[0027] Specifically, when the nozzle connecting rod 4 is installed on the top end of the core shaft 2, the nozzle connecting rod 4 can be rotated, so that its right side can first be against the first screw of the side positioning component 5, and then the second screw of the tightening component 6 is tightened to achieve squeezing of the outer side of the product, ensuring that the nozzle connecting rod 4 blank is partially fixed, and then the clamping screw 10 and the washer are set on the top of the core shaft 2, so that the clamping screw 10 relies on the washer to press the nozzle connecting rod 4 partially and fix it, thereby promoting the tightening of various parts of the nozzle connecting rod 4 blank and completing the clamping work.
[0028] Furthermore, after the components of the lateral positioning assembly 5 are adjusted, the position of the first screw is fixed; while the second screw of the tightening assembly 6 is in a movable state, which is used to loosen or tighten when clamping the product.
[0029] Furthermore, the first pin and the second pin are respectively threaded with threaded through holes, and the first screw and the second screw are respectively sleeved with matching washers, which are arranged between the screw head ends and the pins.
[0030] Furthermore, a core shaft through hole 8 is provided on one side of each clearance groove 11, and the core shaft through hole 8 is opened from the top to the bottom of the main board 1, and the bottom end of the core shaft 2 is clearance-fitted into the inside of the core shaft through hole 8.

[0036] Furthermore, a plurality of fastening screw through holes 9 for assembling with the rotating shaft of the machining center are respectively provided on both sides of the top of the main board 1. The main board 1 is fixedly connected with the rotating shaft of the machining center by fastening screws passing through the fastening screw through holes 9.
[0037] Specifically, this efficiency enhancement device fixes the mainboard 1 on the rotating axis of the machining center by fastening screws through the fastening screw holes 9, thereby realizing 360-degree rotation of the mainboard 1, and completing the processing of multiple surfaces of the workpiece by clamping it once, thereby improving efficiency to a certain extent.
[0038] The working principle and usage process of the present invention are as follows: before using the device, first pass the bottom end of the core shaft 2 through the core shaft through hole 8, and then thread the bottom end of the core shaft 2 through the tightening nut 3, so that the core shaft 2 can be stably installed on the main board 1, and then the pins of the side positioning component 5 and the tightening component 6 are interference fit in the corresponding pin holes 7, and the two screws are threaded through the corresponding pins respectively, and adjusted; and after adjustment, the first screw of the side positioning component 5 is in a fixed state, and the second screw of the tightening component 6 is in an active state, which is used to loosen or tighten when clamping the product, thereby fixing the main board 1 to the rotating shaft of the machining center through the fastening screw through the fastening screw through hole 9.

[0040] Finally, the device rotates 360 degrees driven by the rotating shaft of the machining center, so that the utility model only needs to clamp the nozzle connecting rod 4 blank once to achieve the technical effect of multi-process processing on different surfaces of the nozzle connecting rod 4 blank, shortening the processing cycle and improving the processing efficiency. In actual application, since there is no need to clamp the nozzle connecting rod 4 multiple times, the problem of error accumulation is avoided, and the product qualification rate can be increased from the previous 90% to 99%, which has certain practicality.
