Description

Technical Field

[0001] This utility model belongs to the field of air motor head manufacturing technology, and in particular relates to an air motor head pressure cover fixing fixture. Background Technology

[0002] An air motor, also known as a pneumatic motor or air-powered motor, is a device that converts the pressure energy of compressed air into rotational mechanical energy. The most widely used pneumatic motors in pneumatic transmission are vane type and piston type. During the manufacturing process of an air motor, screws are used in conjunction with a cap to seal the head of the air motor to keep the inside of the air motor sealed.

[0003] Currently, when installing the offset cover on the air motor head, there is no positioning fixture for the offset cover. Instead, a fixing fixture is used to fix the position of the air motor head, and then the offset cover is placed on the air motor head. Finally, a screw gun is used to directly fix the offset cover to the air motor head with screws. Since the air motor head is sealed by a rubber O-ring under the offset cover, if the offset cover is not pressed flat when screwing, it will cause the rubber O-ring to be crushed, resulting in air leakage from under the offset cover. This greatly affects the yield rate of the air motor offset cover installation.

[0004] Therefore, we propose an air motor head pressure cover fixing fixture to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art that when installing the offset cover on the air motor head, there is no positioning fixture for the offset cover, which causes the offset cover to not be pressed flat when screwing the screw, resulting in damage to the rubber O-ring and air leakage from under the offset cover, affecting the yield rate. The proposed air motor head offset cover fixing fixture is designed to address this issue.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An air motor head offset cover fixing fixture includes a base plate, a positioning plate fixedly connected to the upper surface of the base plate, an air motor head body disposed above the base plate, the back of the air motor head body contacting the front of the positioning plate, a cylinder fixedly connected to the upper surface of the base plate, the cylinder being disposed on the back of the positioning plate, a connecting frame fixedly connected to the telescopic end of the cylinder, a positioning platform fixedly connected to the bottom surface of the connecting frame, an offset cover disposed on the upper surface of the air motor head body, four mounting screws internally threaded onto the offset cover, the bottom end of each mounting screw penetrating into the interior of the air motor head body, each mounting screw being threadedly connected to the air motor head body, a pad fixedly connected to the upper surface of the base plate, the inner wall of the pad contacting the bottom surface of the air motor head body, adjusting support blocks disposed on both sides of the pad, the top ends of the two adjusting support blocks contacting the bottom surface of the air motor head body, and a pneumatic valve and a regulating valve fixedly connected to the upper surface of the base plate respectively.

[0008] Preferably, the back of the positioning plate is fixedly connected to two reinforcing ribs, and the bottom surfaces of the two reinforcing ribs are fixedly connected to the upper surface of the base plate.

[0009] Preferably, a mounting base is fixedly connected to the upper surface of the base plate, a fixing plate is fixedly connected to the upper surface of the mounting base, a limiting frame is fixedly connected to the upper surface of the fixing plate, a connecting plate is movably hinged inside the limiting frame, a handle is fixedly connected to the upper surface of the connecting plate, a movable frame is movably hinged to the outer surface of the connecting plate, a top rod is slidably connected inside the limiting frame, one end of the top rod contacts the front of the air motor head body, and the other end of the top rod is movably hinged to the inner wall of the movable frame.

[0010] Preferably, the fixing plate has four positioning bolts internally threaded together, the bottom end of each positioning bolt penetrating into the interior of the mounting base, and each positioning bolt is threadedly connected to the mounting base.

[0011] Preferably, a reinforcing frame is fixedly connected to the outer surface of the connecting frame, and the inner wall of the reinforcing frame is fixedly connected to the outer surface of the cylinder extension end.

[0012] Preferably, two slide rods are fixedly connected to the upper surface of the positioning plate, and both slide rods are slidably connected inside the connecting frame.

[0013] Preferably, the pneumatic valve has four fastening bolts connected to its internal thread, the bottom end of each fastening bolt penetrating into the interior of the base plate, and each fastening bolt being threadedly connected to the base plate.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] By incorporating pads, adjusting support blocks, and positioning plates, the position of the air motor head body can be initially determined. After the offset cover is placed on the air motor head body, a pneumatic valve and adjusting valve, along with a cylinder, move the connecting frame up and down. This movement of the connecting frame causes the positioning platform to move downwards. Once the positioning platform contacts the offset cover, the cylinder, in conjunction with the positioning platform, provides downward pressure to the offset cover from the center position, further securing its position on the air motor head body. This prevents damage to the rubber ring at the bottom of the offset cover during subsequent tightening of the mounting screws, ensuring the accuracy of the offset cover and preventing air leakage at the connection point between the offset cover and the air motor head body. This system not only positions the air motor head body during offset cover installation but also provides a positioning fixture for the offset cover, ensuring it is flattened when the mounting screws are tightened, thus guaranteeing a high success rate for the installation between the offset cover and the air motor head body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4This embodiment provides an air motor head pressure cover fixing fixture, which includes a base plate 1. A positioning plate 2 is fixedly connected to the upper surface of the base plate 1. An air motor head body 3 is disposed above the base plate 1. The back of the air motor head body 3 is in contact with the front of the positioning plate 2. Two reinforcing ribs 13 are fixedly connected to the back of the positioning plate 2. The bottom surfaces of the two reinforcing ribs 13 are fixedly connected to the upper surface of the base plate 1. The reinforcing ribs 13 can increase the connection between the positioning plate 2 and the base plate 1, making the connection between the positioning plate 2 and the base plate 1 tighter and more reliable, and improving the pressure bearing capacity of the positioning plate 2.

[0023] A mounting base 14 is fixedly connected to the upper surface of the base plate 1. A fixing plate 15 is fixedly connected to the upper surface of the mounting base 14. A limiting frame 16 is fixedly connected to the upper surface of the fixing plate 15. A connecting plate 17 is movably hinged inside the limiting frame 16. A handle 18 is fixedly connected to the upper surface of the connecting plate 17. A movable frame 19 is movably hinged to the outer surface of the connecting plate 17. A top rod 20 is slidably connected inside the limiting frame 16. One end of the top rod 20 contacts the front of the air motor head body 3. The other end of the top rod 20 is movably hinged to the inner wall of the movable frame 19. By manually turning the handle 18, in conjunction with the connecting plate 17 and the movable hinge relationship between the connecting plate 17 and the limiting frame 16, the top rod 20 can be slid inside the limiting frame 16 through the movable frame 19 until one end of the top rod 20 contacts the front of the air motor head body 3. At this time, the position of the air motor head body 3 can be further fixed by the mechanical dead point principle in conjunction with the positioning plate 2, which further increases the positioning stability of the air motor head body 3.

[0024] A cylinder 4 is fixedly connected to the upper surface of the base plate 1. The cylinder 4 is located on the back of the positioning plate 2. Four positioning bolts 21 are threadedly connected to the inside of the fixing plate 15. The bottom end of each positioning bolt 21 penetrates into the interior of the mounting base 14. Each positioning bolt 21 is threadedly connected to the mounting base 14. The positioning bolts 21 can increase the tightness of the connection between the fixing plate 15 and the mounting base 14, making the connection between the fixing plate 15 and the mounting base 14 tighter and more reliable.

[0025] A connecting frame 5 is fixedly connected to the telescopic end of cylinder 4. A positioning platform 6 is fixedly connected to the bottom surface of the connecting frame 5. A bias cover 7 is provided on the upper surface of the air motor head body 3. Four mounting screws 8 are threaded inside the bias cover 7. The bottom end of each mounting screw 8 penetrates into the interior of the air motor head body 3. Each mounting screw 8 is threadedly connected to the air motor head body 3. A reinforcing frame 22 is fixedly connected to the outer surface of the connecting frame 5. The inner wall of the reinforcing frame 22 is fixedly connected to the outer surface of the telescopic end of cylinder 4. The reinforcing frame 22 can increase the connection strength between the connecting frame 5 and the telescopic end of cylinder 4, making the connecting frame 5 less prone to deformation during use.

[0026] A pad 9 is fixedly connected to the upper surface of the base plate 1. The inner wall of the pad 9 is in contact with the bottom surface of the air motor head body 3. Two slide rods 23 are fixedly connected to the upper surface of the positioning plate 2. Both slide rods 23 are slidably connected inside the connecting frame 5. The slide rods 23 can increase the accuracy of the vertical movement of the connecting frame 5 without affecting its vertical movement.

[0027] Adjustable support blocks 10 are provided on both sides of the pad 9. The tops of the two adjustable support blocks 10 are in contact with the bottom surface of the air motor head body 3. The upper surface of the base plate 1 is fixedly connected to the pneumatic valve 11 and the regulating valve 12 respectively. The cylinder 4, the pneumatic valve 11 and the regulating valve 12 are all connected to each other through the air hose. The pneumatic valve 11 has four fastening bolts 24 internally threaded. The bottom end of each fastening bolt 24 penetrates into the interior of the base plate 1. Each fastening bolt 24 is threaded to the base plate 1. The fastening bolts 24 can improve the connection stability between the pneumatic valve 11 and the base plate 1, making the pneumatic valve 11 less prone to loosening and ensuring the stable use of the pneumatic valve 11.

[0028] The working principle of this utility model is as follows: In use, firstly, the air source is connected to the pneumatic valve 11 and regulating valve 12 via a hose, allowing high-pressure gas to smoothly enter the cylinder 4 under the control of the pneumatic valve 11 and regulating valve 12. When it is necessary to fix the offset cover 7 onto the air motor head body 3, the position of the air motor head body 3 can be initially positioned using the pad 9 in conjunction with the adjusting support block 10 and the positioning plate 2. Then, manually turning the handle 18, in conjunction with the connecting plate 17 and the movable hinge relationship between the connecting plate 17 and the limit frame 16, allows the movable frame 19 to drive the push rod 20 to slide inside the limit frame 16 until one end of the push rod 20 contacts the front of the air motor head body 3. At this point, the position of the air motor head body 3 can be further fixed using the mechanical dead point principle in conjunction with the positioning plate 2. Then, after placing the offset cover 7 on the air motor head body 3, the position is further fixed using the pneumatic valve 11 in conjunction with the regulating valve... 12. The cylinder 4 can be used to drive the connecting frame 5 to move up and down. When the connecting frame 5 moves up and down, it can drive the positioning table 6 to move down. When the positioning table 6 moves down to contact the offset cover 7, the positioning table 6, in conjunction with the cylinder 4, can provide downward pressure to the offset cover 7 from the middle position, thereby flattening and fixing the offset cover 7 to the position on the air motor head body 3. This ensures that when the screws 8 are tightened using a screw pneumatic gun, the rubber ring at the bottom of the offset cover 7 will not be damaged due to the offset cover 7's displacement, thus ensuring the accuracy of the offset cover 7. This also ensures that there will be no air leakage at the connection between the offset cover 7 and the air motor head body 3. When the offset cover 7 is installed, the air motor head body 3 can not only be positioned, but also has a positioning fixture for the offset cover 7, so that the offset cover 7 can be flattened when the installation screws 8 are tightened, thus ensuring the installation yield between the offset cover 7 and the air motor head body 3.
