Description

Technical Field

[0001] This utility model relates to the technical field of drill bit production equipment, and more specifically, to a drill bit grinding device and its grinding support mechanism. Background Technology

[0002] In modern industrial manufacturing, drill bits, as a common cutting tool, have always been an important part of machining technology in terms of design and manufacturing. The basic structure of a drill bit typically includes a shank for connecting to external equipment and a drilling section for drilling into the workpiece. With the development of industrial technology, the precision requirements for machined holes are becoming increasingly stringent, directly leading to strict requirements on the dimensional accuracy of drill bits. To meet these precision requirements, the drilling section of the drill bit must undergo fine grinding during the manufacturing process to ensure its dimensional accuracy and consistency.

[0003] In actual production, grinding the drill bit is not without challenges. During the grinding process, the drill bit may deform, often due to slight elastic or plastic changes in its structure caused by the grinding force. Furthermore, the vibration of the drill bit during grinding is a significant issue, potentially caused by unstable contact between the drill bit and the grinding equipment or insufficient balance within the drill bit itself. These deformations and vibrations not only reduce grinding efficiency but may also lead to substandard dimensional accuracy of the drill bit, thus affecting the quality and performance of the final product.

[0004] In the field of high-precision machining, even the slightest error can lead to a significant decline in product performance. Therefore, deformation and wobble during the grinding process of drill bits have become key factors restricting the improvement of drill bit performance. To solve these problems, there is an urgent need for more stable and precise grinding technology to reduce or eliminate deformation and wobble during drilling and improve the machining accuracy of drill bits.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1, by Figures 1 to 3 ,as well as Figure 6 As shown, this utility model embodiment provides a grinding support mechanism for a drill bit grinding device. The grinding support mechanism is adapted to support the drilling section of the drill bit during the drill bit diameter grinding process;

[0034] The grinding support mechanism includes a first fixing component 1, a first support component 2, a first drive component 3, and a second drive component 4. The first fixing component 1 is used to engage with an external object; the first support component 2 is movably engaged with the first fixing component 1; the first support component 2 is provided with a first support portion 11 for supporting the drilling portion of the drill bit; the first drive component 3 is engaged with the first fixing component 1; the first drive component 3 is configured to provide a driving force to the first support component 2 to drive the first support portion 11 to abut against the drilling portion; the second drive component 4 is engaged with the first fixing component 1; the second drive component 4 is configured to drive the first support component 2 to overcome the driving force of the first drive component 3 and move in a direction away from the drilling portion.

[0035] The grinding support mechanism of the drill bit grinding device of the present invention will not detach from the drill bit as the diameter of the drill bit decreases during the grinding process. The first driving component 3 always provides a driving force to the first support component 2, so that the first support component 2 always abuts against the drill bit during grinding, providing support for the drill bit and preventing deformation or shaking of the drill bit during the grinding process, which greatly improves the grinding quality of the drill bit.

[0036] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1As shown, the first support component 2 is hinged to the first fixed component 1; the first drive component 3 and the second drive component 4 are configured to drive the first support component 2 to rotate in opposite directions. Preferably, the middle part of the first support component 2 is hinged to the first fixed component 1; the first drive component 3 and the second drive component 4 are located on the same side of the first support component 2, and the first drive component 3 and the second drive component 4 are configured to apply force to the positions of the first support component 2 located on both sides of the hinge.

[0037] By placing the first drive assembly 3 and the second drive assembly 4 on the same side of the first support assembly 2, the first support part 11 can be avoided, making the area around the first support part 11 relatively open and preventing accidental collisions during the production process.

[0038] In other embodiments, the first support component 2 can be engaged with the first fixed component 1 in a sliding or swinging manner (i.e., the end is hinged to the first fixed component 1 instead of the middle), and can also switch between two positions abutting the drilling part and away from the drilling part. The present invention does not specifically limit this, as long as the first support component 2 has two working positions of support and away, and the first drive component 3 and the second drive component 4 are used to drive the first support component 2 to move toward the support position and toward the away position respectively, it falls within the protection scope of the present invention.

[0039] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 As shown, the first drive assembly 3 includes a first elastic element; the first elastic element is adapted to provide a driving force to the first support assembly 2 to drive the first support portion 11 to abut against the drilling portion. Preferably, the first drive assembly 3 further includes a first abutment 6 engaged between the first elastic element and the first support assembly 2, and a first preload 5 engaged on the side of the first elastic element away from the first abutment 6; the first preload 5 is adapted to adjust the elastic potential energy of the first elastic element;

[0040] In this embodiment, the first elastic element is a torsion spring, and its elastic potential energy can be adjusted by the first preload element 5. In other embodiments, the first elastic element may be a torsion spring, or a component such as a magnet that can drive the first support assembly 2 to move toward the drilling part; the present invention does not specifically limit this.

[0041] In this embodiment, the second driving component 4 is a telescopic member. The telescopic member can be a cylinder, hydraulic cylinder, linear motor, or other similar components. In other embodiments, the second driving component 4 can employ an electromagnetic structure, a traction rope, or other driving structure to drive the first support component 2. This invention does not impose specific limitations on this, as long as it can be used to drive the first support component 2 to move away from the drilling part.

[0042] The first drive assembly 3 ensures that the first support part 11 is always in contact with the drilling part, providing stable support and preventing the drilling part from shaking or deforming, thus greatly improving the grinding quality. The second drive assembly 4 drives the first support part 11 to avoid obstacles during loading and unloading.

[0043] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 As shown, the first support assembly 2 includes a first support seat 13 movably coupled to the first fixing assembly 1, and a first support member 12 coupled to the first support seat 13 that is adjustable back and forth along a first direction; the first support portion 11 is disposed on the first support member 12; preferably, the first fixing assembly 1 includes a first fixing seat 8 for engaging with an external object, a second fixing seat 9 coupled to the first fixing seat 8 that is adjustable back and forth along a second direction, and a third fixing seat 10 coupled to the second fixing seat 9 that is adjustable back and forth along a third direction; the first support seat 13 is coupled to the third fixing seat 10.

[0044] Specifically, the second direction is perpendicular to the third direction. The first support member 12 moves in an arc under the swing of the first support base 13. The first direction is approximately perpendicular to the first direction and the third direction. By adjusting the three degrees of freedom, the position of the first support part 11 can be precisely adjusted so that it accurately abuts against the drilling part.

[0045] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 As shown, the first driving component 3 further includes a first limiting member 7 engaged with the first fixing component 1; the first limiting member 7 is provided to abut against the first limiting portion of the first support component 2; the first limiting member 7 is configured to adjust the position of the first limiting portion to limit the first support component 2. Preferably, the first driving component 3 further includes a second limiting member 14 engaged with the first fixing component 1;

[0046] Specifically, the first limiting member 7 is used to limit the first support base 13; the second limiting member 14 is used to limit the first support member 12; through the first limiting member 7 and the second limiting member 14, it is possible to better prevent the first support part 11 from going beyond the support position and squeezing the drilling part into reverse deformation.

[0047] Example 2, by Figures 1 to 6 As shown, this application also provides a drill bit grinding device, which includes a first drill bit fixing mechanism 15 for engaging with the shank of the drill bit, a grinding support mechanism for supporting the drilling part of the drill bit as described in any paragraph of Embodiment 1, and a drill bit grinding mechanism 23 for grinding the drilling part.

[0048] In the process of grinding the drill bit, the present invention provides a drill bit grinding device. During the grinding process, a grinding support mechanism of the drill bit grinding device is always in contact with the drill bit to provide support for the drill bit, thereby preventing deformation or shaking of the drill bit during the grinding process and greatly improving the grinding quality of the drill bit.

Preferably, the second drill bit fixing mechanism 16 includes a first clamping wheel 19 and a first driving member for driving the first clamping wheel 19 to rotate; the second drill bit fixing assembly includes a first clamping seat 21 movably engaged with the first fixing assembly 1, a second clamping wheel 20 rotatably engaged with the first clamping seat 21, and a second driving member 22 for driving the first clamping seat 21 to move; the second driving member 22 is adapted to drive the second clamping wheel 20 closer to or away from the first clamping wheel 19; the third drill bit fixing assembly includes a second clamping seat 17 movably engaged with the first fixing assembly 1, and a third driving member for driving the second clamping seat 17; the second clamping seat 17 is provided with a second support portion 18 for abutting against the shank; a fixing space for accommodating the shank is formed between the first clamping wheel 19, the second clamping wheel 20, and the second support portion 18.

[0050] Specifically, by setting the first clamping wheel 19, the second clamping wheel 20, and the second clamping seat 17, it can not only stably clamp the shank to prevent deformation or shaking of the shank, but also drive the drill bit to rotate, so that the drill bit can be ground evenly at all angles.

Various modifications and variations can be made to this utility model by those skilled in the art.
