Description

Technical Field

[0001] The utility model relates to the technical field of drill bit processing, in particular to a manipulator for taking and placing a drill bit and a drill bit processing device. Background Art

[0002] The present invention relates to a robot which is used to remove and place drill bits, and the robot has a high requirement for the movement accuracy of the robot. However, the existing robot for taking and placing drill bits has a slide which is slidably arranged on the support seat by a sliding structure. The sliding structure includes a cylindrical guide rod arranged on the support seat and a cylindrical hole arranged in the slide seat. The cylindrical hole and the guide rod are matched with each other to slide and cooperate with each other to realize the sliding arrangement of the slide on the support seat. The clamp is installed at one end of the slide seat, and the driving mechanism is connected to one end of the slide seat. The driving mechanism drives the slide plate and the clamp to move back and forth on the support seat together, and then cooperates with the support seat to drive the clamp to rotate, thereby taking and placing the drill bit. However, the sliding structure composed of the cylindrical hole and the guide rod can easily cause the clamp to rotate and deviate during movement, thereby affecting the accuracy of clamping and placing the drill bit. Frequent adjustment and maintenance are required in the later stage, which affects work efficiency. Although there is a way to improve the sliding accuracy of the clamp by setting multiple sets of sliding structures, it makes the overall structure of the robot too complicated, which increases unnecessary costs.

[0023] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] See Figure 1-6 As shown, as an embodiment of the present invention, a manipulator for picking up and placing a drill bit is provided, comprising a rotary drive member 1, a support seat 2, a slide 3, a sliding structure, a clamping jaw 5, and a telescopic drive member 4. The support seat 2 is rotatably mounted on the rotary drive member 1, the sliding structure comprises a guide rail 7 fixedly mounted on the support seat 2 and a slider 6 fixedly mounted on the slide 3, the slider 6 slidingly cooperates with the guide rail 7 to enable the slide 3 to be slidably arranged on the support seat 2, the telescopic drive member 4 is fixedly mounted on the support seat 2 and is drive-connected to one end of the slide 3, and the clamping jaw 5 is mounted on the end of the slide 3 away from the telescopic drive member 4. The sliding structure of the present invention adopts a structure in which the slider 6 cooperates with the guide rail 7, rather than a structure in which a cylindrical guide rod cooperates with a cylindrical hole, thereby effectively preventing the slide 3 and the clamping jaw 5 from rotating and deviating during movement on the support seat 2, thereby ensuring the accuracy of clamping and placing the drill bit, avoiding frequent adjustment and maintenance of the manipulator in the later stage, improving work efficiency and stability, and only requiring one set of sliding structures, making the overall structure of the manipulator simpler and saving structural costs.

[0025] Specifically, the outer walls on both sides of the guide rail 7 are respectively concave to form a slide groove 71, and the slider 6 is provided with a U-shaped bayonet portion 61. The inner walls on both sides of the bayonet portion 61 are respectively extended to form ridges 62. The ridges 62 correspond to the slide groove 71 and slide accurately. The ridges 62 have a symmetrical structure, which includes a semi-cylinder 621 and a cylinder 622 located at the extended end of the semi-cylinder 621. The diameter of the semi-cylinder 621 is larger than the diameter of the cylinder 622, and there is an arc-shaped transition between the semi-cylinder 621 and the cylinder 622. The shapes and sizes of the ridges 62 and the slide groove 71 correspond to each other, so that the slider 6 and the guide rail 7 can be tightly fitted with each other, and are not prone to loosening and tripping. The precision is higher, and the sliding process is smoother and more stable.

[0026] In this embodiment, the clamping jaw 5 includes a clamping jaw cylinder 52 and two clamping jaw bodies 51 connected to one end of the clamping jaw cylinder 52. The clamping jaw cylinder 52 drives the clamping jaw bodies 51 to move closer to each other to clamp the drill bit. When the drill bit needs to be put down, the clamping jaw cylinder 52 drives the two clamping jaw bodies 51 to move away from each other to release the drill bit, thereby realizing the action of taking and placing the drill bit.

[0027] In this embodiment, the rotary drive component 1 is a rotary cylinder, the telescopic drive component 4 is a telescopic cylinder, and the clamping jaw 5, the slide seat 3, the sliding structure and the center axis of the cylinder are located on the same straight line, so that the linear sliding accuracy and stability of the clamping jaw 5 are higher.

[0028] The present invention also provides a drill bit processing device, including the above-mentioned manipulator for taking and placing the drill bit, which can effectively prevent the slide or the clamping claw from rotating and offsetting during the movement of the support seat, thereby ensuring the accuracy of clamping and placing the drill bit, avoiding frequent adjustments and maintenance in the later stage, improving work efficiency and stability, and only needing to set up a set of sliding structures, making the overall structure of the manipulator simpler and saving structural costs.

[0029] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims shall fall within the scope of protection of the present invention.
