Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 6, the present cutting tool for center feed for cutting rough machining of a shell 120 having a stub bar 110 at an intermediate position includes: a base 100; a positioning assembly 200 fixed on the base 100, the positioning assembly 200 having a fixing seat 210; a pressing assembly 300 movably disposed above the positioning assembly 200, the pressing assembly 300 having: the pressing block 310 is used for movably abutting the shell 120 between the fixed seat 210 and the pressing block 310; the limiting plate 320 is connected with the pressing block 310, the limiting plate 320 is sleeved on the outer wall of the stub bar 110, and the limiting plate 320 is used for enabling the stub bar 110 to move downwards when the stub bar 110 is separated from the shell 120; and a cutting assembly 400 movably disposed on the base 100 and located at one side of the positioning assembly 200, wherein a cutting tool 410 is movably disposed on the cutting assembly 400, and the cutting tool 410 is used for separating the stub bar 110 from the housing 120.
The cutting tool provided by the invention is used for completing the separation of the stub bar 110 and the shell 120 by adopting a rough machining mode, the positioning assembly 200, the pressing assembly 300 and the cutting assembly 400 are all arranged on the base 100, before the cutting process is carried out, a worker is required to place the shell 120 on the fixed seat 210, meanwhile, the shell 120 is abutted between the fixed seat 210 and the pressing block 310 by utilizing the downward movement of the pressing block 310 above the fixed seat 210, one side of the pressing block 310 close to the end part of the shell 120 is connected with the limiting plate 320, the limiting plate 320 is provided with the U-shaped groove 321, and the U-shaped groove 321 is used for being sleeved on the stub bar 110 from top to bottom.
The pressing block 310 and the fixing seat 210 are both provided with a plurality of clamping grooves 211, the clamping grooves 211 are used for axially and movably arranging the shell 120 between the pressing block 310 and the fixing seat 210, and a gap is formed between the limiting plate 320 and the shell 120 placed in the clamping grooves 211 all the time.
A plurality of engaging grooves 211 for placing the housing 120 are disposed on the pressing block 310 and the fixing base 210, it should be noted that the pressing block 310 and the engaging grooves 211 on the fixing block are both designed according to the shape of the outer wall of the housing 120, and because a large cutting force needs to be prevented from deforming the housing 120 during the cutting process of rough machining, a movable space needs to be reserved for the housing 120 while the housing 120 is being fixed and pressed, therefore, when each engaging groove 211 on the pressing block 310 and the fixing base 210 is designed, the width of each engaging groove 211 is slightly larger than that of the protruding block on the housing 120, so that when the pressing block 310 presses the housing 120 between the fixing base 210 and the pressing block 310, the cutting tool 410 performs axial cutting on the housing 120, the shell 120 can generate a certain displacement along the axial cutting direction by virtue of the larger width of the engaging groove 211, the design is performed in order to avoid that the fixed block and the pressing block 310 fix the shell 120 immovably, the cutting tool 410 deforms the shell 120 due to a larger cutting force, except that the engaging groove 211 is designed to enable the shell 120 to have a position space moving along the cutting direction, a movable space of the shell 120 also needs to be ensured between the pressing block 310 and the fixed seat 210, therefore, the material of the pressing block 310 is preferably a flexible material, so that when the pressing block 310 abuts against the shell 120 on the fixed seat 210, a certain buffering force exists between the pressing block 310 and the shell 120, and the phenomenon of deformation in the cutting process due to over-tight fixation of the shell 120 is avoided; the position where the position limiting plate 320 is placed also needs to be further limited, in order to ensure that the movement interference of the position limiting plate 320 is not caused when the housing 120 is displaced in the axial direction, a gap is always formed between the position limiting plate 320 and the housing 120 placed in the engaging groove 211, and the purpose of the design is to ensure that even if the housing 120 moves to the limit position of the engaging groove 211 in the cutting direction, the housing 120 in the engaging groove 211 still does not interfere with the position limiting plate 320 at this time, and thus the housing 120 does not contact with the position limiting plate 320 to deform due to the displacement generated in the engaging groove 211.
The pressing assembly 300 further includes a connecting plate 330 and an upper pressing plate 340, the connecting plate 330 is located above the pressing block 310 and connected to the pressing block 310, a compression spring 350 is connected between the upper pressing plate 340 and the connecting plate 330, and the compression spring 350 is used for providing a buffering force when the pressing block 310 abuts against the housing 120.
In order to further enhance the buffering force between the pressing block 310 made of flexible material and the housing 120, the connecting plate 330 is connected above the pressing block 310, and the compression spring 350 is connected between the connecting plate 330 and the upper pressing plate 340. It should be noted that the upper pressing plate 340 is connected with an external driving device, when the upper pressing plate 340 moves downwards, the upper pressing plate 340 gives a certain buffering force to the connecting plate 330 through the compression spring 350, and because the pressing block 310 is fixedly connected with the connecting plate 330, the buffering force generated to the connecting plate 330 when the upper pressing plate 340 moves downwards indirectly gives the pressing block 310, so that a certain loosening force is provided between the pressing block 310 and the housing 120, and the deformation of the housing 120 caused by the over-tightening fixation of the pressing block 310 to the housing 120 in the cutting process is avoided.
The positioning assembly 200 is symmetrically provided with guide blocks 220, each guide block 220 is provided with a guide inclined surface 221, and the guide inclined surfaces 221 facilitate the housing 120 to be placed on the fixing seat 210.
