Description

Technical Field

[0001] The invention relates to the field of air compressor assembly equipment, in particular to an air compressor screw positioning tooling equipment. Background Art

[0002] The full name of air compressor is air compressor, which is a device used to compress gas. Screw air compressors are divided into single-screw air compressors and twin-screw air compressors. Twin-screw air compressors are a double-shaft positive displacement rotary air compressor, which consists of a pair of parallel and mutually meshing male and female screws. The female screw is provided with spiral grooves at equal intervals along its circumference, and the male screw is provided with spiral bosses at equal intervals along its circumference. The insertion of the spiral boss of the male screw into the spiral groove of the female screw is called the meshing of the male and female screws.

[0003] When assembling a twin-screw air compressor, the male and female screws need to be aligned and meshed so as to test the rotation smoothness of the male and female screws before assembly. However, in the prior art, when assembling the male and female screws, a fixed clamp is usually used to clamp the screws, and then the operator manually adjusts the rotation angle of the male and female screws, and then moves the clamp to drive the male and female screws to align and mesh together.

[0004] The above-mentioned method of aligning and meshing the male and female screws can only fix and clamp the screws, which makes it difficult for the operator to adjust the angle of the screws, and is not conducive to the operator to observe the rotation angle of the two screws, so that the time for adjusting the angle of the screws is relatively long, thereby reducing the assembly efficiency of the screws, and when the fixed clamping method is used to clamp the screws, it is difficult to detect the smoothness of the rotation of the screws after the meshing, and the problem of rework is prone to occur after the screws are assembled, thereby further reducing the assembly efficiency of the screws. In addition, when the existing clamps are used to clamp the screws, the screws need to be inserted into the inside of the clamps, so that the operator needs to manually support the screws while operating the clamps to clamp the screws, which reduces the convenience of clamping and further reduces the assembly efficiency of the screws. Summary of the invention

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an air compressor screw positioning tooling equipment, including a base plate, a U-shaped frame is symmetrically and fixedly installed on the upper part of the base plate, and a clamping mechanism for moving and fixing the screw is provided on the U-shaped frame.

[0012] Preferably, the alignment component includes an insertion rod slidably arranged left and right in the middle part of the right support plate. A rotating sleeve is rotatably arranged in the middle part of the left support plate. A hexagonal column is slidably arranged left and right inside the rotating sleeve.

[0016] The beneficial effects of the present invention are as follows: 1. The present invention adopts a limit assembly to clamp and lock the screw, and at the same time the clamped screw can always rotate freely inside the limit assembly, which is convenient for the operator to adjust the angle of the screw, thereby increasing the assembly convenience of the operator and improving the assembly efficiency. After the screw rotating inside the limit assembly is aligned and meshed, the operator can detect the rotational meshing smoothness of the male and female screws when the screw is not installed into the casing, thereby avoiding the phenomenon of assembly rework and further improving the assembly efficiency.

[0017] 2. The present invention adopts an alignment component to assist the screw in alignment, so that the male and female screws can be rotated to a direct meshing angle, thereby eliminating the need for operators to repeatedly observe and adjust the angle of the screws, thereby improving the accuracy and efficiency of the screw alignment, further improving the efficiency of assembly, and preventing the male and female screws from colliding with each other during meshing, thereby avoiding damage to the screws.

[0018] 3. The present invention adopts a moving component to drive the limit component to change position, so that the limit component can be located on the upper side of the bracket plate in the initial state, so that the screw can be directly placed inside the limit component from top to bottom, which is convenient for the operator to clamp the screw. When aligning, the moving component can drive the screw to move to engagement through the limit component. When the screw is connected to the casing, the moving component can drive the limit component to directly disengage from the screw, which further simplifies the operation of the operator and further improves the efficiency of assembly.

[0031] The embodiments of the present invention will be described in detail below. The described embodiments are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0032] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 7, an air compressor screw positioning tooling device, including a bottom plate 1. On the upper part of the bottom plate 1, U-shaped frames 11 are symmetrically and fixedly installed on the left and right. A clamping mechanism 2 for moving and fixing the screw is arranged on the U-shaped frame 11. The clamping mechanism 2 includes a moving plate 21 that is slidably arranged longitudinally on the U-shaped frame 11 and is close to the center side of the bottom plate 1. On the upper parts of the two transverse sections of the U-shaped frame 11 and on the side close to the center of the bottom plate 1, track members 22 are fixedly installed. The two track members 22 on the same left or right side are arranged symmetrically front and back. A support plate 23 is slidably arranged between the two track members 22 on the same left or right side. On the side of the support plate 23 close to the center of the bottom plate 1, a limiting component 24 for clamping the screw is arranged. The limiting component 24 includes sliding plates 241 that are symmetrically arranged front and back and are slidably arranged on the side of the support plate 23 close to the center of the bottom plate 1. On the side of the sliding plate 241 close to the center of the bottom plate 1, a C-shaped frame 242 is fixedly installed. Along the circumference of the C-shaped frame 242, abutting wheel frames 243 are arranged at equal intervals. The abutting wheel frames 243 are slidably connected to the C-shaped frame 242 along the radial direction of the C-shaped frame 242. On the side of the abutting wheel frame 243 close to the axis position of the C-shaped frame 242, an abutting wheel 244 is rotatably arranged.

[0033] In the initial state, the C-shaped frame 242 is located at the upper part of the support plate 23, and the opening of the C-shaped frame 242 faces upward. When it is necessary to align and assemble the male and female screws, the operator places the female screw and the male screw inside the C-shaped frames 242 on the right and left sides respectively, so that the rotating shafts of the screws simultaneously enter the interiors of the two front and back opposite C-shaped frames 242, so that the rotating shafts of the screws abut against the sides of the abutting wheels 244 at the corresponding positions.

[0034] Refer to Figure 2 and Figure 3 , on the sliding plate 241, a side abutting part 246 for abutting against the side of the screw is arranged. The side abutting part 246 includes an adjusting frame 2461 that is slidably arranged on the side of the sliding plate 241 away from the center of the support plate 23. On the side of the adjusting frame 2461 close to the C-shaped frame 242, an abutting roller 2462 is rotatably arranged. On the upper part of the adjusting frame 2461, an inclined panel 2464 is fixedly installed. On the upper part of the side of the sliding plate 241 away from the center of the support plate 23, a toothed plate 2463 is slidably arranged up and down. A helical spring for pushing the toothed plate 2463 downward is arranged between the toothed plate 2463 and the sliding plate 241. A pushing spring for pushing the adjusting frame 2461 in the direction away from the C-shaped frame 242 is arranged between the adjusting frame 2461 and the sliding plate 241.

[0035] After the screw is placed inside the C-shaped frame 242, the operator manually pushes the adjustment frame 2461 upward, so that the adjustment frame 2461 drives the abutting roller 2462 to move upward synchronously, and when the adjustment frame 2461 moves upward, it drives the inclined plate 2464 thereon to move upward synchronously, so that the inclined plate 2464 intermittently pushes the corresponding position of the tooth plate 2463 in the direction away from the center position of the bottom plate 1, and when the abutting roller 2462 moves upward to the side of the screw, the tooth plate 2463 is stuck on the outside of the inclined plate 2464 under the push of the coil spring, and then the external force on the adjustment frame 2461 is removed, so that the pushing spring pushes the adjustment frame 2461 downward, and the adjustment frame 2461 drives the inclined plate 2464 to abut against the side of the tooth plate 2463, so that the abutting roller 2462 remains in the adjusted position.

[0036] See also Figure 2 , Figure 3 and Figure 5 The bracket plate 23 is provided with a centering portion 247 for driving the two sliding plates 241 on the same side to move closer to or away from each other. The centering portion 247 includes a synchronous plate 2471 rotatably arranged in the middle of the bracket plate 23 away from the center of the bottom plate 1. The front and rear sections of the synchronous plate 2471 are both hinged with a connecting plate 2472. The end of the connecting plate 2472 away from the synchronous plate 2471 is hinged to the sliding plate 241 at the corresponding position. The rear part of the bracket plate 23 is rotatably provided with an adjusting threaded rod 2473, and the adjusting threaded rod 2473 is threadedly connected to the connecting plate 2472 at the corresponding rear position.

[0037] When the abutment roller 2462 moves to the side of the screw, the operator manually turns the adjusting threaded rods 2473 on the left and right sides, and the adjusting threaded rods 2473 drive the rear connecting plate 2472 to move forward, and the rear connecting plate 2472 drives the rear sliding plate 241 to move forward synchronously, and the rear connecting plate 2472 pushes the synchronous plate 2471 to rotate, and the synchronous plate 2471 drives the front sliding plate 241 to move backward synchronously through the front connecting plate 2472, so that the sliding plates 241 on the front and rear sides are close to each other, so that the sliding plate 241 drives the abutment roller 2462 to abut against the side of the screw through the adjusting frame 2461, and then the abutment roller 2462 pushes the screw to move to the center position between the front and rear sliding plates 241, and clamps and locks the front and rear positions of the screw.

[0038] See also Figure 2 , Figure 3 and Figure 4The C-shaped frame 242 is provided with a linkage part 245 for all the abutting wheel frames 243 on the same C-shaped frame 242 to move synchronously. The linkage part 245 includes a driven rack 2451 fixedly installed on the abutting wheel frame 243 away from the center of the base plate 1. The C-shaped frame 242 is provided with driving gears 2452 rotatably arranged at equal intervals along its circumference. The driving gears 2452 are meshed with the driven racks 2451 at corresponding positions. The driving gears 2452 on the same C-shaped frame 242 are connected to each other through a synchronous belt. A one-way threaded column 2453 is rotatably provided on the C-shaped frame 242. The one-way threaded column 2453 is threadedly connected to the abutting wheel frame 243 at the upper part of the C-shaped frame 242 away from the center of the base plate 1.

[0039] After the front and rear positions of the screw are locked, the one-way threaded column 2453 is manually rotated, and the one-way threaded column 2453 drives the abutment wheel frame 243 connected thereto to move toward the axial position of the C-shaped frame 242, and at the same time, the abutment wheel frame 243 drives the driven rack 2451 thereon to move synchronously, and the driven rack 2451 drives the driving gear 2452 meshing with it to rotate, and the driving gear 2452 drives other driving gears 2452 on the same C-shaped frame 242 to rotate synchronously through the synchronous belt, so that all the driving gears 2452 rotate synchronously, and then all the driven racks 2451 drive the abutment wheel frames 243 at the corresponding positions to move synchronously toward the axial position of the C-shaped frame 242, and the abutment wheel frame 243 drives the abutment wheel 244 thereon to abut against the outer side of the rotating shaft of the screw, thereby locking the screw in the coaxial position of the C-shaped frame 242.

[0040] It should be noted that, since the abutment wheel 244 is freely rotatably arranged on the abutment wheel frame 243, when the abutment wheel 244 is pressed against the outer surface of the rotating shaft of the screw, the screw can still drive the abutment wheel 244 to rotate, thereby facilitating the adjustment of the angle of the screw.

[0041] It should also be noted that when all the abutment wheels 244 abut against the outer side of the rotating shaft of the screw, the two upper abutment wheels 244 are located on the upper side of the rotating shaft of the screw, so that the screw cannot move up and down, thereby locking the screw in a coaxial position of the C-shaped frame 242.

[0042] See also Figure 2 , Figure 5 and Figure 6 The left and right bracket plates 23 are respectively provided with alignment components 25 for aligning the male and female screws. The alignment component 25 includes a rotating sleeve 252 rotatably arranged in the middle of the left bracket plate 23. A hexagonal column 253 is slidably arranged inside the rotating sleeve 252. A follower plate 254 is fixedly installed on the right side of the hexagonal column 253. Alignment rods 255 are fixedly installed at the four corners on the right side of the follower plate 254. The rotating sleeve 252 is fixed in position by screws.

[0043] The operator pre-rotates the follower plate 254 according to the inclination of the screw, and the follower plate 254 drives the rotating sleeve 252 to rotate synchronously through the hexagonal column 253, so that the follower plate 254 drives the alignment rod 255 to correspond to the inclination of the screw, thereby facilitating the insertion of the alignment rod 255 into both sides of the spiral boss of the male screw, and then fixes the position of the rotating sleeve 252 by screws, thereby fixing the angle of the follower plate 254.

[0044] Continue reading Figure 2 , Figure 5 and Figure 6 The alignment component 25 also includes an insertion rod 251 which is slidably arranged in the middle of the right bracket plate 23. A conical rubber wheel 2551 is rotatably arranged on the outer side of the alignment rod 255. The diameter of the conical rubber wheel 2551 gradually increases from right to left. Active springs are arranged between the follower plate 254 and the left bracket plate 23 and between the insertion rod 251 and the right bracket plate 23.

[0045] When the screw is placed inside the C-shaped frame 242, the screw presses the insertion rod 251 and the alignment rod 255 downward by its own gravity, so that the alignment rod 255 compresses the active spring at the corresponding position through the follower plate 254, and the insertion rod 251 compresses the active spring at the corresponding position. After the screw is clamped and locked, the operator rotates the female screw and the male screw respectively, so that the spiral boss on the male screw rotates to the position between the follower plate 254, so that the follower plate 254 drives the alignment rod 255 to move upward under the push of the active spring at the corresponding position, and then the alignment rod 255 drives the conical rubber wheel 2551 to abut against the two sides of the spiral boss of the male screw. When the follower plate 254 moves up to the highest position, the spiral boss of the male screw is located directly above the follower plate 254. At this time, the conical rubber wheels 2551 all abut against the side surfaces of the spiral boss of the male screw, thereby fixing the rotation angle of the male screw.

[0046] When the female screw is rotated until the spiral groove thereon is directly above the insertion rod 251, the insertion rod 251 is pushed upward into the spiral groove of the female screw by the active spring at the corresponding position, thereby fixing the rotation angle of the female screw.

[0047] It should be noted that the conical rubber wheel 2551 can adapt to the spiral bosses of male screws of different thicknesses. When the spiral bosses of the male screws are thicker, the upper part of the conical rubber wheel 2551 contacts the spiral bosses of the male screws, so that the upward movement distance of the follower plate 254 is shorter. Otherwise, the upward movement distance of the follower plate 254 is longer.

[0048] It should also be noted that when one point of the spiral boss of the male screw is opposite to the follower plate 254 and one point of the spiral groove of the female screw is opposite to the insertion rod 251, the spiral boss of the male screw is at a position corresponding to the spiral groove of the female screw, that is, at this time the male screw and the female screw are in a position where they can engage with each other.

[0049] See also Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 A moving assembly 26 for driving the bracket plate 23 to move is provided on the moving plate 21. The moving assembly 26 includes a notch plate 262 fixedly installed on the upper part of the moving plate 21. A fixed support plate 263 is fixedly installed on the upper part of the bracket plate 23. The fixed support plate 263 gradually tilts from bottom to top in a direction away from the center of the bottom plate 1. A sliding column 264 is fixedly installed on the upper part of the fixed support plate 263. The sliding column 264 cooperates with the notch of the notch plate 262. An active bidirectional screw 265 is rotatably provided on the bottom plate 1. The two threaded sections of the active bidirectional screw 265 are respectively threadedly connected to the two moving plates 21.

[0050] A driven support plate 231 is fixedly installed on the side of the bracket plate 23 away from the center of the base plate 1 and is symmetrical front to back. Two movable columns 232 are fixedly installed on the side of the driven support plate 231 away from the center of the bracket plate 23. The lower part of the track member 22 is a linear groove structure, and the upper part of the track member 22 is a quarter-circular groove structure on the side away from the center of the base plate 1. The radius of the circular groove structure of the track member 22 is equal to the spacing between the two movable columns 232, and the two movable columns 232 slide simultaneously inside the track member 22 at the corresponding position.

[0051] After the rotation angle of the screw is fixed, the operator manually rotates the active bidirectional screw 265 to drive the movable plates 21 on the left and right sides to approach each other, and the movable plate 21 pushes the fixed support plate 263 toward the center position of the base plate 1 through the notch plate 262, and the fixed support plate 263 pushes the bracket plate 23 at the corresponding position, so that the bracket plate 23 rotates 90° around the sliding column 264 away from the side of the bracket plate 23, so that the bracket plate 23 drives another sliding column 264 to rotate along the circular groove of the track member 22 to the inside of the linear groove of the track member 22 through the driven support plate 231. When the bracket plate 23 rotates, the bracket plate 23 drives the sliding column 264 to move upward along the track of the notch plate 262 through the fixed support plate 263.

[0052] When the support plate 23 drives the screw rod to rotate through the C-shaped frame 242 until the support plate 23 is on the side close to the center of the bottom plate 1, the two moving columns 232 are located in the same horizontal plane, and the two moving columns 232 are simultaneously located inside the linear grooves of the track members 22 at the corresponding positions. Then, the moving plate 21 drives the support plate 23 to continue moving, so that the support plate 23 moves horizontally in the direction close to the center of the bottom plate 1 through the moving columns 232, and further enables the support plate 23 to drive the two screw rods to move and engage with each other through the C-shaped frame 242.

[0053] Refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.10 As shown in FIGS. 14 to 15, a disc plate 256 is fixedly installed on the left side of the hexagonal column 253 and the right side of the insertion rod 251. A pulling portion 257 for pulling the disc plate 256 is provided on the U-shaped frame 11. The pulling portion 257 includes an L-shaped pulling plate 2571 slidably arranged left and right on the longitudinal section of the U-shaped frame 11. An adjusting bidirectional screw rod 2572 is rotatably arranged on the longitudinal sections of the two U-shaped frames 11 together. The two threaded sections of the adjusting bidirectional screw rod 2572 are respectively threadedly connected to the L-shaped pulling plates 2571 on the left and right sides.

[0054] The operator pre-rotates the adjusting bidirectional screw rod 2572 according to the distance that needs to be moved when the screw rods are engaged, so that the adjusting bidirectional screw rod 2572 drives the two L-shaped pulling plates 2571 to approach or move away from each other simultaneously, and further adjusts the positions of the L-shaped pulling plates 2571. When the C-shaped frame 242 drives the screw rods to engage with each other, the support plate 23 drives the disc plates 256 thereon through the hexagonal column 253 and the insertion rod 251 to be respectively located on the side of the longitudinal section of the L-shaped pulling plate 2571 far from the center of the bottom plate 1. Then, the operator manually rotates the adjusting bidirectional screw rod 2572 to drive the two L-shaped pulling plates 2571 to move away from each other, so that the L-shaped pulling plates 2571 drive the two disc plates 256 to move away from each other, thereby enabling the conical rubber wheel 2551 and the insertion rod 251 to withdraw from the inside of the screw rod, and further enabling the screw rods to rotate in the engaged state, which is convenient for testing the smoothness of the engagement of the screw rods.

[0055] When the present invention performs alignment and assembly on the screw rods, the following steps are further included: First step, the operator respectively places the female screw rod and the male screw rod inside the C-shaped frames 242 on the right side and the left side, and then manually pushes the adjusting frame 2461 upward, so that the adjusting frame 2461 drives the abutting roller 2462 to move upward to be located on the side of the screw rod. Then, the adjusting threaded rods 2473 on the left and right sides are manually rotated, and the adjusting threaded rods 2473 drive the abutting rollers 2462 to abut against the side of the screw rod, thereby clamping and locking the front and rear positions of the screw rod.

[0056] In the second step, the operator manually rotates the one-way threaded column 2453, and the one-way threaded column 2453 drives the abutment wheel frame 243 to move synchronously toward the axial position of the C-shaped frame 242. The abutment wheel frame 243 drives the abutment wheel 244 thereon to abut against the outer side surface of the rotating shaft of the screw, thereby locking the screw at the coaxial position of the C-shaped frame 242.

[0057] In the third step, the operator rotates the female screw and the male screw respectively so that the conical rubber wheel 2551 abuts against the two sides of the spiral boss of the male screw, thereby fixing the rotation angle of the male screw. Similarly, when the female screw is rotated until the spiral groove thereon is directly opposite to the top of the insertion rod 251, the insertion rod 251 is inserted upward into the spiral groove of the female screw under the push of the active spring at the corresponding position, thereby fixing the rotation angle of the female screw.

[0058] In the fourth step, the operator manually rotates the active bidirectional screw 265 to drive the movable plates 21 on the left and right sides to approach each other, and the movable plate 21 drives the bracket plate 23 to rotate 90° around the sliding column 264 on the side away from the bracket plate 23, and the movable plate 21 drives the bracket plate 23 to continue to move, so that the bracket plate 23 moves horizontally toward the center of the base plate 1 through the movable column 232, and then the bracket plate 23 drives the two screws to move and mesh together through the C-shaped frame 242.

[0059] In the fifth step, the operator manually turns the bidirectional screw 2572 to drive the two L-shaped pulling plates 2571 away from each other, so that the L-shaped pulling plates 2571 drive the two disc plates 256 away from each other, thereby allowing the conical rubber wheel 2551 and the insertion rod 251 to withdraw from the interior of the screw, and then the screw can rotate in a mutually meshing state, which is convenient for testing the meshing smoothness of the screw.

[0060] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still within the scope of protection of the present invention.
