Detailed Description
In order to make the technical scheme and advantages of the present utility model more apparent, the present utility model will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural view of a feeding device in an embodiment of the present utility model. As shown in fig. 1, in a specific embodiment of the present utility model, the feeding device may include: the device comprises an outer barrel 1, a transmission rod 2, a screw rod 10, a hand wheel 11, a screw joint 14, a nut assembly, a bearing group, a first thrust ball bearing 6 and a second thrust ball bearing 12;
a containing cavity is arranged in the outer cylinder 1;
the transmission rod 2 is arranged in the accommodating cavity; the front end of the transmission rod 2 is provided with a cavity; a clamping groove is formed in the inner wall of the front end of the cavity, and a circular groove is formed in the rear end of the cavity;
the screw joint 14 is arranged in the cavity, the front end of the screw joint 14 extends out of the cavity, the rear end of the screw joint 14 is abutted with the circular groove, and the second thrust ball bearing 12 is arranged in the circular groove and penetrates through and is fixed at the rear end of the screw joint 14;
a protrusion is arranged in the middle of the screw joint 14; a bearing group which penetrates through and is fixed on the screw joint 14 is arranged between the protruding part and the rear end of the cavity; a first thrust ball bearing 6 penetrating and fixed on the screw joint 14 is arranged between the protruding part and the clamping groove of the cavity;
a pressing piece 7 penetrating through the screw joint 14 is arranged in the clamping groove of the cavity;
the nut component is fixedly connected with the front end of the outer cylinder 1; the nut component is provided with a through hole; an internal thread is arranged on the inner wall of the through hole;
an external thread corresponding to the internal thread is arranged on the outer surface of the screw rod 10;
the front end of the screw rod 10 is fixedly connected with the hand wheel 11;
the rear end of the screw rod 10 passes through the through hole and is fixedly connected with the front end of the screw joint 14.
In using the above-described feeding device in the present application, the outer cylinder 1 may be fixed using a fixing device (e.g., a clamping device), and then the hand wheel 11 is rotated so that the screw 10 starts to rotate. Since the external thread on the outer surface of the screw 10 corresponds to the internal thread on the inner wall of the through hole of the nut assembly, and the nut assembly is fixedly connected with the front end of the outer cylinder 1, no movement occurs, the screw 10 will axially move along the axial direction of the screw 10 when the screw 10 rotates. The rear end of the screw rod 10 is fixedly connected with the front end of the screw rod joint 14, so that when the screw rod 10 rotates, the screw rod 10 drives the screw rod joint 14 to correspondingly rotate and axially move. The rear end of the screw joint 14 is abutted against a circular groove in the cavity at the front end of the transmission rod 2, the outer surface of the screw joint 14 is connected with the inner wall of the cavity at the front end of the transmission rod 2 through the bearing group, the first thrust ball bearing 6 and the second thrust ball bearing 12, the pressing piece 7 can press the first thrust ball bearing 6 on the protruding part of the screw joint 14, and the bearing group and the second thrust ball bearing 12 are also pressed in the cavity at the front end of the transmission rod 2 through the protruding part, so that when the screw joint 14 moves axially, the transmission rod 2 is driven to move axially, and accordingly, a boring rod arranged at the rear end of the transmission rod 2 moves axially. At the same time, the rotation generated by the screw joint 14 is eliminated by the bearing group, the first thrust ball bearing 6 and the second thrust ball bearing 12 which are arranged on the screw joint 14 in a penetrating way, so that the transmission rod 2 is not driven to rotate.
Therefore, when the feeding device is used, only the hand wheel 11 is required to be rotated in a first direction (for example, clockwise), and the screw rod 10 and the screw joint 14 can drive the transmission rod 2 to move in the backward axial direction (namely, in the horizontal left direction in fig. 1); and rotating the hand wheel 11 in a second direction (e.g., counter-clockwise) will drive the drive rod 2 through the screw 10 and screw joint 14 to move axially forward (i.e., horizontally to the right in fig. 1). At the same time, the transmission rod 2 only moves axially and does not rotate.
Therefore, in the technical solution of the present application, the feeding device may be disposed inside the boring bar (for example, the outer wall of the boring bar may be used as the housing 1 of the feeding device), and the feeding device may be disposed at the front end of the boring bar (for example, the rear end of the transmission bar 2 is fixedly connected to the front end of the boring bar). After the feeding device is installed, the boring bar can be pushed to move correspondingly axially only by rotating the hand wheel, and the radial movement of the tool bit arranged in the grooving tool is driven, so that the cutting processing of the cavity of the deep hole inner cavity is realized, and the problem that an external feeding mechanism in the prior art is complex to install can be effectively solved.
In addition, in the technical scheme of the application, due to the arrangement of the bearing group, the first thrust ball bearing and the second thrust ball bearing, the rotary motion of the screw rod and the screw rod joint can be effectively eliminated to realize the transmission of the screw rod, so that the transmission rod only axially moves and does not rotate.
In addition, in the technical solution of the present application, the feeding device described above may be implemented in a variety of specific implementations. The following describes the technical solution of the present application by taking one or more specific implementation manners thereof as an example.

the transition sleeve 8 comprises a plug-in part and a butt joint part; the inserting part is inserted into the accommodating cavity at the front end of the outer cylinder 1, and the rear end of the abutting part is connected with the front end of the outer cylinder 1; a through hole penetrating through the plug-in part and the butt joint part is formed in the transition sleeve 8;
the front end of the screw nut 9 is fixedly connected with the butt joint part of the transition sleeve 8, the rear end of the screw nut 9 is arranged in the through hole, and an inner thread is arranged on the inner wall of the rear end of the screw nut 9.
When the nut assembly is used, the connecting part of the transition sleeve 8 can be fixedly connected with the front end of the outer cylinder 1, and the rear end of the screw rod 10 can pass through the screw rod nut 9 to be fixedly connected with the front end of the screw rod joint 14. Wherein the external threads on the outer surface of the screw 10 may cooperate with the internal threads on the inner wall of the screw nut 9.
