Detailed Description
A screw seat milling fixture is further described below with reference to the accompanying drawings.
The utility model provides the following scheme: the milling fixture for the thread seat comprises a screw sleeve 1, a sleeve 3 and a base 2. Threads are arranged at two ends of the screw sleeve 1, one end of the screw sleeve is connected with the sleeve 3, and the screw sleeve 1 is fixed on the base 2 through the cooperation of the screw sleeve and the sleeve; the other end is matched and connected with the threaded base 2 of the workpiece to be processed, so as to finish the clamping of the workpiece to be processed. By increasing the diameter of one end of the clamp base 2, the threaded sleeve 1 and the sleeve 3 are prevented from moving axially after being matched on the base 2. The clamp base 2 is provided with a locating pin 4 on the end face of one large diameter end thereof for locating a workpiece to be machined.
The specific structure of the screw seat milling fixture is shown in fig. 1-6, a sleeve 3 is sleeved outside a base 2, a screw sleeve 1 for installing a workpiece is installed in the sleeve 3, and the workpiece is installed in the screw sleeve 1 and fixedly connected with the screw sleeve 1. The outer circumferential surface of the bottom of the screw sleeve 1 is provided with threads which are connected with the base 2 through threads, and the inner circumferential surface of the top of the screw sleeve 1 is provided with threads which are connected with a workpiece through threads. The top of the sleeve 3 is provided with an internal thread matched with the screw sleeve 1, and the inner surface of the bottom of the screw sleeve 1 is provided with a shoulder seat 8. One end of the base 2 is provided with a shaft shoulder 5 matched with a shaft shoulder seat 8 of the screw sleeve 1, and the top of the shaft shoulder 5 is provided with a positioning pin 4. The outside of the screw sleeve 1 is provided with a first mounting hole 6, and the outside of the sleeve 3 is provided with a second mounting hole 7.
The screw sleeve 1 and the sleeve 3 respectively pass through the center holes of the screw sleeve and the sleeve to be penetrated on the base 2, and the screw sleeve and the sleeve are connected and fixed through threaded fit. Wherein the diameter of one end of the base 2 is larger than the diameter of the other end, and the shoulder 5 is used for preventing the screw sleeve 1 and the sleeve 3 from moving axially when being arranged on the base 2.
The working principle and the using flow of the utility model are as follows: when the screw thread base is used, firstly, a screw thread base 2 piece to be processed is connected with a screw sleeve 1; secondly, positioning a to-be-machined piece by using a positioning pin 4 on the end face of the large-diameter end of the base 2; finally, the internal thread of the sleeve 3 and the external thread of the screw sleeve 1 are utilized to carry out matched connection, and the assembly of the clamp and the workpiece to be machined is completed. Wherein, the outside of swivel nut 1 sets up mounting hole one 6, and sleeve 3 outside sets up mounting hole two 7. The installation is convenient and reliable; and the threaded sleeve 1 can be replaced according to the thread sizes of the to-be-machined parts of the thread seats with different sizes, so that the universality of the clamp is enhanced, the machining cost is saved, and the working efficiency is improved.
The foregoing has shown and described the basic principles, principal structures and advantages of the utility model. It will be appreciated by those skilled in the art that variations and modifications in size and orientation, etc. may be made to the utility model without departing from the spirit and scope of the utility model, and that such variations and modifications are within the scope of the utility model as claimed.
