Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing process equipment, and specifically relates to a multi-station self-aligning top clamping drilling and milling pneumatic fixture. Background Technology

[0002] In the process of machining and manufacturing, a strip-shaped copper workpiece is usually processed. This workpiece needs to be machined with three holes, and the drilling and milling depth to the end face of the hole requires extremely high tolerance accuracy. In the early days, manual calipers were mostly used for machining, and it was difficult to guarantee the accuracy requirements. This was time-consuming, labor-intensive, and inefficient, and could not meet the needs of mass production. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a multi-station self-aligning top clamping drilling and milling pneumatic clamp with simple structure, convenient clamping, and high production efficiency.

[0004] The technical solution adopted by this utility model to solve the technical problem is: a multi-station self-aligning top clamping drilling and milling pneumatic chuck, including a base plate, vertical plates, support columns, and a panel. Its characteristic is that a vertical plate is provided at each of the front and rear ends of the horizontal base plate, and multiple support columns are provided on the base plate between the two vertical plates. A panel is fixed on the two vertical plates and the multiple support columns, and multiple workpiece processing positions are provided on the panel. Each workpiece processing position is provided with an arched support cover, which is fixed to the panel. A pneumatic manual valve one is provided on the front vertical plate, and a pneumatic manual valve two is provided on the rear vertical plate. The pneumatic manual valve two is connected. The upper lifting cylinder is controlled by a pneumatic control system. The upper lifting cylinder is fixed on the base plate. One side of the upper lifting cylinder is connected to air hole one and air hole two. The piston rod of the upper lifting cylinder is connected to the lifting block. A fixed top block is provided above the lifting block. The workpiece is placed on the fixed top block. The pneumatic manual control valve one controls the straightening cylinder. The straightening cylinder is fixed on the lifting block. One side of the straightening cylinder is connected to air hole three and air hole four. The piston rod of the straightening cylinder is connected to the connecting rod, which drives the connecting rod to move up and down. The connecting rod is connected to the rotating shaft. The rotating shaft is fixed on the fixed seats at both ends of the lifting block. The rotating shaft is fixedly connected to the linkage rod. The linkage rod is connected to the straightening claw. The straightening claw straightens and clamps the workpiece.

[0005] The beneficial effects of this utility model are as follows: the multi-station self-aligning top clamping drilling and milling pneumatic chuck has been transformed from the original single-station manual chuck into a multi-station self-aligning pneumatic clamping device, which can simultaneously process workpieces in multiple drilling and milling stations. The multiple aligning claws controlled by the aligning cylinder can clamp the workpiece horizontally, and the top cylinder pneumatically controls the workpiece to move upward through the limit of the arched support cover fixed on the panel, so that the workpiece is clamped vertically, thus firmly clamping the workpiece. Through all-round pneumatic clamping, it saves manpower and time costs, reduces the time for clamping and alignment, improves the processing accuracy and production efficiency, and enables multi-station processing with one clamping and alignment, which greatly increases the production capacity.

Detailed Implementation

[0010] Example, see attached document Figure 1 , 2 The multi-station self-aligning top clamping drilling and milling pneumatic fixture has two vertical plates 2 at the front and rear ends on a horizontal base plate 1. Multiple support columns 11 are installed on the base plate between the two vertical plates 2. The upper surfaces of the vertical plates 2 and the support columns 11 are flush. A panel 3 is fixed on the two vertical plates 2 and the multiple support columns 11. Eight workpiece processing positions are located on the panel 3. Each workpiece processing position is fixed with an arched support cover 8, the two ends of which are fixed to the panel 3. A pneumatic manual valve 4 is installed on the front vertical plate, and a pneumatic manual valve 10 is installed on the rear vertical plate 2. The pneumatic manual valve 10 controls the top clamping cylinder 13 at each position via an air circuit. The top clamping cylinder 13 is fixed to the base plate 1. One side of the top clamping cylinder 13 is connected to air holes 13-1 and 13-2. When air hole 13-1 is working, the top clamping cylinder 13 moves downwards, and air hole 13-2 moves downwards. The upper cylinder 13 moves upward, and the piston rod of the upper cylinder 13 is connected to the lifting block 14. A fixed top block 16 is provided above the lifting block 14, and the workpiece 17 is placed above the fixed top block 16. The pneumatic hand-operated valve 4 controls the straightening cylinder 12 of each station through the air circuit. The straightening cylinder 12 is fixed on the lifting block 14. One side of the straightening cylinder 12 is connected to the air hole 3 12-1 and the air hole 4 12-2. The working straightening cylinder 12 of the air hole 3 12-1 performs the releasing action of the straightening claw 7, and the working straightening cylinder 12 of the air hole 4 12-2 performs the straightening and clamping action of the straightening claw 7. The piston rod of the straightening cylinder 12 is connected to the connecting rod 15, which drives the connecting rod 15 to move up and down. The connecting rod 15 is connected to the rotating shaft 5, which is fixed on the fixed seats 9 at both ends of the lifting block 14. The rotating shaft 5 is fixedly connected to the linkage rod 6, which is connected to the straightening claw 7. The straightening claw 7 straightens and clamps the workpiece 17.

[0011] The method of using the multi-station self-aligning top clamping drilling and milling pneumatic chuck is as follows: With the aligning jaw 7 in the outward-opening state, place the strip-shaped copper workpiece 17 above the fixed top block 16 of each station. The center hole to be machined on the workpiece 17 is placed directly below the machining hole of the support cover 8. Align the center hole to be machined on the copper workpiece 17 through the machining hole of the support cover 8. The other two holes of the copper workpiece are located on both sides of the support cover 8. Start the pneumatic hand-operated valve 4, and the air port 12-2 will work. The aligning cylinder 12 will move downward, and the piston rod of the aligning cylinder 12 will drive the connecting rod 15. The connecting rod 15 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the linkage rod 6 and the straightening claw 7, causing the straightening claw 7 to grip and straighten the workpiece 17 inward. Then, the pneumatic manual valve 10 is activated, and the air hole 13-2 is pressurized, causing the upper cylinder 13 to move upward. The piston rod of the upper cylinder 13 drives the lifting block 14 to move upward, and the lifting block 14 drives the fixed top block 16 on it to move upward. The fixed top block 16 moves upward, causing the copper workpiece 17 on it to move upward and press against the support cover 8, so that the workpiece is gripped in the vertical direction, thereby gripping the workpiece in all directions and thus processing the workpiece. This fixture has eight workstations and can process eight workpieces simultaneously. After the drilling and milling of the eight workpieces is completed, the pneumatic hand-operated valve 210 is activated, and the air port 13-1 is pressurized. The upper cylinder 13 moves downward, causing the workpiece to disengage from the limit of the support cover 8. Then, the pneumatic hand-operated valve 4 is activated, and the air port 312-1 is activated. The connecting rod 15 drives the rotating shaft 5 to drive the straightening claw 7, causing the straightening claw 7 to disengage from the workpiece, thereby releasing the grip on the workpiece 17. The processed workpiece is then removed from the workstation, and the next batch of workpieces to be processed is placed in, thus enabling mass production.
