TECHNICAL FIELD

[0001] The application relates to the technical field of wheel rim processing equipment, and in particular to an efficient wheel rim drilling device. BACKGROUND

[0002] A wheel rim, also known as a wheel rim, is an important part of a bicycle or motorcycle. After wheel rim shaping and insertion, the structure forms a ring shape, and then drilling is performed on the wheel rim to provide mounting points for other parts. Since the number of required drilling holes is large, the drilling process often requires a lot of time.

[0003] Chinese patent CN202222537163.6 discloses a bicycle wheel rim processing drilling device convenient to clamp. The device can clamp and fix the wheel rim through a linkage turntable and a movable clamping rod, and can adapt to wheel rims of different sizes. However, it can only drill a single position at a time, and in some wheel rims, the spaces are not all in a single direction, but sometimes at an angle to the radial direction of the wheel rim. Therefore, different angle mounting holes can be used to achieve an interlaced arrangement of reinforcing bars. CONTENT OF THE UTILITY MODEL

[0004] The application aims to provide an efficient wheel rim drilling device to solve at least one of the above technical problems.

[0005] To solve the above technical problems, the application provides an efficient wheel rim drilling device, which comprises a base, a first lifting driving member, a fixing mechanism and a plurality of drilling mechanisms. The plurality of drilling mechanisms are arranged around the fixing mechanism.

The second slider moves along the axial direction of the screw and then multiple clamps move closer or farther away from each other to achieve tightening or fixing of the wheel rim; the position of the second slider in this solution can be flexibly adjusted, so it can be suitable for fixing wheel rims of various sizes, effectively improving its compatibility; at the same time, a group of driving modules can simultaneously drive the adjustment of multiple clamping components, effectively saving the setting of the driving mechanism, reducing costs, and at the same time improving the consistency of action between multiple clamping components.

[0039] Example

[0040] The wheel rim, also known as the wheel rim, is one of the important parts of bicycles and motorcycles. After the wheel rim is shaped and pinned, it forms a ring-shaped structure. Then, holes are drilled on the wheel rim to provide installation points for other parts. Since a large number of holes are required, the drilling process often takes a lot of time. The Chinese patent "CN202222537163.6" discloses "a drilling device for processing bicycle rims that is easy to clamp". It can clamp and fix the rim through a linkage turntable, a movable clamping rod and other structures, and can adapt to rims of different sizes. However, it can only drill a single position at a time, and in some rims, the vacancies are not all in a single direction, and sometimes they are at a certain angle to the radial direction of the rim. In this way, the staggered arrangement of reinforcement strips can be achieved through mounting holes at different angles. In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0041] For details, see Figure 1-6 This embodiment provides an efficient wheel rim drilling device, including a base 31, a first lifting drive member 33, a fixing mechanism 10, and multiple sets of drilling mechanisms 20. The multiple sets of drilling mechanisms 20 are arranged around the fixing mechanism 10. The first lifting drive member 33 is arranged on the base 31. The fixing mechanism 10 is arranged at the driving end of the first lifting drive member 33. The first lifting drive member 33 is suitable for driving the fixing mechanism 10 to rise and fall.

[0042] For details, see Figure 5 The drilling mechanism 20 includes a first fixed seat 21, a support frame 23, a second fixed seat 22, a second lifting drive member 24, a first linear drive member 25 and a drilling machine body 28; the support frame 23 is arranged on the first fixed seat 21, the second fixed seat 22 is rotatably arranged on the support, the second lifting drive member 24 is arranged on the first fixed seat and its driving end is rotatably connected to one end of the second fixed seat 22, the first linear drive member 25 and the drilling machine body 28 are both arranged on the second fixed seat 22, and the first linear drive member 25 is suitable for driving the drilling machine body 28 to approach or move away from the fixing mechanism 10;

[0043] In the above scheme, the worker can place the wheel rim to be processed on the fixing mechanism 10, and the wheel rim is fixed by the fixing mechanism 10, so that the subsequent drilling mechanism 20 can realize stable drilling; wherein the first lifting driving part 33 can drive the fixing mechanism 10 to lift to adjust the height of the wheel rim; the first linear driving part 25 can drive the drilling machine body 28 to approach the fixing mechanism 10 and act on the wheel rim to drill the wheel rim; when different angle drilling needs to be realized, the second lifting driving part 24 drives one end of the second fixing seat 22 to lift, and then the second fixing seat 22 rotates on the support frame 23 at a certain angle, at this time the orientation of the drilling machine body 28 changes, and the first linear driving part 25 can only drive the drilling machine body 28 to move linearly, and the height of the wheel rim is adjusted by the first lifting driving part 33, that is, different drilling angles can be realized, and multi-angle hole processing can be realized; the first lifting driving part 33 is further arranged below the fixing mechanism 10, so that the lifting driving mechanism does not need to be arranged for each drilling mechanism 20, thereby the arrangement of the driving mechanism can be effectively saved, and the cost is effectively reduced.

[0044] Specifically, the first sliding rail 26 and the first sliding block 27 slidingly arranged on the first sliding rail 26 are arranged on the second fixing seat 22, and the drilling machine body 28 is arranged on the first sliding block 27, and the driving end of the first linear driving part 25 is connected with the first sliding block 27 to drive the first sliding block 27 to slide on the first sliding rail 26.

[0045] In the above scheme, the first linear driving part 25 is used to drive the first sliding block 27 to move, and the drilling machine body 28 is arranged on the first sliding block 27, so that the drilling machine body 28 can move with the first sliding block 27 to realize drilling of the wheel rim; the sliding rail can limit and guide the sliding block, so that the movement of the drilling mechanism 20 body is more stable.

[0046] In some embodiments, the first linear driving part 25 can be a driving cylinder or a linear driving motor.

[0047] Specifically, the fixing mechanism 10 includes a workbench 30, a driving module 11, and a plurality of clamping assemblies 12 connected with the driving module 11, and the plurality of clamping assemblies 12 are arranged at equal angles around the driving module 11.

[0048] Further, the clamping assembly 12 includes a second sliding rail 121, a second sliding block 122, a clamping jaw 13, and a lead screw 123; the second sliding rail 121 is arranged on the workbench 30, the second sliding block 122 is slidingly arranged on the second sliding rail 121, the clamping jaw 13 is arranged on the second sliding block 122, and the lead screw 123 is arranged through the second sliding block 122 and threadedly cooperates with the second sliding block 122.

[0049] Furthermore, the driving module 11 is adapted to drive the screw rod 123 of each clamping assembly 12 to rotate so as to drive the plurality of second sliders 122 to move closer to or away from each other;

[0050] In the above scheme, when the driving module 11 is started, it can drive the screw rod 123 to rotate. The screw rod 123 is threadedly matched with the second slider 122, so the rotational motion of the screw rod 123 can be converted into a linear motion of the second slider 122 moving along the axial direction of the screw rod 123. The second slider 122 moves along the axial direction of the screw rod 123, and then the multiple clamping jaws 13 can move closer or farther away from each other to achieve the tightening or support fixation of the wheel rim; the position of the second slider 122 in this scheme can be flexibly adjusted, so it can be suitable for the fixation of wheel rims of various sizes, effectively improving its compatibility; at the same time, a group of driving modules 11 can simultaneously drive the adjustment of multiple clamping components 12, effectively saving the setting of the driving mechanism, reducing costs, and at the same time improving the consistency of the actions between the multiple clamping components 12.

[0051] For details, see Figure 6 , the driving module 11 includes a rotating driving member 111, a first gear 112 and a plurality of second gears 113;

[0052] Furthermore, the first gear 112 is rotatably mounted on the workbench 30 and coaxially connected to the driving end of the rotary drive member 111. The rotary drive member 111 is used to drive the first gear 112 to rotate. The second gear 113 is coaxially arranged with the screw rod 123 and meshes with the first gear 112.

[0053] In the above scheme, the rotating driving member 111 can drive the first gear 112 to rotate, and the second gear 113 engages with the first gear 112 and can then rotate under the drive of the first gear 112. The rotation of the second gear 113 can drive the screw rod 123 to rotate, and finally the second slider 122 is moved along the axial direction of the screw rod 123; this scheme adopts the first gear 112 to drive multiple second gears 113, and thus can synchronously realize the adjustment of multiple clamping components 12, thereby improving the action consistency of multiple adjustment components.

[0054] In some embodiments, the first gear 112 and the second gear 113 may be bevel gears, that is, the rotating circular surface can be switched in this way, and the horizontal rotating surface can be converted into a vertical rotating surface; but it can be understood that the use of gears to achieve the switching of the rotating surface is a relatively mature technology in this field, and other methods can also be used for switching and adjustment, and this embodiment does not limit this.

[0055] For details, see Figure 3-4 , the clamping jaw 13 is detachably connected to the second slider 122;

[0056] In the above solution, the clamping jaw 13 and the second slider 122 are connected in a detachable manner, so that when a problem occurs with a single clamping jaw 13, it can be disassembled, replaced and maintained; in addition, the appropriate clamping jaw 13 can be selected for replacement according to different wheel rim shapes to improve the stability of the wheel rim.

[0057] Furthermore, a first mounting hole (not shown in the figure) is provided on the second slider 122;

[0058] Specifically, the clamping jaw 13 is L-shaped and includes a fixing portion 131 and a clamping jaw portion 132. The fixing portion 131 is provided with a waist-shaped hole 133 along its length direction;

[0059] In the above scheme, during installation, the waist-shaped hole 133 is aligned with the first mounting hole, and then locked by a fixing mechanism 10 such as a fixing screw to fix the clamp 13 and the second slider 122; the worker can fine-tune the installation position of the clamp 13 through the waist-shaped hole 133, thereby making the actual assembly process more flexible and allowing for a better fit during subsequent clamping.

[0060] Specifically, a limiting groove 124 is provided on the second slider 122 , the first mounting hole is provided in the limiting groove 124 , and the fixing portion 131 is adapted to be fixed to the bottom of the limiting groove 124 ;

[0061] In the above solution, the limiting groove 124 can limit the fixing portion 131, thereby further improving the assembly stability of the clamping jaw 13 and the first slider 27, and at the same time helping the installation portion to quickly achieve positioning, thereby improving assembly efficiency.

[0062] For details, see Figure 1 , a limiting column 32 is provided between the base 31 and the first fixing seat 21;

[0063] In the above solution, the limiting column 32 can play a limiting and guiding role in the lifting and lowering action of the first fixing seat 21, thereby making the lifting and lowering of the first fixing seat 21 more stable and ensuring the accuracy of the processing process.

[0064] In some embodiments, the first lifting drive member 33 and the second lifting drive member 24 may be lifting cylinders or other driving mechanisms that can drive lifting, and this application does not limit this.

[0065] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application fall within the scope of the technical solution of the present application.
