Description

Technical Field

[0001] The present application relates to the technical field of bicycle rim processing equipment, and in particular to a bicycle rim drilling device. Background Art

[0002] A bicycle, also known as a bike or a bicycle, is usually a small two-wheeled land vehicle. When people ride on it, they use pedals as power. It is a green and environmentally friendly means of transportation.

[0003] Bicycle rims are one of the most important parts of a bicycle. During production, they need to be shaped and then drilled to provide mounting points for other components.

[0004] Chinese patent "CN219786621U" discloses "a bicycle rim drilling machine", which adopts a more traditional fixing method to fix the rim, that is, the clamping block is driven to move by the clamping cylinder to finally achieve the support and fixation of the rim; it is understandable that when different rims are produced, the external curvature of the rim will change. At this time, if the same clamping block is still used for support, there will be a certain gap in the support part. If the stability of the clamping needs to be ensured, the clamping force needs to be further increased, which may have a certain impact on the appearance of the rim. Utility Model Content

[0005] The purpose of this application is to provide a bicycle rim drilling device to solve at least one of the above technical problems.

[0006] In order to solve the above technical problems, the present application provides a bicycle rim drilling device, comprising a positioning mechanism and a drilling mechanism provided on one side of the positioning mechanism, wherein the positioning mechanism is used to fix the rim, and the drilling mechanism is used to drill holes in the rim;

[0007] The positioning mechanism includes a base, a first drive assembly, and four groups of positioning assemblies slidably disposed on the base. The four groups of positioning assemblies are arranged in pairs opposite to each other, and two groups of the positioning assemblies are adapted to slide in a first direction, and the other two groups of the positioning assemblies are adapted to slide in a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0008] The first driving assembly is adapted to drive the positioning assembly to slide on the base;

[0009] The positioning assembly includes a sliding block, a fixing seat, a first positioning rod and a second positioning rod; the sliding block is slidably mounted on the base, the fixing seat is mounted on the sliding block, the first positioning rod is fixedly mounted on the fixing seat, two second positioning rods are provided and are respectively located on both sides of the first positioning rod and are rotatably adjusted on the fixing seat, and the first positioning rod and the second positioning rod are suitable for abutting against the inner wall of the rim to position the rim;

[0010] In the above implementation process, the staff can install the wheel rim to be drilled onto the positioning mechanism, the positioning mechanism fixes the wheel rim to keep the wheel rim stable, and then drills the wheel rim through the drilling mechanism; when positioning, the four positioning components are in a relatively close position, and the wheel rim is placed to circle the four positioning components within the range of the wheel rim, and then the first driving member is started to drive the four positioning components to move, and after the positioning components move, they drive the positioning rods to abut against the inner wall of the wheel rim, thereby fixing the wheel rim from the inside to ensure the problem of subsequent drilling process; in this solution, each positioning component includes a fixed first positioning rod and two rotatable second positioning rods, and the first positioning rod is used as a As an adjustment reference for the second positioning rod, the second positioning rod can be rotated to adjust the angle between it and the first positioning rod. In this way, when fixing rims of different sizes, the abutment virtual circle formed by the first positioning rod and the second positioning rod can be changed by adjusting the rotation angle of the second positioning rod, so that the positioning mechanism can better fix the rim. In addition, compared with the method of using the entire clamping block, the present solution uses multiple positioning rods to avoid air in more positions of the rim, thereby having less impact on drilling and reducing the occurrence of the situation where the drilling point is affected by the clamping position being too large. This solution not only improves the fixation of the rim drilling, but also improves the fixation stability of different rims.

[0011] Preferably, the first positioning rod and the second positioning rod each include a rod body and an anti-slip member;

[0012] The anti-slip member is provided at one end of the rod body close to the wheel rim;

[0013] In the above implementation process, the rod body provides basic structural strength and supports the anti-slip part. The anti-slip part abuts against the inner wall of the rim to increase the relative friction between the rim and the positioning rod, thereby further improving the fixing stability of the positioning mechanism on the rim.

[0014] Preferably, the anti-slip member is made of anti-slip silica gel, and anti-slip stripes are provided on the outer wall of the anti-slip member;

[0015] In the above implementation process, the anti-slip part is made of anti-slip silicone, which can increase the relative friction between the anti-slip part and the inner wall of the rim. At the same time, silicone has a certain deformation ability, so it can achieve better fit to the inner wall of the rim. Further setting anti-slip stripes can further increase the relative friction.

[0016] Preferably, the first driving assembly includes a rotary driving member, a first gear, a second gear and a screw;

[0017] The first gear is provided at the driving end of the rotary drive member, and the rotary drive member is used to drive the first gear to rotate. The screw is fixedly connected to the second gear and the second gear is meshed with the first gear. The screw is passed through the sliding block and is threadedly engaged with the sliding block.

[0018] Wherein, the second gear and the screw rod are respectively provided with four and are arranged corresponding to the positioning assembly;

[0019] In the above implementation process, the rotating drive member can drive the first gear to rotate. Since the second gear is engaged with the first gear, the rotation of the first gear will drive the second gear to rotate. The screw rod is connected to the second gear, so the rotation of the second gear will drive the screw rod to rotate. The screw rod is threaded with the sliding block, so when the screw rod rotates, it can drive the sliding block to move back and forth along the axial direction of the screw rod, thereby moving the positioning assembly.

[0020] Preferably, a groove is provided on the base, and the sliding block, the screw rod, the first gear and the second gear are all provided in the groove;

[0021] In the above implementation process, a groove is further provided on the base to provide a setting space for the sliding block, the screw rod, the first gear and the second gear, so that more space on the top surface of the base can be left for fixing the rim, which can effectively avoid the components of the positioning mechanism from interfering with the rim, making the material taking and releasing process smoother.

[0022] Preferably, a receiving groove is provided on the fixing seat, and one end of the second positioning rod extends into the receiving groove;

[0023] It also includes a locking bolt, which penetrates the accommodating groove and the second positioning rod and is suitable for fixing the second positioning rod on the fixing seat;

[0024] In the above implementation process, the rotation angle of the second positioning rod is adjustable. When it is necessary to adjust the angle between the second positioning rod and the first positioning rod, the locking bolt is first loosened. At this time, the second positioning rod can be rotated. After rotating to the appropriate angle, the locking bolt is tightened to fix the position of the second positioning rod, thereby completing the adjustment action.

[0025] Preferably, the drilling mechanism includes a slide rail, a sliding seat, a linear drive member, and a drilling machine body;

[0026] The sliding seat is arranged on the slide rail, the drilling machine body is arranged on the sliding seat, and the driving end of the linear driving member is fixedly connected to the sliding seat and is suitable for driving the sliding seat to move;

[0027] In the above implementation process, the linear drive member drives the sliding seat to slide on the slide rail, and then drives the drilling machine body to approach the rim. The drilling machine body acts on the rim to realize the drilling action of the rim. After the drilling is completed, the linear drive member drives the sliding seat away from the rim to achieve air avoidance.

[0028] Compared with the prior art, the beneficial effect of the present application is that each positioning assembly in the present solution includes a fixed first positioning rod and two rotatable second positioning rods, the first positioning rod serves as an adjustment reference for the second positioning rod, and the second positioning rod can adjust the angle between it and the first positioning rod by rotation. In this way, when fixing rims of different sizes, by adjusting the rotation angle of the second positioning rod, the abutment virtual circle formed by the first positioning rod and the second positioning rod can be changed, thereby enabling the positioning mechanism to better fix the rim; in addition, the present solution adopts a method of multiple positioning rods compared to the method of adopting the entire clamping block, which can avoid air in more positions of the rim, thereby having less impact on drilling, and reducing the occurrence of situations where the drilling point is affected by the clamping position being too large; the present solution can not only improve the fixation of rim drilling, but also improve the fixation stability of different rims.

[0041] Example

[0042] Bicycle rims are one of the most important parts of bicycles. During production, they need to be shaped and then drilled to provide mounting points for other parts. Chinese patent "CN219786621U" discloses "a bicycle rim drilling machine" that uses a more traditional fixing method to fix the rims, that is, a clamping cylinder drives the clamping block to move, ultimately achieving the clamping and fixing of the rims. It is understandable that when different rims are produced, the external curvature of the rims will change. At this time, if the same clamping block is still used for clamping, there will be a certain gap in the clamping part. If the clamping stability needs to be guaranteed, the clamping force needs to be further increased, which may have a certain impact on the appearance of the rims. In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0043] For details, see Figure 1-6 This embodiment provides a bicycle rim drilling device, comprising a positioning mechanism 10 and a drilling mechanism provided on one side of the positioning mechanism 10, wherein the positioning mechanism 10 is used to fix the rim, and the drilling mechanism is used to drill holes in the rim;

[0044] Specifically, the positioning mechanism 10 includes a base 11, a first drive assembly, and four groups of positioning assemblies 12 slidably disposed on the base 11. The four groups of positioning assemblies 12 are arranged in pairs opposite to each other, and two groups of positioning assemblies 12 are adapted to slide in a first direction, and the other two groups of positioning assemblies 12 are adapted to slide in a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0045] Furthermore, the first driving assembly is adapted to drive the positioned assembly to slide on the base 11;

[0046] Specifically, the positioning assembly 12 includes a sliding block 121, a fixing seat, a first positioning rod 123, and a second positioning rod 124; the sliding block 121 is slidably mounted on the base 11, the fixing seat is mounted on the sliding block 121, the first positioning rod 123 is fixedly mounted on the fixing seat, and two second positioning rods 124 are provided and are respectively located on both sides of the first positioning rod 123 and are rotatably adjustable on the fixing seat. The first positioning rod 123 and the second positioning rod 124 are adapted to abut against the inner wall of the rim to position the rim;

[0047] In the above scheme, the staff can install the wheel rim to be drilled onto the positioning mechanism 10, the positioning mechanism 10 fixes the wheel rim to keep the wheel rim stable, and then drills the wheel rim through the drilling mechanism; when positioning, the four positioning components 12 are in a relatively close position, and the wheel rim is placed when the four positioning components 12 are circled within the range of the wheel rim, and then the first driving member is started to drive the four positioning components 12 to move, and after the positioning component 12 moves, it drives the positioning rod to abut against the inner wall of the wheel rim, thereby fixing the wheel rim from the inside to ensure the problem of subsequent drilling process; in this scheme, each positioning component 12 includes a fixed first positioning rod 123 and two rotatable second positioning rods 124, and the first positioning rod 123 is used as a As an adjustment reference for the second positioning rod 124, the second positioning rod 124 can adjust the angle between it and the first positioning rod 123 by rotation. In this way, when fixing rims of different sizes, the abutment virtual circle formed by the first positioning rod 123 and the second positioning rod 124 can be changed by adjusting the rotation angle of the second positioning rod 124, so that the positioning mechanism 10 can achieve better fixation of the rim; in addition, compared with the method of using the entire clamping block, the present solution uses multiple positioning rods to avoid air in more positions of the rim, thereby having less impact on drilling and reducing the occurrence of the situation where the drilling point is affected by the clamping position being too large; this solution not only improves the fixation of the rim drilling, but also improves the fixation stability of different rims.

[0048] For details, see Figure 6 The first positioning rod 123 and the second positioning rod 124 both include a rod body 1241 and an anti-slip member 1242;

[0049] Furthermore, the anti-slip member 1242 is provided at one end of the rod body 1241 close to the rim;

[0050] In the above scheme, the rod body 1241 provides basic structural strength and provides support for the anti-slip part 1242. The anti-slip part 1242 abuts against the inner wall of the rim to increase the relative friction between the rim and the positioning rod, thereby further improving the fixing stability of the positioning mechanism 10 on the rim.

[0051] Furthermore, in some embodiments, see 5-6, the end of the rod body 1241 is spherical; it is understandable that the spherical structure can achieve a more stable installation or other connection of the anti-slip part 1242, while also increasing the contact range of the end face of the rod body 1241 with the inner ring of the rim, and the second positioning rod 124 can still better abut against the inner ring of the rim after adjusting to a certain angle.

[0052] Furthermore, the anti-slip member 1242 is made of anti-slip silicone and has anti-slip stripes on the outer wall of the anti-slip member 1242;

[0053] In the above solution, the anti-slip part 1242 is made of anti-slip silicone, which can increase the relative friction between the anti-slip part 1242 and the inner wall of the rim. At the same time, silicone has a certain deformation ability, so it can achieve a better fit with the inner wall of the rim. Further setting anti-slip stripes can further increase the relative friction.

[0054] For details, see Figure 4 , the first driving assembly includes a rotary driving member 13, a first gear 14, a second gear 15 and a screw rod 16;

[0055] Furthermore, the first gear 14 is provided at the driving end of the rotary drive member 13, and the rotary drive member 13 is used to drive the first gear 14 to rotate. The screw rod 16 is fixedly connected to the second gear 15, and the second gear 15 is meshed with the first gear 14. The screw rod 16 is passed through the sliding block 121 and is threadedly engaged with the sliding block 121.

[0056] Among them, there are four second gears 15 and four screw rods 16 respectively and they are arranged corresponding to the positioning assembly 12;

[0057] In the above scheme, the rotating driving member 13 can drive the first gear 14 to rotate. Since the second gear 15 is engaged with the first gear 14, when the first gear 14 rotates, it will drive the second gear 15 to rotate. The screw rod 16 is connected to the second gear 15, so when the second gear 15 rotates, it will drive the screw rod 16 to rotate. The screw rod 16 is threadedly matched with the sliding block 121, so when the screw rod 16 rotates, it can drive the sliding block 121 to reciprocate along the axial direction of the screw rod 16, thereby moving the positioning component 12.

[0058] In some embodiments, the rotary driving member 13 may be a rotary motor.

[0059] Specifically, a groove 111 is provided on the base 11, and the sliding block 121, the screw rod 16, the first gear 14, and the second gear 15 are all provided in the groove 111;

[0060] In the above scheme, a groove 111 is further provided on the base 11 to provide a setting space for the sliding block 121, the screw rod 16, the first gear 14 and the second gear 15, so that more space on the top surface of the base 11 can be left for fixing the rim, which can effectively avoid the components of the positioning mechanism 10 from interfering with the rim, making the material taking and releasing process smoother.

[0061] For details, see Figure 5 , a receiving groove 1221 is provided on the fixing seat 122, and one end of the second positioning rod 124 extends into the receiving groove 1221;

[0062] Furthermore, it also includes a locking bolt 125, which penetrates the receiving groove 1221 and the second positioning rod 124 and is suitable for fixing the second positioning rod 124 on the fixing seat;

[0063] In the above scheme, the rotation angle of the second positioning rod 124 is adjustable. When it is necessary to adjust the angle between the second positioning rod 124 and the first positioning rod 123, the locking bolt 125 is first loosened. At this time, the second positioning rod 124 can be rotated. After rotating to the appropriate angle, the locking bolt 125 is tightened to fix the position of the second positioning rod 124, thereby completing the adjustment action.

[0064] For details, see Figure 1 , the drilling mechanism includes a slide rail 21, a sliding seat 22, a linear drive member 23, and a drilling machine body 24;

[0065] Furthermore, the sliding seat 22 is provided on the slide rail 21, the drilling machine body 24 is provided on the sliding seat 22, and the driving end of the linear driving member 23 is fixedly connected to the sliding seat 22 and is adapted to drive the sliding seat 22 to move;

[0066] In the above scheme, the linear drive member 23 drives the sliding seat 22 to slide on the slide rail 21, and then drives the drilling machine body 24 to approach the rim. The drilling machine body 24 acts on the rim to realize the drilling action of the rim. After the drilling is completed, the linear drive member 23 drives the sliding seat 22 away from the rim to achieve air avoidance.

[0067] In some embodiments, the linear drive member 23 may be a drive cylinder or a linear drive motor.

[0068] It should be noted that the drilling machine body 24 is a relatively mature technology in the existing technology, so its specific structure and working principle will not be further described in this application.

[0069] 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.
