Description

Technical Field

[0001] The utility model relates to the technical field of boring machine processing, in particular to a novel boring tool blade adjusting cooling device. Background Art

[0002] Hydraulic jacks are used more and more frequently in construction machinery and hydraulic supports. When the service life of the jack reaches a certain limit, problems such as unloading, fluid leakage, cylinder swelling, and seal aging that need to be replaced will gradually occur. Recently, the replacement and maintenance volume of jacks has gradually increased. Among them, the production and maintenance volume of jack cylinders is the largest, and it is also a key factor in controlling maintenance costs. Usually, maintenance is based on the principle of maximizing benefits, and those that can be recycled, repaired and reused are repaired as much as possible. However, the rust and pitting of the inner hole of the jack cylinder are deep. At present, the jack cylinder body is mostly blind bored without cutting the bottom of the cylinder, and then the inner hole is melted copper or stainless steel clad. After completion, the blind hole is bored and honed to the drawing size.

[0003] Usually, when boring blind holes in jack cylinders, it is difficult to adjust the boring tool and clean and remove the iron chips adhered to the blade. The iron chips adhered to the blade can easily cause scratches on the bored part of the inner hole and produce processing marks, which in turn causes many problems such as repeated stopping, withdrawing the boring bar, measuring and adjusting, and cleaning the iron chips adhered to the blade. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a new type of boring tool blade adjustment cooling device.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A novel boring tool blade adjustment cooling device comprises a tube body, a first disc, a second disc, a tool mounting seat, a tool body, a blade arranged on the tool body and an adjustment component;

[0007] The first disc is arranged at one end of the tube body and is provided with a first water spray hole for spraying the workpiece, and the first disc is also provided with a second water spray hole;

[0008] The second disc is arranged at the other end of the tube body and has a water pipe connection hole opened thereon to allow external water source to enter the tube body;

[0009] The tool mounting seat is mounted on the first disc and is provided with an adjustment assembly and a tool body, and the adjustment assembly is connected to the tool body to extend or retract the tool body;

[0010] A circulation component is also arranged on the tool mounting seat, and the circulation component is connected with the second water spray hole so that part of the water source can spray the blade.

[0011] The device can significantly reduce the number of times the tool is adjusted during the boring pin processing, while improving the accuracy of the tool adjustment, improving the processing efficiency and reducing the error in the size of the inner hole after processing. At the same time, during the boring pin processing, the debris attached to the blade can be sprayed in real time to remove it in time and effectively cool the blade, thereby effectively reducing the probability of subsequent debris scratching the inner hole. There is no need to repeatedly stop the machine, withdraw the boring bar, measure and adjust, and clean up the iron chips attached to the blade during boring, and the boring pin processing effect is better.

[0012] Further, the adjustment assembly includes a movable bolt and a fastening bolt;

[0013] The movable bolt thread is arranged on the tool mounting seat and the end face of the movable bolt is rotatably connected with the tool body, and the tool body is slidably arranged on the tool body mounting seat;

[0015] Furthermore, the tool mounting seat is provided with a tool body placement groove and a receiving groove, the tool body is slidably arranged in the tool body placement groove, and a movable bolt is arranged in the receiving groove.

[0016] The above scheme realizes the extension or retraction of the cutter body along the cutter mounting seat by adjusting the assembly, and simultaneously realizes the position limitation of the cutter body before and after the tool adjustment.

[0017] Furthermore, the circulation component includes a notch, a blade water spray hole, a through hole, a plug and a water inlet groove, the second water spray hole is connected to the water inlet groove, the water inlet groove is connected to the through hole, a plug is provided at one end of the through hole and the through hole is connected to the blade water spray hole, and the blade water spray hole is in the area where the notch is located and is provided on one side of the blade.

[0018] The above scheme realizes flushing and cleaning of debris on the blade and cooling of the blade by a partial water source through the circulation component in cooperation with the second water spray hole.

[0019] Furthermore, a plurality of mounting blocks are arranged on the circumference of the tube body, and rubber blocks are movably mounted on the mounting blocks.

[0020] The above scheme can effectively reduce the vibration of the boring head during the boring pin processing by using the rubber block, thereby achieving a shock-absorbing effect. At the same time, the rubber block is convenient for replacement and maintenance.

[0021] Furthermore, the surface of the rubber block is an arc surface.

[0022] The above solution sets the surface of the rubber block as an arc surface, which can further improve the fit between the rubber block and the boring machine, that is, further increase the contact area and thus achieve a better chatter reduction effect.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

There is no need to repeatedly stop the machine, withdraw the boring bar, measure and adjust, and clean the iron chips attached to the blade during boring, and the boring pin processing effect is better.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0037] like Figures 1 to 9 As shown, a novel boring tool blade adjustment cooling device comprises a tube body 1, a first disc 4 and a second disc 5 are respectively arranged on both sides of the tube body 1, a first water spray hole 41, a second water spray hole 42 and a tool mounting seat 6 are arranged on the first disc 4, a water pipe connecting hole 51 connected to a water inlet pipe is opened on the second disc 5, and the water inlet pipe is not shown in the figure. A notch 10, a blade water spray hole 11, a through hole 12, a water inlet groove 14 and an adjusting component are arranged on the tool mounting seat 6, and the adjusting component is connected to the tool body 8. A blade 9 is arranged on the tool body 8, the second water spray hole 42 is connected to the water inlet groove 14, the water inlet groove 14 is connected to the through hole 12, a plug 13 is arranged at one end of the through hole 12 and the through hole 12 is connected to the blade water spray hole 11, and the blade water spray hole 11 is located in the area where the notch 10 is located and is arranged on one side of the blade 9.

[0038] Further refinement of the embodiment of the present utility model is as follows: Figures 1 to 4 As shown, the adjustment assembly includes a movable bolt 7 and a fastening bolt 61; the movable bolt 7 is threadedly arranged on the tool mounting seat 6 and the end face of the movable bolt 7 is rotatably connected to the tool body 8, and the tool body 8 is slidably arranged on the tool body mounting seat 6; a plurality of fastening bolts 61 are threadedly arranged on the tool mounting seat 6 and their end faces are in contact with the tool body 8.

[0039] In a further optimization of the above embodiment, a tool body placement groove and a receiving groove are provided on the tool mounting seat 6, a tool body 8 is slidably arranged in the tool body placement groove, and a movable bolt 7 is arranged in the receiving groove; the tool body placement groove and the receiving groove are shown as unnumbered in the figure, and these two grooves make the tool structure design more compact.

[0040] The workflow of this utility model:

[0041] First, turn the movable bolt 7 to make the cutter body 8 move outward along the cutter body placement groove and extend. In this process, the length can be adjusted by using a vernier caliper and a pre-set vernier caliper size. After the adjustment is completed, there is generally a processing allowance between the blade 9 and the workpiece. After the extension is completed, the position of the cutter body 8 is fixed by a number of fastening bolts 61, and then the boring process of the inner hole of the workpiece can be started. The inner hole diameter of the workpiece after the boring pin processing is completed is generally about 10MM;

[0042] After the processing is completed, the cutter body 8 is immediately withdrawn from the inner hole of the workpiece, and then the inner hole size of the actual boring pin is measured. At this time, there will generally be an error between the standard size of the drawing. Then the actual processing size of the inner hole is compared with the standard size to calculate the difference, and then the head of the magnetic meter is pressed against the tip of the blade 9 of the cutter body 8, and then the movable bolt 7 is turned again. At this time, the needle reading on the magnetic meter is read. When the needle of the magnetic meter reaches the difference value, the tool adjustment can be completed, and then the inner hole can be processed again. The size of the inner hole after processing meets the design size requirements of the drawing, and then the processing error of the boring pin is further reduced and the processing size is more accurate. In this way, the tool adjustment in the boring pin process can be quickly realized, and only one adjustment is required, which greatly improves work efficiency.

[0043] During the boring pin processing, water is passed into the pipe body 1 through the water inlet pipe and the water pipe connecting hole 51, and then water is sprayed out from the first water spray hole 41 and the second water spray hole 42 at the same time. The water sprayed from the first water spray hole 41 flushes the processing debris on the workpiece and cools the workpiece, and the water sprayed from the second water spray hole 42 can be injected into the water inlet groove 14, and then the water moves along the water inlet groove 14 and is injected into the through hole 12. One end of the through hole 12 is blocked in advance by the plug 13 to prevent water from flowing out of one end of the through hole 12. Finally, water is sprayed out from the blade water spray hole 11 to flush the debris attached to the blade 9 and cool the blade 9, thereby preventing the debris attached to the blade 9 from being scratched in the subsequent inner hole during the processing;

[0044] Compared with the existing technology, the present device can significantly reduce the number of times the tool is adjusted during the boring pin processing, while improving the accuracy of the tool adjustment, improving the processing efficiency and reducing the error in the size of the inner hole after processing. At the same time, during the boring pin processing, the debris attached to the blade 9 can be sprayed in real time to remove it in time and effectively cool the blade 9, thereby effectively reducing the probability of subsequent debris scratching the inner hole. There is no need to repeatedly stop the machine, withdraw the boring bar, measure and adjust, and clean the iron chips adhered to the blade 9 during boring, and the boring pin processing effect is better.

[0045] In some embodiments, Figures 1 to 5 As shown, a plurality of mounting blocks 2 are arranged on the circumference of the tube body 1, and rubber blocks 3 are movably mounted on the mounting blocks 2; in this embodiment, the vibration of the boring head during boring pin processing can be effectively reduced by the rubber blocks 3, thereby achieving a shock-absorbing effect, and the rubber blocks 3 are convenient for replacement and maintenance.

[0046] In a further optimization of the above embodiment, the surface of the rubber block 3 is an arc surface; this can further improve the fit between the rubber block 3 and the boring machine, that is, further increase the contact area and thus achieve a better vibration reduction effect.
