Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drill bit grabbing mechanism, and particularly relates to a drill bit whole-box grabbing mechanism. BACKGROUND

[0002] Drill bits have different types, such as drill bits with circular arc, polygon, circle and other angles. After use, the drill bits are generally subjected to grinding, cleaning, sorting and other operations. In order to better place or grab the drill bits, a sleeve ring (as shown in FIG. 1) is generally sleeved on the drill bit body, so that the drill bits can be easily grabbed. Figure 6

[0003] In the process of sorting, grinding and cleaning the drill bits, the disorderly drill bits in the needle box need to be taken out of the needle box, and after identification and cleaning, the drill bits are classified into another needle box. In this process, according to the production requirements, on the one hand, the drill bits need to be transferred to different stations for identification or cleaning, and on the other hand, the drill bits after identification or cleaning need to be replaced and placed in the needle box. Therefore, the drill bit needle box cannot be carried during the process. The commonly used drill bit grabbing manipulator generally adopts a gripper manipulator. If the gripper manipulator only grabs the drill bits without grabbing the needle box, it can only grab one or several drill bits at a time. Therefore, dozens of times of grabbing are required for a box of 50 drill bits, that is, the manipulator needs to repeat dozens of times of action to complete the identification, cleaning or box replacement and transfer of a box of 50 drill bits. This not only makes the work efficiency low, but also accelerates the wear and tear of the manipulator and reduces the service life of the manipulator. SUMMARY

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] like Figure 1As shown, a whole box of drill needle grabbing mechanism, including locking needle mechanism 1, clamping mechanism 2, push needle mechanism 3 and pressing box mechanism 4, the locking needle mechanism 1 is used to suit the whole box of drill needle needle body, the clamping mechanism 2 is arranged in the front and back of locking needle mechanism 1, for the locking needle ring of locking needle mechanism 1 is pressed, and makes locking needle mechanism 1 clamp drill needle needle body, the push needle mechanism 3 is arranged in the inside of locking needle mechanism 1, for the drill needle is pushed away from locking needle mechanism 1, the pressing box mechanism 4 is arranged in the left and right sides of locking needle mechanism 1, for drill needle grabbing lifting, the needle box is pressed tightly, so that the drill needle is pushed away from the drill needle needle box.

[0032] It should be noted that: in the embodiment, the clamping mechanism 2 is provided with two groups, which are symmetrically installed on the front and back of the locking needle mechanism 1, for simultaneously applying pressure to the locking needle ring inside the locking needle mechanism 1, so that the locking needle ring inside the locking needle mechanism 1 can be balanced, and then the whole box of drill needle can be clamped by the locking needle ring inside the locking needle mechanism 1; the push needle mechanism 3 is provided with one group, which is installed inside the locking needle mechanism 1, for pushing the drill needle away from the locking needle mechanism 1 to achieve the purpose of releasing the needle; the pressing box mechanism 4 is provided with two groups, which are respectively installed on the left and right sides of the locking needle mechanism 1, and the height of the two groups of pressing box mechanism 4 is set according to the height difference of the two sides of the needle box, so that the two groups of pressing box mechanism 4 can press the needle box from both sides to avoid the needle box being lifted after the locking needle mechanism 1 clamps the drill needle.

[0033] As shown in Figure 1 and Figure 2 The locking needle mechanism 1 includes locking needle driving device 101, locking needle box 102 and needle box rack 103, the locking needle box 102 is provided with a plurality of penetrating locking needle holes 104, the number of locking needle holes 104 is same with the number of drill needle holes in the needle box, a plurality of elastic locking needle rings 105 are arranged in the locking needle hole 104, the locking needle ring 105 can be sleeved on the drill needle needle body, the locking needle ring 105 is made of soft elastic material, the inner diameter of the locking needle ring 105 is equal to the diameter of the needle body, the lower end of the needle box rack 103 is fixedly connected with the two sides of the locking needle box 102, and the upper end of the needle box rack 103 is fixed on the output end of the locking needle driving device 101.

[0034] It should be noted that: in this embodiment, the lock pin driving device 101 adopts a lock pin cylinder, and the lock pin holes 104 are provided with 50 according to the number of drill pin holes in the needle box, so that the 50 lock pin holes 104 can correspondingly clamp the whole box of drill pins; when installing, the lock pin cylinder is fixed on the moving manipulator of the corresponding equipment and is driven to move by the moving manipulator; when it is needed to clamp the whole box of drill pins, the present application is driven by the moving manipulator to move above the whole box of drill pins, the lock pin cylinder drives the lock pin box 102 to move downward through the needle box frame 103, so that the drill pin body is inserted into the lock pin hole 104 of the lock pin box 102, and then the clamping mechanism 2 is pressed downward to apply pressure to the lock pin ring 105, so that the lock pin ring 105 is deformed, and because the inner diameter of the ring hole 107 of the lock pin hole 104 is unchanged, the lock pin ring 105 is reduced in inner diameter when being extruded and deformed, thereby achieving the purpose of clamping the drill pin; the present application can clamp the whole box of drill pins at one time by deforming the lock pin ring 105 to clamp the drill pin body, so that the transfer of the whole box of drill pins can greatly reduce the reciprocating action of the manipulator, greatly improve the work efficiency, effectively reduce the labor loss of the manipulator, and prolong the service life of the manipulator. In this embodiment, the lock pin ring 105 is made of soft rubber material with good elasticity, which effectively ensures that the lock pin ring 105 can restore to its original state after being extruded, so that the lock pin ring 105 can achieve the effect of continuous use, the inner diameter of the lock pin ring 105 is greater than or equal to the diameter of the pin body, and the difference between the two diameters is 0-1mm, preferably 0-0.6mm, so that when the lock pin ring 105 is sleeved on the pin body, the lock pin ring 105 can be accurately sleeved on the pin body, and when the lock pin ring 105 is extruded and deformed, the lock pin ring 105 deforms towards the pin body and extrudes the pin body, thereby increasing the clamping force of the lock pin ring 105 on the pin body, effectively ensuring that the lock pin ring 105 can clamp the pin body and can lift the drill pin, achieving the purpose of clamping and transferring the drill pin, and the soft rubber material of the lock pin ring 105 can also protect the drill pin during clamping, avoiding the identification code of the drill pin body from being worn out and unable to be correctly identified. In this embodiment, the present application breaks through the traditional clamping jaw clamping drill pin thinking, and extrudes the drill pin by using the soft rubber ring when it is extruded and deformed, thereby realizing a new thinking of tightly grasping the drill pin, so that the extrusion force of the lock pin ring 105 on the drill pin when it is deformed achieves the unexpected effect of clamping the drill pin.

[0035] As Figure 2 And Figure 4As shown, the locking pin hole 104 on the locking pin box 102 includes a ring hole 107, a pin sleeve hole 108, and a guide pin hole 106 that are connected vertically.

The diameter of the small end of the guide pin hole 106 is equal to the diameter of the pin sleeve hole 108. The pin sleeve hole 108 forms a clearance fit with the drill bit body, and the ring hole 107 forms a transition fit with the outer diameter of the locking pin ring 105.

[0036] It should be noted that in this embodiment, two stacked locking pin rings 105 are provided inside the ring hole 107. The inner diameter of the ring hole 107 is greater than or equal to the outer diameter of the locking pin ring 105, allowing the locking pin ring 105 to be inserted into the ring hole 107. The difference between the inner diameter of the ring hole 107 and the outer diameter of the locking pin ring 105 is controlled within the range of 0-2mm, preferably 0.5-1.5mm. Furthermore, the deformation of the locking pin ring 105 after being compressed is greater than the sum of the difference between the inner diameter of the ring hole 107 and the outer diameter of the locking pin ring 105 and the difference between the diameter of the locking pin ring 105 and the diameter of the needle body. This effectively ensures that after the locking pin ring 105 is compressed and deformed, it can use its deformation to compress the needle body, thereby achieving... The purpose is to clamp the needle body; the fit tolerance between the inner diameter of the needle hole 108 and the outer diameter of the needle body is 0-1mm, preferably 0.1-0.6mm, which can ensure that the drill needle body can be accurately inserted into the ring hole 107 through the needle hole 108; the guide hole 106 is set with an outer larger and inner smaller port, and the diameter of the larger port of the guide hole 106 is 1-5mm larger than the diameter of the smaller port, preferably 1.5-3.5mm. In this way, the flared guide hole 106 makes the larger port face outward, which can guide the insertion of the drill needle and effectively ensure that the drill needle can enter from the smaller port and be accurately inserted into the ring hole 107 through the needle hole 108.
