Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in FIGS. 1-2, a workpiece boring fixture comprises a screw assembly 1 and a fixture 2, the screw rod component 1 comprises a motor 11, a screw rod 12 and a mounting seat 13, two ends of the screw rod 12 are movably connected with two ends of the mounting seat 13, the motor 11 is arranged on the mounting seat 13, the output end of the motor 11 is connected with one end of the screw rod 12, the clamp 2 comprises a hydraulic plunger 21, a base 22, a baffle plate 23, a movable pressing piece 24 and a clamping plate 25, the screw rod 12 movably penetrates through the base 22, the bottom end of the base 22 is abutted with the mounting seat 13, the hydraulic plunger 21 penetrates through the base 22, the output end of the hydraulic plunger 21 is detachably connected with the movable pressing piece 24 positioned at the top end of the base 22, the baffle 23 and the two clamping plates 25 are arranged at the upper end of the base 22 side by side, and a gap is arranged between the two clamping plates 25. Specifically, in the present embodiment, in use, an operator mounts the workpiece 100 on the base 22, and causes the end of the workpiece 100 to abut against the baffle plate 23, and the front end of the workpiece 100 is clamped in the gap between the two clamping plates 25, thereby preventing the workpiece 100 from shifting when the boring tool bores a hole, which results in a decrease in boring accuracy. Further, in order to prevent the workpiece 100 from "squeezing out" from the middle of the two clamping plates 25 during boring, the workpiece 100 is pressed against the base 22 using the hydraulic plunger 21 in cooperation with the movable pressing member 24. Further, when the hydraulic plunger 21 drives the movable pressing member 24 to press down, the other end of the movable pressing member 24 abuts against the surface of the workpiece 100, so that the workpiece 100 is prevented from slipping out from the middle of the two clamping plates 25. Further, when boring is finished and the workpiece 100 needs to be replaced, the hydraulic plunger 21 drives the movable pressing piece 24 to move upwards, so that the end of the movable pressing piece 24 is separated from the workpiece 100, an operator can replace the workpiece 100, the operation is simple and convenient, and the efficiency is high. It should be noted that, in the present embodiment, the screw rod assembly 1 is used to drive the fixture 2 with the workpiece 100 to approach or depart from the boring cutter, when the motor 11 works, the screw rod 12 can be driven to rotate on the mounting seat 13 in situ, and the base 22 and the screw rod 12 are spirally connected, so that when the screw rod 12 rotates, the base 22 can make reciprocating linear motion on the screw rod 12, so that the workpiece 100 approaches or departs from the boring cutter. Further, base 22 and mount pad 13 are the activity butt, consequently, base 22 can make a round trip to displace along mount pad 13, rocks when preventing the displacement of base 22, appears the deviation during leading to the bore hole, and then effectively improves the bore hole precision.

As shown in fig. 2, a threaded hole 251 and a mandrel 252 are arranged on one side of two adjacent clamping plates 25, and the mandrel 252 is detachably mounted in the threaded hole 251. Specifically, in this embodiment, the mandrel 252 is spirally installed in the threaded hole 251, so that an operator can adjust the length of the mandrel 252 extending into the threaded hole 251 according to the diameter of the columnar workpiece 100, so that the two mandrels 252 can clamp the workpiece 100 correspondingly, and the workpiece 100 is prevented from shifting, resulting in bore hole dislocation.

As shown in fig. 2 to 3, a pressing head 241 is further disposed at one end of the movable pressing member 24 away from the hydraulic plunger 21, and a plurality of protrusions 2411 are disposed on an end surface of the pressing head 241. Specifically, in this embodiment, when hydraulic plunger 21 drives movable pressing piece 24 and pushes down, pressing head 241 can with work piece 100 surface butt, compress tightly work piece 100 then, prevent that work 100 from rocking when the bore hole, set up a plurality of archs 2411 on the terminal surface of pressing head 241 with work piece 100 contact, improve the frictional force between pressing head 241 and the work piece 100. It should be noted that the pressing head 241 is made of silicone, so as to avoid that the pressing head 241 is in hard contact with the workpiece 100, which results in scratches being left on the surface of the workpiece 100.

As shown in fig. 2 to 3, a pin shaft hole 242 is formed at one end of the movable pressing member 24 connected to the hydraulic plunger 21. Specifically, in this embodiment, the pin shaft penetrates through the pin shaft hole 242, so as to integrally connect the pressing member 24 and the hydraulic plunger 21, thereby facilitating the detachment of the movable pressing member 24.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
