Detailed Description

As shown in fig. 1 to 3, a pin 9 removing device includes a pin 9 and a removing joint for connecting the pin 9, where the removing joint further includes: the clamping device comprises a first clamping body 1 and a second clamping body 2, wherein the first clamping body 1 and the second clamping body 2 are oppositely arranged at intervals, and a clamping cavity 3 which can be sleeved into the pin shaft 9 is formed at the intervals; a fastening body 4, the fastening body 4 can penetrate the first clamping body 1 and the second clamping body 2 to enable the clamping cavity 3 to be abutted against the pin shaft 9; the rotary joint 5 is fixedly connected with the first clamping body 1 and the second clamping body 2; the transition joint 6, transition joint 6 one end with rotary joint 5 links to each other, and the other end links to each other with a rotation axis 7, rotation axis 7 still is equipped with can drive rotation axis 7 pivoted driving piece 8.

As a preferred embodiment of the present application, the first clamping body 1 and the second clamping body 2 are configured as a combination of a round table and a cylinder with diameters which are increased from end to end and then unchanged, that is, the first clamping body 1 and the second clamping body 2 are arranged at intervals, the middle is provided with a spacing surface, but the end parts of the two clamping bodies shrink towards the center, and the design is convenient for adjusting tightness degree of the fastener so as to prevent the pin shaft 9 from being damaged due to overlarge fastening force.

In a specific example of the above embodiment, the spacing surface formed by spacing the first clamping body 1 and the second clamping body 2 forms the clamping cavity 3 with a hole diameter slightly larger than that of the pin shaft 9 at the center, and after the first thread is arranged at the lower end of the combined body, the second thread matched with the first thread is arranged on the inner surface of the fastening body 4. In this embodiment, the fastening body 4 may be configured such that a combination of a truncated cone and a cylinder penetrates in the middle, so that the fastening body 4 may pass through the first clamping body 1 and the second clamping body 2 to tighten the pin 9. The amount of this tightening force can be controlled by the depth at which the second thread is screwed into the first thread.

As a preferred embodiment of the above embodiment, cutting may be performed on the truncated cone surface of the fastening body 4 to form an inclined tangential plane 10, so as to facilitate manual screwing of the assembly.

As a preferred embodiment of the application, the first clamping body 1 is connected with the bottom end of the second clamping body 2 and then is connected with the transition rotating shaft, so that the processing of the taking-out device is facilitated, the deformation of the first clamping body 1 and the second clamping body 2 can be coordinated with each other, and the integrity is improved.

As a preferred embodiment of the application, the rotation shaft 7 is rotatably connected to the transition shaft in the present application. Because the split mold needs to be installed between the transition rotating shaft and the driving piece 8 in actual use, the pin shaft 9 is positioned after the installation step of the split mold finishes the turning, and the transition rotating shaft is rotationally connected with the rotating shaft 7, so that the rotating shaft 7 cannot be driven to rotate by the rotation generated when the fastening body 4 fastens the first clamping body 1 and the second clamping body 2, the driving piece 8 can be prevented from loosening in this way, namely, when the taking-out device needs to be installed into the positioning pin shaft 9, the transition rotating shaft can be fixed by a spanner, and then the fastening body 4 can be rotated by hands or another spanner, and because the transition rotating shaft and the fastening body 4 are simultaneously forced, the rotation process of the fastening body 4 cannot drive the rotating shaft 7/the driving piece 8 to rotate, so that the split mold cannot be loosened.

As a preferred embodiment of the present application, the transition shaft is formed by the rotation mode of the rotation shaft 7 being a flat rotation, the driving member 8 and the rotation shaft 7 are connected by screw threads, and the pin 9 is pulled out by a pulling-out device in the prior art after the driving member 8 rotates to a predetermined position.
