Description

Technical Field

[0001] This utility model relates to the field of coupling processing, specifically a drilling device for coupling processing. Background Technology

[0002] A coupling, also known as a shaft coupling, is a mechanical component used to securely connect the driving shaft and driven shaft in different mechanisms to rotate together and transmit motion and torque. Sometimes it is also used to connect shafts with other parts (such as gears, pulleys, etc.). It is usually composed of two halves, which are connected by keys or tight fits and fastened to the two shaft ends. The two halves are then connected together in some way. Couplings can also compensate for the misalignment (including axial misalignment, radial misalignment, angular misalignment, or combined misalignment) between the two shafts due to manufacturing and installation inaccuracies, deformation during operation, or thermal expansion; as well as mitigate shock and absorb vibration. When machining couplings, drilling equipment is often required to drill holes in them.

[0003] However, the fixing components in existing drilling devices for coupling processing are not easy to adjust and can only fix couplings of the same size, thus limiting their applicability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drilling device for coupling processing, which solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for coupling processing, comprising a worktable, a gantry frame, and a base. The gantry frame is mounted on the worktable, and the base is mounted at the center of the worktable. The base includes a cam and a fixed sleeve. A pair of fixed sleeves are fixedly mounted on the base. A movable rod is slidably mounted inside each pair of fixed sleeves. A sliding rod is fixedly mounted at one end of each movable rod. A pair of cams are rotatably mounted on the base. A connecting rod is axially connected to the most convex point of each pair of cams. A sliding sleeve is fixedly mounted at the other end of the connecting rod. The sliding sleeve is slidably mounted on the sliding rod. A clamping plate is fixedly mounted at the other end of the movable rod.

[0006] Preferably, a pair of motors are fixedly mounted on the base, and each of the motors has a driving bevel gear fixedly mounted on its drive end. A pair of driven bevel gears that mesh with the driving bevel gears are rotatably mounted on the base, and the driven bevel gears are fixedly connected to the cam.

[0007] Preferably, a cylinder is fixedly installed on the top of the gantry frame, and a drill bit is fixedly installed on the telescopic end of the cylinder.

[0008] Preferably, the pair of clamps are V-shaped clamps.

[0009] Beneficial effects

[0010] This utility model provides a drilling device for coupling processing, which has the following advantages:

[0011] 1. With the cam installed, the rotation of the cam can drive the connecting rod and the cam hinge to make a circular motion around the center of the cam, which in turn drives the sliding sleeve to move on the sliding rod, and then drives the sliding rod and the moving rod to move, which in turn drives the clamping plate to move. The distance between a pair of clamping plates can be adjusted to clamp and fix couplings of different sizes, and the application range is wide.

[0012] 2. The motor is installed and started to drive the driving bevel gear to rotate. The driving bevel gear meshes with the driven bevel gear to drive the driven bevel gear to rotate, thereby driving the cam to rotate. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Wherein, directional terms such as "upper" and "lower" mentioned herein are used in conjunction with... Figure 1 The orientation is used as a reference.

[0017] Please see Figures 1-2 This utility model provides a technical solution: a drilling device for processing couplings, including a worktable 1, a gantry frame 2, and a base 3. The gantry frame 2 is installed on the worktable 1, and the base 3 is installed at the center of the worktable 1. It includes a cam 7 and a fixed sleeve 11. A pair of fixed sleeves 11 are fixedly installed on the base 3. A moving rod 13 is slidably installed in each of the pair of fixed sleeves 11. A slide rod 10 is fixedly installed at one end of the moving rod 13. A pair of cams 7 are rotatably installed on the base 3. A connecting rod 8 is axially connected to the most convex point of the pair of cams 7. A slide sleeve 9 is fixedly installed at the other end of the connecting rod 8. The slide sleeve 9 is slidably installed on the slide rod 10. A clamping plate 12 is fixedly installed at the other end of the moving rod 13.

[0018] With the cam 7 installed, the rotation of the cam 7 can drive the connecting rod 8 and the hinge of the cam 7 to make a circular motion around the center of the cam 7, thereby driving the sliding sleeve 9 to move on the sliding rod 10, which in turn drives the sliding rod 10 and the moving rod 13 to move, thereby driving the clamping plate 12 to move. The distance between a pair of clamping plates 12 can be adjusted to clamp and fix couplings of different sizes, making it applicable to a wide range of applications.

[0019] Furthermore, a pair of motors 4 are fixedly installed on the base 3, and each of the motors 4 has a driving bevel gear 5 fixedly installed on its driving end. A pair of driven bevel gears 6 that mesh with the driving bevel gears 5 are rotatably installed on the base 3, and the driven bevel gears 6 are fixedly connected to the cam 7.

[0020] The motor 4 is installed and started to drive the active bevel gear 5 to rotate. The active bevel gear 5 meshes with the driven bevel gear 6 to drive the driven bevel gear 6 to rotate, thereby driving the cam 7 to rotate.

[0021] Furthermore, a cylinder 15 is fixedly installed on the top of the gantry frame 2, and a drill bit 14 is fixedly installed on the telescopic end of the cylinder 15.

[0022] By installing a cylinder 15, starting the cylinder 15 causes the telescopic end of the cylinder 15 to extend and retract, which in turn drives the drill bit 14 to rise and fall, thus facilitating drilling of the coupling. By installing the drill bit 14, starting the drill bit 14 allows drilling of the coupling.

[0023] Furthermore, the pair of clamping plates 12 are V-shaped clamping plates 12. By setting the clamping plates 12 to V-shape, it is convenient to fix couplings of different sizes.

[0024] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0025] The working principle and usage process of this utility model are as follows: In use, the coupling is placed on the base 3, and the motor 4 is started to drive the driving bevel gear 5 to rotate. The driving bevel gear 5 meshes with the driven bevel gear 6, which in turn drives the driven bevel gear 6 to rotate, thereby driving the cam 7 to rotate. This causes the connecting rod 8 to make a circular motion around the center of the cam 7, thereby driving the sliding sleeve 9 to move on the sliding rod 10, which in turn drives the sliding rod 10 and the moving rod 13 to move, thereby driving the pair of clamping plates 12 to move, adjusting the distance between the pair of clamping plates 12 until the coupling is clamped and fixed. Then, the cylinder 15 is started, and the telescopic end of the cylinder 15 extends, causing the drill bit 14 to descend to a position that is convenient for drilling the coupling. The drill bit 14 is then started to drill the coupling.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
