Description

Technical Field

[0001] The present invention relates to the field of drill bit processing equipment, in particular to a drill bit clamping mechanism and a drill bit grinding device. Background Art

[0002] Before placing electronic components on a circuit board, multiple holes must be drilled at regular intervals to accommodate these components. Currently, micro drills are commonly used to perforate circuit boards. However, after a period of use, the micro drill's blade can become blunt or even break, causing inconvenience and errors. Therefore, the micro drill's blade must be reground to ensure quality.

[0003] During the grinding process of the micro drill, a drill clamping mechanism is required to clamp the micro drill to prevent the micro drill from breaking or deflecting during the grinding process. The current drill clamping mechanism includes a first clamping jaw and a second clamping jaw, both of which are provided with a clamping V-groove. The two clamping V-grooves cooperate to clamp the micro drill, and the micro drill is arranged between the two clamping V-grooves. In the prior art, under the drive of a driving device, the first clamping jaw and the second clamping jaw rotate toward each other to achieve closeness, completing the clamping of the micro drill. After the grinding of the micro drill is completed, under the drive of the driving device, the first clamping jaw and the second clamping jaw simultaneously rotate away from each other to loosen the clamping of the micro drill. During the loosening process, the first clamping jaw and the second clamping jaw simultaneously rub or collide with the outer peripheral surface of the micro drill, and the forces of the first clamping jaw and the second clamping jaw simultaneously overlap and act on the drill, which can easily cause the micro drill to deform and damage.

[0004] In view of this, it is necessary to design a drill bit clamping mechanism and a drill bit grinding device to reduce the possibility of damage to the drill bit during the loosening process. Summary of the Invention

[0005] The object of the present invention is to provide a drill bit grinding device to reduce the possibility of the drill bit being damaged during the process of releasing the drill bit from a drill bit clamping mechanism.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] A drill bit clamping mechanism comprises a base on which a first clamping member and a second clamping member arranged opposite to each other are rotatably mounted, and an elastic reset assembly is further mounted on the base for driving the first clamping member and the second clamping member to rotate toward each other to clamp the drill bit;

[0008] The base is provided with a driving assembly, which includes a driving member and an opening member connected to the driving member; the driving member is used to drive the opening member to move along a preset first direction to open the second clamping member and the first clamping member in sequence.

[0009] Optionally, a first opening inclined surface is provided on a side surface of the first clamping member close to the second clamping member, and a second opening inclined surface is provided on a side surface of the second clamping member close to the first clamping member;

[0010] When the spreading member is driven to move along the first direction, the spreading member first contacts the second spreading inclined surface and then contacts the first spreading inclined surface.

[0011] Optionally, the elastic reset assembly includes a first elastic reset assembly connected to the first clamping member, and a second elastic reset assembly connected to the second clamping member;

[0012] The first elastic reset assembly is used to drive the first clamping member to rotate in a direction close to the second clamping member, and the second elastic reset assembly is used to drive the second clamping member to rotate in a direction close to the first clamping member.

[0013] Optionally, the first elastic reset assembly includes a positioning column and a first elastic member, the positioning column is installed in the base; one end of the first elastic member is connected to the positioning column, and the other end abuts against the first clamping member.

[0014] Optionally, the first elastic reset assembly further includes a limiting member, and the limiting member is installed on the base;

[0015] The first clamping member includes a clamping portion arranged opposite to the second clamping member, a rotating portion rotatably connected to the base, and an adjusting portion adapted to the limiting member, wherein two ends of the rotating portion are respectively connected to the clamping portion and the adjusting portion;

[0016] When the spreading member is released from contact with the first spreading inclined surface, the limiting member abuts against the adjusting portion under the action of the elastic force of the first elastic member.

[0017] Optionally, the limiting member includes an eccentric shaft segment and a rotating shaft segment rotatably connected to the base; when the support member is disengaged from the first support inclined surface, the eccentric shaft segment abuts against the adjustment portion under the elastic force of the first elastic member.

[0018] Optionally, the second elastic reset assembly includes a second fixed column, a second connecting column and a second elastic member, the second fixed column is fixedly connected to the base, the second connecting column is fixedly connected to the second clamping member, one end of the second elastic member is connected to the second fixed column, and the other end is connected to the second connecting column.

[0019] Optionally, a second limiting groove is formed on the base, one end of the second connecting column is connected to the second elastic member, and the other end passes through the second limiting groove and is fixedly connected to the second clamping member;

[0020] When the spreading member is released from contact with the second spreading inclined surface, the second connecting column abuts against the side groove wall of the second limiting groove under the elastic force of the second elastic member.

[0021] Optionally, a first slide groove and a second slide groove are provided in the base, the first slide groove and the second slide groove are communicated with each other, the first slide groove extends along the first direction, and the second slide groove extends along the second direction;

[0022] The driving assembly further includes a first slider slidably disposed in the first sliding groove and a second slider slidably disposed in the second sliding groove; one end of the first slider is connected to the expansion member, a first end of the second slider is connected to the driving member, and a second end of the second slider abuts against the other end of the first slider;

[0023] When the driving member drives the second slider to move along the second direction, the second slider pushes the first slider and the expansion member to move along the first direction.

[0024] A drill bit grinding device comprises the drill bit clamping mechanism as described in any one of the above items.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] When the driver drives the expansion member to move in a preset first direction, the expansion member first contacts the second expansion slope, thereby pushing the second clamping member to rotate away from the first clamping member. At this time, the first clamping member remains in place, providing support for the drill bit and effectively preventing the drill bit from being hit by the second clamping member and causing excessive deformation. The expansion member then moves in the first direction, pushing the first clamping member to rotate away from the second clamping jaw, thereby loosening the drill bit and allowing the drill bit to proceed to the next step. By staggering the opening time of the first and second clamping members, the forces of the first and second clamping members cannot act on the drill bit simultaneously, effectively reducing the force acting on the drill bit during the release process of the drill clamping mechanism, thereby reducing the possibility of deformation and damage to the drill bit.

DETAILED DESCRIPTION

[0037] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0040] Example 1

[0041] See also Figures 1 to 7 The drill bit clamping mechanism includes a base 1 on which a first clamping member 2 and a second clamping member 3 are rotatably mounted relative to each other. The base 1 also includes an elastic reset assembly for driving the first clamping member 2 and the second clamping member 3 to rotate toward each other to clamp the drill bit. The base 1 serves as a support.

[0042] A driving assembly 4 is provided on the base 1, and the driving assembly 4 includes a driving member 42 and a spreading member 41 connected to the driving member 42; the driving member 42 is used to drive the spreading member 41 to move along a preset first direction to spread the second clamping member 3 and the first clamping member 2 in sequence.

[0043] Specifically, after the drill needle is ground, the clamping claw on the manipulator clamps one end of the drill needle, and the driving member 42 drives the stretching member 41 to move along the preset first direction. During the movement of the stretching member 41 along the first direction, the second clamping member 3 is first stretched open, so that the second clamping member 3 rotates in the direction away from the first clamping member 2. At this time, the first clamping member 2 remains in place, forming a support for the drill needle, which can effectively prevent the drill needle from being touched or rubbed by the second clamping member 3 and causing excessive deformation; then, the stretching member 41 continues to move along the first direction, stretching the first clamping member 2, so that the first clamping member 2 moves in the direction away from the second clamping member 3, thereby releasing the drill needle, and the manipulator can transfer the drill needle to the next processing step.

[0044] It should be noted that, in this embodiment, by staggering the opening time of the first clamping member 2 and the second clamping member 3, it can effectively avoid the drill bit being simultaneously subjected to the outward tension of the first clamping member 2 and the second clamping member 3, thereby causing the drill bit to deform, which is beneficial to reducing the probability of damage to the drill bit and ensuring the processing quality of the drill bit.

[0045] It should also be noted that both the first clamping member 2 and the second clamping member 3 are provided with clamping grooves for clamping the drill bit. Preferably, both the first clamping member 2 and the second clamping member 3 are provided with V-shaped clamping grooves. When clamping the drill bit, the notches of the V-shaped clamping groove on the first clamping member 2 and the V-shaped clamping groove on the second clamping member 3 are arranged opposite each other. The provision of the V-shaped clamping groove helps improve the clamping precision of the drill bit.

[0046] It should also be noted that the first direction can be set according to actual needs, such as horizontal direction, vertical direction or inclined direction, as long as the expansion member 41 can expand the second clamping member 3 and the first clamping member 2 in sequence during the movement along the first direction, thereby achieving the purpose of loosening the clamping of the drill bit.

[0047] In a specific implementation, a first opening slope 201 is provided on a side surface of the first clamping member 2 close to the second clamping member 3, and a second opening slope 301 is provided on a side surface of the second clamping member 3 close to the first clamping member 2; when the opening member 41 is driven to move along the first direction, the opening member 41 first contacts the second opening slope 301 and then contacts the first opening slope 201.

[0048] In this embodiment, by providing a first opening bevel 201 and a second opening bevel 301, the driving member 42 drives the opening member 41 to move along the first direction, thereby achieving the purpose of sequentially opening the first clamping member 2 and the second clamping member 3. The opening member 41 is arranged between the first clamping member 2 and the second clamping member 3. During the movement of the opening member 41 along the first direction, it first contacts the second opening bevel 301, thereby pushing the second clamping member 3 to rotate in a direction away from the first clamping member 2. The opening member 41 then moves along the first direction and pushes the first clamping member 2 to move in a direction away from the second clamping member 3, thereby achieving the effect of staggered opening. Preferably, the preset reference plane is perpendicular to the first direction, and the angle between the first opening bevel 201 and the preset reference plane is greater than the angle between the second opening bevel 301 and the preset reference plane.

[0049] Optionally, the elastic reset assembly includes a first elastic reset assembly 5 connected to the first clamping member 2, and a second elastic reset assembly 6 connected to the second clamping member 3; the first elastic reset assembly 5 is used to drive the first clamping member 2 to rotate toward the direction close to the second clamping member 3, and the second elastic reset assembly 6 is used to drive the second clamping member 3 to rotate toward the direction close to the first clamping member 2.

[0050] Specifically, the first elastic reset component 5 elastically deforms itself, causing the first clamping member 2 to have a tendency to rotate in a direction close to the second clamping member 3; similarly, the second elastic reset component elastically deforms itself, causing the second clamping member 3 to have a tendency to rotate in a direction close to the first clamping member 2. It should be further explained that the force of the first elastic reset component 5 to restore its own elastic deformation pushes the first clamping member 2, and the force of the second elastic reset component 6 to restore its own elastic deformation pushes the second clamping member 3, thereby allowing the first clamping member 2 and the second clamping member 3 to cooperate in clamping the drill needle. It should also be explained that by replacing the first elastic reset component 5 and the second elastic reset component 6, the elastic coefficient of the first elastic reset component 5 and the elastic coefficient of the second elastic reset component 6 installed on the base 1 can be changed, thereby changing the clamping force of the clamping drill needle.

[0051] It should be further added that after the driving member 42 stops driving, the first elastic reset component 5 resets the first clamping member 2, and the second elastic reset component 6 resets the second clamping member 3, thereby clamping the drill bit at the preset clamping position.

[0052] Optionally, the first elastic reset assembly 5 includes a positioning column 51 and a first elastic member 52, and the positioning column 51 is installed in the base 1; one end of the first elastic member 52 is connected to the positioning column 51, and the other end abuts the first clamping member 2. It should be noted that the first elastic member 52 is compressed and arranged between the positioning column 51 and the first clamping member 2, and the elastic force of the first elastic member 52 enables the first clamping member 2 to cooperate with the second clamping member 3 to clamp the drill needle. In the process of the support member 41 pushing the first support slope 201, the first elastic member 52 is further compressed, so that the drill needle is released. It should be further explained that the first elastic member 52 can be a spring, an elastic column, an elastic block or other elastic components; or, the second elastic member 63 can be a metal elastic member or a non-metallic elastic member. Preferably, as Figure 2 The base 1 is provided with a mounting through hole, at least part of which is a threaded hole section. The outer periphery of the positioning column 51 is provided with an external thread that cooperates with the threaded hole section. The positioning column 51 can be rotated to adjust the position, thereby adjusting the compression degree of the first elastic member 52, and finally realizing the adjustment of the clamping force of the clamping drill bit.

[0053] Optionally, the first elastic reset assembly 5 further includes a limiter 53, which is mounted on the base 1; the first clamping member 2 includes a clamping portion 21 arranged opposite to the second clamping member 3, a rotating portion 22 rotatably connected to the base 1, and an adjusting portion 23 adapted to the limiter 53, with the two ends of the rotating portion 22 respectively connected to the clamping portion 21 and the adjusting portion 23. The adjusting portion 23 is adapted to the limiter 53, which means that the adjusting portion 23 is provided with a contact surface that can contact the limiter 53, so that the adjusting portion 23 can stably contact the limiter 53. Figure 1 When the opening member 41 breaks contact with the first opening inclined surface 201, the limiting member 53 abuts the adjusting portion 23 under the elastic force of the first elastic member 52. It should be noted that the limiting member 53 acts as a limiter for the first clamping member 2, preventing the first clamping member 2 from approaching the second clamping member 3, thereby preventing damage caused by collision between the first clamping member 2 and the second clamping member 3. In other words, during actual operation, after the adjusting portion 23 abuts the limiting member 53, the first clamping member 2 cannot rotate further toward the second clamping member 3.

[0054] Optionally, the limiting member 53 includes an eccentric shaft segment 531 and a rotating shaft segment 532 rotatably connected to the base 1; when the opening member 41 disengages from the first opening inclined surface 201, the eccentric shaft segment 531 abuts the adjustment portion 23. Specifically, in this embodiment, the position of the adjustment portion 23 can be changed by adjusting the rotation angle of the eccentric shaft segment 531, thereby causing the first clamping member 2 to rotate to adjust the position of the clamping portion 21. That is, by adjusting the rotation angle of the eccentric shaft segment 531, the clamping position of the drill bit can be adjusted so that the clamping portion 21 can be parallel to the clamping portion of the second clamping member 3, thereby better clamping the drill bit. Furthermore, a fixing member for fixing the rotating shaft segment 532 is provided on the base 1. After the eccentric shaft segment 531 rotates to the optimal adjustment position, the rotating shaft segment 532 is fixed by the fixing member, thereby achieving the fixation of the limiting member 53. Preferably, the first clamping member 2 includes a first rotating shaft rotatably connected to the base 1, the second clamping member 3 includes a second rotating shaft rotatably connected to the base 1, and the center line of the rotating shaft segment, the center line of the first rotating shaft and the center line of the second rotating shaft are parallel to each other.

[0055] Optionally, the second elastic reset assembly 6 includes a second fixed column 61, a second connecting column 62 and a second elastic member 63, the second fixed column 61 is fixedly connected to the base 1, the second connecting column 62 is fixedly connected to the second clamping member 3, one end of the second elastic member 63 is connected to the second fixed column 61, and the other end is connected to the second connecting column 62.

[0056] It should be noted that the elastic force of the second elastic member 63 causes the second clamping member 3 to rotate toward the first clamping member 2, thereby cooperating with the first clamping member 2 to clamp the drill needle. Specifically, the elastic force of the second elastic member 63 pulls the second clamping member 3 toward the first clamping member 2, with one end of the second elastic member 63 fixedly connected to the second fixing column 61 and the other end fixedly connected to the second connecting column 62. It should be noted that the second elastic member 63 is a spring, an elastic column, an elastic block, or other elastic component; alternatively, the second elastic member 63 can be a metallic or non-metallic elastic member. In this embodiment, the second elastic member 63 is a spring.

[0057] Optionally, a second limiting groove 101 is formed on the base 1 , one end of the second connecting column 62 is connected to the second elastic member 63 , and the other end passes through the second limiting groove 101 and is fixedly connected to the second clamping member 3 .

[0058] When the opening member 41 is released from contact with the second opening slope 301, the elastic force of the second elastic member 63 causes the second connecting post 62 to move closer to the first clamping member 2 until the second connecting post 62 contacts the side walls of the second limiting groove 101. At this point, the side walls of the second limiting groove 101 act as a limiter for the second clamping member 3, preventing the second clamping member 3 from rotating excessively and thus avoiding collision between the first clamping member 2 and the second clamping member 3. It should also be noted that the second limiting groove 101 also creates a gap for the second clamping member 3 to rotate away from the first clamping member 2.

[0059] It should also be noted that, when the opening member 41 contacts the second opening inclined surface 301 to open the second clamping member 3, the second clamping member 3 rotates away from the first clamping member 2. After the first clamping member 2 and the second clamping member 3 are both opened, the drill bit can enter the clamping position.

[0060] Optionally, a first slide groove 102 and a second slide groove 103 are provided in the base 1 , the first slide groove 102 and the second slide groove 103 are communicated with each other, the first slide groove 102 extends along the first direction, and the second slide groove 103 extends along the second direction.

[0061] The driving assembly 4 also includes a first slider 43 slidably set in the first sliding groove 102 and a second slider 44 slidably set in the second sliding groove 103. One end of the first slider 43 is connected to the support member 41, the first end of the second slider 44 is connected to the driving member 42, and the second end of the second slider 44 abuts against the end of the first slider 43.

[0062] In the actual process, when the driving member 42 drives the second slider 44 to move along the second direction, the second slider 44 pushes the first slider 43 and the support member 41 to move synchronously along the first direction, so that the support member 41 first contacts the second support inclined surface 301, and then contacts the first support inclined surface 201.

[0063] It should be noted that in this embodiment, the movement of the driving member 42 is transmitted through the first slider 43 and the second slider 44, which can effectively prevent the first clamping member 2 and the second clamping member 3 from being affected by the unstable driving of the driving member 42, thereby improving the driving accuracy. Figure 2The first slider 43 slides in the first chute 102 along the first direction, while the second slider 44 slides in the second chute 103 along the second direction. The maximum height of the first slider 43 is actually related to the thickness of the second slider 44. This effectively prevents the first slider 43 from rising too high and damaging the first clamp 2 and the second clamp 3. It should be noted that the thickness of the second slider 44 here refers to the height of the second slider 44 perpendicular to the extension direction of the second chute 103.

[0064] In a specific embodiment, the first direction is perpendicular to the second direction; that is, the first slide groove 102 and the second slide groove 103 are perpendicular to each other. The second end of the first slider 43 is provided with a first inclined surface, and the second end of the second slider 44 is provided with a second inclined surface, and the first inclined surface and the second inclined surface are in contact with each other. When the driving member 42 drives the second slider 44 to move along the second direction, the second inclined surface pushes the first inclined surface, thereby causing the first slider 43 to move along the first direction. In this embodiment, the inclination angles of the first inclined surface and the second inclined surface are both 45°. It should also be added that the first slide groove 102 can be tilted relative to the second slide groove 103, as long as the second slider 44 can push the first slider 43 to slide along the first direction.

[0065] Optionally, when the expansion member 41 is located at a preset initial position, one end of the expansion member 41 does not contact either the first expansion bevel 201 or the second expansion bevel 301. At this time, the gap between the expansion member 41 and the first expansion bevel 201 is larger than the gap between the expansion member 41 and the second expansion bevel 301. Therefore, when the first slider 43 slides along the first chute 102, the expansion member 41 first contacts the second expansion bevel 301 and then contacts the first expansion bevel 201. In this embodiment, a first curved surface for contacting the first expansion bevel 201 and a second curved surface for contacting the second expansion bevel 301 are provided at both ends of the expansion member 41. The expansion member 41 contacts the first expansion slope 201 through the first curved surface, thereby pushing the first clamping member 2 to rotate, and the first curved surface can effectively avoid scratching the first expansion slope 201; the expansion member 41 contacts the second expansion slope 301 through the second curved surface, thereby pushing the second clamping member 3 to rotate, and the second curved surface can effectively avoid scratching the second expansion slope 301.

[0066] It should also be noted that if Figure 6 and Figure 7As shown, the drill bit clamping structure further includes a third reset assembly, which includes a third fixing column 71, a third connecting column 72, and a third elastic member 73. The third fixing column 71 is fixedly connected to the base, the third connecting column 72 is fixedly connected to the expansion member 41, and the opposite ends of the third elastic member 73 are respectively connected to the third connecting column 72 and the third fixing column 71. Specifically, after the first clamping member 2 and the second clamping member 3 are completely opened, and the drill bit is moved to the set clamping position by the manipulator, the drive shaft of the driving member 42 is retracted. At this time, the expansion member 41 moves downward under the elastic force of the third elastic member, and the expansion member 41 returns to the preset initial position. The first clamping member 2 and the second clamping member 3 are reset and clamped.

[0067] It should also be noted that an arc-shaped groove 104 for avoiding the gripping claws of the manipulator is provided on the top of the base 1. When the first clamping member 2 and the second clamping member 3 are opened, it is more convenient to load or unload the drill.
