Description

Technical Field

[0001] The present invention relates to the technical field of drill bit processing, and more particularly, to a double-sided support mechanism and a grinding device for grinding drill bits. Background Art

[0002] In the field of drill bit manufacturing, especially during the processing of micro drill bits, the diameter grinding of the drilling part is a key process. However, under the existing technical conditions, this process faces many challenges.

[0003] First of all, for micro drill bits with a small diameter, due to the limitation of their structural dimensions, deformation is likely to occur during grinding, resulting in the drill bit not achieving the expected geometric accuracy and surface quality. This not only affects the performance of the drill bit but also increases the rejection rate, bringing additional costs to production.

[0004] Secondly, during the rough grinding stage, the concentricity between the drilling part and the shank part often fails to reach an ideal level, and there is a certain offset between the axes. This offset causes the drilling part to wobble / swing during grinding, thereby affecting the consistency and accuracy of grinding. It will lead to uneven wear of each part of the drill bit, further exacerbating the deviation in the shape and size of the drill bit, and having an adverse impact on the quality of the final product. Summary of the Invention

[0005] The present invention provides a double-sided support mechanism and a grinding device for grinding drill bits, aiming to improve at least one of the above technical problems.

One side of the notch is provided with a first support portion for supporting the drilling portion. The other side of the notch is hinged to the second hinge seat, and the second hinge seat is provided with a second support portion for supporting the drilling portion.

[0018] On one side of the first hinge seat away from the notch, an inclined avoidance portion is provided so that when the first hinge seat is in the first away position, the hinge position of the second hinge seat can be closer to the limiting portion.

The stable support environment not only reduces the deformation risk of the micro drill bit due to its small diameter, but also enables the surface of the drilling part to obtain a more uniform and finer grinding effect, thereby improving the grinding quality. Higher machining accuracy means a lower scrap rate and reduces the need for rework, which not only improves the overall production efficiency but also reduces the manufacturing cost.

Detailed implementation mode

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the present invention claimed, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0045] Example 1. Consisting of Figures 1 to 10 As shown in Figures 1 to 10 , an embodiment of the present invention provides a double-sided support mechanism 35 for grinding a drill bit, which is adapted to support the drilling part of the drill bit from two directions during the grinding process of the drill bit diameter. Among them, the drill bit includes a drill shank part, a drilling part, and a drill neck located between the drill shank part and the drilling part. The double-sided support mechanism 35 includes a fixed component 12, a first support component 13, a second support component 17, and a driving component 20. The fixed component 12 is used to engage with the outside.

[0046] The first support component 13 includes a first hinge seat 1 hinged to the fixed component 12, and a first elastic member 2 engaged with the first hinge seat 1. The first hinge seat 1 is adapted to move between a first support position for supporting the drilling part and a first away position away from the drilling part. The first elastic member 2 is adapted to provide a first support force for the first hinge seat 1 that can cause the first hinge seat 1 to move towards the first support position or the first away position.

[0047] The second support component 17 includes a second hinge seat 9 hinged to the first hinge seat 1, and a second elastic member 8 engaged with the second hinge seat 9. The second hinge seat 9 is adapted to move between a second support position for supporting the drilling part and a second away position away from the drilling part. The second elastic member 8 is adapted to provide a second support force for the second hinge seat 9 that can cause the second hinge seat 9 to move towards the second support position or the second away position.

[0048] The driving component 20 is adapted to provide a third support force for the first hinge seat 1 that can overcome the first support force. Preferably, the driving component 20 is configured as an element with a telescopic structure such as a cylinder, an oil cylinder, or a linear motor.

[0049] The fixed component 12 is provided with a limiting portion 6. The second hinge seat 9 abuts against the limiting portion 6. The limiting portion 6 is adapted to provide a fourth support force for the second hinge seat 9 that can overcome the second support force. The combined action of the second support force and the third support force is configured to be able to drive the second hinge seat 9 towards the second away position when the first hinge seat 1 moves towards the first away position, and to be able to drive the second hinge seat 9 towards the second support position when the first hinge seat 1 moves towards the first support position.

[0050] The solution of the bilateral support mechanism 35 supporting the drill bit from two directions can effectively reduce the shaking phenomenon caused by axis deviation and improve the stability of the drill bit during the grinding process. The stable support environment not only reduces the deformation risk of the micro drill bit due to its small diameter, but also enables the surface of the drilling part to obtain a more uniform and finer grinding effect, thus improving the grinding quality. Higher processing accuracy means a lower rejection rate and reduces the need for rework, which not only improves the overall production efficiency but also reduces the manufacturing cost.

[0051] Based on the above embodiments, in an alternative embodiment of the present invention, as Figures 1 to 4 shown, the fixing component 12 includes a first fixing seat 4, a second fixing seat 5 and a third fixing seat 3 joined to the first fixing seat 4. The second fixing seat 5 is hinged to the first fixing seat 4 and is configured to be fixed to the first fixing seat 4 at different angles. The limiting portion 6 is provided on the second fixing seat 5 to adjust the position of the limiting portion 6. The third fixing seat 3 is adapted to limit the rotation angle of the first hinge seat 1 on the first fixing seat 4. Preferably, the fixing component 12 further includes a sliding seat, and the first fixing seat 4 is slidably coupled to the sliding seat to be adapted to move the first support component 13 and the second support component 17 along the axis direction of the drill bit. The limiting portion 6 is configured as an inclined surface. The second support component 17 further includes a roller 7 rotatably joined to the second hinge seat 9. The roller 7 is adapted to abut against the limiting portion 6.

[0052] Specifically, through the first fixing seat 4, the support positions of the first support component 13 and the second support component 17 on the drilling part can be adjusted to cooperate with drill bits of different length specifications. Through the second fixing seat 5, accurate positioning can be provided for the second hinge seat 9 so that it accurately abuts against the side surface of the drilling part. The second fixing seat 5 is hinged to the first fixing seat 4 and can adjust the angle in the rotation direction, thereby providing positioning at different positions and can also adapt to more specifications of drill bits.

[0053] One end of the third fixing seat 3 is hinged to the first fixing seat 4, and the other end is slidably joined to the first hinge seat 1 through an oblong hole, thereby limiting the rotation range of the first hinge seat 1. Through the third fixing seat 3, it is possible to prevent the first hinge seat 1 from applying too much force to the drilling part and prevent the drilling part from deforming, greatly improving the accuracy of the drilling part.

[0054] Based on the above embodiments, in an alternative embodiment of the present invention, as Figures 1 to 4 shown, the limiting portion 6 is located on the side of the first hinge seat 1 away from the first support position, so that the first hinge seat 1 can approach the limiting portion 6 when moving towards the first far position.

[0055] Specifically, when moving towards the first far position, it can drive the second hinge seat 9 to move, so that the roller 7 rolls along the inclined surface to adjust the included angle between the first hinge seat 1 and the second hinge seat 9, and enable the second hinge seat 9 to move towards the second far position.

[0056] Through the integrated linkage structure of the first hinge seat 1, the first elastic member 2, the second hinge seat 9, the second elastic member 8, the driving assembly 20 and the limiting portion 6, the first hinge seat 1 and the second hinge seat 9 can be synchronously close to and support the drilling portion in a relatively small space, or synchronously move away from the drilling portion, so as to realize bilateral support for the drilling portion. It can be understood that none of these five components of the integrated linkage structure can be missing. Without any one of the components, bilateral support for the drilling portion cannot be achieved. Therefore, these five technical features belong to the technical features that support each other functionally and have an interaction relationship as stipulated in the Examination Guidelines, and should be considered and evaluated as a whole.

[0057] Based on the above embodiments, in an alternative embodiment of the present invention, as Figures 1 to 4 shown, a notch 15 is provided on one side of the first hinge seat 1 facing the first support position. A first support portion 14 for supporting the drilling portion is provided on one side of the notch 15. The other side of the notch 15 is hinged to the second hinge seat 9, and the second hinge seat 9 is provided with a second support portion 16 for supporting the drilling portion. An inclined avoidance portion 18 is provided on the side of the first hinge seat 1 away from the notch 15, so that when the first hinge seat 1 is in the first far position, the hinge position of the second hinge seat 9 can be closer to the limiting portion 6.

[0058] In this embodiment, a notch 15 is provided to accommodate the support member. In other embodiments, the first support member 11 and the second support member 10 can also be respectively installed on the upper surfaces of the first hinge seat 1 and the second hinge seat 9 without providing the notch 15. The notch 15 is not an essential technical feature of the present invention, but an improved technical feature, which can reduce the thickness of the overall structure to avoid other structures of the device. In other embodiments, avoidance can be achieved by means of overall movement without the need to be designed into a flattened structure.

[0059] Based on the above embodiments, in an alternative embodiment of the present invention, as Figures 2 to 4As shown, the first support assembly 13 further includes a first support member 11 detachably engaged with the first hinge seat 1. The first support member 11 is provided with a first support portion 14 for supporting the drilling portion. The second support assembly 17 further includes a second support member 10 detachably engaged with the second hinge seat 9. The second support member 10 is provided with a second support portion 16 for supporting the drilling portion. The first support portion 14 and the second support portion 16 are adapted to support the drilling portion from different angles.

[0060] The first support member 11 is configured to be engaged with the second hinge seat 9 in a position adjustable along a direction perpendicular to the support direction of the first support portion 14. The second support member 10 is configured to be engaged with the second hinge seat 9 in a position adjustable along the support direction of the second support portion 16 and a direction perpendicular to the support direction.

[0061] In this embodiment, the first support portion 14 and the second support portion 16 are respectively mounted on the first hinge seat 1 and the second hinge seat 9 through the first support member 11 and the second support member 10. Preferably, the first support member 11 can adjust the length extending from the first hinge seat 1 along the support direction. The second support member 10 can adjust the length extending from the second hinge seat 9 along the support direction, and can also adjust the position along a direction perpendicular to the support direction, so as to be adapted to drills of different diameters, and can be adjusted when the support portion is worn, ensuring that the support portion can always abut against the drilling portion.

[0062] In other embodiments, the first support portion 14 and the second support portion 16 may be integrally designed with the first hinge seat 1 and the second hinge seat 9 without installing the first support member 11 and the second support member 10, and the present invention does not make specific limitations thereon.

[0063] On the basis of the above embodiments, in an alternative embodiment of the present invention, the first support force is configured to be able to drive the first hinge seat 1 to move towards the first far position. The third support force is configured to be able to drive the first hinge seat 1 to move towards the first support position.

[0064] The second support force is configured to be able to drive the second hinge seat 9 to move towards the second far position. The fourth support force is configured to be able to drive the second hinge seat 9 to move towards the second support position.

[0065] Preferably, the first elastic member 2 is a tensile elastic member and is engaged between the fixed assembly 12 and the first hinge seat 1. The second elastic member 8 is a tensile elastic member and is engaged between the first hinge seat 1 and the second hinge seat 9.

[0066] As Figures 1 to 4As shown, the second fixing seat 5 is disposed between the first hinge seat 1 and the second hinge seat 9. Both the first elastic member 2 and the second elastic member 8 are tension springs, and both are used to pull the hinge seat away from the drilling part.

[0067] The driving assembly 20 is used to drive the first hinge seat 1 to rotate towards the drilling part. The second hinge seat 9 moves along with the first hinge seat 1. During the rotation process, the second fixing seat 5 moves away from the first hinge seat 1, driving one end of the second hinge seat 9 away from the first hinge seat 1 and the other end to rotate towards the drilling part.

[0068] When the driving assembly 20 releases the first hinge seat 1, the first hinge seat 1 moves away from the drilling part. At this time, the first hinge seat 1 approaches the second fixing seat 5, and one end of the second hinge seat 9 always fits on the second fixing seat 5 under the action of the second elastic member 8, so that the other end of the second hinge seat 9 rotates away from the drilling part.

[0069] In other embodiments, the tension spring can be replaced with a torsion spring, and the above effects can also be achieved, and it is not necessary to use a tensile elastic member.

[0070] In an alternative embodiment, the first elastic member 2 can be set as a compression spring, or the stretching direction of the tension spring can be changed so that the driving direction of the first elastic member 2 is opposite to the solution of this embodiment, and is used to drive the first hinge seat 1 to rotate towards the first support position. At this time, the driving direction of the driving assembly 20 also needs to be modified to the opposite direction in this embodiment to drive the first hinge seat 1 to rotate towards the direction of the first away position.

[0071] Similarly, the second elastic member 8 can also be set as a compression spring, or the stretching direction of the tension spring can be changed so that the driving direction of the second elastic member 8 is opposite to the direction of this embodiment, and is used to drive the second hinge seat 9 to rotate towards the second support position. At this time, the installation position of the limiting portion 6 also needs to be changed, and the limiting portion 6 is installed on the side of the second hinge seat 9 away from the first hinge seat 1, rather than between the first hinge seat 1 and the second hinge seat 9.

[0072] At this time, when the first hinge seat 1 rotates towards the drilling part, the second hinge seat 9 moves away from the limiting portion 6 and synchronously rotates towards the drilling part under the drive of the second elastic member 8. When the first hinge seat 1 rotates away from the drilling part, the second hinge seat 9 approaches the limiting portion 6 and synchronously rotates away from the drilling part under the extrusion of the limiting portion 6. Thus, the first support assembly 13 and the second support assembly 17 are synchronously supported and moved away from the drilling part in a small space.

[0073] Embodiment 2, such as Figures 1 to 10As described above, the present application further provides a grinding device for grinding a drill bit, which includes a base 22, a first drill shank fixing mechanism 28 engaged with the base 22 and adapted to engage with the drill shank of the drill bit, a bilateral support mechanism 35 for supporting the cutting portion of the drill bit as described in any section of Embodiment 1, and a drill bit grinding mechanism 19 for grinding the cutting portion.

[0074] During the rough grinding process of the cutting portion of the grinding device of the present invention, the bilateral support mechanism 35 always abuts against the cutting portion to provide support for the cutting portion, avoiding deformation or shaking of the cutting portion during the grinding process, and greatly improving the grinding quality of the cutting portion.

[0075] On the basis of the above embodiments, in an optional embodiment of the present invention, as Figures 5 to 10 shown, the grinding device further includes a second drill shank fixing mechanism 21. The second drill shank fixing mechanism 21 includes a first clamping assembly 24 for driving the drill bit to rotate, and a second clamping assembly 27 and a third clamping assembly 23 for clamping the drill shank to the first clamping assembly 24. Preferably, the first clamping assembly 24 includes a first clamping wheel 25 and a first driving member 26 for driving the first clamping wheel 25 to rotate. The second clamping assembly 27 includes a first clamping seat 30 movably engaged with the base 22, a second clamping wheel 29 rotatably engaged with the first clamping seat 30, and a second driving member 31 for driving the first clamping seat 30 to move. The second driving member 31 is adapted to drive the second clamping wheel 29 to approach or move away from the first clamping wheel 25. The third clamping assembly 23 includes a second clamping seat 32 movably engaged with the base 22 and a third driving member 34 for driving the second clamping seat 32. The second clamping seat 32 is provided with a third support portion 33 for abutting against the drill shank. A clamping space for accommodating the drill shank is formed between the first clamping wheel 25, the second clamping wheel 29 and the third support portion 33.

[0076] Specifically, through the arrangement of the first clamping wheel 25, the second clamping wheel 29 and the second clamping seat 32, not only can the shank be stably clamped to avoid deformation or shaking of the shank, but also the drill bit can be driven to rotate, so that the drill bit can be evenly ground at various angles.

[0077] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
