Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a push rod clamp for CNC machining. Background Technology

[0002] When machining push rods using CNC machining, the traditional clamping method involves using equal-height pads and flat-jaw vises stacked together, along with a pressure plate for clamping. Figure 1 Due to the varying lengths of the push rods, the height of the leveling blocks needs frequent adjustment. Each adjustment requires a straightening and correction using flat-jaw pliers. Occasionally, excessive overlap errors occur, necessitating reassembly and re-verification, resulting in a significant waste of auxiliary time and severely reducing processing efficiency. Utility Model Content

[0005] As a preferred embodiment of this utility model, the clamping mechanism is used to clamp a push rod with a round head. The clamping mechanism includes: a clamping handle (tool holder), a spring collet (ER collet) mounted on the clamping handle, and a fastening nut fitted on the spring collet. The bottom of the clamping handle is fixed to the upper end of the base by bolts, and the through hole in the clamping handle corresponds to the position of the V-shaped guide opening at the upper end of the mounting cavity. The top of the clamping handle is fixed to the spring collet. The head of the push rod is placed into the clamping hole of the spring collet and the fastening nut is used to clamp the head of the push rod in the clamping hole of the spring collet. After being clamped and fixed, the push rod is automatically centered during CNC machining.

[0006] As a preferred embodiment of this utility model, the clamping mechanism is used to clamp a top rod with a semi-circular or square head. The clamping mechanism includes: a square base, a clearance hole vertically opened in the square base, and a threaded connection hole horizontally opened on the square base and passing through the clearance hole. Two clamping screws are threadedly connected in the threaded connection hole, and the ends of the clamping screws are provided with clamping heads. The top rod head is placed into the clearance hole and the clamping heads of the two clamping screws are used to clamp the top rod head in the clearance hole. After being clamped and fixed, the top rod is automatically centered during CNC machining.

[0007] As a preferred embodiment of this invention, the mounting cavity inside the base is provided with openings on both sides, and the openings are used to install adjustment pads.

[0008] As a preferred embodiment of this utility model, the spring clip includes an outer sleeve and an inner sleeve. The outer ring of the outer sleeve is connected to a fastening nut, and the inner ring of the outer sleeve has a V-shaped opening. The inner sleeve corresponds to the shape of the V-shaped opening and is embedded in the outer sleeve. The inner sleeve is used to clamp the head position of the push rod.

[0009] As a preferred embodiment of this utility model, the clearance through hole is a stepped two-section hole, the diameter of the upper through hole is larger than the diameter of the lower through hole, and the clamping heads of the two clamping screws are placed inside the through hole at the upper end of the clearance through hole.

[0010] The beneficial effects of this utility model are as follows: By using two types of clamping mechanisms in conjunction with the base, it is possible to quickly clamp and position top rods of different specifications. Moreover, the overall structure is simple and compact and can be installed as a whole component, avoiding the cumbersome steps of traditional splicing clamping. Attached Figure Description

The first clamping mechanism 3 is used to clamp the top rod 2 with a round head. The first clamping mechanism 3 includes: a clamping handle (tool holder) 301, a spring collet (ER collet) 302 installed on the clamping handle 301, and a fastening nut 303 fitted on the spring collet 302. The bottom of the clamping handle 301 is fixed to the upper end of the base 1 by bolts, and the through hole in the clamping handle 301 corresponds to the position of the V-shaped guide port 5 at the upper end of the mounting cavity 4. The top of the clamping handle 301 is fixed to the spring collet 302. The head of the top rod 2 is placed into the clamping hole of the spring collet 302 and the head of the top rod 2 is clamped in the clamping hole of the spring collet 302 by the fastening nut 303. After being clamped and fixed, the top rod 2 is automatically centered in CNC machining.

[0021] Furthermore, in this embodiment, the mounting cavity 4 inside the base 1 has openings on both sides for installing the adjustment pads 6, so as to facilitate the placement of adjustment pads 6 of different sizes.

[0022] Furthermore, the spring sleeve in this embodiment includes an outer sleeve and an inner sleeve. The outer ring of the outer sleeve is connected to the fastening nut 303. The inner ring of the outer sleeve has a V-shaped opening. The inner sleeve corresponds to the shape of the V-shaped opening and is embedded in the outer sleeve. The inner sleeve is used to clamp the head position of the push rod 2.
