Description

Technical Field

[0001] The utility model belongs to the technical field of drilling devices, and particularly relates to a rotatable drill die locking seat. Background Art

[0002] The process method of using a drill bit to process holes in solid materials is called drilling. Drilling is one of the basic methods of hole processing. Drilling is usually carried out on a drilling machine or a lathe, and can also be carried out on a boring machine or a milling machine. When drilling, usually the drill rod remains stationary, and the tool makes a feeding motion, and the drilling position is adjusted by rotating the workpiece to be machined.

[0003] In the actual production process, generally, the drilling positions are marked on the workpiece to be machined first, and workers rotate the workpiece manually according to the marked positions to adjust the drilling positions. In this way, it usually leads to insufficient accuracy of drilling processing and cannot meet the normal use requirements. In addition, during the manual rotation process, it is inevitable to make fine adjustments to the rotation angle, thus wasting time and being unfavorable to the improvement of work efficiency. Summary of the Invention

[0004] In view of this, the purpose of the utility model is to provide a rotatable drill die locking seat to solve the technical problems of insufficient accuracy and low processing efficiency caused by manually rotating the workpiece in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rotatable drill die locking seat includes a drilling indexing plate, an indexing turntable, and a drilling die seat arranged in sequence from bottom to top. The drilling indexing plate is fixedly connected to the workbench below it, the indexing turntable is fixedly connected to the drilling die seat, the indexing turntable is rotationally connected to the drilling indexing plate, a drilling locking seat mechanism is arranged outside the drilling indexing plate, the drilling locking mechanism includes a locking seat fixedly connected to the indexing turntable, the locking seat includes a main body with a cavity formed inside, a locking pin is slidably connected in the cavity, the outer end of the locking pin is elastically connected to the locking seat, two limiting grooves are arranged on the side surface of the drilling indexing plate, the inner end of the locking pin can extend into the limiting grooves, a push rod is rotationally connected to the main body, a push block is arranged on the push rod, the push block extends into a through hole on the top surface of the locking pin, the drilling locking seat mechanism further includes a limiting post arranged outside the limiting grooves, and the limiting post limits the rotation angle of the locking seat;

[0007] Further, the main body is in a cuboid shape, the main body is arranged opposite to the drilling indexing plate along its length direction, and the inner end surface of the main body opposite to the drilling indexing plate is in an arc shape so that the two are completely attached, so as to form a smooth contact between the main body and the drilling indexing plate;

[0008] Further, a first opening communicating with the cavity is formed on the inner end surface of the main body, and the cross-sectional dimension of the first opening is consistent with the longitudinal cross-sectional dimension of the cavity. A second opening communicating with the cavity is formed on the top surface of the main body;

[0009] Further, bumps are welded on both sides of the second opening along the width direction of the main body. A rotating shaft is fixedly connected between the bumps along the width direction of the main body. A push rod is rotatably connected to the rotating shaft. The push rod includes a handle extending outside the locking seat and a connecting ring fixedly connected to the end of the handle. The connecting ring is adapted to the rotating shaft;

[0010] Further, the through hole on the top surface of the locking pin is opposite to the second opening;

[0011] Further, the inner end of the locking pin contracts along the width direction to form a trapezoidal bump. The limiting groove gradually contracts from outside to inside along the diameter direction of the drilling indexing plate so that the limiting groove matches the trapezoidal end of the locking pin. The inner end of the locking pin can extend into the limiting groove;

[0012] Further, a third opening communicating with the cavity is formed on the bottom surface of the main body. The third opening is opposite to the through hole, reserving sufficient space for the rotation of the push block.

[0014] Compared with the prior art, by setting the locking seat mechanism, pushing the handle to apply a force can complete the rotation and fixation of the indexing turntable and the drilling die base. On the one hand, the limiting column precisely controls the rotation angle of the locking seat. When the locking seat abuts against the limiting column, the locking pin is exactly opposite to the limiting groove, and the guiding hole is also exactly opposite to the cutting tool above it, thereby realizing the precise rotation of the workpiece. And the whole process is simple to operate, without the need for multiple adjustments of the rotation angle, greatly improving the work efficiency and drilling accuracy; on the other hand, the lever function of the handle can greatly save the physical energy of workers and reduce their labor intensity.

Detailed implementation mode

[0024] The first embodiment is specifically as Figures 1-6 shown.

[0025] As Figure 1 shown, a rotatable drilling die locking seat includes a drilling indexing plate 2, an indexing turntable 3, and a drilling die base 4 arranged in sequence from bottom to top. The three are in a horizontal state and in contact with each other. The disc-shaped drilling indexing plate 2 is threadedly fixed to the workbench 1 below it. The indexing turntable 3 is threadedly connected and fixed to the drilling die base 4 to form an integral body. A rotating shaft is provided at the inner axis of the indexing turntable 3 and the drilling indexing plate 2, and the rotation connection between the two is realized through the rotating shaft.

[0026] Three positioning posts 41 are threadedly connected to the top surface of the drilling die base 4 at equal intervals along the circumferential direction. Through the triangular positioning structure formed by the three positioning posts, the workpiece to be processed can be effectively fixed with a smaller number of positioning posts 42, preventing displacement during the processing. Two groups of guide holes 42 are also opened on the top surface of the drilling die base 4. Each group of guide holes 42 includes three guide holes 42 evenly distributed along the circumferential direction, and the above three guide holes are arranged at intervals with the positioning posts 41.

[0027] In the actual production process, a tool corresponding to a group of guide holes 42 is fixed above the drilling die base 4. The workpiece to be processed is drilled once through the downward feeding movement of the tool. When the first drilling is completed, the drilling die base 4 is manually rotated to make the other group of guide holes 42 on the drilling die base 4 correspond to the tool, and then the second drilling is carried out. The method of manually adjusting the guide holes not only has low efficiency, but also it is very difficult to accurately grasp the rotation amplitude, thus affecting the drilling accuracy.

[0028] Based on this, a drilling locking seat mechanism 5 is provided on the outer side of the drilling indexing plate 2. The drilling locking mechanism 5 includes a locking seat 51 fixedly connected to the indexing turntable 3. The locking seat 51 includes a cuboid-shaped main body 511. The main body 511 faces the drilling indexing plate 2 along its length direction, and the inner end face of the main body 511 opposite to the drilling indexing plate 2 is an arc surface so that the two are completely fitted, thereby forming a smooth contact between the main body 511 and the drilling indexing plate 2. A cuboid-shaped cavity 512 is formed inside the main body 511. A first opening 513 communicating with the cavity 512 is opened on the inner end face of the main body 511. The cross-sectional dimension of the first opening 513 is the same as the longitudinal cross-sectional dimension of the cavity 512. A second opening 514 communicating with the cavity 512 is opened on the top surface of the main body 511. Vertical convex blocks 515 are welded on both sides of the second opening 514 along the width direction of the main body 511. In this embodiment, there is a gap between the convex blocks 515 and the inner end face of the main body 511, and the inner end face of the convex blocks 515 is in contact with the side surface of the indexing turntable 3. The main body 511 and the indexing turntable 3 are fixed by threaded connection.

[0029] A locking pin 52 is slidably connected in the cavity 512. The locking pin 52 is integrally cuboid-shaped, and its inner end part shrinks along the width direction to form a trapezoidal convex block. A through hole 521 opposite to the second opening 514 is opened on the top surface of the locking pin 52. A rotating shaft 516 is welded between the convex blocks 515 along the width direction of the main body 511. A push rod 53 is rotatably connected to the rotating shaft 516. The push rod 53 includes a handle 531 extending outside the locking seat 51 and a connecting ring 532 welded to the end of the handle 531. The connecting ring 532 is adapted to the rotating shaft 516, thereby realizing the rotational connection between the main body 511 and the push rod 53. A push block 533 is integrally formed on the side of the connecting ring 532 away from the handle 531. The push block 533 extends into the through hole 521. There is a gap between the outer end of the locking pin 52 and the cavity 512, and a spring 54 is arranged in the gap, thereby realizing the elastic connection between the locking pin 52 and the locking seat 51.

[0030] Two limiting grooves 21 are opened on the side surface of the drilling indexing plate 2. The limiting grooves 21 gradually contract from the outside to the inside along the diameter direction of the drilling indexing plate 2 so that the limiting grooves 21 match the trapezoidal end of the locking pin 52, and the inner end of the locking pin 52 can extend into the limiting grooves 21. The drilling locking seat mechanism 5 further includes a limiting post 55 arranged outside the limiting grooves 21. The limiting post 55 is threadedly connected to the workbench 1, and the rotation angle of the locking seat 51 is limited by the limiting post 55.

[0031] In use, first, the trapezoidal end of the locking pin 52 is located in one side limiting groove 21, thereby fixing the indexing turntable 3 and the drilling die base 4. At this time, the cutting tool is aligned with a set of guiding holes 42, and the workpiece is drilled once by feeding the cutting tool. Then, when the first drilling is completed, hold the handle 531 and rotate the push rod 53 clockwise along the rotating shaft 516. The push block 533 rotates synchronously and pushes the locking pin 52 to slide outwards along the first opening 513. The spring 54 is compressed, and the trapezoidal end of the locking pin 52 is separated from the limiting groove 21, releasing the rotation restriction of the indexing turntable 3 and the drilling die base 4. Then, apply an external force in the horizontal circumferential direction to the handle 531, so that the locking seat 51, the indexing turntable 3 and the drilling die base 4 rotate synchronously until the locking seat 51 abuts against the limiting post 55, so that the cutting tool is aligned with another set of guiding holes 42. At this time, release the handle 531, and the locking pin 52 slides inwards under the elastic return action of the spring 54, and its trapezoidal inner end enters the limiting groove 21 on the other side, realizing the re-fixation of the indexing turntable 3 and the drilling die base 4. Finally, feed the cutting tool to drill the workpiece for the second time.

[0032] In order to prevent the push block 533 from contacting the main body 511 below the cavity 512 during rotation, thereby affecting the normal rotation of the push block 533, a third opening 517 communicating with the cavity 512 is formed in the bottom surface of the main body 511. The third opening 517 is opposite to the through hole 521, thereby reserving sufficient space for the rotation of the push block 533.

[0033] By setting the locking seat mechanism 5, applying a force to the handle 531 can complete the rotation and fixation of the indexing turntable 3 and the drilling die base 4. On the one hand, the limiting post 55 precisely controls the rotation angle of the locking seat 51. When the locking seat 51 abuts against the limiting post 55, the locking pin 52 is exactly opposite to the limiting groove 21, and the guiding hole 42 is also exactly opposite to the cutting tool above it, thereby realizing the precise rotation of the workpiece. And the whole process is simple to operate, without multiple adjustments of the rotation angle, greatly improving the work efficiency and drilling accuracy; on the other hand, the lever function of the handle 531 can greatly save the physical energy of workers and reduce their labor intensity.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
