Description

Technical Field

[0001] The utility model belongs to the technical field of roller drill bit protection tools, in particular to a roller drill bit box. Background Art

[0002] In the field of machining and manufacturing, roller drill bits are widely used in drilling, milling and cutting processes. The roller drill bit protection box can provide a safe storage and protection environment to prevent the drill bit from being damaged. It can protect the drill bit from moisture, dust, pollution and other external factors, extending the service life of the drill bit.

[0003] Existing roller drill bit protection boxes usually rigidly restrict the shaking of the roller drill bit in the box by fixing the position, thereby improving the stability of the drill bit fixation, but this method is not suitable for roller drill bits of different sizes. When encountering a larger drill bit, the user needs to replace another drill bit box to continue working, which not only increases the tediousness of the work, but also may cause work interruption and waste of time; even a smaller roller drill bit is prone to shaking inside the box, affecting the use effect of the box. Utility Model Content

[0004] The utility model aims to provide a roller drill bit box, which solves the problem that the existing roller drill bit box cannot be used for roller drill bits of different sizes.

[0005] The technical scheme adopted by the utility model is: a roller drill bit box, comprising a box body and a box cover, the bottom of the box body is connected to clamping plates on both sides that slide with the inner wall of the box body through a damper arranged longitudinally, one end of the clamping plate is provided with a transverse sliding groove, a pair of transverse sliding blocks that extend upward and move relatively are slidably matched in the transverse sliding groove, one side of the two transverse sliding blocks that are close to each other is connected to a rubber clamping plate located above the clamping plate through a transverse spring, and the top of the box cover is connected to a rubber pad through a longitudinal spring.

[0006] The utility model is also characterized in that:

[0007] There are two double-ended screws with positive and negative threads rotatably connected in the horizontal sliding groove, and their two ends pass through the two horizontal sliding blocks and are threadedly connected thereto. A long movable groove is longitudinally opened on the side wall of the box body corresponding to one end of the double-ended screw with positive and negative threads. One end of the double-ended screw with positive and negative threads extends outward through the movable groove to the outside of the box body and is coaxially connected to a crank.

[0008] A longitudinal sliding block is fixed on each of the two sides of the clamping plate, and a longitudinal sliding groove cooperating with each longitudinal sliding block is longitudinally provided on the inner wall of the box body corresponding to each longitudinal sliding block.

[0009] The damper adopts a spring damper.

[0010] One side of the top of the box body is rotatably connected to the box cover through a hinge.

[0011] The two ends of the outer wall of the box body are rotatably connected with handles.

[0012] The beneficial effects of the utility model are as follows: the roller drill bit box of the utility model fixes the roller drill bit by two relatively movable rubber clamping plates on the clamping plate; after the roller drill bit is put in and the box cover is closed, the clamping plate that can slide up and down cooperates with the rubber pad above and the damper below to flexibly clamp the roller drill bit in the box body, and can be suitable for roller drill bits of different sizes; even if the roller drill bit is subjected to vibration or impact, since there is no gap between the roller drill bit and the surrounding areas, the drill bit can be prevented from shaking or sliding.

DETAILED DESCRIPTION

[0018] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0019] Example 1

[0020] The utility model provides a roller drill bit box, such as Figures 1 to 4As shown, it includes a box body 1, one side of the top of the box body 1 is rotatably connected to the box cover 2 through a hinge 16, and the bottom of the box body 1 is connected to a clamping plate 4 that slides with the inner wall of the box body 1 on both sides through a spring damper 3 arranged in the longitudinal direction. A longitudinal slider 14 is fixed on each side of the clamping plate 4, and a longitudinal slide groove 15 that matches with each longitudinal slider 14 is opened in the longitudinal direction on the inner wall of the box body 1. A transverse slide groove 5 is opened at one end of the clamping plate 4, and a pair of transverse sliders 6 that extend upward and move relatively are slidably matched in the transverse slide groove 5. A positive and negative double-head screw rod 11 with two ends respectively passing through the two transverse sliders 6 and threadedly connected thereto is rotatably connected in the transverse slide groove 5, and a long strip-shaped moving groove 12 is opened in the longitudinal direction on one end of the positive and negative double-head screw rod 11 corresponding to the side wall of the box body 1, and one end of the positive and negative double-head screw rod 11 passes outward through the moving groove 12 and extends to the outside of the box body 1 and is coaxially connected with a crank 13. The side where the two transverse sliders 6 are close to each other is connected to a rubber clamping plate 8 located above the clamping plate 4 through a transverse spring 7, and the top of the box cover 2 is connected to a rubber pad 10 through a longitudinal spring 9.

[0021] Example 2

[0022] The utility model provides a roller drill box. When in use, the roller drill is placed on a clamping plate 4 so that the drill neck is located between two rubber clamping plates 8. The crank 13 is rotated to drive the positive and negative double-ended screw 11 to rotate. When the positive and negative double-ended screw 11 rotates, the two transverse sliders 6 are driven to slide toward each other along the transverse sliding groove 5 through the transmission action of the screw nut. After the transverse spring 7 is compressed, the two rubber clamping plates 8 clamp the drill neck. Then, the box cover 2 is rotated and closed through the hinge 16. After closing, the longitudinal spring 9 is compressed to make the rubber pad 10 press against the upper part of the roller drill, and at the same time, the roller drill and the clamping plate 4 are pressed down to compress the damper 3. In this process, the clamping plate 4 slides downward in the longitudinal sliding groove 15 through the longitudinal slider 14, and the positive and negative double-ended screw 11 and the crank 13 move downward in the moving groove 12 with the clamping plate 4. When the box body 1 is subjected to vibration or impact, the lateral displacement of the roller drill bit is limited by the two rubber clamps 8, and the longitudinal displacement is limited by the rubber pad 10 and the damper 3, which can eliminate the gap between the roller drill bit and the surrounding clamping bodies, thereby fully absorbing the impact force of the box body 1 without generating relative shaking, and the lateral clamping distance is adjusted by the two lateral sliders 6 in combination with the lateral spring 7, and the longitudinal clamping distance is adjusted by the longitudinal spring 9 and the damper 3, so that roller drill bits of different sizes can be applied.

[0023] In the above manner, the roller drill bit box of the utility model fixes the roller drill bit by two relatively movable rubber clamping plates 8 on the clamping plate. After the roller drill bit is placed in and the box cover 2 is closed, the clamping plate 4 that can slide up and down cooperates with the rubber pad 10 above and the damper 3 below to flexibly clamp the roller drill bit in the box body 1, which can be suitable for roller drill bits of different sizes. Even if it is subjected to vibration or impact, since there is no gap between the roller drill bit and the surrounding area, it can prevent the drill bit from shaking or sliding.
