Problems solved by technology

But, the problem that this thread deburring machine exists is: 1, this equipment can only finish the deburring processing of one end thread portion of a workpiece at a time, and the processing efficiency still needs to be improved; Displacement occurs, which affects the machining accuracy; 3. It is difficult to guarantee the concentricity between the workpiece (especially for shaft parts) and the die mounting sleeve (die)

Embodiment 1

[0029] The deburring machine tool for shaft parts comprises a frame 1, a fixture 2, a tool assembly 3, a sliding seat 4, a pressing mechanism, a driving mechanism and a feeding mechanism.

[0030] Specifically, as figure 1 As shown, the clamp 2 includes a base plate 22 and two positioning blocks 21, the base plate 22 is fixed on the frame 1, and a slide groove 221 is provided on the base plate 22, and the bottom of the positioning block 21 has a guide block 214 that matches the slide groove 221. Block 21 is positioned with base plate 22 by locking screws. As a preferred solution, the sliding groove 221 is a dovetail groove, and the positioning block 21 can slide along the sliding groove 221 . Such as Figure 4As shown, the positioning block 21 has a positioning portion 211 arranged vertically, and the two positioning portions 211 are arranged parallel to each other. The positioning portion 211 is provided with a positioning notch 212, and the side walls of the positioning no...

Embodiment 2

[0036] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, the driving mechanism includes a spindle box 5 and a drive motor 6 on the sliding seat 4, and the spindle box 5 is provided with The driving main shaft 51 is connected with the output shaft of the driving motor 6 through a gear transmission mechanism. The tool assembly 3 includes a connecting shaft 31, a sleeve 32 and a spring 33. The connecting shaft 31 is fixedly connected to the driving spindle 51. The sleeve 32 is sleeved on the connecting shaft 31 and positioned circumferentially with the connecting shaft 31. The front end of the sleeve 32 is fixed There is a die 16, a retaining edge 321 is provided on the outer surface of the sleeve 32, a positioning boss 311 is arranged on the connecting shaft 31, one end of the spring 33 leans against the retaining edge 321, and the other end leans against the positioning boss 311. ...

Embodiment 3

[0038] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, the pressing mechanism includes a clamping cylinder and clamping jaws, the clamping jaws are hinged on the frame 1, clamping The piston rod of the air cylinder is connected with the jaws and can drive the jaws to swing around the hinge, and the jaws also have a clamping portion matching the outer peripheral surface of the shaft parts. The shaft parts are positioned through the clamping part of the jaws, and the positioning is more reliable.

Abstract

The invention provides a deburring machine tool for shaft parts, and belongs to the technical field of machinery. The deburring machine tool for the shaft parts solves the problem that an existing deburring machine tool for the shaft parts cannot conduct deburring on the two ends of the shaft parts simultaneously. The deburring machine tool for the shaft parts comprises a rack. A fixture for positioning the shaft parts is fixed to the rack, a pressing mechanism for pressing the shaft parts is arranged above the fixture, the two sides of the fixture are provided with sliding seats respectively, and all the sliding seats are provided with cutting tool assemblies and further provided with driving mechanisms for driving the cutting tool assemblies to rotate forward and reversely. A feeding mechanism capable of driving the sliding seat to be close to or away from the fixture is further arranged on the rack. According to the deburring machine tool for the shaft parts, the cutting tool assemblies arranged on the two sides of the fixture conduct deburring on the thread parts of the shaft parts positioned on the fixture simultaneously, automatic deburring is achieved, and the deburring machine tool is higher in production and machining efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a deburring machine tool, in particular to a deburring machine tool for double-threaded shaft parts. Background technique [0002] Shaft parts are commonly used parts in the processing and production of mechanical equipment. They are mainly used to support transmission parts, transmit torque and bear loads. According to the needs of use, some shaft parts need to be designed with anti-rotation flat squares to prevent the shaft from rotating. The processing technology of this kind of parts can only be milled to stop the flat square after the thread processing is completed. After milling the flat square, there will be more burrs at the junction of the thread and the flat square. These burrs seriously affect the assembly and surface quality of the parts. Some parts Both ends are also designed with anti-rotation flat squares and threads. How to quickly and effectively remove these bu...
