Description

An adjustable boring mechanism for gearbox housing machining

Technical Field

The invention belongs to the field of gearboxes and relates to a boring technology, in particular to an adjustable boring mechanism for machining a gearbox housing.

Background technique

The transmission is a mechanism used to change the speed and torque from the engine. It can fix or change the transmission ratio of the output shaft and the input shaft in stages. It is also called a gearbox. The transmission consists of a speed transmission mechanism and an operating mechanism. Some cars also have a power output mechanism. Most transmission mechanisms use ordinary gear drives, and some use planetary gear drives.

The gearbox is a very important component in the vehicle. It can change the transmission ratio and increase the torque and speed of the driving wheel. During the production and processing of the gearbox housing, in order to expand the aperture of the forged, cast or drilled holes on the housing, improve the accuracy or reduce the surface roughness, thereby reducing the friction between the gearbox and the internal gears when the gearbox is used later, it is necessary to use a boring structure to bore the transmission housing.

When the existing boring structure processes the gearbox housing, in order to avoid the high temperature generated by the contact between the boring cutter and the gearbox housing and the influence on the tool and the workpiece, the cutting fluid is used for lubrication and cooling. However, the existing boring mechanism cannot process the cutting fluid for reuse during use, which increases the processing cost of the gearbox housing and is not conducive to the recycling and reuse of the metal waste mixed in the cutting fluid.

Therefore, we propose an adjustable boring mechanism for gearbox housing machining to solve the above problems.

It should be noted that the carrying frame 18 is adapted to the space size at the top of the storage box 1, the sponge pad 20 located inside the carrying frame 18 can perform preliminary filtration on the dripping cutting fluid, and the perforated plate 22 can place the gearbox housing above without affecting the reception of waste and cutting fluid.

When the present invention is specifically implemented:

In the present invention, when boring the gearbox housing using the boring mechanism, the staff will first select an appropriate amount of threaded rods 3 149, fixing plates 1410, etc. according to the shape of the gearbox housing to be bored, and rotatably install them on the appropriate threaded holes 2 145 on the connecting ring 143, and then rotate the threaded rods 4 1411 according to the shape of the gearbox housing. After the clamping plate 1412 on one side contacts the outside of the gearbox housing, adjust the positions of the other threaded rods 4 1411, and at the same time avoid the clamping plate 1412 from being clamped on the outside of the gearbox housing as much as possible to affect the position of the subsequent boring of the outside of the gearbox housing.

After the gearbox housing is stably clamped by the clamping assembly 14, the electric telescopic rod 45 can be extended downward, and the driver 7 can drive the boring tool 10 to rotate rapidly. During the downward movement of the boring tool 10, the transparent protective cover 122 first contacts the gearbox housing, and then the boring tool 10 continues to move forward. During this process, the boring tool 10 contacts the hole in the gearbox housing, and the inner wall of the hole can be cut smoothly. In the process of boring, the water pump inside the storage box 1 also keeps pumping the water inside through the delivery pipe 123, and relies on The dripper 124 drips on the tool head of the boring tool 10 to prevent the boring tool 10 and the gearbox housing from generating heat due to friction when in contact with each other, which may cause deformation or damage to the boring tool 10 or the boring hole of the gearbox housing, thereby affecting the service life of the boring tool 10 and the processing quality of the gearbox housing. At the same time, the cut metal waste splashes into the transparent protective cover 122, which can prevent a large amount of metal waste from splashing out, making it inconvenient to collect and recycle it later, and may also cause harm to the staff standing around the boring mechanism;

After boring a hole in the gearbox housing, the electric telescopic rod 45 can be retracted. During the retraction process, the compression spring 121 is not compressed and returns to its original position, and the metal waste inside the transparent protective cover 122 can fall out and fall on the perforated plate 22. At the same time, the cutting fluid and some fine metal waste can pass through the perforated plate 22 and the sponge pad 20 and return to one side of the storage box 1. After that, they are filtered again by the filter element 17 and drip out again through the delivery pipe 123.

When boring holes on the side of the gearbox housing or other positions, the motor 2 43 can control the threaded rod 2 42 to rotate, so that the electric telescopic rod 45 moves forward or backward along the threaded rod 2 42. At the same time, the motor 3 146 can also be started to drive the gear ring 144, the connecting ring 143 and the gearbox housing between the multiple clamping plates 1412 to rotate through the gear 148, so as to bore holes in other positions on the gearbox housing. At the same time, when boring holes on the side of the gearbox housing, the motor 1 6 can be rotated to drive the entire support assembly 4 to rotate to a certain angle to the side, and the motor 3 146 can cooperate to drive the gearbox housing clamped in the middle of the clamping assembly 14 to rotate. When the position where the hole needs to be bored is rotated to the position corresponding to the boring tool 10, the electric telescopic rod 45 can be extended to bore the gearbox housing.

In the process of boring the gearbox housing, if the size of the bored hole needs to be changed, the boring mechanism is paused, and the staff can rotate and adjust the inclination angle of the boring tool 10 to facilitate cutting holes of other sizes. The staff can also lift the transparent protective cover 122 upward, and then rotate the threaded hole 11 at one end of the boring tool 10 out of the threaded rod 9, and then reinstall the boring tool 10 of other sizes at the bottom of the mounting column 8, so as to facilitate the boring process of the gearbox housing.

After boring a gearbox housing, when one or two threaded rods 1411 are rotated to loosen the clamping plate 1412 and the gearbox housing, the gearbox housing can be taken out from between the clamping plates 1412, and then the staff can clean up the large volume of metal waste inside the gearbox housing or the metal waste falling on the perforated plate 22, and then re-clamp the gearbox housing that needs to be bored in the middle of the clamping assembly 14;

When boring the gearbox housing is finished or when taking a break, the worker can disassemble the support assembly 4 from the work platform 2, and then remove the perforated plate 22 from the bearing frame 18, and then take out the sponge pad 20 and clean it on one side of the storage box 1, collect the metal waste filtered out of the sponge pad 20, or directly shake out the metal waste in the sponge pad 20, and then put the sponge pad 20 back into the bearing frame 18, and at the same time, the worker can collect the metal waste filtered out of the storage box 1, and take out the filter 17 from the limit frame 15 for cleaning, so as to facilitate the continued use later;

When using the boring mechanism to process other workpieces, the staff can disassemble the support assembly 4 and use bolts to rotate the support assembly 4 90° to install it on the work platform 2. At the same time, the motor 6 controls the support assembly 4 to rotate 90°, so that the support assembly 4 and the clamping assembly 14 are more suitable for boring other workpieces from a direction parallel to the ground.

By installing a motor 1 6 on one side of the support seat 3, the motor 1 6 can drive the support assembly 4 to rotate, and the electric telescopic rod 45 in the support assembly 4 can be moved under the drive of the motor 2 43 and the threaded rod 2 42, and various adjustments can be made to bore holes at different locations of the gearbox housing. The motor 3 146, the gear 148 and the gear ring 144 in the clamping assembly 14 can also drive the gearbox housing below that needs to be bored to rotate and adjust, and can automatically bore holes at different locations of the gearbox housing, without the need for the staff to adjust the position of the gearbox housing all the time, which is more labor-saving and the processing speed is also improved.

By arranging a protective component 12 at the bottom of the driver 7, when the boring tool 10 is boring the gearbox housing, the cut metal waste can be blocked by the transparent protective cover 122 to prevent the metal waste from directly splashing out. At the same time, the delivery pipe 123 and the dripper 124 are used in conjunction with the storage box 1 to cool the high-speed rotating boring tool 10 and the gearbox housing boring hole during the boring tool 10 boring process, thereby preventing the boring tool 10 or the gearbox housing from being deformed due to high temperature generated by friction between the boring tool 10 and the gearbox housing, affecting the boring quality, and also affecting the service life of the boring tool 10;

By installing a clamping assembly 14 on the top of the working platform 2, the gearbox housing in the middle can be stably clamped during the boring process of the gearbox housing, ensuring that the position of the gearbox housing is stable and does not move when the fast-rotating boring tool 10 contacts the gearbox housing, thereby ensuring the boring quality of the gearbox housing;

By setting a storage box 1 at the bottom of the working platform 2, the filter 17 is stuck inside the storage box 1, and the sponge pad 20 inside the supporting frame 18 can initially filter the cutting fluid dripping downward and the metal waste mixed therein, while the filter 17 can filter the used cutting fluid again, and then the cutting fluid is processed by the centrifuge 26, so that the cutting fluid can be processed and cooled and then recycled. At the same time, the two storage chambers 25 can be used alternately. When the cutting fluid is replaced, it will not affect the normal processing of the gearbox housing.
