Description

Technical Field

[0001] The invention relates to the technical field of drilling devices, and in particular to a flywheel drilling mechanism. Background Art

[0002] During the production process of flywheels, holes need to be drilled on the disc surface. For flywheel holes with regular arrangement, the drilling technology is very mature and the drilling efficiency is very high. However, for flywheel holes with irregular arrangement, multiple positioning is required, which is inefficient. For example, our company is currently producing a batch of flywheels with irregular arrangement of holes on the flywheel surface and roughly distributed on a rectangular frame (see attached Figure 4 ). This rectangular frame is shown as the first hole edge 13, the second hole edge 14, the third hole edge 15 and the fourth hole edge 16 connected in sequence. Due to production requirements, the drill holes 11 are distributed on these hole edges. In some cases, the rectangular frame is not symmetrically arranged along the center wheel hole 12 of the flywheel 10, which further increases the difficulty of subsequent flywheel drilling. During the drilling process, it is necessary to continuously translate or rotate the drill or flywheel to locate the drilling position multiple times, which reduces the drilling efficiency of the flywheel.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 6 As shown, the present invention provides a flywheel drilling mechanism, including a positioning mechanism 1, a drilling machine 2, an adjustment mechanism 3 and a cleaning mechanism 4.

[0031] The positioning mechanism 1 can realize the centering clamping of the flywheel to be drilled 10. Specifically, the positioning mechanism 1 includes a workbench 101, a chuck 102 disposed on the workbench 101, and a positioning column 103 installed in the center of the chuck 102.

[0032] Wherein, the drilling machine 2 is used to drill holes in the flywheel 10;

[0033] The adjusting mechanism 3 includes a mounting plate 301 which is lifted and lowered above the positioning mechanism 1. The adjusting mechanism 3 also includes a vertical slide rail 320, on which the mounting plate 301 is slidably mounted, and a support plate 321 is disposed at the top of the vertical slide rail 320, on which a cylinder 322 connected to the mounting plate 301 at the lower end is mounted.

[0034] The first sliding rod 302 and the motor 307 are horizontally arranged on the mounting plate 301 . A rotating sleeve 308 is installed on the rotating shaft of the motor 307 . The positioning column 103 is coaxially arranged with the rotating shaft of the rotating sleeve 308 .

[0035] A third slide bar 306 is provided for horizontal sliding inside the rotating sleeve 308, a limiting slide bar 303 is slidably installed on the first slide bar 302, a second slide bar 304 which is arranged perpendicular to the first slide bar 302 is installed on the limiting slide bar 303, a sliding mounting block 305 is slidably sleeved on the second slide bar 304, the sliding mounting block 305 is hingedly installed on one end of the third slide bar 306, a return spring 309 is sleeved on the third slide bar 306 between the sliding mounting block 305 and the rotating sleeve 308, and the drilling machine 2 is installed below the sliding mounting block 305.

[0036] In order to make the adjustment mechanism 3 suitable for various rectangular distribution drill holes 11 on the flywheel 10, two guide rails 310 are arranged on the mounting plate 301 parallel to the second slide bar 304, and sliding blocks 311 are slidably arranged on the guide rails 310, respectively, and the two sliding blocks 311 can be driven by the power assembly to move synchronously. Specifically:

[0037] The power assembly includes a lead screw 316 which is mounted on the corresponding sliding block 311 through a lead screw nut (not shown in the figure). The lead screw 316 is arranged parallel to the guide rail 310. The two lead screws 316 are connected by a pulley set 317. One of the lead screws 316 is driven to rotate by a turntable 318.

[0038] First threaded sections 312 are provided at both ends of the first slide rod 302, and the ends of the first threaded sections 312 are installed on the sliding block 311 on the corresponding side. First nut limiting sleeves 313 are installed on the two first threaded sections 312, and the first nut limiting sleeves 313 are used to limit the moving distance of the limiting slide 303 on the first slide rod 302; a second threaded section 314 is provided at one end of the second slide rod 304 where the limiting slide 303 is not provided, and a second nut limiting sleeve 315 cooperating therewith is provided on the second threaded section 314, and the second nut limiting sleeve 315 is used to limit the moving distance of the sliding mounting block 305.

[0039] Furthermore, the inner ends of the first nut limiting sleeve 313 and the second nut limiting sleeve 315 are installed with a limiting sleeve 319, and the inner diameter of the limiting sleeve 319 is larger than the diameter of the first slide bar 302 and the second slide bar 304. Through the limiting effect of the limiting sleeve 319, the limiting slide 303 slidably installed on the first slide bar 302 and the sliding mounting block 305 slidably installed on the second slide bar 304 will not move on the threaded section, thereby improving the smoothness of the displacement of the two.

[0040] The cleaning mechanism 4 is used to clean the drilled holes on the surface of the flywheel 10. Specifically:

[0041] The cleaning mechanism 4 includes a vacuum cleaner 401, a vacuum tube 402 connected to the vacuum cleaner 401, the second slide bar 304 and the second threaded section 314 are both hollow tubes, a plurality of vacuum holes 403 are provided on the bottom wall of the second slide bar 304, and the other end of the vacuum tube 402 is connected to the end of the second threaded section 314. In this way, when the second slide bar 304 reciprocates along the surface of the flywheel, the drilling debris on the surface of the flywheel 10 can be cleaned.

[0042] The working principle of the device of the present invention is:

[0043] 1. Adjusting the drilling margin: Rotate the turntable 318, which drives the lead screw 316 connected thereto to rotate. Since the two lead screws 316 are connected via the pulley set 317, the two lead screws 316 can rotate synchronously. Thus, the sliding block 311 mounted on the lead screw 316 moves synchronously under the guidance of the guide rail 310, so that the first slide bar 302 installed between the two slide blocks 311 moves in a direction perpendicular to the first slide bar 302, which can adjust the distribution of the first hole edge 13 relative to the center wheel hole 12 of the flywheel 10;

[0044] Afterwards, the first nut limiting sleeves 313 on the first threaded sections 312 at both ends of the first slide bar 302 are rotated, and the limiting sleeves 319 on the first nut limiting sleeves 313 move relative to the first slide bar 302, which can adjust the distribution of the first hole edge 13 and the second hole edge 14 relative to the center wheel hole 12 of the flywheel 10;

[0045] Then, the second nut limiting sleeve 315 on the second threaded section 314 at the end of the second slide bar 304 is rotated to make the limiting sleeve 319 on the second nut limiting sleeve 315 also slide relative to the second slide bar 304, so as to adjust the distribution of the fourth hole edge 16 relative to the center wheel hole 12 of the flywheel 10;

[0046] 2. Positioning the flywheel: Align the center wheel hole 12 of the flywheel 10 with the positioning column 103 on the chuck 102 to complete the initial positioning, and then drive the chuck 102 so that the claws of the chuck 102 clamp the middle part of the flywheel from all sides to achieve the center positioning and clamping of the flywheel 10.

[0047] 3. Drilling: Start the motor 307, the motor 307 drives the rotating sleeve 308 installed below to rotate, and the third sliding rod 306 slidably sleeved inside the rotating sleeve 308 will rotate.

[0048] If the flywheel 10 is processed by drilling 11 in sequence according to the directions of the first hole edge 13 , the second hole edge 14 , the fourth hole edge 16 and the third hole edge 15 .

[0049] During the rotation of the third slide bar 306, the limiting slide cylinder 303 at one end of the second slide bar 304 is limited by the limiting sleeves 319 at both ends of the first slide bar 302. During the sliding process from one end to the other end, since the return spring 309 between the sliding mounting block 305 and the rotating sleeve 308 is always in a compressed state, the sliding mounting block 305 will press against the end of the second slide bar 304 close to the limiting slide cylinder 303 and make horizontal movement, so that the drilling machine 2 installed on the sliding mounting block 305 performs a drilling operation along the first hole edge 13 parallel to the first slide bar 302;

[0050] Afterwards, when the third slide bar 306 rotates further, since the limiting slide cylinder 303 at the end of the second slide bar 304 is limited by the limiting sleeve 319 at one end of the first slide bar 302, the second slide bar 304 will not move along the first slide bar 302. At this time, the drilling machine 2 on the sliding mounting block 305 can only move horizontally along the second slide bar 304 in the direction of the second hole edge 14 and complete the drilling operation of the second hole edge 14.

[0051] When the sliding mounting block 305 moves along the second slide bar 304 to the position where the limiting sleeve 319 at the end of the second slide bar 304 is limited, with the rotation of the third slide bar 306, the limiting slide cylinder 303 at the upper end of the second slide bar 304 will move horizontally in the opposite direction along the first slide bar 302. With the horizontal movement of the second slide bar 304, the sliding mounting block 305 abutting against the limiting sleeve 319 at the end of the second slide bar 304 will move horizontally along the fourth hole edge 16, and the drilling machine 2 at its lower end will complete the drilling operation along the fourth hole edge 16.

[0052] Finally, when the limiting slide cylinder 303 at the upper end of the second slide bar 304 is limited by the limiting sleeve 319 at the other end of the first slide bar 302, the second slide bar 304 does not move, and as the third slide bar 306 rotates, the sliding mounting block 305 moves horizontally along the second slide bar 304 along the third hole edge 15, and the drilling machine 2 at the lower end thereof completes the drilling operation along the third hole edge 15. After the above operation is completed, all the drill holes 11 on the flywheel 10 are processed along the rectangular frame.

[0053] In the above process, when the second slide bar 304 reciprocates, the dust suction hole 403 at the lower end of the second slide bar 304 will, under the action of the vacuum cleaner 401 , clean the debris formed during the drilling process from the surface of the flywheel 10 .

[0054] The present invention cooperates among a positioning mechanism, a drilling machine, an adjusting mechanism and a cleaning mechanism, and firstly adjusts the end node positions of the first slide bar 302 and the second slide bar 304 of the adjusting mechanism to limit the distribution of the rectangular frame of the flywheel drilling part; then the third slide bar 306 mounted on the rotating sleeve 308 is driven by a motor to rotate, and the drilling machine 2 on the sliding mounting block 305 at the end of the third slide bar 306 gradually rotates the flywheel along the rectangular frame. On the one hand, there is no need to repeatedly locate the drilling position during the batch drilling of flywheels, and the device can be applied to the processing of flywheels with holes distributed in rectangular frames of different specifications, thereby improving the drilling efficiency of the flywheel; on the other hand, during the drilling process, it can also reciprocate on the flywheel disc surface to absorb drilling debris, thereby ensuring the cleanliness of the flywheel drilling process.

[0055] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
