Description

Technical Field

[0001] The utility model relates to the technical field of drilling rigs, in particular to a transmission tensioning mechanism for a drilling rig. Background Art

[0002] For hardware processing drilling rigs, when two or more drill bits are required to process the same position one after another, two or more independently installed power heads are generally used to control the work of the drill bits. There are two main control methods: 1. The power head and the drill bit are fixed, and when the workpiece is transferred to different workstations, each drill bit processes synchronously; 2. The workpiece is relatively fixed and each drill bit moves and processes in turn. The first solution requires additional control devices to be configured on the workpiece fixing fixture to control the movement of the workpiece, resulting in the entire drilling rig taking up more space, which is especially not suitable for use in small and medium-sized workshops. Therefore, the second solution, that is, the solution to control the movement of the drill bit, is more widely used.

[0003] If the power head moves with the drill bit, it means that more parts need to be pulled and moved, which not only takes up space, but also makes it difficult to ensure the movement accuracy. If the power head is fixed when the drill bit is moved, a transmission device is needed to solve the technical problem of how to ensure that the transmission accuracy between the power head and the drill bit is not affected when the power head is stationary and the drill bit is moving.

[0031] Further, see Figure 2 The transmission tensioning mechanism of the drilling machine of the utility model comprises a machine base 100, on which a movable frame 300 is arranged, and the movable frame 300 moves along the direction of the linear trajectory of the movable frame movement, and the direction of the linear trajectory of the movable frame movement is taken as the first direction. A drilling device 400 is arranged on the movable frame 300, and the drilling device 400 has a tool driving wheel 410. A power device 200 is arranged on the machine base 100, and the power device 200 has an output shaft 210 for controlling the drilling device 400, and then driving the drilling tool to rotate to complete the drilling process. The drilling device 400 can adjust its position along the first direction, and when the drilling device 400 adjusts its position, it does not affect the control of the drilling device 400 by the power device 200.

[0032] Furthermore, the drilling rig transmission tensioning mechanism of the utility model also includes a transmission belt 500, which is connected to the output shaft 210 of the power device 200 and the tool driving wheel 410 of the drilling rig device 400, so as to realize the transmission control of the drilling rig device 400 by the power device 200.

[0033] Furthermore, the transmission tensioning mechanism of the drilling rig of the present invention further includes a limited range guide wheel set 510, which is arranged on the machine base 100 and connected to the transmission belt 500, and is located between the power device 200 and the drilling rig device 400. The limited range guide wheel set 510 includes a first limited range guide wheel 511 and a second limited range guide wheel 512, and the first limited range guide wheel 511 and the second limited range guide wheel 512 are distributed along the first direction.

[0034] Furthermore, the transmission tensioning mechanism of the drilling rig of the utility model also includes a transition wheel group 520, which is arranged on the movable frame 300 and connected to the transmission belt 500, and the transition wheel group 520 is located between the limited range guide wheel group 510 and the drilling rig device 400. The transition wheel group 520 includes a first transition wheel 521 and a second transition wheel 522, and the first transition wheel 521 and the second transition wheel 522 are distributed along the first direction.

[0036] During specific operation, the drilling device 400 of the drilling rig transmission tensioning mechanism of the utility model can be moved along the movable frame 300 to adjust the position as needed, thereby adjusting the drilling position. During the above position adjustment process, the power device 200 driving the tool of the drilling device 400 does not need to move on the machine base 100, and the driving belt 500 is used to keep the tool of the drilling device 400 working.

In this way, the limited range guide wheel set 510 and the transition wheel set 520 cooperate to form a transition effect, ensuring that the transmission accuracy of the transmission belt 500 is not affected when the movable frame 300 moves, thereby ensuring that the operation of the drilling rig device 400 is not affected by the movement of the movable frame 300.

[0038] It is conceivable that the number of drilling devices 400 on the movable frame 300 can be designed according to needs, for example Figure 1 , Figure 2 The number of the drilling devices 400 in the embodiment is two.

The transition wheel assembly 520 is arranged on the connecting frame extension plate 312, and the connecting frame extension plate 312 points to the limited range guide wheel assembly 510, which is equivalent to extending the transition wheel assembly 520 toward the position of the limited range guide wheel assembly 510, so as to facilitate shortening the distance between the limited range guide wheel assembly 510 and the transition wheel assembly 520.

[0055] Some embodiments, see Figure 1 , Figure 2 The feeding direction of the drilling device as the second direction is the front-to-back direction, that is, the drilling device 400 controls the front-to-back movement through the feeding control device 130 to feed the tool.
