This field often employs precision machining processes such as CNC milling and turning, and widely utilizes special processes such as wire EDM and electrical discharge machining to handle complex geometric features and high-hardness materials.

[0003] According to Chinese Patent No. CN216461788U, a small parts machining positioning fixture includes a clamping tube, a clamping cavity, multiple mounting holes, multiple cam grooves, multiple cams, multiple pressure plates, multiple mounting bolts, and multiple handles. The clamping tube has a clamping cavity inside, the depth of which is set according to the length of the blank and the length of the blank to be machined. The clamping tube wall has multiple mounting holes, and the side wall of the clamping tube has multiple cam grooves. The multiple mounting holes are respectively connected to the multiple cam grooves. The multiple cams are respectively installed and connected to one end of the multiple pressure plates. The multiple cams rotate in the multiple cam grooves through the multiple mounting bolts. The other end of the multiple pressure plates is provided with a handle.

[0004] In the above scheme, the clamping cavity is used to accommodate the parts to be processed, which still has the following disadvantages: the number of feeding cavities is limited, the number of parts to be processed at the station in a single processing is limited, which reduces the efficiency of part processing. Summary of the Invention

[0005] The purpose of this invention is to provide a batch clamping structure for processing small parts, in order to solve the problems of limited feeding chambers, limited number of parts to be processed at a single station, and reduced efficiency in parts processing.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a batch clamping structure for processing small parts, including a placement plate, a plurality of placement grooves on the top surface of the placement plate, a pressing plate on the top surface of the placement plate, a plurality of rotating holes on the top surface of the pressing plate, a plurality of threaded grooves on the top surface of the placement plate, a mounting bolt inserted into the rotating hole, the bottom end of the mounting bolt passing through the rotating hole and threadedly connected to the threaded groove, a plurality of forward drill holes on the top surface of the pressing plate, the central axis of the forward drill holes being the same straight line as the central axis of the placement grooves, and two auxiliary drill holes being formed on the inner wall of the forward drill holes.

[0007] Preferably, the bottom surface of the placement plate is provided with a mounting plate, the top surface of the mounting plate is fixed with a plurality of positioning pins, and the top surface of the placement plate is provided with a plurality of positioning holes, wherein the positioning pins are slidably inserted into the positioning holes.

[0008] Preferably, a base is provided below the mounting plate, and a plurality of support columns are fixed on the top surface of the base, with the top ends of the support columns fixed to the bottom surface of the mounting plate.

[0009] Preferably, the top surface of the base is provided with two drive motors, the two sides of the mounting plate are provided with receiving openings, the body of the drive motor is located inside the receiving opening, the top of the output shaft of the drive motor is detachably provided with a wedge, and the bottom surface of the wedge is provided with a downward slope.

[0010] Preferably, a fixing plate is fixed to the top of the output shaft of the drive motor, a fixing groove is provided on the bottom surface of the wedge, the fixing plate slides in conjunction with the fixing groove, a fixing hole is provided on the top surface of the wedge, a replacement bolt is inserted into the fixing hole, and the bottom end of the replacement bolt passes through the fixing hole and is threadedly connected to the fixing plate.

[0020] In use, the operator first places the small part into the placement slot 2. At this time, since the thickness of the small part is greater than the depth of the placement slot 2, part of the structure of the small part is exposed outside the placement slot 2 when the small part is inside the placement slot 2. Then the operator places the pressing plate 3 on the top surface of the placement plate 1 and uses the threaded connection of the mounting bolt 6 and the threaded groove 5 to apply a downward force to the pressing plate 3, so that the small part can be firmly placed inside the placement slot 2. Then the operator drills the top surface of the small part using the main drilling hole 7 and the auxiliary drilling hole 8. Two placement plates 1 and pressing plates 3 are set up at one workstation and used alternately. The top surface of a placement plate 1 has forty-eight placement slots 2, which can fix multiple small parts for processing at one time. By alternating the use of two sets of placement plates 1 and pressing plates 3, batch clamping of parts to be processed can be achieved, increasing the efficiency of parts processing.

[0021] like Figure 2 and Figure 3As shown, a mounting plate 9 is provided on the bottom surface of the placement plate 1, and a number of positioning pins 10 are fixed on the top surface of the mounting plate 9.

A base 12 is provided below the mounting plate 9, and a number of support columns 13 are fixed on the top surface of the base 12. The top of the support columns 13 is fixed to the bottom surface of the mounting plate 9.

[0022] During use, after the placement plate 1 and pressing plate 3 are assembled, the staff will use two handles 22 to grab the placement plate 1 and place it on the top surface of the mounting plate 9. At the same time, the positioning pin 10 is inserted into the positioning hole 11 to achieve the assembly and positioning of the placement plate 1 and the mounting plate 9, which increases the stability of the placement plate 1 on the top surface of the mounting plate 9.

[0023] like Figure 2 and Figure 4 As shown, two drive motors 14 are provided on the top surface of the base 12. Receiving openings 15 are provided on both sides of the mounting plate 9. The body of the drive motor 14 is located inside the receiving opening 15. A wedge 16 is detachably provided at the top of the output shaft of the drive motor 14. A downward inclined surface 17 is provided on the bottom surface of the wedge 16. A fixing plate 18 is fixed at the top of the output shaft of the drive motor 14. A fixing groove 19 is provided on the bottom surface of the wedge 16. The fixing plate 18 and the fixing groove 19 slide together. A fixing hole 20 is provided on the top surface of the wedge 16. A replacement bolt 21 is inserted into the fixing hole 20. The bottom end of the replacement bolt 21 passes through the fixing hole 20 and is threadedly connected to the fixing plate 18.

[0024] In use, when the placement plate 1 is placed on the top surface of the mounting plate 9, the drive motor 14 works and uses the rotating output shaft to drive the wedge 16 to rotate. The rotating wedge 16 will drive the lower inclined surface 17 at the bottom to press the placement plate 1 on the mounting plate 9, thereby locking the placement plate 1 on the mounting plate 9 and preventing the placement plate 1 from falling off. If the wedge 16 is damaged, the staff can disassemble the fixing plate 18 and replace the bolt 21 to replace the intact wedge 16, which increases the convenience of the staff to replace the wedge 16.
