Description

Technical Field

[0001] The utility model relates to the technical field of main roller shaft processing, in particular to a large deep hole boring machine for main roller shaft production. Background Art

[0002] A large deep hole boring machine is a machine tool used to process deep holes in large workpieces such as roller shafts. It usually has deep hole drilling and boring technology, and can achieve high-precision and high-efficiency deep hole processing. When using a boring machine for main roller shaft production, the depth of the boring hole needs to be different. When the boring hole depth is too long, a longer boring tool is required, which is prone to instability during drilling.

[0003] According to the Chinese patent publication number CN214322713U, "A CNC large deep hole drilling and boring machine", it mainly describes that chip brushes are arranged above and below the roller. When the first drive device drives the clamping device to move, the roller moves on the slide rail and drives the chip brushes to rotate at the same time, which plays the role of automatically cleaning the slide rail and keeping the deep hole processing stable at a low speed. When boring is required, the length of some boring tools is not suitable for the depth of the boring hole, which is prone to instability during drilling.

[0004] Therefore, a large deep hole boring machine for main roller production is proposed to solve the problem that when boring is required, the length of some boring tools is not suitable for the depth of the boring hole, which easily causes instability during drilling. Utility Model Content

The second screw is threadedly connected to the slide. The slide is driven to move by the rotation of the second screw, and the positions of the movable platform, the upper clamping block and the lower clamping block can be adjusted.

[0010] As an optimal technical solution of the present invention, grooves are provided on the upper clamping block and the lower clamping block, and a contact roller is connected to the groove through a rotating shaft. The contact roller is in contact with the boring tool. By setting the contact roller, the stability of the movement of the upper clamping block and the lower clamping block can be improved during the boring process.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figure 1-3 The large deep hole boring machine for main roller production shown in the figure comprises a fixed plate 1, a material receiving table 2, a first screw 3, a slide 4, a clamping table 5 and a boring tool 6. A lateral moving mechanism and a water pump for supplying cutting fluid are provided on the slide 4. At the same time, a three-jaw chuck is provided on one side of the clamping table 5 to limit the boring tool 6. One side of the fixed plate 1 is in contact with a moving table 7. A slide groove 8 is provided at the center of the upper end of the moving table 7. A moving bar 9 is in contact with the slide groove 8. The moving bar 9 can move left and right in the slide groove 8 and is limited by a pressure rod 21 to adapt to the left and right movement of the clamping table 5. The upper end of the moving table 7 is threadedly connected with a pressure rod 21. The pressure rod 21 is pressed. The end of the rod 21 contacts the moving bar 9, and the upper end of the moving bar 9 is fixedly connected to the connecting rod 10, and the upper end of the connecting rod 10 is sleeved with a connecting sleeve 14, and the upper end of the connecting sleeve 14 is fixedly connected to the lower clamping block 11. The upper clamping block 13 cooperates with the lower clamping block 11 to achieve the effect of limiting the boring tool 6 and provide support for the boring tool 6. The upper end of the lower clamping block 11 is plugged with an auxiliary rod 12, and the auxiliary rod 12 is evenly provided with through holes and the positioning rod 20 is inserted into the through hole. The positioning rod 20 is threadedly connected to the lower clamping block 11, and the upper end of the auxiliary rod 12 is fixedly connected to the upper clamping block 13. The upper clamping block 13 and the lower clamping block 11 are both provided with limiting grooves 15.

[0018] Among them, a baffle 16 is set on the bottom side of the boring tool 6, and the baffle 16 is fixedly connected to the bottom end of the connecting rod 10. By setting the baffle 16 on the bottom side of the boring tool 6, when the cutting fluid flushes out the boring hole waste, it can prevent the boring tool 6 waste from contacting the first screw 3 and the second screw 18, thereby improving the stability during operation.

[0019] The movable platform 7 is in contact with the support rods 17 , and the support rods 17 are fixedly connected to four sides of the bottom end of the shield 16 . By providing the support rods 17 , the stability of the shield 16 is improved.

[0020] Among them, a second screw 18 is threadedly connected to the slide 4, and the second screw 18 is fixedly connected to the output end of the drive motor. The drive motor is fixedly connected to one side of the movable platform 7. By setting the drive motor to drive the second screw 18 to rotate, the movable platform 7 can be moved on the fixed plate 1, so that when boring, the upper clamping block 13 and the lower clamping block 11 can provide adaptive movement when they are close to one end of the main roller shaft.

[0021] Among them, the boring tool 6 is in contact with the contact roller 19, and the contact roller 19 is connected to the groove by rotating the rotating shaft. The groove is located on the upper clamping block 13 and the lower clamping block 11. By setting the contact roller 19, the upper clamping block 13 and the lower clamping block 11 can reduce friction when they move relative to the boring tool 6, thereby improving the rotation stability of the boring tool 6.

[0022] Working principle: Select a suitable boring tool 6 and clamp it with a three-jaw chuck, then place the main roller on the receiving table 2. After adjusting the center point, limit the upper clamping block 13 and the lower clamping block 11 on the boring tool 6, and limit it through the positioning rod 20, then adjust the drive motor to drive the second screw 18 to rotate, and make the connecting rod 10 located in the center position of the boring tool 6, use the clamping table 5 to drive the boring tool 6 to rotate, and bore the inside of the main roller, and at the same time, the moving bar 9 carries the connecting rod 10 for adaptive adjustment. At this time, the water pump supplies cutting fluid, and overflows through the hole at one end of the boring tool 6 to reduce the temperature during boring. At the same time, the cutting fluid carries waste chips to the upper side of the baffle 16, and adjusts the drive motor according to the feed depth and controls the distance between the slide 4 and the moving table 7 to prevent the upper clamping block 13 and the lower clamping block 11 from obstructing the boring of the main roller.
