1. The first support rod 7 and the second support rod 8 are arranged in a crisscross pattern. The two ends of the first support rod 7 are rotatably connected to the adjustment rod 5 and the clamping rod 6 respectively via a pivot. The left end of the second support rod 8... The second support rod 8 is slidably connected to the locking rod 6, and its right end is rotatably connected to the blade body 1 via a pivot. A push plate 11 is slidably installed inside the blade body 1. All four sets of pistons 10 are slidably connected to the push plate 11. When installing or removing the blade head 2, the sliding of the adjusting rod 5 in the blade body 1, in conjunction with the locking rod 6, the adjusting rod 5, and the first and second support rods 7 and 8 intersecting between the blade body 1, causes the first and second support rods 7 and 8 to simultaneously rise or retract, thereby adjusting the distance between the four sets of locking rods 6. When the four sets of locking rods 6 engage with the locking groove 4, the installation of the blade head 2 is completed, and the four sets of locking rods 6 move away from the locking groove 4. When the blade head 2 is released from its fixed position, the sliding of the push plate 11 within the blade body 1 causes the four sets of pistons 10 to slide synchronously, compressing the hydraulic oil in the first oil groove 9 of the clamping rod 6. This causes the wall of the clamping rod 6 to expand, strengthening the clamping rod 6's fixation strength to the clamping groove 4 and the blade head 2. During the adjustment of the distance between the four sets of clamping rods 6, the piston 10 slides with the corresponding clamping rod 6. The direction of movement of the clamping rod 6 does not interfere with the sliding connection direction between the four sets of pistons 10 and the push plate 11, and does not affect the adjustment of the distance between the four sets of clamping rods 6.

[0023] like Figure 4 and Figure 5As shown, each of the three sets of adjusting blocks 12 is equipped with a slider 13. The mounting base 3 has three sets of sliding grooves 14 corresponding to the adjusting blocks 12. The adjusting blocks 12 are slidably connected to the mounting base 3 via the sliders 13 and sliding grooves 14. A turntable 15 is rotatably mounted inside the mounting base 3, and the turntable 15 is rotatably connected to the mounting base 3 via a rotating frame 17. A ring tooth 16 is fixedly mounted on the turntable 15. All three sets of adjusting blocks 12 are meshed with the turntable 15 via the ring tooth 16. A toothed ring 18 is sleeved on each of the three rotating frames 17. A rack 19 is slidably mounted inside the mounting base 3, meshing with the toothed ring 18. Each of the three sets of insert rods 21 has a second oil groove 22. A sliding sleeve 23 is sleeved on each of the three sets of insert rods 21, and the sliding sleeve 23 is slidably sleeved with the insert rod 21 via the second oil groove 22. During the sliding process of the rack 19 in the mounting base 3… The gear ring 18, in conjunction with the rotating frame 17, causes the turntable 15 to rotate. As the ring gear 16 on the turntable 15 rotates, the three sets of adjusting blocks 12 are pushed synchronously under the limiting action of the slider 13 and the slide groove 14. The three sets of adjusting blocks 12 drive the clamping rods 20 to slide inward synchronously on the mounting base 3 and clamp the blade 1. Before adjusting the distance between the clamping rods 20, the insertion rods 21 on the clamping rods 20 are aligned with the slots 24 on the blade 1. Therefore, after the clamping rods 20 are in contact with the blade 1, the insertion rods 21 are inserted into the corresponding slots 24. The sliding sleeves 23 on the insertion rods 21 slide, squeezing the hydraulic oil in the second slide groove 14, causing the insertion rods 21 to close and expand, squeezing the inner wall of the slot 24. The three sets of clamping rods 20 strengthen the fixing strength of the mounting base 3 for the blade 1, making the installation of the reamer quick and convenient.

[0024] This utility model provides a double-edged high-speed forming reamer. Its working principle is as follows: When installing or removing the cutter head 2, the sliding of the adjusting rod 5 in the cutter body 1, in conjunction with the locking rod 6 and the adjusting rod 5, as well as the first and second support rods 7 and 8 distributed intersectingly between the cutter body 1, causes the first and second support rods 7 and 8 to simultaneously rise or retract, thereby adjusting the distance between the four sets of locking rods 6. When the four sets of locking rods 6 engage with the locking groove 4, the cutter head 2 is installed. When the four sets of locking rods 6 move away from the locking groove 4, they disengage from fixing the cutter head 2. After fixing the cutter head 2 on the cutter body 1, the sliding of the push plate 11 within the cutter body 1 drives the four sets of pistons 10 to slide synchronously, compressing the hydraulic oil in the first oil groove 9 of the locking rod 6, thereby expanding the wall of the locking rod 6 and strengthening the fixing strength of the locking rod 6 to the locking groove 4 and the cutter head 2. During the adjustment of the distance between the four sets of locking rods 6, the piston 10 slides with the corresponding locking rod 6, and the direction of movement of the locking rod 6 is related to the four sets of pistons. The sliding connection direction between 10 and push plate 11 does not interfere with each other and does not affect the adjustment of the distance between the four sets of clamping rods 6. During the sliding process of rack 19 in mounting base 3, it cooperates with gear ring 18 to make the rotating frame 17 drive the turntable 15 to rotate. At the same time, the ring tooth 16 on the turntable 15 rotates accordingly. Under the limiting action of slider 13 and slide groove 14, it pushes the three sets of adjusting blocks 12 synchronously. The three sets of adjusting blocks 12 drive the clamping rod 20 to slide inward synchronously on mounting base 3 and clamp the blade 1. Before adjusting the distance between clamping rods 20, the insertion rod 21 on clamping rod 20 is first aligned with the slot 24 on blade 1. Therefore, after clamping rod 20 is in contact with blade 1, insertion rod 21 is inserted into the corresponding slot 24. Sliding sleeve 23 on insertion rod 21 slides, squeezing the hydraulic oil in the second slide groove 14 to make insertion rod 21 close and expand to squeeze the inner wall of slot 24. With the help of the three sets of clamping rods 20, the fixing strength of mounting base 3 to blade 1 is strengthened, and the installation of reamer is quick and convenient.
