Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor processing technology, and in particular to a motor shaft hole drilling and tapping device. Background Technology
[0002] Currently, the traditional method for machining motor shaft holes generally involves using a saw to cut round steel bars to the length of the motor shaft. The cut shaft blank is then placed on a milling machine for end face and center hole machining. Finally, the motor shaft is drilled and tapped on a drilling machine. This traditional method involves many steps, each requiring manual clamping and machining. Furthermore, multiple clamping and positioning operations affect machining accuracy, easily reducing both efficiency and precision. Utility Model Content
[0003] In view of the defects existing in the prior art, the technical problem to be solved by this utility model is to provide a motor shaft hole drilling and tapping device that combines loading and unloading, center hole machining and deep hole machining processes.
[0004] To solve the above-mentioned technical problems, the present invention provides a motor shaft hole drilling and tapping device, including a frame, a rotatable feeding plate on the frame, and a feeding plate drive motor for driving the feeding plate to rotate. The feeding plate is provided with three workpiece clamping fixture groups for clamping workpieces. The three workpiece clamping fixture groups are symmetrically arranged around the axis of the feeding plate. Each workpiece clamping fixture group includes one workpiece clamp at the front and one at the back. Each workpiece clamp is composed of one clamping block on the left and one on the right that can slide left and right. The feeding plate is fixed with a clamping guide rail for guiding the two clamping blocks of the workpiece clamp to slide left and right, and a split-opening drive hydraulic cylinder for driving the clamping blocks to slide. The clamping blocks are mounted on the clamping guide rail in a sliding fit manner. The frame is provided with a limiting baffle on the front and rear sides of the top of the feeding tray, and the rear limiting baffle is provided with a pushing cylinder for pushing the workpiece. The frame is equipped with a deep hole machining device and a center hole drilling device that can slide back and forth, and a main guide rail for guiding the deep hole machining device and the center hole drilling device to slide back and forth. The deep hole machining device and the center hole drilling device are respectively arranged on the left and right sides of the feeding tray.
[0005] The motor shaft hole drilling and tapping device provided by this utility model utilizes a rotatable feeding tray structure to transport workpieces to various workstations, and continuously and synchronously processes feeding, center hole machining, and deep hole machining, which can accelerate processing efficiency.

Detailed Implementation
[0007] The embodiments of this utility model are described in further detail below with reference to the accompanying drawings. However, these embodiments are not intended to limit this utility model. Any similar structures or variations thereof that adopt this utility model should be included in the protection scope of this utility model. The commas in this utility model all indicate the relationship between and.
[0008] like Figures 1-2 As shown in the figure, the motor shaft hole drilling and tapping device provided in this embodiment of the utility model includes a frame 1, on which a rotatable loading plate 2 is provided, and a loading plate drive motor 25 for driving the loading plate to rotate. The loading plate 2 is provided with three workpiece clamping fixture groups for clamping workpieces (workpieces are motor shafts to be processed). The three workpiece clamping fixture groups are symmetrically arranged around the axis of the loading plate. Each workpiece clamping fixture group includes one workpiece clamp 22 at the front and one at the back. Each workpiece clamp is composed of one clamping block 222 on each side that can slide left and right. The loading plate 2 is fixed with a clamping guide rail 221 for guiding the two clamping blocks 222 of the workpiece clamp to slide left and right, and a split-and-join drive hydraulic cylinder (not shown in the figure) for driving the clamping blocks 222 to slide. The clamping blocks 222 are mounted on the clamping guide rail 221 in a sliding fit manner. The frame 1 has a limiting baffle 23 on the front and rear sides of the top of the feeding tray 2, and the rear limiting baffle 23 is equipped with a pushing cylinder 24 for pushing the workpiece. The frame 1 is equipped with a deep hole processing device 12 and a center hole drilling device 13 that can slide back and forth, and a main guide rail 11 for guiding the deep hole processing device 12 and the center hole drilling device 13 to slide back and forth. The deep hole processing device 12 and the center hole drilling device 13 are respectively arranged on the left and right sides of the loading tray 2.
[0009] In this embodiment of the present invention, the deep hole processing device and the center hole drilling device are both existing technologies, used to process the required hole structure on the workpiece. The structure of these two devices is described in many patent documents, and will not be repeated in this embodiment.
[0010] The device provided in this embodiment of the utility model is suitable for machining motor shafts; In the initial state, the three workpiece fixture groups are located at three stations, namely the clamping station, the center hole machining station, and the deep hole machining station. At the clamping station, the external robot 4 moves the workpiece 3 (motor shaft to be processed) to the clamping station, and then starts the top cylinder 24 to push the workpiece 3 to its front end to abut against the front limit baffle 23. Then, the split-drive hydraulic cylinder drives the clamping blocks 222 of the two workpiece clamps of the workpiece clamping group at the clamping station to close and hold the workpiece 3, thus completing the clamping of the workpiece. At the center hole machining station, the center hole drilling device 13 drives the center hole drill bit to machine the center hole of the workpiece. At the deep hole machining station, the deep hole machining device 12 drives the deep hole drill bit to perform deep hole machining on the workpiece; After the clamping station, center hole machining station, and deep hole machining station have all completed their operations, drive the loading tray 2 to rotate 120 degrees. At this time, the workpiece from the original clamping station is transferred to the center hole machining station, the workpiece from the original center hole machining station is transferred to the deep hole machining station, and the workpiece from the original deep hole machining station is transferred to the clamping station. At this time, the external robot arm 4 first grabs the workpiece currently located at the clamping station, and then drives the clamping blocks 222 of the two workpiece clamping fixtures of the workpiece clamping fixture group currently located at the clamping station to release the workpiece 3. The external robot arm 4 can then remove the machined workpiece and transfer the subsequent workpiece for clamping. At the same time, center hole machining can be performed on the workpiece at the center hole machining station, and deep hole machining can be performed on the workpiece at the deep hole machining station. This process is repeated until all workpieces have been machined.
