Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing tooling technology, specifically referring to a flywheel housing drilling tooling. Background Technology

[0002] As a key component of the engine transmission system, the drilling accuracy of the flywheel housing directly affects subsequent assembly and performance. Existing tooling has the following problems during flywheel housing drilling:

[0003] 1. The clamping structure of traditional drilling fixtures has a fixed angle, which cannot be adjusted according to the shape of flywheel housings of different specifications. Special fixtures are required to adapt to them, which is cumbersome and increases production costs. At the same time, the fixture is prone to loosening after it is fixed, which causes the flywheel housing to shift during the drilling process and affects the hole position accuracy.

[0004] 2. Difficulty in cleaning drilling residue: Metal residue generated during drilling tends to accumulate on the surface of the tooling or in the gaps of the flywheel housing, which not only affects subsequent drilling operations but also requires frequent manual cleaning, increasing labor intensity; some residue may fall into the gaps inside the tooling and is difficult to remove, and long-term accumulation can easily cause tooling failure.

[0005] Therefore, this utility model proposes a flywheel housing drilling tool to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is the poor positioning adaptability and difficulty in cleaning residue of existing flywheel housing drilling fixtures.

[0007] To achieve the above functions, the technical solution adopted by this utility model is as follows: A flywheel housing drilling fixture includes a base and a support column fixedly mounted on the base. A connecting platform is fixedly connected to the upper end of the support column, and a drilling machine is fixedly connected to the lower end of the connecting platform. A drill bit is provided at the lower end of the drilling machine. A reserved groove is fixedly opened on the base below the drilling machine. Cleaning components for cleaning drilling residue are provided on both sides of the reserved groove. A sliding groove body is slidably mounted on the inner wall of the reserved groove, and a drive motor for driving the sliding groove body to move is fixedly mounted on one side wall of the base. A positioning component for fixing the flywheel housing is slidably mounted on the sliding groove body. The drive motor can drive the sliding groove body to move along the reserved groove, thereby adjusting the relative position of the flywheel housing and the drill bit on the positioning component to adapt to different drilling requirements.

[0008] Furthermore, the cleaning component includes two L-shaped shells fixedly connected to the upper end of the base and located on both sides of the reserved slot. The front section of the L-shaped shell is fixedly provided with an inclined air outlet, and multiple fans located on one side of the inclined air outlet are uniformly fixed inside the L-shaped shell. The airflow generated by the fans is guided by the inclined air outlet and can be accurately blown towards the drilling area, blowing the residue into the reserved slot for collection, thus avoiding residue accumulation.

[0009] Furthermore, multiple triangular rods are fixedly arrayed between the two side walls of the reserved groove, and gaps are reserved between each triangular rod; the triangular rods can prevent tools or small materials from accidentally falling into the depth of the reserved groove, while not affecting the collection of residues, and making it easy to remove accidentally dropped materials during subsequent cleaning.

[0010] Furthermore, the positioning component includes a disc slidably disposed within a sliding groove. A slider located within the sliding groove is fixedly connected to the lower end of the disc. A servo motor is fixedly disposed at one end of the sliding groove, and a lead screw is connected to the output end of the servo motor. The other end of the lead screw passes through the slider and is rotatably connected to the other end of the sliding groove. A cylinder is fixedly disposed relative to the upper end of the disc. A T-block is connected to the output end of the cylinder, and a clamping element is disposed at one end of the T-block. The servo motor drives the lead screw to rotate, which can drive the slider and the disc to move along the sliding groove. In conjunction with the cylinder, the T-block is pushed up and down, realizing multi-dimensional adjustment of the flywheel housing position.

[0011] Furthermore, the clamping component includes a clamp one and a clamp two rotatably connected to one end of the T-block, and two rotating shafts are fixedly arranged at the connecting end of the clamp two. The center of the connecting end of the clamp one is fixedly connected to another rotating shaft adapted to the two rotating shafts. A limiting block is provided at the connecting end of the clamp one and the clamp two for fixing them together. Through the rotation of the rotating shafts, the opening angle of the clamp one and the clamp two can be adjusted to adapt to different specifications of flywheel housings. The limiting block can fix the adjusted angle to prevent loosening.

[0012] Furthermore, the rotating shaft is provided with a limiting groove consisting of a plurality of rectangular ring arrays, and the size of the limiting block is the same as that of the rectangle; the limiting block is inserted into the limiting groove at different positions, which can realize multiple fixed positions of the clamp opening and closing angle, and improve the adaptability.

[0013] Furthermore, the limiting groove is made of metal, and a magnetic block that attracts the rotating shaft is fixedly connected to the upper end of the limiting block; the attraction between the magnetic block and the metal rotating shaft can enhance the fixing effect of the limiting block, prevent the limiting block from falling off due to drilling vibration, and ensure the clamping stability of the clamp on the flywheel housing.

[0014] The beneficial effects of this utility model by adopting the above structure are as follows:

[0015] 1. By pulling out the limiting block, the angle restriction of clamp one and clamp two can be released. After adjusting the opening and closing angle by rotating the shaft, insert the limiting block and use the magnetic block and the metal rotating shaft to fix it, so as to achieve precise clamping of flywheel housings of various specifications. There is no need to replace the special clamps, which reduces costs and makes the operation convenient.

[0016] 2. The airflow generated by the fan is guided through the slanted air outlet to the drilling area, blowing the residue into the reserved groove to avoid accumulation; the triangular rod can prevent tools from accidentally falling into the depth of the reserved groove, while not affecting the collection of residue, making subsequent cleaning more convenient.

[0026] Example 1:

[0027] like Figure 1-6 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: A flywheel housing drilling fixture includes a base 1 and a support column 2 fixedly installed on the base 1. A connecting platform 4 is fixedly connected to the upper end of the support column 2, and a drilling machine 5 is fixedly connected to the lower end of the connecting platform 4. A drill bit 6 is provided at the lower end of the drilling machine 5. A reserved groove 7 located below the drilling machine 5 is fixedly opened on the base 1. Multiple triangular rods 8 are fixedly arrayed between the two side walls of the reserved groove 7. Cleaning components are provided on both sides of the reserved groove 7. A sliding groove body 9 is slidably installed on the inner wall of the reserved groove 7. A drive motor is fixedly installed on one side wall of the base 1. A positioning component is slidably installed on the sliding groove body 9.

[0028] like Figure 1-6 As shown, the cleaning assembly includes two L-shaped shells 3 fixedly connected to the upper end of the base 1 and located on both sides of the reserved slot 7. An oblique air vent 22 is fixedly provided at the front end of each L-shaped shell 3, and multiple fans 23 are evenly fixed inside the L-shaped shell 3. The positioning assembly includes a disc 10 slidably disposed within a sliding groove 9. A slider 13 is fixedly connected to the lower end of the disc 10. A servo motor 11 is fixedly disposed at one end of the sliding groove 9. A lead screw 12 passing through the slider 13 is connected to the output end of the servo motor 11. The disc 10... A cylinder 14 is fixedly installed at the upper end. A T-block 15 is connected to the output end of the cylinder 14. A clamping component is provided at one end of the T-block 15. The clamping component includes a clamp 16 and a clamp 27 that are rotatably connected to each other. The clamp 27 is provided with two rotating shafts 18 at the connecting end. The clamp 16 is provided with one rotating shaft 18 at the connecting end. A rectangular limiting groove 19 is provided on the rotating shaft 18. A limiting block 20 is provided at the connecting end of the clamp 16 and the clamp 27 to fix the two together. A magnetic block 21 is fixedly connected to the upper end of the limiting block 20.

[0029] Place the flywheel housing to be processed on the disc 10, and adjust the clamping parts according to the shape of the flywheel housing: pull out the limiting block 20 to release the angle restriction on clamp 16 and clamp 2 17, and adjust the opening and closing angle of the two by rotating the shaft 18 until the clamps fit against the outer wall of the flywheel housing; insert the limiting block 20 into the limiting groove 19 at the corresponding position, and the magnetic block 21 and the metal shaft 18 are attracted and fixed, thus completing the adjustment of the clamping parts to adapt to flywheel housings of different sizes.

[0030] Example 2:

[0031] Based on Example 1, such as Figure 1-6 As shown, the drive motor is started, which drives the sliding groove 9 to move along the reserved groove 7. At the same time, the servo motor 11 is started, and the lead screw 12 drives the slider 13 and the disc 10 to slide along the sliding groove 9. The cylinder 14 pushes the T-block 15 and the first fixture 16 and the second fixture 17 to move, and fixes the flywheel housing to be drilled.
